Abstract
An adjustable sling system provides a quick release fitting which enables a sling system to transition from a close to the body quick fire position to an away from the body aiming position. The adjustable sling system incorporates a first end having a first attachment fitting carried closer to the forward grip of a rifle having a first portion of the first end attached to an extended rubber core web surrounded section. A release clip has a first end supported by a tension ring which is supported along a length of webbing extending from the first portion, and includes a riveted connection to the web strap and reinforcement plate as it extends from the first end. The slope in the direction of capture is calculated with respect to the force of the spring action to insure that the close body position is maintained absent a deliberate forward aiming motion. A second adjustable sling system for use with military full back pack or load bearing equipment such as a load bearing vest enables a slide fitting on a rifle sling to be used with a “Y” shaped support which connects to a backpack. Rifle attached fittings are disclosed which permit rifles to be supported in the vertical position with either of the first or second adjustable sling systems.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a tactical sling system to assist and enable law enforcement and military personnel to better and more efficiently support and usefully manipulate their sling mounted weapons, and more particularly to systems which enable close body carriage in high alert situations and converting to a distanced body carriage to enable a sight aimed position.




Conventional weapons sling systems have several shortcomings which denigrate their complete utilization in tactical situations. The first and most obvious is seen with respect to the vast majority of slings which are used for the two main purposes of carrying a rifle or other long weapon from a shouldered position, and the use of the sling for wrapping partially about the extended arm of the shooter to steady the weapon for sniping or distance aiming. The carriage of the weapon near the body in its upright orientation simply is not easily attainable with most sling systems because the attachment points for a sling on a conventional rifle or other long weapon is from fittings on the bottom of the rear stock and extending from a position at the bottom of the weapon near the front grip.




Further, most sling systems do not enable the rifle to be carried close to the body with a quick adjust to a second carriage position where the rifle may be brought forward for action. Most straps require a fumbling adjustment to go from one position to the other. With these limitations, the weapon may be carried close to the body and only fired on short notice in a lowered position. Alternatively, a strap can be adjusted to an extended position, but the rifle will receive no substantial close body support except by the user supporting it completely by the use of the arms. The fatigue factor from supporting the rifle completely with the arms diminishes the reaction time and accuracy of the user.




Most tactical team members carry, in addition to a rifle, supplies, communication equipment, ammunition, body armor, and other utility equipment. Managing the rifle, in addition to the other equipment, makes the need for a tactical sling system even more acute.




What is needed is a sling system which enables a rifle to be carried in an upright, ready for firing orientation, and provides a quick, virtually instant transition between a close to the body fire-from-a-lowered-position orientation to an extended aiming fire orientation. The needed sling system should be as silent as possible, avoiding self generated sounds as well as making sounds against the rifle or other equipment. The sling system should provide for stable support of the rifle in all of the carry positions and release only by either the natural aiming action, or by a manual release. The needed sling should be adjustable to enable a user to adjust for a variety of both close to the body and away from the body positions. The needed sling should also have the ability to permit backpack carry of the rifle.




SUMMARY OF THE INVENTION




To meet the above described need, an adjustable sling system provides a quick release fitting which enables the sling system to transition from a close to the body quick fire position to an away from the body aiming position. The adjustable sling system incorporates a first end having a first attachment fitting carried closer to the forward grip of a rifle having a first portion of the first end attached to an extended rubber core web surrounded section. A release clip has a first end supported by a tension ring which is supported along a length of webbing extending from the first portion, and includes a riveted connection to the web strap and reinforcement plate as it extends from the first end. The release clip has an overall “U” shape, and where one side of the “U” shape is indented to apply force to the other side to provide one factor in keeping a buckle fitting within the release clip when a rifle is to be carried at the side in quick shoot position. The angular approach to the force contact area is more gently sloped in the direction of entry to facilitate a re-positioning into the close body position. The slope in the direction of capture is calculated with respect to the force of the spring action to insure that the close body position is maintained absent a deliberate forward aiming motion. In addition the buckle fitting includes a first aperture which enables it to slide on the web strap away from the first end, and a second aperture through which the release clip operates and which secures a post on the buckle fitting between the first and second apertures, and within the release clip. The buckle fitting is curved to provide increased holding force when the rifle is carried in the close body position and to provide an easier release force when the rifle is raised to the aiming position.




The web strap extends away from the first end, through a shoulder adjust fitting, then through a strap aperture of the buckle and then to a termination at the shoulder adjust fitting at a second end. The second end typically terminated in a loop about the shoulder adjust fitting. A sliding fitting preferably includes a tension ring which slides along the web strap nearer the first end of the an adjustable sling system and provides a second attachment fitting to attach to the rifle nearer its stock end. Permissible terminations for both the first and second attachment fittings may include hooks, snap hooks, or buckle and web adjustable attachment fittings.




A second adjustable sling system for use with military full back packs is disclosed and which enables a sliding fitting on a rifle sling to be used with a “Y” shaped support which connects to a backpack or load bearing equipment. This second adjustable sling system enables a soldier to off load some of the effort in supporting his rifle on the sling system while enabling a wide range of support orientations of the rifle to be achieved. The rifle may be left to rest in a general vertical, downwardly oriented position to free the soldier's arms when the rifle is not being utilized.




Rifle attached fittings are disclosed which permit rifles to be supported in the vertical position with either of the first or second adjustable sling systems.

DETAILED DESCRIPTION




A detailed description of the embodiments of the invention are best begun with reference to

FIG. 1. A

wearer


31


carries a rifle


33


utilizing a first embodiment of the sling system


35


. The system


35


is utilizable with any relatively longer weapon such as a rifle, shotgun, machine gun, carbine, or other weapon. The description is made with respect to a rifle, but the rifle embodies all of the aforementioned weapons and more. The sling system


35


is attached near the forward end of rifle


33


at a bayonet fitting


37


and at point near the stock of the rifle


33


by a ring fitting


39


. The fittings


37


and


39


were chosen for this particular rifle, the M-16, due to the availability of structure supporting the fittings


37


and


39


and it is understood that other rifles will have other structures for supporting different types of fittings which may be utilizable with the sling system


35


of the invention. Generally, the only objective of such other fittings is that they permit the rifle to be carried in a generally upright position as seen in FIG.


1


.




The sling system


35


is seen extending from a point near the ring fitting


39


up along the right side of the wearer


31


, across the wearer's back and left shoulder, and thence across the wearer


31


's chest to terminate at a curved buckle


41


engaged by a clip


43


. The buckle


41


, when not engaged by clip


43


is set to slide freely along a length of web strap


45


extending between the ring fitting


39


and the bayonet fitting


37


.




Note the curvature of the buckle


41


and the close body position of the rifle


33


and in which the rifle is carried in a relatively forward position. As the rifle


33


is brought farther down, the buckle fitting


41


achieves a more angled position against a fitting adjacent the length of web strap


45


extending between the ring fitting


39


and the bayonet fitting


37


. In this position, the buckle fitting


41


is almost locked in place and will not leave the clip


43


. If the rifle


33


is brought more forward, the buckle fitting


41


will assume an orientation more nearly parallel to the length of web strap


45


, and the disengagement of the buckle fitting


41


will be in an optimum position to be disengaged from the clip


43


upon application of a tension force from the user's left shoulder pulling rearward on the buckle fitting


41


.




An adjustment fitting


49


is provided to enable a loosening or tightening of the sling system


35


regardless of whether the sling system


35


is carried in a position close to the body or in a position to permit firing. The adjustment fitting


49


is preferably a three parallel post fitting having a pair of adjacent openings but wherein the termination of the strap of the sling system


35


loops around one outside post and where the slidable length of strap enters one opening, extends over a middle post and exits downwardly through the second opening and underneath the termination about the adjacent outside post. The action which results is the ability to lengthen the sling system


35


by simply pulling downwardly on the strap which is outermost with respect to the user


31


. Tightening the general fit of the sling system


35


involves a manual lifting of the adjustment fitting


49


while pulling down on the strap which is innermost with respect to the user


31


.




Referring to

FIG. 2

, a position of the sling system


35


in which the buckle fitting


41


is released from the clip


43


has enabled the buckle fitting


41


to slide rearwardly toward the ring fitting


39


. In this condition, the buckle fitting


41


can move rearwardly to the ring fitting


39


. However, the ring fitting


39


is also slidably connected to the length of web strap


45


. Although the rearward movement of the buckle fitting


41


is limited by a second fitting (not yet seen) near the ring fitting


39


, the length of web strap


45


can continue to move through both the second fitting (not yet seen) and the buckle fitting


41


to enable a further freeing of the rifle


33


at the expense of a tightening of the portion of the sling system


35


extending around the wearer.




Referring to

FIG. 3

, a closeup of the buckle fitting


41


and retaining clip


43


is seen. Beginning with the rifle


33


, a bayonet fitting


37


includes a ring structure


51


onto which a snap fitting


53


is engaged. The snap fitting


53


is attached to a hugging strap (not shown) which is closely sewn to a folded and sewn first end


55


of the sling system


35


. The strap material at the first end


55


is folded around a block of rubber


57


to provide stiffness and noise silencing. In addition, a stiff length of thin material


59


is partially secured by rivets


60


, and is also partially inserted into a fold


61


formed by the strap material as it surroundably encloses the block of rubber


57


. The combination of the thickness of the strapping extending away from the block of rubber


57


toward the main extent of the sling system


35


and the stiff length of thin material


59


is thin enough to accommodate an opening


63


of the curved buckle fitting


41


. A second opening


63


is a main opening and accommodates the clip


43


passing through the opening


63


, and over a post


65


. An upper opening


67


is engaged by a looping strap of the sling system


35


and includes an innermost strap section


69


and an outermost strap section


71


, taken with respect to the body of the user of FIG.


1


.




The retaining clip


43


includes a gently angled portion


75


terminating in a cylindrically curled end


77


, as well as a main internal space


79


bounded by a more abruptly angled portion


81


. The more abruptly angled portion


81


assists in retaining the post


65


once captured within the retaining clip


43


, while the gently angled portion


75


assists in manually capturing the post


65


within the retaining clip


43


.

FIG. 3

shows the wearer


31


manually re-setting the curved buckle fitting


41


to be held within the retaining clip


43


.




Note the curvature of the curved buckle fitting


41


. In a high angle position with respect to the captured length of web strap


45


and stiff length of thin material


59


, an outer edge post


85


and post


65


have an angular relationship which is somewhat restrictive of movement of the buckle fitting


41


along the length of web strap


45


. This restrictive pinching, combined with the fact that the pulling force is perpendicular with respect to the length of web strap


45


and stiff length of thin material


59


, gives the sling system


35


high holding force for the rifle


33


in the close to body position. As the curved buckle fitting


41


begins to recline with respect to the length of web strap


45


and stiff length of thin material


59


, the opening


63


begins to loosen about this combination of materials and becomes more freely slidable. In addition, when the innermost and outermost strap sections


69


and


71


cause the curved buckle fitting


41


to recline and to exert a force on the curved buckle fitting


41


more parallel to the length of web strap


45


and stiff length of thin material


59


, a force begins to bear directly upon the abruptly angled portion


81


. This force causes the release of the curved buckle fitting


41


from the retaining clip


43


. Because the outer edge post


85


always bears on the combination of the length of web strap


45


and stiff length of thin material


59


, the force from the curved buckle fitting


41


never upwardly bears on the upper member of the retaining clip


43


to cause it to open from such perpendicular force. As a result, the retaining clip


43


is always protected from strap forces, will never become bent open due to strap forces, and will operate against the length of web strap


45


and stiff length of thin material


59


time after time with only the lateral pushing force of the post


65


, in a direction generally parallel to the length of web strap


45


and stiff length of thin material


59


, as the operating force.




The length of web strap


45


surrounding the block of rubber


57


helps to limit the movement of the snap fitting


53


about a pivotal axis parallel to the end of rubber block


57


and thus helps to suppress undue rattling at the end of the sling system


35


at the forward end of the rifle


33


. As will be seen, the innermost strap section


69


and outermost strap section


71


looping through the curved buckle fitting


41


provide a mechanical advantage to the adjustment fitting


49


of FIG.


1


and half the pulling force on the adjustment fitting


49


resulting from any downward pressure on the curved buckle fitting


41


. This enables the adjustment fitting


41


to be less loosely engaged by the innermost strap section


69


and enables the adjustment fitting


41


to be more easily manipulated by the wearer


31


.




Further back along the length of web strap


45


is a second rifle fitting as a slide fitting assembly


91


. Slide fitting assembly


91


includes a slide ring


93


secured by a short sewn stiffened length of strapping


95


formed into a folded “Double U” shape and capturing a length of adjustment webbing


97


in its middle. Adjustment webbing


97


extends through a buckle


99


, around the ring fitting


39


and then back through the buckle


99


. The slide fitting assembly


91


beyond the slide ring


93


represents an alternative example of attachment structure which can be used to attach to structure depending from a rifle. A snap fitting


53


could be used in conjunction with slide fitting assembly


91


, and the adjustment webbing


97


and buckle


99


could be used in conjunction with the folded and sewn first end


55


of the sling system


35


. Other attachment structure can also be used.




Referring to

FIG. 4

, a plan closeup view of a two sided version of the one sided version of the bayonet fitting


37


seen in

FIGS. 1

,


2


, &


3


is seen as a fitting


101


. Instead of a single ring structure


51


, a set of double, left and right side ring structures


103


are seen. The view of

FIG. 4

is a top view, looking down onto the surface which would face the underside of the rifle. A front fork fitting


105


is used to hold the front portion of the fitting


101


in place, while a bolt


107


and lock nut


109


extends through the rear section of the fitting


101


to hold it in place once the front fork fitting


105


is in place. Bolt


107


preferably has a hexagonal drive head


111


.




A lower base plate


113


is for supporting another structure at the bottom of the fitting


101


. The ends


115


of a downwardly directed slot mounting space, which can be used for mounting lasers, lights, and other objects, is seen. It is understood that the fitting


101


accommodates both left handed and right handed wearers


31


but that single ring structures


51


on one sided bayonet fittings


37


can be used. Also seen is the tip end of a pressure set screw


117


which is meant to bear against a bottom surface of the rifle


33


. Since the front fork fitting


105


has an angular mounting process, there will be some tolerance between the fitting


101


and the rifle


33


. Insertion of the bolt


107


at the rear of the bayonet fitting


101


locks it into place, but there may be enough tolerance left for a slight rattle. In addition, where the bayonet fitting is used to support laser sights, etc, the bayonet fitting


101


cannot tolerate either a rattling noise nor any significant instability. The set screw


117


is turned until it rises upwardly and against the rifle


33


, which urges the bayonet fitting


101


downward into a rigid locked configuration.




Referring to

FIG. 5

, the slot


119


can be seen as extending across the fitting


101


. The set screw


117


can be seen in a downward orientation before being threadably turned upward to bear against the rifle


33


. Referring to

FIG. 6

, a bottom view of the bayonet fitting


101


seen in

FIGS. 4 & 5

give a better visual illustration of the components thereof.




Referring to

FIG. 7

, a plan view of a two ring, left and right hand ring fitting


131


is seen which is similar to the ring fitting


39


seen in

FIGS. 1-3

. The fitting rings


131


and


39


provide at least one attachment ring


133


which is configured to protrude from the side of the rifle


33


at a high point relative to the stock of the rifle


33


to enable rifle


33


to be suspended in its normal firing orientation. The use of two attachment rings


133


as seen in

FIG. 7

enables a rifle to be supported from either of the right hand or left hand side.




The fitting


131


has a main aperture


135


which fits over a receiver extension tube support for a stock of a rifle


33


such as an M-16 .223 caliber rifle. The axial thickness of the attachment ring


133


will cause a rifle stock to be displaced rearward by that thickness, which is only about ⅜ of an inch. The opposite faces of the fitting


131


should match the surfaces with which they interfit.

FIG. 7

is a view looking forward onto the fitting


131


and facing the rear surface thereof. A rounded depression interfits with a projection on the stock. The main aperture


135


contains a grooved transition to a greater diameter opening


139


to accommodate the configuration of the rear of the rifle


33


receiver. The smaller diameter is seen surrounding the main aperture


135


.




Referring to

FIG. 8

a side view illustrates the depression


137


which is opposite a projection


141


which fits into an accommodating opening in the rear of the receiver of the rifle


33


. Both the projection


141


and the depression


137


are used to register the fitting


131


so that it will not rotate about its main aperture


135


. Referring to

FIG. 9

, a view of the side of fitting


131


opposite to that shown in

FIG. 7

is seen.




Referring to

FIG. 10

, an illustration of the installation of the fitting


131


is seen. A rifle


33


receiver


151


has a rear surface


153


having a depression


155


. Beyond the depression


155


is a bore supporting a spring


157


to urge a pin


159


outward from the bore supporting the spring


157


. The spring


157


and pin


159


normally urge a stock


161


rearwardly during breakdown to assist in removal and to keep the rifle


33


“tight”. A pair of butt plate screws including an upper screw


163


attach a butt plate


165


to stock


161


and a spacer


167


to a threaded bore


169


in a receiver extension tube


171


. A lower butt plate screw


173


attaches the lower end of the butt plate


165


to the stock


161


.




When the fitting


131


is added, the stock


161


rides just slightly farther back on the receiver extension tube


171


. The upper butt plate screw


163


provided as original equipment is likely not to be able to reach the threaded bore


169


. A new longer upper butt plate screw


163


is provided along with a spacer


175


to compensate for the slight rearward displacement of the stock


161


while providing force distribution for the spacer


167


against internal structures in the stock and rear structures of the receiver extension tube


171


.




Referring to

FIGS. 11 and 12

, installation of the bayonet fitting


101


is illustrated on a rifle


33


having a front grip


181


. Just below the barrel


183


, a split structure


185


contains a pair of side members


187


, only one of which is seen in the side view of FIG.


11


. The front fork fittings


105


of the bayonet fitting


101


are brought upward and forward at an angle to rest upon the side members


187


. The bolt


107


has been removed from a bore


189


of the bayonet fitting so that the bore


189


could be brought into alignment with a pair of apertures of which one aperture


191


is seen on the rifle


33


. Once the apertures


191


are aligned with the bore


189


, the bolt


107


is inserted therethrough and the lock nut


109


is added to the bolt


107


. This is seen in FIG.


12


. Next, the set screw


117


is rotated until it bears on a surface


193


below the barrel


183


to force the front fork fitting


105


down into a stable configuration.




Referring to

FIG. 13

, further details of the sling system


35


are seen. Beginning at the first end


35


, an outer closely sewn loop of material


201


is seen to engage the snap fitting


53


, and a rectangular connector ring


203


. Connector ring


203


engages the retainer clip


43


in its main internal space


79


and provides a force anchor opposing the pulling of the curved buckle fitting


41


from the retaining clip


43


. The space between the innermost strap section


69


and the length of web strap


45


is generally where the wearer


31


's shoulder is located. Stitching


205


is seen joining the end of outermost strap section


71


around an end post of the adjustment fitting


49


. The innermost strap section


69


is seen extending through one opening of the adjustment fitting


49


, over a middle post


207


and back underneath a second side post


209


. Stitching


211


is seen on the sewn stiffened length of strapping


95


.

Referring to

FIG. 16

, the sling system


35


is seen in a backpack configuration achievable by loosening the adjustment fitting


49


and bringing it closer to the curved buckle fitting


41


and splitting the length of the strap about the slide ring


93


to two approximately equal lengths between slide ring


93


and first end


55


at the curved buckle fitting


41


and the snap fitting


53


. When utilizing bayonet fitting


101


and ring fitting


131


, the sling system


35


becomes both a right and a left hand system. All that is needed is reversal of the main sling system


35


over the right shoulder, and re-attachment of the snap fitting


53


and the slid fitting assembly


91


to the rifle


33


.




Referring to

FIG. 17

a second embodiment of a sling system


301


is seen in combination with a backpack, of which back pack or load bearing equipment shoulder straps


303


are seen at the front of the FIG.


17


. The backpack straps


303


may be fitted with connector rings


305


which are generally supported along the back pack or load bearing equipment straps


303


to resist downward movement. The connector rings


305


are preferably each integral with a loop suitable for a chest center connector set


306


having three strap sets numbered


307


,


309


and


311


. Each of the strap sets


307


,


309


and


311


includes a length of strapping


313


and a quick connector


315


. Each of the strap sets


307


,


309


and


311


is attached to a central ring


317


. The strap sets


307


&


309


can be adjusted to center the central ring


317


for the comfort of the user.




The quick connector


315


of the strap set


311


is connected to a connector ring


319


which includes a separate ring portion for connection to the quick connector


315


and a ring portion for slidable attachment to a sling strap


321


which is again shown as connected to the rifle


33


, by way of the rifle's bayonet fittings


37


,


101


and ring fittings


39


,


131


which are the same as was illustrated in the earlier Figures. Since the sling strap


321


has an extent with only some extra length between its points of attachment to the rifle


33


, there is an easy movement of the rifle


33


both forwardly and rearwardly with the sling strap


321


freely moveable through the connector ring


319


. In this configuration, the wearer


31


can turn the rifle


33


to a close to the body position, lift the rifle


33


to aiming position, or assume a number of other positions with the arms and hands. Where the arms and hands are needed for other tasks, the rifle


33


can simply be left suspended as seen in FIG.


17


.




Referring to

FIG. 18

, a plan view of the sling strap


321


illustrates a length of webbing


325


having a quick connector


327


at a first end thereof and secured by a stitch


329


. A length adjusting buckle


331


enables the sling strap


321


to have a significantly long range of adjustment. At a second end of the sling strap


321


a quick connector


333


is engaged by the length of webbing looping through the quick connector and back across the length of the sling strap


321


and ending at adjusting buckle


331


. The extent of the sling strap between adjusting buckle


331


and quick connector


333


may be doubled. Further, a set of sliding limit buckles


341


can be utilized on either side of connector ring


319


to limit the extent of movement of a ring portion


343


and connector ring portion


345


. This enables the wearer


31


to set limits on the movement of the rifle


33


in the forward and rearward direction. The adjustment of the strapping lengths of the strap sets


307


,


309


and


311


can determine the ease of lateral motion of the strap set


311


, as well as the height at which the rifle


33


will be supported. Adjustment of the length of the sling strap


321


determines the level and degree of arc which the rifle


33


will achieve as it is displaced forwardly and rearwardly, as well as the as well as the height at which the rifle


33


will be supported. Adjustment of the sliding limit buckles


341


will determine the degree of forward and rearward motion at slight angular pivot. All of the above adjustments give a wide range of adjustability to enable the sling system


301


to have maximum comfort for a wide variety of wearers


31


, and in a wide variety of circumstances.




Referring to

FIG. 19

an alternative to the quick connector


315


is seen as a spring pull release connector


351


. A connecting pin


353


is operated by a handle


355


to release a pivoting curved member


357


. The spring pull release connector


351


provides a positive lock on the connection with any structure.




Referring to

FIG. 20

, a ring fitting


361


utilizable with an AR-15 rifle is seen. The ring fitting


361


is both left and right handed and typically flatter than the ring fitting


131


. A projection


363


within a main aperture


365


registers the ring fitting


361


. A projection


367


on one side lies opposite a depression


369


on the opposite side (shown in phantom) to further register the ring fitting


361


. Connection apertures


371


extend beyond the stock of the AR-15 and provide a comparable degree of stability and support of the rifle in the quick fire or aiming position as has been seen for rifle


33


.
