ABSTRACT:
Attachable to and instantly detachable from a front leg of a wheel chair is a bracket component including an inclined tubular arm and an approximately semi-cylindrical upright attachment member including a lower hook portion with its open side facing away from the inclined arm and an approximately semi-cylindrical upper hook portion spaced vertically away from the lower hook portion with its open side facing toward the inclined arm and connected to the upper end of an extension thereof with a gap between said hook portions. A foot rest component has a stem telescopingly engaging and attached to the lower part of the inclined arm. To attach the device to a wheel chair leg, the operator swings the device 90 degrees so that the semi-cylindrical hook portions are horizontal, whereupon he pushes the gap between them around the wheel chair leg until the leg abuts the connecting portion between the semi-cylindrical hook portions, whereupon he swings the device back to its normal vertical position. As a result, the oppositely-facing semi-cylindrical hook portions now snugly engage opposite sides of the wheel chair leg. To prepare the wheel chair leg for the attachment of the bracket, it is only necessary for the operator to drill a pair of aligned diametral holes through the wheel chair leg and insert a stop pin, the outwardly-projecting opposite ends of which engage notches in the lower end of the lower hook portion of the attachment member. By lifting each foot rest so that its notches move away from the pin, each foot rest can then be swung horizontally inward out of the way against the adjacent side of the wheel chair or beneath it.
