Description

The present invention relates to a door system including a pair of sliding doors used in a train or the like, and more particularly to a door system capable of handling a foreign object or the like caught between the sliding doors.

Conventionally, in electric trains and the like, a door system (door closing device) that switches between a closed state and an open state by contacting and separating a pair of sliding doors from each other has been used. As such a door system, there is a linear motor system in which a motor is provided for each sliding door, an FPCM (Flat Cup Permanent Magnet Motor) system in which both sliding doors are opened and closed by one motor, and the like.

FIG. 8A (a) is a diagram showing a fully closed state of the linear motor type door system 800 according to the conventional technique, and FIG. 8A (b) shows a fully open state of the linear motor type door system 800 according to the conventional technique. It is a figure which shows. In the door system 800, linear motors 820a and 820b are provided on the left door 810a and the right door 810b (toward the drawing), respectively. As shown in FIGS. 8A and 8A, the left door 810a and the right door 810b open and close with the displacement of the movers 822a and 822b of the linear motors 820a and 820b.

FIG. 8B (a) is a diagram showing a fully closed state of the FPCM type door system 850 according to the conventional technique, and FIG. 8B (b) is a diagram showing a fully open state of the FPCM type door system 850 according to the conventional technique. Is. The door system 850 is provided with a rack and pinion structure (pinion 870, as well as upper rack 880 and lower rack 890). The pinion 870 is connected to the rotating shaft of one motor (not shown). When the pinion 870 rotates in the direction of arrow A1 in FIG. 8B (a) as the motor rotates, the upper rack 880 moves toward the right side in FIG. 8B (a) (arrow A2), and the lower rack 890 , Moves toward the left side in FIG. 8B (a) (arrow A3). The upper rack 880 is connected to the right door 860b via the first connector 882, and the lower rack 890 is connected to the left door 860a via the second connector 892. Therefore, when the upper rack 880 moves toward the right side in FIG. 8B (a) (arrow A2), the right door 860b also moves in the same direction (arrow A4). Further, when the lower rack 890 moves toward the left side in FIG. 8B (a) (arrow A3), the left door 860a also moves in the same direction (arrow A5). As a result, the doors 860a and 860b are in the open state (FIG. 8B (b) as the fully open state). On the other hand, when the doors 860a and 860b are closed, the pinion 870 is rotated in the reverse direction by a motor to rotate the upper rack 880 and the right door 860b and the lower rack 890 and the left door 860a with the arrows in FIG. 8B (a). Move in the opposite direction.

Further, in a conventional vehicle door for passenger transportation, a finger jam prevention technique has been proposed that can surely prevent finger jamming in which a passenger's finger or hand is drawn into the door pocket of the vehicle (Patent Document 1). That is, in Patent Document 1, a vertical roller extending in the vertical direction along the edge of the door pocket of the vehicle door inside the vehicle is arranged, and when the door moves in the opening direction, the vertical roller serves as the moving direction of the door. Discloses a finger jam prevention device in a vehicle door, characterized in that it is rotationally driven in the opposite direction.

Further, a door technology has been proposed that allows the door to be easily pulled out even if a hand or an object is caught in the door (Patent Document 2). That is, in Patent Document 2, in a door that slides sideways to open and close, when a hand or an object is pinched, the cushioning portion is a rotating roller so that the door can be easily pulled out by pulling it to prevent an accident. The door is disclosed.

However, even in a configuration using a roller provided at the tip of the door, there is room for improvement in the structure of such a roller. For example, the rollers of Patent Document 1 and Patent Document 2 are always capable of rotating regardless of the open / closed state of the door, and are not necessarily excellent in convenience for people (passengers, etc.) around the door.

The present invention takes into consideration the above-mentioned problems, and an object of the present invention is to provide a door system that brings about a better environment for people (passengers, etc.) around the door.

Therefore, the door system according to the embodiment of the present invention includes a first slide door and a second slide door that are in contact with each other and are closed and separated from each other and are in an open state, and the first slide door and the second slide door. The first sliding door is provided with a driving means for sliding the sliding door, and the first sliding door is provided facing the door tip of the second sliding door and has a first rotation axis in the vertical direction. A roller is provided, and the second sliding door is provided facing the door end of the first sliding door and is in contact with the first door tip roller when in the closed state and has a second rotation axis in the vertical direction. The door system includes a second door roller, and the door system includes a first regulating member that selectively regulates the rotation of the first door roller by contacting and separating the first door roller. Controls the operation of the second restricting member that selectively regulates the rotation of the second door end roller by contacting and separating the second door end roller, and the operations of the first regulating member and the second regulating member. It is characterized by further having a rotation regulation control unit.

According to one embodiment of the present invention, when the first and second slide doors are closed, the first and second door tip rollers come into contact with each other. For example, if the first and second door tip rollers can be rotated by the first and second regulating members during the closing operation, it is easy to take out when something is caught between the first and second sliding doors. Will be. Further, when the 1st and 2nd sliding doors are in the fully closed state or the fully open state, for example, if the 1st and 2nd doors are made non-rotatable by the 1st and 2nd regulating members, the 1st and 2nd doors are made non-rotatable. It is possible to prevent unnecessary rotation of the rollers.

The door system includes a first electrode plate located on the door end side of the first sliding door located on the outer side in the vertical direction with respect to the first door end roller and having a first polarity, and the second door. A second roller that is located on the outer side in the vertical direction with respect to the front roller and is provided on the door end side of the second slide door so as to face the first electrode plate and has a second polarity opposite to the first polarity. It may be provided with an electrode plate.

As a result, the first and second electrode plates having different polarities are arranged to face each other on the first and second slide doors. Therefore, it is possible to strengthen the closed state of the first and second slide doors. Since the first and second electrode plates are located outside the first and second door-to-door rollers in the vertical direction, they do not positionally interfere with the first and second door-to-door rollers.

The door system includes a first damping member that cushions the impact of contact between the first door roller and the second roller on the first slide door side, the first roller, and the second door. A second damping member may be provided to soften the impact at the time of contact of the rollers on the second slide door side.

As a result, the impact generated between the first and second door tip rollers when the first and second slide doors are closed can be softened by the first and second damping members. Therefore, it is possible to protect what is sandwiched between the first and second door-end rollers.

The door system is provided with the first door roller when the first door roller and the second door roller come into contact with each other and the first door roller is displaced toward the root side of the first slide door. The second door when the first stopper in frictional contact, the first door roller, and the second door roller come into contact with each other and the second door roller is displaced toward the root side of the second slide door. A second stopper that is in frictional contact with the tip roller may be provided.

As a result, when the first and second door end rollers come into contact with each other and the first door end roller is displaced toward the root side of the first slide door, the first door end roller and the first stopper are in frictional contact with each other. It is possible to suppress unnecessary rotation of the one-door roller. Similarly, when the first and second door end rollers come into contact with each other and the second door end roller is displaced toward the root side of the second slide door, the second door end roller and the second stopper come into frictional contact with each other. It is possible to suppress unnecessary rotation of the two-door roller.

The first damping member and the second damping member may be active suspensions. In that case, the door system may include a damping force control unit that controls the damping force of the first damping member and the second damping member. Further, the damping force control unit may make the damping force when the first door roller and the second door roller are in contact smaller than the damping force when the first door roller and the second door roller are not in contact with each other.

As a result, when the first and second door end rollers come into contact with each other, the first and second damping members can be made relatively soft, and the impact of the collision of the first and second door end rollers can be softened. In addition, when the first and second stoppers are provided, the contact between the first and second door end rollers and the first and second stoppers is facilitated by facilitating the pushing of the first and second door end rollers. It becomes possible. Further, when the first and second door-end rollers are not in contact with each other, the first and second damping members are relatively hardened to facilitate the rotation of the first and second door-to-door rollers, and the first and second door-to-door rollers are easily rotated. It is possible to make it easy to take out when something is caught between the rollers, and to suppress unnecessary shaking of the first and second door-end rollers.

When the distance between the slide doors is within a predetermined range during the closing operation of the first slide door and the second slide door, the rotation regulation control unit has the first regulation member and the second regulation. The first door roller and the second roller may be allowed to rotate with the member inoperable. Further, when the distance is out of the predetermined range, the rotation regulation control unit operates the first regulation member and the second regulation member to form the first door-to-door roller and the second door-to-door roller. Rotation may be restricted. As a result, after the closing operation of the first and second sliding doors is completed (in other words, when the rotation of the first and second door-end rollers is unnecessary), the unnecessary rotation of the first and second door-end rollers is performed. It becomes possible to suppress it.

According to one embodiment of the present invention, it is possible to provide a better environment for humans (passengers and the like) around the door.

In this state, the roller 322a is rotatable. On the other hand, as shown in FIG. 3C (b), when the first regulating member 324a is in the operating state, the hand portions 350a and 350b come into contact (friction contact) by sandwiching the shaft portion 332a and are in the closed state. In this state, the rotation of the roller 322a is restricted. Since magnets 354 are provided on both sides of each of the hand portions 350a and 350b, the rotation regulation of the roller 322a in the closed state can be further tightened. Further, when the roller 322a is made of metal, for example, a method of adhering or fixing rubber (shaft covering rubber) to the portion of the shaft portion 332a sandwiched by the hand portions 350a and 350b so as not to shift. You may attach it with. By providing such a shaft covering rubber, the friction between the hand portions 350a and 350b and the central rubber 352 can be increased, and the rotation regulation of the roller 322a in the closed state can be further tightened.

FIG. 3D (a) is a plan view schematically showing when the first regulating member 324a as a second example that can be used in the door system according to the embodiment of the present invention is in the non-operating state (open state). be. FIG. 3D (b) is a plan view schematically showing a time when the first regulating member 324a as a second example that can be used in the door system according to the embodiment of the present invention is in the operating state (closed state). .. The configuration of the first regulating member 324a of the second example shown in FIGS. 3D (a) and 3D (b) is similarly applicable to the second regulating member 324b.

As shown in FIGS. 3D (a) and 3D (b), the first regulating member 324a of the second example has a first hand portion 360a and a first hand portion 360a capable of sandwiching the shaft portion 332a of the first door-end roller 322a. It has two hand portions 360b (hereinafter, also referred to as "hand portions 360a and 360b"). The hand portions 360a and 360b each have a hand portion main body 362 and a restraining claw 364, respectively. In the figure, the number of the restraining claws 364 is provided by two for each hand portion main body, but the present invention is not limited to this. It may be one or have three or more claws. A gear 370 is fixedly attached to the shaft portion 332a of the first door end roller 322a.
In one embodiment, the hand portion main body 362 has a shape having a recess toward the shaft portion 332a (gear 370). The restraining claw 364 is provided on the surface of the hand portion main body 362 on the shaft portion 332a (gear 370) side and projects toward the shaft portion 332a (gear 370).

The hand portions 360a and 360b can be sandwiched with respect to the shaft portion 332a (gear 370) by an actuator (hand portion actuator) (not shown). As shown in FIG. 3D (a), when the first regulating member 324a is in the non-operating state, the hand portions 360a and 360b are separated from the shaft portion 332a and are in the open state. In this state, the restraining claw 364 does not mesh with the gear 370, so that the roller 322a is rotatable. On the other hand, as shown in FIG. 3D (b), when the first regulating member 324a is in the operating state, the hand portions 360a and 360b come into contact with each other by sandwiching the shaft portion 332a and are closed. In this state, the restraint claw 364 meshes with the gear 370, so that the rotation of the roller 322a is restricted. According to this configuration, depending on the number of stop claws and the design of the depth of engagement between the stop claws and the gears, the push-in after the rollers 322a and 322b come into contact with each other (or the rollers 322a, 322b and the stopper 330a, The rollers 322a and 322b can be firmly fixed without frictional contact with 330b (on the other hand, the combined use with frictional contact with the stopper is not excluded).

[Control of Door vs. 300 in Example 1]
As described above, in the first embodiment, the door opening / closing control for controlling the opening / closing operation (sliding operation) of the doors 310a and 310b is executed via the door driving device 140 (FIG. 1). In one embodiment of the present invention, door open / close control is performed as follows. That is, when the driver performs an "open" operation with the door switch (not shown) of the driver's cab 120, an open signal is transmitted to each door control device 150 via the communication line 160. The control unit 152 of each door control device 150 that has received the open signal opens the doors 310a and 310b via the door drive device 140. Further, when the driver performs a "close" operation with the door switch of the driver's cab 120, a close signal is transmitted to each door control device 150 via the communication line 160. The control unit 152 of each door control device 150 that has received the close signal closes the doors 310a and 310b via the door drive device 140. The opening / closing operation of the door switch may be an automatic operation by a sensor (not shown).

When closing the doors 310a and 310b, the control unit 152 determines the contact between the electrode plates 326a and 326b (state in FIG. 3B (b)) based on the output of the door sensor 151. When the contact between the electrode plates 326a and 326b is detected, the control unit 152 controls the doors 310a and 310b to be closer to each other (or to be pushed further), and the rollers 322a and 322b are controlled to the stoppers 330a and 330b. (The state of FIG. 3B (c)).

Further, in the first embodiment, the roller rotation regulation control for restricting the rotation of the rollers 322a and 322b is executed through the operation of the first regulation member 324a and the second regulation member 324b (FIG. 3B (a) and the like). As an example, the roller rotation regulation control is performed as follows.
That is, in one embodiment of the present invention, when the control unit 152 "closes" the doors 310a and 310b, the first regulating member 324a and the second regulating member 324a and the second regulation until the rollers 322a and 322b come into contact with the stoppers 330a and 330b, respectively. The member 324b is deactivated to allow the rotation of the first door end roller 322a and the second door end roller 322b (FIGS. 3B (a) and 3B (b)). Then, when the rollers 322a and 322b come into contact with the stoppers 330a and 330b, the control unit 152 operates the first regulating member 324a and the second regulating member 324b to rotate the first door tip roller 322a and the second door tip roller 322b. To regulate.

Alternatively, in one embodiment of the present invention, when the control unit 152 "closes" the doors 310a and 310b, the first regulation is made according to the distance D (opening width of the left and right doors) between the left door 310a and the right door 310b. The operation / non-operation control of the member 324a and the second regulation member 324b can be performed. That is, when the distance D between the left door 310a and the right door 310b is within a predetermined range, the first regulating member 324a and the second regulating member 324b are deactivated and the first door tip roller 322a and the second door tip roller 322b are deactivated. Allows rotation (FIGS. 3B (a) and 3B (b)). At this time, as the "predetermined range" of the distance D, about 0 cm to 30 cm can be adopted in one embodiment. Of course, in other embodiments, an arbitrary range such as 0 cm to 50 cm or 0 cm to 60 cm can be set depending on the situation.

As shown in FIG. 3B (b), even if the rollers 322a and 322b are in contact with each other, when the rollers 322a and 322b are not in contact with the stoppers 330a and 330b, respectively, the first regulation member 324a and the second regulation With the member 324b inoperable, the rollers 322a and 322b can be allowed to rotate.

In this way, when the distance between the left and right doors is within a predetermined range, the first door roller 322a and the second door roller 322b are allowed to rotate, so that even if foreign matter is caught when the doors are tightened. Foreign matter pinched by the rotation of the door roller can be easily removed, and pinching troubles can be prevented in places.

Further, when the doors 310a and 310b are "closed" and the distance D between the doors 310a and 310b is out of the predetermined range, the first regulating member 324a and the second regulating member 324b are operated to operate the first door-end roller. The rotation of the 322a and the second door roller 322b can be restricted.

As shown in FIG. 3B (b), even if the rollers 322a and 322b are in contact with each other, if the rollers 322a and 322b are not in contact with the stoppers 330a and 330b, respectively, the first regulating member 324a and the first are not included. 2 It is possible to allow the rollers 322a and 322b to rotate by deactivating the regulating member 324b.
In this way, by restricting the rotation of the first door end roller 322a and the second door end roller 322b when the distance between the left and right doors is out of the predetermined range, the rollers are not prepared except when the doors are closed. It is possible to prevent accidents due to excessive rotation.

Further, although not shown, in one embodiment of the present invention, when the doors 310a and 310b are "opened", the control unit 152 is the first regulating member regardless of the distance D between the doors 310a and 310b. The 324a and the second regulating member 324b can be operated to control the rotation of the first door-end roller 322a and the second door-to-door roller 322b at all times. In this way, when the left and right doors are opened, the rotation of the first door end roller 322a and the second door end roller 322b is constantly regulated to prevent accidents due to careless rotation of the rollers.

Further, in another embodiment of the present invention, when an accident or the like due to the careless rotation of the roller described above is not assumed, the doors 310a and 310b are opened as well as the doors 310a and 310b. It is also possible to control the operation / non-operation of the first regulating member 324a and the second regulating member 324b according to the distance D between the 310a and the 310b. In carrying out the present invention, it is not necessary to match the behaviors of the first regulating member 324a and the second regulating member 324b when the left and right doors are closed and when the doors are opened.

[Effect of Door vs. 300 of Example 1]
According to the door pair 300 of the first embodiment as described above, when the left and right doors 310a and 310b (first and second sliding doors) are closed, the first door tip roller 322a and the second door tip roller 322b come into contact with each other. (FIG. 3B (b)). When something is caught between the doors 310a and 310b by making the first and second door end rollers 322a and 322b rotatable by the first and second restricting members 324a and 324b during this closing operation. Easy to take out. Further, when the doors 310a and 310b are fully closed or fully opened (FIGS. 3B (a) and 3B (c)), the first regulating member 324a and the second regulating member 324b are used to make the first door roller 322a and the second. By controlling the door end roller 322b so that it cannot rotate, it is possible to prevent unnecessary rotation of the first door end roller 322a and the second door end roller 322b.

The door system 110 of the first embodiment has a first electrode plate 326a which is located on the outside of the first door end roller 322a in the vertical direction and is provided on the door end side of the left door 310a and has a first polarity, and a first electrode plate 326a. A second door that is located on the outside of the two-door roller 322b in the vertical direction and is provided on the door end side of the right door 310b so as to face the first electrode plate 326a and has a second polarity opposite to the first polarity. It is provided with an electrode plate 326b (FIG. 3A, FIG. 3B (a), etc.). As a result, the first and second electrode plates 326a and 326b having different polarities are arranged to face each other on the doors 310a and 310b. Therefore, it is possible to reliably detect the closed state of the doors 310a and 310b.

The door system 110 of the first embodiment has a first damping member 328a that softens the impact when the first door roller 322a and the second door roller 322b come into contact with each other on the left door 310a side, and the same impact on the right door 310b side. A second damping member 328b for softening is provided (FIG. 3B (a) and the like). Thereby, the impact generated between the first door end roller 322a and the second door end roller 322b when the doors 310a and 310b are closed can be softened by the first damping member 328a and the second damping member 328b. Will be. Therefore, it is possible to protect what is sandwiched between the first door end roller 322a and the second door end roller 322b.

In the door system 110 of the first embodiment, when the first door roller 322a and the second door roller 322b come into contact with each other and the first door roller 322a is displaced toward the root side of the left door 310a, the first door roller The second door when the first stopper 330a in frictional contact with the 322a, the first door roller 322a, and the second door roller 322b come into contact with each other and the second door roller 322b is displaced toward the root side of the right door 310b. A second stopper 330b that is in frictional contact with the front roller 322b is provided (FIG. 3B (a) and the like). As a result, when the first door roller 322a and the second door roller 322b come into contact with each other and the first door roller 322a is displaced toward the root side of the left door 310a, the first door roller 322a and the first stopper 330a Is in frictional contact with each other, so that the rotation of the first door end roller 322a can be suppressed. Similarly, when the first door roller 322a and the second door roller 322b come into contact with each other and the second door roller 322b is displaced toward the root side of the right door 310b, the second door roller 322b and the second stopper 330b Is in frictional contact with each other, so that the rotation of the second door end roller 322b can be suppressed.

In the door system 110 of the first embodiment, the rotation regulation control unit of the control unit 152 deactivates the first regulation member 324a and the second regulation member 324b while the doors 132a and 132b are closed, and the first door roller 322a. And the rotation of the second door end roller 322b is allowed (FIGS. 3B (a) and 3B (b)). Further, when the closing operation of the doors 132a and 132b is completed, the rotation regulation control unit of the control unit 152 operates the first regulation member 324a and the second regulation member 324b to operate the first door end roller 322a and the second door end roller. The rotation of 322b is regulated (FIG. 3B (c)). As a result, after the closing operation of the doors 132a and 132b is completed (in other words, when the rotation of the first and second door-end rollers 322a and 322b is unnecessary), the first and second door-end rollers 322a and 322b are unnecessary. It is possible to suppress the rotation.

[Door vs. 400 according to Example 2]
FIG. 4A shows a first state of a part of the door pair 400 according to the second embodiment of the door system according to the embodiment of the present invention (a fully open state or a state on the way from a fully open state to a fully closed state). It is a horizontal sectional view schematically showing. FIG. 4B is a horizontal sectional view schematically showing a second state (transition state) of a part of the door pair 400 according to the second embodiment in the door system according to the embodiment of the present invention. FIG. 4C is a horizontal sectional view schematically showing a third state (fully closed state) of a part of the door pair 400 according to the second embodiment in the door system according to the embodiment of the present invention. The door pair 400 according to the second embodiment can be applied to the railway train 100 shown in FIG. 1 in the same manner as the door pair 300 according to the first embodiment. Of the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

Example 2 differs from Example 1 in the following points. That is, in the doors 310a and 310b of the first embodiment, the first damping member 328a and the second damping member 328b were coil springs (FIG. 3B (a) and the like). On the other hand, in the doors 410a and 410b of the second embodiment, the first damping member 428a and the second damping member 428b are active suspensions (FIG. 4A and the like). Further, the control unit 152 of the first embodiment has a door opening / closing control unit that controls door opening / closing and a roller rotation regulation control unit that controls roller rotation regulation as functional units. On the other hand, the control unit 152 of the second embodiment has a door open / close control unit, but does not have a roller rotation regulation control unit. Further, the control unit 152 of the second embodiment has a damping force control unit that controls the damping force (stiffness) of the active suspensions 428a and 428b as a functional unit.

[Control of Door vs. 400 of Example 2]
In the second embodiment, the same door opening / closing control as in the first embodiment is executed, but since the first regulating member and the second regulating member are not provided, the roller rotation regulation control as described in the first embodiment is not executed. .. Further, in the second embodiment, the damping force control for controlling the damping force (stiffness) of the active suspensions 428a and 428b is executed. Damping force control is performed as follows. That is, as shown in FIG. 4A, the first door end roller 422a and the second door end roller 422b are separated from each other while maintaining a gap between the first stopper 430a and the second stopper 430b, respectively. Or when the distance D between the doors 410a and 410b is within a predetermined range while maintaining a gap between the first stopper 430a and the second stopper 430b (the predetermined range is as illustrated in Implementation 1). The damping force control unit of the control unit 152 controls to increase the damping force (stiffness) of the active suspensions 428a and 428b. As a result, the rollers 422a and 422b are unlikely to change their relative positions with the door bodies 420a and 420b, so that the rollers 422a and 422b are in a rotatable state.

On the other hand, when the first door roller 422a and the second door roller 422b come into contact with each other (for example, FIG. 4B), the damping force control unit of the control unit 152 receives the damping force (solid) of the active suspensions 428a and 428b. S) is controlled to be small. As a result, the relative positions of the rollers 422a and 422b with the door bodies 420a and 420b are likely to change, so that the rollers 422a and 422b easily come into contact with the grippers 430a and 430b, and the rotation of the rollers is restricted by the frictional force. It becomes a state.

The contact between the first door roller 422a and the second door roller 422b is determined by the door sensor 151 detecting the current flowing between the electrode plates 426a and 426b due to the contact between the electrode plates 426a and 426b. Can be done. Alternatively, the determination may be made based on the distance D between the rollers 422a and 422b.

[Effect of Door vs. 400 of Example 2]
According to the second embodiment as described above, the following effects can be exerted in addition to or in place of the effects of the first embodiment.

That is, in the second embodiment, the first damping member 428a and the second damping member 428b are active suspensions (FIG. 4A and the like). The control unit 152 of the second embodiment includes a damping force control unit that controls the damping force of the first damping member 428a and the second damping member 428b. Further, the damping force control unit relatively reduces the damping force when the first door roller 422a and the second door roller 422b are not in contact with each other or are within a predetermined range (FIG. 4A). It is controlled so that the damping force at the time of contact (FIGS. 4 (b) and 4 (c)) is relatively small.

As a result, when the first door roller 422a and the second door roller 422b are in contact with each other, or when the distance D between the doors 410a and 410b is out of the predetermined range, the first damping member 428a and the second damping member 428b Is relatively soft, and it is possible to soften the impact of collision with the first door-end roller 422a and the second door-to-door roller 422b. In addition, when the first stopper 430a and the second stopper 430b are provided, the rollers 422a and 422b can be easily pushed into the first door end roller 422a and the second door end roller 422b at the above timing. It is possible to facilitate the contact between the first stopper 430a and the second stopper 430b. Further, when the first door roller 422a and the second door 422b are not in contact with each other or the distance D between the doors 410a and 410b is within a predetermined range, the first damping member 428a and the second damping member 428b are relative to each other. Since the first door roller 422a and the second door roller 422b are rotatable, it is easy to take out when a foreign substance is caught between the rollers 422a and 422b, and the first door roller 422a and the first one. It is possible to suppress unnecessary shaking of the two-door roller 422b.

[Door vs. 500 according to Example 3]
FIG. 5A shows a first state of a part of the door pair 500 according to the third embodiment in the door system according to the embodiment of the present invention (a fully open state or a state on the way from a fully open state to a fully closed state). It is a horizontal sectional view schematically showing. FIG. 5B is a horizontal sectional view schematically showing a second state (transition state) of a part of the door pair 500 according to the third embodiment in the door system according to the embodiment of the present invention. FIG. 5C is a horizontal sectional view schematically showing a third state (fully closed state) of a part of the door pair 500 according to the third embodiment in the door system according to the embodiment of the present invention. The door pair 500 according to the third embodiment can be applied to the railway train 100 shown in FIG. 1 in the same manner as the door pairs 300 and 400 according to the first and second embodiments. Of the three embodiments, the same components as those of the first embodiment or the second embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. Example 3 has the same first regulating member 524a and second regulating member 524b as in the first embodiment, and also has the same active suspensions 528a and 528b as in the second embodiment. That is, Example 3 has a configuration in which Example 1 and Example 2 are combined. Therefore, in the third embodiment, the door opening / closing control and the roller rotation regulation control are executed as in the first embodiment, and the damping force control is executed as in the second embodiment. Further, according to the third embodiment, both the effect of the first embodiment and the effect of the second embodiment can be exhibited.

[Door vs. 600 according to Example 4]
FIG. 6A shows a first state of a part of the door pair 600 according to the fourth embodiment in the door system according to the embodiment of the present invention (a fully open state or a state on the way from a fully open state to a fully closed state). 6 (b) is a horizontal cross-sectional view schematically showing a second state (transition state) of a part of the door pair 600 according to the fourth embodiment in the door system according to the embodiment of the present invention. FIG. 6 (c) is a schematic view showing a third state (fully closed state) of a part of the door pair 600 according to the fourth embodiment in the door system according to the embodiment of the present invention. It is a horizontal sectional view shown in. The door pair 600 according to the fourth embodiment can be applied to the railway train 100 shown in FIG. 1 in the same manner as the door pairs 300, 400, and 500 according to the first to third embodiments. Of the four embodiments, the same components as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

Similar to the first embodiment, in the fourth embodiment, the first damping member 628a and the second damping member 628b are coil springs. Further, like the first to third embodiments, the fourth embodiment has a first stopper 630a and a second stopper 630b. On the other hand, the fourth embodiment does not have the first regulating member and the second regulating member as in the first and third embodiments. Further, the control unit 152 of the fourth embodiment has a door open / close control unit, but does not have a roller rotation regulation control unit and a damping force control unit. Therefore, in the fourth embodiment, the same door opening / closing control as in the first to third embodiments is executed. Further, according to the fourth embodiment, it is possible to regulate the rotation of the rollers 622a and 622b by the stoppers 630a and 630b with a simple configuration.

[Modification example]
The door pairs shown in Examples 1 to 4 described above are applied to the railway vehicle 102, but the present invention is not limited to these, and other vehicles and devices (monorail, ropeway, station) using the left and right sliding doors are not limited thereto. It can be applied to platform doors, elevators, etc.).

In the first embodiment, the first electrode plate 326a and the second electrode plate 326b are provided (FIG. 3A and the like). However, focusing on, for example, the first regulating member 324a and the second regulating member 324b, the first electrode plate 326a and the second 2 The electrode plate 326b may be omitted, or a simple metal plate or the like may be adopted instead of the electrode plate. Further, for example, if attention is paid to the first electrode plate 326a and the second electrode plate 326b, the first regulation member 324a and the second regulation member 324b may be omitted. Further, in the first embodiment, the first stopper 330a and the second stopper 330b are provided (FIG. 3B (a) and the like), but if attention is paid to, for example, the first regulating member 324a and the second regulating member 324b, the first stopper 330a And the second stopper 330b may be omitted. The same applies to Examples 2 to 4.

In the first embodiment, the diameters of the rollers 322a and 322b are substantially the same as the thicknesses of the door bodies 320a and 320b (FIG. 3B (a) and the like). However, the diameter of the rollers 322a and 322b may be significantly smaller than the thickness of the door bodies 320a and 320b.

FIG. 7 is a horizontal cross-sectional view schematically showing a part of the left slide door 710a among the slide doors according to the modified example (the right slide door is symmetrical with the left slide door 710a, so the illustration and description are omitted. do). As shown in FIG. 7, the left slide door 710a has a door body 720a, a first door tip roller 722a, a first electrode plate 726a, a first damping member 728a, and a first stopper 730a.

In FIG. 7, the length H is the thickness of the door body 720a, the length h2 is the diameter of the first door end roller 722a, and the lengths h1 and h3 are tangents on the outer circumference of the roller 722a, respectively. It is the distance from the tangent line parallel to the side wall of the door body 720a to the tangent line extending from the side wall of the door body 720a. Compared with the first embodiment (FIG. 3B (a) and the like), the ratio of the diameter h2 of the roller 722a to the thickness H of the door body 720a is relatively small. The present invention is not limited to these, but the ratio can be, for example, in the range of H: h2 = 1: 1/4 to 2/3.
