Support structure for a weapons system

1. A support structure for a weapons system comprising:

a frame adapted for connection to a wearer;

the frame having an elongated first portion defining a frame axis and adapted for positioning adjacent to the spine of the wearer;

the frame having an upper end;

a boom connected to the upper end of the frame and having a first boom portion extending away from the frame, and a second boom portion angled with respect to the first boom portion and extending away from the frame axis;

the boom having a free end;

a cable reel mechanism connected to the frame;

a cable having a first end connected to the cable reel mechanism and a free end extending from the free end of the boom and adapted to connect to the weapons system;

the cable reel mechanism including a biasing facility to exert tension on the cable, such that tension on the cable provides support for the weapons system,

the second boom portion having a cable support wheel spaced apart from the free end; and

a spacer having an arcuate guide surface for contacting the cable proximate the free end and forward of the cable support wheel, the spacer having an arcuate guide surface for contacting the cable adapted to limit the upward angle of the cable.

2. The support structure of claim 1 wherein the free end of the boom includes a cable support element, and wherein the free end of the cable extends from the cable support element to the weapons system and remains spaced apart from the boom.

3. The support structure of claim 2 wherein the free end of the boom defines an exit aperture through which the cable passes, the exit aperture facing at least partly away from the axis, such that the cable may angle away from the frame without contacting the boom.

4. The support structure of claim 1 wherein the free end of the boom is open in a forward direction away from the axis, such that the cable may extend away from the frame at an angle.

5. The support structure of claim 4 wherein the angle is at least 30 degrees from the frame axis.

6. The support structure of claim 1 wherein the cable reel mechanism includes a pair of pneumatic springs.

7. The support structure of claim 6 including a cable take-up mechanism between the springs.

8. The support structure of claim 1 wherein the cable reel mechanism includes a plurality of pulleys supporting the cable.

9. The support structure of claim 1 wherein the cable reel mechanism includes a block and tackle mechanism of limited length providing an extended range of cable payout length relative to the limited length of the block and tackle mechanism.

10. The support structure of claim 1 wherein the frame includes a facility for connection to the back of the wearer, and wherein the free end of the cable is operable to connect to an intermediate portion of a weapons system, and to urge the weapons system to exert a compressive force on the chest of the wearer.

11. The support structure of claim 1 wherein the frame includes a facility for connection to the back of the wearer, and wherein the boom extends forward on a medial plane of the wearer.

12. The support structure of claim 1 wherein the weapons system is selected from the group consisting of rifles, medium machine guns, and heavy machine guns.

13. The support structure of claim 1 wherein the cable support element is above a centerline axis of the cable support wheel.

14. The support structure of claim 1 wherein the cable support wheel and cable support element define an exit aperture for the cable.

15. The support structure of claim 14 wherein the exit aperture is open forward.

16. The support structure of claim 14 wherein the exit aperture is open forward and downward.

17. The support structure of claim 14 wherein the exit aperture faces at least partly away from the frame axis.

18. A support structure for a weapons system comprising:

a frame adapted for connection to a wearer;

the frame having an elongated first portion defining a frame axis and adapted for positioning adjacent to the spine of the wearer;

the frame having an upper end; a boom connected to the upper end of the frame and having a first boom portion extending away from the frame, and a second boom portion angled with respect to the first boom portion and extending away from the frame axis;

the boom having a free end; a cable reel mechanism connected to the frame;

a cable having a first end connected to the cable reel mechanism and a free end extending from the free end of the boom and adapted to connect to the weapons system;

the cable reel mechanism including a biasing facility to exert tension on the cable, such that tension on the cable provides support for the weapons system;

the cable reel mechanism includes a pair of elongated pneumatic springs each with a first end connected to the frame and a opposed movable second end;

a cable take-up mechanism between the springs and having a first pulley connected to the first ends of the springs, and an opposed second end connected to the second ends of the springs; and

an elongated tubular housing defining an elongated passage receiving the cable reel mechanism.

19. The support structure of claim 18 wherein the housing is a flat body having a selected width and a limited thickness less than the width such that is it adapted for positioning along a wearer's spine.

20. The support structure of claim 18 wherein the pneumatic springs operate in compression to bias apart the cable reel mechanism.
