PCT No. PCT/US95/10082 Sec. 371 Date Jan. 10, 1997 Sec. 102(e) Date Jan. 10, 1997 PCT Filed Jul. 25, 1995 PCT Pub. No. WO96/03187 PCT Pub. Date Feb. 8, 1996The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure (4), a wheel chassis (10), a wheel support (52), at least two wheels (50), and mechanisms which position the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The positioning mechanisms include tie rods (18), yokes (84, 86), gear sets (106), and externally mounted rods or panels (116). A post (30) on the bottom of the enclosure may include a threaded portion which is engaged by a nut (36) to rotationally secure the position of the wheel chassis, or the post may include a portion (94) of enlarged diameter supporting a spring (104) which biases the wheel chassis into the post. A brake (122) is provided to allow the user to slow or stop the skate in a controlled manner.
