It should be understood that corresponding reference numerals in the drawings point to similar or corresponding parts and features.
As shown in the diagrams, an optical screen 10 is provided which includes a housing 12, an optics 14, an adjustment system 16 and a lighting system 18. The housing 12 can be selectively attached to a firearm 20 and supports the optics 14, the adjustment system 16 and the illumination system 18.
The optics 14 cooperate with the housing 12 to provide an enlarged image of a target while the setting system 16 adjusts the optics 14 relative to the housing 12 to align the optics 14 relative to the firearm 20. In one embodiment, the optics 14 enlarges a target to a size substantially equal to six times the seen size of the target (ie 6x magnification).
The illumination system 18 cooperates with the optics 14 to illuminate the crosshair pattern 22 (Figs. 40 and 41) to facilitate alignment of the target relative to the optical sight 10 and the firearm 20.
The housing 12 includes a main body 24 attached to an eyepiece 26.
The main body 24 includes a series of threaded holes 28 for use in attaching the housing 12 to the firearm 20 and an inner cavity 30 having a longitudinal axis 32. A first end 34 of the main body 24 includes a substantially circular shape and communicates with the inner the cavity 30 of the housing 12. A second end 36 is located substantially on an opposite side of the main body 24 seen from the first end 34 and similarly comprises a substantially circular cross-section. A tapered hole portion 38 is located between the first end 34 and the second end 36 and includes a stepped surface 40 which defines a profile of the tapered hole portion 38.
The first end 34 of the main body 24 includes an entrance pupil having a larger diameter than an exit pupil of the second end 36. The entrance pupil of the first end 34 determines how much light enters the optical sight 10 and cooperates with the exit pupil to provide it. optical sight 10 with a desired magnification. In one embodiment, the entrance pupil comprises a diameter that is substantially six times larger than the diameter of the exit pupil. Such a design provides the optical sight 10 with a "6x magnification". Although the exit pupil is described as six times smaller than the entrance pupil, the exit pupil can be destroyed to simplify the alignment of the user's eye with the optical sight 10. The first end 34 may include a truncated portion 42 extending a longer distance toward a target than a lower portion 44 to prevent ambient light from causing an aperture light on the optics 14.
The main body 24 supports the adjustment system 16 and may include at least one hole 46 which can receive a portion of the adjustment system 16 therein. The main body 24 may also include an inner arcuate surface 48 which cooperates with the adjustment system 16 to adjust a position of the crosshair pattern 22 relative to a target.
The main body 24 may include a locking member 50 which cooperates with the eyepiece 26 to position the main body 24 relative to the eyepiece 25 and which secures the main body to the eyepiece 26. The locking member 50 may include a projection 52 extending from the main body 24 for interaction with the eyepiece 26.
An annular seal 53 may be provided between the main body 24 and the eyepiece 26 to provide a seal between mating surfaces. For example, the annular seal 53 may be provided in the locking means 50 to provide such a seal. Although the main body is described as comprising a locking member 50 having a projection 52 and an annular seal 53, the main body 24 may additionally and / or alternatively comprise any locking member securing the main body 24 to the eyepiece 26. For example, the locking member 50 may comprise a series of fasteners 54 (Fig. 1) received through the eyepiece 26 and inserted into the main body 24 to position the eyepiece 26 relative to the main body 24 and to secure the eyepiece 26 to the main body 24. If the fasteners 54 are used to secure the eyepiece 26 to the main body 24 , the main body 24 may comprise a series of threaded holes 56 which in a shaped manner receive the fastening elements 54.
The eyepiece 26 is pre-fitted into the main body 24 and can be attached thereto by the locking means 50 as described above. As such, the eyepiece 26 may similarly include threaded holes 58 (not shown) which are pre-adapted to receive the fasteners 54.
The eyepiece 26 includes a longitudinal axis 60 which is coaxial with the longitudinal axis 32 of the main body 24 when the eyepiece 26 is mounted to the main body 24. The eyepiece 26 includes a first end 62 which is attached to the main body 24 by the locking member 50 and a second end located on an opposite side of the eyepiece 26 relative to the first end 62. The first end 62 may include an inner arcuate surface 66 which is aligned with the inner arcuate surface 48 of the main body 24 when the eyepiece is attached to the main body 24. The inner arcuate surface 66 cooperates with the inner arcuate surface 48 of the main body 24 to create a spherical support surface that allows movement of a portion of the optics 14 relative to the housing 12 during adjustment of the optics 14. As will be further described below, movement of a portion of the optics 14 relative to the housing provides 12 setting the crosshair pattern 22 relative to the housing 12 and thus aligning the optical sight 10 relative to the firearm 20. A h eel ring 72 may be located at a distal end of the eyepiece 26, adjacent to the illumination system 18, and may be used to hold a setting mechanism, such as a rotary selector of the illumination system 18. The first end 62 may also include a recess 68 which receives at least a portion of the lighting system 18.
As shown in particular in Figs. 2 and 3, the optics 14 include an objective lens system 74, an image set system 76 and an ocular lens system 78. The objective lens system 74 is a telephoto lens and includes a front group 75 of positive power and a rear group 77 of negative power. The positive group front group 75 is located substantially closest to the first end 34 of the main body 24 and includes a plano-convex double lens 80 which includes a substantially doublet convex lens and a substantially concave convex lens which are attached to an adhesive and a plano-convex single lens 96. The lenses 80 96 can be secured within the first end 34 of the main body 24 by a threaded retaining ring 82 and / or adhesive to position and secure the lenses 80, 96 relative to the main body 24 of the housing 12. The rear group The negative group 77 is located substantially between the positive group front group 75 and the other end 36 of the main body 24 and includes a planar concave single lens 98 and a convex concave double lens 100. Like the positive group front group 75, the single lens 98 and the double lens may 100 of the rear group 77 with negative strength is retained and positioned with the main body 24 of the housing 12 m preferably a threaded holder 83 and / or adhesive.
The imaging system 76 is disposed within the housing 12 substantially between the objective lens system 74 and the ocular lens system 78. The imaging system 76 includes a housing 84, a ceiling prism 86 and a mirror prism 88, which cooperate to form a Pechan pricing unit.
The imaging system 76 cooperates with the objective lens system 74 and the ocular lens system 78 to set an image of a targeted target right relative to the housing 12 and thus the firearm 20. For example, when an image is received at the first end 34 of the main body 24, the image travels along the longitudinal axis 32 of the main body 24 and travels along a beam path of the Pechan prism unit before being seen at the eyepiece 26.
The imaging system 76 also cooperates with the illumination system 18 to provide the overall shape and size of the crosshair pattern 22 shown at an eyepiece lens 90. The pechan price unit is preferably of the type described in US 4,806,007, the disclosure of which is incorporated herein by reference.
The image from the imaging system 76 is received by the ocular lens system 78 which is located closest to the eyepiece 26. The ocular lens system 78 is located substantially on an opposite end of the optical sight 10 relative to the objective lens system 74 and includes the ocular lens 90, which may be a biconvex simple or substantially double-convex lens, and a double-ocular lens 92. Hereinafter, the eyepiece lens 90 is described as a double-convex ocular lens 90. The dual-ocular lens 92 may include a substantially double-convex lens and a substantially double-convex lens with a suitable adhesive. The double convex eyepiece lens 90 and the dual eyepiece lens 92 can be held in a desired position relative to the eyepiece 26 of the housing 12 by a threaded retaining ring 94. Although a threaded retaining ring 94 is described, the double convex eyepiece lens 90 may be and the dual ocular lens 92 is alternatively and / or additionally attached to the eyepiece 26 of the housing 12 by an adhesive.
The optical sight 10 provides a magnification of a target of approximately six times (i.e., 6x magnification) the size of the target seen (i.e., the target seen without the use of the optical sight 10). Increasing the ability of the optical sight 10 to magnify an image of a target improves the ability of the optical sight 10 to magnify distant targets and enables the optical sight 10 to magnify targets at greater distances. In general, such improvements in magnification can be achieved by inserting a lens having a longer focal length. However, an increase in the focal length of the lens increases the overall length of the housing 12 and thus also increases the overall length and size of the optical sight 10.
As described above, a 6x magnification in the present invention is achieved by increasing the lens focal length by using multiple lenses. The interaction between plano-convex single lens 96, plano-concave single-lens 98 and double-lens 100 with the objective lens system 74, the imaging system 76 and the ocular lens system 78 provides the optical sight 10 with the ability to magnify a target six times the seen size of the target.
Expressly, by adding the lenses 96, 98 and 100 to the front group 75 of positive power and the rear group of negative power 77, respectively, it is possible that the optical sight 10 has a 6x magnification without the need for a long and clumsy housing.
As shown in particular in Figs. 4 and 5, the setting system 16 comprises setting units 102, 102 'and biasing units 104, 104'. The adjusting units 102, 102 'cooperate with the biasing units 104, 104' to selectively surface the housing 84 of the imaging system 76 relative to the housing 12. The surface of the housing 84 of the imaging system 76 relative to the housing 12 similarly surfaces the ceiling prism 86 and the mirror prism 88 relative to the housing 12 and thus a position of the hair cross pattern 22 can be set relative to the housing 12. Such settings of the hair cross pattern 22 relative to the housing 12 can be used to guide the hair cross pattern 22 relative to the firearm 20 to take consideration of drift and height.
As shown in Figs. 2 and 5, the optical sight of the present invention includes a first setting unit 102 and a first biasing unit 104 which cooperate to rotate the housing 84 of the image setting system 76 relative to the housing 12 to adjust a height of the crosshair pattern 22. Rotation of the housing 84 causes the crosshair pattern 22 to move in a direction substantially perpendicular to the axes 32, 60 as schematically represented by the arrow "X" in Fig. 2.
As shown in Figs. 3 and 5, the optical screen of the present invention includes a second setting unit 102 'and a second biasing unit 104' which cooperate to move the housing 84 of the image setting system 76 relative to the housing 12. A displacement of the housing 84 of the imaging system 76 relative to the housing 12 in a similar manner to the surface of the crosshair pattern 22 relative to the housing 12. Such a surface of the crosshair pattern 22 relative to the housing 12 may be configured to adjust for drift to properly guide the crosshair pattern relative to the housing 12. and thus the optical sight 10 with the firearm 20. Such a movement of the crosshair pattern 22 is substantially perpendicular to the axes 32, 60 and to the arrow X, as schematically represented by the arrow "Y" in Fig. 3.
Since the first setting unit 102 is substantially identical to the second setting unit 102 'and the first biasing unit 104 is substantially identical to the second biasing unit 104', a detailed description of the second setting unit 102 'and the second biasing unit 104' is omitted.
As shown in Figs. 4 and 5, the first adjusting unit 102 includes a cover 106, an adjusting knob 108, a locking unit 109, a hollow connector 110 and an engaging pin 112. The cover 106 is selectively attachable to the housing 12 and may include a series of threads 114 for shaped engagement with the hollow connector 110. The cover 106 includes an internal volume 116 which substantially receives the counter-adjustment knob 108 and a portion of the hollow connector 110. Although the cover 106 is shown and described by a series of threads 114 which selectively attach the cover 106 to the housing 12 , the lid 10 may include any other feature that allows for selective attachment of the lid 106 to the housing 12, such as, for example, a snap and / or a mechanical fastener.
The adjusting knob 108 is disposed substantially within the inner volume 116 of the cover 106 and includes a plug 118 rotatably attached to the hollow connector 110 and a top cover 120 attached to the plug 118 by a series of fasteners 121 and / or adhesive. The plug 118 includes a threaded extension 122 that is shaped to be inserted into the hollow connector 110 so that rotation of the plug 118 and cylinder head 120 relative to the hollow connector 110 causes the plug 118 to move the cylinder head 120 toward or away from the housing 12, depending on the direction of rotation. of the plug 118 relative to the hollow connector 110.
The locking unit 109 may be located in a radial transverse hole 111 formed through the plug 118 and may comprise a spring 113 which transmits a biasing force to a locking pin 115. with a side wall of the hollow connector 110. A number of axially extending grooves 117 may be peripherally located at spaced intervals around an inner surface of the hollow connector 110 so that upon advancing and retracting the plug 118 by the threads, appreciable physical and / or audible "Click" can be sensed by the operator as the locking pin 115 moves into a nearby groove 117 to facilitate the calibration of the optical sight 10.
The hollow connector 110 is attached to the housing 12 and may include a series of external threads 124 received within a mating threaded hole 126 of the housing 12. Although the hollow connector 110 is described and shown as attached to the housing 12 by a threaded connection, For example, the hollow connector 110 may also be attached to the housing 12 in any suitable manner such as, for example, an epoxy and / or press fit.
The hollow connector 110 includes a center hole 128 having a series of threads 130 that conformally receive the threaded extension 122 of the plug 118. As described above, the plug 118 and the threaded extension 122 rotate relative to the hollow connector when a force is applied. 57U 15 is applied to the adjusting knob 108, the plug 118 and the threaded extension 122 moving toward or away from the housing 12 depending on the engagement between the threaded extension 122 of the plug 118 and the threads 130 of the hollow connector 110. The hollow connector 110 may also include at least a recess 132 formed on its outer surface to receive a seal 134 for sealing a connection between the hollow connector 110 and the housing 12. A similar recess 136 may be formed in the hollow connector 110 near the top cover 120 of the adjusting knob 108 and may likewise receiving a seal 138 to seal a connection between the hollow connection the actuator 110 and the cylinder head 120 of the adjusting knob 108.
The recesses 132, 136 may be integrally formed with the hollow connector 110 and / or machined in an outer surface of the hollow connector 110. The seals 134, 138 may be any suitable seal such as an O-ring. The engaging pin 112 is substantially received within the threaded extension 122 of the plug 118 and includes a mounting portion 140 rotatably received within the threaded extension 122 of the plug 118 and an engaging portion 142 extending from a distal end of the mounting portion 140. The engaging pin 112 is movement with the plug 118. the engaging portion 142 extends from the mounting portion 140 and communicates with the housing 84 of the imaging system 76. The first biasing unit 104 biases the housing 84 of the imaging system 76 in engagement with the engaging portion 142 of the engaging pin 112. The first biasing unit 104 includes a biasing means 144 disposed within a hole 146 of the housing 12. The biasing means 144 may be in communication with the housing 84 of the imaging system 76 or alternatively a cover 148 may be provided substantially between the biasing means 144 and the housing 84 of the imaging system 76. the biasing means 144 a force on the housing 84 of the imaging system 76 which presses the housing 84 into engagement with the engaging portion 142 of the engaging pin 112.
The biasing means 144 may be any suitable spring such as, for example, a coil spring or a linear spring. Since the housing 84 of the imaging system 76 is biased into engagement with the engaging portion 142 of the engaging pin 112, movement of the engaging pin 112 relative to the hollow connector 110 causes the housing 84 of the imaging system 76 to move relative to the housing 12. Position adjustment ball bearings 150 which is substantially between the engaging portion 142 and the lower portion of the hollow connector 110 can dampen such movement of the engaging pin 112 relative to the hollow connector 110. The ball bearings 150 may provide a seal between the engaging portion 142 and the hollow connector 110 and may also move the hinge connector 110. engaging pin 112 when the engaging pin 112 is moved toward or away from the housing 12 to ensure quiet operation of the setting system 16.
With further reference to Figs. 4 and 5, the operation of the setting system will be described in detail. To adjust the height of the crosshair pattern 22 relative to the housing 12, the cover 106 is disengaged from the housing 12. In this design, the cover 106 is secured to the housing 12 by threads. Accordingly, to remove the cover 106 from engagement with the housing 12, a force is applied to the cover 106 to rotate the cover 106 relative to the housing 12. When the cover 106 has been rotated sufficiently relative to the housing 12, the cover 106 can be removed from engagement with the housing 12.
Removing the cover 106 from engagement with the housing 12 exposes the cylinder head 120 of the adjusting knob 108. Exposing the cylinder head 120 allows a force to be applied to the plug 118 of the adjusting knob 108 through the cylinder head 120. A rotational force can be applied substantially to the cylinder head 120 of the adjusting plug 118 to rotate the plug 118 and the threaded extension 122 relative to the hollow connector 110. Rotation of the plug 118 and the threaded extension 122 relative to the hollow connector 110 causes the threaded extension 122 to move relative to the center hole 128 of the hollow connector 110.
As described above, the center hole 128 may include threads 130 that engage the threaded extension 122. Accordingly, when the plug 118, the top cover 120 and the threaded extension 122 have been rotated relative to the housing, the plug 118, the top cover 120 and the threaded extension 122 are caused to move toward or away from the hollow connector 110 due to the engagement between the threads 130 of the center hole 128 and the threaded extension 122 depending on the direction of rotation of the threaded extension 122. the engaging pin 112 is attached to the threaded extension 122 of the adjusting knob 108 and thus, the plug 118, the cylinder head 120 and the threaded extension 122 move when the plug 118, the cylinder head 120 and the threaded extension 122 move relative to the hollow connector 110.
When the force applied to the cover 120 causes the threaded extension 122 to move toward the hollow connector 110, the engaging pin 112 applies a force in a "Z" direction (Fig. 5B) to the housing 84 of the imaging system 76. The application of a force in the Z direction of the housing 84 of the imaging system 76 causes the housing 84 to move toward the bias transmitted to the housing 84 by the first biasing unit 104. Such movement of the housing 84 causes a simultaneous movement of the crosshair pattern 22 in the Z direction relative to the housing. 12 and thus adjusts the height of the crosshair pattern 22 relative to the housing 12.
When a force is applied to the cylinder head 120 in an opposite direction, the threaded extension 122 and the engaging pin 112 move away from the hollow connector 110 in the Z direction. The housing 84 of the imaging system 76 likewise moves in a direction opposite to the Z direction due to the force transmitted to the housing 84 by the biasing means 144 of the first biasing unit 104. As noted above, regardless of the movement of the threaded extension 122 and the engaging pin 112 in a direction substantially opposite to the Z direction, the housing 84 of the imaging system 76 is maintained in communication with the engaging portion 142 of the threaded extension 122 due to the force transmitted to the housing of the imaging system 76 by the biasing means 144 of the first biasing unit. 104.
When the height of the crosshair pattern 22 is adjusted relative to the housing 12, the cover 106 can be placed over the adjusting knob 108 and the hollow connector 110 and reattached to the housing 12. Attaching the cover 106 to the housing 12 prevents further manipulation of the adjusting knob 108 and thus assists in preventing further adjusting the height of the crosshair pattern 22 until the cover 106 is again removed from the housing 12. In other words, the cover 106 prevents inadvertent forces being applied to the top cover 120 causing the plug 118 and the threaded extension 122 to rotate. relative to the hollow connector 110 when height adjustment is not desired. A similar procedure can be performed on the second setting unit 102 'and the second biasing unit 104' to adjust drift by moving the crosshair pattern relative to the housing 12 in a substantially perpendicular direction relative to the Z direction.
As shown in Figs. 1-4B, the illumination system 18 includes a fluorescent fiber 152 attached to the eyepiece 26 of the housing 12. The fluorescent beam 152 is shown wound around an outer surface of the eyepiece 26 and is received substantially within a recess 68 of the eyepiece 26. The fl uorescent fi beam 152 can capture ambient light, illuminate ambient light of a predetermined color (e.g., red or yellow) and conduct ambient light along the length of the fl uorescent fi bar 152. The fl uorescent fi bar 152 is preferably of the type described in US 4,806 007. and US 6,807,742, the disclosures of which are incorporated herein by reference.
The oresorescent fi beam 152 may axially surround the eyepiece 26 of the housing 12 so that the fi bearing 152 surrounds a complete perimeter of the eyepiece 26 (i.e., is wound 360 degrees around an outer surface of the eyepiece 26). The florescent fi bar 152 may include an end disposed within the eyepiece 26 which is hinged substantially to the imaging system 76 to illuminate the crosshair pattern 22. For example, the fl uorescent fi bar 152 may include an end 154 (Fig. 3) extending from the recess 68 of the yoke 68. 26 attached to the mirror prism 88 to illuminate the crosshair pattern 22. In operation, the florescent fi bar 152 receives ambient light and directs the ambient light along a length of the fl uorescent fi bar 152 and substantially toward the end 154. After reaching the end 154 of the fl uorescent fi child 152 is supplied with light to the mirror prism 88 to illuminate the crosshair pattern 22.
The crosshair pattern 22 may be etched on one side of the mirror prism 88 so that light from the fl uorescent fi child 152 illuminates only the etched portion of the mirror prism 88, as described in US 4,806,007. 88 at a portion of the mirror prism 88 which is etched and thus only the transmitted portion is visible at the eyepiece lens 90. The crosshair pattern 22 is thus defiined by the overall shape and size of the etched portion of the mirror prism 88. Since the fluorescent beam 152 collects and directs ambient light along a length of the fluorescent beam 152 toward the end 154, the fluorescent beam 152 may be considered a conduit that captures ambient light and directs the ambient light along a length of the fluorescent light 152.
Winding of the oresorescent fi bar 152 completely around the outer surface of the eyepiece 26 increases the total area of exposed fi bar 152, maximizing the amount of light that can be received by fi bars 152. Furthermore, winding of the fl uorescent fi beam 152 completely decreases around the outer surface of the eyepiece. 26 the overall length of the optical sight 10 because the width of the wound fi bar 152 is reduced while still maintaining a sufficient area of exposed fi ber 152 to collect light. Although winding the oresorescent beam 152 completely around the outer surface of the eyepiece 26 increases the total area of exposed beam 152, a portion of the wound fiber 152 may include a coating 141 (Fig. 4A) to restrict light from collecting by the fiber 152. For example, a coating such as a black mask may be applied to a portion of the wound fi bern 152 on a lower portion of the optical screen 10. The coating prevents light from being collected by fi bern 152 where the mask is applied to limit light collection. to a region that is substantially between the ends of the coating Illumination of the crosshair pattern 22 allows the use of the optical sight 10 in various kinds of ambient conditions. Illumination of the crosshair pattern 22 can be adjusted depending on such ambient conditions. For example, in dark conditions, the crosshair pattern 22 may be illuminated to enable the use of the optical sight at night and / or in dark conditions such as a building. In other circumstances, the crosshair pattern 22 may be illuminated to enable the crosshair pattern to appear in a bright place such as when the optical sight 10 is used in sunlight and / or among other illuminated devices (ie, for example, tractor or brake light in a military combat area). Illumination of the crosshair pattern 22 is usually prescribed by conditions in which the optical sight 10 is used. For example, when the optical screen 10 is used at night, the crosshair pattern 22 can be illuminated only sufficiently so that the user can see the crosshair pattern 22 but not to such an extent that the crosshair pattern is visible at the first end 34 of the housing 12. However, when the optical screen 10 is used in sunny conditions or among other lights, such as, for example, tra fi lights in a military battle area, the crosshair pattern 22 can be illuminated to a greater extent to enable the crosshair pattern 22 to emerge from bright lights and to enable the user to see the crosshair pattern 22 clearly.
Adjustment of the amount of light supplied to the crosshair pattern 22 may be included in the lighting system 18 through a rotary selector or sleeve 156. Although the rotary selector sleeve 156 is described and shown in the drawings as rotatable relative to the housing 12, the rotary selector sleeve 156 may alternatively be slidable. otherwise movable relative to the housing 12 to selectively expose the fl uorescent fi child 152.
The rotary selector 156 may include a body 160 having an aperture 158 formed therethrough and selectively letting ambient light through the rotary selector 156. The body 160 may be formed of a rigid material such as metal and may be rotatably supported relative to the housing 12 by the eyepiece 26 The opening 158 may comprise a cover member 159 which is attached to the rotary selector 156 and which rotates with the rotary selector 156. The cover member 159 may be formed of transparent or translucent material such as, for example, clear plastic. Although the cover member 159 is described as being formed of clear plastic material, the cover member 159 may also be formed of any material that allows light to pass therethrough and be collected by the florescent fi child 152.
Allowing the cover member 159 to rotate with the rotary selector 156 seals the recess 68 and prevents the ingress of dust and other debris into the recess 68.
The prevention of dust and other debris from penetrating the recess 68 likewise prevents such contaminants from encountering the flursor fi bern 152, which prevents damage to the fi bern 152 and maintains an outer surface of the fi bern 152 clean. Further, by attaching the cover member 159 to the rotary selector 10 15 20 25 30 534 970 21 156, the cover member 159 rotates with the rotary selector 156 and is located at a distance from fi bern 152. In this way, dust and / or debris located between the cover member 159 and fi bern 152 is not damaged. an outer surface of the fiber 152 when the rotary selector 156 is moved relative to the children 152. Since the cover member 159 further rotates with the rotary selector 156, it is not possible for dust and / or other debris to collect between an outer surface of the cover member 159 and the rotary selector 156. outer surface of the cover member 159 caused by movement of the rotary selector 156 relative to the cover member 159.
A pair of O-ring seals 161 may be provided between the body 160 and an outer surface of the eyepiece 26 to prevent the ingress of dust and other debris between the cover member 159 and the recess 68 and to make spaces between the body 160 and the body 152. The O-ring seals 161 can provide the recess 68 with an airtight seal that prevents the penetration of såsom uid such as air, nitrogen, and / or water or other debris such as dust or dirt into the recess 68. For example, according to one embodiment, the O-ring seal 161 provides a hermetic seal between the body 160. and the eyepiece 26. The O-ring seals may be formed of an elastomer such as rubber.
An elastomer 169, such as rubber, may usually be arranged around an outer surface of the body 160. The elastomer 169 may comprise a series of projections 163 which facilitate gripping and rotation of the body 160 and consequently the rotary selector 156. The elastomer 169 may be positioned so that the elastomer 169 completely surrounds the cover member 159 and further seals an interface between the body 160 and the cover member 159 to prevent fluid and / or other debris from entering the recess 68 and interfering with the operation of the florescent fi child 152.
As shown in Fig. 4B, another illumination system for use with the optical sight 10 is provided. to identify identical components while identical reference numerals containing 10 15 20 25 30 534 9 Cl 22 letter extensions are used to identify the components that have been modified.
The lighting system 18a may include a body 160a rotatably supported by the eyepiece 26 of the housing 12. The body 160a may include an opening formed therethrough and an elastomer 169a formed over an outer surface of the body 160a. A cover member 159 may be received substantially within the body 160a and may be formed of a transparent or translucent material such as clear plastic. Although the cover member 159a is described as being formed of clear plastic material, the cover member 159a may also be formed of any material that allows light to pass therethrough and be collected by the florescent fi child 152.
A pair of O-ring seals 161 may be disposed substantially between the eyepiece 26 and the body 160a to prevent penetration of såsom uid such as air, nitrogen, and / or water or other debris such as dust or dirt into the recess 68. The O-ring seals 161 may be placed between an inner surface of the cover member 159a and an outer surface of the eyepiece 26, or alternatively may be located between an inner surface of the body 160a and an outer surface of the eyepiece 26. In both configurations, the O-ring seals 161 provide an airtight seal between the cover member 159a and the recess 68 to prevent penetration of fl uid and / or debris into the recess 68. Further, the O-ring seals 161 place the cover member 159a at a distance from the fi member 152 to prevent contact between the cover member 159a and the 15 pins 152.
In both of the above configurations, the width of the aperture 158 may be equivalent to or slightly less than the width of the coating 141 applied to the oresorescent fi bar 152 to allow the rotary selector 156 to substantially prevent or restrict the collection of light by the fl uorescent fi bar 152. For example, if the rotary selector 156 is rotated so that the cover member 159 counteracts the coating 141, the coating 141 may extend over the bars 152 a sufficient distance so that the exposed bars 152 below the cover member 159 are completely coated and therefore can not collect light.
The above feature allows a user to substantially completely prevent light collection by means of the oresorescent beam 152 by placing the cover member 159 over the coated fiber 152. As shown in Fig. 1, the rotary selector 156 is rotatably attached to the eyepiece 26 so that the body 160 of the rotary selector 156 selectively covers the recess 68 of the eyepiece 26. Rotation of the rotary selector 156 relative to the eyepiece 26 causes similar rotation of the opening 158 relative to the eyepiece 26. When the rotary selector 156 is located so that the body 160 substantially covers the recess 68, fl uorescent fi bern 152 located mainly inside the recess 68. In this position ambient light is restricted to enter the recess 68 and is thus limited to be captured by the fl uorescent fi banner 152. In this position only a limited amount of light is supplied to the crosshair pattern 22. The limited amount of light supplied to the crosshair pattern 22 limits the intensity of illumination the crosshair pattern 22.
To again allow ambient light into the recess 68, the rotary selector 156 can be rotated relative to the eyepiece 26 until the aperture 158 exposes the recess 68 and the florescent fi bar 152. In this position, the aperture 158 allows ambient light to travel through the rotary selector 156 and into the fl uorescent fi bar 152. By allowing ambient light into the recess 68 and consequently into the fl uorescent fi beam 152, the rotary selector 156 allows the fl uorescent fi beam 152 to supply ambient light to the crosshair pattern 22 to illuminate the crosshair pattern 22. As noted above, different conditions require different amounts of ambient light to be applied. the crosshair pattern 22. the rotary selector 156 and the aperture 158 cooperate to allow an infinite adjustment of ambient light supplied to the crosshair pattern via the fl uorescent fi bar 152. Since the aperture 158 can be positioned in virtually any position relative to the recess 68 and the fl uorescent fi bar a user can rotate the rotating disk also very small to adjust the amount of ambient light transmitted through the aperture 158 and into the ores uorescent fi bar 152 and can similarly rotate the rotary selector 156 to take into account changing ambient light conditions (i.e., transition from daytime to dusk) to maintain a constant illumination of the crosshair pattern 22. Adjustment of the illumination of the crosshair pattern 22 is practically limitless.
As observed above, the optical sight 10 can be used in dark conditions such as at night and / or in a dark building. Under such conditions, when illumination of the crosshair pattern 22 is required, ambient light is not easily accessible and the florescent fi bar 152 cannot illuminate the hairline pattern 22 even enough when the rotary selector 156 is positioned so that the aperture 158 completely exposes the florescent fiber 152. Under such conditions, it may be necessary to supplement the light transmitted via the fluorescent beam 152 to the crosshair pattern 22.
The lighting system 18 may also include a light emitting diode 162 (LED), an electroluminescent lamp or wire, and / or a tritium lamp 164 to further complement the light supplied to the crosshair pattern 22 via the ores uorescent fi bar 152 (Figs. 6-11). The LED 162 and the tritium lamp 164 are preferably of the type described in US 4,806,007 and US 6,807,742, the disclosure of which is incorporated herein by reference.
The LED 162, the electroluminescent lamp or wire and / or the tritium lamp 164 may be controlled by a control module 165 and may include a power source such as a battery 167.
As shown in particular in Figs. 7-11, different types of lighting devices are intended for use in conjunction with the lighting system 18. The different types of lighting devices may be used in conjunction with the oresorescent fi bar 152 to supply a sufficient amount of light to the crosshair pattern 22 to illuminate the crosshair pattern 22. when insufficient ambient light is applied to the crosshair pattern 22 via the fl uorescent fi bar 152.
As shown in Fig. 7, a lighting device 200 is provided which includes an LED 202 and a black sheath fiber 204. The LED 202 is attached to one end of the black sheath 204 with a suitable fastener and / or an epoxy. The black sheath fiber 204 includes a light channel 206 which receives light from the LED 202 and directs the light along a length of the black sheath 204. Since the black sheath 204 includes darkened walls 208, the light from the LED 202 does not leak. out of the light channel 206 of the black mantle 204 and can thus be transmitted along a length of the black mantle 204 within the light channel 206 without losing significant amounts of light. The illuminator 200 can be used in conjunction with the fluorescent bar 152 to illuminate the crosshair pattern 22. For example, when the optical screen 10 is used in dark conditions so that light from the florescent bar 152 is insufficient to properly illuminate the crosshair pattern. 22, the LED 202 of the illuminator 200 can be lit to provide light to the crosshair pattern 22 via the light channel 206 of the black sheathed child 204. Light from the illuminator 200 can be combined with light from the florescent child 152 to illuminate the crosshair pattern 22.
As shown in Fig. 8a, a lighting device is provided which includes an LED 212, a clear 21ber 214 which may have a diameter of approximately half the diameter of fi bears with black sheath 216 and fl uorescent fi bears 152 which may have a diameter which is approximately half the diameter of fi bern with black sheath 216. The LED 212 is attached to the clear 21 211 by means of a suitable fastener and / or an epoxy. The clear beam 214 and the fluorescent fiber 152 may be joined with UV glue and then inserted into a connector 218. The connector 218 may be a polycarbonate plastic connector having an inner diameter that receives the clear beam 214 and the clear fluorescent fiber 152. 216 may be connected to the ends of both the clear fi child 214 and the fl uorescent fi child 152 by means of a suitable fastener and / or an epoxy. The connector 218 is used to properly position the clear 21 bem 214 and the fl uorescent fi bern 152 relative to the med bern with black sheath 216.
The black sheathed fiber 216 includes a light channel 220 that extends along a length of black sheathed lugs 216 and darkened walls 222.
In operation, light from the LED 212 is transmitted with a length of the clear 21 bern 214 and can be received within the light channel 220 of the med bern with a black sheath 216. The fiber with a black sheath 216 can then direct the light from the LED 212 to the crosshair pattern 22 to illuminate the crosshair pattern 22. However, if there is enough ambient light to allow the fl uorescent fi bern 152 to illuminate the hair cross pattern 22, the fl uorescent fi bern 152 will direct the light through the light channel 220 of the fi bear with black sheath 216 so that 10 15 20 25 30 534 9 Ü 26 the crosshair pattern 22 is illuminated by light from the fl uorescent fiber 152.
A tritium lamp 164 may be attached to the fluorescent lamp 152 and may be used in conjunction with the LED 212 and / or the fluorescent lamp 152, or alternatively may be used independently of the LED 212 and the fluorescent lamp 152 to illuminate the light channel 220.
The black sheathed fiber 216 adjusts the output of the coupled fi brema (i.e., the fl uorescent fi bern 152 and the clear fi bern 214) to either illuminate the crosshair pattern 22 by light from the LED 212 and the clear fi bern 214 or by light from the fl uorescent fi children 152.
As described above, a black mantle 216 illuminates the crosshair pattern 22 by means of either light from the clear 21 211 or fl uorescent fi 152, depending on which light source has a greater brightness. By coupling the clear fiber 214 and the fl uorescent fi bar 152 in the manner previously described, forward illumination of the fl uorescing fi bar 152 eliminates this coupling technique. fl uorescent fi bern 152 and consequently forward illumination of the fl uorescing fiber 152 is eliminated.
Such forward illumination, for example, is undesirable during tactical maneuvers as it may reflect light and identify a user's position.
As shown in Fig. 8B, a lighting device is provided which includes a black jacket 217, a connector 218 and a fluorescent beam 152. The fluorescent 152 may have a diameter approximately equal to the diameter of the black jacket 217 and may be selectively supplying light to the black sheath 217 connector 217. The connector 218 may be a polycarbonate plastic connector comprising an inner diameter that receives the ores uorescent beam 152. The black sheath fiber 217 may be connected to one end of both the fluorescent child 152 and a suitable or fastener. epoxy. The connector 218 may be used to properly position the fluorescent child 152 relative to the black sheathed child 217. The black sheathed fiber 217 comprises a light channel 221 extending along a length of the black sheathed child 217 and darkened walls 223. In operation, light from the ores uorescent fiber 152 may be received within the light channel 221 of the fi bern with black sheath 217. The fiber with the black sheath 217 may then direct the light from fi bern 152 to the hair cross pattern 22 to illuminate the hair cross pattern 22. A tritium lamp 164 may be attached to the fl uorescent fiber 152 and can be used in conjunction with the fl uorescent fi bar 152.
The black sheathed fiber 217 can adjust the output of the coupled fluorescent light bulb 152 and the tritium lamp 164 if each of the light sources provides light to the black sheathed child 217. tritium lamp 164.
As shown in Fig. 9, a lighting device 224 is provided which includes an LED 226, a clear beam 228, a spherical lens 230 and a fiber with a black sheath 232. The LED is attached to the clear beam 228 by means of a suitable fastening element and / or an epoxy so that light from The LED 226 is received by and guided along a length of the clear 22 bern 228. The clear fi bern 228 is connected to the fl uorescent fi bern 152 by means of a connector 234 so that the clear fi bern is arranged next to the fl uorescent fi bern 152. Both the clear fi bern 152. 214 and the florescent fi bearing 152 may have a diameter which is half that of the fi beam with black sheath 232. The diameter of the ball lens 230 may be the same as that of fi bearing with black sheath 232. As described above with respect to the illumination device 210, the coupling device 210 may the device is similarly a machined polycarbonate plastic connector.
The spherical lens 230 may be connected to both the clear bead 228 and the clearing bead 152. the globe lens 230 based on which light source (i.e. ambient towards LED 226) is larger. For example, if ambient light conditions are low so that the LED 226 is larger than ambient light collected by the fluorescent light 152, the spherical lens 230 will conduct light from the LED 226 and the clear light 228 through the spherical lens. 230 rather than directing light from the fl uorescent fi bern 152. The globe lens 230 adjusts light from the clear fi bern 228 and the fl uorescing fi bern 152 depending on the internal reflection of such light within the round globe lens 230.
The spherical lens 230 may be a clear spherical lens with a refractive index substantially greater than 1.9. The spherical lens may have an anti-reflective (AR) coating that may match a range of wavelengths generated by the LED 226 and the fluorescent fiber 152. This anti-reflective coating may eliminate forward illumination of the transverse reflector 152. In addition to being attached to the clear 22 bearing 228 and the fl uorescent fiber 152, the spherical lens 230 may also be attached to the connector 234 and to fi bearing with a black sheath 232. A tritium lamp 164 may be attached to the fl uorescent fi beam 152 and may be used in interaction with the LED 226 and / or the fl uorescent fi bem 152 or alternatively can be used independently of the LED 226 and the fl uorescing fi bern 152 to illuminate the light channel 238.
Depending on the intensity of the light obtained from the clear 22 bern 228 and the fl uorescent fi bern 152, the globe lens 230 conducts light through the globe lens 230 and into the med bears with a black sheath 232. The fiber with a black sheath 232 comprises darkened walls 236 and a light channel 238 which cooperate to conduct light either from the LED 226 or the ores uorescent fiber 152 towards the crosshair pattern 22 to illuminate the crosshair pattern 22.
As shown in Fig. 10, a lighting device 240 is provided which includes an LED 242, a carrier 244 attached to the LED 242 by a fastener and / or an epoxy, a black jacket carrier 246 and a connector 248. The connector 248 splices the fiber 244 The black mantle 246 and the 152 uorescent beam. The diameter of the 152 ores uorescent child 152 may be identical to the black mantle 246.
The LED 242 supplies light to the 24 beam 244, which is guided with the fi beam 244 substantially toward a joint between the fl uorescent fi beam 152 and the 10 beam 10 15 20 25 30 534 970 29 with black sheath 246 within the connector 248. The fluorescent fi beam 152 includes an end which has an inclined surface 250 which receives light from the LED 242 via the fiber 244 and directs the light towards the fiber with a black sheath 246.
Black sheath fiber 246 includes a light channel 252 and darkened walls 254. Light received from the inclined surface 250 of the ores uorescent fi child 152 is passed through the light channel 252 of the black sheathed child 246 and is enclosed within the light channel 252 by the darkened walls 254. with black coat 246.
The inclined surface 250 reflects light from the LED 242 via fi bern 244 to fi bern with black sheath 246 or directs light from the fl uorescent fi bern 152 towards fi bern with black sheath 246. Thus light from the LED is transmitted through the light channel 252 of the black sheath fiber. 246 if light from the LED 242 is greater than light from the fl uorescent fi bar 152. However, if there is enough ambient light to allow the fl uorescing fi bar 152 to illuminate the crosshair pattern 22, the fl uorescent fi beam 152 will conduct light through the light channel 252 of the fiber. with black sheath 246. The light is mainly enclosed within the black sheathed fiber 246 due to the darkened walls 254 of the black sheathed child 246 and is directed towards the hair cross pattern 22 to illuminate the hair cross pattern 22. A tritium lamp 164 may be attached to the fl uorescent and can be used in conjunction with the LED 242 and / or the fl uorescent fi bern 152 or alternatively can be used independently of the LED 242 and the fl uorescera nde fi bern 152 to illuminate the light channel 252.
As shown specifically in Fig. 11A, a lighting device 256 is provided which includes an LED 258, a clear light 260, a black sheathed light 262 including a light channel 263 and a connector 264. The LED 258 is attached to the clear light 260 by means of a fasteners and / or an epoxy and provides the clear fi bern 260 light. The clear 260 bern 260 is spliced with the fl uorescent fi bern 152 by means of the connector 264.

The control system 172 may be connected to the rotating unit 174, which may include a number of positions that allow a user to control the operation of the lighting system 18 by rotating the rotating unit 174 relative to the housing 12. For example, the rotating unit 174 may be moved to a position so that the lighting system 18 supplies light to the crosshair pattern 22 exclusively by the florescent fi bar 152 (i.e. the rotating unit 174 is in an "off" position). Alternatively, the rotating unit 174 may be positioned so that light is applied to the crosshair pattern 22 via the oresorescent beam 152 in conjunction with the LED 162 using any of the embodiments shown in Figs. 7-39. The photosensor and / or photodiode 178 may be used to automatically adjust an amount of light supplied to the crosshair pattern based on ambient conditions in which the optical sight 10 is used, and may additionally be assigned a position on the rotating unit 174. The rotating unit 174 may be positioned in any of the positions to allow a user to choose between the use of the LED 162, the tritium lamp 164, the photosensor and / or the photodiode 178, and the off position, which limits light. applied to the hair cross pattern 22 to only that supplied by the fl uorescent fi child 152.
The battery 167 may be connected to the LED 162 and / or the photosensor and / or the photodiode 178. The battery 167 may supply power to the LED 162 and the photosensor and / or the photodiode 178. If the battery 167 is depleted, the tritium lamp 164 may be used in conjunction with the ores uorescent fi bar 152 to illuminate the crosshair 22. If the battery 167 is weak, the control system 172 may flash a predetermined number of pulses at an initial start of the control system 172 to notify a user of the weak battery ratio.
The control system 172 may also include a band switch 180 which is an on / off switch that allows a user to control the lighting system 18.
The band switch 180 may be in communication with the control system 172 so that when the band switch 180 is in an "on" position, the control system 172 supplies the crosshair pattern 22 with a quantity of light according to the position of the rotating unit 174. For example, if the rotating unit 174 is in a position whereby the LED 162 supplies light to the crosshair pattern 22 in cooperation with the florescent fi bar 152, causes rotation of the band switch 180 to a position that the hair cross pattern 22 is illuminated by means of the LED 162 and the fl uorescent fi bars 152. Depression of the band switch 180. in a off position, the control system 172 turns off and limits the light supplied to the crosshair pattern 22 to only that supplied by the fl uorescent fi bar 152 and the tritium lamp 164.
The rotating unit 174 may comprise a pulse width modulated circuit and / or a resistive system associated with various settings of the rotating unit 174. For example, when the rotating unit 174 is positioned to use pulse width modulated (PWM) control, a PWM signal is applied to the LED. 162 to control the amount of light supplied by the LED 162 between 0% and 100% of a total illumination of the LED 162, depending on the signal supplied by the control system 172 to the LED 162. For example, the rotating unit 174 may comprise five different PWM settings, each setting increasing the PWM signal applied to LED 162 by 20%.
As the rotating unit 174 is rotated between different positions, the intensity of the LED 162 is increased and the illumination of the crosshair pattern 22 is similarly increased.
In addition to using PWM control, the rotating unit 174 may include a resistive, hall effect, reed switch or a magnetic switch system, whereby when the rotating unit 174 is rotated relative to the housing 12, the illumination of the LED 162 is directly modulated and increased / decreased. Controlling the illumination of the LED 162 in this way allows for infinite control of the LED 162 and thus allows the crosshair pattern 22 to be illuminated at virtually any level of illumination.
In Figs. 40 and 41, the crosshair 22 is shown in conjunction with a display 182.
The display 182 may be connected to the control system 172 and may receive instructions from the control system 172. The display 182 may be used in conjunction with any of the foregoing lighting devices 200, 210, 211, 224, 256 and / or any of the lighting devices shown in Figs. 12-39. .
The control system 172 may provide the display 182 with data such as coordinates, range, text messages and / or target identification information so that the user can see the information in the vicinity of the crosshair 22. If the display 182 provides range-related information, the optical sight 10 may also include a range finder (not shown) that provides such information. The display 182 may include an LED, a seven-segment display, or a display of surface crystals (LCD) or any other digital ocular device for use in transmitting an image to the user of the optical sight 10.
The display 182 may be formed by removing a coating from a surface of the prism 88. For example, aluminum may be removed from a surface of the prism to allow light to pass through the prism 88 where the material has been removed - an exposed area. The exposed area may be coated with a dichroic coating to allow most ambient light to pass therethrough while a predetermined color is prevented from passing through.
For example, if the information is displayed on the prism 88 in red, the dichroic coating allows colors having wavelengths different from red to pass through the prism 88 to allow a user to see through the optical sight even in an exposed area. If data is displayed in red, and red is not allowed to pass through the dichroic coating, data can be displayed and viewed in the exposed area.
External inputs or ports may be included in the housing 12 of the optical sight 10. For example, inputs or ports may be USB, firewire, Ethemet, wireless, infrared, rapid read, or any conventional connection to allow a secondary or tertiary piece of equipment to communicate and display various information on the display 182.
