BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is drawn generally to a laser sighting device. More specifically, the present invention is drawn to a laser sighting device that parallels a bore or barrel on multiple sides, projecting a pattern of laser points, lines, or patterns, which aid in sighting in of a target.
2. Description of Related Art
The Percussion Actuated Non-Electric (P.A.N.) Disrupter is a standard weapon that all FBI accredited bomb squad's possess. Existing line-of-sight laser bore sights for the P.A.N. disrupter consist of a single laser secured in a laser sight body that is affixed to the end of the disrupter barrel and secured by mechanical pressure (set screw) or by magnetic attraction. This method obstructs the barrel and causes unnecessary wear and damage to the barrel end.
Existing technology requires the user to physically remove the laser bore sight from the end of the barrel after the target has been acquired, thus creating potential problems. In the high-stress environment of hazardous device render safe operations, the user must remember to remove the laser sight from the barrel before using the P.A.N. disrupter. Failure to remove the laser sight from the barrel before use would require the user to re-approach a hazardous device or cause the destruction of the laser sight if the weapon were to be fired with the sight still in place. Removal of the laser sight from the end of the barrel has the potential to inadvertently move the barrel, thus causing the shot to miss the intended target.
Where the P.A.N. disrupters are mounted on a hazardous duty robot, current technology requires use of lasers, which are offset from the bore, adjacent to the barrel.
SUMMARY OF THE INVENTION
Any time a laser is mounted external to a bore or barrel so as to be utilized as a sighting device, whether the bore or barrel is for a P.A.N. disrupter or any other firearm, tool, or device, the configuration causes a triangulation/parallax effect. The laser does not parallel the bore and therefore can only be accurately sighted in at a single, known distance.
The user of a robot-mounted P.A.N. disrupter does not have the luxury of accurate depth perception during remote operation of the robot. If the distance is closer or farther back from the known sighted distance, then a shot from the P.A.N. disrupter will not be accurate. Additionally, bore obstructing laser sights cannot be used, as they are unable to be removed from a remotely operated robot.
The present invention relates generally to a laser sighting device. More specifically, the present invention is drawn to a laser-sighting device that parallels a bore or barrel on multiple sides, projecting a pattern of laser points, lines, or patterns, which aid in sighting in of a target.
In various exemplary, non-limiting embodiments, the laser sighting device utilizes four laser emitters set in a laser sight body designed to fit on the barrel of the P.A.N. disrupter. The laser sight body slides onto the barrel.
In various exemplary, non-limiting embodiments, each of the laser emitters is secured within a laser emitter aperture formed in the laser sight body so as to initially prevent the laser emitters from making the metal-to-metal contact required to activate the laser emitters. Non-conductive cap screws, which can be used to apply pressure to the laser emitters, are used to secure the laser emitters within the laser emitter apertures. When the cap screws are tightened, pressure is applied to the rear of the laser emitters, the laser emitters are urged deeper into the laser emitter apertures, and metal-to-metal contact is made to activate the laser emitters.
Each of the lasers, when illuminated, projects a beam that is parallel to the bore of the barrel through four equally spaced laser light apertures in the laser sight body. The resulting pattern of projected laser points dependent on the number and arrangement of the laser emitters and the orientation of the laser sight body as mounted on the barrel. By paralleling the bore, the projected laser pattern remains consistent regardless of the range distance. This eliminates the triangulation/parallax effect.
In various exemplary, non-limiting embodiments, prismatic optical enhancements or line generating laser emitters may be used to project a “crosshair” or other pattern.
In certain exemplary, non-limiting embodiments, line generating laser emitters that project an arc may be combined so that four arcs connect and form a circle. It should be appreciated that any geometric shape that can be produced by laser enhancement may be employed. The projected laser beam(s) may be of any color and/or intensity. The number and pattern of laser emitters set into the laser sight body may vary and is not limited to a certain minimum or maximum number.
In various exemplary, non-limiting embodiments, the compression-activated laser emitters are replaced by laser emitters that are controlled by electric, electro-mechanical, or mechanical switches. Laser emitters that have an external power source and/or operational control switches, are also suitable for use in the laser sighting device.
An additional embodiment of the laser sighting device includes the application of high intensity Light Emitting Diodes (LED) in the alternate spaces between the existing laser emitters inside the laser sight body. These LED's may be of all white light in the visible spectrum, of various colors, or in the infrared spectrum. This embodiment allows the target to be visually illuminated thus aiding in the acquisition of proper sight alignment.
Standard Picatinny rails may be machined on the outside of the laser sight body to accommodate additional accessories.
Accordingly, this invention provides a laser sighting device, which projects a pattern that remains consistent regardless of the range distance from the laser sighting device to a target.
This invention separately provides a laser sighting device, which eliminates the triangulation/parallax effect.
This invention separately provides a laser sighting device, which does not obstruct the bore.
This invention separately provides a laser sighting device, which does not need to be removed when the device is fired or discharged.
These and other features and advantages of this invention are described in or are apparent from the following detailed description of the exemplary embodiments.

Turning now to the drawing Figs., FIGS. 1-8 show various views of a first illustrative, non-limiting embodiment of an exemplary laser sighting device according to this invention. As illustrated in FIGS. 1-8, the laser sighting device 100 comprises a laser sight body 110, two or more laser emitters 140, and two or more caps 150.
In various exemplary embodiments, the laser sight body 110 is formed, at least in part, of an electrically conductive material, such as, for example, aluminum, and is formed in a generally cylindrical shape having a bore or barrel aperture 130 formed through the approximate center of the laser sight body 110, along the longitudinal axis of the laser sight body 110. The barrel aperture 130 is formed so as to allow the laser sight body 110 to be positioned around a bore or barrel 160 of a P.A.N. disrupter or any other firearm, weapons system, tool, or device.
The laser sight body 110 includes two or more laser emitter apertures 112 formed in the laser sight body 110. Each laser emitter aperture 112 extends from a threaded portion 114 to a shoulder 116 and a bottom wall 118. Each aperture 112 includes a spring biasing means, such as, for example, an O-ring 117 or a spring washer 119 positioned so as to contact the bottom wall 118.
A laser light aperture 120 extends from the bottom wall 118 of each laser emitter aperture 112 through the laser sight body 110. Each laser light aperture 120 is of a sufficient diameter to allow a laser light beam 148 to be projected through the laser light aperture 120 and out of the laser sight body 110.
In various exemplary, nonlimiting embodiments, each laser emitter 140 is a laser bore sight, such as those available from AimSHOT, Bushnell, Leupold, Hoppes, SightMark, or Tasco. Each laser emitter 140 includes a rim 142 and a body 144. The laser emitter 140 is constructed such that the exterior surface of the rim 142 is electrically isolated from the exterior surface of the body 144. When the exterior surface of the rim 142 is electrically connected to the exterior surface of the body 144, the laser emitter 140 is activated and a laser light beam 148 is projected from the laser emitter 140. While laser bore sights are available in a number of sizes and caliber configurations, laser bore sights created to represent rimfire-type cartridges are preferably used with the present invention.
The overall size and shape of each laser emitter aperture 112 is dictated by the size and shape of the particular laser emitter 140 that is to be utilized with the laser sighting device 100. Thus, each laser emitter aperture 112 is formed such that a laser emitter 140 may be fitted within a laser emitter aperture 112.
When a laser emitter 140 is fitted within a laser emitter aperture 112, the exterior surface of the body 144 contacts the side walls 114 of the laser emitter aperture 112. The forward surface 145 of the body 144 contacts the O-ring 117 (or the spring washer 119) at the bottom wall 118 of the laser emitter aperture 112 and the laser emitter 140 is spring biased such that the rim 142 does not make contact with the shoulder 116 of the laser emitter aperture 112.
A cap 150 is associated with each laser emitter aperture 112. Each cap 150 extends from a top portion 152, to a threaded portion 154, to an end surface 156. Each cap 150 is formed such that the threaded portion 154 can be threaded into the threaded portion 114 of the laser emitter aperture 112.
When a laser emitter 140 is fitted within a laser emitter aperture 112 and a cap 150 is a threadedly connected, via the interaction of the threaded portions 154 and 114, the end surface 156 of the cap 150 makes initial contact with the rear surface 146 of the laser emitter 140. If, after the end surface 156 of the cap 150 makes initial contact with the rear surface 146 of the laser emitter 140, sufficient tightening, rotational torque is applied to the cap 150, and specifically the knob portion 152, the resilience or spring bias of the O-ring 117 (or the spring washer 119) at the bottom wall 118 is overcome sufficient to allow the laser emitter 140 be urged deeper within the laser emitter aperture 112.
When the laser emitter 140 has been urged a sufficient distance within the laser emitter aperture 112, the exterior surface of the rim 142 makes contact with the shoulder 116 of the laser emitter aperture 112. Because the laser sight body 110 is formed of an electrically conductive material, when the exterior surface of the rim 142 makes contact with the shoulder 116, and electrical path is created between the exterior surface of the rim 142 and the exterior surface of the body 144 such that the laser emitter 140 is activated and a laser light beam 148 is produced and projected through the laser light aperture 120.
When sufficient loosening, rotational torque is applied to the cap 150, the resilience or spring bias of the O-ring 117 (or the spring washer 119) applies a force to be forward surface 145 of the laser emitter 140, sufficient to allow the laser emitter 140 be urged out of the laser emitter aperture 112 sufficient to break contact between the exterior surface of the rim 142 and the shoulder 116. When the exterior surface of the rim 142 no longer makes contact with the shoulder 116, the exterior surface of the rim 142 is no longer electrically connected to the exterior surface of the body 144 and the laser light beam 148 is deactivated.
In certain exemplary embodiment, the laser emitters 140 comprise four 0.38 caliber laser bore sights that are inserted into the laser emitter apertures 112 and are suspended inside the laser emitter apertures 112 by rubber ‘O’ rings 117 pushing against the forward surface 145 of the laser emitters 140, preventing electrical contact between the rim 142 and the body 144 of the laser emitters 140. Four non-conductive, plastic caps 150 are tightened to apply pressure to the rear surfaces 146 of the 0.38 caliber laser emitters 140. When the pressure applied to the rear surfaces 146 of the laser emitters 140 is sufficient to overcome the biasing force of the rubber ‘O’ rings 117, the rims 142 contact the shoulders 116 and complete the metal-to-metal contact required to activate the laser emitters 140.
In various exemplary, nonlimiting embodiments, one or more, and preferably two or more, O-ring receiving grooves 132 is/are formed within the barrel aperture 130. Each O-ring receiving grooves 132 is formed so as to receive at least a portion of an O-ring 133, so as to maintain the O-ring 133 in a fixed position relative to the barrel aperture 130. If included, the O-ring(s) 133 help to stabilize the laser sight body 110 around a barrel 160.
In certain exemplary, nonlimiting embodiments, one or more threaded set screw apertures 111 are formed around the laser sight body 110. The threaded set screw apertures 111, if included, extend radially from the center of the laser sight body 110 and are formed so as to accommodate set screws. By tightening the set screws within the threaded set screw apertures 111, the laser sight body 110 is further stabilized around a barrel 160. The setscrews may also be used for alignment adjustment between the laser sight body 110 and the barrel 160.
The laser emitter apertures 112 and associated laser light apertures 120 are generally positioned at equally spaced apart positions around the laser sight body 110. Thus, as illustrated in FIG. 9, when each of the laser emitters 140 is activated, a pattern of laser light beams 148 is projected from the laser sighting device 100, resulting in a pattern of laser points 149 being projected onto a target 170. Because each laser emitter aperture 112 is formed so as to parallel the longitudinal axis of the laser sight body 110 and, in turn, the longitudinal axis of the barrel 160, when the laser emitters 140 are activated, the resulting pattern of laser points projected onto the target are spaced equal distance around the center of the longitudinal axis of the barrel 160.
Because the laser light beams 148 paralleled the bore of the barrel 160, the projected laser pattern remains consistent, regardless of the range distance. This eliminates the triangulation/parallax effect.
It should be appreciated that the number and spacing of the laser emitter apertures 112 is a design choice based upon the number and pattern of generated laser points 149 desired. Thus, the number of laser emitters 140 set into the laser sight body 110 may vary and is not limited to a certain minimum or maximum number. For example, FIG. 11 shows a second illustrative, non-limiting embodiment of an exemplary laser sighting device 200. It should be understood that the laser sighting device 200 comprises components similar or identical to those described above, with respect to FIGS. 1-8. However, as illustrated in FIG. 11, the laser sighting device 200 comprises a laser sight body 210 that is formed so as to accommodate six laser emitters 240 capable of emitting laser light beams 248 through laser light apertures 220. The laser light apertures 220 are spaced equal distance around the laser sight body 210 so that when the laser emitters 140 are activated, a resulting pattern of six, equally spaced laser points is projected onto a target.
In various exemplary embodiments, prismatic optical enhancements may be positioned within the laser light aperture 120 or the laser emitters 140 may comprise line or pattern generating laser emitters 140. By using optical enhancements and/or line or pattern generating laser emitters 140, a “crosshair” or other pattern may be generated and projected onto a target. For example, as illustrated in FIG. 10, line generating laser emitters that project an arc may be combined so that four arcs 149′ are projected onto the target 170. It should be appreciated that any geometric or other shape that can be produced by optical enhancements and/or line or pattern generating laser emitters may be employed.
