US 4,583,671 A · Variable fit fastener attachment

Abstract

A variable fit fastener-applying attachment is disclosed which is particularly suited for use with a pair of locking vise type pliers. The attachment comprises a pair of first and second clamp members which are configured for respective mounting on the pliers jaws. The clamp members are configured for applying clamping pressure to a fastener assembly positioned therebetween such that the assembly is permanently applied to a piece of fabric, plastic, leather, or the like sheet material. In one embodiment of the invention, the variable fit nature of the attachment for mounting on different pairs of pliers having differently sized jaws is achieved by the provision of a pair of flexible gripping fins on each of the clamp members. In alternate embodiments, each clamp member is configured to provide resiliently flexible inward and outward movement of its sidewall portions to achieve the desired gripping engagement of the clamp members with the pliers jaws.

A variable fit fastener attachment for a pair of pliers having jaws, comprising:

a pair of first and second fastener clamp means each including a bottom wall, a front wall, and a pair of laterally spaced sidewalls which together define a generally rectangular cavity for receiving a respective one of the jaws of said pliers whereby said first and second clamp means are adapted for removable fitment to said pliers jaws in generally opposed relation for applying clamping pressure to an associated fastener assembly positioned therebetween,
each of said first and second clamp means including variable fit means to permit fitment of said clamp means to different pairs of pliers having differently sized jaws, said variable fit means of each said clamp means comprising a pair of flexible gripping fins extending integrally inwardly of said cavity from respective ones of said sidewalls generally from respective junction of said sidewalls and said bottom wall, each of said gripping fins decreasing in thickness from its respective one of said sidewalls to a free edge thereof.
