Patent Images
1. A power transfer hinge comprising:
- a first hinge leaf having a first rear surface having a first recess and at least two first knuckles having bores axially aligned to a common bore;
a second hinge leaf having a second rear surface having a second recess and at least two second knuckles, interleaved with said first knuckles, having bores axially aligned to said common bore;
a pair of pins, disposed in said common bore, for pivotally engaging said first and second hinge leaves;
a first passageway entering said common bore through a first opening and connecting said common bore to said first recess;
a second passageway entering said common bore through a second opening and connecting said common bore to said second recess, the second passageway and the first passageway having a common center line for entering said common bore; and
a cable passing through said first recess, the first passageway, said common bore, the second passageway, and the second recess.

Abstract
A hinge for transferring power between a wall jamb and a door. The hinge includes a pair of hinge leaves having interleaved knuckles axially aligned to share a common bore. The hinge pivots about upper and a lower pins disposed in the common bore. A coaxial cable enters a recess in a rear surface of one hinge leaf, passes through a longitudinal passageway in the hinge leaf, across the common bore, through a longitudinal passageway in the other hinge leaf, and exits a recess in the rear surface of the other hinge leaf. The passageways are aligned and have tapered openings to enable the cable to be routed after the hinge is mechanically assembled.

7. A method for constructing a hinge for transferring power comprising steps of:
-
providing a hinge having a pair of hinge leaves having interleaved knuckles sharing a common bore, said hinge further having a pair of pins disposed in said common bore pivotally engaging said hinge leaves; making a recess in a rear surface of each said hinge leaf; making a longitudinal passageway with an opening into said common bore to connect said common bore to said recess in each said hinge leaf, each said passageway to share a common center line entering said common bore; and routing a cable to enter one said recess, pass through one said passageway, pass through said common bore, pass through the other said passageway, and exit the other said recess. - View Dependent Claims (8, 9, 10, 11)
