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: The invention relates to a roller (1), preferably comprising two wheels (2) and a locking device, an activating part (10) acting on the locking device for releasing or locking, and the activating part (10) being movable by a drive, a movement of a transmission part (7) that is generated by the drive being transmitted via spring force to the activating part (10) for moving same, and a spring (8) being supported on the transmission part. In order to provide a roller that allows an advantageous constructional design, it is proposed that a support region is formed for the spring (8) and/or the spring (9) and/or the compression spring (44) on the activating part (10), through which region the transmission part (7) can pass.

Abstract: The invention relates to a mounting plate (4) which is placeable on a fork (3) or a rotary bearing of a caster (1) and which is connectable to the fork (3) or to a part of the rotary bearing (43), the invention also relating to a caster (1) comprising a fork (3) and/or a rotary bearing (43), and also a wheel (2), and a mounting plate (4) that is disposed at the upper side of the fork (4) and/or the rotary bearing (43), as well as a caster (1) comprising a wheel (2) and a fork (3), the fork (3) being rotatable relative to a locking part (33) about a vertical axis (A), and a first spring part (21) that is fixed to the fork being provided for interacting with the locking part (33) with regard to rotational locking.

Abstract: The invention relates to a roller (1), preferably comprising two wheels (2) and a locking device, an activating part (10) being able to act on the locking device for releasing or locking in a position that corresponds to a directional lock and/or in a position that corresponds to a total lock, and the activating part (10) being movable by a drive, a linear movement of a transmission part (7) that is generated by the drive being transmitted via spring force to the activating part (10) in order to move the activating part, and the activating part (10), in any case in a position corresponding to the total lock or in any case in a position corresponding to the direction lock, being in addition movable relative to the stationary transmission part, against a spring supported on the transmission part, into a release position by means of an actuating handle (11) that is movable independently of the drive and preferably by hand so as to override the total lock or the directional lock.
