ABSTRACT:
A caster device with blocking of rotation of the caster wheel and of swiveling movement of a caster-wheel fork by displacement of a spindle which is disposed concentric to the swivel axis of the caster-wheel fork, the spindle being displaceable along the axis and passing through a head plate of the fork, there being a mounting plate disposed above the head plate; and wherein the lower end of the spindle, upon initial displacement to a first position blocks a swiveling motion of the caster-wheel fork by tooth engagement therewith and, after a second displacement to a second position, blocks rotation of the caster wheel by means of a breaking action on an impact surface. A device activated by the spindle blocks the swiveling motion of the fork and a device activated by the spindle blocks rotation of the caster wheel. Each of the blocking a device is bringable into engagement separately from each other to a depth of engagement which is individually adjustable.
