Abstract

An electronic keeper includes a housing defining a battery chamber and an actuator chamber. An actuator is at least partially disposed within the actuator chamber. The actuator includes a strike and a magnet, and is pivotable between a first position and a second position relative to the housing. The actuator is also biased towards the first position. The electronic keeper also includes a senor disposed within the battery chamber. When a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor.

First claim

What is claimed is:

1. An electronic keeper comprising:
a housing defining an interior cavity, the housing having a first end, an opposite second end, and a wall;
a face plate coupled to the first end of the housing;
a back plate disposed at the second end of the housing, wherein the wall extends between the face plate and the back plate separating the interior cavity into a battery chamber and a discrete actuator chamber;
an actuator at least partially disposed within the actuator chamber, wherein the actuator comprises a strike and a magnet on opposing ends, wherein the actuator is pivotable between a first position and a second position relative to the housing, and wherein the actuator is biased towards the first position; and
a sensor disposed within the battery chamber, wherein the magnet is positioned proximate the sensor on opposite sides of the wall, and wherein when a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor.

2. The electronic keeper of claim 1 , wherein the battery chamber is sealed to prevent exposure to corrosive conditions.

3. The electronic keeper of claim 1 , wherein the magnet defines an axis, and wherein the axis is substantially parallel to a depth of the wall.

4. The electronic keeper of claim 1 , wherein the face plate defines an opening for access into the actuator chamber.

5. The electronic keeper of claim 4 , wherein the actuator is completely disposed within the actuator chamber, and wherein the strike is positioned proximate the opening.

6. The electronic keeper of claim 5 , wherein the opening is configured to at least partially receive the locking element to contact the strike within the actuator chamber.

7. The electronic keeper of claim 4 , further comprising a strike plate coupled to the face plate opposite the housing and proximate the opening, wherein the strike plate at least partially defines a lock volume configured to at least partially receive the locking element.

8. The electronic keeper of claim 7 , wherein at least the strike of the actuator extends from the actuator chamber and into the lock volume when the actuator is in the first position.

9. The electronic keeper of claim 7 , wherein the actuator further comprises a stop plate that the strike extends from, and wherein when the actuator is in the first position, the stop plate at least partially engages the face plate.

10. The electronic keeper of claim 9 , wherein the actuator further comprises a lever arm extending between the stop plate and the strike.

11. The electronic keeper of claim 7 , wherein when the actuator is in the second position, the strike is completely disposed within the actuator chamber.

12. The electronic keeper of claim 7 , wherein the actuator further comprises a first member having the strike and a second member having the magnet, and wherein the first member is pivotably mounted within the actuator chamber and is pivotable in a first direction from the first position towards the second position, and the second member is pivotably mounted within the actuator chamber and is pivotable in an opposite second direction from the first position towards the second position.

13. The electronic keeper of claim 12 , wherein the first member further comprises a stop plate that the strike extends from, and wherein the stop plate engages with the second member.

14. The electronic keeper of claim 4 , wherein when the actuator is in the first position, the strike is angled to receive the locking element rotating in a first direction, and wherein the first direction is opposite to a second direction that the actuator pivots when moving from the first position towards the second position.

15. The electronic keeper of claim 4 , wherein at least a portion of the back plate is secured to the housing by ultrasonic welding both a butt joint and a shear joint between the housing and the back plate.

16. An electronic keeper comprising:
a first compartment configured to at least partially receive a locking element;
an actuator disposed within the first compartment, wherein the actuator comprises a strike and a magnet on opposing ends, and wherein the strike is configured to contact at least a portion of the locking element and move the magnet from a first position towards a second position;
a second compartment separately sealed from the first compartment at least partially by a wall; and
a sensor disposed within the second compartment and configured to detect the position of the magnet in at least one of the first position and the second position, wherein the magnet is positioned proximate the sensor on opposite sides of the wall.

17. The electronic keeper of claim 16 , wherein the actuator comprises a first member having the strike and a separate second member having the magnet.

18. An electronic keeper comprising:
a housing defining a battery chamber and an actuator chamber;
a face plate coupled to a first end of the housing, wherein the face plate defines an opening for access into the actuator chamber;
an actuator at least partially disposed within the actuator chamber, wherein the actuator comprises a strike and a magnet, wherein the actuator is pivotable between a first position and a second position relative to the housing, and wherein the actuator is biased towards the first position; and
a sensor disposed within the battery chamber, wherein when a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor, and wherein the actuator is completely disposed within the actuator chamber, and wherein the strike is positioned proximate the opening and the magnet is positioned proximate the sensor.
