  By the way, the patent document 1 does not disclose any specific means for locking the door body. In this type of flexible platform door device, it is required that the doors in the closed position are not manually opened by passengers on the platform, and the doors in the open position are also manually moved. It is required to hold the passengers securely so that the passengers do not collide and move. Furthermore, it is necessary to prevent the door body from being opened where it does not correspond to the boarding / alighting passage. However, since there are a plurality of opening / closing patterns of the door body, the opening position of each door body also has a plurality of patterns. Therefore, in order to prevent the door body from being moved by manual operation or the like at both the closed position and the opening position, the door There is a problem that the mechanism for locking the body becomes complicated. In particular, it is very labor intensive to design a lock device for each door position according to the platform to be installed. On the other hand, although it is possible to prevent the door body from moving by manual operation etc. by adopting a configuration that applies electromagnetic braking to the motor that drives the door body, in such a configuration, the door body moves. This is not preferable from the viewpoint of locking securely.

  Therefore, the present invention has been made in view of such a point, and the object of the present invention is to prevent the door from being configured to lock the door constituting the flexible home door device from being complicated. The purpose is to secure the body lock.

In order to achieve the above object, the present invention is based on the assumption that a flexible platform door device is provided with a large number of doors connected on a platform and configured to open a boarding / alighting passage according to an incoming train. A long member which is arranged in a posture extending along the opening and closing direction of the door body, and is provided with a large number of fixed side engaging portions arranged in the lengthwise direction and configured by a rack; and the fixed side engaging portion; has a movable side engagement portion having an engagement shape capable, the provided so as to move in the closing direction together with the door body for each door body, a number that will be constituted by a pinion meshing with the rack And the locked state where the movable side engaging portion is locked by the fixed side engaging portion to lock the door body, and the locked state. By canceling Comprising a switching means for switching between an unlocked state to unlock Kitobiratai, and a braking means for the pinion braked so as not to rotate, the switching means, actuating said braking means By doing so, it is configured to switch between the locked state and the unlocked state, and each door body is rotatably provided with a door wheel that rolls along a rail body superimposed on the back surface of the rack. A door hanger and a drive motor fixed to the door hanger are provided, and each pinion is provided on a drive shaft of the drive motor, and the rail body and the rack are sandwiched between the pinion and the door wheel. Has been.

  In this invention, since the fixed side engaging part for locking the movable side engaging part is provided in large numbers along the opening and closing direction of the door body, the fixed side engaging part in which the movable side engaging part is locked is provided. The door body can be held so as not to open and close at a position corresponding to the portion. For this reason, in a flexible home door device in which there are multiple door body opening / closing patterns and the door body is locked in multiple positions, the lock device for each door body is designed exclusively for the platform to be installed. Even without this, the door can be locked at an appropriate position. In addition, since the long member having a large number of fixed-side engaging portions is simply disposed so as to extend along the opening and closing direction of the door body, it is possible to prevent the device configuration for locking the door body from becoming complicated. . Further, since the door body is mechanically locked by locking the movable side member and the long member, the door body can be reliably locked.

And when it is braked so that the pinion does not rotate, even if the door body is pressed in the opening and closing direction, the pinion is locked to the rack, so that the door body can be reliably locked. . In addition, since the pinion teeth and the rack teeth are engaged regardless of the position of the door body, the door position when locking the door body can be arbitrarily set. For this reason, not only can the door body be locked at a desired position, but also the door body can be securely held so as not to move by the mechanical lock between the rack and the pinion.

Further , since the pinion is driven by the drive motor and moves along the rack while meshing with the rack, an opening / closing driving force is applied to the door body. In other words, the rack and pinion as the door body locking device can be shared with the rack and pinion as the door body driving means. Therefore, the number of parts can be reduced, and the configuration can be further prevented from becoming complicated.

Furthermore , since the rail body and the rack are sandwiched between the pinion and the door pulley, the door hanger can be made difficult to swing in the thickness direction of the door body. Thereby, interference of door bodies can be avoided and it can be smoothly opened and closed.

  As described above, according to the present invention, it is possible to secure locking while suppressing the complexity of the configuration for locking the door body.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  Here, the configuration of the control system of the home door apparatus 10 will be described. As shown in FIG. 4, the platform door device 10 is provided with a centralized controller 64, and the central body 64 is connected to each door body 11 (12, 13) via a power line 65 and a signal line 66. The door unit 69 corresponding to is electrically connected.

  The centralized controller 64 is configured to output a door open command and a door close command that specify the corresponding door unit 69 in order to open and close the boarding / alighting passage according to the train organization of the train to be entered.

  Each door unit 69 controls driving of the corresponding door body 11 (12, 13), and includes a serial interface 70, the motor controller 54 (55, 56), and the drive motor 49 (50, 51). It has.

  The serial interface 70 is electrically connected to the power supply line 65 and the signal line 66 via the trolley 72, respectively.

  The motor controller 54 (55, 56) communicates with the centralized controller 64 via the serial interface 70, and performs drive control of the drive motor 49 (50, 51) based on the signal received from the centralized controller 64. It is configured.

  As schematically shown in FIG. 4, the pinion 59 (60, 61) is coupled to the drive shaft of the drive motor 49 (50, 51) with an electromagnetic brake 74 and a speed reducer 75 interposed therebetween. Yes.

  The electromagnetic brake 74 is for braking the drive motor 49 (50, 51), and constitutes a braking means for braking so that the pinion 59 (60, 61) does not rotate. The electromagnetic brake 74 is electrically connected to the signal line 66 and brakes the drive motor 49 (50, 51) in an unexcited state, while the signal from the centralized controller 64 is input and excited. In addition, the brake of the drive motor 49 (50, 51) is released. In a state where the drive motor 49 (50, 51) is braked, the pinion 59 (60, 61) is locked so as not to rotate. In this state, the tooth portion 59a (60a, 60a, 60n) of the pinion 59 (60, 61) is locked. 61a) is engaged with the teeth 34a (35a, 36a) of the rack 34 (35, 36), and the door 11 (12, 13) is locked. On the other hand, by releasing the braking of the drive motor 49 (50, 51), the unlocked state is established.

  The central controller 64 functionally includes a switching means 78 that switches between the locked state and the unlocked state for each door 11 (12, 13). The switching means 78 specifies an opening command for opening the door 11 (12, 13), a closing command for closing the door 11 (12, 13), and a door 11 (12, 13) for opening / closing. To output door number information. The opening command or the closing command includes information related to the driving direction of the motor and information related to the driving amount, that is, the movement amount of the door body 11 (12, 13).

  Each door unit 69 is configured to accept an open command or a close command when the received door number information matches a door number stored in advance. When these commands are accepted, the electromagnetic brake 74 is switched between excitation and non-excitation, and the drive control of the drive motor 49 (50, 51) is executed to open and close the door body 11 (12, 13). Is done.

  Next, the operation of the home door apparatus 10 will be described.

  In a normal time when the train is not connected, as shown in FIG. 1, all the door bodies 11, 12, 13 are in a closed state in the closed position, and the boarding / alighting passage is closed. In this state, the electromagnetic brakes 74 of the door units 69 are all in a non-excited state and are locked with the pinions 59, 60, 61 being braked. Even if customers try to open it manually, it will not open. Thereby, the passenger of a platform cannot go out to the track side, and the safety of the passenger is ensured.

  Hereinafter, the control operation in each door unit 69 will be described with reference to FIG.

  Each door unit 69 determines whether or not a command from the centralized controller 64 has been received (step S1), and when the train enters the line and opens the passenger door, the door body that opens from the centralized controller 64 is operated. An opening command specifying 11, 12, 13 is issued, and when the boarding / exiting door is closed after closing, the central controller 64 issues a closing command specifying the door body 11, 12, 13 that performs the closing operation. In each door unit 69, when the command is received, the door number of the command is confirmed (step S2), and when the door number matches the own door number, the process proceeds to step S3.

  In step S3, it is determined whether or not it is an opening command for opening in the right direction. If the determination is YES, the process proceeds to step S4 to release the lock. That is, by exciting the electromagnetic brake 74 of the door unit 69, the braking of the pinions 59, 60, 61 is released. When the pinions 59, 60, 61 are driven by the drive motors 49, 50, 51, the tooth portions 59a, 60a, 61a of the pinions 59, 60, 61 are replaced with the tooth portions 34a, 35a, For example, when the door body 11, 12, 13 is rotated forward while meshing with the door 36 a, the door body 44, 45, 46 rolls along the rail body 29, 30, 31 and the door body 11, 12, 13 opens and operates (step S5). At this time, the door bodies 11, 12, and 13 are moved by the distance specified by the opening command and become the open position. When the opening operation up to this opening position is completed, the door bodies 11, 12, 13 are locked (step S6). That is, the brakes are applied to the drive shafts of the drive motors 49, 50, 51 by deactivating the electromagnetic brake 74 of the door unit 69. As a result, even if the door bodies 11, 12, 13 are moved manually, the pinions 59, 60, 61 are locked to the racks 34, 35, 36, so that the door bodies 11, 12, 13 are mechanically locked. Will be.

  On the other hand, when the determination in step S3 is NO, the process proceeds to step S10. In this step S10, it is determined whether or not the command transmitted from the centralized controller 64 is an open command for opening in the left direction. If the determination is YES, the process proceeds to step S11. Steps S11 to S13 are the same as Steps S4 to S6 except that the opening direction is reversed left and right, that is, the rotation directions of the pinions 59, 60, and 61 are reversed.

  If the determination in step S10 is no, the process proceeds to step S20. In this step S20, it is determined whether or not the command transmitted from the centralized controller 64 is a closing command for performing a closing operation. If the determination is YES, the process proceeds to step S21. In step S21, the electromagnetic brake 74 is released, and in step S22, a closing operation for moving the door bodies 11, 12, and 13 to the closed position is performed. When the closing operation is finished, the door bodies 11, 12, 13 are locked in step S23.

  An example of the movement at the time of opening and closing of the door bodies 11, 12, and 13 according to the above flow will be schematically described. For example, when the entrance passage is opened at the position A shown in FIG. 11 moves leftward by one door body, and the right first door body 11 moves rightward by one door body. Further, when opening the entrance / exit passage at position B, the second door body 12 on the left side moves leftward by one door body, and the pair of first door bodies 11 and 11 together moves rightward. Each moves one door. Further, when the entrance / exit passage is opened at the position C, the left third door body 13 moves together with the left third door body by one door body in the left direction, while the left second door body 13 moves. The door 12 moves to the right by one door. Thus, the various door bodies 11, 12, and 13 move to the left and right according to the getting-on / off passage, so that the getting-on / off passage according to the vehicle formation is opened.

  As described above, according to the present embodiment, when braking is performed so that the pinions 59, 60, 61 do not rotate, even if the door bodies 11, 12, 13 are pressed in the opening / closing direction, Since the door bodies 11, 12, 13 are mechanically locked by the pinions 59, 60, 61 being locked to the racks 34, 35, 36, the door bodies 11, 12, 13 can be opened and closed. It can be surely prevented. Moreover, since the pinions 59, 60, 61 can be locked without selecting the positions of the door bodies 11, 12, 13, the door positions when the door bodies 11, 12, 13 are locked can be arbitrarily set. Can be set. For this reason, it becomes possible to lock the door bodies 11, 12, 13 at a desired position, the length of the platform on which the home door device 10 is installed, the number of door bodies 11, 12, 13, the door bodies 11, 12, The door bodies 11, 12, and 13 can be locked at an appropriate position without individually designing a locking device in accordance with the size of 13 or the like. In addition, since the racks 34, 35, and 36 are merely arranged so as to extend along the opening and closing direction of the door bodies 11, 12, and 13, the configuration of the lock device for the door bodies 11, 12, and 13 is prevented from becoming complicated. can do. As a result, not only can the locking be ensured, but the versatility of the platform door device 10 can be significantly improved while suppressing the complexity of the device configuration.

  Further, in the present embodiment, the pinions 59, 60, 61 are provided on the drive shafts of the drive motors 49, 50, 51 for driving the door bodies 11, 12, 13, so that the door bodies 11, 12, 13 are locked. The rack and pinion as the device can be shared with the rack and pinion as the driving means for the door bodies 11, 12, and 13. As a result, the number of parts can be reduced and the configuration can be further prevented from becoming complicated.

  Moreover, in this embodiment, since the rail bodies 29, 30, 31 and the racks 34, 35, 36 are sandwiched between the pinions 59, 60, 61 and the door wheels 44, 45, 46, the door hangers 39, 40, 41 are It is possible to make it difficult for the door bodies 11, 12, and 13 to swing in the thickness direction. Thereby, the interference of door bodies 11, 12, and 13 can be avoided, and the doors can be smoothly opened and closed.

In the present embodiment, the locking device for the door bodies 11, 12, and 13 is a rack and pinion system . As shown in FIG. 6, the locking device according to the reference example includes a long member 80 having a large number of convex portions 82 and a movable side member 86 having a rod member 84 that can be engaged between the adjacent convex portions 82. with Ru.

  That is, the long member 80 is provided with a large number of convex portions 82 projecting downward at intervals in the length direction. And the drive motor 49 (50, 51) of each door body 11 (12, 13) is comprised so that the door wheel 44 (45, 46) provided in one door hanger 39 (40, 41) may be driven directly. The other door hanger 39 (40, 41) is provided with a movable side member 86 for moving the rod member 84 forward and backward. The movable member 86 moves the rod member 84 up and down by performing electromagnetic switching. In other words, the movable side member 86 is positioned at a lock position where the rod member 84 engages with the convex portion 82 of the long member 80 in the non-excited state, and the rod member 84 descends in the excited state, and the adjacent convex portion 82. It is positioned at the release position where it leaves.

In this reference example , since the rod member 84 is locked to the convex portion 82 of the long member 80 and the door body 11 (12, 13) is mechanically locked, the door body 11 (12, 13). Opening and closing movements can be reliably prevented. Moreover, since a large number of convex portions 82 are arranged in the length direction of the long member 80, the door body position when the door body 11 (12, 13) is locked can be arbitrarily set, The door 11 (12, 13) can be locked at a desired position. In addition, it is good also as a structure which replaces with the structure which provides the convex part 82 in the elongate member 80, and has formed many through-holes in the elongate member, and a rod member penetrates into this through-hole.
