DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Referring to FIG. 1 to FIG. 4 of the drawings, a sighting device for a scope 70 of a firearm 80 (such as a rifle) according to a preferred embodiment of the present invention is illustrated, in which the sighting device comprises a first coupling member 10, a second coupling member 20 and a multiple rail arrangement 30. The firearm accessory, such as a scope 70 as an example, is mounted on a firearm 80 having a firearm rail 81. Accordingly, the scope 70 comprises a tubular lens housing 71 that lens are supported therein to define an objective end 711 and a sight (ocular) end 712.

The first coupling member 10 is supported on an upper half portion of the scope 70. The second coupling member 20 is supported on a lower half portion of the scope 70, wherein the second coupling member 20 has an elongated coupling slot 21 formed thereon to detachably engage with the firearm rail 81 of the firearm 80.

Accordingly, when the first and second coupling members 10, 20 are coupled with each other to form an elongated tubular member, an elongated receiving cavity is formed within the first and second coupling members 10, 20 to receive the scope 70 in the receiving cavity. It is worth mentioning that the objective end 711 and the sight end 712 of the scope 70 are located at two opposite ends of the receiving cavity.

On the other hand, the multiple rail arrangement 30 comprises at least a mounting rail 31 formed on at least one of the first coupling member 10 and the second coupling member 20, wherein the mounting rail 31 allows the scope 70 to be mounted onto at least one additional firearm accessory so as to eliminate a need to individually attach the additional firearm accessory to the firearm 80.

The first coupling member 10 comprises a first semi-tubular body 12 having a radius of curvature substantially the same as that of the scope 70, and is fittedly mounted onto the upper half portion thereof. Moreover, the first coupling member 10 has a predetermined length which covers a predetermined portion of the scope 70. The first coupling member 10 further has a plurality of first through slots 13 formed on the first tubular body 12 and aligned with a plurality of adjustment knobs 72 of the scope 70. Thus, the adjustment knobs 72 can be conveniently accessed by the shooter even though the first coupling member 10 is mounted on the scope 70. It is worth mentioning that each of the first through slots 13 may be embodied as having different shapes so as to fit different sizes and shapes of the adjustment knobs 72.

On the other hand, the second coupling member 20 comprises a second semi-tubular body 23 having a radius of curvature substantially the same as that of the lower half portion of the scope 70. The second semi-tubular body 23 is fittedly mounted onto the lower half portion of the scope 70 and is arranged to be securely mounted with the first tubular member 10 so as to fittedly and substantially embed the entire perimeter of the scope 70. Similarly, the second coupling member 20 further has a plurality of second through slots 26 formed on the second tubular body 23 and aligned with a plurality of adjustment knobs 72 of the scope 70. Thus, the adjustment knobs 72 can be conveniently accessed by the shooter even though the second coupling member 20 is mounted on the scope 70. As the first through slots 13, each of the second through slots 26 may be embodied as having different shapes so as to fit different sizes and shapes of the adjustment knobs 72.

According to the above preferred embodiment of the present invention, the multiple rail arrangement 30 further comprises a plurality of connectors 32 spacedly provided on the first coupling member 10 and the second coupling member 20 so as to securely mount the first coupling member 10 and the second coupling member 20 together on the scope 70. More specifically, each of the connectors 32 is a screw having a threaded portion formed thereon. The first coupling member 10 has a plurality of first connecting holes 11 spacedly formed thereon, while the second coupling member 20 has a plurality of second connecting holes 22 formed thereon and aligned with the first connecting holes 11 respectively, wherein each of the connectors 32 is arranged to penetrate a corresponding first connecting hole 11 and a corresponding second connecting hole 22 for mounting the first coupling member 10 with the second coupling member 20. It is worth mentioning that when connecting the first and the second coupling member 10, 20, the connectors 32 do not physically contact the scope 70 and do not in any way cause physical damage to the scope 70.

In particular, the first connecting holes 11 are spacedly formed along two bottom longitudinal edges of the first semi-tubular body 12 of the first coupling member 10. The second connecting holes 22 are spacedly formed along two upper longitudinal edges of the second semi-tubular body 23 of the second coupling member 20, wherein when the bottom longitudinal edges of the first coupling member 10 are coupled with the upper longitudinal edges of the second coupling member 20 to align the first connecting holes 11 with the second connecting holes 22 respectively, the connectors 32 are penetrated through the first and second connecting holes 11, 22 for mounting the first coupling member 10 with the second coupling member 20.

Hence, the tighter is the screwing by the connectors 32, the more secure is the connection between the first coupling member 10 and the second coupling member 20. However, the tight and secure connection between the first coupling member 10 and the second coupling member 20 does not impart any damage to the firearm accessory (i.e. the scope 70 in this preferred embodiment) because the first and the second coupling members 10, 20 are fittedly engaged with the scope 70.

As shown in FIG. 1 to FIG. 4 of the drawings, the first coupling member 10 further comprises a plurality of first mounting panels 14 transversely and outwardly extended from the first tubular body 12 at opposite sides respectively, wherein the first mounting panels 14 are longitudinally and spacedly extended along the first semi-tubular body 12.

The second coupling member 20 further comprises a plurality of second mounting panels 24 transversely and outwardly extended from the second tubular body 23 at opposite sides and aligned with the first mounting panels 14 respectively. The second mounting panels 14 are longitudinally and spacedly extended along the second semi-tubular body 23.

The first connecting holes 11 are spacedly formed on the first mounting panels 14 along the two bottom longitudinal edges of the first semi-tubular body 12 while the second connecting holes 22 are formed on the second mounting panels 24 along two upper longitudinal edges of the second semi-tubular body 23. Thus, in order to mount the first coupling member 10 with the second coupling member 20, each of the connectors 32 is arranged to pass through the first connecting hole 11 and a corresponding second connecting hole 22. Note that each of the connectors 32 has a threaded portion and the first and the second connecting holes 11, 22 are bored holes so that the connection between the first coupling member 10 and the second coupling member 20 can be tightened by screwing the connectors 32 into the first and the second connecting holes 11, 22. In other words, by tightening the first and the second coupling member 10, 20, they are securely mounted together (i.e. with respect to each other) and is peripherally mounted on the scope 70.

The second coupling member 20 further comprises a mounting base 25 provided at a bottom side of the second tubular body 23, wherein the mounting base 25 is arranged to be securely and detachably mounted onto the firearm rail 81 of the firearm 80. More specifically, the mounting base 25 comprises a plurality of connecting knobs 251 and has an engagement slot 252 formed on the bottom side of the mounting base 25 for mounting on the firearm rail 81 of the firearm 80.

According to the preferred embodiment, the mounting rail 31 is arranged to guide the additional firearm accessory to be detachably mounted along the first and/or second coupling members 10, 20. Therefore, the mounting rail 31 provides a guiding function to the additional firearm accessory to be mounted on the scope 70. For example, “Picatinny rail system or “Weaver” rail system is a protruded rail system comprising a plurality of raised ridges, wherein the firearm accessory can be mounted at the protruded rail system by transversely sliding an adapter of the firearm accessory at the protruded rail system and fastening the adapter at the protruded rail system via a bolt. In other words via the protruded rail system, the additional firearm accessory can be mounted at the protruded rail system at the transverse direction of the scope 70.

As shown in FIG. 2 to FIG. 4, the mounting rail of the present invention is indented rail system, wherein the additional firearm accessory can be mounted at the indented rail system at the longitudinal direction of the scope 70. In particular, the mounting rail 31 is a Keymod rail system which comprises a plurality of keymod slots. Each of the keymod slots has a keyhole configuration defining an enlarged slot portion with larger diameter and a narrow slot portion extended therefrom, wherein the keymod slot is chamfered on the backside. Therefore, a keymod nut at the additional firearm accessory can be disposed in the enlarged slot portion and slid to the narrower slot portion in order to secure the additional firearm accessory. The Keymod rail system can solve the existing problems by providing an ergonomic mounting way to mount the additional firearm accessory at the firearm corresponding to the discharge axis thereof, and by substantially reducing the overall weight of the firearm incorporating with the Keymod mounting slots.

In particular, the first and second coupling members 10, 20 are coupled with each other to form the elongated tubular member defining a plurality of longitudinal faces, wherein the mounting rail 31 is formed on at least of the longitudinal faces.

Each of the mounting rails 31 comprises a rail base 311 formed at the first coupling member 10 at each longitudinal face thereof, and a plurality of rail guiders 312 spacedly formed on the rail base 311 to define a rail channel 313 for an additional firearm accessory to be mounted thereon. Accordingly, the rail guiders 312 are a series of through rail guiders aligned along a longitudinal direction of the first coupling member 10. In other words, the series of rail guiders 312 are formed at each longitudinal face of the first coupling member 10.

According to the preferred embodiment of the present invention, the multiple rail arrangement 30 comprises three mounting rails 31 formed on top, and at two sides of the first coupling member 10 respectively. Thus, the first mounting panels 14 are protruded from two sides of the first tubular body 12 and two of the rail bases 311 are extended from the first mounting panels 14 respectively. Furthermore, the remaining rail base 311 is extended from the top side of the first tubular body 12 for forming the corresponding rail channel 313.

In particular, each of the rail guiders 312 is a keymod slot formed on the rail base 311, wherein the rail channel 313 is defined at a longitudinal slot space between the enlarged slot portion and the narrow slot portion of each of the keymod slot. In other words, unlike the protruded rail system, there is no protrusion outwardly protruded from the rail base 311 of the present invention.

It is worth mentioning that the each of the rail bases 311 extends along the longitudinal direction of the scope 70 so as to form the rail channel 313. Thus, the additional firearm accessory 80′, which is a locker ring, is slidably engaged with the rail channel 313 for mounting onto the sighting device of the present invention, as shown in FIG. 5.

The operation of the present invention is as follows: a user or the manufacturer of the firearm 80 may mount the sighting device of the present invention onto the firearm 80 preferably through the firearm rail 81 and the mounting base 25. In particular, the first coupling member 10 is coupled with the second coupling member 20 to encircle the lens housing 71 of the scope 70 within the first and second coupling members 10, 20. Then, the mounting base 25 is mounted at the firearm rail 81 of the firearm 80 to support the scope 70 on the firearm 80.

After that, the user may then mount additional firearm accessory onto one of mounting rails 31 so as to mount the additional firearm accessory 80′, such as a locker ring, a flashlight module, a laser pointer or another scope onto the firearm 80, as shown in FIG. 5. The most important point is that the firearm accessories need not be individually mounted onto the firearm 80. Rather, the sighting device provides a platform for mounting many firearm accessories. The scope 70 described above is merely an example of firearm accessory and it can be embodied as different devices.

As shown in FIG. 6 to FIG. 9, a multiple sighting device according to a second embodiment illustrates an alternative mode of the first embodiment, wherein the first and second coupling members 10A, 20A are coupled with each other to form a rail apparatus to detachably couple with the scope 70.

As it is mentioned above, the scope 70 comprises a tubular lens housing 71 that lens are supported therein to define an objective end 711 and a sight (ocular) end 712. Conventionally, the scope 70 can be directly mounted to the firearm rail 81 of the firearm 80. In other words, the scope 70 can be an existing scope device to be detachably mounted to the firearm 80. In particular, the scope 70 comprises a mounting base 75 provided at a bottom side of the lens housing 71, wherein the mounting base 75 is arranged to be securely and detachably mounted onto the firearm rail 81 of the firearm 80. More specifically, the mounting base 75 comprises an actuator 751 and has an engagement slot 752 formed on the bottom side of the mounting base 75 for mounting on the firearm rail 71 of the firearm 70. Accordingly, the actuator 751 is a locking mechanism serving as a quick releasing mechanism to quickly lock and unlock the mounting base 75 at the firearm rail 71 of the firearm 70. It is appreciated that the actuator 751 can also be the connecting knob for mounting the mounting base 75 on the firearm rail 81 of the firearm 80.

The first coupling member 10A according to the second embodiment has the same structural configuration of that of the first embodiment, wherein the first coupling member 10A is supported on an upper portion of the scope 70. In particular, the first coupling member 10A is supported on the upper half portion of the lens housing 71 of the scope 70. The first coupling member 10A comprises a first semi-tubular body 12A having a radius of curvature substantially the same as that of the lens housing 71 of the scope 70, and is fittedly mounted onto the upper half portion thereof. Moreover, the first coupling member 10A has a predetermined length which covers a predetermined portion of the scope 70. The first coupling member 10A further has a plurality of first through slots 13A formed on the first tubular body 12A and aligned with a plurality of adjustment knobs 72 of the scope 70. Thus, the adjustment knobs 72 can be conveniently accessed by the shooter even though the first coupling member 10A is mounted on the scope 70. It is worth mentioning that each of the first through slots 13A may be embodied as having different shapes so as to fit different sizes and shapes of the adjustment knobs 72.

The second coupling member 20A according to the second embodiment has the similar structural configuration of that of the first embodiment, wherein the second coupling member 20A is supported on a lower portion of the lens housing 71 of the scope 70. In particular, the second coupling member 20A is supported on the lower half portion of the lens housing 71 of the scope 70. Accordingly, when the first and second coupling members 10A, 20A are coupled with each other to form an elongated tubular member, an elongated receiving cavity is formed within the first and second coupling members 10A, 20A to receive the scope 70 in the receiving cavity. It is worth mentioning that the objective end 711 and the sight end 712 of the scope 70 are located at two opposite ends of the receiving cavity.

The second coupling member 20A comprises a second semi-tubular body 23A having a radius of curvature substantially the same as that of the lower half portion of the lens housing 71 of the scope 70. The second semi-tubular body 23A is fittedly mounted onto the lower half portion of the scope 70 and is arranged to be securely mounted with the first tubular member 10A so as to fittedly and substantially embed the entire perimeter of the scope 70. Similarly, the second coupling member 20A further has a plurality of second through slots 26A formed on the second tubular body 23A and aligned with a plurality of adjustment knobs 72 of the scope 70. Thus, the adjustment knobs 72 can be conveniently accessed by the shooter even though the second coupling member 20A is mounted on the scope 70. As the first through slots 13A, each of the second through slots 26A may be embodied as having different shapes so as to fit different sizes and shapes of the adjustment knobs 72.

The second coupling member 20A further has an elongated guiding slot 27A for enabling the mounting base 75 of the scope 70 passing through to mount on the firearm rail 81 of the firearm 80. The guiding slot 27A is a through slot formed at the bottom side of the second semi-tubular body 23A, wherein when the mounting base 75 of the scope 70 passes through the guiding slot 27A, the lower half portion of the lens housing 71 of the scope 70 is supported on the second semi-tubular body 23A.

Therefore, the first and second coupling members 10A, 20A are coupled with each other to encircle the lens housing 71 of the scope 70, such that the first and second coupling members 10A, 20A can be incorporated with any existing scope device having the mounting base 75. The existing scope device does not require to alter the original structure to incorporate with the first and second coupling members 10A. 20A.

Similarly, the rail arrangement 30A comprises at least a mounting rail 31A formed on at least one of the first coupling member 10A and the second coupling member 20A, wherein the mounting rail 31A allows the scope 70 to be mounted onto at least one additional firearm accessory so as to eliminate a need to individually attach the additional firearm accessory to the firearm 80.

The rail arrangement 30A further comprises a plurality of connectors 32A spacedly provided on the first coupling member 10A and the second coupling member 20A so as to securely mount the first coupling member 10A and the second coupling member 20A together on the scope 70. More specifically, each of the connectors 32A is a screw having a threaded portion formed thereon. The first coupling member 10A has a plurality of first connecting holes 11A spacedly formed thereon, while the second coupling member 20A has a plurality of second connecting holes 22A formed thereon and aligned with the first connecting holes 11A respectively, wherein each of the connectors 32A is arranged to penetrate a corresponding first connecting hole 11A and a corresponding second connecting hole 22A for mounting the first coupling member 10A with the second coupling member 20A. It is worth mentioning that when connecting the first and the second coupling member 10A, 20A, the connectors 32A do not physically contact the scope 70 and do not in any way cause physical damage to the scope 70.

In particular, the first connecting holes 11A are spacedly formed along two bottom longitudinal edges of the first semi-tubular body 12A of the first coupling member 10A. The second connecting holes 22A are spacedly formed along two, upper longitudinal edges of the second semi-tubular body 23A of the second coupling member 20A, wherein when the bottom longitudinal edges of the first coupling member 10A are coupled with the upper longitudinal edges of the second coupling member 20A to align the first connecting holes 11A with the second connecting holes 22A respectively, the connectors 32A are penetrated through the first and second connecting holes 11A, 22A for mounting the first coupling member 10A with the second coupling member 20A.

Hence, the tighter is the screwing by the connectors 32A, the more secure is the connection between the first coupling member 10A and the second coupling member 20A. However, the tight and secure connection between the first coupling member 10 and the second coupling member 20A does not impart any damage to the firearm accessory (i.e. the scope 70 in this preferred embodiment) because the first and the second coupling members 10A, 20A are fittedly engaged with the scope 70.

As shown in FIG. 6 to FIG. 9 of the drawings, the first coupling member 10A further comprises a plurality of first mounting panels 14A transversely and outwardly extended from the first tubular body 12A at opposite sides respectively, wherein the first mounting panels 14A are longitudinally and spacedly extended along the first semi-tubular body 12A.

The second coupling member 20A further comprises a plurality of second mounting panels 24A transversely and outwardly extended from the second tubular body 23A at opposite sides and aligned with the first mounting panels 14A respectively. The second mounting panels 14A are longitudinally and spacedly extended along the second semi-tubular body 23A.

The first connecting holes 11A are spacedly formed on the first mounting panels 14A along the two bottom longitudinal edges of the first semi-tubular body 12A while the second connecting holes 22A are formed on the second mounting panels 24A along two upper longitudinal edges of the second semi-tubular body 23A. Thus, in order to mount the first coupling member 10A with the second coupling member 20A, each of the connectors 32A is arranged to pass through the first connecting hole 11A and a corresponding second connecting hole 22A. Note that each of the connectors 32A has a threaded portion and the first and the second connecting holes 11A, 22A are bored holes so that the connection between the first coupling member 10A and the second coupling member 20A can be tightened by screwing the connectors 32A into the first and the second connecting holes 11A, 22A. In other words, by tightening the first and the second coupling member 10A, 20A, they are securely mounted together (i.e. with respect to each other) and is peripherally mounted on the scope 70.

According to the second embodiment, the mounting rail 31A is arranged to guide the additional firearm accessory to be detachably mounted along the first and/or second coupling members 10A, 20A.

In particular, the mounting rail 31A is a Keymod rail system which comprises a plurality of keymod slots. In particular, the first and second coupling members 10A, 20A are coupled with each other to form the elongated tubular member defining a plurality of longitudinal faces, wherein the mounting rail 31A is formed on at least of the longitudinal faces.

Each of the mounting rails 31A comprises a rail base 311A formed at the first coupling member 10A at each longitudinal face thereof, and a plurality of rail guiders 312A spacedly formed on the rail base 311A to define a rail channel 313A for an additional firearm accessory to be mounted thereon. Accordingly, the rail guiders 312A are a series of through rail guiders aligned along a longitudinal direction of the first coupling member 10A. In other words, the series of rail guiders 312A are formed at each longitudinal face of the first coupling member 10A.

According to the preferred embodiment of the present invention, the multiple rail arrangement 30A comprises three mounting rails 31A formed on top, and at two sides of the first coupling member 10A respectively. Thus, the first mounting panels 14A are protruded from two sides of the first tubular body 12A and two of the rail bases 311A are extended from the first mounting panels 14A respectively. Furthermore, the remaining rail base 311A is extended from the top side of the first tubular body 12A for forming the corresponding rail channel 313A.

In particular, each of the rail guiders 312A is a keymod slot formed on the rail base 311A, wherein the rail channel 313A is defined at a longitudinal slot space between the enlarged slot portion and the narrow slot portion of each of the keymod slot. In other words, unlike the protruded rail system, there is no protrusion outwardly protruded from the rail base 311A of the present invention.

It is worth mentioning that the each of the rail bases 311A extends along the longitudinal direction of the scope 70 so as to form the rail channel 313A.
