Definitions

  • the present invention relates to a toy gun, in which the shooting of bullets charged in a loading chamber and the automatic supply of the loading chamber with the bullets are caused by the action of a gas pressure and, more particularly, in which the bullets to be charged in the loading chamber and shot are exemplified by paint containing bullets for discharging paint when crushed.
  • the toy gun in which a bullet is short from a barrel in accordance with the operation of a trigger and in which a slider arranged along the barrel is moved for supplying a next bullet
  • a toy gun in which the shooting of a bullet charged in a loading chamber disposed at the back of the barrel is done by using a gas pressure and in which the automatic supply of a bullet to the loading chamber by the movement of the slider is also done by using the gas pressure.
  • the grip is provided with a magazine for holding a plurality of bullets, and an accumulation chamber for reserving gas.
  • the gas pressure from the accumulation chamber is further used to move the slider backward and then forward in the direction along the barrel, so that the bullets held in the magazine disposed in the grip can be supplied to the emptied loading chamber and shot automatically.
  • the gas to be reserved in the accumulation chamber is exemplified by a liquefied gas under a low pressure
  • the bullet to be charged in the loading chamber is a sham one called the "BB bullet" made of plastics and having a relatively small diameter such as about 6 mm.
  • a toy gun which uses a paint containing bullet (as will be called the "paint bullet") having a relatively large diameter exceeding 10 mm, such as about 17 mm and made easily crushable to discharge the paint (for example, as referred to the non-patentpublication: "Monthly MagazineeGun, October", issued on October 1, 1992 by Kokusai Shuppan Kabushiki Gaisha, pp. 66 to 75).
  • a gas tank charged with carbonate gas (i.e. , CO 2 gas) under a high pressure is arranged in the frame, and amagazine called the "loader" capable of holding a plurality of paint bullets is so mounted in the rear portion of the barrel with an upward protrusion through a feeding port.
  • CO 2 gas carbonate gas
  • a movable member formed by combining an upper bolt and a lower bolt
  • a valve mechanism formed by arranging an exhaust valve movably in an air chamber formed by a cylinder member.
  • the valve mechanism is provided with first and second gas passages and a connection gas passage for connecting those gas passages.
  • the movable member When the trigger is pulled to shoot the paint bullet charged in the rear portion of the barrel, moreover, the movable member is advanced by the biasing force of a spring member to act on the movable member, thereby to provide the communication between the first gas passage formed in the valve mechanism and the barrel and to move the exhaust valve from the position, at which the gas pressure from the gas tank is not introduced into the connection gas passage, to the position, at which the gas pressure from the gas tank is introduced into the connection gas passage.
  • the gas pressure from the gas tank flows into both the first and second gas passages through the connection gas passage.
  • the gas pressure having entered the first gas passage is guided into the barrel so that it is used for shooting the paint bullet.
  • the movable member which is caused when advanced to take the position for closing a feeding port from the barrel, is retracted by the raised gas pressure coming from the gas tank and acting through the second gas passage formed in the valve mechanism.

It is accordingly desired that the paint bullet charged in the loading chamber is reliably shot even by using the low-pressure gas. In the prior art, however, there has not been found the toy gun, which can satisfy those desired.

  • the flow of the gas from the gas chamber 8 into the gas inlet passage 34 is stopped.
  • the piston portion 35b of the control valve 35 having closed the gas outlet passage 34 abuts against the lower end of the lock member 38 having reached the lower position, from the upper side, thereby to keep the lock member 38 at the lower position.
  • the sealing property of the pressure chamber 80 by the annular seal member 56 is lost so that the gas residing in the pressure chamber 80 and the gas residing in the second gas passage 52 are released to the atmosphere through a clearance 81 formed between the cylindrical portion 12 and that portion of the gas passage forming portion 55, which forms the second gas passage 52.

  • the retraction of the gas flow control mechanism 50 by the biasing force of the coil spring 47 is stopped, as shown in Fig. 8, by the abutment of the rear end of the gas passage forming portion 55 against the piston plunger 20 taking the forward position.
  • the opening of the second gas passage 52 in the gas passage forming portion 55 is closed by the second pressure receiving portion 22, and that portion of the gas passage forming portion 55, which forms the first gas passage 51, is positioned at the back of the loading chamber 4, thereby to cause the bullet discharge port 5a of the magazine 5 to communicate with the inlet position 4a in the loading chamber 4.
  • the paint bullet P drops from the magazine 5 into the inlet position 4a in the loading chamber 4.
  • the paint bullet P having dropped to the inlet position 4a is positioned by the current plate portion 57 in the movable valve 60 abutting the back of the paint bullet P and by the paired small protrusions 32.
  • the advance of the moving member 16 by the biasing force of the coil spring 43 is stopped, as shown in Fig. 8, when the moving member 16 is regulated in position by the connecting member 67 after the engaging step 18 formed on the moving member 16 abutted against the rear abutment portion 67b of the connection member 67 from the rear side and advanced the connection member 67 within the range defined by the slot 67c and the pin 70.
  • the moving member 16 is regulated in position by the connection member 67, the movable member 10 is placed at the reference position which is at the back of the upper end portion of the lock member 38 taking the lower position, and the moving member 16 is placed at the initial position, in which its front end portion is slightly inserted into the bottomed cylindrical guide portion 44.

  • the second gas passage 52 in the gas flow control mechanism 50 is closed so that the gas pressure from the gas chamber 8 leading to the gas outlet passage 34 is not guided to the secondgas passage 52. Therefore, there is reliably avoided the situation, in which the gas pressure to be used for shooting the paint bullet P from the loading chamber 4 might otherwise be partially lost.
  • the gas pressure from the gas chamber 8 is effectively applied to the paint bullet P charged in the loading chamber 4 so that the paint bullet P can be reliably shot from the loading chamber 4 even in case the gas to be supplied from the gas chamber 8 to the gas outlet passage 34 is exemplified by a low-pressure gas such as a liquefied gas.

  • the second gas passage is changed from the closed state to the open state.
  • the gas as fed to the gas outlet passage by the movement of the movable member in the first direction to the loading chamber, acts the pressure receiving portion formed on the movable member through the second gas passage so that the movable member is moved in the second direction apart from the loading chamber, to take the state for making preparations for supplying the loading chamber with the bullet.
  • the second gas passage is closed to prevent the situation, in which the gas flows into the second gas passage.
  • the situation, in which the gas pressure to be used for shooting the bullet charged in the loading chamber is partially lost is reliably avoided to use the gas supplied to the gas outlet passage, effectively for shooting the bullet.
