Patent ID: 7179080

Claim:
A tube bending fixture comprising: a frame, a lower tube support pivotally mounted to said frame between a first and a second position about a first axis, an upper tube support pivotally mounted to said frame between a first and a second position about a second axis, a bar slidably mounted to said upper tube support and movable between an extended and a retracted position, a plurality of lower mandrels mounted to said lower tube support, each lower mandrel dimensioned to fit within one end of a tube to be bent, a plurality of upper mandrels mounted to said bar, one of said upper and one of said lower mandrels being aligned with each other when said upper and lower tube supports are in said first pivotal position, each said upper mandrel dimensioned to fit within a second end of the tube to be bent when said bar is in said extended position, each said upper mandrel being spaced from the second end of the tube to be bent when said bar is in said retracted position, a lock mechanism which selectively retains said upper and lower tube supports in said second pivotal position, a first gear secured to said lower tube support coaxial with said first axis and a second gear secured to said upper tube support coaxial with said second axis, wherein said first and second gear are in mesh with each other so that said upper tube support and said lower tube support pivot in unison with each other relative to said frame.
