Abstract
Structure for connecting two members together, each including parallel, spaced apart, oppositely disposed, opposed surfaces having a cross section including a short straight portion adjacent one edge thereof, a longer obliquely extending portion extending from the other edge thereof and merging with an arcuate connecting portion which intersects the shorter straight portion, which surfaces are complementary and arranged to be in engagement with the members assembled. In one modification of the invention, the oblique portion of the surface cross section starts prior to the plane of the short straight line portion of the cross section and crosses it prior to merging with the connecting portion of the cross section. In another modification, the cross section of the surfaces of one member is formed with short straight portions at both edges of the surfaces with obliquely extending portions extending both ways from the center of the surface terminating in separate arcuate portions intersecting the short straight portions of the cross section. The connecting structure may be utilized to implement fasteners similar to nuts and bolts, may be utilized to secure a plurality of annular or pol…
