  • Caster comprising a running wheel
    Patent number: 11247509
    Abstract: A caster includes a running wheel, a fork and an assembly journal, wherein the fork is pivotable in relation to the assembly journal and a braking device is arranged in the fork and can be displaced into the braking position via a tappet actuated by a trip cam. A direction lock can be set without a braking action on the running wheel. Two tappets are movable independently of each other, wherein only the direction lock without a braking action can be set via one of the tappets. Another caster includes a running wheel, a fork and an assembly journal, wherein a braking device is provided in the fork and can be displaced into the braking position via a trip cam. The braking device has a first braking part for friction-locking action on the running wheel and a second braking part for the interlocking lock of the running wheel.
