Abstract: An accessory holder for a wheelchair is selectively mountable on a wheelchair of the type having no arm rests. The mount includes a base that fits over a lower frame member of the wheelchair. A support rod is fixed to the base and extends up, to terminate in the accessory holder. A latch is fixed to an upper frame member of the wheelchair and receives and holds the support rod. The support rod must move up to release the base from the lower frame member, and a stop on the rod prevents upward movement when the rod is held by the latch. Many different accessory holders may be carried by the support rod, and the accessory holders are interchangeable with respect to one wheelchair.

Abstract: A lock for a retainer pin prevents accidental opening of the ring of the retainer pin. A body has an elongated slot receiving the ring of a retainer pin, with a detent to inhibit motion of the body on the ring. A bore in the body is alignable with the pin of the retainer pin. The bore has an open portion that allows free movement away from the pin, and a closed portion that prevents movement away from the pin. The retainer pin may have a colored portion that is outside the bore when the pin is received only in the open portion of the bore, and is inside the bore when the pin is received in the closed portion of the bore.

Abstract: A tray holder is provided for a wheelchair, whereby the tray holder can be conveniently stowed beneath an arm rest with no tray. The tray holder is carried by an arm pivotally carried from one of the vertical supports of the chair, so the tray holder can be disposed in front of the chair or at the side of the chair. When there is a tray in the tray holder, the tray can be at the front or side in useable condition. In another form of the device, the tray holder is held by the arm rests themselves, and the tray provides the force to maintain engagement with the chair.
