Abstract
A magazine for an air gun of this invention can be freely attached to and detached from an air gun body using a magazine body, and has a plurality of pellet holders capable of being loaded with one pellet at a time. The plurality of pellet holders move orbitally about a pellet holder path and the pellets can be fed one at a time from the pellet holders towards a rotary sub chamber positioned below. With the air gun of this invention, the direction of the rotary sub chamber can be changed by shifting a rotary sub chamber positioned below the magazine, a trans link and a bolt forwards and backwards, so that the direction of single pellets dropping from the magazine can be changed by ninety degrees for feeding into the barrel. The magazine conveyor link is also interlocked so as to move to the front and rear in unison with movement to the front and rear of the trans link.
Description




BACKGROUND OF THE INVENTION




1. Field of Invention




The present invention relates to a magazine for an air gun capable of repeat firing pellets formed of lead, etc., and an air gun having this magazine. Specifically, the present invention relates to a magazine for an air gun capable of repeat firing of pellets formed of lead etc. using compressed air and an air gun having this magazine.




2. Description of the Background Art




Conventionally, cartridge chambers for air guns employing pellets made of lead etc. are as disclosed, for example, in U.S. Pat. No. 5,285,766 (related example 1). In a first related example 1, a rotatable loader


64


provided with a plurality of pellets


125


is disclosed. However, the loader


64


of related example 1 can be rotated taking an axis in a direction parallel to the direction of a gun barrel


50


(barrel) as center. The structure is then such that inserted pellets


125


are also inserted in the direction of the barrel and are discharged from the muzzle in the direction of insertion (refer to

FIG. 3

, FIG.


16


and

FIG. 17

of related example 1).




Further, with a gas-operated pellet gun with removable clip loader as disclosed in U.S. Pat. No. 3,741,189 (related example 2), a configuration is adopted whereby when respective pellet chambers


119


coincide with the opening


124


while rotating the six pellet chambers


119


centrally about a post


115


facing in a direction parallel with the direction of the gun barrel


30


, a pellet P is pushed out to the firing position. Pellet chambers


119


in related example 3 are also rotated centrally about a post


115


facing in a direction parallel to the direction of the gun barrel


30


and the respective pellets are loaded into the pellet chamber


119


in advance in the direction of the gun barrel


30


.




Further, a chamber (revolver barrel


36


) for an air gun having a central axis of rotation in a vertical direction (a direction at right angles to the direction of the gun barrel


26


) is disclosed in U.S. Pat. No. 3,547,095 (related example 3). However, pellets loaded into the pellet chambers


38


are loaded into the gun barrel


26


one at a time by rotating the six respective pellet chambers


38


of this revolver barrel


36


in a plane in the same direction as the direction of the gun barrel


26


and discharged to the gun barrel


26


. Namely, the revolver barrel (member)


36


is provided with six, equiangularly spaced radial pockets or pellet chambers


38


, each of which opens at its outer end on the periphery of barrel


36


, and at its inner end on a post


28


. (see column 1, line 66 to 69 in the related example 3).




However, with the air gun magazines disclosed in related example 1 to related example 3, the size of the respective rotating discs has to be large because the number of pellet chambers is large and this is detrimental to the balance of the air gun and makes handling difficult.




SUMMARY OF THE INVENTION




A magazine for an air gun of this invention can be freely attached to and detached from an air gun body using a magazine body, and has a plurality of pellet holders capable of being loaded with one pellet at a time. The plurality of pellet holders move orbitally about a pellet holder path and the pellets can be fed from the pellet holders towards a rotary sub chamber positioned below.




The pellets drop one at a time into the rotary pellet hole of the rotary sub chamber due to the shutter interlocked with the conveyor link opening and closing the pellet hole and the pellet holders are moved one at a time by the operation of the link latch of the conveyor link.




The air gun of this invention has a rotary sub chamber for changing the direction of single pellets falling from the magazine from a vertical direction through ninety degrees for feeding into the barrel. The rotary sub chamber is positioned at a lower part of the magazine body, is fitted to the air gun body so as to be freely rotatable about the sub chamber rotary axis, and has a sub chamber arm parallel with the sub chamber rotary axis and a rotary pellet hole constituted by a through-hole.




The rotary sub chamber is rotated through ninety degrees by a backwards and forwards shifting trans link fitted to the air gun body so that the direction of the angle of the rotary pellet hole can be changed through ninety degrees from a direction coinciding with the barrel to a direction coinciding with the pellet hole of the magazine




Further, the conveyor link of the magazine is interlocked with the forward and backward movement of the trans link and also shifts forwards and backwards.




The effect of this invention is that the discharge of a large number of pellets is possible with the loading of an extremely compact magazine. Further, the loading of pellets one at a time is also possible with the magazine remaining mounted on the air gun body so that limitless consecutive firing is possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




A description is given of an air gun magazine M constituting a preferred embodiment of this invention, and an air gun having this magazine M. In this specification, the discharging side of the air gun is referred to as the front direction and the gripping side of the air gun is referred to as the rear direction. Further, the horizontal direction, vertical direction and up and down direction are described with a barrel


19


of the air gun positioned in a horizontal direction. Further, in the description regarding rotation of the rotary sub chamber


10


, the expressions “clockwise rotation” and “anti-clockwise rotation” refer to when viewing from the left side of the air gun. In the description of the drawings, front view is a view of the air gun as viewed from the left side.




The air gun magazine M of the preferred embodiment of this invention is freely detachable from above a lever R of the air gun body and has a plurality of pellet holders


2


capable of being loaded with a plurality of pellets


200


. The plurality of pellet holders


2


are endlessly rotatable and pellets


200


from the magazine M pass through the rotary sub chamber


10


so as to be fed one at a time into the barrel


19


.




The magazine M of this invention comprises a magazine body


1


, a plurality of pellet holders


2


within the magazine body


1


(in this embodiment there are


22


pellet holders


2


), a pellet holder path


20


enabling orbital movement of the


22


pellet holders


2


in an endless manner, a magazine upper cover


3


, a magazine under cover


4


, a pellet hole


5


, and a pellet holder stop


6


.




The pellet holders


2


are cylindrical and open at both ends to enable lengthways loading of pellets


200


one at a time and are moved by pushing down by a link latch


72


within the path of the pellet holder path


20


.




The pellet holder path


20


is comprised of an oblong path having two parallel straight line portions, with the pellet holders


2


then being moved within this path by the front to rear shifting action of the conveyor link


7


.




In this embodiment, the pellet holders


2


move within the pellet holder path


20


in a clockwise direction as viewed from above, the pellet holders


2


advance at the straight line portion on the left side of the pellet holder path


20


and the right side straight line portion retracts.




The magazine upper cover


3


opens one single pellet loading port


30


above the pellet holder path


20


and is provided in a direction from front to rear at a link latch shifting groove


31


recessed at a lower surface opening.




The magazine under cover


4


has a link cover movement opening


40


formed at the middle of the pellet holder path


20


.




A hole is then formed at the magazine under cover


4


at the lower surface of the position of the foremost pellet holder


2


of the pellet holder path


20


and a pellet hole


5


is formed in the vertical direction.




The rear surface of the pellet holder stop


6


is formed with a recessed curved surface


60


corresponding to the outer surfaces of the pellet holders


2


and is urged from the front of the magazine body


1


towards the rear by a holder stop spring


61


. When there is then rotational movement of the recessed curved surface


60


of the pellet holder stop


6


, this rotational movement is halted at positions where the centers of the respective pellet holders


2


and the center of the pellet hole


5


coincide, the pellet holders


2


are prevented from going too far, and the center of the pellet hole


5


and the center of the pellet holders


2


are made to coincide.




The pellet holders


2


in the pellet holder path


20


are therefore rotated in an endless manner by the backward and forward action of the conveyor link


7


. In this embodiment, the pellet holders


2


in the pellet holder path


20


are rotated in a clockwise direction as viewed from above.




The conveyor link


7


comprises a link body


70


provided in a horizontal direction and a conveyor link bar


71


projecting downwards at right angles from the link body


70


in the shape of an upside down L, and the link body


70


and conveyor link bar


71


are formed in an integral manner. A lower end of the link bar


71


projects downwards by a few mm from the link bar movement opening


40


provided in a longitudinal manner at a central part of the magazine under cover


4


, and the lower end of the link bar


71


is positioned at the center of a shifting groove


121


of a bolt


12


(described later).




The conveyor link


7


has a conveyor link latch


72


at an upper part. The conveyor link latch


72


is provided within the oblong-shaped pellet holder path


20


, has a central axis


720


at a rear part, and has a pivoting abutment member


721


rotating centrally about this central axis


720


at a front part. An upper part of the central axis


720


of the conveyor link latch


72


engages with the link latch shifting groove


31


of the magazine upper cover


3


, and is capable of shifting to the front and rear along this groove.




The conveyor link latch


72


is urged towards one side by a conveyor link latch spring


73


. In this embodiment, the conveyor link latch


72


is normally urged towards the left by the conveyor link latch spring


73


. Therefore, when the conveyor link bar


71


of the conveyor link


7


advances, the conveyor link latch


72


is urged in a direction towards the left as viewed in a plane by the conveyor link latch spring


73


, and the end of the pivoting abutment member


721


of the conveyor link latch


72


comes into close contact with the rear surface of the circumferential surface of one of the pellet holders


2


. The end of the pivoting abutment member


721


of the conveyor link latch


72


then presses one pellet holder


2


towards the front due to the advancing of the conveyor link


7


. All of the pellet holders


2


then rotate in a clockwise direction within the pellet holder path


20


due to the shifting of the one pellet holder


2


.




Conversely, when the conveyor link bar


71


of the conveyor link


7


retracts, the end of the pivoting abutment member


721


of the link latch


72


comes into contact with the rear surface of the circumferential surface of the pellet holder


2


so as to cause retraction but the center of the pellet hole


5


and the center of the pellet holder


2


coincide and the pellet holder stop


6


therefore forms a wall, and the occurrence of all of the pellet holders


2


causing the pellet holder path


20


to rotate in an anti-clockwise direction (rotate in reverse) is avoided.




A shutter


8


constituted by a plate is provided at the upper surface of the magazine under cover


4


of the magazine body


1


. The shutter


8


can be made to advance and retract within a shutter path


80


in a horizontal direction constituted by a gap provided between the lower surface of the magazine body


1


and the magazine under cover


4


. The shutter


8


engages with the conveyor link


7


so as to shift in unison to the front and real of the conveyor link


7


. i.e. when the conveyor link


7


advances, the shutter


8


is also interlocked and therefore advances, and when the conveyor link


7


retracts, the shutter


8


is also interlocked and therefore also retracts.




The pellet hole


5


is provided in the vertical direction with the shutter path


80


opening at a side surface. The end of the shutter


8


is capable of entering into the pellet hole


5


from a side surface opening


50


of the pellet hole


5


.




Numeral


9


indicates a space cover. The space cover


9


is provided at the same level position as the shutter path


80


and comprises two (left and right) cover members


9


,


9


urged from the left and right sides of the shutter path


80


towards the center by cover springs


90


,


90


. The cover members


9


,


9


consist of plates of substantially the same thickness as the shutter


8


and form a quarter-circular recessed curved surface


91


when viewed in a plane from the front, with the two cover members


9


,


9


being urged towards the center so as to make contact and form a semi-circular curved surface when viewed in a plane. This curved surface that appears as a semi-circle when viewed in a plane formed in this manner is a curved surface of the same rate of curvature as the inner surface of the pellet hole


5


and covers the side surface opening


50


of the pellet hole


5


. The respective cover members


9


,


9


are provided with notches in straight lines in a direction towards the rear, so as to form a groove


92


that is V-shaped when viewed in a plane with the two cover members urged in a direction towards the center so as to make contact.




The rotary sub chamber


10


is provided at the lower part of the magazine body


1


, has a rotary pellet hole


100


constituted by a through-hole at its center, and is attached to the air gun body in a freely rotatable manner by a sub chamber rotary axis


101


provided in a horizontal direction from left to right. The rotary sub chamber


10


has a sub chamber arm


102


in parallel with the sub chamber rotary axis


101


, with the sub chamber arm


102


being shorter in a direction from left to right than the sub chamber rotary axis


101


. The chamber rotary axis


101


is provided with a plate or coil-shaped spring


103


, with one end making contact with part of the lower surface of the air gun body centered about the sub chamber rotary axis and the other end making contact with the upper surface of the sub chamber arm


102


.




Numeral


104


is a pellet stop slope formed with an upper surface that is a recessed curved surface with substantially the same rate of curvature as the arc of rotation of the lower surface of the rotary sub chamber


10


, so that when the rotary sub chamber


10


is rotated centrally about the sub chamber rotary axis


101


, the bottom surface of the rotating rotary pellet hole


100


is covered.




The trans link


11


is provided at the air gun body, and has a front part consisting of a long and slender plate, and a rear part divided between left and right portions, with the rotary sub chamber


10


being provided at the central part of the left and right portions. A trans link convex portion


110


is formed on both the left and right sides, or either one of the left or right side, of the rear part of the trans link


11


. The trans link


11


is provided at the lower part of the magazine body


1


so as to be freely shiftable to the front and rear and is fixed at the rear part using a bolt


12


. The bolt


12


is provided with a bolt nozzle


120


at a front end, and is provided with a link bar shifting groove


121


that opens at the upper surface and is long in a direction from front to rear. The bolt nozzle


120


is capable of passing through the rotary pellet hole


100


of the rotary sub chamber


10


. The link bar shifting groove


121


engages with the lower end of the magazine link bar


71


, provides a time difference for the shifting from front to rear of the trans link


11


by pressing the conveyor link bar


71


using both front and rear walls of the groove that is long in a direction from front to rear, and synchronizes the shifting to the front and the rear of the conveyor link


3


.




In FIG.


1


and

FIG. 2

, and FIG.


18


and

FIG. 19

, the trans link


11


is in a state of being manually moved to the foremost position and the rotary sub chamber


10


has mounted the horizontal plane-shaped trans link convex on the left and right or one side of the trans link


11


. At this time the rotary pellet hole


100


is in the horizontal direction, and the nozzle


120


of the bolt


12


passes through the rotary pellet hole


100


from the rear.




When the trans link


11


at the foremost position is shifted towards the rear through a manual operation, the bolt


12


that is fixed to the trans link


11


also moves in unison a towards the rear. The bolt nozzle


120


of the bolt


12


is also detached from the rotary pellet hole


100


as a result of this movement towards the rear of the bolt


12


.




The bolt nozzle


120


of the bolt


12


then detaches from the rotary pellet hole


100


and the sub chamber arm


102


of the rotary sub chamber


10


comes off the trans link convex


110


of the trans link


11


. In doing so, the rotary sub chamber


10


is rotated anti-clockwise through ninety degrees centered about the sub chamber rotary axis


101


due to the urging force of the rotary sub chamber spring


103


from the front. At this time, the lower surface of the rotary sub chamber


10


is rotated along the rotary sub chamber slope


104


so that when the trans link


11


shifts as far as the rearmost part, the rotary pellet hole


100


is halted in a state facing in a vertical direction.




When the trans link


11


is again shifted to the front, a front wall


110


a of the trans link convex


110


of the trans link


11


collides-with the sub chamber arm


102


and is pushed up as it is towards the front. This movement is resisted by the urging force of the rotary sub chamber spring


103


and the rotary sub chamber


10


is rotated in a clockwise direction centered about the sub chamber rotary axis


101


. The sub chamber arm


102


then moves towards the front so as to mount the trans link convex


110


of the trans link


11


, and the bolt nozzle


120


of the bolt


12


passes through the rotary pellet hole


100


that is in a horizontal state.




Next, the combined operation of the magazine M, rotary sub chamber


10


and pellets


200


of the air gun of the embodiment of the invention is described using

FIG. 1

to FIG.


14


.




The pellets


200


are loaded one at a time into the pellet holders


2


from the pellet loading port


30


as a result of rotation of the pellet holder path


20


.




In FIG.


1


and

FIG. 2

, a magazine body


1


with pellets


200


loaded into all of the pellet holders


2


is loaded from above the receiver R of the air gun body with the trans link


11


and bolt


12


in their foremost positions.




At this time, the lower part of the link bar


71


of the magazine engages with the link bar shifting groove


121


of the bolt


12


. The lower part of the link bar


71


then makes contact with a rear wall surface


121




b


of the link bar shifting groove


121


.




The pellet hole


5


of this magazine is closed over by the shutter


8


, with one pellet


200


mounting the upper surface of the plate of the shutter


8


and stopping.

are views showing when the trans link


11


and the bolt


12


are midway through shifting towards the rear. The retracted trans link


11


and the interlocked and retracted bolt nozzle


120


are withdrawn towards the rear from the rotary pellet hole


100


, the rotary sub chamber


10


comes off from the trans link convex from the front, the rotary sub chamber


10


is rotated anti-clockwise through ninety degrees centrally about the sub chamber rotary axis


101


due to the urging force of the sub chamber spring


103


, and the rotary pellet hole


100


faces in a vertical direction. At the same time, the lower part of the link bar


71


is pushed to the rear by the front wall surface

faces in the vertical direction and the pellet


200


that falls in enters from above. At this time the pellet


200


is loaded on the pellet stop slope


104


at the bottom surface of the rotary pellet hole


100


.




The lower part of the link bar


71


is then stopped while making contact with the front wall surface


121




a


of the link bar shifting groove


121


.




At this time the side surface opening


50


of the pellet hole


5


opened by the retraction of the shutter


8


is closed by the space cover

and

FIG. 9

, when the trans link


11


is shifted to the front, first, a front wall


110




a


of the trans link convex


110


of the trans link


11


collides with the sub chamber arm


102


and is pushed up as it is towards the front. This movement is resisted by the urging force of the rotary sub chamber spring


103


and the rotary sub chamber


10


is rotated in a clockwise direction centered about the sub chamber rotary axis


101


. At this time the pellet


200


slides onto the recessed curved surface of the pellet stop slope


104


at the bottom surface of the rotary pellet hole


100


.




Further, the lower part of the conveyor link bar


71

passes through the rotary pellet hole


100


and the pellet


200


within is pushed out into the chamber


131


.




The pellet


200


that enters into the chamber


131


is then discharged through the barrel


19


by compressed gas from a compressed gas jet hole


14


due to the operation of a trigger


17

of the link bar shifting groove


121


so as to be pushed forward. The shutter


8


interlocking with the conveyor link


7


also shifts forward due to the shifting of the conveyor link bar


71


and the pellet hole


5


is closed.




The conveyor link latch


72


also advances together with the conveyor link


7


. The conveyor link latch


72


is usually urged towards the left when viewed in a plane by the link latch spring


73


, with the front end coming into contact with the rear surface of one of the pellet holders


2


so as to push forward in accordance with the movement of the link latch


72


towards the front. This shifting is stopped at the shifting distance for one pellet holder


2


. At this time, at the upper surface opening


50


of the pellet hole


5


, the pellet holder


2


that is next pushed along engages with the recessed curved surface


60


of the pellet holder stop


6


, the center of the upper surface opening of the pellet hole


5


and the center of the pellet holder


2


are made to coincide, and the movement is stopped.




All of the pellet holders


2


can then be sequentially pushed along so as to shift within the pellet holder path


20


by pushing single pellet holders


2


with the end of the link latch


72


. All of the pellet holders


2


are thus made to rotate by sequentially repeating this operation.




Next, a description is given based on

FIG. 23

to

FIG. 27

of the operation of an air gun of this embodiment of the invention.

FIG. 23

to

FIG. 27

are front views of the operating portions of the air gun viewed from the left, with the trans link


11


fixed at a front end by the forearm (foregrip)


18


and by a screw.




From the state in

FIG. 23

, as a result of the marksman gripping the forearm (foregrip)


18


and manually pulling to the rear, the trans link


11


and the bolt


12


move in unison towards the rear.




The lower part of the retracted bolt


12


then collides with the brim of the hammer


15


and the hammer


15


retracts while compressing the hammer spring


150


that is urging in a forward direction. The brim of the hammer


15


then engages with a sear


16


interlocked with the trigger


17


, and the hammer


15


is held in this state (FIG.


24


).




The marksman then immediately pushes the forearm (foregrip)


18


back to the front, and the fixed trans link


11


and bolt


12


move towards the front in an interlocked manner. However, the hammer


15


which is engaged with the sear


16


remains held in a stationary state towards the rear, with the hammer


15


being urged towards the front by the hammer spring


150


(FIG.


25


).




When a marksman then manually pulls the trigger


17


to the rear using a manual discharging operation, the sear


16


interlocked with the trigger


17


rotates downwards, the brim of the hammer


15


engaging with the sear


16


comes out, and the hammer


15


is made to advance in a powerful manner towards the front due to the urging force of the hammer spring


150


(FIG.


26


).




The front end of the forcefully advancing hammer


15


then strikes a valve pin


130


projecting further to the rear than the valve body assembly


13


, compressed gas is discharged from the compressed gas jet hole


14


, and the pellet


200


within the chamber


131


of the valve body assembly


13


is discharged from the barrel (FIG.


27


).




The valve pin


130


is urged towards the rear by a valve spring built-into the valve body assembly


13


. When the valve body assembly


13


is pushed in by a blow from the hammer


15


, after a path is opened up for the compressed gas, when the pressure of the hammer


15


disappears, the hammer is again made to fly out due to the urging force of the valve spring.




It is then possible for a marksman to make the air gun discharge pellets


200


sequentially from the magazine M by repeating this operation.



Claims
  • 1. A magazine for an air gun comprising:a magazine body; a plurality of pellet holders capable of being inserted with pellets; a pellet holder path capable of rotating the plurality of pellet holders in an endless manner; a pellet hole open to a lower surface of the pellet holder path so as to be capable of coinciding with one pellet holder; a shutter capable of opening and closing the pellet hole; a space bar capable of closing an opening that opens up due to retraction of the shutter when the shutter opens up the pellet hole and capable of inserting the shutter into the pellet hole due to advancement of the shutter; a conveyor link interlocking with the shutter; and a link latch, interlocking with shifting of the conveyor link and shifting one pellet holder in one direction at the time of movement in one direction, and not shifting the pellet holders at the time of movement in the opposite direction so that the pellet holder path is caused to rotate in one direction.
