Abstract

A motorcycle rider is heated by the steps of: transferring heat from atmosphere to a thermally conductive element mounted on a motorcycle by the Peltier effect; and circulating working liquid in a closed cycle from the thermally conductive element, through a garment worn by the motorcycle rider via an inlet coupling thereto and an outlet coupling therefrom, and then back to the thermally conductive element. In an alternative arrangement, a motorcycle rider is cooled by the steps of: circulating working liquid in a closed cycle through a garment worn by the rider via an outlet coupling therefrom, via a thermally conductive element mounted on the motorcycle, and then back to the an inlet coupling to the garment; and transferring heat from the thermally conductive element to atmosphere by the Peltier effect. In either case, both the inlet coupling and the outlet coupling are separable to allow the motorcycle rider to leave the motorcycle while still wearing the garment.

Claims

1. A method of heating a motorcycle rider by the steps of:

transferring heat from atmosphere to a thermally conductive element mounted on a motorcycle by the Peltier effect; and

circulating working liquid in a closed path from said thermally conductive element, through a garment worn by the motorcycle rider via an inlet coupling thereto and an outlet coupling therefrom, and then back to the thermally conductive element;

a reservoir for liquid being coupled to said closed path;

both the inlet coupling and the outlet coupling being separable to allow the motorcycle rider to leave the motorcycle while still wearing the garment.

2. A method of cooling a motorcycle rider by the steps of:

circulating working liquid in a closed path through a garment worn by the rider via an outlet coupling therefrom, via a thermally conductive element mounted on the motorcycle, and then back to an inlet coupling to said garment;

a reservoir for liquid being coupled to said closed path; and

transferring heat from the thermally conductive element to atmosphere by the Peltier effect;

both the inlet coupling and the outlet coupling being separable to allow the motorcycle rider to leave the motorcycle while still wearing the garment.

3. A heating/cooling system for a motorcycle rider, comprising:

a garment adapted to heat or cool a motorcycle rider wearing the garment, the garment being provided with ducting coupled to an inlet coupling and an outlet coupling and adapted for circulating working liquid from the inlet coupling to the outlet coupling via the said ducting;

a thermo-electric device mounted on a motorcycle and having a first face and a second face and adapted to be electrically coupled to a source of direct current mounted on the motorcycle for operatively transferring heat by the Peltier effect from the first face to the second face or vice-versa depending upon the sense of the direct current, the first face being thermally coupled to a metal block exposed to atmosphere, and the second face being thermally coupled to a thermally conductive element through which working liquid from said outlet coupling is adapted to pass in heat exchange relation with said element before passing back to said inlet coupling;

a closed path working liquid circulation system mounted on the motorcycle, said system comprising the said ducting, and a pump and connections for circulating working liquid from the outlet coupling to and through the thermally conductive element and back to the inlet coupling;

a reservoir for liquid being coupled to said closed path; and

a fan mounted on the motorcycle and adapted to cause passage of atmospheric air past said metal block in heat exchange relation therewith.

4. A heating/cooling system according to claim 3, wherein each of the inlet coupling and the outlet coupling respectively comprise a double self-closing valve coupling comprising a first coupling member connected directly to the ducting in the garment and a second coupling member connected to tubing providing said connections in said circulation system, one said coupling member being a male member and the other coupling member being a female member, and each coupling member being provided with an automatic shut-off valve adapted to prevent flow in either direction when the two coupling members are de-coupled from each other, the two coupling members being arranged automatically to open when the two coupling members are coupled together.

5. A heating/cooling system according to claim 4, in the form of a vest or jacket adapted to be worn beneath protective clothing for motorcycle riders;

the ducting being sewn between inner and outer layers of the said vest or jacket.

6. A heating/cooling system according to claim 4, wherein each said coupling member presents a flat face in its de-coupled condition so as to prevent or restrict ingress of dirt, grease or other foreign matter.

7. A heating/cooling system according to claim 3, further comprising a temperature control system comprising a thermistor mounted adjacent the outlet coupling on the motorcycle side in thermally conductive relation with the working fluid, the thermistor being coupled into a control circuit, whereby current through the thermistor is adapted to control direct current passing to the thermo-electric device so as to increase that current when the system is operating in heating mode and the temperature sensed by the thermistor is below a preset range and to reduce that current when the temperature sensed by the thermistor is above a preset range, and so as to increase that current when the system is operating in cooling mode and the temperature sensed by the thermistor is above a preset range and to decrease that current when the temperature sensed by the thermistor is below a preset range.

8. A heating/cooling system according to claim 7, wherein the temperature control system is provided with an automatically operable override adapted to protect the battery and charging circuits of the motorcycle itself by cutting off current to the thermo-electric device when excessive draining of the motorcycle battery is detected.
