Patent number: 6524025Abstract: A means for linearly connecting two non-circular pipes mainly includes a bar, upper and lower pads put around the bar, and a collar. The bar has two externally threaded ends adapted to screw into internally threaded holes preformed in the non-circular pipes. The upper and lower pads respectively have a cross section the same as that of a bore of the non-circular pipes, and are divided into an inner section and an outer section by a flange, such that the outer sections of said upper and said lower pads can be inserted into the pipes to synchronously rotate along with the pipes. The collar has cross section and outer diameter the same as that of the pipes and is initially put around the inner section of the upper pad, so that the collar can be downward moved to enclose the inner sections of the upper and the lower pads at the same time to confine them and accordingly the two pipes to a vertically aligned position.Type: GrantFiled: February 27, 2001Date of Patent: February 25, 2003Assignee: Protrend Co., Ltd.Inventor: Henry Chen
