Abstract

Embodiments of the application can include an integrated rail system construction for a firearm with transverse ribs or tabs (e.g., picatinny rail) to include an undercut or slot at a front and/or rear face to cooperate with mounting structure for a detachable accessory. Embodiments of a rail structure can include a channel to pass wires used to power accessories mounted to the rail. Embodiments of the application can include methods for manufacturing an integral rail system.

Claims

1. An accessory mount for a firearm having a longitudinal barrel, the accessory mount comprising:

a longitudinal mount body having a front end and a rear end, said mount body to couple to the firearm over a portion of the barrel;

longitudinally spaced transverse ribs along said mount body;

a conduit passing through a plurality of the transverse ribs;

a power supply unit comprising,

a first end to connect to a power source exterior to said accessory mount,

a second end to connect to an accessory mounted to selected transverse ribs; and

an electrical connection unit between said first end and said second end of the power supply unit, the electrical connection unit disposed in the conduit;

wherein the conduit is accessible in a recess between adjacent transverse ribs, wherein the recess has a curved lower surface;

wherein the conduit is insulatingly accessible in an anchor slot in a lateral face of at least one transverse rib;

wherein the anchor slot comprises an insulator configured to reciprocate between a first position to insulate the electrical connection unit in the conduit and a second position to allow access to the electrical connection unit in the conduit.

4. The accessory mount of claim 1, wherein the electrical connection unit is configured to pass through at least ¼

of the transverse ribs, at least ½

of the transverse ribs, at least ¾

of the transverse ribs, or all the transverse ribs.

8. The accessory mount of claim 1, wherein the conduit is accessible in selected recesses between said transverse ribs, the accessory mount body comprising:

insulators in remaining recesses between said transverse ribs to cover corresponding anchor slots in said remaining recesses or bottom surfaces of said remaining recesses.

9. The accessory mount of claim 1, wherein the conduit comprises a plurality of conduit units.

10. The accessory mount of claim 9, wherein each conduit unit is a prescribed radial distance from a top surface of the transverse ribs.

11. The accessory mount of claim 9, wherein each conduit unit passes through different numbers of said transverse ribs.

12. The accessory mount of claim 9, wherein said conduit units comprise at least three conduit units having substantially equal cross-sectional dimensions configured to extend through the a plurality of the transverse ribs, wherein at least three insulated cables are respectively provided one in each of said at least three conduit units to supply at least three different voltage levels, such that each of the at least three conduit units carries an insulated cable with a different voltage level.

13. The accessory mount of claim 9, wherein each conduit unit includes one of a rectangular recessed configuration, a recessed teardrop configuration, an inner mounting surface accessible to an exterior surface of a corresponding transverse rib, or the inner mounting surface with a connecting passage to an exterior surface of the mount body.

15. The accessory mount of claim 1, wherein the accessory mount comprises at least one accessory rail, said at least one accessory rail comprising a MIL-STD-1913 rail.

16. The accessory mount of claim 15, said at least one accessory rail comprising:

opposing longitudinally extending side grooves adjacent the transverse ribs, the side grooves to define external reference surfaces for mounting accessories; and

a longitudinally extending central groove between the side grooves, the central groove to define internal reference surfaces for mounting accessories.

6. An accessory mount for a firearm having a barrel, the accessory mount comprising:

a longitudinal mount body having a front end and a rear end, said mount body to couple to the firearm over a portion of the barrel;

longitudinally spaced transverse ribs along said mount body, the plurality of ribs comprising a first transverse rib and an adjacent transverse rib, wherein a first lateral face of the first transverse rib faces an opposing lateral face of the adjacent transverse rib; and

a conduit passing through a plurality of the transverse ribs, wherein the conduit is accessible in an anchor slot positioned in the first lateral face of the first transverse rib facing the opposing lateral face of the adjacent transverse rib.

7. The accessory mount of claim 6, wherein the anchor slot comprises an insulator configured to reciprocate between a first position to insulate the electrical connection unit in the conduit and a second position to allow access to the electrical connection unit in the conduit.

14. An accessory mount for a firearm having a longitudinal barrel, the accessory mount comprising:

a longitudinal mount body having a front end and a rear end, said mount body to couple to the firearm over a portion of the barrel;

longitudinally spaced transverse ribs along said mount body; and

a conduit passing through a plurality of the transverse ribs;

wherein the conduit includes a recess configured to extend to an inner radial surface of the transverse ribs.

2. The accessory mount of claim 14, comprising:

a power supply unit comprising,

a first end to connect to a power source exterior to said accessory mount,

a second end to connect to an accessory mounted to selected transverse ribs; and

an electrical connection unit between said first end and said second end of the power supply unit, the electrical connection unit disposed in the conduit.

3. The accessory mount of claim 2, wherein the electrical connection unit comprises an insulated data cable in the conduit.

5. The accessory mount of claim 2, wherein the conduit is accessible in a recess between adjacent transverse ribs, wherein the recess has a curved lower surface.

17. An accessory mount for a firearm including a barrel, the accessory mount comprising:

a tubular body mounted over a portion of the barrel substantially coaxially and in a transversely spaced relationship;

at least one accessory rail at a predetermined position of the tubular body, said at least one rail including a plurality of longitudinally spaced ribs for mounting an accessory;

a curved lower surface between longitudinally spaced ribs;

at least one longitudinal passageway to define an interior surface in a lateral surface of a rib of the tubular body; and

an insulated conductive line insulated with an epoxy coating disposed in the passageway.

18. The accessory mount for a firearm of claim 17, wherein said insulated conductive line is configured to pass electrical signals representative of data.

19. A method comprising:

forming a plurality of accessory mount locations extending along a surface of an accessory rail;

forming an accessory rail system for a firearm including the accessory rail, wherein forming the accessory rail system comprises both milling operations and rotating operations comprising rotating the rail system unitary body against a material removing tool; and

providing an integrated electrical wiring assembly extending within the accessory rail system to pass through the accessory rail to the accessory mount locations.
