  • Patent number: 4449750
    Abstract: Container accessories are configured for removable securement to mobility aids such as walkers, wheelchairs or the like with tubular frame members. Each accessory includes a framework and panel members supported by the framework to define at least one compartment, the framework being self-supporting. Both the framework and panel members are of strong, lightweight material, e.g., aluminum. Resilient spring clips are carried by the framework at locations thereon for supporting the framework from the frame members of the aid by engaging its tubular frame members. For use with a walker, the accessory is preferably multiply compartmented and engages a cross member of the walker. For use with wheelchairs, frame components of the accessory framework are adjustable and reconfigurable to permit engagement of arm support members of the wheelchair, even though of different possible frame configurations, at the front or at the side of the wheelchair.

  • Patent number: 4266825
    Abstract: A mounting device of the described type may be viewed as being somewhat similar to a camera tripod, for example. Four extendible legs are adapted to be secured to the arms of a wheelchair. Two of the legs terminate in flat pad mounts which may be attached to and rest upon the upper broad and flat surfaces of wheelchair arms. The other two legs include interchangeable ends, some of which may also include flat pad mounts to be attached to the flat surfaces of such arms, and others of which may include spring-clips that may be snapped over or clamped around a bar with a circular cross section. The flat pads are preferably held in place by straps using "Velcro" hook and loop fasteners. The spring-clips are primarily devices which may be pushed into place around a circumference of a circular pipe. Optionally, a wing nut may supplement the circular clamps to more securely hold them in place.
