Cross Reference to Related Applications

This application claims priority from U.S. provisional application No.62/895,378 entitled "Firearm Sling" filed on 3.9.2019 and U.S. patent application No.16/731,932 entitled "Firearm Sling" filed on 31.12.2019, both of which are incorporated herein by reference in their entirety.

Technical Field

The present disclosure relates to firearms and luggage accessories, and more particularly to lightweight, multi-functional straps and harnesses.

Background

Carrying straps or slings have long been used to carry firearms and various items of luggage. Advantageously, such a strap reduces fatigue and increases the utility of carrying firearms or luggage with the hands by providing support while leaving the wearer's hands free for other tasks. Carrying straps or slings are typically made of leather or webbing (made of cloth or nylon) and are attached to firearms or luggage using various hooks or buckles.

Due to the weight of the carried firearm or luggage, support pads are often provided on the harness to increase the comfort of the wearer. Such support pads provide cushioning to relieve pressure exerted directly on the wearer's shoulders by the straps.

Conventional support pads have several drawbacks. These pads typically comprise multiple layers of material, including an inner cushioning material and an outer fabric layer, and thus can be bulky, aesthetically unpleasing, and add additional weight to the sling. Furthermore, the increased size of the support cushion may create an area for the heat generated by the wearer to accumulate, which may result in undesirable perspiration and discomfort. The outer fabric layer may also be slippery and not stably fit over the shoulder during use.

Accordingly, there is a need for an improved strap system for firearms and luggage that provides comfort, breathability and safety to the wearer without increasing weight or bulk.

Detailed Description

The disclosed subject matter generally relates to improved sling systems. While exemplary embodiments of straps are described in detail below in connection with firearms, the straps described herein may also be used in a wide variety of devices such as luggage, including straps, harnesses, and belts for various pieces of luggage, such as duffel bags, satchels, shoulder bags, field bags, backpacks, front or chest bags, waist and waist bands, binocular televison shells, sports equipment bags, such as golf bags, racquet bags, football bags, softballs, or baseball equipment bags, such as equipment bags or equipment shells for binoculars, rangefinders, cameras, and/or camera lenses, and the like.

As used herein, the term "attachment point" refers to a location for attaching a pad portion of a lanyard system to an item, such as a firearm or luggage to be carried by the lanyard, or to an additional component of the lanyard system. The attachment points may include direct, fixed attachment of the pad portions to the item by, for example, sewing, gluing, stapling, or other fastening methods, or indirect removable or fixed attachment of the pad portions to the item by one or more of straps, buckles, clips, snaps, buttons, D-rings, hangers, other connectors, or combinations thereof.

As used herein, the terms "top," "upper," "bottom," "lower," "front," "rear," and the like refer to a direction or position on the sling system that is associated with a user wearing the sling system upright.

A firearm or luggage strap is provided comprising: a first strap portion and a second strap portion, each of the first strap portion and the second strap portion comprising a coupling mechanism, at least one of the first strap portion or the second strap portion comprising a length adjustment mechanism; a cushion coupled to the first and second strap portions, the cushion comprising a single layer of closed cell foam defining an upper surface and a lower surface, and a plurality of slots extending from the upper surface to the lower surface; and a hem fixed to the periphery of the pad.

One example of an improved lanyard for a firearm or luggage is shown in fig. 1. The lanyard 10 includes a first end 12 and a second end 14, each configured to be coupled to or otherwise affixed to a firearm or luggage by a coupling mechanism (e.g., a removably lockable swivel clip or other similar connector). The sling includes first and second strap portions 16, 18, and a pad portion 20 disposed between the strap portions 16, 18 or coupled to the strap portions 16, 18. In some embodiments, each sling 16 and 18 is sewn directly to the pad portion 20. In some embodiments, for example, one or more of the strap portions 16, 18 may be adjustable to lengthen or shorten the length of the strap to better fit the wearer. For example, buckles 22 are provided to allow length adjustment of the straps 18. As shown in more detail in fig. 5, a short strap portion 32 is sewn to the pad portion 20 to support the buckle 22 allowing the length of the strap 18 to be adjusted. In some embodiments, a strap portion similar to strap 32 is sewn to the pad portion and supports an additional buckle 22 that allows the length of strap 16 to be adjusted.

The relative lengths of the strap portions 16 and 18 depicted in fig. 1 are without limitation. For firearm straps, the strap portion 16 may be relatively short compared to the strap portion 18 because the strap is configured to carry the firearm proximate the user's shoulder. For luggage intended to be carried proximate the chest or hip area of the user, strap portion 16 may be longer than the corresponding strap portion for the firearm hanging strap. In some embodiments, one or both of the strap portions 16 and 18 can be adjusted using the buckle(s) 22 to customize the overall length of the sling to accommodate users of different sizes.

In some embodiments, the cushion portion 20 includes a cushion body 24 made of a single layer of closed cell foam material (e.g., Ethylene Vinyl Acetate (EVA) copolymer). The cushion portion 20 absorbs vibration or impact transmitted from a firearm or luggage. The cushion portions 20 provide a comfortable fit against the wearer's body when the lanyard 100 is worn and a firearm or luggage is carried. The size of the bolster 24 may vary, so long as the bolster 24 is configured to allow a firearm or luggage to be carried on a user and to provide sufficient comfort to the user. For example, the size of the pad may be about 4 to about 10cm in width, about 15 to about 25cm or more in length, and about 0.5 to about 3cm in thickness.

In some embodiments, the cushion 24 is exposed such that the foam material is not covered by any other material and is thus able to contact the wearer. The exposed foam material provides a frictional surface to reduce slippage of the pad segment 20 on the shoulders of the wearer. Textured surfaces, e.g., small indentations, are provided on the upper surface 36 and lower surface 38 of the cushion body 24 to further reduce slippage and provide additional breathability.

As shown in FIGS. 1-4, the cushion portion 20 defines one or more grooves 26 in the cushion body 24. The grooves 26 extend from a first upper surface 36 to a second lower surface 38 of the pad body 24. The first surface is the surface of the pad that faces away from the user when the sling is in use, and the second surface faces toward the user when the sling is in use. The slots 26 are sized and configured to allow air to pass therethrough and release heat from the wearer's body, as well as to reduce the density and weight of the pad 24. The slots 26 may be formed in a chevron, rectangular, polygonal, circular, oval or other shape, or a combination thereof.

As shown in more detail in FIG. 4, the cushion portion 20 also includes a molding or binding 28 secured around the perimeter of the cushion body 24. In some embodiments, the hem 28 is stapled to the bolster 24. Alternatively, the hem 28 is glued or stapled to the cushion 24. The hem 28 is made of a durable, flexible material, such as nylon fabric, and provides additional strength to the cushion portion 20.

In some embodiments, at least a portion of the bolster body 24 may be covered by a fabric cover on the first surface of the sling 10 to provide additional strength, modify its appearance, or provide additional functionality. Preferably, the fabric cover is lightweight and includes an air permeable or moisture and air permeable textile for managing heat and moisture under the cushion. In some embodiments, the fabric cover may be fixedly attached to the sling 10, such as by being sewn, glued, or stapled into a fillet or hem 28. In embodiments where the sling 10 is used to carry luggage, the fabric cover may comprise the same fabric as is used for at least a portion of the body of the luggage. In other embodiments, the fabric cover may be removably attached to the sling 10 by fastener(s) proximate the first end 12 and/or the second end 14, such as clips, snaps, buttons, or hook and loop surfaces (e.g.,

). Depending on the intended use of the sling, a removable cover may be required to change the appearance of the sling. For example, a removable cover may be selectively used to increase the visibility of the user by using bright colors (e.g., bright orange) and/or reflective materials, or to decrease the visibility of the user by using a camouflage pattern selected, for example, based on the environment in which the sling is placed.

According to another aspect of the present disclosure, the sling 10 may include one or more holders 30, the one or more holders 30 configured to hold additional accessories, including additional ammunition or cartridges. As shown in fig. 1 and 3, the retainer 30 is made of a ring made of elastic fabric to fix the fitting to the cushion portion 20.

In some embodiments, the fabric cover described above may include additional features, such as retainers 30, clips, snaps, buttons, loops, hook and loop surfaces, pockets, or compartments to hold or attach small items to the sling 10.

As shown in fig. 2 and 5, the harness 18 may also include a built-in thumb ring 32 to enable the wearer to manipulate the sling around the wearer's body in a convenient manner. In some embodiments, thumb ring 32 is made of the same material as straps 16 and 18 and is sewn to pad portion 20.

In some embodiments, the first and second strap portions 16, 18 are connected by a middle strap portion, and the pad portion 20 is slidably disposed on the middle strap portion between the strap portions 16, 18 by one or more sleeve portions attached to opposite sides of the hem 28. For example, the fabric cover described above may be used as the sleeve portion. Alternatively, two or more straps made of the same material as straps 16 and 18 or hem 28 may be attached to hem 28 so that pad 20 may slide along the middle portion. The strap portions 16, 18 and the intermediate portion may comprise a single, integral strap. Alternatively, one or both of the strap portions 16 or 18 are adjustably connected to the intermediate strap portion by buckles 22 attached at respective ends of the intermediate portion, similar to the connection of strap portion 18 to strap portion 32. The slidable pad portion may allow for better customization to fit the user.

The sling 10 shown in fig. 1-5 is configured to carry a firearm (e.g., a long gun, such as a rifle or shotgun) or an item of luggage on one side of a user's shoulder, which may be on one side of the user (e.g., proximate the right shoulder, sides, and hips of the user) or on the fly (e.g., proximate the right shoulder of the user's body and across the user's body to the left hip). Thus, the sling 10 may be considered to be configured in a single shoulder configuration, 2 attachment point configuration. When using the sling in this manner, the user will typically carry items attached to the sling on the user's shoulders, proximate the user's upper back, to enable the user's arms and hands to move more freely.

In some embodiments, the lanyard 10 can be configured as a firearm (e.g., a pistol) carried in a shoulder holster, where the pistol is carried under the armpit of the user. In other embodiments, the lanyard may be configured to carry the firearm in a "ready" position proximate the chest of the user in addition to being carried on the shoulder.

It will be appreciated that when using the sling 10, a user may sometimes need to use one hand to stabilize or adjust an item to a preferred position, thereby limiting the full use of that hand. Therefore, it may be desirable to increase the mobility and freedom of movement of the user. Furthermore, when carrying heavy and/or cumbersome items (e.g., a large caliber shotgun or a large piece of luggage), using a single shoulder may be uncomfortable for the user if the item is carried for a long period of time (e.g., more than 30 minutes). Heavy and/or heavy items can be more comfortably carried in a more balanced manner. Accordingly, a sling system configured to be carried on both shoulders of a user (a double shoulder configuration) is contemplated herein, and in some embodiments, the sling of the present disclosure may include two or more pad portions 20.

In some embodiments, two slings 10 may be attached to a single item to allow for carrying by both shoulders. For example, two straps 10 may be attached to a firearm near the barrel end of the firearm using two connectors at the first end 12 and two straps 10 may be attached to the firearm near the stock of the firearm using two connectors at the second end 14. Alternatively, the strap portions 16 of two straps similar to the strap 10 are attached to a single connector at the first end 12 for connection to an item, and the strap portions 18 of the two straps are attached to two connectors at the second end 14 for attachment to an item (3 attachment point configuration). Alternatively, the strap portions 16 of two straps similar to the strap 10 are attached to a single connector at the first end 12 and the strap portions 18 of the two straps are attached to a single connector at the second end 14 for attachment to an item (2 attachment point configuration).

In some embodiments, the two straps or slings of the present disclosure may omit strap portion 16 and the connector at first end 12, and pad portion 20 is attached or connected directly to the item of luggage, such as by stitching, and second end 14 of strap portion 18 is attached directly to the item of luggage, such as by stitching, or is attached to the item by a connector at 14. Examples of such embodiments include backpacks.

In some embodiments, the pad portion 20 is configured to contact the user's body proximate the shoulders and a portion of the user's back (e.g., the upper back), and the sling includes a strap portion similar to the strap portion 18 and a second end 14 at the opposite end of the pad portion 20. One or more attachment points for attaching the sling to an article may be attached to the pad portion 20. For example, a lanyard configured in accordance with this embodiment may include an attachment point located near the center of the pad portion, i.e., proximate the center of the user's upper back, for attachment to a firearm. In other embodiments, two attachment points may be located on the pad portion proximate the user's shoulders, for example for attachment to a backpack. In these embodiments of the sling arrangement, the ends of the strap portion 18 may be releasably connected to an item such as a firearm or luggage, either directly or using a connector. In other embodiments, the strap portion 18 may be attached to the bottom of the pad portion 20. Additional attachment points for attachment to an item may also be connected to the bottom of the pad section. It will be appreciated that a wide variety of attachment points may be envisaged depending on the item that the sling is intended to carry. For example, a lightweight target rifle, such as a two-quarter rifle (biathlon rifle), which is different from a large caliber shotgun, may be mounted or attached to the strap, and both of these rifles are different from items of luggage, such as backpacks.

The sling system of the present disclosure, and in particular the pad portion 20, is not limited to padding the sling proximate the user's shoulder(s). For example, in some embodiments, the cushion portion is configured to be proximate a portion of the user's back. As described above, the single pad section can be proximate to the user's body at the shoulders and upper back.

In the embodiment shown in fig. 6A-6C, the pad portion is configured as a "back plate" that is worn proximate to the back of the user. The pad is generally configured in a quadrilateral shape, optionally having a concave curvature at one or more of the four sides, and four attachment points at the four corners. For example, the quadrilateral shape may be generally square (four equal sides), rectangular (two opposing sides having a first length and two other opposing sides having a second length), or trapezoidal (one pair of opposing sides having a first length and the remaining sides having a second length and a third length, respectively). The concave curvature of the sides may be curved at all four sides, or at opposite sides. In the embodiment shown in fig. 6A-6C, the top and bottom edges are not curved, and the lateral edges have a symmetrical concave curvature.

More specifically, the present invention provides a back plate for a sling system, comprising: a cushion comprising a single layer of closed cell foam defining a first surface and a second surface, and a plurality of channels extending from the first surface to the second surface; and a hem fixed to a periphery of the pad, wherein the pad is configured substantially in a quadrangular shape having four corners and four sides, each side independently selectively having a concave curvature; and four strap portions, each strap portion connected to the pad at one of the four corners, each strap portion including a coupling mechanism for connecting the back panel to an item.

Fig. 6A shows a view of the second surface of the back plate 600. Fig. 6B shows a front isometric view of the backplate 600 to illustrate the first surface. Fig. 6C shows a rear isometric view of the backplate 600 to illustrate the second surface of the backplate. The first surface is the surface of the pad that faces away from the user when the back plate is in use, and the second surface faces towards the user when the back plate is in use. In the embodiment of the back plate shown in these figures, the back plate 600 includes a pad portion 620, and the pad portion 620 includes a pad body 624. The pad portion 620 provides a comfortable fit against the wearer's body when the back plate 600 is worn and absorbs vibrations or shocks transmitted from a firearm or luggage attached to the back plate 600.

In the embodiment of the back panel shown in these figures, back panel 600 comprises a generally rectangular shape having a pair of opposing sides 601a and 601b, and a top side 602 and a bottom side 603, the pair of opposing sides 601a and 601b having a concave curvature, and the top side 602 and the bottom side 603 comprising generally straight sides. The upper corners 604a and 604b and the lower corners 605a and 605b are configured to provide attachment points for attaching the back plate 600 to another item (e.g., a chest bag described below). The upper corners 604a and 604b include flexible straps 616a and 616b, respectively. Lower corners 605a and 605b include straps 618a and 618b, respectively. The harnesses are depicted as they are worn by the user. Straps 616a, 616b, straps 618c and 618d, or straps 616a, 616b, 618c and 618d, may each include a length adjustment mechanism to lengthen or shorten the length of the straps to better fit the wearer. The length adjustment mechanism may include threading the strap through slot(s) in the buckle so that the effective length of the strap can be adjusted by varying the amount of the free end of the strap extending from the buckle. In the illustrated embodiment, the length of each of straps 616a, 616b, 618c, and 618d can be adjusted by threading the straps through slots in male end 640a of the side release buckle. This embodiment is not limiting. For example, the female end of the side release buckle may be used instead of the male end as shown. Alternatively, the length adjustment mechanism is similar to that shown in fig. 5, wherein a short strap portion is stitched to the pad portion 620 to support a buckle similar to buckle 22 of fig. 5, the buckle 22 of fig. 5 allowing for length adjustability of straps 616a, 616b, 618c, and/or 618 d. In still other embodiments, the short strap portion is connected to a male or female end of a side release buckle, and the length adjustment mechanism is embodied as another strap portion connected to the short strap portion using a complementary end of the side release buckle.

In some embodiments, pad 624 is made from a single layer of closed cell foam, such as Ethylene Vinyl Acetate (EVA) copolymer. The size of the pad 624 may vary as long as the pad 624 is configured to allow a firearm or luggage to be carried on the body of a user and to provide sufficient comfort to the user.

Pad portion 620 defines one or more slots 626 in pad body 624. The grooves 626 extend from a first surface 636 of the pad 624 to a second surface 638 thereof. The slots 626 are sized and configured to allow air to pass therethrough and to release heat and moisture from the wearer's body, and to reduce the density and weight of the pad 624. The grooves 626 may be formed in a chevron, rectangular, polygonal, circular, oval or other shape, or a combination thereof.

In an embodiment, the pad portion 620 also includes a fillet or hem 628 secured around the perimeter of the pad 624. In some embodiments, hem 628 is stapled to pad 624. Alternatively, the hem 628 is glued or stapled to the pad 624. The hem 628 is made of a durable, flexible material, such as nylon fabric, and provides additional strength to the pad portion 620.

In some embodiments, the pad 624 is exposed such that the foam material is not covered by any other material and is therefore able to contact the wearer. The exposed foam material provides a frictional surface to reduce slippage of the pad segment 620 on the back of the wearer. Textured surfaces, such as dimples, are provided on the upper surface 636 and lower surface 638 of the pad 624 to further reduce slippage and provide additional breathability.

In some embodiments, at least a portion of the pad 624 may be covered by a fabric cover on the first surface of the backboard 600 to provide additional strength, modify its appearance, or provide additional functionality. Preferably, the fabric cover is lightweight and includes a textile that is air permeable or moisture and air permeable for managing heat and moisture under the cushion. In some embodiments, the fabric cover may be fixedly attached to the backplate 600, for example sewn, glued or stapled into a fillet or hem 628. In embodiments where the back panel 600 is used to carry luggage, the fabric cover may comprise the same fabric used for at least a portion of the body of the luggage. In other embodiments, the fabric cover may be removably attached to the back panel 600 by fastener(s), such as clips, snaps, buttons, or hook and loop surfaces (e.g.,

). Depending on the intended use of the backplate, a removable cover may be required to change the appearance of the backplate. For example, a removable cover may be selectively used to increase the visibility of the user by using bright colors (e.g., bright orange) and/or reflective materials, or to decrease the visibility by using a camouflage pattern selected, for example, based on the environment in which the backplate 600 is locatedVisibility of the user.

Attachment points other than the four attachment points shown in fig. 6A-6C may also be included. For example, a back plate configured according to an embodiment may include an attachment point located near the center of the top edge 602, i.e., proximate the center of the user's upper back, for attachment to an item such as a firearm. In other embodiments, additional attachment points may be positioned on the pad portions proximate the user's shoulders, or at the corners 604a and 604b, and/or along the top edge 602, for example, for attaching a backpack to a back panel. Additional attachment points for attachment to an item may also be connected to the bottom of the pad section, either at corners 605a and 605b, and/or along bottom edge 603. It will be appreciated that a wide variety of attachment points may be envisaged depending on the item the backplate is intended to carry.

The backing plate as shown in figures 6A-6C may include a foundation for various liner harness configurations.

In an embodiment, the back panel may be attached to two slings or shoulder straps 10 of the configuration shown in fig. 1-5 at four attachment points to provide a cushion area for the shoulders and upper back of the user. The strap portion 16 of the sling may be directly attached to the upper attachment points at the corners 604a and 604b of the back panel, or they may be releasably connected, for example, by using side release buckles. The strap portion 18 may be adjustably attached to lower attachment points at the corners 605a and 605b of the back panel. Such a configuration with three pad sections 20 may be more adjustable and comfortable than a configuration with a single pad section 20. This configuration may be attached to a firearm or luggage item as previously described.

In an embodiment, the back panel 600 may be attached to a chest bag 800 worn by the user at four corner attachment points, as shown in fig. 7. A strap at the top of the chest bag 800 is releasably connected to the upper attachment point of the backboard. A strap at the lower portion of the chest bag 800 is releasably connected to the lower attachment point of the back panel.
