- The present disclosure relates to the field of competitive equipment and, in particularly, to a soft projectile launcher.
- Nowadays, projectile launchers are mainly used for games and training, and the projectiles used are generally hard projectiles, such as BB projectiles or steel ball projectiles, which have great lethality under the action of the launcher, and cause great danger to people or animals. In some scenarios, such as during competitions, the risk of injury to people or animals caused by the launcher will increase if hard projectiles are used. The use of soft projectiles is an ideal choice.
- However, the current launcher normally launches the wrongly loaded hard projectiles. For this reason, there is a need to propose a launcher with safety protection, ensuring normal launching of soft projectiles while preventing hard projectiles from being launched, to avoid the hard projectiles causing injury to people or animals.
- In accordance with the disclosure, there is provided a soft projectile launcher including a launching tube, a projectile entry tube, and a power assembly. The launching tube includes a power channel, a projectile loading channel, and a projectile exit channel connected in sequence. The projectile entry tube includes a projectile entry channel connected to the projectile loading channel and configured to provide a soft projectile to the projectile loading channel. The power assembly connected to a free end of the power channel and configured to provide power for launching the soft projectile. At least a part of at least one of the projectile entry channel, the projectile loading channel, or the projectile exit channel includes an elliptical channel.

At least a part of the projectile loading channel and/or the projectile exit channel is an elliptical channel. - In some embodiments, the power channel, the projectile loading channel, and the projectile exit channel are sequentially connected, which can be partially arranged non-coaxially. The
power assembly 30 is connected to the power channel to launch the soft projectile in the projectile loading channel along the projectile exit channel. For example, the projectile loading channel is arranged coaxially with the projectile exit channel, but is arranged non-coaxially with the power channel. - In some embodiments, the power channel is arranged non-coaxially with the projectile loading channel, and the
power assembly 30 is connected to the power channel to launch the soft projectile in the projectile loading channel along the projectile exit channel. - A part or all of the projectile loading channel and/or the projectile exit channel may be an elliptical channel.
- In a manufacturing process, the
power section 11, theprojectile loading section 12, and theprojectile exit section 13 can be formed as an integral part and can be casted in a mold to form thelaunch tube 10. In some other embodiments, thepower section 11, theprojectile loading section 12, and theprojectile exit section 13 can be separate parts and be connected to form thelaunch tube 10. - The
projectile entry tube 20 includes a projectile entry channel, which is connected to the projectile loading channel to provide the soft projectile for the projectile loading channel. In some embodiments, the inside of theprojectile entry tube 20 is the projectile entry channel. Theprojectile entry tube 20 and thelaunch tube 10 are arranged perpendicular to each other, and the projectile entry channel and the projectile loading channel are arranged perpendicular to each other. In some embodiments, the projectile entry channel and the projectile loading channel may be not perpendicular to each other, and the projectile entry channel is configured to load the soft projectile into the projectile loading channel. In a manufacturing process, theprojectile entry tube 20, thepower section 11, theprojectile loading section 12, and theprojectile exit section 13 can be formed as an integral part and can be casted in a mold to form a T-shaped structure. In some other embodiments, theprojectile entry tube 20, thepower section 11, theprojectile loading section 12, and theprojectile exit section 13 can be separate parts and be connected to form a T-shaped structure. - In the present disclosure, the projectile entry channel, the projectile loading channel, or the projectile exit channel can be configured to only allow a single soft projectile to pass through, and not allow two or more soft projectiles to pass through side by side.
- When the soft projectile enters the projectile loading channel via the projectile entry channel, the soft projectile may be elastically deformed in the projectile loading channel or the projectile exit channel, especially in the elliptical channel, to get stuck in the channel and close contacted to the wall of the channel. The
power assembly 30 provides power acting on the soft projectile in the channel to launch the soft projectile smoothly along the projectile exit channel, thereby implementing the launching process. - In the present disclosure, the soft projectile in the projectile loading channel is launched along the projectile exit channel by the
power assembly 30. To ensure that the soft projectile in the projectile loading channel can be smoothly launched along the projectile exit channel, the projectile loading channel and the projectile exit channel are smoothly connected and arranged in a straight line and coaxially, or the projectile loading channel and the projectile exit channel are arranged in a smooth curve. The projectile loading channel and the projectile exit channel are smoothly connected to reduce the resistance at the boundary between the two, thereby ensuring that the soft projectile is launched while fully utilizing the power from thepower assembly 30 to achieve a better launch effect. - In the present disclosure, the
power assembly 30 is used to provide power to launch the soft projectile in the projectile loading channel. - In some embodiments, the
power assembly 30 includes acompression chamber 31 and acompression piston 32. Thecompression piston 32 moves along the inside of thecompression chamber 31, and is connected to the inner wall of thecompression chamber 31 in an airtight and sliding fit. Thecompression chamber 31 is enclosed by atube wall 311, and thetube wall 311 is mounted on thehousing 60. One end of thecompression chamber 31 opposite to thecompression piston 32 is airtightly connected to the power channel to provide compressed air for the power channel. - In some embodiments, as shown in
FIG. 2 , one end of thecompression piston 32 is connected to thehousing 60 via acompression spring 33. The spring force of thecompression spring 33 acts on thecompression piston 32, and thecompression piston 32 rapidly moves along the inside of thecompression chamber 31. The air in thecompression chamber 31 is rapidly compressed under the squeezing action of thecompression piston 32, and the compressed air enters the power channel and pushes the soft projectile in the projectile loading channel to launch the soft projectile. - The soft projectile launcher of the present disclosure further includes an
extension tube 34. Theextension tube 34 includes an extension channel. One end of thecompression chamber 31 opposite to thecompression piston 32 is airtightly connected to one end of the extension channel, and the other end of the extension channel is airtightly connected to the power channel. Further, theextension tube 34 extends into the projectile loading channel, the nozzle of the extension channel extends into the projectile loading channel, and the nozzle of the extension channel can be in close contact with the curved surface of the soft projectile in the projectile loading channel. Anintake clearance 341 is formed at the edge of the nozzle of the extension channel in the projectile loading channel. - In some embodiments, the
compression chamber 31 is airtightly connected to the power channel via theextension tube 34, and the compressed air generated in thecompression chamber 31 enters the power channel via theextension tube 34, which is used to provide power for launching the soft projectile. Where, thecompression chamber 31 is enclosed by thetube wall 311 to form a cylindrical shape, and is airtight and slidingly fitted with thecompression piston 32. In a manufacturing process, the compressed air inside thecompression chamber 31 is guided into the power channel by using theextension tube 34 according to the actual situation. Where, the nozzle of the extension channel of theextension tube 34 can directly extend into the projectile loading channel, and the nozzle of the extension channel can be close contact to the curved surface of the soft projectile in the projectile loading channel. Thus, the compressed air directly aiming at the soft projectile to launch the soft projectile along the projectile exit channel, and to achieve a better launch effect. - In some embodiments, the nozzle of the extension channel may not be close contact to the curved surface of the soft projectile in the projectile loading channel, and external air can enter the extension channel by the projectile exit channel and/or the projectile entry channel, and can enter the
compression chamber 31. - In some embodiments, external air can enter the extension channel and the
compression chamber 31 via a side of thetube wall 311 that is close to thecompression piston 32. An air inlet gap (not shown) is provided at the opening of thetube wall 311. When thecompression piston 32 moves away from the side of theextension tube 34, external air can enter thecompression chamber 31 via the air inlet gap. When thecompression piston 32 compresses towards theextension tube 34, thecompression piston 32 is airtightly and slidingly fitted with the wall, i.e., thetube wall 311, of thecompression chamber 31, to compress the air in thecompression chamber 31. - Further, in some embodiments, an intake clearance 341 (as shown in
FIG. 4 ) is provided at the edge of the nozzle of the extension channel. When thecompression piston 32 moves away from the side of theextension tube 34 under the action of external power, external air can enter thecompression chamber 31 via theintake clearance 341. When the external power is released, thecompression piston 32 can rapidly compress the air in thecompression chamber 31 under the action of thecompression spring 33, and the compressed air can enter the power channel via the extension channel and act on the soft projectile to launch the soft projectile. The external power in above embodiments may be electric power, and may be transmitted via a gear structure to enable thecompression piston 32 to move away from the side of theextension tube 34. - In some embodiments, compressed air is used as the power source, and acts on the soft projectile in the projectile loading channel to launch the soft projectile along the projectile exit channel. The soft projectile elastically deforms in the projectile loading channel or the projectile exit channel, especially in the elliptical channel, gets stuck in the channel, and airtightly fits with the wall of the channel. Then the compressed air can effectively act on the soft projectile for a long time to cause the soft projectile to be launched along the projectile exit channel with greater kinetic energy, thereby achieving farther and better launch effect.
- In particular, when the projectile loading channel and/or the projectile exit channel is an elliptical channel, the soft projectile can deform elastically in the projectile loading channel or the projectile exit channel, and can be airtightly fitted with the wall of the channel with stronger airtightness, thereby causing the soft projectile launcher to achieve a better launch effect.
- In some embodiments, the
power assembly 30 may also be a striking mechanism. The striking mechanism directly strikes the soft projectile in the projectile loading channel to launch the soft projectile along the projectile exit channel. - In some embodiments, the soft projectile launcher further includes a
projectile loading mechanism 40, and amagazine 50, which are mounted on thehousing 60. Theprojectile loading mechanism 40 includes arefill 41, and adial 42. Therefill 41 and themagazine 50 are enclosed to form a projectile accommodation space 51. The projectile accommodation space 51 is used for storing the soft projectile. Thedial 42 of theprojectile loading mechanism 40 is used to load the soft projectile in the projectile accommodation space 51 into the projectile entry channel to cause the soft projectile to enter the projectile loading channel via the projectile entry channel. - In some embodiments, as shown in
FIG. 1 andFIG. 2 , themagazine 50 is mounted at the upper part of theprojectile loading mechanism 40. Therefill 41 of theprojectile loading mechanism 40 is used as a part of the bottom of themagazine 50, and encloses themagazine 50 as a projectile accommodation space 51. The soft projectiles in the projectile accommodation space 51 are gathered at therefill 41. - The
dial 42 is rotatably mounted at the bottom of therefill 41. Thedial 42 has at least one projectile movinggap 421 on the side, aprojectile inlet 411 is formed at a position at the bottom of therefill 41 corresponding to one of the at least one projectile movinggap 421, and theprojectile inlet 411 is connected with the free end of the projectile entry channel. The size of the projectile movinggap 421 is equivalent to the size of the soft projectile. The bottom of thedial 42 extends outward to form apusher 422. Thedial 42 can be rotated by rotating thepusher 422. - Further, the wall surface of the projectile moving
gap 421 is inclined, and the inclined wall surface of the projectile movinggap 421 can squeeze the soft projectile into theprojectile inlet 411 when thedial 42 rotates. - In some embodiments, the
magazine 50 and theprojectile loading mechanism 40 are mounted on thehousing 60. The soft projectiles are gathered on therefill 41 and pushed into theprojectile inlet 411 by the action of thedial 42. Further, when the projectile entry channel is an elliptical channel, the soft projectile cannot easily enter the projectile entry channel. Thus, the wall surface of the projectile movinggap 421 is inclined. Thepusher 422 drives thedial 42 to rotate, the inclined wall of the projectile movinggap 421 squeezes the soft projectile downwards, and the soft projectile is squeezed into the projectile entry channel at theprojectile inlet 411, to realize the loading of the soft projectile. Thedial 42 is rotated to prevent the soft projectiles from gathering and being stuck, which facilitates the smooth entry of the soft projectiles into the projectile entry channel. - Further, in some embodiments, the projectile exit channel includes a first projectile exit channel and a second projectile exit channel, and the first projectile exit channel is airtightly connected with the projectile loading channel. The first projectile exit channel and the second projectile exit channel are airtightly connected via nested tube fitting.
- In some embodiments, as shown in
FIG. 3 andFIG. 4 , theprojectile exit section 13 includes a firstprojectile exit tube 131 and a secondprojectile exit tube 132. The inside of the firstprojectile exit tube 131 is the first projectile exit channel, and the inside of the secondprojectile exit tube 132 is the second projectile exit channel. The firstprojectile exit tube 131 is connected to theprojectile loading section 12. In some embodiments, the firstprojectile exit tube 131 and theprojectile loading section 12 are formed as an integral part, thereby causing the first projectile exit channel to be airtightly connected with the projectile loading channel. The firstprojectile exit tube 131 and the secondprojectile exit tube 132 are nested and airtightly connected. In some embodiments, an airtight gasket is provided between the firstprojectile exit tube 131 and the secondprojectile exit tube 132 to achieve an airtight connection effect. In some embodiments, the firstprojectile exit tube 131 and the secondprojectile exit tube 132 can be sealed by welding, or integrally formed. - In some embodiments, the projectile exit channel is divided into the first projectile exit channel and the second projectile exit channel, which can extend the moving distance of the soft projectile along the channel. In a manufacturing process, the
projectile entry tube 20, thepower section 11, theprojectile loading section 12, and the firstprojectile exit tube 131 can be integrally formed. The secondprojectile exit tube 132 is connected to the free end of the firstprojectile exit tube 131 to extend the moving distance of the soft projectile along the channel, thereby enhancing the launch effect. - The shape and the size of the first projectile exit channel of the first
projectile exit tube 131 and the second projectile exit channel of the secondprojectile exit tube 132 can have various combinations. For example, the first projectile exit channel can be a round or an elliptical channel, and the second projectile exit channel can be a round or an elliptical channel. - In some embodiments, the first projectile exit channel is an elliptical channel, and the shape and the size of the second projectile exit channel are the same as those of the first projectile exit channel.
- In some embodiments, compressed air is used as a power source. When the projectile exit channel is an elliptical channel, and the moving distance of the soft projectile along the elliptical channel is extended, the soft projectile can be airtightly fitted to the wall of the channel due to the elastic deformation of the projectile. The airtightness is strong, and the compressed air then has a longer action time on the soft projectile, that is, the compressed air has a greater impulse on the soft projectile, thereby causing the launched soft projectile to have greater kinetic energy to achieve a longer range and better launch effect.
- Further, in some embodiments, to prevent a hard projectile from being normally launched in the soft projectile launcher, at least a part of the projectile entry channel is an elliptical channel together with the projectile loading channel and the projectile exit channel, to prevent the hard projectile from being normally launched. The hard projectile cannot enter the projectile loading channel via the elliptical channel of the projectile entry channel. Further, even if the hard projectile enters the projectile loading channel via the projectile entry channel, when the projectile loading channel or the exit channel is an elliptical channel, or the channel inside the
launch tube 10 does not match the hard projectile, the hard projectile cannot be launched normally in the channel. - In the technical solution of the present disclosure, at least a part of the projectile entry channel, the projectile loading channel, and/or the projectile exit channel is configured as an elliptical channel. As such, soft projectiles are ensured to be launched normally, while hard projectiles are prevented from being launched normally.
- It is intended that the above embodiments be considered as examples only and not to limit the scope of the present disclosure. Other embodiments of the disclosure including any changes, modifications, replacements, combination, and simplification by the above-mentioned embodiments, and any other changes, modifications, substitutions, and combinations without departing from the spirit and principle of the disclosure should be considered as equivalent replacement methods, which are all within the scope of the disclosure.
