Description




FIELD OF THE INVENTION




The present invention relates to a gunsight system for a firearm allowing faster target acquisition and providing a more precise aiming point. More particularly, the system utilizes a plurality of light gathering means to accurately define an aiming point while providing immediate target acquisition.




BACKGROUND OF THE INVENTION




During the years, firearm sights have been improved consistently to provide a user more accuracy under nearly all conditions. The use of reflective materials, light-gathering flourescent fibers and fiber optics have been utilized to design highly visible gun sights under all conditions, including low-light.




U.S. Pat. No. 5,878,503 (the '503 Patent) to Howe et al., and assigned to the assignee of the present application, discloses a high visibility gun sight system for detachable mounting on a gun barrel. The system uses a light-gathering plastic rod to provide a highly visible gun sight in low light conditions. As taught by the '503 Patent, the gun sight system, including the plastic rod, is mounted on an upper surface of a gun barrel in line with a raised bead sight normally manufactured near a distal end of the gun barrel. The plastic rod thereby instantly attracts a user's focus under circumstances that the raised bead will not.




U.S. Pat. No. 5,638,604 (the '604 Patent) to Lorocco discloses various configurations of sighting devices for projectile type weapons. Each design configuration employs light-gathering flourescent fiber to gather and amplify natural light. In one embodiment illustrated in FIG. 14 of the '604 Patent, three individual light-gathering fibers form a sight plane for aiming within a scope housing. Set screws permit said light-gathering fibers to be adjusted within the scope housing.




While the '503 and '604 Patents disclose useful gun sights, the need exists to implement a gun sight system, for all firearms most notably a shotgun with a ventilated ribbed barrel, able to accurately define an aiming point while allowing immediate target acquisition. The present invention utilizes a front and rear sight each including light-gathering means to define a precise aiming point providing immediate target acquisition. Triangular ends of said light-gathering means viewable by a user clearly define an aiming point.




SUMMARY OF THE INVENTION




The system of the present invention includes a rear and front sight each having colored light-gathering means as known in the art. Said front sight comprises a base member, retaining an elongated light-gathering rod, mounted to a gun barrel spaced from a muzzle end of said gun barrel. One end of said light-gathering rod viewable by a user is in the shape of a triangle directed upward.




The rear sight comprises a housing, with a retaining member for retaining an oval-shaped light-gathering rod with two ends, mounted to the gun barrel spaced rearward of said front sight. Said ends of the oval-shaped pipe define an aiming plane within a void bounded by said housing. Each end of the oval-shaped pipe viewable by the user is formed in the shape of a triangle in planar alignment with one another.




The front and rear sights are aligned such that the three pipe triangles define a precise aiming point for the user. From the user's perspective, an upper point of the front triangle aligned flush with an imaginary line joining the rear triangles results in an accurate shot. However, both the front and rear sights include adjustable means to implement the most accurate configuration and alignment of triangles considering all circumstances.

DETAILED DESCRIPTION




Reference is now made to the figures wherein like parts are referred to by like numerals throughout.

FIGS. 1 and 2

show the present invention mounted on a gun barrel


10


including a front sight


30


and a rear sight


50


. In a preferred embodiment, the sights


30


,


50


are mounted to a ventilated rib


68


extending along a top edge of the barrel


10


.




The front sight


30


includes a base member


35


having spaced stirrups


40


extending upwardly from an upper surface thereof. Said stirrups


40


define a longitudinal passage therethrough for detachably securing a first light gathering tube or rod means


45


. Three stirrups


40


are spaced apart along the length of the plastic rod and positioned such that they hold and support the plastic rod in a plane parallel to the longitudinal axis of the gun barrel


10


and in proper alignment with the longitudinal axis of the barrel


10


.




Said base member


35


is mounted to the top edge of the barrel


10


, spaced from a front end thereof, by means of a screw


36


inserted through a base member opening


36


, having a countersink to receive a head of the screw


36


, and then inserted and tightened by means of screw


36


threads into the rib


68


securing the base member


35


. A commercially available compound known as Loctite® my be used in conjunction with the screw


36


or double-sided tape may be applied along the underside of the base member


35


to further secure the base member


35


.




Said base member


35


preferably slopes upward 1½° toward a front end of the base member


35


. The slight slope is designed to prevent the pressure created by the attachment means at the front end of the base member


35


from forcing the rearward end of the base member


35


above the gun barrel


10


. The slightest fluctuation in the position of the base member


35


will reduce the accuracy of the gun sight system.




In a preferred embodiment, the first light-gathering means


45


comprises a length of solid cylindrical colored plastic rod which is light-transparent. Preferably the exterior surface of the plastic rod is very smooth or polished. The forward end


31


of the plastic rod is preferably a sloped planer end. The rearward end or viewing end


32


of the plastic rod is triangular shaped and preferably has a planer surface which is a matte or slightly roughened surface.




The plastic rod can be formed from a variety of well-known plastics such as acrylics, nylon, polycarbonate, polystyrene, etc. in which a soluble colored dye is included. In general terms, any self-supporting light-transparent plastic may be used for this purpose.




Preferably the upper surface of the base member


35


includes a longitudinal recess or groove for guiding the plastic rod when the plastic rod is being slidably inserted beneath the stirrups


40


on the base member


35


. A stop member


38


at a forward end of the base member


35


serves to prevent the plastic rod from being pushed too far forwardly on the base member. It also prevents the forward end of the plastic rod from catching or snagging on brush, weeds, twigs, etc.




Since the plastic rod is detachable from the base member


35


, it is very easy to install different plastic rods whenever that is necessary or desirable. Different colored plastic rods may be more effective in differing light conditions. Further, different sized triangular viewing ends


32


of the plastic rod provide a means for adjusting the elevation of the front sight


30


to account for vertical firing inaccuracies. Therefore, the interchangeable rods are used to effectively calibrate the firing of the gun in a vertical plane.




Now referring to

FIGS. 3

,


4


,


5


,


6


and


7


the rear sight


50


comprises a housing


55


, a retainer member


70


and a second light-gathering means


65


. Said housing


55


, including a first leg


57


and a second leg


60


, defines a V-shaped void


77


. Said first leg


57


includes two openings


56


, spaced from a bottom surface thereof, having countersinks to receive heads of bolts


58


which extend through openings


56


and then through vents


66


of rib


68


and insert through corresponding openings


59


spaced from a bottom surface of the second leg


60


such that a nut may be applied thereto, causing said legs


57


,


60


to detachably engage opposite sides of rib


68


.




The second light-gathering means


65


is comprised of the same material, with the same properties, as the first light-gathering means


45


described above. However, the second light-gathering means


65


comprises a semi-oval plastic rod with two ends


67


each triangular in shape defining a planar space therebetween. The two triangular-shaped ends


67


project, when installed, in the rearward direction such that the ends


67


are offset from a plane defined by the semi-oval plastic rod. Without departing from the scope of the present invention, the ends


67


can also be implemented within the plane defined by the semi-oval plastic rod. In other words, it is not imperative that the ends “project” in the rearward direction but they need only face in the rearward direction. As with the first light-gathering means


45


, viewable surfaces of ends


67


preferably have a planer surface which is a matte or slightly roughened surface.




Upon installation, said semi-oval plastic rod seats in groove


69


that traverses the perimeter of retaining member


70


that inserts into a recess


75


in the housing


55


. The retaining member


70


has the overall shape of the semi-oval plastic rod such that, while seated in groove


69


, the plastic rod circumscribes the retaining member


70


. As required, the recess


75


allows a majority of the oval-shaped plastic rod to be exposed to light.




A rectangular planar surface


72


extending from an upper surface of said retaining member


70


, includes an opening


73


, having a countersink, for insertion of a screw


74


therethrough and into opening


75


in said housing thereby securing the retaining member


70


and the second light-gathering means


65


to the housing


55


. The planar surface


72


is accommodated by a rectangular notch


76


on an upper surface of the housing


55


. Said notch


76


has a greater length that the planar surface


72


allowing the retaining member


70


to be shifted laterally for reasons described hereinafter. To facilitate the lateral shift of the retaining member


70


, said opening


73


is oval-shaped and larger than a head of screw


74


permitting screw


74


to be properly aligned with opening


75


even though the retaining member


70


may have been shifted laterally.




Now referring to

FIG. 8

, when mounted together, each end


67


of the oval-shaped plastic rod of the rear sight


50


extends into the V-shaped void


77


from opposite directions to define a planar space therebetween. Except for the triangular ends


67


, the housing


55


and arms


78


of the retaining member


70


conceal the oval-shaped plastic rod from a rearward view so as to quickly focus a firearm user's attention to the triangular ends


67


.




Besides protecting the oval-shaped plastic rod of the rear sight


50


from breakage, the retaining member


70


also allows for lateral shifting of the oval-shaped plastic rod. Further, lateral shifting of the oval-shaped plastic rod provides a means for accounting for horizontal firing inaccuracies. Therefore, the shifting means is used to effectively calibrate the firing of the gun in a horizontal plane.




From a firearm user's view, the two sights


30


,


50


and their respective light-gathering means


45


,


65


provide three viewable lighted triangular surfaces defining a precise aiming point. During use, the lighted triangles quickly draw the attention of a firearm user providing quick target acquisition and firing capability.




In a preferred embodiment, the present invention is designed to hunt turkey. The turkey's frame is unique in that the head is remotely located from the turkey's body by an elongated neck. Turkey hunters desire to kill turkeys with head shots and therefore require a gun sight with supreme accuracy. Turkeys rarely remain still further requiring means to quickly acquire precise aim on the turkey's head. The present invention provides the needed accuracy and immediate target acquisition necessary to effectively hunt turkeys. While well-suited for turkey hunting, the gun sight system disclosed herein is effective for hunting all varieties of game.




Although the gun sight system is shown implemented on a ventilated ribbed barrel


10


, it is to be understood that the gun sight system of the present invention is equally efficient with all firearms, including those with non-ribbed barrels. Moreover, the base member


35


, housing


55


and the retainer member


70


are preferably fabricated of nylon but said components may be fabricated of any plastic, metal, alloy, polymer, etc.




Although the invention has been described in detail with reference to the preferred embodiment, additional variations and modifications exist within the scope and spirit of the invention as described and defined in the following claims.
