ABSTRACT:
The invention concerns a device in wheeled walker or rollator, comprising a frame member (2) having a lower end (3), a handle support rod (4) having an upper end (5), a brake-control means (6) arranged at the upper end (5) of the handle support rod, said brake-control means (6) being movable between a neutral position and a brake-application position. The rollator comprises a wheel (7) located at the lower end (3) of the frame member, the distance between said wheel (7) and the brake-control means (6) being changeable, a brake element (8) located adjacent the wheel (7), an upper force-transmission member (9) connected to said brake-control means (6), a lower force-transmission member (10) connected to said brake element (8), and a coupling means (11) for coupling-together said upper and said lower force-transmission members (9, 10). The upper force-transmission member (9) and the lower force-transmission member (10) are arranged to move freely relative to one another, when the brake-control means (6) assumes its neutral position and. The upper force-transmission member (9) and the lower force-transmission member (10) are arranged to be interconnected by means of said coupling means (11), when the brake-control means (6) leaves the neutral position, in response to which braking force is transferred to the brake element (8).
