Abstract
A rotary joint includes a socket rod having a socket rod flange with a basically spheroid con-cave bearing surface at a first end, a housing nut encircling the socket rod and having a threaded wrenching head, a ball rod having a basically spheroid convex bearing surface and threaded side walls around the convex bearing surface, and a joint actuator configured to actuate relative movement of the socket rod flange and the ball rod. A diameter of the threaded side walls of the ball rod corresponds to a diameter of the threaded wrenching head of the housing nut.
Claims15
A rotary joint comprising:
- a socket rod comprising a socket rod flange with a basically spheroid concave bearing surface at a first end;
- a housing nut encircling the socket rod and comprising a threaded wrenching head;
- a ball rod comprising a basically spheroid convex bearing surface and threaded side walls around the convex bearing surface;
- and
- a joint actuator configured to actuate relative movement of the socket rod flange and the ball rod;
- a diameter of the threaded side walls of the ball rod corresponding to a diameter of the threaded wrenching head of the housing nut.
A framework construction kit, comprising:
- at least one rotary joint comprising:
- a socket rod having a socket rod flange with a basically spheroid concave bearing surface at a first end;
- a housing nut encircling the socket rod and having a threaded wrenching head;
- a ball rod having a basically spheroid convex bearing surface and threaded side walls around the convex bearing surface;
- and
- a joint actuator configured to actuate relative movement of the socket rod flange and the ball rod;
- a diameter of the threaded side walls of the ball rod corresponding to a diameter of the threaded wrenching head of the housing nut;
- and
- at least one interconnection strut connected to a second end of the socket rod of the at least one rotary joint or connected to the ball rod of the at least one rotary joint.
A framework, comprising:
- a plurality of rotary joints comprising:
- a socket rod having a socket rod flange with a basically spheroid concave bearing surface at a first end;
- a housing nut encircling the socket rod and having a threaded wrenching head;
