Gun assembly including gun action mated to gunstock by at least three zones of intentional interference fit

摘要

A gun assembly comprising a cylindrical gun action mated within a generally semi-cylindrical cavity of a synthetic gunstock to thereby define a specialized interference fit between the gunstock and the gun action is disclosed herein. The innovative gun assembly comprises at least three zones of interference fit established by assembling together a synthetic gunstock that includes a specialized receiving cavity generally in the form of a semi-cylinder and defined by a first radius R1 (correspond to zone surfaces) and a second radius R2 (corresponds to relief surfaces); and a metallic gun action generally in the form of a cylinder defined by a third radius R3. In order to achieve the specialized interference fit, the length of the third radius is selected to be slightly greater than the length of the first radius.

主权项

1. A gun assembly comprising:
a gunstock made of a synthetic material, the gunstock having a cavity that defines a cavity wall surface; a gun action made of a selected metal or metal alloy, the gun action having a cylindrically shaped outer wall surface and a central axis; and a gun barrel connected to the gun action along the central axis; characterized in that the gun action is mated within the cavity of the gunstock so as to define an interference fit between the gunstock and the gun action, wherein the interference fit comprises at least three distinct zones of intentional deformation between the synthetic material of the gunstock and the metal or metal alloy of the gun action, wherein two of the at least three zones of intentional deformation are diametrically opposed or are nearly diametrically opposed to each other along a horizontal plane that is coextensive with the central axis of the gun action, and wherein a third zone of the at least three zones of intentional deformation is positioned equidistant between the two other zones of intentional deformation, wherein the third zone of the at least three zones of intentional deformation is separated from the two other zones of intentional deformation by way of respective first and second reliefs positioned along the cavity wall surface of the gunstock on either side of the third zone.
