Claims4
A furniture caster stop for immobilizing a caster on which an article of furniture is mounted, comprising a flat body having two spaced parallel upright walls forming an upwardly opening slot therebetween for receiving the wheel of a furniture-mounting caster with its axle extending transversely of said slot, and said slot between said walls having a width slightly greater than the axial thickness of such wheel, said slot having an aperture in its bottom between said walls for enabling the wheel of a caster received in said slot to engage and rest on the floor through said aperture, and said body having opposed ramps sloping oppositely upward from said aperture for engagement of either ramp by a caster wheel rolling from the floor out of said aperture.
The process of stabilizing an article of furniture mounted on casters resting on the floor to deter appreciable shifting of such article over the floor, which comprises substantially immobilizing at least two caster supporting such article of furniture by confining the wheel of each of such casters between parallel walls spaced apart slightly farther than the width of the caster wheel and opposed spaced ramps onto one of which ramps the caster wheel can roll from the floor between the opposed spaced ramps by application of a displacing force to such article of furniture in any direction and thereby applying a downward force on such a ramp to hold such ramp in fixed position, and by such rolling of a caster wheel up a ramp producing a component of force on the caster in a direction opposite the displacing force and tending to roll its wheel down the ramp.
