Description

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

This disclosure relates generally in the field of optical sights for firearms.

2. Background Art

A conventional variable power optical sight for a firearm includes a magnification ring configured to be manually rotated about an optical axis of the optical sight to change the magnification of the optical sight to a desired magnification. Because some magnification rings are not easily rotatable manually due to poor surface texture and/or positioning along an optical sight, users often attach a raised tab or lever to a magnification ring to assist with manipulating the magnification ring to more quickly and/or more accurately adjust the magnification of the optical sight. One traditional raised lever or “throw lever” includes a cylindrical clamp portion configured to attach to a magnification ring in a manner similar as a pipe clamp and a lever portion extending out from the clamp portion radially from the optical axis of the optical sight. Due to diametrical differences in magnification rings of various optical sights, a user is often required to use a different throw lever for each of his/her specific optical sights.

Because a traditional throw lever extends out from an optical sight, the throw lever is subject to snagging or catching on items like clothing, user gear, as well as brush and the like when using the optical sight outdoors. To combat this problem, some detachable throw levers have incorporated a hinge in the clamp portion of the throw lever allowing the throw lever to be flipped up and down about the clamp portion. However, cylindrical clamp portions of flip up throw levers are larger or thicker than a traditional clamp portion in order to accommodate a hinge feature. In still other instances, optical sights are manufactured to include a flip up throw lever of a permanent configuration with a spring and detent built into a magnification ring of the optical sight allowing the throw lever to be flipped up and down about the magnification ring. However, a magnification ring of this type is larger than a traditional magnification ring due to the added space required to house the spring and detent. A flip up throw lever is desired that overcomes the above shortcomings.

In another embodiment, the disclosure is related to a throw lever device for manipulating a turnable ring of a cylindrical member. Although a throw lever device of this disclosure may be built to scale, in one embodiment a throw lever device is sized for manual operation with one or more turnable magnification rings of one or more firearm optical sights.

In another embodiment, the disclosure is related to a turnable lever device for manipulating a turnable ring of a cylindrical member.

As described herein, a throw lever or “throw lever device” of this disclosure is operationally configured for use with a magnification ring of an optical sight including, but not limited to a magnification ring of a firearm optical sight. With reference to FIGS. 1-4, when attached to a magnification ring 501 of a firearm optical sight 500 (hereafter “optical sight 500”), a throw lever device 100 may be directed to a fixed non-operable position as shown in FIGS. 1 and 2 and directed to at least a first fixed operable position as shown in FIGS. 3 and 4. At an operable position, the throw lever device 100 may be used to manually turn a corresponding magnification ring 501 in either direction for purposes of adjusting magnification of an optical sight 500. As described herein, in an embodiment a throw lever device 100 may be used interchangeably amongst a plurality of optical sights 500. For example, a throw lever device 100 may be provided as part of a system comprising a plurality of optical sights 500 each having a magnification ring 501 operationally configured to receive a throw lever device 100 in releasable attachment thereto.

With reference to FIGS. 5 and 6, in an embodiment a throw lever device 100 may comprise a main seat or base member 110 operationally configured as a mounting member of the throw lever device 100 that is releasably attachable to a mount surface 505 of a magnification ring 501 of an optical sight 500. In this embodiment, the throw lever device 100 further includes a lever member 120 pivotally attached to the base member 110 about a rotational axis in a manner effective to set the lever member 120 to a fixed non-operable position and to a fixed operable position similar as described above in reference to FIGS. 1-4.

In the embodiment of FIGS. 5 and 6, the base member 110 includes a mounting surface 121 operationally configured to contact or mate with a mount surface 505 of a magnification ring 501 of one or more optical sights 500. Suitably, the mounting surface 121 comprises a surface configuration operable with the mount surface 505. For example, the mounting surface 121 may include a planar surface for contacting a planar mount surface 505. In another embodiment, the mounting surface 121 may include a non-planar surface or other surface configuration and a mount surface 505 may include one or more conformal contacts for the mounting surface 121. In another embodiment, the mounting surface 121 may include a curved surface having a radius of curvature the same or substantially similar as the radius of curvature of a corresponding magnification ring 501.

In the embodiment of FIG. 5, the base member 110 includes one or more through holes 101 corresponding to one or more threaded holes 506 disposed along the mount surface 505 whereby the base member 110 may be releasably fastened to the magnification ring 501 via one or more threaded fasteners 122. Suitable threaded fasteners 112 may include, but are not limited to socket head cap screws, countersunk screws, flathead screws, and combinations thereof. As such, the one or more through holes 101 may be of a type effective to receive one or more particular types of threaded fasteners 112 there through. For example, a through hole 101 may include a counterbore hole as shown in FIG. 5 for receiving a socket head cap screw 122. In another non-limiting example, a through hole 101 may include a countersunk hole for receiving a countersunk screw or flathead screw as understood by the skilled artisan. According to the configuration of the base member 110 as described above, in an embodiment a plurality of optical sights 500 may each comprise a mount surface 505 the same or similar as shown in FIG. 6 whereby the throw lever device 100 may be used as an interchangeable member with each of the optical sights 500.

Turning to FIGS. 7-10, in another embodiment a throw lever device 100 may be releasably attached to a magnification ring 501 of an optical sight 500 via one or more intermediary members such as a mounting interface 105 operationally configured as a uniform attachment for the throw lever device 100 regardless the outer diameter of the magnification ring 501. In other words, a mounting interface 105 as shown in FIGS. 7-10 provides a mount surface of an unvarying size for a corresponding throw lever device 100 regardless the outer diameter of the magnification ring 501 to which the mounting interface 105 is secured. As such, a single throw lever device 100 may be mounted to different optical sights 500 having magnification rings 501 of different outer diameters.

Similar as described above, a lever member 120 of this embodiment is pivotally attached to the base member 120 and may be oriented or set to a fixed non-operable position and to a fixed operable position for turning a corresponding magnification ring 501. A throw lever device 100 of this disclosure may include a one piece lever member 120 of a predetermined length, size and shape. In another embodiment, a throw lever device 100 may include two or more interchangeable lever members 120 of varying length and/or size and/or shape. As shown in FIGS. 7-10 and as described below, in another embodiment a lever member 120 may be comprised of an assembly of components operationally configured to establish a lever member 120 of a desired length and/or size and/or shape.

As shown in FIG. 11, when a lever member 120 of a throw lever device 100 as shown in FIGS. 7-10 is set to a fixed non-operable position (or “flip down” position), a central longitudinal axis A-A of the lever member 120 is parallel to an optical axis B-B of a corresponding optical sight 500. As shown in FIG. 12, when the lever member 120 is set to a fixed operable position (or “flip up” position), the central longitudinal axis A-A is perpendicular to the optical axis B-B wherein the lever member 120 is operationally configured as a radially extending member relative optical axis B-B. In an embodiment, when the throw lever device 100 is set to a fixed operable position the lever member 120 may comprise a length whereby the lever member 120 extends out from a corresponding optical sight 500 a distance greater than any other exterior components of the optical sight 500 as shown in FIG. 12. In another embodiment, the lever member 120 may include a length whereby one or more other exterior components of a corresponding optical sight 500, e.g., a turret 502 of the optical sight 500, may extend out from the optical axis B-B a distance greater than the lever member 120. In another embodiment, a lever member 120 may extend out from the optical axis B-B a distance the same or substantially similar as one or more other exterior components of a corresponding optical sight 500. In still another embodiment, a throw lever device 100 may be operationally configured so that the lever member 120 extends out from a corresponding optical sight 500 in a fixed operable position with the central longitudinal axis A-A set at an angle between 0.0 degrees and 90.0 degrees relative optical axis B-B.

As stated above, although a throw lever device 100 of this disclosure may be built to scale, for manual operation a lever member 120 includes a length and/or size and/or shape suitable to be manipulated by one or more fingers of a hand of a user or other person when secured to a magnification ring 501 of an optical sight 500 whereby force applied to the lever member 120 in either direction applies torque to the corresponding magnification ring 501 for turning the magnification ring 501 in the same direction as the lever member 120. In one non-limiting embodiment, a distal end of a lever member 120 may extend out from a circumferential surface 503 of a corresponding magnification ring 501 at a distance ranging from or about 2.99 cm to or about 4.34 cm (from or about 1.178 inches to or about 1.71 inches). In addition, a lever member 120 for use with an optical sight 500 may include an outer width or outer diameter ranging from or about 0.88 cm to or about 1.0 cm (from or about 0.346 inches to or about 0.394 inches). Suitably, a force may be applied at any point along the length of the lever member 120 for applying a desired torque to a corresponding magnification ring 501. In another embodiment, a lever member 120 may be manually operated to turn a corresponding magnification ring 501 when the lever member 120 is oriented or set to a fixed non-operable position as shown in FIG. 11.

As described below, arresting of the lever member 120 in either a fixed non-operable position or a fixed operable position about the base member 110 is achieved according to the configuration of the base member 110 and the lever member 120. In particular, a lever member 120 of this disclosure includes a detent assembly that is axially disposed about the lever member 120, i.e., axially disposed about the central longitudinal axis A-A of the lever member 120, and operationally configured to be biased against different surfaces of the base member 110 to establish different fixed positions of the lever member 120. By incorporating a detent assembly as part of the lever member 120 the size of a body of a corresponding magnification ring 501 is minimized providing a low profile throw lever device 100, mounting interface 105 and magnification ring 501 combination.

With reference to FIGS. 13 and 14, a throw lever device 100 for use with a mounting interface 105 may comprise an assembly of components including a base member 110 and a lever member 120 pivotally attached thereto. In this embodiment, the lever member 120 comprises an assembly including a post member 125, an annular plunger 130, one or more biasing members 135, an annular boss member 140, an annular retaining ring 145, an optional annular first extension member 150 and a threaded fastener, e.g., a set screw 155, coaxial with longitudinal axis A-A. Herein, the post member 125, the plunger 130, the boss member 140 and the one or more biasing members 135 are collectively operationally configured as a detent assembly of the throw lever device 100. In this embodiment, because the lever member 120 carries the one or more biasing members 135, the amount of space afforded within the lever member 120 allows for an increase in size and/or stiffness and/or strength of the one or more biasing members 135 compared to a conventional detent requiring a biasing member housed in a magnification ring of an optical sight. For purposes of this disclosure, a detent assembly may also be referred to as a “biased detent assembly.”

Still referring to FIGS. 13 and 14, in this embodiment the mounting interface 105 comprises a first male dovetail surface 106 for forming a first dovetail joint with a corresponding slot type female dovetail mount surface 505 of a magnification ring 501 as shown in FIG. 15. As such, it is herein contemplated that a plurality of optical sights 500 may be provided each having a magnification ring 501 with a female dovetail mount surface 505 as shown in FIGS. 15-17 whereby each mounting interface 105 operates as a universal type mounting interface 105 for a throw lever device 100. As shown, a base member 110 for use with a mounting interface 105 of this embodiment comprises a slot type female dovetail mount surface 111 for forming a second dovetail joint with a second male dovetail surface 107 of the mounting interface 105 as shown in FIGS. 8, 10 and 15. Accordingly, a mounting interface 105 of this embodiment includes two male dovetail connectors or surfaces operationally configured to form two dovetail joints for releasably attaching a throw lever device 100 to a magnification ring 501.

As understood by the skilled artisan, a mounting interface 105 of a particular size and shape may determine a minimum circumference magnification ring 501 to be used with the mounting interface 105. In other words, when using a mounting interface 105 of a particular size and shape, a body of a magnification ring 501 must be large enough to include a corresponding female dovetail mount surface 505 for receiving the mounting interface 105 therein as shown in FIG. 15. For example, in a non-limiting embodiment including a mounting interface 105 having a height of or about 4.30 mm (0.17 inches) and a first male dovetail connector 106 having an outer width of or about 8.10 mm (0.32 inches), a corresponding a female dovetail mount surface 505 suitably comprises a depth of or about 3.0 mm (0.19 inches) from a circumferential surface 503 of the magnification ring 501 and an inner width for receiving the first male dovetail connector 106 of or about 9.80 mm (0.39 inches). In another embodiment, a circumferential surface 503 of a magnification ring 501 may include additional material forming part of the body of the magnification ring 501 of a size suitable for forming a female dovetail mount surface 505 therein.

In an embodiment, including a first male dovetail connector 106 and a second male dovetail connector 107 of equal or substantially equal outer widths as depicted, a female dovetail mount surface 111 of a base member 110 suitably includes an inner width the same or substantially similar as the inner width of a female dovetail mount surface 505.

With reference to FIGS. 13 and 14, the mounting interface 105 may include one or more threaded countersunk holes 108 and 109 for receiving set screws 160 and 161 at a depth therein whereby the proximal ends 160A and 161A of the set screws 160 and 161 extend out past a mating surface 164 of the mounting interface 105 (see FIG. 22) for mating with corresponding female surfaces 507 and 508. e.g., cavities, dimples, disposed along the female dovetail mount surface 505 of a magnification ring 501 of an optical sight 500 (see FIG. 17) in a manner effective to load the threads of the set screws 160 and 161 and tension the mounting interface 105 during operation of the throw lever device 100 by forcing the first male dovetail surface 106 against the female dovetail mount surface 505. In addition, the base member 110 may include one or more threaded holes 165 and 166 for receiving set screws 168 and 169 there through in a manner effective for the proximal ends 168A and 169A of the set screws 168 and 169 to mate with the countersunk holes 108 and 109 of the mounting interface 105 (sec FIG. 22). As such, the length of the set screws 160 and 161 is suitably less than the depth of the threaded holes 108 and 109 so that the proximal ends 168A and 169A of the larger diameter set screws 168 and 169 are free to mate with the countersunk holes 108 and 109 in a manner effective to load the threads of the set screws 168 and 169 and tension the mounting interface 105 during operation of the throw lever device 100 by forcing the second male dovetail surface 107 against the female dovetail mount surface 111 of the base member 110.

In an embodiment, a mounting interface 105 may be releasably attached to a female dovetail mount surface 505 of a magnification ring 501. In another embodiment, a mounting interface 105 may be permanently attached to a female dovetail mount surface 505 of a magnification ring 501 via one or more adhesives for adhering the set screws 160 and 161 within the threaded holes 507 and 508. Suitable adhesives for use with set screws 160 and 161 may include, but are not limited to threadlocker adhesives and two-part epoxy compositions. For purposes of this disclosure, when a mounting interface 105 is operably attached to a magnification ring 501, in an embodiment the mounting interface 105 may be considered as part of the magnification ring 501 whereby attaching a throw lever device 100 to a mounting device 105 may be also be referred to as attaching the throw lever device 100 to the magnification ring 501.
