Plastic fastener for spacing and supporting two plates

Claim 1

A fastener consisting of a one-piece molding of a plastic material, comprising: a first plate-like base portion for fastening a first member to be secured; an upright portion projecting from one surface of said first plate-like base portion; an L-shaped portion foldably united by a reduced thickness hinge portion to an intermediate portion of said upright portion and having a portion extending in the direction of said first plate-like base portion; and a second plate-like base portion extending from the other end of said L-shaped portion in the direction opposite to the direction in which said first plate-like base portion substantially extends from said upright portion, and substantially parallel to said first plate-like base portion, for fastening a second member to be secured; said second plate-like base portion being brought into contact with the free end of said upright portion when said second plate-like base portion and L-shaped portion are turned about said hinge portion in a direction away from said first plate-like base portion, said second plate-like base portion being brought into and held in contact with a surface of said upright portion on the side opposite said hinge portion due to elastic restoring force of said L-shaped portion when the point of contact between said second plate-like base portion and free end of said upright portion exceeds a point of intersection between said second plate-like base portion and a line normal to said second plate-like base portion and passing through said hinge portion.
