This application claims priority to U.S. Provisional Application Ser. No. 61/422,875, filed on Dec. 14, 2010, the contents of which are incorporated by reference.


TECHNICAL FIELD
The invention relates generally to mounting devices, and more particularly to a detachable swivel and associated mount.
BACKGROUND OF THE INVENTION
Conventional swivels can be used for a variety of equipment and objects, including firearms, weapons, safety items, life support products, emergency-type items, and common household goods. In certain instances, conventional swivels can be used to connect firearm sling to a firearm, such as an AR-15 or M-4. For example, a conventional swivel can be mounted to a forearm end or barrel of an AR-15 or other firearm and another conventional swivel can be mounted to a butt end or butt stock portion of the AR-15 or firearm. The conventional swivels can connect to opposing ends of a firearm sling, and the sling can be worn by a user to shoulder or otherwise carry the AR-15 or other firearm. An example conventional swivel is shown as 100 in FIG. 1.
In some instances, conventional swivels can be detached from the equipment or object they are mounted to by way of a push button release or rotating mechanism. In the example conventional swivel shown in FIG. 1, a rounded knob 130 can be rotated in either direction to retract a series of bearings 150 located in a lower portion 110 of the swivel. In other instances, a push button release located on the knob or side of the knob can be pushed to similarly retract a series of bearings located in a lower portion of the swivel. In any instance, due to the relative size of the release mechanisms involved, the manual operations of either rotating the knob or pushing a push button release on conventional swivels may be inconvenient or physically difficult to perform in certain circumstances. For example, if a user is wearing a sling mounted to a firearm via a conventional swivel 100 and sling loop 160, and the user becomes trapped or has limited movement, such as in a vehicular crash or when the physical environment is restrictive, releasing the sling and firearm from the user's body may be difficult or impossible if the user cannot rotate the knob or push the push button release associated with a conventional swivel to which the sling and sling loop 160 may be mounted to. In this example, failure to release the sling, sling loop 160, and firearm may lead to subsequent death or further injury to the user.

FIGS. 2 and 3 illustrate an example detachable swivel in accordance with an embodiment of the invention. FIG. 4 illustrates an exploded view of the detachable swivel 200 shown in FIGS. 2 and 3. In the example embodiment shown in FIGS. 2-4, a detachable swivel 200 is shown with a housing 202, an internal body 204, and one or more retention devices 206. In this embodiment, the housing 202 includes an upper cylindrical-shaped portion 208 and a lower cylindrical-shaped portion 210. A cylindrical-shaped axial cavity 212, into which the internal body 204 is operable to mount within, extends through both the upper cylindrical-shaped portion 208 and the lower cylindrical-shaped portion 210 of the housing 202. As shown in this embodiment, the internal body 204 can be an elongate-shaped device with an internal body mounting device hole 214, a first position bearing surface 216, a second position bearing surface 218, and a biasing surface 220, wherein the internal body 204 can axially translate within the axial cavity 212. The internal body mounting device hole 214 in an extended or exposed end 222 of the internal body 204 can be operable to receive a mounting device, such as a split ring 224 or cotter ring, when the internal body 204 is mounted within the axial cavity 212.
In one embodiment, the internal body can mount to a device for pulling the internal body in an axial direction. Examples of a device for pulling the internal body in an axial direction can include, but are not limited to, a threaded device, an eye loop, and a flexible cable.
In one embodiment, a housing such as 202 can be made from a stainless steel alloy.
In one embodiment, an internal body such as 204 can be made from a stainless steel alloy with an approximate length of 0.813 inches.
In one embodiment, a mounting device such as a split ring 224 can be made from zinc-plated steel with an outer diameter of about 0.740 inches, an inner diameter of about 0.596 inches, and a thickness of about 0.105 inches.
Each of the first position bearing surface 216, the second position bearing surface 218, and the biasing surface 220 can be formed or otherwise machined in an external surface of the internal body 204, wherein the first position bearing surface 216 and second position bearing surface 218 are operable to contact one or more of the retention devices 206. The one or more retention devices 206, such as a series of bearings 226A-226D, can be disposed between the internal body 204 and corresponding protrusions or holes 228 in the lower cylindrical-shaped portion 210 of the housing 202. One will recognize that any number of retention devices or bearings can be used in accordance with embodiments of invention, and the selection of the number may depend on the size of the associated swivel. When the internal body 204 is moved to a first position with respect to the housing 202, such as shown in FIGS. 2 and 3 as well as FIG. 5 described below, the one or more retention devices, such as bearings 226A-226D, can contact or otherwise seat against the first position bearing surface 216 of the internal body 204. Likewise, when the internal body 204 is moved to a second position with respect to the housing 202, such as shown in FIG. 6 described below, the one or more retention devices, such as bearings 226A-226D, can contact or otherwise seat against the second position bearing surface 218 of the internal body 204. As shown in FIG. 3, the relative depth of the first position bearing surface 216 is less than the depth of the second position bearing surface 218, thus when one or more bearings 226A-226D are in contact with a first bearing surface, such as 216, a portion of the bearings 226A-226D may extend outward from the protrusions or holes 228 in the lower cylindrical-shaped portion 210 and past an external surface 230 of the housing 202. Likewise, when one or more bearings 226A-226D are in contact with a second bearing surface, such as 218, a portion of the bearings 226A-226D may extend into the protrusions or holes 228 in the lower cylindrical-shaped portion 210 but remain retracted within the external surface 230 of the housing 202. Thus, when an axial force is applied to a portion of the internal body 204, such as an extended or exposed end 222 and away from the housing 202, the internal body 204 can axially translate within the axial cavity 212 between the first position and second position.
In one embodiment, each of a set of bearings such as 226A-226D can be made from stainless steel.
In certain embodiments, such as the embodiment shown in FIGS. 2-4, a detachable swivel 200 can include a spring 232 disposed or otherwise positioned between the biasing surface 220 of the internal body 204 and an internal surface 234 of the upper cylindrical-shaped portion 208 of the housing 202. Generally, the spring 232 is operable to bias the internal body 204 towards a first position with respect to the housing 202. When the internal body 204 is moved to a first position, such as shown in FIGS. 2, 3, and 5, with respect to the housing 202, the spring 232 can maintain a predefined force on the biasing surface 220 of the internal body 204 and can further maintain an opposing predefined force on the internal surface 234 of the upper cylindrical-shaped portion 208 of the housing 202. When the internal body 204 is moved to a second position, such as shown in FIG. 6, with respect to the housing 202, the spring 232 compresses and an increased force is applied to the biasing surface 220 of the internal body 204 and an opposing increased force is applied to the internal surface 234 of the upper cylindrical-shaped portion 208 of the housing 202.
In one embodiment, a spring such as 232 can be a coil-type compression spring made from 302 stainless steel, with a wire diameter of about 0.026 inches and approximately 9/16 inches in length (uncompressed).
In the embodiment shown in FIGS. 2-4, one or more housing mounting holes 236 can be formed in the upper cylindrical-shaped portion 208 of the housing 202. For example, a pair of housing mounting holes 236 can be formed or otherwise machined on opposing lateral sides of the housing 202. In any instance, these mounting holes 236 can be operable to receive a mounting device, such as a sling loop, similar to 160 in FIG. 1, or other sling mounting device.
Other swivel embodiments in accordance with the invention can include fewer or greater numbers of components and may incorporate some or all of the functionality described with respect to the components shown in FIGS. 2-4.
Example methods and processes which can be implemented with an example detachable swivel, such as 200 as well as other embodiments shown in FIGS. 2-4, 7-8, and 11-13, are described by reference to FIGS. 5-6, and 9-10.
FIGS. 5 and 6 illustrate an example use of a detachable swivel 500 in accordance with an embodiment of the invention. In the example embodiment shown, FIG. 5 shows an example detachable swivel 500 in a first or locked position within a corresponding socket hole 502, and FIG. 6 shows the example detachable swivel 500 of FIG. 5 in a second or unlocked position within the corresponding socket hole 502.
Generally, in use, a detachable swivel according to certain embodiments of the invention can be operable to mount to a corresponding hole in an object. For example, the housing 504 of the detachable swivel can fit into a corresponding hole or mounting cavity provided by a mount shown in FIGS. 15-17. By way of another example, the housing 504 of the detachable swivel 500 shown in FIGS. 5 and 6 can mount to a corresponding hole 502 in an object such as a firearm or associated mount 506. In other examples, an object can be a weapon, a sling, a belt, a carrying device, a garment, a safety item, a life support product, an emergency-type item, or a common household good. The hole 502 shown in FIGS. 5 and 6 can be a socket hole in a firearm, such as a socket hole in the buttstock end of a rifle or a socket hole near a forearm end of a rifle. When the detachable swivel 500 is initially aligned for insertion into the hole 502 of the firearm, a set of bearings 508 or detent devices associated with the detachable swivel 500 can extend outward 510 from an external surface 512 of the housing 504. As the housing 504 is inserted into the hole 502, the set of bearings 508 can contact the periphery of the hole 502. The insertion force upon the swivel 500 retracts the set of bearings 508 within the respective holes 514 in the external surface 512 of the housing 504. When the housing 504 is sufficiently inserted into the hole 502, the set of bearings 508 associated with the detachable swivel 500 can extend outward 510, in a first and locked position, from an external surface 512 of the housing 502. In the embodiment shown in FIG. 5, when the housing 504 is sufficiently inserted into the hole 502, the bearings 508 can extend within a circumferential groove 516, or series of corresponding dimples or grooves, within the periphery of the hole 502. In this manner, the housing 504 of the detachable swivel 500 can be maintained within the hole 502.
Typically, a mounting device 518 can be mounted to the detachable swivel 500 by way of an internal body 520 associated with the swivel 500. A sling mounting device similar to 160 in FIG. 1 can also be mounted to the detachable swivel 500 by way of holes or other mounts associated with the housing 504. In another embodiment, a cable and/or pull knob similar to 623, 624 in FIGS. 11-13 can be mounted to a detachable swivel.
When desired, the detachable swivel 500 can be removed from the hole 502. By applying an axial force to the internal body 520, and away from the housing 504, corresponding axial movement of internal body 520 causes the set of bearings 508 to be refracted within the respective holes 514 in the external surface 512 of the housing 504. That is, the set of bearings 508 can be retracted from the first or locked position, shown in FIG. 5, to a second or unlocked position, shown in FIG. 6. In particular, as shown in FIG. 6, as the internal body 520 moves axially (upward direction 522 shown in the drawing) the set of bearings 508 that are initially in contact with a relatively higher first position bearing surface 524 come into contact with a relatively lower second position bearing surface 526 of the internal body 520. In this manner, the set of bearings 508 can retract from the initial, first or locked position, to the subsequent, second or unlocked position. Upon refraction of the set of bearings 508, the housing 504 can be retracted from the hole 502, and thus, the detachable swivel 500 can be removed from the hole 502 or otherwise detached from the firearm 506.
In one embodiment, a swivel can be designed to permit removal of an internal body upon application of a predefined axial force. For example, a predefined axial force can be about 4 pounds of force.
FIGS. 7-8 illustrate another example detachable swivel in accordance with an embodiment of the invention. In the embodiment shown, the internal body can mount to a device for pulling the internal body in an axial direction. Examples of a device for pulling the internal body in an axial direction can include, but are not limited to, a threaded device, an eye loop, a flexible cable, a loop, a ring, and a pull knob.
FIGS. 9 and 10 illustrate an example use of the detachable swivel shown in FIGS. 7-8 in accordance with an embodiment of the invention. In the embodiment shown, when the device is manipulated, the internal body can be retracted from the locked position shown in FIG. 9 to the unlocked position shown in FIG. 10.
FIGS. 11-13 illustrate another example detachable swivel in accordance with an embodiment of the invention. The detachable swivel 600 shown in FIGS. 11-13 can operate similar to the detachable swivel shown in FIGS. 2-10, wherein an internal body of the detachable swivel can mount to a device for pulling the internal body in an axial direction and away from a housing associated with the detachable swivel causing the internal body to translate between a first and a second position. FIGS. 11 and 12 illustrate perspective views of the detachable swivel 600, and FIG. 13 illustrates a side sectional view of the detachable swivel 600 in FIGS. 11 and 12. The detachable swivel 600 is shown with a housing 602, an internal body 604, and one or more retention devices 606. In this embodiment, the housing 602 includes an upper cylindrical-shaped portion 608 and a lower cylindrical-shaped portion 610. An axial cavity 612, into which the internal body 604 is operable to mount within, extends through the upper cylindrical-shaped portion 608 and the lower cylindrical-shaped portion 610 of the housing 602. As shown in this embodiment, the internal body 604 can be an elongate-shaped device with an internal body mounting device 614, a first position bearing surface 616, a second position bearing surface 618, and a biasing surface 620, wherein the internal body 604 can axially translate within the axial cavity 612. The internal body mounting device 614 at extended or exposed end 622 of the internal body 604 can be operable to receive a mounting device, such as a cable 623 mounted to a relatively large pull knob 624, when the internal body 604 is mounted within the axial cavity 612.
In one embodiment, a pull knob such as 624 can have a hole, such as 625, machined through a portion of the knob 624 to receive one end of a cable, such as 623. Once the cable 623 is threaded through the hole 625, the knob 624 can be retained on the cable 623 by a retention device fitted to the cable 623 or by another means or device applied to the cable 623 and/or knob 624. As shown in FIGS. 11-13, a pull knob such as 624 can be shaped with a generally spherical end connected to a conical portion end, wherein the conical portion end is adjacent to the housing 602.
Similar to the embodiment in FIGS. 2-10, each of the first position bearing surface 616, the second position bearing surface 618, and the biasing surface 620 can be formed or otherwise machined in an external surface of the internal body 604, wherein the first position bearing surface 616 and second position bearing surface 618 are operable to contact one or more of the retention devices 606. The one or more retention devices 606, such as a series of bearings 626A-626D, can be disposed between the internal body 604 and corresponding protrusions or holes 628 in the lower cylindrical-shaped portion 610 of the housing 602. One will recognize that any number of retention devices or bearings can be used in accordance with embodiments of invention, and the selection of the number may depend on the size of the associated swivel. When the internal body 604 is moved to a first position with respect to the housing 602, similar to that shown in FIGS. 2, 3 and 5, the one or more retention devices, such as bearings 626A-626D, can contact or otherwise seat against the first position bearing surface 616 of the internal body 604. Likewise, when the internal body 604 is moved to a second position with respect to the housing 602, similar to that shown in FIG. 6, the one or more retention devices, such as bearings 626A-626D, can contact or otherwise seat against the second position bearing surface 618 of the internal body 604. Similar to that shown in FIG. 3, the relative depth of the first position bearing surface 616 is less than the depth of the second position bearing surface 618, thus when one or more bearings 626A-626D are in contact with a first bearing surface, such as 616, a portion of the bearings 626A-626D may extend outward from the protrusions or holes 628 in the lower cylindrical-shaped portion 610 and past an external surface 630 of the housing 602. Likewise, when one or more bearings 626A-626D are in contact with a second bearing surface, such as 618, a portion of the bearings 626A-626D may extend into the protrusions or holes 628 in the lower cylindrical-shaped portion 610 but remain retracted within the external surface 630 of the housing 602. Thus, when an axial force is applied to a portion of the internal body 604, such as an extended or exposed end 622 and away from the housing 602, the internal body 604 can axially translate within the axial cavity 612 between the first position and second position.
In certain embodiments, such as the embodiment shown in FIGS. 11-13, a detachable swivel 600 can include a spring 632 disposed or otherwise positioned between the biasing surface 620 of the internal body 604 and an internal surface 634 of the upper cylindrical-shaped portion 608 of the housing 602. Generally, the spring 632 is operable to bias the internal body 604 towards a first position with respect to the housing 602.
