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.

  In general, a game machine such as a pachislot machine includes a housing and a door. One side portions of the housing and the door are provided so as to be rotatable in the horizontal direction via a hinge. A locking device for locking the door in the closed position is provided between the other side portions of the housing and the door.

  As described in Patent Document 1 below, 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 (second lock members) that are provided so as to be rotatable between a locked position and an unlocked position, and the pair of flange members are connected to the upper and lower ends, respectively. In addition, a movable member that rotates the pair of eaves members by moving up and down is provided. On the other hand, the door-side mounting member is provided with a pair of upper and lower lock members (first 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. On the other hand, when the movable member is moved upward, the pair of hook members rotate 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.

  The movable member is provided with an engaging member. The engagement member can be rotated between the engagement position and the release position. When the engagement member is rotated to the engagement position, the engagement member is engaged with the housing-side mounting member to prevent the movable member from moving upward. The member is prevented from rotating from the engagement position to the release position. This prevents the door from being opened illegally. On the other hand, when the engagement member rotates to the release position, the engagement between the engagement member and the housing-side mounting member is released, and the movable member can move upward. As a result, the collar member can be rotated from the locked position to the unlocked position.

  In addition, an engagement release member is rotatably provided on the housing side attachment member, and a contact portion is provided on the door side attachment member. When the door is rotated to the vicinity of the closed position, the contact portion abuts on the disengagement member. Then, the engagement release member is rotated. Then, the engagement release member hits the engagement member and rotates the engagement member from the engagement position to the release position. As a result, the movable member can move upward. When the door is further rotated, the collar member abuts against the lock member, whereby the door is rotated from the locked position to the unlocked position side. Of course, the movable member is moved upward as the lock member rotates. When the door reaches the closed position, the movable member is moved downward by its own weight or urging means, and the collar member is rotated to the locking position. As a result, the collar member engages with the lock member, and the door is fixed in the closed position.

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 on the other side (the right side in FIG. 1) of the front side of the casing A and the other side of 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.

  The housing side unit 2 has a housing side mounting member (second mounting member) 4. The housing-side mounting member 2 is made of a metal plate 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. . The door side unit 3 has a door side mounting member (first mounting member) 5. The door-side mounting member 5 is formed by bending a metal plate that is long 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 with the opening portion facing the housing A side. In this state, it is fixed to the inner surface of the other side of the back side of the door B.

  As shown in FIGS. 9 and 11, rollers 6 and 6 (first lock members) are fixedly provided at both upper and lower ends of the door-side mounting member 5. When the door B is located at the closed position, the roller 6 is provided so as to be rotatable such that its axis is horizontal and in the left-right direction. The roller 6 may be non-rotatable.

  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 on both ends of the movable plate 7 at the top and bottom, 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 the upper and lower end portions of the housing-side mounting member 4, 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. In addition, the movable plate 7 and the flange member 8 are disposed along one surface of the casing-side mounting member 4 that faces the inner surface of the other side portion of the casing A. 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, an 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 urging means may be moved downward. 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 connected to the middle portion of the movable plate 7 in the longitudinal direction via a shaft 10 extending horizontally in the left-right direction so as to be rotatable in the front-rear direction and not movable in the up-down direction. 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, and the vertical length of the long hole 4b is the movement of the vertical member 8 in the vertical direction. The length is set so as not to limit the range.

  As shown in FIGS. 4, 5, 7, and 8, the engaging member 9 has a defining hole (a defined recess) 9 a. The defining hole 9a may be formed as a hole that does not penetrate the engaging member 9, that is, a recess. The defining hole 9a extends in an arc shape with the shaft 10 as the center. On the other hand, the housing side mounting member 4 is formed with a locking portion 4c that protrudes toward the engaging member 9 side. The locking portion 4c enters the defined hole 9a so as to be relatively movable in the circumferential direction around the shaft 10. Therefore, the engaging member 9 can rotate between a position where the locking portion 4c abuts on one end thereof (the right end portion in FIG. 5) and a position where the locking portion 4c abuts on the other end. The position of the engaging member 9 when the locking portion 4c hits one end of the engaging member 9 is the engaging position, and the engagement when the locking portion 4c hits the other end of the engaging member 9 The position of the member 9 is the release position. The engaging member 9 is a tension coil spring provided between it and the housing-side mounting member 4 (actually, a receiving member 20 fixed to the housing-side mounting member 4; this receiving member 20 will be described later). (Biasing means) 17 is biased in the direction from the release position toward the engagement position.

  The width of the defining hole 9a in the radial direction of the circle centered on the shaft 10 and the length of the locking portion 4c in the same direction are set to be the same. Therefore, when the engagement member 9 is located at the engagement position, the engagement member 9 cannot move in the vertical direction, and the movable plate 7 and the flange member 8 cannot move in the vertical direction. In this state, the movable member 7 and the eaves member 8 are located at the locking position. Therefore, when the movable member 7 and the collar member 8 are located at the locking position and the engagement member 9 is located at the engagement position, the movable member 7 and the collar member 8 are directed from the locking position toward the unlocking position (upward direction). ) As well as down. That is, the position is fixed at the locking position.

  The engaging member 9 is formed with a guide hole (guide recess) 9b. The guide hole 9b may be formed as a hole that does not penetrate the engaging member 9, that is, a recess. The guide hole 9b is disposed on the other end side (release position side) of the defining hole 9a, and extends downward from the lower surface of the defining hole 9a. Moreover, the width of the guide hole 9b is substantially the same as the thickness of the locking portion 4c. Accordingly, when the movable plate 7 moves upward from the locking position toward the unlocking position in a state where the engaging member 9 is located at the release position, the locking portion 4c moves vertically from the defined hole 9a into the guide hole 9b. Enter the movable. The guide hole 9b has a length that allows the movable plate 7 and the flange member 8 to move to the unlocked position. Further, since the width of the guide hole 9b is substantially the same as the thickness of the locking portion 4c, when the locking portion 4c enters the guide hole 9b, the engaging member 9 becomes non-rotatable and is fixed at the release position. The

  As shown in FIGS. 1 and 9 to 17, the door-side unit 3 is provided with an unlocking mechanism for enabling the door B maintained at the closed position by the roller 6 and the flange member 8 to be opened and rotated. It has been. 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. 16, in the cylinder lock 11, the base end surface of the lock shaft 11b in which the key hole 11a is formed is a door so that the key can be operated from the outside even when the door B is in the closed position. B is exposed on the front side. Then, by operating the cylinder lock 11 with a key, the lock shaft 11b is rotated in the arrow A direction from the neutral position to the unlock position shown in FIG. 12, or is rotated in the arrow B direction from the neutral position to the reset position. Can do. 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.

  An unlocking operation plate 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 facing 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 moves 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 13b is the lower surface of the protrusion 9e formed at the upper end of the engagement member 9. Touching. Therefore, when the unlocking operation plate 13 is moved upward from the initial position, the engagement member 9 is first rotated against the biasing force of the coil spring 17 from the engagement position to the release position. When the engagement member 9 is rotated to the release position, it cannot be rotated any further. Thereafter, the engagement member 9 also moves upward as the unlocking operation plate 13 moves upward. 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 movable plate 7 and the flange member 8 are moved downward from the unlocked position to the locked position by their own weight. Accordingly, the unlocking operation plate 13 is moved downward to the initial position. As a result, the locking portion 14c enters the defining hole 9a from the guide hole 9b. Then, the engagement member 9 is rotated from the release position to the engagement position by the coil spring 17.

  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 front lower end portion 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. It is inclined.

  As shown in FIGS. 9 to 17, particularly FIG. 16, the door-side mounting member 5 is provided with a contact roller (contact portion) 19 so as to be rotatable. The contact roller 19 is arranged 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. The contact roller 19 is disposed so as to abut against the inclined surface 9c 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 arrow direction in FIG. 18) (see 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 be rotated any more as a result of the engaging portion 4c striking the other end portion (the right end portion in FIG. 20) of the defining hole 9a. 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 the contact roller 19 hits the inclined surface 9c, the engaging member 9 is rotated and then moved upward, and the inclined surface 9c is used both as a contact portion and a cam portion. Yes.

  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 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. When the roller 6 hits the bottom surface of the lock recess 8a as the hook member 8 moves downward, the movable plate 7 and the hook member 8 reach the locking position and stop. At the same time, the locking portion 4c enters the defined hole 9a from the guide hole 9b. 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). As a result, the movable plate 7 and the eaves member 8 cannot move 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. As a result, the other end of the door B is lifted upward along with the closing rotation. Then, 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.

  In the gaming machine locking device 1 of the present invention, the contact roller 19 directly abuts against the inclined surface 9c of the engaging member 9 without interposing an engagement releasing member. Therefore, the disengagement member is unnecessary, the number of parts can be reduced by that amount, the structure of the locking device 1 can be simplified, and the manufacturing cost can be reduced.

  Since the contact roller 19 is also used as a member for preventing the door B from hanging down in cooperation with the receiving member 20, the member for preventing the door B from hanging down in cooperation with the receiving member 20. Need not be provided separately. Therefore, the number of parts of the locking device 1 can be reduced, and the manufacturing cost can be further reduced.

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 eaves member 9 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.
Further, although the contact roller 19 is used as the contact portion, a contact member in place of the contact roller 19 may be provided on the door side mounting member 5 so as not to rotate. May be provided integrally.
Furthermore, in the above-described embodiment, the locking member 4c is provided in the housing-side mounting member 4, and the defining hole 9a and the guide hole 9b are provided in the engaging member 9. And a specified hole and a guide hole may be provided in the housing-side mounting member 4.
These modifications can be combined as appropriate without departing from the scope of the invention.
