Wheelchair accessory
Abstract:
My invention is an improvement upon the previously existing wheelchair warning lamp apparatus that fails to allow the wheelchair to fold and be used indoors when installed onto the wheelchair and require drilling to be installed. My apparatus, a clamp-on extendible and retractable cylinder shaped erected pole has a safety light and an audible alert equipment installed on top of the inner casing and a pole lock nut installed on the outer casing whereas the outer pole casing is attached to the battery housing support member with three C-Clamps vertically and horizontally attached on the battery housing allowing the pole and battery safety light assembly with audible alert apparatus to be clamped onto one side only of the wheelchair without drilling required and allows the chair to fold and be used indoors without removal of the installed pole and battery with safety light with audible alert apparatus from the wheelchair.
