DEVICE FOR THE OPTIONAL GUIDING OF AT LEAST ONE SELF-STEERING WHEEL OF A TROLLEY

摘要

The invention relates to a device for the optional guiding of at least one self-steering wheel of a trolley. According to the invention, the wheel (1) is of the type that is mounted in a support (2) that pivots around a vertical axis (V). The inventive device combines the following elements: a push bar which forms a dual-articulated steering member that can be accessed by the user; means for rotating a first clutch part (4) in relation to the vertical axis (V) in response to steering member movements; and means which can be used as desired in order to connect and disconnect the first clutch part (4) in relation to a second clutch part (5) which is solidly connected to the above-mentioned support (2) of the wheel (1), in response to other steering member movements. In addition, a coin-operated locking device for preventing the movement of the trolley is built into a case which houses a transmission element of the guiding device and which is fixed to the push bar of the trolley.
