| Abstract: |
A fastener system for adhesively coupling non-threaded components comprises, in combination a rigid bolt. The bolt has a head externally. The bolt has a shaft internally. The head has a generally hemispherical exterior end with a cental axis. The head also has a generally planar interior end. The head further has a top and a bottom. The shaft is in a generally cylindrical shape with a central axis. The fastener system also comprises a nut. The nut has a generally hemispherical exterior end. The nut has a generally planar interior end. The nut further having a top and a bottom. The exterior end of the nut has a radially circular flat region. A recess is provided in the circular flat region of the exterior end. The recess is adapted to receive the shaft. An adhesive provides a secure coupling between the nut and bolt.

First Claim:
Show all 20 claims |
What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows:
1. A plastic fastener system for adhesively coupling non-threaded components comprising, in combination:
- a rigid plastic bolt having an integrally fabricated head externally and shaft internally;
- the head having a generally hemispherical exterior end with a cental axis and a generally planar interior end, the head further having a top and a bottom, the exterior end having a radially circular flat region, the top and bottom, each having a flat gripping region axially lying in a plane parallel with each other and parallel with the axis;
- the shaft extending from the end of the head, the shaft having a generally smooth common cross sectional shape along it length with a central axis and with a flat face extending the length of the shaft, the flat face lying in a plane parallel with the axis and parallel with the flat gripping regions, the shaft terminates with a vertical free surface;
- a cap having a closed generally hemispherical exterior end and an open generally planar interior end, the cap further having a top and a bottom, the exterior end having a radially circular flat region, the top and bottom each having a flat gripping region axially lying in a plane parallel with each other and parallel with the axis, the cap further having a recess in the interior end, the recess being of a generally common cross sectional configuration along its length with a flat axial face receiving the shaft, the shaft and recess having the same cross sectional shape, the shaft and the cap and their faces being sized and shaped whereby when the shaft of the bolt is inserted into the recess of the nut, the various gripping regions of the nut and bolt and the flat portions of the shaft and aperture all lie in parallel planes;
- an adhesive lining the interior surface of the recess of the cap to provide a secure coupling between the cap and bolt when brought into contact with each other; and
- a fragile membrane in circular configuration with a periphery attached to the interior face of the cap adjacent to the recess and adapted to be positioned over the recess to prevent drying of the adhesive prior to use, the membrane further being adapted to be penetrated by the free surface of the shaft during operation and use to access the adhesive and couple the cap and bolt.
