  • Patent number: 4141566
    Abstract: A sled frame for the releasable attachment of a wheelchair. The sled frame includes a body portion supporting a pair of laterally spaced, horizontally disposed support members which, in turn, are sized to be disposed between the wheels of a wheelchair to support the frame of the wheelchair on the sled. The support members are each provided with a plurality of locking devices which releasably engage the frame of a wheelchair to securely lock the wheelchair to the sled. The sled frame further includes a pair of laterally spaced, longitudinally disposed ski runners. A steering runner provided at the forward end of the sled is attached to a steering post that extends upwardly through the frame and rearwardly toward the wheelchair support area such that an occupant of the wheelchair may grasp the steering wheel carried at the upper extending end of the steering post to facilitate the steering of the sled.
