Before the lock forms here illustratedV are specifically described, it is to` beunderstood that the invention here involvedhis no t limited tothe structural details or arrange-l n ment of parts here shown since locks embodying the present invention may take Various forms. It also is to be understood that the phraseology or terminology herein employed is for purposes of description and not of limitation since the scope of the present invention is denoted by the appended claims.

Those familiar with the state of the art will recognize that the present invention may be applied in many ways and different components thereof may be used in many types of locks, but it has been chosen to illustrate the same as a free-handle lock on an automobile door with an automatic rotor delocking action when the door is being closed.

STRUCTURE ASSOCIATED WITH ALL FORMS OF LOCKS Four forms of locks are disclosed: (1) Lock 10 in FIGS. 1- 12, (2) Lock 110 in FIGS. 13-24, (3) Lock 210 in FIGS. 28 and 29 comprising the lock in FIGS. 13-24 with the structure of FIGS. 28 and 29 substituted for a portion thereof, and (4) Lock 310 in FIGS. 30-41. Locks 10, and 310 are shown respectively in FIGS. l, 1,3 and 30 (FIGS. 13 and 30 being an enlarged portion of FIG. 1 with a dilerent lock substituted therein) as secured to a front door 14 on a conventional car body 12 having front and rear doors 14 and 16.

Each lock has an identical inside handle 26 movable between inside handle actuated position IA to unlatch door 14 to permit door opening, unactuated position IUA to keep door 14 latched in closed position, and locking position IL; an outside handle 30 in FIGS. l, 25 and 26 movable between outside handle actuated position OA to unlatch door 14 to permit door opening, and unactuated position OUA to keep door, 14 latched in closed position; lock key cylinder 2:2 in FIGS. l and 25-27 movable between actuated or lock unlocking position UL in FIGS. 2, 14, 25 or 3l to unlock the door, unactuated or neutral position KN in FIG. 27 for key insertion or removal, and another actuated or lock locking position L in FIGS. 9, 16, 26, or 33 to lock the door; and connecting mechanism movable between corresponding positions.

Both handlesv 26 and 30. will permit the door to remain latched in `door closed position when they are in the unactuated position, `and either will permit unlatching of the lock as the handle is moved to the actuated position so `that the door will be free to swing from the door closed to the door open position about hinges 14a mounting door 14 on car body 12.

Inside handle 26 is pivotable clockwise in FIG. l about its pivot 2Gb on door 14 from an unlatching or actuated position IA through a neutral or unactuated position IUA to a locked position IL so as to correspondingly actuate any of these locks, but here shown specifically in FIG. 1 as lock 10, by pushing its associated link 28 in FIGS. l, 3, l5, 28, or 32 toward the left by arm 26o of handle 26 to which link 28 is pivotally connected. The compression spring 27, located in FIG. 1 between stop lugs 14b and 14e on front door 14 is adapted to have its left end in FIG. l to be engaged by an upwardly extending arm 26a on the inside handle Y26V in the neutral position IUA and to be compressed as the handle 26 is swung clockwiseA to the locked position IL while it moves the left end of spring 27 away from lugr14b toward lug 14e. Hence, when handle 26.is manually moved toV the locked position IL, spring 27 will push the handle 26 counterclockfwise back to the neutraler unactuated position IUA when it is released.

Outside handle 30 (shown in FIGS. 1, 25 and 26) is swingable outwardly from the door in a clockvw'se direction in FIG. 25 about pivot 31b (located on arm 31 fixed to door 14) from anormal or unactuated solid line position OUA into an actuated, 4dot-dash line position OA, which position isdetermined by door handle portion Sila of door handle 30 engaging handle frame stop portion 14d of door 14 in FIG. 25, so as to control any of these locks by pulling the links 32 upwardly in FIG. 2, 14 or 31 from solid line unactuated position OUA to dot-dash line actuated position OA. This control is obtained by a bell crank 33 in FIG. 25 pivotally connected to arm 31 and link 32 by pivots 33a and 33b respectively. Arm 33C of bell crank 33 is adapted to be engaged and moved by a pin 34 secured -to handle 30 so that handle movement clockwise from solid to dot-dash line positions will cause corresponding counterclockwise movement of crank 33 and lifting movement of link 32; then, handle 30 may be swung counterclockwise back to the solid line position without eecting the OA position of link 32. Here, this counterclockwise return swing is caused by torsion spring '35 in FIG. 25 wound around pivot 31h and having its ends engaging handle 30 and arm 31. A spring, disclosed in more detail hereinafter in each lock 10, 116, 210 or 310 independently returns link 32 trom the actuated dot-dash line position OA to unactuated solid line position OUA in FIG. 25 at the appropriate time.

Lock key cylinder 22 of FIG. l, illustrated in FIGS. 25-27 with lock 110 and secured to door 14, permits actuation of lock key link 24 of any lock, but here shown xspecifically as lock 110, by lock key cylinder tumbler -actuated lug 22a so that any of these locks may be locked or unlocked by a key from the outside of the car. The key may turn the tumbler of lock key cylinder 22 about a longitudinal axis and the tumbler actuated lug 22a carried thereby through a 180 degree arc, as shown by the three positions K1, KN and K2 of lug 22a in FIG. 27 wherein position KN is the unactuated or neutral position and the other positions are the locking and unlocking positions. The lock key cylinder 22 is of usual construction so that the key can be inserted and removed therefrom only in the neutral position KN. Hence, the user inserts the key in position KN, turns it to position K1 or K2 so as to move the mechanism to unlocked or locked position, returns it to position KN while the mechanism remains in the selected position, and then removes the key. As the key is turned to move lug 22a from position KN to K1, bell crank 25, pivotally secured to door 14 by pivot 25a is FIG. 26, is swung counterclockwise to the solid line position K1 and link 24, pivotally secured thereto, is lifted to the solid line position K1 by bell crank 25 being moved downwardly to the solid line position K1 in FIG. 27 by lug 22a being rotated clockwise in slot 25a in bell crank 25. As the key is turned from unactuated or neutral position KN to position K2, bell crank 25 in FIG. 25 is swung clockwise to the solid line position and link 24 is lowered to the solid line position K2 in FIG. 25 by bell crank 25 being moved upwardly to the dot-dash line position K2 in FIG. 27 by lug 22a rotated counterclockwise in the slot 25a in the bell crank 25. However, it should be apparent that rotating the key back to neutral position KN from position K1 or K2 for key removal, does not move slot 25a and lever 25 away from the previously selected position K1 or K2. However, the vertical dimension of slot 25a does permit movement of slot 25a and lever 25, while lug 22a is in position KN, from position K1 or K2 in FIGS. 27 to position K2 or K1 respectively by lock 10, 110, 210, or 310 whenever desired, as will be brought out in more detail hereinafter, without movement of lug 22a from neutral position KN.

STRUCTURE OF LOCK IN FIGS. l-l2 In FIGS. l-l2, the dilerent components of the lock and striker 18 will be described in detail with respect to the unlocked position UL in FIGS. 2 to 8 inclusive. Here, striker 18 is secured in FIGS. l and 4 to the forward face of body post 12a in any suitable manner while llock 10 and all the component parts of lock 10 are carried by front door 14.

The lock 10 includes in FIGS. 2 and 3 a lock plate 40 having a rotor plate portion 40a and a remote plate portion 40b integrally connected together, and generally right angularly oriented with respect to each other with each being generally planar in form.

Lock 10 has a portion, located to the left of plate portion 40a in FIG. 4, coacting with the striker 18 secured to the body post 12a of car body 12. A Strap-like rotor housing y42 in FIG. 4 extends laterally from plate portion 40a through the rearward face of the door 14 and is secured thereto by rotor housing mounting tabs 42a in FIGS. 2 and 4 each extending through a slot in the plate portion 40a and welded =or otherwise secured thereto. Rotor 20 is rotatably mounted in rotor housing 42 by a pin 44 secured in rotor 20 in FIG. 4 and having its head rotatably mounted in housing 42 while a rotor shaft extension 20a in FIG. 4, formed integral with rotor 20, is rotatably mounted in the plate portion 40u. Secured to the right-hand end of this rotor shaft extension 20a in FIG. 4 and keyed against rotation relative thereto is a ratchet l46 having the same number of teeth as on rotor 20. Although six teeth are shown in the drawings, any satisfactory workable number may be used. Rotor housing 42 has integrally formed therewith two parallel end tabs 42b in FIG. 5 bent toward plate portion 40a from the section of housing 42 extending parallel in FIG. 4 to the plate portion 40a. A Wedge pin 48 in FIG. 5, extending generally parallel to the striker 18, is secured to rotor housing 42 by having its outer ends peened over the end tabs 42b. A wedge 50, telescoped over the wedge pin 48, is normally biased toward the right in FIG. 5 by the helical compression spring 52 located partially within a counterbore of wedge 50 and 1between the shoulder of the counterbore and the left-hand tab 42]) in FIG. 5. Lock 10, and its component rotor 20, rotor housing 42 and wedge 50, are adapted to telescope over striker 18 when the door 14 moves into its closed position so as to hold the door in closed and latched position and are adapted to telescope oi striker 18 when the door 14 is swung toward its open position about hinges 14a.

The lock 10 also has a plurality of operative parts located to the right of rotor plate portion 40a in FIG. 4. Locking lever 54 and pawl lever 56 in FIGS. 2 and 4 are pivotally mounted in FIGS. 2 and 4 on a common pivot 57 comprised of a stud 58 and sleeve 60. In FIG. 4, the left end of the stud 58 has an enlarged head located at the left of the plate portion `40a while the shank of the stud 58 extends through a hole in this plate portion. Sleeve 60 is telescoped over the shank of the stud from the right-hand end of the shank in FIG. 4 and through the mounting bores of the levers 54 and 56. The righthand end of the sleeve `60 has a ilange over which is upset the right-hand end of the shank of stud 58 to lock these levers to the plate 40 while permitting them to freely rotate about this pivot 57. A spiral spring 62 in FIGS. 2 and 4, secured at its inner end by two struck-up lugs 40d from plate portion 40a, engages at its outer end an arm 56a of pawl lever 56 to normally bias lever 56 clockwise in FIG. 2 about pivot 57 so that the pawl 56b of pawl lever 56 will be located between adjacent teeth of ratchet 46 in solid line, unactuated position UA of FIG. `2 so as to be maintained in latching engagement with this ratchet but is movable counterclockwise against the 'bias of spring 62 to the dot-dash line unlatching and actuated position A in FIG. 2. Rubber bumper 64 in FIGS. 2 and 3 encircles lug 40C integral with and struck up from plate portion 40h and is adapted to resiliently stop this clockwise movement before pawl 56b strikes bottom with a clicking sound between adjacent teeth of ratchet 46. Integral stop arm 56C of pawl lever 56 is adapted to engage this rubber bumper y64 so that the lock will be silent in operation and is adapted to travel in and along the length of slot 40m in plate portion 4Gb.

In this lock, position K1 in FIGS. 25-27 is the locked or actuated position and position K2 is the unlocked or actuated position. Key link 24, pivotally connected to lever 54, is shown in FIG. 2 in its actuated unlocking position K2 andlisadapted to be movedupwardly by keyactuated link 24, in the manner previously described, to actuated locking position K1, shown in solid lines in FIG.v 9, with locking lever 54 swinging clockwise about pivot'57 from its unlocked position UL to locked position L. Toggle spring 66 is pivotallyconnected at opposite ends to plate portion `40a and locking lever 54 to maintain the lever 54 in either of these two positions L or UL by having the spring Vend connected to lever 54 swing over center with respect to pivot 57'aud the other spring end. These two positions L and UL of lever 54 aredetermined by the engagement of the stop ann 54a of locking lever 54 with the opposite ends of slot 4ln in plate portion 40b through which it travels. Another arm-of locking lever 54vhas a cam face 54h adapted to engage or disengage a tooth of ratchet 46 at suitable times in the lock operation.

Outside handle 30 through its link 32 in FIGS. 2, 25 and 26 controls some Ifunctions of the lock. Link 32 is vshown in FIGS. 2, 25 and 26 in its solid line or unactuated position OUA, but as it moves upwardly to its dot-dash line or actuated position OA, it swings release lever 68, to which it is pivotally connected by rivet 69, clockwise about rivet 70 by which lever 68 is pivotally connected to plate portion 40a. As lever 63 swings clockwise in FIG. 2, the arcuate surface of its release cam 68a bears against the surface of pad 72a on release arm 72 to swing the release arm 72 counterclockwise about rivet 74 by which arm 72 is pivotally connected Vto plate portion 40a.

Suitable linkage operatively connects locking lever 54, pawl lever 56 and release arm 72 in FIG. 2. A rotor releasing toggle link 76 is pivotally connected at its right end by rivet 78 to pawl lever 56 in FIG. 2, a toggle link 80 is pivotally connected at its left end by rivet 82 to release arm 72, and a control link- 84 is pivotally connected at its upper end by pivot 86 with locking lever S4. The links 76, Sil and 84 are interconnected remote from the previously described pivots by a pivot 88 extending from a link 84 through a slotv76a in toggle link 76 and pivotallyconnected to toggle link Si). The control link 84 and its pivots 86 and 88 are formed of a continuous length of rod or wire stock with bent over ends, as shown in FIG. 7, but may be alternatively formed as a strip type strap with rivet type pivots. The bent over end forming pivot 88 extends through slot 76a in toggle linkr76 and through a hole in toggle link 80 to be peenedy on the right-hand side thereof in FIG. 7. Pivot 86 is formed by having the bent over end of the wire forming control link -84 extend through a hole in locking lever 54 while a C-Washer, clamping ring or snap ring 90 is snapped into a groove in control link 84 on the righthand side of locking lever 54.

Also, lock has parts actuated byinside handle 26 through link 2S in FIGS. l and 3. Remote control link 23 is. pivotally connected at its left end in FIG. 3 to remote lever 94 by rivet 95 and lever 94 is pivotally connected by rivet 96 to remote plate portion 4Gb. As the inside front door handle 26 swings clockwise in FIG. 1, it moves link 28 toward the left in FIG. 3 and swings remote lever 94 counterclockwise in FIG. 3 about rivet 96 from an actuated or door unlatched position IA to a neutral, latched, or unactuated position IUA and then to a locked position IL.

Lever 94 has integral arms 94a and 94b. Arm 94a is adapted to move stop arms 54a and 56C from the bottom to the top of 4their slots `4th; and 40m as lever 94 swings clockwise from locked position IL through neutral position IUA to actuated position IA so as to push arm 54a from locked position L to unlocked position UL and to push arm 56C from unactuated position UA to actuated position A. Arrn 9417 is adapted to push stop arm 54a yfrom the unlocked position lUL in FIGS. 2 and 3 at the topV of slot 44M to the locked position L in FIGS. 9 and l0 at the bottom of` slot 4611 as lever 94 swings counterclockwise from unactuated position IUA to locked position IL.

MODE OF OPERATION OFv LOCK IN FIGS. 1-125 The operation of this lock and door will `now beidescribed in detail.

In FIGS. 1-8, the door 14 is shown in its closed position with the lock 10 in its unlocked position UL and latohed or unactuated position UA and with the inner and outer door handles 26 and 30 in their unactuated positions IUA and OUA in the solid linek with stop arms 54a and 56e limit stopped against Vthe upper end of slot 40u and the lower end ofslot 40m respectively in FIG. 3.V Then, door 14 is kept in its closedy position and prevented yfrom swinging on hinges 14a outwardly to the open position by the pawl lever 56 being urged clockwise about pivot 57 in FIG. 2 intov its solid line, unactuated position UA -by the spring 62 to keep pawl S6b in latchingposition between adjacent teeth of ratchet 46 with pawl face 561' latched against one of the teeth. Since swinging of door 14 to its open position requires rotor housing 42V in FIG. 5 to rnove toward the left relative to the relatively stationary striker 1S, any opening movement will tend to rotate rotor 20 clockwise in FIG. 5 and to rotate ratchet 46 clockwise in FIG. 2. Integral pawl -face 56r of pawl 56b on pawl lever 56 engages in unactuated position UA with the side of a tooth on ratchet 46 to prevent this clockwise rotation of ratchet 46 to keep the door in its closed position since spring 62 urges pawl lever 56 clockwise into this latching position.

fDoor 14 Vmay be easily opened Vand swung from the door closed to the door open position. `One need merely move either the inside or outside handle 26 or 39 from its unactuated position IUA or OUAYto actuated position IA Vor `OA so as to swing pawl lever 56 counterclockwise about pivot 57'in FIG. 2 and `to move pawl 56b and the other component parts from their solid line, latched, unactuated positions UA in FIG. 2 to their actuated or unlatched dot-dash line positions A in FIGS. 2 and 3. Inside handle 26 is swung counterclockwise in FIG. l, link 28 is pulled toward the right from the solid line unactuatedY position IUA to the `dot-dash line actuated positions IA in FIG. 3 so that lever arm 94a is swung clockwise in FIG. 3 from the solid line position to the dot-dash line position to engage stop arm 56C and ,swing pawl lever 56 counterclockwise in FIG. 2 about pivot 57 to swing pawl 56h and its pawl face 56r outwardly to the dot-dash line position to travel from the latched or unactuated position UA to the unlatched or actuated position A and stop arm 56C limit stops against the upper end of slot 40m in FIG. 3. If stop arm 54a has been in the locked position L at the lower end of slot 4011 in FIG. 3, arm 94a will carry it'to the unlocked position UL at the upper end of slot 44m. Then, ratchet 46 is free to rotate so that rotor 20 in FIG. 5 may rotate clockwise and will be permitted to move toward the left in FIG. 5 so that the door 14 may be swung to its open position. If the lock lil is to be unlatched :by the outside handle 3i), one must swing outside handle 30 outwardly in FIGS. l and 25 lfrom its unactuated position OUA to its actuated position OA to move link 32 upwardly from the solid to dot-dash line position in FIGS. 2, 25 and 26 to swing release leverV 63 in FIG. 2 clockwise about pivot 70 so that release cam 68a will push pad 42a toward the right to FIG. 2, release arm 72 will swing counterclockwise about pivot 74, and toggle link will push toggle link 76 toward the right in FIG.

2 by pivot 88 engaging the right end of slot 76a toV swing pawl lever 56 counterclockwise about pivot 57 against the bias of spring 62'so as to swing pawl 56b and its pawl `face 56r from the latched, unactuated position UA to the unlatched, actuated position A and thus move all of these` parts from solid line position UA to dot-dash line position A in FIG. 2 so that ratchet 46.is

free to rotate and the door will open n the same manner.

After the door has swung outwardly to its open position, it may be swung or slammed closed without touching either the inside or outside handle 26 or 30. After the door has opened and the door opening handle 26 or 30 has been released, cam 56h will be biased clockwise in FIG. 2 from the dot-dash line actuated position A to the solid line unactuated position UA by spring 62 so as to move from the unlatched to the latched position. When the door 14 is swung from its open to its closed position, the lock and its rotor body 42 will move toward the right in FIG. relative to the relatively stationary striker 18 so that the travel of rotor 20 under the striker 18 will cause the rotor 20 to rotate counterclockwise as the door moves toward its closed position. As rotor 20 rotates counterclockwise, ratchet 46 in FIG. 2 rotates counterclockwise so that the teeth thereof successively force the pawl lever 56 to oscillate about pivot 57 by their indi-vidual engagements with the pawl face 56s of the pawl 56h until the door is fully closed. Then, spring 62 again biases the pawl lever 56 clockwise until pawl 56b is iirmly seated in its latching or unactuated position UA between adjacent teeth of ratchet 46 with pawl face 56r latched firmly against a ratchet tooth. Note that slot 76a merely reciprocates back and forth over pivot 88 so that release arm 72 and outside handle 3i) are not Vmoved out of unactuated position OUA by the door closing action.

When the number and design of teeth in rotor 20 is so chosen that it is desirable to exert an upward force in FIG. 5 on the lock and rotor housing 42 to properly seat the rotor 20 against the striker, wedge 50 with its compression spring 52 is preferably used. Then, as the yrotor housing `42 telescopes over the relatively stationary striker 18 in FIG. 5, beveled surface 18a of the striker 18 in FIG. 5 will coact with beveled surface 50a of the wedge 50 to Wedge the lock and rotor housing 42 upwardly as the door moves toward its fully closed position against the compression of spring 52 so that the proper coaction will take place between the teeth of striker 18 and rotor 26 so that no vertical motion of the door will be allowable.

The lock r may be moved to its locked position L in FIG. 9 by inside handle 26. When inside handle 26 is in its neutral, unactuated and unlocked position IUA, remote lever 94 is in the solid line position of FIG. 10. As inside handle 26 is swung clockwise in FIG. 1 to the locked position IL, remote control link 2S is moved toward the left in FIG. l and remote control lever 94 is swung counterclockwise in FIG. 3 from the solid line unactuated position IUA to dot-dash line locked position IL so that arm 94b moves stop arm 54a from the upper end of slot 40n down against the lower end of slot 40u from the solid line unlocked position UL in FIGS. 2 and 3 to the solid line locked position L in FIGS. 9 and 10 to swing locking lever 54 clockwise from the solid line position ULv in FIG. 2 to the solid line position L in FIG. 9 to pull toggle links 76 and 80 to the solid line position in FIG. 9 by control link 84. Locking lever 54 is movable between positions UL and L without key actuated movement of the tumblers of lock key cylinder 22 because (l) lug 22a is in the neutral or unactuated position KN in FIG. 27 since the key has returned it to this position prior to key removal from lock key cylinder 22, and (2) the vertical size of slot 25a in FIG. 27 permits bell crank 25 to move from unlocked position K2 to locked position K1 without movement of lug 22a from neutral or unactuated position KN and without key actuation of the tumblers of lock key cylinder 22. Now, the lock is in the locked position L and it is impossible to unlatch the look and open the door by the outside handle 30. If the outside handle 30 is swung outwardly in FIGS. 1 and 25 from its unactuated position OUA to its actuated position OA so as to move outside handle link 32 upwardly from the solid line to the dot-dash line position in FIGS. 9 and 25, pivot 88 in FIG. 9 will merely travel between the solid line and dot-dash line position in slot 76a but will not cause disengagement of pawl 56b from between the teeth of ratchet 46 so as to move it from the latched or unactuated position UA to the unlatched or actuated position A to permit door opening. After inside handle 26 has been manually actuated to move lever `94 from solid line position IUA to dot-dash line position IL in FIG. 10 to lock the door and then inside handle 26 is released, spring 27 in FIG. l, pushing against arm 26a, will return handle 26 in a counterclockwise direction to the neutral position IUA and lever 94 to its solid line neutral position IUA in FIG. 10.

This construction also prevents unauthorized entry of the automobile by an intruder through the unlocked door if the car occupant quickly manipulates the inside handle 26. The occupant may be safe even if the intruder has had time to move the outside handle 30 to the fully actuated position OA, has withdrawn pawl `56h from the latching or unactuated position UA between adjacent teeth of ratchet 46 to unlatching or actuated position A, and the rotor 20 has rotated of a rotation clockwise in FIG. 5 to partially open the door to the safety position with the rotor 20 held between the iirst and second tooth from the left in FIG. 5 on striker 13. If the occupant grabs the inside handle 26 and swings it clockwise in FIG. l to the locked position IL before rotor 20 has left the safety position, this movement of handle 26 will swing lever 94 counterclockwise to the dot-dash line position IL in FIG. l0 to lock the door by swinging locking lever 54 from unlocked position UL in FIG. 2 to locked position L in FIG. 9. This movement of lever 54 causes control link 84 to raise pivot 88 to break the toggle formed by the toggle links 76 and 80 by moving them to the solid line position of FIG. 9 so as to break the operative connection for-med by the rigid toggle links 76 and l80 in FIG. 2 between outside handle 3i) and latching pawl 56b. Then, spring 62 will rotate pawl lever 56 clockwise to the solid line or unactuated position UA in FIG. 9 to snap its pawl face 56r into latching engagement between adjacent teeth of and with a tooth of ratchet 46. This locking action will automatically take place independently of the position of outside handle 30; and once the door is locked, the outside handle 30 may be freely moved between unactuated and actuated positions OUA and OA without opening the door. `Note that the car occupant can hold the door closed and lock the door by grasping only one inside handle 26, by both hands if necessary; and need not hold the door closed by grasping the handle with one hand while trying to actuate a separate inside lock button with the other.

In lock 10, the door may also be locked from outside the automobile by the use of a key in the lock key cylinder 22. When the proper key is inserted in the lock 22 in FIGS. l, 25 and 26 and is rotated clockwise in FIG. 27, the tumbler yactuated lug 22a of the lock cylinder 22 will rotate clockwise in FIG. 27 from position KN to position K1 to lift link 24 from the unlocked, dot-dash line position K2 in FIG. 26 to the actuated, locking, solid line position K1 in FIG. 26 to move the component parts of the lock from the solid line, unlocked position UL in FIG. 2 to the solid line, locked position L in FIG. 9 to lock the door. Then, pivot 38 will be pulled upwardly by control link 84 and will raise toggle links 76 and Sii to the solid line position in FIG. 9 to provide the same locking action as mentioned in regard to inside handle 26.

The door may be unlocked by key or by manual actuation of inside lever 26. If the key is inserted into lock 22 and is turned counterclockwise in FIG. 27 from neutral position KN to unlocked position K2, link 24 is forced downwardly from the locked, dot-dash line position K1 in FIG. 25 and locked solid line position L in FIG. 9 to the actuated unlocking solid line position UL in FIG.

T1 2 and position K2 in FIG. 25. If inside handle 26 is swung counterclockwise in FIG. 1 from unactuated position IUA to actuated position IA, it swings lever 94 clockwise from the solid line position IUA in FIG. l toward the dot-dash line position IA of FIG. 3 to move arm 54a between the positions L and UL in these drawing figures.

Also, if outside handle 30 is jammed by a crash or for any other reason in actuated position OA, unactuated position OUA, or any intermediate position, while locked or unlocked, the car occupant will still be able to open the door, although the door will not automatically open as the result of any such jamming of the outside handle. Pawl 56b may be unlatched at any time by moving inside handle 26 counterclockwise in FIG. 1=to the actuated position IA, and this motion will move lever 54 to unlocked position UL, if it is in locked position L, and will move pawl 56b to its unlatched or actuated position A independently of the location of outside handle 30.

Lock has automatic delocking. If the door 14 is swung to its open position, locked by either inside handle 26 or by key actuation of lock key cylinder 22, and then the door 14 is swung to its closed position without touching either handle 26 or 30, the lock 10 will operate properly, the lock 10 will be in unlocked position UL when closed, and the door can be then opened by outside handle 30. This locking action will move the lock parts to the solid line, locked position L of FIG. 9 in the manner previously described. Swinging the door to its closed position will automatically delock rotor of the lock 10 and move the parts to the solid line, unlocked position UL of FIG. 2. As the door 14 moves toward the closed position, the lock and its rotor housing 42 in FIG. 5 will move toward the right relative to relatively stationary striker 18 so that rotor 20 rotates counterclockwise and this causes ratchet 46 to rotate counterclockwise in FIGS. 2 and 9 so that the component lock parts move from the solid line position in FIG. 9 through the dot-dash line position in FIG. ll to the solid line positions in FIG. 2. Counterclockwise rotation of ratchet 46 performs two functions. First, cam face 54h, providing a small lever arm about pivot 57, is forced, by the immediately clockwise located tooth profile of ratchet 46, upwardly in FIGS. 9 and 1l torotate locking lever 54 in Ia counterclockwise direction from the solid line, locked position L in FIG. 9 through the solid line position in FIG. 1l to the solid line, unlocked position UL in FIG. 2 to automatically unlock the lock by pushing pivot S8 downwardly to straighten the toggle formed by links 76 and S0 by moving them between the solid line positions of FIGS. 9 and 2. Locking lever 54 is movable between positions L and UL without key actuated movement of the tumblers of lock key cylinder 22 because (l) lug 22a is in the neutral or unactuated position KN in FIG. 27 since the key has returnedV it to this position prior to key removal from lock key cylinder 22, and (2.) the vertical size of slot 25a in FIG. 27 permits bell crank 25 to move from locked position K1 to unlocked position K2 without movement of lug 22a from neutral or unactuated position KN and without key actuation of the tumblers of lock key cylinder 22. Second, counterclockwise rotation of ratchet 46 causes the immediately clockwise located tooth profile of the ratchet to act against pawl face 56s of pawl 56b to swing pawl lever 56 about pivot 57 in a counterclockwise direction against the resilient bias of spring 62 from its unactuated, latching position UA toward its actuated, unlatching position A so that rotor 20 may rotate properly and let the door move fully to its closed position at which time spring 62 returns pawl lever 56 in a clockwise direction to urge the pawl 56b inwardly between adjacent teeth of ratchet 46 to latched or unactuated position UA. Now, actuation of outer handle 30 will open the door since unlocking has occurred.

If the door 14 is open, the door is locked and the outside handle 30 is swung to its actuated position OA, as shown by the dot-dash lines in FIG. 9, the lock 1li will still properly operate when the door is slammed to its closed position while the outside handle 30 is held in its actuated position OA and the unlocked door then can be opened from the outside by handle 30. As the door moves toward its closed position, the lock parts are in the dot-dash line or actuated position OA of FIG. 9 with pivot 88 near the right end of slot 76a in FIG. 9-but not against it. As the counterclockwise rotation of the ratchet 46 causes the parts to move through the solid line position of FIG. l1, the outside handle 30 will remain substantially in its actuated position OA because of the design of links 76, and 84. If there is any tendency to urge release arm 72 in the clockwise direction in FIG. 9 or 1l to move the outside handle 30 back toward its unactuated position OUA, there will be sufiicient give in spring 62 to permit the outside handle 30, if sufficient pressure is applied thereto, to remain in its actuated position OA. Also, as the parts approach the dot-dash line or actuated position OA in FIG. 2, the pivot 88 should preferably engage against the right end of slot 76a so as to forceably move pawl lever 56 counterclockwise about pivot 57 against the bias of spring 62 to swing the pawl 56b outwardly toward its actuated or unlatched position A beyond the outer edge of the teeth of ratchet 46 because the ratchet 46 should be preferably in a free wheeling position when the door is in unlocked position UL and the outside handle 30 is in its actuated position OA in the manner shown by dot-dash lines in FIG. 2 so that the door will easily open when the outside handle 30 is actuated. Also, cam face 54]) is forced out by a tooth prole on ratchet 46 to rotate the locking lever 54 counterclockwise to unlock the lock by swinging lever 54 to unlocked position UL to push pivot 88 downwardly by control link 84. Hence, the lock 10 Will be automatically moved to unlocked position UL as the door closes by moving the lock parts from the locked position L of FIG. 9 to the unlocked position UL of FIG. 2 through the FIG. l1 position whether the outside handle 30 is in actuated position OA, unactuated position OUA, or an intermediate position, and the lock 10 may be unlatched by actuating outside handle 30 to move pawl 56b to an actuated and unlatched position A.

The door may also be easily locked from the outside by inserting the proper key in cylinder lock 22 after the door has been moved to its fully closed position. Then, rotation of -the key clockwise in FIG. 27 will move lug 22a from position KN to position K1 to cause the parts to assume the locked position K1 in FIGS. 25 and 26 and the locked position L in FIG. 9. Then, the outside handle 30 is free to move between its positions OA and OUA or may have an idling action, and this 4movement will not unlatch the door as the operator moves it between unactuated position OUA and actuated position OA. During this movement, release arm 72 oscillates around pivot 74 so that release lever link Si) moves pivot 8S back and forth along the length of slot 76a. However, this lost movement of pivot 88 in slot 76a should preferably be restricted by a suitable end stop, formed by engagement of stop portions 14d and 36a in FIG. 25, limiting the movement of outside handle 30 and link 32 Within a desirable range. For example, it is preferred that when the outside handle 30 is in its actuated position OA, as shown in dot-dash lines in FIG. 9, and these stop portions 14d and 3dr; are engaging, a gap 76b will still remain between pivot 88 and the right-hand end of slot 76a so that anyone attempting to unlock the door will not be ableto begin to move pawl 56h even slightly out of its fully latched or unactuated position UA shown in FIG. 9.

Since this gap 76b exists, it should also be apparent that when the door is locked, with the parts in the so-lid line position of FIG. 9, the outside handle 39 may be moved between actuated and unactuated positions OA and OUA, shown by dot-dash and solid line positions in FIG. 9, without causing damage to the lock components.

In lock 10, it should be noted that the construction and coaction of control link 84 coacting with slot 7611 and toggle links 76 and 80 controls the delocking and locking action, controls the toggle action, prevents the toggle from swinging over center in the downward direction, prevents unauthorized unlatching movement of pawl 56b from unactuated position UA by actuation of outside handle 30 after the door is closed and locked, permits door slamming without disturbing the outside handle 30 in the unactuated position OUA, enables the occupant to prevent the entry of intruders, permits the door to be opened from the inside by movement of inside handle 26 to actuated position IA even when the outside handle 30 is jammed in any position, and permits the lock to have all desirable operating characteristics.

Now it should be apparent that in FIGS. 1-12 there has been disclosed a lock or latch mechanism having latch means including rotor 20 for latching cooperation with keeper means or striker 18, detent means or pawl lever 56 pivotally mounted on an axis formed by pivot 57 and cooperable with the ratchet 46 of the latch means for releasably detaining such latch means in latching cooperation with the keeper means, manually operable control means including outside handle link 32, means, including links 76, 84 and 88, operatively connecting said control means with said detent means and movable into one position shown as unlocked position UL for release actuation of said detent means upon manual operation of said control means with consequent release of said latch means and into another position shown as locked position L for preventing said release actuation by said manual operation, and a lever 54 pivotally connected on the axis formed by pivot 57 and responsive to relative movement between said latch means and keeper means during door closing for automatically moving said connecting means from said other position L to said one position UL. Also, the axis of said detent means and the axis of said lever are coaxial on pivot 57, ratchet V46 of said latch means has a plurality of circumferentially arranged teeth, said detent means has a pawl portion 56b engageable with said latch means between a pair of adjacent teeth, and said lever 54 has a cam face portion 54b engageable with said latch means between a different pair of adjacent teeth in FIG. 9.

STRUCTURE OF LOCK IN FIGS. 13-24 The diterent components of the lock 110 and striker 118 will be described in detail with respect to the unlocked position UL in FIGS. 14, 15, 22, 23 and 24. Here, striker 1'18 in FIGS. 22, 23 and 24 is adapted to be secured to the forward face of body post 12a in any suitable manner, such as striker 18 is secured in FIGS. l and 4, while lock 110 and all the component parts of lock 110 are carried by front door 14.

Lock 110 includes in FIGS. 14, 15, 23 and 24 a base frame including a lock plate 140 having a rotor plate portion 14011 and a remote plate portion 14011 integrally connected together, and generally right angularly oriented with respect to each other with each being generally planar in form. A door lock cover 141 (having some portions shown in solid line in FIG. 14 and other portions cut away with the remaining plate outline shown in dot-dash lines), extending parallel to plate portion 14011, :has integrally formed therewith at its lower left end in FIG. 14 a strap portion 14111 in FIGS. 14 and 23 extending at right angles to cover 141 and portion 14011 and having a shoulder abutting against portion 14011 to space apart portion 14011 and cover 141; a mounting tab 141b extending from this shoulder, through a slot in portion 14011, and bent at right angles to strap portion 14111 to keep the shoulder against portion 14011; and a shoulder formed at the lower right end of cover 141 in FIG. 14 bearing against remote plate portion 140b with a mounting tab 141e in FIGS. 14, 15 and 24 extending from this shoulder, through a slot in portion 140b and bent at right angles to cover 141 to keep the shoulder against portion 140b. Plate portion 114011 has an aperture 140r in FIGS. 14, 23 and 24 having its upper portion covered by door lock cam stud plate 143 in FIGS. 14, 23 and 24 welded to portion 14011 around the edges thereof. A strap-like strike plate and rotor housing 142 in FIGS. 22, 23 and 24 extends laterally from plate portion 14011 through the rearward face of the door 14 and is secured to portion 14011 by lower rotor housing mounting tab 14211 extending through the lower portion of aperture 140r and welded to the face of portion 14011 remote trom housing 142 and by upper rotor housing mounting tab 142b located within a struck up recess 14011 in plate portion 14011 in FIGS. 23 and 24 closed by plate 143 with tab 14219 sandwiched between and welded to both plate 143 and portion 14011. Plate 1143 has an arcuate lower edge forming with the lower portion of aperture 1401 and the top of tab 14211 a circular aperture '140s in FIGS. 14, 23 and 24.

Lock has a portion, located to the right of plate portion 14011 in FIG. 23, coacting with the striker 11S secured to the body post 1211 of car body 12. This includes strap-like rotor housing 142 in FIGS. 22, 23 and 24 and rotor rotatably mounted in rotor housing 142 on a sleeve "145 secured to rotor housing 142 and to door lock cover 141 by -a door lock rotor stud '144 having a head at its right end in FIG. 23, telescoped within sleeve 145 upon which rotor 120 is rotatably mounted, and having its left end in FIG. 23 peened over upon a ange of sleeve 145. integrally formed with rotor 120 for rotation therewith and axially spaced therefrom is a ratchet 146 in FIGS. 14 and 23 having the same number of teeth as rotor 120 and a circular ange 120!) located axially therebetween and rotatable within a circular aperture 140s. Although four teeth are shown in the drawings on rotor 120 and ratchet 146, any satisfactory workable number may be used. Hence, lock 110 and its component rotor 120, and rotor housing -142 are adapted to telescope over stationary striker 118 when the door 14 moves into its closed position so as to hold the door in closed and latched position and are adapted to telescope oit striker 118 when the door 14 is swung toward its open position about hinges 1411.

Lock 110 also has a plurality of operative parts located to the left of rotor plate portion 14011 in FIG. 23, which parts are more clearly shown in FIGS. 14 and 15. Locking lever 154 and lifting cam lever 156 in FIG. 14 are pivotally mounted on pivots 159 and '157 respectively. Long cam 153 and short cam 155 are also pivotally mounted on pivot 157. Pivot 159 is a rivet rotatably mounting lever 154 to lower mounting tab 14211 and plate portion 14011. Pivot 157 comprises a stud 158 and sleeve in FIGS. 14 and 23.- In FIG. 23, the right end of the stud 158 has an enlarged head located at the right of stud plate 143 while the shank of the stud 158 extends through a hole in this plate. Sleeve 160 is telescoped over the shank of the stud from the left-hand end of the shank in FIG. 23 and through the mounting bores of the cams l153 and 155 and of the lever 156. The left-hand end of the sleeve 160 has a ange over which is upset the left-hand end of the shank of stud 158 to lock this lever and these cams to the plate 140 while permitting them to freely rotate about this pivot 157. Spiral springs 161, 162 and 163 in FIGS. 14 and 23, secured at their inner ends by two struck-up lugs 14011 from plate portion 14011, respectively engage at their outer ends long cam 153, cam 15617 of lifting cam lever 156 and short cam 155 to normally bias these cams and lever counterclockwise in FIG. 14 about pivot y157 so that the cams 153, 155 and 156b will be located between adjacent teeth of ratchet 146 in solid line, unactuated position UA of FIG. 14 so as to be maintained in latching engagement with this ratchet but are movable clockwise against the bias of springs 161, 162 and 163 to the dot-dash line, unlatching and actuated position A in FIG. 14 by keeper flange 15611' of lever 156 as lever 156 is swung clockwise. Integral arm 156C of lifting cam lever 156 is adapted to travel during this movement through and along the length'of detent 140m formed by a struck-up portion in plate portion 14011, as seen in FIGS. 14, 15 and 24.

-In lock 110, position K1 in FIGS. 25-27 is the locked or actuated position L and position K2 is the unlocked or actuated position UL. Key link 24, pivotally connected to lock slide 165, is shown in FIGS. 14 and 15 in its actuated unlocking position K2 and is adapted to be moved upwardly by key actuated link 24 in the manner previously described, to actuated locking position K1, shown in solid lines in FIG. 16, with lock slide 165 swinging locking lever 154 counterclockwise about pivot 159 from its unlocked position UL to locked position L. Lock slide 165 has an outwardly extending lug 165a fitting loosely into slot 154C of locking lever 154 in FIGS. 14 and 15 to convert the vertical reciprocation of slide 165 into oscillation of locking lever 154 about pivot 159 between unlocked position UL in FIGS. 14 and 15 and locked position L in FIGS. 16 and 17.' Lock slide 165 is slidably secured to lock plate 140 for vertical movement in FIGS. 14 and 15 between these positions by parallel surfaces including a lug 165b of slide 165 riding on rotor plate portion 14011, bearing lug 165e of slide 165 riding against edge 140']c of struck-up pad 146g struck-up from remote plate portion 14017, and surface 165d bearing against cover 141. Slide 165 is kept entrapped against the face of remote plate portion 140!) in FIGS. 14 and 15 by lug 141d struck-up from cover 141 and by remote lever 194 pivotally connected to pad '140g by rivet 196. Locking position L and unlocking position UL are determined respectively by lug 165,7c of slide 165 engaging in FIG. 17 against edge 14511 of struck-up pad 145g and by the end 154d of locking lever 154 engaging strap portion 141a in FIGS. 14 and 23 as an end stop. Toggle spring 166 in FIG. 15 is pivotally connected at opposite ends to plate portion 1401 and lock slide 165 to maintain the slide 165 and lever 1154 in either of these two positions by having the spring end connected to slide 165 swing over center with respect to the other spring end. Another arm of locking lever 154 has a cam face 154b in FIG. 16 adapted to engage or disengage a tooth of ratchet 146 at suitable times in the lock operation,

In lock 116, the outside handle 30 through its link 32 in FIGS. 14, and 26 controls some functions of the lock. Link 32 is shown in FIGS. 14, 25 and 26 in its solid line or unactuated position OUA, but as it moves upwardly to its dot-dash line or actuated position OA, it swings release lever 172, to which it is pivotally connected by rivet 169, clockwise about rivet 174 by which lever 172 is pivotally connected to plate portion 141111.

A linkage operatively connects locking lever 154, lifting cam lever 156 and `release arm i172 in FIGS. 14, 20 and 2l. A rotor releasing toggle link 176 is pivotally connected at its right end by rivet 178 to lifting cam lever 156 in FIGS. 14 and 20, a toggle link 18) is pivotally connected at its left end by rivet 182 to release arrnA 172, and a control link 184 is pivotally connected at its lower end by pivot 156, formed by a rivet, with locking lever 154. The links 176, 180 and 184 are interconnected remote from the previously described pivots by a pivot 188 formed by a rivet pivotally connected to link I184, extending through a slot 176:1 in toggle link 176 and pivotally connected to toggle link 180. Control link 184 is shown as a strip type strap but may instead be formed of rod or wire stock, like link 84. Y

Lock 110 also has parts actuated by inside handle 26 through link 28 in FIGS. 13 and 15. Remote control link 28 is pivotally connected at its left end in FIG. 15 to remote lever 194 by rivet 195 and lever 194 is pivotally connected by rivet 196 to pad 140g on remote plate portion 140b. As the inside front door handle 26 swings clockwise in FIGS. 1 and 13, it moves link 28` toward the left in FIG. 15 and swings remote lever 19'4 clockwise in FIG. 15 about rivet 196 from an actuated or door unlatched position IA to a neutral, latched, or unactuated position IUA and then to a locked position IL.

Lever 194 has integral arm 194C. Arm 194C adapted to move downwardly lifting cam lever arm 156C and locking slide `165 from the locked and unactuated positions L and UA of FIG. 17 to the unlocked and actuated positions UL and A of FIG. 15 as lever 194 swings counterclockwise from locked position IL through neutral position IUA to actuated position IA so as to push lock slide 165, by engagement of arm 194e` with lug 165g on slide 165, from locked position L to unlocked position UL and to push arm 156C from unactuated position UA to actuated position A.

scribed in detail.

FIGS. 13, 14 and 15 show the door 14 in its closed position with the lock 1-10 in its unlocked position UL and latched or unactuated position UA and with the inner and outer door handles 26 and 30 in their unactuated positions IUA and `OUA in solid line. Then, door 14 is kept in its closed position and prevented from swinging on hinges 14a outwardly to the open position by the long cam 153, short cam and lifting cam lever 156 being urged counterclockwise about pivot 157 in FIG. 14 into their solid line, unactuated position UA by the springs 161, 163 and 162 respectively to keep cams 153V, 155 and 156b in latching position between adjacent teeth of ratchet 146 with cam faces 1531', 155r and 156r latched against one of the teeth. Since swinging of door 14 to its open position requires rotor housing 142 in FIG. 24 to move toward the right relative to the relatively stationary striker 1'18, any opening movement will tend to rotate rotor 120 counterclockwise in FIG. 24 and to rotate ratchet 146 clockwise in FIG. 14. Integral cam face 156r of cam 15617 on lifting cam lever 156 and cam faces 153b and .15511 of cams 153 and 155 engage in unactuated position UA with the side of a tooth on ratchet 146 to prevent this clockwise rotation of ratchet 146 to keep the door in its closed position since springs 161, 163 and 162 urge cams 153 and 155 and lifting cam lever 156 counterclockwise into this latching position.

One can easily open the door 14 and swing it from door closed to door open position. He need merely move either the inside or outside handle 26 or 30 from its unactuated position IUA or OUA to actuated position IA or OA so as to swing lever 156 clockwise about pivot 157 in FIG. 14 to swing clockwise cam 156b of lever 156 to swing clockwise cams 153 and 155 by keeper flange 1S6d of lever 156, and to move the other component parts from their solid line, latched, unactuatcd positions UA in FIG. 14 to their actuated or unlatched dot-dash line positions A in FIGS. 14 and 15. Inside handle 26 is swung counterclockwise in FIG. 1, link 28 is pulled toward the right from the solid line unactuated position IUA to the dotdash line actuated position IA in FIG. 15 so that lever arm 194C is swung counterclockwisein FIG. 15 from the solid line position to the dot-dash line position to engage arrn 156C and swing lifting cam lever 156 clockwise in FIG. 14 about pivot 157 to swing cams 153, 155 and 156 and their cam faces 153r, 155r and 156r outwardly to the dot-dash line position to travel from the latched or unactuated position UA to the unlatched or actuated position A. If lock slide lug 165g has been in the locked position L in FIG. 17, arm 194C will carry it downwardly to the unlocked position UL in FIG,Y 15. Then, ratchet 146 is free to rotate so that rotor 120 in'FIG. 24 may rotate counterclockwise and will be permitted to move toward the right in FIG. 24 so that the door 14 may be swung to its open position. If the lock 110 is to be unlatched by the outside handle 30, one must swing outside handle 30 outwardly in FIG. 1 from its unactuated position OUA to its actuated position OA to move link 32 upwardly from the solid to dot-dash line position in FIG. 14A to swing release arm 172y clockwise about pivot 174i s that toggle link 180 will push toggle link 176 toward ythe right in FIG. 14 by pivot 188 engaging the right end of slot 176a to swing not only lifting cam lever 156 but also cams 153 and 155, by keeper flange 156d engaging these cams, clockwise about pivot 157 against the bias of springs 161, 162 and 163 so as to swing cams 153, 155 and 156b and their cam faces .153r, 155i', and 156r from the latched, unactuated position UA to the unlatched, actuated position A and thus move all of these parts from solid line position UA to dot-dash line position A in FIG. 14 so that ratchet 146 is free to rotate and the door will open in the same manner.

In lock 110, after the door has swung outwardly to its open position, it may be swung or slammed closed without touching either the inside or outside handle 216 or 30. After the door has opened and the door opening handle 26 or 30 has been released, cams 153, 155 and 156b will be biased counterclockwise in FIG. 14 from the dot-dash line actuated position A to the solid line unactuated position UA by springs 161, 163 and 162 so as to move from the unlatched to the latched position. When the door 14 is swung from its open to its closed position, the lock and its rotor body 142 will move toward the left in FIG. 24 relative to the relatively stationary striker 118 so that the travel of rotor 120 under the striker 118 will cause the rotor `120 to rotate clockwise as the door moves ytoward its closed position. As rotor 120 rotates clockwise, ratchet 146 in FIG. 14 rotates counterclockwise so that the teeth thereof successively force cams 153, 155 and 156b to oscillate about pivot 157 by the individual teeth engagements with the cam face 153s, 155s and 156s of cams 153, 155 and 156b until the door is fully closed. Then, springs 161, 162 and 163 again bias the lifting cams 153, 156b and 155 counterclockwise until they are firmly seated in their latching or unactuated position UA between adjacent teeth of ratchet 146 and these cams individually take up the clearance by having their cam faces 153:; 155r and 156r latched lirmly against a ratchet tooth. Note that slot 176a merely reciprocates back and forth over pivot 188 so that release arm 172 and outside handle 30 are not moved out of unactuated position OUA by the door closing action.

As the rotor housing 142 telescopes to the left over the relatively stationary striker 118 in FIG. 24, top surface 118b of the striker 118 in FIG. 24 will coact with rotor housing surfaces '142d so that the proper coaction will take place between the teeth of striker 118 and rotor l? so that no vertical motion of the door will be allowa e.

One may move lock 110 to its locked position L in FIGS. 16 and 17 by inside handle 26. When inside handle 26 is in its neutral, unactuated and unlocked position IUA, remote lever 194 is in the solid line position of FIG. 17. As inside handle 26 is swung clockwise in FIG. 1 to the locked position IL, remote control link 28 is moved toward the ieft in FIGS. 13 and 17 and remote control lever 194 is swung clockwise in FIG. 17 from the solid line unactuated position IUA to dot-dash line locked position IL so that arm "194C moves upwardly lock slide 165, by arm engagement with shoulder 165k of slide 165, from the solid line unlocked position UL in FIGS. 14 and 15 to the solid line locked position L in FIGS. 16 and 17 to swing locking lever 154 counterclockwise from the solid line position UL in FIG. 14 to the solid line position L in FIG. 16 to pull toggle links 176 and 180 to the solid line position in FIG. 16 by control link 184. Locking lever 154 is movable between positions UL and L without key actuated movement of the tumblers of lock key cylinder 22 because (l) lug 22a is in the neutral or unactuated position KN in FIG. 27 since the key has returned it to this position prior to key removal from lock key cylinder 22, and (2) the vertical `size of slot a in FIG. 27 permits bell crank y25 to move from unlocked position K2 to locked position K1 without movement of lugv 22a from neutral or unactuated position KN and without key actuation of the tumblers of lock key cylinder 22. Now, the lock is in the locked position L and it is impossible to unlatch the lock and open the door by the outside handle 30. If the outside handle 30 is swung outwardly in FIGS. 1, 13 and 25 from its unactuated position OUA to its actuated position OA so as to move outside handle link 32 upwardly from the Vsolid line to the dot-dash line position in FIG. 16, pivot 188 will merely travel between the solid line and dot-dash line position in FIG. 16 in slot 176a but will not cause disengagement of cams 153, 155 and 156b from between the teeth of ratchet 146 so as to move it from the latched or unactuated position UA to the unlatched or actuated position A to permit door opening. After inside handle 26 has been manually actuated to move lever 194 from solid line position IUA to dot-dash line position IL in FIG. 17 to lock the door and then inside handle 26 is released, spring 27 in FIG. l, pushing against arm 26a, will return handle 26 in a counterclockwise direction to the neutral position IUA and lever 194 to its solid line neutral position IUA in FIG. 17.

Lock also has features to prevent unauthorized entry of the automobile by an intruder through the unlocked door if the car occupant quickly manipulates the inside handle 26. The occupant may be safe even if the intruder has had time to move the outside handle 30 to the fully actuated position OA, has withdrawn cams 153, and 156b from the latching or unactuated position UA between adjacent teeth of ratchet 146 to unlatching or actuated position A, and the rotor 120 has rotated 1A of a rotation counterclockwise in FIG. 24 to partially open the door to the safety position with the rotor 120 held between the first and second teeth from the right in FIG. 24 on striker 118. If the occupant grabs the nside handle 26 and swings it clockwise in FIG. 1 to the locked position IL before rotor 1211 has left the safety position, this movement of handle 26 will swing lever 194 clockwise to the dot-dash line position IL in FIG. 17 to lock the door by having arm 194C push upwardly lock slide by arm engagement with shoulder 165k, and by swinging locking lever 154 from unlocked position UL in FIG. 14 to locked position L in FIG. 16. This movement of lever 154 causes control link 184 to lower pivot 188 to break the toggle formed by toggle links 176 and by moving them to the solid line position of FIG. 16 so as to break the operative connection formed by the rigid toggle links 176 and 180 in FIG. 14 between outside handle 30 and latching cams 153, 155 and 156b. Then, springs 161, 163 and 162 will rotate lifting cams 153, 155 and 1156b counterclockwise to the solid line or unactuated position UA in FIG. 16 to snap the faces 153r, 155r and 1561 of these cams into latching engagement between adjacent teeth of and with a tooth of ratchet 146. 'Ibis locking action will automatically take place independently of the position of outside handle 30; and once the door is locked, the outside handle 30 may be freely moved between unactuated and actuated positions OUA and OA without opening the door. Note that the car occupant can lhold the door closed and lock the door by grasping only one inside handle 26, by both hands if necessary; and need not hold the door closed by grasping the handle with one hand while trying to actuate a separate inside lock button with the other.

Door 14 may also be locked from outside the automobile by the use of a key in the lock key cylinder 22. When the proper key is inserted in the lock 22 in FIGS. 25 and 26 and is rotated counterclockwise in FIGS. 1 and 13, the tumbler actuated lug 22a of lthe lock cylinder 22 will rotate clockwise in FIG. 27 from position KN to position K1 to lift link 24 from the unlocked, dot-dash line position K2 in FIG. 26 to the actuated locking, solid line position K1 in FIG. 26 to move the component parts of -the lock from the solid line, unlocked position UL in FIG. 14 to the solid line, locked position L in FIG. 16 to lock the door. Then, pivot 188 will be pulled down-
