Abstract: So as to mount a lock mechanism in a vehicle door at least partly of sandwich construction the door in the region of its outer side and end wall is provided with a compartment which from the end wall surface extends into the door and has one adjacent or complementary recessed portion in the outer side wall of the door. The lock mechanism is made in the form of a cassette which comprises at least two main parts, i.e. one lock house part and one adjoining control part. The cassette and the commpartment with the adjoining recessed portion are designed in such a way relative to each other that in the mounted position of the cassette the outside of its lock house part connects to and forms part of the door's outer end wall surface whereas the outside of its control part connects to and forms part of the door's outer side wall surface.

Abstract: A locking device for locking a spoked wheel carried in fork prongs comprises a housing mountable on one fork prong, and locking pin receiving means mountable on another fork prong. The housing is provided with a lock lever that is movable between a release position in which the wheel is free to rotate and a locked position in which the lock lever is in line with said locking pin receiving means. A locking pin is mounted within the lock lever and may be moved to protrude from one end of a bore extending through the lock lever. A lock member adapted to move the locking pin is provided adjacent the other end of said bore. The housing and the lock lever are so formed that the lock lever is retained in the locked position between the housing and the locking pin receiving means on removal of a support axle for the lock lever by force.
