Abstract: A roller has a wheel, a wheel axle and a pin which protrudes upward from a housing of the roller. A sleeve sits on the pin and is spaced apart from the pin radially and axially upward by a damping material arranged between the sleeve and the pin, the damping material being arranged so that all axial and/or radial contact between the pin and the sleeve is prevented. Alternatively, an attachment damping part can be arranged on a pin of the roller in overlap with the pin, wherein the attachment damping part has an inner sleeve and an outer sleeve, the inner sleeve being spaced apart radially and axially upward by a damping material arranged between the inner sleeve and the outer sleeve. The damping material is arranged in such a way that all axial and/or radial contact between the inner sleeve and the outer sleeve is prevented.

Abstract: A wheel of a roller includes a roller axis, the wheel being driven by an electric motor, wherein the electric motor is a hub motor which drives a hub body, which extends with circumferential spacing and surrounds the wheel axle, relative to the fixed wheel axle, wherein furthermore the wheel has a running surface. The running surface is formed on a running surface carrier and the running surface carrier is supported flush on the hub body at the back of the running surface. Further, a manually movable load truck includes one or more rollers, of which at least one roller has a driven wheel. Further, an operating device, in particular for a manually movable load truck, is formed having a substantially annular cross-section having a central through opening.

Abstract: An additional roller has a rigid frame, with a drivable wheel which is mounted in the frame and has an axle. The wheel together with the frame can be raised or lowered by pivoting relative to a chassis, on which the additional roller is to be mounted. A compression spring is coupled rotatably at one end to the chassis, in order, in the lowered position, to load the wheel in respect of ground contact. A transverse connection connects two frame parts in the direction of an axle of the wheel. The compression spring is coupled at the other end to the transverse connection. The compression spring together with the frame pivots about the chassis-mounted pivot point during raising and lowering of the wheel.

Abstract: A hospital bed with a chassis and with four rollers arranged on the chassis has at least one further auxiliary roller that can be brought into contact with the floor or that can alternatively be driven. The auxiliary roller is mounted on a rigid frame and, together with the frame, can be raised or lowered relative to the chassis by pivoting. A drive motor is secured on the frame and drives the auxiliary roller. A separate pivot drive is provided for raising and lowering the auxiliary roller. The separate pivot drive is secured entirely on the frame and pivots with the frame.

Abstract: The invention relates to an additional roller having a rigid frame (3), with a drivable wheel (2) which is mounted in the frame (3) and has an axle (12), wherein the wheel (2) together with the frame (3) can be raised or lowered by pivoting relative to a chassis, on which the additional roller is to be mounted, and a compression spring (13) which is coupled rotatably at one end to the chassis is provided, in order, in the lowered position, to load the wheel (2) in respect of ground contact.

Abstract: The invention relates to a roller (1) having a wheel (2), which is accommodated in a housing, and a locking device (10, 17), the locking device (10, 17) being actuated by foot actuation of an actuating element (5) which is arranged so that it extends radially outwardly with respect to a vertical (V) that passes through a securing portion of the roller (1).
