Description

  The present invention relates to a gaming machine such as a pachinko machine.

  Generally, in gaming machines such as pachinko machines, a gaming machine main body (inner frame) is provided to be openable and closable with respect to a fixed frame (outer frame) from the viewpoint of maintenance and the like. Therefore, the gaming machine is provided with a locking device so that a person other than the store clerk cannot open the gaming machine body without permission.

  As such a locking device, a main body locking mechanism that locks the gaming machine main body with respect to the fixed frame, and a front door locking mechanism that locks the gaming machine main body with a front door that can be opened and closed on the front side of the gaming machine main body. What you have is known. For example, a cylinder lock that is operated using a dedicated key, a main body hook member that is detachably attached to the engaged portion on the fixed frame side, and an engaged portion on the front door side. A front door saddle member detachably provided, a first transmission mechanism for transmitting the operation of the cylinder lock to the main body saddle member in response to a rotation operation in one direction by the key, and a key in the other direction There is one provided with a second transmission mechanism that transmits the operation of the cylinder lock according to the turning operation to the front door rod member. And, in the locked state of the gaming machine main body and the front door, each hook member is engaged with the corresponding engaged portion, so that the gaming machine main body cannot be opened with respect to the fixed frame, and the front door is attached to the gaming machine main body. On the other hand, it becomes impossible to open. In addition, by rotating the cylinder lock in one direction with a dedicated key, the main body saddle member is detached from the engaged portion, and the gaming machine main body can be opened. On the other hand, by rotating the cylinder lock in the other direction, the front door hook member is detached from the engaged portion, and the front door can be opened.

  In recent years, gaming halls have been used for illegal activities to acquire a large number of gaming media by illegally unlocking the gaming machine body during operation and illegally operating or exchanging control devices provided on the back side of the gaming machine. Sometimes it is. Such unauthorized unlocking is usually performed by inserting a wire such as a wire from the gap between the gaming machine main body and the fixed frame, and hooking the wire on the main body hook member of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on the main body hook member, the main body hook member is detached from the engaged portion, and the gaming machine main body can be opened.

In addition, as means for preventing an illegal act on a control device or the like, there is a locking device that locks a mechanism plate or the like provided on the back side of the gaming machine main body to the gaming machine main body (see, for example, Patent Document 1). In this way, if the mechanism plate or the like is locked to the gaming machine main body, it is difficult for an illegal act to the control device or the like to be performed.
JP-A-11-28284

  However, as in the invention described in Japanese Patent Application Laid-Open No. 11-28284, in the configuration in which the locking device for the mechanism plate is provided separately from the locking device for the gaming machine main body, there is a concern about an increase in the number of parts. Furthermore, since the positions of these locking devices, that is, the positions of the lock members into which the keys are inserted, are scattered at a plurality of locations, the operation of opening the mechanism plate during maintenance or the like may become troublesome.

  For this reason, in consideration of convenience, it is conceivable that the locking mechanism of the mechanism plate is integrated with the locking device including the locking mechanism of the gaming machine body and the locking mechanism of the front door. For example, when the cylinder lock is rotated in a predetermined direction with a dedicated key by combining the transmission mechanism that constitutes the locking mechanism of the front door, the front door hook member and the mechanism plate hook member are It can be set as the structure which can detach | leave from a to-be-engaged part, and can each open | release a front door and a mechanism board.

  However, in such a configuration, when one of the front door rod member and the mechanism plate rod member is detached from the engaged portion, the other flange member is also detached from the engaged portion at the same time. Therefore, when closing the front door in the open state, for example, after the maintenance on the front side of the gaming machine main body is finished, once the front door saddle member is displaced to the release side, the front door saddle member The mechanism plate saddle member is also displaced toward the separation side. Therefore, in some cases, such as when the momentum to close the front door is strong, the mechanism plate may be opened on the back side of the main body, or the mechanism plate position may shift and the mechanism plate saddle member may not return to the engaged position normally. There is a possibility that the engaged portion cannot be engaged. If the mechanism plate heel member does not return to the engaged position, the front door ridge member interlocked by the same transmission mechanism is also not engaged with the engaged portion, so that neither the front door nor the mechanism plate can be locked. . In such a state, as in the case of performing maintenance on the back side of the gaming machine main body, the gaming machine main body is once unlocked and opened, the mechanism plate is closed, and then the gaming machine main body is closed. It takes time-consuming work. In addition, when performing the operation of closing the mechanism plate in the open state, the same problem as described above that the front door is opened may occur. Thus, in the locking device having the above-described configuration, care must be taken when performing the locking and unlocking operations of the front door and the mechanism plate.

  In addition, the above-mentioned problem is a problem corresponding to a configuration in which, for example, a transmission mechanism that constitutes a locking mechanism of a gaming machine main body is used to interlock the main body hook member and the mechanism plate hook member, and the pachinko machine The problem is not limited to other game machines having the same structure.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a gaming machine capable of improving the defense performance against unauthorized unlocking and improving the convenience.

  Hereinafter, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

The amount of displacement of the engaging portion on the locking device side required for unlocking one of the opening / closing bodies is different from the amount of displacement of the engaging portion on the locking device side required for unlocking the other opening / closing body. As a result, one of the two opening / closing bodies (the one with the larger displacement amount of the engaging portion on the side of the locking device required for unlocking) remains unopenable and the other (the engaging portion on the side of the locking device required for unlocking). Can be opened. Further, for example, when closing the other opening / closing body in the open state, even if the engaging portion corresponding to the opening / closing body is once displaced to the unlocking allowable position, the engagement corresponding to the one opening / closing body is also performed. Since the joint portion does not reach the unlocking allowable position, the one opening / closing body is not released from the restriction and cannot be opened. Therefore, even if the momentum for closing the other opening / closing body is strong, there is no possibility that the one opening / closing body will be opened. Therefore, when performing the locking operation and the unlocking operation of the other opening / closing body, it is possible to reduce the influence on the one opening / closing body and to suppress the occurrence of the problems described in the above problem.

  As a result, it is possible to improve the defense performance against unauthorized unlocking and improve convenience such as improvement of workability during maintenance.

Similarly, a pair of upper and lower upper engagement holes 727 and 728 that can be engaged with the engagement claws 720a and 720b are formed in the bulging portion 636a of the second sliding rod 635. Further, a through hole 730 is formed in the support plate 603 so as not to hinder the operation of the engaging claws 720a and 720b.

  The engagement holes 725 and 726 of the first sliding rod 605 and the engaging holes 727 and 728 of the second sliding rod 635 are in a superimposed state of the first sliding rod 605 and the second sliding rod 635. At least the upper engagement holes 725 and 727 and the lower engagement holes 726 and 728 are in communication with each other (see FIG. 18).

  Further, on the first sliding rod 605 side, the lower engagement hole 726 is set to have a longer vertical formation section than the upper engagement hole 725 out of both the engagement holes 725 and 726. On the other hand, on the second sliding rod 635 side, the upper engagement hole 727 has a longer vertical formation section than the lower engagement hole 728 of the two engagement holes 727 and 728. . As described later, when the cam plate 720 slides one of the first sliding rod 605 or the second sliding rod 635, the upper engagement claw 720a or the lower engagement claw 720b is not brought into contact with the other. In order to prevent the other from sliding.

  18A, when the lock shaft 703 and the cam plate 720 are at the reference position when the key K is not inserted into the key hole 702 of the cylinder lock 700, as shown in FIG. The tip of the upper engagement claw 720a is inserted into the upper engagement holes 725 and 727 of the first sliding rod 605 and the second sliding rod 635, and the tip of the lower engagement claw 720b is the first sliding rod. The hook 605 and the second sliding rod 635 are inserted into the lower engagement holes 726 and 728. In addition, as described above, the cylinder lock 700 according to the present embodiment is in a state (locked state) in which the lock shaft 703 and the cam plate 720 cannot be rotated when the key K is not inserted into the key hole 702. When the cam plate 720 is at the reference position, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted by the engaging claws 720a and 720b. For example, when an external force in the unlocking direction is applied to the first sliding rod 605 by improperly hooking a wire or the like on the first sliding rod 605 at the reference position without using the key K The engaging claws 720a and 720b are hooked on the edges of the engaging holes 725 and 726 of the first sliding rod 605, and the sliding displacement of the first sliding rod 605 in the unlocking direction causes the engaging hole 725 to move. It is practically regulated except for the play length.

  Next, the operation of the locking device 600 will be described in detail. First, locking and unlocking of the front frame set 14 will be described in detail. In the locked state of the front frame set 14, as shown in FIG. 20A, the first slide bar 605 takes the reference position, so that the front frame set bar 610, 611, 612 is not in the front frame set 14. The front metal frame 17 is locked on the front surface side through the locking holes 17a, 17b, and 17c of the metal fitting 17, and the opening of the front frame set 14 is restricted. FIG. 20 is a view for explaining the movement of the first sliding rod 605.

  When the front frame set 14 is unlocked, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated counterclockwise as viewed from the front side of the pachinko machine 10 (see FIG. 1). This operation corresponds to the operation in the second direction by the key K in the present embodiment. As a result, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a contacts the lower edge portion of the upper engagement hole 725 of the first sliding rod 605 (see FIG. 18B). However, since FIG. 18B is a view seen from the back side of the pachinko machine 10, the rotation direction of the cam plate 720 is the clockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes the first sliding rod 605 downward against the tensile force of the coil spring C1. At the same time, the lower engaging claw 720b is detached from both the lower engaging holes 726 and 728 without acting on the first sliding rod 605 and the second sliding rod 635. At this time, a space for the upper engagement claw 720a to be displaced downward is secured below the upper engagement hole 727 of the second sliding rod 635 through which the upper engagement claw 720a is inserted. In the process of pushing down the moving rod 605, the upper engaging claw 720a does not come into contact with the second sliding rod 635 so that the operation is not hindered.

  When the first sliding rod 605 slides downward, when the key K is rotated about 45 degrees in the counterclockwise direction, as shown in FIG. , 612 and the bracket 17 are released, and the front frame set 14 is allowed to be opened. That is, the displacement amount X1 of the first sliding rod 605 corresponding to the amount of rotation of the key K about 45 degrees in the counterclockwise direction is such that the front frame set collar portion 610, 611, 612 moves from the locked position to the unlockable position. This corresponds to the amount of displacement required to reach, that is, the amount of displacement of the front frame set collars 610, 611, and 612 required to unlock the front frame set 14.

  At this stage, as will be described later, since the back pack collars 621 and 622 have not reached the unlocking allowable position, the back pack unit 203 cannot be opened.

  When the front frame set 14 is opened, if the force of the hand operating the key K is loosened, the first sliding rod 605 is pulled upward by the tensile force of the coil spring C1, and returns to the reference position. . Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  Next, locking and unlocking of the inner frame 12 will be described in detail. In the locked state of the inner frame 12, the second sliding rod 635 takes the reference position, so that the inner frame flange portions 637 and 638 are locked to the receiving fittings 83 and 84 of the outer frame 11, and the inner frame 12 is opened. Is regulated.

  Then, when unlocking the inner frame 12, the key K is inserted into the key hole 702 of the cylinder lock 700 and rotated clockwise as viewed from the front side of the pachinko machine 10. This operation corresponds to the operation in the first direction by the key K in the present embodiment. Thereby, the cam plate 720 rotates in the same direction, and the lower engagement claw 720b contacts the upper edge portion of the lower engagement hole 728 of the second sliding rod 635 (see FIG. 18C). However, since FIG. 18C is a view from the back side of the pachinko machine 10, the rotation direction of the cam plate 720 is the counterclockwise direction.

  Thereafter, as the cam plate 720 is further rotated, the lower engagement claw 720b pushes the second sliding rod 635 upward against the tensile force of the coil spring C1. At the same time, the upper engaging claw 720a is detached from the upper engaging holes 725 and 727 without acting on the first sliding rod 605 and the second sliding rod 635. At this time, a space for the lower engagement claw 720b to be displaced upward is secured above the lower engagement hole 726 of the first sliding rod 605 through which the lower engagement claw 720b is inserted. In the process of pushing up the moving rod 635, the lower engaging claw 720b does not come into contact with the first sliding rod 605 so that its operation is not hindered.

  When the second sliding rod 635 slides upward, the engagement between the inner frame collar portions 637 and 638 and the receiving fittings 83 and 84 is released when the key K is rotated about 90 degrees in the clockwise direction. The opening of the inner frame 12 is allowed. That is, the amount of displacement of the second sliding rod 635 corresponding to the rotation of the key K by about 90 degrees in the clockwise direction is the displacement required for the inner frame collar portions 637 and 638 to reach the unlocking permitted position from the locked position. This corresponds to the amount, that is, the amount of displacement of the inner frame collars 637 and 638 required for unlocking the inner frame 12.

  Further, when the force of the hand operating the key K is loosened when the inner frame 12 is opened, the second sliding rod 635 is pulled downward by the tensile force of the coil spring C1, and returns to the reference position. Along with this, the cam plate 720 and the lock shaft 703 also return to the reference position.

  Next, locking and unlocking of the back pack unit 203 will be described in detail. In the locked state of the back pack unit 203, as in the case of the front frame set 14, the first slide bar 605 takes the reference position, so that the back pack bar parts 621 and 622 are received by the receiving bracket 204 of the back pack unit 203. Through the locking holes 204a and 204b, the back side of the backing metal 204 is locked, and the opening of the back pack unit 203 is restricted.

  When unlocking the back pack unit 203, the inner frame 12 is opened, and the key K inserted into the key hole 702 of the cylinder lock 700 is inserted in the front side of the pachinko machine 10 in the same manner as the front frame set 14. Turn counterclockwise as viewed from the top. As a result, the cam plate 720 rotates in the same direction, and the upper engagement claw 720a contacts the lower edge portion of the upper engagement hole 725 of the first sliding rod 605. Thereafter, as the cam plate 720 is further rotated, the upper engaging claw 720a pushes the first sliding rod 605 downward against the tensile force of the coil spring C1.

  When the first sliding bar 605 slides downward, the key K is rotated about 90 degrees counterclockwise, and as shown in FIG. 20 (c), all the back pack hooks 621, 622 and The engagement with the receiving bracket 204 is released, and the opening of the back pack unit 203 is allowed. That is, the amount of displacement X2 of the first sliding rod 605, which is the amount by which the key K is rotated about 90 degrees counterclockwise, is changed until the back pack collar 621, 622 reaches the unlocking permitted position from the locked position. This corresponds to the amount of displacement required, that is, the amount of displacement of the back pack collars 621 and 622 required for unlocking the back pack unit 203.

  As described above, in the present embodiment, when the key K is not inserted into the key hole 702 of the cylinder lock 700, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. When the inner frame 12, the front frame set 14, or the back pack unit 203 in the open state is locked, the lock cannot be performed unless the key K is used. For this reason, for example, when the open inner frame 12 is closed without using the key K, the inclined guide portions of the head portions 637b and 638b of the inner frame collar portions 637 and 638 collide with the receiving metal fittings 83 and 84. Even if an upward external force is applied to the second sliding rod 635, the second sliding rod 635 does not slide upward, and the inner frame 12 cannot be closed. Therefore, when the inner frame 12 in the open state is locked, the cylinder lock 700 is operated using the key K, and the position where it is not obstructed by the receiving fittings 83 and 84, that is, the inner frame collars 637 and 638 are unlocked. With the second sliding rod 635 slid to the position, the inner frame 12 was closed, and the heads 637b and 638b passed over the receiving fittings 83 and 84, and the inner frame 12 was completely closed. Above, the method of returning the 2nd sliding rod 635 to a latching position is taken. In addition, a method of closing the inner frame 12 without operating the key K while the key K is inserted into the key hole 702 of the cylinder lock 700 is also possible. In this case, when the inner frame 12 is closed and the inclined guide portions of the head portions 637b and 638b of the inner frame collar portions 637 and 638 collide with the receiving metal fittings 83 and 84, the inclined guide part and the receiving metal fittings 83 and 84 are connected. An external force in the upward direction is applied to the second sliding rod 635 while being in sliding contact, and the second sliding rod 635 slides upward against the tensile force of the coil spring C1. Then, when the heads 637b and 638b of the inner frame flange portions 637 and 638 get over the receiving fittings 83 and 84, the second sliding rod 635 returns to the original position by the tensile force of the coil spring C1. As a result, the inner frame collar portions 637 and 638 are locked to the metal fittings 83 and 84. Of course, the front frame set 14 and the back pack unit 203 are also locked by the same locking method.

  As described above in detail, in this embodiment, the locking mechanism of the inner frame 12, the locking mechanism of the front frame set 14, and the locking mechanism of the back pack unit 203 are integrated into one locking device 600. In addition, it is possible to improve convenience such as improvement in workability during maintenance.

  In addition, the flange portions such as the inner frame flange portions 637 and 638 are integrally formed with the first slide rod 605 and the second slide rod 635, and the key K is not inserted into the key hole 702 of the cylinder lock 700. Then, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. For this reason, for example, even when a direct unlocking operation, that is, an unauthorized unlocking operation is performed on the first sliding rod 605 or the second sliding rod 635 with a wire or the like without using the key K, the first Since the sliding rod 605 or the second sliding rod 635 is maintained at the reference position, the opening of the inner frame 12 or the like is not allowed. As a result, the defense performance against unauthorized unlocking using a wire or the like is improved.

  Further, the back pack unit 203 is disposed on the back side of the inner frame 12 so as to cover the control device such as the main controller 261 and the back pack unit 203 is locked to the inner frame 12. . For this reason, it is difficult for the back pack unit 203 to perform an illegal act on the control device such as the main control device 261.

  In addition, in the present embodiment, the front frame set 14 and the back pack unit 203 that can be locked and unlocked by the operation in the same direction with the key K are the first required for unlocking the front frame set 14. The amount of displacement of the sliding collar 605 (front frame set collar 610, 611, 612) and the amount of displacement of the first sliding collar 605 (back pack collar 621, 622) required for unlocking the back pack unit 203 It is different. Accordingly, the front pack unit 610, 611, and 612, which are locked by the front frame set hooks 610, 611, and 612 with a small amount of displacement, remain in a state in which the back pack unit 203 locked by the back pack hooks 621 and 622 that require a larger amount of displacement cannot be opened. The frame set 14 can be opened. Accordingly, when the front frame set 14 in the open state is closed without operating the key K, for example, after the maintenance on the game board 30 is finished, the front frame set collar corresponding to the front frame set 14 is temporarily provided. Even if 610, 611, 612 is displaced to the unlocking permitted position, the back pack collars 621, 622 corresponding to the back pack unit 203 do not reach the unlocking permitted position. It cannot be opened. Therefore, even if the momentum for closing the front frame set 14 is strong, there is no possibility that the back pack unit 203 is opened on the back side of the inner frame 12 in the closed state. As a result, when the front frame set 14 is locked or unlocked, the influence on the back pack unit 203 can be reduced, and the occurrence of problems as described in the above problem can be suppressed.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) The configuration of the locking device 600 is not limited to the above embodiment. For example, in the above-described embodiment, regarding the locking mechanism of the front frame set 14, the front frame set collars 610, 611, 612 having claw portions are provided on the locking device 600 side, and these are engaged with the front frame set 14 side. A receiving bracket 17 is provided as an engaged portion. For example, as shown in FIG. 21A, a hook part (engaged part) 900 having a claw part is provided on the front frame set 14 side, and the hook part 900 is engaged with the locking device 600 side. It is good also as a structure in which the front frame set engaging part 901 to match is provided. In this case, at the time of unlocking, the engaging portion 901 (first sliding rod 605) on the locking device 600 side operates, so that the engaged state of both is released.

  Of course, the same structure can be applied to the locking mechanism of the inner frame 12 and the back pack unit 203. For example, as shown in FIG. 21 (b), a back pack unit 903 having a claw portion (engaged portion) 903 on the back pack unit 203 side and engaged with the hook portion 903 on the locking device 600 side is provided. It is good also as a structure in which the joint part 904 was provided.

  (B) In the above embodiment, the front frame set 14 and the back pack unit 203 can be locked and unlocked by an operation in the same direction with the key K. Not only this but the structure which can perform the locking operation | work and unlocking operation | work of the inner frame 12 and the back pack unit 203 by the operation to the same direction with the key K is good. For example, as shown in FIG. 21 (c), the second sliding rod 635 may be provided with a backpack collar 905 and the like together with an inner frame collar 637 and the like.

  Further, for example, the inner frame 12 and the front frame set 14 are unlocked by rotating the key K counterclockwise, and the back pack unit 203 is unlocked by rotating clockwise. As described above, the mechanism for performing the locking / unlocking operation of the inner frame 12 and the front frame set 14 and the mechanism for performing the locking / unlocking operation of the back pack unit 203 may not be interlocked.

  For example, by providing the front frame set collars 610, 611, 612 for the front frame set 14 and the inner frame collars 637, 638 for the inner frame 12 so as to move in conjunction with the first sliding collar 605, By operating the key K in the same direction, the front frame set collars 610, 611, 612 are detached from the receiving bracket 17, and the inner frame collars 637, 638 are detached from the receiving brackets 83, 84. it can.

  In this way, the locking / unlocking operation of the inner frame 12 or the front frame set 14 can be performed without interlocking with the locking / unlocking operation of the back pack unit 203. When performing the locking / unlocking operation of the set 14, there is no problem that the back pack unit 203 is opened.

  In this case, the displacement amount of the first sliding rod 605 (front frame set flange portions 610, 611, 612) required for unlocking the front frame set 14 is further determined by the first sliding rod 605 required for unlocking the inner frame 12. If it is set to be smaller than the displacement amount of the (inner frame collar parts 637, 638), the front frame set collar part 610 remains in a state where the inner frame 12 locked by the inner frame collar parts 637, 638 cannot be opened. , 611, 612 can be opened.

  For example, when the key K is rotated about 45 degrees in the counterclockwise direction, the engagement of all the front frame set collars 610, 611, 612 and the receiving bracket 17 is released, and the front frame set 14 is opened. Is acceptable. At this stage, since the inner frame collars 637 and 638 have not reached the unlocking allowable position, the inner frame 12 cannot be opened. Further, the key K is further rotated counterclockwise, and when the operation amount reaches about 90 degrees, the engagement between the inner frame collar parts 637 and 638 and the receiving metal parts 83 and 84 is released, Opening of the frame 12 is allowed.

  By adopting such a configuration, when the front frame set 14 in the open state is closed without operating the key K, for example, after maintenance on the game board 30 is completed, the front frame set 14 is temporarily supported. Even if the front frame set collars 610, 611, 612 to be moved are displaced to the unlocking permitted position, the inner frame collars 637, 638 corresponding to the inner frame 12 do not reach the unlocking permitted position. Is not deregulated and cannot be opened. Therefore, even if the momentum for closing the front frame set 14 is strong, there is no possibility that the inner frame 12 in the closed state will be opened.

  In place of this, the displacement amount of the first sliding bar 605 (front frame set bar 610, 611, 612) required for unlocking the front frame set 14 is the first slide required for unlocking the inner frame 12. Even when it is set to be larger than the displacement amount of the moving rod 605 (inner frame collar portions 637 and 638), the influence on the back pack unit 203 is similarly reduced.

  (C) In the above embodiment, the displacement amount X2 of the first sliding bar 605 (back pack bar 621, 622) required for unlocking the back pack unit 203 is the first slide required for unlocking the front frame set 14. It is set to be larger than the displacement amount X1 of the moving rod 605 (front frame set collar portion 610, 611, 612). Not limited to this, the displacement amount X2 of the first sliding rod 605 required for unlocking the back pack unit 203 is set to be smaller than the displacement amount X1 of the first sliding rod 605 required for unlocking the front frame set 14. It is good also as a structure.

  Similarly, in the configuration in which the second sliding rod 635 is provided with the back pack collar portions 621 and 622 together with the inner frame collar portions 637 and 638, the second sliding rod 635 (required for unlocking the back pack unit 203). The displacement amount of the back pack collars 621, 622) may be set larger or smaller than the displacement amount of the second sliding collar 635 (inner frame collars 637, 638) required for unlocking the inner frame 12. May be.

  When the amount of displacement of the back pack collars 621 and 622 required for unlocking the back pack unit 203 is set small, the inner frame 12 or the front frame set is used when the back pack unit 203 is locked or unlocked. Generation | occurrence | production of the malfunction which 14 will be open | released can be suppressed. Conversely, when the displacement amount of the back pack collars 621 and 622 required for unlocking the back pack unit 203 is set large, as described in the above embodiment, the locking operation of the inner frame 12 or the front frame set 14 is performed. When the unlocking operation is performed, it is possible to suppress the occurrence of a problem that the back pack unit 203 is opened. In particular, since the back pack unit 203 is on the back side of the inner frame 12, there is a risk that it will open without being noticed. If the back pack unit 203 is opened in this way, the inner frame once A very laborious work such as closing the back pack unit 203 after opening 12 is required. Therefore, in order to eliminate such a problem, it is more preferable that the displacement amount of the back pack collars 621 and 622 required for unlocking the back pack unit 203 is set large.

  (D) In the above embodiment, the inner frame 12 is unlocked by inserting the key K into the key hole 702 of the cylinder lock 700 and rotating in the clockwise direction, and rotating in the counterclockwise direction. The frame set 14 and the back pack unit 203 are unlocked. However, the operation direction using the key K, that is, the sliding direction of the first sliding rod 605 and the second sliding rod 635 may be reversed. In the above embodiment, for example, the inner frame flange portions 637 and 638 are separated from the metal fittings 83 and 84 when the second sliding rod 635 slides upward. The inner frame collar portions 637 and 638 may be detached from the receiving metal fittings 83 and 84 by sliding downward.

  (E) The configuration of the flanges such as the front frame set flange 610 is not limited to the above embodiment. For example, in the above-described embodiment, the flanges such as the front frame set collar 610 are integrally formed with the first slide collar 605 and the second slide collar 635. However, the present invention is not limited thereto, and the front frame set collar 610 is not limited thereto. It is good also as a structure fixed to the 1st sliding rod 605 and the 2nd sliding rod 635 so that relative displacement is impossible by the fixing means, such as a screw | thread.

  Further, in the above embodiment, the collar portion having a substantially triangular head tapered toward the tip is adopted, but the present invention is not limited to this, for example, the tilt guide portion is omitted, and the tip of the head is vertically moved. You may employ | adopt the collar part formed in the substantially linear form along the direction. In the above embodiment, a configuration is adopted in which the sliding displacement of the first sliding rod 605 and the second sliding rod 635 is regulated by the cam plate 720 when the key K is not inserted into the cylinder lock 700. If the inner frame 12 or the like in the open state is forcibly closed without using the key K, a force in the unlocking direction is applied to the first sliding rod 605 and the second sliding rod 635, and the cam plate 720 May be damaged. On the other hand, when the above configuration is adopted, when the inner frame 12 or the like in the open state is closed without using the key K, the head tips of the collars such as the inner frame collars 637 and 638 are received by the metal fittings. Even when it comes into contact with the engaged parts such as 83 and 84, the first sliding rod 605 and the second sliding rod 635 are not applied with a force in the unlocking direction, so the above problem does not occur.

  Further, the number of the hooks such as the inner frame hooks 637 and 638 and the engaged parts such as the receiving metal fittings 83 and 84 corresponding to the hooks are not limited to the number of the above embodiments. There may be one.

  (F) In the above-described embodiment, the flanges such as the inner frame flanges 637 and 638 are integrally formed with the first sliding rod 605 and the second sliding rod 635, and the key K is inserted into the key hole 702 of the cylinder lock 700. In a state where is not inserted, the sliding of the first sliding rod 605 and the second sliding rod 635 is restricted. Not only this but each collar part, such as inner frame collar part 637,638, is provided in the 1st sliding collar 605 or the 2nd sliding collar 635 so that relative displacement is possible, and each collar member is each independently sliding displacement. It is good also as a possible structure. In this way, even if the front frame set collar 610 or the like is displaced when the front frame set 14 is closed without operating the key K, the back pack collar 621 or the like is not displaced. Therefore, there is no possibility that the back pack unit 203 is unlocked when the front frame set 14 is locked. Of course, when unlocking, the above-mentioned problem can be suppressed by providing a difference in the amount of displacement between the two as in the above embodiment. Further, with such a configuration, it is possible to displace all the collars such as the inner frame collar 637 and the front frame set collar 610 with a single sliding collar, thereby reducing the number of parts. be able to. However, in terms of enhancing the defense performance against unauthorized unlocking, each of the flanges may be provided on the first sliding rod 605 and the second sliding rod 635 so as not to be relatively displaceable as in the above embodiment. preferable.

  (G) In the above embodiment, the front frame is changed by making the projection length T1 of the claw portions of the front frame set collar portions 610, 611, 612 different from the projection length T2 of the claw portions of the back pack collar portions 621, 622. The displacement amount X1 of the first sliding rod 605 required for unlocking the set 14 is different from the displacement amount X2 of the first sliding rod 605 required for unlocking the back pack unit 203. For example, the amount of displacement X1 required for unlocking the front frame set 14 can be changed by changing the relationship between the hooks and the engaged parts engaged with the hooks. The displacement amount X2 required for unlocking the pack unit 203 may be different. In this case, even if the projection length T1 of the claw part such as the front frame set collar part 610 and the projection length T2 of the claw part such as the back pack collar part 621 are the same, both displacement amounts X1 and X2 required for unlocking are obtained. Can be different.

  (H) In the above embodiment, the protrusion length T2 of the claw portions such as the back pack collar portion 621 is set to be approximately twice the protrusion length T1 of the claw portions such as the front frame set collar portion 610. That is, the displacement amount X2 of the first sliding rod 605 required for unlocking the back pack unit 203 is set to about twice the displacement amount X1 of the first sliding rod 605 required for unlocking the front frame set 14. Yes. However, the difference between the two is not limited to this, and may be more or less. However, if the difference between the two is too small, the effects of the present invention may not be sufficiently exhibited, which is not preferable.

  (I) In the above embodiment, one backpack unit 203 is provided on the back side of the inner frame 12 so as to be openable and closable as a rear door body.

In addition, when the flanges such as the inner frame flanges 637 and 638 are configured to be relatively displaceable with respect to the first sliding rod 605 and the second sliding rod 635, etc. It is good also as a structure which provided the biasing means.

  (K) A cylinder lock different from the cylinder lock 700 may be adopted. For example, the cylinder lock 700 of the above embodiment is locked when the key K is not inserted, and the cam plate 720 cannot be displaced. When the first sliding rod 605 and the second sliding rod 635 are in the reference position, the tip of the upper engaging claw 720a is engaged with the upper engagement of the first sliding rod 605 and the second sliding rod 635. The holes 725 and 727 are inserted, and the tips of the lower engagement claws 720 b are inserted into the lower engagement holes 726 and 728 of the first sliding rod 605 and the second sliding rod 635. Thereby, sliding of the 1st sliding rod 605 and the 2nd sliding rod 635 will be controlled. However, the present invention is not limited to this, and a cylinder lock in which the cam plate 720 cannot be displaced may be employed. Further, when the first sliding rod 605 and the second sliding rod 635 are in the reference position, the engaging claws 720a and 720b are not inserted into the engaging hole 725 and the like, and the first sliding rod 605 and the second sliding rod 605b are not inserted. A configuration in which sliding of the two sliding rods 635 is not restricted may be adopted. In other words, the key K may not be required when the front frame set 14 and the inner frame 12 are closed.

  Moreover, you may employ | adopt the cylinder lock which can change a key code. As an example of the procedure for changing the key code, first, the current key is inserted into the keyhole while a predetermined reset pin is pressed, and then the key is pulled out. Then, while holding down the reset pin, a key to be newly set is inserted into the key hole, and the key is pulled out after releasing the pressed state of the reset pin after rotating in the opposite direction to the current key. By performing the operation as described above, a key code suitable for a new key to be set can be obtained. As a result, the key can be unified for each game hall, and the key can be changed periodically to prevent fraud.
