Abstract: Particular embodiments disclosed herein provide a retractable guard assembly (104) coupled to a caster of a mobile equipment, comprising a housing (208) and one or more guards (210, 212) at least partially disposed in the housing. The one or more guards are independently movably coupled to the housing. The retractable guard assembly further comprises corresponding one or more biasing elements (330, 332) coupled to the one or more guards and to the housing for biasing the one or more guards towards a fully deployed state. When the one or more guards are in the fully deployed state, contact between a fixed object and a portion of the one or more guards disposed outside the housing causes the one or more guards to transition into a retracted state, and when the contact is removed, the corresponding one or more biasing elements cause the one or more guards to transition into the fully deployed state.

Abstract: The invention provides a retractable guard assembly (104) to be coupled to a caster of a mobile equipment (100), comprising one or more first guards (210a, 210b) comprising corresponding one or more guard toeholds (214a, 214b) and one or more second guards (212a, 212b). When the one or more first guards and the one or more second guards are in a fully retracted state, fully compressing any one of the one or more guard toeholds causes the one or more first guards and the one or more second guards to transition into a fully deployed state. When the one or more first guards and the one or more second guards are in a fully deployed state, fully lifting any one of the one or more guard toeholds causes the one or more first guards and one or more second guards to transition into the fully retracted state.
