Abstract

A USB device including a tubular housing and a rear cap assembly including a handle structure that is rotatably connected to the tubular housing to facilitate deploying and retracting a plug connector through a front opening of the housing. The plug connector is fixedly connected onto the front end of a sliding rack assembly that is disposed in housing such that the sliding rack assembly is slidable along a longitudinal axis. The sliding rack assembly includes a carrier including a carrier tray for supporting electronic devices and an elongated positioning rod extending from a rear portion of the carrier tray. The positioning rod is operably engaged with an actuator portion such that manual rotation of the rear cap handle structure relative to the housing around the longitudinal axis causes the sliding rack assembly to slide inside the housing between retracted and deployed positions.

Claims

1. A lipstick-type portable computer peripheral apparatus comprising:

a single-piece tubular housing having a front end portion defining a front opening, opposing side walls and opposing upper and lower walls extending from the front end portion and defining an elongated central cavity, and a rear edge disposed at a back portion of the central cavity and defining a rear opening;

sliding rack assembly movably disposed in the tubular housing such that the sliding rack assembly is slidable along a longitudinal axis extending through the elongated central cavity, the sliding rack assembly including;

a carrier including a carrier tray and an elongated positioning rod extending from a rear portion of the carrier tray and a positioning structure disposed on the positioning rod;

at least one electronic device fixedly connected to the carrier; and

a plug connector mounted on the carrier and disposed at a front end of the sliding rack assembly; and

a rear cap assembly connected to the rear edge of the tubular housing, the rear cap assembly including a handle structure that is disposed outside of the tubular housing and an actuator portion disposed inside one of the tubular housing and the handle structure, the actuator portion being operably engaged with the positioning structure such that manual rotation of the handle structure relative to the tubular housing around the longitudinal axis causes the sliding rack assembly to slide inside the tubular housing between a retracted position in which said plug connector is disposed inside of the tubular housing, and a deployed position in which said plug connector is exposed outside said front opening for operable coupling to a host system.

2. The lipstick-type portable computer peripheral apparatus according to claim 1,

wherein the positioning structure comprises one or more positioning knobs disposed on the positioning rod,

wherein the actuator portion of the rear cap assembly includes one of a curved cam surface and a spiral groove, and

wherein the positioning knob is operably engaged with said one of said curved cam surface and said spiral groove such that the positioning knob remains in contact with said one of said curved cam surface and said spiral groove while manual rotation of the handle structure relative to the tubular housing causes the sliding rack assembly to slide between the retracted position and the deployed position.

3. The lipstick-type portable computer peripheral apparatus according to claim 1, wherein the handle structure of the rear cap assembly further comprises opposing upper and lower walls are shaped such that the upper and lower walls of the handle structure are respectively aligned with the opposing upper and lower walls of the tubular housing when the plug connector is in both the fully deployed and fully retracted positions.

4. The lipstick-type portable computer peripheral apparatus according to claim 1, wherein the opposing upper and lower walls of the handle structure and the opposing upper and lower walls of the tubular housing comprise planar surfaces arranged such that the upper and lower walls of the rear cap assembly form coplanar surfaces with the opposing upper and lower walls of the tubular housing when the plug connector is in both the fully deployed and fully retracted positions.

5. The lipstick-type portable computer peripheral apparatus according to claim 1, wherein the opposing upper and lower walls of the handle structure and the opposing upper and lower walls of the tubular housing comprise curved surfaces shaped and arranged such that the upper and lower walls of the rear cap assembly form continuous curved surfaces with the opposing upper and lower walls of the tubular housing when the plug connector is in both the fully deployed and fully retracted positions.

6. The lipstick-type portable computer peripheral apparatus according to claim 1,

wherein the rear edge of the tubular housing defines a seat,

wherein the tubular housing includes a plurality of first locking structures disposed inside the elongated inner chamber,

wherein the rear cap assembly further includes a coupling structure having a flat wall and a plurality of second locking structures that protrude from the flat wall, the flat wall having a peripheral edge that is sized to fit inside the seat, and each of the plurality of second locking structures being fixedly connected to an associated one of the plurality of first locking structures, and

wherein the handle structure is rotatably connected to the coupling structure.

7. The lipstick-type portable computer peripheral apparatus according to claim 6,

wherein the handle structure of the rear cap assembly includes a mounting structure,

wherein the coupling structure defines a central opening and multiple slits extending radially outward from the central opening, and

wherein the handle structure is rotatably mounted onto the coupling structure such that the mounting structure extends through the central opening.

8. The lipstick-type portable computer peripheral apparatus according to claim 1, further comprising a resilient member disposed in the tubular housing such that the resilient member biases the sliding rack assembly along the longitudinal axis.

9. The lipstick-type portable computer peripheral apparatus according to claim 1, wherein said actuator portion is engaged with said positioning structure such that the handle structure of the rear cap assembly is freely rotatable around the longitudinal axis relative to the housing.

10. The lipstick-type portable computer peripheral apparatus according to claim 9,

wherein the positioning structure comprises one or more positioning knobs disposed on the positioning rod,

wherein the actuator portion includes a substantially oval cam surface, and

wherein the apparatus further comprises a resilient member operably disposed in the housing to bias the sliding rack assembly toward the rear cap assembly such that the one or more positioning knobs are slidably pressed against the cam surface, whereby the force exerted on the positioning knobs by the cam surface while the handle structure is rotated relative to the tubular housing causes displacement of the sliding rack assembly inside the tubular housing along the longitudinal axis.

11. The lipstick-type portable computer peripheral apparatus according to claim 10, wherein the substantially oval cam surface includes a first locking groove and a second locking groove, the first locking groove being disposed on the substantially oval cam surface at a position closer to the resilient member than that of the second locking groove, whereby when the handle structure is rotated relative to the tubular housing such that the positing knob enters the first locking groove, the sliding rack assembly is stably maintained in the deployed position, and when the handle structure is rotated relative to the tubular housing such that the positing knob enters the second locking groove, the sliding rack assembly is stably maintained in the retracted position.

12. The lipstick-type portable computer peripheral apparatus according to claim 11, wherein the actuator portion comprises a hollow cylindrical wedge-shaped structure integrally molded to said handle structure and extending through said rear opening into said tubular housing, said hollow cylindrical wedge-shaped mounting structure having a peripheral edge defining said substantially oval cam surface.
