The present application is based on and claims the benefit of priority of Japanese Patent Application No. 2018-071047 filed on Apr. 2, 2018, the entire contents of which is incorporated herein by reference.
The present invention relates to a toy gun. The present invention relates in particular to an air gun and in more particular to a safety device (manual safety) used in an air gun.
A “safety device of a toy air gun” described in Japanese Unexamined Patent Application Publication No. Hei 10(1998)-220993 (hereinafter referred to as “JP '993”) is known as a safety device (manual safety) used in an air gun.
The “safety device of a toy pellet gun” described in JP '993 includes: a hammer supplied by a spring with biasing force for rotation frontward of the gun; a sear locking the hammer as is rotated rearward by a certain angle against the above biasing force; and an impact frame rotatably provided at the tip thereof with an impact hammer. The toy pellet gun is so constructed that by pulling a trigger provided on a gun body, when the hammer raised and locked in advance returns to a predetermined position, a discharge valve of a gas accumulator is opened via the impact hammer and gas is jetted out into a bullet firing passage, thereby a bullet loaded there is fired. In this toy pellet gun, the impact hammer is abutted against the discharge valve in a bullet firing enabled state but the abutment between the impact hammer and the discharge valve is released when bullet firing is aborted.
A manual safety is a manual safety device that may be provided in an automatic hand gun. When a lever (safety lever) provided in the manual safety is rotated to turn on the manual safety (actuate the safety device), the manual safety is engaged with a sear. As a result, a trigger bar directly coupled with a trigger is abutted against the sear and is immobilized and this prevents a hammer from being moved and a bullet from being fired. This mechanism prevents unforeseen accidental firing. This manual safety is adopted in real guns and toy guns imitating a real gun (hereafter, referred to as “toy guns”).
Unlike a manual safety of a real gun, a manual safety of a conventional toy guns is, when dropped, rotated by resulting impact and the manual safety is turned off (the safety device is released); therefore, the manual safety used to be inferior in safety.
When a toy gun is marketed in the United States, the toy gun must pass a “drop test” stipulated by a US's rule. One of the stipulations for the “drop test” requires that a manual safety shall not be shifted from on to off due to dropping impact.
In the drop test, a toy gun is dropped from a height of 36 inches in six different directions. The drops in the six different directions include: dropping with the upper part of a gun oriented upward; dropping with the upper part of a gun oriented downward; dropping with a muzzle positioned on the lower side; dropping with a muzzle positioned on the upper side; dropping with the right side of a gun positioned on the upper side; and dropping with the left side of a gun positioned on the upper side.
When a gun is dropped with the right side thereof positioned on the upper side or with the left side thereof positioned on the upper side, that is, when a gun is dropped with a safety lever thereof positioned on the lower side, almost all the weight of the toy gun and dropping impact is exerted on the safety lever. If the safety lever is not locked at this time, the safety lever can be shifted from on to off.
A more specific description will be given. When a conventional toy gun is dropped with a safety lever positioned on the lower side, the safety lever is brought first into contact with the ground because the safety lever is located in the lowest position.
If the spindle of a safety lever is completely vertical when the safety lever is brought first into contact with the ground, the safety will not be moved.
In actuality, however, a gun is rarely dropped with the spindle of a safety lever completely vertical. When a safety lever is brought into contact with the ground, the spindle of the safety lever is usually off vertical and slightly slanted.
At this time, a force vector may be produced in such a direction as to release a safety lever depending on a direction in which the spindle of the safety lever is slanted.
When the magnitude of this force becomes larger than the magnitude of the force holding the safety lever, the safety lever is released.
Consequently, to prevent a manual safety from being accidentally released when the safety lever is on, a conventional toy gun is provided with a component designated as safety unlock button 104, shown in
Reference numeral 101 denotes a conventional toy gun and 102 denotes a grip portion of the toy gun. Reference numeral 103 denotes a safety lever of the toy gun.
A more specific description will be given. In the conventional toy gun, the safety is unlocked only while the safety unlock button 104 is pressed. For this reason, to switch the safety from on to off, the safety unlock button 104 is pressed to unlock the safety lever 103.
Subsequently, as shown in
That is, to turn off the safety, it is required to rotate the safety lever while pressing down the safety lock.
The safety lever 103 is provided on one side of a frame 1011 located in the center of the conventional toy gun 101. Reference numeral 1031 shown in
Reference numeral 1033 denotes a space, provided in the safety lever 103. The safety lock enters the space when the safety unlock button 104 and the safety are on. Reference numeral 1044 denotes a recess. A safety click for attaching the safety lever 103 to the frame 1011 enters the recess when the safety is off.
In
A more specific description will be given. Reference numeral 111 denotes the trigger of the conventional toy gun. Reference numeral 112 denotes the trigger spring; 113 denotes the trigger bar; 114 denotes the trigger bar spring (not shown); 115 denotes a trigger bar coupling pin; and 116 denotes a sear pressing portion of the trigger bar.
Reference numeral 121 denotes the sear of the conventional toy gun. Reference numeral 122 denotes the sear spindle; 123 denotes a hammer locking portion of the sear 121; 124 denotes a trigger bar engaging portion of the sear 121; and 125 denotes a safety engaging portion of the sear 121.
Reference numeral 131 denotes the hammer of the conventional toy gun. Reference numeral 132 denotes a hammer spindle; 133 denotes a hammer spring; and 134 denotes a sear engaging portion of the hammer 131.
In the conventional toy gun 101, as shown in
The sear 121 is rotatable around the sear spindle 122. In
The hammer 131 is rotatable around the hammer spindle 132. In
As shown in
Since the sear 121 cannot be thus rotated, the hammer 131 is not rotated, either. As a result, a bullet cannot be fired.
As shown in
For this reason, in the same drawing, the safety lock 105 is pressing the safety unlock button 104 leftward. The safety unlock button 104 is hooked on the safety lever 103 and is at rest. Since a part of the safety lock 105 is positioned in the safety lever 103, the safety lever 103 does not move in this state.
As shown in
When the manual safety shown in
When the manual safety is off and the trigger 111 is not pulled, the hammer locking portion 123 of the sear 121 is in engagement and thus the hammer 131 is at rest.
When the trigger 111 is thereafter pulled, the trigger 111 and the trigger bar 113 are linearly moved rearward of the toy gun 101. The sear pressing portion 116 of the trigger bar 113 presses the trigger bar engaging portion 124 of the sear 121.
Since the manual safety is off at this time, the sear locking portion 1032 of the safety lever 103 and the safety engaging portion 125 of the sear 121 are not engaged with each other. Thus, the sear 121 is rotated counterclockwise around the sear spindle 122. As a result, the hammer locking portion 123 of the sear 121 and the sear engaging portion 134 of the hammer 131 are brought out of engagement and the hammer 131 is now rotatable counterclockwise around the hammer spindle 132.
When the hammer 131 is rotated, a hit pin pressing portion 135 of the hammer 131 moves a hit pin 141 frontward of the toy gun 101. The hit pin 141 moves a valve 142 frontward of the toy gun 101.
When the valve 142 is moved frontward of the toy gun 101 and a packing contact portion 143 of the valve 142 and a packing 144 are brought out of contact, gas in a cylinder 151 flows into a gas passage 145 of the valve 142.
When the gas flows into the gas passage 145 of the valve 142, the gas moves a nozzle 161 frontward of the toy gun 101. The nozzle 161 moves a first bullet W into an inner barrel 162. The gas further moves the first bullet W moved into the inner barrel 162 frontward of the toy gun 101.
Thereafter, the action sequentially progresses until a second bullet W is loaded into a firing position.
A toy gun is implemented such that if the gun is dropped, a manual safety is moved and interferes with a frame within the gun and the manual safety is prevented from being rotated and will not be released.
A toy gun of this invention includes:
a frame provided in the toy gun; a trigger attached to the toy gun; a sear interlocked with the action of the trigger; a hammer jetting gas out of a cylinder to fire a bullet by interlock with the action of the sear; a safety lever installed outside the frame with a gap between the safety lever and the frame and can be selectively in contact with or out of contact with any member of the trigger to the hammer interlocked with one another, that is, at least one member selected from members composing the configuration of the trigger to the hammer interlocked with one another; and a biasing means providing bias in such a direction as to maintain a gap between the frame and the safety lever. Any member of the trigger to the hammer interlocked with one another may be a sear. The safety lever may be provided on both sides of the frame.
Since a safety lock is a component that is not provided in a real gun, a toy gun provided with a safety lock may impair similarity to a real gun in appearance. Since the commercial value of a toy gun depends on similarity to a real gun in appearance, it is undesirable to provide such a component as a safety lock. Further, an operating method for a toy gun may be different from that for a real gun and this can impair its commercial value. The present invention has been made to make the appearance and shape of and an operating method for a toy gun similar to those of a real gun.
It is an object of the present invention to provide a manual safety device provided in a toy gun which device ensures safety without providing such a component as a safety lock and in which, with a manual safety on, the manual safety will not be turned off due to impact even if the toy gun is dropped.
To do this, a toy gun is implemented such that if the gun is dropped, a manual safety is moved and interferes with a frame within the gun and the manual safety is prevented from being rotated and will not be released.
According to the present invention, a toy gun in which similarity to a real gun in appearance, operating method, and the like will not be impaired and a safety device will not be released even when dropped during a test or the like can be implemented. As a result, the commercial value of the toy gun can be enhanced.
A description will be given to an implementation of an embodiment of the present invention with reference to drawings illustrating implementations of the present invention.
Reference numeral 21 denotes a safety lever. The safety lever 21 is comprised of a safety lever right 211 and a safety lever left 212. The safety lever 21 is a body of a manual safety and the safety lever right 211 and the safety lever left 212 are attached to the upper part of the grip portion 12 with the frame 13 in between.
In the implementation of the present invention, an actuation system in connection with the action of a trigger 31 to that of a hammer 51 has an internal structure shown in
The trigger 31 is rotatable around the trigger spindle 32 and is biased counterclockwise by the trigger spring 33 in
Reference numeral 34 denotes a trigger bar. As shown in
When the trigger 31 is pulled, the trigger bar 34 is moved frontward of the toy gun 11 (muzzle side, left side in
In
The sear spindle 42 is attached to the sear 41 at a right angle to the direction of a barrel, that is, to a body of the toy gun 11 in the width direction of the toy gun 11. Above the sear 41, the hammer locking portion 45 is provided in the center and the safety lever left engaging portion 44 and the trigger bar engaging portion-safety lever right engaging portion 43 are provided on the both sides thereof.
The sear 41 is attached to the body of the toy gun 11 so as to be rotatable around the sear spindle 42 and is biased counterclockwise by a sear spring (not shown) in
When the trigger 31 is pulled, the trigger bar engaging portion-safety lever right engaging portion 43 is engaged with the sear pressing portion 37 of the trigger bar 34. When the safety is on, as shown in
Reference numeral 51 denotes a hammer. The hammer 51 is rotatably attached to the trigger bar 34 via the hammer spindle 52. The hammer 51 is rotatable around the hammer spindle 52 and is biased counterclockwise by a hammer spring (not shown) in
In
As shown in
As shown in
A description will be given to a structure of the manual safety.
A safety lever of a real gun on which the toy gun 11 in an implementation of the present invention is based is located on both the left and right sides of the gun. For this reason, as shown in
In the implementation shown in
To release the manual safety to establish a state in which a bullet can be fired (to turn off the safety), as shown in
This operating method is identical with that for a real gun and similarity to a real gun is enhanced as compared with conventional toy guns.
As shown in
Reference numeral 22 shown in
As shown in
In
In
Reference sign C denotes a contact portion. The contact portion C is provided inside the lower end of the safety lever 21.
In this implementation of the present invention, a safety lever spindle projection 231 and a safety guide projection 241 of the safety lever left 212 are inserted into a safety lever spindle recess 232 and a safety guide recess 242 of the safety lever right 211 to assemble them together. As the result of this assembly, the safety lever right 211 and the safety lever left 212 are paired and assembled together and the safety lever spindle 23 and the safety guide 24 are respectively integrally assembled.
In the shape of this implementation, the safety lever spindle 23 and the safety guide 24 are integrally assembled. Therefore, when the safety lever 21 is operated by either the safety lever right 211 or the safety lever left 212, the safety lever on the opposite side is also moved in conjunction therewith.
For example, when the safety lever left 212 located on the left side is pressed down, the safety lever right 211 located on the right side is similarly rotated downward.
Reference numeral 26 shown in
The safety hook 26 is provided on the frame 13 of the body of the toy gun 11.
Each of the left and right safety lever spindles 23 is provided with an locking portion comprised of a safety hook engaging portion 233 and can be engaged with the safety hook 26.
A more specific description will be given. In
This is also the case with the safety lever right 211. Since the safety lever right locking portion 261 of the safety hook 26 and the safety hook engaging portion 233 of the safety lever right 211 are engaged with each other, the safety lever right 211 is prevented from further moving outward of the toy gun 11.
As shown in
Reference numeral 243 denotes a safety guide spring as a biasing means. The safety guide spring 243 is put into the safety guide 24 of the safety lever right 211. The safety guide spring 243 biases the safety lever left 212 and the safety lever right 211 outward of the gun respectively in opposite directions.
A more specific description will be given. The safety lever spindle spring 234 as a biasing means and the safety guide spring 243 as a biasing means bias the safety lever left 212 and the safety lever right 211 outward of the gun respectively in opposite directions.
For this purpose, a space A is provided between the frame 13 and the safety lever right 211; and a space B is provided between the frame 13 and the safety lever left 212.
As shown in
When force greater than those of the safety lever spindle spring 234 and the safety guide spring 243 is applied to the safety lever left 212 or the safety lever right 211 from outside to inside the toy gun 11 with the safety on, as shown in
Owing to this mechanism, when the toy gun 11 is dropped and the safety lever 21 collides with the ground, the safety lever 21 is moved inward of the toy gun 11. That is, the safety lever 21 is retracted.
For example, as shown in
The space A between the frame 13 and the safety lever right 211 remains but the space B between the frame 13 and the safety lever left 212 is eliminated.
For example, as shown in
Even if the gun is dropped and the safety lever right 211 collides with the ground with the safety working, that is, the safety lever 21 on, as shown in
As a result, the space A between the frame 13 and the safety lever right 211 is eliminated but the space B between the frame 13 and the safety lever left 212 remains.
Owing to the movement of the safety lever right 211 and the safety lever left 212, even when great impact is applied to the safety lever 21 due to dropping of the toy gun 11, force applied to the safety lever 21 is attenuated by the safety lever spindle spring 234 and the safety guide spring 243.
This implementation of the present invention adopts the safety lever spindle spring 234 and the safety guide spring 243 having great repulsive force to some extent. This prevents the safety lever 21 from being moved inward of the gun while a user is manually operating the safety lever 21.
As shown in
Switching of the manual safety between on and off is accomplished by rotating the safety lever 21 around the safety lever spindle 23.
When the manual safety is on, the free end of the safety lever 21 located at the front side of the toy gun 11 is moved to the upper side by rotating it. The contact portion C located at the inner lower end of the safety lever 21 is brought out of contact with the projection D, which is projected from the faces the frame 13 facing the space A and the space B.
Since the recess in the frame 13 and the safety lever 21 are fitted with each other when the safety is on, as shown in
Even if an attempt is made to turn off the safety lever 21 with the safety lever 21 moved inward of the toy gun 11, as shown in
To turn off the manual safety, the safety lever 21 is rotated to move the free end thereof located at the front side of the toy gun 11 to the lower side. The contact portion C located inside the safety lever 21 is brought into contact with the projection D projected from the faces of the frame 13 facing the space A and the space B.
When the manual safety is off, as shown in
A description will be given to operations in which a bullet is fired in this embodiment of the present embodiment.
(1) A description will be given to a safety on state, shown in
An attempt is made to pull the trigger 31. Then, the trigger bar 34 becomes about to move frontward in
Then, the sear pressing portion 37 of the trigger bar 34 is abutted against the sear 41 and becomes about to press and rotate the sear 41.
However, as shown in
That is, even by pulling the trigger 31, the sear pressing portion 37 of the trigger bar 34 cannot press the trigger bar engaging portion-safety lever right engaging portion 43 of the sear 41 and this prevents the trigger 31 from being fully pulled.
The hammer 51 immobilized by the sear 41 remains stopped and cannot be rotated. For this reason, a bullet is not fired.
In this embodiment, the sear locking portion 25 locks the sear 41 and stops the movement of the hammer 51. The safety lever 21 only has to be capable of being selectively in contact with or out of contact with any member of the trigger 31 to the hammer 51 by way of the sear 41 interlocked with one another.
(2) A description will be given to a safety off state, shown in
In
The trigger 31 in the state shown in
The sear pressing portion 37 of the trigger bar 34 is abutted against the sear 41 and presses and rotates the sear 41.
In
For this reason, when the trigger 31 is pulled as shown in
When the sear 41 is rotated counterclockwise around the sear spindle 42 in
Then, the hammer 51 can be rotated around the hammer spindle 52.
The hammer 51 is rotated and the hit pin pressing portion 54 of the hammer 51 hits on the hit pin 61 and this moves the hit pin 61 frontward of the toy gun 11.
The hit pin 61 moves the valve 62 frontward of the gun. Then, the valve 62 is moved frontward of the toy gun 11.
The packing contact portion 69 of the valve 62 and the packing 68 are brought out of contact with each other, thereby unsealing the air tight in the valve 62. At this time, gas in the gas cylinder 71 has already flowed into a valve body 63.
Subsequently, gas in the valve body 63 flows into the gas passage 64 in the valve 62. Then, the gas flows out of the gas passage 64 in the valve 62 toward the inner barrel 65.
A bullet located at the rear end of the inner barrel 65 is moved frontward by gas pressure and the bullet is fired. At the same time as the firing of the bullet, the gas flows also into the cylinder block 66.
The slide 67 with the cylinder block 66 incorporated therein is moved rearward of the gun by gas pressure in the cylinder block 66 and a blowback is caused.
The cylinder block 66 is abutted against the trigger bar 34 and rotates the trigger bar 34.
The trigger bar 34 and the sear 41 are disengaged from each other and the sear 41 is returned to its original position. The trigger 31 and the hammer 51 are respectively returned to their original positions.
Then, the sear 41 is engaged with the hammer 51 again.
Conventional toy guns require operations different from those for real guns. That is, it is required to press a safety unlock button and then rotate a safety lever.
In this implementation of the present invention, the safety lever 21 is not locked when the manual safety is turned on. Therefore, a safety unlock button is unnecessary and thus neither a safety lock nor a safety unlock button is provided.
In an operating method for the safety lever 21 to switch the manual safety from on to off, the safety lever 21 only has to be pressed down as shown by the arrows in
Hereinbefore, the present invention has been described with reference to the embodiments, but the present invention is not limited thereto. It is obvious to those skilled in the art that various modifications, replacements, combinations and the like may be made, for example. It should be understood that the invention is not limited to the above-described embodiment, but may be modified into various forms on the basis of the spirit of the invention. Additionally, the modifications are included in the scope of the invention.
