Abstract

An electrical pop out device has a shroud and an outlet housing. The outlet housing is sized to be placed inside the shroud. A guidance mechanism connects the outlet housing with the shroud. The guidance mechanism includes multiple rack gears and multiple pinion gears. The outlet housing is moveable with respect to the shroud along a direction defined by the rack gear. A spring connector electrically couples the shroud to the outlet housing.

Claims

1. An electrical pop out device comprising:

a shroud;

an outlet housing being sized to be placed inside the shroud;

a guidance mechanism connecting the outlet housing with the shroud, the guidance mechanism being configured to allow movement of the outlet housing with respect to the shroud and to prevent misalignment of the outlet housing with respect to the shroud during movement of the outlet housing; and

a spring connector disposed between the shroud and the outlet housing, the spring connector being configured to mechanically expel the outlet housing from within the shroud;

wherein the guidance mechanism includes multiple rack and pinion gear sets, each rack and pinion gear set having at least one rack gear and at least one pinion gear, the outlet housing being moveable with respect to the shroud along a direction defined by the rack gears; and

wherein at least two rack and pinion gear sets are diametrically opposed about the outlet housing.

2. The electric pop out device according to claim 1, wherein the pinion gears of each rack and pinion gear set are rotatably attached to the outlet housing.

3. The electric pop out device according to claim 2, wherein the guidance mechanism additionally comprises a retention frame attached to the outlet housing;

and

wherein the pinion gears are rotatably attached to the outlet housing by the retention frame.

4. The electrical pop out device according to claim 1, additionally comprising a sub-plate that is connectable to the shroud and is adapted to retain the guidance mechanism within the shroud.

5. The electrical pop out device according to claim 1, wherein the outlet housing includes at least a pair of outlets placed about the outlet housing to provide access to each of the pair of outlets from different directions.

6. The electrical pop out device according to claim 1, wherein the outlet housing includes a single outlet placed on a front face of the outlet housing.

7. The electrical pop out device according to claim 1, wherein the guidance mechanism restricts movement of the outlet housing with respect to the shroud to a single direction.

8. The electrical pop out device according to claim 1, wherein the spring connector has a first end connected with the shroud and a second end connected with the outlet housing.

9. The electrical pop out device according to claim 1, further comprising an electrical connector coupled to the shroud for attaching the electrical pop out device to an electrical circuit.

10. The electrical pop out device according to claim 1, further comprising a push-push latch operatively connected with the shroud and the outlet housing.

11. The electrical pop out device according to claim 1,

wherein the guidance mechanism is configured to counteract a load applied to a side of the outlet housing.

12. The electrical pop out device according to claim 1, further comprising a USB port formed in the outlet housing.

13. The electrical pop out device according to claim 1, wherein the shroud is adapted to fit into a single gang box.

14. The electric pop out device according to claim 1, wherein the rack gears of each rack and pinion gear set are disposed on the shroud and extend from an opening in the shroud straight back into an interior of the shroud.

15. An electrical pop out device comprising:

a shroud;

an outlet housing being sized to be placed inside the shroud;

a guidance mechanism connecting the outlet housing with the shroud, the guidance mechanism being configured to allow movement of the outlet housing with respect to the shroud and to prevent misalignment of the outlet housing with respect to the shroud during movement of the outlet housing; and

a spring connector disposed between the shroud and the outlet housing, the spring connector being configured to mechanically expel the outlet housing from within the shroud;

wherein the guidance mechanism includes multiple rack and pinion gear sets, each rack and pinion gear set having at least one rack gear and at least one pinion gear, the outlet housing being moveable with respect to the shroud along a direction defined by the rack gears; and

wherein at least two rack and pinion gear sets are orthogonally arranged about the outlet housing.

16. The electric pop out device according to claim 15, wherein the pinion gears of each rack and pinion gear set are rotatably attached to the outlet housing.

17. The electric pop out device according to claim 15, wherein the guidance mechanism additionally comprises a retention frame attached to the outlet housing;

and

wherein the pinion gears are rotatably attached to the outlet housing by the retention frame.

18. The electric pop out device according to claim 15, wherein the rack gears of each rack and pinion gear set are disposed on the shroud and extend from an opening in the shroud straight back into an interior of the shroud.

19. An electrical pop out device comprising:

a shroud;

an outlet housing being sized to be placed inside the shroud;

a guidance mechanism connecting the outlet housing with the shroud, the guidance mechanism being configured to allow movement of the outlet housing with respect to the shroud and to prevent misalignment of the outlet housing with respect to the shroud during movement of the outlet housing; and

a spring connector disposed between the shroud and the outlet housing, the spring connector being configured to mechanically expel the outlet housing from within the shroud;

wherein the guidance mechanism includes multiple rack and pinion gear sets, each rack and pinion gear set having at least one rack gear and at least one pinion gear, the outlet housing being moveable with respect to the shroud along a direction defined by the rack gears;

wherein the pinion gears of each rack and pinion gear set are rotatably attached to the outlet housing;

wherein the guidance mechanism additionally comprises a retention frame attached to the outlet housing; and

wherein the pinion gears are rotatably attached to the outlet housing by the retention frame.

20. An electrical pop out device comprising:

a shroud;

an outlet housing being sized to be placed inside the shroud;

a guidance mechanism connecting the outlet housing with the shroud, the guidance mechanism being configured to allow movement of the outlet housing with respect to the shroud and to prevent misalignment of the outlet housing with respect to the shroud during movement of the outlet housing; and

a spring connector disposed between the shroud and the outlet housing, the spring connector being configured to mechanically expel the outlet housing from within the shroud;

wherein the guidance mechanism includes multiple rack and pinion gear sets, each rack and pinion gear set having at least one rack gear and at least one pinion gear, the outlet housing being moveable with respect to the shroud along a direction defined by the rack gears; and

wherein the rack gears of each rack and pinion gear set are disposed on the shroud and extend from an opening in the shroud straight back into an interior of the shroud.

21. The electric pop out device according to claim 20, wherein at least three independent rack gears are arranged on at least three mutually orthogonal planes to resist twisting of the outlet housing by a combination of resultant reaction vectors aligned with the gear sets.
