Description

  The present invention relates to a platform door device that is installed on a platform of a track vehicle to protect passengers.

In recent years, on the platform for boarding / exiting in a railway vehicle station, an example of installing an open / close type platform door device to protect passengers by preventing falling on the track or contact with the railway vehicle. Has increased. In this platform door device, a platform-side passenger and a track are partitioned by a wall surface formed by a movable portion (door) and a fixed portion (door pocket), and the movable portion is stopped at a predetermined position. It is in a position that coincides with the entrance / exit of the rail vehicle.
In addition, the movable part of the platform door device has an opening (frontage) dimension with an appropriate margin for the stop condition of the tracked vehicle depending on the presence or absence of a fixed position stop device (TASC: Train Automatic Stop-position Controller). Has been.

  Moreover, when there are many entrances / exits per vehicle, the number of door pockets and doors required for formation of the opening part used as an entrance / exit increases. For this reason, in the platform door device, the distance between the openings formed between the adjacent devices, that is, the width of the opening that can be secured as the entrance / exit passage is shortened by the increase in the door pocket.

  For example, as disclosed in Patent Document 1 below, a conventional platform door device employs a two-stage telescopic structure that can store a second slide door inside the first slide door using a link. is there. This two-stage telescopic structure can reduce the lateral length (lateral width) of the door pocket by dividing the width direction (opening / closing direction) of the sliding door into two parts. For this reason, the installation interval of the platform door device, in other words, the opening width that can be secured as the entrance / exit passage can be adjusted as appropriate according to the number of entrances / exits of the track vehicle. It is easy to install the same number of opening / closing entrances.

JP 2000-177580 A

As described above, it is difficult for the platform door device corresponding to the track vehicle having a large number of entrances / exits to secure an opening width (frontage) serving as an entrance / exit passage. That is, when the ratio of the total door width (the total value of the door widths of the installed door pockets) occupying the effective length of the platform is increased, the total length of the opening that can be used as the entrance / exit is shortened.
However, if the door allowance (effective protrusion width from the door pocket when fully closed) can be increased with the same door width, it is easy to secure an opening width that can be effectively used as a doorway by shortening the door width. Become.

From such a background, in a home door apparatus that opens and closes by sliding one door, a structure that can expand the door allowance associated with opening and closing the door is desired. That is, in the conventional home door apparatus, the door needs a connecting portion with the opening / closing drive mechanism, and since this connecting portion is housed in the door pocket, a part of the door width (the end on the fully closed side) is extended. Could not be used as.
The present invention has been made to solve the above-described problems, and the object of the present invention is to use it as an allowance by connecting with an opening / closing drive mechanism in a home door device that opens and closes by sliding one door. An object of the present invention is to provide a structure capable of expanding the door allowance associated with opening and closing by reducing a door width that cannot be achieved.

In order to solve the above problems, the present invention employs the following means.
The platform door device according to the present invention is a platform door device in which a door is slid by a drive mechanism to open and close an opening for getting on and off, and a slide mechanism that slidably supports the door in the opening and closing direction. It is a linear guide slide mechanism that expands and contracts in a plurality of stages.

  According to the present invention, the linear guide slide mechanism that expands and contracts in a plurality of stages in the opening and closing direction is adopted as the sliding mechanism that slidably supports the door portion. As a result, it is possible to reduce the width of the door portion that cannot be used as the door, and to increase the door width that can be effectively used as the allowance during opening and closing.

  In the above invention, the linear guide slide mechanism includes a first stage slide rail support member fixedly supported on the door pocket side, and a first stage slide rail slidably supported by the first stage slide rail support member. A first stage linear guide slide mechanism, a second stage slide rail support member fixedly supported by the first stage slide rail, and a second stage slide rail slidably supported by the second slide rail support member It is preferable that it is a 2 step | paragraph linear slide mechanism which comprises the 2nd step | paragraph linear guide slide mechanism provided with, and fixed the said 2nd step | paragraph slide rail to the said door part. Such a two-stage linear slide mechanism can ensure the durability and stability, and can expand the door width that can be effectively used as a margin when opening and closing.

  In the above invention, the first stage slide rail and the second stage slide rail are connected and interlocked, and the first stage slide rail and the second stage slide rail are disconnected and not interlocked. A locking mechanism that selectively switches between the unlocking state and the stopper mechanism that defines a movable range in which the first-stage linear guide slide mechanism slides in the opening and closing direction and releases the locking state of the locking mechanism. Further, the lock state includes a fully closed lock state position that is locked when the closing operation is performed, and a fully open lock state position that is locked when the opening operation is performed.

According to this aspect, at the start of the opening / closing operation (at the time of the first opening / closing operation), the first-stage slide rail and the second-stage slide rail that are connected by the lock mechanism slide together to open the door. Open and close parts. The stopper mechanism of this aspect defines the movable range in which the first stage slide rail of the first stage slide mechanism slides and releases the lock mechanism. Therefore, the second stage slide separated from the first stage slide rail The rail can continue the opening / closing operation of the second stage independently.
The linear guide slide mechanism having such a configuration can set the operating force of the locking mechanism to a value smaller than the force generated when the passenger is caught, so that the safety in the event that the passenger is caught during the fully closed operation Countermeasures become easier.

  A door part opening and closing method of a home door device according to the present invention includes a slide mechanism that opens and closes an opening for getting on and off by sliding one door part with a driving mechanism, and the sliding mechanism expands and contracts in a plurality of stages in the opening and closing direction. The linear guide slide mechanism according to the above aspect is characterized in that a plurality of stages including at least the final stage are integrally connected and slid at the start of the opening / closing operation.

  According to the present invention, the linear guide slide mechanism includes the lock mechanism and the stopper mechanism of the above aspect, and at the start of the opening / closing operation, the plurality of stages including at least the final stage are integrally connected and slid. In the unlikely event that a passenger is caught during the fully-closed operation, safety measures become easier.

  According to the present invention described above, the linear guide slide mechanism that expands and contracts in a plurality of stages in the opening and closing direction is adopted as a sliding mechanism that slidably supports the door portion of the home door device that opens and closes by sliding one door. The door width that cannot be used as the allowance due to the connection with the opening / closing drive mechanism (the width of the door accommodated in the door pocket when fully closed) can be reduced, and the allowance of the door that can be used effectively when opening and closing can be increased. As a result, the door width can be shortened and the ratio of the total door width to the effective platform length can be reduced. Therefore, it is easy to secure an opening width that can be used as a doorway, Application to a platform in which track vehicles having different numbers of doors and door positions stop is also facilitated.

In addition, a linear guide slide mechanism that connects and slides at least a plurality of stages including the final stage at the start of the opening / closing operation, for example, a torque setting value for detecting a passenger's trapping by a sensor such as a torque limiter, and a lock lower than this It becomes easy to distinguish the torque setting value when the mechanism is operating. For this reason, since the set value of the sensor that detects the trapping of passengers can be set to a relatively low value, it is possible to easily and surely take safety measures when the passengers are trapped during the fully-closed operation. .
In addition, the enlargement of the opening width makes it easy to set a margin for the opening dimension necessary for the stop condition of the track vehicle.

It is a device to protect. 1 is a view of the platform door 1 viewed from the track side, and FIG. 3B is a view of the platform door 1 viewed from the platform side. Therefore, in FIG. The lower side is the home side.

That is, the platform door 1 is used for getting on and off the wall surface 2 standing on the platform H so as to block between the track side on which the track vehicle travels and the platform H side used for getting on and off passengers. In order to form the opening 3 and further open and close the opening 3 serving as a boarding / alighting passage when getting on and off the track vehicle, one door 30 stored in the door pocket 10 is driven by a drive mechanism such as an electric motor and a rack and pinion. It is configured to slide. In this case, the door pocket 10 is configured to house the door portion 30 that opens and closes the adjacent opening 3 while shifting the door portion 30 in the width direction.
The outer wall surface of the door pocket 10 having a substantially rectangular parallelepiped shape forms part of the wall surface 2 together with the door portion 30.

  Since the wall surface 2 blocks the track side and the platform H side in the opening closed state where the door 3 closes the opening 3 with the door 30, the passenger gets down on the track, It is possible to prevent the passengers from coming into contact with the track vehicle on which the vehicle travels, protect the passengers and ensure safety. In addition, the home door 1 is used as an entrance / exit passage for passengers getting on and off the track vehicle in the open state where the open portion 3 is opened by storing the door portion 30 in the door pocket 10. it can.

  Now, the above-described home door 1 is configured to slide the door 30 by the driving mechanism to open and close the opening for getting on and off, that is, to support the door 30 slidably with respect to the door pocket 10. A slide mechanism including a slide support member and a slide rail is provided. The slide mechanism of the present embodiment employs a linear guide slide mechanism (hereinafter referred to as “linear slide mechanism”) 50 that expands and contracts in two steps in the opening and closing direction. This linear slide mechanism 50 is provided with two stages (a pair of upper and lower) linear slide mechanisms 50A and B above and below the door pocket 10 and the door portion 30 in order to enable the door portion 30 to slide stably. It is good also as a structure which installs 3 steps | paragraphs or more according to 30 heights.

As shown in FIGS. 4 to 8, for example, the linear slide mechanism 50 includes a first-stage slide rail support member 51 (hereinafter referred to as “first-stage rail support portion”) fixedly supported on the door pocket 10 side and the first slide rail support member 51. A first stage linear guide slide mechanism (hereinafter referred to as “first stage linear guide”) having a first stage slide rail (hereinafter referred to as “first stage linear guide”) 52 slidably supported by the stage rail support portion 51. 53), a second-stage slide rail support member (hereinafter referred to as “second-stage rail support section”) 54 fixedly supported by the first-stage linear guide 52, and the second-stage rail support section. A second stage linear guide slide mechanism (hereinafter referred to as “second stage slide mechanism”) including a second stage slide rail (hereinafter referred to as “second stage linear guide”) 55 slidably supported by 54. 56) Configured Te, a second-stage linear guide 55 of the second-stage slide mechanism 56 is a two-stage linear slide mechanism is fixed to one side of the door portion 30.
4 and 8A, the upper side of the paper surface is the track side, the lower side of the paper surface is the home side, the right side of the paper surface of FIGS. 5 to 7 and 8C is the track side, and the left side of the paper surface is the home side.

In the upper stage linear slide mechanism 50A, the first stage linear guide slide mechanism 53 has a pair of left and right first stage rail support portions 51 fixedly supported at appropriate positions inside the door pocket 10. The first-stage rail support portion 51 is a substantially U-shaped member that engages and slidably supports three surfaces (upper surface, lower surface, and one side surface) of the first-stage linear guide 52, A pair of left and right are arranged on a straight line parallel to the sliding direction of the door portion 30. In the illustrated configuration example, the upper and lower surfaces are engaged with each other by unevenness in order to prevent the first-stage linear guide 52 from being detached from the first-stage rail support portion 51.
In the figure, reference numeral 52a denotes a slide beam that supports and slides integrally with the first-stage linear guide 52, 60 denotes a fixed beam that supports the first-stage rail support portion 51 on the door pocket 10 side, and 61 denotes two upper and lower stages. The upper and lower connecting plates integrally connect the first-stage rail support portions 51 provided in the linear slide mechanisms 50A and 50B.

In the second stage linear guide slide mechanism 56, a pair of left and right second stage rail support portions 54 are fixedly supported by a slide beam 52 a integrated with the first stage linear guide 51. The second-stage rail support portion 54 is a substantially U-shaped member that engages and slidably supports three surfaces (upper surface, lower surface, and one side surface) of the second-stage linear guide 55, A pair of left and right are arranged on a straight line parallel to the sliding direction of the door portion 30. In the configuration example shown in the figure, in order to prevent the first-stage linear guide 55 from being detached from the second-stage rail support portion 54, the upper and lower surfaces are engaged with each other by providing irregularities.
The second stage linear guide 55 is connected to the door portion 30 via a slide beam 55a that slides integrally.

  In the lower linear slide mechanism 50B, the configurations of the first stage linear guide slide mechanism 53 and the second stage linear guide slide mechanism 56 are basically the same. Therefore, in FIG. The same number is attached.

5, 7, and 8, reference numeral 70 in the drawings is a drive mechanism of the door portion 30, and a rack gear 73 that meshes with a pinion gear 72 that is rotated by an electric motor 71 is attached to the lower end portion of the door portion 30. ing. In this case, the electric motor 71 and the pinion gear 72 are disposed on the lower end portion side in the door pocket 10 and in the vicinity of the side end portion where the door portion 30 enters and exits. Such an arrangement is possible because the weight of the door portion 30 is supported by the linear guide slide mechanism 50 described above. As a result, the allowance of the door portion 30 that opens and closes together with the rack gear 73 can be ensured to the maximum. it can.
In addition, about the drive mechanism of the door part 30, it is not limited to the structure of the drive mechanism 70 mentioned above.

Hereinafter, the opening / closing operation | movement (1st Embodiment) of the door part 30 by two steps expansion and contraction is demonstrated based on FIG. 2 about the platform door 1 provided with the linear slide mechanism 50 of the structure mentioned above. In FIG. 2, the upper side of the drawing is the track side, and the home-side door pocket 10 is not shown.
FIG. 2A shows a state in which the home door 1 is fully opened (fully opened). In this state, all the door portions 30 are housed in the door pocket 10, so that the opening portion 3 for getting on and off on the left side of the paper is fully opened, and passengers can get on and off. For example, as shown in FIG. 1, there is a door pocket 10 that accommodates the opening / closing door 30 on the right side of the paper 30 in the width direction.

FIG. 2B shows a state in which the closing operation of the platform door 1 is started after the passengers get on and off. In this state, when the drive mechanism 70 operates, the door portion 30 starts to slide in the closing direction on the left side of the paper surface indicated by the arrow Sc in the drawing. At this time, in the linear slide mechanism 50, the second-stage linear guide slide mechanism 56 is first operated, and the second-stage linear guide 55 slidably supported by the second-stage rail support section 54 is connected to the door section 30. Move together in the closing direction. As a result, the door portion 30 performs the first stage closing operation.
As shown in FIG. 2 (c), the first stage closing operation is completed when the second stage linear guide 55 reaches the movable limit, as shown in FIG. Regarding the movable limit of the second-stage linear guide 55, for example, a stopper (not shown) is provided at an appropriate position (for example, near the right end) of the second-stage linear guide 55 so as to interfere with the second-stage rail support section 54. do it.

After the first stage closing operation is completed, the second stage closing operation is performed as shown in FIG. In the closing operation, in the linear slide mechanism 50, the first stage linear guide slide mechanism 53 is operated, and the first stage linear guide 52 supported slidably by the first stage rail support portion 51 is supported by the second stage rail. It moves in the closing direction integrally with the part 54 and the door part 30. Such a second-stage closing operation is performed such that, for example, the above-described stopper (not shown) and the second-stage rail support portion 54 are dragged by the drive mechanism 70 to the door portion 30 that performs the closing operation. The two-stage rail support portion 54 starts moving in the closing direction.
This closing operation is completed when the movable limit of the first stage linear guide 52 is reached, and the home door 1 is fully closed (fully closed). As for the movable limit of the first-stage linear guide 52, for example, a stopper (not shown) is provided at an appropriate position (for example, near the right end) of the first-stage linear guide 52 so as to interfere with the first-stage rail support section 51. Or you may utilize that the front-end | tip part of the door part 30 contact | abuts to the adjacent door-part front-end | tip part.

Next, an opening operation for sliding the door portion 30 in the reverse direction from the fully closed state of the home door 1 shown in FIG.
FIG. 2 (e) shows a first stage opening operation for opening the opening 3 to allow passengers to get on and off from the fully closed state where the door 30 of the home door 1 cannot get on and off by closing the opening 3. Shows the state. In this state, when the drive mechanism 70 operates in the reverse direction, the door portion 30 starts to slide in the opening direction on the right side of the drawing as indicated by an arrow So in the drawing. At this time, in the linear slide mechanism 50, the second-stage linear guide slide mechanism 56 is operated, and the second-stage linear guide 55 that is slidably supported by the second-stage rail support section 54 is opened integrally with the door section 30. Move in the direction. As a result, the door portion 30 performs the first stage opening operation.

  In the first stage opening operation, the first stage of the opening operation of the platform door is completed when the second stage linear guide 55 reaches the movable limit on the opposite side. Regarding the movable limit of the second stage linear guide 55, for example, a stopper (not shown) is provided at an appropriate position (for example, near the left end) of the second stage linear guide 55 so as to interfere with the second stage rail support section 54. do it.

After the opening operation of the first stage is completed, the opening operation of the second stage is performed as shown in FIG. In the closing operation, in the linear slide mechanism 50, the first stage linear guide slide mechanism 53 is operated, and the first stage linear guide 52 supported slidably by the first stage rail support portion 51 is supported by the second stage rail. It moves in the opening direction integrally with the part 54 and the door part 30. Such a second stage opening operation is performed so that, for example, the above-described stopper (not shown) and the second rail support portion 54 interfere with each other so as to be dragged to the door portion 30 opened by the drive mechanism 70. The two-stage rail support portion 54 starts to move in the opening direction.
This opening operation is also completed when the first stage linear guide 52 reaches the movable limit on the opposite side, and the home door 1 is fully opened (completely shown in FIGS. 2 (g) and 2 (a)). Open). As for the movable limit of the first stage linear guide 52, for example, a stopper (not shown) is provided at an appropriate position (for example, near the left end) of the first stage linear guide 52 so as to interfere with the first stage rail support section 51. do it.

  Thus, since the linear slide mechanism 50 of this embodiment is comprised so that it may expand-contract in two steps in the opening / closing direction of the door part 30, since it becomes a connection part with an opening / closing drive mechanism, it cannot be used as an allowance. The width of the door part 30 can be reduced, and the door width that can be effectively used as the allowance when opening and closing can be increased. In addition, depending on the width of the door portion 30 and the like, a member that expands and contracts in two or more stages may be employed.

Specifically, the expansion of the door width will be described. The door portion 30 of the present embodiment is a pair of left and right first stage rails that substantially support the first stage linear guide 52 in FIG. 2D in the fully closed state. The width of the connecting portion with the opening / closing drive mechanism is generally defined by the support portion 51. That is, what is housed in the door pocket 10 in the fully closed state is a width in which a pair of left and right first rail support portions 51 are installed.
However, the width of the connecting portion with the opening / closing drive mechanism necessary for opening / closing one door portion 30 with a one-step linear slide mechanism is generally in the fully closed direction (left side of the drawing) in FIG. ) From the second step rail support portion 54 to the first step rail support portion 51 in the fully open direction (right side of the drawing), it can be seen that the size is significantly increased.

Therefore, in the home door 1 that opens and closes by sliding the single door portion 30, the use of a linear slide mechanism that expands and contracts in a plurality of stages in the opening and closing direction is effective in reducing the door width, and as a result, it is used as a doorway. It becomes easy to secure the width of the opening that can be made, and it is easy to install on the platform H where track vehicles with different numbers of doors and door positions stop. That is, when the ratio of the total door width in the effective length of the platform H is large, the total length of the opening 3 that can be used as the entrance / exit is shortened, but the linear slide mechanism 50 that expands and contracts in multiple stages as in this embodiment. If it is adopted, the ratio of the total door width can be reduced.
Further, the opening width can be easily increased by setting an opening size necessary for the stop condition of the tracked vehicle regardless of the presence or absence of the fixed position stop device.

  By the way, as shown in FIG. 9A, the platform door 1 according to the above-described embodiment has a configuration in which a pair of left and right columnar door pockets 10A and 10B are connected by front and rear plate-like members 11. In such a columnar type configuration, the columnar door pockets 10 </ b> A and 10 </ b> B each include the linear slide mechanism 50, and the door portion 30 is accommodated from both sides in a space formed by the columnar door pockets 10 </ b> A and 10 </ b> B and the plate-like member 11. However, the above-described embodiment can also be applied to a box type in which the door pocket 10C is formed by one box-shaped member as shown in FIG. 9B.

<Second Embodiment>
Next, the opening / closing operation | movement (2nd Embodiment) of the door part 30 by two steps expansion / contraction is demonstrated based on FIGS. 10-13 about the platform door 1 provided with the linear slide mechanism 50 mentioned above. In addition, the same code | symbol is attached | subjected to the part similar to embodiment mentioned above, and the detailed description is abbreviate | omitted.
In this embodiment, the linear slide mechanism 50 described with reference to FIGS. 4 to 8 is used, and the door portion 30 and the opening portion 30 at the start of the opening / closing operation (first stage) by installing a lock mechanism 80 and a stopper mechanism S described later. The difference is that the first linear guide 52 is moved together. That is, the opening / closing operation of the present embodiment is different from the first embodiment in which the door portion 30 side is opened / closed independently during the first stage opening / closing operation that starts the opening / closing operation, and the door portion during the first stage opening / closing operation. 30 and the first stage linear guide 52 are moved in an integrally connected state.

  The lock mechanism 80 shown in FIG. 11 is connected (engaged) between the first stage linear guide 52 and the slide beam 52a and the door part 30 and the second stage linear guide 55, thereby opening and closing them together ( It is a device in a “locked state” to be slid. Further, the lock mechanism 80 can be switched to a “lock release state” in which the lock mechanism 80 is separated from each other and can be operated independently (independent) by releasing the connection between the two.

Two positions corresponding to the “fully closed position” and the “fully opened position” of the door 30 are provided as the positions where the lock mechanism 80 is in the “locked state”. That is, for example, one locking member (one place) is provided on the slide beam 52a, and the two locking members provided on the side of the door 30 and the “fully closed position” or “fully opened position” are provided. On the other hand, by engaging, the “locked state” in which the slide beam 52a of the first stage linear guide 52 and the second stage linear guide 55 of the door 30 are connected to each other in any one of the two locations described above. Become.
In the following description, the locked state at the fully closed position is referred to as “fully closed locked state”, and the locked state at the fully opened position is referred to as “fully opened locked state”.

Here, a configuration example of the lock mechanism 80 shown in FIG. 11 will be specifically described. The lock mechanism 80 serves as an engagement stopper 81 serving as a lock member on the slide beam 52a side and a lock member on the door portion 30 side. A leaf spring 82 is provided.
One engagement stopper 81 is a member attached to the upper end surface of the slide beam 52a, and includes a convex portion 81a formed by bending the vicinity of the center of the plate material into a mountain shape in plan view. In the illustrated configuration example, three engagement stoppers 81 are arranged at an equal pitch in the opening and closing direction, and all the convex portions 81a of each stoper 81 are directed to the door portion 30 side. Note that the three engagement stoppers 81 are similarly provided to the upper and lower slide beams 52a.

The plate spring 82 is formed by fixing one end of the plate spring that is bent in a substantially U-shape to form a convex portion 82a. A plurality of leaf springs 82 are provided over substantially the entire area in the opening / closing direction of the door portion 30, and the convex portion 82 a of the leaf spring 82 and the convex portion 81 a of the engagement stopper 81 are at the upper and lower positions of the door portion 30. They are arranged so as to face each other.
In a state where the position of the leaf spring 82 in the opening / closing direction coincides with the engagement stopper 81, the protrusion 82 a of the leaf spring 82 and the protrusion 81 a of the engagement stopper 81 are engaged with each other. That is, as indicated by an arrow 83 in FIG. 12, the leaf spring 82 can be rocked by elastically deforming one end in the vertical direction on the paper surface, so that the convex portions 81a and 82a are engaged with each other by the spring force. "And the" unlocked state "in which the mutual engagement is released upon receiving a force greater than the spring force.

  In this case, the lock state shown in FIG. 11 is the “fully closed lock state”, and the engagement stopper 81 and a plate disposed near the end portion on the opening 3 side of the door portion 30 (left side in FIG. 11). The spring 82 is engaged. The “fully open lock state” described above is a state in which the engagement stopper 81 is engaged with the leaf spring 82 disposed in the vicinity of the end portion of the door portion 30 on the door pocket 10 side (the right side in FIG. 11). At the time of transition to such a locked state, a sensor (not shown) provided as a safety device for stopping the electric motor 71 of the drive mechanism 70 causes torque fluctuations in the same manner as when the door 30 sandwiches passengers. Although detected, the torque fluctuation is much smaller than when the passenger is caught, so that it is easy to distinguish the interference between the stopper and the passenger.

Incidentally, in the illustrated engagement stopper 81, three engagement stoppers 81 are arranged at an equal pitch in the opening and closing direction. This is a countermeasure for a problem that occurs when the door portion 30 is once backed in the opening direction due to a reaction that the front end portion comes into contact with the door portion 30 when the door portion 30 is closed.
That is, the convex portions 81a and 82a that are in the “locked state” by fully closing the door portion 30 are separated from the engaged state when the door portion 30 is back in the opening direction. For this reason, the door part 30 starts to move again in the fully closed direction. At this time, if the distance to the engagement stopper 81 with which the leaf spring 82 operating integrally with the door part 30 first contacts is long, the door part 30 and The leaf spring 82 hits the first engagement stopper 81 in an accelerated state.

The plate spring 82 of the door 30 thus accelerated may lose its spring force and elastically deform, so that it may get over the engagement stopper 81 that has been hit. Therefore, by disposing a plurality (three in the illustrated example) of engagement stoppers 81 at a constant short interval, the distance (time) that the leaf spring 82 accelerates can be shortened, so that the lock mechanism 80 functions reliably. be able to.
The problem that the accelerated leaf spring 82 gets over the engagement stopper 81 can be solved by increasing the spring force of the leaf spring 82. However, if the spring force is too strong, the operation of the lock mechanism 80 and the door portion 30 are increased. Smooth opening and closing movement becomes difficult.

Next, the stopper mechanism S defines the movable range of the first stage linear guide 52 in the first stage slide mechanism 53 and releases the lock state of the lock mechanism 80 described above, so that the opening / closing operation is started from the first stage. This is a member for switching to the second stage.
That is, the stopper mechanism S has a movement range of the first-stage linear guide 52 that moves integrally with the door 30 at the start (first stage) of the opening / closing operation that is integrally opened / closed by the lock mechanism 80. By restricting, the “locked state” of the locking mechanism 80 is released, and the single movement (opening / closing operation) of the door 30 separated from the first-stage linear guide 52 is enabled. In other words, since the movement of the first stage linear guide 52 is blocked by the stopper mechanism S and the opening / closing operation of the door 30 by the drive mechanism 70 is continued, the lock mechanism 80 has a force greater than a predetermined value. As a result, the lock mechanism 80 is switched to the “unlocked state”.

In the configuration example of the stopper mechanism S shown in FIG. 13, one stopper S <b> 1 is provided on the upper side of the door pocket 10 serving as the fixed side, and two stoppers S <b> 2 and S <b> 3 are provided on the lower side of the door pocket 10. Yes. The slide beam 52a integrated with the first stage linear guide 52 on the moving side is provided with two stoppers S4 and S5 on the upper stage side, and two stoppers S6 and S6 on the lower stage side of the slide beam 52a. S7 is provided. In this case, both sides in the opening / closing direction are used as the stopper S1.
The stoppers S <b> 1 to S <b> 3 on the door pocket 10 side can be provided, for example, on the fixed beam 60 that supports the first stage rail support portion 51, the upper and lower connection plates 61, and the like.

In such a stopper mechanism S, the first stage closing operation completion position of the door portion 30 is defined by the engagement of the stoppers S1, S5 and the stoppers S3, S7, and the stoppers S1, S4 and the stoppers S2, S6 are engaged. Defines the first stage opening operation completion position of the door 30.
Note that the number and position of the stoppers S are not limited to the illustrated configuration example, and it is sufficient that the movement of the slide beam 52a is regulated within a predetermined range and the lock mechanism 80 can be released at the predetermined position.

Hereinafter, the opening / closing operation | movement (2nd Embodiment) of the door part 30 by two steps expansion and contraction is demonstrated based on FIG. 10 about the platform door 1 provided with the linear slide mechanism 50 of the structure mentioned above. In FIG. 10, as in the first embodiment of FIG. 2 described above, the upper side of the paper is the track side, and the home-side door pocket 10 is not shown.
FIG. 10A shows a state in which the home door 1 is fully open (fully open). In this case, the lock mechanism 80 is in a “fully open position locked” state (reference numeral 80F in FIG. 10). In this state, all the door portions 30 are housed in the door pocket 10, so that the opening portion 3 for getting on and off on the left side of the paper is fully opened, and passengers can get on and off. In this case, as shown in FIG. 1, for example, as shown in FIG. 1, there is a door pocket 10 that accommodates the door 30 for opening and closing the opening on the right side of the door in the width direction.

  FIG. 10B shows a state in which the closing operation of the platform door 1 is started after the passengers get on and off. In this state, when the drive mechanism 70 operates, the door portion 30 starts to slide in the closing direction on the left side of the paper surface indicated by the arrow Sc in the drawing. At this time, since the linear slide mechanism 50 is in the state of the fully open position lock 80F, the first stage linear guide 52 and the second stage linear guide 55 are in the first stage with respect to the door pocket 10 together with the door portion 30. The closing operation of is started. This closing operation is performed by the movement of the first stage linear guide 52 slidably supported by the first stage rail support portion 51.

  As shown in FIG. 10C, the first stage closing operation is performed when the first stage linear guide 52 reaches a predetermined movable limit, that is, the stoppers S1 and S5 and the stoppers S3 and S7. Is engaged, the lock mechanism 80 is released at the first-stage closing operation completion position, and the operation is completed by entering the “unlocked state”. The lock mechanism 80 in such an “unlocked state” is free when both the “fully closed locked state” and the “fully opened locked state” are released.

  After the first stage closing operation is completed, the second stage closing operation is performed as shown in FIG. Since the locking mechanism 80 is released and the closing operation is in the “unlocked state”, the first stage linear guide 52 and the second stage linear guide 55 are in a separated state in which the connection is released. Therefore, in the linear slide mechanism 50, the second-stage linear guide slide mechanism 56 operates independently, and the second-stage linear guide 55 supported by the second-stage rail support portion 54 so as to be slidable is at the movable limit. The first stage linear guide 52 that has arrived remains, and moves together with the door 30 in the closing direction.

Such a second stage closing operation is completed when the movable limit set in the second stage linear guide 55 is reached and the home door 1 is fully closed (completely closed).
When the home door 1 is fully closed, the lock mechanism 80 described above is in a “fully closed position lock” state (reference numeral 80R in FIG. 10). In this state, by taking out all the allowance of the door part 30 from the door pocket 10, the opening part 3 for boarding / alighting becomes fully closed, and boarding / alighting of a passenger becomes impossible.

Next, an opening operation for sliding the door portion 30 in the reverse direction from the fully closed state of the home door 1 shown in FIG.
FIG. 10E shows a first stage opening operation for opening the opening 3 to allow passengers to get on and off from the fully closed state where the door 30 of the home door 1 cannot get on and off by closing the opening 3. Shows the state. In this state, when the drive mechanism 70 operates in the reverse direction, the door portion 30 starts to slide in the opening direction on the right side of the drawing as indicated by an arrow So in the drawing. At this time, the lock mechanism 80 is in the fully closed position lock 80R, and the first stage linear guide slide mechanism 53 of the linear slide mechanism 50 operates. As a result, the first-stage linear guide 52 and the second-stage linear guide 55 start the first-stage opening operation with respect to the door pocket 10 together with the door portion 30. This opening operation is performed by the movement of the first stage linear guide 52 slidably supported by the first stage rail support portion 51.

  Such a first stage opening operation is performed when the first stage linear guide 52 reaches the reverse movable limit, that is, when the stoppers S1 and S4 and the stoppers S2 and S6 are engaged. The lock mechanism 80 is released at the stage where the opening operation is completed, and the operation is completed by entering the “lock release state”. The lock mechanism 80 in this state is free as both the “fully closed lock state” and the “fully open lock state” are released.

  After the first stage opening operation is completed, the second stage opening operation is performed as shown in FIG. Since the opening mechanism is in the “unlocked state” when the lock mechanism 80 is released, the connection between the first stage linear guide 52 and the second stage linear guide 55 is released. Accordingly, in the linear slide mechanism 50, the second-stage linear guide slide mechanism 56 operates by separating from the first-stage linear guide 52 where the second-stage linear guide 55 has reached the movable limit. The second stage linear guide 55 slidably supported by 54 moves in the opening direction integrally with the door portion 30.

In such a second stage opening operation, as shown in FIG. 10G, the second stage linear guide 55 reaches a predetermined movable limit, and the home door 1 is fully opened (fully opened). Complete with that.
When the home door 1 is fully opened in this way, the lock mechanism 80 described above is in a “fully open position locked” state (reference numeral 80F in FIG. 10). That is, the fully opened state of the home door 1 shown in FIG. 10 (g) is the state returned to the state of FIG. 10 (a) described above, and all the door portions 30 are accommodated in the door pocket 10, and the opening portion 3 for getting on and off. Becomes fully open and passengers can get on and off.
In addition, about the subsequent home door opening / closing operation | movement, it repeats the operation | movement mentioned above.

  As described above, the linear guide slide mechanism 50 of the present embodiment includes the locked state in which the first stage linear guide 52 and the second stage linear guide 55 are connected and interlocked, and the first stage linear guide 52 and the second stage linear guide. The lock mechanism 80 that performs selection switching between the unlocked state in which the connection of 55 is released and is not interlocked, and the movable range in which the first stage slide mechanism 53 slides in the opening and closing direction are defined, and the lock of the lock mechanism 80 is locked. And a stopper mechanism S for releasing the state. The lock state of the lock mechanism 80 includes a fully closed lock state position that is locked when the closing operation is performed, and a fully open lock state position that is locked when the opening operation is performed.

For this reason, at the time of the first stage opening / closing operation that is the start time of the opening / closing operation, the first stage linear guide 52 and the second stage linear guide 55 that are connected by the lock mechanism 80 slide together to open and close the door 30. To do. The stopper mechanism S defines a movable range in which the first stage linear guide 52 of the first stage slide mechanism 53 slides and releases the locked state of the lock mechanism 80, so that the stopper mechanism S is separated from the first stage linear guide 52. The second-stage linear guide 55 thus made can continue the second-stage opening / closing operation independently.
The linear guide slide mechanism 50 having such a configuration facilitates a safety measure in the event that a passenger is caught during a fully-closed operation, that is, a sensor for stopping the electric motor 71.

The home door apparatus 1 according to the present embodiment includes a linear guide slide mechanism 50 that opens and closes the opening 3 for getting on and off by sliding one door portion 30 with a drive mechanism 70. Since the mechanism 50 expands and contracts in a plurality of stages in the opening / closing direction, the first-stage linear guide 52 of the first-stage slide mechanism 53 and the second-stage linear of the second-stage slide mechanism 56 of the linear guide slide mechanism 50 at the start of the opening / closing operation. The opening and closing method of the door part 30 which connects and slides the guide 55 integrally becomes possible.
When the linear guide mechanism 50 has three or more stages, a plurality of stages including at least the final stage (three stages in the case of three-stage expansion / contraction) may be integrally connected and slid.

  According to such an opening / closing method, since the linear guide slide mechanism 50 integrally connects and slides a plurality of stages including at least the final stage at the start of the opening / closing operation, in the event that a passenger is caught during the fully closing operation, In the present embodiment using the lock mechanism 80, the difference from the torque fluctuation when the lock mechanism 80 is activated becomes large, so that it is easy to set a sensor for stopping the electric motor 71.

By the way, the lock mechanism 80 mentioned above can be variously modified as described below based on FIGS. In addition, Fig.14 (a) is the front view which looked at the door part 30 and the lock mechanism 80 from the track | orbit side.
FIG. 14B is a cross-sectional view taken along the line DD of FIG. 14A and shows a lock mechanism 80 of the first modification. The lock mechanism 80 is obtained by attaching a friction member 82 such as rubber or resin to the upper end surface of the slide beam 52a via a support member 81. In this case, the locked state is set by the frictional force generated between the friction member 82 having a large frictional force and the contact surface on the door part 30 side, and the opening / closing movement (sliding) between the slide beam 52a and the door part 30 is synchronized. Further, when a force greater than the frictional force is applied due to the engagement of the stopper mechanism S, the door portion 30 is separated from the slide beam 52a and becomes unlocked.

Further, the lock mechanism 80 of the second modification shown in FIG. 14C has a structure that presses the friction member 82 by applying an urging force by an elastic member such as a spring 83.
Further, the lock mechanism 80 of the third modified example shown in FIG. 14D has a structure using a magnet 84. In this case, since the door portion 30 is made of aluminum, a structure may be adopted in which an iron plate 85 with a slippery seal or the like attached to the surface is attached in place.

  The lock mechanism 80 of the fourth modified example shown in FIG. 15 uses a roller unit 86 in which a support shaft Ru is swingably attached to a support member 81A. A friction member such as rubber is used for the roller 87 of the roller unit 86. By swinging the roller unit 86 and attaching the roller unit 86 as appropriate, the roller rotation center Rc can be pressed close to the door 30 side by x (see reference numerals 86 'and 87' in the figure). Therefore, it is possible to optimize the frictional force by appropriately adjusting the value of x.

  A lock mechanism 80 of the fifth modification shown in FIG. 16 uses a rotating claw 89 that is biased in the rotation direction by a coil spring 88 instead of the leaf spring 82 shown in FIG. The rotating claw 89 is installed so as to engage with the stopper 81, and rotates when the force of a predetermined position or more is applied to release the locked state.

The lock mechanism 80 of the sixth modified example shown in FIG. 17 is a roller unit that is attached to the concave portion 90a of the timing belt 90 fixed to the door 30 and the upper end surface of the slide beam 52a via a support member 81B. 91 is engaged with the roller body 91a. In this case, the upper and lower two timing belts 90 are provided over substantially the entire region (full width) in the opening / closing direction of the door portion 30.
Further, the roller unit 91 is attached to the upper and lower two shafts 91b whose one end is supported by the support member 81B so as to be movable in the axial direction on the other end. The roller unit 91 is urged toward the timing belt 90 by a coil spring 91c interposed on the outer periphery of the shaft 91b. The urging force by the coil spring 91c can be adjusted by tightening a nut 91d that is screwed with a screw portion provided on one end side of the shaft 91b.

  The lock mechanism 80 having such a configuration is in a locked state when the roller body 91a that receives the bias of the coil spring 91c enters and engages with the recess 90a of the timing belt 90. When a force greater than a predetermined value exceeding the urging force of the coil spring 91c is applied, the roller body 91a is pushed out of the recess 90a of the timing belt 90, so that the engagement is released and the lock is released. .

  A lock mechanism 80 according to a seventh modification shown in FIG. 18 has a wire 92 attached in the opening / closing direction of the door 30 in place of the timing belt 90 described above. And the wire clamping part 93 is attached to the upper end of the slide beam 52a instead of the roller unit 91. The wire clamping portion 93 is obtained by attaching a friction member 93c such as rubber to the opposing surfaces of a pair of plate-like members 93a and 93b. In this case, the plate-like member 93a on the door portion 30 side is fixed to the tip of the shaft 91b, but the plate-like member 93b on the slide beam 52a side is movable in the axial direction of the shaft 91b. The urging | biasing toward the member 93a side is received.

  The lock mechanism 80 having such a configuration sandwiches the wire 92 between the friction member 93c of the plate-like member 93b that receives the bias of the coil spring 91c and the friction member 93c of the fixed plate-like member 93b, and generates frictional force. The locked state is maintained by the engagement with the wire 92. However, when a force exceeding the frictional force defined by the biasing force of the coil spring 91c or the frictional force of the friction member 93c is applied, the wire 92 cannot be pinched by the frictional force. The unlocked state in which the wire 93 slides is brought about.

Further, the lock mechanism 80 may detect a torque acting on the electric motor 71 of the drive mechanism 70 and operate it according to a predetermined set value.
In addition, this invention is not limited to embodiment mentioned above, For example, it can change suitably in the range which does not deviate from the summary, such as being applicable also to the boarding bridge for ships.
