Abstract

A powered door accessory system generally includes a powered door accessory assembly, a generator, and a power storage device. In an embodiment, the powered door accessory assembly includes an electric drive and a driven member operatively connected to the electric drive. The generator is in electrical communication with the electric drive of the powered door accessory assembly and the power storage device. A method for operating a door accessory assembly is also disclosed.

Claims

1. A powered door accessory system comprising:

a powered door accessory assembly configured to mount to at least one of an associated door and an associated structure adjacent the associated door;

a generator configured to mount to at least one of the associated door and the associated structure adjacent the associated door and configured to generate an electrical current in response to movement of the associated door, the generator being in electrical communication with the powered door accessory assembly;

a power storage device in electrical communication with the generator and the powered door accessory assembly.

2. The system of claim 1, wherein the powered door accessory assembly comprises at least one of a powered door latch actuator, a powered lock assembly, an electric door opener, a push plate actuator, a card reader, an electronic eye, a motion detector and biometric reader.

3. The system of claim 1, wherein the generator includes a coil of wire mounted to the associated door and a magnet mounted adjacent the associated door, whereby movement of the associated door results in movement of the coil of wire in relation to the magnet.

4. The system of claim 1, wherein the generator includes a magnet mounted to the associated door and a coil of wire mounted adjacent the associated door, whereby movement of the associated door results in movement of the magnet in relation to the coil of wire.

5. The system of claim 1, wherein the generator includes a magnet and a coil of wire and the system further comprising a movable member operatively connected to the associated door and at least one of the magnet and the coil of wire.

6. The system of claim 5, wherein the movable member comprises at least one of a gear, a sprocket, a shaft, a cam, a plunger, a piston rod, a cable, a pulley, a linkage, an arm and a wheel.

7. The system of claim 6, wherein the movable member is operably connected to a biasing member.

8. The system of claim 6, wherein the movable member is operably connected to a plurality of gears.

9. The system of claim 1, wherein the powered door accessory assembly comprises an automated door lock configured to mount to the associated door, and the generator being configured to mount to the associated door.

10. The system of claim 1, wherein the door latch assembly comprises an automated door latch actuator configured to mount to or adjacent a doorjamb for the associated door and the generator is configured to mount to or adjacent a door jamb for the associated door.

11. The system of claim 1, wherein the power storage device comprises a capacitor.

12. The system of claim 1, wherein the power storage device comprises a battery.

13. A method for powering a door accessory assembly comprising:

mounting at least one of a magnet and a coil of wire to a door;

moving at least one of the coil of wire and the magnet in relation to each other by moving the door to develop an electrical current and the voltage in the coil of wire; and

delivering the electrical current to the door accessory assembly.

14. The method of claim 13, wherein the mounting step comprises mounting the coil of wire to the door, the method further comprising placing a magnetic fixture including the magnet adjacent the door.

15. The method of claim 13, further comprising storing the voltage developed in the coil of wire in a power storage device.

16. A powered door accessory system comprising:

a powered door accessory assembly configured to mount to at least one of an associated door and an associated structure adjacent the associated door;

a coil of wire configured to mount to at least one of the associated door and the associated structure adjacent the associated door, the coil of wire being in electrical communication with the powered door accessory assembly; and

a magnet configured to mount to at least one of the associated door and the associated structure adjacent the associated door, the magnet and the coil of wire cooperating with one another such that movement of the associated door results in movement of the magnet in relation to the coil of wire, or vice versa, whereby an electrical current is developed in the coil of wire.

17. The system of claim 16, further comprising a power storage device in electrical communication with the coil of wire and the powered door accessory assembly.

18. The system of claim 17, further comprising a switch in electrical communication with the power storage device and the powered door accessory assembly, the switch being configured to control the delivery of power to the powered door accessory assembly from the power storage device.

19. The system of claim 18, further comprising a signal receiver in electrical communication with the switch.

20. The system of claim 18, further comprising a regulator disposed between and in electrical communication with the power storage device and the powered door accessory assembly.

21. The system of claim 16, wherein the powered door accessory assembly includes an electric drive and a driven member operatively connected to the electric drive, the driven member being configured to cooperate with at least one of a door latch member and a door latch bolt receptacle for the associated door, the driven member being moveable between an extended position and a retracted position, where the driven member is configured to cooperate with the door latch member the driven member being configured such that when the driven member is in the extended position the driven member engages a door latch member for the associated door to displace the door latch member from a door latch receptacle and when the driven member is in the retracted position the driven member is at least partially disposed in the door latch receptacle, and where the driven member is configured to cooperate with the door latch bolt receptacle the driven member being configured such that when the driven member is in the extended position the driven member is at least partially received in the door latch bolt receptacle and when the driven member is in the retracted position the driven member removed from the door latch bolt receptacle.
