Abstract: A wheel fork, in particular for a jogger function of a multifunctional bicycle trailer, is provided with at least one fork arm (1, 2). A dropout (3, 4) is formed at the free end of the at least one fork arm to receive a wheel axle of a wheel (8). A system is also provided including a wheel fork and a wheel axle which interacts with the wheel fork. To provide a wheel fork which makes possible improved travel in a straight line, at least one device is provided for adjusting the wheel fork with a directional component in the direction of travel.

Abstract: A wheel fork, in particular for a jogger function of a multifunctional bicycle trailer, is provided with at least one fork arm, at the free end of which a dropout is formed to receive a wheel axle of a wheel. In one embodiment the dropout is equipped with a movable latch which can assume at least two positions, a first position where it is possible to fit the wheel axle in the dropout, and a second position where the latch blocks the opening of the dropout so that a wheel axle fitted in the dropout is held securely therein. In another embodiment the dropout is mounted on or in the tube end piece of the fork arm, such that it can be axially displaced and locked in position, so that the track of the wheel held by the wheel fork can be adjusted.

Abstract: An apparatus for securing the head and/or torso of a child by way of a belt securing system is provided. Adjustable head and torso supporting portions can be attached to the seat of a lightweight vehicle, such as a bike trailer, or an airplane.
