摘要： PURPOSE: To obtain a shot holding structure of a sport air gun with higher hitting accuracy. CONSTITUTION: It is so arranged to separate a shot packing 35 for holding a shot W and a nozzle packing 34 for preventing air leak from the perimeter of a nozzle 33 so that mutual interference such as deformation is eliminated between the nozzle packing 33 and the shot packing 35 while a nozzle guide part is provided between the nozzle packing 33 and the shot packing 35. This enables aligning of the center of the nozzle 33, the center of the shot packing 35 and the center of a barrel 31 thereby achieving a high hitting accuracy.

摘要： PROBLEM TO BE SOLVED: To stop supply of a compressed gas to a bullet side passage with a simple structure. SOLUTION: In a cylinder block 114, a loading sleeve 115 is disposed at a loading packing side 108 portion and a cylinder portion 116 is disposed at a gun rear end side portion. A bullet shooting ventilation hole 117 is formed in the loading sleeve 115, while a blow back ventilation hole 119 is formed in the cylinder portion 116. In an air supply passage 126, a bullet side passage 127 which is opened such that it faces the bullet shooting ventilation hole 117 of the loading cylinder 115 in an opposed manner and a cylinder side passage 128 which faces the blow back ventilation hole 119 are formed in a bifurcated form. A changeover valve 134 is provided at the bifurcated position of the air supply passage 126 and such valve 134 is constituted such that when the gas pressure of a compressed gas which enters the bullet side passage 127 becomes a negative pressure relative to the gas pressure of a compressed gas which enters the cylinder side passage 128, the changeover valve 134 is rotated with one end thereof used as a rotating end so as to close the bullet side passage 127.

摘要： PROBLEM TO BE SOLVED: To simplify a structure in a slide and stabilize compressed gas supply time, by providing a compressed gas supply changeover valve on a grip part not in the slide, coupled with an opening/closing valve. SOLUTION: Upon shooting a user pulls a trigger 51 in the direction of A in the state where a bullet W is loaded, and a hammer 41 is engaged and held with a shear 45. Thereupon, a trigger 52 is moved in the direction of the muzzle B, a pushing part 53 pushes a pushed part 48, the shear 45 is rotated around a shaft 46 in the direction of the muzzle B, and a pawl part 47 is disengaged from a shear stop part 44 for release of the engagement. The hammer 41 is rotated in the direction of time muzzle B with energizing force of a hammer spring 43 to push a valve rod 32 of an opening/closing valve 29 and hence open an exhaust hole 25. Thereupon, compressed gas from a compressed gas containing part 21 flows out from the exhaust hole 25 through the opening/ closing valve 29 to a changeover valve air chamber 26, and the compressed gas flows out energetically from bullet shooting air supply hole 27 to a bullet shooting vent hole 17 to shoot a loaded bullet.

摘要： PURPOSE:To hold a large elastic force at the time of accumulating the pressure of a piston and to manually continuously use it even if it is stopped during using by motor driving. CONSTITUTION:In the case of using by motor driving, the rotating motion of a crank disc 91 is converted to the sliding motion (linear motion) of a converter 12 via a connecting arm 10 and a rocking arm 11. A pressure-accumulated piston 15 is held by a motor driven shear rod 131 and a motor driven shear 132. A bullet A is shot by the elastic force of a piston spring 151. In the case of using manually, the piston 15 is moved by a manual coking handle bar 16, and held by a manual cocking shear 17 and a manual cocking shear rod 18. When the using by the motor driving is stopped, the bar 16 is moved, and manually moved from the stopped place.

摘要： PURPOSE: To effectively utilize a gas pressure and to increase a bullet firing speed, by engaging a bullet controller being mounted in an insertable manner into a bullet control hole at the inner rear portion of an engine main body into a longitudinal air-feeding pipe being provided at the center of a bullet loading control hole from the rear edge of the engine main body, and providing the inner and outer diameters of the bullet controller airtightly. CONSTITUTION: When a lock lever 32 is operated and set to a single firing side, the engagement among a lock claw 38 being provided at a gear-lock lever 24, the lock lever 32, and a related projection 37 is released, the gear-lock lever 24 rotates when a trigger 22 is pulled due to the operation of an urging spring, and a gear-lock claw 29 is rotated into the rear passage of a gear-lock projection 10 of a bullet controller 6. Then, a gas switching valve 14 is opened by a trigger 22 and a gas is discharged to the front of a bullet loading control hole 3 through a longitudinal air-feeding pipe 5. Therefore, the bullet controller 6 is allowed to retreat due to a gas pressure and the gear-lock projection 10 at a rear edge is gear-locked to the gear-lock lever 24. When a firing actuation bullet guiding pipe 11 advances due to the operation and an O-ring actuation valve 12 moves to a front edge large-diameter bullet firing hole 2, the diameter is enlarged, and a bullet 39 being supported airtightly until that point pushes and opens the actuation valve 12 and passes the inner diameter and then is fired at a time due to a firing gas pressure. In a continuous automatic firing, the lock lever 32 is set to an automatic firing side.

摘要： PROBLEM TO BE SOLVED: To provide an automatic air sports gun which can continuously shoot bullets without influence at the position of a valve by the bullet. SOLUTION: A cylinder block side vent hole 18a is blocked by a blocking part 24 at the normal time by being urged by a valve spring 22 in a direction A, and a bullet loading port side vent hole 18b is opened by an intermediate part 23. When compressed gas to be introduced from a suction and exhaust port 20 provided at the side of a second gas chamber 19 is drawn to a muzzle B and negative pressure is generated in a second gas chamber 19, the hole 18a is opened by the part 24 and the hole 18b is closed by the part 23 by a valve 21. The valve 21 is provided in the chamber 19 of a nozzle block 17. A trigger 44 is maintained in the state drawn in the direction A, and hence the holes 18a and 18b of the nozzle 21 are alternately opened and closed to continuously shoot bullets.

摘要： PROBLEM TO BE SOLVED: To provide an automatic air sports gun capable of effectively utilizing compressive gas pressure and reduced in size a piston block. SOLUTION: A switching valve 34 and an opening/closing valve 30 are disposed under a cylinder block. The valve 34 is installed so that a blocking portion 35 of the valve 34 is exposed within a switching valve air chamber 21 and only a rod 36 is disposed in the chamber 21. When a compressive gas is supplied to a bullet shooting vent hole 19 side through the chamber 21, the portion 35 opens a bullet shooting air supply port 22 to the state that a flow of the gas to the port 22 is not disturbed. When the gas is supplied to a blow- back vent hole 20, the portion 35 opens a blow-back gas supply hole 23. Then, supply of the gas in the chamber 21 is disturbed only by a rod 36 of the valve 30.
