This disclosure relates generally to weapons sights and more specifically to sights for a firearm, such as front and rear sights for a handgun.
Firearms operators have traditionally used some type of sights to improve aiming thereby assisting in making a shot impact a target at a desired location. For example, rifles and pistols often include a front sight and a rear sight mounted on the barrel, where the operator aligns the front sight (e.g., a post) with the rear sight (e.g., a notch or V) to establish a sight picture that includes the intended target. Such sights may be referred to as “iron sights” since they traditionally have been made of metal. Other sights may be configured as optical or telescopic sights. It is desirable for the user of a weapon to be able to adjust the sights as needed to improve accuracy.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and, together with a general description provided herein, and the detailed description of the embodiments given below, serve to explain the principles of the present disclosure.
The figures depict various embodiments of the present disclosure for purposes of illustration only. Numerous variations, configurations, and other embodiments will be apparent from the following detailed discussion.
Disclosed herein is a front sight assembly and a rear sight assembly for a firearm. In one example, the rear sight has a sight body that includes an elevation arm connected at its distal end to the body and extending proximally therefrom to a sight portion, where the elevation arm and the body comprise a monolithic structure. A cam body is below the elevation arm and has a cam surface in contact with a bottom surface of the elevation arm, where the cam body is rotatable to change a vertical position of the sight portion.
In one example, a front sight assembly includes a sight body defining a longitudinal bore. For example, the bore extends through proximal and distal portions that extend upward from a base portion. A sight element can be retained or is disposed in the longitudinal bore. For example, the sight element is an optical fiber. A proximal end of the longitudinal bore has a reduced size so as to retain the sight element in the bore. At a distal end, a retention pin is disposed in a retention bore that extends transversely to and intersects the longitudinal bore such that the retention pin occupies a distal portion of the longitudinal bore to retain the sight element. For example, the retention bore extends vertically through a bottom surface of the sight body. The retention pin can be retained in the retention bore when the sight body is attached to a handgun slide or barrel of a firearm, for example.
The front and sights can be used together, separately, or in combination with other sight assemblies on a wide variety of host firearms, including, but not limited to semiautomatic handguns configured for duty use, concealed carry, competitive shooting, and recreation. Sight assemblies disclosed herein can similarly be used on long guns, such as rifles and shot guns, as will be appreciated.
Examples of some host firearms for the front sight and/or rear sight described herein, include the P365™, P226™, P320™, P938™ and other handguns manufactured by Sig Sauer®, Inc. Other suitable host firearms will be apparent in light of this disclosure. As will be further appreciated, the particular configuration (e.g., materials, dimensions, etc.) of the front sight and rear sight as described herein may vary, for example, depending on the intended use and particular firearm to which each sight is mounted. Numerous configurations will be apparent in light of this disclosure.
Sights for a weapon, such as a handgun, long gun, practice gun or other device are desired to be as accurate as possible, thereby ensuring the desired point-of-impact (POI) is attained. The sights for handguns typically include a front sight and a rear sight that are used in conjunction to aim the handgun. It is an embodiment of this disclosure that the front and rear sights may be used separately or together.
Traditionally, fiber optics are placed into a sight to provide contrast between a front sight and a rear sight. These fibers are sized such that they fit into the hole in the sight body. To retain the fiber in the hole, the ends can be melted. This approach to retaining the fibers in the sights can fail and the fibers may fall out of the hole as a result. This new approach prevents loss of fiber optic and enables change of the fiber optic by the consumer.
As described herein, a front sight body is introduced that has a longitudinal bore. The proximal end of the bore has a reduced diameter so as to retain a fiber optic rod in the bore. The front of the longitudinal bore is intersected by a retention bore extending through the sight body. After the fiber optic rod is installed into the sight body, a retention pin is inserted into the retention bore of the sight body. The retention pin protrudes into the support bore, capturing the fiber optic rod or other sight element. The sight body is then attached to the slide, locking the retention pin in place. Indeed, it is an advantage that the fiber optic rod does not need to be melted to be held in the sight body. The fiber optic can also be removed and replaced without being cut, so the end user can install a different fiber optic rod if desired. For example, the user can change colors of the sight's optical fiber as desired without armorer training.
Also disclosed is an adjustable sight apparatus that has a unitary body that includes an adjustable rear sight body and an elevation arm. In one example, the elevation arm is continuous with a middle portion of the sight body and extends rearward between and separate from lateral portions of the sight body. Being made of a flexible and resilient material, the elevation arm can be displaced to adjust the vertical position of the sight portion of the rear sight assembly. For example, a cam between the top of the handgun slide and the bottom of the elevation arm can be rotated to adjust the vertical position of the elevation arm. In some embodiments, the cam body includes flats on an outer surface of the cam body. Actuation of the cam in a desired direction causes deflection of the elevation arm such that the elevation arm adjusts the rear sight body.
As discussed herein, terms referencing direction, such as upward, downward, vertical, horizontal, left, right, front, back, etc., are used for convenience to describe embodiments of firearm sights aligned horizontally. Embodiments of the present disclosure are not limited by these directional references and it is contemplated that the disclosed sights could be used in any orientation.
The following examples illustrate particular properties and advantages of some of the embodiments of the present disclosure. The features and advantages described herein are not all-inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims. Moreover, it should be noted that the language used in the specification has been selected principally for readability and instructional purposes and not to limit the scope of the disclosed subject matter.
Also as shown in
The front sight 122 and rear sight 120 are described in more detail below. The front sight 122 and rear sight 120 may be used together, as shown and described herein; however, for illustration purposes, the front sight 122 and rear sight 120 will be described using associated figures. Additionally, the front sight 122 and rear sight 120 can be used or provided individually or together as part of a complete handgun, as part of a slide assembly, or as replacement parts for a firearm. Further, while described in the context of a handgun, the front sight 122 and rear sight 120 can be used with other types of firearms, including rifles and shotguns. Numerous variations and embodiments will be apparent in light of the present disclosure.
As described herein the distal portion 130 may be referred to as a distal housing, a distal support, or a front portion. The proximal portion 132 may be referred to as a proximal housing, a proximal support, or a rear portion. In this example, the distal portion 130 and proximal portion 132 extend up from the base 138. Base 138 can also be referred to as a support portion or sight body. An orifice, or hole, also referred as a support bore or longitudinal bore 136, is formed through the distal portion 130 and through the proximal portion 132. The support bore or longitudinal bore 136 of proximal portion 132 may be used to hold or support a sight element 134. In some embodiments, the longitudinal bore 136 is also formed in part in the base 138, such as defining an open channel along the top of the base 138 between the distal portion 130 and the proximal portion 132. In yet other embodiments, part of the longitudinal bore 136 extends through the base 138 and can be closed along its length, such as when the sight element 134 does not use ambient light. In some embodiments, part of the longitudinal bore 136 between the proximal portion 132 and distal portion 130 may be semi-circular in shape, or trough-shaped, with an open upper region, such that the upper half of the sight element 134 is exposed to ambient light when installed. For example, the longitudinal bore 136 may have a “half-pipe” design between the proximal housing 132 and distal housing 130.
A sight element 134, such as a length of material, a fiber, a filament, a fiber optic rod, or self-luminous tube, for example, can be retained in the longitudinal bore 136 that passes through the proximal portion 132 and the distal portion 130. Part of the sight element 134 may be exposed to ambient light for the purpose of illuminating the proximal end of the sight element 134. For example, a top surface and portions of side surfaces of sight element 134 can be exposed to the ambient light either directly or via a translucent cover (not shown). The sight element 134 may have properties that allow the sight element 134 to collect and direct ambient light to illuminate an end the sight element 134 that is visible to the user through the proximal end of the longitudinal bore 136. This enhances the ability of a user to see the front sight 122.
Retention pin 148 is disposed in a retention bore 149. The retention pin 148 is retained in the retention bore 149 between the slide 128 and the closed top of the distal portion 130 of the front sight 122. The retention bore 149 is oriented in any suitable direction and houses retention pin 148. The retention pin 148 occupies part of the longitudinal bore 136 in the distal portion 130 of the front sight 122, such that the sight element 134 is prevented from escaping from the front of front sight 122. The retention bore 149 may be any suitable design configuration, such as horizontal, vertical, diagonal, or any suitable angle. In the example shown, the retention bore 149 extends through a bottom surface of the distal portion 130 of the front sight 122 and intersects the longitudinal bore 136. In other embodiments, the retention bore 149 and retention pin 148 could extend through a side or top of the distal portion 130. In an alternate embodiment, the retention bore 149 may be at any angle on the distal portion 130. While a vertical orientation is shown, it is envisioned that a suitable screw, which may be counter-sunk into distal portion 130, could be used to hold retention pin 148 in an orientation that is other than vertical.
The retention pin 148 is disposed such that the retention pin 148 at least partly blocks the longitudinal bore 136 to retain the sight element 134 therein. Indeed, the position of retention pin 148 in retention bore 149 prevents the sight element 134 from extending beyond the front surface 153 of distal portion 130. The retention pin 148 can be a roll pin, a fastener, a length of fiber optic rod, a dowel pin, or other structure that is received in the retention bore 149. The retention bore 149 can be a smooth bore or threaded as appropriate for the corresponding retention pin 148. In one example, the retention bore 149 is threaded and the retention pin 148 is a set screw or similar fastener.
The front sight 122 also includes proximal portion 132 with associated portion of the longitudinal bore 136. The sight element 134 is retained in the longitudinal bore 136 in part by the reduced second diameter 145 at the proximal end of the longitudinal bore 136 in the proximal portion 132. Thus, the sight element 134 is retained at proximal and distal ends (as shown by distal portion 130 and proximal portion 132) to prevent loss of the sight element 134.
As discussed above, the longitudinal bore 136 in the distal portion 130 is intersected by a retention bore 149 extending through the bottom of the base 138. The retention pin 148 protrudes into the longitudinal bore 136 in the distal housing or distal portion 130 to obstruct the sight element 134 from sliding out of the longitudinal bore 136. The front sight 122 can then be attached to the slide 128, locking the retention pin 148 in place. In doing so, the retention pin 148 can but need not engage the retention bore 149; in other words, the retention pin 148 can be loosely retained in the retention bore 149 between the slide and the closed upper end of the retention bore 149.
The rear sight 120, as described herein, uses a one-piece sight body 152 that acts as a support for the rear sight and that includes an adjustable elevation arm 168. A cam 188 between the elevation arm 168 and the slide 128 can be moved to deflect the elevation arm 168 away from the slide 128 in varying amounts for the purpose of adjusting a vertical position of the aiming portions of the rear sight.
The term “living hinge” may refer to a flexure bearing made from a single piece of material that connects two bodies of the same material. A rear sight 120 assembly according to the present disclosure includes a body 152 made as a single piece of material that includes an elevation arm 168. The elevation arm can 168 bend with respect to the body 152 due to the flexibility and resiliency of the material. In one embodiment, the elevation arm 168 extends between lateral portions 152a, 152b of the body 152 such that the elevation arm is free-floating along its length with respect to lateral portions 152a, 152b. In some embodiments, the rear sight 120 may operate by bending the material of the elevation arm 168. For example, the thickness and other dimensions of the body 152 and the elevation arm 168 can be selected to provide the desired flexibility, range of motion, and resilient force to resume a resting position. In some embodiments, the elevation arm 168 can be thinned or scored along its length and/or at specific locations, such as adjacent the junction between the elevation arm 168 and the body 152, to increase flexibility and/or to promote bending at a desired hinge point.
A plastic living hinge may be manufactured by an injection molding operation that forms the parts in a single piece. It is contemplated that a living hinge between elevation arm 168 and body 152, as described herein may be formed by injection molding of materials comprising polyethylene, polypropylene, nylon, glass-reinforced nylon, or other flexible and resilient materials. Properties of the living hinge are related to the properties of the material and dimensions (e.g., length, thickness) of the elevation arm 168, for example.
Elevation arm 168 is shown as a sloped, longitudinal portion of body 152. Any suitable design of elevation arm 168 is within the scope of this disclosure. The elevation arm 168 can be deflected using a cam 188 to change the elevation of sight portion 172, and to also change the elevation of aiming portions 173 and 174 (when present) such that a user can adjust the sight picture of the firearm as required for accurate shooting. This aiming typically includes alignment of aiming portions 173 and 174 with a front sight, such as front sight 122 as described herein.
In the example shown, the body 152 defines fastener orifices 176 and 178 through lateral portions 152a, 152b, respectively, which can be used for mounting the rear sight 120 to the top of a handgun slide 128 using fasteners. The rear sight 120 can similarly be mounted to the top of a receiver, barrel, or other top surface of a firearm. The elevation arm 168 is connected to a middle portion 152c of the body 152 and extends rearwardly between lateral portions 152a, 152b to a sight portion 172. The elevation arm 168 is spaced from and is discontinuous with each lateral portion 152a, 152b along longitudinal gaps 155 so as to be free floating with respect to the lateral portions 152a, 152b of the sight body 152. The elevation arm 168 and sight portion 172 can have a T-shape in some embodiments. As shown, the sight portion 172 includes left and right aiming portions 173, 174 attached to the sight portion 172. The left and right aiming portions 173, 174 extend above the top surface of the elevation arm 168 and define a gap or sight opening 175 between them. For example, the aiming portions 173, 174 and top surface of the elevation arm 168 define a rectangular channel through which the user can view the front sight 122. In other embodiments, the sight portion 172 defines or includes aiming portions 173, 174 as an integral part of the sight portion 172 rather than as separate components. For example, the sight portion 172 defines a U-shaped channel through which the front sight 122 is visible when aiming the gun.
A cam 188 (not visible; shown in
In one embodiment, the cam 188 has a generally cylindrical shape with a cam surface that is eccentric about the axis of rotation. Accordingly, rotating the cam 188 with the cam surface in contact with the bottom of the elevation arm 168 causes a greater or smaller distance between the elevation arm 168 and the axis of rotation of the cam 188, therefore resulting in the desired deflection of the elevation arm 168 to adjust the height of the sight portion 172. The amount of deflection of elevation arm 168 is based, at least in part, on the length of the elevation arm 168, position of the cam 188 along the elevation arm 168, amount of cam rotation, and profile of the cam surface, for example. In other embodiments, the cam 188 can be a wedge that slides laterally or longitudinally between the elevation arm 168 and the firearm. For example, the wedge-shaped cam can be advanced or retracted using a screw-drive accessible from the side or proximal end of the rear sight 120.
Aiming portions 173 and 174 form part of a sight picture that can include the front sight 122, as described herein, to aim the handgun. In some embodiments, each aiming portion 173, 174 defines a cavity in which an associated sight element 162, 164 can be housed. Specifically, sight element 162 is housed in left aiming portion 173 and sight element 164 is housed in right aiming portion 174. For example, sight elements 162, 164 can be an optical fiber exposed to ambient light along at least part of its length. In other embodiments, sight elements 162, 164 can be or can include a self-luminous tube, such as a tritium vial. In yet other embodiments, sight elements 162, 164 can be or include aiming indicators (e.g., a dot or square) of reflective or high-visibility material, of other suitable material on the rear face of the aiming portions 173, 174, for example. In some embodiments, aiming portions 173, 174 can use a combination of a fiber optic rod, a self-luminous tube, and high-visibility material. In some embodiments, the aiming portions 173, 174 alternately or additionally can include a dot, tritium vial, reflective surface, or other indicator that is visible to the user at least in lighted conditions. As will be appreciated, when sight elements 162, 164 are optical fibers, the exposed portion of the sight elements 162, 164 can contribute to the apparent brightness of the rear sight 120 in daylight or other lighted conditions.
In some embodiments, the sight portion 172 at the proximal end of the elevation arm 168 is configured as an attachment point for aiming portions 173, 174. In one example, the sight portion 172 extends crosswise to, and defines a T with, the longitudinal portion of the elevation arm 168. In some such embodiments, the aiming portions 173, 174 can be attached individually or as a single assembly to the sight portion 172 using a snap fit, a fastener, or other suitable method.
Fastener orifices 176 and 178 are designed to provide a via for fasteners 177, 179 (not visible) to attach the rear sight 120 to a slide 128. For example, the fastener openings 176, 178 can be threaded or smooth bores configured to receive corresponding fasteners 177, 179 that are arranged to accommodate the desired hole pattern in the slide 128. In embodiments where machine screws or other fasteners (e.g., 177, 179) are used to secure the rear sight 120, the fasteners 177, 179 can extend vertically through the rear sight 120 at fastener openings 176, 178.
In some embodiments, the aiming portions 173, 174 are adjustably mounted to the sight portion 172 of the elevation arm 168, such as for windage adjustment. Right/left adjustment can be actuated with an Allen wrench, hex wrench, a screwdriver, or other suitable tool adjusting a position of the rear sight 120. Opening 156 may receive a fastener that is part of the right/left adjustment.
In one embodiment, a windage blade (visible to user) holds the sight elements 162, 164, which may be, for example, a fiber optic. For example, fiber optic cords are clamped between the body of the aiming portion 173, 174 and the sight portion 172 of the elevation arm 168. In other embodiments, sight element 162 is disposed in a bore defined in left aiming portion 173 and sight element 164 is disposed in a bore defined in right aiming portion 174. Sight elements 162, 164 can be a fiber, a fiber optic rod, a self-luminous tube, or other suitable material. Typically, the sight elements 162, 164 of the rear sight 120 will be of the same color, and that color will be different than the sight element 134 of the front sight 122. The use of different color fibers between the front sight and rear sight enhances contrast and improves the ability for a user to properly align the front and rear sight for aiming, but the use of different colors is not required.
The cam 188 is disposed below the elevation arm 168 and has a cam surface in contact with a bottom surface of the elevation arm 168. The cam 188 is rotatable to change a vertical position of the sight portion 172 with respect to the lateral portions 152a. 152b of the sight body 152. Protrusion 190 extends down from a bottom surface of the body 152. As noted above, the cam 188 can be accessed through an opening (e.g., opening 158 shown in
The monolithic sight body 152, which includes elevation arm 168 and sight portion 172, utilizes the characteristics of flexible and resilient polymer to function as a living hinge. The elevation arm 168 can be deflected by the use of a cam 188, optionally having flats around its circumference. Flats on the cam 188 can interface with surfaces of the body 152 and/or the slide 128 to maintain the position of the cam 188 and provide tactile feedback to the user. In its deflected state, the resiliency of the material results in the elevation arm 168 exerting a downward force on the cam 188, causing the flats 191 to press against the body 152 and/or slide 128, for example.
