Description

DUAL POWER OPTIC ASSEMBLY

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 542,406, filed October 4, 2023, the entire disclosure of which is incorporated by reference herein.FIELD OF THE INVENTION

[0002] The subject matter described herein generally relates to a dual power optic assembly for use with a firearm, as well as systems and methods relating thereto.BACKGROUND OF THE INVENTION

[0003] No single weapon sight exists with an effective range that matches that of an assault rifle. At present, two categories of weapon sights are typically employed with assault rifles: short range (e.g., between 1 and 150 meters) and medium range (e.g., between 50 and 600 meters), each that have shortcomings. For example, short-range weapon sights, including red dots and holographic sights (collectively, reflex sights), can have an unlimited eye box and provide a faster target acquisition relative to other sight types in close-quarter battles (CQB). However, short range sights often utilize reticles that can obscure a target at longer ranges, and do not typically provide magnification to aid in identification and aiming. Medium-range weapon sights can utilize fixed power prism optics (e.g., for 3x to 6x magnification) or variable power lens optics (e.g., for 2x to lOx magnification), which enables target identification and engagement at longer ranges that are not possible with reflex sights. However, medium-range weapons have too narrow a field of view for effective close quarter engagement, often disrupting a user's ability to aim at close range targets.

[0004] Prior attempts to bridge these two categories and address these shortcomings have been unsuccessful. For example, flip-to-the-side magnifiers can be added to reflex sights and provide 3x to 6x magnification. However, because one hand must be removed from the weapon to change magnification, these devices can be subject to downtime during a magnification change, wherein the target cannot be engaged. Moreover, downtime forces the user to reacquire the target after completing the magnification change. Another disadvantage of flip-to-the-side magnifiers is that the magnifier also magnifies the dot in the reflex sight, which obscures longer range targets. Further, the magnifier itself can be physically awkward when flipped to the side of the weapon, creating an additional snag hazard.

[0005] As another example, a red dot short-range sight co-mounted with a fixed magnified optic can provide 3x to 6x magnification. In some configurations, the red dot sight can bemounted above or at an angle to the side of the fixed magnified optic. In these configurations, the user must shift their head or the weapon to an awkward position to see through the red dot, which can lead to less controllable weapon recoil, increased user fatigue, and, ultimately, reduced weapon accuracy. In addition, mounting the red dot sight can be physically awkward and create an additional snag or poke hazard.

[0006] As yet another example, low power variable optics (LPVO) can provide lx to 8x magnification. However, such devices are also subject to downtime during magnification changes. In particular, LPVO devices typically require a user to release the weapon with one hand to change magnification, meaning the target must be reacquired after the magnification change is complete.

[0007] Other examples include optics that employ variable focal length lenses, which have poorer light transmission than standard lenses. Furthermore, variable focal length lenses are difficult to manufacture to a sufficient size. Consequently, optics using variable focal length lenses can have poor image brightness and an inadequate eye box.

[0008] The prior systems suffer from drawbacks that decrease overall system effectiveness while increasing complexity, which can lead to user error when manipulating the system. Thus, the need exists for a weapon sight that is easy-to-use, ergonomic, quiet, and capable of rapidly changing without downtime between different magnification levels.SUMMARY OF THE INVENTION

[0009] It is one aspect of some embodiments of the present invention to provide a dual power optic assembly for use with a firearm. The contemplated dual power optic assembly comprises an actuator switch operatively coupled with a drive motor configured to be attached to a side portion of the firearm. In some embodiments, a motor controller or microcontroller is operatively disposed between the actuator switch and the drive motor. The dual power optic assembly of this embodiment includes an erector drive subassembly. The erector drive subassembly includes a drive motor coupled with a pinion gear and a driven gear configured to be actuated by the pinion gear. A cam tube is coupled with the driven gear, wherein the cam tube and the driven gear are configured to rotate in unison. A first erector lens and a second erector lens are disposed within a pivot tube that is at least partially disposed within the interior of the cam tube. According to many embodiments, the cam tube does not directly contact the pivot tube, and a set of ball bearings is disposed between the cam tube and the pivot tube.

[0010] In operation, user activation of the actuator switch causes the first erector lens and the second erector lens to move between a first preconfigured position and a second preconfigured position within the pivot tube. In many embodiments, the first preconfigured position is associated with a first magnification level of the dual pow er optic assembly, and the second preconfigured position is associated with a second magnification level of the dual pow er optic assembly, wherein the second magnification level is greater than the first magnification level. In some embodiments, the actuator switch is configured to transition the erector lenses from the first preconfigured position to the second preconfigured position and vice-versa upon a single actuation event (e.g., a button tap or press / release, a voice command, an eye blink, a pupil shift, the receipt of an external signal, etc.). Conversely, most, if not all, current dynamic focusing systems for scopes, cameras, etc., require a continuous actuation signal or actuator button pressure. Indeed, some embodiments of the present invention are configured to move to the first preconfigured position upon a single actuation command (e.g., one button tap), to a second preconfigured position (e.g., tw o button taps) upon a double actuation command, etc.

[0011] The dual power optic assembly of one embodiment is a magnified optic capable of powered rapid switching between two or more magnification modes (e.g., lx and 6x, lx and 8x, 2x and 8x, etc.). The assembly of one embodiment can switch between magnification modes between about 0-1000 milliseconds (ms), preferably between about 100-300 ms, and more preferably in about 200 ms. In some embodiments, the dual power optic assembly can be configured to have an effective range that matches that of the host assault rifle. In many embodiments, the dual power optic system is actuated by an internal electric motor, which can be battery powered. One of ordinary skill in the art w ill appreciate that the contemplated battery may be rechargeable or solar powered. Further, the dual power optic assembly can include an actuation control button that can be located on the firearm and within reach of the support hand. In some embodiments, actuation control is performed remotely, wherein the dual power optic assembly includes a communication module that can receive various types of signals via WiFi, Bluetooth, radio, etc. This capability would also allow users to selectively modify lens arrangements, magnification settings, etc.

[0012] According to another aspect of some embodiments, the dual power optic assembly can have a single viewing window configured for one head position and / or cheek weld. In some embodiments, the dual power optic assembly can further comprise an illuminated reticle for a first magnification (e.g., lx magnification), wherein the source of illumination can be configured to automatically turn off, dim, or alter in some other way when the dual power opticsystem is transitioned to a second, higher magnification mode (e.g., 6x magnification). The dual power optic assembly can further include a ranging reticle (e.g., bullet drop compensation or "BDC") associated with the second, higher magnification mode. One of ordinary skill in the art will appreciate that this functionality can be incorporated into existing optical systems that employ illuminated reticles that obstruct a target at higher magnifications. Accordingly, it is another aspect of embodiments of the present invention to provide a reticle system having an illumination device associated with a lens position or drive motor control system, wherein the position of a lens or lenses dictates the character / form of the illumination.

[0013] According to another aspect of many embodiments, the dual power optic assembly can be configured for a single grip. In other words, the dual power optic assembly does not require the user to change the weapon position based on range or adjust the magnification of the dual power optic assembly. An advantage of the dual power optic assembly is that it is configured to minimize the user fidgeting with adjustments or creating extraneous motions.

[0084] Fig. 1-12 show a dual power optic assembly 100 of one embodiment of the present invention interconnected to a firearm 102. The assembly 100 includes an actuator switch 105 within reach of the support hand of a user. In some embodiments, a second actuator switch 107 is included and positioned within reach of the firing hand. Accordingly, the assembly 100 can be configured for one head and grip position.

[0085] Fig. 2 and 3 are perspective views of one embodiment of assembly 100 that comprises an ocular subassembly 110, an erector drive subassembly 120. a drive motor 125. housing 130. an objective subassembly 140, a mounting base 150, the actuator switch 105 coupled with an actuator connector 108, a battery contained within battery compartment 143, battery door 144, and one or more zero adjustment dials 142. According to some embodiments, actuator connector 108 is configured to detachably engage with a cable of the actuator switch 105. such that actuator switch 105 can be replaced. Furthermore, in some embodiments, the drive motor 125 is disposed in erector drive subassembly 120. In other embodiments, the drive motor 125 is disposed in ocular subassembly 110, or some other section of the assembly 100. In still other embodiments, the drive motor 125 can be disposed in a housing separate from the assembly 100.

[0086] As shown in Figs. 4 and 5, the assembly 100 of one embodiment of the present invention. Here, the assembly 100 comprises an ocular lens 112, a reticle 113, a reticle illuminator 114, a first erector lens 122, a second erector lens 124, a fixed lens 131, a field lens 133, a zero adjustment screw 132, an objective lens 141, and a controller printed circuit board assembly (PCBA) 135. To change magnifications, the first erector lens 122 and the second erector lens 124 are configured to transition between two or more preconfigured positions along the length of an erector cam tube 128. Dry film may be used on the inner surface of the cam tube and / or outer surface of lens holders to reduce friction, which enhances system efficiency.

[0087] The ocular subassembly 110 is located at a proximal end of the assembly 100 (i.e., the end closest to the user’s eye), and an objective subassembly is positioned at a distal end of the assembly 100 (i.e., the end furthest away from the user's eye). In many embodiments, a distal end of the ocular subassembly 110 can be coupled with a proximal end of the erector drive subassembly 120, which can be entirely or partially disposed within the housing 130. In some embodiments, a distal end of the erector drive subassembly 120 is coupled with the objective subassembly 140. In some embodiments, the assembly 100 is configured to be secured to a firearm via a mounting base 150 and / or a mount claw coupled with the housing 130.

[0088] The first erector lens 122 and the second erector lens 124 are in preconfigured position A’ and positioned at a first predetermined distance relative to each other, which is associated with a first predetermined magnification (e.g., lx magnification) Further, in preconfigured position A’, first erector lens 122 and second erector lens 124 are positioned at a first predetermined location along the length of the erector cam tube 128. Preconfigured position B’ is associated with a second predetermined magnification (e.g., 6x magnification). As shown in dashed outline, in preconfigured position B’, the first erector lens 122 and the second erector lens 124 are positioned at a second predetermined distance relative to each other. Further, in preconfigured position B', the first erector lens 122 and the second erector lens 124 are positioned at a second predetermined location along the length of the erector cam tube 128. In operation, user actuation of the actuator switch will generate one or more signals received by the controller PCBA 135, which activates the drive motor 125 and causes the first erector lens 122 and the second erector lens 124 to rapidly transition between the two preconfigured positions, A’ and B’, along the length of the erector cam tube 128 to effect a near-instantaneous change in magnification.

[0089] Figs. 6 and 7 show the erector drive subassembly 120 of one embodiment of the present invention. In this example, the erector drive subassembly 120 includes the cam tube 128, a pinion gear 127, the drive motor 125, and motor mount 126. The drive motor 125 is configured to actuate cam tube 128, causing the erector lenses to transition between preconfigured positions (as show n in Fig. 4), which will be described in further detail below'.

[0090] Fig. 8 show s components of an erector drive subassembly of one embodiment of the present invention. The reticle 113 is provided at the proximal end of the erector drive subassembly and is coupled with a reticle holder 115. Moving along longitudinal axis, L’, in a distal direction, a pivot tube 134 is located at the distal end of reticle 113. According to one aspect of many embodiments, the pivot tube 134 includes a longitudinal slot configured to receive one or more erector lens cam followers 153, 154. Next, the first erector lens 122 is provided and coupled with a first erector lens holder 152 that accommodates the first erector lens cam follower 153. Similarly, a second erector lens 124 is provided and coupled with a second erector lens holder 155 that accommodates the second erector lens cam follower 154. Thus, the first erector lens 122 (along with the first erector lens holder 152 and the first erector lens cam follower 153), and the second erector lens 124 (along with the second erector lens holder 155 and the second erector lens cam follower 154) are operatively configured to travel within an interior of pivot tube 134, along longitudinal axis, L’.

[0091] Referring still to Fig. 8, a pivot socket 161 and afirst ball bearing 138 are provided and coupled to a driven gear 137 at a proximal end of the pivot tube. Moving further along longitudinal axis, L’, a spacer is provided. Next, a second ball bearings 148 are provided a proximal end and a distal end of the cam tube 128. Here, the cam tube 128 includes a slotted track 129 configured to receive the one or more erector lens cam followers 153, 154. In some embodiments, the slotted track 129 can comprise a first track portion that extends diagonally across the surface of the cam tube 128, and a second track portion disposed at the end of the slotted track 129. In some embodiments, the second track portion can be substantially parallel with an end of the cam tube and, as such, is configured to prevent the erector lenses from moving under recoil of the firearm w'hen the erector lenses are at either of their two end positions. In some alternative embodiments, one or more mechanical brakes can be utilized to prevent movement of the erector lenses under recoil of the firearm. Next, a cam retainer 164, a fixed lens 131, and a zero adjustment bearing 165 are provided at the distal end of the erector drive subassembly. It should be noted that the structures described with respect to Fig. 8 are meant to be illustrative of an example embodiment of an erector drive subassembly. Those ofordinary' skill in the art will recognize that the omission and / or combination of certain componentry to perform the same function, to achieve the same result in the same way, are fully within the scope of the present invention.

[0092] Fig. 9 is a cross-sectional view of the erector drive subassembly for use with an assembly 120 that comprises a zeroing mechanism. According to one aspect of many embodiments of the present invention, the connection between the driven gear 137 and the cam tube 128 allows the pivot tube 134 to pivot by virtue of a spherical interface 139 located at the proximal end of the pivot tube 134. A distal end of the pivot tube terminates adjacent to one or more zero adjustment screw contact points 123, wherein one or more corresponding zero adjustment screws 132 (shown in Fig. 8) are configured to interface. Selective adjustment of the pivot tube 134 is accomplished by rotation of corresponding zero adjustment dials 142, which forces the zero adjustment screws 132 against screw contact points 123 and rotates pivot tube 134 about point P.

[0093] As shown in Figs. 10A and 10B, rotatable engagement between the proximal end of the pivot tube 134 and the driven gear 137 is provided by the spherical interface 139, which is operatively engaged within the pivot socket 161 associated with the driven gear through the ball bearing 138. This configuration allows the pivot tube 134 to selectively rotate about point P independent of the driven gear, the upward extreme being shown in Fig. 10A and downward extreme being shown in Fig. 10B. As discussed above, selective lens movement is accomplished by rotation of the cam tube 128 when a pin 176 extending from an inner surface of the driven gear 137 and located into a slot 178 extending from the proximal end of the cam tube interact. That is, driven gear rotation urges the pin 176 against the walls of the slot 178, which rotates the cam tube 128 generally in conjunction with the driven gear 137. The slot 178 allows the pin 176 to maintain operative engagement with the cam tube 128 as the pivot tube 134 is rotated, i.e., selectively tilted, as shown in Figs. 10A and 10B. This configuration ensures the teeth of the pinion gear and the driven gear remain substantially in contact and correctly enmeshed when the pivot tube is rotated. Maintaining gear alignment helps ensure proper rotational control, wherein the lenses are moved by the motor as desired.

[0094] Fig. 10 and 11 show the driven gear 137, supported by the ball bearing 138 mounted internally to the motor mount 126. The driven gear 137 is associated with the cam tube 128, and both rotate in unison when the drive motor 125 is engaged, which rotates the pinion gear 127 and, thus, the driven gear 137. The operation of these components eliminates and / orreplaces a traditional external zoom adjustment ring, along with the seals and the associated friction. That is, manually engaged knobs, for example, are not required. As an added advantage, O-rings traditionally used to accommodate the sealing of such external adjustment mechanisms are no longer required, thereby reducing friction the motor must overcome to drive the system.

[0095] Fig. 11 also illustrates how the motor 125 of some embodiments of the present invention can be a brushless DC electric motor (BLDC). Here, a motor encoder 170 and a cam encoder associated with the driven gear 137 are provided. The cam encoder measures the position of the cam tube 128 to define initial system conditions. The motor encoder on the brushless motor controls the motor movement as it is configured to read the motor’s rotational position within a 360-degree circle. A microcontroller that controls the motor may be provided to assess cam tube 128 rotational position. Because the cam tube 128 cannot physically rotate more than 360 degrees, the output of a single-turn absolute encoder is always valid. Motor revolution count can be determined by multiplying the gear ratio between the cam tube and the motor. Thus, each time the drive motor is activated, the microcontroller reads the cam encoder to determine the starting position and calculates the number of turns required of the motor to reach the desired target position. The cam encoder 174 can be mounted anywhere along the gear train as long as there is some gear ratio between it and the motor encoder 170. Based on this ratio, the position of the two encoders can be compared, and the absolute position of the cam tube 128 can be determined, even if the cam encoder 174 does not directly measure the cam tube position.

[0096] Fig. 12 illustrates how the cam tube 128 of some embodiments of the present invention is supported by the ball bearings 148 such that the cam tube does not contact the pivot tube 134. By contrast, in some known systems, a cam tube bears directly on the pivot tube, with a thrust asher arrangement at either end to retain the component's coaxial arrangement. In some prior art systems, configuring components in this fashion results in relatively high frictional losses. The presence of the ball bearings 148 introduces a low rolling resistance and, therefore, better efficiency.

[0097] Fig. 13 A to 13C show the erector drive subassembly in different stages of operation, in Fig. 13A, the first erector lens 122 and the second erector lens 124 are disposed within pivot tube 134 in the first preconfigured position, which may be associated with a first magnification level (e.g., lx magnification). Fig. 13B shows the cam tube 128 rotated in response to the drivemotor actuating the pinion gear and rotating the cam tube 128 along Arrow A, which advances the first and second erector lenses along the longitudinal axis of the pivot tube 134 towards the second preconfigured position, as indicated by Arrow B. According to one aspect of the present invention, the ball bearings 148 disposed between the cam tube 128 and the pivot tube 134 reduce friction and increase efficiency of the rotational movement of the cam tube 128. Fig. 13C shows the first erector lens 122 and the second erector lens 124 at the second preconfigured position, which may be associated with a second magnification level (e.g., 6x magnification). In many embodiments, the second magnification level can be greater than the first magnification level.

[0098] Many of the embodiments described herein include one or more sets of ball bearings (e.g., ball bearings 138 in Fig. 11). Those of skill in the art, however, will appreciate that other types of bearings can be utilized, such as. for example, plain bearings, roller bearings, needle bearings, air bearings, or any combination or arrangement thereof. Additionally, in some embodiments, the structural members comprise bearing surfaces instead of bearings. According to one aspect of some embodiments, for example, a first structural member (e.g., the cam tube 128) comprises a first bearing surface, and a second structural member (e.g., the pivot tube 134) comprises a second bearing surface that is made of a different material than the first bearing surface, wherein the interaction between the two dissimilar bearing surfaces function similar to a ball bearing.

[0099] Some embodiments of the present invention include a manual override system 180 as shown in Figs. 14A and 14B that allows users to adjust zoom manually. The manual override system 180 may be incorporated into the motor mount 126 and located adjacent to a housing 184 associated with the ocular lens. The manual override system 180 generally includes a shaft 188 having a knob 190 at one and a gear 192 at a second end. As one of ordinary7skill in the art will appreciate, at least one seal 196 may be required to maintain purge gas ithin the assembly and debris and the elements out of the assembly. In operation, the user urges the knob 190 in the direction of Arrow C to separate the gear 192 from the driven gear 137, thereby disengaging the manual override system 180. Pulling the knob 190 in an opposite direction will reengage the driven gear 137 and the gear 192, as shown in Fig. 14B. Disengagement of the manual override may be necessary to reduce rotation resistance associated with the at least one seal 196 that the motor must address.

[0100] Fig. 15 shows features employed by some embodiments of the present invention to control cam tube 128 rotation. More specifically, a brushed motor driven by an H bridge is used instead of the microcontroller and associated BLDC hardware described above to control cam tube rotation. One of ordinary skill in the art will appreciate that such systems would only provide forward / reverse / off control and no speed / position control when the actuator button is pressed. Here, transistor logic directs the motor 125 to disengage when a magnet 197 or other type of actuator interconnected to the driven gear 137 is near one or more limit switches 198.

[0101] Fig. 16 is a cross-sectional side view of an alternate embodiment of an erector drive subassembly 220. In many respects, erector drive assembly 220 includes the same or similar structures and features as erector drive assembly described above. For example, this erector drive subassembly 220 includes a cam tube 228, a cam tube 228, a ball bearing 248 at each end of pivot tube 234, a first erector lens 222. and a second erector lens 224. Here, however, the erector drive subassembly 220 does not include a drive motor coupled with a pinion gear that actuates a driven gear. Instead, a motor consisting of a stator 227 mounted to the pivot tube 234 and a rotor 237 mounted to the cam tube 228 are provided.

[0102] Figs. 17A and 17B show yet another embodiment of the erector drive subassembly 320 that employs a lens flip linkage mechanism. In this example, the erector drive subassembly 320 includes two first erector lenses 322A, 322B, associated with a first magnification (e.g., lx magnification) and a second erector lens 324 associated with a second magnification (e.g., 6x magnification) that are configured to flip up-and-down along Arrow D. When the erector lenses 322A and 322B are deployed in an upright position (e.g., aligned with the longitudinal axis of the pivot tube), the second erector lens 324 is in a down position. Conversely, when erector lenses 322A, 322B are in a down position, the erector lens 324 is in an upright position (e.g., aligned w ith the longitudinal axis of the pivot tube after being rotated in the direction of Arrow7E). In some embodiments, the erector lens 324 comprises tw o lenses in a single housing. In other embodiments, the erector lens 324 comprises a single lens.

[0103] Figs. 18A and 18B shows another embodiment of an erector drive subassembly 420 that includes a mechanism for rotating lenses in the X-Z plane. This embodiment includes a substantially planar mount 421 accommodating erector lenses 422A, 422B, and 424. The mount 421 rotates generally along the direction of Arrow F in the X-Z plane into two or more predetermined positions associated with a magnification level. In Fig. 18A the mount is in a first predetermined position and the erector lenses 422A and 422B are aligned with thelongitudinal axis of the pivot tube, wherein the first predetermined position is associated with a first magnification (e.g., lx magnification).
