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. Such a locking device includes a cylinder lock that is operated using a dedicated key, a plurality of hook members that are detachably attached to a plurality of locked portions that are provided on a fixed frame, and a cylinder that uses a key. There has been known one provided with a transmission mechanism for interlocking a plurality of scissors members according to an unlocking operation of the lock. And in a locked state, each gutter member engages with the corresponding to-be-latched part, respectively, and a game machine main body cannot open | release with respect to a fixed frame. On the other hand, when the cylinder lock is unlocked with a dedicated key, the hook members are simultaneously detached from the locked portions via the transmission mechanism, and the gaming machine main body 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. It has been broken. 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 to a hook member of the locking device and moving it in the unlocking direction. When an unauthorized unlocking operation is performed on any one of the collar members, the operation is transmitted to the other collar member via the transmission mechanism, and all the collar members are interlocked and detached from the locked portion. The gaming machine body can be opened.

  On the other hand, a mechanism for blocking the transmission of the movement of the hook member according to the unauthorized unlocking operation performed on any one of the hook members to the other hook member that is not unlocked, Some are provided with a cover member that covers the periphery of the flange member so as to make it difficult to hook a wire or the like (see, for example, Patent Document 1).

JP 2001-120817 A

  However, even if the transmission blocking mechanism is provided, if an unauthorized unlocking operation is simultaneously performed on a plurality of eaves members, the unlocking mechanism may be unlocked. Even if the cover member is provided, it is difficult to prevent the unauthorized unlocking operation because the wire rod can be easily hooked on the hook member of the locking device if a hole is made in the surface of the gaming machine.

  The above-mentioned problem is not limited to the locking mechanism that locks the gaming machine main body and the outer frame. For example, the locking mechanism that locks the gaming machine main body and an opening / closing member that can be opened and closed with respect to the gaming machine main body.

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

Means 1. A door body supported to be openable and closable on one side on the left and right sides of the fixed frame;
A gaming machine provided with locking means for locking the door body on the left and right other sides with respect to the fixed frame,
The locking means is
A locking member operated by a key;
A sliding member that is slidable in the vertical direction in conjunction with the operation of the lock member according to the operation of the key;
A locking position that is engaged with the sliding member so as to be relatively displaceable, and that is locked to a predetermined locked portion in conjunction with the operation of the sliding member to restrict the opening of the door body. And a scissor member that slides and displaces in the vertical direction while substantially maintaining a reference posture at a non-locking position that allows the door body to be released by being detached from the locked portion,
A regulating means capable of regulating sliding displacement in the unlocking direction of the flange member from the locking position toward the non-locking position;
When an external force in the unlocking direction is applied to the hook member in the locking position from other than the sliding member, the posture of the hook member changes and the unlocking direction of the hook member The gaming machine is characterized in that sliding displacement is regulated by the regulating means.

  According to the said means 1, at the time of locking, a collar member is latched by the to-be-latched part, and opening of a door body is controlled. When the unlocking operation is performed using the key, the lock member operates in accordance with the operation. The operation of the locking member is transmitted to the eaves member via the sliding member, the eaves member is detached from the locked portion, and the door body is allowed to open. On the other hand, when a direct unlocking operation, i.e., an unauthorized unlocking operation, is performed on the rod member with a wire or the like without using a key, the posture of the rod member with respect to the sliding member is changed and the rod member The sliding displacement in the unlocking direction is regulated by the regulating means. For example, when an unauthorized unlocking operation is performed on the eaves member, the eaves member rotates, and a part of the eaves member protrudes from the normal sliding path to the outside of the path, thereby restricting means such as a locking claw Thus, sliding displacement in the unlocking direction is regulated. Thereby, since a collar member is maintained in a latching position, opening of a door body is not permitted. As a result, the defense performance against unauthorized unlocking using a wire or the like is improved. Of course, the number of hook members and the number of locked portions corresponding thereto is not limited to one, and a plurality of these may be provided. In this case, the restriction means is provided corresponding to each of the plurality of flange members. Therefore, even when an unauthorized unlocking operation is simultaneously performed on a plurality of eaves members, the opening of the door body is not permitted. Examples of the lock member include a cylinder lock that is rotated by inserting a key. Further, the locked portion is provided on the opposite side of the fixed frame or the door body to the side where the locking means is provided.

A locking member operated by a key;
In conjunction with the operation of the lock member in response to the operation of the key, a sliding member that can slide in the vertical direction along the support portion;
A base portion that is located closer to the mounting portion side than the protruding side edge portion of the support portion and is engaged with the sliding member so as to be relatively displaceable, and that protrudes from the base portion and is supported by the protruding side edge portion. Comprising a collar member provided with a locking part located on the outside of the part;
The hook member is locked to a locked portion provided on the other side of the fixed frame or the door body in conjunction with the operation of the sliding member, and locks to restrict the opening of the door body. The structure is configured to slide and displace in the vertical direction while substantially maintaining the reference posture at the position and the non-locking position that allows the door body to be released by being detached from the locked part,
A gaming machine comprising a restricting means capable of restricting sliding displacement of the hook member in the unlocking direction from the locking position toward the non-locking position.

  According to the means 2, when a wire or the like is hooked on the locking portion of the hook member at the locking position and an external force is applied to the locking portion in the unlocking direction, the posture of the hook member is changed from the reference posture. The rotation changes, and the sliding displacement of the flange member in the unlocking direction is restricted by the restricting means. As a result, the same effects as those of the means 1 are achieved.

Means 3. A gaming machine body supported to be openable and closable at one side on the left and right sides of the fixed frame;
A front door supported to be openable and closable at the left and right sides with respect to the gaming machine body;
A gaming machine comprising: a locking means for locking the gaming machine main body at the left and right other side with respect to the fixed frame; and locking the front door at the left and right other side with respect to the gaming machine main body. And
The locking means is
A vertically long base frame comprising a mounting portion attached along the left and right other sides of the gaming machine main body, and a support portion projecting from the mounting portion toward the fixed frame;
A locking member operated by a key;
In conjunction with the operation of the lock member in response to the operation of the key, a sliding member that can slide in the vertical direction along the support portion;

A hook member which is provided with a locking portion located on the outer side, and the locking portion is locked to a locked portion provided on the fixed frame side;
An engagement member that engages with an engaged portion provided on the front door side,
In conjunction with an operation in which the sliding member slides upward or downward from a reference position, the hook member is locked to the locked portion to prevent the gaming machine body from opening. , Slidably displaced in one of the up and down directions while substantially maintaining a reference posture, to a non-locking position that allows the game machine body to be released from the locked portion.
In conjunction with the sliding movement of the sliding member from the reference position to the other in the vertical direction, the engagement member engages with the engaged portion to restrict the opening of the front door. , Is configured to slide and displace to the other side in the up-down direction to a non-engagement position that allows the front door to be opened by separating from the engaged portion,
A gaming machine comprising a restricting means capable of restricting sliding displacement of the hook member in the unlocking direction from the locking position toward the non-locking position.

  According to the means 3, the same effects as the means 1 and 2 can be obtained. Moreover, in the said means 3, unlocking of a game machine main body and unlocking of a front door can be performed separately, sharing a sliding member. As a result, the gaming machine main body and the front door can be opened separately, so that workability during maintenance and the like can be improved, and an increase in the number of parts can be suppressed.

  In order to prevent the hook member from being moved to the unlocked position by an unlocking operation directly performed on the hook member by a wire or the like without using a key, that is, an unauthorized unlocking operation, for example, the hook member is slid. It is fixed so that it does not displace relative to the moving member, and both are integrally slidably displaced. When the key is not inserted into the locking member, the locking state of the locking member is not released, and the cam plate of the locking member If the sliding member engaged with the sliding member cannot slide, the sliding displacement of the eaves member in the unlocking direction can be restricted. However, when the sliding member is commonly used for unlocking the gaming machine body and the front door as in the above means 3, the saddle member can be moved at least up and down relative to the sliding member (relative to the top and bottom). It is necessary to employ a configuration that engages with the displacement. Therefore, it is necessary to prevent the eaves member from moving up and down by a direct unlocking operation for the eaves member while adopting a configuration in which the eaves member can be moved up and down with respect to the sliding member. That is, in such a configuration, the restriction means is more effective.

  Means 4. The restricting means is a hole or a recess formed in a portion facing the side edge of the base portion of the flange member at the locking position on the attachment portion side or the protruding side edge portion side of the support portion. A gaming machine described in the means 2 or 3, characterized in that it exists.

  According to the means 4, when the collar member is rotated from the reference posture at the locking position, a part of the base portion is inserted into the hole portion or the recess portion, so that the edge portion of the hole portion or the recess portion is inserted. The sliding displacement of the eaves member in the unlocking direction is restricted. In addition, when providing a hole part or a recessed part in the protrusion side edge part side of a support part, it forms along the protrusion side edge part of a support part, for example so that sliding of a collar member (base part) may be guided. It will be formed in a flange-shaped guide portion or the like.

  If a protrusion, which serves as a restricting means, is provided on the mounting portion, etc., the sliding path of the collar member (base part) should be such that the projection part does not interfere with the sliding of the collar member (base part) in the reference posture. The width of the support portion (the distance between the mounting portion and the protruding side edge portion of the support portion) needs to have a useless clearance more than the play necessary for sliding the flange member (base portion).

  On the other hand, by forming the restricting means as a hole or a recess in the mounting portion or the like, it is not necessary to form a useless protruding portion serving as the restricting means, so the width of the support portion is reduced as much as possible, and the locking means is enlarged. Can be suppressed. As a result, when the eaves member is in the standard posture while providing the restricting means (hole or recess), the eaves member is guided between the mounting portion and the protruding side edge portion (guide portion) of the support portion. Since the eaves member can be slid while being made, the stability of the sliding operation of the eaves member can be enhanced.

  Further, if a recess is formed in a part that can come into contact with the peripheral edge of the hole or the recess when rotating, on the side of the attachment part side edge or the support part protruding side edge of the flange member, a hole such as an attachment part is formed. A desired amount of rotation of the eaves member can be ensured while setting the length of the portion or the recess in the vertical direction to be relatively short. Therefore, it is possible to suppress a problem that the uselessly large hole or recess is provided to reduce the stability of the sliding motion of the eaves member.

Means 5. The locking portion has a protruding side edge formed along the vertical direction,
The locked portion has a restricting portion that is formed along the vertical direction and can contact the protruding side edge of the locking portion;
Biasing means for biasing the flange member to the locking position which is a reference position;
When the flange member is in the reference position,
The height position of the end portion on the locking direction side of the upper and lower end portions of the protruding side edge portion of the locking portion is the end position on the unlocking direction side of the upper and lower end portions of the restricting portion of the locked portion. Located on the locking direction side from the height position,
The height position of the end on the unlocking direction side of the upper and lower ends of the protruding side edge of the locking portion is the end of the locking direction side of the upper and lower ends of the restricting portion of the locked portion. The gaming machine according to any one of means 2 to 4, wherein the gaming machine is located on the unlocking direction side from the height position.

  2. Description of the Related Art Conventionally, it is generally configured so that a door can be locked without using a key when the door is locked from an open state to a closed state. For example, the front end of the eaves member tapers in a substantially triangular shape, and when the door body or the like is closed, first, the inclined portion of the eaves member comes into contact with the locked portion. Therefore, by further closing the door or the like, the flange member is displaced in the unlocking direction against the urging force of the urging means such as a coil spring. When the eaves member gets over the locked portion, the eaves member returns to its original position by the urging force of the urging means and is locked to the locked portion. Thereby, locking of a door etc. is completed.

  In the configuration of the means 1 and the like, if a configuration in which the tip of the flange member is tapered in a substantially triangular shape is adopted, when the door body is locked without using a key, the inclined portion of the flange member becomes the locked portion. When the force in the unlocking direction is applied to the collar member, the movement is regulated by the regulating means. For this reason, if the door body is forcibly closed, problems such as deformation or breakage of the flange member or the locked portion may occur.

  On the other hand, according to the means 5, the flange member is always urged to the reference position (locking position) by the urging means, and the locking direction side of the upper and lower end portions of the protruding side edge portion thereof. The height position of the end portion (for example, the lower end portion) is higher than the height position of the end portion (for example, the upper end portion) on the unlocking direction side of the upper and lower end portions of the restricting portion of the locked portion (for example, the locking direction side (for example, The height position of the end (for example, the upper end) on the unlocking direction side of the upper and lower ends of the protruding side edge is the upper and lower ends of the restricting portion of the locked portion. It is located on the unlocking direction side (for example, the upper side) from the height position of the end portion (for example, the lower end portion) on the locking direction side. As a result, when a door body or the like in an open state is closed without using a key, the protruding side edge portion of the flange member and the restricting portion of the locked portion collide so as to come into surface contact. The member does not slide in the unlocking direction, and the door body or the like cannot be closed. In other words, the door body or the like cannot be completely closed unless a normal operation is performed using the key and the heel member is slid and displaced to a position that is not obstructed by the locked portion. As a result, it is possible to suppress the occurrence of problems such as deformation and breakage of the above-described saddle member and the locked portion, and the door body and the like may be closed relatively easily and quickly even when the above-described fraud is performed. Therefore, a store clerk or the like in the game hall can detect the fraud early.

  Means 6. The gaming machine according to any one of means 1 to 5, further comprising a maintaining means for maintaining the saddle member in the reference posture.

  According to the means 6, by providing the maintaining means, at least when the saddle member is interlocked with the movement of the sliding member, the saddle member can be slid while being maintained in the reference posture. For this reason, it is possible to prevent a problem that the eaves member is restricted by the restricting means during the regular unlocking operation performed using the key. On the other hand, when a direct and unauthorized unlocking operation is performed on the collar member, if the collar member rotates against the maintenance force of the maintenance means, the regulation means regulates it. As an example of the maintaining means in the above means 2 etc., “an urging means for urging the flange member (base part) toward the protruding side edge part side of the support part” can be cited as an example.

  In addition, in order to hold | maintain the locked state of a door body etc. more reliably, it is good also as a structure provided with the urging means which urges | biases a collar member etc. to the latching position side. In this case, the heel member is always urged toward the locking position by the urging means, but when there is an appropriate key unlocking operation, the reference posture is maintained by receiving a force from the sliding member. However, it is slid and displaced to the non-locking position. That is, it moves in the unlocking direction by displacing the flange member against the urging force of the urging means. At this time, if the maintaining means of the means 6 and the biasing means of the flange member are embodied in a single biasing member (elastic member such as a coil spring), the increase in the number of parts can be suppressed, and Simplification can be achieved. In addition, for example, the means 3 or the like includes a biasing means that biases the flange member toward the locking position, and a biasing means that biases the engagement member toward the engagement position. Can be maintained at the reference position.

  Mean 7 When the key is not inserted into the locking member, the engaging member of the locking member that engages with the sliding member becomes undisplaceable, and the sliding of the sliding member is restricted by the engaging member. The gaming machine according to any one of means 1 to means 6 characterized by the above.

  According to the means 7, if the key is not inserted into the lock member, the lock state of the lock member is not released, and the sliding member engaged with the engaging member (cam plate or the like) of the locking member cannot slide. As a result, it is possible to prevent an illegal act of illegally unlocking the collar member by illegally sliding the sliding member directly without using a key.

  Means 8. The gaming machine according to any one of means 1 to 7, further comprising a cover member that covers an engaging portion between the lock member and the sliding member and a periphery thereof.

  According to the means 8, it is possible to prevent an illegal act of illegally unlocking the eaves member by illegally sliding the sliding member directly without using a key.

  Conventionally, in order to secure an installation space for a game area, various control boards, and the like, it is necessary to secure the installation space at the position where the lock member is disposed while reducing the overall width of the locking means as much as possible. For this reason, the installation space of a lock member is ensured by forming the bulging part which bulges to a side so that a lock member may be avoided with respect to a sliding member. However, when the bulging portion is formed as described above, a stepped portion is formed between the bulging portion and the sliding member main body at the upper and lower portions of the bulging portion. When the step portion is formed on the sliding member in this way, it becomes possible to slide the sliding member by pressing a metal piece or the like against the step portion. That is, there is a possibility that an unauthorized act of illegally unlocking the eaves member by illegally sliding the sliding member directly without using a key may be performed. On the other hand, if the cover member covers the bulging part (step part) of the sliding member, the illegal act can be prevented.

  The base frame 601 (the attachment plate 602 and the support plate 603) bulges toward the inner side of the inner frame 12 (the window hole 39 side) at a position slightly above the attachment position of the lower flange member 614. This is to secure the installation space at the position where the cylinder lock 700 is disposed while reducing the overall width of the locking device 600 as much as possible in order to secure a wider installation space for the game area and various control boards. It is. Similarly, the sliding rod 610 bulges out at a portion corresponding to the bulging portion of the base frame 601. A pair of upper and lower rectangular engagement holes 621 and 622 that can be engaged with a cam plate 703 of a cylinder lock 700 to be described later are formed in the bulging portion 610a of the sliding rod 610.

  Here, the part relevant to the locking mechanism of the inner frame 12 is demonstrated first. The flange members 613 and 614 constituting the locking mechanism of the inner frame 12 are disposed on the outer side of the inner frame 12 with respect to the sliding rod 610.

  The flange members 613 and 614 include substantially rectangular base portions 613a and 614a overlapping the sliding rod 610, projecting portions 613b and 614b extending rearward from the base portions 613a and 614a along the projecting direction of the support plate 603, and It is comprised from the nail | claw part 613c, 614c which protrudes below from the front-end | tip of protrusion part 613b, 614b. That is, the base portions 613a and 614a are located on the front side (mounting plate 602 side) of the rear edge portion (projecting side edge portion) of the support plate 603, and the projecting portions 613b and 614b and the claw portions 613c and 614c are supported. The plate 603 is located on the rear side (outside of the support portion) from the rear edge portion (projecting side edge portion). Accordingly, the protruding portions 613b and 614b and the claw portions 613c and 614c constitute a locking portion in the present embodiment. With the above configuration, the flange members 613 and 614 have a hook shape in which the portions protruding backward from the support plate 603 (protrusion portions 613b and 614b and claw portions 613c and 614c) are bent downward. Engages with the metal fittings 83 and 84 of the outer frame 11.

  Corresponding to the flange members 613 and 614, inner guide holes 625 and 626 and outer guide holes 627 and 628 are formed in the upper and lower portions of the sliding rod 610 and the support plate 603, respectively. Each guide hole 625 to 628 has an oval shape that is long in the vertical direction. Then, with the guide pins 631 and 632 inserted from the outside of the support plate 603 through the inner guide holes 625 and 626 of the sliding rod 610 and the outer guide holes 627 and 628 of the support plate 603, the flange members 613 and 614 ( It is fixed to the bases 613a, 614a). As a result, the flange members 613 and 614 are engaged with the base frame 601 (support plate 603) and the sliding rod 610 so as to be relatively displaceable in the vertical direction and rotatable. It becomes possible to slide in conjunction with the movement.

  Further, a flange portion that protrudes to the inside (rear side) of the base frame 601 is provided on the outer side edge portion of the inner frame 12 of the mounting plate 602 over the entire length, and the rear edge portion (protruding side edge portion) of the support plate 603 is provided. ) Is provided with a plurality of flange portions projecting to the inside of the base frame 601 (outside the inner frame 12). These flange portions have a function as a guide portion that enhances the stability of the sliding operation of the sliding rod 610, the front frame set locking members 617, 618, 619, and the like, and intrusion of wires or the like into the inside of the base frame 601. And a function of preventing an unauthorized unlocking operation on the sliding rod 610 or the like. Among these, the flange portions 635 and 636 on the support plate 603 side provided at positions corresponding to the flange members 613 and 614 also have a function of guiding the sliding of the flange members 613 and 614. Specifically, slits 635a and 636a are formed in the upper portions of the flange portions 635 and 636. Through the slits 635a and 636a, the protruding portions 613b and 614b of the flange members 613 and 614 protrude rearward from the support plate 603. With such a configuration, the flange members 613 and 614 are slidably held up and down while being guided by the guide pins 631 and 632 and the flange portions 635 and 636.

  The flange members 613 and 614 are urged downward and rearward (to the flange portions 635 and 636 side) by coil springs C1 and C2 as maintaining means and urging means. Specifically, one end of each of the coil springs C1 and C2 is hooked on the hook portions 613d and 614d of the flange members 613 and 614 (base portions 613a and 614a), and the other end is a hook portion provided below the flange portions 635 and 636. 635b and 636b. Accordingly, in the normal state, the flange members 613 and 614 are held at positions where the guide pins 631 and 632 are urged to the lower edge portions of the outer guide holes 627 and 628 of the support plate 603. Therefore, the position where the guide pins 631 and 632 abut on the lower edge portions of the outer guide holes 627 and 628 of the support plate 603 in the sliding range of the flange members 613 and 614 is the locking position (reference) of the flange members 613 and 614. Position). On the other hand, the positions where the guide pins 631 and 632 contact the upper edge portions of the outer guide holes 627 and 628 of the support plate 603 correspond to the non-locking positions of the flange members 613 and 614.

  With the above configuration, when the inner frame 12 is locked, the claw portions 613 c and 614 c of the flange members 613 and 614 are locked to the receiving fittings 83 and 84 fixed to the inner side of the outer frame 11. Opening is restricted (see FIG. 16 and the like).

  Next, parts related to the locking mechanism of the front frame set 14 will be described. As described above, the front frame set locking members 617, 618, 619 constituting the locking mechanism of the front frame set 14 are disposed corresponding to the insertion holes 607, 608, 609 of the mounting plate 602, and 601 can slide along the inside.

  The front frame set locking members 617, 618, 619 are bent in a U-shaped cross section. Among them, rectangular locking holes 617b, 618b, 619b are formed in the mounting side wall portions 617a, 618a, 619a on the mounting plate 602 side.

  The attachment side wall portions 617a, 618a, and 619a are formed with elliptical attachment side guide holes 617c, 618c, and 619c that are long in the vertical direction at positions below the locking holes 617b, 618b, and 619b. Guide pins 641, 642, 643 are fixed to the mounting plate 602 from the inside of the base frame 601 through these mounting side guide holes 617c, 618c, 619c.

  On the other hand, of the front frame set locking members 617, 618, 619, support side guide holes 617e, 618e, 619e that are long in the vertical direction are formed in the support side wall portions 617d, 618d, 619d on the support plate 603 side. Has been. Guide pins 645, 646, and 647 are fixed to the sliding rod 610 from the inside of the base frame 601 through these support side guide holes 617e, 618e, and 619e.

  Each front frame set locking member 617, 618, 619 is urged upward by coil springs C3, C4, C5 as urging means. Specifically, one end of each of the coil springs C3, C4, C5 is hooked on the hook portions 617f, 618f, 619f of the front frame set locking members 617, 618, 619 (support side wall portions 617d, 618d, 619d), and the other end thereof. It is hung on hook portions 651, 652, 653 provided on the mounting plate 602. Thus, in the normal state, the front frame set locking members 617, 618, 619 are located at positions where the lower edge portions of the attachment side guide holes 617c, 618c, 619c are urged by the guide pins 641, 642, 643 of the attachment plate 602. Is retained. At this time, the lower edge portions of the support side guide holes 617e, 618e, and 619e are also urged by the guide pins 645, 646, and 647 of the sliding rod 610. In this state, the locking holes 617b, 618b, 619b are positioned so as to overlap the upper portions of the insertion holes 607, 608, 609 of the mounting plate 602, and the insertion holes 607, 618a, 619a are inserted by the mounting side wall portions 617a, 618a, 619a. The lower portions of 608 and 609 are closed.

  Of the sliding range of the front frame set locking members 617, 618, 619, the position where the lower edge portion of the attachment side guide holes 617c, 618c, 619c abuts on the guide pins 641, 642, 643 of the attachment plate 602 is the front surface. This corresponds to the engagement position (reference position) of the frame set locking members 617, 618, 619. On the other hand, the positions where the upper edge portions of the attachment side guide holes 617c, 618c, 619c abut on the guide pins 641, 642, 643 of the attachment plate 602 are the disengaged positions of the front frame set locking members 617, 618, 619. Equivalent to.

  With the above configuration, when the front frame set 14 is locked, the front frame set collars 14a, 14b, and 14c are inserted through the locking holes 617b, 618b, and 619b of the attachment side wall portions 617a, 618a, and 619a as described above. The mounting side wall portions 617a, 618a, and 619a are locked on the back side, and the opening of the front frame set 14 is restricted.

  Further, the sliding rod 610 is normally held at a position where the lower edge portions of the inner guide holes 625 and 626 are substantially at the same height as the lower edge portions of the outer guide holes 627 and 628 of the support plate 603. . This position corresponds to the reference position of the sliding rod 610. When the sliding rod 610 is in the reference position, the lower edge portion of the inner guide holes 625 and 626 engages with the guide pins 631 and 632 of the flange members 613 and 614, that is, the tensile force of the coil springs C1 and C2. Thus, the upward movement is suppressed, and the guide pins 645, 646, 647 of the sliding rod 610 are engaged with the support side guide holes 617e, 618e, 619e, that is, the coil springs C3, C4. The downward movement is suppressed by the tensile force of C5. And when the cylinder lock 700 mentioned later is operated, it slides and displaces upward or downward against the tensile force of coil spring C1 grade | etc.,.

  Now, a cylinder lock 700 as a lock member is attached to the widened portion (the portion corresponding to the bulging portion) below the attachment plate 602. In the cylinder lock 700, a lock main body portion having a key hole extends forward through the mounting plate 602, and is exposed to the front side of the front frame set 14. On the back side of the cylinder lock 700, a cam plate 703 is provided as an engaging member that transmits the rotation of the key inserted into the keyhole to the sliding rod 610.

  The cam plate 703 includes a pair of upper and lower engaging claws 703a and 703b. The engaging claws 703a and 703b are engaged with the engaging holes 621 and 622 of the sliding rod 610, respectively.

  Note that the cylinder lock 700 of the present embodiment is locked when no key is inserted, and the cam plate 703 cannot be displaced. When the sliding rod 610 is at the reference position, the engaging claws 703a and 703b are both inserted into the engaging holes 621 and 622, and are slid by the cam plate 703 in the locked state. The sliding of the collar 610 is restricted.

  A locking cover 705 as a cover member is attached and fixed to the locking device 600 so as to cover the back side of the cylinder lock 700. The locking cover 705 covers the engaging portion between the cam plate 703 and the sliding rod 610, and also covers substantially the entire bulging portion 610a (including the upper and lower stepped portions) of the sliding rod 610.

  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, the front frame set collars 14a, 14b, 14c are locked to the front frame set locking members 617, 618, 619, and the opening of the front frame set 14 is restricted. .

  When the front frame set 14 is unlocked, the key inserted into the key hole of the cylinder lock 700 is rotated counterclockwise in FIG. As a result, the cam plate 703 rotates in the same direction so that the upper engaging claw 703a contacts the lower edge portion of the upper engaging hole 621 and slides so as to be pushed down by the engaging claw 703a. The collar 610 slides downward.

  When the sliding rod 610 slides downward, the guide pins 645, 646, 647 of the sliding rod 610 push down the lower edge portions of the support side guide holes 617e, 618e, 619e, and the coil springs C3, C4, C5 Front frame set locking members 617, 618, and 619 slide downward against the tensile force. At this time, all front frame set locking members 617, 618, and 619 slide downward simultaneously in conjunction with the sliding rod 610. As a result, the engagement of all the front frame set collars 14a, 14b, 14c and the front frame set locking members 617, 618, 619 is released, and the opening of the front frame set 14 is allowed.

  As described above, when the flange members 613 and 614 are in the locking position (reference position), the guide pins 631 and 632 are engaged with the guide pins 625 and 626 at the upper portion thereof. A space for relative displacement of 631 and the like is secured. For this reason, even when the sliding rod 610 slides downward, the rod members 613 and 614 do not slide and can be maintained as they are.

  On the other hand, when the front frame set 14 is locked, it can be locked without using a key. More specifically, when the front frame set 14 in the open state is closed, the front frame set collars 14a, 14b, 14c are connected to the communication holes 97, 98, 99 of the inner frame 12 and the insertion holes 607, 608 of the mounting plate 602. , 609, 609, 609 b, 619 b, 619 b, are inserted into the locking holes 617 b, 618 b, 619 b of the front frame set locking members 617, 619, 619 b, and the front frame set collars 14 a, 14 b, 14 c are claw portions (inclined portions) attached. It contacts the side wall portions 617a, 618a, 619a. When the front frame set 14 is further closed, the front frame set locking members 617, 618, 619 are pushed downward, and once slide against the tensile force of the coil springs C3, C4, C5. Thereafter, when the claw portions of the front frame set collars 14a, 14b, 14c exceed the front frame set locking members 617, 618, 619, the front frame set locking members 617, 618, 619 returns to its original position and engages with the front frame set collars 14a, 14b, 14c. Thereby, opening of the front frame set 14 is regulated.

  As described above, when the front frame set locking members 617, 618, 619 are in the engagement positions (reference positions), the attachment-side guide holes 617c in which the guide pins 641, 642, 643 of the attachment plate 602 are engaged. Space for the relative displacement of the guide pins 641 and the like is secured in the upper portions of 618c and 619c and in the upper portions of the support side guide holes 617e, 618e and 619e engaged with the guide pins 645, 646 and 647 of the sliding rod 610. Has been. Thereby, even when the front frame set locking members 617, 618, and 619 are slid downward, the sliding rod 610 does not slide in conjunction with this.

  In addition, as described above, each front frame set locking member 617, 618, 619 is configured to be able to slide and displace independently, so that the front frame set locking member 617, Even when an external force is directly applied to any one of 618 and 619, the sliding rod 610 does not interlock with this, so that the other front frame set locking members are not slid and displaced and maintain the engaged position. Will remain.

  Next, locking and unlocking of the inner frame 12 will be described in detail. In the locked state of the inner frame 12, the claw portions 613c and 614c of the flange members 613 and 614 are locked to the receiving brackets 83 and 84 fixed to the inner side of the outer frame 11 as described above, and the inner frame 12 Opening is restricted (see FIG. 16).

  When the inner frame 12 is unlocked, the key inserted into the keyhole of the cylinder lock 700 is rotated in the clockwise direction in FIG. As a result, the cam plate 703 rotates in the same direction so that the lower engagement claw 703b contacts the upper edge of the lower engagement hole 622 and is pushed up by the engagement claw 703b. The sliding rod 610 slides upward.

  When the sliding rod 610 slides upward, the guide pins 631 and 632 are pulled up by the lower edge portions of the inner guide holes 625 and 626 of the sliding rod 610, and the rod member resists the tensile force of the coil springs C1 and C2. 613 and 614 slide upward. At this time, in conjunction with the sliding rod 610, both flange members 613 and 614 slide upward simultaneously. As a result, the engagement between all the flange members 613 and 614 and the metal fittings 83 and 84 is released, and the opening of the inner frame 12 is allowed (see FIG. 17). When the flange members 613 and 614 slide upward, the flange members 613 and 614 are attracted to the flange portions 635 and 636 by the tensile force of the coil springs C1 and C2, and therefore the reference in the locked state. It slides upward while maintaining its posture.

  Further, as described above, when the front frame set locking members 617, 618, 619 are in the engagement positions (reference positions), the front frame set locking members with which the guide pins 645, 646, 647 of the sliding rod 610 are engaged. Spaces in which the guide pins 645 and the like are relatively displaced are secured above the support side guide holes 617e, 618e, 619e of 617, 618, 619. Thus, even when the sliding rod 610 is slid upward, the front frame set locking members 617, 618, 619 are not slid and can be maintained as they are.

  On the other hand, when the inner frame 12 is locked, the present embodiment is configured so that it cannot be locked unless a key is used.

  More specifically, the protruding side edge portions (rear end edge portions) 613h and 614h of the flange members 613 and 614 are formed in a substantially linear shape along the vertical direction from the protruding portions 613b and 614b to the claw portions 613c and 614c. ing.

  On the other hand, the front surface portions 83a and 84a (see FIG. 5) of the receiving fittings 83 and 84 are formed along the vertical direction so that the protruding side edge portions 613h and 614h of the flange members 613 and 614 can come into surface contact. ing. Therefore, the front surface portions 83a and 84a of the metal fittings 83 and 84 constitute a restricting portion in the present embodiment.

  As shown in FIG. 18, when the flange members 613 and 614 are at the reference position, the height of the lower end portions (end portions on the locking direction side) of the protruding side edge portions 613h and 614h of the flange members 613 and 614 is shown. The position T1 is lower (locking direction side) than the height position T2 of the upper ends (ends on the unlocking direction) of the receiving brackets 83 and 84, and the lower ends (ends on the locking direction side) of the receiving fittings 83 and 84 Part) above the height position T3 (unlocking direction side). Further, the height position T4 of the upper end portions (end portions on the unlocking direction side) of the protruding side edge portions 613h and 614h of the flange members 613 and 614 is higher than the height position T2 of the upper end portions of the receiving fittings 83 and 84. It is located above (unlocking direction side).

  For this reason, when the inner frame 12 in the open state is closed without using a key, the protruding side edge portions 613h and 614h of the flange members 613 and 614 and the front surface portions 83a and 84a of the receiving brackets 83 and 84 are connected. The heel members 613 and 614 do not slide upward, and the inner frame 12 cannot be closed.

  Further, the lower side portions of the claw portions 613c and 614c are formed along the substantially horizontal direction at the same height position T1 as the lower end portions of the protruding side edge portions 613h and 614h of the flange members 613 and 614.

  Therefore, when the inner frame 12 is locked, the cylinder lock 700 is operated using a key, and the hook members 613 and 614 are moved to a position where they are not obstructed by the receiving fittings 83 and 84, that is, the unlocked position (see FIG. 17). After the sliding displacement, the claw portions 613c and 614c pass over the receiving fittings 83 and 84 to completely close the inner frame 12, and then the barbs 613 and 614 are returned to the locking position.

  Furthermore, in this embodiment, the structure which prevents the unauthorized unlocking operation with respect to the collar members 613 and 614 is employ | adopted. Hereinafter, the configuration will be described in detail.

  As shown in FIG. 16 and the like, a concave portion 720 is formed at a substantially central portion in the longitudinal direction of the side edge portion (front end edge portion) on the mounting plate 602 side of the base portions 613a and 614a of the flange members 613 and 614.

  The concave portion 720 includes an upper upper concave portion 720a and a lower lower concave portion 720b. The depth of the upper recess 720a is set relatively shallow compared to the lower recess 720b, and gradually becomes deeper as it goes upward.

  By forming the recess 720, the side edges on the mounting plate 602 side of the bases 613 a and 614 a are divided into an upper edge 721 located above the recess 720 and a lower edge 722 located below the recess 720. It is divided. When the flange members 613 and 614 slide, at least one of the upper edge portion 721 and the lower edge portion 722 is in sliding contact with the mounting plate 602 (see FIGS. 16 and 17).

  In addition, a groove 725 serving as a hole serving as a restricting unit is formed in a portion of the mounting plate 602 that faces the upper edge 721 of the flange members 613 and 614 at the locking position.

  As a result, without using a key, a wire rod or the like is hooked on the protruding portions 613b and 614b and the claw portions 613c and 614c of the flange members 613 and 614 at the locking position, and the unlocking direction ( When an upward force is applied, the posture of the flange members 613 and 614 changes from the reference posture in the locked state toward the mounting plate 602 around the guide pins 631 and 632 as shown in FIG. . Then, the upper edge 721 of the bases 613 a and 614 a is inserted into the groove 725. In such a state, even when the external force in the unlocking direction is further applied to the protruding portion 613b and the like and the flange members 613 and 614 try to slide in the unlocking direction, the upper edge 721 of the base portions 613a and 614a Since it catches on the upper edge 725a of the groove 725, the sliding displacement of the flange members 613 and 614 in the unlocking direction is substantially restricted except for the play length of the groove 725. Of course, the play length of the groove 725 is set to such an extent that the claw portions 613c and 614c are not detached from the metal fittings 83 and 84 even when the upper edge portion 721 of the base portions 613a and 614a is in contact with the upper edge portion 725a of the groove 725. Has been.

  In addition, if the vertical length of the groove 725 is too long, the base portions 613a and 614a are fitted into the groove 725 even during the normal sliding operation of the flange members 613 and 614, and an appropriate sliding operation can be performed. In this embodiment, the vertical length of the groove 725 is set to be as short as possible, and the recesses 720 are formed on the side edges of the bases 613a and 614a, so that the desired rotation of the flange members 613 and 614 can be achieved. The amount of movement is secured.

  On the other hand, if the pivoting amount of the flange members 613 and 614 is too large, the claw portions 613c and 614c may be detached from the receiving brackets 83 and 84. Therefore, in this embodiment, the flange members 613 and 614 are attached to the mounting plate 602. When rotated to the side, the bottom of the upper recess 720a is brought into contact with the mounting plate 602 below the groove 725 so that the amount of rotation is minimized. As shown in FIG. 19, the bottom of the upper recess 720a is in surface contact with the mounting plate 602 below the groove 725 because the load of an unauthorized unlocking operation on the flange members 613 and 614 is locally This is to prevent damage and the like.

  The reason why the concave portion 720 is formed in two steps, that is, the upper concave portion 720a and the lower concave portion 720b, is the function of ensuring the desired amount of rotation of the flange members 613 and 614 and the rotation thereof as described above. This is to have a function of regulating Therefore, the depth of the lower recess 720b located on the guide pin 631, 632 side, which is the rotation shaft, is set deeper than the upper recess 720a, and the upper recess 720a is more reliably brought into contact with the mounting plate 602. The lower recess 720 b is not in contact with the mounting plate 602. The reason why the lower end position of the concave portion 720 (lower concave portion 720b) is higher than the guide pins 631 and 632 that are the rotation shafts is to ensure the function of the concave portion 720, while lowering the concave portion 720. This is because a desired length is ensured in the vertical length of the lower edge portion 722 located at the position, and the stability of the sliding operation of the flange members 613 and 614 is enhanced.

  Further, the locking side portions 613j and 614j of the claw portions 613c and 614c are formed in an undercut shape. That is, the latching side portions 613j and 614j are inclined with respect to the vertical direction so that the lower end side is positioned closer to the base frame 601 than the upper end side. If the eaves members 613 and 614 are in the reference posture, the eaves members 613 and 614 are attached to the mounting plate when the locking side portions 613j and 614j of the claw portions 613c and 614c are in a state along the vertical direction. When rotated to the 602 side, the lower ends of the claw portions 613c and 614c are lifted from the back surface portions of the receiving metal fittings 83 and 84, and the claw portions 613c and 614c are easily detached. If the inner frame 12 is forcibly pulled forward in this state, the inner frame 12 may be opened. On the other hand, in this embodiment, when the eaves member 613, 614 is rotated to the mounting plate 602 side by an unauthorized unlocking operation for the eaves member 613, 614, the locking side sides of the claw portions 613c, 614c The portions 613j and 614j are brought into surface contact with the back surfaces of the metal fittings 83 and 84 so that the locked state is secured.

  As described in detail above, when a direct unlocking operation, i.e., an unauthorized unlocking operation, is performed on the scissors members 613 and 614 by a wire or the like without using a key, the posture of the scissors members 613 and 614 is changed. The rotation is changed, and the sliding displacement of the flange members 613 and 614 in the unlocking direction is restricted. Thereby, since the eaves members 613 and 614 are maintained in the locking position, the opening of the inner frame 12 is not allowed. As a result, the defense performance against unauthorized unlocking using a wire or the like is improved.

  In this embodiment, when the flange members 613 and 614 are rotated from the reference posture at the locking position, the upper edge 721 of the base portions 613a and 614a is inserted into the groove 725, so that The sliding displacement in the unlocking direction of the flange members 613 and 614 is restricted at the edge portion 725a. For this reason, it is not necessary to form a useless protruding portion serving as a restricting means, and the front-rear width of the support plate 603 can be reduced as much as possible to prevent the locking device 600 from becoming large. Further, when the flange members 613 and 614 are in the reference posture while the groove 725 is provided, at least one of the upper edge portion 721 and the lower edge portion 722 of the base portions 613a and 614a slides along the mounting plate 602. Since it can move, stability of sliding operation of the eaves members 613 and 614 can be improved.

  In the present embodiment, the inner frame 12 and the front frame set 14 can be unlocked separately while the inner frame 12 and the front frame set 14 can be unlocked separately while the sliding rod 610 is shared. . As a result, the inner frame 12 and the front frame set 14 can be opened separately, improving workability during maintenance and the like, and suppressing an increase in the number of parts. In such a configuration, a configuration in which the flange members 613 and 614 are engaged with the sliding rod 610 so as to move up and down is unavoidable. Therefore, depending on the direct unlocking operation with respect to the flange members 613 and 614, The said defense function which prevents the eaves member 613,614 from moving up and down will become more effective.

  Furthermore, in this embodiment, the protrusion side edge parts 613h and 614h of the flange members 613 and 614 are formed in a substantially linear shape along the vertical direction. When the inner frame 12 in the open state is closed without using a key, the projecting side edge portions 613h and 614h of the flange members 613 and 614 and the front surface portions 83a and 84a of the receiving fittings 83 and 84 face each other. The heel members 613 and 614 do not slide upward so that the inner frame 12 cannot be closed. Therefore, even when the above-described configuration that restricts the sliding displacement of the flange members 613 and 614 in the unlocking direction is employed, the occurrence of problems such as deformation and breakage of the flange members 613 and 614 and the receiving metal parts 83 and 84 is suppressed. Even if a fraudulent act that opens the inner frame 12 is performed, the inner frame 12 is not closed relatively easily and quickly, so that a store clerk or the like in the game hall may detect the fraudulent act early. become able to.

  Further, when the flange members 613 and 614 slide upward, the flange members 613 and 614 are attracted to the flange portions 635 and 636 by the tensile force of the coil springs C1 and C2, and therefore the reference in the locked state. It slides upward while maintaining its posture. For this reason, at the time of the regular unlocking operation performed using a key, the trouble that the movement of the eaves members 613 and 614 is hindered by the groove 725 on the mounting plate 602 side can be prevented.

  Furthermore, since each of the flange members 613 and 614 is configured to slide and displace independently, if any one of the flange members 613 and 614 is slid upward due to an illegal act. However, since the other flange members 613 and 614 do not slide, the locked state of the inner frame 12 is maintained, and the opening is not allowed. As a result, the defense performance against unauthorized unlocking is further improved by a synergistic effect with the above-described configuration that restricts the sliding displacement of the flange members 613 and 614 in the unlocking direction.

  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.

  (D) In the above embodiment, when the flange members 613 and 614 are rotated from the reference posture at the locking position, the upper edge 721 of the base portions 613a and 614a is inserted into the groove 725 as the restricting means. Accordingly, the sliding displacement of the flange members 613 and 614 in the unlocking direction is restricted at the upper edge portion 725a of the groove 725. The restricting means is not limited to the groove 725 in the above embodiment. For example, as the restricting means, a recess may be provided instead of the groove 725, or a protrusion protruding from the mounting plate 602 may be provided. Moreover, in the said embodiment, although the groove | channel 725 used as a control means is formed in the site | part facing the upper edge 721 of the collar members 613 and 614 in a latching position among the attachment plates 602, the control means The formation position is not limited to this, and may be formed in, for example, the flange portions 635 and 636 on the support plate 603 side.
