Stock Mounted Load Bearing Assembly
Abstract
The invention is an improved load bearing arrangement for use
with firearms. The system comprises a cylindrical body with a
sealing cap, mounting structure on the body including a plurality
of mounting tabs and a "T" rail with matching structure on the
stock. The mounting tabs are only partially fastened on the body so
as to form hooks which will secure the body from behind the
structure on the stock. The "T" rail interfaces with a
corresponding notch on the rear of the stock and is secured with
the stock's butt pad. A water-tight cap is also provided, which is
also capable of removal and replacement without removing the
remaining structure from the stock.

Description
FIELD OF THE INVENTION
[0001] The present invention relates to a carrying and storage
apparatus for firearms and is more particularly related to
cylindrical attachments which have a sliding, T-shaped, mating
feature.
SUMMARY OF THE INVENTION
[0002] In view of the disadvantages inherent in the known types of
magazine follower systems, this invention provides an improved load
bearing system mountable upon a butt stock of a firearm. Its basic
conception is the use of a storage cylinder with at least one "T"
shaped rail and a receptor structure on the stock. The receptor
structure is a "T" shaped slot in the rear of the stock. The
preferred embodiment also features a plurality of broad tabs which
are partially attached to the storage unit along their breadth,
with a matching set of slots in the stock. Once inserted, the
cylinder is slid up the slots towards the fore end of the stock, so
that its hind portion is even with the hind portion of the stock,
and is secured with a butt pad on the stock. In this manner, the
"T" shaped rail is secured with the butt pad and the structure of
its slot and the broad tabs hook behind the outer wall of the
stock, securing the structure to the stock. The storage system is
sealed with a cap, or plug, that provides a water-tight seal and is
easily removed and replaces without removing the entire structure
from the stock.
[0003] The more important features of the invention have thus been
outlined in order that the more detailed description that follows
may be better understood and in order that the present contribution
to the art may better be appreciated. Additional features of the
invention will be described hereinafter and will form the subject
matter of the claims that follow.
[0004] Many objects of this invention will appear from the
following description and appended claims, reference being made to
the accompanying drawings forming a part of this specification
wherein like reference characters designate corresponding parts in
the several views.
[0005] Before explaining at least one embodiment of the invention
in detail, it is to be understood that the invention is not limited
in its application to the details of construction and the
arrangements of the components set forth in the following
description or illustrated in the drawings. The invention is
capable of other embodiments and of being practiced and carried out
in various ways. Also it is to be understood that the phraseology
and terminology employed herein are for the purpose of description
and should not be regarded as limiting.
[0006] As such, those skilled in the art will appreciate that the
conception, upon which this disclosure is based, may readily be
utilized as a basis for the designing of other structures, methods
and systems for carrying out the several purposes of the present
invention. It is important, therefore, that the claims be regarded
as including such equivalent constructions insofar as they do not
depart from the spirit and scope of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] With reference now to the drawings, the preferred embodiment
of the stock mounted load bearing assembly is herein described. It
should be noted that the articles "a", "an" and "the", as used in
this specification, include plural referents unless the content
clearly dictates otherwise.
[0019] With reference to FIGS. 1-4, the present invention is a
storage module 12 mounted upon a gun stock 10. The depicted stock
is an adjustable-for-length stock with a latch 16 (to allow
adjustment) and additional storage 18 (FIGS. 1 & 2). It has a
generally cylindrical body 12 with an open rear end and sealed on a
fore end (FIG. 6). The body 12 is mounted horizontally along the
gun stock 10. Mounting tabs 22 interface with slots 20 (FIG. 7) on
the gun stock 10 to secure the storage module 10 to the stock. The
mounting tabs 22 are, ideally, curved (though any shape that is
capable of allowing interface will suffice) and not completely
fastened to the body 12, forming hooks 32. The body 12 also
features a "T" rail 28 made to interface with a corresponding notch
30 along the rear of the stock 10. As the mounting tabs are slid
into the slots 20, "T" rail 28 is proximate notch 30 (FIGS. 8 &
9). The body 12 is then slid forward (FIGS. 10 & 11), allowing
the hooks to slide behind the wall of the stock body itself
(securing the body 12 from behind), and "T" rail 28 slides into
notch 30 until the body 12 is flush with the rear of the stock 10.
Butt pad 26 is then placed on the stock 10 (FIGS. 4 & 5) and
abuts "T" rail 28, securing the entire body 12 in its forward,
installed position. A plug 14 (FIGS. 1-5) is inserted into the
body's open end to secure it. Ideally the plug is made of a rubber,
plastic or polymer which offers some compressibility so as to
provide a secure and watertight seal. Other materials may be
utilized, but will probably require some form of gasket for
water-tightness and some other securing means. The plug 14 may be
inserted and removed without removing the entire structure from the
stock. The cylindrical body 12 is sized to fit common accessories,
like batteries, and may be any shape, though a round cylindrical
shape would be preferred. The storage body 12 may be made of any
suitable material, such as a metal, plastic or other polymer,
silicone, or composite material. It should be waterproof except for
the one opening, which is sealed by the plug 14.
[0020] Although the present invention has been described with
reference to preferred embodiments, numerous modifications and
variations can be made and still the result will come within the
scope of the invention. No limitation with respect to the specific
embodiments disclosed herein is intended or should be inferred.
