  • European Patent EP 1 924 489 B1 describes For example, a tricycle, which can be converted by pivoting the rear wheel about a pivot axis in the frame to a three-wheeled stroller, wherein the rear wheel of the tricycle in the driving configuration to the front wheel of the stroller is. For this conversion, however, the seat must be temporarily disconnected from the vehicle.

  • the transport wheel should be suitable in both positions as well as possible for the intended use.
  • the invention comprises a folding transport wheel with a main frame, which consists of at least two sub-frames, which are hinged together via a hinge.

  • This transport wheel is inventively characterized in that the distance between the transport device and the driven rear wheel is reduced by the folding movement from the driving position into the sliding position by the joint pivots upwards with respect to the wheel axle of the front wheels in the direction of the transport device, while the rear Sub-frame in relation to the hinge down and pivots in the direction of the front sub-frame.

  • the folding movement causes in particular that the driven rear wheel in the driving position has contact with the floor, while it has no contact with the ground in the sliding position. If the wheel is used as a bicycle, the rear wheel thus has contact with the ground and serves as the driving part of the bicycle. In the sliding position, however, it has no contact with the ground, for example, because it was raised due to the folding movement performed. Then the drive is not available, but the transport wheel in the form of a pushchair is pushed at least on the two front wheels.
  • the transport wheel may comprise means by which at least one additional wheel can be brought into contact with the ground in the sliding position. Then in the sliding position, the at least two existing front wheels and one or more additional wheels available.

  • one or more additional wheels may be attached to the transport cabin. In order to maintain contact with the ground, they can be automatically extended during the folding movement. However, there is also the possibility that the entire transport device is designed to be movable and changes its position during the folding movement. If the additional wheels are attached to this transport device, so does the position of the wheels in relation to the ground changed. Preferably, the position of the transport device with respect to the wheel axle of the front wheels is therefore variable. Then, in particular, it can be provided that the folding movement between the driving position and the sliding position causes the position of the transport device to change with respect to the wheel axle of the front wheels.

L'invention concerne un cycle de transport (10) repliable pourvu d'un cadre principal (20) constitué d'au moins deux sous-cadres (21; 22) qui sont reliés l'un à l'autre de manière repliable par l'intermédiaire d'une articulation (23). Au moins une roue arrière (32) entraînée est appliquée sur le sous-cadre arrière (22) dans le sens de la marche et au moins deux roues avant (30; 31) et un dispositif de transport (40) sont appliqués sur le sous-cadre avant (21) dans le sens de la marche. Le cycle de transport (10) peut passer par un mouvement de pliage entre une position de conduite et une position de propulsion, l'angle entre les deux sous-cadres (21; 22) dans l'articulation (23) changeant lors de mouvement de pliage. Selon l'invention, le cycle de transport (10) est caractérisé en ce que la distance entre le dispositif de transport (40) et la roue arrière (32) entraînée est réduite par le mouvement de pliage de la position de conduite dans la position de propulsion, en ce sens que l'articulation (23) pivote vers le haut en direction du dispositif de transport (40) par rapport à l'axe (52) des roues avant (30; 31), tandis que le sous-cadre arrière (22) pivote vers le bas et en direction du sous-cadre avant (21) par rapport à l'articulation (23).
