First Claim
Patent Images
1. A fastener comprising:
- a first integrally formed clamp including,a base portion having a female receptacle configured to receive a reciprocal male member and to secure a button portion of the male member in a snap fit engagement with an arcuate wall of the female receptacle,the first arcuate arm pivotally coupled at a proximal end with the base portion by a living hinge, and having at least one elevated ridge at a distal end,the second arcuate arm coupled at a proximal end with the base portion in a cantilevered configuration, and having at least one elevated ridge at a distal end, the at least one elevated ridge of the second arcuate arm configured to enable an interlocking interaction with the at least one elevated ridge of the first arcuate arm;
a second integrally formed clamp including,a base portion having a projecting male member, the male member having a first portion proximate the base portion that is narrower than a distal second portion and also having a cylindrical button portion extending distally from the second portion,the first arcuate arm pivotally coupled at a proximal end with the base portion by a living hinge, and having at least one elevated ridge at a distal end,the second arcuate arm coupled at a proximal end with the base portion in a cantilevered configuration, and having at least one elevated ridge at a distal end, the at least one elevated ridge of the second arcuate arm configured to enable an interlocking interaction with the at least one elevated ridge of the first arcuate arm, the first and second arcuate arms curving relatively inward toward one another; and
a rotatable interconnection coupling the female receptacle of the first clamp to the male member of the second clamp wherein the first clamp can rotate 360 degrees relative to the second clamp.

Abstract
A fastener for joining two pieces of rebar together in a rebar grid used to reinforce subsequently poured concrete is described. The fasteners include two clamp pieces that in certain embodiments completely wrap around a piece of rebar and are tightly secured thereto. Further, each clamp piece can swivel or rotate up to 360 degrees relative to the other clamp piece such that two rebar pieces intersecting at any angle can be coupled together.
