The pachinko machine main body 12 has an inner frame 12a, and the inner frame 12a is rotatably supported with respect to the outer frame 2 via hinges 10 and 11 provided at the left end of the outer frame 2. .
A play board 12b is attached to the inner frame 12a at a substantially central portion of the inner frame 12a except for a lower end portion, and a firing ball supply tray 12c and a surplus ball storage tray 12d are provided below the play board 12b. It is incorporated so as to protrude forward (toward the back of the paper of FIG. 1). Further, a handle 12e constituting the launching device is attached to the lower right corner (the left side in FIG. 1) of the inner frame 12a.
[0012]
The outer frame 2 is made of wood, and is constructed by assembling a pair of left and right vertical frame plates 3 and a pair of upper and lower horizontal frame plates 4 in a rectangular frame shape as shown in FIG.
The waist plate 5 attached to the outer frame 2 is also made of wood, and is attached to the front side of the lower sides of the left and right vertical frame plates 3. Therefore, the waist plate 5 projects forward from the vertical frame plate 3 by the thickness of the waist plate 5. And the waist board 5 reinforces the lower side of the outer frame 2 by bridging the left and right vertical frame boards 3.
The waist plate 5 has cutouts 50 at both left and right ends. The notch portion 50 has a configuration in which a lower part of both right and left ends of the waist plate 5 is cut out. Therefore, a part of the lower end of the vertical frame plate 3 is not covered with the waist plate 5 by the notch portion 50. Further, the notch portion 50 has a configuration in which the notch portion is further cut out in the left and right central position direction than the vertical frame plate 3, and forms a gap between the vertical frame plate 3 and the waist plate 5. An insertion passage 51 is formed between the vertical frame plate 3 and the waist plate 5 by the gap. Then, the locking member 7 of the decorative plate 6 is inserted into the insertion passage 51 as shown in FIG.
[0013]
The decorative plate 6 is formed from a synthetic resin material, and has a plate-shaped main body plate portion 60 as shown in FIG. On both left and right ends of the main body plate portion 60, side surface portions 61 erected along the edge are integrally formed, and on the upper edge, an upper surface portion 62 erected along the upper edge is integrally formed. Have been.
When the decorative plate 6 is attached to the waist plate 5, the main body plate portion 60 covers the front surface of the waist plate 5, the side surface portion 61 covers the side end surface of the waist plate 5, and the upper surface portion 62 covers the upper end surface of the waist plate 5. For this reason, the decorative plate 6 covers the waist plate 5 almost completely.
[0014]
A plurality of locking members 7 are integrally provided on the back surface of the decorative plate 6 as shown in FIG. One locking member 7 is provided near each of the left and right ends of the main body plate portion 60. As shown in FIGS. 4 and 5, these locking members 7 integrally form an elastic piece 70 protruding from the back surface of the main body plate part 60 and a folded piece 71 extending in a folded shape from the tip of the elastic piece 70. Prepare.
[0015]
The elastic piece 70 and the folded piece 71 are formed in a plate shape, and are formed such that the board width direction is parallel to the height direction of the decorative plate 6. Therefore, the elastic piece 70 is easily elastically deformed in the plate thickness direction, and is inclined in the left-right direction by the elastic deformation.
4 and 5, the elastic pieces 70 extend obliquely from both left and right ends of the main body plate portion 60 toward the center. Therefore, the tip of the elastic piece 70 is located closer to the left and right center than the base of the elastic piece 70.
The folded piece 71 extends from the distal end of the elastic piece 70 toward the main body plate 60 as shown in FIGS. The folded piece 71 extends obliquely from the tip of the elastic piece 70 toward the left and right center.
[0016]
Also, the elastic pieces 70 are provided with reinforcing ribs 80 and 81 for reinforcing the elastic pieces 70 as shown in FIGS.
The reinforcing ribs 80 and 81 are provided integrally with a part (base) of the elastic piece 70 on the main body plate portion 60 side. The reinforcing ribs 80 are provided at positions closer to the left and right centers of the main body plate portion 60 than the elastic pieces 70, and prevent the elastic pieces 70 from falling toward the left and right centers. On the other hand, the reinforcing ribs 81 are provided on the left and right end sides of the main body plate portion 60 with respect to the elastic pieces 70, and prevent the elastic pieces 70 from falling to the left and right end sides. Therefore, the reinforcing ribs 80 and 81 cooperate to prevent the elastic piece 70 from falling in the thickness direction.
[0017]
4 and 5, the reinforcing rib 80 is provided at a position avoiding a region sandwiched between the folded piece 71 and the main body plate portion 60 and at a position along the upper end edge of the elastic piece 70. . Therefore, the reinforcing ribs 80 can be easily formed without increasing the number of dies.
On the other hand, the reinforcing rib 81 is provided at the center of the plate width of the elastic piece 70 as shown in FIGS.
[0018]
Further, the main body plate portion 60 has a rib structure 63 on the back surface as shown in FIGS. The rib structure 63 is a structure having a plurality of ribs extending in the left-right direction and the up-down direction on the back surface of the main body plate portion 60, and reinforces the main body plate portion 60.
The reinforcing ribs 80 and 81 and the elastic piece 70 are formed integrally with the rib structure 63. Therefore, the reinforcing ribs 80 and 81 and the elastic piece 70 constitute a part of the rib structure 63.
[0019]
Next, a method of attaching the locking member 7 to the waist plate 5 will be described.
First, as shown in FIG. 1, the decorative plate 6 is pressed from the front to the back of the waist plate 5. Thereby, the locking member 7 is pushed into the insertion passage 51 as shown in FIG.
When the locking member 7 is pushed into the insertion passage 51, the pair of elastic pieces 70 is elastically deformed. The direction is a direction in which the pair of elastic pieces 70 expands to the left and right sides, and the pair of elastic pieces 70 urges in a direction sandwiching the waist plate 5. Therefore, the pair of elastic pieces 70 can be pushed straight into the waist plate 5.
Then, the elastic piece 70 passes through the insertion path 51 from the front to the back of the waist plate 5 while being elastically deformed.
[0020]
The elastic piece 70, the folded piece 71, and the entire decorative plate 6 are elastically deformed, so that the folded piece 71 passes through the insertion passage 51 and is arranged on the back surface of the waist plate 5. Then, the elastic piece 70, the folded piece 71, and the decorative plate 6 return elastically. Therefore, the folded piece 71 presses the back surface of the waist plate 5 by the elastic force of the elastic piece 70 and the elastic return of the folded piece 71 itself, and urges the back surface of the waist plate 5 toward the front side.
The elastic piece 70 is elastically deformed even when the locking member 7 is locked to the waist plate 5 as shown in FIG. Therefore, the elastic piece 70 always presses the folded piece 71 against the back of the waist plate 5, and the folded piece 71 always presses the waist plate 5.
[0021]
As described above, the decorative plate 6 is attached to the waist plate 5 with one touch.
As shown in FIG. 7, the folded piece 71 has a structure in which the distal end 7a is in contact with the waist plate 5, but the distal end 7a has a curved surface formed in a substantially semicircular cross section. Therefore, the folded piece 71 is locked to the waist plate 5 in a state where the waist plate 5 is not easily damaged.
[0022]
Next, a method of removing the locking member 7 from the waist plate 5 will be described.
The locking member 7 is operated from the back of the pachinko machine 1 to elastically deform the pair of elastic pieces 70 in such a direction as to expand to the left and right sides (see FIGS. 6 and 7). As a result, the folded piece 71 moves to the insertion path 51 side. Then, the locking member 7 is pushed toward the front surface of the waist plate 5, and the folded piece 71 is inserted into the insertion passage 51. Thereby, the locking member 7 is detached from the waist plate 5, and the decorative plate 6 is removed from the waist plate 5.
[0023]
The outer frame structure of the pachinko machine 1 is formed as described above.
That is, the locking member 7 has an elastic piece 70 and a folded piece 71 as shown in FIG. The elastic piece 70 is inserted into the insertion passage 51 of the waist plate 5 while being elastically deformed. Then, the folded piece 71 presses the back of the waist plate 5 toward the front using the elastic force of the elastic piece 70.
Therefore, the locking member 7 is easily attached to the waist plate 5 by the elastic deformation of the elastic piece 70. The locking member 7 has a structure for locking to the back of the waist plate 5. Therefore, the locking member 7 can be easily removed from the waist plate 5 by being operated from the back side of the waist plate 5. Thus, the locking member 7 has a structure that can be easily attached to and detached from the waist plate 5.
[0024]
The folded piece 71 presses the waist plate 5 from the back side to the front side (in the thickness direction) by the elastic force of the elastic piece 70 and the elastic force of the folded piece 71 itself. Therefore, the folded piece 71 is stably locked to the waist plate 5. For example, even if the thickness of the waist plate 5 varies, the folded pieces 71 stably press the waist plate 5 and are locked to the waist plate 5.
The folded piece 71 has a form that is folded from the tip of the elastic piece 70 and extends. Therefore, the folded piece 71 presses the waist plate 5 at a position away from the insertion path 51. Therefore, there is little possibility that the folded piece 71 will fall out of the insertion passage 51, and the waist plate 5 can be reliably pressed.
From the above, the decorative plate 6 can be easily attached to and detached from the waist plate 5 and can be stably attached to the waist plate 5.
[0025]
The elastic piece 70 is provided with reinforcing ribs 80 and 81 for reinforcing the base of the elastic piece 70.
Incidentally, the elastic piece 70 is configured to protrude from the back surface of the main body plate portion 60. Therefore, when the elastic piece 70 is elastically deformed, stress tends to concentrate on the base (a part of the elastic piece 70 near the rear surface of the main body plate portion 60). On the other hand, in this embodiment, reinforcing ribs 80 and 81 are provided at the base of the elastic piece 70. Therefore, the elastic piece 70 is hard to be broken, whereby the locking member 7 is stably locked to the waist plate 5.
[0026]
The reinforcing ribs 80 and 81 are formed integrally with a rib structure 63 for reinforcing the main body plate portion 60 provided on the back surface of the main body plate portion 60.
That is, the reinforcing ribs 80 and 81 also constitute a part of the rib structure 63 of the main body plate portion 60. Accordingly, the reinforcing ribs 80 and 81 reinforce the locking member 7 and also the main body plate portion 60, and the structure of the decorative plate 6 is facilitated by the common structure.
[0027]
Further, the insertion passages 51 are formed at the left and right ends of the waist plate 5 by forming cut portions 50 at part of the left and right ends of the waist plate 5 as shown in FIG. The insertion passage 51 is formed between the left and right edges of the waist plate 5 and the inner edge of the outer frame 2 (vertical frame plate 3). Therefore, the insertion passage 51 has a structure that can be easily formed without performing a boring process on the waist plate 5.
The elastic piece 70 has reinforcing ribs 80 and 81, and the elastic force can be easily adjusted by adjusting the height of the reinforcing ribs 80 and 81. Therefore, the pressing of the waist plate 5 by the folded pieces 71 can be easily designed and adjusted to a desired size.
[0028]
Further, the present invention is not limited to the above embodiment, but may be the following embodiments.
That is, in the above-described embodiment, the insertion passage 51 is formed by the cut portion 50 formed in the waist plate 5. However, a form in which a through hole is provided in the waist plate 5 to thereby form an insertion passage, and the locking member is inserted through the insertion passage may be adopted.
