Definitions

  • the present invention relates to a multi-point lock of the type described in the introduction to the claim.
  • Such multi-point locks are known to have the unlocking and locking movements controlled by equally large, but oppositely acting handle motions from a neutral position which is, normally, horizontal.
  • EP-A-0021820 discloses a multi-point lock by which the handle is turned for unlocking in one direction through an angle of 30° and in the opposite direction for locking through an angle of 90°. This dead lock position is released by a key- mechanism.
  • the object of the invention is to provide a lock of the said type where the optimum angle at the moment of unlocking (26°) is obtained without the handle rotation for overcoming the locking forces especially during the last movement of the locking means becoming too small in order to cause a high attraction. This is obtained according to the invention by the design specified in the claim.
  • the multi-point lock shown on the drawing comprises a lock casing 11, not specified further, which is designed for insertion in a door leaf.
  • the lock casing 11 contains a main guide - rotary part 1 - which can turn on an axle 20 at right angles to the plane of the drawing.
  • the rotary part 1 comprises two guide pins 21, 31 of which pin 21 is projecting into a first recess 23 of a main driver 2 which is vertically to and fro movable perpendicular to axle 20 which is extending through a second recess 27 in main driver 2.
  • the dimensions of this recess are larger than that of axle 20 in order to allow linear movement of driver 2 perpendicular to axle 20. This is clearly shown in the drawing.
  • the other guide pin 31 of rotary part 1 interacts with a recess 33 of a latch lever 4 that can be turned on said axle 20 and which is connected to a latch bolt 5 projecting from the lock casing 11 such that by turning the latch lever 4 the latch bolt 5 can be drawn into the lock casing 11 counterac- tiong the force of a spring 6.
  • the lock comprises a draw bar drive 3 which can be turned on another axle 30 at right angles to the plane of the drawing.
  • the draw bar drive 3 is provided with a pin 29 projecting into a hole 28 of the main driver 2 provided with a third recess 26 allowing its linear movement in respect to axle 30.
  • the arrangement of these parts (especially shown in Fig. 6) is so chosen that by turning the rotary part 1 the main driver 2 is moved linearly effected by the interaction of guide pin 21 and the periphery of recess 23.
  • the linear movement of the main driver 2 causes a rotation of draw bar drive 3 since pin 29 of bar drive 3 engages hole 28 of main driver 2.
  • the draw bar drive 3 has a serration engaging a draw bar 7 which reciprocates when the draw bar drive 3 is turned.
  • axle 20 of rotary part 1 is provided with a handle (not shown) for operating the lock.
  • the rotary part 1 is biased by a main spring 10 which tends to hold rotary part 1 in the neutral position shown in Figs. 2 and 4.
  • the lock is unlocked by turning rotary part 1 through 26° as shown in Fig. 3. This turn will cause guide pin 21 of the rotary part 1 to come into contact with the upper portion of the peripheral edge 24 of recess 23 and forces main driver 2 upwards.
  • the pin 29 of draw bar drive 3 engaging hole 28 of the main driver 2 then causes the draw bar drive 3 to turn clockwise so that the draw bar 7 is moved upwards.
  • the other guide pin 31 of rotary part 1 will at the same time engage recess 33 of latch lever 4 and turn it clockwise.
  • the latch bolt 5 is thereby drawn into the lock casing 11 against the effect of spring 6 so that the lock is unlocked.
  • main spring 10 will move rotary part 1 to the neutral position as shown in Fig. 4, and spring 6 will force latch bolt 5 outwards.
  • the recess 23 of the main driver 2 comprises sufficient space such that rotary part 1 can turn back in the neutral position without carrying the main driver 2 downwards.
  • the latch bolt 5 can be drawn in again by the rotary part 1 being turned through 26° (Fig. 3).
  • the guide pin 21 on the rotary part 1 will then only be shifted ineffectively in the recess 23 of the main driver 2.
  • Locking is effected by turning rotary part 1 through 45° starting from the neutral position in the opposite direction (Fig. 5). During this turn guide pin 21 comes in contact with the lower portion 25 of the periphery of recess 23 thereby carrying main driver 2 downwards. This downward movement is transmitted to the draw bar 7 via draw bar drive 3 pin 29 of which engages the hole 28 of main driver 2.
  • recess 23 of the main driver 2 is designed so that rotary part 1 can turn back in the neutral position without carrying the main driver upwards.
  • Fig. 7 is a graphic representation of the relation between the movement of draw bar 7 and the turn of the rotary part 1 during locking.
  • the attraction itself will take place when the draw bar has moved through 64% of the total movement.

  1. Mehrfachschloß mit einer Zugstange (7), die zwischen einer Verschlußposition (sh. Fig. 5) und einer Offenposition (sh. Fig. 3) durch Drehung eines Zugstangenantriebs (3) hin- und herbewegt werden kann, und einem Handgriff zum Betätigen des Schlosses, dadurch gekennzeichnet, daß ein Drehteil (1), das mittels des Handgriffes um eine Achse (20) gedreht werden kann, einen Führungsstift (21) aufweist, der in eine Aussparung (23) eines linear bewegbaren Hauptmitnehmers (2) eingreift, so daß eine Drehung des Drehteils (1) ein Hin- und Herbewegen des Hauptmitnehmers (2) bewirkt, der mit einer Mitnehmerbohrung (28) versehen ist, in welche ein Stift (29) eingreift, der auf dem Zugstangenantrieb (3) angebracht ist, so daß die Hin- und Herbewegung des Hauptmitnehmers (2) eine Drehung des Zugstangenantriebs (3) bewirkt, wobei die Aussparung (23) des Hauptmitnehmers (2) so bemessen ist, daß eine Drehung des Drehteils (1) um einen vorbestimmten Winkel (45°) von einer neutralen Position den Hauptmitnehmer in eine extreme Position (sh. Fig. 5) bewegt und eine Drehung des Drehteils (1) um einen anderen vorbestimmten Winkel (26°), der erheblich kleiner als der erstgenannte vorbestimmte Winkel ist, von der neutralen Position in die andere Richtung den Hauptmitnehmer (2) in die entgegengesetzte extreme Position (sh. Fig. 3) bewegt.
