[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer frame of a gaming machine such as a pachinko machine or a slot machine.
[0002]
[Prior art]
A pachinko machine or a gaming machine such as a slot machine configured in accordance with the external shape of the pachinko machine has a rectangular outer frame to be attached to a hole mounting base (a so-called “island” mounting device). I have.
In general, the outer frame of a pachinko machine, etc., is made of two thick and thin plate materials, and each frame material is made into a rectangular shape, which is assembled into a rectangle, and a connecting bracket is attached to the corner portion, and secured with screws. It is common to form a frame. However, in recent years, an outer frame made of synthetic resin or the like instead of natural wood has been provided from the viewpoint of protecting forest resources and improving productivity.
[0003]
The outer frame made of synthetic resin is generally molded using a molding die. Naturally, the molding with this metal mold is made of natural wood because the entire outer frame can be molded as a whole according to the design, as well as the design can be freely selected. This makes it possible to produce a variety of outer frames that cannot be obtained from the company.
In addition, the outer frame made of synthetic resin can be molded from the recycled material of synthetic resin products, so it is also considered as one of recycled products, and is expected to be used in a wider range in the future.
[0004]
On the other hand, in addition to using this synthetic resin as a material, the use of thinned wood and the manufacture of an outer frame made of artificial wood using wood chips as a raw material have been proposed, and some practical applications have been realized. In particular, the outer frame made of wood chips has been attracting attention as an alternative to natural wood because it has improved manufacturing technology for artificial wood and has ensured the required strength, as well as being easily mass-produced.
[0005]
[Problems to be solved by the invention]
In this way, materials made of synthetic resin instead of natural wood board or materials made of artificial wood board have been put into practical use as the material of the outer frame, but at the same time it is not in natural wood board at the time of practical use Consideration is required. In particular, when synthetic resin is used as a material, it is necessary to consider in many respects, such as ensuring the required strength, increasing product accuracy, and considering the molding cost.
In the case of synthetic resin, if one vertical frame material is used for the outer frame, the mold automatically becomes large, resulting in an increase in manufacturing cost, and distortion due to thermal shrinkage during molding. There is a problem that accuracy is easily lowered, a problem that strength is inferior when the weight is reduced in consideration of weight, and the like.
[0006]
The problem of strength is the same when using an artificial wood board. When each of the vertical and horizontal frame portions of the outer frame is formed by a single frame made of an artificial wood board, it is necessary to provide some kind of reinforcement structure so that the strength of the various devices to be supported can be supported.
[0007]
[Means for Solving the Problems]
The present invention has been developed in view of such points, and the frame materials used for the left and right vertical frame portions and the upper and lower horizontal frame portions constituting the outer frame are shared and standardized, while the four corners are used.

In particular, in the present invention, the frame material constituting the vertical and horizontal frame portions and the corner members at the four corners are standardized, and the mutual connection is standardized so as to be shared, and management through reduction of the number of parts is facilitated. At the same time, the productivity is improved, and the outer frame is divided into a frame material and a corner member to reduce the size of the outer frame, thereby improving the productivity and improving the dimensional accuracy, and reducing the manufacturing cost. This means that mass production of high-quality products is possible.
[0009]
In more detail, the present invention is characterized by L-shaped corner members disposed at the four corners of the outer frame, and the vertical and horizontal frame portions extending between the corner members facing each other vertically and horizontally. The corner member is provided with a connecting piece integrally at each end of two connecting pieces extending at right angles, and the vertical and horizontal frame members are formed at the corners at both ends. Provided is an outer frame of a gaming machine comprising a connecting piece for connecting to the connecting piece of members, and assembling into a rectangular frame shape by connecting and connecting the connecting pieces together through a connecting tool There is to do.

Assembling can be easily and surely linked and connected by joining the connecting pieces 6 and 7, and a strong assembly can be achieved.
[0030]
[Example 2]
7 and 8 show a second embodiment of the present invention. This embodiment will be described with respect to an example in which the size of the entire frame, in particular, the vertical or horizontal dimensions can be easily changed by changing the corner member 5 in the first embodiment.
[0031]
As shown in the figure, the corner member 12 in this embodiment has a vertical connecting piece 12a shorter than the other of the two connecting pieces 12a and 12b, which is the same as the vertical and horizontal frame members 1 as described above. When the connection pieces 6 and 7 are connected to each other, the vertical dimension of the formed frame 2 is reduced by the length of the connection piece 12a.
In addition, about the Example described below including this Example, the same code | symbol is attached | subjected about the part same as a 1st Example, and the description is abbreviate | omitted.
[0032]

However, when the horizontal connecting piece 12b is shortened, the horizontal width of the outer frame 2 formed is reduced. become. However, when the length of the connecting piece is changed as in this example and the direction of the connecting pieces 6 and 7 formed on each piece is reversed as in the first embodiment, it is natural that the connection piece shown in FIG. Thus, it is necessary to prepare two kinds of corner members, and accordingly, the number of parts increases accordingly.
[0033]
[Example 3]
9 to 12 show a third embodiment of the present invention. This embodiment is an example in which the joining means for joining the corner member and the frame material or the frame materials is changed. The other parts are substantially the same as those of the first embodiment except for the parts related to the change of the joining means. Accordingly, in this embodiment as well, the same parts are denoted by the same reference numerals and the description thereof is omitted as described above.
[0034]
In this embodiment, the corner member 13 is formed with connecting pieces 14 and 14 projecting at right angles toward the inner ends of the two connecting pieces 13a and 13a, and connecting the corner members at the four corners in accordance with the connecting pieces.

At the time of joining, the connecting pieces 14 and 16 are brought into contact with each other in the form of a contact surface, and a bolt 18a as a coupling tool is inserted into the through hole 17 penetrating through both the connecting pieces, and the nuts 18b are tightened to connect the two pieces. As a result, the frame 2 is formed.
[0035]
Similarly, in the case of this embodiment, the connecting pieces 14 and 16 are both formed to have the same width as the connecting piece 13a and the frame member 15. Each piece is provided with two through-holes 17 in parallel and tightened and constrained through a connecting member composed of a bolt and a nut.
[0036]
[Example 4]
FIG. 13 shows that when the outer frame 2 is assembled by making one connecting piece 13a (vertical connecting piece) of the corner member 13 shorter than the other connecting piece in the third embodiment, the vertical dimension is reduced. This is the case.
This embodiment is based on the same idea as the second embodiment, and is intended to change the outer dimension of the outer frame 2 by changing the corner member. However, in the case of this embodiment, since the two connection pieces 20 formed on the corner member 19 are the same and are also common to the connection pieces 16 of the frame member 15, it can be dealt with by changing the direction. Therefore, it is sufficient to form one kind of corner member.
[0037]
[Example 5]
14 to 18 show a fifth embodiment of the present invention. This embodiment is different from the above embodiments in that the shape of each connecting piece of the corner member and the frame member is changed, and the horizontal frame member and the vertical frame member are individually formed.
[0038]
As shown in FIG. 15, in this embodiment, the connecting piece 22 projecting from the ends of the connecting pieces 21a, 21a of the L-shaped corner member 21 is longer and thinner than those shown in the previous embodiments. The connection pieces 23a and 24a formed at the end portions of the vertical and horizontal frame members 23 and 24 are formed to be thick. The vertical frame member 23 is adjusted to the length of the vertical frame portions 3a and 3b, and the horizontal frame member 24 is adjusted to the length of the horizontal frame portions 4a and 4b. The corner members 21 and 21 are connected.
[0039]
In this embodiment, each of the frame members is transferred to the corner members which are composed of one kind of corner member 21 and two kinds of frame members 23 and 24 and are arranged at the four corners, and the connection pieces 22 and 23a and 24a are connected to each other. Then, a bolt 26a serving as a connecting tool is inserted into a through hole 25 that penetrates through an overlapping joint piece, and a nut 26b is tightened to fix both of them together to form an outer frame 2. .
[0040]
[Example 6]
FIGS. 19 to 21 show another embodiment in the case of connecting a corner member and a frame material or frame materials. The embodiment shown here is characterized by a connector, and an example of connecting the frame members of the drawings will be described.
The plate-shaped frame members 27 and 27 are formed with connecting pieces 28 and 28 having a thickness of approximately one half at the ends, respectively, and projecting to the tip side of the contact surface (inner side surface) of these connecting pieces. The part 28a is formed with a recess 28b on the base end side, and the connecting pieces 28 and 28 are joined to each other in the form of a contact surface by meshing the protrusion and the recess.
[0041]
Next, metal coupling tools 29 and 29 having a U-shaped cross section are fitted from both side portions of the joint portion, and the two connecting pieces 28 and 28 overlapped are sandwiched and coupled.
A cutting portion 30 is provided at the edge of the frame member 27 and the connecting piece 28 to match the thickness of the connecting tool so as to receive and integrate the connecting tool piece and to ensure a firm fit. .
[0042]
This connection method is simple because it can be performed by overlapping the connecting pieces and fitting the connecting members, and can be firmly fixed. On the other hand, it is very easy to disassemble because it can be easily separated by removing the connector.
[0043]
Although the present invention has been described above for each of the embodiments, the frame members 1, 15, 23, 24, etc. used in common for the vertical and horizontal frame portions 3a, 3b, 4a, 4b, etc. A desired outer frame can be easily obtained by connecting and combining a small number of parts such as corner members 5, 12, 13, 19, and 21 commonly used for the four corners, and each part is made of synthetic resin. Since it can be manufactured by metal mold molding, such as metal and metal materials, there is an advantage that the manufacturing is easy and the productivity is excellent.
[0044]
In particular, since the corner members and the frame material are individually manufactured in a miniaturized state, it is possible to reduce the size of the mold and to reduce the manufacturing cost. Distortion can be suppressed and accuracy can be increased.
[0045]
Further, the outer frame of the present invention is manufactured because the number of parts is small and the assembly is uniform as described above, and the frame material 1 which is the central base material of each frame portion is used in both the vertical and horizontal directions. It is possible to greatly improve the performance.
[0046]
