BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine loaded with bullets, and more particularly, to a non-tank spring magazine that is mounted on a simulated firearm for a survival game or a war simulation game and supplies a BB bullet by the spring force.

The war simulation game represented by survival game is attracting attention as a leisure sport due to its purifying instinct for human war as well as being very effective for mental and physical training and relieving stress, and the enthusiasts enjoying it are steadily increasing. Particularly, survival game is to perform various military operations by firing BB bullets or paintballs with simulated firearms at game sites equipped with mountainous combat terrain or simulated city areas. Generally, it is manufactured to mimic the appearance of practical equipment.

Among the main equipments used in such survival games or war simulation games, firearms are used to mimic military rifles, and plastic BB bullets of 5 to 6 mm in diameter are used, or 6 mm to 5 cm in diameter. Paintballs are used that are intended to explode the paint in the poem. If BB ammunition is used, the ammunition for feeding the BB ammunition into the firearm is required. The ammunition for the BB ammunition is classified into spring type and spring type depending on the operation method. The manual spring has more than 190 shots and more than 130 springs, but the BB bullets and the inner wall of the magazine collide with each other. On the other hand, the spring type has the advantage that there is no noise and once loaded, it is not necessary to perform additional actions for the supply of coal, but there is a disadvantage that it is insufficient to satisfy the desires of gamers due to the lack of long bullets.

On the other hand, with reference to the accompanying drawings, a representative example of a conventional spring type magazine for BB bullets in relation to the present invention in detail as follows.

As shown in Figure 1, the spring magazine for the BB bullets is composed of an inner body (1) and an outer body (2), the inner body (1) is the ABS of the left half and the right half are assembled by screws It is made of a resin material, the outer body 2 is made of a steel material, such as a practical magazine. The outer body 2 only serves as an exterior material to make the magazine look the same as the actual gun, and the inner body 1 functions as a BB bullet loading space. After inserting the inner body 1 from the upper opening 2c of the outer body 2 into the inside, the fastener 1b is provided in the fastening holes 1a and 2a formed at the lower ends of the bodies 1 and 2, respectively. 2b) is combined to form a completed magazine, in this state BB bullets into the BB bullet loading groove (see Fig. 2) of the inner body 1, and then the magazine is mounted on the mounting holes of the gun Will be used.

On the other hand, looking at the configuration for charging the BB bullet, as shown in Figure 2, the BB bullet charging groove (1c) wound around the inner surface of the inner body 1 once in a track (track) form is It is formed, the BB bullets 3 are charged into the charging groove 1c, and the spring pushing the BB bullets 3 so that the BB bullets 3 are loaded one by one into the chamber of the gun in the charging groove 1c. (4) and the pusher 5 are provided together. In particular, as shown in Fig. 3, the spring 4 is a spring having a generally longitudinal cross section, commonly referred to as a square spring, made of equal pitch, and having a pusher 5 and a spring guider 6 at both ends thereof, respectively. ) Is inserted.

Referring again to FIGS. 1 and 2, a spring insertion opening 1d for inserting the spring 4 into the BB bullet insertion groove 1c is formed at one side of the inner body 1, and the spring 4 is provided. The spring 4 is pushed into the spring insertion hole 1d from the distal end of the pusher 5 in the state in which the pusher 5 and the spring guider 6 are fitted at both ends thereof. In the process of inserting the spring 4, as shown in FIG. 4, the spring guider 6 is placed on the distal wall of the charging groove 1c after the end portion of the spring guider 6 is completely inserted into the spring insertion hole 1d. It is seated while abutting, and is fixed by fastening the protruding end 6a formed on one side of the spring guider 6 with one part around the spring insertion hole 1d and the screw 1e.

By the way, the conventional spring-type magazine for the BB bullets configured as described above has the following problems.

First, the conventional spring type magazine for the BB bullets is only about 60 to 130 shots to charge the BB bullets 3, so the consumption cycle of the BB bullets 3 is faster and the magazines must be frequently replaced during the game. There is. That is, there are two elements that hinder the spring force of the spring 4 in the charging groove 1c, which is the length of the charging groove 1c and the loading groove 1c are tracked in the inner body 1. The number of times wound in a form (hereinafter, defined as 'round'). If the total length of the charging groove 1c is long, the number of rounds of the charging groove 1c cannot be increased, and if the number of rounds is increased, the overall length of the charging groove 1c cannot be increased. In addition, since the spring 4 for applying the resilience force for feeding the BB bullet 3 is made of equal pitch, the spring 4 smoothly applies the BB bullet 3 even if the length of the charging groove 1c is long. Since it will not be able to give a uniform elasticity enough to be able to supply, it is inevitably limited to the length and the number of rounds of the charging groove (1c). Therefore, the length of the BB bullet charging groove 1c formed in the inner surface portion of the inner body 1 may be designed to be short or the number of rounds may be less than two times. This results in a qualifier. Furthermore, since the game magazine is a replica product, since the magazine and the exterior size and shape of the actual gun must be the same, the length and the number of rounds of the charging groove 1c cannot be lengthily increased or increased.

Second, the BB bullets 3 are charged in a substantially zigzag stacked structure in the charging groove 1c of the inner body 1, and pushes the BB shells 3 while contacting the BB shells 3 as shown in FIG. The pushing portion 5a of the main pusher 5 has a spherical shape unlike the laminated structure. Therefore, when the elastic force of the spring 4 is applied to the BB bullets 3 are not uniformly pressured, there is a problem that the supply of the BB bullets 3 is not made smoothly. In addition, since the pushing portion 5a of the pusher 5 and the BB bullet 3 cannot be contacted at equal pressure, the pusher 5 is inclined to one side in the charging groove 1c as shown in the figure. While scratching the inner wall of the charging groove (1c) will cause a malfunction.

Third, when maintenance is required due to an operation error of the magazine, when the spring 4 and the spring guider 6 are separated from the inner body 1, the spring guider 6 is attached to one portion around the spring insertion hole 1d. It is inconvenient to remove the screw 1e that is fastening. In addition, since the material of the inner body 1 is generally made of ABS resin, when the fastening / disassembly of the screw 1e is frequently performed, the screw fastening portion is damaged, and later, a fastening failure occurs and the spring 4 is inner. There is a problem of leaving the body (1).

Fourth, when the spring 4 is compressed in the BB bullet charging groove 1c because the length of the insertion portion 6b of the spring guider 6 fitted to one end of the spring 4 is very short. Unevenness occurs while compressing along the curved shape mainly of the charging groove 1c, and this unevenness pushes against the inner wall of the charging groove 1c, which causes a problem of preventing smooth compression. This will cause a supply failure.

As described above, the conventional spring-loaded magazines for BB bullets have various problems. Therefore, in order to smoothly progress the survival game and the war simulation game and to double the interest, these problems need to be solved.

The present invention has been made to solve the above-mentioned conventional problems, the main object of the spring type for the BB bullets to supply the BB bullets by the spring force is mounted on a simulated firearm for survival games or war simulation games Provides magazines, but maximizes the amount of BB bullets to eliminate the inconvenience caused by frequent replacement of magazines during the game, and to make the BB bullets load and replenish very smoothly.

A secondary object of the present invention is to provide a spring type magazine for a BB bullet which is easily maintained in case of an operation error of the magazine.

Technical configuration of the present invention for achieving the above object is disclosed as follows.

First of all, the basic configuration of the present invention, the charging groove formed in the inner surface portion so that the bibtan is charged from the charcoal opening and the spring insertion port leading to the charging groove and inserted into the charging groove through the spring insertion hole to give a resilience for feeding the bibitan It consists of an inner body each having a spring, and an outer body having an inner space opened to insert and couple the inner body. Here, as a feature for achieving the main object of the present invention, the inner body is formed so that the front and rear size in accordance with the internal space front and rear size of the outer body, the charging groove is the inner surface portion of the inner body from the bullet holes It has a structure formed of two or more rounds in the spring, the spring is made of an uneven pitch spring in which a part of the pitch interval narrower than the remaining portion from the rear end portion in contact with the innermost end of the charging groove. In addition, the pitch of the portion where the pitch interval of the spring is narrow is preferably made 70 to 80% with respect to the pitch of the remaining portions. In addition, it is preferable that the spring has a structure in which the pitch interval is narrower than that of the other portions of the portion extending from 10 to 60% of the entire spring length from the rear end portion which is in contact with the innermost end of the charging groove.

On the other hand, in order to achieve the secondary object of the present invention, there is provided a spring guider is inserted into the rear end of the spring and seated on the innermost end of the charging groove through the spring insertion hole, the spring insertion hole is any of the left and right sides of the inner body It is formed on one side, and the other side of the left and right sides of the inner body is disclosed a configuration in which the removal hole for removing the spring guider through the spring insertion port by pressing the spring guider. In particular, a seating protrusion having an inclined surface toward the spring insertion opening is formed at the innermost end of the charging groove in which the spring guider is seated, and an inclined surface is also formed at the rear end of the spring guider in contact with the inclined surface of the seating protrusion. When the spring guider is removed using a sharp tool, the spring guider may slide off the inclined surface of the seating protrusion and be removed out of the spring insertion hole. In addition, the insertion portion of the spring guider to be fitted to the rear end of the spring, it is preferable that the spring is formed long enough so that the spring does not protrude out of the spring insertion hole when the spring is compressed. In addition, the insertion portion of the spring guider, it is preferable that the corner portion is rounded so that the spring is not caught when the spring is compressed.

And, the pusher is inserted into the front end of the spring and the pusher pushes the bitter bite toward the janggu by the elastic force of the spring while contacting the bitter bullet in the charging groove, the pushing portion of the pusher in contact with the bitter tongue is zigzag in the charging groove Since the configuration is made in accordance with the laminated shape of the bibitan to be stacked in, it can be prevented that the pusher is biased to any one of the inner wall of the charging groove when the bibtan is pushed up by the elasticity of the spring to prevent the occurrence of a sudden supply failure.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

Figure 6 is an exploded perspective view of the inner body and the outer body constituting the spring type magazine for BB bullets according to the present invention. As can be seen in the drawings, the present invention is combined with the inner body 100 having a BB bullet loading groove and the outer body 200 serving as an exterior material to look like a real gun magazine to function as a practical ammunition container. By doing so, you'll be able to build a BB magazine for survival or war simulation games. In particular, a space is provided inside the outer body 200 and an upper end thereof is opened, whereby the inner body 100 is inserted into the inner space of the outer body 200 through the opening 210, and the inner body 100. The lower end of the outer body 200 is fixed with a fastener. It should be noted that in the conventional inner body, since the number of rounds of the charging grooves is formed less, the front and rear size x of the inner body is equal to the inner space front and rear size x 'of the outer body, as shown in FIG. It is formed much smaller than this, because when the inner body flows in the front and rear direction when inserted into the outer body, a projection (1f) for preventing this is formed on the rear portion of the inner body, but in the inner body 100 of the present invention There is no projection. That is, the inner body 100 of the present invention is enlarged and formed larger than the conventional inner body such that the front and rear size y of the outer body 200 corresponds to the internal space front and rear size y 'of the outer body 200. Since the body 100 fits into the inner space of the outer body 200, the protrusion provided in the conventional inner body is unnecessary.

As described above, in the present invention, the front and rear size y of the inner body 100 is extended, and the structure of the BB bullet charging groove provided in the inner surface of the inner body 100 is improved longer than before. Looking at the structure of the charging groove (100a: 110a, 120a) with reference to Figure 9 as follows. First, the inner body 100 is composed of a left half 110 and a right half 120 having a symmetrical appearance and are coupled to each other by screws, and inner surfaces of the left half 110 and the right half 120. Each of the charging grooves 110a and 120a is symmetrically formed in the left and right halves 110 and 120 to form a completed BB bullet charging groove 100a when coupled to each other. In addition, the upper end of the left and right half (110, 120) is in communication with the starting portion of the charging groove (100a: 110a, 120a) BB bullet 300 is charged into the charging groove (100a: 110a, 120a) or into the chamber of the gun Long bullet holes (100b: 110b, 120b) are formed to be the entrance and exit when the bullet is sent, the BB bullets 300 is loaded next to the long holes (100b: 110b, 120b). Stopper 130, which serves to press the BB bullets 300 so as not to protrude in the direction is mounted. Here, looking at the structure of the BB bullet charging groove (100a: 110a, 120a), which is one of the main components of the present invention, the charging groove (100a: 110a, 120a) from the bullet holes (100b: 110b, 120b) 100) That is, it consists of a structure formed of two or more rounds in parallel with the vertical axis of the left and right halves (110, 120). That is, the screw fastening holes 110c and 120c are arranged in the center of the left and right halves 110 and 120 in the vertical direction so as to couple them to each other, and have a gentle curve adjacent to the screw fastening holes 110c and 120c. When the imaginary axis drawn in the shape is referred to as the 'up-down center axis (ℓ)', the charging groove (100a) from the bullet holes (100b: 110b, 120b) to be parallel with this up-down center axis (ℓ) as the center axis : 110a, 120a) is formed in the form of two or more rounds. Therefore, the charging groove (100a: 110a, 120a) of the present invention is much longer than the charging groove formed in the conventional inner body, the amount of charge of the BB bullets 300 is also increased by that, for example the present invention When applied as a magazine of the M-series firearms can be charged up to about 200 BB bullets 300.

The BB bullets 300 which are charged in the elongated charging grooves 100a: 110a and 120a should be smoothly fed into the chamber of the gun through the bullet holes 100b: 110b and 120b. In the 120a, a spring 140 is applied to the BB bullet 300 to give a resilient force, and the operation of the spring 140 should be performed smoothly. By the way, in the present invention, the charging groove (100a: 110a, 120a) is longer than the conventional, in order to smoothly supply the BB bullets 300, the resilience of the spring 140 needs to be strengthened more, the bullet It is important for the force to act uniformly on the BB bullets 300 in the charging groove (100a: 110a, 120a). Accordingly, in the spring 140 of the present invention, as shown in FIG. 10, an uneven pitch spring in which a part of the pitch interval is narrower than the pitch interval of the conventional spring is applied. In particular, the material of the spring is a spring of the same material as the back pitch spring that is generally used in the conventional magazine, the pitch interval of the conventional back pitch spring in the present invention is the same as the wide pitch interval, but the pitch interval is narrowed The pitch of the site consists of 70 to 80% of it. For example, the pitch spacing of a conventional back pitch spring is about 4 mm. In the present invention, the pitch of the narrowed pitch spacing is 2.8 to 3.2 mm (that is, about 3 mm), which is 70 to 80% thereof. In addition, according to the experience value obtained by the inventor of the present invention during the development process on the premise of the pitch interval, the innermost end portion of the charging groove (100a: 110a, 120a) (part where the spring guider 150 is seated in FIG. 7) It is preferable to have a structure in which a pitch interval is narrower than that of other portions in a portion that extends from 10 to 60% of the total spring length from the rear end of the spring 140 in contact with the spring 140, and most preferably in the range of 10 to 30%. Table 1 shows the results of the performance test of the magazine according to the pitch change of the spring 140, in each example, the BB bullet 300 is charged in the charging groove (100a), but the same number of bullets, the feed rate In the case of the efficiency of supplying BB shots to the chamber of the gun during the shooting and the ease of the long shot / grenade, the pitch ratio was the best when the optical pitch: narrow pitch = 90 to 70: 10 to 30. In the case of narrow pitch = 60-40: 40-60, it turns out that a favorable result is shown generally.

As described above, in the present invention, the unequal pitch spring 140 having an appropriate pitch ratio is applied, so that the number of rounds of the BB bullet charging groove 100a (110a, 120a) as described above is not limited at all. As the number of rounds (100a: 110a, 120a) increases, the length of the BB bullets 300 may be smoothly supplied even if the length increases.

On the other hand, the spring 140 is provided with a spring insertion hole 120d leading to the charging groove (100a: 110a, 120a) to be mounted in the charging groove (100a: 110a, 120a), the spring insertion hole (120d) is an inner It should just be formed on either of the left and right halves (110, 120) of the body 100, in the present embodiment is illustrated to be formed on the right half (120). When holding the spring 140 by hand through the spring insertion hole (120d) formed as described above, the spring 140 is mounted in the charging groove (100a: 110a, 120a), the spring 140 is the charging groove (100a: 110a, 120a) Spring guider 150 may be provided as a means for maintaining the state mounted stably in the). This spring guider 150, as shown in Figure 11, is fitted to the rear end of the spring 140 when the spring 140 is inserted into the charging groove (100a: 110a, 120a) from the spring insertion hole (120d) ( 140 is mounted in the charging groove (100a: 110a, 120a), when the spring 140 is completely mounted in the charging groove (100a: 110a, 120a) the innermost end of the charging groove (100a: 110a, 120a) It is settled.

Next, when it is necessary to remove the spring 140 and the spring guider 150 from the charging grooves 100a (110a, 120a) for the maintenance of the magazine (especially the inner body), the left and the left of the inner body 100 In order to be able to remove easily without disassembling the screw which couples the right half part 110 and 120, the removal hole 110d is formed in the left half part 110 of the inner body 100, ie, opposite the spring insertion hole 120d. (See FIGS. 8 and 11). That is, the removal hole 110d is formed to face each other with the spring insertion hole 120d, and the spring guider 150 springs by inserting a peak-like tool such as an awl into the removal hole 110d. It is pushed out through the insertion hole (120d), and the spring 140 is also pulled out of the spring insertion hole (120d) by continuing to pull the spring guider 150 pushed out. In particular, in order to allow the spring guider 150 to be pushed out of the spring inserting hole 120d more easily, the spring inserting hole (in the innermost end of the charging groove 120a of the right half 120 on which the spring guider 150 is seated) A seating protrusion 120e is formed to have a slope 120ea toward 120d, and is also inclined at the rear end of the spring guider 150 in contact with the slope 120ea of the seating protrusion 120e. 150a can be formed. Accordingly, as described above, when the spring guider 150 is mounted at the innermost end of the charging groove 100a (110a, 120a), the rear end inclined surface 150a of the spring guider 150 is the inclined surface of the seating protrusion 120e. While being seated in contact with the 120ea, the spring guider 150 slides on the inclined surface 120ea of the seating protrusion 120e when the spring guider 150 is removed using the tip type tool. Are stripped out.

In addition to the above configuration, the structure of the spring guider 150 can be improved as follows. First, the insertion portion 150b of the spring guider 150 fitted to the rear end of the spring 140 is formed long as shown in FIGS. 10 and 11, the length of which is the spring 140 when the spring 140 is compressed. It is enough that it does not protrude out of the spring insertion hole 120d. That is, since the spring insertion hole 120d is completely open, the portion near the rear end of the spring 140 into which the spring guider 150 is inserted is protruded out of the spring insertion hole 120d by the compression force during the strong compression of the spring 140. There is a concern, as the insertion portion 150b of the spring guider 150 supports the spring 140 along the compression direction as long as possible, so that the spring 140 does not protrude out of the spring insertion hole 120d. Furthermore, the guide portion 150b of the spring guider 150 guides the direction in which the spring 150 is compressed or extended at the rear end of the spring 140, so that the spring 140 is not twisted when the spring 140 is compressed or extended, and the charging groove ( 100a: 110a, 120a) to be smoothly compressed / stretched in accordance with the form, which has the effect of preventing the supply failure of the BB bullets 300 in advance. In addition, the insertion portion 150b of the spring guider 150 has rounded corners thereof so that the spring 140 is not caught by the edge of the insertion portion 150b when the spring 140 is compressed (FIG. 10). "R" display section).

As another additional configuration of the present invention, as shown in Figs. 7 and 10 may be provided with a pusher 160 is fitted to the front end of the spring 140, the pusher 160 is a charging groove (100a: 110a, 120a) While acting in contact with the BB bullets 300 therein serves to push the BB bullets 300 toward the long holes 100b by the spring force of the spring 140. Of course, even without such a pusher 160, the spring 140 may be in direct contact with the BB bullets 300, but the pusher 160 needs to be provided to smoothly feed the BB bullets and prevent damage to the bullet section. . By the way, compared to the conventional pusher, the pusher 160 of the present invention is characterized in that the pushing portion 160a in contact with the BB bullet is formed along the stacked shape of the BB bullet 300 (see FIG. 10). That is, the BB bullets 300 stacked in the charging grooves 100a (110a, 120a) are stacked in a substantially zigzag structure as shown in FIGS. 7 and 12, and the BB bullets 300 stacked in such a structure are stacked. ) The pushing portion 160a of the pusher 160 is made to coincide with the shape of the two placed up and down. Accordingly, when the elastic force of the spring 140 acts in the charging groove 100a, the pusher 160 of the present invention is equally pressured with the BB bullets 300 unlike the conventional pusher. Since the contact is received, the pusher 160 is not inclined to one side in the charging groove (100a), it is possible to smoothly supply the BB bullets (300).

The magazine of the present invention disclosed in the above-described embodiment has a maximum number of shots of about 200, but the maximum number of shots can be adjusted by changing the positions of the seating protrusion 120e, the inclined surfaces 120ea and 150a, and the removing hole 110d.

The present invention has been described above based on embodiments, but the technical idea of the present invention is not limited thereto, and modifications or changes can be made within the scope of the claims to those skilled in the art. It is apparent that such changes and modifications belong to the appended claims.

The present invention configured as described above has the following effects.

First, in the present invention, the length of the BB bullet charging groove is increased, but the amount of BB bullets that can be charged increases, but the spring for pushing up the BB bullets in the charging groove onto the barrel is made of an uneven pitch spring so that the supply of BB bullets is very high. It will work smoothly. Moreover, the pusher in direct contact with the BB bullet is made along the stacking shape of the BB bullet so that the BB bullet can be more smoothly supplied. In addition, the spring guider for supporting the spring supports along the compression / extension direction while preventing the spring from protruding through the spring insertion hole even when the spring is strongly compressed, thereby preventing the charging and feeding of the BB bullet. Therefore, the present invention eliminates the inconvenience of frequently replacing magazines during a survival game (or a strategy simulation game), and also makes the game more interesting by smoothly and smoothly progressing the game without a bad loading or feeding failure of BB bullets during the game. There is an effect that can be enjoyed.

Secondly, in the present invention, since the spring and the spring guider can be easily removed from the inner body by a simple pressing operation using a sharp tool, it is necessary to remove and tighten the screws that couple the inner body when maintenance is required. The maintenance work is very easy and simplified by the disappearance, there is no damage to the screw fastening portion has the effect of improving the durability.
