For this reason, the assembly is troublesome, and the recent gaming machine main body 2 is mounted with various driving members and is becoming heavier, and therefore, an improvement in strength is required.
An object of the present invention is to provide a rectangular outer frame that is easy to assemble and is robust.
[0004]
[Means for Solving the Problems]
In the present invention, a rectangular outer frame on which a gaming machine main body having a pachinko gaming machine board is attached is made of an aluminum casting product (aluminum die-casting), and connecting ribs projecting inwardly are formed at upper and lower ends. The left and right vertical frame ridges and upper and lower horizontal frame ridges that are passed to the upper and lower ends of the vertical frame ridge pair and are respectively secured to the connecting ribs. The upper and lower horizontal frame rods are respectively connected in the horizontal direction between the respective end portions, and the both end portions are respectively fixed to the end portions of the vertical frame rods, and the end portions of the lower horizontal frame rods, It is coupled to any one of the lower end portions of the vertical frame ridge, and is more than the main cross-sectional area along the xy plane, the xz plane, or the angle along the longitudinal direction of the horizontal frame ridge or the transverse direction of the vertical frame ridge. It is characterized in that the end portion of the horizontal frame rod and the lower end of the vertical frame rod are connected via a reinforcing portion that secures a wide reinforcing joint surface. Here, the xy plane refers to a horizontal plane, and the xz plane refers to a plane parallel to a longitudinal section orthogonal to the main surface of the pachinko gaming machine (see FIG. 3). This means that it includes an inclined surface passing through an intersection line where the -y plane and the xz plane intersect.
[0005]
In such a configuration, the corner between the vertical frame rod and the horizontal frame rod is constituted by a connecting rib formed integrally with the vertical frame rod made of an aluminum cast product, and the horizontal frame rod is connected to the connecting rib. It is designed to be assembled. For this reason, sufficient assembling strength can be maintained. In addition, with such a strength guarantee, it is not necessary to use L-shaped metal fittings d and d 'or right-angled triangular reinforcing members as in the conventional configuration. Furthermore, in such a configuration, the reinforcing part that secures the reinforcing joint surface secures the joint on the above-described surface, so that the drag in the relative proximity direction between the horizontal frame rod and the vertical frame rod increases, and the connection Strength is improved.
[0006]
Here, as an example of such a configuration, the connecting rib formed at the lower end of the vertical frame rod is made into two parallel plate-like shapes protruding inward, and the plate-shaped connecting rib is formed at the end portion of the lower horizontal frame rod. A configuration is proposed in which a ridge-shaped reinforcing portion is formed which is fitted in between and rises from a main flange portion whose upper and lower surfaces are fixed to the plate-like connecting rib. In this configuration, a reinforcing joint surface is secured on the upper and lower fixed surfaces (xy plane) of the reinforcing portion to which the plate-shaped connecting ribs are solidified, and the inner back surface (xz) between the plate-shaped connecting ribs. Reinforcing joint surface is also secured to the surface), and a wide reinforcing joint surface can be secured. For this reason, the holding strength between the vertical frame rod and the lower horizontal frame rod is improved, and even if a large moment is applied between the vertical frame rod and the lower horizontal frame rod due to the side force, the rectangular outer frame Will not be deformed.
[0007]
In addition, reinforcing ribs may be formed at the corners between the inner side of the reinforcing part and the main collar part. In this case, even if the reinforcing part receives the force of the moment toward the inner side, the reinforcing part will not bend. Absent.
[0008]
Here, the horizontal frame rod is made of a synthetic resin, thereby preventing an increase in the weight of the outer frame. In particular, it becomes easy to form the reinforcing portion by molding with a synthetic resin.

As a result, the gaming machine main body 2 is mounted on the front portion of the rectangular outer frame 10 and various members provided on the back surface of the gaming board surface 5 face the rectangular outer frame 10.
[0018]
In such a configuration, the rectangular outer frame 10 is assembled by passing the upper and lower horizontal frame rods 20 and 30 to the upper and lower ends of the vertical frame rods 11a and 11b and fixing them respectively.
[0019]
Here, since the horizontal frame rods 20 and 30 are formed of a synthetic resin molding, the mounting holes 23 and 23, the reinforcing portions 32 and 32, and the like can be easily molded. Further, by using the synthetic resin material, the entire rectangular outer frame 10 can be reduced in weight.
[0020]
Thus, the rectangular outer frame 10 connects the horizontal frame rods 20 and 30 by the connecting ribs 12, 19a, and 19b, so that a separate member such as a metal fitting is not required. The number of parts is reduced, and the rectangular outer frame 10 can be made inexpensive, and the assembly is facilitated.
[0021]
And the rectangular outer frame 10 assembled | attached in this way will be juxtaposed on an installation island using each attachment hole 23,37 formed in the horizontal frame ridges 20,30.
