- the state of being cocked is clearly grasped in visual and tactual manners.
- the piston spring 18 When the trigger 22 is operated in a state where cocking is completed, the piston spring 18 operates, compressed air is generated due to the advance of the piston 14, and the bullet B is shot due to the generated compressed air ( Fig. 7B ).
- the shooting mechanism 25 the rear end portion of the first shear 24 is lowered in association with an operation of the trigger 22. Therefore, the engagement portion 33 provided in the rear end portion is lowered and engages with the counterpart portion 34 of the indicator lock 32. Then, the indicator lock 32 is pushed down. As a result, the indicator 30 advances by the indicator spring 31 and returns to a state of being withdrawn inside the hollow part 21a of the bolt member 21.
- Fig. 8 illustrates a non-operation state after the bullet B is shot.
- the indicator 30 is withdrawn and no cocking operation is performed.
- the state is the same as that in Fig. 6A , and the lever 17c moves to the lower position and returns to the initial state due to the movement.
- a third state which is not any of protrusion and immersion is taken. Therefore, a user can clearly grasp each of the states before operating cocking, in the middle of operation, and completion of cocking.
- the indicator apparatus according to the present invention is configured as described above and can be compactly embedded in a simulation gun as an extremely small-type indicator. Accordingly, even in a case of a long simulation gun such as a bolt action rifle, the present invention can be executed without requiring a significant change of the internal structure of the simulation gun. Therefore, the present invention is not limited to a rifle-type simulation gun and is easily diverted as a hand gun-type simulation gun, for example.

Abstract
Description
- The present invention relates to a cocking indicator apparatus in a simulation gun in which an operation member provided in a gun main body is operated and cocking is performed.
- A simulation gun shooting a so-called airsoft pellet is also referred to as an airsoft gun or the like. There are various types of guns such as guns for juveniles to the extent of having 18 years or older as targets, and the guns are widely used. Particularly, in some aspects, guns provided for adults have been developed as an item having high tasty elements. Accordingly, it is desired to be provided with the shape, the structure, and the operability as a real gun true to life. For the simulation gun which has been recently used for the purpose of the practice of police and the like, it is desirable to have the same operability and the like as the real gun.
- For example, in a bolt action rifle, a bolt handle provided in a gun main body is operated and cocking is performed. A gun or the like of the type described above includes a cocking indicator such that it is possible to grasp the state of a gun, that is, whether or not cocking is performed. Accordingly, the state of a gun can be grasped through sight or feeling by using the cocking indicator. In the related art, it seems to be not unprecedented to mount the cocking indicator in a simulation gun. However, there are few precedents. In simulation guns as well, since the cocking indicator is useful, the applicant of this case has carried forward the development and created the present invention.
- As a result of researching the related art,
JP-A-2004-347221 - A long rod-shaped member is required as the indicator bar, and embedding the indicator bar in the gun main body results in a complicated structure. Besides, due to the mechanism of moving the indicator bar back and forth, there is a disadvantage of frictional resistance with respect to a penetration hole occurring in a sliding part, and there is a possibility that the above-described circumstances lead to a problem regarding the strength. In addition, during cocking, the rod-shaped indicator bar pressurizes the piston forward by using a spring, thereby acting in a direction of increasing thrust of the piston. As a result, it is estimated that a problem of extra energy acted on a bullet or a problem of unstable operation of the piston is caused.
- [PTL 1]
JP-A-2004-347221 - The present invention has been made in consideration of the foregoing points, and an object thereof is to be able to clearly grasp a state of cocking by only an operation member independent from a piston cylinder mechanism and the like. In addition, another object of the present invention is to provide a cocking indicator apparatus in a simulation gun suitable for miniaturization. Solution to Problem
- In order to attain the above-described objects, according to the present invention, there is provided means for a simulation gun in which an operation member provided in a gun main body is operated and cocking is performed, and which includes an indicator which is disposed in the rear portion of the operation member and of which a part is provided so as to be able to protrude and be immersed with respect to the operation member in response to a cocking operation of the operation member, a lock member which is interlocked with the indicator in order to retain a protrusion state when a part of the indicator protrudes from the operation member, and a release mechanism which causes the protrusion state of the indicator to be a non-protrusion state.
- The cocking indicator apparatus in a simulation gun according to the present invention includes configuration elements such as the operation member, the indicator, the lock member, and the release mechanism. Here, as important points, the indicator is to be disposed in the rear portion of the operation member, and the indicator of which a part is provided so as to be able to protrude and be immersed with respect to the operation member in response to a cocking operation of the operation member.
- In the cocking indicator apparatus according to the present invention, an indicator having an arbitrary form can be employed. That is, the indicator is not required to be a long rod-shaped member as disclosed in the patent literature. Furthermore, it is possible to design an indicator having a form suitable for the shape and the structure of a simulation gun.
- According to the present invention, the indicator may take three different states such as a state before cocking, in which a part thereof is withdrawn beyond the rear portion of the operation member; a state in the middle of cocking, in which a part of the indicator is substantially the same as the rear portion of the operation member; and a state after cocking, in which a part of the indicator protrudes from the rear portion of the operation member.
- From the viewpoint of grasping the state of cocking, since it is acceptable as long as it can be determined whether or not cocking is performed, it is sufficient to take two arbitrary states such as protrusion and immersion, for example. Therefore, claim 1 clearly includes the indicator apparatus having this configuration. However, there are cases of requiring to grasp the state in the middle of a cocking operation. In order to grasp the state, it is required to indicate an intermediate state which is not any of protrusion and immersion.
- According to the present invention, it is desirable that the release mechanism includes a shear acting on the lock member in association with a trigger for a shooting operation and releasing an interlocked state of the indicator so as to realize the non-protrusion state, and a locked state of the lock member is configured to be released in accordance with engagement of engagement means by the shear.
- The indicator indicates a change of the state of cocking, and cocking ends in accordance with completion of shooting a bullet or completion of the shooting operation (in a case of so-called blank firing). Generally, the shooting operation takes a configuration of passing through a process in which the shooting operation is transferred from the trigger via the shear. Therefore, it is meaningful to take a configuration in which interlocking of the indicator is correlated to the shear.
- As the apparatus of the present invention, it is preferable that a simulation gun in which an operation member provided in a gun main body is operated and cocking is performed has a configuration in which the operation member has a piston cylinder mechanism which is provided so as to be movable with respect to the gun main body in a forward/rearward direction, a bolt member which is integrally attached to a rear portion thereof, and an operation handle portion which is provided between the piston cylinder mechanism and the bolt member; in which the bolt member has a hollow part which is open rearward, and has an indicator which is disposed in the hollow part and protrudes from the operation member in response to a cocking operation of the operation member; the indicator is movable back and forth in the hollow part and has an elastic member of which a part is biased in a direction of moving forward beyond the bolt member; and the cocking indicator apparatus includes a lock member which is interlocked with the indicator provided in the gun main body in order to retain the indicator in a state of protruding from the hollow part of the bolt member, and a release mechanism which includes a shear acting on the lock member in association with a trigger and releasing an interlocked state of the indicator so as to realize a non-protrusion state in order to act on the lock member in a protrusion state so as to realize the non-protrusion state. Advantageous Effects of Invention
- The present invention has a configuration and acts as described above, thereby exhibiting an effect of being embedded in the operation member independent from the piston cylinder mechanism and the like, and being able to clearly grasp the state of cocking. In addition, according to the present invention, for being embedded in a part of the operation member, it is possible to provide a cocking indicator apparatus in a simulation gun suitable for miniaturization.

Fig. 8 is a view describing a cross section also illustrating that a series of the operation is completed and the apparatus has returned to the state when not in operation. - Hereinafter, with reference to an illustrated embodiment, the present invention will be described in more detail. A
simulation gun 10 according to the present invention illustrated in the embodiment is modelled on a bolt action rifle and is broadly divided into sections such as ashooting device section 11 embedded in a gun main body, abarrel section 12 positioned in the front portion thereof, and astock section 13 positioned in the rear portion of theshooting device section 11. - The
shooting device section 11 includes apiston 14 and acylinder 16 and is provided with anoperation member 20 having apiston cylinder mechanism 15 generating compressed air for shooting a bullet, ashooting mechanism 25 for controlling a shooting operation performed by a trigger 22 (will be described later), and abullet loading mechanism 35. Thepiston cylinder mechanism 15 has thepiston 14 and thecylinder 16, is attached so as to be movable in a forward/rearward direction of the gun main body, and configures the front portion of theoperation member 20 performing cocking. A bolt member 21 (will be described later) is provided on the rear side of thepiston cylinder mechanism 15. In addition, thebolt member 21 configures the rear portion of theoperation member 20. - The
operation member 20 including thepiston cylinder mechanism 15 and thebolt member 21 is movable in the forward/rearward direction of the gun main body. In order to operate theoperation member 20, anoperation handle portion 17 is provided on the bolt member side. Theoperation handle portion 17 includes alever 17c which is mounted on the bolt action rifle and has a shape and a structure copying a member so as to serve as a bolt handle. InFigs. 1 ,2 , and the like, thelever 17c of theoperation handle portion 17 is indicated by the two-dot chain line because the shooting device section cannot be seen in the illustrated state, thereby illustrating only the installation position. - The configuration for movably attaching the
piston cylinder mechanism 15 to the gun main body is well known, and the case of the embodiment may also adopt a configuration similar to a general configuration. Accordingly, detailed description will be omitted. However, the basic configuration of the embodiment is as follows. That is, thepiston cylinder mechanism 15 stores pressure due to retraction of thepiston 14 inserted into thecylinder 16 and has apiston spring 18 which causes thepiston 14 to advance due to a release thereof. In addition, thecylinder 16 is embedded on the gun main body side so as to be able to advance and be retracted and is configured to ensure a space for raising a bullet B in the front portion of anozzle 19 at the tip when being retracted and to load the bullet B in a cartridge part at the rear end of a barrel in the tip portion of thenozzle 19 when advancing. - The
shooting mechanism 25 controlling the shooting operation described above is rotatably and pivotally supported by asupport pivot 22a on the gun main body side and has thetrigger 22 biased by atrigger spring 22b. Thetrigger 22 has aninput portion 22c protruding so as to abut anintermediate member 23, on the front side. In addition, thetrigger 22 has atrigger screw 22d adjusting the protruding amount with respect to theintermediate member 23, on the rear side. Theintermediate member 23 is pivotally supported by asupport pivot 23a on the gun main body side and transmits an operation of thetrigger 22 to afirst shear 24 in shears made of two members (refer toFig. 3 ). Thefirst shear 24 is rotatably and pivotally supported by asupport pivot 24a on the front portion, on the gun main body side.Springs intermediate member 23 and thefirst shear 24. In addition, thefirst shear 24 has anengagement portion 33 in the rear portion and is configured to be interlocked with anengagement counterpart portion 34 of anindicator lock 32 acting on an indicator 30 (will be described later) so as to be able to be locked in the state thereof. - A
second shear 27 is rotatably and pivotally supported by asupport pivot 27a in thefirst shear 24. Thesecond shear 27 is biased so as to protrude in a direction of thepiston 14 by ashear spring 27b. Meanwhile, anengagement portion 28 is provided in the rear portion of thepiston 14 and is configured to engage with a protrudingtip 29 of thesecond shear 27 at a piston retraction position (refer toFig. 6B ). In addition, for engagement with thepiston 14, aslit 16a through which thetip 29 passes is formed in the longitudinal direction of the lower surface of thecylinder 16. - As described above, the
intermediate member 23 is pivotally supported at the lower portion on the gun main body side and is interlocked with aninterlock counterpart portion 26 formed in the rear portion of thefirst shear 24, in aninterlock portion 23c formed in the upper portion (refer toFig. 3 ). In addition, theintermediate member 23 has the length of an arm arbitrarily set between thesupport pivot 23a and theinterlock portion 23c. In the embodiment, theinput portion 22c of thetrigger 22 abuts the position approximately half thereof. - The
operation handle portion 17 described above is positioned between thebolt member 21 and thepiston cylinder mechanism 15, as a part of theoperation member 20. Theoperation handle portion 17 is provided so as to be rotatable around the axis in the longitudinal direction with respect to the piston cylinder mechanism 15 (refer toFig. 4 and the like). Theoperation handle portion 17 is configured to be able to rotatably operate thelever 17c from a lower position illustrated inFigs. 4A to 4C to an upper position illustrated inFigs. 5A to 5C for a cocking operation. - At the lower position of the
lever 17c of theoperation handle portion 17, apart 30a of the indicator 30 (will be described later) engages with arecess portion 17a on the operation handle portion side. In addition, at the upper position of thelever 17c, aprojection portion 17b provided on the front side of theoperation handle portion 17 so as to be able to protrude and be immersed engages with arecess portion 15b provided in the rear portion of thepiston cylinder mechanism 15. Due to such engagement means, thelever 17c of theoperation handle portion 17 is positioned at each of the lower position and the upper position. - The
indicator 30 described above is embedded so as to be movable back and forth in ahollow part 21a of thebolt member 21 and is biased forward due to anindicator spring 31 disposed between a bolt memberside receiving portion 21b and an indicatorside receiving portion 30b, that is, in a direction of being withdrawn from thehollow part 21a. As clear fromFigs. 4A and 4C , therecess portion 17a on the operation handle portion side is in a state of being able to engage with thepart 30a of theindicator 30 only when thelever 17c of theoperation handle portion 17 is at the lower position. Thepart 30a of theindicator 30 protrudes slightly lower than a portion in the front thereof and plays roles to stop theindicator lock 32 from rising when not in operation and to stop theindicator 30 from advancing during cocking. - The
recess portion 17a on the operation handle portion side also serves as a part for housing theindicator lock 32 in order to retain theindicator 30 in the protrusion state. Theindicator lock 32 configures a lock member retaining theindicator 30 in the protrusion state, is embedded on the gun main body side of the rear end portion of thefirst shear 24 described above (refer toFig. 3 ), and is biased upward by alock spring 32b such that atip portion 32a is housed in therecess portion 17a. Thetip portion 32a of theindicator lock 32 protrudes upward from a throughport 32c on the gun main body side. - In addition, as the engagement means with respect to the
first shear 24, acounterpart portion 34 for engagement with respect to theengagement portion 33 on thefirst shear 24 side is provided in theindicator lock 32. Theengagement portion 33 on thefirst shear 24 side engages with theengagement counterpart portion 34 of theindicator lock 32 so as to regulate upward movement limit. In addition, theengagement portion 33 is lowered due to rotation of thefirst shear 24 and acts such that theindicator lock 32 escapes from theindicator 30 side and the locked state is released. Theengagement portion 33 on thefirst shear 24 side and theengagement counterpart portion 34 of theindicator lock 32 configure a release mechanism causing the protrusion state of the indicator to be in a non-protrusion state. - The
bullet loading mechanism 35 described above is a part of thesimulation gun 10 and is illustrated as a type of mounting amagazine 37 which is attachable/detachable with respect to amagazine insertion port 36 provided on the gun main body side. The bullet B is biased forward by amagazine spring 38 from a state of being loaded into themagazine 37, passes through abullet feeding section 39, and is fed to a position at the rear of the barrel. - An operation of the cocking indicator apparatus in a simulation gun according to the present invention having such a configuration will be described with reference to
Fig. 6 and thereafter.Fig. 6A illustrates a state where a cocking operation is not performed. Thelever 17c is at the lower position, and thepart 30a of theindicator 30 is in a state of engaging with therecess portion 17a (Fig. 4 ). In this case, theindicator 30 is biased by theindicator spring 31 and is at the front position, and the rear end is in an immersed state of being housed inside thehollow part 21a of thebolt member 21. - The
indicator 30 in the immersed state cannot be seen from the side surface. However, when a user touches theindicator 30 with a fingertip, it is possible to know that theindicator 30 is withdrawn inside thehollow part 21a of thebolt member 21. Therefore, the simulation gun is not cocked, and there is no change even if thetrigger 22 is operated, thereby being checked to be in a safe state. Determination which can be performed through feeling is also effective when theindicator 30 cannot be sighted such as at night, or when there is no time to spare for visually checking. - Subsequently, when the
handle lever 17c is operated and rotated to the upper position for cocking, therecess portion 17a thereof leaves from thepart 30a of theindicator 30, and theprojection portion 17b and therecess portion 15b of thepiston cylinder mechanism 15 are in an engaged state (Fig. 5 ). As a result, since thelever 17c is held at the upper position, theoperation member 20 can be stably and fully pulled rearward. - In the
piston cylinder mechanism 15, theengagement portion 28 of the retractedpiston 14 and thetip 29 of thesecond shear 27 are in an engaged state (Fig. 6B ). Therefore, thepart 30a of theindicator 30 leaves from therecess portion 17a, abuts the rear surface of theoperation handle portion 17, and moves rearward. In this case, theindicator 30 is in a state of being flush with the surface of thebolt member 21, and the flush surface state can also be easily checked through sight or feeling. In addition, in accordance with retraction of thecylinder 16, theindicator lock 32 rises to a position of being in contact with thecylinder 16 by thelock spring 32b. In addition, in a case where the bullet B is in thebullet feeding section 39, the bullet B moves to a position at the rear of the barrel due to retraction of thecylinder 16. - Moreover, cocking is performed by pushing the
operation member 20 until thelever 17c stops in front, as in the state ofFig. 7A . In this case, thepiston 14 of thepiston cylinder mechanism 15 is positioned in a state of engaging with thetip 29 of thesecond shear 27. In addition, thelever 17c returns to the lower position and therecess portion 17a comes above theindicator lock 32. Therefore, thetip portion 32a rises so as to be able to be engaged. Due to advance of thecylinder 16, the bullet B is loaded in a cartridge portion at thenozzle 19 of the tip. - In accordance with advance of the
operation member 20, thepart 30a of theindicator 30 engages with thetip portion 32a of theindicator lock 32 biased upward and is stopped from advancing. As a result, theindicator 30 protrudes slightly rearward beyond thebolt member 21 and is in the protrusion state. As theindicator 30 protrudes, the state of being cocked is clearly grasped in visual and tactual manners. - When the
trigger 22 is operated in a state where cocking is completed, thepiston spring 18 operates, compressed air is generated due to the advance of thepiston 14, and the bullet B is shot due to the generated compressed air (Fig. 7B ). In theshooting mechanism 25, the rear end portion of thefirst shear 24 is lowered in association with an operation of thetrigger 22. Therefore, theengagement portion 33 provided in the rear end portion is lowered and engages with thecounterpart portion 34 of theindicator lock 32. Then, theindicator lock 32 is pushed down. As a result, theindicator 30 advances by theindicator spring 31 and returns to a state of being withdrawn inside thehollow part 21a of thebolt member 21. -
Fig. 8 illustrates a non-operation state after the bullet B is shot. In the state, theindicator 30 is withdrawn and no cocking operation is performed. In other words, the state is the same as that inFig. 6A , and thelever 17c moves to the lower position and returns to the initial state due to the movement. In this manner, according to the present invention, in addition to two states of protrusion and immersion, a third state which is not any of protrusion and immersion is taken. Therefore, a user can clearly grasp each of the states before operating cocking, in the middle of operation, and completion of cocking. - The indicator apparatus according to the present invention is configured as described above and can be compactly embedded in a simulation gun as an extremely small-type indicator. Accordingly, even in a case of a long simulation gun such as a bolt action rifle, the present invention can be executed without requiring a significant change of the internal structure of the simulation gun. Therefore, the present invention is not limited to a rifle-type simulation gun and is easily diverted as a hand gun-type simulation gun, for example.
