The inner space between the left and right frame parts 13 and 14 in the housing frame 10 is formed to be about 1 to 2 mm larger than the width dimension of the decorative plate 21, and the inner surface distance between the upper and lower frame parts 11 and 12 is several times larger than the height dimension of the decorative plate 21. It is formed large about mm. Each part of the housing frame 10 is formed with tongue-plate-shaped or corner-frame-shaped plate portions 11 a, 12 a, 13 a, and 14 a that protrude from the inner surface of each frame part toward the inside of the housing frame 10. Each of the contact plate portions 11 a, 12 a, 13 a, and 14 a is formed in the frame so as not to protrude rearward of the housing frame 10, and is configured such that the rear end surface of the housing frame 10 is flat.
[0023]
On the other hand, on the back side of the decorative plate 21, the plate receiving portions 41a, 42a, 43a, and 44a (see FIGS. 4 to 13 are described in detail later) in accordance with the formation positions of the plate portions 11a, 12a, 13a, and 14a. Is formed. Each of the contact plate receiving portions 41a, 42a, 43a, 44a is formed by counterboring the back surface of the decorative plate 21 by the thickness of the contact plate portion according to the position and shape of the contact plate portions 11a, 12a, 13a, 14a. When the decorative plate 21 is accommodated and held in the accommodating frame 10, the rear end surface of the accommodating frame 10 and the back surface of the decorative plate 21 are aligned and flattened.
[0024]
Now, in the storage frame 10 configured as described above, the locking mechanisms 50 are disposed at the two left and right positions of the lower frame portion 12. A side sectional view of the vicinity of the locking mechanism 50 viewed in the direction of arrow IV in FIG. 3 is shown in FIG. 4, and a perspective view of the mechanism 50 viewed from the back side of the housing frame 10 is shown in FIG. The locking mechanism 50 will be described with reference to the drawings.
[0025]
The locking mechanism 50 is mainly configured by a locking metal fitting 51 that is attached so as to sandwich the lower frame portion 12 and protrudes upward. The locking bracket 51 includes a base portion 51a supported on the upper surface of the lower frame portion 12, a front side of the base portion 51a bent upward and a locking side portion 51b protruding upward, and a rear side of the base portion 51a bent downward. The rear side 51c that extends downward, the lower part of the rear side 51c is folded forward, extends parallel to the base 51a, and sandwiches the lower frame 12 up and down, and the front end side of the sandwiching side 51d faces downward It is composed of a fixed side portion 51e or the like that is bent in the direction and extends downward and through which a screw 58 is inserted.
[0026]
The distance between the rear surface of the locking side portion 51b and the rear end surface of the rear side portion 51c, that is, the front-rear dimension of the upper surface of the base portion 51a is set to be the same as or slightly smaller than the plate thickness of the decorative plate 21. . Further, the upper end portion of the locking side portion 51b is gently bent toward the front, smoothly receiving and guiding the lower end portion of the decorative board 21, and preventing the surface of the decorative board from being scratched. The locking bracket 51 is formed of a metal material such as a stainless steel plate or a cold-rolled steel plate having a thickness of about 1 to 2 mm into a shape shown in the drawing using a known processing means such as punching, bending, or press forming, and if necessary. Then, it is formed by applying the required surface treatment.
[0027]
On the other hand, the rear edge of the lower frame portion 12 is cut out by the thickness of the locking metal 51 at the attachment position of the locking metal 51 to form a receiving notch 12c. The rear side 51c of the locking bracket 51 is received in the receiving notch 12c, and the rear end surface of the rear side 51c is flush with the rear end surface of the receiving frame 10 including the left and right lower frame portions 12. Are arranged. A cylindrical boss 12b that supports the front surface of the fixed side portion 51e is formed below the receiving notch 12c, and a screw receiving portion that receives the screw 58 is formed at the center thereof.
[0028]
Further, corner frame-shaped contact plate portions 12 a and 12 a are formed at the left and right ends of the lower frame portion 12 so as to connect the lower frame portion 12 and the left and right frame portions 13 and 14. On the left and right corners on the side, there is formed a pad receiving part 42a that is counterbored by the thickness of the pad 12a according to the shape of the pad 12a. The lower end edge of the decorative plate 21 has a corner on the back side cut obliquely to form a flank 42e.
[0029]
The locking metal 51 is placed on the upper surface of the lower frame 12 in accordance with the position where the receiving notch 12c is formed, and the locking metal 51 is slid forward to move the base 51a and the clamping side part. The lower frame portion 12 is fitted and connected so as to sandwich the lower frame portion 51d, and the screw 58 is screwed and fastened to the boss 12b through the attachment hole from the rear of the fixed side portion 51e to be attached to the lower frame portion 12.
[0030]
When the locking metal fitting 51 is thus attached, the base portion 51 a is supported on the upper surface of the lower frame portion 12, and the locking side portion 51 b is disposed so as to protrude upward on the front side of the lower frame portion 12. The rear end surface of the rear side portion 51 b is disposed on the same plane as the rear end surface of the storage frame 10, and the locking side portion 51 b has a longitudinal dimension between the rear surface and the rear end surface of the storage frame 10 of the decorative plate 21. It is disposed in the front-rear direction position that is the same size as the plate thickness or slightly smaller.
[0031]
When the game board 20 is mounted on the locking mechanism 50 configured as described above, the left and right edges of the decorative board 21 from the front side of the game board 20 with the glass door 5 and the upper ball tray 6 opened. The game board 20 is supported in a slightly forward tilted posture by gripping the portion, and the lower end portion of the decorative board 21 is inserted into the housing frame 10 obliquely from above the locking side portion 51b.
[0032]
Here, as shown in FIGS. 3 and 4, the height of the contact plate portion 12 a is formed to be larger than the protruding height of the locking side portion 51 b. For this reason, when the lower end portion of the decorative plate 21 is inserted obliquely into the housing frame, the left and right contact plate receiving portions 42a are respectively guided by being engaged with the front surface of the contact plate portion 12a, and the decorative plate 21 is moved downward. By sliding and moving, the two locking side portions 51b can be engaged at the appropriate position on the front surface of the decorative board. Since the upper end portion of the locking side portion 51b is gently bent toward the front, the decorative plate 21 slid downward is guided smoothly to the base portion 51a at the lower end portion. The side part 51b and the base part 51a are elastically deformed to receive the decorative board 21 in an inclined posture. As a result, the game board 20 is elastically biased and supported on the base portion 51a in a forward inclined posture.
[0033]
Further, since the flank 42e is formed at the lower end of the back surface of the decorative board 21, the lower end of the decorative board 21 can be attached to the housing frame 10 even when the game board 20 is inserted or removed in an inclined posture or rocked up and down. Even if the back set board 30 is closed and held so as to be in close contact with the rear end face of the storage frame 10 without protruding rearward from the rear end face, excessive stress is applied to the back set board 30. Is not generated.
[0034]
Further, the rear end side of the locking metal fitting 51 is bent into a U-shape to form a holding side portion 51d so that the lower frame portion 12 is held. For this reason, even if a force that tilts the locking side 51b forward acts and the locking side 51b and the base 51a are elastically deformed, the holding side 51d transmits this force to the lower frame 12. So that it does not act directly on the fixed side 51e. Therefore, an excessive bending moment or pulling force does not act on the boss 12b via the screw 58, and the boss 12b is not broken or the screw receiving portion is not damaged. In addition, by bending the locking fitting in this way, the length of the elastically deformable region can be increased, and a locking mechanism that is flexible and difficult to plastically deform can be configured in a small size.
[0035]
In the embodiment, the locking side portion 51b of the locking bracket is bent at a right angle with respect to the base portion 51a, and the front-rear dimension between the rear surface of the locking side portion 51b and the rear end surface of the housing frame 10 is the decorative plate 21. However, the locking mechanism 50 is not limited to such a configuration, and can lock the lower end portion of the decorative plate 21. If it is. For example, in the case where the same locking metal fitting as in the embodiment is provided, a gap slightly larger than the thickness of the decorative plate 21 is provided between the lower end of the locking side and the rear end surface of the housing frame. The locking side part 51b is formed at a right angle with respect to the base part 51a with a space slightly smaller than the thickness of the decorative plate 21 between the upper part of the locking side part and the rear end surface of the housing frame. Alternatively, it may be bent at a small angle and protrude in a slightly tilted posture. In such a locking mechanism, even if there is some variation in the thickness of the decorative plate 21, the locking bracket elastically absorbs, and a gap is formed between the decorative plate and the locking bracket is excessive. No stress is generated.
[0036]

(That is, so as to press the decorative plate 21 backward).
[0043]
Between the rear end surface of the bearing boss 11c and the contact plate portion 11a, an opening portion 11d that communicates the upper frame portion 11 up and down is formed. The opening portion 11d is formed in accordance with the arrangement position and the swing locus of the fixing metal fitting 63 and the temporary fixing metal fitting 65, and the respective leading ends of the fixing metal fitting 63 and the temporary fixing metal fitting 65 are passed through the opening portion 11d and the upper frame portion 11 is formed. It can be protruded downward or accommodated in the upper frame portion 11.
[0044]
The temporary support fixing mechanism 60 inserts the operation bolt 61 from the front side of the front frame 2 into the bearing hole of the bearing boss 11c, and the washer 62, the fixing bracket 63, the collar 64, The stoppers 65 are sequentially engaged and supported, and the nut 67 is screwed onto the male screw part via the thick plate washer 66 and tightened to be attached to the upper frame part 11. Here, the fixing metal fitting 63 and the temporary fixing metal fitting 65 are engaged with the engagement connecting portion 61b so that the extending direction of the lever portion 63a and the extending direction of the arm portion 65a are perpendicular to each other with a relative angle of 90 degrees. The metal fitting is attached to the operation bolt 61 so as to be swingable integrally while maintaining an orthogonal posture.
[0045]
The fixing bracket 63 is supported by a washer 62, and is configured to slide relative to the annular region where the rear end surface of the bearing boss 11c and the washer 62 are in contact with each other when the operation bolt 61 is rotated. Has been. For this reason, the operation bolt 61 can be rotated with a light operation force, and the fixing bracket 63 and the temporary fixing bracket 65 can be smoothly swung.
[0046]
When the fixing metal fitting 63 and the temporary fixing metal fitting 65 are assembled in this way, the fixing metal fitting 63 is moved downward from the upper frame portion 11 (inward of the housing frame 10) by rotating the operation bolt 61 from the front side of the front frame 2. And a fixed position (state of FIG. 8 (a)) for fixing the decorative plate 21 positioned in the accommodated posture and an open position (FIG. 8A) for releasing the engagement with the decorative plate 21 by being stored in the upper frame portion 11. 8 (b)). In addition, when the fixing metal fitting 63 is positioned at the open position, the temporary attachment metal fitting 65 is disposed at the temporary attachment position protruding inward of the accommodation frame 10, and the game board 20 is detachably accommodated in the accommodation frame 10. The game board is engaged with the housed game board 20 and temporarily supported in the housed posture.
[0047]
On the other hand, an upper edge engaging portion 41 is formed at the center of the upper edge of the decorative plate 21. The upper edge engaging portion 41 includes a backing plate receiving portion 41 a formed on the back side of the decorative plate 21, an upper side portion 41 b serving as the upper end surface of the decorative plate 21, and a temporary fitting receiving groove formed on the front side of the decorative plate 21. 41c, the upper end corner where the abutting plate receiving portion 41a and the upper side portion 41b cross each other is cut obliquely and formed into a sloped shape, and a sloped shape between the upper side portion 41b and the temporary fastener receiving groove 41c. It is composed of the formed locking surface 41f and the like.
[0048]
Among these, the backing plate receiving portion 41a is configured so that the back surface side of the decorative plate 21 is a backing plate in accordance with the formation position and shape of the backing plate portion 11a that is formed to protrude from the upper frame portion 11 toward the inside of the housing frame 10. It is formed by counterboring the thickness of the portion 11a, and when the game board 20 is accommodated in the accommodating frame 10, the abutting plate portion 11a is received by the abutting plate receiving portion 41a, and the rear end face of the accommodating frame 10 and the decorative plate The back surface of 21 is aligned with the front and back to form a flat back surface.
[0049]
Here, the introduction surface 41e is the introduction side portion of the temporary fixing metal fitting in the temporary fixing position when the lower end portion of the decorative plate 21 is engaged with the locking mechanism 50 and the game board 20 is swung in the closing direction. The introduction side portion 65e is formed so as to ride on the introduction surface 41e. The locking surface 41f is formed in alignment with the position of the locking side portion 65f of the temporary fixing metal fitting 65, and engages with the locking side portion 65f when the game board 20 is stored in the storage frame 10. Thus, the game board 20 is formed so as to be temporarily fixed in the storage posture.
[0050]
Now, the operation of the temporary support fixing mechanism 60 configured as described above will be described first from the case where the game board 20 is mounted on the storage frame 10.
[0051]
The operator opens the glass door 5, rotates the operation bolt 61 from the front side of the front frame 2 using a hexagon wrench or the like, swings the fixing bracket 63 upward, and stores it in the upper frame portion 11. In the open position. At this time, the temporary fixing metal fitting 65 is disposed downward, and the distal end side of the arm portion is disposed at a temporary fixing position that protrudes inward of the housing frame 10 from the opening 11d of the upper frame portion 11 (see FIG. 9). . Note that the left and right fixing mechanisms 80, which will be described later, are also operated to rotate the operation bolts 82 so that the fixing bracket 81 is swung downward (or upward).
[0052]
Then, using the locking mechanism 50 described above, the lower end portion of the decorative plate 21 is obliquely inserted into the housing frame 10 and engaged with the locking bracket 51, and the game board 20 is tilted forward on the base portion 51a. To be elastically supported. In this state, when the operator weakens the force in the forward tilt direction, the upper part of the game board 20 is swung rearward by the elastic force of the locking metal 51, and the upper edge of the decorative board 21 as shown by the solid line in FIG. The introduction surface 41 e of the engagement portion 41 is supported in a temporary support posture in contact with the introduction side portion 65 e of the temporary fixing metal fitting 65.
[0053]
When the operator presses the upper portion of the game board 20 backward from this temporary support posture, the arm portion 65a is oscillated and displaced rearward by being pushed by the introduction surface 41e moving backward, and allows the decorative plate 21 to enter. The introduction side portion 65e moves up so as to slide on the slope of the introduction surface 41e. When the decorative plate 21 is further tilted so that the lower end corner portion of the introduction side portion 65e moves to the upper end of the introduction surface 41e and the engagement is released, the arm portion 65a elastically deformed rearward is moved forward by the elastic force. The locking side portion 65f is displaced so as to slide down the locking surface 41f, and the locking side portion 65f and the locking surface 41f are engaged. Further, at this time, the backing plate receiving portion 41a of the decorative plate comes into contact with the backing plate portion 11a, and the game board 20 is temporarily fixed to the storage frame 10 in the storage posture.
[0054]
In this temporarily fixed state, the locking side portion 65f of the temporary fixing metal fitting 65 is engaged with the locking surface 41f of the decorative plate 21 so as to hold the decorative plate 21 between the contact plate portion 11a. Even if the operator releases the pressing force that presses the decorative plate 21 backward, the game board 20 is maintained in the housed posture (temporary fasteners indicated by two-dot chain lines in FIGS. 8B and 6). 65). For this reason, the game board 20 does not fall out of the storage frame 10 or slide out.
[0055]
After the game board 20 is temporarily fixed in this way, the operator rotates the operation bolt 61 clockwise from the front of the front frame 2. When the operation bolt 61 is rotated, the tip end portion of the temporary fixing metal fitting 65 moves upward along an arc locus, and along with this, the tip end portion of the fixing metal fitting 63 moves down along an arc locus. The curved surface area of the pressing portion 63c that is gently bent forward on the front end side of the lever portion 63 smoothly engages with the front surface of the decorative plate 21. When the operation bolt 61 is further rotated, the engagement between the locking side portion 65f of the temporary fixing metal fitting and the locking surface 41f of the decorative plate is released, while the curved surface region on the tip side of the pressing portion 63c moves downward. Accordingly, the flat area on the base end side of the pressing portion 63c engages with the front surface of the decorative board 21 and presses the decorative board 21 backward.
[0056]
Then, when the lever part 63a of the fixing bracket is swung to the fixing position extending vertically downward, the temporary fixing metal fitting 65 is horizontally stored in the upper frame part 11, and the pressing part 63c of the fixing metal part moves the decorative plate 21 backward. The game board 20 is fixedly held in the housing frame 10 so that the decorative board 21 is sandwiched between it and the back plate part 41a (see FIGS. 8A and 6).
[0057]
Thus, in a state where the game board 20 is fixedly held to the storage frame 10, the contact plate portion 11a is received by the contact plate receiving portion 41a, and the rear end surface of the storage frame 10 and the back surface of the decorative plate 21 are aligned in the front-rear direction. A flat back surface is formed. For this reason, the flat surface is formed in the back surface side of the storage frame 10, and the structure which improved the consistency with the back set board 30 closed behind this is implement | achieved. Further, the contact plate portion 11 a is formed so as to protrude from the inner surface of the upper frame portion 11 toward the inside of the housing frame 10, and the back surface side of the decorative plate 21 is counterbored to form the contact plate receiving portion 41 a. Therefore, the thickness dimension of the front frame 2 including the housing frame 10 can be configured to be thin.
[0058]
On the other hand, when removing the game board 20 fixedly held in the housing frame 10, the glass door 5 is opened, and the operation bolt 61 is turned counterclockwise from the front of the front frame 2 using a hexagon wrench or the like. .
[0059]
When the operation bolt 61 is rotated counterclockwise, the pressing portion 63c of the fixing bracket 63 moves upward along an arc trajectory, and accordingly, the tip end portion of the temporary fixing bracket 65 descends along an arc trajectory. First, the rear corner portion of the locking side portion 65f of the temporary fixing metal fitting is engaged with the locking surface 41f of the decorative plate. When the operation bolt 61 is further rotated, the locking side portion 65f of the temporary fixing metal fitting and the locking surface 41f of the decorative plate are engaged by surface contact, while the pressing portion 63c is moved upward to contact the fixing metal fitting 63. The engagement with the decorative board 21 is released.
[0060]
Then, when the fixing bracket 63 is swung to the open position where it is horizontally stored in the upper frame portion 11, the lever portion 65a of the temporary fixing bracket is disposed at the temporary fixing position extending vertically downward. The stop side portion 65f engages with the engaging surface 41f of the decorative plate to temporarily fix and support the game board 20 on the housing frame 10 (see FIG. 8B). For this reason, even if the operator does not press the game board 20 during the opening operation, the game board 20 does not fall down or slide out of the housing frame 10, and the fixing bracket 63 is opened. The game board 20 is held in the temporarily fixed posture temporarily fixed to the storage frame 10 even when it is positioned at the position.
[0061]
Next, from this temporarily fixed posture, for example, a finger is applied to a game nail or an outer rail above the game board, and the decorative board 21 is pulled out forward. At this time, the game board 20 tends to tilt forward with the locking portion 51 as the center, since the lower end portion of the front surface of the decorative plate 21 is locked by the locking fitting 51. For this reason, the locking side portion 65f engaged with the locking surface 41f is pulled forward, and the arm portion 65a elastically swings and deforms, allowing the game board to tilt in the forward tilting direction. The stop side portion 65f moves up so as to slide on the locking surface 41f.
[0062]
Then, when the lower end corner portion of the locking side portion 65f moves to the upper end of the locking surface 41f and the engagement is released, the arm portion 65a that has elastically deformed forward is self-reset backward by the elastic force, It returns to the state before temporary fixing shown in FIG. In this state, the lower end of the decorative board 21 is in a temporary support posture in which it is elastically supported by the locking metal fitting 51, and even if the front side of the game board 20 is not supported, the game board does not fall forward. Therefore, the operator can remove the game board 20 by grasping an appropriate position for carrying out the game board 20 with both hands and pulling the decorative plate 21 obliquely upward.
[0063]
Thus, in the pachinko machine PM of this configuration, when the game board 20 is locked to the locking mechanism 50, the game board 20 is locked in the temporary support posture biased in the accommodation direction, and the game board When the 20 is accommodated in the accommodation frame 10, the game board is maintained in the accommodation posture even in a state where it is temporarily fixed to the accommodation posture by the temporary support fixing mechanism 60 and the fixing by the fixing bracket 63 is released. Therefore, at the time of attaching / detaching the game board, even if the game board 20 accommodated in the accommodation frame 10 is not supported, the game board 20 does not fall down or slide out, so that the game board is dropped. Alternatively, it is possible to prevent the connector cable connected to the back side of the game board from being damaged, and even an unskilled person can easily and safely attach and detach the game board.
[0064]
In the above, the introduction surface 41e and the locking surface 41f are formed on the upper edge portion of the decorative board 21, and the leading edge portion of the temporary fixing metal fitting 65 is bent and formed in multiple stages to introduce the introduction side portion 65e and the locking side portion 65f. In the embodiment, the locking side portion 65f is relatively displaced so as to get over the upper side portion 41b, and is engaged with the locking surface 41f to temporarily support the game board 20, but the upper edge of the decorative board 21 is illustrated. It may be configured without providing the introduction surface 41e, the locking surface 41f, the temporary fitting receiving groove 41c and the like as described above. That is, the upper edge engaging portion 41 of the decorative plate 21 is provided with only the contact plate receiving portion 41a and the upper side portion 41b to form the upper edge flat, and at the tip as indicated by a two-dot chain line in FIG. The temporary fixing metal fitting 65 'formed with the curved locking portion is engaged and supported by the operation bolt 61 in the same manner as described above, and the engaging portion and the upper side portion are frictionally engaged using the elastic force of the temporary fixing metal fitting 65'. It is also possible to configure the game board 20 to be temporarily fixed and supported.
[0065]
In addition, in the embodiment, the ease of attaching and detaching the game board, the stabilization of the temporary support posture of the game board 20 by the locking mechanism 50, the simplification of the mechanism configuration disposed in the lower frame portion 12, and the upper and lower sides of the decorative board 21 From the viewpoint of preventing the side from rising, an example in which the locking mechanism 50 is provided in the lower frame portion 12 of the storage frame 10 and the temporary support fixing mechanism 60 is provided in the upper frame portion 11 has been described. If the positional relationship is disposed in the frame portion where the stopping mechanism 50 and the temporary support fixing mechanism 60 are opposed to each other, the positional relationship can be changed as appropriate. It is also possible to arrange it so as to face the left and right frame portions.
[0066]
Furthermore, in the embodiment, the fixing metal fitting 63 and the temporary fixing metal fitting 65 are engaged and connected to the operation bolt 61 at a relative angle of 90 degrees, and the operation bolt 61 is rotated using a wrench so that both the metal fittings are integrated. An example in which the temporary fitting 65 is disposed at the temporary fixing position at the opening position of the fixing bracket 63 by oscillating and displacing is illustrated. However, the fixing bracket and the temporary fixing bracket are integrally displaced to release the fixing bracket. What is necessary is just to comprise so that a temporary attachment metal fitting may become a temporary attachment position in a position, and it can comprise by changing suitably the relative angle of both metal fittings, an operation form, a displacement form, etc. For example, a fixing bracket formed with a locking side part protruding downward is disposed on the upper frame part so as to be slidable in the left-right direction, while an open groove that can be engaged with and disengaged from the locking side part on the upper edge of the decorative plate The engaging side and the front surface of the decorative plate are engaged to fix the game board at the engaging position, and the locking side and the opening groove are aligned at the open position. The panel is configured to be able to pass back and forth, and the same temporary fixing bracket as described above is fixed to the fixing bracket, and is slidably disposed along with the fixing bracket. Even if it is a form which forms an edge engaging part, the same effect | action and effect can be acquired.
