Rivet pin

A rivet for linking first and second members supported in spaced relationship with one another, said first and second members including openings therethrough of substantially cylindrical configuration, comprising:

• a. a substantially rigid shaft, said shaft having first and second end portions for occupying at least a part of each the openings through the first and second members;
• b. a first cap having an internal bore therethrough, said first end portion of said shaft being capable of extending into said bore of said first cap causing firctional engagement between said first cap and said first end portion of said shaft, said first cap having a tapered exterior surface for frictionally engaging the opening through the first member, said internal bore of first cap extending therethrough without connection to said tapered exterior surface of said first cap;
• said first cap further including a hollow member attached thereto and having a bore therethrough of substantially cylindrical configuration, said shaft frictionally engaging said bore of said hollow member, said hollow member including an external surface forming a portion between the first and second members, said hollow member including an enlargement of said substantially cylindrical bore therethrough, said enlargement having a wall frictionally engaging said second cap;
• c. a second cap having an internal bore therethrough, said second end portion of said shaft being capable of extending into said bore of said second cap causing frictional engagement between said second cap and said second end portion of said shaft, said second cap having a tapered exterior surface for frictionally engaging the opening through the second member, said internal bore of said second cap extending therethrough without connection to said tapered exterior surface of said first cap, said frictional engagement of said first and second caps with the first and second members and said frictional engagement of said bores of said first and second caps being of sufficient magnitude to fix said shaft between the first and second members, said first and second caps being constructed of relatively hard, rigid, material.
