ABSTRACT:
A foot-controlled mechanical device to greatly enhance the convenience and efficacy of specialized cassette players; specifically, a compatible accessory which allows hands-free operations of cassette players designed as song learning devices for instrumentalists. The carriage (22) contains the cassette player, holding it secure and shielding it against damage during operations. Pivoting foot-pedal (34) and mobile pivoting foot-pedal (40) are supported above the cassette player in an operative mode. The resistance/stop mechanisms (26L) and (26R) support the foot-pedals (34) and (40), provide adjustable resistance for customized tension, provide immediate reset after each use, and serve as stop mechanisms to avoid damage to the cassette player. Pivot-shaft (32) is secured in the bushings (30) to provide a strong support and pivot-axis for foot-pedals (34) and (40). A center support (38) reinforces pivot-shaft (32) and provides a lateral guide for foot-pedal (34). Foot-pedal (34) is free to pivot up and down in-place to operate the rewind/review function of the cassette player. Mobile foot-pedal (40) also pivots on shaft (32) and has the additional capacity to be shifted forward and back and from side to side to provide access to three separate functions: play, fast forward, and stop. The anti-sway cartridge (42) provides lateral stability for mobile foot-pedal (40) during operations. The controls of the cassette player are contacted and engaged with the foot-pedal buttons (44) during operations. Designed with the principle of economy, "less is more", this highly effective operational mechanism serves as an instrumentalists foot-stand in addition to its intended primary functions.
