Abstract:
1. A precise linear fastener system comprising: a collet member having a base end, a top end, an inner engaging surface, and an outer ribbed surface positioned about a central axis, said outer ribbed surface including a first non-helical circumferentially extending rib spaced apart and in a parallel plane with at least one additional non-helical circumferentially extending rib; a compression ring member having a base end, a front end, an inner ribbed surface having a first non-helical inwardly extending rib spaced apart and in a parallel plane with at least one additional non-helical radially inwardly extending rib, and an outer surface positioned about a central axis; said inner ribbed surface of said compression ring member being constructed and arranged for coaxial alignment and overlapping engagement with respect to said outer ribbed surface of said collet member, said compression ring member non-rotationally linearly traversable with respect to said outer ribbed surface of said collet member between a first release position and a second engaged position, wherein said engaged position results in said outer ribbed surface of said collet member and said inner ribbed surface of said compression ring compressing said collet member and tensilely loading said compression ring member to engage a shank member having an outer gripping surface whereby said collet member is clamped to the shank member without rotating said collet member, and wherein said release position results in expansion of said collet member thereby releasing the outer gripping surface of the shank member.
