    Abstract [0037] Embodiments herein relate to the field of firearms, and, morespecifically, to laser sights for firearms, particularly laser sights having multiple laserdiodes. Various embodiments of the disclosed systems may include two or morelasers in a single unit, and may not only be relatively less expensive relative to unitswith two separate lasers and housings, but they may also be easier to calibrate anduse. For example, in various embodiments, the system may include two or morelasers that may be adjusted for windage and elevation (e.g., calibrated)simultaneously. Thus, in various embodiments, one or more infrared diodes may becalibrated automatically when a corresponding visible light diode is calibrated, and vice versa.

    专利说明:

    [3] [0003] Lasers have been used in many firearms applications as tools toenhance targeting. For example, one form of firearm sight makes use of a laserplaced on a handgun or a rifle and aligned to emit a beam parallel to the barrel.Since a laser beam by definition has low divergence, the laser light appears as asmall spot even at long distances. The user places the spot on the desired targetand the barrel of the gun is aligned (but not necessarily allowing for bullet drop ormovement of the target while the bullet travels).
    [4] [0004] Most laser sights use a red laser diode. Others use an infrared diodeto produce a dot invisible to the naked human eye but detectable with night visiondevices. Many sights can be calibrated in order to precisely align them with thebarrel of the firearm. However, it is difficult to calibrate (e.g., “sight”) an infrared laserdue to the need for special infrared vision gear, and the procedure cannot be carriedin daylight. Furthermore, dual red/infrared sights must be sighted twice: once toalign the red laser diode and a second time to align the infrared laser diode.
    [5] [0005] Additional problems with laser sights is that they can render the firearmincompatible with a holster, they can be awkward to use, and activation of the sightcan require grip changes that interfere with quick and effective shooting procedures.
    [6] [0006] Embodiments will be readily understood by the following detaileddescription in conjunction with the accompanying drawings. Embodiments areillustrated by way of example and not by way of limitation in the figures of theaccompanying drawings.

    [10] [0010] Figures 4A, 4B and 4C are ISO views of three different examples of a dual laser component, in accordance with various embodiments.
    [11] [0011] ln the following detailed description, reference is made to theaccompanying drawings which form a part hereof, and in which are shown by way ofillustration embodiments that may be practiced. lt is to be understood that otherembodiments may be utilized and structural or logical changes may be made withoutdeparting from the scope. Therefore, the following detailed description is not to betaken in a limiting sense, and the scope of embodiments is defined by the appendedclaims and their equivalents.
    [12] [0012] Various operations may be described as multiple discrete operations inturn, in a manner that may be helpful in understanding embodiments; however, theorder of description should not be construed to imply that these operations are orderdependent

    [14] [0014] The terms “coupled” and ”“connected,”” along with their derivatives, maybe used. lt should be understood that these terms are not intended as synonyms foreach other. Rather, in particular embodiments, “connected” may be used to indicatethat two or more elements are in direct physical or electrical contact with each other.“Coupled” may mean that two or more elements are in direct physical or electricalcontact. However, “coupled” may also mean that two or more elements are not indirect contact with each other, but yet still cooperate or interact with each other.[0015] For the purposes of the description, a phrase in the form “A/B” or in theform “A and/or B” means (A), (B), or (A and B). For the purposes of the description,a phrase in the form “at least one of A, B, and C” means (A), (B), (C), (A and B), (Aand C), (B and C), or (A, B and C). For the purposes of the description, a phrase inthe form “(A)B” means (B) or (AB) that is, A is an optional element.

    [17] [0017] Embodiments herein provide laser aiming systems that may provide auser with a substantial tactical advantage that may allow a handgun to be employedin a variety of day and night applications. Various embodiments of the disclosedsystems may include two or more lasers in a single unit, and may not only berelatively less expensive relative to units with two separate lasers and housings, butthey may also be easier to calibrate and use. For example, in various embodiments,the system may include two or more lasers that may be adjusted for windage andelevation (e.g., calibrated) simultaneously. Thus, in various embodiments, one ormore infrared diodes may be calibrated automatically when a corresponding visiblelight diode is calibrated, and vice versa.
    [18] [0018] ln various embodiments, the laser system may be a handgun grip-integrated system that may provide both an infrared (IR) laser and a visible lightlaser in a single, small, lightweight, ergonomic system. ln use, either laser type maybe selected with the quick activation of a switch, which may be located on the grip insome examples. ln various embodiments, this switch placement may allow thesystem to easily transition between different lighting conditions and applications, withor without the use of auxiliary night vision goggles, at a moment's notice. Variousembodiments of the system also may provide excellent compatibility with holsters.
    [20] [0020] As shown in Figure 1, in various embodiments, the laser system 100generally may be used with any firearm, such as handgun 102, having a barrel 104and a grip 106, and optionally, a trigger 108. Additionally, although system 100 isdescribed in various examples as being used with a handgun, one of skill in the artwill appreciate that in various embodiments, the device may be used with any devicerequiring precision aiming, including lethal and non-lethal weapons such as:electroshock devices such as tasers, firearms having rubber, beanbag, wax, plastic,or other non-lethal impact rounds, shotguns, rocket launchers, cannons, automaticand semi-automatic weapons, crossbows, paintball guns, and non-lethal personalsidearms for chemical agents such as mace, tear gas, pepper spray, andoffensive odor canisters.
    [21] [0021] As described in greater detail below, in some embodiments, system100 may be configured as an integral part of a grip 106 of a handgun 102, such asfor use with handguns 102 that have one or more removable grip panels 110. lnother embodiments, system 100 may be configured to wrap around the front and/orrear of grip 106, for instance for use with handguns 102 that do not have removableor replaceable grip panels. As illustrated in Figure 1, in various embodiments, lasercomponent 114 may include a single housing for two or more |asers 116, forinstance, one or more visible spectrum |asers 116a and one or more infrared spectrum lasers 116b, both of which may be configured for use as laser sights forhandgun 102.
    [22] [0022] ln various embodiments, laser system 100 may also include a masterswitch 120 for powering system 100 off and on, one or more activation switches 118configured to activate one or more of the lasers 116, and a mode switch (not shown)configured to control which laser 116a, 116b is activated by activation switch 120,and therefore which laser 116 is used for sighting: the visible spectrum laser 116a orthe infrared spectrum laser 116b. Although two lasers are shown in thisembodiment, one of skill in the art will appreciate that systems for use in accordancewith the present disclosure may be equipped with three, four, or even more laserdiodes.
    [23] [0023] As described below in greater detail, in various embodiments, the twoor more lasers 116 may be substantially pre-calibrated with respect to each other.Thus, in various embodiments, both (or all) lasers 116 may be calibratedsimultaneously (e.g., aligned for windage and elevation) with respect to barrel 104 ofhandgun 102 by means of windage and elevation screws. ln various embodiments,because the two (or more) lasers 116 are mounted together in a single lasercomponent 114, only one of the lasers 116 needs to be calibrated (sighted oraligned) with respect to barrel 104; calibration of one laser 116 automaticallycalibrates the other laser(s). Thus, in various embodiments, infrared spectrum laser116b may be easily calibrated without the use of night vision goggles simply bycalibrating visible spectrum laser 116a.
    [24] [0024] ln various embodiments, activation switch 118, which may be locatedadjacent to trigger 108, and which may be activated by pressure from a user's handwhen preparing to fire firearm 102, may activate a selected laser 116, allowing theuser to precisely aim firearm 102 at a desired target. Thus, in various embodiments,laser 116 may be activated automatically by a user when his or her grip tightens inpreparation for firing, and no extraneous movements are required for activation thatmight interfere with the grip or firing stance.
    [25] [0025] Figures 2A and 2B are right (Figure 2A) and left (Figure 2B) sideviews of an exemplary laser aiming system configured for use with an exemplaryhandgun, in accordance with various embodiments. As illustrated in Figures 2A and2B, in various embodiments, system 200 may include a laser component 214 havinga single housing for two or more lasers (not shown) that may be simultaneously calibrated for windage and elevation with respect to barrel 204 of handgun 202 asdescribed above with reference to Figure 1. ln various embodiments, system 200also may include a master switch 220 for powering system 200 off and on, one ormore activation switches 218 configured to activate one or more of the |asers 216,and a mode switch 222 configured to control which laser 216a, 216b is activated byactivation switch 220. Although a particular embodiment of master switch 220 isillustrated in Figure 2A, in various embodiments, master switch 220 may take theform of any type of manually operable electromechanical switch capable ofcontrolling power to system 200. Similarly, although master switch 220 is illustratedas being located on the right side ofgrip 206, one of skill in the art will appreciatethat it may be located in any position on handgun 202 that allows ease of use withoutinterference with operation of handgun 202.
    [26] [0026] Additionally, in the illustrated embodiment, laser component 214 is asingle component that may house both a visible light laser source, such as a red orgreen laser diode, and an infrared laser source, such as an infrared diode. Suchlaser sources are discussed in greater detail below. Although laser component 214is illustrated as being a dual-aperture component located adjacent barrel 204 on theright side of handgun 202, one of skill in the art will appreciate that in otherembodiments it may be located in any position that allows the beams from lasercomponent 214 to be directed in a direction generally parallel with barrel 204 (see.e.g., beam 324 in Figure 3. which is described in more detail below).
    [27] [0027] Additionally, in various embodiments, mode switch 222 also may takethe form of any type of manually operable electromechanical switch capable ofswitching operation of system 200 from visible light mode (e.g., red or green laser) toinfrared mode and vice versa, or between different colors of laser (e.g., between redand green |asers). Although mode switch 222 is illustrated as being located on theleft side of grip 206, in various embodiments, it may be located in any position onhandgun 202 that allows ease of use without interference with operation of thehandgun. ln some embodiments, for example, when located on the side of handgun202, mode switch 222 may be operated with the non-dominant hand of the user, forinstance, the hand not holding grip 206. ln other embodiments, mode switch 222may be located adjacent trigger 208, so that it may be activated by the trigger handof the user.
    [28] [0028] ln various embodiments, activation switch 218 may take the form ofany type of switch capable of activating system 200 to illuminate one or more lasersin laser component 214, and in various embodiments, activation switch 218 may belocated adjacent to trigger 208 such that normal pressure from the gripping (e.g.,trigger) hand of the user may activate system 200 and illuminate a laser beam. lnvarious embodiments, the activation method of system 200 may be designed tointegrate smoothly into the user's normal shooting technique such that the process ofquickly and effectively engaging a threat is not disrupted or degraded. ln variousembodiments, activation switch 218 may conform to the user's natural grip, whichdoes not have to break in any way. ln fact, in various embodiments, the gripergonomics may perform to the point that when the user's grip tightens to take ashot, the desired laser beam activates. ln various embodiments, two or moreactivation may be provided that may be spaced apart on either side of grip 206, suchthat system 200 may be activated by pressure on grip 208 from either a right-handedor left-handed user. Particular embodiments of system 200 are designed for usewith tactical gloves, and are MILSPEC 810G certified.
    [29] [0029] ln some embodiments, some handguns, such as the M9 and M11, maybe compatible with an over-mold-type system, such as those illustrated in Figures 1and 2, in which system components may be integrated directly into one or more grippanels. Other handguns, such as those with polymer frames, may not havereplaceable grip panels. Thus, in various embodiments, handguns such as theSpringfield XD and the Glock 17 may be compatible with a grip wraparound-typeversion of the laser aiming system. ln various embodiments, both types of systemsmay incorporate an activation switch adjacent to the trigger, holster compatibility,and overall excellent ergonomic performance.
    [30] [0030] Figures 3A-3D illustrate state diagrams of a laser aiming system 300having a master switch 320, and illustrates one example of how master switch 320,mode switch 322, and activation switch 318 may be adapted to work in concert tocontrol operation of system 300. As shown in Figure 3A, in some embodiments,when mode switch 322 is set to “red,” master switch 320 is set to “on,” and activationswitch is depressed, red visible laser 316a may be activated. Conversely, as shownin Figure 3B, in some embodiments, when mode switch 322 is set to “IR,” masterswitch 320 is set to “on,” and activation switch is depressed, infrared laser 316b maybe activated. As shown in Figure 3C, in some embodiments, when mode switch 322 is set to “red,” master switch 320 is set to “off,” and activation switch is depressed,no laser may be activated. Similarly, as shown in Figure 3D, in variousembodiments, when mode switch 322 is set to “|R,” master switch 320 is set to “off,”and activation switch is depressed, no laser may be activated.
    [31] [0031] As discussed above, in various embodiments, the laser componentmay house at least both a visible spectrum laser source, such as a red or greenlaser diode, and an infrared spectrum laser source, such as an infrared diode.lnfrared lasers are invisible to the human eye, and in some embodiments may beconfigured for use with night vision goggles, which may be used to visualize infraredlasers during aiming and illumination procedures, for example. Visible lasers mayinclude, in various embodiments, red and green laser beams, and generally arevisible to the human eye. Generally, green lasers are much more visible than redlasers, but may be moderately larger in size. Green lasers also may benefit from theuse of additional technology, for instance in order to achieve military acceptableenvironmental temperature range performance. Thus, in particular embodiments,the laser component may house at least both a red laser and an infrared laser. lnspecific, non-limiting examples, the wavelength of a red diode for use in accordancewith the present disclosure may be 635 nm, and the wavelength of an infrared diodefor use in accordance with the present disclosure may be 850 nm. ln additionalspecific, non-limiting examples, the diode power of a red diode configured for use inaccordance with the present disclosure may be 5mW/Class 1, and the diode powerof an infrared diode configured for use with the present disclosure may be5mW/Class 1. ln further specific, non-limiting examples, the divergence of a reddiode configured for use with the present disclosure may be 0.75 mrad x 0.57 mrad,while the divergence of an infrared diode configured for use with the presentdisclosure may be 0.75 mrad x 0.57 mrad.
    [32] [0032] Figures 4A-4C show three examples of a laser module 426a, 426b,426c that may be housed inside the laser component, and that may include visiblelaser diode 428a, 428b, 428c and infrared laser diode 430a, 430b, 430c. ln variousembodiments, the two laser diodes 428a, 428b, 428c and 430a, 430b, 430c may bejoined, in some embodiments, by a coupler or mounting member 432a, 432b, 432c,which may take any of a variety of forms, such as an H-shaped connector 432a or anL-shaped or stepped connector 432b, 432c. ln various embodiments, the two laserdiodes 428, 430 may be aligned with one another such that they produce overlapping laser beams at a predetermined distance when co-activated. ln variousembodiments, the two laser diodes 428, 430 also may be calibrated such that thelaser beams they produce may be aligned with a projectile passing through thebarrel, for instance at a predetermined distance, such as 25 feet, 50 feet, or 25yards. ln some embodiments, because the two laser diodes 428, 430, are coupledby mounting member 432, the laser aiming system may be further calibrated forwindage and elevation by the user in a single step, for instance by calibrating thevisible spectrum laser for windage and elevation, thereby simultaneously calibratingthe corresponding infrared spectrum laser for windage and elevation.
    [33] [0033] Thus, the systems provided herein provide an advantage overconventional systems having two separate lasers, since in a conventional system,each laser must be separately adjusted for windage and elevation. This may bemore difficult to accomplish with infrared lasers, because they must be calibrated inthe dark using night vision goggles, which presents additional difficulties. However,because the systems disclosed herein use a pair of coupled laser diodes 428, 430,both visible spectrum diode 428 and infrared spectrum diode 430 may be calibratedin a single step with a single pair of windage and elevation screws.
    [34] [0034] ln various embodiments, laser module 426 may include a yieldablemember 434 that may allow coupled laser diodes 428, 430 to be pre-calibrated oraligned with respect to one another by causing yieldable member 434 to yield to adesired degree in a desired direction. For instance, in some embodiments, visiblelaser diode 428 may be held in a fixed position while tension is applied to infraredspectrum laser 430, causing yieldable member 434 to deform to a desired degree.ln some embodiments, this procedure may be performed before laser module 426 isinstalled in the laser component. ln various embodiments, yieldable member 434may be sufficiently yieldable to deform to a desired degree under tension, butsufficiently rigid to then maintain a desired alignment between the lasers oncealigned, even under firing pressures and harsh environmental conditions. ln variousembodiments, yieldable member 434a may be a component of mounting member426a, as illustrated in Figure 4A. ln other embodiments, yieldable member 434 mayform a portion of either of laser diodes 428, 430, or it may couple one of the laserdiodes 428, 430 to mounting member 426, as illustrated in Figures 4B and 4C. lnparticular embodiments, the material and/or diameter of yieldable member 434 maybe configured to achieve a desired degree of yieldability. For example, Figure 4B shows a yieldable member 434b with a larger diameter, and so may be made form asofter or more yieldable material. Conversely, Figure 4C shows a yieldable member434c having a smaller diameter, and so may be formed from a harder or lessyieldable material. ln all of the embodiments described above, once yieldablemember 434 has been deformed, and laser diodes 428, 430 are calibrated withrespect to one another, both laser diodes 428, 430 may be calibrated (or sighted)simultaneously as needed in daylight simply by calibrating (sighting) the visible laserusing conventional daylight procedures.
    [35] [0035] ln various embodiments, the laser diodes, 428, 430 may be offset withrespect to one another, such that one diode may project farther fon/vard and mayserve as a pivot point for purposes of adjusting windage and elevation. For example,in the illustrated embodiment, visible spectrum diode 428a, 428b, 428c may projectfarther than infrared spectrum diode 430, 430b, 430c (or vice versa), and mayinclude a domed or otherwise curved surface 436a, 436b, 436c that may function asa pivot point within the laser component. ln particular embodiments, a tensioningelement, such as a spring 438a, 438b, 438c, may be included in a rear portion of thelaser module that may serve to apply tension to hold curved surface 436a, 436b,436c in position against a corresponding surface or window in the housing of thelaser component. ln use, in particular embodiments, windage and elevation screws(not shown) may be provided at right angles with respect to one another that may beconfigured to move mounting member 432, pivoting laser module 426 on curvedsurface 436 and calibrate both lasers simultaneously. Thus, in variousembodiments, the system may include a very simple three-point calibration systemthat includes only two windage and elevation screws and a single tensioning spring.[0036] Although certain embodiments have been illustrated and describedherein, it will be appreciated by those of ordinary skill in the art that a wide variety ofalternate and/or equivalent embodiments or implementations calculated to achievethe same purposes may be substituted for the embodiments shown and describedwithout departing from the scope. Those with skill in the art will readily appreciatethat embodiments may be implemented in a very wide variety of ways. Thisapplication is intended to cover any adaptations or variations of the embodimentsdiscussed herein. Therefore, it is manifestly intended that embodiments be limited only by the claims and the equivalents thereof.
