Abstract

Claims (52)

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 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;

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; and

the diameter reducing tabs extend no closer to each other than said gap dimension.

4. The rebar clip of claim 3 , wherein:

the legs of each pair of legs are downwardly flared away from each other to provide a tapered guide into the gap for a lower one of the crossed rebars;

and the tabs associated with each pair of legs define a vertical constant width path of width substantially equal to the gap dimension.

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.

8. The rebar clip of claim 7 , 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.

9. The rebar clip of claim 8 , wherein:

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

10. The rebar clip of claim 8 , wherein:

each pair of legs defines a lower gap dimension; and

the diameter reducing tabs of each pair of tabs extend no closer to each other than said gap dimension.

11. The rebar clip of claim 10 , wherein:

the legs of each pair of legs are downwardly flared away from each other to provide a tapered guide into the gap for a lower one of the crossed rebars;

and the tabs associated with each pair of legs define a vertical constant width path of width substantially equal to the gap dimension.

12. The rebar clip of claim 8 , wherein:

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

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

13. The rebar clip of claim 12 , wherein:

the tabs are flush with sides of each pair of legs closest to the other pair of legs.

14. The rebar clip of claim 7 , wherein:

the diameter reducing tabs extend into the upper arches so that the clip can hold the smaller diameter rebar in place above the larger diameter rebar.

15. The rebar clip of claim 14 , wherein:

each pair of the diameter reducing tabs includes opposed obliquely downward facing concave corners for engaging the smaller diameter rebar from above.

16. The rebar clip of claim 14 , wherein:

each pair of tabs define a vertical slot therebetween for receiving a guide bar.

17. A string of clips including the rebar clip of claim 16 , each of the clips being substantially identical and the clips being joined together with the vertical slots between tabs being aligned with each other for receiving the guide bar to guide the string of clips.

18. The rebar clip of claim 7 , wherein the clip comprises an integrally molded plastic clip.
