FIG. 13 is a plan view of the outer-frame-side hinge fitting in a state in which the front frame 2 in which the outline is indicated by a two-dot chain line when the gaming machine main body is arranged at the attachment / detachment angular position is removed. FIG. 11 is an explanatory diagram (a cross-sectional view similar to FIG. 10) illustrating a situation when the pachinko machine PM is about to be inserted backward and forward into the pallet PL that transports the gaming machine.

  The lower hinge structure 200 includes an outer frame side hinge fitting 210 fixed to the lower left edge of the outer frame 1 and a front frame side hinge fitting 220 fixed to the lower left corner of the front frame 2. Is a hinge structure utilizing the fitting of the shaft pin and the shaft hole.

  The outer frame-side hinge fitting 210 is mainly composed of a flat plate-like hinge plate portion 211 extending in the front-rear direction and a hinge pin 213 that protrudes upward and is fixed to the center portion on the front end side of the hinge plate portion 211. The rear part of the hinge plate part 211 extends rearward and the left side is bent upward, and a fixed side part 212 extending along the inner surface of the left frame ridge in the outer frame 1 is formed.

  The hinge pin 213 is, for example, a cylindrical shape having a diameter of about 6 mm and a length of about 8 mm, and the leading end is chamfered into a tapered conical shape to form an introduction portion 213d. A disc-shaped flange portion 213t having a diameter of approximately 14 mm and a thickness of approximately 1 mm is formed at the intermediate portion of the hinge pin. The hinge plate portion 222 of the front frame side hinge fitting 220 is received by the flange portion to reduce the contact area. It is the structure which suppressed the sliding resistance by plates contacting directly. The hinge pin 213 is fitted into a pin hole formed in the hinge plate portion 211 of the outer-frame-side hinge fitting, and is fixed integrally by fixing means such as caulking or welding while the collar portion 312t is in close contact with the hinge plate portion 211. .

  The front frame-side hinge fitting 220 has a flat plate-like hinge plate portion 221 extending in the front-rear direction, and a pin receiving hole having an inner diameter somewhat larger than the diameter of the hinge pin 213 at the distal end portion of the hinge plate portion 221. The hole 223 is the main component. The rear portion of the hinge plate portion 211 extends rearward and the rear side is bent upward to form a fixed side portion 222 that extends upward along the rear surface of the front frame 2, and is fitted with a positioning pin on the front frame side. A pin hole for positioning the front frame side hinge metal fitting 220 and a screw insertion hole for inserting a metal fitting fixing screw are formed.

  The outer frame side hinge fitting 210 and the front frame side hinge fitting 220 are formed by punching and bending, for example, a steel sheet having a plate thickness of about 2.3 to 3.2 mm into a predetermined unfolded shape shown in the drawing, In 210, a hinge pin 213 is fixed to the hinge plate portion 211, and surface treatment such as chromate treatment is performed as necessary.

  The outer frame side hinge fitting 210 is positioned by abutting the fixed side portion against the lower left inner peripheral corner portion of the outer frame 1 where the curtain plate and the reinforcing frame and the left frame rod cross each other. The outer frame side hinge fitting 210 is positioned and fixed to the lower left corner of the outer frame 1 by rivet fastening the part and fastening the fixing side part on the curtain plate side by screws. The front frame side hinge fitting 220 is positioned by fitting a pin hole formed in the fixed side portion 222 to a positioning pin formed in the lower end on the back surface side of the front frame 2, and a pin insertion hole in the fixed side portion The front frame side hinge metal fitting 220 is positioned and fixed to the lower left corner of the front frame 2 by fastening the metal fitting fixing screw through the screw. In the mounting posture, the central axis of the hinge pin 213 in the outer frame side hinge fitting 210 is disposed on the same axis as the bearing hole 123 of the outer frame side hinge fitting in the upper hinge structure 100 described above, and the upper and lower common swing shafts are arranged. It is formed.

  When the outer frame side hinge fitting 210 and the front frame side hinge fitting 220 are respectively attached in this way, the lower hinge structure 200 is configured to be detachable using the fitting of the hinge pin 213 and the pin receiving hole 223, and the fitting state The front frame side hinge fitting 220 is disposed so as to be rotatable and slidable around the central axis of the hinge pin 213, whereby the front frame 2 is hingedly connected to the outer frame 1 so as to be swingable and openable.

Here, in this pachinko machine PM, the lower region of the ball pan unit 6 located above the lower hinge structure 200 is projected forward to cover the entire upper part of the front frame side hinge fitting 220 because of the requirement in the body design. The front frame side hinge fitting 220 is configured not to be directly visible to the player. That is, the front end of the front frame hinge member 220 is adapted to be disposed in a position in dimension of the rear indicated by D _R in FIG. 10 of the front end face of the Tamasara unit 6 located the upper .

  For this reason, in order to attach the gaming machine main body in which the ball tray unit 6, the game board 10, and the like are assembled to the front frame 2 to the outer frame 1, If the receiving hole 223 is to be fitted and connected, a region near the fitting and connecting portion is covered with the main body of the gaming machine and cannot be aligned, and there is a problem that it is extremely difficult to connect the hinges.

  Therefore, in the lower hinge structure 200, the pin receiving hole 223 is fitted and connected to the hinge pin 213, and the hinge of the outer frame side hinge metal fitting is at the attachment / detachment angle position where the front frame 2 is opened by the attachment / detachment angle θ. A contour line 215 of the lower end portion of the gaming machine main body projected on the plate 211 is drawn and formed on the upper surface of the hinge plate 211 as indicated by a dotted line in FIG.

  Therefore, if the lower end corner of the front frame 2 is placed on the hinge plate 211 in accordance with the contour line 215 drawn on the upper surface of the hinge plate 211, the center axis of the hinge pin 213 and the pin receiving hole 223 are inevitably formed. They are arranged on the same axis so as to coincide with the central axis, and these are fitted and connected. Therefore, when the front frame side hinge fitting 220 is hinge-connected to the outer frame side hinge fitting 210, the operator sets the lower end corner portion of the front frame 2 in accordance with the contour line 215 drawn on the outer frame side hinge fitting 210. The hinge pin 213 and the pin receiving hole 223 can be fitted simply by placing them, and the outer frame side hinge fitting 210 and the front frame side hinge fitting 220 can be easily hingedly connected.

  The contour line 215 is formed on a die for punching the outer frame side hinge fitting 210 and is configured to be drawn on the upper surface of the hinge plate 211 along with the punching of the outer frame side hinge fitting 210. . For this reason, in addition to being able to form the contour line 215 in one step of the conventional die-cutting press processing, the contour line 215 is formed by pressure molding, so that it can be contoured even if surface treatment or degreasing with a solvent is performed. The line never disappears and does not wear out by opening and closing the front frame.

  Further, since the contour line 215 is drawn and formed in accordance with the projected shape of the lower end portion of the gaming machine main body at the attaching / detaching angular position of the upper hinge structure 100, the contour line 215 is formed on the hinge shaft 113 of the upper hinge structure 100 at this angular position. The flat surfaces 113b and 113b and the groove surface of the parallel groove portion 124a formed in the guide hole 124 of the hinge plate portion are parallel to each other. Therefore, with the lower end corner of the gaming machine body aligned with the contour line 215 as described above, the lower hinge structure 200 is hinged and the upper end of the front frame is tilted to introduce the hinge shaft 113 into the guide hole 124. By doing so, it is possible to easily perform the hinge connection between the front frame side hinge fitting 110 and the outer frame side hinge fitting 120 without complicated operations such as angular alignment.

  The contour line 215 is also effective when the gaming machine main body is removed from the outer frame 1. By opening the gaming machine main body and matching the contour line 215, the hinge shaft plane portions 113 b and 113 b that are difficult to see The attachment / detachment angle position at which the angle with the groove surface of the parallel groove portion 124a of the guide hole is parallel can be easily set. In addition, this makes it possible to prevent galling between the guide hole and the hinge shaft associated with the angular alignment, wear due to this, and the like. Therefore, according to the hinge mechanism composed of the upper and lower hinge structures 100 and 200, the hinge mechanism can be easily attached and detached from the outer frame and the front frame side, has good workability, and has long-term reliability. Can be provided.

Now, the lower hinge structure 200 as described above, while being arranged positioned dimension of rear indicated by D _R to the front frame side hinge bracket 220 in FIG. 10 of the front end face of the Tamasara unit 6, the outer In the frame side hinge fitting 210, the front end portion of the hinge plate 211 extends forward from the hinge plate 221 of the front frame side hinge fitting 220, and further D in FIG. It is configured so as to protrude forward by the dimension indicated by _F.

  For this reason, the pallet PL for transporting the vertical gaming machine described in the background section, that is, a large number of U-shaped support frames 50 that are open inward and face each other and extend vertically are arranged side by side on the pallet. In a vertical gaming machine transport pallet PL configured to sandwich the pachinko machine between the front and rear frame pieces 51, 52 of the U-shaped support frame to prevent the fall, the pachinko machine PM is mistakenly turned backwards and forwards. When trying to insert, the lower surface of the hinge plate 211 of the outer frame side hinge fitting 210 abuts on the upper end of the frame piece 52 for supporting the rear surface of the support frame, and abuts on the ball tray unit 6 positioned above this. It is supposed not to.

  That is, as in the present embodiment, the pachinko machine having a configuration in which the front-frame-side gaming machine component located above the front-frame-side hinge fitting 220 is disposed to protrude forward from the front-frame-side hinge fitting 220. Then, when the outer frame side hinge metal fitting 210 has the same forward projecting dimension as the front frame side hinge metal fitting 220, the frame piece of the support frame passes through the front of the lower hinge structure 200 and the gaming machine component on the front frame side. Can abut. However, in the lower hinge structure 200 of this configuration, the hinge plate 211 of the outer frame side hinge fitting 220 extends forward from the hinge plate 221 of the front frame side hinge fitting 220, and further the ball tray unit 6 positioned above the hinge plate 211 It is configured to project forward from the front end surface.

  Therefore, when the pachinko machine PM is mounted on the transport pallet PL, even if the front and rear surfaces of the machine body with respect to the support frame 50 are mistakenly inserted between the left and right support frames, the hinge of the outer frame side hinge fitting 210 The lower surface of the plate 211 is in contact with the support frame, and scratch marks are not generated or damaged on the gaming machine components on the front frame side such as the ball tray unit 6.

  Therefore, according to the lower hinge structure 200 described above, when the pachinko machine PM is mounted on the transport pallet PL, even if the front and rear surfaces of the machine body are erroneously inserted into the left and right support frames, A lower hinge structure that does not damage the gaming machine components on the frame side can be provided.
