Abstract

A power supply system for a firearm including a plurality of leads disposed in a rail for providing power to an electric firearm accessory attached thereto and an electric firearm accessory including connectors for electrically connecting to leads disposed in a rail on which the accessory is mounted.

Claims

1. A system for providing power to a firearm accessory, the system comprising:

a plurality of rails attached to a firearm, at least two of the plurality of rails being configured to provide power to the firearm accessory and comprising a positive lead and a ground lead for providing a voltage to the firearm accessory, at least one of the plurality of rails comprising two or more rail sections assembled together to form the at least one of the plurality of rails; and

a power supply electrically connected to the plurality of rails, wherein the power supply provides the voltage to the positive lead of each of the at least two of the plurality of rails, wherein the voltage comprises a plurality of voltages, and wherein at least two of the plurality of voltages are different.

2. The system of claim 1, wherein the power supply comprises a battery disposed within a forearm support disposed at a forearm grip of the firearm, and wherein the forearm support comprises electrical contacts for electrically connecting the battery within the forearm support to the plurality of rails.

3. The system of claim 2, wherein the forearm support is removably connected to the firearm at the forearm grip of the firearm.

4. The system of claim 1, wherein at least one of the plurality of rails comprises a plurality of positive leads and the ground lead, wherein each of the plurality of rails provides one of the plurality of voltages, and wherein the firearm accessory is connected to a first of the plurality of rails to provide a first voltage to the firearm accessory and the firearm accessory is connected to a second of the plurality of rails to provide a second voltage to the firearm accessory.

5. The system of claim 1, wherein at least a portion of at least one of the plurality of rails is formed from an electrically insulating material.

6. The system of claim 1, wherein the power supply comprises a battery having a plurality of terminals, each of the plurality of terminals providing one of a plurality of voltages, and wherein at least two of the plurality of voltages are not equivalent to each other.

7. A powered rail assembly comprising:

a plurality of firearm accessory rails connected to a firearm, each of the plurality of firearm accessory rails comprising a positive lead and a ground lead for creating an electrical circuit between the firearm accessory rail and a firearm accessory, at least one of the plurality of rails comprising two or more rail sections assembled together to form the at least one of the plurality of rails;

a forearm support containing a battery electrically connected to the electrical circuit, the battery being configured to power the electrical accessory via the firearm accessory rail, wherein at least one of the plurality of firearm accessory rails is configured to provide a voltage to the firearm accessory, the voltage being provided by the battery wherein the voltage comprises a plurality of voltages, and wherein at least two of the plurality of voltages are not equivalent to each other.

8. The electrical accessory of claim 7, wherein the electrical accessory is removably attached to the firearm, the attachment being adjustable between a plurality of positions on the firearm.

9. The electrical accessory of claim 7, further comprising a switch for selectively connecting the electronic circuit to the power supply of the firearm.

10. A system for providing power to a firearm accessory connected to a firearm, the system comprising:

a plurality of rails attached to a forearm grip of the firearm, each of at least two of the plurality of rails being configured to provide power to the firearm accessory and comprising a positive lead and a ground lead for providing a voltage at each of the at least two of the plurality of rails, wherein the voltage comprises a plurality of voltages, and wherein at least two of the plurality of voltages are not equivalent to each other, and wherein at least one of the plurality of rails comprises two or more rail sections assembled together to form the at least one of the plurality of rails;

a forearm support connected to the forearm grip of the firearm, the forearm support comprising electrical contacts and being configured for use in supporting the firearm; and

a power supply electrically connected to the plurality of rails, the power supply comprising a battery disposed within the forearm support connected to the forearm grip of the firearm, the power supply providing one or more of the plurality of voltages to the at least two of the plurality of rails.

11. The system of claim 10, wherein the plurality of firearm accessories comprises a flashlight and a sighting device.

12. The system of claim 10, wherein each of the plurality of firearm accessories has a power switch for turning on and off the plurality of firearm accessories.

13. The system of claim 10, further comprising a power switch for simultaneously turning on and off the plurality of firearm accessories.
