For this reason, there is a considerable amount of difficulty in the above-mentioned work operations such as replacement and inspection / repair while the front frame side is open. For example, in a situation in which the entire open front frame side is likely to change from the open neutral position to any one, when work can be completed in a relatively short time or when one hand (mainly right hand) can be easily performed, The technician and manager do not have much trouble. However, when it takes a long time or when both hands work is required, the entire front frame side, which tends to fluctuate, becomes an obstacle in performing the work, which is not only bothersome but also painful to other players. there were.

The present invention has been proposed in order to preferably solve the above-mentioned problems, and the front frame assembled to the outer frame can be restrained and held at a required open position to eliminate fluctuations and the like, and a game board. It is an object of the present invention to provide a gaming machine capable of simplifying the work relating to the replacement of the machine and the inspection and repair of the back side constituent member, and the safety.

[0007]

As a technical means for overcoming the above-mentioned problems and suitably achieving the intended purpose, the present invention provides various kinds of games for the front side of the opening of the outer frame. In a model in which a front frame on which the constituent members are mounted is connected and supported by open / close connecting support means above and below the side edges so as to be openable and closable in an upright state, and at a required portion on the open / close connecting support means side of the outer frame and the front frame. An opening holding means for holding the front frame at a predetermined opening position is provided, and in this opening holding means, the movable locking member is supported by the outer frame or the front frame so as to be able to move up and down, and the end of the movable locking member is moved. The means for disengaging the engaging portion of the portion from the engaging portion formed on the frame on the opposite side can be engaged and disengaged.

[0008]

In the opened state of the front frame with respect to the outer frame, the movable locking member which can be moved up and down in the opening holding means is displaced in the locking direction to engage the locking portion with the engaging portion, whereby the entire front frame is predetermined. It is held in the fully open position. Also,

However, the support seat 56 has the same thickness as the upper and lower overlapping portions of the receiving seat 8 and the support seat 24 of both frames A and B.

The locking means D is of a composite type (generally referred to as a double lock) in which the locking of the front frame B and the locking of the glass door 31 of the window forming member 30 can be used together. .. That is, as shown schematically in FIGS.
A lock mechanism body 60 provided with a cylinder lock 61 that can be unlocked from the front side of the frame is installed on the back side of the right edge of the frame body 20. In summary, the locking mechanism on the front frame B side is mainly composed of this locking mechanism 60. In summary, the lifting operation rod 62 is always biased and held in the locking direction and is displaced in the unlocking direction by the lock plate 61a of the cylinder lock 61, and the vertical movement. It has hanging parts 63 which are supported at the ends and are connected to the elevating operation rods 62, respectively. Then, with respect to the displacement of locking and unlocking of the lifting operation rod 62, the upper and lower hooks 6
3 can be changed into an engaged state and a released state with respect to the receiving member 64 on the outer frame A side.

The receiving member 64 associated with the locking means D is fixed to the installation portion 65 formed above and below the inside of the right frame rod 3 of the outer frame A. That is, as shown in FIG. 11, each receiving member 64 has an attachment portion 64 b having a screw hole and a receiving portion 64 for the hanging member 63 with reference to the supporting portion 64 a.
and c are bent and formed in a series at right angles. On the other hand, as shown in the figure, each installation portion 65 has a pair of upper and lower support pieces 66 having a groove 67 and a boss portion 68 having a screw hole.
And the contact portion 69 located between the support pieces 66 are integrally formed. Then, each receiving member 64 is inserted and set in the concave groove 67 from the back side of the installation portion 65 and fixed by the minimum number of screws 70.

The open holding means E is composed of the two frames A,
According to the assembly conditions of B, for convenience, the 90 ° open position of the front frame B is regarded as a neutral position and is fully opened. Equipped. That is, as shown in FIGS. 8, 12, and 13, the support cylinder portion 71 formed in the lower left corner of the frame body 20.
Mainly includes a movable locking rod 73 that is vertically inserted into the hole 72 of the support cylinder portion 71, and an engagement hole 77 provided in the front plate portion 7 of the lower frame rod 4 of the outer frame A. The movable locking rod 73 is always urged downward by the spring 76 in the hole 72 so that the locking shaft 74 can be detachably fitted into the engaging hole 77. However, the movable locking rod 73 exemplifies a type in which a small-diameter support bar 75 is connected to the upper end of the locking shaft 74, and the hole 72
After being vertically inserted inside, a knob 78 also serving as a stopper is fixed to the upper end of the support bar 75, and the lifting operation can be easily performed by using the knob 78. The engagement hole 77 is illustrated as being penetrated at a required position in the lower support boss 51 that is appropriately separated from the support shaft 53, but may be a bottomed hole.

Another means for assembling the two frames A and B will be additionally described. First, as a means for connecting the front frame B to the outer frame A, as shown in FIGS. 4 to 6 and the like, the engaging support pieces 81 projecting from the upper, lower, left and right four positions on the front side of the frame body 20 are provided on the left and right side frames. The engaging surfaces 82 on the inner sides of the rods 2 and 3 are engaged or abutted, respectively. Further, as means for stabilizing the posture of the front frame B with respect to the outer frame A, as shown in FIG.
The pressing piece 83 protruding from the front end surface of the frame is pressed against the engaging seat 84 formed on the upper end surface of the frame body 20.

In the bachinko machine of this embodiment described above,
First, a manner of assembling (attaching / detaching) both frames A and B forming a frame will be described. That is, the upper and lower open / close connection support means C1,
Regarding C2, the lower frame is connected first, and then the upper frame is connected.
As shown in FIGS. 9 and 10, the bearing boss portion 54 is attached to the support boss portion 51 of the lower open connection supporting means C2 while being held at an appropriately high position in the opening direction of 90 degrees (orthogonal direction). The both boss portions 51 and 54 are connected by aligning the positions upward and inserting the shaft hole 55 into the support shaft 53. At this time, if the front frame B is slightly tilted by utilizing the fitting tolerance between the support shaft 53 and the shaft hole 55, the both 53, 55 are extremely easily fitted and inserted.

Next, the movable support shaft 45 of the above open connection support means C1 is once pulled by holding the knob 47, the bearing boss 43 is positioned below the support boss 41, and the knob 47 is released. As a result, the movable support shaft 45 causes the spring 46 to move.
Is automatically displaced upward by the urging force of the shaft portion 45a so that the shaft portion 45a is fitted into the shaft hole 42 and the knob 47 is attached to the bearing boss portion 4
The bosses 41 and 43 are connected by being fixedly held at a position where they abut on the lower surface of the boss 3. It should be noted that the lowering operation of the movable support shaft 45 is preferably performed by using a dedicated tool or the like in view of the relatively strong biasing force of the spring 46.

On the other hand, when disassembling the front frame B in the opposite manner to the above, first, the movable support shaft 4 in the upper opening / closing connection support means C1 is arranged.
5 is temporarily pulled down in the releasing direction to remove the shaft portion 45a from the shaft hole 42 of the support boss portion 41, so that both boss portions 4a
The connection of 1,43 is released. And under this, front frame B
Is slightly tilted to move the bearing boss 43 away from the support boss 41, and the entire front frame B is appropriately pulled up. As a result, the support shaft 53 and the shaft hole 55 in the lower opening / closing connection supporting means C2 are removed, and the connection between the boss portions 51 and 54 is released.

As described above, the front frame B assembled to the outer frame A by connecting the upper and lower open / close connection support means C1 and C2.
The upper and lower support shafts 45 and 53 are closed as the centers of rotation and are fitted to the opening front surface of the outer frame A. Thereby, the frame body 20
The relief recess 48 is laterally fitted to the support boss 41. On the other hand, the support seat 24 is placed on the receiving seat 8, and the pressing piece 83 of the outer frame A is pressed against the upper surface of the locking seat 84 of the frame body 20. In this state, the entire front frame B is stably held in an appropriate horizontal posture that is appropriately levitated with respect to the upper surface of the front plate portion 7 of the lower frame rod 4 of the outer frame A under the condition that the upward movement is prevented. ..
Then, in this closed state, the upper and lower hooks 63 of the locking means D engage with the receivers 64 of the outer frame A in a variable manner to be locked and held.

In the assembled and closed state of the front frame B,
By engaging the engaging support pieces 81 of each part on the back surface of the frame body 20 with the engaging surfaces 82 of the left and right side frame rods 2 and 3, respectively, the entire front frame B with respect to the outer frame A moves in the left-right direction. Rattling is preferably prevented, and a stable bond is maintained. As a result, when the entire pachinko machine is stored or transported in a sideways state, the total load of the entire front frame B side is directly applied to either the left or right side frame rods 2 and 3 engaged with the engaging support piece 81. The outer frame A will take over most of the time. Therefore, in the open / close connection support means C1 and C2 located on the left and right,
The total load on the front frame side is significantly reduced, and the action of a large external force in the shearing direction is avoided in advance. The deformation of the respective support shafts 45, 53 and the loosened boss portions 41, 43, 5
The deformation and crack damage of 1, 54 are eliminated.

Both frames A, which are assembled and engaged as described above,
The pachinko machine with B as the machine body is provided for the game by assembling and setting the entire front frame B side to the outer frame A installed at a required inclination angle for installation on the installation machine base F in a game shop or the like. Therefore, as an additional description of the installation mode of the outer frame A, as shown in FIGS. 5 and 6, the lower end front edge of the lower frame rod 4 is aligned with the reference position of the lower receiving plate 89, and the upper end front edge of the upper frame rod 1 is aligned. The upper plate 90 is appropriately moved backward with respect to a predetermined position to set the entire tilt angle. Under this condition, the nail N inserted into the nail hole 5 of the upper frame rod 1 is driven into the upper plate 90 to fix the upper side,
In the angle adjustment fixing portion 10 of the lower frame rod 4, the locking tooth belt 12
The set screw 17 is inserted into the long hole 11 from the seat hole 14 of the fixed platen 13 which is positionally engaged with the lower plate 89,
The fixing plate 13 is strongly tightened and fixed, and the lower side is positioned and fixed. By the way, when the outer frame A is changed and adjusted to another angle, it is possible to engage the fixing plate 13 with the locking tooth belt 12 at a predetermined position and fix it with the set screw 17.

In the above-mentioned embodiment, the upper and lower open / close connection support means C is used for inspection and repair of the back side of the front frame.
When the entire front frame B is opened based on 1 and C2, the open holding means E stably holds the front frame B at a predetermined position. That is, as can be understood from FIGS. 8, 12, and 13, in the opening holding means E, the movable locking rod 73 biased downward by the spring 76 is engaged in the range from the closed position of the front frame B to the opening position. The stop shaft 74 is in a state of being pressed toward the upper end surface of the front plate portion 7 of the lower frame rod 4 of the outer frame A while being depressed toward the inside of the hole 72, and based on the lower support shaft 53, It is rotated and displaced. Then, when the front frame B is opened at about 90 degrees, the movable locking rod 73 is moved to the same position to move the locking shaft 74 to the lower frame rod 4.
At the time of matching with the engagement hole 77, the lower end portion of the locking shaft 74 is pushed down by the pressing force of the spring 76 and is projected into the engagement hole 77.

In this state, in the movable locking rod 73, the knob 78 is engaged with the upper end of the support cylinder 71 to prevent the handle 78 from descending and falling, and the locking shaft 74 urged by the spring 76 is provided in the hole 72. While being vertically inserted and held between and the engaging hole 77, the frame 20 and the lower frame rod 4 are directly connected as a lock member. As a result, the entire front frame B is constrained and held stably at a fully open position of approximately 90 degrees, and further over-opening is restricted based on the same position, and fluctuations to the adjacent pachinko machine are prevented. At the same time, the closing return below that is regulated, and the variable return to the closing position is also prevented. Therefore, under the fully opened state of the front frame B, it is possible to avoid the interference with the player on the adjacent side, and even in the case where it takes a long time and involves two-handed operation, the tool is not bothered by fluctuations. You can operate the class properly and quickly and easily.

On the other hand, when the entire front frame B is returned to the original closed position at the end of work or the like, the movable locking rod 73 of the opening / closing holding means E is temporarily pulled up to engage the locking shaft 74 with the engaging hole 77. The frame body 20 and the lower frame rod 4 are unlocked by removing the frame body 20 from above. Therefore, thereafter, the entire front frame B can be quickly closed back based on the upper and lower open / close connection support means C1 and C2. To unlock the movable locking rod 73, the movable rod 73 may be released when the front frame B is slightly closed back while the rod 73 is temporarily pulled up and held. As a result, when the locking shaft 74 removed from the engagement hole 77 is pushed down again by the urging force of the spring 76, the lower end of the locking shaft 74 is moved to the upper end surface of the front plate portion 7 of the lower frame rod 4 (the engagement hole). 77 to the peripheral surface of the upper opening). Then, in this abutting state, the front frame B is displaced along the lower support shaft 53 in the closing back process.

In the gaming machine to which the present invention is applied, both frames A and B forming the machine body may be molded from materials other than synthetic resin material, and a technique relating to open / close connection support of both frames A and B. For the above, a pair of a support fitting and a receiving fitting, which are conventionally also called hinges, may be combined. On the assumption that the upper opening / closing connection supporting means C1 side is taken as an example, FIG.
As shown in FIG. 4, the movable support shaft 91 has a shaft portion 91a, a large-diameter support shaft portion 91b, and a small-diameter support rod 91c formed in series, and the shaft support hole 4 of the bearing boss portion 43 on the front frame B side.
4 is inserted and spring 46 always urges upward. Before the front frame B is assembled, the hook shaft 92 that pushes down the entire movable support shaft 91 against the spring 46 and projects to the support rod 91c.
Is locked to the lower end of the hook hole 94 of the seat base 93 fixed to the lower surface of the bearing boss 43, and the shaft 91a is supported by the support boss 4 on the outer frame A side.
It can be held in the non-fitting insertion position with respect to the first shaft hole 42. On the other hand, when assembling the front frame B, the entire movable support shaft 91 is appropriately rotated to align the hook shaft 92 with the hook hole 94. As a result, the support shaft 91 may be disengaged and moved upward by the urging force of the spring 46 so that the shaft portion 91 a can be inserted and inserted into the shaft hole 42 of the support boss portion 41. When operating the movable support shaft 91, the engaging groove 95 at the upper end of the shaft portion 91a is used.
Then, the required tools can be engaged with the square shaft portions 96 at the lower end of the support rod 91c.

As shown in FIG. 15, the movable boss 97 has a shaft portion 97a, a screw shaft portion 97b, and a support shaft portion 97c, which are formed in series to form a bearing boss portion 43.
The support 99 is fitted into the screw hole 100.
Then, the entire movable support shaft 97 is displaced up and down by the turning operation, and the shaft fitting 97a is fixed to the outer frame A.
Alternatively, the bearing sleeve 102 may be fitted and removed. An example is shown in which a tool engaging groove 98 is formed on the upper end of the shaft portion 97a and the lower end of the support shaft portion 97c so that the turning operation can be performed from above or below.

On the other hand, with respect to the technique for holding the front frame B open, as another example other than the above-mentioned embodiment, as shown in FIGS. 16 and 17, it is formed inside the lower left corner of the frame body 20 of the front frame B. Supporting cylinder portion 111 and the supporting hole 11 of the supporting cylinder portion 111.
