Abstract
A manpower-driven device has a bi-directional rotational input for providing output to the input end of a constant rotating direction output transmission device, which is used to drive a loading wheel train, wherein the direction of the driving input can be freely selected by the user. The manpower-driven device includes a rotation direction detection device and a sound generator whose sound output depends on the detected rotation direction.
Claims21
A manual driving device having a bi-directional input and that generates sound in response to a driving direction, comprising:
- a foot or hand driven input device (101) for receiving a rotary input in either of two directions or a reciprocating rotary input;
- a constant output direction transmission device (102) for receiving a bi-directional input from the foot or hand driven input device (101) and producing a constant direction output having only one rotational direction, wherein a speed ratio between an input end and an output end of the constant output direction transmission device is fixed or variable;
- a load connected to be directly or indirectly driven by the constant output direction transmission device;
- a rotating direction detection device (1010) for detecting a direction of the bi-directional input to the constant output direction transmission device (102);
- and
- a sound generating device (1020) connected to and actuated by the rotating direction detection device (1010) to generate sound and terminate sound generation depending on said direction of the bi-directional input.
