Abstract: A stationary exercise bicycle is provided having a frame, a resistance member, a drive assembly, a right pedal, a left pedal, a seat and an adjustable seat mechanism utilizing a rack. Assembly and disassembly of a three piece crank arm assembly is accomplished without requiring the assembling and disassembling of the entire drive assembly. The stationary exercise bicycle also provides a variety of users with an optimum seat position and with a convenient latch mechanism to adjust the position of the seat.

Abstract: An exercise apparatus includes a frame that is adapted for placement on the floor, a pivot axis supported by the frame, a pedal bar which has first and second ends, a pedal that is secured to the pedal bar, an ellipse generator, and a track. The ellipse generator is secured to both the pivot axis and to the first end of the pedal bar such that the first end of said pedal bar moves in an elliptical path around the pivot axis. The track is secured to the frame and engages the second end of said pedal bar such that the second end moves in a linear reciprocating path as the first end of the pedal bar moves in the elliptical path around said pivot axis. Consequently, the pedal also moves in a generally elliptical path. As the pedal moves in its elliptical path, the angular orientation of the pedal, relative to a fixed, horizontal plane, such as the floor, varies in a manner that simulates a natural heel to toe flexure. The apparatus can also include a resistance member, a data input member, and a control member.

Abstract: An exercise apparatus includes a frame, a pivot axis supported by the frame, a pedal lever, a coupler for pivotally coupling a first end of the pedal lever to the pivot axis at a predetermined distance from the pivot axis such that the first end moves in an arcuate pathway around the pivot axis, a guide member supported by the frame and engaging a second end of the pedal lever such that the second end of the pedal lever moves in a reciprocating pathway as the first end of the pedal lever moves in the arcuate pathway, and a pedal having a toe portion and a heel portion, the pedal being pivotally coupled with the second end of the pedal lever such that the toe portion is intermediate the heel portion and the pivot axis and the heel portion is raised above the toe portion when the second end moves in the reciprocating pathway in a direction away from the pivot axis.

Abstract: A multi-station pinball game is provided by the present invention having a rotatable playfield controlled by a programmable microprocessor which selectively indexes the playfield to each individual station, in a desired order, for sequential play of the game by several players seated around the playfield at their individual playing stations.
