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 power rail system comprising:

a first accessory rail attached to a firearm, the first accessory rail comprising a first positive lead disposed at an external surface of the first accessory rail and extending along a length of the first accessory rail, and a first ground lead disposed at the external surface of the first accessory rail and extending along the length of the first accessory rail;

a second accessory rail attached to the firearm, the second accessory rail comprising a second positive lead disposed at an external surface of the second accessory rail and extending along a length of the second accessory rail, and a second ground lead disposed at the external surface of the second accessory rail and extending along the length of the second accessory rail;

a third accessory rail attached to the firearm; and

a battery connected to the third accessory rail, the battery being electrically connected via the third accessory rail to the first positive lead, the second positive lead, the first ground lead, and the second ground lead to provide a voltage to the first accessory rail and the second accessory rail.

2. The power rail system of claim 1, wherein the first accessory rail further comprises a third positive lead.

3. The power rail system of claim 2, wherein the battery is connected to the first positive lead, the third positive lead, and the first ground lead to provide a plurality of voltages to the first accessory rail.

4. The power rail system of claim 3, wherein the plurality of voltages comprises a first voltage and a second voltage.

5. The power rail system of claim 4, wherein the first voltage and the second voltage are different from one another.

6. The power rail system of claim 1, wherein the first accessory rail is formed from an electrically insulating material, and wherein the first positive lead is insulated from the first ground lead by the accessory rail.

7. The power rail system of claim 1, wherein the first accessory rail is formed from a conductive material, wherein the first ground lead is formed as a portion of the first accessory rail, and wherein the first positive lead is insulated from the first accessory rail by an insulating material.

8. The power rail system of claim 1, wherein the battery comprises a plurality of positive terminals, and wherein each of the plurality of positive terminals provides a different voltage.

9. The power rail system of claim 1, wherein each of the first positive lead, the second positive lead, the first ground lead, and the second ground lead are continuous, and wherein an electric accessory connected to the first accessory rail or the second accessory rail at any location along respective lengths of the first accessory rail or the second accessory rail is powered by the battery.

10. The power rail system of claim 1, further comprising a fourth accessory rail attached to the forearm of the firearm, the fourth accessory rail comprising a fourth positive lead disposed at an external surface of the fourth accessory rail and extending along a length of the fourth accessory rail, and a third ground lead disposed at the external surface of the fourth accessory rail and extending along the length of the fourth accessory rail.

11. A power rail system comprising:

a first accessory rail attached to a forearm of a firearm, the first accessory rail being formed from an electrically insulating material and comprising a first continuous positive lead disposed at an external surface of the first accessory rail and extending along a length of the first accessory rail, a second continuous positive lead disposed at the external surface of the first accessory rail and extending along the external surface of the first accessory rail, and a first continuous ground lead disposed at the external surface of the first accessory rail and extending along the length of the first accessory rail, wherein the first continuous ground lead is insulated from the first positive lead and the second positive lead, and wherein an electric accessory can be attached to the first continuous positive lead, the second continuous positive lead, or the first continuous ground lead at any location along the length of the first accessory rail;

a second accessory rail attached to the forearm of the firearm, the second accessory rail comprising a third continuous positive lead disposed at an external surface of the second accessory rail and extending along a length of the second accessory rail, and a second continuous ground lead disposed at the external surface of the second accessory rail and extending along the length of the second accessory rail, wherein the electric accessory can be attached to the third continuous positive lead and the second continuous ground lead at any location along the length of the second accessory rail;

a third accessory rail attached to the firearm; and

a battery connected to the third accessory rail, the battery being electrically connected via the third accessory rail to

the first continuous ground lead and at least one of the first continuous positive lead or the second continuous positive lead and to provide a first voltage to the first accessory rail, and

the second continuous ground lead and the third continuous positive lead and to provide a second voltage to the second accessory rail.

12. The power rail system of claim 11, wherein the first voltage is different from the second voltage.

13. The power rail system of claim 11, wherein the first voltage and the second voltage are equivalent.

14. A power rail system comprising:

a first accessory rail attached to a forearm of a firearm, the first accessory rail comprising a first positive lead disposed at an external surface of the first accessory rail and extending along a length of the first accessory rail, and a first ground lead disposed at the external surface of the first accessory rail and extending along the length of the first accessory rail;

a second accessory rail attached to the forearm of the firearm, the second accessory rail comprising a second positive lead disposed at an external surface of the second accessory rail and extending along a length of the second accessory rail, and a second ground lead disposed at the external surface of the second accessory rail and extending along the length of the second accessory rail;

a third accessory rail attached to the forearm of the firearm, the third accessory rail comprising a third positive lead disposed at an external surface of the third accessory rail and extending along a length of the third accessory rail, and a third ground lead disposed at the external surface of the third accessory rail and extending along the length of the third accessory rail;

a fourth accessory rail attached to the forearm of the firearm; and

a battery connected to the fourth accessory rail, the battery being electrically connected via the fourth accessory rail to the first positive lead, the second positive lead, the third positive lead, the first ground lead, the second ground lead, and the third ground lead to provide a voltage to the first accessory rail, the second accessory rail, and the third accessory rail.

15. The power rail system of claim 14, wherein the first accessory rail further comprises a fourth positive lead.

16. The power rail system of claim 15, wherein the battery is connected to the first positive lead, the fourth positive lead, and the first ground lead to provide a plurality of voltages to the first accessory rail.

17. The power rail system of claim 16, wherein the plurality of voltages comprises at least a first voltage and a second voltage.

18. The power rail system of claim 17, wherein the first voltage is different from the second voltage.
