ABSTRACT:
The invention is concerned with case catches (FIG. 4) comprising a claw 40 which can be driven by a crank mechanism through a finger plate 12 so as to retract the claw towards the finger plate and draw two parts of the case together. The mechanism includes an intermediate plate 22 which is journalled for rotation within the thickness of the cover plate 10 and is trapped between the parts which are arranged to turn with the finger plate 12 (14,16,18,20) on one side, and the face plate 24 on the other side. The assembly is held together by the rivets 28, 30 and freedom for rotation is maintained when the riveting step is completed, despite the part 32 being of the same thickness of the part 10 and hence liable to be trapped between the rotating assembly on the one side and the plate 24 on the other side, by the provision of a swaged annular rib 32.
