Abstract

A gate assembly comprising a gate mount and a gate mounted for movement on the gate mount between an opened position and a closed position. The gate assembly further comprises an illumination system mounted on the gate mount for turning on a light mounted on the gate mount when someone approaches the gate when it is dark in the vicinity of the gate.

Claims

1. A gate assembly comprising

a gate mount,

a gate mounted on a portion of the gate mount for movement between an opened position and a closed position, and

illumination means mounted on the gate mount for turning on a light mounted on the gate mount when someone approaches the gate when it is dark.

2. The gate assembly of claim 1, wherein the illumination means includes a photo sensor configured to detect a darkness condition, a motion sensor configured to detect motion in a motion-detection zone, and a controller configured to turn on the light when both a darkness condition is sensed by the photo sensor and the motion sensor detects motion in the motion-detection zone.

3. The gate assembly of claim 2, wherein the darkness condition is a predetermined amount of light in a darkened navigation area around at least one of the gate mount and the gate.

4. The gate assembly of claim 3, wherein the light is configured to illuminate the darkened navigation area.

5. The gate assembly of claim 2, wherein the motion-detection zone includes an area around at least one of the gate mount and the gate.

6. The gate assembly of claim 1, wherein the gate mount includes a pivot support frame configured to be coupled to a first side of the gate and a latch receiver frame configured to mate with a latch on a second side of the gate.

7. The gate assembly of claim 6, wherein the illumination means is mounted on the latch receiver frame.

8. The gate assembly of claim 7, wherein the illumination means includes a photo sensor configured to detect a darkness condition, a motion sensor configured to detect motion in a motion-detection zone, and a controller configured to turn on the light when both a darkness condition is sensed by the photo sensor and the motion sensors detects motion in the motion-detection zone.

9. The gate assembly of claim 2, wherein the darkness condition is a predetermined amount of light in a darkened navigation area around the latch receiver frame.

10. The gate assembly of claim 9, wherein when the gate is not mounted on the gate mount, the illumination means operates to illuminate the darkened navigation area around the latch receiver frame when the motion sensor detects motion in the motion-detection zone.

15. The gate assembly of claim 11, wherein the darkness condition is a predetermined amount of light in a darkened navigation area around at least one of the gate mount and the gate.

16. The gate assembly of claim 15, wherein the photo sensor, motion sensor, and light source are connected to the controller, and when the photo sensor detects the darkness condition, the photo sensor sends a darkness-sensing signal to the controller whereby the controller turns on the motion sensor.

17. The gate assembly of claim 16, wherein when the motion sensor detects motion in the motion-detection zone, the motion sensor sends a motion-sensing signal to the controller to cause the controller to turn on the light source which shines a light on the darkened navigation area.

11. A gate assembly comprising

a gate mount,

a gate mounted on a portion of the gate mount for movement between an opened position and a closed position, and

a lighting device mounted on the gate mount, the lighting device including a photo sensor configured to detect a darkness condition, a motion sensor configured to detect motion in a motion-detection zone, a light source, and a controller configured to turn on the light source when both a darkness condition is sensed by the photo sensor and the motion sensor detects motion in the motion-detection zone.

12. The gate assembly of claim 11, wherein the gate mount includes a pivot support frame configured to be coupled to a first side of the gate and a latch receiver frame configured to mate with a latch on a second side of the gate.

13. The gate assembly of claim 12, wherein the lighting device is mounted on the latch receiver frame.

14. The gate assembly of claim 13, wherein when the gate is not mounted on the gate mount, the lighting device operates to turn on the light source when both a darkness condition is sensed by the photo sensor and the motion sensor detects motion in the motion-detection zone.

18. The gate assembly of claim 11, wherein the light source includes at least one LED and a power source and when the controller detects a predetermined power source value indicating a low-power condition, the at least one LED is turned on and flashes at a predetermined rate for a first predetermined period of time.

19. The gate assembly of claim 18, wherein when the controller detects the predetermined power source value indicating a low power condition, and the motion detector has detected motion in the motion-detection zone, the at least one LED is turned on and flashes at the specified rate for the first predetermined period of time after which the at least one LED remains on for a second predetermined period of time after the last motion is detected by the motion sensor.

20. The gate assembly of claim 12, wherein the motion-detection zone includes an area around the latch receiver frame established by the motion sensor and the motion-detection zone is established whether or not the gate is mounted on the gate mount.

21. A gate assembly comprising

a gate mount including a hinge assembly portion and a latch-receiver portion,

a gate mounted on the hinge assembly portion for movement on the gate mount between an opened position and a closed position, and

a light source mounted on the latch-receiver portion of the gate mount, the latch-receiver portion including a controller, a photo sensor, and a motion sensor, the light source being connected to and turned on by the controller when a darkness condition is detected by the photo sensor and motion is detected by the motion sensor in a motion-detection zone to illuminate the gate and the motion-detection zone.

22. The gate assembly of claim 21, wherein the light source remains turned on for a predetermined period of time after the last motion is detected by the motion sensor.

23. The gate assembly of claim 21, wherein the light source is off so long as the motion sensor fails to detect motion in the motion-detection zone.

24. The gate assembly of claim 21, wherein the light source includes at least one LED and a light diffuser and the light diffuser includes at least one light pipe to at least partially enclose the at least one LED.

25. The gate assembly of claim 21, wherein the latch receiver portion is configured to mate with a latch on the gate to retain the gate in a closed position.
