Automated sliding panel mechanism with manual release mechanism

1. A mechanism coupling a sliding panel to a frame, wherein the sliding panel moves within the frame between an open position and a closed position, the mechanism comprising:

a motor configured to move the sliding panel between the closed position and the open position,

a power source, providing power to the motor,

a rack comprising a base with rack teeth extending from a plane thereof;

a gear rotated by the motor about a gear axis of rotation, the gear comprising gear teeth shaped to mesh with the rack teeth;

a manual release mechanism configured to move the gear along the gear axis of rotation, from an engaged position, wherein the gear teeth mesh with the rack teeth, to a released position, wherein the gear teeth are disengaged from the rack teeth; and

a holding mechanism adapted to hold the gear in the engaged position and in the released position as selected by a user;

wherein the motor is coupled to one of the sliding panel and the frame and the rack is attached to the other of the sliding panel and the frame, wherein operation of the motor causes the sliding panel to move relative to the frame.

2. The invention of claim 1 , wherein the holding mechanism comprises a first and a second magnet mounted on the holding mechanism and a third magnet mounted on the manual release mechanism, wherein, when the third magnet is brought sufficiently close to the first magnet to magnetically attract the first magnet, the holding mechanism holds the gear in the engaged position and wherein, when the third magnet is brought sufficiently close to the second magnet to magnetically attract the second magnet, the holding mechanism holds the gear in the released position.

3. The invention of claim 1 , wherein the holding mechanism comprises a first and a second magnet mounted on the manual release mechanism and a third magnet mounted on a stationary part of the holding mechanism, wherein, when the first magnet is brought sufficiently close to the third magnet to magnetically attract the third magnet, the holding mechanism holds the gear in the engaged position and wherein, when the second magnet is brought sufficiently close to the third magnet to magnetically attract the third magnet, the holding mechanism holds the gear in the released position.

4. The invention of claim 1 , further comprising gearing between the motor and the gear, and wherein the gearing is configured to prevent rotation of the gear when not driven by the motor.

5. The invention of claim 1 , further comprising a brake to prevent the gear from rotating and thereby lock the sliding panel when the manual release mechanism is in the engaged position except by rotation of the gear by the motor.

6. The invention of claim 1 , wherein the manual release mechanism comprises a surface which is moved by a user to move the automated sliding panel mechanism between the engaged position and the released position.

7. The invention of claim 6 , wherein the manual release mechanism surface comprises indicia which indicates in which direction to move the manual release mechanism to achieve the engaged position and which direction to move the manual release mechanism to achieve the released position.

8. The invention of claim 6 , wherein the manual release mechanism surface and manual release mechanism carriage are one piece.

9. The invention of claim 1 , wherein the manual release mechanism surface is a lever which is moved by a user to move the manual release mechanism between an engaged position and a released position.

10. The invention of claim 1 , wherein the manual release mechanism comprises a carriage.

11. The invention of claim 1 , wherein the gear is a helical gear.

12. The invention of claim 1 , wherein the gear is a spur gear.

13. The invention of claim 1 , wherein the sliding panel is a window or a door.

14. The invention of claim 1 , wherein the power source is a solar panel.

15. A mechanism coupling a sliding panel to a stationary component, the mechanism comprising:

a motor configured to move the sliding panel between a closed position and an open position relative to the stationary component;

a power source, providing power to the motor;

a rack comprising a base with rack teeth extending from a plane thereof;

a gear rotated by the motor around an axis of rotation, the gear comprising gear teeth shaped to mesh with the rack teeth;

a manual release mechanism adapted to move the gear along the axis of rotation, from an engaged position, wherein the gear teeth mesh with the rack teeth to a released position, wherein the gear teeth are disengaged from the rack teeth; and

a holding mechanism adapted to hold the gear in the engaged position and in the released position, wherein the holding mechanism comprises a first magnet, second magnet, and third magnet mounted on the holding mechanism, wherein, when the third magnet is brought sufficiently close to the first magnet to magnetically attract the first magnet, the holding mechanism holds the gear in the engaged position and wherein, when the third magnet is brought sufficiently close to the second magnet to magnetically attract the second magnet, the holding mechanism holds the gear in the released position.

16. The invention of claim 15 , further comprising gearing between the motor and the gear, and wherein the gearing is configured to prevent rotation of the gear when not driven by the motor.

17. The invention of claim 15 , further comprising a brake to prevent the gear from rotating and thereby lock the sliding panel when the manual release mechanism is in the engaged position except by rotation of the gear by the motor.

18. The invention of claim 15 , wherein the magnets are permanent magnets.

19. The invention of claim 15 , wherein the manual release mechanism further comprises a carriage.

20. The invention of claim 15 , wherein the manual release mechanism comprises a surface which is moved to move the automated sliding panel mechanism between an engaged position and a released position.
