Firearm with recoil mitigation
View Patent ↗Firearms with recoil mitigation have a frame with a connected slide, the slide configured to reciprocate relative to the frame along a slide reciprocation path, the slide having a ramp surface angularly offset from the slide reciprocation path by a first angle, a follower element connected to the frame and configured to reciprocate with respect to the frame along a follower path, the follower being biased toward the slide, and the follower having a slide contact portion configured to contact the ramp surface of the slide, such that reciprocation of the slide generates reciprocation of the follower element. The reciprocation of the slide may define a horizontal plane. The ramp surface may face downwardly and rearwardly. The slide may include a top panel and opposed downwardly-depending side panels each having lower edges. The ramp surface may be formed in a cutout above the lower edge of a side panel.
1. A firearm comprising:
a frame;
a slide connected to the frame;
the slide configured to reciprocate relative to the frame along a slide reciprocation path;
the slide having a ramp surface angularly offset from the slide reciprocation path by a first angle;
a follower element connected to the frame and configured to reciprocate along a linear follower path with respect to the frame;
the follower being biased toward the slide;
the follower having a slide contact portion configured to contact the ramp surface of the slide, such that reciprocation of the slide generates reciprocation of the follower element; and
wherein the follower path is angularly offset from the slide reciprocation path.
2. The firearm of claim 1 wherein the reciprocation of the slide defines a horizontal plane, and the ramp surface faces downwardly and rearwardly.
3. The firearm of claim 1 wherein the slide includes a top panel and opposed downwardly-depending side panels each having lower edges, and wherein the ramp surface is formed in a cutout above the lower edge of one of the side panels.
4. The firearm of claim 3 wherein the frame includes an upwardly extending cover element covering the cutout.
5. The firearm of claim 3 including a cutout on each side panel.
6. The firearm of claim 1 wherein the ramp surface is angularly offset from the slide reciprocation path by between 10 and 45 degrees.
7. The firearm of claim 1 wherein the ramp surface is a straight line.
8. The firearm of claim 1 wherein the follower element has a mass of at least 200 g.
9. The firearm of claim 1 wherein the follower element is biased with a spring force between 70 N and 116 N.
10. The firearm of claim 1 wherein the follower path is perpendicular to the ramp surface.
11. The firearm of claim 1 wherein the follower element has a mass at least 50% of a mass of the slide.
12. The firearm of claim 1 wherein the frame includes a grip defining a grip axis and wherein the follower path is parallel to the grip axis.
13. The firearm of claim 1 wherein the frame defines a trigger area and wherein the follower element is forward of the trigger area.
14. The firearm of claim 1 wherein the frame defines a trigger area and wherein the follower is adjacent to the trigger area.
15. A firearm comprising:
a frame;
a slide connected to the frame;
the slide configured to reciprocate relative to the frame along a slide reciprocation path;
the slide having a ramp surface angularly offset from the slide reciprocation path by a first angle;
a follower element connected to the frame and configured to reciprocate with respect to the frame along a follower path; the follower being biased toward the slide;
the follower element having a top;
the top having a channel dividing the top into a left ear and a right ear;
each of the left ear and right ear having a slide contact portion; and
the slide contact portions are configured to contact the ramp surface of the slide, such that reciprocation of the slide generates reciprocation of the follower element.
