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 firearm comprising:

a barrel defining the longitudinal axis of the barrel and having a forward end and a rearward end, where a cartridge is loaded at the rearward end;

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

a slider connected to the bolt head, the slider comprising a sloped surface to contact a linkage to the bolt head;

wherein the slider is positioned forward of or at the same position as the bolt head relative to the barrel when the bolt head rests at its forward position, and wherein the rearward movement of the bolt head forces the slider to move downward and below the longitudinal axis of the barrel upon firing.

2. The firearm of claim 1, wherein the sloped surface of the slider is comprised within a slot of the slider and the bolt head comprises a tenon, and wherein the tenon moves within the slot to force the downward movement of the slider.

3. The firearm of claim 2, wherein the slot contains contain a double-angled surface comprising at least two regions of the slot each having a surface with a different angle relative to the longitudinal axis of the barrel, and wherein the tenon contacts the at least two regions of the slot.

4. The firearm of claim 1, further comprising a bolt head guide 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 transverse to the longitudinal axis of the barrel.

5. The firearm of claim 4, wherein the slider guide comprises a sloped surface.

6. The firearm of claim 3, further comprising a bolt head guide 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 transverse to the longitudinal axis of the barrel.

7. The firearm of claim 6, wherein the slider guide comprises a sloped surface.

8. The firearm of claim 1, further comprising a housing, the housing 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 the slider, and a rear section that accommodates the bolt head at its rearward position.

9. The firearm of claim 8,wherein the sides of the housing presents a guide rail for accommodating the movement of the slider.

10. The firearm of claim 9, wherein the guide rail forms a straight line.

11. The firearm of claim 9, wherein the guide rail forms a curved line.
