ABSTRACT:
A connector unit for a number of different coupling applications such as for interconnecting a pair of pipes or other structural parts which must be mounted near each other and at an angle with respect to each other. The connector unit includes a pair of side members which are spaced apart and to which are mounted the structural parts to be interconnected. Each side member has a respective ring rotatably mounted thereon by a first set of balls, and the two rings are rotatably coupled to each other by a second set of balls. Each set of balls is in an annular race formed by a pair of mating grooves. The balls of each set are fed into a respective race through a hole in the respective ring, then the hole is plugged to keep the balls in place. The race between the two rings is inclined at an angle relative to the race between each side member and the respective ring. Thus, rotation of one ring relative to the other ring will cause a change in the angular orientation of the side members relative to each other without rotating the side members relative to each other and without allowing one side member to move toward or away from each other. A pair of gears can be provided to rotate each ring relative to its corresponding side member.
