The unweighting device generally includes a standalone cage system having a rail, or a plurality of rails, allowing a user to connect thereto. The user of the unweighting system wears a harness. The harness connect to a plurality of flexible bands which connect directly to a roller subassembly. The roller subassembly, which connects to the rail or rails of the cage, allow the user to move in a lateral direction. The bands connected to the user allow the user to move in an up and down direction thereby, when combined with the rolling movement, provide for dynamic movement of the user when using the unweighting device. ## Claims ### Claim 1 An unweighting apparatus allowing a user positioned with feet on a ground level to be at least partially suspended, the apparatus comprising: at least one rail supported in a position spaced apart from the ground, the at least one rail having at least one supporting surface; a roller movably slidably connected to the at least one rail, the roller subassembly comprising: a plurality of rollers adapted to connect with and roll on said at least one supporting surface, the plurality of rollers configured to allow lateral movement along the at least one rail; a support bar connected to and hanging from the roller subassembly, the support bar configured to move rotationally with respect to the roller subassembly so as to allow the user to be at least partially suspend the body weight of a use so as to allow the user to move dynamically. ### Claim 2 (depends on 1) The unweighting apparatus of claim 1 wherein the harness includes a first portion configured to be worn on the chest of the user and a second portion configured to be worn around the waist, knees and feet of the user. ### Claim 3 (depends on 2) The unweighting apparatus of claim 2 wherein the second portion includes a knee support portion, the knee support portion including connection portions, the connection portions configured to connect to the unweighting apparatus. ### Claim 4 (depends on 2) The unweighting apparatus of claim 2 wherein a foot portion is provided connected to a knee portion, the foot portion having at least one strap configured to wrap around the bottom of the foot of the user. ### Claim 5 (depends on 1) The unweighting apparatus of claim 1 wherein the rail is connected to a frame, the frame being freestanding. ### Claim 6 (depends on 1) The unweighting apparatus of claim 1 wherein the rollers of the roller subassembly are positioned vertically so as to connect with a horizontal surface of the rail. ### Claim 7 (depends on 1) The unweighting apparatus of claim 1 wherein the rollers of the roller subassembly are positioned horizontally so as to connect with a vertical surface of the rail. ### Claim 8 (depends on 1) The unweighting apparatus of claim 1 wherein both horizontally and vertically positioned rollers are provided. ### Claim 9 An unweighting apparatus allowing a user positioned with feet on a ground level to be at least partially suspended, the apparatus comprising: at least one rail supported in a position spaced apart from the ground, the at least one rail having at least one supporting surface; a roller movably slidably connected to the at least one rail; a support bar connected to and hanging from the roller subassembly, the support bar having at least one elastic cord connected to a harness, the harness configured to be worn by the user so as to allow the user to be at least partially suspend the body weight of a use so as to allow the user to move dynamically. ### Claim 10 (depends on 9) The unweighting apparatus of claim 9 wherein the rail is connected to a frame, the frame being freestanding. ### Claim 11 (depends on 9) The unweighting apparatus of claim 9 wherein the harness includes an upper portion and a lower portion. ### Claim 12 (depends on 11) The unweighting apparatus of claim 11 wherein the upper portion is configured to securely connect to the chest of a user, the upper portion including at least 1 connection point configured to connect to a plurality of elastic cords. ### Claim 13 (depends on 11) The unweighting apparatus of claim 11 wherein the lower portion includes a belt, knee supports and foot supports. ### Claim 14 A harness for supporting a user and for connecting to an unweighting device, the harness comprising: an upper portion configured to securely connect to the chest of a user, the upper portion including at least 1 connection point configured to connect to a plurality of elastic cords; and a lower portion including a belt, knee supports and foot supports; wherein the upper portion is separate and distinct from the upper portion so as to prevent unwanted riding up of the user's clothing. ### Claim 15 (depends on 14) The harness of claim 14 wherein the foot support includes a strap configured to wrap around the bottom of the foot of the user.
