摘要： 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.

摘要： 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.
摘要翻译： 公开了一种具有较大直径近端部分和较小直径远端部分的减震伸缩工具手柄。 当手柄部分在施加到工具把手上的冲击时朝向彼此望远镜时，手柄部分中的内部弹簧被压缩。 手柄部分中的引导机构限制了手柄部分之间的滑动运动的程度并防止手柄部分的相对运动。 手柄部分中的一个或多个擦拭物擦除远端部分上可能进入弹簧区域的任何雪，水或碎屑。 弹簧可以位于工具把手的近端部分或远端部分内。

摘要： An improved snow shovel is disclosed which has a telescoping handle and a detachable blade. Inside the handle is a compression spring which compresses under load or shock from striking an object submerged in the snow and when the shovel is lifted, the spring decompresses and assists in discharging the load.
