DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
5 The following is a detailed description of the structure of the firearm sight rectifier in accordance with the present invention.
More specifically, three different versions of the firearm sight rectifier 10 according to the invention will be described; the basic model 11 of appended Figure 1, and the more versatile, upgraded version 12 of Figures 2 and 3 and another upgraded version (60) which can be secured to the open end of a barrel of a firearm.
Basic model 11 of Figure 1:
Referring to Figure 1 of the appended drawings, the firearm sight rectifier 11 comprises an outer casing 13 having substantially the same specifications as the case of a standard cartridge of given caliber. In this manner, the outer casing 13 of the firearm sight rectifier 11 will fit in the barrel of a firearm of that caliber as would do a standard cartridge. For example, if one wishes to use the rectifier 11 in a 30-06 Spg. rifle, the outer casing 13 must have an outer diameter corresponding to that of a 30-06 Spg. cartridge to fit in the barrel of the rifle.
As illustrated in Figure 1, a rear end 14 of the outer casing 13 is closed and defines a cup 15 similar to that of a standard cartridge. A front end 17 of the outer casing 13 is open to receive a bullet-shaped laser module 18.
The outer casing 13 forms a shell defining an inner cavity 16 to receive a conventional laser module 18, a series of batteries 19 and a rubber button type switch 20 for activating the laser module 18.
The rubber button type switch 20 comprises a depression button 21 where the primer of a standard cartridge is normally located. Depression button 21 is, for example, similar to the depression buttons conventionally used for VCR (Videocassette Recorder) or TV
remote control.
An electrically-insulating O-ring type spacer 22 is placed in the cavity 16 and is interposed between the closed rear end 14 and the series of batteries 19 to prevent the batteries 19 from making unwanted contact with the rubber button switch 21. Then the series of batteries 19 is axially disposed in the inner cavity 16 between the spacer 22 and the laser module 18. The laser module 18 is bullet-shaped and comprises at one end a metal spring 23 to connect the bullet-shaped laser module 18 to one end contact of the proximate battery 19. At the other end 24, the laser module 18 emits a laser beam 25 along the longitudinal, geometrical axis 26 of the outer casing 13; for that purpose the housing of the bullet-shaped laser module 18 comprises, at end 24, a cylindrical hole 57 having, for example, a diameter of ~/e inch which must be sufficient to allow the laser beam 25 to propagate without distortion.
More specifically, three different versions of the firearm sight rectifier 10 according to the invention will be described; the basic model 11 of appended Figure 1, and the more versatile, upgraded version 12 of Figures 2 and 3 and another upgraded version (60) which can be secured to the open end of a barrel of a firearm.
Basic model 11 of Figure 1:
Referring to Figure 1 of the appended drawings, the firearm sight rectifier 11 comprises an outer casing 13 having substantially the same specifications as the case of a standard cartridge of given caliber. In this manner, the outer casing 13 of the firearm sight rectifier 11 will fit in the barrel of a firearm of that caliber as would do a standard cartridge. For example, if one wishes to use the rectifier 11 in a 30-06 Spg. rifle, the outer casing 13 must have an outer diameter corresponding to that of a 30-06 Spg. cartridge to fit in the barrel of the rifle.
As illustrated in Figure 1, a rear end 14 of the outer casing 13 is closed and defines a cup 15 similar to that of a standard cartridge. A front end 17 of the outer casing 13 is open to receive a bullet-shaped laser module 18.
The outer casing 13 forms a shell defining an inner cavity 16 to receive a conventional laser module 18, a series of batteries 19 and a rubber button type switch 20 for activating the laser module 18.
The rubber button type switch 20 comprises a depression button 21 where the primer of a standard cartridge is normally located. Depression button 21 is, for example, similar to the depression buttons conventionally used for VCR (Videocassette Recorder) or TV
remote control.
An electrically-insulating O-ring type spacer 22 is placed in the cavity 16 and is interposed between the closed rear end 14 and the series of batteries 19 to prevent the batteries 19 from making unwanted contact with the rubber button switch 21. Then the series of batteries 19 is axially disposed in the inner cavity 16 between the spacer 22 and the laser module 18. The laser module 18 is bullet-shaped and comprises at one end a metal spring 23 to connect the bullet-shaped laser module 18 to one end contact of the proximate battery 19. At the other end 24, the laser module 18 emits a laser beam 25 along the longitudinal, geometrical axis 26 of the outer casing 13; for that purpose the housing of the bullet-shaped laser module 18 comprises, at end 24, a cylindrical hole 57 having, for example, a diameter of ~/e inch which must be sufficient to allow the laser beam 25 to propagate without distortion.
A laser module such as 18 is available on the market and well known to those of ordinary skill in the art. Accordingly, laser module 18 will not be further described in the present patent specification.
The bullet-shaped laser module 18 is fitted on the open front end 17 of the outer casing 13 in the same manner as a conventional bullet is secured to the core of the case of a cartridge. The bullet-shaped laser module 18 can then be assimilated to an empty bullet. The open front end 17 of the outer casing 13 holding the bullet-shaped laser module 18 can be screwed or "push and turn" locked to the rest of the outer casing 13. The open front end 17 can then be unscrewed or "turned and pulled" to remove the assembly open front end 17 - laser module 18 for replacement of the batteries 19. After replacement of the batteries 19, the open front end 17 along with the bullet-shaped laser module 18 are screwed or "pushed and turned" to replace the assembly open front end 17 - laser module 18 on the rest of the outer casing 13.
Of course, the type of the batteries 19 will be selected in relation to their diameter and thickness to fit inside the casing 13.
In operation, the rectifier 11 is introduced into the barrel of the firearm. When it is released, the firepin hits the depression button 21 to electrically connect the series of batteries 19 to the bullet-shaped laser module 18, and thereby activate this laser module 18. For that purpose, the depression button 21 will obviously be linked to the laser module 18 through a small electric wire or a thin and flexible electrically conductive metal sheet. If the outer casing 13 is made of electrically conductive material, another alternative is to link the depression button 21 to the laser module 18 directly through the electrically conductive material of the outer casing 13.
As soon as the laser module 18 is activated, the laser beam 25 can be used to adjust or rectify the rear and front sights or the telescopic sight of the firearm. For that purpose, the laser beam 25 is projected onto a surface (for example a conventional target) to form a light spot on this surface, and the rear and front sights or the telescopic sight of the firearm is(are) adjusted or rectified to home on to this luminous spot. To obtain additional precision, a ballistic chart can of course be used in combination with the luminous spot to adjust or rectify the rear and front sights or the telescopic sight of the firearm.
More versatile, upgraded version 12 of Figures 2 and 3:
The firearm sight rectifier 12 comprises the universal laser beam producing unit 30 of Figure 2 and the caliber adaptor 50 of Figure 3.
The universal laser beam producing unit 30 comprises an outer casing 31. As illustrated in Figure 2, a rear end 32 of the outer casing 31 is closed while a front end 33 thereof is open to receive a conventional laser module 35.
The outer casing 31 forms a shell defining an inner cavity 34 to receive the laser module 35, a series of batteries 36 and a rubber button type switch 37 for activating the laser module 35.
The bullet-shaped laser module 18 is fitted on the open front end 17 of the outer casing 13 in the same manner as a conventional bullet is secured to the core of the case of a cartridge. The bullet-shaped laser module 18 can then be assimilated to an empty bullet. The open front end 17 of the outer casing 13 holding the bullet-shaped laser module 18 can be screwed or "push and turn" locked to the rest of the outer casing 13. The open front end 17 can then be unscrewed or "turned and pulled" to remove the assembly open front end 17 - laser module 18 for replacement of the batteries 19. After replacement of the batteries 19, the open front end 17 along with the bullet-shaped laser module 18 are screwed or "pushed and turned" to replace the assembly open front end 17 - laser module 18 on the rest of the outer casing 13.
Of course, the type of the batteries 19 will be selected in relation to their diameter and thickness to fit inside the casing 13.
In operation, the rectifier 11 is introduced into the barrel of the firearm. When it is released, the firepin hits the depression button 21 to electrically connect the series of batteries 19 to the bullet-shaped laser module 18, and thereby activate this laser module 18. For that purpose, the depression button 21 will obviously be linked to the laser module 18 through a small electric wire or a thin and flexible electrically conductive metal sheet. If the outer casing 13 is made of electrically conductive material, another alternative is to link the depression button 21 to the laser module 18 directly through the electrically conductive material of the outer casing 13.
As soon as the laser module 18 is activated, the laser beam 25 can be used to adjust or rectify the rear and front sights or the telescopic sight of the firearm. For that purpose, the laser beam 25 is projected onto a surface (for example a conventional target) to form a light spot on this surface, and the rear and front sights or the telescopic sight of the firearm is(are) adjusted or rectified to home on to this luminous spot. To obtain additional precision, a ballistic chart can of course be used in combination with the luminous spot to adjust or rectify the rear and front sights or the telescopic sight of the firearm.
More versatile, upgraded version 12 of Figures 2 and 3:
The firearm sight rectifier 12 comprises the universal laser beam producing unit 30 of Figure 2 and the caliber adaptor 50 of Figure 3.
The universal laser beam producing unit 30 comprises an outer casing 31. As illustrated in Figure 2, a rear end 32 of the outer casing 31 is closed while a front end 33 thereof is open to receive a conventional laser module 35.
The outer casing 31 forms a shell defining an inner cavity 34 to receive the laser module 35, a series of batteries 36 and a rubber button type switch 37 for activating the laser module 35.
The rubber button type switch 37 comprises a depression button 38 where the primer of a standard cartridge is normally located. Depression button 38 is, for example, similar to the depression buttons conventionally used for VCR (Videocassette Recorder) or TV
remote control.
An electrically-insulating O-ring type spacer 39 is placed in the cavity 34 and is interposed between the closed rear end 32 and the series of batteries 36 to prevent the batteries 36 from making unwanted contact with the rubber button switch 37. Then the series of batteries 36 is axially disposed in the inner cavity 34 between the spacer 39 and the laser module 35. The laser module 35 comprises a housing having a cylindrical shape and comprises at one end a metal spring 40 to connect the laser module 35 to one end contact of the proximate battery 36. At the other end 41, the laser module 35 emits a laser beam 42 along the longitudinal, geometrical axis 43 of the outer casing 31.
A laser module such as 35 is available on the market and well known to those of ordinary skill in the art. Accordingly, laser module 35 will not be further described in the present patent specification.
The laser module 35 is fitted and secured in the open front end 33 of the outer casing 31 in accordance with any suitable method known to those of ordinary skill in the art. The open front end 33 of the outer casing 31 holding the laser module 35 can be screwed or "push and turn" locked to the remaining portion of the outer casing 31.
The open front end 33 can then be unscrewed or "turned and pulled" to remove the assembly open front end 33 - laser module 35 from the remaining portion of the outer casing 31 for replacement of the batteries 36. After replacement of the batteries 36, the open front end 33 along with the laser module 35 are screwed or °pushed and turned" to replace the assembly open front end 33 - laser module 35 on the remaining portion of the outer casing 31.
Referring to Figure 3 of the appended drawings, the caliber adaptor 50 is formed of a sleeve 51 having substantially the same specifications as the case of a standard cartridge of given caliber. More specifically, the outer surface 52 of the sleeve 51 has a diameter 10 corresponding to that of a cartridge of said given caliber. The sleeve 51 has a bullet-shaped front end 53 and an open rear end 54 formed with a cup 55 similar to that of a conventional cartridge. In this manner, the caliber adaptor 50 of the firearm sight rectifier 12 will fit in the barrel of a firearm of the same caliber as would do a standard cartridge.
Finally, the sleeve 51 defines an inner cavity 56. The universal laser beam producing unit 30 of Figure 2 is inserted in the inner cavity 56 from the open rear end 54 of the sleeve 51. Experiments have shown that no mechanism for retaining the universal laser beam producing unit 30 in the inner cavity 56 is required. However it is within the scope of the present invention to provide such a mechanism, of any suitable design.
The more versatile, upgraded version 12 of the firearm sight rectifier according to the invention presents an important advantage:
for example, if the customer owns ten (10) different rifles each of them having a different caliber, this customer will not need ten (10) different firearm sight rectifiers. This customer will need only one universal laser beam producing unit 30 with ten (10) caliber adaptors 50 for the ten (10) different calibers, respectively. Obviously, this would be more cost efficient for a consumer having a plurality of rifles of different calibers.
Once the two (2) parts (the universal laser beam producing unit 30 and the caliber adaptor 50) are assembled, this assembly is introduced into the barrel of the firearm. When it is released, the firepin hits the depression button 38 to electrically connect the series of batteries 36 to the laser module 35, and thereby activate this laser module 35. For that purpose, the depression button 38 will obviously be linked to the laser module 35 through a small electric wire or a thin and flexible electrically conductive metal sheet. If the outer casing 31 is made of electrically conductive material, another alternative is to link the depression button 38 to the laser module 35 directly through the electrically conductive material of the outer casing 31.
As soon as the laser module 35 is activated, the laser beam 42 can be used to adjust or rectify the rear and front sights or the telescopic sight of the firearm. Of course, the bullet-shaped front end 53 of the sleeve 51 comprises an axial cylindrical hole 58 having, for example, a diameter of ~/e inch which must be sufficient to allow the laser beam 42 (Figure 2) to propagate without distortion. The laser beam 42 is then projected onto a surface (for example a conventional target) to form a light spot on this surface, and the rear and front sights or the telescopic sight of the firearm is(are) adjusted or rectified to home on to this luminous spot. To obtain additional precision, a ballistic chart can of course be used in combination with the luminous spot to adjust or rectify the rear and front sights or the telescopic sight of the firearm.
It is further within the scope of the present invention to provide means for facilitating removal of the universal laser beam producing unit 30 from the inner cavity 56 of the sleeve 51 of the caliber adaptor 50, in view of facilitating replacement of the caliber adapter.
Either plastic and metal can be used for constructing the firearm sight rectifier according to the present invention. Also, the colour can be selected to enable the consumers to easily identify the firearm sight rectifier either on the shelves of a store or when the rectifier is with the rest of the consumers' munitions.
Sight rectifiier 60 with barrel adaptor shaft 68:
The firearm sight rectifier 60 is shown assembled in Figures 5a and 5b. Figures 4a and 4b show the firearm sight rectifier 60 in a disassembled fashion and without a casing 61. The firearm sight rectifier 60 comprises the universal laser beam producing unit 67 and the shaft adaptor 68.
Figure 4a shows the laser beam producing unit 67 prior to modification for assembly with barrel adaptor shaft 68. The outer casing 61 forms a shell defining an inner cavity 72 to receive the laser module 62, the series of batteries 63, an O-ring 65, a rubber button type switch 64, and a screw cap 71.
remote control.
An electrically-insulating O-ring type spacer 39 is placed in the cavity 34 and is interposed between the closed rear end 32 and the series of batteries 36 to prevent the batteries 36 from making unwanted contact with the rubber button switch 37. Then the series of batteries 36 is axially disposed in the inner cavity 34 between the spacer 39 and the laser module 35. The laser module 35 comprises a housing having a cylindrical shape and comprises at one end a metal spring 40 to connect the laser module 35 to one end contact of the proximate battery 36. At the other end 41, the laser module 35 emits a laser beam 42 along the longitudinal, geometrical axis 43 of the outer casing 31.
A laser module such as 35 is available on the market and well known to those of ordinary skill in the art. Accordingly, laser module 35 will not be further described in the present patent specification.
The laser module 35 is fitted and secured in the open front end 33 of the outer casing 31 in accordance with any suitable method known to those of ordinary skill in the art. The open front end 33 of the outer casing 31 holding the laser module 35 can be screwed or "push and turn" locked to the remaining portion of the outer casing 31.
The open front end 33 can then be unscrewed or "turned and pulled" to remove the assembly open front end 33 - laser module 35 from the remaining portion of the outer casing 31 for replacement of the batteries 36. After replacement of the batteries 36, the open front end 33 along with the laser module 35 are screwed or °pushed and turned" to replace the assembly open front end 33 - laser module 35 on the remaining portion of the outer casing 31.
Referring to Figure 3 of the appended drawings, the caliber adaptor 50 is formed of a sleeve 51 having substantially the same specifications as the case of a standard cartridge of given caliber. More specifically, the outer surface 52 of the sleeve 51 has a diameter 10 corresponding to that of a cartridge of said given caliber. The sleeve 51 has a bullet-shaped front end 53 and an open rear end 54 formed with a cup 55 similar to that of a conventional cartridge. In this manner, the caliber adaptor 50 of the firearm sight rectifier 12 will fit in the barrel of a firearm of the same caliber as would do a standard cartridge.
Finally, the sleeve 51 defines an inner cavity 56. The universal laser beam producing unit 30 of Figure 2 is inserted in the inner cavity 56 from the open rear end 54 of the sleeve 51. Experiments have shown that no mechanism for retaining the universal laser beam producing unit 30 in the inner cavity 56 is required. However it is within the scope of the present invention to provide such a mechanism, of any suitable design.
The more versatile, upgraded version 12 of the firearm sight rectifier according to the invention presents an important advantage:
for example, if the customer owns ten (10) different rifles each of them having a different caliber, this customer will not need ten (10) different firearm sight rectifiers. This customer will need only one universal laser beam producing unit 30 with ten (10) caliber adaptors 50 for the ten (10) different calibers, respectively. Obviously, this would be more cost efficient for a consumer having a plurality of rifles of different calibers.
Once the two (2) parts (the universal laser beam producing unit 30 and the caliber adaptor 50) are assembled, this assembly is introduced into the barrel of the firearm. When it is released, the firepin hits the depression button 38 to electrically connect the series of batteries 36 to the laser module 35, and thereby activate this laser module 35. For that purpose, the depression button 38 will obviously be linked to the laser module 35 through a small electric wire or a thin and flexible electrically conductive metal sheet. If the outer casing 31 is made of electrically conductive material, another alternative is to link the depression button 38 to the laser module 35 directly through the electrically conductive material of the outer casing 31.
As soon as the laser module 35 is activated, the laser beam 42 can be used to adjust or rectify the rear and front sights or the telescopic sight of the firearm. Of course, the bullet-shaped front end 53 of the sleeve 51 comprises an axial cylindrical hole 58 having, for example, a diameter of ~/e inch which must be sufficient to allow the laser beam 42 (Figure 2) to propagate without distortion. The laser beam 42 is then projected onto a surface (for example a conventional target) to form a light spot on this surface, and the rear and front sights or the telescopic sight of the firearm is(are) adjusted or rectified to home on to this luminous spot. To obtain additional precision, a ballistic chart can of course be used in combination with the luminous spot to adjust or rectify the rear and front sights or the telescopic sight of the firearm.
It is further within the scope of the present invention to provide means for facilitating removal of the universal laser beam producing unit 30 from the inner cavity 56 of the sleeve 51 of the caliber adaptor 50, in view of facilitating replacement of the caliber adapter.
Either plastic and metal can be used for constructing the firearm sight rectifier according to the present invention. Also, the colour can be selected to enable the consumers to easily identify the firearm sight rectifier either on the shelves of a store or when the rectifier is with the rest of the consumers' munitions.
Sight rectifiier 60 with barrel adaptor shaft 68:
The firearm sight rectifier 60 is shown assembled in Figures 5a and 5b. Figures 4a and 4b show the firearm sight rectifier 60 in a disassembled fashion and without a casing 61. The firearm sight rectifier 60 comprises the universal laser beam producing unit 67 and the shaft adaptor 68.
Figure 4a shows the laser beam producing unit 67 prior to modification for assembly with barrel adaptor shaft 68. The outer casing 61 forms a shell defining an inner cavity 72 to receive the laser module 62, the series of batteries 63, an O-ring 65, a rubber button type switch 64, and a screw cap 71.
In the modified laser beam producing unit 67 of Figure 4b, the rubber button type switch 64 is removed.
In the assembled fashion (Figure 5b), the firearm sight rectifier 60 comprises a barrel adaptor shaft 68 screwed on to the laser beam producing unit 67. The screw-on end the barrel adaptor shaft 68 is tapered to fit snugly with the screw cap 71 taper. While the O-ring type spacer 65 provides an electrical insulation between the series of batteries 63 and the screw cap 71, the barrel adaptor shaft 68 can be made of conductive material, such as metal, to provide contact between the series of batteries 63 and the conductive screw cap 71. In an embodiment of the invention, the electrical loop is closed by providing a metal spring 73 in contact with the series of batteries 63 and the laser module 62. There is provided an electrical contact between the laser module 62 outer casing 61, which is conductive, and which is in contact with screw cap 71. Therefore, when barrel adaptor shaft 68 is screwed in far enough into screw cap 71, the barrel adaptor shaft 68 contacts the series of batteries 63 thereby closing the electrical loop and providing power to the laser module 62. Barrel adaptor shaft 68 also comprises a taper 76 which enables a snug fit with the barrel thereby ensuring that the barrel adaptor shaft 68 is concentric in the barrel. The laser module 62 then emits a laser beam 66 along the longitudinal geometrical axis 74 of the outer-casing 61.
When assembled, the firearm sight rectifier 60 can be inserted in the barrel of a firearm. The user may then activate or deactivate the laser module 62 by screwing/unscrewing the laser beam producing unit upon barrel adaptor shaft 68. The laser beam 66 can then be used to adjust or rectify the rear and front sights or the telescopic sight of the firearm. Of course, the front end 75 of the outer-casing 61 comprises an arial cylindrical hole (not shown) having, for example, a diameter of 1/8 inch which must be sufficient to allow the laser beam 66 to propagate without distortion. The laser beam 66 is then projected onto a surface (for example, a conventional target) to form a light spot on the surface, and the rear and front sights or the telescopic sight of the firearm is (are) adjusted or rectified to home on to this luminous spot. To obtain additional precision, a ballistic chart can of course be used in combination with the luminous spot to adjust or rectify the rear and front sights or the telescopic sight of the firearm.
In an embodiment of the invention, the barrel adaptor shaft 68 is manufactured to match the size of the firearm bore. Different size barrel adaptor shafts 68 may then be provided in a kit to match different sizes of firearm bores. It is further within the scope of the present invention to provide a means for compensating (69, 70) for the difference in size between the diameter of the barrel adaptor shaft 68 and the firearm bore. This difference in size can be caused by differences in manufacturing specifications or simply by ware of the firearm barrel.
As shown in Figure 6a, in an embodiment of the invention, the barrel adaptor shaft 68 is provided with a spring means 69 which will compensate for any slack between the bore and the barrel adapter shaft 68. As shown in Figure 6b, in another embodiment of the invention, the barrel adaptor shaft 68 is provided with an O-ring 70 which also compensates for any slack between the bore and the barrel adaptor shaft 68.
A person skilled in the art will understand that the embodiments of this unversal laser beam alignment unit are not limited to firearm applications. The universal laser beam alignment unit may be readily be adapted to be used in any industrial application which requires alignment of tubular elements.
Although the present invention has been described hereinabove by way of preferred embodiments thereof, these embodiments can be modified at will, within the scope of the appended claims, without departing from the spirit and nature of the subject 10 invention.
