Definitions

  • the invention relates to a mortise lock for mounting in a door or the like, as this is known by US-A-5 317 890 .
  • an actuation arm of a lock cylinder contacts the bolt in order to push it outwards, and a conveying element is used for pushing the bolt of the lock further outwards when this can no longer be done by an actuating arm.
  • a bore is provided in the bolt, extending square to its direction of movement.
  • a spring-biased pin is mounted in said bore. Said pin is provided with a second pin being transverse to the plane of the bolt, said second pin being guided by a slot made in a wall of the case. The bolt will be weakened by said slot and the other parts can only be of limited dimensions.
  • the object of the invention is to overcome this drawback by the provision of an alternative conveying element arrangement and so the invention provides a mortise lock for mounting in a door or the like, comprising a case in which a bolt is slidably received, an actuating arm being connected to an inner cylinder, mounted in an outer cylinder which is fixedly connected to said case, said actuating arm being rotatable with the help of a key, a part of said bolt, connected to the part thereof which can be located entirely outside of said lock, being fittingly received in said case and is provided with a recess having two side walls extending square to the longitudinal direction of the bolt, a conveying element being present for cooperating with said actuating arm, said conveying element, having almost the same thickness as said bolt, is slidably received in said recess in said bolt and is slidable together with said bolt and also transversely to its direction of movement and is pushed into the direction of the actuating arm by means of a spring, said conveying element being provided with a cavity in
  • said conveying element is provided with two pins being movable in two bent slots in said case for guiding said conveying element in relation to said case.
  • both lateral surfaces of the conveying element can be provided with one pin, said pins being offset in relation to one another, and each of the lateral walls of the case engaging them can be provided with a slot.
  • each slot has an oppositely bent portion into which a pin connected to the conveying element can be received when the bolt is pushed back into the case without using the key.
  • the bolt when the key is not used, the bolt can not be pushed into the case, since then the conveying element will provide a blocking of the bolt.
  • the drawing shows a mortise lock comprising a case 1 in which a bolt 2 is slidably received.
  • the case 1 is defined by the lateral walls 3, in which one of said walls can be connected to the transverse walls 4, so that a housing 5 is formed, to which the other lateral wall 3 can be fixed by means of screws.
  • the housing 5 is provided with a cross-plate 6, with which the lock can be fastened to a door or the like by means of screws.
  • the bolt 2 comprises a part 7 which is fittingly and slidingly received in the case 1, and a part 8 which can project outwards through the cross-plate 6.
  • a recess 9 in the part 7 of the bolt 2 holds a conveying element 10, which is slidable in the plane of the bolt 2 and transverse to its direction of movement V, see fig. 3 .
  • the conveying element 10 is spring-loaded by means of a compression spring 11.
  • a pin 13 is mounted on each lateral wall 12 of the conveying element 10 and each pin 13 is received in a slot 14 in one of the lateral walls 3 of the case 1.
  • the pins 13 are offset in relation to each other and obviously this also applies to the slots 14 in which they are located.
  • a slot 14 is provided with an oppositely bent part 15, in which the accompanying pin 13 will fall when an inwardly directed force is exerted on part 8 of the bolt 2 in particular.
  • the inward movement of the bolt 2 is limited by the slots 14, possibly in combination with the transverse wall 4 the of case 1, indicated in Figure 3 .
  • Holes 16 are present for fastening a possibly applicable metal work on the door.
  • An outer cylinder 17 is fixedly mounted in the case 1 and the inner cylinder 18 is rotatable within said outer cylinder 17. Rotation of the inner cylinder 18 takes place in a known way with the help of a key 19 providing for deblocking of the inner cylinder 18.
  • the key 19 can only be inserted in the inner cylinder 18 when the latter is in the position shown in Figure 2 .
  • the actuating arm 20 connected to it will at a given moment be received in a cavity 21 of the conveying element 10, as illustrated in Figure 3 .
  • the actuating arm 20 now starts acting on the conveying element 10, causing it to be pushed to the left, as seen in Figure 3 .
  • the conveying element 10 wil move upward, also due to the pins 13 received in the slots 14. With that, the spring 11 will be compressed.
  • the key 19 can be turned further, so that it will have been rotated across 360 degrees in total, and can then be taken out of the lock.
  • the actuating arm 20 can be rotated in the direction of the arrow R so that the arm will again be received in the cavity 21 of the conveying element 10. Conveying element 10 can then be moved upwards and to the right in order to pull the bolt 2 back into the case 1.
  • the lock can be designed in such a way, that the actuating arm can be rotated from both sides of the lock.
