Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a structure for attaching parts in a gaming machine such as a pachinko machine, such as a winning tool, a windmill, and decorative parts, to be attached to a plywood gaming board in a gaming machine such as a pachinko machine.

<Prior Art> As is well known, on the surface of the game board of a game machine such as a pachinko machine, there are attached prizes such as chips, windmills, display devices with lamps, decorative parts such as plaques, and many other parts. ing. Therefore, the conventional component has a mounting board extending in the shape of a collar, and the mounting board is provided with a plurality of mounting holes.
On the other hand, a game board made of laminated plywood or the like has insertion holes into which the above-mentioned parts can be inserted, and small holes are provided around the insertion holes in correspondence with the above-mentioned mounting holes.
Then, insert the component into the insertion hole, bring the back side of the mounting board into close contact with the surface of the game board, align the mounting hole with the small hole, fix the screws, nails, etc. that pass through the mounting hole into the small hole, and then attach the component to the small hole. is installed.

Furthermore, Japanese Utility Model Publication No. 51-144283 discloses a decorative tool for a pachinko machine in which a window hole is bored in a decorative tool made of synthetic resin, and a decorative plate having a hook portion is removably fitted into the window hole. Proposed.

<Problem to be solved by the invention> However, in the conventional parts mounting structure, screws etc. are fixed while aligning the mounting holes of the mounting board with the small holes provided in the game board. Not only is it extremely time-consuming and labor-intensive to install, but the mounting position is also likely to shift, and if it is installed in a shifted position, it is necessary to remove the screws and try again. Furthermore, when the process of fixing screws is mechanized, mechanical equipment having a large number of assembly mechanisms proportional to the number of mounting holes is required, which increases costs.

It is also possible to provide a hook part on the part and have this hook part lock onto the periphery of the insertion hole made in the game board, but simply providing the hook part on the part to be installed will not allow the other party's insertion hole to lock. However, since it is formed by router processing or the like on plywood, there are burrs and the like around the insertion hole, which prevents the game board and the mounting board from coming into close contact with each other, making it difficult to apply effectively.

<Means for Solving the Problems> The present invention was proposed in view of the above, and is a mounting structure for parts to be attached to a plywood game board of a game machine. A groove corresponding to the periphery of the inserted insertion hole is formed, and a pair of elastic mounting arms with a width corresponding to the inner diameter of the insertion hole are provided opposite each other, and the width is approximately parallel to the axial direction of the mounting arms. A pair of guide parts are provided in the orthogonal direction at intervals corresponding to the inner diameter of the insertion hole, and a locking part facing outward is provided at the tip of each of the above-mentioned mounting arms. The mounting arm is inserted into the mounting hole so that the locking portion is locked to the peripheral edge of the insertion hole, and the guide portion is brought into contact with the inner surface of the insertion hole.

<Function> The opposing elastic mounting arms can be elastically deformed inward within the gap and inserted into the insertion holes made in the game board, and the locking portion provided at the tip of the mounting arms can be inserted. The parts can be attached to the game board by being locked to the peripheral edge of the mounting hole. Further, the guide portion does not come into contact with the inner wall of the insertion hole and shift, and the mounting board can be brought into close contact with the game board even if burrs are formed around the insertion hole.

<Embodiment> The present invention will now be described with reference to an embodiment shown in the drawings. FIG. 1 is a perspective view of a variable prize-winning device 1, which is a part having an attachment structure according to the present invention, seen from the rear.

The variable prize winning tool 1 has a movable wing piece 4 that can be rotated by a shaft 3 on the front surface of a mounting board 2, and a state in which it is easy to win a prize and a state in which it is difficult to win by rotating the movable wing piece 4 when a game ball wins a prize. The mechanism part 5 is provided with an operating lever 6 that tilts under the load of the ball and a rear frame 7 that guides the ball so as to extend to the back surface of the mounting board 2. There is. Further, a pair of mounting arms 8 facing each other are provided on the sides of the mechanism section 5 and extend rearward, and a gap 11 is provided between the inner surface 9 on the opposing side of the mounting arms 8 and the outer surface 10 of the mechanism section 5. is formed to allow elastic deformation of the mounting arm 8 inward by the opposing interval.
Further, an upper guide part 12 and a lower guide part 13 having chamfered tips are provided at the upper and lower ends of the mechanism part 5.
will be established.

Note that the width of the mounting arms 8, 8 is determined by the width of the game board a, which will be described later.
It almost matches the inner diameter of the corresponding part of the insertion hole b. In addition, the upper guide part 12 and the lower guide part 1
The width of 3 approximately coincides with the inner width of the corresponding portion of the insertion hole b of the game board a, which will be described later. Furthermore, instead of providing both guide parts 12 and 13, mounting arms 8 may be provided at the upper and lower ends, or mounting arms 8 may be provided at the upper and lower ends and guide parts 12 and 13 at the left and right ends. good. In short, the axial direction of the arm 8 and the axial direction of the guide parts 12 and 13 may be arranged so as to be substantially perpendicular to each other to function as a position regulating means, and the variable prize winning tool 1 may be placed within the insertion hole b. It should be fine as long as it doesn't wobble.

Then, the mounting board 2, the mounting arm 8, as described above,
The rear frame 7 and both guide parts 12 and 13 can be integrally molded from synthetic resin.

An outward locking portion 14 is provided at the tip of the mounting arm 8. According to the embodiment shown in FIGS. 1 to 3, the locking portion 14 has a triangular claw shape, and includes an inclined portion 15 that slopes outward from the tip of the mounting arm 8, and a slope portion 15 that slopes outward from the tip of the mounting arm 8. It has a jaw part 16 communicating with the outer surface of the game board at a right angle or an acute angle, and the distance between the jaw part 16 and the back surface of the mounting board 2 is made to almost match the thickness of the game board a.

On the other hand, at a predetermined position on the game board a, there is a variable prize winning tool 1.
An insertion hole b into which the mechanical part 5 can be inserted is opened. The insertion hole b has a width equal to the distance between the outer surfaces of both mounting arms 8, and a height equal to the distance between the outer end surfaces of the guide portions 12 and 13.

In addition, the game board a uses laminated plywood with little warpage, expansion, or contraction, and the cell board c with a picture or pattern printed on the surface of the plywood is pasted, so when opening the insertion hole b. Chips and the like may enter between the cell board and the plywood, causing burrs, and the peripheral edge of the insertion hole b on the game board surface side may bulge. If the variable winning tool 1 is inserted into the insertion hole b with a raised peripheral edge, the back surface of the mounting board 2 and the surface of the game board a will not come into close contact, so the variable winning tool 1 cannot be installed accurately. Can not. Therefore, in the present invention, a groove 17 is formed on the back surface of the mounting board 2 so as to correspond to the peripheral edge of the insertion hole b. This groove 17 accommodates any burrs that may bulge on the peripheral edge of the insertion hole b, allowing the back surface of the mounting board 2 to be brought into close contact with the surface of the game board a, thereby ensuring that the variable prize winning tool 1 is securely attached to the game board a. Can be installed on.

To attach the variable prize winning tool 1, which is a component having the mounting structure according to the present invention, to the insertion hole b of the game board a,
The mounting arm 8 may be pushed into the insertion hole b from the front of the game board a. To explain in detail, the variable prize winning tool 1 is inserted with the locking part 14 of the mounting arm 8 facing the insertion hole b from the front.
When pressed backward, the inclined portion 15 of the locking portion 14 is pushed against the wall surface of the insertion hole b, the mounting arm 8 is elastically deformed into the space 11, and the locking portion 14 passes through the insertion hole b. When the locking part 14 passes through the insertion hole b and protrudes to the back side of the game board a, the inward pressure on the locking part 14 is removed, so the mounting arm 8 returns to its original position and the jaw part 16 is locked on the back side of game board a, and variable prize winning device 1
The game board a is sandwiched between the jaw part 16 and the mounting board 2, and the variable winning prize tool 1 cannot be pulled out forward. Also,
In the vertical direction, the outer end surfaces of the guide parts 12 and 13 abut against the upper and lower inner walls of the insertion hole b, so that they can be securely fixed in the insertion hole b without moving up and down.

The shape of the locking portion 14 of the mounting arm 8 in the present invention is not limited to the above embodiment. for example,
As shown in FIG. 4A, the jaw 16 is formed in a triangular shape with a slope forming a pure angle with respect to the outer surface of the mounting arm 8, or as shown in FIG. 4B, the jaw 16 serrated teeth 18 may be provided. According to both of the above embodiments, even if the adhesive layer of the game board a made of laminated plywood is uneven or the thickness changes due to changes in humidity, the mounting arm 8 has elasticity, so that the jaw part 16 is inclined. In addition to responding to variations in the thickness of the game board a, the jaw portion 16 comes into pressure contact with the corner of the insertion hole b, so that the locking portion 14 can be locked in the insertion hole b. Further, in the embodiment in which saw-shaped teeth 18 are provided, the locking of the locking portion 14 becomes even more reliable. In FIG. 4C, the locking portion 14 is formed into a curved shape. With such a locking portion 14, it is possible to cope with variations in the thickness of the game board, and it can be smoothly inserted into the insertion hole b. become. Further, in FIG. 4D, the locking portion 14 is formed in a curled shape. According to this locking part 14, since the tip part 14' of the curl has elastic force in the length direction of the mounting arm 8, it can be handled reliably even if the thickness of the game board a changes to some extent. Can be installed with arm 8
Combined with its elasticity, more reliable attachment is possible.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above embodiments.
As long as the content stated in the claims for utility model registration is not changed, it can be implemented in any way.

Further, the parts of the present invention are not limited to variable winning prizes, but can be applied to display devices such as windmills, decorative plates, lamps, and other parts in gaming machines.

<Effects of the invention> According to the invention, the mounting arm is elastically deformed to pass through the insertion hole made in the plywood game board, and the locking part at the tip is locked around the insertion hole to attach the component. Not only can it be installed directly on the game board, but also
Even if there are burrs around the insertion hole, the mounting board can be tightly attached to the game board, and the guide part and the mounting arm themselves function as position regulating means, so they will not shift within the insertion hole. . Moreover, the fixing work is extremely simple and can be installed in a short time.
Furthermore, according to the present invention, there is no need to provide mounting holes on the mounting board or to form small holes on the game board.
