  • Patent number: 8678335
    Abstract: The present invention is directed to a caster stop. Advantageously, the caster stop has a generally circular shape, and includes a concave portion for receiving a caster wheel, and a ramp that spans between a circumferential rim and a generally circular foot. The ramp facilitates wheel movement in-and-out of the concave portion of the caster stop. Also provided is an inventive method that does not require lifting caster-mounted equipment either to position caster wheels in caster stops or to displace caster-mounted equipment from caster stops. Instead, exerting a pushing force on caster-mounted equipment is sufficient for in-and-out movement. This invention is especially useful for caster-mounted cooking equipment in commercial kitchens.
