Fastener assembly
First Claim
1. A protector member for use with a push button type fastener, said fastener comprising an elongated shank having an outside surface and a first end terminating in a second end spaced from said first end , said elongated shank extending in a longitudinal axial direction;
- means defining an aperture extending inwardly from said second end of said elongated shank along the longitudinal axis of said elongated shank;
means defining an opening in said elongated shank that connects said aperture to the outside surface of said elongated shank; and
a retention member having first and second surface portions positioned in said opening;
said first surface portion of said retention member extending from the outside surface of said elongated shank, said elongated shank extending through an aperture formed in a panel member;
said protector member comprising a tubular shaped member having an internal diameter , the internal diameter of said tubular shaped member comprising a substantially continuous surface, said continuous surface not having shaped areas that coact with said retention member, said tubular shaped member being positioned about the elongated shank of said fastener adjacent to said first surface portion of said retention member; and
means for attaching said tubular member to said panel member.

Abstract
A fastener assembly for securing a first panel member to a second panel member in a spaced-apart relationship. The fastener comprises a tubular shank portion having first and second end portions, a cavity being formed in the shank portion. A first spring member is secured on the outside of the shank portion and has openings near the first end of the shank portion to enable steel ball members to protrude therefrom. Inside the shank portion cavity is a stepped pin member that is spring loaded and held in place by a combination of the shank portion spring ball retention feature and step angles formed on the pin member. A tubular shaped member is positioned adjacent the exterior surface of the ball members to ensure that the ball members do not extract themselves from their position within the cavity in case vibrations exceed time and frequency specifications.
