Definitions

  • the invention relates to a mortise lock provided with an inside handle and an outside handle, which has a slide guided parallel to the faceplate, which is pretensioned by means of a lock bit through a single locking tour with complete locking inference and is held in a tensioned position by means of a lock in such a way that he releases the bolt lock after releasing the lock by the lock bit.
  • European patent application EP 0 204 944 B1 also describes a latch panic lock which can also be used as a tubular frame lock and has an outer and an inner handle and a three-part nut.
  • the middle and the inner nut part have cooperating driver cams which enable these nut parts to be locked together.
  • an additional coupling rocker is required which keeps the outer nut part out of engagement with the middle or inner nut part.
  • the inner nut part can be rotated from the inside of the door while taking the middle nut part with it, the panic lever, switch bolt and tumbler plate of the slide bolt and the lock latch being retracted via further required lock parts.
  • the nut is divided into three; it can be seen that the nut parts lying one above the other because of the limited overall height can only be of a small thickness, so that they are relatively susceptible to wear.
  • the aforementioned castle furnishings also require a relatively large amount of construction work.
  • DE 44 07 244 C1 describes a self-locking lock with a two-piece follower, the nut parts of which can be coupled via an electrically actuated clutch.
  • an auxiliary latch is provided which, in cooperation with a catch blocking the lock bolt, prevents the rain from automatically closing when the door is open.
  • the lock can be operated either via the lever follower or the change lever actuated by the lock cylinder.
  • EP 0 575 701 A1 discloses a key-operated mortise lock with a one-piece follower, whereby only the latch, but not the latch, can be actuated via the follower.
  • the lock bolt and lock latch can be closed or closed.
  • EP 0 092 630 A1 relates to a mortise lock with a multi-point lock effected by means of a drive rod, the lock bolt which can be actuated by means of a key and an intermediate transmission being divided into two and the movement of the drive rod being controlled via a ramp arranged in the lock bolt.
  • Devices for achieving a switching function i.e. For the optional actuation of the lock only from the inside (panic function) or for simultaneous actuation from the inside or outside by key actuation are not provided in the aforementioned security door lock.
  • the object of the invention is to further develop a mortise lock in such a way that a reliable and less constructional switching function can be achieved with the mortise lock.
  • the panic and switchover function should thus be made possible in a narrow mortise lock, for example in a tubular frame lock, using only a two-part nut.
  • a pre-tensioned locking yoke is achieved by turning the key a quarter of a turn. The bolt is returned from its fully closed position to the fully closed position.
  • the locking mechanism for the bolt lock is to a certain extent armed ".
  • the beard of a locking cylinder can grasp the free end of a release lever which, when acted on in the opposite direction, now releases the lock, so that the slide is suddenly withdrawn from its associated spring and triggers the latch lock. It can be seen that in order to trigger the bolt lock, strictly speaking, it does not even require a one-turn locking, but only the unlocking of a lock, whereby less than a quarter turn of the key is required.
  • the lower change lever is automatically brought into a position by means of the pin arranged on the bolt, with which the change function can be triggered by means of the lock cylinder bit, ie the latch can be closed.
  • the change and panic function is thus integrated into a lock mechanism, in which the slide is pretensioned during the bolt return and the bolt lock can be triggered suddenly by briefly pressing the key.
  • the lower part which is present anyway for the changing function, is used according to the invention to achieve the switching function by the nut.
  • the mortise lock seen in strictness is a so-called single-turn "lock; the further closing tour characterized in feature d of claim 1 only has the task of loading the interchangeable lower part; it is not a closing tour with which a movement is exerted on the bolt.
  • a switch lever which can be pivoted into an undercut groove of the outer nut and which can be acted upon directly by the interchangeable lower part is mounted on the inner nut half (claim 5).
  • the two nut halves thus remain uncoupled; this means that the panic function is guaranteed while the lock cannot be operated using the outside handle.
  • the change-over lever is swung into the undercut groove of the outer nut half through the interchangeable lower part with the help of the second closing tour (the bolt is closed)
  • the lock latch can be operated either via the inside handle or the outside handle, whereby when the outside handle is actuated, the inside handle also pivots becomes.
  • the two nut halves are coupled together in this position.
  • a bearing pin of the switch lever connected to the inner nut half is used for this purpose, which protrudes axially into the area of the outer nut half, i.e. the bearing pin projects beyond the abutting surfaces of the inner and the outer nut half in the direction of the outer nut half, so that the switch lever can pivot into the undercut groove of the outer nut half (claim 3).
  • the aforementioned bearing pin of the switching lever is coaxially aligned on a arranged on the inner half of the nut, which acts on the interchangeable cam; the cam also serves to guide the inner half of the nut in the lock top.
  • the mortise lock generally designated 1
  • the slider denoted by 4 can be moved upwards in the plane of the image by means of the locking bit 12, so that its cam 26 can snap into the lock 9 of the locking lever 8 and be held there.
  • the bar 5 is shifted to the right in the image plane.
  • the locking lever 8 can be pivoted in such a way that the cam 26 leaves the lock 9 and the bolt lock is triggered, so that the position of the regulator 5 shown in FIG. 1 results.
  • the interchangeable lower part is designated, which interacts with the switching lever 18 mounted on the inner nut half of the lock nut 14.
  • the panic lever 13 is also indirectly supported in the lock nut 14.
  • With 11 the lock latch 6 actuating upper part is designated.
  • FIG. 2 shows the mortise lock 1 with the bolt 5 and the latch 6 locked, ie the closed position in which the lock must be able to be opened from the inside in the event of a panic.
  • the slide 4 ( Figure 1) is in the lower position; the interchangeable lower part 10 is also in the lower position and disengaged from the lock bit 12. Consequently, the changeover lever 18 is disengaged from the stop 21 of the interchangeable lower part 10.
  • the bolt 5 is actuated by the slide 4 and Lock latch 6 can be closed by actuation of the interchangeable upper part 14, actuation of the outer handle only causes the same to idle, because the nut halves (inner nut half 15, outer nut half 16), see FIGS. 9 and 10, are not locked together.
  • the representation according to FIG. 3 denotes the situation when the bolt 5 is closed, only the lock latch 6 being locked, i.e. by actuating the locking cylinder at one speed, the slide 4 is moved into its upper position and engages with its cam 26 in the lock 9. Due to the movement of the slide 5, the interchangeable lower part 10 has come into the engagement area of the locking bit 12. The stop 21 of the interchangeable lower part 10 is still out of engagement with the changeover lever 18. In this situation, the lock latch 6 can be actuated by the inside handle; the outside handle has no influence on the movement of the lock latch 6, because the nut halves 15, 16 are not locked together.
  • the interchangeable lower part 10 has been shifted upward in the image plane by the locking bit 12, so that the stop 21 of the interchangeable lower part 10 presses the changeover lever 18 into the undercut groove 17 (see FIG. 9) of the outer nut half 16.
  • the hook-like projection 23 on the switching lever 18 grips the undercut 24 of the groove 17, so that when the outer handle is actuated, both nut halves 15, 16 and the inner handle are carried along. So this is the representation of the toggle function; the above-described switchover function can be achieved by actuating the locking cylinder again in the sense of rotation clockwise in the image plane, so that, as described above, the lock bit 12 can lift the lower part 10.
  • a guide pin 22 is arranged on the outer nut half 10, which leads in a corresponding arcuate backdrop of the lock plate 2.
  • the inner nut half 15 has a cam 20 running coaxially with the bearing pin 19 of the switching lever 18, which cam is also guided in an arcuate backdrop of the lock cover 2, but on the other hand has the task of including the lock latch 6 in cooperation with the interchangeable upper part 11.
  • a bore 25 adapted to the bearing pin 19 is arranged in the switching lever 18.
  • FIG. 1 designates a spring which acts on the nut in the left-turning sense in the image plane; the spiral spring shown there can of course be replaced by differently designed spring elements (see positions 28 and 29 in FIGS. 9 and 10).
