Description




TECHNICAL FIELD




The present invention relates generally to rifles, and more particularly to rifle periscopes for attachment to rifles and providing an indirect line of vision.




BACKGROUND OF THE INVENTION




Rifle periscopes are known for providing users with an indirect line of vision for viewing surrounding areas without exposing the users to those areas or any persons within those areas. In addition, the indirect line of vision also allows the users to fire their rifles from protected positions.




Current rifle periscopes are mounted on the rifles in a manner that permits the users to utilize existing sight assemblies integrated within the rifles. A drawback of these rifle periscopes is that they obstruct normal use of the sight assemblies when the users wish to take a direct line of vision ordinarily taken when the users do not have to seek cover. In other words, a part of the periscope may block at least one of the sight assemblies. Furthermore, some rifle periscopes require the simultaneous use of two or more movable mirrors. As a result, the design of the periscope is somewhat complicated thereby increasing manufacturing time and costs associated therewith.




Therefore, it would be desirable to provide a rifle periscope having a simple structure that provides for an indirect line of vision without obstructing the use of existing sight assemblies integrated within the rifle.




SUMMARY OF THE INVENTION




The present invention provides a rifle periscope that allows for an indirect line of vision without obstructing normal use of existing sight assemblies integrated within the rifle.




The rifle periscope includes a removable mount assembly for attachment to the barrel of a rifle in a manner that allows for an unobstructed direct line of vision when using the sight assemblies. The removable mount assembly has a first surface and a second surface. The first surface has a viewing mirror attached thereto for providing an indirect line of vision that is outside of a firing range of the rifle. The second surface has a targeting mirror attached thereto for providing an indirect line of vision that is within a firing range of the rifle.




One advantage of the present invention is that a user may view the surrounding area from a protected position without exposing himself to any threats within the viewed area.




Another advantage of the present invention is that a user may fire his rifle from a protected position without exposing himself to the target or other persons in the surrounding area.




Yet another advantage of the present invention is that the rifle periscope does not obstruct a direct line of vision when making normal use of the sight assemblies integrated within the rifle.











Other advantages of the present invention will become apparent when viewed in light of the detailed description of the preferred embodiment when taken in conjunction with the attached drawings and appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT




In the following figures, the same reference numerals are used to identify the same components in the various views.




Referring to

FIGS. 1 and 2

, there are generally shown views of a rifle


10


with a rifle periscope


30


mounted thereon, in accordance with a preferred embodiment of the present invention. The rifle


10


preferably is a military rifle having a trigger


12


adjacent to a pistol grip


14


. The pistol grip


14


is intended to provide the user with a handhold for maintaining control of the rifle


10


while he pulls the trigger


12


.




The rifle


10


also preferably includes a forestock


16


that is intended to provide a handhold for the user's other hand. Of course, the pistol grip


14


and forestock


16


may be used to handle the rifle


10


in various circumstances other than while firing the rifle


10


.




The rifle


10


further includes a front sight assembly


18


and a rear sight windage drum


20


for aiming at a target. The user may aim the rifle


10


by taking a direct line of vision with the front sight assembly


18


and the rear sight windage drum


20


. In other words, the user may align the front sight assembly


18


with the rear sight windage drum


20


on the desired target.




The rifle


10


has a barrel


22


that directs rounds of ammunition when they are fired from the rifle


10


. As best shown in

FIG. 2

, the rifle periscope


30


is mounted on a portion of the barrel


22


in manner that does not obstruct a direct line of vision taken with the front sight assembly


18


and the rear windage drum


20


. In particular, the rifle periscope


30


is preferably mounted on the barrel


22


between the front sight assembly


18


and a flash suppressor


24


of the rifle


10


. However, it is understood that the rifle periscope


30


may be secured to other suitable portions of the rifle


10


that allow the user to view and fire the rifle


10


from protected positions.




Although

FIGS. 1 and 2

show a military rifle, it is understood that the rifle periscope


30


may be used for various other types of rifles.




Referring primarily to

FIGS. 3A and 3B

, there are shown, respectively, a perspective view and an exploded view of the rifle periscope


30


, in accordance with a preferred embodiment of the present invention. The rifle periscope


30


includes a removable mount assembly


32


for attachment to the barrel


22


of the rifle


10


.




In the preferred embodiment, the removable mount assembly


32


includes a mirror base


34


having a curved surface


36


(as best shown in

FIG. 4

) for mating to the bare


22


of the rifle


10


. The removable mount assembly


32


preferably also includes a backing plate


38


that has an opposing curved surface


40


for mating to the barrel


22


. The mirror base


34


and the backing plate


38


preferably are both comprised of aluminum. However, it is understood that the mirror base


34


and/or the backing plate


38


can instead be made of plastic, nylon, rubber or a variety of other suitable materials.




Preferably, the removable mount assembly


32


is secured to the barrel


22


by attaching the backing plate


38


to the mirror base


34


in a manner that clamps the barrel


22


between the curved surface


36


of the mirror base


34


and the opposing curved surface


40


of the backing plate


38


.




The backing plate


38


is preferably engaged to the mirror base


34


by a plurality of screw fasteners


42


. The screw fasteners


42


are inserted through openings


44


formed in the backing plate


38


and thereafter fastened to threaded holes


46


formed in the mirror base


34


.




Of course, the rifle periscope


30


may be attached to the barrel


22


of the rifle


10


by a variety of other suitable fasteners. For example, in an alternative embodiment, a snap-fit engagement between the backing plate


38


and the mirror base


34


may allow for easier attachment and detachment of the rifle periscope


30


from the barrel


22


. Moreover, a mere strap may be used to secure the rifle periscope


30


to the barrel


22


. It is understood that various other fasteners may be used to attach the rifle periscope


30


to the barrel


22


.




The mirror base


34


preferably has a first surface


48


intended to receive a viewing mirror


50


. As best shown in

FIG. 5

, the viewing mirror


50


is positioned in a manner that provides the user with an indirect line of vision for safely viewing objects that are beyond a firing range of the rifle


10


. The viewing mirror


50


may be made of aluminum, plastic, or other suitable materials that provide sufficient reflection.




Furthermore, the rifle periscope


30


may be rotated about a longitudinal axis of the barrel


22


thereby permitting the user to employ the rifle periscope


12


for viewing surrounding areas in various circumstances. In this regard, the rifle periscope


30


may be rotated at an angle


26


from the horizon (as shown in FIG.


1


). There are at least two situations in which the user may wish to rotate the rifle periscope


30


.




First, the user may wish to have an indirect line of vision for viewing surrounding areas at a similar height level as the user's eyes. For example, a user holding the rifle


10


near eye level may only need to rotate the rifle periscope


30


a relatively small angle from the horizon. In contrast, a user holding the rifle near waist level may need to rotate the rifle periscope at a larger angle from the horizon.




In another situation, the user may rotate the rifle periscope


30


at various angles for viewing above or below the level of his eyes. For example, a user may rotate the rifle periscope at a relatively large angle to have an indirect line of vision for viewing an object or person located uphill.




Referring to

FIGS. 3A

,


3


B, and


6


, the mirror base


34


also includes a second surface


52


intended to receive a targeting mirror


54


. The targeting mirror


54


is positioned on the barrel


22


in a manner that provides the user with an indirect line of vision for aiming and firing at a target. Preferably, the targeting mirror


54


is positioned about


45


degrees from a longitudinal axis of the barrel


22


so as to allow the user to aim and fire the rifle


10


from a side of the rifle


10


. Similar to the viewing mirror


50


, the targeting mirror


54


may be made of aluminum, plastic, or other suitable materials that provide sufficient reflection.




The targeting mirror


54


preferably has one or more markings for providing the user with a periscope sight. The periscope sight allows the user to aim and fire his rifle


10


at a target from a protected position. These markings preferably include a flash suppressor profile line


56


and a center bore line


58


. The flash suppressor profile line


56


and the center bore line


58


intersect at an intersection point


60


intended to serve as the periscope sight.




The user preferably holds the rifle


10


sideways to aim and fire the rifle


10


. In particular, the user may hold the forestock


16


in his upwardly facing left palm and grasp the pistol grip


14


with the fingers of his right hand (as shown in FIG.


6


).




The user may then utilize the targeting mirror


54


to aim the rifle


10


. This is accomplished by positioning the rifle


10


in a manner that allows the user to see that the flash suppressor profile line


56


is outlining the actual profile of the flash suppressor


24


. Simultaneously, the user may train the intersection point


60


on the desired target thereby aiming the rifle


10


at that target. The user may then pull the trigger


12


with the thumb on his right hand.




Although this example demonstrates a user holding a rifle


10


for shooting a target positioned to his left, it is understood that the user may utilize a similar technique for shooting a target positioned to his right. Preferably, the intersection point


60


serves as the periscope sight as long as the user sees that the flash suppressor profile line


56


outlines the actual profile of the flash suppressor


24


.




Referring now to

FIG. 7

, in the preferred embodiment, the rifle periscope also includes a cover


62


intended to conceal the viewing mirror


50


and the targeting mirror


54


when they are not in use. The cover


62


is preferably secured to the removable mount assembly


32


by a compression fit and alternatively by a snap fit or various other suitable fastening methods.




Furthermore, the cover


62


preferably is attached to the removable mount assembly by a cord


64


so as to dangle the cover


62


therefrom when it is not being used to conceal the viewing mirror


50


and the targeting mirror


54


. In particular, the mirror base


34


preferably has a recess


66


formed therein (as best shown in

FIG. 4

) for receiving an anchor


68


integrated within an end of the cord


64


. The anchor


68


is held within the recess


66


when the curved surface


36


of the mirror base


34


is mated to the barrel


22


.




While particular embodiments of the invention have been shown and described, numerous variations and alternate embodiments will occur to those skilled in the art. Accordingly, it is intended that the invention be limited only in terms of the appended claims.
