Definitions

  • ABSTRACT A paddle-type, key-controlled flush-mounted, springbiased bolt lock for swinging doors made primarily of metal stampings and having the key control in the shallower part of a two level recess and the handle in the deeper part of the recess with the non-pivoted end of the handle adjacent to the key control.
  • the key control includes a cam selectively movable into and out of the path of a member engageable with the bolt.
  • This invention relates to key-controlled locks and more particularly to paddle-type locks of the character mentioned as are commonly used on swinging doors of industrial cabinets.
  • the invention provides a new and improved paddletype, flush mountable, key-controlled, spring-biased, external actuated bolt, swinging door lock that can be quickly and easily installed, is rugged and durable in construction, comprises a relatively small number of parts which for the most part are metal stampings and therefore inexpensive to produce and assemble, and in which the key lock is located in an extension of the handle recess, preferably about one-half of the depth of the recess proper and at the non-pivoted end of the handle, and has a cam selectively movable into and out of the path of a member engageable with the bolt for selectively limiting retraction of the bolt.
  • FIG. 1 is a fragmentary front elevational view of a door and adjacent doorframe having a lock embodying the invention mounted in a recess in the door;
  • FIG. 2 is a longitudinal sectional view, with parts in elevation, approximately on line 2-2 of FIGS. 1 and 3;
  • FIG. 3 is a transverse sectional view, with parts in elevation, approximately on the line 3-3 of FIGS. 1 and 2;
  • FIG. 4 is a sectional view approximately on the line 4-4 of FIG. 2.
  • the lock of the present invention can be used on any swinging door, but is especially suited for use on doors of industrial-type cabinets, for example, on doors of merchandise, tool equipment and like cabinets or compartments of delivery and utility trucks, etc.
  • the preferred embodiment of the invention is the lock A illustrated in the drawings mounted in an opening or recess in a door B.
  • the door B may be of any suitable construction, and the edge opposite the look A is hinged to the door frame C of the compartment or vehicle body in any suitable manner.
  • the lock or latch A comprises, in general, a recessed mounting or body member D, a bolt housing 8 welded to the rear 'side of the mounting member D, a bolt member F slidable in the bolt housing and biased by a spring G to'a projected or latching position, and an actuating handle H pivoted in the two level recess R of the mounting member D and operable through a camtype bolt retracting trigger member T to retract the bolt member F against the bias of the spring G.
  • the bolt F is preferably made of a self-lubricating material such as molded glass-filled Nylon. It' may, however, be otherwise constructed.
  • the trigger member T projects through an elongated slot 10 in the bottom wall part 12 of the recess R in the mounting member D and into an elongated slot 14 in the bolt member F.
  • a striker plate 16 mounted on the doorframe C is provided with an opening 18 into which the bolt F extends when the door B is in closed position.
  • the projecting end of the bolt F is inclined as at 19 at an angle of to the length of the bolt so that the bolt can be retracted by its engagement with the striker plate as the door is closed without the necessity of the operative manipulating the handle T.
  • Other suitable angles of inclination may be employed on the end of the bolt, for example, 45".
  • the mounting or body member D comprises a rectangular pan-shaped sheet metal stamping member having a rectangular recess R opening into its front side and surrounded by a flange part 20.
  • the right and lefthand ends 22, 24, respectively, of the recess, as viewed in FIGS. 1 and 2, are of different depths.
  • the wall part 12 of the mounting member D forms the bottom of the deeper right-hand recess part 22 and the bottom wall part 26 forms the bottom or back of the shallower recess part 24.
  • the left and right-hand bottom or back wall parts 12, 26 of the recess R are connected by a vertical wall 28.
  • the recess has opposed side walls 30, 32 and opposed end walls 34, 36 which with the bottom wall parts 12, 26 and the step wall 28 define the two level shallow recess R.
  • the bolt housing E is a channel-shaped sheet metal stamping member having a web or bottom wall 40, a pair of opposed side walls 42, 44, a rear end wall 46 and flanges 48, 50 projecting outwardly from the side walls and welded to the bottom wall part 12 of the mounting member D.
  • the bolt housing E with the bottom wall part 12 of the mounting member provide a rectangular aperture within which the bolt F is slidably supported.
  • the bolt F is generally rectangular in cross-sectional shape corresponding essentially with that of the aperture within which it is slidably supported and the rear or left-hand end of the bolt, as viewed in FIG.
  • the handle H is a sheet metal stamping member comprising a generally rectangular substantially flat plate-like portion 70, a pair of inturned flanges 72, 74 along the sides of the portion 70 and which lie adjacent the longitudinal side walls 30, 32, respectively, of the recess R in the mounting member D.
  • the handle H is pivotally connected adjacent to its right-hand end to the mounting member D, that is, the end adjacent to the projecting end of the slide bolt by a hinge or pintle pin 76 extending through aligned openings in the side flanges 72, 74 of the handle member H and the side walls 30, 32 of the mounting member D.
  • One end of the pintle pin is headed and the other end is apertured for pivot pin.
  • the trigger member T has an extension or blade part 86 which extends through the elongated slot in the mounting member and into the slot 14 in the bolt.
  • the left-hand side of the blade 86 of the trigger member normally abuts against the left-hand end of the slot in the bolt.
  • the slot 14 in the bolt is extended to the right, as viewed in FIG. 2, so that the bolt may be retracted by engagement with the striker plate upon closing of the door to which the lock is mounted without moving the trigger member T.
  • the slot 14 may be only slightly longer than the blade of the trigger member.
  • the bolt actuating trigger T is a relatively narrow member rotatably supported on the pintle or pivot pin 76 which extends through an aperture therein.
  • the abutment surface 82 is on the front or forward end of the trigger member and the construction is such that as the handle member is rotated in a clockwise direction, as viewed in FIG.
  • the flange 80 thereof because of its engagement with the abutment 82 on the trigger member, rotates the trigger member in a clockwise direction about the pintle pin 76 and retracts the bolt
  • the bolt actuating trigger T is a substantial member but is relatively narrow referring to the distance or the length of the pintle pin 76 between the flanges 72, 74 of the handle member and is prevented from moving axially along the pintle pin 76 by engagement of the sides thereof with the sides of the slot 10 in the wall part 12 of the mounting member through which slot the blade part 86 of the trigger member extends at all times.
  • the right-hand end of the slot 10 preferably limits movement of the trigger member about the pintle pin 76 in a counterclockwise direction, as viewed in FIG.
  • the handle member H opposite the pivot pin 76 has a part 90 extending to the left beyond the side walls 72, 74 formed by an extension of the part 70 reversely bent to provide a underlying surface engageable by the fingers of an operator for the manual operation of the handle.
  • the door latch A includes a key-operated lock L which comprises a lock mounting cylinder 100, preferably of non-cylindrical form, mounted in a noncylindrical aperture such that it will not rotate therein in the rear wall part 26 forming the bottom of the shallow part 24 of the recess in the mounting member D.
  • the cylinder 100 is retained in the member D by a U- shaped member 103 located at and abutting the rear side of the bottom part 26 and the tines of which engage in slots 104 in opposite sides of the member 100.
  • the cylinder 100 supports a key-actuatable and rotatable lock component or member to the inner end of which a cam member 106 is riveted.
  • the projecting end of the cam member 106 can be selectably rotated by use of a key into and out of the path of the member 62 and in turn the bolt F.
  • the end of the cam 106 is behind the part 64 of the member 62 the bolt member F cannot be retracted.
  • the member 62 can be fixed to the bolt F, if desired, in which event it becomes a part of the bolt member.
  • the level of the bottom or back wall part 26 of the mounting member B is such that the lock L is located entirely behind or below the flange part 20 of the mounting member, but close enough to the top of the recess R so as to be readily accessible to an operative.
  • the cylinder can be threaded and secured in the wall part 26 by a nut thereon engageable with the rear or bottom side of the part 26 and the cam member 104 can be secured to the rotatable lock compartment by a threaded screw or by welding rather than being riveted thereto.
  • This construction facilitates removal of the key control L without removing the lock from a door or the like in which it might be mounted.
  • the size and strength of the respective parts are such that if the handle H is forceably moved in a clockwise direction, as viewed in FIG. 2, with the bolt F locked, that is, with the cam of the key control L preventing retraction of the bolt, the pintle pin 76 will bend before the bolt will retract thus making it impossible to force the lock, that is, retract the bolt, and open a door to which the latch is connected when the door is locked without use of akey.
  • the width of the trigger member T as viewed in FIG.
  • the width of the trigger member is not greater than about one-half the distance between the side walls 30, 32.
  • the latch is such that it can be readily mounted in right or left-hand doors or similar structure and be wholly flush therewith, that is, with none of the operating parts of the lock protruding forwardly of the mounting member. It is also noted that the key control L does not protrude beyond the rear or bottom of the lock proper.
  • One of the important features of the present lock is the fact that the key control L cannot be moved to locked position without the bolt F being fully projected or extended. If the bolt is not fully extended when the key is turned to lock position the cam 106 will force the member 62 and in turn the bolt to the right until the left-hand end of the slot 14 in the bolt is in engagement with the blade 86 of the trigger member T.
  • a flush mountable paddle-type lock of the character described comprising: a sheet metal mounting member having a peripheral planar flange part and a generally rectangularly-shaped recess opening into the front side the opposite end portions of which recess are of different depth, said recess being formed in part by two spaced parallel side wall parts connected by end wall parts and a first planar bottom wall part and a second planar bottom wall part spaced further from the front side of the mounting member than the first bottom wall part, said second bottom wall part having an elongated narrow slot adjacent to the end thereof spaced from said first bottom wall part and located midway between and parallel with said side wall parts of said recess, a channel-like sheet metal bolt housing having one end closed and the other end open secured to the rear side of said second bottom wall part lengthwise with respect to said elongated slot in said second bottom wall part with its open end adjacent to the said end wall part adjacent to said elongated slot, a bolt slidably supported in said bolt housing and having an end portion normally projecting therefrom through the
