ABSTRACT:
A protective cover system for use in connection with guiding paths of machine tools including a plurality of overlapping cover plates telescopically moved into and out of each other while each cover plate at its front end face rests on the guiding path and at the rear end rests on the next segmental cover plate. Between the individual cover plates there are arranged energy storing means the return force of which is zero in the intermediate position of said energy storing means whereas the return force of said energy storing means is at its maximum in the fully pulled-out or pushed-in position of said cover plates. Each energy storing means includes a cylinder with an inserted elastic body and a piston. Between the cylinders and the piston at least one cam segment is provided. Relative movement between the cylinder and the pertaining cam segment is brought about by fork-shaped rods linked with the arms of said fork-shaped rods to the front end faces of the cover plates.
