ABSTRACT:
A walker including a main frame with a main part with a telescopic frame member being slidably adjustable in relation to main part, a handle bar with a brake handle bar for activating a brake via a brake pull wire, a brake wire connected to a brake wire fastener and brake, and a brake tensioner plate arranged in frame member. The brake tensioner plate includes upper, lower and brake tensioner sheaves, one of the brake tensioner sheaves being laterally displaceable and arranged for adjusting the running length of the brake wire, so that the brake wire may be tensioned and the brake activated, for displacement along the brake wire and for telescopic displacement of the frame member, so that tensioning of the brake wire may occur independently from the vertical position of the brake tensioner plate.
