PCT No. PCT/EP95/00940 Sec. 371 Date Oct. 29, 1996 Sec. 102(e) Date Oct. 29, 1996 PCT Filed Mar. 14, 1995 PCT Pub. No. WO95/28293 PCT Pub. Date Oct. 26, 1995The invention relates to a roller, especially a deflection roller (R), with a fork (2) bearing the tyred running wheel (1) and a braking device (25), at least for the rotary movement of the wheel (1), which has a push-rod (10) which can be moved towards the wheel (1) via an actuating device (1), a braking component (26) pressing into the tire (29) and a power storage spring (F) between the actuating device (11) and the braking device (11), and, in order to provide an easily used, tire saving braking device, proposes that the characteristic/prestress on the power storage spring (F) be designed in relation to the pressure resistance of the tire (29) in such a way that, in the braking position of the actuating device (11), in relation to the braking component (26), a determined depth of penetration into the tire (29) stopping the rotation of the wheel (1) is maintained and not exceeded. |
