  • Patent number: 4749160
    Abstract: The double-circle utility holder of the present invention, characterized primarily by its holder body being provided with two circular clamp portions, one at the top and the other at the bottom. In the center of each clamp portion there is a holding hole, with a frictional rubber washer attached thereto. The holder is made of elastic material. Owing to the elasticity of the material, the holder can be bent till the two clamp portions are almost in contact with each other so that the round rod handle of the tool can pass through the holes of the clamp portions, and when the bending force is released, the clamp portions hold the handle of the tool firmly by the friction exerted thereon by the rubber washer. In addition, the back of the holder is provided with a slider on an opening in its central portion so that the holder can slide on a rail or is individually secured to a wall.
