Abstract

A retractable USB stick comprises: an elongate housing having an open end, a USB stick disposed within the elongate housing, and means for causing the USB stick to project out of and retract back into the housing. The means for causing the USB stick to project may be patterned after comparable means in a lipstick dispenser mechanism of U.S. Pat. No. 3,941,489. The means for causing the USB stick to project/retract may comprise an outer holder having an elongate housing with an opening at one end, an intermediate sleeve sized disposed between the USB stick and the holder, and means for imparting reverse motion includes a toothed wheel disposed at a back end of the intermediate sleeve, teeth on an inner surface of the outer holder and teeth on an elongate linear track extending from the back end of the USB stick. Optionally, the USB stick may be releasably locked in the open position, and means may be provided for closing the open end of the housing.

Claims

1. Retractable USB stick comprising:

an elongate housing having an open end;

a USB stick disposed within the elongate housing; and

means for causing the USB stick to project at least partially out of the open end of the housing in an open position;

wherein the means for causing the USB stick to project at least partially out of the open end of the housing comprises;

an outer holder comprising an elongate housing with an opening at one end;

an intermediate sleeve disposed between the USB stick and the holder; and

means for imparting reverse motion such that moving the outer housing relative to the intermediate sleeve causes the USB stick to extend from and retract into the intermediate sleeve.

2. The retractable USB stick of claim 1, wherein the means for causing the USB stick to project at least partially out of the open end of the housing causes the USB stick to project substantially fully out of the housing.

3. The retractable USB stick of claim 1, wherein the means for causing the USB stick to project at least partially out of the open end of the housing causes the USB stick to project sufficiently out of the housing so that a USB connector at an end of the USB stick is adequately exposed for plugging into a personal computer.

4. The retractable USB stick of claim 1, further comprising:

means for releasably locking the USB stick in the open position.

5. The retractable USB stick of claim 1, further comprising:

means for closing the open end of the housing.

6. The retractable USB stick of claim 1, wherein the means for causing the USB stick to project at least partially out of the open end of the housing is patterned after comparable means in a lipstick dispenser mechanism of U.S. Pat. No. 3,941,489.

7. The retractable USB stick of claim 1, wherein the means for imparting reverse motion comprises:

a toothed wheel disposed at a back end of the intermediate sleeve;

teeth on an inner surface of the outer holder; and

teeth on an elongate linear track extending from the back end of the USB stick.

8. The retractable USB stick of claim 1, further comprising:

an antenna.

9. The retractable USB stick of claim 4, further comprising:

the antenna is incorporated into the means for causing the USB stick to project at least partially out of the open end of the housing.

10. Method of using a USB stick, comprising:

providing a housing for the USB stick;

disposing the USB stick within the housing;

providing a fingerpiece extending through a longitudinal slot in the housing;

moving the fingerpiece in a reverse direction causes the USB stick to move in a forward direction through an opening in a front end of the housing, to an open position; and

moving the fingerpiece in the forward direction causes the USB stick to move in the reverse direction through the opening in a front end of the housing.

11. The method of claim 10, further comprising:

providing means for releasably locking the USB stick in the open position.

12. The method of claim 10, further comprising:

providing means for closing the opening in the front end of the housing.

13. Retractable USB stick comprising:

an elongate housing having a front end;

a USB stick disposed within the elongate housing; and

means for causing the USB stick to project at least partially out of an opening at the front end of the housing in an open position;

wherein the means for causing the USB stick to project at least partially out of the opening comprises;

an elongate strap extends from a back end of a main body of the USB stick, towards a back end of the housing, wraps around a fixed boss a disposed near the back end of the housing, then extends back towards the front end housing, passing alongside of the USB stick, to the front end of the housing; and

the means for imparting reverse motion comprises a fingerpiece extending from the strap though a slot in the housing such that moving the fingerpiece relative to the outer housing causes the USB stick to extend from and retract into the housing.

14. The retractable USB stick of claim 13, further comprising:

means for closing the opening at the front end of the elongate housing in a closed position.

15. The retractable USB stick of claim 14, wherein the means for closing the opening comprises:

a flap extends from an opposite end of the strap, across the opening, and is sized and shaped to cover the opening in the closed position.

16. The retractable USB stick of claim 13, wherein the means for closing the opening comprises:

two resilient flaps fixed to opposite sides of the opening and facing each other, which would deflect when the USB stick is extended out of the housing and which return when the USB stick is retracted to within the housing.

17. The retractable USB stick of claim 13, wherein the means for causing the USB stick to project at least partially out of the open end of the housing causes the USB stick to project sufficiently out of the housing so that a USB connector at an end of the USB stick is adequately exposed for plugging into a personal computer.

18. The retractable USB stick of claim 13, further comprising:

means for releasably locking the USB stick in the open position.

19. The retractable USB stick of claim 13, further comprising:

an antenna.

20. The retractable USB stick of claim 19, further comprising:

the antenna is incorporated into the means for causing the USB stick to project at least partially out of the open end of the housing.
