Abstract
An injection molded fastener is provided for securing a preform to a foam substrate. The fastener includes a body having first and second ends with a head secured to the first end. A pilot section extends from the second end of the body, and includes a pointed end for penetrating and forming a hole in the preform and substrate. A plurality of angled barbs extend from the body for preventing removal of the fastener from the formed hole. The fastener is of sufficient strength to withstand a hammer blow and to penetrate the substrate when hammered. In a preferred embodiment, the fastener comprises a mineral filled nylon material.
Claims7
A fastener for securing a first member to a substrate member, comprising:
- a tapered body having first and second ends and opposing tapered flat sides;
- a head secured to said first end of said body;
- an extended pilot section extending from said second end of said body, and having a sharp pointed end for penetrating and forming a hole in the substrate member;
- a plurality of angled barbs extending from said body for preventing removal of the fastener from the formed hole, said barbs having distal ends cooperating to form a taper such that each successive distal end extends further away from the body than the previous distal end for improved gripping;
- and
- said fastener being a one-piece injection molded part.
A fastener for securing a fiberglass preform to a foam substrate, comprising:
- a tapered body having first and second ends and opposing tapered flat sides;
- a head secured to said first end of said body;
- an extended pilot section extending from said second end of said body, and having a sharp pointed end for penetrating and forming a hole in the fiberglass preform;
- a plurality of angled barbs extending from said body for preventing removal of the fastener from the formed hole, said barbs having distal ends cooperating to form a taper such that each successive distal end extends further away from the body than the previous distal end for improved gripping;
- and
- said fastener being a one-piece injection molded part.
An injection molded fastener for securing a fiberglass preform to a foam substrate, comprising:
- a tapered body having a body width and first and second ends, and having opposing tapered flat sides;
- a head secured to said first end of said body;
- an extended pilot section extending from said second end of said body, said pilot section having a pilot width narrower than said body width, and having a sharp pointed end for penetrating and forming a hole in the fiberglass preform;
- a plurality of angled barbs extending from said body for preventing removal of the fastener from the formed hole, said barbs having distal ends cooperating to form a taper such that each successive distal end extends further away from the body than the previous distal end for improved gripping;
- and
- said fastener comprising a one-piece injection molded mineral filled nylon material.
