Benefits of technology

The present invention provides a way to move without changing the angle at which something is attached. This helps to keep things organized and in the correct place.

Problems solved by technology

Problematically, these adjustments and calculations assume that the rifle is held perfectly vertical.
A significant problem is induced if a rifle is fired when the rifle plane, which is the plane that includes the line of sight and the bore axis, is not in the vertical plane, defined as the plane including the line of sight and a line from the center of the earth to the end of the rifle's bore.
The windage error becomes an order of magnitude larger when shooting at an elevated target.
Another issue faced by long-distance riflemen is that, in real life situations, there is typically no reference to the true horizon.
If the shooter is on uneven ground and / or is aiming towards a non-horizontal background, the human physiology is not able to determine the position of the vertical plane with any degree of precision and significant unintentional canting of the rifle is to be expected.
Classic bipods do not allow for cant angle adjustment, their legs are either in a stored or deployed orientation.
There are, however, bipods available that offer adjustment of cant and swivel angles, however, these angles may not be adjusted independently in the majority of such designs.
In such designs, however, once the cant angle has been adjusted, subsequent use of the swiveling functionality will modify the cant angle if the legs are not in the horizontal position, inducing cant error.
Furthermore the cant adjustment mechanism of such designs relies on an unstable equilibrium concept: if loosened, gravity will cause the firearm being supported to tilt or fall to the side.

first embodiment

[0086]FIG. 4A represents a main body assembly 200. The main body assembly 200 may include an opening with two concentric surfaces 212 and two angulated leg pivot surfaces 220. Mounting assembly 100 includes a mounting mechanism to attach mounting assembly 100 to a firearm, for example via a rail 400. Rail mounting mechanisms will be described below.

[0087]FIG. 4B represents a first embodiment of mounting assembly 100, featuring a quick disconnect rail mounting mechanism.

second embodiment

[0088]FIG. 6A represents mounting assembly 100, featuring a permanent rail mounting mechanism.

third embodiment

[0089]FIGS. 14A and 14B represent mounting assembly 100, featuring a cant locking plate 130L integrating a level indicator. Level indicators will be further discussed below. Mounting assembly 100 also includes a cant guide projection 122 featuring two concentric surfaces 122A. Concentric surfaces 122A and concentric surfaces 212 are all concentric with cant axis 1. The dimensional tolerances of surfaces 122A and 212 should allow a smooth rotation of mounting assembly 100 in main body assembly 200. For ease of operation it is desirable that the cant axis 1 be concentric or close to concentric with the rifle bore.

[0090]Now referring to the cant angle lock mechanism with captive thumb screw, as depicted in FIG. 4B, mounting assembly 100 further includes a clamp surface 125, a cant locking plate 130 or 130L and a cant locking thumb screw 140.

[0091]When the user of such an embodiment has selected a cant angle, such angle, in embodiments, may be locked by clamping main body assembly surfa...

Abstract

The present disclosure relates to a firearm support, comprising a main body assembly, at least two legs operably attached to the main body assembly, a mounting assembly comprising an attachment mechanism configured to enable attachment of a firearm to the mounting assembly and a swivel mechanism configured to control an angular rotation about a swivel axis; and a cant mechanism configured to control an angular rotation about a cant axis by rotating the mounting assembly along an opening in the main body assembly, whereby cant angle may be locked and remain constant as an attached firearm swivels.

Description

FIELD OF THE INVENTION[0001]This disclosure relates to firearm supports, and, more particularly, to bipods enabling independent cant and swivel adjustments and level measurement capabilities.BACKGROUND OF THE INVENTION[0002]In a typical mid to long range shooting application, a firearm may be equipped with an optical sighting device (i.e. a sight or scope) mounted above the rifle's bore.[0003]To reach long distance targets, elevation compensation is used to counteract the gravitational pull of the Earth on a projectile. As depicted in FIG. 1A, the bore axis is aimed at a point above the intended target, causing the bullet trajectory to cross the line of sight to the target a first time as the bullet is in an upwards flight path and a second time as it is descending, being pulled by gravity. The angle between the bore axis and the line of sight used to reach distant targets is referred to as the holdover angle (hereinafter β).[0004]Before proceeding, it is worth noting that when a sc...
