Claim:
A self-closing invisible hinge for supporting a door to a mounting structure for swinging movement between a closed and an opened position and for urging and returning the door to its closed position from its opened position, said self-closing invisible hinge comprising: a pair of hinge bodies having a front portion and a rear portion, each of said pair of hinge bodies being connectable to the associated one of the door and the mounting structure with each said front portion facing outwardly from the associated one of the door and mounting structure; a link device connected to said pair of hinge bodies for permitting swinging movement of said pair of hinge bodies relative to each other between its closed and opened positions, said link device having at least one channel extending through at least one of said pair of hinge bodies, said at least one channel extending from a position generally adjacent to the door to a position generally adjacent the mounting structure, said at least one channel being concealed when viewing said front portion of said pair of hinge bodies; a closing device operatively connected between said link device and one of said pair of hinge bodies for urging said link device and said pair of hinge bodies to the closed position, said closing device having a spring device for providing a spring bias between said link device and said one of said pair of hinge bodies for urging said link device and said pair of hinge bodies to the closed position; an adjustment device operatively connected with said spring device, said adjustment device selectively varying the magnitude of said spring bias of said spring device, said spring device and said adjustment device extending rearwardly from said rear portion of said one of said pair of hinge bodies and adapted to be located and enclosed within an opening in the associated one of the door and mounting structure; and an electrical wire extending through said at least one channel of said link device and extending to said rear portion of said pair of hinge bodies, said electrical wire providing electrical communication therethrough.
