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 adjustable rail mounting system, comprising:
a rail positioner including a stanchion configured to engage with a recoil groove of a rail system; a first body member configured to receive a first portion of the rail positioner; a second body member configured to receive a second portion of the rail positioner; and a clamping structure configured to couple the first body member and the second body member at a width within a range of widths,
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 the width within the range of widths.

2 . The adjustable rail mounting system of claim 1 , wherein the rail positioner is configured to couple with a first body member and a second body member:
the rail positioner including:
a base extending from a first end to a second end along a first direction, the base further comprising:
a first longitudinal edge that extends from the first end to the second end,
a second longitudinal edge that extends from the first end to the second end, the second longitudinal edge opposite the first longitudinal edge,
a first interference tab protruding from the first longitudinal edge,
a second interference tab protruding from the second longitudinal edge,
a stabilization tab protruding from the second longitudinal edge at a position between the first end and the second end, and
a plurality of teeth extending from the first longitudinal edge at a position between the first end and the second end; and

wherein the stanchion is positioned adjacent the second end, the stanchion extending in a second direction perpendicular to the first direction.

3 . The adjustable rail mounting system of claim 2 , the plurality of teeth further comprising at least three guide teeth.

4 . The adjustable rail mounting system of claim 2 , the first body member having a front end and a rear end, and extending from the front end to the rear end in a third direction, the first body member further including a top portion and a middle portion, the top portion having:
a first rail engagement surface, and a second rail engagement surface; and the middle portion having:
a first inside surface, the first inside surface including:
a plurality of guide grooves couplable with the plurality of teeth, and
an interference tab slot extending from the front end to the rear end in the third direction and configured to receive the first interference tab,
a second inside surface that extends in a fourth direction perpendicular to the third direction, the second inside surface configured to planarly engage with a portion of a bottom surface of the rail positioner, and
a third inside surface, the third inside surface extending from the second inside surface in a fifth direction perpendicular from the fourth direction, terminating at a bottom portion, the bottom portion having:
an inside surface, the inside surface extending in the fifth direction, and
a bottom surface, the bottom surface extending from the inside surface to an outside surface.

5 . The adjustable rail mounting system of claim 4 , the outside surface further comprising a third rail engagement surface and a fourth rail engagement surface.

6 . The adjustable rail mounting system of claim 4 , the third inside surface is configured to extend around an optical device.

7 . The adjustable rail mounting system of claim 4 , wherein the outside surface of the bottom portion of the second body member further includes a first rail engagement surface and a second rail engagement surface.

8 . The adjustable rail mounting system of claim 2 , the second body member having a front end and a rear end, and extending from the front end to the rear end in a sixth direction, the second body member also including a top portion and a middle portion, the top portion having:
a first rail engagement surface, and a second rail engagement surface, and the middle portion having:
a first inside surface, the first inside surface including:
a stabilization tab slot extending from the front end to the rear end in the sixth direction and configured to receive the stabilization tab, and
an interference tab slot extending from the front end to the rear end in the sixth direction and configured to receive the second interference tab,

a second inside surface that extends in a seventh direction transverse to the sixth direction, the second inside surface configured to planarly engage with a portion of a bottom surface of the rail positioner, and
a third inside surface, the third inside surface extending from the second inside surface in a seventh direction transverse to the sixth direction, terminating at a bottom portion, wherein the third inside surface of the second body member is configured to planarly engage with the middle portion of the first body member, the bottom portion having:
an inside surface, the inside surface extending in the seventh direction, wherein the inside surface of the bottom portion of the second body member is configured to planarly engage with the bottom portion of the first body member; and
a bottom surface, the bottom surface extending from the inside surface to an outside surface.

9 . The adjustable rail mounting system of claim 8 , wherein the outside surface further comprises a third rail engagement surface and a fourth rail.

10 . The adjustable rail mounting system of claim 8 , wherein the third inside surface of the second body member is configured to extend around an optical device.
