Abstract:
A wheel-chair for disabled people adapted to be reduced and obtained by assembling single parts, some of them being modular, without requiring heat welding, said wheel-chair comprising:two side frames, each one of said side frames being composed of a structure formed by front and rear risers and upper and lower iron girders joined together through mechanical fastening means;an articulated cross including rods that are hinged together, said rods being integral with tubular cross members at upper and lower ends thereof;two brackets supported by said front risers, said brackets supporting rods having lower ends that are equipped with foot rest boards, said brackets being movable and separable from said front risers by rotating said brackets outwards;two stakes applied to said rear risers to support a back, said stakes being able to project above said back in order to provide handles for a person to drive said wheel-chair;two side boards with arm-rests;two pairs of front and rear wheels, said rear wheels being adapted to be equipped with hand rings for a user to drive said wheel-chair; anda device to brake said wheels;wherein said front risers each comprise upper and lower portions and a cylindrical post extending therebetween, the cylindrical post has a pair of opposed flat faces which are parallel and define therebetween a width less than the diameter of the cylindrical post, and said upper and lower portions have opposed surfaces spaced apart to receive therebetween a corresponding one of said brackets to prevent vertical shifting movement of the bracket when the bracket is assembled to the riser, andwherein said brackets each include a holder portion comprising a channel which opens to a side of the holder portion to define a slot having a width narrower than the diameter of the cylindrical post and wider than the width of the post between the opposed flat faces, and said channel having a diameter corresponding to the diameter of the post, such that said post can be inserted into said channel when the slot is aligned with the width of the post defined between the opposed flat faces and then rotated to lock the bracket to said post, whereby coupling/uncoupling of the foot-rest boards with respect to the wheel-chair is made possible by solely rotating the brackets inwards/outwards without the need of any vertical movement of the brackets.
