A retractable wheel system for luggage. The retractable wheel system includes a luggage body with a base portion, a top portion and a plurality of sides, which define a packing compartment. At least two wheels are pivotably mounted to the base portion of the luggage body. An actuator is coupled to the housing, the actuator retracts or extends a cable wire. The cable wire extends from the actuator to the retractable wheels. The cable wire is guided to a rotary wheel by a pair of cable track wheels. The cable track wheels guide the cable wire along the rotary wheel from the actuator to the wheels. A recoil spring is connected to the actuator, the recoil spring contracts the cable wire and retracts the wheels. Further, a plurality of pockets are disposed at the base portion to house the wheels when the wheels are retracted. |

1. A retractable wheel system for luggage, comprising;
a luggage body, the luggage body comprising a base portion, a top portion a plurality of sides, and a packing compartment; at least two wheels spaced apart at the base portion of the luggage body, wherein the wheels are pivotably mounted to the base portion of the luggage body; an actuator coupled to the luggage body, wherein actuation causes the wheels to transition between an extended and a retracted position; a cable wire extending from the actuator to the wheels at the base portion of the luggage body, wherein the cable wire is manipulated by a movement of the actuator; a rotary wheel operatively connected to the wheels via the cable wire, wherein a pair of cable track wheels guide the cable wire along the rotary wheel from the actuator to the wheels; a recoil spring operatively connected to the actuator and the wheels by the cable wire, wherein the recoil spring contracts the cable wire and retracts the wheels when the actuator is disengaged; and a plurality of pockets at the base portion of the luggage body, the pockets housing the wheels when the recoil spring retracts the wheels. |
