  • Wheelchair swivel platform
    Patent number: 6568646
    Abstract: A wheelchair swivel platform that allows a standard, unmodified wheelchair or other non-swiveling chair and an occupant to swivel about an area of a workstation, in much the same way as a modem swivel office chair. The wheelchair swivel platform includes a top plate 16 and a bottom plate. The bottom plate serves as a base for the platform which lies on the floor to support the top plate 16. The top plate 16 swivels about the bottom plate while supporting the wheelchair. A rotation locking device prevents rotation of the platform during positioning of the wheelchair on and off the platform.
