Abstract

A rail clamp is provided comprising a pair of substantially identical opposing side pieces or members in which the side members have a means for slidably interlocking with one another at one end of the side members, a semicircular portion located in in approximately the middle of each side member, a hole for fastening the two side members together after they have interlocked around a rail, and a hole for mounting auxiliary equipment to the rail clamp. The interlocking end comprises a hooking end and a receiving end such that the hooking end of the first side member can slidably interlock with the receiving end of the opposing side member. The hooking end has a hooking lip which forms a hooking channel and the receiving end has a receiving lip which forms a receiving channel such that the hooking lip slides into the receiving channel and the receiving lip slides into the hooking channel when the two opposing side members are brought into a face-to-face relationship.

Dependent claims

A rail clamp comprising a pair of substantially identical opposing side members, each side member having

(a) a parallel slidably interlocking means at one end of the side member having a receiving means and a hooking means wherein the hooking means includes a hooking lip which forms a hooking channel and the receiving means includes a receiving lip which forms a receiving channel such that the hooking lip and hooking channel of the first side member slidably interlocks with the receiving channel and receiving lip, respecitvely, of the second side member to prevent the side members from pivoting about a rail,
(b) a holding means for mounting auxiliary devices to the clamp at the other end of the side member,
(c) a semicircular portion disposed between the ends and adapted to surround approximately one half of the rail between each of the side members when positioned against the rail, and
(d) a means for fastening the individual side members together when the pair of side members have the slidably interlocked means interlocked together with a rail positioned between the respective semicircular portions.
