Abstract
The invention relates to an improved device for opening a lock and a means for actuating the device. The device is characterized by a moving plunger or rotating wheel which is provided with slots which mesh with at least two rocking tumblers which engage the slots when they are biased by a reference card and thus prevent movement of the plunger or wheel. The rocking components can be disengaged from the slots when they in turn are biased by the proper keycard, thereby freeing the plunger or wheel and allowing operation of the mechanism of the lock.
Claims12
An improved device which can be adapted to an existing lock to allow the actuation thereof, the device being characterized by the fact that it consists of a movable plunger provided with slots which mesh with at least two rocking components meant to engage in the said slots when they are biased by insertion into this device of a notched reference component to prevent movement of said plunger, said rocking components being adapted to be disengaged from said slots and freeing said plunger by the insertion into this device of a second notched component identical to said reference component, to permit direct actuation of the mechanism of the lock.
A device as claimed in 1, in which said plunger is operatively engaged with the bolting mechanism of the lock, so as to allow actuation of the bolt.
A locking device in a door for use in cooperation with the locking mechanism of the door, said locking mechanism including a door handle, and said device comprising:
- moving means moveably mounted within said door and operatively associated with the door handle of said locking mechanism for movement therewith upon actuation of the handle in a direction to open the door;
- a plurality of rocking components pivotally mounted within said door and pivotally settable to an operative position in which the component blocks movement of the moving means and an inoperative non-blocking position;
- a reference means for biasing said rocking components to said operative position;
- a key means for biasing said rocking components to said inoperative position against the bias of said reference means;
- said rocking components and said moving means having cooperating means for engaging each other when at least one of said rocking components is biased by said reference means to its operative position so that movement of the moving means and actuation of the door handle of the locking mechanism is prevented and the movement of said moving means and actuation of said door handle is permitted when said rocking component is biased by said key means to said inoperative position.
A locking device adapted for use in a door for use in cooperation with the locking mechanism of the door, said locking mechanism including a door handle and said device comprising:
- means adapted to be moveably mounted within said door and operatively connected to the door handle of said locking mechanism for movement therewith upon actuation of the door handle in a direction to open the door;
- a plurality of rocking components adapted to be pivotally mounted within said door and pivotally settable to an operative position to block movement of the moving means and an inoperative non-blocking position;
- reference means adapted to bias said rocking components to said operative position;
- key means adapted to bias said rocking components to said inoperative position against the bias of said reference means;
- said rocking components and said moving means having cooperating means adapted to engage each other when at least one of said rocking components is biased by said reference means to its operative position so that movement of the moving means and actuation of the door handle of the locking mechanism is prevented and the movement of said moving means is permitted when said rocking components are biased by said key means to said inoperative position.
A locking device kit having component parts capable of being assembled for use in cooperation with the locking mechanism of a door said locking mechanism including a door handle, and said kit comprising the combination of:
- means adapted to be moveably mounted within said door and operatively connected to the door handle of said locking mechanism for movement therewith upon actuation of the door handle in a direction to open the door;
- a plurality of rocking components adapted to be pivotally mounted within said door and pivotally settable to an operative position to block movement of the moving means and an inoperative non-blocking position;
- reference means adapted to bias said rocking components to said operative position;
- key means adapted to bias said rocking components to said inoperative position against the bias of said reference means;
- said rocking components and said moving means having cooperating means adapted to engage each other when at least one of said rocking components is biased by said reference means to its operative position so that movement of the moving means and actuation of the door handle of the locking mechanism is prevented and the movement of said moving means is permitted when said rocking components are biased by said key means to said inoperative position.
A locking device in a door for use in cooperation with the locking mechanism of a door, said locking mechanism including a door handle, a lockable bolt, a means for unlocking said bolt, said device comprising:
- moving means moveably mounted within said door;
- means for actuation of said moving means operatively connected to said moving means;
- said moving means operatively associated with the means for unlocking for movement therewith upon actuation of said means for actuation in a direction to unlock the bolt;
- a plurality of rocking components pivotally mounted within said door and pivotally settable to an operative position in which the component blocks movement of the moving means and an inoperative non-blocking position;
- a reference means for biasing said rocking components to said operative position;
- a key means for biasing said rocking components to said inoperative position against the bias of said reference means;
- said rocking components and said moving means having cooperating means for engaging each other when at least one of said rocking components is biased by said reference means to its operative position so that movement of the moving means and actuation of means for unlocking the bolt of the locking mechanism is prevented and the movement of said moving means and actuation of said means for unlocking the bolt is permitted when said rocking component is biased by said key means to said inoperative position.
