Leveling jack for a gun sight of a rifle

Abstract

A leveling jack for a gun sight (or ‘scope’) of a gun or rifle is provided. The leveling jack is movable between at least a first and a second position and is secured to a gun or rifle. The leveling jack has a bottom edge which may be secured to, for example, the picatinny rail of the top of the gun or rifle and an extended bar which contacts and levels the gun sight. The leveling jack may also be secured directly to the gun or rifle without utilizing a picatinny rail. The leveling jack is especially suitable for leveling the gun sight of the gun or rifle in a quick and efficient manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) A leveling jack for a gun sight (or ‘scope’) of a gun or rifle is provided. The leveling jack is movable between at least a first and a second position and is secured to a gun or rifle. The leveling jack has a bottom edge which may be secured to, for example, the picatinny rail of the top of the gun or rifle and an extended bar which contacts and levels the gun sight. The leveling jack may also be secured directly to the gun or rifle without utilizing a picatinny rail. The leveling jack is especially suitable for leveling the gun sight of the gun or rifle in a quick and efficient manner.

(8) Referring first to FIG. 1, in an embodiment a leveling jack 1 for a gun sight 10 is provided. The leveling jack 1 may have a top 2, a bottom 3, a first side 4, a second side 5 a front 6 and a back 7. The bottom 3 of the leveling jack 1 may be secured to a gun or rifle 100 (FIG. 4). In one embodiment, the device 1 is secured to a barrel 20 of a gun or rifle 100 (FIG. 4). The front 6/top 2 of the leveling jack 1 may contact and level a bottom 11 of the gun sight 10 as described below.

(9) In an embodiment, the first side 4 and/or second side 5 of the leveling jack 1 may have an extended knob 30. The extended knob 30 may take on various embodiments, including a short knob (FIG. 1) or a handle (FIG. 2), both of which operate in the same manner. The extended knob 30 may allow a user to control the leveling jack 1 so as to position and level the gun sight 10 in the proper alignment. The extended knob 30 may be, for example, generally cylindrical (and may have a rough edge for better griping and turning). Passing through the extended knob 30 may be a pivot pin 40. The extended knob 30 and the pivot pin 40 may be located at the back 7 of the leveling jack 1 and may allow the front 6 of the leveling jack 1 to rotate upward and downward with respect to the back 7 of the leveling jack 1 which remains stationary.

(10) The pivot pin 40 may allow the leveling jack 1 to pivot so that the front 6 of the leveling jack 1 may rotate upward or downward between a first position (FIG. 1 to a second position as shown in FIG. 2). The front 6 of the leveling jack 1 may have an extended bar 80. Preferably, the extended bar 80 is cylindrical, so as to always contact the bottom 11 of the gun sight 10 in a flush manner. In particular, the extended bar 80 may be the portion of the leveling jack 1 that actually contacts and aligns the bottom 11 of the gun sight 10 so as to level the gun sight 10. In one embodiment, the extended bar 80 is cylindrical and may rotate around an internal pin so that the leveling jack 1 does not slightly alter the leveling of the sight 10 as the sight 10 is pushed upward into the level position while using the leveling jack 1.

(11) In one embodiment, the leveling jack 1 may be secured to a picatinny rail 300 of the gun or rifle 100 (although it may also be secured directly to the gun or rifle in an embodiment). In an embodiment, a user may move the leveling jack 1 horizontally and may secure the leveling jack 1 to various locations on the picatinny rail 300. In particular, the leveling jack 1 may be selectively attached to different rails 375 of the picatinny rail 300 to better align the leveling jack 1 with respect to the bottom 11 of the gun sight 10. In alternative embodiments, the device 1 may be secured to a gun or file by use of, for example, straps, magnets, rings or securing strips as opposed to utilizing a picatinny rail 300 (which may not be present on the gun or rifle).

(12) Typically, with prior art gun sights, when a gun sight 10 is secured to a gun or rifle 100, a user typically must try to adjust the gun sight by hand to make sure the gun sight is level with respect to the barrel of the gun or rifle. FIGS. 1 and 3 illustrate how the gun sight 10 is not level as attached in those figures. Leveling the gun sight 10 by hand is not always easy or accurate. Accordingly, the present leveling jack 1 allows a user to easily and quickly level the gun sight 10 with respect to the gun or rifle 100. In particular, when the gun sight 10 is not entirely level (like as shown in FIGS. 1 and 3) a user turns the extended knob 30 of the leveling jack 1 so that the front end 6 of the leveling jack 1 (with the extended bar 80) is raised upward and contacts the bottom 11 of the gun sight 10 and therein levels the gun sight 10 by pushing the extend bar 80 of the leveling jack 1 against the bottom 11 of the gun sight 10 in a flush manner.

(13) In one embodiment, a spring (not shown) may be attached to the leveling jack 1. In the resting position, the leveling jack 1 may be in the generally relaxed position of FIG. 1. When a user hits a trigger, the spring is activated and forces the front end 6 of the leveling jack 1 upward so that the extended bar 80 contacts the bottom 11 of the gun sight 10 and levels the gun sight 10. Once the trigger is released, the front 6 of the leveling jack 1 may return to the downward position of FIG. 1.

(14) The internal spring may be biased in the downward position. When a user moves the extended knob 30 upward to level the sight 10, the spring gets stretched. Once the user releases the upward pressure on the extended knob 30 the leveling jack 1 returns to the down (lowered) position of FIG. 1. In an embodiment, the leveling jack 1 may have at least one preset level which allows a user to move the leveling jack 1 to the desired preset level.

(15) Finally, in one embodiment, the leveling jack 1 is at least partly magnetic so as to be able to be better secured to the gun or rifle 100. Further, in one embodiment, the extended bar 80 is magnetic and attracted to the bottom 11 of the sight 10 so that the force of the extended bar 80 is constantly attracted and constantly leveling the sight 10 when the leveling jack 1 is in the upward position.

(16) Although embodiments of the invention are shown and described therein, it should be understood that various changes and modifications to the presently preferred embodiments will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the invention and without diminishing its attendant advantages.
