<p>A full body weight traction device for rotating a human into inverted posture comprising generally U-shaped front and rear legs with the bases of the U-shapes resting on the floor and having upstanding sides terminating in pivot bearings, a shorter U-shaped trunion having upstanding sides also terminating in pivot bearings and having the base of its U attached to a tilt bed including a human torso supporting means and an elongated rail extending between the ankles of a user. The respective pivot bearings on each side of the front and rear legs and the trunion are pivotally connected by a pivot pin, permitting rotation of the tilt bed and folding of the legs for storage. The rail is provided with a hinge and lock which permits the rail to fold against the torso supporting means, whereby the tilt bed and legs fold into a configuration about the same length as the legs. The spacing of the sides of the rear leg is greater than the width of the tilt bed and the spacing of the sides of the front legs is less than the width of the tilt bed, whereby rotation of the tilt bed is stopped in the inverted position by the front leg sides. The footprint of the base of at least one of the U-shaped legs is increased by a stabilizer means.</p> |
