Locking device for the driver's cab doors of building machines

摘要

The device for locking the door leaf in the open-door end position on the side wall of the driver's cab consists of a locking lug arranged in a shell open to the outside of the side wall and of a locking hook which is arranged in a countersunk shell open to the outside of the door leaf and which is adjustable from a position projecting out of the countersunk shell and engaging into the locking lug into a countersunk position pivoted into the countersunk shell. To release the locking device both from the inside of the door leaf and from the inside of the side wall, the locking hook is connected pivotably to a pivoting lever pointing to the inside of the door leaf, and on the shell containing the locking lug is arranged a lever which points to the inside of the side wall and which is adjustable out of a position releasing the locking lug for the engagement of the locking hook into a disengaged position, in which the unlocking lever butts against the locking hook and presses the latter out of the locking lug.
