Abstract: A mobility aid, comprising a first frame member, a second frame member, and at least one pivoting member, which is connected to the first frame member and is pivotably mounted about a pivot axis to the second frame member. The pivoting member can be moved into a use position and into a transport position relative to the second frame member. A first locking device locks the pivoting member relative to the second frame member whenever the pivoting member is in the use position. A second locking device locks the first frame member relative to the second frame member whenever the pivoting member is in the transport position.

Abstract: A collapsible mobility aid with two frame elements, on each of which at least one wheel is secured or can be secured, and with a folding mechanism by which the frame elements are connected to each other, and a distance between the frame elements in a first position of the folding mechanism can be adapted to a transport distance and in a second position of the folding mechanism can be adapted to a use distance, wherein the folding mechanism has a central element with a slide arranged moveably with respect thereto, at least two connection arms which are each articulated on a frame element and on the central element, and at least two levers which are each articulated on a connection arm and on the slide, wherein the swivel axes, about which the levers are arranged on the connection arms and the slide such that they can be swiveled, are on one plane when the folding mechanism is in the second position.
