An air gun control assembly, an automatic firing device, and an air gun.

Abstract

This invention provides an air gun control assembly, an automatic firing device, and an air gun, relating to the field of sports equipment. The device internally comprises a cylinder assembly, an air supply unit, a hammer mechanism, a transmission mechanism, and a trigger mechanism. The first cylinder of the cylinder assembly is divided into two sub-chambers by a piston unit of the transmission mechanism. The air supply unit continuously supplies air to the two sub-chambers. Then, through the linkage between the trigger mechanism, the hammer mechanism, and the transmission mechanism, the air pressure in the two sub-chambers changes differently, resulting in different pressures acting on the two surfaces of the piston unit with different areas. This causes the piston unit to reciprocate, thereby enabling each mechanism to move in conjunction with the piston unit. This allows the air gun to automatically load and fire continuously, improving the user experience.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] like Figure 1As shown in the figure, an air gun control assembly is disclosed in an embodiment of the present invention. The air gun control assembly includes a cylinder component 100, an air supply unit 200, a valve control unit 300, a transmission mechanism 400, and a trigger mechanism 500. The cylinder component 100 includes a first cylinder 110 and a second cylinder 120. The first cylinder 110 is provided with a first air inlet 1110, a second air inlet 1120, and a first exhaust port 1130. The second cylinder 120 is provided with a third air inlet 1210 communicating with the first exhaust port 1130, a second exhaust port 1220 for supplying gas for bullet firing, a valve spring unit 1240, and a valve 1230. The valve spring unit 1240 is used to push the valve 1230 to a closed position, which is used to close the second exhaust port 1220. The valve control unit 300 is used to control the state of the valve 1230. The gas supply unit 200 is used to provide constant pressure gas. Specifically, the gas supply unit 200 is used to provide constant pressure gas to the cylinder component and is connected to the first air inlet 1110 through a first air inlet pipe and to the second air inlet 1120 through a second air inlet pipe. 0. Connectivity; Transmission mechanism 400, including piston unit 410 and linkage spring 420 connected to piston unit 410, piston unit 410 is adapted to first cylinder chamber 110, linkage spring 420 is adapted to valve control unit 300, piston unit 410 is used to divide first cylinder chamber 110 into first sub-chamber 1140 and second sub-chamber 1150, first sub-chamber 1140 is connected to first air intake 1110, second sub-chamber 1150 is connected to second air intake 1120, piston unit 410 includes a first working surface 440 facing first sub-chamber 1140 and a second working surface 450 facing second sub-chamber 1150, the area of ​​first working surface 440 is larger than the area of ​​second working surface 450; trigger mechanism 500, used to control linkage spring to move, so as to control the state of valve control unit 300 through linkage spring 420. A first air intake pipe is independently provided between the air supply unit 200 and the first air inlet 1110, and a second air intake pipe is independently provided between the air supply unit 200 and the second air inlet 1120. The gas flow rate of the first air intake pipe is less than that of the second air intake pipe. By differentiating the first and second air intake pipes, the movement distance of the piston unit 410 in the first cylinder chamber 110 can be effectively increased, and the linkage effect of the piston unit on various mechanisms can be better realized. The technical solution of this embodiment uses the different pressures acting on the two working surfaces (first working surface 440 and second working surface 450) of the piston unit 410 under different states in the two sub-chambers (first sub-chamber 1140 and second sub-chamber 1150) to make the piston unit 410 reciprocate, thereby making various mechanisms move in linkage with the piston unit 410, so that the air gun has the function of automatic loading and continuous firing, improving the user experience.

[0050] It should be noted that the gas supply unit may include a gas cylinder and a constant pressure gas valve connected to the gas cylinder, or it may include a gas cylinder and other constant pressure units connected to the gas cylinder. This embodiment does not specifically limit it.

[0051] In some optional embodiments, a first intake pipe is independently provided between the air supply unit 200 and the first air inlet 1110, and a second intake pipe is independently provided between the air supply unit 200 and the second air inlet 1120. The gas flow rate of the first intake pipe is less than that of the second intake pipe. By differentiating the first and second intake pipes, the movement distance of the piston unit 410 in the first cylinder chamber 110 can be effectively increased, and the linkage effect of the piston unit on various mechanisms can be better realized.

[0052] In some optional embodiments, a main gas supply pipe is provided between the gas supply unit and the first gas intake pipe, and a second gas intake pipe is connected to the main gas supply pipe. The gas flow rate of the first gas intake pipe is less than that of the second gas intake pipe, the gas flow rate of the second gas intake pipe is slightly less than that of the main gas supply pipe, and the gas flow rate of the main gas supply pipe is slightly less than that of the barrel. By setting the gas flow rates of the first gas intake pipe, the second gas intake pipe, the main gas supply pipe, and the barrel differently, the travel distance of the piston unit 410 in the first cylinder chamber 110 can be effectively increased, the linkage effect of the piston unit on various mechanisms can be better realized, and the bullet firing effect can be improved.

[0053] In some alternative embodiments, the first cylinder 110 is provided with only a first air inlet 1110 and a first exhaust port 1130, while the second cylinder 120 is provided with a third air inlet 1210 communicating with the first exhaust port 1130 and a second exhaust port 1220 for supplying air to the bullet. A connecting pipe is provided on the piston unit 410 to connect the first sub-chamber 1140 and the second sub-chamber 1150, so that the air supply unit can supply air to both sub-chambers 1140 and 1150. This structure also allows for different pressures on the two working surfaces (first working surface 440 and second working surface 450) of the piston unit 410, causing the piston unit 410 to reciprocate. This enables various mechanisms to move in conjunction with the piston unit 410, giving the air gun the function of automatic loading and continuous firing, thus improving the user experience.

[0054] It should be noted that the first working surface 440 of the piston unit 410 can be a concave plane. The first working surface 440 is connected to the first air inlet 1110 to prevent the air supply unit 200 from still supplying air to the first sub-chamber 1140 when the first working surface 440 of the piston unit 410 is attached to the inner wall of the first cylinder 110.

[0055] like Figure 1 As shown, the automatic firing device includes a cylinder assembly 100, an air supply unit 200, a hammer mechanism 300, a transmission mechanism 400, a trigger mechanism 500, and a bullet turntable mechanism 600. The cylinder assembly 100 includes a first cylinder 110 and a second cylinder 120. The first cylinder 110 is provided with a first air inlet 1110, a second air inlet 1120, and a first exhaust port 1130. The second cylinder 120 is provided with a third air inlet 1210 communicating with the first exhaust port 1130, a second exhaust port 1220 for supplying air to the bullet, a valve spring unit 1240, and a valve 1230. The valve spring unit 1240 is used to push the valve 1230 to a closed position, which closes the second exhaust port 1220. The gas supply unit 200 provides constant-pressure gas and is connected to the first air inlet 1110 via a first air inlet pipe and to the second air inlet 1120 via a second air inlet pipe. The hammer mechanism 300 includes a hammer body 310 and an ejection unit 320. The hammer body 310 is provided with a first linkage part 3110 and a second linkage part 3120. The ejection unit 320 ejects the hammer body 310 in a first direction to strike the valve 1230, which moves in the first direction to connect the third air inlet 1210 and the second exhaust port 1220. The air passage and transmission mechanism 400 include a piston unit 410 and a linkage spring 420 connected to the piston unit 410. The piston unit 410 is adapted to the first cylinder chamber 110, and the linkage spring 420 is adapted to the first linkage part 3110. The piston unit 410 is used to divide the first cylinder chamber 110 into a first sub-chamber 1140 and a second sub-chamber 1150. The first sub-chamber 1140 communicates with the first air inlet 1110, and the second sub-chamber 1150 communicates with the second air inlet 1120. The piston unit 410 includes a section facing the first sub-chamber 1140. The first working surface 440 and the second working surface 450 facing the second sub-chamber 1150 are respectively provided. The area of ​​the first working surface 440 is larger than the area of ​​the second working surface 450. The trigger mechanism 500 is used to control the movement of the linkage bullet to control the connection state between the linkage bullet 420 and the first linkage part 3110 of the hammer mechanism 300. The bullet turntable mechanism 600 includes a turntable body 610 for placing bullets and a rotation mechanism 620. The rotation mechanism 620 is used to move according to the position change of the second linkage part 3120 to drive the turntable body 610 to rotate.

[0056] Before the trigger mechanism 500 is pressed, all components are in their original positions. At this time, the air supply unit 200 supplies air to the first sub-chamber 1140 of the first cylinder 110 through the first air inlet 1110. The first sub-chamber 1140 is connected to the third air inlet 1210 of the second cylinder 120 through the first exhaust port 1130, supplying air to the second cylinder 120. At this time, the air pressure in the first sub-chamber 1140 and the second sub-chamber 1150 is the same. However, since the area of ​​the first working surface 440 is larger than the area of ​​the second working surface 450, the force exerted by the air pressure on the first working surface is greater than the force exerted by the air pressure on the second working surface. The force pushes the first working surface of the piston unit 410 in the second direction. At this time, the piston unit 410 pushes the linkage spring 420 in the second direction, and the linkage spring 420 pushes the hammer body 310 in the second direction. The hammer body 310 compresses the ejection unit 320 and drives the rotating mechanism 620 to move in the second direction. At this time, the rotating mechanism 620 drives the turntable to rotate one increment, completing the loading and reloading. After the trigger mechanism 500 contacts the linkage spring 420, it stops the piston from moving in the second direction. The valve 1230 in the second cylinder 120 is in a closed state, and there is no passage between the third air intake 1210 and the second exhaust 1220.

[0057] After the trigger mechanism 500 is pulled, the trigger mechanism 500 pushes the linkage element 420, causing the linkage element 420 to disengage from the first linkage part 3110. At this time, the linkage element 420 stops applying the second-direction force to the hammer body 310, that is, there is no second-direction force between the hammer body 310 and the ejection unit 320. At this time, the ejection unit 320 releases elastic potential energy and pushes the hammer body 310 to be ejected rapidly in the first direction, so that the hammer body 310 hits the valve 1230. At this time, the valve 1230 moves in the first direction and compresses the valve elastic unit 1240, releasing the passage from the third air inlet 1210 to the second exhaust port 1220. The second exhaust port 1220 discharges the compressed air into the turntable body 610 in the bullet turntable mechanism 600, pushing the bullet in the turntable body 610 to complete the firing. Since the air inside the first sub-chamber has been used to fire the bullet, the air pressure in the second sub-chamber 1150 is greater than that in the first sub-chamber 1140. Therefore, the force exerted by the air pressure on the second working surface 450 is greater than that on the first working surface 440. The force exerted by the air pressure on the second working surface 450 in the first direction causes the second working surface 450 of the piston unit 410 to move in the first direction. At this time, the linkage element 420 disengages from the trigger mechanism 500 and returns to the first linkage part 3110.

[0058] After the bullet is fired from the barrel 700, the valve 1230 automatically resets under the force of the valve spring unit 1240, sealing the passage between the third air inlet 1210 and the second exhaust port 1220. The first sub-chamber 1140 receives air from the air supply unit 200, and the air pressure in the first sub-chamber 1140 gradually increases. Therefore, the force exerted by the air pressure on the first working surface 440 also increases until it exceeds the force exerted by the air pressure on the second working surface 450. This force pushes the first working surface 440 of the piston unit 410 in the second direction. As the piston unit 410 moves in the second direction, it again moves the hammer body 310 in the second direction to compress the ejection unit 320 again, and drives the rotating mechanism 620 to rotate one notch to complete the reloading. Since the trigger mechanism 500 is still in the pulled state, when the linkage element 420 comes into contact with the trigger mechanism 500, it will be subjected to the force of the trigger mechanism 500, causing the linkage element 420 to disengage from the first linkage part 3110 again. At this time, the linkage element 420 stops applying the second direction force to the hammer body 310, and then the principle of bullet firing in the above embodiment is repeated.

[0059] After the trigger mechanism 500 is released, it stops applying pressure to the linkage spring 420, which returns to its original position and no longer disengages from the first linkage part 3110 of the hammer body 310. At this time, the force from air pressure on the first working surface is greater than that on the second working surface. This causes the force to push the first working surface of the piston unit 410 in the second direction. The piston unit 410 then drives the linkage spring 420 forward in the second direction, and through the first linkage part 3110, it again drives the hammer body 310 to compress the ejection unit 320. At this time, the hammer body 310 drives the rotating mechanism 620 to rotate, reloading. Pulling the trigger mechanism 500 again allows the linkage spring 420 to apply force to the hammer body 310 again. With the above devices working together, the technical solution of this embodiment achieves automatic continuous firing by using the different pressures acting on the two working surfaces of the piston unit in different states of the two sub-chambers, causing the piston unit to move back and forth. This allows each component to move in conjunction with the piston unit, thereby achieving automatic continuous firing.

[0060] like Figure 2 As shown, in some alternative embodiments, the trigger mechanism 500 includes a trigger 510 and a trigger spring 520, one end of which is fixed to the trigger 510, and the other end is fixed to the housing of the automatic firing device. When the trigger 510 is pulled, the trigger 510 pulls the trigger spring 520, which accumulates elastic potential energy. When the trigger 510 is released, the trigger spring 520 releases the elastic potential energy, resetting the trigger. The trigger spring 520 can also be used to fix the trigger 510, which is also rotatably mounted on the housing.

[0061] like Figure 3 As shown, in some optional embodiments, the linkage spring 420 further includes an internally disposed linkage spring 430, through which the linkage spring applies pressure to the piston unit 410. When the trigger 510 is pulled, the trigger 510 applies pressure to the linkage spring 420, and when the linkage spring 420 applies pressure to the linkage spring 430, the linkage spring 430 applies pressure to the piston unit 410, simultaneously accumulating elastic potential energy. When the linkage spring 420 stops applying pressure to the linkage spring 430, the linkage spring 430 releases its elastic potential energy, resetting the linkage spring 420.

[0062] like Figure 3 , 7 As shown, in some optional embodiments, the linkage spring 420 is divided into two parts. When the linkage spring 420 is not subjected to the force of the trigger, the first part of the linkage spring 420 abuts against the piston unit 410, and the second part of the linkage spring 420 at the slot is separated from the piston unit 410. When the linkage spring 420 is subjected to the force of the trigger 510, the first part of the linkage spring 420 is separated from the piston unit 410, and the second part of the linkage spring 420 at the slot abuts against the piston unit 410.

[0063] like Figure 4 As shown, in some optional embodiments, the hammer mechanism 300 includes a hammer body 310 and an ejection unit 320. The hammer body 310 includes a first linkage part 3110 and a second linkage part 3120. The first linkage part 3120 is located at the bottom of the hammer body 310 and cooperates with the linkage spring 420. The second linkage part 3120 is located at the top of the hammer body 310 and cooperates with the rotation mechanism 620. The first linkage part 3120 and the second linkage part 3120 move in the same direction as the hammer body 310, and all three are parallel to each other.

[0064] When the linkage spring 420 is pushed by the trigger 510, the linkage spring 420 will push the hammer body 310 backward through the first linkage part 3110. At this time, the hammer body 310 compresses the ejection unit 320 and drives the rotating mechanism 620. When the ejection unit 320 is released by the hammer body 310, the hammer body 310 will be ejected until it impacts the valve 1230 in the second cylinder 120. After the valve 1230 is impacted, it compresses the valve elastic unit 1240 and releases the passage between the third intake port 1210 and the second exhaust port 1220. The valve elastic unit 1240 accumulates elastic potential energy when it is compressed and releases and resets the valve 1230 after the impact.

[0065] It should be noted that the valve spring unit 1240 can be a spring structure, a spring structure, or a spring block structure; this embodiment does not specifically limit it.

[0066] like Figure 1 , 5 As shown, in some optional embodiments, the hammer body drives the rotating mechanism 620 via the second linkage 3120. The rotating mechanism 620 includes a first rotating rod 6210, a second rotating rod 6220, a rotating clamp 6230, a first return spring 6240, and a second return spring 6250. The first rotating rod 6210 and the second rotating rod 6220 are movably connected, and the second rotating rod 6220 is movably connected to the rotating clamp 6230. The first return spring 6240 is used to reset the first rotating rod 6210, and the second return spring 6250 is used to reset the rotating clamp 6230. The rotating clamp 6230 clamps the turntable body 610 and drives the turntable body 610 to rotate. When the hammer body 310 drives the rotating mechanism 620, the first rotating rod 6210 retracts, compressing the first return spring 6240 and pulling the second rotating rod 6220. The second rotating rod 6220 drives the rotating chuck 6230, which engages any slot on the turntable body 610. Rotating the turntable body 610 one notch completes the cartridge change. During this process, the second return spring 6250 fixes the rotating chuck 6230, preventing it from losing its connection with the turntable body 610 during movement.

[0067] like Figure 5 As shown, in some optional embodiments, one end of the first return spring 6240 is connected to the first rotating rod 6210, and the other end is connected to the housing, thus fixing the first return spring 6240. One end of the second return spring 6250 is connected to the rotating clamp 6230, and the other end is connected to the housing, thus fixing the second return spring 6250.

[0068] It should be noted that the rotating clamp 6230 has an inverted triangular structure. When the first rotating rod 6210 moves in the first direction, the second rotating rod 6220 moves along with it, causing the rotating clamp 6230 to move downwards. During this downward movement, the clamp 6230 is acted upon by the locking block, causing one end of the rotating clamp 6230 to tilt upwards. At this point, one end of the rotating clamp 6230 no longer acts on the turntable body 610, or the distance between one end of the rotating clamp 6230 and the turntable body 610 is very small. 610 has relative displacement; therefore, when the first rotating rod 6210 moves in the second direction, the second rotating rod 6220 will move with the first rotating rod 6210, causing the rotating chuck 6230 to move upward from the low position. At the same time, one end of the rotating chuck 6230 will reset, and the rotating chuck 6230 will engage with the turntable body 610. Since the position of the rotating chuck 6230 acting on the turntable body 610 has changed, the rotating chuck 6230 will drive the turntable body 610 to rotate as it moves upward with the second rotating rod 6220, thereby completing the cartridge replacement.

[0069] like Figure 6 As shown, in some optional embodiments, the second exhaust port 1220 is connected to the bullet turntable mechanism 600. Specifically, when the valve 1230 opens the passage between the third air inlet 1210 and the second exhaust port 1220, air is guided from the second exhaust port 1220 to the bullet magazine in the turntable body 610, which is in the ready-to-fire position. At this time, the air will strike the bullet in the turntable body, and the bullet will be fired.

[0070] like Figure 7 As shown, in some alternative embodiments, an adjustable throttling unit 1620 is provided on the first intake duct.

[0071] In some alternative embodiments, a housing is also provided, inside which all the components of cylinder component 100, air supply unit 200, hammer mechanism 300, transmission mechanism 400, trigger mechanism 500, and bullet turntable mechanism 600 are housed.

[0072] In some alternative embodiments, an air gun is provided that includes the aforementioned automatic firing device, which can solve the same technical problems as the aforementioned automatic firing device and achieve the same technical effects as the aforementioned automatic firing device.

[0073] The following explanation is based on a specific example.

[0074] like Figures 2 to 8As shown, in use, first, all components of the cylinder assembly 100, hammer mechanism 300, transmission mechanism 400, trigger mechanism 500, and bullet turntable mechanism 600 are placed inside the air gun and fixed in place, using the gun body as the casing. The turntable body 610, with the bullets installed, is then installed into the gun body, and the air supply unit 200 begins pumping air into the first air inlet 1110 and the second air inlet 1120 at the bottom of the first cylinder 110. At this time, the air pressure in the first sub-chamber 1140 is equal to that in the second sub-chamber 1150. Since the area of ​​the first working surface 440 is larger than the area of ​​the second working surface 450, the force exerted on the first working surface 440 by the air pressure is greater than that exerted on the second working surface 450 by the air pressure, causing the force to push the first working surface of the piston unit 410 to move in the second direction. The piston unit 410 drives the linkage element 420 to move in the second direction. The linkage element 420 drives the hammer body 310 to move in the second direction and compresses the ejection unit 320. At this time, the hammer body 310 pulls the rotating mechanism 620 in the bullet turntable mechanism 600. When the hammer body 310 moves in the second direction, it drives the first rotating rod 6210 in the second direction. The first rotating rod 6210 compresses the first return spring 6240 and drives the second rotating rod 6220 to move. The second rotating rod 6220 drives the rotating chuck 6230, which drives the turntable body 610. At this time, the turntable body 610 rotates one notch to complete the loading of the bullet. The second return spring 6250 fixes the rotating chuck 6230 to prevent it from slipping out of the slot on the turntable body. During the movement of the linkage element 420 in the second direction, the linkage element 420 contacts the trigger 510 in the trigger mechanism 500. At this time, the valve 1230 in the second cylinder 120 is still closed, and there is no passage between the third intake port 1210 and the second exhaust port 1220.

[0075] Pulling the trigger 510 pushes the linkage spring 420, which compresses the linkage spring 430 and disengages from the first linkage part 3110. At this time, the linkage spring 420 stops applying a force in the second direction to the hammer body 310, meaning there is no force in the second direction between the hammer body 310 and the ejection unit 320. The ejection unit 320 releases its elastic potential energy, propelling the hammer body 310 rapidly in the first direction so that it strikes the valve 1230. The valve 1230 then moves in the first direction and compresses the valve elastic unit 1240, opening a passage from the third air inlet 1210 to the second exhaust outlet 1220. The second exhaust outlet 1220 discharges the compressed air into the turntable body 610 in the bullet turntable mechanism 600, pushing the bullet in the turntable body 610 to complete the firing. Since the air in the first sub-chamber has been used to fire the bullet, the air pressure in the second sub-chamber is greater than that in the first sub-chamber. Therefore, the pressure force on the first contact surface of the piston unit is less than that on the second contact surface. This force pushes the second contact surface of the piston unit 410 to move in the first direction, causing the piston unit 410 to move again in the first direction. Meanwhile, the linkage spring 430 loses the applied pressure and resets the linkage spring 420. At this point, the linkage spring 420 disengages from the trigger 510 and returns to the first linkage part 3110.

[0076] After the bullet is fired from the barrel 700, the valve 1230, under the force of the valve spring unit 1240, will automatically return to the closed position to seal the passage between the third air inlet 1210 and the second exhaust outlet 1220. The air pressure in the first sub-chamber gradually increases, and the force exerted on the first action surface by the air pressure also gradually increases until it exceeds that on the second action surface. At this time, the force will push the first action surface of the piston unit 410 to move in the second direction, causing the piston unit 410 to move in the second direction. During the movement of the piston unit 410 in the second direction, the linkage element 420 again drives the hammer body 310 to move in the second direction to compress the ejection unit 320 again. At this time, the hammer body 310 will again drive the first rotating rod 6210 in the second direction. The first rotating rod 6210 compresses the first return spring 6240 and drives the second rotating rod 6220 to move. The second rotating rod 6220 drives the rotating latch 6230, which in turn drives the turntable body 610. At this time, the turntable body 610 rotates one notch to complete the loading of the bullet. The second return spring 6250 will fix the rotating latch 6230 to prevent it from slipping out of the slot on the turntable body. Since the trigger 510 is still in the pulled state, when the linkage element 420 contacts the trigger 510, it will be subjected to the force of the trigger 510, causing the linkage element 420 to disengage from the first linkage part 3110 again. At this time, the linkage element 420 stops applying the force in the second direction to the hammer body 310, and then the bullet firing principle in the above embodiment is repeated.

[0077] After the trigger 510 is released, it stops applying pressure to the linkage spring 420. The linkage spring 430 resets the linkage spring 420. Because the air pressure in the first sub-chamber 1140 is greater than that in the second sub-chamber 1150, the force on the first contact surface 440 of the piston unit 410 is greater than that on the second contact surface, causing the piston unit 410 to move in the second direction and drive the linkage spring 420 back to the first linkage part 3110. The linkage spring 420 then drives the hammer body 310 to move in the second direction again. The trigger spring 520 releases its elastic potential energy to pull the trigger 510 back to its original position. With the above devices working together, this invention uses the change in air pressure difference between the two sub-chambers to drive the piston to reciprocate, so that each component is linked to the movement of the piston, thereby achieving automatic continuous firing.

[0078] The above provides a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the present invention.
