Abstract

A rebar clip is provided for joining a larger diameter rebar to a smaller diameter rebar transverse to the larger diameter rebar. In a first embodiment the clip includes diameter reducing tabs extending into upper arches of the clip for engagement with smaller diameter bars crossed on top of larger diameter bars. In a second embodiment the clip includes diameter reducing tabs extending into lower arches of the clip so that the clip may hold larger diameter bars on top of smaller diameter bars. A guide track for a clip applying gun is provided which allows for use with either version of clips and with clips of the same nominal diameter for joining equal size bars.

Claims

1. A rebar clip for joining a larger nominal diameter rebar and a smaller nominal diameter rebar crossed perpendicularly to each other, the clip comprising:

a clip body;

a lower pair of aligned partially circular lower lateral openings defined in the clip body and aligned in a first direction;

an upper pair of aligned partially circular upper lateral openings defined in the clip body transversely to the first direction;

wherein partially circular portions of both the lower pair of lateral openings and the upper pair of lateral openings are of the larger nominal diameter;

the clip body being downwardly open below both the lower and upper pairs of lateral openings so that the clip can be pressed downward over the crossed larger and smaller nominal diameter rebars; and

a pair of opposed diameter reducing tabs extending toward each other into the lower pair of lateral openings, so that the clip can hold the larger nominal diameter rebar in place above the smaller nominal diameter rebar.

2. The rebar clip of claim 1, wherein:

each pair of the diameter reducing tabs includes opposed obliquely upward facing concave corners for engaging the smaller nominal diameter rebar from below.

3. The rebar clip of claim 1, wherein:

the clip body includes two pairs of downwardly extending resilient legs; and

the lower pair of aligned partially circular lower lateral openings are defined by the two pairs of legs, each pair of legs defining a lower gap dimension smaller than the smaller nominal diameter.

4. The rebar clip of claim 1, wherein:

the clip body includes two pairs of downwardly extending resilient legs;

the lower pair of lateral openings are defined by the two pairs of legs, the legs having a leg thickness in the first direction; and

the tabs have a tab thickness in the first direction, the tab thickness being equal to the leg thickness.

5. The rebar clip of claim 1, wherein:

the clip body includes two pairs of downwardly extending resilient legs;

the lower pair of lateral openings are defined by the two pairs of legs, the legs having a leg thickness in the first direction; and

the tabs have a tab thickness in the first direction, the tab thickness being less than the leg thickness.

6. The rebar clip of claim 5, wherein:

the tabs are flush with an inside surface of their respective legs, the inside surfaces of the legs being those surfaces which face the other pair of legs.

7. A rebar clip for joining a larger diameter rebar to a smaller diameter rebar transverse to the larger diameter rebar, the rebar clip comprising:

a clip body defined along x, y and z orthogonal directions;

the clip body including first and second pairs of resilient legs extending in the z-direction and defining first and second lower arches aligned parallel to the x-direction;

the clip body including first and second pairs of resilient arms extending in the z-direction away from the legs, the arms defining first and second upper cradles aligned parallel to the x-direction;

the clip body including first and second bridges joining distal ends of the first pair of arms to distal ends of the second pair of arms, the bridges and the arms defining first and second upper arches aligned parallel to the y-direction;

the lower arches, the upper cradles and the upper arches each including curved portions of the larger diameter; and

pairs of diameter reducing tabs extending into either the lower arches or the upper arches for engaging the smaller diameter rebar;

wherein the diameter reducing tabs extend into the lower arches so that the clip can hold the larger diameter rebar in place above the smaller diameter rebar; and

wherein each pair of legs defines a lower gap dimension.

8. A rebar clip for joining a larger diameter rebar to a smaller diameter rebar transverse to the larger diameter rebar, the rebar clip comprising:

a clip body defined along x, y and z orthogonal directions;

the clip body including first and second pairs of resilient legs extending in the z-direction and defining first and second lower arches aligned parallel to the x-direction;

the clip body including first and second pairs of resilient arms extending in the z-direction away from the legs, the arms defining first and second upper cradles aligned parallel to the x-direction;

the clip body including first and second bridges joining distal ends of the first pair of arms to distal ends of the second pair of arms, the bridges and the arms defining first and second upper arches aligned parallel to the y-direction;

the lower arches, the upper cradles and the upper arches each including curved portions of the larger diameter; and

pairs of diameter reducing tabs extending into either the lower arches or the upper arches for engaging the smaller diameter rebar;

wherein the diameter reducing tabs extend into the lower arches so that the clip can hold the larger diameter rebar in place above the smaller diameter rebar; and

wherein the legs have a leg thickness in the x-direction; and

wherein the tabs have a tab thickness in the x-direction, the tab thickness being equal to the leg thickness.
