Abstract
The present invention relates to a caster (1), in particular a steering roller having a wheel (5, 6) and a locking device, the locking device having a setting element (7) and engagement element (9) which cooperates with the setting element so as to block the travel of the wheel (5, 6) in which a linear setting movement of the setting part (7) can be transmitted via a wedge transmission (10) to the engagement element (9). In order to achieve a development which is as simple as possible from a design standpoint and also has advantageous kinematics, the invention proposes that the engagement element 9 be arranged guided for linear movement in order to effect a linear engagement movement with respect to the wheel (5, 6).
Claims13
A caster comprising:
- a rotation shaft and a travel wheel mounted on the rotation shaft;
- a locking device having an engagement element positioned adjacent the wheel for releasable engagement with the wheel, the locking device further comprising a setting element for placing the engagement element into a position of engagement with the wheel to block a traveling of the wheel;
- wherein the locking device includes means for translating a linear setting movement o the setting element into a linear movement of engagement of the engagement element;
- the engagement element is moveable in a direction transverse to an axis of rotation of the wheel for engagement with an inner surface of the wheel, the inner surface facing away from the travel surface of the wheel and extending substantially perpendicular to a plane of rotation of the travel wheel;
- and
- the engagement element is lockable in a blocking position between the setting element and the wheel.
