Definitions

  • the invention relates to a door lock with a split nut nut according to the preamble of claim 1.
  • Latch locks in a simple embodiment are via door handles, which are arranged on the outside and inside of a door are operable.
  • the door handles or handles effect one Trigger nut a withdrawal of at least one lock latch.
  • Latch locks with two different functions on the Inside and outside have a split follower with an inner nut and an outer nut on which one Act on the lock latch.
  • Such latch locks are particularly used as panic locks where the door from the inside can be opened at any time while on the outside as a normal function, the pusher runs empty and only then pulls back the trap and a door opening is effected when a cylinder lock belonging to the latch lock is actuated first.
  • the outside handle is coupled to the lock latch, see above that the door is opened when the lever handle is depressed.
  • the cylinder lock can still be operated with an access control system be combined. It can on the latch lock a magnet can be arranged with which the connection between Handle and lock latch is manufactured.
  • the invention has for its object to provide a latch lock with a return spring arrangement, which ensures an actuation of the door handle with a normal effort and at the same time a safe return of the follower and door handle.
  • the basic idea of the invention is a reset arrangement with at least three return springs. These three return springs are arranged and designed such that at least always two return springs, maximum all three with one split Are engaged.
  • three return springs arranged in an arrangement one above the other.
  • Each The three return springs are particularly narrow around this arrangement to enable.
  • Fig. 1 is an example of a latch lock 2 with shared follower a self-locking lock with a Housing 11, a bolt 12, a latch 13 and one Auxiliary trap 14 shown, but only with regard to features which is related to the present invention stand. The other functions and mechanisms of action are evident from DE 44 07 244 C1.
  • the lock is a two-part trigger nut 3 and one key-operated lock cylinder 16 with a Locking lug 17 can be actuated.
  • the latch lock according to FIG. 1 can panic from the inside of the door at any time and be opened reliably. From the outside the lock can be locked with a key and, if authorized, via an external jack or an external one Door knob can be opened. The authorized opening with a key is by arranging a change 27 guaranteed.
  • the split trigger nut 3 with the inner nut 5 and the outer nut 7 is operatively connected to a reset arrangement 10.
  • This return arrangement 10 has three return springs 4, 6, 8 (see Fig. 2c, 3c, 4c, 5c) on the in Fig. 1 shown opening phase of the door and thus connected rest position of the follower 3 and the reset arrangement 10 arranged one behind the other in the plane of the drawing and are not recognizable individually.
  • the inner nut 5 has a lower driver 15 and one with the trap 13th engaged upper driver 18 and is non-rotatable with an inner pawl or an inside handle (not shown) connected.
  • the outer nut 7 is a Electromagnetically actuated clutch 20 with the inner nut 5 connected.
  • the clutch 20 consists of a spring-loaded Detent 22 and an armature 23 of an electromagnet 24 to operate the catch 22.
  • the coil 24 is energized and the armature 23 attracted so that the clutch 20 engages. If the electromagnet is not energized, then the inner nut is 5 the trigger nut 3 uncoupled from the outer nut 7.
  • the Trap 13 against the bias of a spring 21 by engagement of the driver 18 on a hook 19 of the trap 13 withdrawn (not shown.)
  • FIG. 2 to 5 is a first embodiment of the Reset arrangement 10 according to the invention shown. It includes three relatively narrow return springs arranged one above the other 4, 6, 8, which has an inside push rod 25 and an outside push rod 28 on the Act on inner nut 5 and outer nut 7.
  • the connection of the Return springs 4, 8 with the inside and outside Push rod 25, 28 and the connection of the push rods 25, 28 with the inner nut 5 and the outer nut 7 are strong represented schematically. It is non-positive Links.
  • Fig. 2 also shows a detent 22 as well those with an inside handle and not shown Outside handle non-rotatably connected square pins 30, 31.
  • 3a to 3c is a door handle actuation shown "inside", for example in a panic case.
  • Identical reference signs are used for the same features used.
  • the inner nut 5 was using an inner jack deferred, as well as from the position of the square pin 30 according to FIGS. 3 and 3b. especially the 3a illustrates the mode of operation of the additional ones Return spring 6, which acts as a middle return spring between the inner return spring 4 and the outer Return spring 8 is arranged and in the shown in Fig. 3a Position together with the inner return spring 4 resets the inner nut 5 via the inner push rod 25.
  • FIGS. 6 to 9 An alternative embodiment of an inventive Reset arrangement 10 is shown in FIGS. 6 to 9.
  • 6, 6a to 6c are the inner nut 5, the outer nut 7, inside and outside push rod 25, 28 and inner and outer return spring 4, 8 shown in the rest position.
  • the square pins 30, 31 illustrate that neither one inside and one outside jack (not shown) was pressed.
  • the inner nut 5 is actuated analogously to FIG. 3.
  • the non-actuated freewheel side, the outer nut 7 is from the outer return spring 8 held up, as well as from the Position of the outer square pin 31 in Fig. 7b emerges.
  • the additional return spring 26 acts according to FIG. 7a on the inner return spring 4 and moves the actuated Inner pawl back to its original position.
  • Fig. 8 shows the follower 3, the return springs 4, 8 and the additional return spring 26 when actuated “outside without authorization ", in which the inner nut 5 and the Outer nut 7 are disengaged, as from the position of the Detent 22 can be seen.
  • the Inner nut 5 which is also called panic nut, from the inner return spring 4 held up.
  • the additional Return spring 26 is the additional Return spring 26 on this.
  • FIG. 9 shows analogously to the first exemplary embodiment according to FIG Fig. 5 shows a handle follower "outside with authorization".
  • Stand with the clutch engaged according to the position of the detent 22 three springs, namely the inner return spring 4 and the outer return spring 8 and the one arranged behind it additional return spring 26 engaged and ensure that both the inner jack and the Outside jack are moved back to their rest position as soon as the outside jack is released.
  • the invention is not based on the illustrated embodiment and especially not on panic locks limited.
  • the invention can be used with all locks shared follower can be used advantageously.
