[Problems to be solved by the invention]
Here, the back mechanism frame is provided with a game ball processing mechanism, a prize ball mechanism, and the like as described above, and when the constituent members of the fixing mechanism are arranged so as to protrude rearward from the back surface of the game board. Therefore, there is a problem that the structure of the back mechanism frame is complicated. In particular, a tank member for storing game balls and an alignment rod member (also referred to as a tank rail) for guiding the game balls supplied from the tank member to the ball payout device are disposed on the upper part of the back mechanism frame. If the fixing mechanism is protruded and disposed in this region, not only the configuration of the back mechanism frame is complicated, but also the smooth flow of the game ball may be hindered to cause a functional problem. For this reason, in conventional gaming machines, a game board fixing mechanism is generally provided on the left and right frame portions of the housing frame. For example, two metal fittings are provided on the left and right frame portions to move the game board (decorative board) forward. And fixedly held in a storage frame formed in a frame shape. However, in such a conventional fixing device, the center of the upper side of the gaming board tends to be insufficiently fixed, and in some gaming machines, the center of the upper side of the gaming board is used in an unstable state where it is lifted from the housing frame. There was a problem that some were found.
[0007]
The present invention has been made in view of such problems, and does not complicate the configuration of the back mechanism frame or the like or prevent the game ball from flowing down, and stably and securely fix the game board. It is an object of the present invention to provide a possible game board fixing device.

Therefore, even if the operator does not hold the game board, the game board does not tilt or slide out, and the board can be exchanged easily and safely even if it is not a skilled worker.
  Further, in a state where the game board is housed and held in the housing space and fixed and held by the temporary support and fixing mechanism, the temporary support and fixing mechanism is positioned on the front side from the rear surface of the game board, and the back mechanism board is used as the frame member and the game. It is configured so that it can be placed over the back of the board.Therefore, it is possible to provide a fixing device that does not complicate the configuration of the back mechanism frame or the like disposed behind the game board or prevent the game ball from flowing down.
[0010]
The “frame member” refers to a member that detachably accommodates a game board and arranges the game area so as to face the glass door. For example, the accommodation frame that accommodates the game board is on the back side of the front frame. This means a front frame in a case (game machine with front frame front attachment / detachment), a back mechanism frame in a case in which a storage frame is provided on the back side of a back mechanism frame (game machine with back mechanism frame rear attachment / detachment), and the like. . The “accommodating posture” refers to an attitude in which the game board is positioned inside the frame member, and a pressing force is applied in the process of fixing and holding the game board by the fixing means from the stored attitude in which the game board is positioned inside the frame member. This is a concept including a posture before displacement in a case where the game board is displaced to a certain extent due to the above.

[0022]
The housing frame 10 includes an upper frame portion 11, a lower frame portion 12, a right frame portion 13 and a left frame portion 14 which are formed so as to surround the game board 20. Frame-shaped front surface support portions 11a, 12a, 13a, and 14a that support the front surface of the decorative plate 21 are formed in front of each frame portion, and the front surface of the front frame 2 is formed on each frame portion except for the upper frame portion 11. Wall-shaped end surface support portions 12b, 13b, and 14b are formed that extend rearward from the side and surround the lower edge and the left and right side edges of the decorative plate 21 from three directions. The distance between the inner surfaces of the left and right end face support portions 13b and 14b is formed to be about 1 to 2 mm larger than the width dimension of the game board 20, and the game board 20 is received from the back side of the front frame 2 to receive the three end face support parts. The game board 20 is accommodated in the housing frame 10 so that the decorative board 21 is sandwiched between the front support portion by a locking mechanism 50, a temporary fixing fixing mechanism 60, and a fixing mechanism 80 described later. Hold fixed.
[0023]
In the housing frame 10 configured as described above, locking mechanisms 50 are disposed at two positions on the left and right sides of the lower frame portion 12. A side sectional view of the vicinity of the locking mechanism 50 viewed in the direction of arrows IV-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 these drawings.
[0024]
The locking mechanism 50 is mainly configured by a locking metal fitting 51 that is fixed to the game assisting board 15 and protrudes above the rear portion of the end surface support portion 12b. The locking metal 51 extends in the vertical direction and has a fixed side 51a in which a mounting hole for inserting the screw 58 is formed, a contact side 51b extending horizontally by bending the upper part of the fixed side 51a at a right angle, and a contact side The rear part is formed of a locking side part 51c that is bent upward at a right angle and extends upward, and is formed in a crank shape in a side view.
[0025]
On the other hand, the gaming auxiliary board 15 to which the locking metal fitting 51 is attached is formed with a cylindrical boss 12c that is positioned below the end face support portion 12b and supports the fixed side portion 51a, and receives a screw 58 at the center thereof. A screw receiving portion is formed. The shape dimensions of the side portions 51a, 51b, 51c in the locking fitting 51 are set based on the relative relationship between the lower frame portion 12 and the boss 12c, and the locking fitting 51 is attached to the boss 12c as shown in FIG. The thickness of the decorative plate 21 is between the upper surface of the contact side portion 51b and the lower surface of the end surface support portion 12b, and the front surface of the locking side portion 51c protruding upward is between the front surface support portion 12a. Is set to face each other at the same (or slightly smaller) interval.
[0026]
Further, the upper part of the locking side 51c is gently bent backward so that the lower end of the decorative board 21 is smoothly received and guided, and the decorative board 21 is not damaged such as scratches. It has become. 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]
The locking metal fitting 51 is supported so that the upper surface of the contact side 51b is in contact with the lower surface of the end surface support 12b and the front surface of the fixed side 51a is in contact with the end surface of the boss 12c. The screw 58 is screwed into the screw receiving portion of the boss 12c and tightened from behind, so that the game auxiliary board 15 is attached. When the locking metal fitting 51 is thus attached, the locking side portion 51c protrudes upward so as to face the front surface support portion behind the end surface support portion 12b, and the front surface of the locking side portion 51c and the support surface of the front surface support portion 12a. A housing space having a dimension in the front-rear direction substantially the same as the thickness of the decorative board 21 is formed between the two.
[0028]
The operation of mounting the game board 20 on the locking mechanism 50 configured as described above is performed with the front frame 2 opened to the outer frame 1 and the back set board 30 opened to the front frame 2. , From the back side of the front frame 2. The operator holds the left and right side edges of the decorative board 21 from behind the game board 20 to support the game board 20 in a slightly tilted posture, and accommodates the lower end of the decorative board 21 from above the locking side 51c. Insert into the frame 10 at an angle.
[0029]
Here, the height of the locking side portion 51 c is set to be lower than the upper end of the front surface support portion 12 a in the lower frame portion 12. For this reason, when the decorative board 21 is inserted diagonally into the housing frame 10 along the left and right end face support portions 13b, 14b, the lower end portion on the front side of the decorative board 21 is first engaged with the front support section. By being guided and slidingly moving the decorative plate 21 as it is, it is possible to engage the two locking side portions 51 c at the right and left positions with the appropriate position of the decorative plate 21. Since the upper end portion of the locking side portion 51c is gently bent toward the front, the decorative plate 21 slid downward is guided smoothly toward the end surface support portion 12b at the lower end portion. The toe part 51c is elastically deformed rearward to receive the decorative board 21 in an inclined posture. Thereby, the game board 20 is elastically supported on the end surface support portion 12b in a backward inclined posture.
[0030]
In addition, the lower end corner portion on the front side of the decorative board 21 is cut obliquely to form a flank 42e, so that the game board 20 can be easily inserted and removed in a tilted posture, and an excessive stress is applied to the locking bracket 51. Is not generated. Further, the locking metal 51 is formed with an abutting side portion 51b so as to be abutted and supported on the lower surface of the end surface support portion 12b. For this reason, when a force that tilts the locking side 51c backward acts and elastically deforms, the contact side 51b that swings relatively upward transmits this force to the lower frame 12 for support. And the force acting on the fixed side 51a is reduced. Accordingly, an excessive bending moment or pulling force is hardly applied to the boss 12c via the screw 58, and the boss 12c is not easily broken or the screw receiving portion is not easily damaged. Further, by bending and forming the locking metal fitting 51 and fixing it to the game auxiliary board, it is possible to increase the length of the region that can be elastically deformed compared to a configuration in which the locking metal fitting is directly attached to the end surface support portion, A locking mechanism that is difficult to be plastically deformed can be configured in a small size.
[0031]
In the embodiment, the locking side 51c of the locking bracket is bent at a right angle with respect to the abutting side 51b, and the front support 12a is spaced substantially the same as the thickness of the decorative plate 21. Although the form which protrudes vertically upward was illustrated, the latching mechanism 50 is not limited to the form which concerns, What is necessary is just what can latch the lower end part of the decorative board 21. FIG. For example, in the case where the same locking metal fitting as in the embodiment is provided, there is a space slightly larger than the plate thickness of the decorative plate 21 between the lower side of the locking side portion and the front support portion 12a. Then, the locking side 51c is positioned at a right angle with respect to the contact side 51b so that the gap between the upper side of the locking side and the front support 12a is slightly smaller than the thickness of the decorative plate 21. Alternatively, it may be bent at a small angle and protrude in a slightly forward tilted posture. In this type of locking mechanism, even if there is some variation in the thickness of the decorative plate 21, the locking bracket elastically absorbs, creating a gap between the decorative plate and an excessive load on the boss 12c. Does not act.
[0032]

It is composed of a clamp lever 65e or the like whose upper edge is bent backward and an operation side is formed, and a metal material such as a cold-rolled steel sheet having a thickness of about 2 to 3 mm is formed using a known processing means such as press forming. It is formed into the shape shown in the figure, and after the collar 65k is crimped and crimped, it is formed by performing a required surface treatment as required.
[0038]
The temporary fixing metal fitting 63 and the fixing metal fitting 65 thus formed are integrally joined by a joining means such as electric resistance welding, pressure welding, brazing or the like in a state where the relative position is positioned by a jig. That is, the engagement hole of the ring portion 63a in the temporary fixing metal fitting 63 and the shaft center of the collar 65k in the fixing metal fitting 65 are aligned, and the engagement portion (the locking side portion 63c or the like) is centered on the shaft center in the rear view. In a state where the extending direction of the clamp lever 65e and the extending direction of the clamp lever 65e are arranged in a straight line, and are positioned so that the extending direction of the engaging portion and the extending direction of the pressing portion 65c are orthogonal to each other. To join.
[0039]
On the other hand, a columnar fixing boss 11c is erected in the upper center of the upper frame portion 11 so as to extend rearward from the front frame 2, and a column fixing hole for receiving and fixing the knurled portion of the column 61 at the center thereof. Is formed. The rear end position (seat surface formation position) of the fixed boss 11c is set in front of the support surface of the front support portion 11a in the upper frame portion 11, and the support 61 is press-fitted and fixed to the fixed boss 11c. When the is assembled, the constituent members of the temporary support fixing mechanism such as the cap nut 67 and the temporary fixing metal fitting 63 are configured not to protrude rearward from the back surface of the decorative plate 21. The rear end surface of the upper frame portion 11 is formed with a lever accommodating portion 11e that receives and accommodates the clamp lever 65e when the fixing bracket 65 is rotated to the fixed position.
[0040]
The temporary support fixing mechanism 60 is integrated with the support shaft portion protruding rearward by driving the knurled portion on the front end side of the support post 61 into the support fixing hole of the fixing boss 11c from the rear surface side of the front frame 2 and press-fitting and fixing. The upper fixing hole 63 and the fixing bracket 65 are inserted through the engagement holes and the collar 65k, and the coil spring 66 is engaged and supported from the rear, and the cap nut 67 is screwed into the male screw portion and tightened to tighten the upper frame portion 11. Attached to. Thereby, the temporary fixing metal fitting 63 and the fixing metal fitting 65 are attached so as to be swingable integrally around the axis of the column 61 while being urged forward by the coil spring 66 with a predetermined urging force.
[0041]
When the temporary fixing metal fitting 63 and the fixing metal fitting 65 are thus attached, the clamp lever 65e is rotated from the back side of the front frame 2 so that the pressing portion of the fixing metal fitting 65 protrudes downward and is positioned in the accommodated posture. The plate 21 can be oscillated and displaced between a fixed position (state shown in FIG. 10) and an open position (state shown in FIG. 9) where the plate 21 is retracted and released from engagement with the decorative board 21. Further, when the fixing metal fitting 65 is located at the open position, the engaging portion of the temporary attachment metal 63 is disposed at the temporary attachment position protruding downward, and the game board 20 is detachably accommodated in the accommodation frame 10, and The game board 20 is temporarily fixed and supported in the accommodated posture by engaging with the back side of the accommodated decorative board 21.
[0042]
On the other hand, the central portion of the upper edge of the decorative plate 21 is cut into a concave shape in accordance with the arrangement position of the temporary support fixing mechanism 60, and a mechanism accommodating portion 40 for accommodating the main part of the temporary support fixing mechanism 60 is formed. A mechanism engaging portion 41 is formed on the bottom of the mechanism housing portion 40 so as to be detachably engaged with the temporary fixing metal fitting 63 and the fixing metal fitting 65. The mechanism engaging portion 41 includes a supported surface 41a that is supported in contact with the front surface support portion 11a of the upper frame portion, a guide surface 41b that extends horizontally in the front-rear direction, and a back surface side of the decorative plate 21 that has been counterbored so that the back surface of the decorative plate The locking surface 41c positioned further forward, the corner where the supported surface 41a and the guide surface 41b cross each other is cut obliquely and formed into an inclined surface 41e, the guide surface 41b and the locking surface 41c. It is composed of a lead-out surface 41f formed in the shape of a slope between them.
[0043]
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. It is formed so as to come into contact with 63e and the introduction side 63e can ride on the introduction surface 41e. The locking surface 41c is formed on the basis of the relative relationship between the position where the engagement portion of the temporary fixing metal is disposed and the position where the pressing portion 65c of the fixing metal is disposed. The back surface of the decorative plate 21 is formed by counterboring the back surface of the decorative plate 21 at a predetermined depth so that the rear end portion of the metal fitting 65 does not protrude rearward from the back surface of the decorative plate 21.
[0044]
Paradoxically, the formation position of the locking edge portion 63c of the temporary fitting and the formation position of the pressing portion 65c of the fixed fitting are set with reference to the formation position of the locking surface 41c, and When the disposition position is set to be slightly ahead of the disposition position of the locking surface 41c positioned in the storage posture, and the pressing portion 65c is engaged with the locking surface 41c, the pressing portion 65c is It is set so that it rides on the locking surface 41c and moves slightly backward to press the decorative plate forward by the elastic force of the coil spring 66. Further, the disposition position of the front surface of the locking side portion 63c is set somewhat behind the disposition position of the locking surface 41c positioned in the accommodation posture, and the temporary fixing metal fitting 63 is fixed to the temporary fixing position (fixing metal fitting 65). Is set to be surely engaged with the locking surface 41c when the game board 20 is accommodated in the open position.
[0045]
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.
[0046]
The operator opens the front frame 2 with respect to the outer frame 1 and opens the back set board 30 with respect to the front frame 2, and moves the clamp lever 65 e counterclockwise from the back side of the front frame 2. By rotating, the pressing portion 65c of the fixing bracket is positioned at the open position where the pressing portion 65c is swung upward. At this time, the swing arm portion 63b of the temporary fixing metal fitting is disposed downward, and the engagement portions (the locking side portion 63c, the intermediate side portion 63d, and the introduction side portion 63e) at the tip of the arm portion are provided at the temporary fixing position. (See FIG. 9). Note that the clamp lever 65e is also rotated counterclockwise for the left and right fixing mechanisms 80, which will be described later, and the pressing portion 65c of the fixing bracket is swung away from the frame portion.
[0047]
Then, the lower end portion of the decorative plate 21 is inserted into the housing frame 10 obliquely by using the locking mechanism 50 described above and engaged with the locking fitting 51, and the game board 20 is tilted downward and the lower frame portion 11. Elastically supported on top. In this state, when the operator weakens the force in the backward tilt direction, the upper part of the game board 20 is swung forward by the elastic force of the locking bracket 51, and the decorative board is added as indicated by a two-dot chain line in FIG. 21 is supported in a temporary support posture in which the introduction surface 41e of the mechanism engaging portion 41 formed on the upper portion of the member 21 is in contact with the introduction side portion 63e of the temporary fixing metal fitting 63.
[0048]
When the operator presses the upper portion of the game board 20 forward from this temporary support posture, the introduction side portion 63e is moved upward so as to slide on the introduction surface 41e by being guided by the introduction surface 41e moving forward, and the swing arm The part 63b is swung upward to allow the decorative plate 21 to enter. When the introduction side 63e reaches the upper end of the introduction surface 41e, the intermediate side 63d is engaged with the guide surface 41b, and the decorative plate 21 is received so as to slide on the guide surface 41b moving forward. Then, when the locking surface 41c is moved to the accommodation position aligned with the front end surface of the locking side portion 63c and the engagement between the lead-out surface 41f and the intermediate side portion 63d is released, the rocking that has been elastically deformed upward is released. The moving arm 63b self-returns downward due to the elastic force, the locking side 63c is displaced so as to slide down the locking surface 41c, and the locking side 63c and the locking surface 41c are engaged. At this time, the supported surface 41a of the decorative plate comes into contact with the front support portion 11a of the upper frame portion, and the game board 20 is temporarily fixed to the storage frame 10 in the storage posture.
[0049]
In this temporarily fixed state, the locking side 63c of the temporary fixing metal 63 is engaged with the locking surface 41c of the decorative plate 21 so as to hold the decorative plate 21 between the front support portion 11a. Even if the operator releases the pressing force that presses the decorative plate 21 forward, the game board 20 is maintained in the housed posture (see FIGS. 11 and 9). For this reason, the game board 20 does not fall or slide out of the storage frame 10.
[0050]
After the game board 20 is temporarily fixed in this manner, the operator rotates the clamp lever 65e clockwise. When the clamp lever 65e is rotated, the engaging portions (the locking side portion 63c, the intermediate side portion 63d, and the introduction side portion 63e) of the temporary fixing metal 63 move upward along an arc locus and the fixing metal 65 is pressed. The portion 65c moves downward along an arc trajectory, and first, a curved region that is gently bent backward on the distal end side of the pressing portion 65c smoothly engages with the locking surface 41c. When the clamp lever 65e is further rotated, the engagement between the engagement side portion 63c of the temporary attachment fitting and the engagement surface 41c is released, while the curved region on the distal end side of the pressing portion is moved downward. The flat region on the base end side of the pressing portion is engaged so as to run on the locking surface 41 c, and the fixing metal fitting 65 (and the temporary fixing metal fitting 63) moves slightly rearward along the support 61 while compressing and deforming the coil spring 66. Then, the decorative board 21 is pressed forward with an elastic force corresponding to the amount of movement.
[0051]
When the clamp lever 65e of the fixing bracket is accommodated in the clamp lever accommodating portion 11e and rotated to the fixing position where the lever portion extends horizontally, the temporary fixing bracket 63 is horizontally stored in the mechanism accommodating portion 40, and the fixing bracket is fixed. The pressing portion 65c presses the decorative plate 21 forward by the elastic force of the coil spring 66, sandwiches the decorative plate 21 with the front support portion 11a, and fixes and holds the game board 20 in the housing frame 10 (FIG. 6, (See FIGS. 8 and 10).
[0052]
In the state where the game board 20 is fixed and held in the housing frame 10 in this way, almost the entire temporary support and fixing mechanism 60 is accommodated in the mechanism accommodating portion 40 formed on the decorative board 21 as shown in FIG. 6 and 8, the entire temporary support mechanism 60 including components such as the temporary fixing metal fitting 63, the fixing metal fitting 65, and the cap nut 67 is disposed in front of the back surface of the decorative plate 21 that is fixedly held. For this reason, the configuration of the back set board 30 closed behind the housing frame 10, particularly the configuration around the tank member 35 disposed immediately after the present mechanism, is complicated, or the flow of game balls flowing down is hindered. Therefore, a configuration that can stably and securely hold the upper side of the decorative board is realized.
[0053]
On the other hand, when removing the game board 20 fixedly held in the storage frame 10, the clamp lever 65e is turned counterclockwise from the rear of the front frame.
[0054]
When the clamp lever 65e is rotated counterclockwise, the pressing portion 65c of the fixing bracket 65 moves upward along an arc trajectory, and the engaging portion of the temporary fixing bracket 63 along the arc trajectory accordingly. First, the locking side 63c of the temporary fitting is moved so as to be partially behind the locking surface 41c of the decorative plate. When the clamp lever 65e is further rotated, the substantially entire surface of the locking side portion 63c moves to the rear of the locking surface 41c, while the pressing portion 65c moves upward to engage the curved surface area with the locking surface 41c. The mating is gradually released, and the fixing metal 65 and the temporary fixing metal 63 gradually move forward until the ring portion 63a of the temporary fixing metal 63 comes into contact with the seating surface of the fixed boss 11c.
[0055]
When the clamp lever 65e is swung to the open position facing vertically upward, the pressing portion 65c is accommodated horizontally in the mechanism accommodating portion 40, and the engaging portion of the temporary fixing metal fitting 63 extends temporarily downward. The locking side portion 63c of the temporary fixing metal fitting is engaged with the locking surface 41 and temporarily supports the game board 20 to the housing frame 10 (see FIGS. 9 and 11). 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 from the housing frame 10, and the fixing bracket 65 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.
[0056]
Next, from this temporarily fixed posture, for example, a decorative ball 21 is attached to the back side of the decorative plate 21 and a finger is placed on the image control device case (both not shown) to pull the decorative plate 21 backward. At this time, the game board 20 tends to tilt backward with the locking portion 51 as the center because the lower end portion of the front surface of the decorative plate 21 is locked by the locking bracket 51. For this reason, the locking side portion 63c engaged with the locking surface 41c is pulled rearward, and the distal end side of the arm portion swings upward about the proximal end side of the swinging arm portion 63b.
[0057]
When the lower end corner portion of the locking side portion 63 exceeds the upper end of the locking surface 41c and reaches the lead-out surface 41f, the lower end corner portion of the locking side portion 61c is guided by the inclined lead-out surface 41f and shakes. A state before provisional fixing indicated by a two-dot chain line in FIG. 11, reaching the guide surface 41b so as to slide while swinging the moving arm 63b upward, and passing through the guide surface 41b and the introduction surface 41e. become. In this state, the lower end portion of the decorative board 21 is in a temporary support posture in which it is elastically supported by the fastener 51, and the game board does not fall down even if the back side of the game board 20 is not supported. 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.
[0058]
Thus, in the pachinko machine PM game 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 When the board 20 is housed in the housing frame 10, the game board is maintained in the housed position even when the board 20 is temporarily fixed to the housed position by the temporary support fixing mechanism 60 and the fixing by the fixing bracket 65 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.
[0059]
In the embodiment, the upper and lower sides of the decorative board 21 are prevented from being lifted, the game board is easily attached and detached, the temporary support posture of the game board 20 by the locking mechanism 50 is stabilized, and the lower frame 12 is provided. From the viewpoint of simplification of the mechanism configuration and the like, 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 shown. The positional relationship between the locking mechanism 50 and the temporary support fixing mechanism 60 can be appropriately changed as long as the positional relationship is provided in the frame portion facing each other. Or it is also possible to arrange it so as to face the left and right frame portions.
[0060]
In the embodiment, the direction in which the pressing portion of the fixing bracket 65 extends and the direction in which the engaging portion of the temporary fixing bracket 63 extends are orthogonal to each other, and these are supported by the support 61 so as to be able to rotate and swing. By exercising the clamp lever 65e formed on 65, both the metal fittings are integrally swung and displaced, and the temporary fixing metal fitting 63 is disposed at the temporary fixing position when the fixing metal fitting 65 is opened. However, it is sufficient if the fixing bracket and the temporary fixing bracket are integrally displaced so that the temporary fixing bracket is in the temporary fixing position at the opening position of the fixing bracket. The operation mode, the displacement mode, and the like can be appropriately changed. For example, a fixing bracket formed with a locking side part protruding downward is arranged on the upper frame part so as to be slidable in the left-right direction. In the engagement position, the locking side portion and the locking surface of the decorative plate engage with each other to fix the game board, and in the open position, the locking side portion and the open groove align to match the game. 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 arranged with the fixing bracket, and the same mechanism as described above on the decorative plate Even if it is a form which forms an engaging part, the same effect | action and effect can be acquired.
[0061]
Next, the fixing mechanism 80 disposed in the left and right frame portions 13 and 14 in the housing frame 10 will be described with reference to FIGS. 12 and 13. The fixing mechanism 80 is configured by using the same members as the temporary support fixing mechanism 60 described above except for the temporary fixing metal fitting 63, and the right and left fixing mechanisms are configured to be axially symmetric about the column 61. ing. Therefore, in the following, the fixing mechanism 80 disposed in the right frame portion 13 will be described by way of example, and redundant description of the fixing mechanism 80 disposed in the left frame portion 14 will be omitted. Here, FIG. 12 is a cross-sectional view taken along arrow XII-XII in FIG. 3, and is a plan cross-sectional view of the fixing mechanism 80 in a state where the game board 20 is stored in the storage frame 10 and the decorative board 21 is fixed. 13 is a rear view of the periphery of the fixing mechanism 80 as viewed in the direction of arrow XIII in FIG.
[0062]
The fixing mechanism 80 has a support 61 fixed to the right frame 13 from the back side of the front frame 2, a fixing metal 65 supported by the support 61 so as to be swingable and displaceable, a temporary fixing metal 63 and the fixing metal 65 forward. Coil spring 66 to be urged, and a cap nut with a seat which is screwed and fastened to a male screw portion formed at the rear end portion of the column 61 to compress the coil spring 66 and urge the temporary fixing metal 63 and the fixing metal 65 forward. 67, etc., except that the temporary fixing metal fitting 63 is not used, and is configured in the same manner using the same member as the temporary support fixing mechanism 60 described above.
[0063]
Further, the right frame portion 13 is formed with a front surface support portion 13a for supporting the front surface of the decorative board 21, and a fixed boss 13c is formed extending from the front of the front frame to the rear, and the support 61 is formed at the center thereof. A column fixing hole for receiving and fixing the knurled portion is formed. The rear end position (seat surface forming position) of the fixed boss 13c is such that when the support 61 is press-fitted and fixed to the fixed boss 13c and the fixing mechanism 80 is assembled, the front position of the pressing portion 65c of the fixing bracket 65 is in the accommodated posture. It is set so as to be somewhat forward of the position of the rear surface of the decorative plate 21 that is positioned, and when the pressing portion 65c is engaged with the decorative plate 21, the pressing portion 65c rides on the decorative plate 21 and is slightly It is set to move backward and press the decorative plate forward by the elastic force of the coil spring 66.
[0064]
On the other hand, the frame set front end of the base frame body 31 is partly cut off in accordance with the arrangement position of the pressing portion 65c in the fixed position on the back set board 30 closed behind the decorative plate 21, and the pressing portion 65c. A receiving notch 31c is formed to receive the. The decorative plate 21 has an arm receiving portion 43a formed by cutting the side end surface of the decorative plate 21 into a U shape in accordance with the swinging trajectory of the clamp arm 65b. Sometimes, the clamp arm 65b does not come into contact with the side end surface of the decorative plate 21.
[0065]
The temporary support fixing mechanism 60 drives the knurl portion on the front end side of the support 61 from the back side of the front frame 2 into the support fixing hole of the fixing boss 13c to press fit and fix the collar of the fixing bracket 65 on the support shaft protruding rearward. 65k is inserted, the coil spring 66 is engaged and supported from the rear, and the cap nut 67 is screwed into the male screw portion and tightened, whereby the fixing bracket 65 is urged forward by the coil spring 66 with a predetermined urging force. On the other hand, it is attached so as to be swingable integrally around the axis of the column 61.
[0066]
When the fixing bracket 65 is attached in this way, the decorative lever 21 positioned in the housing posture is fixed by projecting the pressing portion 65c inward of the housing frame by rotating the clamp lever 65e from the back side of the front frame 2. A fixing position (state indicated by a solid line in FIGS. 12 and 13), and an open position where the engagement with the decorative plate 21 is released by retracting outside the housing frame (indicated by a two-dot chain line in FIG. 13). Oscillating displacement to the state).
[0067]
The operation of the fixing mechanism 80 configured in this manner will be briefly described from the case where the game board 20 is fixed. The operator places the fixing bracket 65 in the open position so that the pressing portion 65c extends along the end surface support portion 13b. In the state where the game board 20 is temporarily fixed and supported in the accommodated posture using the locking mechanism 50 and the temporary support fixing mechanism 60 described above, the clamp lever 65e is put on with a finger to fix the bracket. 65 is rotated clockwise.
[0068]
When the clamp lever 65e is rotated, the clamp arm 65b enters the arm receiving portion 43a and the pressing portion 65c swings inward in the frame portion while drawing an arc trajectory. The curved region that is gently bent is smoothly engaged with the back surface of the decorative plate 21. When the clamp lever 65e is further rotated, the flat region on the base end side of the pressing portion is engaged so as to ride on the decorative plate 21, and moves slightly rearward along the support column 61 while compressing and deforming the coil spring 66. . When the clamp lever 65e of the fixing bracket is rotated to the fixing position extending vertically upward, the pressing portion 65c of the fixing bracket presses the decorative plate 21 forward by the elastic force of the coil spring 66, and the front support portion 13a. The decorative board 21 is sandwiched therebetween, and the game board 20 is fixedly held in the housing frame 10.
[0069]
In this way, the back set board 30 is closed from the back side of the front frame 2 on which the game board 20 is fixedly held. The base frame 31 is formed with a receiving notch 31c that receives the pressing portion 65c at the fixed position. Therefore, when the fixing bracket 65 is set at the fixed position and the game board 20 is accurately fixed and held, The front end surface of the frame 31 can be brought into contact with the back surface of the decorative plate 21 and closed. On the other hand, in an incompletely fixed state where the fixing bracket 65 is not completely rotated to the fixing position, the pressing portion 65c and the receiving notch portion 31c are not aligned with each other so that the back set board 30 cannot be completely closed. It has become. For this reason, an improper operation is prevented, and a fixing mechanism that can securely fix and hold the game board is configured.
[0070]
On the other hand, when removing the game board 20 fixedly held in the storage frame 10, the clamp lever 65e is turned counterclockwise from the rear of the front frame. When the clamp lever 65e is rotated, the pressing portion 65c of the fixing bracket moves upward along an arc trajectory, and the engagement between the curved surface area and the locking surface 41c is gradually released. Along with this, the fixture 65 urged by the coil spring 66 gradually moves forward to a position where it comes into contact with the seating surface of the fixed boss 13c. When the clamp lever 65e is swung to the open position facing leftward in the horizontal direction, the pressing portion 65c is arranged to extend vertically upward along the end surface support portion 13b and retracts outside the housing frame 10. . In this state, the game board 20 is temporarily fixed and supported by the temporary support and fixing mechanism 60 described above, and the game board 20 does not fall down or slide out of the housing frame 10.
[0071]
The game board fixing device configured as described above is provided with locking mechanisms 50 on the lower left and right sides of the game board 20 (decorative board 21), and is temporarily supported and fixed at the center of the upper side of the game board 20. The mechanism 60 is provided, and an isosceles triangle fixed form with respect to the lower side of the game board 20 is formed. In addition, the left and right side portions of the game board 20 are fixed in addition to the left and right fixing mechanisms 80, 80, and a pentagonal fixing form with the lower side as a reference is formed. Therefore, unlike the conventional fixing mechanism provided in the left and right frame parts, the game board does not float at the center part of the upper frame part and the lower frame part. The game board 20 is securely fixed to the housing frame by the fixed form to constitute a highly stable fixing mechanism.
[0072]
In the embodiment, the pressing portion 65c is engaged with the back surface of the decorative board 21 to fix and hold the game board. However, the back surface of the decorative board is counterbored similarly to the temporary support fixing mechanism 60 described above. Thus, the locking surface (41c) can be formed, and the pressing portion 65c, the cap nut 67, and the like can be configured not to protrude rearward from the back surface of the decorative plate 21 positioned in the housing posture. Further, in addition to the temporary support fixing mechanism 60 described above, the temporary fixing metal fitting 63 can be provided. In addition, the temporary support metal fittings can be attached to the right and left fixing mechanisms without providing the temporary fixing metal fittings in the upper frame fixing mechanism. It is good also as a structure which provides.
