Abstract

Lock device, including an electrically operable lock unit having at least one lock which by electrical influence can be moved between two different locations of extension in relation to the lock unit. The lock unit is arranged displacably within a surrounding casing, together with a manually and key operable lock mechanism. By influencing the lock mechanism, the electrically operable lock unit can be moved between two spaced positions in relation to the casing. In a first position, the lock unit is arranged adjacent to an edge portion of the casing, and in this position, the lock bolts can be moved by electrical influence to and from a position of engagement with a co-acting striking plate located adjacent to the casing. By influencing the manually operable lock mechanism, the electrically operable lock unit is moved to a second position, located at a greater distance from the co-acting strike plate in relation to the first position, and wherein in the second position the lock bolts can no longer engage with the striking plate.

Claims7

Dependent claims

A lock device comprising:

a manually and electrically operable lock unit;
an electrically powered means;
said lock unit including at least one lock bolt which can be moved between two different positions of extension in relation to said lock unit by said electrically powered means;
a housing adapted to receive said lock unit;
a manually operable adjacent lock mechanism adapted to operate said lock unit;
said lock unit being movable between two different positions in relation to said housing when said manually operable adjacent lock mechanism is manually operated;
said at least one lock bolt being movable from a first position relative to said lock unit by said electrically powered means only when said electrically powered means is operating;
said lock bolt being fixed against displacement relative to said lock unit when said electrically powered means is not operating;
said electrically operable lock unit including an electric motor having a rotary movement;
a first means for transforming said rotary movement into linear motion of said at least one lock bolt relative to said lock unit;
said first means for transforming including a mechanical transmission gear adapted to move said at least one lock bolt from an initial position to another position.
