ABSTRACT:
The present invention is a joint assembly for allowing relative rotational movement of a camera relative to a stationary base structure. The assembly has a first flexible member which allows the camera to pan the surrounding are and a second flexible member which allows the camera to tilt. Each flexible member has a first surface facing a first direction and second surface facing a second opposite direction. One end each flexible member is folded over onto itself so that a portion of the second surface faces the first direction. The flexible members are constructed in an essentially radial shape to define a radial path. When an end of a flexible member moves along the arcuate path the member rolls over itself. That is, the portion of the flexible member that is rolled over, has its second surface facing the first direction instead of the second direction. The flexible member is preferably constructed with a plurality of electrical lines or wires, wherein all the wires move in an orderly pattern without entanglement.
