The present invention relates to a sling for stabilizing weapons and other hand-held equipment during use and for transporting the same. More specifically, the present invention relates to a sling that couples the weapon or equipment to the bearer's body to effect stabilization of the weapon or equipment.
Slings and straps and the like are commonly used for transporting and stabilizing weapons and other hand-held equipment such as rifles, shotguns, handguns, bows, crossbows, binoculars, telescopes, and still and motion picture cameras. As used herein, the term weapon is intended to include rifles, shotguns, handguns, bows, crossbows and other weapons as well as hand-held equipment such as binoculars, telescopes, cameras and the like.
One problem common to slings designed to facilitate the transportation of weapons is that there is little thought given to whether or how these slings may be used to stabilize the weapon during firing. One example is U.S. Pat. No. 3,098,591 to Lerude. Lerude's harness is adapted for carrying a rifle in a slung position but teaches nothing with regard to the stabilization of the weapon during firing. U.S. Pat. No. 4,613,067 to Gann discloses a carrying sling that permits a weapon to be transported in a variety of positions but discloses no manner in which the carrying sling may be used to stabilize the gun during firing.
Other slings attempt to navigate the middle ground between ease of transportation and stabilization of the weapon for firing. Examples of such patents include U.S. Pat. No. 4,331,271 to Anderson and U.S. Pat. No. 6,260,748 to Lindsey. Anderson discloses a sling for shoulder guns in which a shoulder gun is supported in a slung position from a belt to which is attached a strap. Pains are taken to insure that the shoulder gun will maintain its slung position during transport. However, for stabilization, Anderson relies on the well-known technique of wrapping the sling strap about the elbow of the arm with which the bearer of the weapon grasps the forearm of the stock. In this way, the bearer of the weapon is able to achieve a more secure connection between his or her arm and the weapon. However, this method of stabilizing a weapon for firing relies on the stability of the bearer's arms, an inherently unstable member of the human body. Accordingly, the Anderson sling is not capable of providing much in the way of stabilization for a weapon being fired.
The Lindsey sling is adapted for supporting a weapon across the front of the bearer's chest. A strap may be included between the muzzle end of the weapon and the shoulder of the bearer and by tensioning this strap between the shoulder and the muzzle end of the weapon the weapon may be stabilized to some degree. Not only is Lindsey's sling relatively limited insofar as it offers only two carrying positions for the weapon, but it provides no dissipation of the phenomenon of muzzle flip as the anchoring point for the stabilizing strap is positioned above the muzzle end of the weapon when the weapon is fired.
Other prior art designs have all but abandoned the goal of supporting a weapon for transport in favor of providing a maximum amount of stability for the weapon during firing. U.S. Pat. No. 5,738,256 to Goff et al. discloses an adaptable aiming support that essentially comprises a belt that has a rigid support with a fork at its upper end attached thereto. In use, the fork at the end of the rigid support is placed beneath the forearm or muzzle end of the weapon being fired when the weapon is in its firing position. The Goff et al. aiming support does offer better stability to the weapon during firing but is incapable of use as a traditional sling in that it is not able to support a weapon during transport at all.
U.S. Pat. No. 5,988,466 to Brown is a variation upon the adaptable aiming support of Goff et al. in that the tubular support member upon which a weapon is supported is permanently affixed to the weapon and is constructed and arranged to have a greater degree of rotation, thereby allowing the gun to be moved from a firing position to a carrying position in which the muzzle of the gun points upwardly. However, the weapon remains coupled to the tubular support member and may not be transported apart from the support without first uncoupling the weapon from the support. But in doing so, the weapon will have to be re-coupled to the support for use in the intended manner.
U.S. Pat. No. 6,112,448 to Gray et al. discloses a forearm sling that attempts to improve the stability of a weapon during firing by coupling the weapon to the forearm of the bearer. Again, while coupling a weapon to the arm of a bearer can increase the stability of the weapon during firing to some degree, the arm of a bearer is inherently unstable and cannot adequately stabilize a weapon during firing. What is more, the Gray et al. forearm sling has no way of counteracting the incidence of muzzle flip engendered by the firing of the weapon and does not provide a means for transporting the weapon.
Accordingly, there is a recognized need for a sling for use with weapons of various types and with other types of hand-held equipment that can facilitate the transport of the weapon in a variety of slung positions, in the crook of an arm, or in the hands, that does not involve the need to disassemble the sling. There is also a need for a sling that can couple a weapon to the bearer's body (e.g., proximate, the chest, the back, the hips or other truncal portion of a bearer's body) to sufficiently stabilize the weapon for firing . . . Such a sling must be usable in multiple shooting/use positions.
These and other objectives and advantages of the invention will appear more fully from the following description, made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.
A sling clip is disclosed that has a clamping mechanism capable of releasably securing the strap when the strap is slidably received through an opening in the sling clip. The sling clip also has an attachment mechanism configured to secure the sling clip proximate to a weapon bearer's body. The clamping mechanism is operatively configured to secure the strap within the sling clip when the weapon is in a firing position such that the strap minimizes movement of a muzzle end of the weapon caused by recoil of the weapon upon firing. A weapon sling including the sling clip also is disclosed. The weapon sling also includes a flexible strap having a first end and a second end is disclosed. The first end of the strap is configured to be secured to a weapon near a near a butt end of the weapon. The weapon may be a rifle, shotgun, or handgun as well as hand-held equipment such as a binocular or a camera.
Additional advantages and features of the invention will be set forth in part in the description which follows, and in part, will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention.
An embodiment of the present invention is realized in a sling for a typical rifle or shotgun. The rifle has a barrel mounted in a stock with a butt end arranged to be positioned against the shoulder of a bearer when the rifle is in a firing position and a forearm portion positioned adjacent a muzzle end of the barrel, with the muzzle end of the rifle being supported at the forearm portion of the stock by the bearer when the rifle is in its firing position. The rifle is steadied in its firing position by a sling that comprises a flexible strap that has a first end and a second end. The first end of the strap is rotatively attached to the rifle adjacent its butt end, the second end of the strap being similarly attached to the rifle at the forearm portion of the stock of the rifle adjacent the muzzle end of the barrel of the rifle. Typically, the strap of the sling is attached to the rifle using standard, well-know devices such as a simple D-ring screwed to the stock of the rifle or a hammerhead sling socket. The strap also has an intermediate portion that is coupled proximate to a body portion of the bearer of the rifle (e.g., waist, side, chest, or back).
When the rifle is in its firing position with the butt end of the rifle positioned against the bearer's shoulder, the strap of the sling extends downward to the bearer's waist and from there to the forearm portion of the stock of the rifle, thereby creating a relatively rigid coupling between the waist or torso of the bearer of the rifle. This coupling between the muzzle end of the rifle and the waist of the bearer prevents recoil forces engendered in the rifle as a result of firing the rifle from causing to the muzzle end of the rifle to rise. This rise, called muzzle flip, can negatively affect the aim of the bearer and result in inaccurate and imprecise shooting.
A feature of an embodiment of the sling is that the strap of the sling is also capable of supporting the rifle in a carrying position in which the rifle is positioned on the back of the bearer for transport.
The strap of the rifle sling of the present invention may be coupled to the waist or torso of the bearer of the rifle in many ways. It must be pointed out that in at least one embodiment of the present invention the sling strap 20 is simply passed through the belt 28 or a belt loop 27 of the bearer. Because the butt end of the rifle stock is firmly anchored to the shoulder area of the torso, the fixed length of the strap effectively couples the muzzle end of the rifle to the waist of the bearer so as to prevent or at least reduce muzzle flip.
In another embodiment as shown in
Where desirable, the sling strap may be constrained with respect to the bearer's waist and to the carabiner type structure used to couple the sling strap thereto. A simple way of accomplishing this is to secure a stop to the sling strap so as to control the movement of the sling strap through the carabiner or loop that couples the sling strap to the bearer's waist. The stop creates a relatively rigid connection of predetermined length between the muzzle end of the rifle and the waist of the bearer by limiting the travel of the sling strap through the carabiner or ring coupled to the waist of the bearer. Another, more complex embodiment of the present invention comprises a sling clip that is coupled to the waist of the bearer and which is constructed and arranged to releasably grip the strap of the sling when the rifle is in its firing position. Once the rifle is in its firing position, the sling clip grasps the strap and securely couples the muzzle end of the rifle to the waist of the bearer to prevent or limit muzzle flip.
In general, the sling strap should be substantially non-elastic or have an elasticity that is relatively low. Good examples of suitable materials from which the sling strap may be fashioned include webbing of nylon and other synthetic materials such as Kevlar, polyvinyl chloride, and the like and natural materials such as leather.
A feature of the preferred embodiment sling is that the flexible strap and the sling clip permit the bearer of the rifle to carry the rifle in the port arms position, cradled in the crook of the bearer's right or left arm, cantilevered over the bearer's right or left forearm with the stock of the rifle being wedged under the bearer's respective arm, to be slung over the shoulder of the bearer, to be slung across the bearer's back, and to be carried in the hand of the bearer with the bearer's arm extended, respectively. Similarly, the rifle may be fired from a group of firing positions consisting of a prone position, a sitting position, a squatting position, an offhand position, a standing position, a kneeling position, and a rest position in which the rifle is supported, at least in part, by an object that is not the bearer of the rifle. The rifle may be freely moved between the transport or carrying positions and the firing position with ease and without requiring the sling strap to be uncoupled from the hips of the bearer.
The sling 10 essentially comprises a strap 20 that is secured at a first end 22 to the butt end 14 of the rifle 12 and at a second end 24 to the muzzle end 16 of the rifle 12. See
The strap 20, along with any adjustment mechanisms and the mechanisms whereby the strap ends 22, 24 are secured to the rifle 12 are preferably inelastic . . . While the strap 20 must be flexible in order to facilitate firing and transportation of the rifle 12, it is important that once configured, the strap 20 maintains substantially the same length at all times. While it is appreciated that the preferred materials from which the strap are made, namely leather and nylon webbing, do incorporate some degree of flexibility, this inherent flexibility is within the requirements of the present invention. At the very least, it is important to minimize the degree of flexibility present within the strap 20 and therefore it may be preferable to utilize a substantially inelastic material such as Kevlar™, carbon fiber composites, or the like.
The portion 25 of the strap 20 intermediate the ends 22, 24 is passed through a sling clip 26. The sling clip is in turn coupled to the waist or truncal portions of the bearer B. In the simplest embodiment of the present invention as illustrated in
The secure placement of the butt end 14 of the rifle 12 into the shoulder of the bearer B, along with the secure coupling of the intermediate portion 25 of the strap 20 to the waist of the bearer B effectively couples the muzzle end 16 of the rifle 12 to the waist and truncal portions of the bearer B. The application of a light to moderate upward force against the forearm 13c of the rifle by the forward hand of the bearer B, indicated by arrow F, serves to complete the coupling of the muzzle 16 of the rifle 12 to the truncal portions of the bearer b by creating of a relatively rigid structural member having a triangular shape with apexes at the first and second ends 22, 24 of the strap 20 and at the intermediate portion 25 of the strap 20 where it passes through the sling clip 26.
When the rifle 12 is fired, the recoil engendered by the firing tends to create a moment indicated by arrow M that is commonly referred to as muzzle flip. In rifles, shotguns, or other weapons constructed and arranged for a high rate of fire such as with semi-automatic and fully automatic weapons, the additive effect of multiple applications of the moment M can result in severe accuracy problems in that the muzzle end 16 of the rifle 12 will be jerked out of alignment with an intended target (not shown). The sling 10 of the present invention counteracts the moment M by applying a counteracting corrective force indicated by arrow C to the muzzle end 16 of the rifle 12 through the second end 24 of the strap 20. Because the rifle 12, the truncal portion of the bearer's body between the shoulder and the waist, and the strap 20 maintain essentially the same dimensions at all times during the firing of the rifle 12, the moment M engendered by the recoil in the rifle 12 will be counteracted by a tension in the strap 20 indicated by arrow C. Note that the rifle 12 may be fired in many different positions while using the sling 10 of the present invention. By way of example, and without limiting the application of the present invention in any way, a rifle 12 incorporating the present invention may be fired from an offhand standing position as seen in
Because the intermediate portion 25 of the strap 20 may freely pass through the sling clip 26 illustrated in

The fulcrum arms 44 are rotatively pinned at their opposing ends to an intermediate portion of the lever arm 40 by pins 48. When the lever arm 40 is moved from its open position to its closed position as shown in phantom in
