ABSTRACT:
In a preferred embodiment, a self-returning hinge is embodied in an appliance or tool comprising a tubular handle and an open frame formed from a flexible spring metal into a desired shape and having a pair of U-shaped end sections extending laterally outwardly therefrom in mutually overlying relation into a hollow end section of the handle which is crimped along one side thereof with the opposite side being flattened to retain the U-shaped end sections therein in such overlying relation. Various elements such as nets, brushes, and scrapers may be attached to the frame as desired.
Other embodiments which do not provide a self-returning hinge are also described; however, such embodiments do provide certain other advantages also associated with the preferred embodiment. In one other embodiment, the frame is made from a non-spring metal and in a second other embodiment, the referenced hollow end section is crimped along two opposing sides and the frame is made from a non-spring metal.
