Definitions

  • the invention relates to a lock mechanism equipped with a dead bolt and a latch bolt in accordance with the preamble of claim 1.
  • a door which is equipped with a lock body including a separate dead bolt to be used as a locking bolt and a latch bolt to be operated by a door handle, can be subject to the following malfunction.
  • a person coming in from outside the door does not know whether the door is locked he first tries to open the door using the door handle.
  • the draft seal of the door or possible warping thereof may allow the door to move somewhat on its hinges until the locking bolt acts to stop further opening of the door.
  • the door frame may prevent the door handle-operated latch bolt from returning to its normal locking position, whereby the entire force urging the door towards the open position is directed against the locking bolt.
  • it may be difficult to withdraw the locking bolt because this bolt is now withholding the sealing force pressing the locking bolt against the door frame.
  • An aim of the invention is to provide an improved lock mechanism which prevents the above-noted malfunction occurring yet which is uncomplicated in design and construction and has unimpaired functional security.
  • US-A-3990277 describes a mechanism having the features defined in the preamble of claim 1.
  • GB-A-2134170 describes a lock mechanism in which a handle mechanism can be disconnected from upper and lower bolts by operating a key.
  • the invention provides a lock mechanism as set out in claim 1.
  • the force transmission piece is plate-like and is supported to turn coaxially with said force transmission element.
  • the force transmission element may comprise a guiding member extending in the direction of a turning axis of the force transmission element and acting on a curved guiding surface provided on said force transmission piece so that the force transmission piece is positively guided in accordance with the movements of the force transmission element.
  • 1 indicates a lock body to be installed in a door or the like which is provided with a front plate 2, which includes an opening 2a for a dead bolt 3 and an opening 2b for a latch bolt 4.
  • the lock body 1 has a first operating axis 5, at which at least on the outer side of the door a key operated operating device (not shown), for instance a cylinder lock, can be installed for operating the dead bolt 3.
  • the lock body 1 includes a force transmission element 7 turnably supported on a pin 8 and having a bifurcated member 7a to receive a pin 18 turnable about the operating axis 5 to provide bolt-moving thrust to the element 7 and a guiding groove 7b to convey that thrust to a pin 9 for withdrawing the dead bolt 3.
  • the dead bolt 3 includes a plate-like member 3a, which is provided with the pin 9 and further stationary pins 14 and 15, a stop surface 13 and a guiding groove 10 including a stop surface 10a.
  • dead-locking of the dead bolt 3 is accomplished by means of several different members independent of each other so that the stop surface 10a cooperates with a pin 12 in the lock body 1, the stop surface 13 cooperates with the pin 8 in the lock body and additionally the pin 14 of the dead bolt cooperates with a stop surface 7c on the force transmission element 7.
  • the latch bolt 4 is provided with a pin 4a, which receives its guidance from a guiding groove 17 in the lock body.
  • the lock body also includes a second operating axis 6 at which a door handle (not shown), turning knob or the like, can be mounted to move the latch bolt 4 into its withdrawn position by means of a follower 11.
  • the lock body includes a plate-like force transmission piece 16 turnably supported on the pin 8 and having a cam 16a, which acts on the pin 4a in the latch bolt.
  • the follower 11 is in force transmitting engagement with the latch bolt 4 only through the cam 16a, which is shown in Figure 2 in a position where it can act to transmit force from the door handle to the latch bolt 4. It will be noted that in Figure 2 the dead bolt 3 is in its withdrawn position to allow opening of the door.
  • the force transmission piece 16 can be turned by means of the force transmission element 7 into the position shown in Figure 1, where the cam 16a remains outside the range of the turning movement of the follower 11. In this position force transmission from the operating axis 6 to the latch bolt 4 is impossible and the bolt 4 can be withdrawn only by first moving the dead bolt 3 from the operating axis 5 into its withdrawn position as shown in Figure 2.
  • the force transmission element 7 is provided with a protrusion 7d extending in the direction of its turning axis and including a guiding surface 7e, which acts on a guiding surface 16b arranged on the force transmission piece 16.
  • the force transmission piece 16 is provided with an opening 16c for the pin 12. Movement of the force transmission piece 16 into the position shown in Figure 1 to disconnect force transmission from the axis 6 can be accomplished in some other way, for instance by means of a spring. A positively guided operation, however, appears to provide a functionally more secure solution. Movement of the latch bolt 4 into its protruding position is conventionally accomplished by means of a spring (not shown).

Claims (5)

  1. Mécanisme de serrure, comportant un corps de serrure (1) supportant un pêne dormant (3) actionné par un moyen de transmission de force à partir d'un premier axe d'actionnement (5) au niveau duquel un dispositif activé par une clé peut être installé de manière à se déplacer entre une position verrouillée saillante et une position ouverte rétractée et un loquet (4) actionné au moyen d'un bec-de-cane (11) à partir d'un deuxième axe d'actionnement (6) au niveau duquel au moins une poignée rotative, un bouton ou similaire peuvent être installés, la transmission de force du bec-de-cane (11) au loquet (4) se faisant par l'intermédiaire d'une pièce de transmission de force (16) supportée mobile par rapport au corps de serrure (1), caractérisé en ce que le moyen de transmission de force pour le pène dormant (3) comprend un élément de transmission de force (7) mobile par rapport au premier axe d'actionnement (5) et arrangé en engagement de transmission de force avec la pièce de transmission de force (16) de sorte que le mouvement de l'élément de transmission de force (7) pour forcer le pène dormant (3) dans sa position verrouillée saillante déplace simultanément la pièce de transmission de force (16) dans une position dans laquelle la connexion de transmission de force du bec-de-cane (11) au loquet (4) requise pour déplacer ce dernier, ne puisse plus être établie.
  2. Mécanisme de serrure selon la revendication 1, caractérisé en ce que la pièce de transmission de force (16) est en forme de plaque et est supportée de manière à tourner autour du même axe (8) que l'élément de transmission de force (7).
  3. Mécanisme de serrure selon la revendication 1 ou la revendication 2, caractérisé en ce que les mouvements de la pièce de transmission de force (16) sont guidés positivement par l'élément de transmission de force (7).
  4. Mécanisme de serrure selon la revendication 3, caractérisé en ce que l'élément de transmission de force (7) fournit une surface de guidage (7e) s'étendant dans la direction d'un axe rotatif de l'élément de transmission de force (7) et agissant sur une surface de guidage courbe (16b) prévue sur la pièce de transmission de force (16).
  5. Mécanisme de serrure selon la revendication 4, caractérisé en ce que la surface de guidage (7e) est formée sur une saillie (7d) de l'élément de transmission (7).
