Apparatus for transferring electric power between a closable member and a frame
First Claim
1. An apparatus for transferring electric power between a closable member and a frame when said closable member is moved between an open position and a closed position, said apparatus comprising:
- a) a first housing and first face plate for connecting to said frame, wherein said first face plate includes a first hole, and wherein said first face plate is fixed in place relative to said first housing;
b) a second housing and second face plate for connecting to said closable member, wherein said second face plate includes a second hole, and wherein said second face plate is fixed in place relative to said housing;
c) a first elbow assembly rotatably disposed in said first hole;
d) a second elbow assembly rotatably disposed in said second hole; and
e) a tube having a longitudinal axis and opposite first and second ends, wherein said first end of said tube is slidably receivable by said first elbow assembly along said longitudinal axis, and wherein said second end of said tube is slidably receivable by said second elbow assembly along said longitudinal axis, enabling relative movement between said tube assembly and said first and second elbow assemblies when said closable member is moved between said open position and said closed position.

Abstract
A device for transferring electrical power between a frame and a closable member such as a door includes a first housing and face plate disposed in an opening in the frame and a second housing and face plate disposed in an opening in the closable member edge. The openings are positioned so that when the closable member is closed the openings are aligned. A hollow elbow assembly is rotatably disposed and secured in each hole. A tube having a pivot guide at each end is rotatably and axially slidable in each elbow assembly. A slot in each elbow assembly allows the tube to pivot. A wire bundle in the tube is connectable to wire leads. Boots may be supplied around the tube/elbow assemblies'"'"' junctions to exclude water. Thus, the wire bundle is fully contained within a protective, articulated, armored sheath to prevent wear, chafing, breakage, and vandalism.
