The upper part has at least four, and preferably five, bends and includes a manually graspable handle portion between two of the bends, and a hook-shaped bend for engaging the user's forearm on three sides adjacent the elbow. An intermediate portion including another bend is positioned between two other bends, and is positioned between the handle portion and the bend located adjacent the user's elbow. The lower part includes a floor-engaging free end and defines an axis, preferably a generally vertical axis. The bends and other features of the upper part cooperate to provide improved support for a user's forearm. Also disclosed is a rocker-type end member either fixedly or slidably fitted to the lower part. ## Claims ### Claim 1 A mobility device for providing ambulatory support for a user, comprising: a tubular body having an upper part and a lower part, the upper part having at least five spaced-apart bends and terminating in a free end; a U-shaped forearm engaging portion adjacent the free end comprising one of said bends; a manually graspable handle portion disposed between two of said bends, an anterior bend curving downward toward the lower part and a posterior bend curving upward toward the free end, the handle portion defining a vertical plane that includes an axis of the user's forearm when the user's hand grasps the handle portion and the user's forearm is placed in the U-shaped forearm engaging portion; a generally S-shaped intermediate portion extending from the posterior bend between the handle portion and the U-shaped forearm engaging portion; and the lower part defining an axis extending substantially in the vertical plane and including a floor-engaging free end. ### Claim 2 (depends on 1) The device of claim 1 wherein at least three of the five bends support and guide the forearm of the user, limiting excursion of the user's forearm away from the vertical plane, so as to maintain approximate alignment of the axis with the vertical plane. ### Claim 3 (depends on 1) The device of claim 1 wherein the upper and the lower parts are movable toward and away from one another. ### Claim 4 (depends on 1) The device of claim 1 wherein the upper part is telescopically movable with respect to the lower part. ### Claim 5 (depends on 4) The device of claim 4 further wherein the first and the second interengaging parts cooperate to define a detent for selectable adjustable positioning of one part inside the other. ### Claim 6 (depends on 1) The device of claim 1 wherein each of the five bends is a single plane bend. ### Claim 7 (depends on 1) The device of claim 1 further comprising a rocker member at the floor-engaging free end, having a convex downwardly facing surface. ### Claim 8 (depends on 7) The device of claim 7 wherein the rocker member is slidably mounted to the floor-engaging free end. ### Claim 9 (depends on 1) The device of claim 1 wherein: the U-shaped forearm engaging portion is downward slanting with the one of said bends disposed between a pair of legs, with each of the legs being substantially similar in length. ### Claim 10 A mobility device for providing ambulatory support for a user, comprising: a tubular body having an upper part interengaged with a lower part, the lower part defining an axis and the upper part having at least five spaced-apart bends and terminating in a free end; a manually graspable handle portion disposed between two of said bends, an anterior bend curving downward toward the lower part and a posterior bend curving upward toward the free end; a downward slanting U-shaped forearm engaging portion adjacent the free end comprising one of said bends disposed between a pair of legs, with each of the legs being substantially similar in length; and an intermediate portion extending from the posterior bend between the handle portion and the U-shaped forearm engaging portion; wherein the manually graspable handle portion is disposed above, and intersecting the axis of the lower part. ### Claim 11 (depends on 10) The device of claim 10 wherein the device is configured to be used interchangeably, without modification, in either of the user's right and left arms. ### Claim 12 (depends on 10) The device of claim 10 wherein at least three of the five bends support and guide the forearm of the user, limiting excursion of the user's forearm away from the axis of the lower part, so as to maintain approximate alignment therewith. ### Claim 13 (depends on 10) The device of claim 10 wherein the upper and the lower parts are movable toward and away from one another. ### Claim 14 (depends on 10) The device of claim 10 wherein the upper part is telescopically movable with respect to the lower part. ### Claim 15 (depends on 10) The device of claim 10 further comprising a rocker member at the floor-engaging free end, having a convex downwardly facing surface. ### Claim 16 (depends on 10) The device of claim 10 wherein the rocker member is slidably mounted to the floor-engaging free end. ### Claim 17 A mobility device for providing ambulatory support for a user, comprising: a tubular body having an upper part and a lower part; the upper part having at least five bends defining a vertical plane and terminating in a free end, the lower part defining an axis in the vertical plane; the upper part comprising a downward slanting U-shaped forearm engaging portion adjacent the free end, the U-shaped forearm engaging portion comprising one of the bends disposed between a pair of legs, the legs being substantially similar in length; the bends cooperating to orient an axis of the user's forearm in substantial alignment with the vertical plane; and the lower part having a floor-engaging free end. ### Claim 18 (depends on 17) The device of claim 17 wherein the upper part and the lower part are telescopically engageable one in the other. ### Claim 19 (depends on 17) The device of claim 17 wherein the upper and the lower parts form portions of a one-piece monolithic body member. ### Claim 20 (depends on 17) The device of claim 17 further comprising a rocker member at the floor-engaging free end, having a convex downwardly facing surface. ### Claim 21 (depends on 20) The device of claim 20 wherein the rocker member is slidably mounted to the floor-engaging free end. ### Claim 22 A mobility device for providing ambulatory support for a user, comprising: a tubular body having an upper part and a lower part, the upper part having at least four spaced-apart bends and terminating in a free end; a U-shaped forearm engaging portion adjacent the free end comprising one of said bends; a manually graspable handle portion disposed between two of said bends, an anterior bend curving downward toward the lower part and a posterior bend curving upward toward the free end, the handle portion defining a vertical plane that includes an axis of the user's forearm when the user's hand grasps the handle portion and the user's forearm is placed in the U-shaped forearm engaging portion; a generally S-shaped intermediate portion extending from the posterior bend between the handle portion and the U-shaped forearm engaging portion; and the lower part defining an axis extending substantially in the vertical plane and including a floor-engaging free end. ### Claim 23 (depends on 22) The device of claim 22 wherein at least three of the four bends support and guide the forearm of the user, limiting excursion of the user's forearm away from the vertical plane, so as to maintain approximate alignment of the axis with the vertical plane. ### Claim 24 (depends on 22) The device of claim 22 wherein the upper and the lower parts are movable toward and away from one another. ### Claim 25 (depends on 22) The device of claim 22 wherein the upper part is telescopically movable with respect to the lower part. ### Claim 26 (depends on 25) The device of claim 25 further wherein the first and the second interengaging parts cooperate to define a detent for selectable adjustable positioning of one part inside the other. ### Claim 27 (depends on 22) The device of claim 22 wherein each of the four bends is a single plane bend. ### Claim 28 (depends on 22) The device of claim 22 further comprising a rocker member at the floor-engaging free end, having a convex downwardly facing surface. ### Claim 29 (depends on 22) The device of claim 22 wherein the rocker member is slidably mounted to the floor-engaging free end.
