INTERENGAGING PARTS

摘要

A slidable arrangement comprises two parts having interengaging elongate formations. The elongate formation of one of the parts protrudes from the rest of that part. The elongate formation of the other of the said parts comprises a recess which receives and conforms to the protruding formation. The dimensions and the material are such that upon assembly of the arrangement, the protruding formation can be held over the recess, in alignment therewith, and snapped into the recess. After that the two parts are held together by the interengaging formations but can be slid relative to one another.
