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.
