Description
- The present application is based on, and claims priority from, Taiwan application number 110148028, filed Dec. 21, 2021, the disclosure of which is hereby incorporated by reference herein in its entirety.
- The invention relates to a firing device for weapons and ammunition, and more specifically, to a gun-type firing device using a caseless projectile.
- The firing devices of weapons mainly use propellant or gunpowder as a fuel. After the propellant or gunpowder is ignited, a high-pressure gas is generated in the chamber to push the warhead or projectile out. This firing device has defects.
- Conventional guns or firing devices have a complicated structure, and it is easy for maintenance. For example, the inside of a conventional gun barrel has a rifle (also known as Rifling), which is configured to allow a bullet to rotate along the longitudinal axis of the rifle when the bullet is fired, resulting in a gyroscopic effect to stabilize the trajectory, and then shoot at the target more accurately.
- However, the groove of the rifling in the barrel will accumulate sand. As a result, the bullet may jam and the barrel may explode.
- In addition, the magazine of a firearm has a small storage capacity, and the cartridge case occupies a lot of space of the magazine. Conventional bullets or shells have cases made of precious metals, which consume a large amount of precious metals and also cause a great economic burden.
- The primary object of the present invention is to provide a gun-type firing device using a caseless projectile, which does not have rifling in the gun barrel of the gun-type firing device.
- Another object of the present invention is to provide a gun-type firing device using a caseless projectile, which can prevent the gas generated after explosion from backlashing to reduce the recoil force after the gun-type firing device fires the caseless projectile.
- In order to achieve the above objects, the present invention provides a gun-type firing device using a caseless projectile. The caseless projectile has a bullet head and an impact seat at two ends thereof and a groove adjacent to the impact seat. The gun-type firing device comprises a gunstock, a gun bolt, and a gun barrel. The gun bolt is located on one side of the gunstock. The gun bolt includes a cocking handle and an extractor. The cocking handle is configured to perform a linear displacement movement along an extension direction of the gunstock. The extractor is located at one end of the cocking handle. The gun barrel is located on the gunstock and connected to one end of the gun bolt. The gun barrel does not have rifling. When the impact seat is against one side of the gun bolt and the extractor is engaged with the groove, the caseless projectile and the cocking handle perform the linear displacement movement for the caseless projectile to move out of the gun barrel.
- In an embodiment, the gun barrel is an elongate hollow cylindrical barrel. The gun barrel includes a muzzle area, a barrel area and a chamber area that are arranged in sequence from front to back. The chamber area includes at least three protrusions. The protrusions are arranged equidistantly on an annular inner wall of one end of the chamber area and are adjacent to the barrel area. When the caseless projectile is pushed into the chamber area, the protrusions scribe an outer surface of the caseless projectile to form a plurality of scribe lines, and the protrusions secure the caseless projectile in the gun barrel.
- Preferably, the protrusions have a height of 0.05 millimeters.
- Preferably, the cocking handle includes at least one raised block, and the chamber area has at least one guide groove. The raised block is disposed on an outer surface of one end of the cocking handle and is adjacent to the gun barrel. The guide groove is located on the inner wall of the chamber area. When the end of the cocking handle is pushed into the chamber area, the raised block and the guide groove cooperate with each other so that the gun bolt locks and closes the chamber area to prevent the recoil force generated by firing the caseless projectile.
- Preferably, the raised block has a first length, a first width, and a first height. The first length is 1 millimeter. The first width is 5 millimeters. The first height is 3 millimeters.
- Preferably, the cocking handle further includes an airflow groove. The airflow groove surrounds the outer surface of the cocking handle and is adjacent to the raised block. When the impact seat is fired to ignite gunpowder in the caseless projectile, a gas after combustion flows back to the airflow groove to prevent the gunpowder gas flow from impacting backward.
- Preferably, the airflow groove has a second width and a depth. Each of the second width and the depth is 2 millimeters.
- Preferably, the gun-type firing device further comprises a retaining frame. The retaining frame is disposed on another side of the gunstock. The retaining frame is configured to stand on a flat surface, thereby increasing the stability of the gun-type firing device.
- In an embodiment, the chamber area includes a raised member. The raised member is located on an inner wall of a reduced area of the chamber area. When the caseless projectile is loaded, the extractor is engaged with the groove and pushes the caseless projectile into the chamber area. After the extractor strikes the raised member, the extractor is disengaged from the groove, and the end of the cocking handle is against the impact seat. The caseless projectile is pushed into the chamber area by the cocking handle. When a firing pin of the gun bolt strikes the impact seat, the caseless projectile is shot out of the gun barrel from the muzzle area.
- Preferably, the gun-type firing device further comprises a safety device located on one side face of the gunstock. When a safety lever of the safety device is in a first position, the safety device is in an off state so that the gun-type firing device can be fired. When the safety lever is in a second position, the gun bolt can be pulled for loading and unloading, but the gun-type firing device cannot be fired. When the safety lever is in a third position, the gun-type firing device cannot be fired and the gun bolt is locked and unable to be pulled.

guide groove 1332 is located on the inner wall of thechamber area 133 at the other end of thegun barrel 13. Theguide groove 1332 corresponds in number to the raisedblock 1211. Four guide grooves are taken as an example in this embodiment. When the end of the cockinghandle 121 is pushed into thechamber area 133, the raisedblock 1211 and theguide groove 1332 cooperate with each other. In a preferred embodiment, theguide groove 1332 is an L-shaped guide groove, but not limited thereto, so that thegun bolt 12 locks and closes thechamber area 133 at one end of thegun barrel 13 to prevent the recoil force generated by firing thecaseless projectile 2. - The cocking handle 121 further includes an
airflow groove 1212. Theairflow groove 1212 surrounds the outer surface of the cockinghandle 121 and is adjacent to the raisedblock 1211. In the preferred embodiment, theairflow groove 1212 has a second width W2 and a depth D (as shown inFIG. 4 ). Each of the second width W2 and the depth D is 2 millimeters, but not limited thereto. - When the
impact seat 22 is fired to ignite the gunpowder in thecaseless projectile 2, the gas after combustion flows back to theairflow groove 1212 to prevent the gunpowder gas flow from impacting backward. - In addition, the
chamber area 133 further includes a raisedmember 1333. The raisedmember 1333 is located on the inner wall of a reducedarea 1334 of thechamber area 133. When thecaseless projectile 2 is loaded, theextractor 122 is engaged with thegroove 22 and pushes thecaseless projectile 2 into thechamber area 133. After theextractor 122 strikes the raisedmember 1333, theextractor 122 is disengaged from thegroove 22, and the end of the cockinghandle 121 is against theimpact seat 22. Thecaseless projectile 2 is pushed into thechamber area 133 by the cockinghandle 121. When afiring pin 123 of thegun bolt 12 strikes theimpact seat 22, thecaseless projectile 2 is shot out of thegun barrel 13 from themuzzle area 131. - When the
impact seat 22 is against one side of the cockinghandle 121 and theextractor 122 is engaged with thegroove 23, thecaseless projectile 2 and the cocking handle 121 perform thelinear displacement movement 9 for thecaseless projectile 2 to move out of thegun barrel 13. - Please refer to
FIG. 6 . In addition, in another embodiment, the gun-type firing device 1 further includes a retainingframe 14. The retainingframe 14 is arranged on the other side of thegunstock 11. The retainingframe 14 is configured to stand on a flat surface, thereby increasing the stability of the gun-type firing device 1. - Please refer to
FIG. 7 . In addition, in a further embodiment, the gun-type firing device 1 further includes asafety device 15. Thesafety device 15 is located on one side face of thegunstock 11, and thesafety device 15 is connected to thegun bolt 12. When asafety lever 151 of thesafety device 15 is in afirst position 81, thesafety device 15 is in an off state so that the gun-type firing device 1 can be fired. - When the
safety lever 151 is in asecond position 82, thegun bolt 12 can be pulled for loading and unloading, but the gun-type firing device 1 cannot be fired. - When the
safety lever 151 is in athird position 83, the gun-type firing device 1 cannot be fired and thegun bolt 12 is locked and unable to be pulled. - In summary, the advantages of the present invention are described below.
- 1. The gun barrel of the gun-type firing device does not have rifling. Thus, when the caseless projectile is fired, the friction between the caseless projectile and the rifling can be avoided. When the caseless projectile is shot out of the muzzle, the initial velocity is increased to achieve a longer range.
- 2. Through the design of the airflow groove, when the gun-type firing device fires the careless projectile, it can prevent the backlash of the gas generated by firing the caseless projectile, thereby reducing the recoil force.
- 3. Through the design of the protrusions, when the caseless projectile is pushed into the gun barrel, the protrusions scribe the outer surface of the caseless projectile to form a plurality of scribe lines, and the protrusions secure the caseless projectile in the gun barrel.
- Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
