Technical Field
[0001] The present invention relates to a trigger apparatus in a simulation gun in which
a shear in a state of cocking is released in response to an operation of a trigger.
Background Art
[0002] 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. However, even if the shape and the
operability can be equal to those of a real gun, it is natural to have internal mechanisms
different from each other.
[0003] The simulation gun and the real gun are essentially different from each other. Nevertheless,
there are common demands of users. For example, there are demands related to a shooting
device called a trigger or a gunlock, particularly related to operation feeling. Similar
to the real gun, the simulation gun also demands accurate operability and high bullet-collecting
characteristics.
[0004] In a case where the operation feeling is not appropriate when the trigger is operated,
shaking occurs, leading to a result in which a planned shooting record cannot be achieved.
[0005] The applicant of this case has grasped this point as a technical problem to be solved
from the related art and has formerly proposed the invention of
JP-A-2005-114260. The invention of the literature discloses a gun which is enabled to shoot a bullet
by a lighter operation even in a case of a simulation gun using a strong spring or
the like. The invention has a configuration in which an intermediate member is moved
to a different position due to leverage when the gunlock is pulled, and thereby latching
by a shear member is released.
[0006] However, the so-called intermediate member of the invention is a part of the shear
member, and an engagement portion at the rear end thereof is configured to be applied
to an upper portion of the gunlock as a load. As a result, in a state where cocking
is completed, a force pressurizing a piston in a piston cylinder mechanism is easily
applied to the gunlock via the shear member and the intermediate member. The load
acts when the gunlock is operated, and the load is sensed as resistance. Therefore,
leaving a comparison with existing guns aside, there is a possibility of insufficient
feeling for the demands such as improving more delicate operation feeling.

Summary of Invention
Technical Problem
[0008] The present invention has been made in consideration of the foregoing points, and
an object thereof is to further improve operation feeling of a trigger in a simulation
gun. In addition, another object of the present invention is to provide a trigger
apparatus in a simulation gun in which delicate operation feeling can be adjusted
by a user himself/herself.
Solution to Problem
[0009] In order to attain the above-described objects, according to the present invention,
there is provided means for a simulation gun having a configuration in which a shear
in a state of cocking is released in response to an operation of a trigger, in which
an intermediate member disposed between the trigger and the shear is rotatably and
pivotally supported by a gun main body, the intermediate member is interlocked so
as to be able to be interlocked and be released with respect to the shear on a rotary
end portion side separated from a pivotal support point thereof, and an operation
force of the trigger acts on a spot between the pivotal support point and an interlocking
point with respect to the shear. Operation feeling in the present invention includes
quite sensuous feeling such as so-called pulling feeling and an applying condition
of the trigger. However, technically, the operation feeling is considered to be easiness
of grasping the applying timing of the trigger in which a force and a stroke required
for an operation of the trigger are involved.
[0010] The present invention has a configuration in which the intermediate member disposed
between the trigger and the shear is rotatably and pivotally supported by the gun
main body. Therefore, the action of the trigger can be replaced by a rotation of the
intermediate member. Accordingly, by selecting an abutting position of the trigger,
the length of a moment arm of an acting point with respect to the intermediate member
can be changed, and a force required to operate the trigger can be arbitrarily set.
[0011] It is desirable for the present invention to have a configuration in which a spring
acts on the intermediate member from a side opposing an operation direction of the
trigger, and an adjustment screw is provided in a place receiving the spring in order
to adjust the strength of the spring. Since a user can operate the adjustment screw
from the outside of a gun, the strength of the spring can be adjusted and the taste
of the user himself/herself can be reflected. Thus, it is possible to obtain a simulation
gun in which using feeling is further improved.
[0012] It is preferable for the apparatus of the present invention to have a configuration
in which the simulation gun includes a piston cylinder mechanism, a force acting in
a pressurizing direction of a piston in response to cocking is added to the shear,
and the trigger acts in an intersecting direction with respect to the intermediate
member receiving the force added to the shear. Since the trigger acts in the intersecting
direction with respect to the intermediate member, by selecting the position of the
acting point, the adding force can be more easily adjusted.
[0013] In addition, it is also desirable to have a configuration in which the shear has
a first shear attached to the gun main body side and a second shear attached to the
first shear, the second shear is interlocked with the piston, the intermediate member
is interlocked with the first shear in order to release the first shear in the state
of cocking in response to an operation of the trigger, and the second shear is separated
from a state of being interlocked with the piston in accordance with separation from
the interlocked state. In other words, the shear can be configured by combining two
members of the first shear and the second shear together. However, the shear in the
present invention does not limit a configuration of a single member.
Advantageous Effects of Invention
[0014] The present invention has a configuration and acts as described above, thereby exhibiting
an effect of being able to more remarkably improve operation feeling of the trigger
in a simulation gun by using the intermediate member disposed between the trigger
and the shear. In addition, according to the present invention, it is possible to
allow a user himself/herself to be able to manually adjust delicate operation feeling,
and thus, it is possible to provide a trigger apparatus in a simulation gun in which
delicate operation feeling suitable for each of users can be individually obtained.

Description of Embodiment
[0016] 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 a shooting device section 11 embedded in a gun main body, a
barrel section 12 positioned in the front portion thereof, and a stock section 13
positioned in the rear portion of the shooting device section 11.
[0017] The shooting device section 11 includes a piston 14 and a cylinder 16 and is provided
with an operation member 20 having a piston cylinder mechanism 15 generating compressed
air for shooting a bullet, a shooting mechanism 25 for controlling a shooting operation
performed by a trigger 22 (will be described later), and a bullet loading mechanism
35. The piston cylinder mechanism 15 has the piston 14 and the cylinder 16, is attached
so as to be movable in a forward/rearward direction of the gun main body, and configures
the front portion of the operation member 20 performing cocking. A bolt member 21
(will be described later) is provided on the rear side of the piston cylinder mechanism
15. In addition, the bolt member 21 configures the rear portion of the operation member
20.
[0018] The operation member 20 including the piston cylinder mechanism 15 and the bolt member
21 is movable in the forward/rearward direction of the gun main body. In order to
operate the operation member 20, an operation handle portion 17 is provided on the
bolt member side. The operation handle portion 17 includes a lever 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. In Figs. 1, 2, and the like, the lever 17c of the operation
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.
[0019] 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, the piston
cylinder mechanism 15 stores pressure due to retraction of the piston 14 inserted
into the cylinder 16 and has a piston spring 18 which causes the piston 14 to advance
due to a release thereof. In addition, the cylinder 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 a nozzle 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 the nozzle 19 when advancing.
[0020] The shooting mechanism 25 controlling the shooting operation described above is rotatably
and pivotally supported by a support pivot 22a on the gun main body side and has the
trigger 22 biased by a trigger spring 22b.
The trigger 22 has an input portion 22c protruding so as to abut an intermediate member
23, on the front side. In addition, the trigger 22 has a trigger screw 22d adjusting
the protruding amount with respect to the intermediate member 23, on the rear side.
The intermediate member 23 is pivotally supported by a support pivot 23a on the gun
main body side and transmits an operation of the trigger 22 to a first shear 24 in
shears made of two members (refer to Fig. 3). The first shear 24 is rotatably and
pivotally supported by a support pivot 24a on the front portion, on the gun main body
side. Springs 23b and 24b respectively act on the intermediate member 23 and the first
shear 24. In addition, the first shear 24 has an engagement portion 33 in the rear
portion and is configured to be interlocked with an interlock counterpart portion
34 of an indicator lock 32 acting on an indicator 30 (will be described later) so
as to be able to be locked in the state thereof.
[0021] A second shear 27 is rotatably and pivotally supported by a support pivot 27a in
the first shear 24.
The second shear 27 is biased so as to protrude in a direction of the piston 14 by
a shear spring 27b. Meanwhile, an engagement portion 28 is provided in the rear portion
of the piston 14 and is configured to engage with a protruding tip 29 of the second
shear 27 at a piston retraction position (refer to Fig. 5). In addition, for engagement
with the piston 14, a slit 16a through which the tip 29 passes is formed in the longitudinal
direction of the lower surface of the cylinder 16.
[0022] As described above, the intermediate member 23 is pivotally supported at the lower
portion on the gun main body side and is interlocked with an interlock counterpart
portion 26 formed in the rear portion of the first shear 24, in an interlock portion
23c formed in the upper portion (refer to Fig. 4). In addition, the intermediate member
23 has the length of the arm such that a gap between the support pivot 23a and the
interlock portion 23c is arbitrarily set. In the embodiment, the input portion 22c
of the trigger 22 is in a state of being able to abut the position approximately half
thereof. Therefore, depending on an abutting position of the trigger input portion
22c, the length of a moment arm from the support pivot 23a of the intermediate member
23 to a force point can be changed, and a force required to operate the trigger can
be arbitrarily set.
[0023] Therefore, while paying attention to that the torque applied to the trigger 22 increases
as the abutting position of the input portion 22c approaches the support pivot 23a
and the length of the arm becomes shorter and the torque applied to the trigger 22
decreases as the abutting position is separated from the support pivot 23a and the
length of the arm becomes longer, and in consideration of a force generated in the
interlock counterpart portion 26 and the interlock portion 23c, the position is set.
Moreover, the strength of the spring 23b acting on the intermediate member 23 is configured
to be adjustable by an adjustment screw 23d. The adjustment screw 23d has fitting
means for an operation performed by a tool such as a wrench and can be adjusted by
inserting the tool into the fitting means. The reference number 23e indicates a blank
space for adjustment and is provided such that a user himself/herself adjusts the
strength of the spring 23b by operating the tool.
[0024] The bullet loading mechanism 35 described above is a part of the simulation gun 10
and is illustrated as a type of mounting a magazine 37 which is attachable/detachable
with respect to a magazine insertion port 36 provided on the gun main body side. The
bullet B is biased forward by a magazine spring 38 from a state of being loaded into
the magazine 37, passes through a bullet feeding section 39, and is fed to a position
at the rear of the barrel.
[0025] An operation of a trigger apparatus in a simulation gun according to the present
invention having such a configuration will be described with reference to the drawings.
Figs. 1 and 2 illustrate a state where a cocking operation is not performed. The lever
17c is at the lower position. Subsequently, the handle lever 17c is operated and is
rotated to the upper position. Then, the operation member 20 is fully pulled rearward,
and the piston 14 is retracted in the piston cylinder mechanism 15. As the piston
24 is retracted, the engagement portion 28 thereof moves to a position so as to be
able to engage with the tip 29 of the second shear 27.
[0026] Fig. 5 illustrates a state where a cocking operation is performed and preparation
for shooting is completed, that is, a state where the engagement portion 28 of the
retracted piston 14 engages with the tip 29 of the second shear 27. Therefore, an
acting force of the piston spring 18 compressing the piston 14 is first applied to
the second shear 27 and is also applied as a load with respect to the first shear
24 in which the second shear 27 is pivotally supported. However, the spring 24b for
returning also acts on the first shear 24, and the load is very small.
[0027] Moreover, the first shear 24 is interlocked at the interlock part between the interlock
counterpart portion 26 provided at the rear end thereof and the interlock portion
23c provided at the upper end of the intermediate member 23. The load also reaches
the intermediate member 23. However, the load is very small and is applied in the
longitudinal direction at the end portion of the rotating intermediate member 23.
Therefore, the load does not significantly affect the operation force of the intermediate
member 23. In this state, a biasing force of the spring 23b acts on the intermediate
member 23 rearward from the front. In addition, the trigger input portion 22c is configured
to be able to be in contact at the rear and is in a state where a biasing force of
the trigger spring 22b acts forward.
[0028] When the trigger 22 is operated in this state, an intermediate part of the intermediate
member 23 in which the very small load and the biasing force of the spring 23b act
is pushed by the trigger input portion 22c. Therefore, an operation force of the trigger
22 becomes light, and the user feels the light operation force and a release of the
interlocked state in the interlock part through fingers as the operation feeling.
The protruding amount of the trigger 22 can be adjusted by the trigger screw 22d.
Accordingly, a stroke for pulling the trigger 22 can also be adjusted to be shallow
and deep. In addition, the strength of pushing the interlock portion 23c against the
interlock counterpart portion 26 can be changed by the adjustment screw 23d via the
spring 23b.
As a result of operating the trigger, the interlocked state between the interlock
counterpart portion 26 and the interlock portion 23c is released, and the first shear
24 is lowered downward. Accordingly, the engagement between the engagement portion
28 of the piston 14 and the tip 29 of the second shear 27 is released (Fig. 6), and
the bullet B is shot.
[0029] The operation feeling includes quite sensuous feeling such as so-called pulling feeling
and an applying condition of the trigger 22 as described above. However, according
to the trigger apparatus in a simulation gun of the present invention, a force required
to operate the trigger 22 is within an extremely light range. In addition, the stroke
can also be short, and the setting conditions acting on the trigger 22 can be changed.
Accordingly, it is easy to feel the delicate timing of applying the trigger 22. Besides,
the setting conditions can be adjusted depending on the necessity of the user himself/herself.
Therefore, according to the trigger apparatus of the present invention, it is possible
to obtain remarkably appropriate operation feeling as appropriate as can be when the
trigger is operated.
[0030] According to the present invention, there are a plurality of adjustment elements
related to the pulling feeling of the trigger 22. The adjustment elements include
an element which is adjusted at the manufacturing stage in the manufacturer, and an
element which is adjusted by a user who has purchased the simulation gun. For example,
the strength of the spring 23b can be changed by the user using the adjustment screw
23d. However, the adjustment is related to the strength of pushing the interlock portion
23c against the interlock counterpart portion 26 and is significantly related to the
pulling feeling of the trigger 22. Thus, according to the present invention, quite
sensuous operation feeling such as so-called pulling feeling and an applying condition
of the trigger can be remarkably improved.
