ABSTRACT:
One embodiment of an improved self-centering mechanism restoring the handlebar or control of an electronic exercise bicycle or video game bike to the straight ahead position when the rider removes his hands from the handlebars or controls. The self-centering mechanism is configured with a compression spring (52) assisting and pressurizing a mechanical device comprised of two opposing circular ball ramps (32) and (44) with radial tapered depth grooves (42). Round balls (40) of similar diameter to the radius of the depth grooves (42) are situated in the grooves (42) between the opposing ball ramps (32) and (44). The compression spring (52) is located over a connecting bolt (56) which connects the ball ramps (32) and (44) to a shaft (26) that is supported with bearings (22) and (28) in a housing (24). Below the spring assembly is the mount assembly for the potentiometer (66), which sends the data signals communicating the rotation amount of the handlebars to the video game. The anti-rotation pin (62), which is stabilized by mount for anti-rotation pin (60), prevents potentiometer (66) from rotating as a result of anti-rotation plate (64) riding against anti-rotation pin (62). Other embodiments are described.
