System for selectively extending and retracting a license plate holder

1. A system for selectively extending and retracting a license plate holder, the system comprising:

a housing comprising a slide rail attachable to a vehicle;

a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction;

a first slider slidably disposed within the slide rail and operably coupled to the driver so as to move in a first and a second generally opposite direction along a length of the driver as the driver is rotated;

a second slider disposed within the slide rail in spaced relation to the first slider and operably coupled to the driver to move in first and second generally opposite directions along a length of the driver as the driver is rotated;

a spring disposed between the first and second sliders for biasing the first and second sliders in spaced relation to one another; and

a license plate mount pivotally attached to the first slider;

wherein when the driver is rotated in the first rotational direction, the first slider moves in the first direction a predetermined distance, and the license plate mount pivots to an extended position; and

wherein when the driver is rotated in the generally opposite second rotational direction, the first slider moves in the second direction and the license plate mount pivots to a retracted position.

2. The system of claim 1 , including a stop for limiting the travel of the first slider in the first direction.

3. The system of claim 1 , including a sensor for detecting a position of the first slider and/or the second slider.

4. The system of claim 1 , including an inner slide rail slidably disposed within the housing.

5. The system of claim 4 , wherein the first slider and the second slider are slidably disposed within the inner slide rail.

6. The system of claim 4 , including a stop for limiting travel of the inner slide rail within the housing.

7. A system for selectively extending and retracting a license plate holder, the system comprising:

a housing comprising a slide rail attachable to a vehicle;

a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction;

a first slider slidably disposed within the slide rail and operably coupled to the threaded driver so as to move in a first and a second generally opposite direction along a length thereof as the driver is rotated;

a second slider slidably disposed within the slide rail and operably coupled to the threaded driver so as to move in first and second generally opposite directions along a length thereof as the threaded driver is rotated;

a license plate mount pivotally attached to the second slider; and

a link extending between the first slider and the license plate mount;

wherein when the threaded driver is rotated in the first rotational direction, the first slider moves towards the second slider and a distance between the first slider and the license plate mount becomes less than a length of the link, and the license plate mount pivots to an extended position; and

wherein when the threaded driver is rotated in the generally opposite second rotational direction, and the first slider moves away from the license plate mount, the link causes the license plate mount to pivot to a retracted position.

8. The system of claim 7 , including a spring disposed between the first and second sliders for biasing the first and second sliders in spaced relation to one another.

9. The system of claim 7 , including a stop for limiting the travel of the first slider in the first direction.

10. The system of claim 7 , including a sensor for detecting a position of the first slider and/or the second slider.

11. The system of claim 7 , including an inner slide rail slidably disposed within the housing.

12. The system of claim 11 , wherein the first slider and the second slider are slidably disposed within the inner slide rail.

13. The system of claim 11 , including a stop for limiting travel of the inner slide rail within the housing.

14. A system for selectively extending and retracting a license plate holder, the system comprising:

a housing comprising a slide rail attachable to a vehicle;

a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction;

a first slider slidably disposed within the slide rail and operably coupled to the threaded driver so as to move in a first and a second generally opposite direction along a length thereof as the driver is rotated;

a second slider slidably disposed within the slide rail and operably coupled to the threaded driver so as to move in first and second generally opposite directions along a length thereof as the threaded driver is rotated;

a spring disposed between the first and second sliders for biasing the first and second sliders in spaced relation to one another;

a stop for limiting the travel of the first slider in the first direction;

a sensor for detecting a position of the first slider and/or the second slider;

a license plate mount pivotally attached to the second slider; and

a link extending between the first slider and the license plate mount;

wherein when the threaded driver is rotated in the first rotational direction, the first slider moves towards the second slider and a distance between the first slider and the license plate mount becomes less than a length of the link, and the license plate mount pivots to an extended position; and

wherein as the threaded driver is rotated in the general opposite second rotational direction and the first slider moves away from the license plate mount, the link causes the license plate mount to pivot to a retracted position.

15. The system of claim 14 , including an inner slide rail slidably disposed within the housing.

16. The system of claim 15 , wherein the first slider and the second slider are slidably disposed within the inner slide rail.

17. The system of claim 15 , including a stop for limiting travel of the inner slide rail within the housing.

18. A system for selectively extending and retracting a license plate holder, the system comprising:

a housing comprising a slide rail attachable to a vehicle;

an inner slide rail slidably disposed within the housing;

a threaded driver disposed within the slide rail and operably coupled to a motor for selectively rotating the threaded driver in a first rotational direction or a generally opposite second rotational direction;

a first slider slidably disposed within the slide rail and operably coupled to the driver so as to move in a first and a second generally opposite direction along a length of the driver as the driver is rotated;

a second slider disposed within the slide rail in spaced relation to the first slider and operably coupled to the driver to move in first and second generally opposite directions along a length of the driver as the driver is rotated; and

a license plate mount pivotally attached to the first slider;

wherein when the driver is rotated in the first rotational direction, the first slider moves in the first direction a predetermined distance, and the license plate mount pivots to an extended position; and

wherein when the driver is rotated in the generally opposite second rotational direction, the first slider moves in the second direction and the license plate mount pivots to a retracted position.

19. The system of claim 18 , wherein the first slider and the second slider are slidably disposed within the inner slide rail.

20. The system of claim 18 , including a stop for limiting travel of the inner slide rail within the housing.
