Abstract
A foldable walking-assistant device with which the handle's height can be properly adjusted according to the user's height. The device itself can be used as a chair. Moreover, the device can be folded and unfolded easily by the one-touch manner. A left and right leg body each consist essentially of the horizontal leg whose longitudinal length can be adjustable, the handle pipe which is vertically placed on the horizontal leg and is adjustable as to the height of the device, and the rear pipe which is provided at the handle pipe. The leg body possesses the folding mechanism combined with the associated action of the cross bar. The hand brake is installed at the handle pipe.
Claims7
A foldable walking-assistant device comprising a horizontal expandable pipe which consists of a short-span pipe and a long-span pipe wherein the latter is inserted slidably inside of said short-span pipe in the horizontal direction;
- a pair of front and back fixture pipes which are vertically mounted onto the short-span pipe of the expandable pipe;
- and a handle pipe which is inserted slidably inside the first fixture pipe in a vertical direction and the upper portion of the front side pipe is connected to the upper portion of a back side movable pipe that is inserted slidably inside the back fixture pipe, said upper portion being in a form of a T-shape,
- an expandable vertical leg post and an L-shaped rear pipe which is connected to a back side of the vertical leg post and angled slightly outwardly of the horizontal expandable pipe,
- a connecting arm for reinforcement purpose between the L-shaped rear pipe and the back side of the vertical leg post,
- a pair of left and right horizontal legs in which casters are installed, and disposed at the front end portion of the long-span pipe and at the lower end portion of the L-shaped rear pipe through a horizontal cross pipe in which two pipes are inter-crossed horizontally in an X-shape and one end thereof is connected to the front end portion of the short-span pipe and the other end is connected to the back end portion of the long-span pipe,
- a vertical cross pipe which is connected foldably between the handle pipes which are vertically placed relative to the pair of left and right short-span pipes through an arm in which two pipes are inter-crossed vertically in an X-shape and one end thereof is pivoted rotatably vertically to a root portion of the front side of the fixture pipe and the other end is pivoted rotatably vertically to the upper portion of the front side of the fixture pipe,
- a vertically foldable seat-receiving component pivotally mounted to a seat pipe which is horizontally mounted to the front and back fixture pipes and above the horizontal leg,
- a seat detachably mounted to the aforementioned seat-receiving component, and
- a rear-wheel controlling system including a hand brake mounted onto the handle pipe.
