Additionally, the skids, in the vicinity of the semicircular supports, are interconnected by telescopic connectors. All devices described above have their jackets equipped with protruding supports for the person's armpits, facilitating the person's walking. The inconvenience of all known devices consists of a lack of the possibility of adjusting the height of device's vertical elements to the user's height, as well as the size of the jacket to the user's corpulence. Device for enabling persons with paresis of lower limps to walk, according to the present invention, consists of two vertical elements with handles for the user' s hands, said elements being interconnected at their upper part by a jacket with an internal frame, and being equipped with armpit supports situated at the side of said vertical elements upper ends, further said vertical elements having fixed to their lower ends skids with foot platforms, and having clamping rings for the user' s tights, fixed to said vertical elements in their lower portion, where the vertical elements consist of at least two members, being adjustable in relation to each other, the jacket consists of a three sided frame with two shorter and one longer sides, joined by corners at their respective ends, where the remaining longer side constitutes a closure, where the corners at the longer and shorter sides having respective connecting bushes, being adjustably connected with respective connecting bars, and where the closure consists of a member having at either side adjustable connectors, one of which being pivotally attached to one of the connecting bars at the shorter side of the j acket frame, the other being attachable to a lock mounted at the end of a respective connecting bar at the opposite shorter side of the jacket frame, and where the shorter sides of the jacket frame, having mounted to them, from above, two adjustable armpit supports. Said clamping rings for user' s tights are mounted to their respective connectors, which in turn are mounted adjustably and pivotally to said vertical elements. The lower ends of the vertical elements are flexibly secured into mounting bushes connected to the upper surfaces of the skids, near the middle of the skids' respective external edges, where the flexible connection constitutes a coupling of an elastic and flexible material. Additionally, to the external surface of the mounting bushes are attached the respective ends of a stabilising rod with adjustable length. Due to the adjustable members of the vertical elements, and adjustable armpit supports, as well as because of adjustable connecting bars of the jacket frame, it is possible to fit the device to the height and corpulence of the person who uses it.
