The present disclosure relates generally to firearms accessories. In particular, but not by way of limitation, the present disclosure relates to systems, methods and apparatuses for quickly attaching and detaching an adapter to a firearm configured for coupling to a sling.
Slings are regularly used with firearms to allow for a convenient method of carry and for weapon retention in dynamic environments. Traditional slings mount onto the bottom of a weapon at two points, fore and aft, allowing for suitable carry over long distances and may be used as a steadying aid to improve weapon accuracy. While it offers the user the ability to carry the weapon comfortably over the shoulder or securely across the back, the traditional, bottom-mounted 2-point sling hinders weapon usage in dynamic combat environments since the weapon is stowed in a non-useable orientation. While 2-point slings may be used in combat as an accuracy aid by being wrapped around the arm or other techniques, this encumbers the user through entanglement in the sling itself and is mostly useful only for long-range engagements.
Due to these limitations, side-mounted 2-point or 3-point slings were developed to allow for improved usage as these systems allow the user to carry a weapon comfortably on the front of the body in a usable low-ready position instead of over the back or shoulder. These systems typically incorporate the ability to carry over-the-back or shoulder, like a traditional sling, since these carry positions are useful for climbing, swimming, low (belly) crawling or when maximum frontal dexterity is needed when carrying supplies or wounded. While these slings were a major improvement over the traditional sling, they primarily were intended for use from a single-side and require manual adjustment to allow for transitions from side-to-side in dynamic situations. Additionally, due to the amount of strap material used to wrap around the body, they can also interfere with chest-mounted equipment, such as on load-bearing vests. Traditionally, sling swivels have been used to secure slings to the weapon. These swivels have taken many forms but they all have similar characteristics: namely, they are rotatable (swivel) about a point and are usually an elongated loop through which sling material may be threaded. They have been positioned on either side of the weapon, so that the sling may be said to be mounted on either side, or on the upper and lower surfaces of the weapon, so that the sling may be said to be mounted along the weapon, or a combination thereof.
However, such swivel slings can encumber or entangle the user and thus require quick detachment from the firearm. The quick detach or “QD” interface was thus developed in order to enable rapid removal of a sling from a firearm. The QD interface includes a “QD socket” including a female portion of the interface and a QD body including a male portion of the interface. The QD socket (sometimes referred to as a “swivel socket”) typically includes an axial cavity sometimes having an annular ring into which a portion of the QD body can selectively couple to. The QD body typically includes some type of loop or bail for either threading a sling through or for coupling to via a clip such as the snap clip illustrated in U.S. Design Pat. 679,580 or as described in U.S. Pat. No. 8,544,153. The QD body also typically includes a “connection post” that fits into and interfaces with the axial cavity of the QD socket. In particular, many QD bodies feature an internal spring loaded plunger that biases a plurality of ball bearings through the QD connection post. The ball bearings then interface with a ridge in a QD socket and hold the QD body in place. When desired, the user depresses the plunger and the bias on the ball bearings is removed, allowing them to roll into the casing and thereby allowing the QD body to be removed from the QD socket.
Some exemplary QD sockets include the EZ CARBINE QD SWIVEL ATTACHMENT POINT from DANIEL DEFENSE, and the RAIL MOUNT QD SLING SWIVEL from DANIEL DEFENSE, to name a few. Some exemplary QD bodies include the QUICK-DETACH SLING SWIVEL from VLTOR WEAPON SYSTEMS, the QD SLING SWIVEL from DAMAGE INDUSTRIES, the QD SWIVEL from DANIEL DEFENSE, and the HEAVY DUTY FLUSH BUTTON SWIVEL from MI, to name a few.
Popularity of the QD interface has led manufacturers to include QD sockets on many firearms and firearms accessories and has led many users to add QD sockets to their firearms. However, the QD body is often large and adds weight to a firearm. Also, the QD interface is believed by some to be vulnerable to detachment under severe static and dynamic force situations. Thus, there is a need for an adapter able to couple to a QD socket but having lighter weight, smaller size, and a more reliable and/or semi-permanent coupling mechanism than existing QD bodies.
Exemplary embodiments of the present invention that are shown in the drawings are summarized below. These and other embodiments are more fully described in the Detailed Description section. It is to be understood, however, that there is no intention to limit the invention to the forms described in this Summary of the Invention or in the Detailed Description. One skilled in the art can recognize that there are numerous modifications, equivalents and alternative constructions that fall within the spirit and scope of the invention as expressed in the claims.
The present invention can provide a system and method for modifying a QD connection.
In one exemplary embodiment, the present invention can include an adapter for a QD socket. The adapter has a first post portion having a longitudinal axis, a loop, and a first contact tab shaped to interface with a QD socket, and a second post portion having a second contact tab shaped to interface with a QD socket. The second post portion is coupled to the first post portion and movable between a first configuration defining a first transverse distance between the first and second contact tabs and a second configuration defining a second transverse distance between the first and second contact tabs. The first transverse distance is greater than the second transverse distance.
Another exemplary embodiment includes a method of modifying a quick disconnect attachment. The method includes providing an adapter assembly having a plurality of contact tabs, the plurality of contact tabs movable between a first configuration having a first transverse distance between the plurality of contact tabs and a second configuration having a second transverse distance between the plurality of contact tabs, the first transverse distance greater than the second transverse distance. The method further includes loosening the adapter assembly to cause the adapter assembly to move from the first configuration to the second configuration. The method further includes inserting a distal portion of the adapter into a QD socket, and orienting a loop on the adapter assembly to a desired position. The method further includes tightening the adapter assembly to cause the adapter assembly to move from the second configuration to an engagement configuration wherein the first and second contact tabs engage the QD socket to maintain the adapter assembly attached to the QD socket in a semi-permanent manner.
Another exemplary embodiment includes an adapter for a QD socket having a connection post having a plurality of contact tabs movable relative to each other between a first configuration and a second configuration. The first configuration defines a maximum effective outer diameter of the connection post, and the second configuration defines a minimum effective outer diameter of the connection post.
As previously stated, the above-described embodiments and implementations are for illustration purposes only. Numerous other embodiments, implementations, and details of the invention are easily recognized by those of skill in the art from the following descriptions and claims.
Various objects and advantages and a more complete understanding of the present invention are apparent and more readily appreciated by reference to the following Detailed Description and to the appended claims when taken in conjunction with the accompanying Drawings wherein:
The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
The present disclosure relates generally to firearms accessories. In particular, but not by way of limitation, the present disclosure relates to systems, methods and apparatuses for quickly attaching and detaching an adapter to a firearm configured for coupling to a sling.
Herein disclosed is an adapter that avoids the weight and size of a traditional QD body by using a smaller and lighter fixed loop or other fixed attachment point. Overcoming the risk of a traditional QD body unintentionally detaching from a QD socket, the herein disclosed adapter includes various attachment means used to fix the adapter to a QD socket (either allowing some, minimal, or no rotation depending on the QD socket) in a semi-permanent manner. In one embodiment, a wedged design is used (see
The direction of lateral movement can be controlled by an optional guide ridge 114 in the lower portion 104 that interfaces with an optional guide valley 116 in the upper portion 102. The optional guide ridge 114 and the optional guide valley 116 can be shaped and sized so as to fit into each other. In the illustrated embodiment, the guide ridge 114 and the guide valley 116 are arranged parallel to a plane that passes through the adapter from a front to a back and from a top to a bottom of the adapter 100. In some embodiments, the guide ridge 114 has a seat 114a that has an abutting surface perpendicular to a longitudinal axis of the connection post and a nesting seat 114b having an abutting surface parallel to the longitudinal axis. In other non-illustrated embodiments, other planes for lateral movement can be used and thereby effect different directions of lateral movement between the upper and lower portions 102, 104.
The connection post 108 includes a tab 118 on a front side (part of the upper portion 102) and a tab 120 on a back side (part of the lower portion 104). As the upper and lower portions 102, 104 move laterally relative to each other, the tabs 118, 120 move laterally apart and thus increase an effective outer diameter of the connection post 108 and hence enable the tabs 118, 120 to lock into an annular groove in a QD socket. While mere pressure from the adapter 100 on the inner diameter of a QD socket can prevent swiveling of the adapter 100, in some cases a QD socket can include a discontinuous annular groove or other openings in a side of the QD socket that the tabs 118, 120 can fit into and thereby prevent swiveling of the adapter, or at least prevent more than a set amount of swiveling.
The screw 110 passes through an elongated slot 130 in the upper portion 102 as seen in
An effective outer diameter of the adapter 100 has been discussed throughout this disclosure. The effective outer diameter is a maximum diameter of portions of the connection post 108 that interface with a QD socket as illustrated in
In some embodiments, and as illustrated in
The angled interface 112 can have an angle of approximately 30° when measured relative to a horizontal plane passing through front, rear, and sides of the adapter 100 (i.e., parallel to the page in
In
As seen most clearly in
While a loop 106 has been illustrated and described, this attachment means is not limited to a loop or to the particular shape of a loop shown and described. Other attachment means may also be implemented without deviating from the intent and scope of this disclosure.
In some alternative embodiments, the adapter 100 can exclude one or both of the tabs 118, 120. For instance, where no tabs are implemented, the QD socket to which the adapter 100 is to be coupled may not have an annular groove for the tabs 118, 120 to engage.
While a guide ridge and valley 114, 116 have been illustrated, other alignment or guidance mechanisms can be used to ensure that the upper and lower portion 102, 104 move laterally relative to each other along a single plane.
While a screw 110 has been illustrated and described as the mechanism to apply force between the upper and lower portions 102, 104 and thereby expand or decrease the effective outer diameter of the connection post 108 interfacing with a QD socket, other means can be used such as a screw passing through slots in both the upper and lower portions 102, 104 (no threading) and a washer or nut below the lower portion 104. This is just one non-limiting example of other means that can be used to apply vertical force between the upper and lower portions 102, 104.
