Abstract
A keysafe has tumblers which are set by a key-like programmer and has combination wheels which, when correctly set, have slots which receive the set tumblers. Thus, there is a unique combination for each programmer. In order to reset the combination wheels to their beginning, reference position, a slot is provided in each combination wheel, together with a lock bar which can enter the slot when the combination wheels are in the reference position. This lock bar is actuated to permit the programmer to be withdrawn.
Claims20
A keysafe comprising:
- a body, a compartment in said body, said compartment having an accessible and an inaccessible position;
- said body having programmer-receiving means for receiving a programmer, a programmer configured to be received by said programmer-receiving means;
- at least one combination wheel, said combination wheel being movable from a reference position to at least one other position, said combination wheel being associated with said programmer-receiving means so that said programmer can set said programmer-receiving means in a unique position and said combination wheel has a corresponding unique position, said programmer-receiving means being connected to said compartment so that when both said programmer-receiving means and said combination wheel are in their corresponding unique positions, said compartment can be moved from its inaccessible to its accessible position and when either of said programmer-receiving means and said combination wheel is away from said corresponding unique positions, said compartment cannot be moved from its inaccessible position;
- and
- means interconnecting said programmer-receiving means and said combination wheel for requiring positioning of said combination wheel in the reference position to permit withdrawal of said programmer from said programmer-receiving means.
A keysafe comprising:
- a lock body;
- a lock cylinder in said lock body, said lock cylinder being configured to receive a programmer, a plurality of tumblers in sid lock cylinder;
- a programmer configured to be inserted in said lock cylinder and to uniquely position each of said tumblers with respect to said lock cylinder in accordance with the unique shape of said programmer, said lock cylinder being rotatable in said lock body;
- a plurlaity of combination wheels rotatably mounted in said lock body and cooperating with said tumblers so that each said combination wheel has a unique position corresponding to a unique position of an associated tumbler so that when said combination wheels are aeach moved to their unique position corresponding to the unique tumbler position defined by said programmer, acces to said keysafe is achieved, each of said combination wheels having a reference position;
- means interengaging said lock cylinder and said combination wheels for permitting withdrawal of said programmer only when all said combination wheels are in the reference position.
A keysafe resetting mechanism for a keysafe having a programmer to individually set each of a plurality of tumblers in a lock cylinder and having a plurality of combination wheels settable to positions corresponding to the tumbler positions to permit access to a controlled space, comprising:
- a stop on each said combination wheel;
- engagement means for positioning with respect to said stops on said combination wheels;
- and
- means interconnecting said lock cylinder and said combination wheels for permitting withdrawal of said programmer only when said stops are against said engagement means with said combination wheels in a reference position.
