Abstract
A shock-absorbing telescoping tool handle is disclosed having a larger diameter proximal portion and a smaller diameter distal portion. An internal spring in the handle portions is compressed when the handle portions telescope towards each other upon shock being applied to the tool handle. Guide mechanisms in the handle portion limit the extent of sliding motion between the handle portion and prevent relative motion 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. The spring may be located within the proximal portion or the distal portion of the tool handle.

A shock-absorbing tool handle comprising:
- a tubular proximal portion and a tubular distal portion, each portion having two ends;
- 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;
- first and second spring keepers in the handle;
- the first spring keeper being one end of the distal portion;
- the second spring keeper being a dowel forcibly received 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.
A shock-absorbing tool handle comprising:
- a tubular proximal portion and a tubular distal portion, each portion leaving two ends;
- 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 proximal portion of 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 proximal portion and a second spring keeper engagable with the proximal portion;
- the first spring keeper being one end of the distal portion;
- the second spring keeper being a dowel forcibly received in the proximal portion;
- 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.
