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. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A caster (1) comprising a running wheel (6), a fork (2) and an assembly journal (3), wherein the fork (2) is pivotable relative to the assembly journal (3) and a braking device is arranged in the fork (2) which can be displaced into the braking position via a tappet (13) actuated by a trip cam (8), wherein furthermore a direction lock can be set without a braking action on the running wheel (6), and two tappets (12, 13) are provided which are movable independently of each other, wherein only the direction lock without braking action can be set via one of the tappets (12), wherein in the normal operating position of caster (1), the tappets (12, 13) are arranged next to one another transverse to a vertical direction and extend next to one another in the vertical direction, the trip cam (8) has two cam surfaces (21, 22) which are each assigned to one of the tappets (12, 13) and the cam surfaces (21, 22) are designed differently from one another. ### Claim 17 A caster (1) comprising a running wheel (6), a fork (2) and an assembly journal (3), wherein a braking device is provided in the fork (2) which can be displaced into the braking position preferably via a trip cam (8), wherein the braking device has a first braking part (41) for friction-locking action on the running wheel (6), wherein the braking device has a second braking part (46) for the interlocking lock of the running wheel (6) for the combined interlocking and frictional lock position of the running wheel. ### Claim 18 (depends on 17) The caster according to claim 17, wherein furthermore a direction lock can be set without a braking action on the running wheel (6), and two tappets (12, 13) are provided which are movable independently of each other, wherein only the direction lock without braking action can be set via one of the tappets (12). ### Claim 19 (depends on 18) The caster according to claim 18, wherein the trip cam (8) has two cam surfaces (21, 22) which are each assigned to one of the tappets (12, 13), and the cam surfaces (21, 22) are designed differently from one another. ### Claim 20 (depends on 16) The caster according to claim 16, wherein the trip cam (8) is designed in two parts, with one first and one second partial cam (23, 24). ### Claim 21 (depends on 16) The caster according to claim 16, wherein the trip cam (8) acts on one or both tappets (12, 13) by means of a roller bearing (15). ### Claim 22 (depends on 21) The caster according to claim 21, wherein one or both roller bearings (15) are mounted on one or each on one of the tappets (12, 13). ### Claim 23 (depends on 20) The caster according to claim 20, wherein the first partial cam (23) penetrates the second partial cam (24) in a direction transverse to the vertical direction. ### Claim 24 (depends on 20) The caster according to claim 20, wherein the trip cam (8) is penetrated by a switching lever (11), which, in the case of the partial cams (23, 24), only acts directly on one of the partial cams (23). ### Claim 25 (depends on 20) The caster according to claim 20, wherein the first partial cam (23) is rotatable relative to the second partial cam (24) about an axis of rotation (b), about which the trip cam (8) is to be rotated during actuation. ### Claim 26 (depends on 18) The caster according to claim 18, wherein one of the tappets (13) interacts with a braking part, wherein the braking part comprises a first friction-locking braking part (41) and a second interlocking lock braking part (46). ### Claim 27 (depends on 17) The caster according to claim 17, wherein the first friction-locking and the second interlocking lock braking parts (41, 46) are designed fixedly connected to one another. ### Claim 28 (depends on 16) The caster according to claim 16, wherein the running wheel (6) has a sprocket (49), for interaction with the second interlocking lock braking part (46). ### Claim 29 (depends on 26) The caster according to claim 26, wherein interlocking devices (48) of the second braking part (46) are fixed on a part rigidly connected to the first braking part (41) yet also elastically movable with respect thereto. ### Claim 30 (depends on 26) The caster according to claim 26, wherein the second interlocking lock braking part (46) is designed on an arm (47) projecting from the first braking part (41) in the circumferential direction of the running wheel (6).
