Abstract
A sports device configured to generate thermal energy to warm surfaces. In one implementation, the sports device embodies a lacrosse stick with a shaft and head. The shaft includes a thermal core with a phase change material that can retain and dissipate heat over an extended period of time.
Claims20
A handle, comprising:
- an elongate shaft with a bore extending therethrough, the bore having a center axis and an inner surface;
- a heat source located in the bore so that heat emanates from the center axis towards the inner surface;
- and
- phase change material disposed inside of the bore in space between the heat source and the inner surface.
1 more element
Sports equipment, comprising:
- a heated handle with a location that increases and decreases in temperature, the heated handle comprising:
- a hollow tube;
- a heat source in the hollow tube;
- and
- phase change material disposed at the location in space between the heat source and the hollow tube.
2 more elements
A system to heat a handle, comprising:
- an elongate, hollow shaft;
- and
- a thermal core removable from the elongate, hollow shaft, the thermal core comprising a cylinder enclosing a volume, a heat source centrally-located in the cylinder to generate heat that emanates outwardly into the volume, and a phase change material filling the volume and interposed between the heat source and the cylinder.
