Description

  The present invention relates to a locking device for locking a door of a game machine such as a pachinko machine or a pachislot machine in a closed position.

  Generally, game machines such as pachinko machines and pachislot machines have a housing and a door. The housing and the door are provided such that one side portions thereof can be rotated in the horizontal direction via hinges. A locking device for fixing the door to the closed position is provided between the other side portions of the housing and the door.

  The locking device has a housing-side mounting member that is attached to the housing and a door-side mounting member that is attached to the door. A pair of upper and lower flange members that can rotate between a locked position and an unlocked position, and the pair of flange members are respectively connected to the upper and lower ends and moved up and down to the housing side mounting member. Is provided with a movable member for rotating the pair of eaves members. On the other hand, the door-side mounting member is provided with a pair of upper and lower lock members. When the movable member is moved downward in the state where the door is located at the closed position, the pair of hook members rotate from the unlocked position to the locked position and engage with the pair of lock members, respectively. As a result, the door is fixed in the closed position. Conversely, when the movable member is moved upward, the pair of hook members are rotated from the locked position to the unlocked position, and the engagement of the hook members with the lock member is released. As a result, the door can be rotated from the closed position toward the open position.

  In the locking device having such a configuration, it is possible to switch from the locked state to the unlocked state simply by moving the movable member upward. For this reason, a wire or the like is inserted from the gap between the housing and the door and hooked on the movable member. Then, the door can be opened illegally only by pulling the wire upward and moving the movable member upward.

  Therefore, in the locking device described in Patent Document 1 below, an engaging member is provided on the movable member in order to prevent the movable member from being easily moved upward. The engaging member is provided on the movable member so as to be rotatable between the engaging position and the releasing position and not movable in the vertical direction. When the engaging member is located at the engaging position, the engaging member engages with a locking portion provided on the housing side mounting member so as not to move in the vertical direction. As a result, the movable member becomes immovable in the vertical direction, and the collar member is fixed at the locking position. When the engagement member rotates to the release position, the engagement between the engagement member and the locking portion is released, and the engagement member can move in the vertical direction. As a result, the movable member can move in the vertical direction, and the collar member can be rotated from the locked position to the unlocked position.

  According to the locking device having such an engagement member, the movable member cannot be moved upward unless the engagement member is rotated from the engagement position to the release position, and the hook member is unlocked from the lock position. It cannot be illegally rotated to the position. That is, in order to open the door illegally, a two-stage illegal operation of rotating the engaging member and moving the movable member is necessary. Therefore, the possibility that the door is illegally opened can be reduced.

Japanese Patent No. 3127290

  However, technology to open doors illegally is also becoming increasingly sophisticated. Therefore, there has been a demand for the development of a locking device that can prevent the unauthorized opening operation more reliably.

The present invention has been made to meet the above-mentioned demands, and includes any one of a case of a game machine and a door provided on the case so as to be rotatable in a substantially horizontal direction between a closed position and an open position. A first mounting member provided on one side, a second mounting member provided on the other side, a first locking member provided on the first mounting member, and the first locking member on the second mounting member. The lock position that engages the door and locks the door in the closed position and the first lock member are released, and the door is allowed to rotate from the closed position to the open position. A second lock member provided so as to be displaceable between the lock position and the second mounting member is provided so as to be movable in the vertical direction, and the second lock member is moved from the lock position to the unlock position. When displaced, it moves in the first direction, which is one of the upper and lower directions, and the second lock A movable member connected to the second lock member so as to move in the second direction, which is either the upper or lower direction, when the material is displaced from the unlocked position toward the locked position; And an engagement member provided so as to be rotatable between the release position and the vertical position, and urged to rotate the engagement member from the release position toward the engagement position. Biasing means, and the engaging member includes a longitudinal groove whose longitudinal direction is directed vertically when the engaging member is located at the release position, and one longitudinal end of the longitudinal groove. A lateral groove extending in the lateral direction is formed, and the second mounting member enters the lateral groove when the engagement member is located at the engagement position and moves the engagement member in the first direction. The engagement member is positioned at the release position. In the locking device of the game engaging portion is provided apparatus which allows the movement to the first direction of the engaging member enters the said longitudinal groove when you are, in the first mounting member, and a lock, the lock And an unlocking member that is moved in the first direction from an initial position by an opening operation of the unlocking member, and the unlocking member is configured to rotate the engagement member from the engagement position toward the release position Further, a blocking portion that engages with the engagement member before the locking portion enters the vertical groove from the lateral groove and prevents the engagement member from rotating from a predetermined intermediate position to the release position side. When the unlocking member is located at the initial position, when the engaging member rotates from the engaging position to the intermediate position, the blocking portion engages with the engaging member. From the intermediate position of the engagement member to the release position side When the unlocking member is moved a predetermined distance from the initial position in the first direction, the engagement between the blocking portion and the engaging member is released, and the blocking portion is engaged. The rotation of the member from the engagement position to the release position is allowed .

  According to the present invention having the above-described characteristic configuration, when the engaging member is improperly rotated from the engaging position to the releasing position, when the engaging member is rotated from the engaging position to the intermediate position, the blocking portion is The engagement member is engaged to prevent the engagement member from rotating from the intermediate position to the release position side. Therefore, it is possible to prevent the engaging member from being illegally rotated to the release position and to prevent the door from being illegally opened.

The best mode for carrying out the present invention will be described below with reference to FIGS.
FIG. 1 shows a pachislot machine (game machine) G in which the locking device according to the present invention is used. The pachislot machine G has a housing A and a door B. The casing A has a box shape with an open front surface. The door B has a shallow box shape with an open rear surface. On one side portion (left side portion in FIG. 1) of the front side of the casing A, one side portion on the rear side of the door B is supported so as to be rotatable in a horizontal direction via a hinge (not shown). The door B has a closed position in which the other side portion of the rear surface abuts against the other side portion of the front surface of the casing A and closes the front opening of the casing A, and is separated from the closed position by a predetermined angle (for example, about 110 °). It can be rotated between the open position where the front opening of the housing A is opened.

  Here, in the present invention, unless otherwise specified, the horizontal direction includes not only the true horizontal direction but also a direction inclined by, for example, about 15 ° with respect to the horizontal direction. The vertical direction is the same, and includes not only the vertical direction but also a direction inclined by about 15 ° with respect to the vertical direction. In this embodiment, the rotation axis of the hinge (the rotation axis of the door B) is parallel to the front surface of the housing A, and the front surface of the housing A is slightly inclined so as to fall backward as it goes upward. For example, it is inclined by about 10 °. Therefore, the door B rotates in a direction inclined with respect to the true horizontal direction by an inclination angle of the front surface of the casing A. The front surface of the housing A may be a vertical surface. In that case, the rotation axis of the hinge is directed in the vertical direction, and the door B is rotated in the true horizontal direction.

  A game machine locking device 1 according to the present invention is provided between the other side portion on the front side of the casing A (the right side portion in FIG. 1) and the other side portion on the rear side of the door B. The locking device 1 includes a housing side unit 2 provided on the housing A and a door side unit 3 provided on the door B.

  As shown in FIGS. 1 to 4, the housing unit 2 has a housing mounting member (second mounting member) 4. The housing side mounting member 4 is made of a metal plate material that is long in the vertical direction, and is fixed to the inner surface of the other side portion of the front surface side of the housing A in a state where the longitudinal direction thereof is parallel to the front surface of the housing A. . As shown in FIGS. 1 and 9 to 11, the door-side unit 3 has a door-side attachment member (first attachment member) 5. This door-side mounting member 5 is formed by bending a long metal plate in the vertical direction into a substantially U-shaped cross section, with its longitudinal direction parallel to the back surface of the door B, and the door B positioned at the closed position. The door is fixed to the inner surface of the other side portion of the rear side of the door B so that the opening portion faces the housing A side.

  As shown in FIGS. 9 and 11, rollers 6 and 6 (first lock members) are provided at both upper and lower ends of the door-side mounting member 5 so as to be rotatable and fixed in position. The roller 6 is arranged such that when the door B is located at the closed position, the rotation axis thereof is horizontal and faces the left-right direction. The roller 6 may be provided so as not to rotate.

  As shown in FIGS. 3, 4, and 8, the casing-side mounting member 4 is provided with a movable plate (movable member) 7. The movable plate 7 is made of a long metal plate, and can be moved in the longitudinal direction (vertical direction) of the housing-side mounting member 4 with its longitudinal direction parallel to the longitudinal direction of the housing-side mounting member 2. Is provided. As shown in FIGS. 2 to 4, pins 21 and 21 are provided at both upper and lower ends of the movable plate 7, respectively. The pins 21 and 21 are inserted into long holes 4d provided in the housing side mounting member 4 so as to be movable in the vertical direction. Accordingly, the movable plate 7 is provided on the housing side mounting member 4 so as to be movable in the vertical direction. When the pin 21 hits the lower end of the long hole 4d, the lower limit of movement of the movable plate 7 is determined. The downward movement limit position of the movable plate 7 is set slightly below the locking position described later. When the pin 21 hits the upper end of the long hole 4d, the upper movement limit position of the movable plate 7 is determined. The upper limit position of the movable plate 7 is set slightly above the unlocking position described later.

  One end portions (end portions on the inner side of the casing A) of the flange members (second lock members) 8 and 8 are fixed to both upper and lower end portions of the movable plate 7, respectively. The other end portions (end portions located on the front outer side of the casing A) of the flange members 8 and 8 protrude forward from the window holes 4a and 4a formed at the upper and lower end portions of the housing-side mounting member 4. . A lock recess 8a opened downward is formed at the other end of the flange member 8 protruding forward from the window hole 4a. The movable plate 7 and the eaves member 8 are disposed along one surface of the enclosure side mounting member 4 that faces the inner surface of the other side portion of the enclosure A (the inner surface of the right side portion in FIG. 1). Therefore, the other end portions of the movable plate 7 and the eaves member 8 are covered by the casing A and the enclosure side attachment member 4 and are not visible in FIG. Further, the vertical length of the window hole 4a is set to a length that does not limit the movement limit position of the movable plate 7 in the vertical direction.

  The movable plate 7 and the eaves member 8 can move in the vertical direction, and move downward due to their own weight. Of course, urging means such as a tension coil spring may be provided between the movable plate 7 and the housing side mounting member 4, and the movable plate 7 and the eaves member 8 may be moved downward by this urging means. When the movable plate 7 and the eaves member 8 are moved downward by their own weight, their own weight (gravity) is the moving means, and when the urging means is used, the urging means is the moving means. On the other hand, the movable plate 7 and the eaves member 8 are moved upward by an unlocking operation of a cylinder lock 11 to be described later, or are automatically moved upward by the closing rotation of the door B.

  When the door B is rotated to the closed position with the flange member 8 positioned at the upper movement limit position, the lock recess 8a of the flange member 8 is positioned substantially above the roller 6, and the opening portion of the lock recess 8a. Faces the roller 6. When the collar member 8 is moved downward in this state, the roller 6 relatively enters the lock recess 8a. When the roller 6 hits the upper bottom surface of the lock recess 8a, the flange member 8 can no longer move downward. The position of the collar member 8 (and the movable plate 7) at this time is the locking position. When the eaves member 8 is moved upward by a predetermined distance from the locking position, the entire roller 6 escapes downward from the lock recess 8a. The position of the eaves member 8 at this time is the unlocking position.

  The outer diameter of the roller 6 is set to be substantially the same as the width of the lock recess 8a. Accordingly, when the collar member 8 moves to the locking position and the roller 6 enters the lock recess 8a, the door B cannot be rotated from the closed position toward the open position, and the position is fixed at the closed position. The On the other hand, when the collar member 8 moves from the locked position to the unlocked position, the entire roller 6 comes out of the lock recess 8a, so that the door B can be opened and rotated from the closed position.

  As shown in FIGS. 1-8, the engaging member 9 is arrange | positioned at the other surface (surface which faces the inner side of the housing A; the surface which faces the left side in FIG. 1) of the housing side attachment member 4. As shown in FIG. The engaging member 9 is disposed in the middle portion of the movable plate 7 in the longitudinal direction, and is connected to the shaft 10 extending horizontally in the left-right direction so as to be rotatable in the front-rear direction and immovable in the vertical direction. ing. The shaft 10 passes through a long hole 4b formed in the housing-side mounting member 4 so as to be movable in the vertical direction. The length of the long hole 4b in the vertical direction is that of the movable member 7 (ring member 8). The length is set so as not to limit the range of movement in the vertical direction.

  As shown in FIGS. 5, 7, and 8, the engaging member 9 is formed with a vertical hole (vertical groove) 9 b extending in the vertical direction. The vertical hole 9b is arranged so as to face in the vertical direction when the engaging member 9 is located at the release position. Therefore, when the engagement member 9 is located at the locking position, the vertical hole 9b is inclined with respect to the vertical direction by the rotation angle between the release position of the engagement member 9 and the locking position. . The vertical hole 9b may be formed as a groove on the surface of the engaging member 9 that faces the housing side mounting member 4.

  The engaging member 9 is formed with a lateral hole (lateral groove) 9a. The horizontal hole 9a extends along an arc centered on the axis 10 that is the rotation axis of the engagement member 9, and one end thereof is a side portion on the engagement position side of the upper end portion of the vertical hole 9b (in FIG. 5). Intersects the right side). In other words, the horizontal hole 9a extends in an arc shape around the shaft 10 from the side of the upper end of the vertical hole 9b on the engagement position side. The horizontal hole 9a may be formed as a groove on the surface of the engagement member 9 facing the housing side mounting member 4 in the same manner as the vertical hole 9b.

  A locking portion 4 c that protrudes toward the engaging member 9 is formed on the surface of the housing-side mounting member 4 that faces the engaging member 9. The locking portion 4c is arranged so as to enter the lateral hole 9a when the movable plate 7 is located at the locking position. Moreover, the locking portion 4c is inserted into the lateral hole 9a so as to be relatively movable (relatively rotatable) in the longitudinal direction (arc direction). Therefore, when the engaging member 9 rotates about the shaft 10, the engaging portion 4c relatively moves along the arc along the upper end of the vertical hole 9a and the inside of the horizontal hole 9b. When the engagement member 9 rotates to the engagement position, the locking portion 4c hits the end of the horizontal hole 9b spaced from the vertical hole 9a, and when the engagement member 9 rotates to the release position, the locking portion 4c Of the two side surfaces extending vertically above the vertical hole 9a, it strikes against the side surface spaced from the horizontal hole 9b. In other words, the engagement position of the engagement member 9 is determined by the engagement of the engagement portion 4c with the end portion of the horizontal hole 9b spaced from the longitudinal hole 9a, and the engagement portion 4c extends above and below the longitudinal hole 9a. The release position of the engagement member 9 is determined by striking a side surface that is spaced from the lateral hole 9a of the two side surfaces.

  The vertical length of the locking portion 4c is set to be substantially the same as the vertical width of the lateral hole 9a. Therefore, when the engaging member 9 is located at the engaging position and as a result, the locking portion 4c enters the lateral hole 9a, the locking member 9 is locked to the housing side mounting member 4 so as not to be movable in the vertical direction. The As a result, the movable plate 7 and the flange member 8 are fixed to the locking position. When the engaging member 9 is located at the engaging position, the engaging member 9 cannot be moved in the vertical direction by the locking portion 4c, and the locking portion 4c extends in the longitudinal direction in the lateral hole 9a. If movable, the horizontal hole 9a does not form an arc around the shaft 10 of the engaging member 9, but linearly extends from the vertical hole 9b in the horizontal direction (for example, the direction orthogonal to the vertical hole 9b). You may form so that it may extend.

  The thickness of the locking portion 4c (the thickness in the left-right direction in FIG. 5) is substantially the same as the width of the vertical hole 9b (the width in the left-right direction in FIG. 5), and is relatively moved in the longitudinal direction in the vertical hole 9b. Is possible. Therefore, when the engaging member 9 rotates to the release position and the locking portion 4c enters the vertical hole 9b, the engaging member 9 can move upward (first direction). As a result, the movable plate 7 can move from the locked position to the unlocked position. Of course, the length of the vertical hole 9b is set to a length that does not limit the movement of the movable plate 7 between the locked position and the unlocked position.

  A tension coil spring (biasing means) 17 is provided between the housing side mounting member 4 and the engaging member 9. The coil spring 17 urges the engagement member 9 to rotate counterclockwise in FIG. 5 so that the engagement member 9 rotates from the release position toward the engagement position. Therefore, when the movable plate 7 is positioned at the locking position, the engagement plate 9 is positioned at the engagement position unless an external force is applied to the engagement member 9.

  As shown in FIGS. 1 and 9 to 17, the door side unit 3 is provided with an unlocking mechanism. This unlocking mechanism is for enabling the door B, which is maintained in the closed position by the roller 6 and the flange member 8, to open and rotate, and is configured as follows.

  That is, a cylinder lock 11 as a lock is provided at the middle portion in the vertical direction of the door-side mounting member 5. In particular, as shown in FIG. 12, in the cylinder lock 11, the base end surface of the lock shaft 11b is exposed to the front side of the door B so that the key can be operated from the outside when the door B is in the closed position. The key hole 11a is formed in the base end surface of the lock shaft 11b. Then, by rotating the key inserted into the key hole 11a, the lock shaft 11b is rotated in the arrow A direction from the neutral position to the unlocked position shown in FIG. 12, or in the arrow B direction from the neutral position to the reset position. Can be rotated. The distal end portion of the lock shaft 11b is exposed on the back side of the door B, and the central portion of the operation member 12 having a substantially “<” shape is fixed to the distal end portion. Note that another lock may be used in place of the cylinder lock 11.

  In particular, as shown in FIG. 17, an unlocking operation plate (unlocking member) 13 and a reset plate 14 are provided at an intermediate portion in the vertical direction of the door-side mounting member 5. The unlocking operation plate 13 and the reset plate 14 are arranged in a state in which the door B is directed in the left-right direction when the door B is in the closed position and is opposed to each other. The unlocking operation plate 13 is formed with two guide holes 13a extending vertically. The reset plate 14 is formed with two guide holes 14a extending vertically. And it penetrates one guide hole 13a, 14a so that it can move to an up-down direction, the pin 15 fixed to the door side attachment member 5 and the other guide hole 13a, 14a penetrate to it, and it fixes to the door side attachment member 5. The unlocking operation plate 13 and the reset plate 14 are provided on the door-side attachment member 5 so as to be movable in the vertical direction by the pin 15 thus made.

  A tension coil spring 16 is provided between the unlocking operation plate 13 and the reset plate 14. The unlocking operation plate 13 is biased downward by the biasing force of the tension coil spring 16, and the pin 15 is brought into contact with the upper end portion of the guide hole 13a. At the same time, the reset plate 14 is urged upward, and the pin 15 is brought into contact with the lower end portion of the guide hole 14a. Hereinafter, the position of the unlocking operation plate 13 when the pin 15 is in contact with the upper end portion of the guide hole 13a and the position of the reset plate 14 when the pin 15 is in contact with the lower end portion of the guide hole 14a Is also referred to as the initial position.

  As shown in FIG. 16, the unlocking operation plate 13 has a contact surface 13b facing downward. The abutting surface 13b is in contact with one end portion (lower end portion in FIG. 16) 12a of the operation member 12 when the lock shaft 11b is located at the neutral position. Therefore, when the lock shaft 11b is rotated from the neutral position to the unlock position, the unlock operation plate 13 is moved upward from the initial position.

  At the lower end of the unlocking operation plate 13, an engaging piece 13c that protrudes in the horizontal direction is formed. When the door B is in the closed position and the unlocking operation plate 13 is in the initial position, the upper surface of the engagement piece 13c is a protrusion 9e formed on the upper end of the engagement member 9 (see FIG. 8) or slightly in contact with the lower surface of the lower surface. Therefore, when the unlocking operation plate 13 is moved upward from the initial position, the engaging piece 13c hits the protruding portion 9e, and the engaging member 9 is resisted against the biasing force of the coil spring 17 from the engaging position to the releasing position. And rotate. When the unlocking operation plate 13 is moved upward from the initial position by a predetermined distance (a distance longer by a predetermined length than a later-described release distance), the engagement member 9 is rotated to the release position and further rotated. I can't do that. Moreover, when the engaging member 9 is rotated to the release position, it can move upward. Therefore, when the unlocking operation plate 13 is further moved upward, the engaging member 9 is moved upward along with the upward movement of the unlocking operation plate 13. Thereby, the movable plate 7 and the eaves member 8 are moved from the locking position toward the unlocking position. When the cylinder lock 11 is rotated from the neutral position to the maximum in the direction of arrow A in FIG. 16 and the unlocking operation plate 13 is moved upward from the initial position to the maximum, the movable plate 7 and the flange member 8 are unlocked. To reach. As a result, the engagement of the flange member 8 with the roller 6 is released, and the door B can be opened and rotated from the closed position.

  When the cylinder lock 11 is returned to the neutral position in a state where the movable plate 7 and the flange member 8 are located at the unlocked position, the unlocking operation plate 13 is moved downward to the initial position by the coil spring 16 and the movable plate 7 is moved. And the eaves member 8 is moved downward from the unlocked position to the locked position by its own weight. Accordingly, the engaging member 9 moves downward, so that the locking portion 14c moves relative to the upper end of the vertical hole 9a. Then, the engagement member 9 is rotated from the release position to the engagement position by the coil spring 17. As a result, the movable plate 7 and the flange member 8 are fixed to the locking position.

  The upper surface of the reset plate 14 is in contact with the other end portion (upper end portion in FIG. 16) 12b of the operation member 12. Therefore, when the lock shaft 11b of the cylinder lock 11 is rotated from neutral to the maximum in the direction of arrow B, the reset plate 14 moves downward from the initial position to the reset position against the biasing force of the coil spring 16. Thereby, the interrupted game is resumed. That is, when a sensor (not shown) provided in the housing A detects that the door B is opened and rotated from the closed position by a predetermined angle or more, the game of the pachislot machine G is interrupted based on the detection signal. On the other hand, when the reset plate 14 is moved downward to the reset position, the reset switch 18 provided on the door side attachment member 5 is switched to the ON state. This resumes the game.

  As shown in FIGS. 1 to 8, particularly FIGS. 5 and 7, an inclined surface 9 c is formed at the lower end portion on the front side (right side in FIG. 5) of the engaging member 9. The inclined surface 9c is directed downward as it goes from the front side of the housing A to the back side, even when the engagement member 9 is located at any position between the engagement position and the release position. Inclined.

  As shown in FIGS. 9 to 17, particularly FIGS. 15 to 17, a contact roller 19 is rotatably provided on the door side mounting member 5. The contact roller 19 is disposed so that the axis of the contact roller 19 extends horizontally in the left-right direction when the door B is in the closed position. Moreover, when the door B is closed and rotated from the closed position to a position closer to the front by a predetermined angle (rotated in the direction of the arrow in FIG. 18), the contact roller 19 is tilted. It arrange | positions so that it may contact | abut the surface 9c (refer FIG. 19). When the door B is further closed and rotated in a state where the abutting roller 19 is in contact with the inclined surface 9c, the abutting roller 19 pushes the inclined surface 9c from the front side of the housing A toward the inner side, and the engaging member 9 Is rotated from the engagement position to the release position against the biasing force of the coil spring 17 (see FIG. 20).

  When the engaging member 9 reaches the release position, the engaging portion 4c cannot turn any further as a result of the engaging portion 4c striking against the side surface of the vertical hole 9b (the side surface positioned on the right side in FIG. 20). Accordingly, when the door B is further closed and rotated and the contact roller 19 is moved further to the right in FIG. 20, the inclined surface 9c is pushed upward by the contact roller 19 and the engagement member 9 is moved upward. It is done. As a result, the movable plate 7 and the eaves member 8 are moved from the locking position toward the unlocking position against their own weight. When the uppermost portion of the outer peripheral surface of the contact roller 19 hits the lower end edge of the inclined surface 9c, the movable plate 7 and the flange member 8 have reached the unlocked position.

  As shown in FIG. 5, a holding surface (holding portion) 9 d is provided at the lower end portion of the engaging member 9. The holding surface 9d extends from the lower end edge of the inclined surface 9c toward the back side of the housing A. Therefore, when the door B further rotates after the movable plate 7 and the eaves member 8 reach the unlocked position, the holding surface 9d gets on the contact roller 19. Here, the holding surface 9d is horizontal when the engaging member 9 is located at the release position. Therefore, when the holding surface 9d is on the contact roller 19, the vertical position of the movable plate 7 and the eaves member 8 is constant regardless of the rotational position of the door B, and they are maintained in the unlocked position. The

  When the uppermost portion of the outer peripheral surface of the contact roller 19 passes through the inner end of the holding surface 9d positioned on the front side in the movement direction, the engagement member 9 is moved along with the movement of the contact roller 19. It can move downward. When the engaging member 9 is moved downward and the movable plate 7 and the flange member 8 are moved slightly downward from the unlocked position toward the locked position by their own weight, the lock recess 8a on the lower surface of the flange member 8 is moved accordingly. The part located closer to the door B comes into contact with the outer peripheral surface of the roller 6. For this reason, the engaging member 9, the movable plate 7, and the flange member 8 cannot move any further downward, and are stopped at a fixed position (see FIG. 22).

  When the door B reaches the closed position, the opening of the lock recess 8a of the flange member 8 faces the roller 6 vertically. Moreover, as shown in FIG. 23, the entire contact roller 19 passes through the holding surface 9d. Therefore, the movable plate 7 and the eaves member 8 can move downward, and they move downward due to their own weight. As the collar member 8 moves downward, the roller 6 enters the lock recess 8a. When the roller 6 hits the bottom surface of the lock recess 8a, the movable plate 7 and the flange member 8 reach the locking position and stop. At the same time, the locking portion 4c moves to the upper end of the vertical hole 9b and can enter the horizontal hole 9a. Therefore, the engagement member 9 can be rotated from the release position toward the engagement position, and is rotated to the engagement position by the coil spring 17 (see FIG. 24). When the engaging member 9 rotates to the engaging position, the movable plate 7 and the flange member 8 become immovable in the vertical direction and are fixed at the locking position.

  In order to open and rotate the door B from the closed position, as described above, the cylinder lock 11 is opened (the lock shaft 11b is rotated in the direction of arrow A in FIG. 12). Then, the engagement piece 13c of the unlocking operation plate 13 pushes the lower end of the engagement member 9, that is, the holding surface 9d upward. Thereby, after the engaging member 9 is rotated from the engaging position to the releasing position, the engaging member 9 is moved upward until the movable plate 7 and the flange member 8 reach the unlocked position from the locked position. As a result, the door is unlocked and the door B can be opened and rotated from the closed position.

  As shown in FIGS. 1 to 8, particularly FIGS. 5 and 7, a receiving member (receiving portion) 20 is fixed to the housing-side mounting member 4. The receiving member 20 may be provided integrally with the housing side mounting member 4. The receiving member 20 has an inclined portion 20a and a horizontal portion 20b that are continuous with each other in the front-rear direction. And the receiving member 20 is arrange | positioned so that the inclination part 20a may be located in front of the horizontal part 20b. The inclined portion 20b is inclined so as to form an upward inclination from the near side of the housing A toward the deep side. The horizontal portion 20b extends horizontally from the back end of the inclined portion 20a toward the rear. The horizontal portion 20b is disposed so that the contact roller 19 is in contact with the upper surface of the horizontal portion 20b when the door B is located at the normal closed position. Therefore, if the other end portion of the door B where the door side unit 3 is provided does not hang down with respect to the one end portion rotatably supported by the hinge, the contact roller 19 hits the inclined portion 20a. It just touches the horizontal part 20b.

  However, the other end of the door B often hangs down from one side due to manufacturing errors and deformation of the hinge, deformation of other parts, and the like. For this reason, as shown in FIG. 19, when the door B reaches a position in front of the closed position by a predetermined angle, the contact roller 19 abuts against the inclined portion 20a. In this embodiment, when the inclined surface 9c is pushed upward by the contact roller 19, and as a result, the engaging member 9, the movable plate 7 and the flange member 8 are moved from the locked position to the unlocked position side, The contact roller 19 abuts against the inclined portion 20a. When the contact roller 19 hits the inclined portion 20a, the other end portion of the door B is lifted upward along with the closing rotation. When the door B rotates to the closed position side until the movable plate 7 and the eaves member 8 almost reach the unlocked position, the contact roller 19 rides on the intersection of the inclined portion 20a and the horizontal portion 20b. Then, when the door B further rotates, the contact roller 19 rides on the horizontal portion 20b. The contact roller 19 rides on the horizontal portion 20b even after the door B reaches the closed position. Thereby, it is prevented that the other end part of the door B hangs down with respect to one end part in a closed position, and the whole door B is located in a regular closed position.

  As shown in FIGS. 13, 15, 16 and 17, the unlocking operation plate 13 is provided with a contact protrusion (blocking portion) 13 d. The contact protrusion 13d is located at the engagement position as shown in FIG. 24 when the movable plate 7 and the flange member 8 are located at the locking position and the unlocking operation plate 13 is located at the initial position. The engagement member 9 is spaced apart from the engagement position toward the release position (counterclockwise in FIG. 24), but the engagement member 9 has a predetermined distance from the engagement position toward the release position. When rotated to the intermediate position, as shown in FIG. 25, it is disposed so as to abut against the end on the release position side of the protruding portion 9 e of the engaging member 9. Therefore, the engaging member 9 cannot rotate beyond the intermediate position as long as the movable plate 7 and the flange member 8 are located at the locking position and the unlocking operation plate 13 is located at the initial position. Here, the intermediate position of the engaging member 9 is the relative movement of the locking portion 4c in the horizontal hole 9a toward the vertical hole 9b as the engaging member 9 rotates from the engaging position to the release position side. The position of the engaging member 9 when it moves to the end adjacent to the vertical hole 9b of the horizontal hole 9a.

  Of the two side surfaces extending up and down of the vertical hole 9b, the side surface located on the side of the horizontal hole 9a (the side surface on the left side in FIG. 25) and the two side surfaces extending in the circumferential direction of the horizontal hole 9a A notch (escape portion) 9f is formed at the intersection with the side surface located on the other end side (the side surface located on the lower side in FIG. 25). The notch portion 9f is disposed so as to face the locking portion 4c vertically when the engaging member 9 is rotated to the intermediate position. Moreover, the notch 9f moves the engagement member 9, the movable plate 7 and the flange member 8 upward (in the first direction) by a predetermined release distance in a state where the engagement member 9 is located at the intermediate position. Then, the lower end part of the latching | locking part 4c is formed in the dimension which can enter only the part | minute for cancellation | release distance. Therefore, in a state where the engaging member 9 is rotated to the intermediate position, the engaging member 9, the movable plate 7, and the flange member 8 can move upward by the release distance. The notch portion 9f may have any shape as long as it can accommodate the locking portion 4c when the engagement member 9 moves upward by the release distance. For example, you may form in trapezoid shape so that the width | variety of the left-right direction may become narrow toward the downward direction.

  When the engagement member 9 rotated to the intermediate position is moved upward by the release distance, the contact protrusion 13d moves downward relative to the engagement member 9 as shown in FIG. 26, and the protrusion 9e. Is spaced downward. Therefore, the contact protrusion 13d does not hit the protruding portion 9e, and the engaging member 9 can rotate to the release position beyond the intermediate position. Of course, when the engaging member 9 rotates to the release position, the engaging member 9 can move upward, and the movable plate 7 and the flange member 8 can move upward to the unlocking position. When the engaging member 9 rotated to the intermediate position is moved upward by the release distance, the movable plate 7 and the flange member 8 are moved upward accordingly. However, the release distance is set shorter than the distance between the lock position and the release position. Therefore, before the collar member 8 moves from the locked position to the unlocked position, the engaging member 9 moves by the release distance. Therefore, even if the engagement member 9 is moved upward by the release distance, the engagement between the roller 6 and the flange member 8 is not released, and both maintain the locked state.

  In the above configuration, when the collar member 8 is moved from the locked position to the unlocked position without using the cylinder lock 11, the engaging member 9 is moved from the engaged position to the released position, and then the collar member 8 is moved. Although it is the same as that of the conventional locking device in that it is moved from the locking position to the unlocking position, the locking device 1 cannot rotate the engaging member 9 from the engaging position to the releasing position at once. That is, when the engagement member 9 is rotated from the engagement position to the intermediate position, the contact protrusion 13d abuts against the protrusion 9e of the engagement member 9, and the engagement member 9 rotates from the intermediate position to the release position side. Stop that. In order to further rotate the engagement member 9 to the release position side, it is necessary to move the engagement member 9 together with the movable plate 7 and the flange member 8 upward. When the engagement member 9 is moved upward by the release distance, the contact protrusion 13 moves relatively downward and is separated downward from the protrusion 9e. As a result, the engagement member 9 can be turned to the release position side. Therefore, by maintaining the engaging member 9, the movable plate 7, and the flange member 8 at a position moved upward from the locking position by the releasing distance, the engaging member 9 can be rotated to the releasing position. When the engaging member 9 is rotated to the release position, the movable plate 7 and the flange member 8 can be moved to the unlocked position.

  As described above, in the locking device 1, when the engaging member 9 is rotated from the engaging position to the releasing position, the rotating operation from the engaging position to the intermediate position, the upward movement operation from the locking position, In addition, it is necessary to perform a three-stage operation of turning operation from the intermediate position to the release position. Therefore, the unauthorized rotation with respect to the engaging member 9 can be prevented to a higher degree, and thereby the unauthorized opening operation of the door can be more strictly prevented.

  When the movable plate 7 and the flange member 8 are moved from the locked position to the unlocked position by the cylinder lock 11, the contact protrusion 13d becomes the protrusion 9e when the engaging member 9 rotates from the engaged position to the released position. There is no end to it. When the cylinder lock 11 is unlocked, the unlocking operation plate 13 moves upward from the initial position. At this time, when the release operation plate 13 moves upward from the initial position, it immediately contacts the engagement member 9 and rotates the engagement member 9 from the engagement position to the release position side while moving upward. When the engagement member 9 is rotated from the engagement position to the intermediate position, the unlocking operation plate 13 is moved upward from the initial position by the release distance, and the contact protrusion 13d of the unlocking operation plate 13 is engaged. This is because the contact protrusion 13d is positioned above the protrusion 9e of the combined member 9 and does not hit (engage) the protrusion 9e. Thereafter, when the cylinder lock 11 is further operated to the unlocking position, the engaging member 9 is rotated to the releasing position, and then the engaging member 9 and the movable member 4 are moved upward. As a result, the eaves member 8 moves from the locked position to the unlocked position, and the door B can be opened and rotated. Thus, when the unlocking operation is performed by the cylinder lock 11, the unlocking operation can be performed in the same manner as in the case where the contact protrusion 13d is not formed. In this embodiment, when the unlocking operation plate 13 is moved upward by the release distance, the engagement member 9 is rotated from the engagement position to the intermediate position, and the contact protrusion 13d is moved from the protrusion 9e. Although configured to be separated upward, when the unlocking operation plate 13 moves upward by a predetermined distance different from the release distance, the engagement member 9 rotates from the engagement position to the intermediate position, The contact protrusion 13d may be configured to be spaced upward from the protrusion 9e. However, before the engagement member rotates from the engagement position to the intermediate position, the contact protrusion 13d needs to be configured to be spaced upward from the protrusion 9e.

  Moreover, in the locking device 1 of this embodiment, even when the key of the cylinder lock 11 is lost or not at hand, it can be unlocked with a dedicated unlocking tool (not shown). It can be done. That is, as shown in FIG. 14, a window hole 5 a is formed in the door-side mounting member 5. The window hole 5 a is formed so as to penetrate a wall portion facing the unlocking operation plate 13 of the door side attachment member 5. Then, a key-like engaging portion of a dedicated unlocking tool is inserted through the window hole 5 a and engaged with the unlocking operation plate 13. In this state, the unlocking operation plate 13 can be moved upward by appropriately rotating and tilting the unlocking tool. Accordingly, the engagement member 9 is rotated from the engagement position to the release position in the same manner as when the unlocking operation plate 13 is unlocked by the cylinder lock 11, and then, the movable plate 7 and the flange are moved via the engagement member 9. 8 can be moved from the locked position to the unlocked position.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, the housing side unit 2 of the above embodiment may be provided on the door B, and the door side unit 3 may be provided on the housing A.
In the above embodiment, the hook member 8 is engaged with the roller 6 when the movable plate 7 is moved downward, and the hook member 8 is disengaged from the roller 6 when the movable plate 7 is moved upward. However, the hook member 8 may be engaged with the roller 6 when the movable plate 7 moves upward, and the engagement may be released when the movable plate 7 moves downward. In the case of such a configuration, the lock recess 8 a of the flange member 8 is provided on the upper surface of the flange member 8. Further, biasing means (moving means) such as a tension coil spring is provided between the housing-side mounting member 4 and the movable plate 7, and the movable plate 7 is moved upward by this biasing means to move the flange member 8 to the roller. 6 is engaged. Of course, the contact roller 19 and the inclined surface 9c move the movable plate 7 against the urging force of the urging means.
In the above embodiment, the eaves member 8 is an independent member and is fixed to the movable plate 7, but may be provided integrally with the movable plate 7. The collar member 8 may be rotatably provided on the chassis-side mounting member 4 like the locking device described in Patent Document 1 above. In that case, the movable plate 7 and the flange member 8 are rotatably connected.
Alternatively, the rollers 6 may be fixed to the upper and lower ends of the movable plate 7, and the flange member 8 may be fixed to the door B or the door-side mounting member 5. In this case, the roller 6 is the second lock member, and the flange member 8 is the first lock member.
In the above embodiment, the locking member 4 c is provided on the housing-side mounting member 4, and the horizontal hole 9 a and the vertical hole 9 b are provided on the engaging member 9. A horizontal hole and a vertical hole may be provided in the housing side mounting member 4.
Further, in the above embodiment, the engagement member 9 rotated to the intermediate position is moved upward with respect to the contact protrusion 13d, whereby the engagement state between the engagement member 9 and the contact protrusion 13d is changed. Since the notch 9f is formed in the engagement member 9 because the engagement member 9 is released, the engagement between the engagement member 9 and the contact protrusion 13d is moved by moving the contact protrusion 13d upward or downward. It is also possible to cancel the alignment, and in such a case, it is not necessary to form the notch 9f. When the notch 9f is not formed, the contact protrusion 13d does not necessarily have to contact the engagement member 9 at the intermediate position, and the engagement member 9 is not moved before the engagement member 9 reaches the release position. What is necessary is just to contact | abut. In other words, if the intermediate position where the engaging member 9 abuts against the contact protrusion 13d is a position that is a predetermined angle before the release position, an arbitrary position between the front position and the engaging position (engagement) Including position).
These modifications can be combined as appropriate within a range that does not change the gist of the invention.
