Abstract
A bolt lock, especially for control-cabinet doors or similar doors or flaps. The lock comprises a flat-bar bolt that is mounted to move parallel to the edge of the door, preferably within the arc of swing of the door. Disposed on the flat-bar bolt is at least one locking section. A bolt holder is mounted on the frame of the door to receive and hold the locking section. An actuator is provided for longitudinal displacement of the flat-bar bolt between an unlocked and a locked position. To provide a more secure lock that cannot become stuck, there is provided that to form the locking section, at least a portion of a length of the flat-bar bolt is twisted about a longitudinal axis of the bolt such that the twisted portion is disposed at an angle to an orientation of the bolt and provides a locking surface. The bolt holder is provided with a catch that is disposed at the same angle relative to the bolt as is the locking surface, with the catch being adapted to engage over the locking surface.
