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.
