Abstract
A roller board has axles provided with castors and secured at the front and rear ends of a board deck such that a steering movement is transferrable to the axles by a person on the board deck by lateral shifting of weight. Steerability and problem-free operation are improved. Substantially rigid booms, one directed to the front and one directed to the rear, are provided at the front and rear ends of the board deck, respectively. A support arm pointing in the direction of the central axis of the board deck is rigidly fastened to each boom. The support arms are pivotable on the two sides about a pivot axis inclined in the direction of travel by 40° to 50° relative to the plane of the board deck. The axle of a single castor is mounted rotatably in or on each hub, with the pivot joint inside the castor.

A roller board having an elongate board deck (1) and axles which are arranged at the front and rear ends thereof and are provided with rollers (2, 3) and are fixed steerably to the board deck (1), wherein a steering movement can be transmitted to the axles by a lateral shift in weight by the person standing on the board deck (1), wherein
- provided at the front and rear ends of the board deck (1) is a respective substantially rigid cantilever arm (4, 5) which is directed forwardly and rearwardly respectively,
- a support arm (5, 6) facing in the direction towards the centre line of the board deck (1) is rigidly fixed to each cantilever arm (4, 5),
- provided on each support arm (5, 6;
- 12) is a hub (8, 15) which is pivotable towards both sides about a pivot axis (19) which is inclined in the direction of travel through 40° to 50°, preferably through about 45°, with respect to the plane of the board deck (1), and
- the axle (17) of a single roller (2;
- 3) is mounted rotatably in or on each hub (8, 15), wherein the pivot joint (9) is in the interior of the respective roller (2;
- 3).
