Abstract
Abstract A method for molding a wire insert in the body of a plastic article to reinforce a bolt-receiving opening. The wire insert is formed of a wire coil in which each convolution of the coil is in contact with its neighboring convolution. The coil has openings between adjacent convolutions to permit liquid plastic to flow between the convolutions as the article is being molded so that the coil is embedded within the plastic.

Claim 1
Independent Claim
115 words
A combination comprising: a body formed of a molded plastic material, said body having an opening formed therein, an insert molded in said body, said insert comprising a wire member formed into a coil having a plurality of convolutions each convolution having a diameter greater than the diameter of the body opening and being embedded in the body such that each convolution is disposed about said opening, each convolution being in contact with its neighboring convolution, and a fastener being disposed in the body opening, the fastener having a head engaged with one end of the coil, and means carried on the opposite end of the fastener for engaging the opposite end of the coil.
