Abstract

A clamp for clamping two elongate members together, wherein one elongate member has substantially radial ridges, wherein the clamp includes a first clamp element having a first clamp surface; a second clamp element having a second clamp surface; and a member for securing the first clamp element to the second clamp element in a secured position with the first and second clamp surfaces facing each other, wherein the first and second clamp surfaces in the secured position define first and second channels for clamping two substantially elongate members, and wherein at least one channel of the first and second channels has a plurality of teeth spaced longitudinally along the channel and defining gaps therebetween.

Claims

1. A clamp for clamping two elongate members together, wherein one elongate member has substantially radial ridges, the clamp comprising:

a first clamp element having a first clamp surface means;

a second clamp element having a second clamp surface; and

means for securing the first clamp element to the second clamp element in a secured position with the first and second clamp surfaces facing each other, wherein the first and second clamp surfaces in the secured position define first and second channel means for clamping two substantially elongate members, and wherein at least one channel means of the first and second channel means has a plurality of flat-topped teeth spaced laterally and longitudinally along the at least one channel means and defining gaps therebetween.

2. A clamp according to claim 1, wherein the first and second clamp surface means each have first and second grooves which define the first and second channel means in the secured position.

3. A clamp according to claim 2, wherein the first and second clamp elements each have a plurality of said teeth spaced longitudinally along the first grooves so as to define the gaps, and wherein the second grooves are substantially smooth in a longitudinal direction.

4. A clamp according to claim 3, wherein the first and second clamp elements have intersecting opposed arms defining the first grooves and wherein a plurality of said teeth are provided on each opposed arm.

5. A clamp according to claim 1, wherein each tooth of the plurality of teeth has a width in the longitudinal direction selected to fit between substantially radial ridges of the one elongate member.

6. A clamp according to claim 1, wherein the first and second clamp elements each have an opening arranged substantially transverse to the first and second channel means, and wherein the means for securing comprises threaded means for passing through the opening of one clamp element of the first and second clamp elements and for threadedly engaging the other element of the first and second clamp elements whereby the first and second clamp elements are releasably securable in the secured position.

7. A clamp according to claim 6, wherein the threaded means further has a head portion, and wherein the opening of the one clamp element is sized to non-threadedly receive the threaded member with the one clamp element abutting the head portion whereby lateral pivot of the one clamp element relative to the other clamp element is permitted during tightening toward the secured position.

8. A clamp according to claim 7, wherein the head portion is a slotted and hex-shaped screw head.

9. A clamp according to claim 1, wherein the first and second channel means are substantially parallel.

10. A clamp according to claim 1, wherein at least a portion of at least one of the first and second clamp elements is electrically conductive so as to define electrical connection between the first and second channel means.

11. A clamp according to claim 1, wherein at least the first and second clamp surfaces are made of an electrically conductive material.

12. A clamp according to claim 1, wherein the first and second clamp elements are made of cast-bronze.

13. A clamp according to claim 1, wherein the first and second channel means are substantially perpendicular.

14. A clamp according to claim 1, wherein each channel means of the first and second channel means has a plurality of said teeth spaced longitudinally along each channel means.
