Definitions

  • the present invention generally relates to a percussion and magazine revolving device of a toy projectile launcher, and more particularly to a percussion and magazine revolving device that causes a firing mechanism to launch toy projectiles when a trigger is pulled and at the same time automatically revolves a magazine by an angle to achieve an effect of launching projectiles in succession.
  • Toy guns that are used in survival games for shooting with BB bullets or paintballs are made so real and also exciting, making them widely popular and appealing to the general people.
  • the toy guns that are available in the market for shooting BB bullets or paintballs are often structured for shooting only BB bullets and paintballs in succession. This lowers the interesting and exciting of playing the game.
  • a projectile launcher that may simultaneously shoot a number of BB bullets or paintballs provides a strong and heavy fire and is thus more appealing to the game players.
  • One solution is to load a cartridge that contains a number of BB bullets or paintballs and a pressure accumulation structure of compressed air in a projectile launcher and then activate a trigger of the projectile launcher to launch the projectile cartridge so that the compressed air released from the pressure accumulation structure instantaneously project the BB bullets or the paintballs.
  • the structure of cartridge that is currently adopted is very complicated and further, launcher is made in a structure of single shot. This cannot satisfy the game players who place a strong demand for more advanced firearms.
  • US Patent No. 4,426,802 discloses a toy projectile launcher that comprises a magazine having cylindrical accommodation chambers to receive therein projectiles and a trigger that operates a percussion mechanism to sequentially fire the projectiles received in the magazine.
  • the present invention aims to provide a toy projectile launcher that comprises an improved percussion and magazine revolving device that allows successive launch or firing of the launcher by arranging a magazine advancement mechanism comprising a release plate operated by a drive bar and provides easy and convenient use and operation.
  • the primary objective of the present invention is to provide a percussion and magazine revolving device of a toy projectile launcher, which causes a percussion mechanism to launch toy projectiles when a trigger of the launcher is pulled and at the same time automatically revolves a magazine by an angle to achieve an effect of launching grenades in succession.
  • the present invention provides a toy projectile launcher as specified in the appended claims.
  • the percussion mechanism forms an elongate horizontal slot
  • the carrier seat comprises a constraint pin, wherein the constraint pin is received in the elongate horizontal slot, so that when the trigger is pulled, the percussion mechanism is caused to make a horizontal movement to activate a firing operation of the cartridges.
  • the present invention comprises a magazine 1, a trigger 2, and a percussion mechanism 3 coupled to the trigger 2.
  • the magazine 1 comprises a plurality of annularly arranged cylindrical accommodation chambers 11, of which a center is fit over a box 12.
  • the box 12 contains therein a power spring like elastic element and further, a movable positioning bar 121 is arranged at a center of the box 12 in such a way that the positioning bar 121 extends through a fixation disk 51 of the launcher 5 and coupled to a U-shaped pull bar 122.
  • the magazine 1 has an end having a circumference along which a plurality of holding pegs 13 is arranged in a spaced manner.
  • the box forms positioning slots 14 that are arranged in a radiating fashion and correspond to the cylindrical accommodation chambers 11. Attached to a top edge of the fixation disk 51 are a release plate seat 15, which forms a circular hole 151, and a release plate 16.
  • the release plate 16 is mounted to the release plate seat 15 by a mounting pivot 161 in a swinging manner and forms a circular hole 162.
  • the release plate has a bottom forming a pawl 163 and the pawl 163 has a top to which a spring 164 is mounted in such a way that an opposite end of the spring 164 is retained by a top edge of release plate seat 15.
  • the release plate 16 has a top edge that forms an operation lever 165 projecting beyond and thus exposed outside the release plate seat 15.
  • the magazine 1 after being fit over and fixed to the box 12, can be rotated out of the grenade launcher 5 to allow cartridges to be placed into the cylindrical accommodation chambers 11. And, then the magazine 1 can be rotated back on the positioning disk 52 of the launcher 5 so as to allow the positioning bar 121 to fit into a central hole 521 of the positioning disk 52 to get ready for firing.
  • the trigger 2 is mounted by a mounting pivot 21 to a carrier seat 4 so as to be rotatable for trigger pulling as being supported by the mounting pivot 21.
  • the trigger carries a push bar 22 thereon and has a rear end to which a spring 23 is attached so that after being pulled, the trigger is allowed to return to the original position by the spring force of the spring 23.
  • the percussion mechanism 3 is arranged on the carrier seat 4 and is pivoted to the trigger 2.
  • the percussion mechanism 3 forms an elongate horizontal slot 31.
  • the carrier seat 4 comprises a constraint pin 41 that is received in the elongate horizontal slot 31, so that the trigger 2, when being pulled, drives the percussion mechanism 3 to move in a horizontal direction.
  • the percussion mechanism comprises a striker bar 32 and a positioning tab 33 arranged at the front side of the percussion mechanism and a drive bar 34 is arranged at the top side of the percussion mechanism.
  • the drive bar 34 has a front end that forms a tapering tip
  • a percussion and magazine revolving device of the toy projectile launcher is formed and can be assembled to a launcher 5.
  • the cylindrical accommodation chambers 11 of the magazine 1 may receive and hold therein cartridges 6.
  • the release plate 16 pressed down by the spring 164 to have the pawl 163 engages and thus fixes one of the holding pegs 13 of the magazine 1.
  • the percussion mechanism 3 is caused to make a horizontal movement to have the positioning tab 33 fit into and fix the corresponding one of the positioning slots 14 and the striker bar 32 fires the grenade.
  • the drive bar 34 is driven into the circular hole 162 of the release plate 16 to cause the pawl 163 to raise upward, thereby allowing the magazine 1 to rotate by an angle for being ready to fire the cartridge 6 of the next cylindrical accommodation chamber and thus realizing successive firing of the cartridges 6.
  • the cartridge 6 comprises a front cap 61, a bullet chamber 62, a storage chamber 63, and an actuation rod assembly 64.
  • the bullet chamber 62 comprises a plurality of annularly arranged accommodation cylinders 621 for receiving therein BB bullets or paintballs 7.
  • the storage chamber 63 forms circumferential raised walls 631, 632.
  • the actuation rod assembly 64 is of a hollow structure, having a front end forming an air inlet 641 that comprises a check valve and a rear end forming an air outlet 642 and carrying annular gasket rings 643, 644.
  • the gasket rings 643, 644 are respectively set in engagement with the raised walls 631, 632 so as to hermetically enclose the storage chamber 63.
  • Compressed or pressurized air is fed through the air inlet 641 so that the compressed air is discharged from the air outlet 642 to accumulate in the storage chamber 63.
  • the actuation rod assembly 64 is moved forward to move the gasket rings 643 away from the raised walls 631, so that the compressed air inside the storage chamber 63 is released to instantaneously eject the BB bullets or the paintballs 7 received in the bullet chamber 62.
  • FIG 4A is a perspective view illustrating loading of cartridges according to the present invention
  • the U-shaped pull bar 122 is pulled frontward to separate the positioning bar 121 from the central hole 521 of the positioning disk 52 of the grenade launcher 5 so that the magazine 1 may then be allowed to turn outward to one side to expose the cylindrical accommodation chambers 11, wherein cartridges 6 are allowed to be put into the cylindrical accommodation chambers 11 of the magazine.
  • the magazine 1 is pushed backward to make the positioning bar 121 fit into the central hole 521 of the positioning disk 52 again, assuming a ready to fire condition.
  • FIGS. 5 and 5A are a side elevational view and a partial perspective view illustrating an un-fired condition of the present invention
  • the percussion mechanism 3 in a normal condition of the present invention, is set in a rearward position with the drive bar 34 on the top side thereof disengaging from the circular hole 162 of the release plate 16 so as to allow the pawl 163 to be depressed downward by the spring force of the spring 164 to engage and thus retain the holding pegs 13 in position.
  • FIG 6 which is a side elevational view illustrating a firing condition of the present invention, reference being also made to FIG 4 , as shown in these drawings.
  • a user pulls the trigger 2 to cause a horizontal movement of the percussion mechanism 3.
  • the positioning tab 33 is fit into the corresponding one of the positioning slots 14 to thereby retain the magazine 1 in position.
  • the striker bar 32 dries the actuation rod assembly 64 of the corresponding cartridge 6 to cause the gasket ring 643 to separate from the raised wall 631, thereby allowing the compressed air stored in the storage chamber 63 to be released and instantaneously eject the BB bullets or paintballs 7 contained in the bullet chamber 62.
  • FIGS. 6A and 7 are respectively a partial perspective view and a front view illustrating revolving of the magazine according to the present invention
  • the drive bar 34 is driven forward by the percussion mechanism 3 to engage the circular hole 162 of the release plate 16 arranged on the top side of the magazine 1 so as to cause the pawl 163 to raise upward and disengaging the pawl 163 from the holding pegs 13, whereby the magazine 1 is allowed to rotate, as being driven by the spring force of the box 12, by an angle, and afterwards, the spring 164 provides a depression spring force that causes the pawl 163 to move downward and engage one of the holding pegs 13 to get ready for firing the cartridge of the next cylindrical accommodation chamber 11 thereby realizing successive firing of the cartridges.
  • the spring 23 After the trigger 2 is released following the firing operation, the spring 23 returns the trigger back to the original position so that the percussion mechanism 3 is simultaneously pulled backward (as shown in the condition of FIG 5 ), whereby the force that drives the drive bar 34 disappears and the release plate 16 is caused to move downward by the depression of the spring 164. Since the drive bar 34 has a tapering front top, the release plate 16 applying a force thereto may cause the circular hole 162 to force the drive bar 34 back to the original position (as shown in the condition of FIG 5A ).
  • manual operation may be made to pull the operation lever 165 for causing the pawl 163 to raise upward and then the operation lever 165 is timely released to allow the magazine 1 to just rotate by a desired angle.
  • the percussion mechanism is combined with a rotatable the magazine, as well as retention by pawl realized in synchronization with the percussion mechanism, so as to form a percussion and magazine revolving device of top grenade launcher, whereby when the trigger is pulled, the grenade launcher may cause the percussion mechanism to launch a cartridge and also cause the magazine to rotate by an angle for achieving successive firing of cartridges.
