3,514,889 CUSHIONED FIREARM RECOIL PAD Frank Arl'achmayr, 1220 S. Grand Ave., Los Angeles, Calif. 90015 Filed Apr. 15, 1968, Ser. No. 721,361 Int. Cl. F41c 23/00 US. Cl. 4274 3 Claims ABSTRACT OF THE DISCLOSURE A construction for imparting supported compression cushioning to the terminal portions of a firearm recoil pad the body of which is molded of solid rubber, by the formation of foam rubber-filled recesses within the end portions of the body.
SUMMARY OF THE INVENTION This invention relates to improvements in firearm recoil pads which in use are applied to the end faces of gun stocks, such pads commonly being molded of rubher and shaped in conformity with the gun stock.
Recoil pads with which the invention is concerned have elongated bodies molded of solid rubber, and may contain any of various internal recess or void configurations to lend cushioning compressibility to the otherwise solid rubber body. Such configurations usually are employed to cushion the body extent intermediate its ends and range from various forms including side or internal voids in predetermined patterns and extents, any of which in general may be incorporated in pads additionally cushioned in accordance with the present invention.
Commonly, the end extents of prior pads have been solid throughout and therefore lacking in terminal cushioning compressibility, a condition that for some usages may be productive of considerable recoil discomfortto the user.
My general object is to provide for internal cushioning of one or both end portions of the pad imparting internal compressibility to the pad body in a manner that will be productive of yield to recoil forces while otherwise giving such internal support that will maintain the normal body shape.
Briefly, this objective is accomplished by the provision of foam rubber-filled recesses within the padends, the properties of the foam rubber being selectable, largely in terms of void size and content to respond in cushioning effect while giving internal support to the body rubber at the locations of the recesses.
The invention will be more fully understood from the following detailed description of an illustrative embodiment shown by the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of the recoil pad with a portion broken away to expose the foam rubber fill at one end;
FIG. 2 isa side elevation of FIG. 1; and
FIGS. 3 and 4 are end elevations as viewed respectively from lines 3 -3 and 44 of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENTS In its general characteristics, the pad structure is shown to comprise a natural or synthetic solid rubber united States Patent 3,514,889 Patented June 2, 1970 body 10 molded to the illustrated configuration for conformity to gun stock shape, the body 10 being bonded to the relatively hard rubber base lamination 11 which is secured by conventional means to the end face of a gun stock.
The invention is primarily concerned with internal cushioning of the end portions of the body 10, and as previously indicated, any suitable means such as internal recess or void configurations, not shown, or side voiding as at 12, may be employed to render the body between its end portions 13 and 14 compressible in cushioning response to gun recoil forces.
In accomplishment of the object of compressively cushioning with internal restorative support an end extent or both end portions of the body, the latter is internally recessed at 15 to receive a foam rubber fill 16 which is integrated by cementing, or otherwise, with the solid body rubber and with the exposed surface of the fill contoured to the terminal body curvature. The recess 15 desirably may occupy at least one-half the thickness of the body 10, as substantially in the relation illustrated, and although variable in shape, the recess practicably may be formed to open transversely through the body to the depth of the surface at 17.
The qualities of the foam rubber fill 16 may be selected, as in terms of its port size and distribution, to have the desired compressibility and cushioning of the body in response to recoil forces, and to have such full elastic restorability as will maintain the normal pad shape. Foam rubbers are known for their compressive and restorative properties, and selection is readily within the capabilities of those familiar with the art and foam rubber compositions.
As Will be apparent, a user of the pad is spared by the foam rubber compressibility of what otherwise might be sharp impact through solid rubber at the end or ends of the pad, and assurance of indefinite maintenance of the pad shape in that it remains internally and restoratively supported.
1. A firearm recoil pad for application to a gun stock comprising an elongated body molded of solid rubber bonded to a base lamination and having within one end a single recess extending transversely through the body and filled with exposed foam rubber, said foam rubber in the recess occupying at least one-half the body thickness at the recess.
2. A recoil pad according to claim 1, in which the foam rubber is exposed at its surface curving in conformity with the curvature of the body.
3. A recoil pad according to claim 2, in which said foam rubber in the recess is spaced from said base lamination.
