AUXETIC LOCKING PIN

摘要

An auxetic locking structure can be used as a mechanism for securing two or more members in an assembly or other system. The locking structure has void patterns on its exterior surface which permit the locking structure to reduce its outer diameter upon loading in an axial direction. Once the structure has been sufficiently loaded and the diameter has been sufficiently reduced, the locking structure may be positioned within a bore of an article, the axial load is then reduced, thus causing the locking structure to expand and engage the bore of the article. The locking structure and article are now secured to one another creating an improved assembly.

1. A hollow pin comprising:
a hollow body having an outside surface, a thickness, a length, an end, and an axially extending internal bore; and a void structure located on the outside surface of the hollow body, the void structure extends through the thickness of the hollow body, the void structure provides for lateral contraction under an axial load.
