Claims8
In a skateboard type device, a hand operated control system for transmitting a signal from a user's hand to a running gear of said device, comprising in combination;
- a. a hydraulic master cylinder having an output port, for displacing fluid through said output port in response to a mechanical signal from a user's hand,
- b. a hydraulic slave cylinder connected to said running gear, having an input port for receiving said fluid and translating it to a mechanical signal for effecting said running gear, and
- c. a resilient helically coiled self-storing tube assembly connecting said input and output ports while allowing said master cylinder to be freely moved relative to said slave cylinder without interfering with said signal.
