A portable lumbar traction device wherein a variable tension system allows the user to manually manipulate a level of tension using a ratcheting device while undergoing a traction procedure. The invention easily and quickly anchors to a door frame and includes one or more springs to create tension in the device. A belt or harness worn by the user couples to a cable or tether in tension with the spring, and the ratcheting device incrementally increases the tension when actuated by the user until the desired tension level is achieved.

I claim: 1. A portable lumbar traction device adapted to work on a floor and with a door and door fame comprising: a tubular anchor having a diameter larger than a distance between said door and said floor when said door is closed; a tether having first and second ends, said first end connected to said tubular anchor, said tether adapted to pass under said closed door and having a length such that said second end is spaced from said closed door; a spring having first and second ends, said first end of said spring connected to said second end of said tether; a belt worn by a patient having straps for applying a traction to said patient when said straps are placed in tension; and a tension advancing mechanism comprising: a weighted platform having an upper and lower planar surfaces, said lower planar surface in contact with said floor during operation of said portable lumbar traction device and said upper planar surface supporting a ratchet thereon, said weighted platform disposed directly between said spring and said belt; a ratchet pivotally mounted to said weighted platform on said upper surface and engaging a distal end of straps of said belt for incrementally advancing said straps; an actuator lever having first and second ends and extending radially outward from said pivotally mounted ratchet, said actuator lever connected to said ratchet at said first end and said second end including an aperture for engaging a pole; and a pole adapted to engage said second end of said actuator lever at said aperture to rotate said ratchet and reduce a length of strap between said belt and said ratchet. 2. The portable lumbar traction device of claim 1 further comprising a display for showing a tension developed in the device. 3. The portable lumbar traction device of claim 1 further comprising a strain gauge. 4. The portable lumbar traction device of claim 1 further comprising a chest belt cooperating with a mat to resist slippage between a user and the floor.
