Abstract

By separately installing the movable portion and the weight of the piston cylinder, a recoil shock equivalent to increasing the piston weight without increasing the piston weight is obtained. In addition, the same recoil shock as that of the actual gun is obtained without damaging the appearance of the gun.

Due to the operation of the movable part of the piston cylinder generating compressed air, the weight is driven to provide a simulated recoil, that is, a recoil shock, while providing a contact part 31 which is moved in the retracting direction by the movable part 13. The recoil spring 35 is compressed by receiving the force transmitted to the weight 33 through the contact portion 31 by the movable portion 13, and the recoil spring 35 is compressed, after which the recoil spring is compressed. The reaction accompanying the movement of the weight 33 when the 35 is stretched by the elastic force is configured to be transmitted to the gun body 37 as a recoil shock.

TECHNICAL FIELD The present invention relates to an apparatus in which a weight is driven due to the operation of a movable part in a piston cylinder device that generates compressed air, thereby obtaining a simulated reaction.

Attempts have been made to reproduce the simulated recoil (recoil shock) in the toy gun in the same manner as the actual gun that generates the recoil at the time of bullet shooting. The recoil applying method found in commercially available toy guns is such that a shock is obtained by weighting the piston with respect to a toy gun having a piston cylinder that generates compressed air. For this reason, in order to obtain sufficient shock, it is necessary to make the piston heavy, and if the piston is heavy, it is necessary to reinforce the piston spring in order to avoid the drop of the bullet speed. There has been a problem that the shock damages the cylinder head, the piston itself, the operating mechanism, or the like, which significantly impairs durability.

In some of the applied documents, as in Japanese Patent Laid-Open No. 2000-88494, the piston rod is projected by a triggering operation, and the movable shoulder rest is projected rearward to impact the shooter's shoulder. There is a disadvantage that must be given a mechanism that does not exist in the actual gun. In addition, Japanese Patent Laid-Open No. 8-89661 applies a recoil by driving a slide cover by a solenoid linked with a trigger operation, but is not suitable for a rifle type having no slide mechanism. In addition, Japanese Unexamined Patent Application Publication No. 6-22793 uses a shock generated backward by a spring and a weight along the barrel to press the air chamber, and fires a bullet of the air gun at that pressure. It is a special thing and is not generally suitable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and the problem is to provide a recoil shock equivalent to increasing the piston weight without increasing the piston weight by separately installing the movable portion and the weight in the piston cylinder device. In addition, another object of the present invention is to make it possible to experience the same recoil shock as the actual gun without harming the appearance of the actual gun.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention is a device which drives the weight and obtains a simulated reaction by the operation | movement of the movable part in the piston cylinder apparatus which produces compressed air. At the same time, the liaison part is installed, and the movable part is provided with a recoil spring that is compressed to receive the force transmitted to the weight through the liaison part, and the recoil spring is compressed and then moved to the weight when it is stretched by elastic force. Means have been taken to ensure that the accompanying reactions are transmitted to the gun body.

The toy gun of the present invention relates to a gun in a manner of generating compressed air using a piston cylinder device. The piston cylinder device is generally a type in which the piston slides in the cylinder, but there are also types in which the piston is fixed and the cylinder is movable. In either case, the piston and the cylinder are both movable parts, Driving weight is a subject of the present invention.

In toy guns in which compressed air is produced by the piston cylinder device, compressed air can be used for firing bullets. However, needless to say, even when the bullet is not fired, the piston can obtain a simulated reaction when the weight is driven due to the operation of the cylinder. Therefore, for the recoil shock that accompanies bullet firing, the simulated recoil according to the present invention is not subject to bullet firing. That is, the apparatus of the present invention can be applied not only to having a bullet launch mechanism but also to having no bullet launch mechanism.

In the apparatus of the present invention, a contact portion capable of moving in the retraction direction is provided based on the operation of the movable portion constituted by either the piston or the cylinder. The contact portion serves to transmit the force exerted by the movable portion to the weight, and the weight is combined with a recoil spring that is subjected to the force and is compressed. In other words, the force is transmitted in the order of “moving part → contact part → weight → recoil spring”. However, since each part of the movable part, the contact part, and the weight moves in the same direction and is about the same length, it is divided into three parts. This is not an absolutely necessary condition, but corresponds to the fact that the number and structure of parts can be arbitrarily changed by design.

Such a movable portion, the contact portion and the weight may take the configuration of being arranged almost straight in this order, which arrangement is suitable for a gun such as a rifle having a gun butt of a sufficient length behind the engine portion. In addition, the contact portion may be arranged at a position where a portion thereof is retracted by the movable portion, and may be configured to be connected to the weight at another portion of the contact portion that extends in parallel with the moving axis of the movable portion. Or it is suitable when the apparatus is installed on the left and right or above. The engine section includes up to a long section that is held from the piston cylinder device for firing the bullet.

Either or both of the contact portion and the weight, or between the movable portion and the contact portion, may be provided with an elastic body that becomes compressed by the backward movement of the contact portion. According to the above description, since the force generated in the piston cylinder device is transmitted to the movable part → the contact part → the weight, the transmission action can be changed to the indirect one, not directly, by interposing the elastic body between the contact part and the weight. In addition, although the transmission time is weak, a gap is generated. In addition, the elastic body absorbs the shock accompanying the transfer of force between the piston, the contact portion, and the weight, and also serves to prevent breakage.

In addition, the recoil shock starts when the force exerted by the piston cylinder is transmitted to the weight to compress the recoil spring, and becomes remarkable as the weight advances along with the recoil spring that is elongated by the elastic force. Therefore, in the present invention, the weight retreats according to the compression of the recoil spring, and then the weight of the weight is synchronized when the movable part is moved forward, so that even a slight movement of the weight can realize a recoil shock like a real gun. have. The recoil shock is off the fast side when the spring is strong and late when it is weak.

(The best form to carry out invention)

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiment. 1 to 4 show an example 1 of the toy gun 10 to which the present invention is applied, and has a configuration of a so-called electric gun having an electric launch unit. The illustrated piston cylinder device 11 has a fixed cylinder 12 and a piston 13 sliding therein, the piston 13 being a movable part, the piston 13 being a piston supported on the engine room rear wall. It is shot in front by the spring 14.

Here is a brief description of the electric launch unit. The illustrated projecting part has a rack 15 provided in the front and rear direction at the lower part of the piston, and the retracting (accumulation) of the piston is performed by one rotation of the sector gear 16 which is composed of a tooth part engaged with it and a toothless part for quick return. By advancing (compression of air by releasing the accumulated pressure), the sector gear 16 is driven by the motor 17 via the reduction gear set. The motor 17 is turned on and off by the switch 19 switched by the operation of pulling the trigger 18. In the sector gear 16, the pin 21 is planted and installed toward the side, and the contact member 23 having the engaging portion 22 which retracts the required dimension by engaging with it extends in front of the cylinder. (12) The nozzle 24 at the front end is temporarily retracted so that the bullet 25 can be supplied to the long shot portion 26 one by one. These piston cylinder devices 11, the electric launcher, and the long shot 26 constitute the engine 20. As shown in FIG.

In the rifle-type toy gun 10 shown in Figs. 1 to 4, the recoil shock device 30 according to the present invention is almost in a straight line on the moving axis of the piston 13 or the rear of the piston 13, which is a movable part. It is arranged. That is, the rod-shaped contact portion 31 which is moved in the retraction direction by the piston 13, which is the movable portion, is provided in the thrust bearing 27 provided on the rear wall of the engine room so as to be able to move forward and backward. The front end is contactable with the piston 13, and the rear end of the contact portion 31 is fitted into the guide hole 32 formed in the front portion of the weight 33. As shown in FIG. The elastic body 34, which is interposed between the contact portion 31 and the weight, is made of a small spring disposed in the guide hole 32, and is a recoil spring that is compressed under the force transmitted to the weight 33 ( 35 is disposed at the inner rear end of the case 36 in which the recoil weight 33 is placed.

In the recoil shock device 30 of Example 1 having the above-described configuration, when the trigger 18 is pulled out, the motor 17 rotates, and the piston 13 starts retreating, no piston spring 14 is used. Although it retreats without receiving resistance, when the piston 13 contacts the rod which is the contact part 31, the contact part 31 will receive resistance in a retraction direction (FIG. 2). However, the contact portion 31 compresses the elastic body 34 at the rear end, and when further retreating thereafter, compression of the recoil spring 35 is started, and the load of the weight 33 at the compression limit is total body side 37. Will be transmitted to (FIG. 3). When the compression limit is exceeded, the recoil spring 35 is changed into the stretched state by the elastic force, whereby the weight 33 advances, and the reaction is felt by the shooter as a reaction (Fig. 4). This recoil shock occurs intermittently while pulling the trigger 18.

5 and 6 show an example 2 of the apparatus 40 according to the present invention, in which the weight 43 is incorporated into the space 47 provided in front of the engine unit 20. In this example 2, the contact part 41 is arrange | positioned in the position which one end 49 is retracted by the piston 13 which is a movable part, is formed in the hook shape which can be engaged, and the other end 48 is a weight ( It extends in front of 43, is inserted in the guide hole 42, and is connected to the stopper via the elastic body 44. As shown in FIG. Therefore, the force accompanying the movement of the piston 13 in the retraction direction pushes the weight 43 from the front to the back, thereby compressing the recoil spring 45. The weight 43 of Example 2 is a configuration in which the weight 33 of Example 1 slides inside the case 36, while being inserted outside the barrel 46 and sliding.

The other configuration is the same as that of Example 1, and therefore, the operation of the apparatus 40 of Example 2 will be described using the reference numeral of Example 1. In Example 2, when the rear end engages with the one end 49 of the contact part 41 by the retraction of the piston 13 which is the movable part, the weight 43 is moved in the retreat direction, so that the recoil spring 45 It will be in the state which compresses (FIG. 6). Then, after the recoil spring 45 is compressed, the recoil spring 45 is changed to the stretched state by the elastic force, and in the process in which the recoil spring 45 is compressed to reach the stretched state, the movement of the weight 43 is performed. Reaction becomes a shock of reaction and is felt by the shooter.

7 and 8 show an example 3 of the apparatus 50 according to the present invention, in which the weight 53 is incorporated into a space 57 provided above the engine portion 20. In Example 3, the contact part 51 is arrange | positioned at the position where the one end 59 is retracted by the piston 13 which is a movable part, and is formed in the hook shape which can be engaged, and the other end 58 is the weight ( The inside of the guide 53 enters the guide hole 52 which is movable in the front-rear direction, and the weight 53 is provided in the retreat direction through the elastic body 54. The force accompanying the movement of the piston 13 in the retraction direction pushes the weight 53 backward, thereby making the recoil spring 55 compressible. In the case of Example 3, the weight 53 is slidably installed in the front-rear direction in the constituent wall surface of the space 57 between the engine part and the inside of the main body, or in the receiving portion that is the same as the space 57. All.

In Example 3, when the rear end engages with the one end 59 of the contact portion 51 to generate resistance by the retraction of the piston 13, which is the movable portion, the weight 53 is moved in the retreat direction so that the recoil spring It is in a state of compressing 55. After exceeding the compression limit of the recoil spring 55, the recoil spring 55 is elongated by elastic force, and in the process of reaching the elongation from compression of the recoil spring 55, the reaction of the movement of the weight 53 This recoil shock is felt by the body. The timing of this recoil shock can be adjusted according to the strength of the recoil spring.

(Industrial availability)

The shock by driving the weight with the force transmitted from the movable portion of the piston cylinder device is amplified or offset.

Since the present invention is constructed and functioned as described above, by driving the weight by the recoil spring separately from the movable portion of the piston cylinder and the weight, a recoil shock equivalent to the increased weight can be obtained without increasing the piston weight. The remarkable effect of not impairing the appearance of the film can be obtained.
