Patent ID: 8826625

Claim:
A fastener to secure rebar rods comprising: a substantially planar elongate and metallic main body having a first end portion, a second end portion, a third portion extending between the first end portion and the second end portion to define a medial portion, and a centerline substantially parallel to a length of the elongated main body; an opening having an opening length and an opening width and being formed through the first end portion so that the first end portion and the opening collectively define a head end having a width greater than a width of the medial portion, the opening length extending in the same direction as the length of the elongate main body and the opening width extending in a direction substantially orthogonal to the opening length, the opening length being less than the opening width; and at least two pairs of barbs, each pair of the at least two pairs of barbs depending from opposing lateral edges of the second end portion, each of the barbs of the at least two pairs of barbs having a lagging surface oriented oblique to the centerline and generally facing the head end, and each of the barbs of the at least two pairs positionally staggered along a length of the lateral edges as compared to another barb of the at least two pairs of barbs, the distance from a distal end of each barb of the at least two pairs of barbs extending to an opposing lateral edge defining a first barb end width and the distance from the distal end of each barb of the at least two pairs of barbs along one of the lateral edges to the distal end of each barb of the at least two pairs of barbs along the opposing lateral edge being a second barb end width, the first barb end width being less than the opening width and the second barb end width being greater than the opening width so that when the elongate main body is wrapped around the rebar rods and the second end portion is inserted through the opening and substantially aligned with the opening width the second end portion undulatingly inserts through the opening and so that when the elongate main body twistingly rotates about the centerline when the second end portion is inserted in the opening, the twist from the rotation produces an interference between the lagging surface and a length of a lateral edge of the opening to thereby retain the fastener around the rebar rods.
