Abstract

A luggage apparatus comprising a rigid case body having retractable wheels concealable within recessed compartments in the base is disclosed. The apparatus includes a control (i.e., actuation) interface disposed on the exterior of the case body, operable in a first position to retract the wheels into the compartments and in a second position to deploy or extend the wheels for rolling. Each wheel is coupled to either a spring-loaded mechanism or an electric motor system to enable vertical movement between the retracted and extended positions. The spring mechanism comprises a helical compression spring aligned around a vertical wheel shaft, while the motorized embodiment employs a mini electric motor coupled to a vertical actuator. The control (i.e., actuation) button is configured for dual-mode operation and is compatible with both mechanical and electrical systems.
