Abstract

PROBLEM TO BE SOLVED: To provide a locking device for further hardly illegally unlocking an opening-closing door.SOLUTION: Respective extension pieces 12 are displaced in the opposite direction, and since a projection 14 of the respective extension pieces 12 is locked by contacting with a different area on the periphery of a fitting object part 120, force for opening the opening-closing door is dispersed to a plurality of areas at least in the fitting object part 120 or its periphery. Thus, in the embodiment, even if large force is added in the direction for opening the opening-closing door, the periphery of the fitting object part 120 is hardly damaged and broken as compared with a constitution for locking by sandwiching one member, and thus, final illegal unlocking of the opening-closing door can be effectively prevented.

Description

  The present invention relates to a locking device that is provided in an opening / closing door that opens and closes an opening formed in a main body of a gaming machine and locks the opening / closing door in a state in which the opening is closed.

  In recent years, as a locking device as described above, a pair of hook members provided on the opening / closing door side is used to realize locking of the opening / closing door by sandwiching an engaging portion of a metal fitting provided on the main body side from two directions. There is what is configured as described above (see Patent Document 1).

  In the locking device with this configuration, in the case of unauthorized unlocking, the hook members in the two directions must be simultaneously displaced in the unlocking direction, and such displacement is performed with a wire inserted through the gap between the main body and the door. This makes it difficult to prevent unauthorized unlocking.

Japanese Patent No. 4094333

  However, in the above configuration, the force when opening the opening / closing door concentrates on one receiving bracket due to the configuration in which one receiving bracket is sandwiched by the flange member from two directions. However, if a large force is applied in the direction of opening the opening / closing door, the receiving metal fitting (and the heel member) is likely to be damaged or broken, which may cause the opening / closing door to be illegally unlocked.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a locking device in which an opening / closing door is more difficult to be illegally unlocked.

  In order to solve the above problems, a first configuration (Claim 1) is provided in an opening / closing door that opens and closes an opening formed in a main body of a gaming machine, and locks the opening / closing door in a state in which the opening is closed. It is a locking device.

  And it consists of a set of extended pieces extending in a positional relationship adjacent to the back side of the door, and each of the extended pieces is inserted into a fitted portion provided on the main body side, Each of the extending pieces is moved until the tip of a protrusion protruding in the opposite direction along the opening surface of the opening portion from the tip side of each extending piece is positioned outside the inner peripheral surface or the inner diameter of the fitted portion. A locking mechanism that realizes locking of the door by preventing displacement of the extension piece from the fitted portion by relatively displacing along the opening surface, and a front side of the door A cylinder lock having a gear that rotates in a forward direction and a reverse direction in response to a locking operation and an unlocking operation of a key fitted in the key hole, and a rack portion that meshes with the gear of the cylinder lock, and through the rack portion For forward and reverse rotation by the gear By moving and moving, an interlocking rod that reciprocates in a direction along the opening surface, and a reciprocating motion by the interlocking rod are transmitted to each of the extending pieces of the locking mechanism. A transmission displacement mechanism that relatively displaces along the opening surface.

In the case of the locking device configured as described above, the extended pieces are relatively displaced, and the protrusions of the extended pieces are locked in contact with different regions of the fitted portion. The force acting between the protruding piece and the fitted portion is distributed at least in a plurality of regions in the fitted portion or its periphery.

  As a result, in the above configuration, even if a large force is applied in the direction of opening the opening / closing door in the locked state, the fitted portion and its surroundings are damaged or broken compared to the configuration in which one member is sandwiched and locked. Therefore, it is possible not only to realize a stable and strong locked state, but also to effectively prevent the door from being illegally unlocked by a large force.

  In addition, in this configuration, each of the pair of extending pieces must be displaced at the same time when the extending pieces are displaced with a wire inserted through a gap between the main body and the opening / closing door, and so on. Since it is difficult to carry out a simple displacement with a wire inserted through a gap, it is also suitable for preventing unauthorized unlocking as described above.

  In the above-described configuration, each of the extended pieces of the locking mechanism is at least from a positional relationship in which it can be inserted into the fitted portion, to a positional relationship in which the detachable state cannot be removed from the fitted portion, What is necessary is just to be able to displace each relatively.

  In the above configuration, the transmission displacement mechanism may be configured to displace only one set of extended pieces in accordance with the locking operation and the unlocking operation of the cylinder lock. It is effective from the viewpoint of preventing unauthorized unlocking that all the extended pieces are displaced.

Therefore, for example, in order to displace two sets of extended pieces at the same time, the above-described configuration may be configured as a second configuration (claim 2) shown below.
In the second configuration, the interlocking rod has a certain length in a direction in which the interlocking rod reciprocates, and a rack portion is formed in a region separated from each of both ends in the length direction by a certain distance. The locking mechanism is arranged in a pair on each end side of the interlocking rod, and the transmission displacement mechanism reciprocates on the end side from each end side of the interlocking rod. And transmitting to the locking mechanism disposed on the end side.

  With this configuration, the locking mechanism can achieve locking at two locations by two sets of extending pieces arranged on both ends of the interlocking rod, and with the increase in the number of extending pieces. Since the unauthorized unlocking that displaces all the extended pieces at the same time becomes more difficult, the effect of preventing unauthorized unlocking is enhanced.

  Further, in the above configuration, the specific configuration of the transmission displacement mechanism is not particularly limited as long as each extended piece that has transmitted the reciprocating motion by the interlocking rod can be relatively displaced along the opening surface. For example, a third configuration (claim 3) described below can be considered.

  In the third configuration, the transmission displacement mechanism is configured such that the transmission displacement mechanism is configured such that one extension piece is connected to the end portion side of the interlocking rod, and the extension piece is reciprocated by the interlocking rod. By following the movement, the extended piece is displaced in the same direction as the interlocking rod, and the other extended piece is connected to the end side of the interlocking rod and connected from the tip of the extended piece. The extension piece is tilted in the opposite direction to the reciprocating motion of the interlocking rod by causing the extending piece to follow the reciprocating motion of the interlocking rod while the region leading to the portion is fixed rotatably. Displace.

  In this configuration, one extension piece is connected to follow the interlocking rod, and the other extension piece is connected to tilt in the opposite direction to the reciprocating motion of the interlocking rod. By only moving in one direction, each extended piece can be displaced simultaneously in the moving direction of the interlocking rod and in the opposite direction.

  Further, in this configuration, each extended piece of the locking mechanism is displaced between at least a positional relationship in which the locking mechanism can be inserted into the fitted portion and a positional relationship in which the locking portion cannot be detached from the fitted portion. The former “positional relationship that allows insertion into the fitted portion” is preferably made to facilitate insertion and removal of the extended piece from the fitted portion.

For this purpose, for example, it is conceivable to make the above configuration as a fourth configuration (claim 4) shown below.
In the fourth configuration, when the other extension piece is projected onto a plane along the displacement direction of the extension piece, the locking mechanism is inserted into the fitted portion in the extension piece. And the tip of the protrusion of each of the extended pieces is fitted to the fitted portion, so that the width of the extending portion is tilted to be equal to or less than the width of the portion inserted into the fitted portion in the one extended piece. Each of the extending pieces is configured to be relatively displaceable along the opening surface between the inner peripheral surface and the positional relationship located outside the inner diameter of the portion.

  With this configuration, the other extension piece tilts and the width of the portion inserted into the fitted portion is equal to or less than the width of the portion inserted into the fitted portion in one extension piece. In the state, the outer diameter of the entire set of extended pieces can be reduced. For this reason, when each of the extended pieces in this state is inserted into and removed from the fitted portion, each of the extended pieces is less likely to contact the fitted portion. Insertion and removal of the protruding piece can be facilitated.

  In each of the above-described configurations, as in a fifth configuration (Claim 5) described below, the interlocking rod is configured so that the tip of the protrusion on each of the extension pieces is fitted to the fitted piece via the transmission displacement mechanism. It is good to be urged | biased in the direction located outside the internal peripheral surface or internal diameter of a part.

  With this configuration, the interlocking rod is biased in the direction in which the tip of the protrusion on each of the extended pieces is positioned outside the inner peripheral surface or inner diameter of the mating portion, so the unlocking operation with the cylinder lock is performed. As long as the extended pieces are not displaced via the interlocking rods, the open / close door can be locked by the extended pieces.

  In each of the above configurations, as in a sixth configuration (Claim 6) described below, the locking mechanism is configured so that each of the extension pieces has a protrusion tip of the extension piece. It is good to be urged | biased by the direction located outside an internal peripheral surface or an internal diameter.

  With this configuration, each extension piece is biased in a direction in which the tip of the protrusion on each extension piece is positioned outside the inner peripheral surface or inner diameter of the fitted portion, so that the unlocking operation by the cylinder lock is performed. As long as the extension pieces are not displaced via the interlocking rods, the doors can be kept locked by the extension pieces.

  Further, in each of the above configurations, the specific configuration of the fitted portion provided on the main body side is not particularly limited as long as a set of extended pieces can be inserted. It is conceivable to form a through hole having a predetermined shape or a slit.

In the latter case, when the fitted portion is a slit, it is conceivable that each of the above-described configurations is made as a seventh configuration (claim 7) shown below.
In the seventh configuration, a pair of columnar members provided in regions corresponding to each of the locking mechanisms on the main body side are arranged at regular intervals in the displacement direction of each of the extending pieces, The space from the columnar member to the other columnar member serves as the fitted portion, and the extended piece is inserted into the fitted portion.

If it is this structure, the extension piece can be inserted here by making into a to-be-fitted part the slit formed as the space from one side of the columnar member to the other.
Note that the columnar member in this configuration may be a circular cylinder with a circular cross section or a polygonal prism with a cross section, but in order to facilitate the passage of the extended piece, it is shown below. The eighth configuration (claim 8) may be used.

In the eighth configuration, each of the columnar members has at least an outer peripheral surface facing the other columnar member formed in a curved surface shape.
If it is this structure, since the outer peripheral surface which each columnar member opposes is a curved surface shape, when an extension piece passes through the space from one side to the other in these columnar members, an extension piece is a columnar member. As a result of reducing the contact area, that is, the resistance when in contact with the outer peripheral surface, the passage can be facilitated.

  In addition, the columnar member in this structure should just be the curved surface shape of each opposing outer peripheral surface, and it uses a cylindrical columnar member as it is, or only uses the outer peripheral surface which opposes in each columnar columnar member as a curved surface. Or you may.

Moreover, about the columnar member mentioned above, it is good for each front-end | tip to be formed in the flange shape like the 9th structure (Claim 9) shown below.
With this configuration, a large force is applied in the direction of opening the open / close door, and even if the columnar member is tilted in the opening direction, the extension piece is caught on the flange-like tip side of the columnar member, and thus is caught. Can be prevented from being illegally unlocked.

  Further, as described above, in order to make it easy for the extending piece to pass between the columnar members, any one of the seventh to ninth configurations described below is a tenth configuration (claim 10). It can be considered as follows.

In the tenth configuration, each of the columnar members is formed in a columnar shape, and a cylindrical sleeve surrounding the columnar region is rotatably attached.
With this configuration, the columnar member has a structure in which a rotatable sleeve is attached to the columnar region. Therefore, when the extending piece passes through the space from one of the columnar members to the other, As a result of the contact resistance in contact with the outer peripheral surface being attenuated by the rotation of the sleeve, the passage can be made even easier.

It is a perspective view which shows the whole locking device. It is a three-plane figure which shows the whole locking device. It is a perspective view which shows a to-be-fitted part and its peripheral region. It is a figure which shows a mode that each extension piece is inserted and locked to a to-be-fitted part. It is a figure which shows the overlapping condition of extension pieces. It is a perspective view which shows a set of columnar member.

Embodiments of the present invention will be described below with reference to the drawings.
(1) Overall Configuration As shown in FIGS. 1 and 2, the locking device 1 is provided on an opening / closing door that opens and closes an opening formed in a main body of a gaming machine (hereinafter simply referred to as “main body”). Is a device that locks the open / close door in a closed state. The lock mechanism 10 includes a pair of extended pieces 12 that extend in an adjacent positional relationship from the back side of the open / close door, and receives an operation of a key fitted in a key hole. The cylinder lock 20 having the rotating gear 22, the interlocking rod 30 that moves in conjunction with the rotation of the gear 22, and the reciprocating motion by the interlocking rod 30 are transmitted to the extension pieces 12 of the locking mechanism 10. The transmission displacement mechanism 40 which relatively displaces 12 along an opening surface is provided.

  Among these, the locking mechanism 10 is arranged in a pair on each end side of the long interlocking rod 30, and each extension piece 12 is a plate-like member that expands along its displacement direction. Yes, each is attached to the elongate casing 2 in an overlapping manner.

  And this locking mechanism 10 is the state which inserted each extended piece 12 in the to-be-fitted part 120 (refer FIG. 3) provided in the main body side, as shown in FIG. Extend until the tip of the protrusion 14 protruding in the opposite direction (upward and downward in FIG. 4) along the opening surface of the opening portion is located outside the inner peripheral surface or inner diameter of the fitted portion 120 from the tip side. By relatively displacing each of the protruding pieces 12 along the opening surface, the extension pieces 12 are prevented from being detached from the fitted portions 120, and the doors are locked (see FIGS. 2B to 2D). c)).

  In other words, the locking mechanism 10 is configured so that each of the extended pieces 12 is at least from a positional relationship in which the extended piece 12 can be inserted into the fitted portion 120 to a positional relationship in which the extended portion 12 cannot be detached from the fitted portion 120. Thus, they can be relatively displaced.

  In addition, the to-be-fitted part 120 should just be formed in the main body side in order to insert the locking mechanism 10, respectively, and in this embodiment, as shown in FIG. 3, the plate-shaped member attached to the main body side 200 has a rectangular through-hole formed in 200. In this case, the fitted parts 120 may be attached to the main body side, each formed on the same plate-like member, or the locking mechanism 10 on the main body side in a state where each is formed on a different plate-like member. It is good also as what attaches to the position corresponding to.

  Further, in the locking mechanism 10, each extending piece 12 is biased in a direction in which the tip of the protrusion 14 in the extending piece 12 is positioned outside the inner peripheral surface or inner diameter of the fitted portion 120. In the present embodiment, the spring 16 is used as the biasing means, but it goes without saying that another biasing means can be used.

The cylinder lock 20 has a keyhole facing the front side of the door, and the gear 22 rotates in the forward direction and the reverse direction in response to the locking and unlocking operations of the key fitted in the keyhole.
Further, the interlocking rod 30 has a rack portion 32 that meshes with the gear 22 of the cylinder lock 20, and the rotation of the gear 22 is caused by the rotation of the gear 22 in a state where the rack portion 32 meshes with the gear 22. It reciprocates in the direction along the opening surface in conjunction with the movement. The interlocking rod 30 is a long member having a certain length in the direction in which the interlocking rod 30 reciprocates, and the rack portion 32 is formed in a region separated from each of both end sides by a certain distance. Has been.

  Further, the interlocking rod 30 is urged through the transmission displacement mechanism 40 in a direction in which the tips of the protrusions 14 of the extended pieces 12 are positioned outside the inner peripheral surface or the inner diameter of the fitted portion 120. . In the present embodiment, the spring 36 is used as the biasing means, but it goes without saying that another biasing means can be used.

Further, the transmission displacement mechanism 40 is provided on each end side of the interlocking rod 30, and transmits the reciprocating motion on each end side to the locking mechanism 10 disposed on this end side.
For example, the transmission displacement mechanism 40 connects the extension piece 12 and the interlocking rod 30 via the connection hole 41 through the connection hole 41 formed in one extension piece 12 along the reciprocating direction. And a connecting pin 43. Therefore, in the state where one extension piece 12 is connected to one end side of the interlocking rod 30, the extension piece 12 is moved in the same direction as the interlocking rod 30 by following the reciprocating motion of the interlocking rod 30. Can be displaced. The connection hole 41 may be formed on one end side of the interlocking rod 30.

  Further, the transmission displacement mechanism 40 has a connecting hole 45 formed in one extending piece 12 along the direction intersecting with the reciprocating motion, and the other extending piece 12 and the interlocking rod 30 through the connecting hole 45. A connecting pin 47 that connects the side (physically one extension piece 12), and a rotating shaft 49 that rotatably fixes a partial region from the tip of the extension piece 12 to the connecting portion. ing. Therefore, in the state where the other extension piece 12 is connected to the other end side of the interlocking rod 30 via the one extension piece 12, the other extension piece 12 is driven by the reciprocating motion of the interlocking rod 30. The protruding piece 12 can be displaced so as to tilt in the opposite direction to the reciprocating motion of the interlocking rod 30.

  Here, the connecting hole 45 is formed on the one extending piece 12 side, and the other extending piece 12 and the interlocking rod 30 are indirectly connected via the one extending piece 12, It is good also as a structure which formed the connection hole 45 in the front end side of the interlocking rod 30, and connected the other extension piece 12 and the interlocking rod 30 directly.

Furthermore, the locking mechanism 10 in the present embodiment is configured so that when the other extending piece 12 is projected onto a plane along the displacement direction of the extending piece 12, as shown in FIG. The positional relationship in which the width of the portion inserted into the fitted portion 120 is tilted so that the width of the portion inserted into the fitted portion 120 is equal to or less than the width of the portion inserted into the fitted portion 120, Each of the extended pieces 12 is configured to be relatively displaceable along the opening surface between the protrusion 14 and the positional relationship where the tip end of the protrusion 14 is located outside the inner peripheral surface or the inner diameter of the fitted portion 120. .
(2) Action and Effect With the locking device 1 according to the above embodiment, the extended pieces 12 are relatively displaced, and the protrusions 14 of the extended pieces 12 come into contact with different regions of the fitted portion 120. Since the locking is performed, the force acting between the extended piece 12 and the fitted portion 120 is dispersed at least in the plurality of regions in the fitted portion 120 or its periphery.

  Thereby, in the said embodiment, even if big force is applied to the direction which opens an opening-and-closing door in the locked state, compared with the structure which pinches and locks one member, the to-be-fitted part 120 and its periphery are damaged. Since it is difficult to break, not only can a stable and strong locked state be realized, but it is also possible to effectively prevent the door from being illegally unlocked by a large force.

  Further, in the above embodiment, when performing the unauthorized unlocking such as displacing the extension piece with a wire inserted from the gap between the main body and the opening and closing door, each set of extension pieces 12 must be simultaneously displaced, Since it is difficult to carry out such a displacement with a wire inserted through a gap, it is also suitable for preventing unauthorized unlocking as described above.

  Moreover, in the said embodiment, the locking mechanism 10 can implement | achieve locking in two places with the two sets of extended pieces 12 arrange | positioned at the both ends of the interlocking | linkage rod 30, and the extended pieces 12 are As the number increases, unauthorized unlocking that displaces all the extended pieces 12 at the same time becomes more difficult, and the effect of preventing unauthorized unlocking is enhanced.

  Moreover, in the said embodiment, one extension piece 12 is connected so that the interlocking rod 30 may follow, and the other extension piece 12 is connected so that it may incline in the opposite direction to the reciprocating motion of the interlocking rod 30. Therefore, the extension piece 12 can be displaced simultaneously in the moving direction of the interlocking rod 30 and the opposite direction by only moving the interlocking rod 30 in one direction.

Moreover, in the said embodiment, the other extension piece 12 inclines and the width | variety of the part inserted in the to-be-fitted part 120 is below the width | variety of the part inserted in the to-be-fitted part 120 in one extension piece 12. Therefore, in this state, the outer diameter of the set of extended pieces 12 as a whole can be reduced. Therefore, when each of the extended pieces 12 in this state is inserted into and removed from the fitted portion 120, each of the extended pieces 12 is less likely to contact the inner peripheral surface of the fitted portion 120. The extension piece 12 can be easily inserted into and removed from the joint portion 120.

  Further, in the above embodiment, the interlocking rod 30 is biased in the direction in which the tip of the protrusion 14 in each of the extended pieces 12 is positioned outside the inner diameter of the fitted portion 120, so that the unlocking by the cylinder lock 20 is performed. Unless each of the extended pieces 12 is displaced via the interlocking rod 30 by performing a locking operation, the open / close door can be kept locked by each of the extended pieces 12.

In the above embodiment, each of the extending pieces 12 is urged in a direction in which the tip of the protrusion 14 of each extending piece 12 is located outside the inner diameter of the fitted portion 120, so that the cylinder lock 20 As long as the unlocking operation is not performed and the extended pieces 12 are displaced via the interlocking rod 30, the doors can be kept locked by the extended pieces 12, respectively.
(3) Modifications Embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the above-described embodiment, the transmission displacement mechanism 40 is provided so as to displace the two sets of extending pieces 12 in accordance with the locking operation and the unlocking operation of the cylinder lock 20, but three or more sets of extension mechanisms 12 are provided. The protruding piece 12 may be provided so as to be displaced.

  Moreover, in the said embodiment, the structure to which the to-be-fitted part 120 has the through-hole formed in the plate-shaped member 200 was illustrated. However, the specific configuration of the fitted portion 120 is not particularly limited as long as a set of extended pieces 12 can be inserted. For example, the fitted portion 120 may be formed as a slit on the main body side.

  As described above, when the fitted portion 120 is a slit, a pair of columnar members 50 provided in regions corresponding to the respective locking mechanisms 10 on the main body side are extended as shown in FIG. It is assumed that the protruding pieces 12 are arranged at a certain interval in the displacement direction, and the extending piece 12 is inserted with the slit formed as a space from one side of the columnar member 50 to the other set as the fitted portion 120. It is good as well.

  Here, the columnar member 50 in this configuration may be a circular cylinder with a circular cross section or a polygonal prism with a cross section, but in order to facilitate the passage of the extended piece, a columnar member Each of the members 50 may have a curved outer peripheral surface that faces at least the other columnar member 50.

  If it is this structure, since the outer peripheral surface which each columnar member 50 opposes is a curved surface shape, when the extended piece 12 passes through the space from one side of these columnar members 50 to the other, the extended piece 12 As a result, the contact area, that is, the resistance when the contact with the outer peripheral surface of the columnar member 50 is reduced, the passage thereof can be facilitated.

  The columnar members 50 in this configuration only have to have curved outer peripheral surfaces that face each other. The cylindrical columnar members 50 are used as they are, or only the opposed outer circumferential surfaces of the prismatic columnar members 50 are curved. It may be used as a shape.

Moreover, as for the columnar member 50 mentioned above, as shown in FIG.6 (b), it is good that the flange 52 is formed in each front-end | tip.
In this case, even if a large force is applied in the opening direction of the opening / closing door and the columnar member 50 is tilted in the opening direction, the extension piece 12 is caught by the flange 52 in the columnar member 50, and thus is caught. Therefore, it is possible to prevent unauthorized unlocking.

  Furthermore, in order to make it easy for the extending piece 12 to pass between the columnar members 50 as described above, as shown in FIG. 6 (c), each columnar member 50 is formed in a columnar shape. A configuration in which a cylindrical sleeve 54 surrounding a columnar region is rotatably attached is conceivable.

  With this configuration, the columnar member 50 has a structure in which a rotatable sleeve 54 is attached to a column. Therefore, when the extending piece 12 passes through a space from one of the columnar members 50 to the other, the columnar member 50 As a result of the contact resistance in contact with the outer peripheral surface of the member 50 being attenuated by the rotation of the sleeve 54, the passage can be made even easier.

  In addition, about the structure regarding the columnar member 50 mentioned above, it may be provided with both the flange 52 and the sleeve 54, and the flange 52 of each columnar member 50 may be connected.

The first configuration for solving the above problems, provided the opening and closing door for opening and closing the opening portion formed in the main body of the gaming machine, is a locking device for locking the door in the closed state of the opening portion .

Therefore, for example, in order to simultaneously displace the two sets of the extending piece, it may be like the second configuration shown below the structure.
In the second configuration, the interlocking rod has a certain length in a direction in which the interlocking rod reciprocates, and a rack portion is formed in a region separated from each of both ends in the length direction by a certain distance. The locking mechanism is arranged in a pair on each end side of the interlocking rod, and the transmission displacement mechanism reciprocates on the end side from each end side of the interlocking rod. And transmitting to the locking mechanism disposed on the end side.

Further, in the above configuration, the specific configuration of the transmission displacement mechanism is not particularly limited as long as each extended piece that has transmitted the reciprocating motion by the interlocking rod can be relatively displaced along the opening surface. for example, it is conceivable to a third as configuration shown below.

For this purpose, for example, it is conceivable to make the fourth configuration shown below the structure.
In the fourth configuration, when the other extension piece is projected onto a plane along the displacement direction of the extension piece, the locking mechanism is inserted into the fitted portion in the extension piece. And the tip of the protrusion of each of the extended pieces is fitted to the fitted portion, so that the width of the extending portion is tilted to be equal to or less than the width of the portion inserted into the fitted portion in the one extended piece. Each of the extending pieces is configured to be relatively displaceable along the opening surface between the inner peripheral surface and the positional relationship located outside the inner diameter of the portion.

Further, in the above structure, as in the fifth configuration shown below, the interlocking rod through the transmission displacement mechanism, the inner periphery of the tips of the projections in the extension piece each of the fitted portion It is good to be urged | biased in the direction located outside a surface or an internal diameter.

Further, in the above structure, as in the sixth configuration described below, the locking mechanism, each of said extending piece is an inner peripheral surface of the tip of the projection in said extension piece fitted portion or It is good to be urged | biased in the direction located outside an internal diameter.

This latter way, when the slit of the fitted portion, it is conceivable to make the seventh configuration shown below each structure.
In the seventh configuration, a pair of columnar members provided in regions corresponding to each of the locking mechanisms on the main body side are arranged at regular intervals in the displacement direction of each of the extending pieces, The space from the columnar member to the other columnar member serves as the fitted portion, and the extended piece is inserted into the fitted portion.

If it is this structure, the extension piece can be inserted here by making into a to-be-fitted part the slit formed as the space from one side of the columnar member to the other.
Note that the columnar member in this configuration may be a circular cylinder with a circular cross section or a polygonal prism with a cross section, but in order to facilitate the passage of the extended piece, it is shown below. it may be like configuration of the eighth.

As for the columnar member described above, as in the ninth configuration shown below, each of the tip is formed in a flange shape, and good.
With this configuration, a large force is applied in the direction of opening the open / close door, and even if the columnar member is tilted in the opening direction, the extension piece is caught on the flange-like tip side of the columnar member, and thus is caught. Can be prevented from being illegally unlocked.

As described above, in order to makes it easier to strip extending between the columnar member passes, so that the tenth configuration below any configuration of the first 7-9 It is possible.
