Kellis "T" scope mounting system
A firearm scope mounting system where recesses and protrusions in the scope ring precisely mate with like recesses and protrusions in the telescopic sight tube itself to prevent the scope from moving fore and aft as well as rotationally under recoil or other forces. Additionally, these mating surfaces can be designed in such a way that the crosshairs of the scope are perfectly aligned horizontally and vertically when the scope is installed in the rings. The method of attaching the scope rings to the base and the base to the firearm is not the subject of this patent claim.
1. Field of the Invention
The present invention relates generally to accessories for firearms, and more specifically to a recoil-proof mounting system for firearm telescopes.
2. Description of Related Art
Optical devices have been attached to firearms for over 100 years. These are familiarly known as telescopes, or simply scopes. The scope permits the shooter to more easily see a distant target and more precisely aim at the target than is normally possible with non-optical sights. In order to function properly together, the firearm and the scope must be attached in a manner that ensures that the scope and firearm are in the same position relative to each other for each shot fired. If the scope shifts relative to the firearm, the firearm will not be capable of striking the same point of impact.
Scope mounts are subject to the full recoil and impulse force from the firearm when it is fired. This abuse tests even the strongest scope mounts. As technology in steel and gunpowder advance, firearms become more and more powerful. Thus, the stresses on the scope mounting system keep increasing. Scopes are usually mounted to a firearm via two mechanisms. The first is one or more mounting bases that attach to a firearm and provide an attachment point for the other mechanism. The second mechanism includes one or more scope rings. The scope rings encircle a smooth, tubular scope body and attach to the mounting base(s). Scope bodies are universally constructed of smooth tubes. Scope rings must rely on a high amount of surface area and friction to hold onto a scope without damaging it. Too often, the surface area and friction are not enough to hold a scope in place. Many solutions have been sought, including adding more rings to existing systems, but some of today's lighter, more powerful firearms are easily capable of overpowering such scope mounting systems.
BRIEF SUMMARY OF THE INVENTIONThis device involves two improvements over current telescopic firearm scope mounting technology. This system prevents movement in all directions, fore/aft and rotationally (left/right) hence the name “T System.” I conceived of the idea when a relative mentioned that his scope had slipped and he was going to have to re-mount and re-zero his scope before his next hunt.
The Kellis “T” Scope Mounting System of scope mounting has advantages over not just the current, smooth ring, smooth scope body but other designs as well. It retains the advantage of flexibility in positioning the scope fore and aft for optimum eye relief and also the ability to use rings of various heights to optimize clearance between the scope and the firearm receiver. Other methods using a rigid mount built into the bottom of the scope body tend to be less flexible in these two regards. This system retains the more traditional appearance as well.
Additionally, this system positively locates the scope's crosshairs in perfect horizontal and vertical alignment. This is an advantage over the old trial and error method of crosshair alignment where the installer had to position the crosshairs, and then tighten the rings. Often, the scope would slip rotationally while tightening the screws, then one would have to start over and repeat until the crosshairs were in perfect alignment.
This device involves two improvements over current telescopic firearm scope mounting technology. This system prevents movement in all directions, fore/aft and rotationally (left/right) hence the name “T System.”
The first improvement prevents a scope from slipping fore/aft and rotationally (left and right) under recoil. The second improvement precisely aligns the scope crosshairs vertically and horizontally. This eliminates the trial and error of mounting a scope, with the frequent loosening and re-tightening of the scope rings until the crosshairs are perfectly horizontal and vertical. This device permits the user to simply assemble the device with the firearm and scope, check it once, and then forget about it. It will not move.
The mating of the scope 10 to the ring 14 locks the scope 10 in place once the rings 14, 18 are tightened. This feature prevents the scope 10 from slipping fore and aft under recoil even if the scope ring screws should loosen with time and use. The height, width and shape of the grooves or teeth may be variable depending on the materials employed and any commonly accepted manufacturing standards. The length of the scope ring 14 should also be taken into account for the reason of aesthetics (i.e., one would want the scope ring edges to fall between two of the teeth to make for a neat appearance). A greater number of smaller teeth will give more flexibility in positioning the scope 10 for proper eye relief. Shallow grooves or light scoring could be substituted for the larger “teeth” for less expensive scopes and rings.
This method of scope mounting has advantages over not just the current, smooth ring, smooth scope body but other designs as well. It retains the advantage of flexibility in positioning the scope fore and aft for optimum eye relief and also the ability to use rings of various heights to optimize clearance between the scope and the firearm receiver. Other methods using a rigid mount built into the bottom of the scope body tend to be less flexible in these two regards.
With CNC machining methods in use today, this invention is feasible at only minor cost in production time and materials cost. After the teeth 16 are formed on the scope 10 and keyway 20 is cut through the teeth 16, the scope 10 would be placed in a jig that mimics the scope ring 14 in order to precisely bore the holes for the windage and elevation adjustment mechanisms. Alternatively, the rings 14 and scope tube 10 can be forged under pressure around a hardened mandrel to form the teeth or the parts could be investment cast.
The device includes all methods of mounting a scope into a scope ring where protrusions in one part mate into inverse indentations on the other part. This would include a row or rows of protrusions (teeth), notches, grooves, or any other design where the mating surfaces of the scope and ring(s) are non-smooth. The objective is a mechanical lock of the two parts that does not rely solely on friction.
This device includes any and all methods of positive crosshair alignment of the scope via mating of the surfaces of the scope ring to the scope itself.
Claims
1. I claim a system for rigidly attaching a telescope within a scope mounting ring comprising:
- A scope engagement mechanism on the exterior surface of a telescope;
- A ring engagement mechanism on the interior surface of a scope mounting ring, wherein the scope engagement mechanism and the ring engagement mechanism create a mechanical interference fit that prevents scope movement within the scope mounting ring.
2. I claim the system of claim 1, wherein the engagement mechanism comprises:
- At least one raised ring around the telescope; and
- At least one groove within the interior surface of the scope mounting ring, wherein the raised ring and the groove fit together to prevent longitudinal movement of the telescope within the mounting ring.
3. I claim the system of claim 2, wherein the engagement mechanism further comprises:
- A keyway through at least one raised ring around the telescope; and
- A key protruding from the interior wall of the scope ring to engage the keyway and prevent rotational movement of the telescope within the scope mounting ring.
