  • Patent number: 5749613
    Abstract: A tool handle extension is permanently or semi-permanently attachable to a tool having a straight, elongate handle, such as a snow pusher, push broom, or similar tool. The extension enables the user to extend the reach of the tool for clearing large areas having only limited access thereto, as in clearing snow from a roof area from an overlooking dormer window or the like. The extension is formed of standard, off the shelf components, with a cylindrical tube handle extension and crossmember forming a T configuration. Diagonal brace straps are provided between the ends of the crossmember and a lower point on the handle extension, for better lateral strength. Additional features, such as hand grips, end caps for the tubular members, sleeves to accommodate differences in internal tube diameter and tool handle diameter, and anti-crush plugs inserted into the tubes at various attach points, may be incorporated.
