Caster, in particular a swivel castor, with a locking device to block the ability to run tind / or Swivel mobility dea laii

The invention relates to. One roller with a 5 ¹ Q setting device for blocking the impeller. If it is a itm Bcckrolls ;, the fixed part sur device client of the blocking of the impeller Laiifbewegliehkeit ,. In the case of a swivel castor with a pivotable running wheel, the locking device can instead or additionally be provided to block the swivel mobility of the wheel / ability of the impeller.

In such casters and especially steering rollers, the locking device includes a generally mounted in the Gabelhöhlung Blcckierungsorgan which is opposite to the blocking of the mobility of the drive wheel in a suitable way

the wheel tires are pressed on, and / or that is brought into engagement with a toothing of a fixed ball bearing shell of the roller holder for the blocking of the pivoting mobility of the impeller. The blocking device, which can consist, for example, of a stable leaf spring or a one-sided or two-sided pivot lever, can be brought into its blocking position and back into its loose "position" at will by means of an Ifaßschalt lever provided on the roller. This can be done by operating the foot switch with the carried toe _p by the pedal herunterzutreten to block the roller and raise again for the unblocking with! toe »

Raising the yuss lever again using the puss tip However, it is tedious and leads particularly to hospitals equipped with such lockable castors to damage to the light footwear of especially female hospital staff »Es have therefore already been proposed rollers with a PestStellvorrichtung, in which both the blocking as well as the subsequent blocking of the roller successive stepping down of the footshift lever can be achieved «For this purpose, the Roller fork a equipped with a ratchet wheel j; oval or polygonal swing arm pivoted, the du3? ch || Stepping down the shift lever by one shift j: sjahn wait can be turned and they take turns on the blocking organ stored in the .Gabelhöhlung. has a blocking effect or releases it again *

In the event of an axial displacement of the pressure pin 24b, the point at which the transverse groove 52 of the pressure pin 24 intersects with the curved control path 50 of the fixed sleeve 51 changes. In the movable curling point of the two hats 50 and 52, a ball 53 is freely movably arranged as a locking body engages in the transverse groove 52 of the axially movable pressure pin 24b. The point of intersection of the two hats 50 and 52 thus forms the bearing housing encompassing the ball 53 on all sides, which cannot leave the freely movable ball 53. When the pressure pin 24b is axially displaced, the ball 53 is thus forced to join the movable intersection point of the Hats 50 and 52 unrolling with the wandera, whereby the ball 53 can be guided through the transverse groove 52 into one or more locking positions and locking positions of the control path 50 when the pressure pin 24b is repeatedly actuated and released, so that the backward movement of the pressure pin can thereby be guided 24b is alternately blocked or released *
