Abstract
A shock-absorbing telescoping tool handle is disclosed having tubular, larger diameter proximal and a smaller diameter distal portions. An internal spring between the handle portions is compressed when the handle portions telescope toward each other. Guide mechanism in the handle portions limits the extent of sliding motion between the handle portions and prevents relative rotation of the handle portions. One or more wipers in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area.

A shock-absorbing tool handle comprising:
- a tubular proximal portion and a tubular distal portion;
- the distal portion being adapted to receive a tool;
- the proximal portion being larger in cross-section than the distal portion and slidable over the distal portion in telescoping relationship toward the tool;
- a spring located within the handle, and compressible when the portions telescope toward each other when force is applied in an axial direction;
- a first spring keeper in the distal portion and a second spring keeper in the proximal portion;
- and
- guide mechanism in the handle portions positioned to limit the sliding motion between the portions and to permit the spring to be compressed between the keepers when shock is applied to the handle.

- and
- at least one wiper in the handle surrounding the distal portion and engagable with the proximal portion to prevent the entry of contaminants between the telescoping portions.
