Abstract: The steering assembly is applicable to a human-driven vehicle having a chassis (1) mounted on self-orienting wheels (2). The steering assembly comprises a steering unit (50b) with a steering wheel (4) installed on a mobile support and maintained out of contact with the ground by elastic means at an end (1b) of the chassis (1), and a control unit (50a) with a command member (7) in another end of the chassis. The units are connected by transmission devices (19, 20, 21). The command member (7) is manually operable to lower the steering wheel (4) against the force of said elastic means and to make the steering wheel (4) rotate with respect to a substantially vertical shaft when the wheel (5) is in contact with the ground to steer the vehicle. The elastic means automatically lift the steering wheel (4) when the manual operation of the command member (7) ceases.

Abstract: 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 is of the type that is mounted on a support that pivots around a vertical axis. The device comprises: a push bar which forms a dual-articulated steering member that can be accessed by the user; means for rotating a first clutch part about the vertical axis in response to steering member movements; and means which can be used at will to couple and uncouple the first clutch part in relation to a second clutch part which is solidly connected to the aforementioned support of the wheel, 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 casing which houses a transmission element of the guiding device and which is fixed to the push bar of the trolley.
