Abstract

PROBLEM TO BE SOLVED: To provide a game nail which is suitably applicable to both wood plywood game panel and resin game panel with the ensurance of preventing the nail from coming off or rotating even when it is driven shallowly into the panel and also preventing the nail from being bent or causing cracks in the game panel when the nail is driven into the panel. SOLUTION: A multiple helical part 70 including a helix 71 with a high ridge part and a helix 72 with a low ridge part is formed in the driven introduction part of a game nail 7 into a game panel. Thus it is possible to ease the difficulty of an operation to drive the nail 7 when its helical part is normally constituted of only the helix having the ridge part of a uniformly large height, and also prevent the bending of the nail or the cracking of the game panel from occurring. Further, it is possible to suppress the excessive enlargement of a hole and extract the bracing force of the helix 71 having a high ridge part and the frictional force of the helix 72 with a low ridge part with a minimum loss. Consequently, the sufficient retaining strength of the nail can be maintained without securing the driven depth of the nail to the much large extent.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pachinko game machine,
Arranged ball gaming machines, game nails driven into so-called ball game machines such as sparrow ball game machines, and game boards driven with these game nails, not only wooden plywood game boards but also synthetic resin game boards Also involves a new structure that fits.

[0002]

2. Description of the Related Art At present, many game boards are made of flat wooden plywood, and many game nails have a spiral ridge formed at the tip thereof. The spiral ridge serves to prevent the driven nail from slipping out and rotating, and to increase its holding strength. When the height of the ridge portion is high, the protrusion to the outside is large, and the biting of the game board becomes strong. However, at the time of driving with a hammer, the game nail may be bent.
For this reason, as the current game nails for wooden plywood game boards, straight nails or those with a protruding outward edge stopped to a certain limit are used, and the game boards have a thick flat board having a thickness of about 15 to 20 mm. Plywood is used, and the holding depth is given by securing a relatively long driving depth of the game nail.

On the other hand, as proposed in Japanese Patent Application Laid-Open No. Hei 4-354960, a wooden plywood made of wood plywood has advantages such as less warpage of a game board due to moisture absorption and peeling of a cell board and excellent quality stability. In place of this game board, a resin game board made of a synthetic resin molded article such as ABS has attracted attention, and the number of applicable models is gradually increasing. In the case of such a synthetic resin game board, if the height of the ridge portion is high, cracks are likely to occur on the game board side. For this reason, as shown in the above-mentioned publication and as shown in FIG. 8, a cylindrical boss BOS for receiving the tip of the game nail is integrally provided on the back surface of the base of the game board PL, and the driving depth is also ensured to be large. This gives the holding strength.

[0004]

However, as described above, the conventional game nail has a spiral ridge at its tip, but when applied to a wooden plywood game board, the thickness of the board is reduced. At present, it is thick and secure, and there is a problem that the weight of the entire game board increases. Also, when applied to resin game boards,
Operation in combination with the boss BOS is required, and the forming of the game board becomes complicated, and the nailing location is limited to the position of the boss BOS, and it is necessary to raise a new mold every time the nail pattern is changed depending on the model. In addition, there is a problem that the back of the game board has many irregularities, which limits the structure of the back mechanism and the like.

According to the present invention, it is possible to sufficiently prevent the pull-out and rotation at a short driving depth, prevent the bending of the game nail at the time of driving and the crack on the game board side, and to play both the wooden plywood game board and the resin game board. It is an object of the present invention to provide a game nail that conforms to the requirements of the game nail and a game board utilizing the advantages of the game nail.

[0006]

According to a first aspect of the present invention, as shown in FIG. 2, a plurality of types of spiral bodies 71 and 72 having different ridge heights are mixed in a driving insertion portion. The multiple spiral portion 70 is provided. The one shown is the first spiral 7
Although there are two types of the first and second spiral bodies 72, three or more types may be provided.

According to the invention of a second aspect of the present invention, as shown in FIG. 3, a ridge having a low height mainly increases the frictional force of the spiral body 72 having a low ridge to increase the holding strength. The width W2 of the top of 720 is wider than the width W1 of the top of the ridge 710 having a higher height.

According to the third aspect of the present invention, a plurality of spiral bodies are provided for each type, so that one kind of spiral body does not apply an eccentric load to the center and prevent nail falling. Adjacent components of the type of helix were equally spaced. In the example of FIG. 3, between adjacent components of the first spiral 71, that is, between the reference numerals 71a and 71b, and between the reference numerals 71b and 71b.
1a are equally spaced at 180 °, and between adjacent components of the second spiral 72, that is, between symbols 72a and 72b and between symbols 72b and 72a are all equally spaced at 180 °. The points apply. In the illustrated example, each spiral 7
Each of the components 1 and 72 includes two components, but each component may include three or more components.

According to the fourth aspect of the present invention, in order to achieve a good balance of force with respect to the center, a screw of another kind is provided at an intermediate position between adjacent components of a screw of one kind. Was placed. In the example of FIG. 3, the point that the component 72 a or 72 b of the second spiral 72 is disposed at an intermediate position between the adjacent components 71 a and 71 b of the first spiral 71, that is, at a position displaced by 90 °.

According to a fifth aspect of the present invention, as shown in FIG. 1, the gaming nail 7 has a multiple spiral portion 70 in which a plurality of types of spirals having different ridge heights are mixed in a driving insertion portion.
The game nail 7 was driven into the base 1 with a driving depth L1 in the range of 1/4 to 2/5 (0.25 to 0.4) with respect to the total length L1 + L2. The example is 27m in total length
m, the driving depth is 9.2 mm, and 9.2 / 27 = 0.
34.

In the game board according to the sixth aspect of the invention, as a most preferable example, the driving depth relative to the entire length is reduced to about 1/3. The example is 0.34, which is approximately 1/3 = 0.33.

In the game board according to the seventh aspect of the present invention, the base is made of a resin flat plate in order to improve the degree of freedom of nailing and to reduce costs by eliminating the boss.

[0013]

According to the invention of the game nail according to the first aspect,
A multi-spiral portion in which a spiral body having a high ridge and a spiral body having a low height are mixed is provided in a driving insertion portion into a game board. By the way, when the spiral part is composed of only one kind of spiral body with a high ridge, the resistance at the time of driving the game nail is large and it is difficult to drive, and the nail is bent at the time of driving into the wooden plywood game board. Also, there is a possibility that the game board may be cracked when driven into a resin game board. In addition, the hole may be too wide, and the holding power may not be higher than expected. On the other hand, in the case where the spiral portion is composed of only one kind of the spiral having a low height of the ridge portion, it is easy to drive the game nail,
Generally, the holding power tends to be insufficient, and the driving depth must be increased.

However, in this device, since it is a multiple spiral portion in which both are mixed, difficulty in driving can be reduced, and bending of a nail and cracking of a game board can be prevented. Also,
Excessive expansion of the hole can be reduced, and the tension force of the spiral body having a high ridge and the frictional force of the spiral body having a low ridge can be satisfactorily extracted with little loss. For this reason, a sufficient holding strength can be obtained even if the driving depth is not so large, and the play nail can be effectively prevented from coming off or rotating. Therefore, when applied to a wooden plywood game board, the thickness can be reduced by reducing the thickness, and when applied to a resin game board, the boss can be eliminated.

In the game nail according to the second aspect of the present invention, the spiral body having a small height of the ridge is also likely to come into contact with the inner surface of the driving hole into the game board because the width of the top of the ridge is wide. The width of the lower ridge, which is mainly the resistance at the time of driving, is made wider than the width of the top of the higher ridge, so that the resistance at the time of driving does not increase. For this reason, the frictional force can be increased mainly by the spiral body having a low ridge, so that the holding strength can be effectively increased.

In the game nail according to the third aspect of the present invention, since the adjacent components of one kind of spiral body are at equal intervals, there is little possibility that a large eccentric load such as a large torsion or a fall acts on the center. For this reason, straightness is good for a predetermined driving angle, and unexpected falling down can be prevented.

According to the fourth aspect of the present invention, the effect of the eccentric load between the different kinds of spirals having different heights of the ridges can be reduced, and the balance of the force with respect to the center can be kept better as a whole. As a result, the linearity can be more favorably obtained, and the bonding strength can be increased.

According to the fifth aspect of the present invention, the driving depth relative to the total length is 1/4 to 2/5, that is, 0.25 to 0.25.
Gaming nails are driven into the base within the range of 0.4. Since the length of the game nail protruding from the board is determined by the standard from the size of the game ball, according to the driving depth in the right range, the driving depth of the game nail is shallower than the conventional one, and the total length of the game nail Will also be short. Compared to the applicant of the present invention, a resin-made game board with a boss using a conventional nail has a length of 15.5 mm from the surface of the game board to the back of the boss, and the actual nail penetration depth is 15.2 mm. The projection length of the board is 16.8 mm (17.8 mm including the head) according to the standard, so the total length is 33 mm.
The driving depth relative to the entire length is 15.2 / 33 = 0.46. Therefore, the driving depth is 15.2-9.2 = 6 m.
m, the overall length was also reduced by 33-27 = 6 mm. For this reason,
The board on the game board side can be made thinner, and the weight of the game nail itself can be reduced, thus promoting the overall weight reduction.

In the game board according to the sixth aspect of the present invention, since the driving depth relative to the entire length is reduced to approximately 1/3, it is possible to secure the holding strength of the game nail and to reduce the thickness of the base by shortening the driving depth. Can also be pushed well.

In the invention of the game board according to the seventh aspect, since a resin flat plate is used for the base, the formation of the game board is simple, there is no protrusion of the boss on the back of the base, and the degree of freedom of nailing is improved. It is also possible to arrange a display device on the back of the base, attach a cell image, directly attach a winning ball passage, and improve the degree of freedom of the configuration of the back of the game board.
