Gunstock

Abstract

The action and barrel of a firearm are in direct contact with a high modulus of elasticity holder that receives the vibrations of recoil directly and distributes the vibrations over a wide area. The high modulus of elasticity holder, which may be made of a metal such as aluminum, transfers the forces to the wooden portion of a wooden gunstock over a wide area greater than 12 square inches so that there are substantially no concentrated stresses placed upon the wood.

Description

RELATED CASES [0001] This application is a continuation-in-part application of U.S. patent application Ser. No. 10 / 914,792 filed Aug. 10, 2004, in the name of Gerald Robert Thompson, which application is a continuation-in-part application of U.S. provisional patent application No. 60 / 494,138 filed Aug. 11, 2003, by inventor, Gerald Robert Thompson. The benefit of provisional patent application No. 60 / 494,138 is claimed.BACKGROUND OF THE INVENTION [0002] This invention relates to gunstocks. [0003] It is known for long barrel firearms such as rifles to have wooden gunstocks or gunstocks made of synthetic such as plastic or gunstocks comprising a metal platform with a synthetic portion of the stock formed onto it. For example, in one known embodiment, a metal platform is attached to the synthetic portion of the stock as a metal insert in the cavity of an injection molding apparatus to have the synthetic portion of the stock molded onto it. [0004] Wood stocks, without a metal insert hav...

AI Technical Summary

Benefits of technology

[0008] It is a still further object of the invention to provide a novel gunstock which is more durable and delivers less of a recoil to the shooter.

[0024] From the above description, it can be understood that the firearm of this invention has several advantages, such as for example: (1) the high modulus of elasticity holder holds the wood stock or bamboo stock against warping from moisture over a period of time; (2) the high modulus of elasticity holder reduces failure from weaknesses in the wood stock or bamboo stock; (3) the high modulus of elasticity holder reduces harmonics and subharmonics in the wood stock or bamboo stock after rounds are fired; (4) the high modulus of elasticity holder reduces failure in the woods from concentrated recoil forces; (5) the high modulus of elasticity holder dissipates the concentrated forces that are occurring when the firearm is fired over a wider area and applies forces that are to be transmitted to the wood stock or bamboo stock in less concentrated form over the wide area; and (6) it does not have fasteners extending from the breech into the wood stock or bamboo stock to apply concentrated forces to the wood stock or bamboo stock and loosen the fasteners.

Problems solved by technology

Wood stocks, without a metal insert have several disadvantages, such as for example: (1) there are small microscopic openings that in time admit some moisture causing eventual warping; (2) laminates may have voids that weaken the stock and permit eventual failure; (3) wood is subject to harmonics and subharmonics of the barrel vibrations after each round is fired; (4) the strength of the wood is not predictable and failure of the wood can be sudden and unexpected; (5) in the normal manufacturing of laminates, for reasons of economy, the adhesives used are sprayed in a continuous process of specific volume of adhesive per unit area, whereas the voids that need to be filled are irregular and, thus, some voids do not get filled; (6) many wood stocks have very small areas of contact with the barrel that must adsorb the entire force of recoil thus increasing the pressure on the points of contact; (7) the forces imposed on the wood stock near the breech area of the firearm by fasteners cause damaging stress on the wood; (8) because of the lack of good dimensional stability, cross lamination is difficult; and (9) the formation of wood sheets for lamination causes stress and damage to the cellulose fiber of the wood, thus weakening it.

Synthetic stocks without an insert and with an insert molded into the synthetic also have disadvantages such as imparting a sharper more concentrated kick because the recoil force tends to impact the shooter close in time with vibrations from resonance effects.
