Abstract:
A rolling aid for use by elderly people and disabled people, comprising a frame provided with handle bars, said frame comprisinga first and a second pair of frame bars or frame tubes which extend, in a rolling position, obliquely forwardly and rearwardly respectively with respect to a rolling (walking) direction and are provided at their lower ends with wheels, and a first upper and second lower foldable transverse connection between each two frame tubes forming a pair, which allow said pairs of frame tubes to be folded in a transverse direction with respect to said rolling (walking) direction, whereas said pairs are connected to one another in such a way, that they may be folded together about a transversely directed axis, wherein said first upper foldable transverse connection is formed as a foldable or hinge joint platform which takes, in the rolling position, a stretched position in a substantially horizontal plane, halves of said platform being pivotally connected in a vertical plane of symmetry of said aid and being each pivotally mounted to said frame tubes on a respective side of said aid for an upward folding movement, whereas said second lower foldable transverse connection is formed by a plurality of hinge bars provided on a lower level with respect to said platform of said upper foldable transverse connection, which connect said frame tubes of said first pair, which tubes extend upwardly beyond said stretched platform up to handle bar level, and a space between said obliquely downwardly extending frame tubes of said second pair, which, at the level of said stretched platform, deviate substantially horizontally towards said first pair of frame tubes, is free from transverse connections, wherein said platform halves are each hingedly connected to a frame tube of said first pair that extend, in an unfolded position, upwardly beyond said stretched platform and that tube sections of said frame tubes of said second pair which deviate, in the rolling position, substantially horizontally, are each directed from a location at a corner of said stretched platform on a respective side of said aid obliquely inwardly towards a connecting point at an opposite transverse edge of said platform, said respective side of said aid obliquely deviating tube sections being mounted to said respective platform halves for a rotary movement about their axes relative to said platform halves, while said tube sections of said frame tubes of said second pair which deviate, in the rolling position, substantially horizontally, are being prevented from turning about their axes relative to one another, said plurality of hinge bars of said second foldable transverse connection being, on one hand, exclusively connected to said frame tubes of said first pair and, on the other hand, directly connected to said platform.
