Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an outer frame of a pachinko machine.

[0002]

2. Description of the Related Art Generally, an outer frame of a pachinko machine is formed in a rectangular shape by a pair of horizontal frame plates facing vertically and a pair of vertical frame plates facing left and right. By the way, this kind of outer frame is usually formed of wood (raw wood or plywood), and the horizontal frame plate and the vertical frame plate are formed separately and later joined at ends orthogonal to each other. I have. As a conventional connection structure of such an end portion, a structure is known in which a nail is driven into and fixed between orthogonal end portions of a corner portion. As another coupling structure, a metal fitting is applied to a corner portion as disclosed in Japanese Patent Application Laid-Open No. 8-336653, and the metal fitting is attached to both the end of the orthogonal horizontal frame plate and the vertical frame plate. 2. Description of the Related Art A structure is known in which an end on the side of the horizontal frame plate and an end on the side of the vertical frame plate are fixed to each other via metal fittings.

[0003]

However, in the former connection structure using a nail, there are problems that the connection strength is inevitably low and rattling occurs with time. In addition, in the latter connection structure using the metal fittings, since the connection is indirect via the metal fittings, sufficient bonding strength is provided unless screws are screwed and connected at a plurality of locations on the horizontal frame plate side and the vertical frame plate side, respectively. Therefore, not only the metal fittings but also a large number of screws are required, which leads to an increase in cost, and requires two types of work, that is, joining the fittings to the horizontal frame plate and joining the fittings to the vertical frame plate. There was a problem that became complicated. Furthermore, as described above, when a nail is used, the bonding strength is weak and loose, and when a metal fitting is used, the bonding strength is not as large as apparent due to indirect bonding. The thickness of the frame plate and the vertical frame plate is not less than a certain value (generally 1
9 mm or more), and the material cost was high. Further, there is a problem that the area of the internal space limited by the horizontal frame plate and the vertical frame plate is correspondingly small.

[0004]

In order to solve the above-mentioned problems, the invention according to claim 1 comprises a pair of vertically opposed horizontal frame plates,
An outer frame of a pachinko machine formed in a rectangular shape by a pair of left and right vertical frame plates, wherein ends of the horizontal frame plates and the vertical frame plates that intersect at right angles to each other are directly connected by screws. In addition, this is an outer frame of a pachinko machine in which the thickness of each of the horizontal frame plate and the vertical frame plate is set to approximately 10 mm to 16 mm.

[0005] In the first aspect of the present invention, since the horizontal frame plate and the vertical frame plate are directly connected by screws, the bonding strength is increased as compared with the connection by nails. In addition, since no metal fitting is used, the cost is reduced, and the joining work is simplified, and the workability is improved. Further, by such a coupling structure, it is not necessary to keep the thickness of the horizontal frame plate or the vertical frame plate at a certain value or more in consideration of the strength reduction as in the related art. Particularly, in the present invention, the horizontal frame plate and the vertical frame plate are not required. The thickness of each is set to approximately 10 mm to 16 mm, so that the material cost is reduced as compared with the conventional outer frame having a thickness of 19 mm or more, and the area of the internal space limited by the horizontal frame plate and the vertical frame plate Therefore, the degree of freedom in the arrangement of the mechanical plate of the pachinko machine accommodated in the outer frame, the wiring of the electric circuit, and the like is increased.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. An outer frame 1 of a pachinko machine according to an embodiment of the present invention, which is entirely shown in a perspective view in FIG. 1, includes a pair of vertically opposed horizontal frame plates 2 and 3 and a pair of left and right opposed vertical frame plates 4.
5 form a rectangle. The horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5 are formed of high strength plywood, and are individually formed in a predetermined size and shape as shown in the figure by cutting each plywood.

Here, the upper horizontal frame plate 2 and the left and right vertical frame plates 4 and 5 have substantially the same width, but the lower horizontal frame plate 3 is formed to be slightly wider than these. As shown in the figure, a part of the vertical frame plates 4, 5 protrudes forward from the lower ends thereof.
A front frame receiving plate 6 is mounted between lower end portions of the left and right vertical frame plates 4 and 5. The front frame receiving plate 6 has a flat plate shape, and its lower end is mounted on a forwardly projecting portion of the lower horizontal frame plate 3. Metal fittings for attaching a front frame (not shown) to a corner where the upper horizontal frame plate 2 and the vertical frame plate 4 on the left side in the figure intersect and a lower portion of the vertical frame plate 4 adjacent to the front frame receiving plate 6. 7, 8 are attached respectively. The structure and operation of these front frame receiving plates 6 and metal fittings 7 and 8 are well known, and description thereof is omitted.

Next, the connection structure of the outer frame 1 will be described. The upper and lower end surfaces of the vertical frame plates 4 and 5 are cut at right angles to the longitudinal direction of the corresponding vertical frame plates 4 and 5, respectively. In the illustrated combined state, the upper end surfaces of the left and right vertical frame plates 4 and 5 are in parallel with and contact with the lower surfaces at both ends of the upper horizontal frame plate 2, and the lower end surfaces of the vertical frame plates 4 and 5 are the same. Are in parallel with the upper surfaces of both ends of the lower horizontal frame plate 3 and are in contact therewith. With such a structure, the horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5 are assembled so as to cross each other at right angles.

The horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5 respectively have 2
They are connected to one another by screws 9, 9. Screw 9,
9 and the positional relationship at each of these corners are the same at any of the corners. A typical connection structure at the upper right corner in FIG. 1 will be described below with reference to FIGS. 2 and 3.

As shown in FIGS. 2 and 3, screws 9, 9 are provided on the upper side of the horizontal frame plate 2 at the right end of the upper horizontal frame plate 2 to face the vertical frame plate 5 from above the horizontal frame plate 2. Vertical frame plate 5 penetrating
Is screwed down to the appropriate depth. Here, the screwing positions of the screws 9, 9 (the positions in the horizontal direction with respect to the horizontal frame plate 2) are set such that the screws 9, 9 are aligned at appropriate intervals in the width direction of the horizontal frame plate 2. Further, the heads 9a, 9a of the screws 9, 9 are embedded in the upper horizontal frame plate 2 in the coupled state shown in the figure, and the upper end surface is the upper surface 2 of the horizontal frame plate 2.
It is almost flush with a. As described above, the screws 9 are selected to have such a length as to penetrate into the vertical frame plate 5 to an appropriate depth.

Here, the screws 9, 9 are provided with a positive engaging hole for engaging with a driver in the head 9a, 9a in the illustrated example, but are provided with a negative engaging hole. It may be. Although the screws 9 are made of coarse threads in the drawing, any other screws may be used.

Further, with the above-described coupling structure using the screws 9 to 9, it is not necessary to keep the thickness of the horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5 large in order to prevent a reduction in strength. In this connection, in the present embodiment, the thickness T1 of the horizontal frame plates 2 and 3 and the thickness T2 of the vertical frame plates 4 and 5 are less than 19 mm, and in particular, approximately 1 mm.
Set to 0 to 16 mm, and the dimensional tolerance is 10 ^-0.2 mm to 1
6 ^+0.2 mm. Further, the plate thicknesses T1 and T2 are set equal.

As described above, in this embodiment, the horizontal frame plates 2 and 3
And the vertical frame plates 4 and 5 are directly connected by screws 9 and 9 at each corner, so that the connection strength is increased as compared with the connection by nails, and since no metal fitting is used, the cost is reduced and the connection is further reduced. Work is simplified, and workability is improved. The thickness T1 of the horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5
Is set to approximately 10 to 16 mm, so that the material cost is reduced as compared with the conventional outer frame having a thickness of 19 mm or more and limited by the horizontal frame plates 2 and 3 and the vertical frame plates 4 and 5. The area of the internal space S is increased, and therefore, the degree of freedom in the arrangement of the mechanical plate of the pachinko machine accommodated in the outer frame 1 and the wiring of the electric circuit is increased. Further, conventionally, the vertical frame plate requires additional processing to reduce the thickness by partially providing a concave portion in order to avoid interference with other members of the pachinko machine. Because the thickness of plates 4 and 5 is thin,
Such additional processing becomes unnecessary. Further, since the amount of wood used is reduced, a great effect is produced in terms of resource conservation.

In the above embodiment, two screws 9 are used at each corner, but any number of screws 9 may be provided. Prior to screwing in the screws 9, holes for guiding these may be provided in advance from the horizontal frame plates 2, 3 to the vertical frame plates 4, 5. In addition, in the above embodiment, the end faces of the vertical frame plates 4 and 5 are screwed in a state where the end faces of the horizontal frame plates 2 and 3 are simply abutted at right angles to each other. 5 and the end portions of the horizontal frame plates 2 and 3 may be cut obliquely at an angle of 45 ° and abutted, or a tenon joint structure may be used, or an adhesive may be used together. In addition, the thickness T1 of the horizontal frame plates 2 and 3 and the thickness T2 of the vertical frame plates 4 and 5 are set to be equal, but have different thicknesses if the condition of approximately 10 to 16 mm is satisfied. Is also good.

[0015]

According to the first aspect of the present invention, since the horizontal frame plate and the vertical frame plate are directly connected to each other at the corners by screws, the bonding strength is increased as compared with the connection by nails, and no metal fitting is used. In addition, the cost is reduced, and the joining operation is simplified, and the workability is improved. Also, since the thickness of the horizontal frame plate and the thickness of the vertical frame plate were set to approximately 10 to 16 mm,
As compared with the conventional outer frame having a thickness of 19 mm or more, the material cost is reduced, and the area of the internal space defined by the horizontal frame plate and the vertical frame plate is increased, so that the pachinko machine accommodated in the outer frame is provided. This increases the degree of freedom in the arrangement of the mechanism plate and the like and the wiring of the electric circuit. Further, conventionally, the vertical frame plate requires additional processing to reduce the thickness by partially providing a recess in order to avoid interference with other members of the pachinko machine. Since the thickness is small, such additional processing is not required. Furthermore, because the amount of wood used is reduced,
It also has a great effect in terms of resource conservation.
