Brake and steering lock for castor

Castor (1) comprising a running wheel, a fork holding the wheel, and a securing device (V) located adjacent to the wheel for blocking a running and/or a steering action of the running wheel (2), said fork (3) being pivotable about a vertical axis (y—y) of the castor, the castor further comprising a push rod (11) for actuating the securing device, and the securing device including steering-blocking mating protrusions (25) and braking-blocking means (26) spaced apart from each other along the vertical axis and being aligned with the fork, wherein the securing device further comprises a braking-blocking and/or steering-blocking formation (22) extending from the push rod in a plane transverse to the vertical axis, the push rod (11) also interacting with the steering-blocking mating protrusions (25) of the securing device, wherein a combination part (K) is constituted by both the steering-blocking mating protrusions (25) and the braking-blocking means (26) of the securing device that are located in spaced-apart planes (E′—E′, E″—E″), the braking-blocking and/or steering-blocking formation (22) of the push rod (11) being located in a neutral position between the planes (E′—E′, E″—E″) during a running and a steering of the castor wheel, wherein the combination part further comprises a braking section extending from the braking-blocking means toward the wheel and being curved to mate with a curvature of the wheel upon being pressed toward the wheel by the push rod, the steering blocking mating protrusions and the braking blocking means being formed as an integral assembly with the braking section.
