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
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).

The invention claimed is: 1. A device in a wheeled walker or rollator, comprising at least one frame member (2) having a lower end (3), at least one handle support rod (4) having an upper end (5), a brake-control means (6) arranged essentially at the upper end (5) of the handle support rod, said br
The invention claimed is: 1. A device in a wheeled walker or rollator, comprising at least one frame member (2) having a lower end (3), at least one handle support rod (4) having an upper end (5), a brake-control means (6) arranged essentially 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, a wheel (7) located essentially 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), characterised in that 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 that 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). 2. A device as claimed in claim 1, characterised in that the upper force-transmission member (9) and the lower force-transmission member (10) are adjustable relative to one another vertically. 3. A device as claimed in claim 1, characterised in that the upper force-transmission member (9) and the lower force-transmission member (10) are adjustable relative to one another in the vertical direction, automatically and in synchrony upon any change of the distance between the wheel (7) and the brake-control means (6). 4. A device as claimed in claim 1, characterised in that the upper force-transmission member (9) and the lower force-transmission member (10) are adjustable relative to one another in the vertical direction in a stepless fashion. 5. A device as claimed in claim 1, characterised in that the transmission of force between the upper and lower force-transmission members (9, 10) is achieved by friction. 6. A device as claimed in claim 1, characterised in that the coupling means (11) is a plate allowing free passage therethrough of the lower force-transmission member (10), said coupling means (11) arranged to be frictionally locked to the lower force-transmission member (10) or, inversely, as a result of said plate assuming an oblique position relative to said latter member, when the brake-control means (6) leaves its neutral position. 7. A device as claimed in claim 6, characterised in that said plate (11) is arranged in abutment against the handle support rod (4) and in that said upper force-transmission member (9) is coupled to the plate (11) in a force-transmission fashion. 8. A device as claimed in claim 1, characterised in that the coupling means (11) is spring-biased towards its neutral position. 9. A device as claimed in claim 1, characterised in that the coupling means (11), the upper force-transmission member (9), and the lower force-transmission member (10) are at least partly accommodated inside the frame member (2) and the handle support rod (4). 10. A device as claimed in claim 1, characterised in that the lower force-transmission member (10) is in the shape of a rigid rod, at least in the area of its coupling part (15). 11. A device as claimed in claim 1, characterised in that the shape of the coupling means (11) causes it to be locked to the lower force-transmission member (10), when the brake-control means (6) leaves its neutral position.
