Lockable caster, more particularly swivel caster

Abstract

Abstract A lockable caster, more particularly a swivel caster, having a locking dee for locking the running wheel to prevent it from running and/or to prevent the caster-fork from swivelling. In the cavity of the caster-fork is disposed an expanding toggle which takes the form of a foot-operated control lever, which is pivotally mounted in a socket, and is guided by a guide lug in a guide slot. On the trailing side of the caster, the expanding toggle is pivotally mounted below the fork back in a socket of a resilient or spring-loaded locking rocker. The fork back and locking rocker enclose the expanding toggle between themselves with prestressing. The guide slot may be disposed in the rear portion of the caster-fork. The guide lug takes the form of a resetting cam which in the locking position extends out of the guide slot to form a foot-operated cam to tilt the expanding toggle back into its release position. In an embodiment the back portion of the caster-fork is inclined downwards on the trailing side of the caster and its guide slot forms an inclined slideway over which the resetting cam can shoot back into the release position of the expanding toggle.
