Abstract
A multiple terrain mobility device capable of use as a walker or crutches. The mobility device has a central cross support and a pair of crutch assemblies. Each respective crutch assembly has a rear support leg that can be extended downward or retracted upward and a front leg assembly that is capable of extending forward or retracting rearward. These adjustable extension features allow the mobility device, to traverse terrain of varying height such as stairs or hills with greater stability. The central cross support can be separated into a left and right cross support member so that the walker can be converted into a pair of crutches when conditions warrant.
Claims18
A multiple terrain mobility device comprised of a central cross support and a pair of crutch assemblies,
- wherein each respective crutch assembly is comprised of a set of support legs which include at least one vertically oriented front support leg and at least one vertically oriented rear support leg and at least a pair of horizontally oriented components,
- wherein each respective rear support leg is rearward of the respective front support leg relative to the position of a user of the mobility device facing forward,
- wherein the respective front and rear support legs are secured by, and help secure, the at least a pair of horizontally oriented components,
- wherein the at least a pair of horizontally oriented components are comprised of a top hand grip that extends from the front support leg to the rear support leg,
- at least one center crutch handle, also extending from the front support leg to the rear support leg, and is connected to the front and rear support legs in a relative position beneath the top hand grip,
- and at least one bottom support bar also extending from the front to the rear support leg in a relative position beneath the at least one center crutch handle,
- and wherein the rear support leg further comprises adjustment apparatus capable of extending the rear leg downward or retracting the rear leg upward to adjust a height of the rear leg, and
- further comprised of an extendable or retractable front leg component connected to the at least one bottom support bar in a relative forward direction from the front support leg, and
- and further comprised of a front leg adjustment apparatus for retracting the front leg component or extending the front leg component in horizontal or vertical directions to provide extra horizontal and vertical stability and
- wherein the central cross support is further comprised of a left cross support member and a right cross support member relative to a user,
- and a separation apparatus that is capable of both securely holding the left and right support members together and reversibly separating them, located in proximity to an area between the left and right cross support members,
- and wherein the rear leg adjustment apparatus is comprised of either a motor with a controlling device or a detent adjustment apparatus,
- and is further comprised of an extension controller capable of retracting or extending the rear leg.
