Abstract

A structural clip includes two connecting legs extending from a resilient spring means with a securing loop at the end of each leg. The angles defined by the legs and by each leg and the spring means when the securing loops are connected to a bottom support member secure that member and a contacting top support member in any spatial relationship one to the other without auxiliary tools. An embodiment useful over a range of support member diameters for perpendicular or parallel reinforcement member alignment, and a method for using the clip also are disclosed.

Claims

1. A clip connector, comprising:

resilient spring means having two, off-set legs of unequal length and uniform cross-section, each off-set leg having an end and extending from the spring means to define interior and exterior angles in relation to its direction from the spring means;

wherein the longer leg is straight and comprises a transverse loop of predetermined radius at its end;

wherein the shorter leg comprises a first angled portion, a second angled portion, and a loop of predetermined radius at the end of the second angled portion at a predetermined obtuse angle, wherein each angled portion defines a predetermined angle one to the other and to the longer leg;

whereby the longer leg is at a 135 degree exterior angle to the second angled portion of the shorter leg in an x-y axis planar orientation; and

whereby the first angled portion of the shorter leg is at a 100 degree angle to the second angled portion of the shorter leg in an y-z axis planar orientation.

2. The apparatus of claim 1, wherein resilient spring means comprises an off-set loop of predetermined radius and the longer leg defines an exterior angle of 90 degrees to the first angled portion of the shorter leg in an x-z axis planar orientation.

3. The apparatus of claim 2, wherein the radius of the off-set loop is 0.85 centimeters.

4. The apparatus of claim 1, wherein the radius of each loop is 0.85 centimeters.

5. The apparatus of claim 1, wherein each loop can receive material of uniform diameters ranging from ⅜

inch to ⅝

inch.

6. The apparatus of claim 2, wherein the off-set loop, semicircular loops, and legs comprise material selected from the group consisting of metal, high grade polyvinylchloride, high grade poly-carbon, and high grade composite materials comprising carbon fibers, such as graphite.

7. The apparatus of claim 1, wherein the loop at the end of the second angled portion of the shorter leg is a semicircle.

8. The apparatus of claim 1, wherein the transverse loop at the end of the longer leg is a semicircle.

9. The apparatus of claim 1, wherein the transverse loop at the end of the longer leg is greater than a quarter-circle but less than a semicircle.

14. A method of connecting concrete reinforcement steel, the method comprising the steps of:

providing a clip apparatus according to claim 1;

providing at least two reinforcement rods;

positioning the two rods in a predetermined alignment wherein one member is below and contacting the second member;

securing the apparatus loop at the end of the shorter leg around the bottom rod;

extending the apparatus longer leg such that the attached loop provides a fulcrum for the apparatus whereby the forces engaging the rods from the resilient spring means hold the rods in the desired alignment; and

securing the apparatus loop at the end of the apparatus longer leg around the bottom rod such that the rods are secured in the desired alignment by the clip.

15. The method of claim 14 wherein the predetermined alignment is parallel.

16. The method of claim 14 wherein the predetermined alignment is perpendicular.

17. The method of claim 14, wherein the predetermined alignment defines an acute interior angle between the rods.

10. A clip connector for securing bars for concrete reinforcement, comprising a predetermined length of 2 millimeter spring wire, the length of wire sufficient to further comprise:

an off-set loop having a radius of 0.85 centimeters defining various internal and external tangents thereto and two extending lengths;

a first extending length from the off-set loop comprising a straight length having an end comprising a transverse loop having a radius of 0.85 centimeters wherein the overall length from the transverse loop to an external tangent of the off-set loop parallel to the transverse loop is 10 centimeters;

a second extending length from the off-set loop comprising a first angled portion 1.7 centimeters in length and perpendicular to the first extending length in an x-z axis planar orientation, a second angled portion 3.5 centimeters in length having an end, and a loop having a radius of 0.85 centimeters at the end of the second angled portion at a predetermined obtuse angle to the second angled portion, wherein the first angled portion and the second angled portion define a 100°

angle one to the other in an y-x axis planar orientation, the second angled portion defines a 135°

angle to the first extending length in an x-y axis planar orientation, and wherein the overall length from the loop at the end of the second angled portion to an inside tangent of the off-set loop parallel to the obtuse angled loop is 4.0 centimeters.

11. The apparatus of claim 10, wherein the obtuse angled loop at the end of the second angled portion is a semicircle.

12. The apparatus of claim 10, wherein the transverse loop at the end of the first extending length is a semicircle.

13. The apparatus of claim 10, wherein the transverse loop at the end of the first extending length is greater than a quarter-circle but less than a semicircle.
