Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
164 words
An assembly of at least two rigid panels and a device for fixing the panels to a surface comprising at least a pair of rigid panels, each of the panels having contiguous adjacent lateral walls formed with at least two aligned openings therethrough and at least one of the walls including means to mount a fixing device on the lateral wall thereof, and a fixing device, said device comprising a base and means for fixing the base to a surface, an upright portion extending from the base, a hook member mounted for rotation on a shaft at one end on the upright portion and defining a hook at the other end thereof and an intermediate release projection, and means constantly urging the hook member away from the upright portion for engagement of the hook with one of the aligned openings in the lateral walls of the panel while the release projection extends through the other aligned openings to fix the panels to the surface.
Claim 2
Dependent Claim
