Definitions

  • the present invention relates to locking mechanisms. More particularly, though not exclusively, the invention seeks to provide an electromechanical locking mechanism which can be used in an electronically-controlled code-recognition lock for safes and the like security enclosures, which is mechanically simple and highly reliable in operation, and operable with minimal power consumption.
  • a locking mechanism comprising a bolt movable between locking and unlocking positions; a manually rotatable follower adapted to be coupled to the bolt for retracting the latter from its locking to its unlocking position; and an electromechanical actuator (solenoid) arranged for selectively disabling or enabling the coupling of the follower to the bolt such as to move the latter from its locking to its unlocking position.
  • a link bar is pivoted to the bolt and has a hooked tail portion which in one condition lies in the path of movement of an arm extending from the follower, so that turning the follower can withdraw the bolt.
  • the solenoid (which is located in the associated keep assembly) is actuated to drive a pin onto the opposite end of the link bar and thereby pivot its hooked end clear of the path of the follower; simultaneously the pin engages in the bolt to lock the same in the keep.
  • this mechanism in general works well a disadvantage is that the solenoid must move the link bar against a gravitational bias in order to decouple the follower from the bolt, therefore consuming considerable power, and it is geometrically unsuited to the location of the solenoid within the same lockcase as the follower and bolt.
  • it is essential that the command to the solenoid to lock and decouple the bolt is only given after the bolt has extended into the keep, otherwise the pin will obstruct such extension and leave the bolt and follower coupled.
  • the lock shown in the drawings is intended principally for use in locking the main boltwork of a safe or vault door, and its layout and dimensions are chosen so that the unit may be interchangeable with known keyless combination locks, such as that marketed by the present applicants under the designation 7L08.
  • It has a bolt 1 which can be extended and retracted from the case 2 and to which a drop-arm 3 is pivoted at 4.
  • the arm 3 has a laterally extended head 5 at its end opposite to its connection with the bolt, which in the normal locked condition of the mechanism illustrated in Figure 1 lies on the periphery of a rotatable disc 6, onto which it is drawn by a spring schematically indicated at 7. In this condition the head 5 faces a fixed abutment 8 in the lock case to resist forced retraction of the bolt 1.
  • the disc 6 is freely rotatable by hand through the agency of an external knob or handle (not shown), within limits set by a stop 9A, but is normally held lightly in the rest position shown in Figure 1 by means of a detent spring (not shown). It has a notch 10 in its periphery which, when the disc is-turned anti-clockwise (in the sense of the drawing) away from its rest position underlies the head 5 of the drop-arm, and into which the head is biased to engage by the spring 7 so as to establish a drive connection between the disc 6 and bolt 1. Normally, however, the head 5 is blocked from moving into full engagement with the notch 10 and free of the abutment 8 by the presence of the actuating member 11 of a bistable electromechanical actuator 12.
  • the remanence of the element 11A is sufficient to keep the actuating member in that position until an electrical pulse is sent through the coil 13 in the opposite direction, whereupon the induced polarity of the element 11A is reversed so that its end between the poles P1 and P2 now becomes a North, and it will be influenced oppositely by the permanent magnet poles to pivot the actuating member into the position in which it is shown in Figure 2, being its release position.
  • magnetising pulses are supplied to the coil 13 from an electronic control circuit (not shown) associated with a code-input or recognition device such as a numeric keypad, card- reader, biometric sensor or the like, so that the coil 13 is pulsed to move the actuating member out of its Figure 1 position and into its Figure 2 position only when a correct code or other indication of the user's authority to operate the lock has been entered.
  • a timing circuit may also be included to restrict possible operation of the actuator to its release position only to specified periods of the day.

Claims (5)

1. Mécanisme de v'errouillage comprenant un pêne (1) ou un autre élément de verrouillage de ce genre, mobile entre une position de verrouillage et une position de dé verrouillage; un élément (6) de commande, rotatif, apte à être accouplé à l'élément (1) de verrouillage en vue de tirer ce dernier en arrière à partir de sa position de verrouillage pour l'amener à sa position de dé verrouillage; et un élément (12) d'actionnement électromécanique, agencé en vue de créer ou de faire cesser sélectivement l'accouplement de l'élément (6) de commande et de l'élément (1) de verrouillage de façon à. déplacer ce dernier (1) de sa position de verrouillage à sa position de déverrouillage; mécanisme caractérisé en ce que l'élément de commande a la forme d'un disque (6) ou d'un secteur circulaire comportant. sur sa périphérie, une encoche (10) d'accouplement, et un bras (3) est articulé avec l'élément (1) de verrouillage ce bras comportant une tête (5) poussée pour se mettre en prise d'entraînement dans ladite encoche (10); en position de repos de l'élément (6) de commande, ladite tête (5) reposant sur la périphérie de l'élément (6) de commande, sans être en prise avec ladite encoche (10) alors que la rotation de l'élément (6) de commande, à partir de cette position, place l'encoche (10) dans une position de réception dp la tête (5); ledit élément (12) d'actionnement sert dans une première position à faire obstacle au déplacement dudit bras (3) de façon à en engager la tête (5) dans ladite encoche (10) lorsque l'élément (6) de commande est tourné, comme dit précédemment et sert dans une seconde position à libérer le bras (3) afin qu'il engage sa tête (5) dans ladite encoche (10) sous l'effet de ladite poussée lorsque l'élément (6) de commande est tourné comme dit précédemment; et le déplacement de retour de l'élément (6) de commande jusqu'à sa dite position de repos sert à éjecter ladite tête (5) de ladite encoche (10) pour que cette tête repose sur ladite périphérie comme indiqué précédemment.
