Description
- This Non-Provisional Application claims benefit to U.S. Provisional Application Ser. No. 60/703,949 filed Jul. 29, 2005, which is incorporated by reference in its entirety herein.
- The present invention is directed to firearms and more specifically to a detachable carrying handle for use with firearms, including without limitation for use with semi-automatic and automatic firearms.
- Semi-automatic and automatic firearms are known, having been used extensively for recreational and military purposes. While such firearms have numerous objectives, several important objectives include reliability, range and accuracy.
- To provide increased accuracy, firearms can be equipped with a
front sight system 10 and arear sight system 50, as illustrated by the partial depiction of afirearm 5 inFIG. 1 . By aligning front and rear sights, the direction of a fired bullet can be more accurately predicted. As is known, however, a particular setting of the sighting system is only accurate for a particular range of distances because a bullet drops as it travels forward due to the effects of gravity. Therefore, mechanical sighting systems are basically a prediction of the expected bullet trajectory and match the actual bullet trajectory for a certain range of distances. When the sights are non-adjustable, they must be aimed further and further above the intended target as the distance to the target increases, making the firearm more difficult to accurately aim. This is especially problematic when attempt to aim at distant targets if the sights accurately predict the bullets trajectory at shorter distances, for a user may have to aim far enough above the target so as to make it difficult to determine if the sights are actually aligned with the target. To compensate for this, certain designs have allowed for a limited amount of adjustment in the position of the sights. For example, by raising or lowering the rear sight, the distance at which the predicted bullet trajectory matches the actual bullet trajectory increases or decreases, respectfully. Conversely, by raising or lowering the front sight, the distance that the predicted trajectory will match the actual bullet trajectory decreases or increases, respectfully. - While sights can be mounted as stand alone units, conventional automatic or semiautomatic firearms can be configured to include a carrying handle that includes a rear sight. The carrying handle allows the firearm to be readily carried with one hand while the rear sight may be used, along with the front sight, to align the firearm's barrel with the target, as discussed above. In certain configurations, the rear sight that was mounted to the carrying handle could provide a limited amount of adjustment. Therefore, a user may adjust the position of the rear sight (i.e., “sight in” the firearm) so that a bullet fired from the firearm hits the target at the desired location (i.e., the sight's predicted trajectory matches the bullet's actual trajectory). For example, it is known that a rear sight mounted to a carrying handle could be adjusted, in combination with a front sight adjustment, to allow the firearm to hit a target accurately from 50 yards (or less) up to 600 yards. However, current combination handle and sight systems do not allow, for example, a user to accurately aim at a target that is 200 yards away and, with only adjustments to the rear sight, still be able to accurately aim the firearm at a target that is a distance of 600 yards away. This is because the range of vertical travel that is allowed for the rear sight is insufficient to predict a bullet trajectory at shorter as well as longer distances. Therefore, the theoretical effective range of the firearm can exceed the sighting system's ability to predict the bullet's trajectory for a given setting of the front sight.
- Consequently, there exists a need in the art for a carrying handle for a firearm that includes a rear sight that allows the predicted trajectory of a fired bullet to match the actual trajectory of a fired bullet over a greater range. The present invention addresses these and other known drawbacks with existing firearms and the limited range provided when using a rear sight mounted to the carrying handle.
- The present invention therefore can provide a solution to the problems of limited range of known carrying handle/rear sight combinations. An embodiment of the invention includes a detachable carrying handle for a firearm, such as a semi-automatic and automatic firearm, having an attached rear sight that allows the predicted trajectory to match the actual trajectory over an increased range of distances.
- More specifically, in an exemplary embodiment a firearm that includes a detachable carrying handle that further comprises a carrying handle body that defines a window to receive a rear sight base of a rear sight. The carrying handle body further includes a pin opening positioned below the window that is configured to mount the rear sight base of the rear sight to the carrying handle body through the use of a pin. The rear sight base further defines a sight opening and a threaded end that is configured to mate with a threaded opening of an elevation knob positioned in the window. The elevation knob may be used to adjust the height of the rear sight. The threaded end of the rear sight base further includes at least one elongated slot that is configured to receive the pin that is used to secure the rear sight base to the carrying handle body.
- Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings in which like numerals are used to designate like features.

FIG. 5 b is a top view of an embodiment of a carrying handle body -
FIG. 5 c is an isometric view of an embodiment of a carrying handle body. -
FIGS. 6 a-6 b are front and side views, respectively, of an embodiment of a rear sight base. -
FIGS. 7 a-7 d are various views of an embodiment of an elevation knob. - The present invention may be embodied in many forms as illustrated by the Figures. As can be appreciated, the depicted embodiments allow for a greater range of adjustment if just a position of the rear sight is modified. For example, if a firearm is sighted in at 200 yards with a rear sight in the full down position, by rotating the elevation knob alone a user can adjust the aim of the firearm so that the predicted trajectory of the sight system matches the actual trajectory of a bullet fired at a target that is 600 yards away.
- As can be appreciated, an embodiment having this range of adjustment has certain benefits. For example, having to adjust the front sight in order to obtain the desired range of accuracy forces the user to cease to hold the firearm in a ready position, possibly causing the user to become ineffective for a period of time while the adjustments is made. Furthermore, the front sight typically requires a special tool to adjust and the need to carry an additional tool makes it less likely that a user will have the desired tool when the adjustment is needed, not to mention the undesirable nature of doing such an adjustment during a pressure situation. Therefore, the ability to adjust the predicted trajectory so that it matches the actual trajectory of the bullet over a range of 400 or more yards by only adjusting the position of the rear sight can be helpful.
- To provide this desirable adjustability in predictive range of the sighting system, locating the front and rear sight closer to the centerline of barrel has the effect of making the same adjustment in the vertical position of the rear site provide more of an effect on the orientation of the firearm for a given range of motion. Thus, all other things being equal, a first configuration of a rear sight and a front sight that are both positioned farther away for the centerline of the firearm barrel will be able to provide less of a range of a predictive bullet trajectory matching the actual bullet trajectory when compared to a second rear sight and front sight that are positioned closer to a centerline of the firearm barrel.
- It should be noted that firearms have an inherent accuracy and, therefore, when discussing accuracy it is assumed that the firearm will only be as accurate as the components and tolerances allow. For example, depending on the configuration of the firearm and a cartridge, the normal tolerance may be plus or minus about one inch at 100 yards. It is further noted that the tolerance will increase as the distances to the target increases.

FIG. 2 shows an embodiment of an assembledcarrying handle system 200 that may be mounted to a known firearm. Thecarrying handle system 200 includes, among other features, acarrying handle body 210 that includes ahandle portion 212 and asight portion 215 that support arear sight system 250. Thehandle portion 212 may include twofasteners 220 that are mounted in twohandle body apertures 221 and are configured to secure thecarrying handle system 200 to a firearm. Thesight portion 215 includes anupper member 216 and alower member 217 that define awindow 265 that is sized and shaped to receive anelevation knob 270 that, in operation, adjusts the position of the rear sight with respect to asight portion 215. Positioned below thewindow 265 is apin opening 280 for receiving apin 281 used to secure therear sight system 250 to thesight portion 215 of thecarrying handle body 210. - Looking at
FIGS. 3 and 4 , arear aiming point 290 is supported by asight base 251. The position of therear aiming feature 290 is supported by amember 276 and therear aiming feature 290 can be adjusted left and right by rotating wind adjustment knob 275 (to compensate for the wind) and up or down by the elevation knob 270 (to compensate for the distance to the target).Member 276 may be mounted, in turn, to a pair of sight base windage screw holes 253. Looking atFIGS. 7 a-7 d, theelevation knob 270 includes a threadedopening 272 that is configured to engage a threadedend 255 of the rear sight system 250 (FIGS. 6 a-6 b). Therefore, by rotating theelevation knob 270, the height of therear aiming point 290 can be adjusted and the firearm can be sighted in for the desired range because the adjustment of the rear sight affects the orientation of the firearm with respect to the target, and therefore modifies the trajectory of the bullet relative to the sighting system. In an embodiment, holes 273 and 274 may be configured to engage a detent, not shown, that holds the elevation knob in the desired location until the user rotates it. In an embodiment, theholes 273 can be about 30 degrees apart and theholes 274 can be about 15 degrees apart, although other ranges can also be used, depending on the configuration of the handle and rear sight. - The dimensions of the
sight portion 215, which includes theupper member 216 and thelower member 217, as well as the size and location of thewindow 265, is limited by the size of the carryinghandle body 210. Applicants have found, however, that apin opening 280 in thelower member 217 with a diameter of about 0.079 inches allows the use of an smaller sized pin so that elevation in the full up position can be increased by 0.029 inches. In an embodiment, thepin opening 280 may be positioned approximately 0.029 inches from abottom surface 265 a of the window 265 (e.g. the center of thepin opening 280 may be located approximately 0.0685 inches from thebottom surface 265 a). - The
rear sight base 251 defines asight opening 252 and the threadedend 255 is sized to mate with a threadedopening 272 of anelevation knob 270 that will be positioned in thewindow 265 and used to adjust the height of the rear sight. To install the threadedend 255, theelevation knob 270 is placed in the window 265 (which may be 0.385 inches tall) and the threadedend 255 is inserted into thesight portion aperture 218. Once the threadedend 255 engages the threadedopening 272 of theelevation knob 270, theelevation knob 270 may be rotated so as to allow the threadedend 255 to be installed. To provide a desired degree of adjustability per 15 degree rotation of theelevation knob 270, the threads of the threadedend 255 and the threadedopening 272 can be configured as 1/2-28 UNEF-2A MOD and 1/2-28 UNEF-2B MOD. Such a thread configuration allows for a fifteen degree turn to provide the desired change in angle of the sights. The threadedend 255 includes an elongated slot 256 (which may be a pair of elongated slots 256) that is sized and shaped to receive a pin 281 (FIG. 4 ) that is inserted in thepin opening 280 and is used to secure therear sight base 251 to thesight portion 215 of the carryinghandle body 210. Theelongated slot 265, which includes a top 265 a and a bottom 265 b, defines a slot length of approximately 0.260 inches where the top 265 a of the slot 260 may be approximately 0.749 inches fromcenters 253 a of sight base windage screw holes 253. The length of theslots 256 combined with the location and size of the pin opening 280 (and the pin 281) as well as the distance between thecenter 253 a of the sight base windage screw holes 253 and acenter 221 a of the twohandle body apertures 221 has shown to result in an improved firearm. In particular, the combination allows the handle/rear sight system to accurately predict the trajectory of a fired bullet at a greater range of distances than was previously possible when only the rear sight was adjusted. - For example, in an embodiment the distance between a
center 253 a of the sight base windage screw holes 253 and a line defined bycenters 221 a of the twohandle body apertures 221 is about 0.959 inches when then rear sight in the full down position. The firearm can then be sighted in for 200 yards by adjusting the front sight while the rear sight is in the full down position. If the rear sight can translate a total of about 0.260 inches, then the predicted trajectory of a fired bullet can be set to accurately match the actual trajectory of a bullet fired from the firearm over distances ranging from about 200 to about 600 yards by translating only the rear sight through the range of 0.260 inches. - Consequently, with the principles and teachings of the present invention, as described, the known problems of limited range of existing firearms using a rear sight mounted to the carrying handle are overcome.
- Variations and modifications of the foregoing are within the scope of the present invention. It should be understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the present invention. The embodiments described herein explain the best modes known for practicing the invention and will enable others skilled in the art to utilize the invention. The claims are to be construed to include alternative embodiments to the extent permitted by the prior art.
- Various features of the invention are set forth in the following claims.
