Abstract

The invention relates to a rolling-up device comprising a tube (1) upon which a canvas (24) is attachable, the rolling-up device being arranged to be attached in two external means of attachment (16, 17), the rolling-up device further comprising a spring- controlled drive mechanism (11, 12, 13) that is tensioned when the canvas (24) of the rolling-up device is unrolled, in order to be able to roll up the canvas (24) again, the rolling-up device further comprising an inner bar (2) inside the tube (1), which inner bar (2) is arranged to be able to connect to at least one of the external means of attachment (16, 17), and the tube (1) furthermore being arranged to be rotatable about the inner bar (2), wherein a braking nut (4) that is laterally translatable inside the tube (1) and that encloses the inner bar (2) and is arranged to rotate together with the tube (1), said braking nut (4) being arranged to translate laterally along the inner bar (2) as the tube (1) rotates, the direction of the lateral translation depending on the rotary direction of the tube (1), whereby a braking action is formed from the work that is required to laterally translate the braking nut (4).
