An attachment device and assembly for effecting connection and disconnection between component parts in a simple but reliable manner. A first structure includes first and second substantially parallel spaced apart plates, a conically-shaped, conically threaded member having a given cone angle attaching the first structure to a second structure which operatively abuts the first structure. Each plate has an aperture formed in it, the apertures being larger than the cross-sectional area of the threaded member portions being received thereby, and the second structure having a surface portion operatively abutted by the threaded member so that forces are applied tending to push the surface portion and aperture edges apart. The angle formed between a line tangent to the aperture edges and a line in the plane of the surface portion is equal to the cone angle of the threaded member. |
