2. Description of the Related Art Conventionally, as an outer casing for a game machine of this type, for example, in a slot machine, a woodworking product using a plywood material is used as the outer casing. However,
It has been pointed out that there is a demand for protection of forest resources, and that a conventional outer casing, which is a woodworking product, requires a large space for storage and transportation, resulting in high distribution costs. To address these issues, Japanese Patent Laid-Open No. 2000-2000
-70540 and Japanese Patent Laid-Open No. 2000-70541 are proposed.

In the former case, "a plurality of resin-made face plates which are substantially box-shaped outer casings in which a front surface for incorporating a game machine is opened and which are arranged so as to surround the front surface for incorporating a game machine, It has a back plate facing the front and a reinforcing frame interposed between a plurality of face plates for reinforcement, and the plurality of face plates have a fitting structure that fits with each other. An assembled outer casing for a game machine, which is characterized in that it is detachably coupled, has been proposed.

In the latter, "a plurality of resin-made face plates which are substantially box-shaped outer casings in which a front surface for incorporating a game machine is opened and which are arranged so as to surround the front surface for incorporating a game machine, A back plate facing the front, and at least a part of each face plate has a recess on the inner surface, and the plurality of face plates are pivotally supported so as to be foldable to the left and right and up and down of the back plate, and Has a fitting structure that fits with each other, and at the time of assembly, a plurality of face plates and a back plate are disassembleably coupled using a connector, and an assembly outer casing for a game machine is proposed. ing.

These proposals have the effect that a stable supply can be achieved by using a recyclable resin material without being influenced by wood resources, and the cost required for distribution can be reduced. Is playing.

[0006]

Recently, however, the number of assembled parts has been reduced and
Further cost reduction is required by reducing the number of assembly steps. Also, in order to reduce the number of assembly steps for products, product manufacturers are required to modularize parts manufacturers.

The above-mentioned Japanese Patent Laid-Open No. 2000-70540.
According to the techniques disclosed in Japanese Patent Laid-Open No. 2000-70541 and Japanese Patent Laid-Open No. 2000-70541, the outer casing is used by a pachislot maker, which is a product maker, for assembling and assembling related parts. However, only the outer casing is used. However, there is a problem that the number of parts is large and the number of assembling steps is too large, which causes a cost increase.

Further, in the technique disclosed in the above-mentioned publication, by changing from woodworking products to resin products, conservation of natural environment and stable supply by cutting down forests are solved.
Further, although it is a recyclable material, it has a drawback that it cannot sufficiently cope with resource saving and weight saving by further efficient use of resin material. That is, the outer casing disclosed in the above publication requires the use of many materials in order to achieve sufficient product strength.

The present invention has been made by paying attention to the problems of the prior art as described above. The problem is that a resin material is used, and the product strength is improved when the outer frame is stored and transported. By setting the weight enough to withstand a load (for example, about 300 kg), making it lighter and making it easier to dismantle, it is possible to protect wood resources, conserve resources, and even recycle them, making them environmentally friendly. It is to provide a gentle outer casing for a game machine.

11), at least one of which is provided, and the fitting piece (201) and the fitted groove (21) are provided along both side edges and a rear edge of the upper surface plate (14) matching the respective upper edges.
By providing at least one of the above 1), the upper and lower edges of the left and right side plates (12, 13) and the back plate (11), and both side edges of the upper plate (14) matching the respective upper edges. By fitting the fitting piece (201) and the fitted groove (211), which are assembled so as to face each other, and the rear end edge, it is possible to easily and firmly join them.

As a result, the left and right side plates (12, 13)
In addition to ensuring the strength and rigidity of the back plate (11) itself, a plurality of face plates (11 to 1) are formed by the fitting structure of the fitting piece (201) and the fitted groove (211).
5) In particular, the assembling strength of the left and right side plates (12, 13), the back plate (11), and the top plate (14) after they are assembled together is also sufficient to withstand a considerable load and rigidity. Can be secured.

The fitting piece (201) and the fitted groove (2)
11), but along each upper edge of the left and right side plates (12, 13) and the back plate (11), or the top plate (1
It is also possible to provide either one of the fitting piece (201) and the fitted groove (211) along both side edges and the rear end edge of 4). Two
01) and the fitted grooves (211) are alternately arranged, they are combined so as to face each other in a knuckle shape, and the fitting structure can be further strengthened.

Here, a flange portion (1) extending downward with a predetermined width along both side edges and a rear edge of the upper surface plate (14).
4a) are integrally formed, and the fitting pieces (201) and the fitted grooves (211) are arranged alternately along the flange portion (14a), thereby improving the fitting structure. The rigidity of the peripheral edge of the face plate (14) can be increased.

As described above, the fitting structure of the fitting piece (201) and the fitted groove (211) has the upper ends of the left and right side plates (12, 13) and the back plate (11). It is not limited to the edges and both side edges and rear edges of the upper surface plate that match the upper end edges, but the left and right side surface plates (1
2, 13) and each lower edge of the back plate (11), and both side edges and rear edge of the bottom plate (15) matching the respective lower edge, the same can be applied to thereby, It is possible to further improve the assembling strength of the entire casing.

Further, a locking portion (36) for holding the shelf plate (16) at a desired position is provided inside each of the left and right side plates (12, 13), and both end edges of the shelf plate (16) are provided. By providing a locked portion (16a) which is integrally fitted to the locking portion (36) on the shelf plate (16), the shelf plate (16) can be firmly attached so as not to be displaced, and the shelf plate (16) ) Forms a partition wall that divides the substantially box-shaped inner space into upper and lower spaces, so that the torsional strength of the entire game machine outer casing (10) can be significantly increased.

In addition, when a locking portion (36) for holding the shelf plate (16) at a desired position is provided inside each of the left and right side plates (12, 13), the locking portion (36) is provided. ), The mold cavities of the constant area part (E) including the part corresponding to the locking part (36) are replaced when the left and right side plates (12, 13) are molded. If possible molds (100) are used, it is possible to meet different specifications for each slot machine maker.

Similarly, when the bottom plate (15) is provided with a locking portion (39) for holding the related parts at a desired position, the position of the locking portion (39) can be changed. Therefore, when molding the bottom plate (15), it is preferable to use a mold (100) capable of replacing the mold cavity of the constant area part (F) including the part corresponding to the locking part (39). As a result, it is possible to easily manufacture a plurality of types of bottom plates (15) having different locking portions (39) at the injection molding stage, and to prepare a special nest at the stage of assembling related parts. There is no need.

Of the plurality of face plates (11-15),
At least the left and right side plates (12, 13) are connected to the back plate (1
When the left and right sides of 1) are foldably supported inside the back plate (11), they can be folded and assembled easily and quickly, and because they are folded and overlapped, there is little space for storage and transportation. Complete. Moreover, the number of parts and the number of assembling steps are reduced, and in particular, the number of assembling steps on site in the product manufacturer can be minimized, and the cost can be significantly reduced.

By the way, when the game machine outer casing (10) is used in a general slot machine, the total weight of the game machine (1) incorporating the related parts is about 50 kg per unit. When storing or transporting 1), for example, if 6 units are piled up and down via a pallet, the total load for a maximum of 6 (300
kg) may be applied to one game machine (1).

Therefore, the left and right side plates (12, 13) and the back plate (1) which form the main part of the outer casing (10) for the game machine.
1) is composed of a resin base body (20) including a pair of wall surfaces (21, 22) facing each other and a rib (23) connecting the wall surfaces (21, 22) to each other. The ribs (23) in 20) are arranged in a predetermined manner that can withstand the total load from above.

By disposing the ribs (23) in the resin base body (20) as described above, the hollow ratio of the resin base body (20) is about 30% while ensuring sufficient strength and rigidity as an outer casing. By setting to 80%, the weight can be sufficiently reduced and the disassembly becomes easy. Of course, the use of the resin material protects the wood resources and can meet the demand for resource saving and recycling.

In order to mold the resin base body (20), the movable core (11) which can be retracted into and out of the mold cavity.
It is advisable to adopt a unique injection molding using a mold (100) that has 0) and can expand and contract the cavity volume by moving the cavity surface. That is, first, the molten resin is injected into the cavity, and when the injection is completed, the movable core (11
High pressure gas is injected with 0) still protruding. The gas is injected into the low viscosity portion inside the molded product to form a hollow portion (24).

Subsequently, when the movable core (110) is withdrawn, the resin is pulled to the portion, and the ribs (23).
Nuclei are formed, and due to the expansion of the cavity volume, both the wall surfaces (21, 22) and the ribs (23) constituting the resin base body (20) are stretched together to increase the hollow ratio. A resin base body (20) having ribs (23) arranged at the positions is formed. Then, after the gas is released and cooled, the resin base body (20) may be taken out from the mold (100).

By adopting such injection molding, it becomes possible to accurately form the rib (23) whose placement is predetermined at a desired position inside the resin base body (20). ), Sufficient strength can be secured, and a high hollow ratio for weight reduction can be obtained. Further, it is possible to effectively prevent warpage and sink marks caused by a general synthetic resin molding method, and it is also possible to mold more quickly.

If approximately 75% or more of the plurality of face plates (11 to 15) forming the outer casing (10) for a game machine is made up of the resin base body (20), the weight is further reduced than in conventional products. Can be achieved. Also,
Depending on the degree of load, the upper plate (14), the left and right side plates (12, 13), and the rear plate (11) are
The hollow ratios of the respective resin base bodies (20) constituting each may be different from each other. For example, it is conceivable that the back plate (11) to which a load is applied in the vertical direction in particular has a lower hollow ratio than the others to increase the strength.

If the rib (23) is joined to both wall bodies (21, 22) of the resin base body (20) as a support portion (23a) which is thickened and reinforced. , The rib (2
3) Since the whole is further reinforced, the strength and rigidity of the resin base body (20) itself can be surely improved. Here, the support portion (23a) can be easily formed, for example, by adding a rounded radius to the corner of the joint between the both wall surfaces (21, 22) and the end of the rib (23).

Further, regarding the arrangement of the ribs (23) in the resin base body (20) in a predetermined manner, specifically, for example, a manner in which a plurality of ribs extend radially from one or a plurality of locations on both wall bodies (21, 22). You may In addition, a plurality of wall surface bodies (21, 22) may extend in parallel in the vertical direction or the horizontal direction, or may be arranged in a honeycomb shape between the wall surface bodies (21, 22), or both wall surface bodies (21 , 2
2) A plurality of columns (231) arranged at arbitrary positions between
And rib pieces (232) extending in at least one direction from each of the columns (231).

Further, the front door (2) is formed to form a front surface, and one of the left and right side plates (12, 13) is connected to the front end edge of each of the top plate (14) and the bottom plate (15) connected to the upper and lower sides thereof. It may be mounted through a metal plate (40) that integrally connects the front side of the side edge. Here, the sheet metal (40) is the front door (2).
It is sufficient to use the side pieces of the hinges that can be opened and closed as it is, and the sheet metal (40) can further improve the assembly strength without increasing the number of extra parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments representing the present invention will be described below with reference to the drawings. 1 to 27 show a first embodiment of the present invention. The outer casing 10 for a game machine according to the present embodiment has a front face opened for incorporating the game machine, and includes a plurality of resin face plates 11 to 15 arranged on the left, right, top, and bottom so as to surround the front face. It is of a substantially box type. Hereinafter, as a game machine, FIG.
The case of configuring the slot machine 1 shown in FIG. 4 will be described as an example.

As shown in FIGS. 1 and 2, the outer casing 10 for a game machine is a hexahedron, and has a plurality of face plates 11 to 15 surrounding the opened front face, and a back face plate 11 opposed to the front face.
It has a right side surface plate 12, a left side surface plate 13, an upper surface plate 14, and a bottom surface plate 15, and a basic framework is composed of these five surface plates 11 to 15.

Each of the face plates 11 to 15 is formed of a synthetic resin material having a rigidity sufficient to withstand a load load that is normally expected when the slot machine 1 is assembled. Of the face plates 11 to 15, the left and right side plates 12, 13 and the back plate 11, in particular, are a resin base body made of a pair of wall surfaces 21, 22 facing each other and ribs 23 connecting the wall surfaces 21, 22. 20.

The resin base 20 is formed from a resin material in a panel shape. More specifically, as shown in the cross section in FIG. 5, the pair of wall surface bodies 21, 22 are thin plate-shaped, and both wall surface bodies 21 and 22 are arranged so as to face each other at a predetermined interval. , 22 are integrally connected via a rib 23.

The end faces around the resin base body 20 are also covered by thin plate walls of the same degree as the front and back wall faces 21 and 22, and the gap between the inner face of both wall faces 21 and 22 and the outer face of the rib 23 is hollow. It becomes part 24. Here, the hollow portion 24 with respect to the entire volume (that is, volume) that surrounds the outer surface of the resin base body 20.
The ratio occupied by is defined as the hollow ratio. The hollow ratio is calculated by the following formula. Hollow ratio = (volume after molding-initial volume) / volume after molding x 10
0 {initial volume = volume of both wall surfaces 21, 22 + volume of rib 23}

The post-molding volume means the molded resin substrate 2
0 is the entire volume (that is, volume) surrounding the outer surface, and in FIG. 6, the thickness H of the resin base 20 is added to the surface area of one wall 21 of the resin base 20 (or the other wall 22 may be used).
It is a value obtained by integrating 0. Further, the volume of both wall surface bodies 21, 22 is the sum of the volume of one wall surface body 21 and the volume of the other wall surface body 22.

The volume of one wall body 21 is obtained by integrating the surface area with the thickness H1, and the volume of the other wall body 22 is obtained by integrating the surface area with the thickness H2. When there are a plurality of ribs 23, the volume of the ribs 23 is calculated by adding the thickness H3 to the surface area on one side of each rib. In addition,
In the present embodiment, the volume of the end face portion around the resin base body 20 is not considered. In addition, the hollow portion 24 does not mean only a completely closed space, but may include a portion of the hollow portion 24 that is slightly open to the outer surface of the resin base 20.

The ribs 23 of the resin base 20 are arranged in a predetermined mode capable of withstanding a load from above the resin base 20, and the hollow ratio of the resin base 20 is specifically about 30. It is set to -80%. As shown in FIG. 4, the resin base body 20 has a pair of wall bodies 21, 22 arranged to face each other at a predetermined interval, and a rib 23 having a joint portion heated or solvent-bonded at a predetermined position therebetween.

The placement position of is slightly different depending on each slot machine manufacturer. In order to change the position of the locking portion 39, when molding the resin base body 200e forming the bottom plate 15, for example, a mold cavity of a certain area including a portion corresponding to the locking portion 39 ( It is advisable to use a mold capable of exchanging (nesting) (portion F shown in FIG. 23).

Next, the operation will be described. Before assembling the outer casing 10 for a game machine described above, first, the resin base bodies 20 and 200 forming the face plates 11 to 15 are molded. Among them, as a concrete molding method of the resin base bodies 20a to 20c constituting the left and right side plates 12 and 13 and the back plate 11, as shown in FIG. The ribs 23 are arranged so as to face each other, and the ribs 23 are arranged at predetermined positions between them, and the joint portion of the ribs 23 is heated or solvent-bonded, and pressure is applied from the outside of both the wall bodies 21 and 22. It is advisable to mold them by bonding them to each other. As a resin material,
Specifically, for example, high-impact polystyrene is suitable.

Of course, it may be molded by various injection molding methods represented by blow molding, hollow injection molding, high hollow injection molding and the like. Here, the blow molding method is that a thermoplastic resin material is extruded or injection-molded to be preformed into a tube shape (this preform is called a parison), which is sandwiched between molds to blow gas inside. This is a molding method in which it is inflated and solidified by cooling. In addition, the hollow injection molding method is also called gas injection molding or gas assist injection molding, and in the injection molding process, a gas body is injected into the molten resin in the mold to obtain a molded product having a hollow portion. It is a molding method.

The high hollow injection molding method is a mold 1 that has a movable core 110 that can be retracted into and out of the mold cavity, and that can expand and contract the cavity volume by moving the cavity surface.
It is an excellent injection molding method in which a large hollow portion 24 can be formed by moving the movable core 110 by using No. 00, and the rib 23 partitioning the hollow portion 24 can be molded at an accurate position and size.

To describe the high hollow injection molding method in more detail, in FIG. 27, first, as shown in FIG. 27A, the mold 1 in which a thin portion is locally provided by the movable core 110 is provided.
A molten resin such as high-impact polystyrene is injected into the cavity of 00. When the injection is completed, as shown in (b), high-pressure gas is injected with the movable core 110 still protruding. Such a gas is injected into a low-viscosity portion inside the molded product to form a hollow portion 24 and a resin wall serving as the rib 23.

Then, as shown in (c), when the movable core 110 is withdrawn, the resin is pulled to the relevant portion, and the core of the rib 23 is formed. At the same time, due to the expansion of the cavity volume, both the wall surfaces 21 and 22 and the ribs 23 forming the resin base bodies 20a to 20c are extended together to increase the hollow rate, and the ribs 23 are arranged at desired positions. The resin base bodies 20a to 20c are formed. Then, after the gas is released and cooled, the resin 100 is removed from the mold 100.
Just take out 0.

By adopting such an injection molding, it becomes possible to accurately form the ribs 23 whose positions are determined in advance at desired positions inside the resin base bodies 20a to 20c, and the ribs 23 are sufficient. It is possible to secure the strength and to obtain a high hollow ratio for weight reduction. Further, it is possible to effectively prevent warpage and sink marks caused by a general synthetic resin molding method, and it is also possible to mold more quickly.

Resin substrates 20a to 20a in this embodiment
c is a pair of wall surface members 2 facing each other as shown in FIG. 5 by using any of the above-mentioned various molding methods.
Ribs 2 for connecting the wall surfaces 1 and 22 and the wall surfaces 21 and 22.
3 is formed into a cross-sectional shape. Both wall surfaces 21, 22
On the other hand, the portion to which the rib 23 is joined is rounded to have a thick wall, and is formed as a support portion 23a for reinforcing the rib 23.

The support portion 23a is formed so as to be crushed by pressure in the molding method shown in FIG. 4, and is naturally formed by various injection molding methods due to its molding characteristics. Due to the presence of the supporting portion 23a of the rib 23, the connecting area of the rib 23 with respect to the inner surface of each of the wall surfaces 21 and 22 is expanded, so that the resin base bodies 20a to 20c can be thinned while ensuring their strength. Becomes

When the outer casing 10 for a game machine is used for a general slot machine 1, the total weight of the game machine 1 in which the related parts are incorporated is about 50 kg. When transporting, for example, when stacking in units of 6 through a pallet, the total load for a maximum of 6 300kg due to variations in mounting condition and height.
May affect one slot machine 1.

The ribs 23 of the resin base bodies 20a to 20c are arranged in a predetermined mode capable of withstanding the load from above on the resin base body 20 to such an extent that it can withstand such a total load sufficiently. As described above, the radial arrangement of the ribs 23 on the back plate 11 shown in FIG.
Ribs 23 on the left side plate 13 (right side plate 12) shown in FIG.
By arranging the upper and lower parts radially, sufficient strength and rigidity as an outer casing can be secured.

Moreover, the hollow ratio of the resin base body 20 is about 30.
By setting it to ˜80%, it is possible to reduce the weight sufficiently, and it is no longer necessary.
It will also be easier to dismantle. Of course, by using resin material,
This will protect the wood resources, and can meet the demand for resource saving and recycling.

Here, the hollow ratio is a value calculated by (volume after molding-initial volume) / volume after molding × 100, as described above. Particularly when the resin substrate 20 is molded by the high hollow injection molding method, it can be defined by the following equation. Hollow ratio = (volume of mold cavity after core back-injection weight / density) / volume of mold cavity after core back x
100

The specific hollow ratio is as described above, but in the back plate 11 shown in FIG. 7, the plate thickness is 9 mm and the hollow ratio is about 50%, and in the left side plate 13 (right side plate 12) shown in FIG. The plate thickness is 15 mm and the hollow ratio is about 60%. Any of the face plates 11 to 13 is considerably lighter than the weight of a conventional wooden face plate having substantially the same volume.

About 50% and about 60% of the hollow ratio are
The above-mentioned approximately 30 to 80% which is the optimum range of the hollow ratio.
It is the one selected near the middle of. Here, the lower limit value of “30” indicates that the hollow ratio is 30% according to the investigation by the inventors.
When it is less than, it becomes heavier than a wooden face plate having substantially the same volume, and has a significance as a critical point for realizing weight reduction. On the other hand, the upper limit value of “80” is also the same as the investigation by the inventors.
Since the volume occupied by the resin is too large to withstand the total load of 300 kg, it has a significance as a critical point for maintaining the physical properties of the resin base 20 when a predetermined load is applied.

For example, as the back plate 11 alone, its hollow
The relationship between the ratio and the strength against the load is that
The data will be as follows depending on the test. In addition, used for the experiment
The back plate 11 shown in FIG. 7 is used for resin material.
I Impact polystyrene is used. When the hollow ratio is 52%, the maximum stress is 2.8 N / mm^Two When the hollow ratio is 65%, the maximum stress is 1.9 N / mm^Two When the hollow ratio is 75%, the maximum stress is 1.5 N / mm^Two

Further, the fitting pieces 201 and the fitted grooves 202 are provided alternately along the upper edges of the left and right side plates 12 and 13 and the rear plate 11 so as to match the upper edges. Along the both side edges and the rear edge of the face plate 14, the same fitting piece 201 and fitting groove 20 are engaged with the fitting piece 201 and fitting groove 202 in the vertical direction.
The two are provided so as to be alternately arranged. Thereby, the upper end edges of the left and right side plates 12 and 13 and the rear plate 11, and the both side edges and the rear end edge of the upper surface plate 14 that match the upper end edges,
By fitting the fitting piece 201 and the fitted groove 202, which are assembled so as to face each other, they are easily and firmly coupled.

Similarly, the fitting pieces 201 and the fitted grooves 202 are alternately arranged at the lower end edges of the left and right side plates 12, 13 and the back plate 11, and the bottoms matching the lower end edges are provided. The same fitting pieces 201 and fitted grooves 202 are alternately arranged on both side edges and rear end edges of the face plate 15 so as to mesh with the fitting pieces 201 and fitted grooves 202 in the vertical direction. Set up. As a result, the left and right side plates 12,
13 and the lower end edges of the back plate 11 and the both side edges and the rear edge of the bottom plate 15 matching the respective lower end edges of the fitting piece 201 and the fitted groove 202, which are assembled so as to face each other. By fitting, they are easily and firmly connected.

Therefore, not only the strength and rigidity of the resin base bodies 20a to 20c forming the left and right side plates 12 and 13 and the rear plate 11 are secured, but also the fitting piece 201 and the fitted groove 202 are fitted together. Left and right side plates 1 depending on the structure
As for the assembling strength of the second and the rear plates 11 and the rear plate 11 and the upper plate 14 and the bottom plate 15 which are connected to each other above and below after assembling, sufficient strength and rigidity capable of withstanding a considerable load can be secured. .

Are integrally formed, and the fitting pieces 201 and the fitted grooves 202 are alternately arranged along the respective flange portions 14a and 15a, so that the top plate 14 and the bottom related to these fitting structures are formed. The rigidity of the peripheral edge of the face plate 15 can also be increased.

Further, since the loads received from above by the face plates 11 to 15 are different from each other, the back plate 1 is provided in order to receive the optimum load and reduce the weight as in the present embodiment.
1, a resin base body 20 that constitutes the left and right side plates 12, 13.
It is preferable that the hollow ratio be different for each of ac. Further, if approximately 75% or more of each of the face plates 11 to 15 is composed of the resin base body 20 set to the hollow ratio, it becomes possible to achieve a further weight reduction which cannot be achieved by conventional products.

For example, the bottom plate 1 out of the whole plates 11 to 15
If the other face plates 11 to 15 except 5 are constituted by the resin base body 20 set to the hollow ratio, the whole face plates 11 to 1
Approximately 75% of 5 is basically composed of the resin base body 20 having the same structure. Here, the lower limit value of “75” has a significance as a critical point for realizing the weight reduction while ensuring the rigidity of the entire outer casing 10 for a game machine, according to the investigation by the inventors.
