The present invention relates to a rollator (1) with walking frame function, in which the rollator (1) is braked on being placed under loading. This is attained in that the rear wheels (3) are included in a wheel and brake unit, in which the wheels (3) are rotatably journalled in relation to a brake arm (11). The wheel fork (4) which supports the rear wheels (3) is pretensioned via a spring (10) to a position which holds the brake surface (12) of the brake-arm (11) at a relatively slight distance from the wheel (3). When the rollator is placed under loading, the wheel fork (4) is rotated in relation to the frame (16) of the rollator (1), the wheel (3) moving up and against the brake surface (12) of the brake-arm (11). When the loading ceases, the spring (10) moves the wheel (3) away from the brake surface (12) of the brake arm (14). |
