Cable support systems
Cable Support Systems for supporting an object at a desired distance below an overhead beam or other overhead structure are provided. Novel clamps for clamping to the overhead structure are fitted to support cables that encircle objects to be supported by the cable support systems. The novel clamps have internal methods to support the cables. The cables are then encircled around the objects and fixed relative to the clamp. The distances between the object and the clamps may be precisely controlled.
1. A clamp for a cable support system to suspend an object from an overhead beam comprising:
a. a generally “C” shaped clamp body;
b. a threaded fastener threadingly received within one leg of the “C” shaped body to clamp the “C” shaped body onto the overhead beam;
c. a vertical bore through the clamp body for receiving a cable to be suspended from the overhead beam; and
d. a passage extending downwardly within the clamp body at an acute angle to the vertical bore and communicating with the bore;
e. a wedge slidable within the passage and extending into the bore;
f. a spring within the passage urging the wedge toward the bore so that a cable may be inserted upwardly into the bore against the force of the spring; and
g. release levers fixed to the wedge and extending outwardly through slots in the clamp body to selectively move the wedge against the force of the spring to release the cable.
2. A cable support system for hanging an object at a desired distance below an overhead beam comprising:
a. a clamp having a generally “C” shaped clamp body with a threaded fastener threadingly received within one leg of the “C” shaped body to clamp the “C” shaped body onto the overhead beam and a vertical bore through the clamp body to receive a cable to be suspended from the overhead beam, the vertical bore having a downwardly extending passage communicating with it at an acute angle with a wedge slidable within the passage and being urged toward the bore by a spring within the passage, the wedge having release levers extending outwardly through slots in the “C” shaped body to release the wedge from the cable for movement of the cable;
b. an object to be suspended by the cable at a predetermined height below the beam;
c. a cable grip having first and second bores extending longitudinally through a housing wherein the first bore permits free movement of a cable relative to the cable grip housing and the second bore has wedge means associated therewith that permit movement of the cable relative to the second bore in one direction but prevent movement of the cable in the other direction; and
d. the cable suspended from the clamp being passed through the first bore of the cable grip and thereafter being passed around the object and then being positioned within the second bore of the cable grip.
