MOBILITY DEVICE

Abstract

A garment attachable to an exercise or therapeutic apparatus that is capable of elevating the user slightly above the ground, reducing potential for injury and strain by shifting the user's weight to the frame of the apparatus. The garment is incorporated into the apparatus by comprising panels under the buttocks and around the thighs, providing balance and lifting the user comfortably in conjunction with the frame. A low-friction plate is positioned under the user's feet so that the user can ambulate freely while held in place by the frame.

DETAILED DESCRIPTION

[0016] An example of an exercise apparatus is depicted in FIG. 2. Support ring 21 surrounds a user 11 at waist level and is vertically movable by hinges 21 and 23. With reference to FIGS. 1A through 1C, garment 1 wearable by user comprises a posterior band 4, a left leg anterior band 8, and a right leg anterior band 7. Garment 1 is attachable to support ring 21 such that lifting the support ring suspends the user above the ground. The user is lifted and fixed in place by the support ring, but elasticity of the garment allows ambulatory movement. Because the combination of the garment and frame bear the user's weight, the user moves without strain on the lower body.

[0017] FIG. 2 shows a friction-adjustable plate 30 positioned under the user's feet. Because the friction of the pad 30 is adjustable, resistance can be added or subtracted to change the way the user's feet slide over the pad. The friction-adjustable plate comprises a low-friction surface, such as a surface that has been coated with dry film lubricant, wherein friction can be increased by the introduction of a high-friction material such as rubber or felt. A cloth foot garment may further decrease the coefficient of friction between the user's feet and the friction-adjustable plate. An example of a friction-adjustable plate is shown in FIG. 4, comprising a first layer 33 with openings 31 and a high-friction section 33, and a second layer 36 with high-friction sections 35 and low-friction section 36. The second layer 36 is slidable under the first layer 33 such that the high-friction section can be exposed through openings 31. Increasing the level of exposure of the low-friction section 36 through openings 31 results in increasing the resistance against the user's feet, while exposing only the high-friction section 35 results in decreasing resistance. An alternative to the two-layer friction-adjustable plate is a single-layer friction-adjustable plate comprising a low-friction material and vertical strips of high-friction material, such that rotating the plate results in increasing the amount of friction against the user's feet.

[0018] An example of the attachable garment 1 is shown in three views in FIGS. 1A through 1C. The garment 1 comprises a posterior band 4, a left leg anterior band 8, and a right leg anterior band 7. The posterior band 4 lifts the user's posterior from the front side of the user's waist, extending from under the buttocks to the user's front, where the posterior band 4 can be attached to the support ring 21. The anterior bands 7 and 8 extend from the user's right and left front thigh to the back side of the user's waist, where the anterior bands 7 and 8 are attachable to the support ring 21. The posterior and anterior bands counterbalance each other, due to the fact that they extend from the front of the frame to the back of the user, and the back of the frame to the front of the user, criss-crossing at the user's side. The user's center of gravity is maintained above the ground and the user does not tip forward or backwards when elevated off the ground by the frame. Furthermore, because the bands are less elastic than the rest of the garment, their attachment to the frame creates a structure that lifts the user from the garment itself, distributing the user's weight to the frame evenly and comfortably.

[0019] Right and left anterior bands 7 and 8 are securable around the leg via right and left braces 2 and 3, respectively. Braces 2 and 3 are coupled to anterior bands 7 and 8, respectively, such that when the garment is attached to the frame, the user is lifted by the anterior bands pulling the user up from the braces. By hoisting the user by the thighs and the user's weight being distributed to the frame via the bands, pressure is alleviated from the crotch, which would typically receive the force of the garment as the garment is hoisted by the frame. Moreover, the right and left braces 2 and 3 may be adjustable to accurately fit the user and to allow the user to adjust for comfort. The braces may be adjustable according to many forms currently known in the art, such as by Velcro as depicted in FIGS. 1A through 1C.

[0020] In the preferred embodiment, the garment 1 comprises a cloth or cloth-like fabric that is elastic to allow the user full range of movement. The posterior 4 and/or anterior bands 7 and 8 comprise a less elastic material than the rest of the garment 1, to facilitate weight distribution. For instance, one or more of the posterior and anterior bands may be comprised of materials such as limited-stretch polyester or nylon. Posterior and/or anterior bands may be comprised of a denser weave than the rest of the garment 1, or the bands may be reinforced with a less elastic material, or the bands may be sewn into the rest of the garment.

[0021] The garment may be attachable to the frame by a variety of known means suitable for hoisting human weight, such as hooks, carabiners, and cam buckles. In the example depicted in FIGS. 1 through 3, posterior band 4 is attachable at the front section of ring 21 at attachment points 25 and 27, anterior band 7 is attachable at the rear section of ring 21 at attachment point 26, and anterior band 8 is attachable at the rear section of ring 21 at attachment point 24. Ring 21 surrounds the user at waist level, and is vertically movable such that the user 11 is lifted by the garment attached to ring 21.

[0022] The frame is vertically movable to suspend the user off of the ground, and lowerable to allow the user to step into the ring 21 with minimal effort. For instance, hinges 22 and 23 can be used to raise and lower the front and rear legs of the frame. In the preferred embodiment, the frame is collapsible as depicted in FIGS. 3A and 3B. A right ring support 53 is rotatably connected by pin connection 47 to the right leg 51 of frame 20, while left ring support 54 is rotatably connected by pin connection 48 to the left leg 52 of frame 20, such that frame 20 is vertically movable by rotation of the supports and legs in their pin connections. By forcing frame 20 away from the right and left ring supports 53 and 54, actuator rods 45 and 46 rotate the supports and legs in their pin connections to vertically move support ring 21. The actuator rods 45 and 46 can be operated manually using rotatable knobs 28 and 29, as depicted, or they can automatically operated. Electronic control unit 39 may be used to facilitate automatic operation of the frame.

[0023] The frame is elevatable to fully suspend the user off of the ground such that the user can walk or run over the ground with less joint and muscle strain. As such, the frame only needs to be capable of suspending the user up to 5 inches off of the ground. The low-friction surface 30 allows the user to ambulate in place within a stationary frame, but the frame 20 may also comprise a front and rear wheel such that the user can push against the ground and move with the wheeled frame with reduced body weight on the user's legs.
