Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is a non-provisional application of U.S. Provisional Patent Application No. 63 / 362,103 filed on March 29, 2022, and claims priority, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to viewing optics, and more particularly to protective covers for viewing optics. Background Art

[0004] Rifle scope lenses are often subject to environmental factors, which can cause dust and dirt to cover the lens, or worse, cause damage to the lens. Protective covers exist to prevent these problems. In addition, these protective covers can be easily kept on rifle scopes because they are usually stored on the optics. In addition, users of rifle scopes have used alignment apertures (also known as parallax reduction aperture stops, aperture caps, or aperture limiters) in conjunction with their rifle scopes. Aperture caps can be used to align rifle scopes and prevent parallax (i.e., displacement of objects due to errors in the lens). However, these aperture caps are mainly used for indoor dry-gun shooting training.

[0005] While protective caps and aperture caps exist, there are no caps that can perform both functions and purposes. These caps have been developed as separate components, requiring the user to keep track of both caps. When these caps are separate components, this can be problematic because it is relatively easy for the user to lose one or both of the caps. Additionally, even if the caps are not lost, the user faces the added stress of managing more items while using their rifle scope.

[0006] Eventually, if the user cannot track both covers at the same time, or if the user finds it difficult to track both covers, the user will decide to use the rifle scope without the aperture cover. Without the aperture cover, the user will not be able to align. Without aligning the aperture, the user will experience additional parallax problems, which will lead to reduced aiming accuracy and bring great impact when using the rifle scope.

[0007] Therefore, there is a need for a protective cover for viewing optics that can also fulfill the role of an aperture cover. Summary of the invention

[0008] In one embodiment, the present disclosure is directed to a "zero cap" that alleviates the problems associated with keeping track of two separate caps. As disclosed herein, the zero cap serves as both a protective cap and an aperture cap. In one embodiment, the zero cap can be attached to a viewing optic. The zero cap has multiple functions, but as one component, preventing the user from having to manage several components and potentially losing them.

[0009] The zero point cap disclosed herein not only improves ease of use, but also improves accuracy for the user. The user can easily connect the alignment aperture to their viewing optics and can easily calibrate their optics. This results in improved accuracy and reduced frustration when using the viewing optics.

[0010] Additionally, the lens of the viewing optics remains clean due to the zero point cap. Often, debris and dust find their way into the viewing optics. While users can have a protective cap, they cannot have the protective cap and alignment aperture in one cap. Having a single cap perform both functions increases accuracy, reduces frustration, prevents misplacement and loss, and reduces clutter on the lens.

[0011] In one embodiment, the present disclosure relates to a zero point cover, comprising: a base; an aperture cover configured to be connected to the base by a hinge; and a cover plug configured to rotate on the aperture cover. In one embodiment, the base comprises a first opening and a first connection mechanism. In another embodiment, the first opening is configured to be attached to a viewing optic; and the first connection mechanism is configured to receive a pin that connects the first connection mechanism to other connection mechanisms.

[0012] In one embodiment, the aperture cover comprises a plurality of holes and a second connection mechanism. The aperture cover may have more than two holes. In one embodiment, the plurality of holes are respectively configured to receive one of a plurality of plugs. In another embodiment, the second connection mechanism is configured to receive a pin that connects it to other connection mechanisms.

[0013] In one embodiment, the cover plug includes a first stopper and a second stopper.

[0014] In one embodiment, the present disclosure relates to a zero point cover comprising: a base configured to be connected to an observation optical lens; an aperture cover configured to be connected to the base via a hinge and having a first hole and a second hole, wherein the second hole is located below the first hole; and a cover plug having a first plug and a second plug, wherein the first plug is configured to interact with the first hole and the second plug is configured to interact with the second hole.

[0015] In one embodiment, the base has an opening configured to attach to an outer connecting strip of the viewing optic.

[0016] In one embodiment, the first hole of the aperture cover is located at the center of the aperture cover.

[0017] In one embodiment, the present disclosure is directed to a viewing optic comprising a zero point cap as described herein. In yet another embodiment, the present disclosure is directed to a rifle scope comprising a zero point cap as described herein.

[0018] In one embodiment, the present disclosure relates to an observation optical scope, which includes a zero-point cover and a connecting strip, wherein the zero-point cover has a base, an aperture cover configured to be connected to the base via a hinge, and a cover plug configured to rotate on the aperture cover, and the connecting strip is configured to interact with the base.

[0035] definition

[0036] Numerical ranges in the present disclosure are approximate, and therefore unless otherwise specified, may include values ​​outside the range. Assuming that there are at least two units of separation between any lower value and any higher value, numerical ranges include all values ​​from the lower limit to the upper limit in increments of one unit and including the lower limit and the upper limit. As an example, if the composition, physical or other properties, such as molecular weight, viscosity, etc., are from 100 to 1000, it is expected that all individual values ​​such as 100, 101, 102, etc. are clearly enumerated, and sub-ranges such as 100 to 144, 155 to 170, 197 to 200, etc. are clearly enumerated. For the range containing a value less than 1 or the range containing a fraction greater than 1 (e.g., 1.1, 1.5, etc.), one unit is appropriately considered to be 0.0001, 0.001, 0.01 or 0.1. For the range containing a single digit less than 10 (e.g., 1 to 5), one unit is typically considered to be 0.1. These are only examples of what is specifically intended, and all possible combinations of values ​​between the lowest value and the highest value enumerated are to be considered to be expressly stated in the present disclosure.Among other things, ranges of values ​​are provided within the present disclosure for distances from a user of the device to a target.

[0037] The term "and / or" as used herein in phrases such as "A and / or B" is intended to include both A and B; A or B; A (alone); and B (alone). Similarly, the term "and / or" as used in phrases such as "A, B, and / or C" is intended to include each of the following embodiments: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).

[0038] As used herein, "ballistics" is a way of accurately calculating the trajectory of a bullet based on many factors.

[0039] As used herein, an "erector sleeve" is a protrusion from an erector lens mount that engages a slot in an erector tube and / or cam tube, or serves a similar purpose. It may be integral with the mount, or may be removable.

[0040] As used herein, an "erecting tube" is any structure or device having an opening that receives an erecting lens base.

[0041] As used herein, the term "firearm" refers to any device that propels an object or projectile, for example, in a controllable flat shot, line of sight or line of departure, for example, a pistol, a rifle, a shotgun cartridge gun, a muzzle-loading rifle, a single-shot rifle, a semi-automatic rifle, and a fully automatic rifle in any caliber direction through any medium. As used herein, the term "firearm" also refers to a remote servo-controlled firearm, wherein the firearm has automatic sensing of position and direction cartridge orientation. The shooter can position the firearm in one position and move to a second position for target image acquisition and aiming. As used herein, the term "firearm" also refers to a chain gun, a belt-fed gun, a machine gun, and a Gatling gun. As used herein, the term "firearm" also refers to a high-altitude and over-the-horizon projectile propulsion device, such as an artillery, a mortar, a cannon, a tank cannon, or a rail gun of any caliber.

[0042] As used herein, in one embodiment, a "reticle" is an aiming pattern used with a viewing optic, such as but not limited to a crosshair aiming dot or other aiming pattern.

[0043] As used herein, the term "viewing optics" refers to a device used by a shooter or observer to select, identify, or monitor a target. "Viewing optics" may rely on visual observation of the target, or, for example, rely on infrared (IR), ultraviolet (UV), radar, heat, microwave or magnetic imaging, radiation (including X-rays, gamma rays, isotope particle radiation), night vision, vibration receivers (including ultrasound, acoustic pulses, sonar, seismic vibrations, magnetic resonance), gravity receivers, broadcast frequencies including radio waves, television and cellular receivers, or other images of the target. The image of the target presented to the shooter by the "viewing optics" device may be unchanged, or may be enhanced, for example, by magnification, expansion, subtraction, superposition, filtering, stabilization, template matching, or other means. The target selected, identified, or monitored by the "viewing optics" may be within the shooter's line of sight, or tangent to the shooter's line of sight, or the shooter's line of sight may be blocked while the target acquisition device presents the shooter with a focused image of the target. The image of the target acquired through the "viewing optics" may be, for example, analog or digital, and may be transmitted, for example, via video, physical cables or wires, IR, radio waves, cellular connections, laser pulses, optics, 802.11b or other wireless transmissions, such as using protocols such as html, SML, SOAP, X.25, SNA, Bluetooth, etc. TM , Serial, USB or other suitable image distribution method, to share, store, archive or transmit within a network of more than one shooter and observer. The term "viewing optics" may be used interchangeably with "optical sight".

[0044] As used herein, the term "scene" refers to a real-world scene, including but not limited to objects.

[0045] As used herein, the term "shooter" applies to an operator who conducts the shooting or an individual who cooperates with an operator who conducts the shooting and observes the shooting.

[0046] Understanding the purpose and function of the alignment aperture is essential to further understanding the present disclosure. The reticle is used to assist the shooter in hitting the target. The reticle can be made of a variety of materials, including optical materials like optical glass or plastic. The reticle can be made of any transparent or translucent material. In one embodiment, the reticle is composed of wires, spider webs, nanowires, etchings, or printing. The reticle can also be constructed using projections onto the material from mirrors, videos, holographic projections, or other means. The etching can be filled with reflective material that emits light when the light is switched in a variable resistance manner to increase or decrease the light intensity. The reticle can be mounted anywhere between the eyepiece and the objective lens of the scope. There are two key alignment functions performed when installing a rifle scope.

[0047] In one embodiment, the reticle may be an electronic reticle from an active display projected into the first focal plane of the viewing optics.

[0048] Two key calibration functions include zeroing the weapon and aligning the laser rangefinder. First, zeroing the weapon generally refers to the process of aligning the etched (passive) reticle with the weapon's point of impact when firing at a target. Second, the integrated laser rangefinder (LRF) is aligned using an alignment chart. The alignment chart details the position of the LRF's co-aligned visible laser relative to the passive reticle. For illustration purposes, imagine that the user is attempting to use a rifle scope and needs to align the LRF. The user places the alignment chart at a predetermined distance from the observation point. The user then aims the weapon, optic, and passive reticle at the designated point. The user then adjusts the LRF's visible laser to align with the relevant point on the alignment chart.

[0049] The steps included in the calibration function may seem simple, but even a well-trained and experienced person may face problems caused by parallax. As mentioned above, parallax is the displacement of an object due to errors in the lens. However, the problem can be solved by using an aperture cap that attaches to the front of the rifle scope. The aperture cap limits the aperture diameter, ultimately reducing errors. Zeroing the weapon can be done at 25 meters. Aligning the LRF with passive and active reticles can be done at 10 meters.

[0050] As described above, the zero point cap disclosed herein is a combined protective cap and aperture cap. This eliminates the difficulty and stress of managing multiple caps and keeping track of various components when using a rifle scope. The protective cap is typically attached to a rifle scope, and the zero point cap can be similarly attached to a rifle scope.

[0051] In one embodiment, the zero point cover can be used as an aperture cover when the protective cover is closed and the cover plug is removed from one end to rotate out of the light path. The user can then observe through the hole in the center (where the cover plug has been rotated away); in this example, the user is observing through the restricted objective lens aperture.

[0052] The cover plug features two plugs, each for attaching to a hole in the aperture cover. When the top plug is in the top hole on the aperture cover, the zero cover can be used for protection because both holes are plugged and prevented from entering debris. When the top plug is rotated and not in the top hole on the aperture cover, the zero cover can be used for zeroing and laser rangefinder alignment. To prevent the cover plug from falling off the aperture cover, the bottom plug remains in the bottom hole on the aperture cover when the zero cover is used for protection or calibration. This prevents the cover plug from being misplaced or lost.

[0053] The zero cap can be used for a variety of different purposes, but the following are some representative examples. The zero cap can be used on an LRF mounted to a passive reticle of a rifle scope, as long as the LRF has a co-aligned visible laser and the user has the correct alignment card for the rifle scope and LRF combination. The zero cap can be used for indoor dry-fire training. The zero cap can also be used to zero a weapon with a traditional rifle scope or magnified optic for between 10 and 100 meters.

[0054] Figure 1 The figure shows an exploded view of the components of the zero point cover in environment 1. The zero point cover includes several components: base 20, aperture cover 35 and cover plug 55. In one embodiment, the zero point cover is attached to a rifle scope. The rifle scope 5 includes an opening 10 and an outer connecting strip 15.

[0055] In one embodiment, the outer connecting strip 15 is a protruding lip on the rifle scope 5. The outer connecting strip 15 is designed to be mechanically connected to a cover, which in one embodiment is a zero point cover. The outer connecting strip 15 is preferably capable of being attached to a base 20 of the zero point cover. The base 20 has an opening 25 that is configured to be attached to the outer connecting strip 15 in a manner known in the art. The base 20 has a connecting mechanism 30 that has a hole that is designed to receive a hinge pin (not shown) for connecting to another connecting mechanism.

[0056] In one embodiment, the connection mechanism 30 is connected to the aperture cover 35. The aperture cover 35 has a connection mechanism 40 with a hole designed to receive a hinge pin (not shown) for connection. In one embodiment, the hinge pin can be passed through the connection mechanism 30 of the base 20 first, and then through the connection mechanism 40 of the aperture cover 35, and then out through the other side of the connection mechanism. The hinge pin keeps the two pieces (base 20 and aperture cover 35) connected, while also allowing the aperture cover 35 to hinge around the base 20.

[0057] In one embodiment, the aperture cover 35 has two holes on its face. In one embodiment, the top hole 45 is placed at the center of the surface of the aperture cover 35. The bottom hole 50 is preferably placed below the top hole 45 and offset from the center of the surface of the aperture cover 35.

[0058] The top hole 45 and the bottom hole 50 are designed to receive a plug, respectively. In one embodiment, the top hole 45 and the bottom hole 50 receive plugs from the cover plug 55. The cover plug 55 has two plugs (a top plug 60 and a bottom plug 65). The top plug 60 is designed to be placed in the top hole 45, while the bottom plug 65 is designed to be placed in the bottom hole 50. The bottom plug 65 is designed to stay in the bottom hole 50.

[0059] In one embodiment, the bottom plug 65 is able to rotate within the bottom hole 50. This rotation allows the top plug 60 to be removed from the top hole 45 and does not interfere with opening the aperture cover for alignment. The top plug 60 can be removed from the top hole 45, thereby moving around the aperture cover 35. This movement creates an entire line of sight through the top hole 45 for the user. The top plug 60 is designed to be removed from the top hole 45 while the bottom plug 65 remains within the bottom hole 50.

[0060] In one embodiment, the aperture cover has at least two holes on its face.

[0061] Figure 2 The figure shows a side view of the fully connected zero point cover 2. The zero point cover 2 includes a base 20, an aperture cover 35, and a cover plug 55. The base 20 and the aperture cover 35 are connected via a hinge pin 70. As shown, the top plug 60 and the bottom plug 65 of the cover plug 55 are fully integrated with the top hole 45 and the bottom hole 50 of the aperture cover 35, respectively. The plugs are connected in a manner that eliminates the entry of debris into the interior of the zero point cover 2.

[0062] Figure 3 The figure shows a side perspective view of the cover plug 55. As shown, the top plug 60 is configured to allow the top plug 60 to be removed from the top hole 45 (as described above) while the cover plug 55 remains connected to the aperture cover 35. The bottom plug 65 is designed to remain in the bottom hole 50 even when the top plug 60 is disengaged (as described above). This is preferred because the cover plug 55 does not need to be removed from the aperture cover 35. Overall, the cover plug 55 can remain connected to the zero point cover 2, preventing the cover plug 55 from being misplaced or lost.

[0063] Figure 4 The figure shows a front view of the aperture cover 35. The aperture cover 35 preferably has a top hole 45 and a bottom hole 50. In one embodiment, the top hole 45 is located at the optical center of the rifle scope concentric with the objective lens. The bottom hole 50 is preferably located below the top hole 45. In one embodiment, the bottom hole 50 serves as an interface with the cover plug 55 (as described above) and remains connected to the bottom plug 65 even when the top hole 45 is open.

[0064] Figure 5 The zero point cover 2 is shown in the protective position 3a in use (from Figure 2 ).like Figure 2 As shown, the zero point cover 2 is fully connected. The base 20 is connected to the rifle scope 5. The aperture cover 35 is connected to the base 20 by a hinge. In one embodiment, the cover plug 55 is connected to the aperture cover 35 in a manner that does not expose and open any holes on the aperture cover 35. In this position, the zero point cover 2 performs its protective function.

[0065] Figure 6 The zero point cover 2 is shown in use in the zero position 3b (from Figure 2 ).like Figure 2 As shown, the zero point cover 2 is fully connected. The base 20 is connected to the rifle scope 5. The aperture cover 35 is connected to the base 20 by a hinge. In one embodiment, the cover plug 55 is connected to the aperture cover 35 in a manner that the top hole 45 of the aperture cover 35 is open. In this position, the aperture cover 2 performs its alignment function.

[0066] Figure 7 The zero point cover 2 is shown in the open position 3c in use (from Figure 2 ).like Figure 2 As shown, the zero cover 2 is fully connected but not fully closed. The base 20 is connected to the rifle scope 5. The aperture cover 35 is connected to the base 20 by a hinge. In one embodiment, and as illustrated here, the aperture cover 35 has been rotated about the hinge pin 70 so that the opening 25 of the base 20 and the opening 10 of the rifle scope 5 are fully accessible and open. The cover plug 55, not fully shown here, is connected to the aperture cover 25. In one embodiment, the top plug 60 is fully integrated with the top hole 45 of the aperture cover 25, and the bottom plug 65 is fully integrated with the bottom hole 50 of the aperture cover 25. In this position, the zero cover 2 performs its open function and the firearm can be fired.
