Abstract

A wheelchair latching device designed to connect a wheelchair to a commode, which latching device includes a latch mechanism mounted on the wheelchair and designed to engage a receiver mechanism secured to the floor and/or the commode. An axle component of the latch mechanism is designed to engage a pivoting latch tongue provided in the receiver mechanism to releasably secure the axle against a pair of spring-loaded tension receivers which are forced rearwardly in the receiver mechanism housing responsive to impact with the axle when the axle engages the latch tongue. The axle is thusly locked between the tension receivers and a lip provided on the latch tongue, and the seat of the wheelchair is thereby securely positioned immediately adjacent to the commode seat. Release of the wheelchair from close proximity to the commode is effected by hand-operation of a cable which activates a release provided in the latch mechanism and release the axle from engagement with the latch tongue and the tension receivers located in the receiver mechanism.
