Cartridge box of pneumatic toy gun

A cartridge box of a pneumatic toy gun includes an air lock system and a struck element disposed on the upper inside the case of the cartridge box, and further includes a control system having a pushing rod and a resisting rod, wherein a front end of the pushing rod extends into the bullet-out passage disposed inside the case. When there is no bullet in the bullet-out passage, a lateral end of the stripping rod resists upward against the front end of the pushing rod to make the back end of the resisting rod moving downward to resist against the resisting portion of the struck element, resulting that the struck element cannot push the air lock system forward. Thereby, when there is no bullet in the cartridge box, even if the trigger is pressed, the air lock system cannot moves to push the bolt. Hence, firing without bullet will be avoided and the effects of the simulate gun would be achieved. The cartridge box further has a turning system having a turning portion with a cam portion, which is turned upward to resist against the resisting rod, resulting that the resisting rod moves away from the resisting portion of the struck element. Thereby the bolt can be pushed to make a fire without bullet.

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a cartridge box of a pneumatic toy gun, and more particularly to a pneumatic toy gun, wherein when its trigger is pressed and its cartridge box contains no bullet, the bolt could be controlled by a user to be selectively moved forth and back.

2. Description of Related Arts

The driving principle of the pneumatic toy gun is different from that of the electrical toy gun. Referring toFIG. 1, when the trigger10of the pneumatic toy gun is pressed, the hammer20drives the firing pin30to move forth, which impact the struck element40disposed on the upper portion inside the cartridge box. Then the struck element40pushes the air lock system50forward to open the air inlet601of the plunger60, thereby the inner gas of the cartridge box (a) flows into the plunger60to make the bolt70to move back as shown inFIG. 2. When the bolt70moves back, the hammer20is forced to return back. Meanwhile, the firing pin30also returns back to force the air lock system50to move back, thereby the air inlet601of the plunger60is closed to stop the flowing of the gas. Due to the spring701, the bolt70moves forth, and then the hammer20drives the firing pin30to move forth again.

The principles of the gas flowing and the firing structures have been mentioned above. If repeat the movements mentioned above, the gun could be fired continuously.

However, in case the bullets in the cartridge box (a) have been used up and the trigger10is still pressed, the hammer20, the firing pin30, the struck element40, the air lock system50, and the plunger60will still keep moving to fire without bullets, instead of stopping. In addition, only when there is no bullet shot out, the user would know there is no bullet in the gun. Hence, when there is no bullet, the continuous movements mentioned above make no sense, and also waste the gas in the cartridge box (a) and reduce the effective firing of the gas, both of which cause damages to the elements. Hence, it is necessary to improve the conventional pneumatic toy gun.

SUMMARY OF THE PRESENT INVENTION

It will be appreciated that the present invention provides a control system, with which the movement of the air lock system could be stopped when there is no bullet, thereby the defects of the conventional pneumatic toy gun, such as when there is no bullet, the gas will still flow to cause the waste of gas and the damages to the elements, could be overcome. Besides, considering some users enjoy firing without bullets, the present invention also provides a system for the users to choose to fire without bullet or not, thereby the selectable functions of the present invention have been improved.

The present invention provides a cartridge box of a pneumatic toy gun, which air lock system could be chosen to be moved forth or not when there is no bullet. The cartridge box comprises a case and a bullet-out passage disposed on an inner side of the case, wherein an elastic element and a stripping rod are disposed inside the bullet-out passage. The elastic element is disposed under the stripping rod, which further has a lateral end. The case further comprises an air lock system and a struck element on the upper inside, wherein the air lock system is disposed in front of the struck element. The struck element is struck by the firing pin of the pneumatic toy gun to push the air lock system moving forward.

The improvement includes that the case further has a slot having a first position and a second position. The struck element has a resisting portion. An upper inside of the case further has a control system which comprises a pushing rod and a resisting rod.

The pushing rod has a front end portion, a middle end portion and a back end portion, wherein the front end portion extends into the bullet-out passage. The resisting rod has a front end and a back end, wherein the front end of the resisting rod is pivotally jointed with the middle end portion of the pushing rod. The back end of the resisting rod has a locking block, which extrudes out of the slot and is located in the first position. If there is no bullet, the lateral end of the stripping rod resists upward against the front end portion of the pushing rod, and then the back end portion of the pushing rod presses downward on the resisting rod to make the back end of the resisting rod move downward to resist against the resisting portion of the struck element. Thereby, the struck element cannot push the air lock system forward to stop the movement of the air lock system when needed, and thus the bolt will not move forth and back. At this time, the locking block is moved downward to the second position.

In addition, the resisting rod further has an upper locating portion and a lower locating portion, both of which are disposed on the back edge of the back end. A locating system is disposed in the case and behind the back end. The locating system has an elastic element disposed on the back to provide a forward elastic force to the locating system. Thereby, when the locking block of the back end of the resisting rod is moved to the first position, the locating system is elastically resisted against the lower locating portion of the resisting rod, and thus when the locking block of the back end of the resisting rod is moved to the second position, the locating system is resisted against the upper locating portion of the resisting rod. As a result, the locating will achieve.

Moreover, the case further has a through hole disposed on the side and a turning system disposed in the through hole. The turning system at least has a hole portion and a turning portion with a cam portion disposed under the resisting rod, wherein the hole portion is turning along with the turning portion. The back end of the resisting rod is moved downward to resist against the resisting portion of the struck element. At this time, the hole portion could be turned to make the turning portion turn along with the hole portion, and then the cam portion of the turning portion will be turned upward to resist against the resisting rod. That causes the back end of the resisting rod to move away from the resisting portion of the struck element, resulting that the air lock system could still be pushed when firing. Thereby, the user could choose to make a fire without bullet. Furthermore, the hole portion has a marking portion, and the through hole has a first indicating portion and a second indicating portion on the outside edge. When it is marked by the marking portion, both of which respectively indicate the situations before and after the cam portion is resisted against the resisting rod. Thereby, the user could know exactly what the structure and the function at that time.

Hence, the present invention provides a control system arranged to accomplish that, when there is no bullet in the pneumatic toy gun, the air lock system cannot be pushed forward and the bolt of the gun cannot move. Thereby, the momentum of the gas will not be wasted and the elements will not run idle to cause damages. Hence, the effects of the simulate gun can be achieved. Furthermore, the turning system is arranged for the users to choose to fire with or without bullets.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIG. 3, a cartridge box A of a pneumatic toy gun according to a preferred embodiment of the present invention is illustrated, which is capable of being used with an AK-type pneumatic toy gun, as well as the pneumatic toy guns showed inFIG. 1andFIG. 2, wherein the operational principle of which will not be detailed described here. Instead, the cartridge box A will be introduced in detail.

Referring toFIG. 4, the cartridge box A comprises a case A1, a bullet-out passage A2disposed on an inner side of the case A1, an elastic element A3and a stripping rod A4, wherein both of the elastic element A3and the stripping rod A4are disposed inside the bullet-out passage A2. The elastic element A3is disposed under the stripping rod A4to provide an upwards elastic force to the stripping rod A4which further has a lateral end A41.

Referring toFIG. 5, the case A1further comprises an air lock system A5and a struck element A6on the upper inside, wherein the air lock system A5is disposed in front of the struck element A6. Referring toFIG. 4, the struck element A6is struck by the firing pin A7of the pneumatic toy gun to push the air lock system A5moving forward.

Referring toFIG. 5, the case A1further has a slot A8having a first position A81and a second position A82. The struck element A6has a resisting portion A61. The upper inside of the case A1further has a control system B which comprises a pushing rod1and a resisting rod2.

Referring toFIG. 4, the pushing rod1has a front end portion11, a middle end portion12and a back end portion13, wherein the front end portion11extends into the bullet-out passage A2. The resisting rod2has a front end21and a back end22, wherein the front end21of the resisting rod2is pivotally jointed with the middle end portion12of the pushing rod1to further pivotally locate on the case A1. Referring toFIG. 6andFIG. 7, the back end22of the resisting rod2has a locking block23, which extrudes out of the slot A8and moves between the first position A81and the second position A82. As shown inFIG. 6, if the locking block23is moved to the first position A81, it indicates that there are bullets C in the bullet-out passage A2as shown inFIG. 4. Referring toFIG. 8, if there is no bullet C, the lateral end A41of the stripping rod A4resists upward against the front end portion11of the pushing rod1, and then the back end portion12of the pushing rod1presses downward on the resisting rod2to make the back end22of the resisting rod2moving downward to resist against the resisting portion A61of the struck element A6. Thereby, even if a fire has been made, the struck element A6cannot move forward due to being resisted by the back end22of the resisting rod2. That means the struck element A6cannot push the air lock system A5, thereby the bolt will not move forth and back. At this time, the locking block23is moved downward to the second position A82as shown inFIG. 7.

Referring toFIG. 4andFIG. 8, the resisting rod2further has an upper locating portion24and a lower locating portion25, both of which are disposed on the back edge of the back end22. A locating system E is disposed in the case A1and behind the back end22. The locating system E has an elastic element E1disposed on the back to provide a forward elastic force to the locating system E. Thereby, when the locking block23of the back end22is moved to the first position A81as shown inFIG. 6, the locating system E is elastically resisted against the lower locating portion25as shown inFIG. 4, and that when the locking block23of the back end22is moved to the second position A82as shown inFIG. 7, the locating system E is resisted against the upper locating portion24as shown inFIG. 8. As a result, the back end22of the resisting rod2will be located after moving back.

Referring toFIG. 5, the case A1further has a through hole A9disposed on the side and a turning system3disposed in the through hole A9. Referring toFIG. 8, the turning system3has a hole portion31with a marking portion311outside and a turning portion32with a cam portion321disposed under the resisting rod2, wherein the hole portion31is turning along with the turning portion32. When there is no bullet C in the bullet-out passage A2, the back end22of the resisting rod2is moved downward to resist against the resisting portion A61of the struck element A6. At this time, the hole portion31could be turned by tools to make the turning portion3turning along with the hole portion31, and then the cam portion321of the turning portion32will be turned upward to resist against the resisting rod2as shown inFIG. 9. That causes the back end22to move away from the resisting portion A61of the struck element A6, resulting that the air lock system A5could still be pushed when firing. Thereby, in case that there is no bullet C, the user could still choose to make a fire without bullet. As shown inFIG. 7andFIG. 10, the through hole A9has a first indicating portion A91and a second indicating portion A92on the outside edge, so that when it is marked by the marking portion311, both of which respectively indicate the situations before and after the cam portion321is resisted against the resisting rod2, comparing withFIG. 9. Thereby, the user could know exactly what the structure and the function are at that time for well operating.

Based on the structures mentioned above and referred toFIG. 4without the trigger and the bolt, when there are bullets C in the bullet-out passage A2and the trigger is pressed, the struck element A6is impacted by the firing pin A7to push the air lock system A5forward, resulting that the bolt of the gun moves forth and back, wherein at this time, the locking block23is on the first position A81as shown inFIG. 6.

Referring toFIG. 8, when there is no bullet C in the bullet-out passage A2, the lateral end A41of the stripping rod A4is resisted upward against the front end portion11of the pushing rod1to further make the back end22of the resisting rod2moving downward to resist against the resisting portion A61of the struck element A6. Thereby, the struck element A6cannot move forward and the air lock system A5cannot move, resulting that the bolt of the gun cannot moves forth and back, which is not shown inFIG. 8. At this time, the locking block23is moved to the second position A82as shown inFIG. 7. Hence, the forth and back movement of bolt of the gun could be stopped according to the requirement.

Besides, if the bolt of the gun is still needed to move forth and back to make a fire without bullet, the turning system3could be turned by tools to make the cam portion321of the turning portion32resisting upward against the resisting rod2as shown inFIG. 9, resulting that the back end22is moved away from the resisting portion A61of the struck element A6to validate the firing without bullet. At this time, the first indicating portion A91or the second indicating portion A92is marked by the marking portion311to indicate the situation. Hence, it is very convenient and utility. Furthermore, the turning system3could only be turned after the cartridge box A is removed from the pneumatic toy gun.

Based on the structures and embodiments mentioned above, the control system B is arranged to accomplish that, when there is no bullet C in the pneumatic toy gun, the air lock system A5cannot be pushed forward and the bolt of the gun cannot move. Thereby, the momentum of the gas will not be wasted and the elements will not run idle to cause damages. Hence, the defects of the prior art would be overcome and the effects of the simulate gun could be achieved. Furthermore, the turning system3is arranged to make the air lock system A5and the bolt of the gun workable to allow the gun be fired without bullets, if the user likes.
