Description

  The present invention relates to a simulated machine gun imitating impact vibration caused by continuous firing of a machine gun.

  Since continuous firing with a machine gun results in high-speed shooting of about 14 to 17 shots per second, when imitating the impact of this high-speed shooting, the weight is reciprocated at high speed by the rotating cam and spring force normally driven by a motor. An impact vibration having an extremely short period is generated by causing a weight moving by a spring force to collide with a stopper (see, for example, Patent Document 1).

JP 2000-202155 A

  In Patent Document 1, the cam contour formed on the peripheral surface of a cylindrical cam rotated by a motor disengages the weight from the pressing area that pushes the weight forward against the spring force and the weight. There is disclosed a vibration generating device that is formed from a release region in which the weight is returned backward by a spring force, and the released weight collides with a stopper to cause an impact on the gun model.

  If the gun model disclosed in Patent Document 1 shoots at a high speed of about 14 to 17 shots per second, the cam contour of the cylindrical cam is composed of a pair of pressing area and releasing area. The cam will rotate at about 1000 rpm.

  Then, if the weight of the weight is considerably large in order to give a certain impact force to the gun model, the weight moving forward against the spring force by the pressing area of the cylindrical cam rotating at about 1000 rpm is caused by inertia. After moving a little further forward away from the pressing area, it moves backward in the release area by the spring force.

  If the distance from the pressing area to the front is large due to the inertia of the weight, it takes time for the weight to return backward by the spring force and collide with the stopper. It does not collide, it corresponds to the pressing area before it collides with the stopper, and a weight returning at a high speed backward by a spring force collides with the pressing area rotating at high speed almost immediately before colliding with the stopper. .

  Unlike the collision with the stopper, this collision generates a large collision sound due to the collision of metals moving at high speed, and an excessive force is repeatedly applied to the rotating mechanism of the cylindrical cam by the motor, which has an adverse effect.

The collision sound between metals is different from the shooting sound, and this repeated collision sound becomes a loud noise, which makes the player uncomfortable.
Also, the impact when the weight returning by the spring force collides with the rotating pressing area is different from the desired impact when it collides with the original stopper. It becomes heterogeneous and gives the player a sense of incongruity.

  The present invention has been made in view of the above points, and a purpose of the present invention is to simulate a machine gun and a shooting game capable of realizing a desired impact vibration that mimics high-speed shooting of a machine gun by suppressing a collision sound. The point is to provide the device.

  In order to achieve the above object, the invention according to claim 1 is directed to a weight supported so as to be reciprocally linearly movable on a gun body frame, a spring member for urging the weight in one direction, and the spring member. An elastic stopper fixed to the gun body frame that receives the biased weight at a predetermined position, a cam surface that contacts the weight and moves the weight against the biasing force of the spring member, and the weight In a simulated machine gun comprising a rotating cam that is alternately formed with concave surfaces not in contact with a weight and rotated by a motor, the inertia of the weight that moves against the urging force of the spring member in contact with the rotating cam surface The simulated machine gun is provided with a regulating member that regulates the movement by the required position of the gun body frame.

  The invention according to claim 2 is the simulated machine gun according to claim 1, wherein the restricting member restricts movement of the weight via an elastic member.

  According to a third aspect of the present invention, in the simulated machine gun according to the first or second aspect of the present invention, there is provided an adjusting means for adjusting a restriction position of a restriction member for restricting movement of the weight.

  According to a fourth aspect of the present invention, in the simulated machine gun according to the third aspect, the adjusting means is a screw mechanism that moves the regulating member in a perspective direction with respect to the weight.

According to a fifth aspect of the present invention, the simulated machine gun according to the first aspect is disposed in a play box in which a player enters and plays, and a display for displaying a game image is disposed in front of the simulated machine gun. It is a shooting game device characterized.

  According to the simulated machine gun of the first aspect, the restricting member restricts the movement due to the inertia of the weight moving against the urging force of the spring member in contact with the rotating cam surface at the required position of the gun body frame. Therefore, when the weight returns quickly due to the biasing force of the spring member and the concave surface corresponds to the weight, the weight collides with the elastic stopper, simulating the desired shock vibration imitating the high-speed shooting of the machine gun Give it to a machine gun and let the player experience it.

  Therefore, it is avoided that the weight returning by the spring force collides with the rotating cam surface, the impact sound is suppressed and the extraneous vibration is avoided, thereby preventing the player from feeling uncomfortable or uncomfortable. Can do.

  According to the simulated machine gun of claim 2, since the restricting member restricts the movement of the weight via the elastic member, the elastic member receives the weight moving due to inertia, and the collision sound at this time is received. In addition to being able to suppress, it is possible to reliably prevent the weight from colliding with the cam surface by increasing the initial acceleration of the weight and speeding up the return.

  According to the simulated machine gun of claim 3, since the adjusting means includes the adjusting means for adjusting the restriction position of the restriction member for restricting the movement of the weight, the weight is reciprocated by the rotating cam that rotates by driving the motor. While being moved, the regulating position of the regulating member is gradually moved to the weight side by the adjusting means, and can be adjusted to the optimum position where the impact sound is minimized.

  According to the simulated machine gun of the fourth aspect, since the adjusting means is a screw mechanism that moves the restricting member in the perspective direction with respect to the weight, the restricting position of the restricting member is gradually increased by rotating the screw. Since it can be moved to the weight side, and the restriction position of the restriction member does not change due to the collision of the weight, the position adjustment of the restriction position of the restriction member can be easily performed.

According to the shooting game apparatus of claim 5, the simulated machine gun is arranged in a play box where a player enters and plays, and a display for displaying a game image is arranged in front of the simulated machine gun. The player can perform a shooting play while watching the video inside the play box, suppress internal noise, and can enjoy a realistic play without being bothered by extraneous external noise.

  Sliders 61, 61 are provided on the left and right side walls 22L, 22R of the gun body frame 22 in pairs so as to be slidable back and forth along the outer surface. 60 is fixed and the weight 60 is slidably supported back and forth.

  3, 4, and 6, weight 60 has a shape in which left and right side portions 60 b and 60 b and rear side portion 60 c are bent downward while leaving upper plate portion 60 a of a substantially rectangular flat plate. The weight 60 having such a shape spans the upper wall 22U of the gun body frame 22 and houses the rod 36 and the compression spring 40 so as to cover from above, and the left and right side portions 60b and 60b bent downward. The lower ends of the sliders 61 and 61 are fixed to the sliders 61 and 61 located on the inner side by screws 62, and are supported slidably forward and backward together with the sliders 61 and 61.

The rear side portion 60c of the weight 60 is shorter than the left and right side portions 60b, 60b and is positioned close to the upper wall 22U. A rectangular plate-like elastic member is disposed on the rear surface of the rear side portion 60c. 63 is fixed.
A rectangular opening 60d that is long in the longitudinal direction is formed in the center of the upper plate portion 60a of the weight 60, and a latching member 65 is installed at predetermined positions in the rectangular opening 60d. Is fixed to the upper wall 22U by screws 66.

The front end of the central portion of the hooking member 65 is bent downward to form a vertical hooking piece 65a, and the lower end center of the vertical hooking piece 65a is cut out so as to straddle the rod 36.
A rod in which the vertical latch piece 65a of the latch member 65 protrudes forward from the slide piece 41 at the front end of the compression spring 40 when the weight 60 is placed over the upper wall 22U of the gun body frame 22 The sliding piece 41 urged by the compression spring 40 is brought into contact with the rear surface of the vertical latching piece 65a by being fitted into the notch so as to straddle the front end portion of 36, and at the same time, the rear side portion 60c of the weight 60 Is positioned behind the elastic stopper 42 attached to the support member 37 at the rear end of the rod 36, and the inner surface (front surface) of the rear side portion 60 c is opposed to the elastic stopper 42.

The weight 60 is attached to the sliders 61 and 61 in such a posture, and the weight 60 is supported on the gun body frame 22 so as to be slidable back and forth.
Therefore, when an external force is applied to the weight 60 and the weight 60 moves rearward, the latch member 65 pushes the sliding piece 41 rearward to compress the compression spring 40, and when the external force is released, the compression spring 40 The weight 60 moves so as to be bounced forward by the spring force, and the rear side portion 60c of the weight 60 collides with the front elastic stopper 42 facing the weight 60.

  A regulating member 50 is located opposite the elastic member 63 fixed to the rear surface of the rear side portion 60c of the weight 60.

A support shaft 68 is erected on the front left and right central portions of the upper plate portion 60a of the weight 60, and a roller 70 is rotatably supported on the upper portion of the support shaft 68 via a bearing 69.
When the weight 60 is slidably mounted on the gun body frame 22, the roller 70 is at the same height as the rotating cam 32 protruding above the front gun body frame 22 and is attached to the cam follower. It is equivalent.

  When an external force is not applied to the weight 60 and is urged by the compression spring 40 so that the rear side portion 60c of the weight 60 is in contact with the elastic stopper 42 and is located in the foremost position, the rotating cam 32 is shown in FIG. 2, the roller 70 is closest to the rotating cam 32 and is not in contact with the concave surface 33b of the rotating cam 32, but faces the concave surface 33b and is in the concave portion between the cam blades 33 and 33.

7 to 11 show the movement of the weight 60 when the motor 35 is driven and the rotary cam 32 is rotated.
7 is the same as the state shown in FIG. 4, the weight 60 is in the foremost position, and the roller 70 faces the concave surface 33 b of the rotating cam 32.

  When the rotating cam 32 rotates counterclockwise from the above state in this state, the cam surface 33a having a smooth convex surface of the rotating cam 32 comes into contact with the roller 70, and the rotating cam surface 33a is moved to the roller 70 as shown in FIG. Rolls to move the roller 70 together with the weight 60 backward against the spring force of the compression spring 40.

FIG. 9 shows the final state in which the weight 60 is moved backward by the rotating cam surface 33a.
In the state shown in FIG. 9, the weight 60 has inertia due to its own mass, and further moves rearward. In FIG. 10, the elastic member 63 fixed to the rear portion of the weight 60 is rearward. The weight 60 is in contact with the regulating member 50 and the weight 60 is located at the rearmost position.
This movement due to the inertia of the elastic member 63 resists the spring force of the compression spring 40 and does not collide with the restricting member 50 so strongly, so there is not much impact vibration.

Next, as shown in FIG. 11, the weight 60 moves forward by the spring force of the compression spring 40.
The roller 70 also returns to the front together with the weight 60, and the rotating cam 32 also rotates during this time, and the cam blade 33 having the cam surface 33a in contact with the roller 70 is further rotated, and the concave surface 33b Laura 70 is facing.

Therefore, the roller 70 in the return (advance) state does not collide with the rotating cam blade 33, but the rear side portion 60c of the weight 60 collides with the elastic stopper 42, so that the roller 70 is in the foremost position. Return to the state shown in FIG.
The gun body frame 22 is subjected to impact vibration by the collision of the weight 60 with the elastic stopper 42.

The motor 35 is driven so that the rotary cam 32 rotates at a high speed of about 250 rpm.
Since the rotating cam 32 rotates four cam blades 33, the weight 60 is reciprocated approximately 1000 times per minute, which generates impact vibration 16 to 17 times per second, and the actual engine The impact vibration of high-speed shooting of about 14-17 shots per second by a gun can be imitated.

  In the present embodiment, the regulating member 50 provided at the rear of the weight 60 forcibly stops moving in the middle due to the inertia of the weight 60, so the weight due to the spring force of the compression spring 40 When the return of 60 is accelerated and the roller 70 returns to the original foremost position, the rotating cam 32 is still in contact with the next roller 70 until the cam surface 33a of the cam blade 33 that moves backward contacts the roller 70. The state shown in FIG. 7 can be obtained.

  If there is no restriction member that restricts the backward movement due to the inertia of the weight 60 as in the conventional case, the return of the weight 60 due to the spring force of the compression spring 40 is delayed, and the roller 70 is returned to the original foremost position. Before returning, the cam surface 33a of the cam blade 33 that moves backward in contact with the next roller 70 of the rotating cam 32 collides.

  Since the roller 70 moving forward by the spring force of the compression spring 40 and the cam blade 33 of the rotating cam 32 rotating at high speed collide with each other at high speed, a large collision noise is generated. Unlike the shooting sound, this repeated collision sound becomes a loud noise, and if it is played in the play box 1 that is kept silent if no sound is generated, the repeated collision sound between the metals is Sounds greatly and gives the player discomfort.

  In the present embodiment, since the restriction member 50 is provided, the collision between the roller 70 and the cam blade 33 that is in the forward return state is avoided, so that the repeated collision noise between the metals does not occur, There is no discomfort to the player in the play box 1.

  In addition, since the sound imitating the high-speed shooting sound is emitted from the speaker 9, the player receives the shock vibration of the high-speed shooting like when shooting a machine gun from the simulated machine gun 20, and imitates the high-speed shooting sound. Because you can listen to the sound, you can enjoy a realistic play without being bothered by extra noise.

  The position of the regulating member 50 that regulates the backward movement due to the inertia of the weight 60 on the way controls the relative positional relationship between the rotating cam 32 that rotates at high speed and the roller 70 that reciprocates at high speed. It is not easy to determine the optimum position of the regulating member 50 on which the rotary cam 32 and the roller 70 operate in the relative positional relationship as shown in FIGS.

Therefore, in the present embodiment, there is provided an adjusting means that can set the front-rear position of the regulating member 50 to the optimum position.
That is, a screw mechanism is provided by an adjustment screw 58 that moves the regulating member 50 forward and gradually approaches the elastic member 63 at the rear of the weight 60.

  When adjusting the front / rear position of the restricting member 50, first loosen the bolts 51 and 52 to allow the restricting member 50 to move forward and backward, and then turn the adjusting screw 58 counterclockwise (retracting backward). Then, the forward protrusion amount is reduced, the adjustment screw 58 is moved to a considerably rear position, the motor 35 is driven, the rotary cam 32 is rotated, and the weight 60 is reciprocated.

  Initially, since the regulating member 50 is located considerably rearward, even if the backward movement due to the inertia of the weight 60 is not restricted or restricted, it is just before the weight 60 returns, and the weight 60 is moved to the foremost position. Since the return is slow, the roller 70 in the return state and the cam blade 33 of the rotating cam 32 repeatedly collide with each other to generate a loud collision sound between the metals.

  Here, when the adjustment screw 58 is rotated clockwise by the driver, the amount of protrusion of the adjustment screw 58 to the front is increased, and the regulating member 50 is gradually moved forward, the inertia 60 of the weight 60 By gradually regulating the backward movement and gradually returning the weight 60 to the foremost position, the cam blade 33 collides around the foremost position of the roller 70, and the collision is mitigated. The collision sound between metals is gradually reduced.

  When the adjusting screw 58 is further turned clockwise to move the restricting member 50 forward, the collision sound between the metals gradually disappears, and the place where the most difficult to hear is at the optimum position of the restricting member 50. Here, the restricting member 50 is fixed by tightening the bolts 51 and 52.

  In this way, the adjustment screw 58 is rotated while listening to the collision sound to find a place where the collision sound is minimized, so that anyone can easily adjust the regulating member 50 to the optimum position. .

  Since the adjusting means is a screw mechanism with the adjusting screw 58 that moves the regulating member 50 in the direction to bring the regulating member 50 closer to the weight 60, the regulating position of the regulating member 50 is gradually moved to the weight 60 side by rotating the adjusting screw 58. Since the restriction position of the restriction member 50 does not change due to the collision of the weight 60, the restriction position of the restriction member 50 can be easily adjusted and the workability is good.

In the above embodiment, the rotating cam 32 is composed of four blade cams 33, but it is also possible to use one blade cam or a rotating cam of a plurality of blade cams other than four.
However, in order to simulate high-speed shooting of about 14 to 17 shots per second, when there are n blade cams, a rotational speed of about 1000 / n rpm is required.

  That is, when there is one blade cam, the rotational speed is about 1000 rpm, when it is two, the rotational speed is about 500 rpm, when it is three, the rotational speed is about 333 rpm, and when it is five, the rotational speed is about 200 rpm. Set the rotation speed of the rotating cam.

  In addition, when using the rotating cam which consists of 5 or more blade cams, since the width | variety between adjacent blade cams becomes narrow, you have to design so that the roller corresponded to a cam follower may enter in the recessed part between blade cams.

  In the above-described embodiment, the motor 35 and the rotating cam 32 are provided in the gun body case 22 and provided in the weight 60 that reciprocates the roller 70 that is a cam follower. Conversely, the motor and the rotating cam are disposed on the weight side. A roller may be provided on the gun body case side.
