The present invention is a modular handgrip for rifles and other long
guns. The handgrip features a base with a locking dovetail rail on a
first side and a second opposite side configured to receive a rail. Back
strap additions are provided capable of receiving the rail on the body,
which are customizable to a user's preferences while fore straps are
provided with rails in a similar manner. Also provided is a storage
compartment inside the main body, accessible from a bottom of the grip.
As such, an organization, such as an armory, can provide a number of
customizable options for handgrips while only stocking a basic grip and a
number of optional modules at lower unit and storage costs. Of particular
note is a modular fore strap design with an integrated trigger guard.
1. A fore strap for a modular handgrip comprising:A body with structure
for interface with a modular handgrip; andA trigger guard extension,
cantileverally attached to the body at an upper fore end of the same.

FIELD OF THE INVENTION
The present invention relates to handgrips for rifles and more particularly relates to a modular handgrip, which may be modified to the personal preferences of a user.
BACKGROUND OF THE INVENTION
Handgrips for rifles are well known in the prior art and are found in many different styles, shapes and designs. Most are not protected by any particular intellectual property protection and most that are have design patents for their ornamental features. Those that have utility patents, or their foreign equivalents, focus on one feature of the handgrip that is novel, like hidden compartments or support tangs. With the variety of handgrips, it becomes very difficult for larger organizations, such as law enforcement and military units, to equip individualized grips, which increase performance efficiency, for large numbers of members. As a result, a standardized weapon is issued and any improvements must be, if allowed, purchased and fitted by the receiving member. What is needed, therefore, is a handgrip that is both standardized and simultaneously customizable in an efficient manner. To this end, the modular grip of the present invention fills the need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of handgrips, this invention provides an improved modular handgrip. As such, the present invention's general purpose is to provide a new and improved handgrip that will be customizable for a user with a lower production cost and more efficient modification process.
The basic modular handgrip comprises a base grip section that is generally oblong. On the shorter, opposite sides of the base grip body is a rail on the hind side and a rail-receiving trough on the fore side. Back straps of varying designs are provided, each with a rail-receiving trough for the base grip body's rail. These slide together and are joined with a detent system. Fore straps are also provided with a rail design that allows them to slide into the base grip body's rail-receiving trough and are secured in a similar manner. In an alternate embodiment, a storage compartment may be made in the base grip body's interior, accessible from the underside, which is held in a similar detent lock. After assembly, pieces may be secured with an adhesive or epoxy or some similar material or left in their locked state for later modification. Fore and back straps may be provided in any configuration imaginable to meet a user's preferences.
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.
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.
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.
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.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an exploded view of the handgrip according to the present invention showing several module options.
FIGS. 2a - 2g are side plan views of the handgrip according to the present invention when assembled with different modules.
FIG. 3a is a lower perspective view of the handgrip of FIG. 2c.
FIG. 3b is a rear perspective view of the handgrip of FIG. 2a.
FIG. 4 is the handgrip of FIG. 1 from a different perspective view.
FIG. 5 is a perspective view of the handgrip according to the present invention installed on a rifle's lower receiver.
FIG. 6 is a side elevation of the assembly of FIG. 5, showing different hind strap possibilities.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, the preferred embodiment of the modular handgrip 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.
Referring now to FIGS. 1 and 4, the handgrip comprises a base grip body 2, with an attachment rail 4 and an attachment trough 7. Back straps 14 a, 14b and 14c attach to body 2 by sliding unto rail 4 and are secured in place by interfacing with detent 5. Alternatively, a living hinge or roll pin may be used to alternately secure the back strap to grip body 2. Rail 4 and body 2 both feature tongue-in-groove manufacture (not shown due to size) to hold either back straps 14a, 14b, or 14c, in place, shown in FIGS. 3a and 3b. Back straps 14a, 14b, 14c may also be further secured with an adhesive for a permanent attachment. Fore straps 12a, 12b slide into trough 7 and are secured when the grip body 2 is bolted to a lower receiver, shown in FIG. 5, through bore 9, shown in FIG. 3a. Ideally, body 2 is also hollow with cavity 8, which accommodates storage closure 10. Closure 10 is also held with a detent or may be secured by another means, such as a locking tab feature.
As seen in FIGS. 2 and 6, the actual shapes of the fore and back straps are limitless, being customizable to the whim of the user. As such, the ornamental design of the straps should not be seen as either limiting of the claims or of the possible combinations that could be designed yet still fall within the scope of this invention
Although the present invention has been described with reference to preferred embodiments, numerous modifications and variations can be made, including the fashioning of different shapes and styles of handgrip base bodies, fore straps and back straps and still the result will come within the scope of the invention. One particularly novel fore strap is labeled as 12a and includes a built in trigger guard. No limitation with respect to the specific embodiments disclosed herein is intended or should be inferred.
