Abstract

The invention comprises an improved recoil control device comprising a bolt head and an inertia block or slider for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages.

Claims

1. A recoil control device for use in a firearm, said device comprising:

a bolt head configured to alternate between a forward position and a rearward position in response to the percussion of one or more cartridges; and

a slider connected to the bolt head and positioned rearward of the bolt head, the slider comprising an oblique slot with a first sloped portion and a second sloped portion, wherein a surface of the bolt head first contacts the first sloped portion and then the second sloped portion when the bolt head moves from a forward to a rearward position;

wherein the bolt head is configured to transmit an impulse to the slider as it alternates between the forward position and the rearward position, the impulse having a component perpendicular to the firing axis of the barrel of the firearm, and wherein the bolt head tilts out of the axis of the firearm barrel at a rearward position, the bolt head comprising a spindle which articulates the bolt head with the slider, the recoil control device further comprising a breech casing comprising a guidance ramp in the form of a groove adapted to accommodate the extremities of the spindle, the guidance ramp being further arranged so that at least the initial backwards movement of the bolt head from the forward position occurs substantially along the axis of the gun barrel, and a slider guide arranged to guide the slider in a movement of translation oblique in relation to the axis of the gun barrel.

2. The recoil control device of claim 1, wherein the bolt head is connected to the slider by a linkage.

3. The recoil control device of claim 2, wherein the linkage comprises a transverse spindle perpendicular to the axis of the gun barrel, the spindle connected to the bolt head and arranged to slide between the first sloped portion, when the bolt head is in the forward position, and the second sloped portion, when the bolt head is in the rearward position.

4. A semiautomatic or automatic firearm comprising the recoil control device of claim 3.

5. The recoil control device of claim 4, wherein the transverse spindle linking the bolt head and the slider is set to have a margin of play in the longitudinal sense.

6. A semiautomatic or automatic firearm comprising the recoil control device of claim 5.

7. The recoil control device of claim 1, wherein the slider guide comprises a sloped rail.

8. A semiautomatic or automatic firearm comprising the recoil control device of claim 7.

9. The recoil control device of claim 7, further comprising a first angle between the sloped rail and the longitudinal axis of the barrel of the gun.

10. The recoil control device of claim 9, wherein the first angle is between about 30 degrees and about 36 degrees.

11. A semiautomatic or automatic firearm comprising the recoil control device of claim 10.

12. The recoil control device of claim 9, further comprising a second angle between the longitudinal axis of the first sloped portion and the sloped rail.

13. The recoil control device of claim 12, wherein the second angle is between about 6 degrees and about 40 degrees.

14. The recoil control device of claim 13, wherein the second angle is between about 24 degrees and about 36 degrees.

15. The recoil control device of claim 1, wherein the breech casing features a cavity, the cavity comprising a forward extremity from which the barrel of the gun extends, a receptacle for a magazine, a forward section that accommodates the bolt head, and a rear section that accommodates the slider and a recovery mechanism.

16. The recoil control device of claim 15, wherein the recovery mechanism comprises a spring.

17. The recoil control device of claim 15, wherein the sides of the breech casing each presents a guide rail for accommodating the respective extremities of the transverse spindle.

18. A semiautomatic or automatic firearm comprising the recoil control device of claim 15.

19. A semiautomatic or automatic firearm comprising the recoil control device of claim 1.
