Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slide device in a blow-back toy gun having a slide, which is provided in a gun body so as to move rearward of the barrel by gas ejected from a pressure accumulating portion and then move forward.
[0002]
[Prior art]
Blowback toy guns are equipped with a mechanism that uses a gas pressure and a small amount of explosives to fire a bullet and simultaneously retract a slide, reminiscent of the action of a real gun. However, while the actual gun dose is more than enough to blow back the slide, in the case of a blowback toy gun, both the amount and pressure can only be used to a minimum, so when sliding, When the resistance is large, the blowback operation is dull and there is a problem of lack of force.
[0003]
The maximum resistance applied to the slide is caused by slide bleaching, that is, contact between the lower part of the moving body and the hammer. The hammer, or hammer, is caused by a slide during blowback and becomes a cocking state, but it has a triggering spring that opens the valve against the spring force that closes the on-off valve corresponding to the firing needle by the trigger operation. This is a major factor that slows down the backward movement. In order to reduce this resistance, the shape of the slide bleach is rounded, but the effect is not expected.
[0004]
[Problems to be solved by the invention]
The present invention has been made paying attention to the above points, and the problem is to effectively reduce the resistance of the slide caused by the contact with the hammer, thereby obtaining a powerful blowback. is there. Another object of the present invention is to make it possible to reduce the consumption of gas stored in the pressure accumulator.
[000 5 ]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention provides a blowback toy gun having a slide, which is provided in the gun body so as to be moved rearward of the barrel by the gas ejected from the pressure accumulating portion and then moved forward. In order to reduce the contact resistance generated between the hammer and the hammer, a resistance reduction portion is provided on at least one of the slide and the hammer, and the resistance reduction portion is rotatably provided by contact with the hammer or the slide. It is, consisted of those having a song surfaces, mating parts drag reduction unit and it contacts takes initially distant relationship, but during movement of the slide contact, leaving again after the hammer is pressed A measure is taken to assume a positional relationship .
[0006]
The blowback toy gun has a slide provided in the gun body, and the slide is moved rearward by the gas ejected from the pressure accumulating portion, and performs a so-called blowback operation. In the blowback operation, gas is consumed when the slide moves backward (reciprocating), but receives elastic force of the recoil spring R when moving forward (reverse movement) (FIG. 6). S is a spring shaft. Such a blowback toy gun is provided with a hammer, and the hammer is brought into contact with the slide during rearward movement (FIG. 5 or FIG. 1).
[0007]
In order to reduce the contact resistance generated with the hammer due to the forward movement of the slide as described above, a resistance reduction portion is provided on at least one of the slide and the hammer. Resistance reducing portion is provided on the rotation available-by contact with the hammer or slide, consisting of those having a curved surface such as a cylindrical surface or spherical surface. Typical examples of the resistance reduction unit are rollers and balls.
[0008]
It is free to provide a resistance reducing portion composed of rollers and balls on the slide portion or the hammer. Further, the rollers and balls may or may not be pivotally supported. However, when considering that the blowback toy gun is a model of an actual gun, it is desirable to provide the resistance reducing portion by selecting a portion that is invisible or difficult to see from the outside.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. 1 to 5 show a main part of Example 1 in the apparatus of the present invention, and the whole is shown in FIG. In Fig, gas tank 11 is pressure accumulating section, 12 normally closed on-off valve capable of opening and closing the gas outlet, 13 is a gas passage immediately after on-off valve, the front gas passage 14 provided in the slide 21 Gas can be supplied to the rear gas passage 15.
[0010]
The on-off valve 12 is opened via the intermediate member 19 when the hammer 18 moves to the firing operation via the link 17 by the operation of the trigger 16, and then the hammer 18 is caused by the backward movement (forward movement) of the slide 21. It closes again as it is turned on. Reference numeral 12a denotes a valve closing spring, and 18a denotes a firing spring. The latter spring force is stronger than the former spring force. The slide 21 is provided so as to be movable in the front-rear direction by an engagement structure that engages with the slide groove of the gun body 10, and has the spring shaft S provided in the front-rear direction at the front lower portion, and is mounted on the slide shaft 21. The coil spring R is configured to move forward (return).
[0011]
In the lower part of the rear end of the slide 21 having such a configuration, one roller is provided as a resistance reducing portion 23 at a position that cannot be seen from the outside in contact with the front surface 22 of the hammer 18. The illustrated roller is rotatably provided on the slide side by a central shaft 24.
[0012]
Now, in a state where the pressure accumulating unit 11 is filled with gas and the bullet loading unit 25 is loaded with the bullet 26 (FIG. 1), when the trigger 16 is pulled, the hammer 18 rotates and gas is released from the opened on-off valve 12. Is discharged into the gas passage 13. The gas moves from the movable valve 27 through the front gas passage 14 and moves the bullet 26 loaded in the bullet loading section, and on the other hand, flows into the cylinder 28 through the rear gas passage 15 and pressurizes the piston 29, 29 is in a state where the slide 21 integrated with 29 can start moving backward (forward movement) (FIG. 2).
[0013]
The bullet 26 is fired from the barrel 31, and the movable valve 27 closes the front gas passage 14. Simultaneously, as shown in FIG. 3, the blowback starts and the slide 21 moves rearward. As a result , the breach portion 21b of the slide 21 is moved. The state comes into contact with the front surface of the hammer 18. At this time, since the breach portion 21b of the slide 21 is provided with a roller, the hammer 18 is pressed with a light resistance force using the roller as the resistance reduction portion 23. Since the roller slides on the hammer front surface 22 during the backward movement of the slide 21, the hammer 18 is smoothly raised and locked by the shear 32 to be in a so-called cocking state (FIG. 4).
[0014]
During this time, the on-off valve 12 closes, but the slide 21 continues to move backward to the limit position due to inertia (FIG. 5). In the illustrated example, since the lower end of the roller is positioned below the lower surface of the slide 21, the resistance reducing portion 23 does not contact the slide 21 after passing through the hammer 18 and does not become a resistance. Is also significantly reduced.
[0015]
Although Example 1 constitutes a device in which the resistance reduction unit 23 is provided at a position where it cannot be seen from the outside of the slide 21, a configuration opposite to this is possible, and an example thereof will be described with reference to FIG. 7. The example 2 shown in FIG. 7 has a configuration in which the hammer 33 is accommodated in the rear cavity portion 35 of the slide 34, and contacts the front surface of the hammer 33 by the slide breach 36 at the front end of the cavity portion 35. A roller is rotatably supported by a support shaft 38 as a resistance reducing portion 37 on the front side of the hammer 33.
[0016]
In the second example in which the hammer 33 is pushed, the form of the firing spring 33a is different from that in the first example, and there are other differences in shape and structure, but the basic configuration may be common to the first and second examples. The reference numeral is used for and a detailed description is omitted. In the case of Example 2, the roller of the resistance reduction unit 37 is completely hidden inside the slide 34.
[0017]
As shown in Example 1 and Example 2, in the slide device of the present invention, the slides 21 and 34 are smoothly moved by the resistance reducing portions 23 and 37 such as rollers. Simultaneously with this significant reduction in resistance, the impact at the time of contact is alleviated, so the impact sound is also reduced. In particular, when it is desired to reduce the impact or impact sound, it is preferable to use a resin material having elasticity for the contact portions of the resistance reduction portions 23 and 37 with the hammers 18 and 33 or the slides 21 and 34.
[0018]
【The invention's effect】
Since the present invention is constructed and operates as described above, the resistance accompanying the blowback of the slide caused by the contact with the hammer can be remarkably reduced. Since the gas consumption is reduced as the resistance decreases, the gas consumption is reduced from the muzzle even when used outdoors in winter or when a trigger operation without a bullet is performed. This contributes to the extension of the gas replenishment interval in a toy gun or the like that emits gas.
