Abstract

Devices mountable to a rail having a recoil groove are provided. In one aspect a device mountable to a rail having a recoil groove has a rail positioner having a longitudinal length with a plurality of teeth arranged along an edge of the longitudinal length and a recoil groove insert extending away from the rail positioner and configured to be inserted into the recoil groove, a first body member having a first rail engagement surface and plurality of openings generally sized to receive the plurality of teeth and arranged along a length of the first body a second body member having a second rail engagement surface opposite the first body member, and a clamping structure operable to tighten and maintain a clamping force between the first body member and the second body member when the rail positioner is arranged in therein and that can be released facilitate installation and removal of the mounting to a rail.

First claim

What is claimed is:

1. An electronic device configured to mount to a firearm rail that includes a recoil groove, comprising:
a rail positioner including (i) a first engagement surface and (ii) a second engagement surface configured to be inserted into the recoil groove;
a first body member including (i) a third engagement surface and (ii) a fourth engagement surface configured to interface with the first engagement surface;
a second body member including a fifth engagement surface opposite the first body member; and
a clamping structure operable to tighten and maintain a clamping force across a range of widths between the first body member and the second body member against the rail positioner and the firearm rail arranged therein,
wherein the rail positioner is adapted to flex to maintain a tight fit between the first body member and the second body member when the first body member and the second body member are separated by a width within the range of widths.

2. The electronic device of claim 1 , wherein the rail positioner further comprises at least one tab on an edge of the rail positioner that is opposite from the first engagement surface, the fifth engagement surface configured to receive the tab as the tab extends along a length of the second body member.

3. The electronic device of claim 2 , wherein the first body member includes a first land portion extending laterally from a portion of the first body member below the fourth engagement surface toward the second body member.

4. The electronic device of claim 3 , wherein the second body member includes a second land portion extending laterally from a portion of the second body member below the fifth engagement surface toward the first body member.

5. The electronic device of claim 4 , wherein at least one of the first land portion and second land portion includes a slope configured to direct the rail positioner along a path that is upward of at least one of the first land portion and the second land portion when the rail positioner is arranged to engage a surface proximate a forward end of the electronic device.

6. The electronic device of claim 4 , wherein at least one of the first land portion and the second land portion includes a slope configured to direct the rail positioner along a path that is upward of at least one of the first land portion and the second land portion when the rail positioner is arranged to engage openings proximate a forward end of the electronic device to create a bias pressure at the second engagement surface.

7. The electronic device of claim 4 , wherein at least one of the first land portion and the second land portion includes a slope configured to direct the rail positioner along a path that is upward of at least one of first land portion and second land portion when the rail positioner is arranged to engage a surface proximate a forward end of the electronic device to close any gaps between the second engagement surface and the firearm rail.

8. The electronic device of claim 3 , wherein the rail positioner is configured to be positioned at least in part proximate and adjacent to the first land portion when positioned between the first body member and the second body member.

9. The electronic device of claim 8 , wherein the rail positioner includes protrusions that extend both outwardly and downwardly from the edge of a longitudinal length and wherein the first land portion includes grooves therein to receive and guide the fourth engagement surface into contact with the first engagement surface.

10. The electronic device of claim 1 , wherein the clamping structure comprises:
a member integrally formed in one of the first and second body members and adapted to receive a screw; and
an opening in the other one of the first and second body members through which only a threaded portion of the screw fits.

11. The electronic device of claim 1 , wherein the first engagement surface comprises a plurality of openings, and wherein a separation of the plurality of openings is greater than 8 openings per inch.

12. An electronic device configured to mount to a rail that includes a recoil groove, comprising:
a rail positioner including (i) a first engagement surface on a length of the rail positioner and (ii) a second engagement surface configured to be inserted into the recoil groove;
a first body member including (i) a third engagement surface and (ii) a fourth engagement surface configured to interface with the first engagement surface;
a second body member including a fifth engagement surface opposite the first body member;
a user control at a position along at least one of the length of the first body member and a length of the second body member; and
a clamping structure configured (i) to move the first body member and the second body member to clamp against the rail positioner and the rail with a clamping force and (ii) to release the clamping force,
wherein the rail positioner is configured to be clamped with the first engagement surface coupled with at least a first portion of the fourth engagement surface in a first position to position the recoil groove insert at a first longitudinal length from the user control, and
wherein the rail positioner is configured to be clamped with the first engagement surface coupled with at least a second portion of the fourth engagement surface in a second position to position the recoil groove insert at a second longitudinal length from the user control, the second longitudinal length being different from the first longitudinal length.

13. The electronic device of claim 12 , wherein the rail includes a plurality of recoil grooves arranged at a recoil groove pitch along a rail length and the fourth engagement surface has a pitch along a length of the first body member that is greater than a pitch of the plurality of recoil grooves.

14. The electronic device of claim 12 , wherein a pitch of the fourth engagement surface is between six openings per inch and eight openings per inch.
