  As a platform fence that is installed at the track side end of the station platform and that opens and closes a fence (also called a door panel) according to the timing of getting on and off the vehicle, the opening position can be changed according to vehicles with different numbers of doors and door intervals. Home fences have been devised (see, for example, Patent Documents 1 and 2).

JP 2005-145372 A JP 2006-290076 A

The 1st subject of this invention is implement | achieving the home fence which can change an opening position according to the vehicle from which the number of doors and a door space | interval differ.
Moreover, in the platform fence of patent document 2, since each fence is driven separately, when obstacles, such as an umbrella and a bag, are pinched | interposed between fences while it is trying to close the fence (while the door is closed), The relative positional relationship of the fence will shift. Then, the 2nd subject of this invention is implement | achieving the home fence which cannot produce the shift | offset | difference of the fence relative position by an obstruction.

  1st invention for solving the said subject is a home fence provided with the 1st fence which can move along a predetermined opening-and-closing direction, the 2nd fence, and a door pocket, and the drive mechanism part which moves these. The drive mechanism is movable between a first timing belt wound around a first drive pulley and a driven pulley fixed at both ends in the opening / closing direction, and one side and the other side in the opening / closing direction. A first movable pulley and a second movable pulley, and a door-bag connecting portion for connecting the first timing belt and the door pocket; the first moving pulley; a first fixed provided on the one side The pulley, the second fixed pulley provided on the other side, the second moving pulley, the third fixed pulley provided on the other side, and the fourth fixed pulley provided on the one side, in order, Next to the fourth fixed pulley, the first A second timing belt stretched around a moving pulley, and the second fence so that the first fence and the second fence move in the opposite directions as the second timing belt rotates. A first fence connecting portion for connecting the first position of the timing belt and the first fence; and a second fence connecting portion for connecting the second position of the second timing belt and the second fence. A home fence including any one of the first to fourth fixed pulleys as a second drive pulley.

  According to a second aspect of the present invention, there is provided a first drive motor that rotates the first drive pulley, a second drive motor that rotates the second drive pulley, and a drive stop control of the first drive motor to stop the door pocket. And a controller for controlling the stop position by symmetrically controlling the first fence and the second fence by controlling the second drive motor and controlling the stop position. The home fence.

  3rd invention is the home fence of 1st or 2nd invention further provided with the 1st belt latching | locking part which latches and connects the said door-bag coupling | bond part in the predetermined position on the track | orbit side of the said 1st timing belt. is there.

  According to a fourth aspect of the present invention, the first fixed pulley, the fourth fixed pulley, and one of the first drive pulley and the driven pulley are arranged in a direction intersecting the opening / closing direction, and the second fixed pulley, The third fixed pulley and the other of the first drive pulley and the driven pulley are arranged in a direction intersecting the opening / closing direction, and the first timing belt and the second timing belt are disposed between both ends of the opening / closing direction. This is a home fence according to any one of the first to third inventions.

  A fifth invention is a home fence system configured by arranging a plurality of the home fences of any one of the first to fourth inventions along the longitudinal direction of the station platform, wherein the first timing belt of the home fence is provided. It is a home fence system provided with the control part which drives and changes and controls the opening position between adjacent home fences.

  According to the 1st-4th invention, the home fence which provided the door pocket which can move to the same opening-and-closing direction as the 1st fence and the 2nd fence, and also served as a door pocket is realizable. Since the fence also serving as a door pocket is movable, a home fence with a wide range in which the position of the opening can be set in accordance with the position of the entrance door of the vehicle can be realized.

  Moreover, in the platform fence of patent document 2, since each fence is driven separately, when obstacles, such as an umbrella and a bag, are pinched between fences while trying to close the fence (while the door is closed), The relative positional relationship of the fence will shift. Furthermore, if it is going to continue the operation | movement which closes a fence only by removing an obstruction (door closing operation | movement), since a fence will start a movement from the position shifted, it will not be in the original door closing state. Therefore, it is necessary to correct the positional relationship of the fences, which leads to train delay. However, according to the second to third inventions, the first timing belt moves the door pocket by driving the first drive motor, and when it stops, the brake acts to fix the position of the door pocket. Then, since the double-opening operation of the first fence and the second fence starts, even if an obstacle is caught between one or both of the first fence and the second fence, the second drive motor is restrained and the fence The position of the door pocket is not affected just by not closing. Therefore, when the obstacle is removed, the fence can be closed again.

  According to 5th invention, the home fence system which can change an opening position according to the number of doors of a vehicle and a door space | interval is realizable using the home fence in any one of 1st-4th invention.

[First Embodiment]
Next, a home fence to which the present invention is applied will be described.
FIG. 1 is an external view of a configuration example of a home fence 2 according to the present embodiment as viewed from the home side. FIG. 1 (1) shows the fully advanced state where the fence is advanced to the maximum, and FIG. 1 (2) shows the fully accommodated state where the fence is accommodated to the limit.
FIG. 2 is a plan view showing a configuration example of the home fence 2 according to the present embodiment, and shows a fully advanced state in which the fence is advanced to the maximum.
FIG. 3 is a side view showing a configuration example of the home fence 2 of the present embodiment.

  As shown in FIG. 1, the platform fence 2 of the present embodiment is a “multi-sliding door type” platform fence in which two fences and a door pocket (also serving as a third fence) are arranged along the station platform longitudinal direction. is there. In this embodiment, it is set as the 1st fence 11, the door pocket 12, and the 2nd fence 13 in order from the right side seeing from the platform side. The first fence 11 from the right (viewed from the home side) and the second fence 13 from the left (viewed from the home side) of the door pocket 12 are advanced / accommodated.

  Specifically, as shown in FIGS. 2 and 3, the door pocket 12 forms an accommodation space that opens upward and downward and between two panels facing in the thickness direction of the fence. The first fence 11 and the second fence 13 advance / enter from the left and right of the space, respectively, and are accommodated in the accommodation space so as to overlap in the thickness direction of the fence.

  The drive mechanism 20 of the present embodiment is installed on a ceiling structure 3 provided above the station platform 1 (the station platform 1 and the ceiling structure 3 are not shown in FIG. 2). The drive mechanism unit 20 supports and suspends the first fence 11 with the first fence coupling part 21, and supports and suspends the door pocket 12 with the door pocket coupling part 22 and the second fence 13 with the second fence coupling part 23. The fence can be moved by horizontally moving each connecting portion. That is, the home fence 2 of the present embodiment is a class of home fence called a so-called “suspended type”.

  Specifically, the drive mechanism unit 20 includes a slide rail 30, a first slider 31, a second slider 32, and a third slider 33 at a position near the upper surface track of the ceiling structure unit 3. In the present embodiment, the slide rail 30 is fixed to the upper surface of the ceiling structure portion 3, and the first fence connecting portion 21 has a first slider 31, the door pocket connecting portion 22 has a second slider 32, and a second fence connecting portion. A third slider 33 is attached to each 23. That is, each slider and the slide rail constitute a linear motion mechanism, and each connecting portion is supported so as to be slidable in the opening and closing direction.

  As shown in FIGS. 2 and 3, a U-shaped support frame 40 that opens to the track side is fixed to the upper surface of the ceiling structure portion 3 on the home side of the slide rail 30 when viewed from above. Yes. On the platform side of the support frame 40, a first drive pulley 44 and a driven pulley 46 that are rotated by a first drive motor 48 that is driven and controlled by the control unit 90 face each other along the opening / closing direction (that is, the station home longitudinal direction). The first timing belt 41 is wound around. In addition, at the track side portion of the belt, the door pocket connecting portion 22 that supports and suspends the door pocket 12 is locked and fixed by the first belt locking portion 47. That is, when the first drive pulley 44 is rotated by the first drive motor 48, the first timing belt 41 is rotated, and the door pocket connecting portion 22 and the door pocket 12 are moved along the opening / closing direction. The first drive motor 48 incorporates a brake mechanism that brakes rotation.

  Further, the second timing belt 42 is wound on the track side of the support frame 40. Specifically, a second drive motor 58 that is driven and controlled by the control unit 90 and a fourth fixed pulley that is rotated by the motor are provided in one of the opening and closing directions of the support frame 40 (leftward in the example of FIG. 2). A second drive pulley 50 is also provided. Note that the second drive motor 58 has a built-in brake mechanism that brakes rotation in the same manner as the first drive motor 48. Although the fourth fixed pulley is described as the second drive pulley 50, any one of the first fixed pulley 53, the second fixed pulley 54, and the third fixed pulley 59 is used as the second drive pulley instead of the fourth fixed pulley. The second drive motor 58 may be rotated.

  The second timing belt 42 is first hung from the second drive pulley 50 toward the other opening / closing direction (rightward in the example of FIG. 2) on a first moving pulley 52 fixed to the door pocket connecting portion 22 and opens / closes there. It is folded back in one direction and hooked on a first fixed pulley 53 that is fixed to the support frame 40 on the track side from the second drive pulley 50.

  The second timing belt 42 is folded back to the other in the opening / closing direction by the first fixed pulley 53, straddling the top of the door-joint connecting portion 22, and fixed to the opposite position on the other side in the opening / closing direction of the support frame 40. 2 Hung on the fixed pulley 54. Further, it is folded back again in the opening / closing direction by the second fixed pulley 54, hung on the second moving pulley 55 fixed to the door pocket connecting portion 22, and folded back to the other in the opening / closing direction. Then, the second timing belt 42 is hooked on the third fixed pulley 59 fixed to the support frame 40 at a position closer to the home side than the second fixed pulley 54 and is folded back in one of the opening and closing directions. It is hung on the drive pulley 50 to form an annular shape.

  At the portion (first position) between the second moving pulley 55 and the third fixed pulley 59 of the second timing belt 42, the first fence connecting portion 21 that supports and suspends the first fence 11 is the second belt. Locked and fixed by the locking portion 57. In addition, a second fence connecting portion 23 that supports and suspends the second fence 13 is provided at a portion (second position) between the first moving pulley 52 and the first fixed pulley 53 of the second timing belt 42. It is locked and fixed by the belt locking portion 60.

  The first drive pulley 44, the driven pulley 46, the second drive pulley 50, the first moving pulley 52, the first fixed pulley 53, the second fixed pulley 54, the second moving pulley 55, and the third fixed pulley 59 are It is a so-called “timing pulley” adapted to the specifications of the first timing belt 41 and the second timing belt 42, and has the same number of teeth and nominal width as the other pulleys.

  The first fixed pulley 53, the second drive pulley 50 (fourth fixed pulley), and the driven pulley 46 are arranged on one end side of the support frame 40 in a direction crossing the opening / closing direction. The second fixed pulley 54, the third fixed pulley 59, and the first drive pulley 44 are arranged on the other end side of the support frame 40 in the same manner in a direction crossing the opening / closing direction. For this reason, the first timing belt 41 and the second timing belt 42 are fully stretched between both ends in the opening and closing direction, and the movable distance between the first fence 11 and the second fence 13 is maximized. The same applies to a configuration in which the first drive pulley 44 and the driven pulley 46 are provided at opposite positions.

  FIG. 4 is a state transition diagram for explaining an opening / closing operation while maintaining the position of the door pocket 12 on the home fence 2. Fig. 4 (1) shows the fully accommodated state where the fence is accommodated to the limit, Fig. 4 (2) shows the intermediate state where the fence is in the middle of accommodation, and Fig. 4 (3) shows the fully advanced state where the fence is fully advanced. Show.

  In the fully accommodated state of FIG. 4A, the first drive motor 48 and the second drive motor 58 are stopped and in a braking state by a built-in brake mechanism. To advance the first fence 11 and the second fence 13 from the door pocket while keeping the position of the door pocket 12 from this state, the control unit 90 stops the first drive motor 48 as shown in FIG. While maintaining the state (braking state), the second drive pulley 50 is rotated clockwise (toward FIG. 4).

  As the second driving pulley 50 rotates in the clockwise direction, the second timing belt 42 also rotates in the clockwise direction, and the third belt locking portion 60 is located between the first moving pulley 52 and the first fixed pulley 53. The fixed second fence connecting portion 23 is moved in a direction away from the door pocket 12 (advancing direction). Similarly, the first fence connecting portion 21 fixed by the second belt locking portion 57 at the portion between the second moving pulley 55 and the third fixed pulley 59 is also away from the door pocket 12 (advance direction). Will be moved to. That is, the first fence 11 and the second fence 13 move so as to project from the door pocket 12 in conjunction with each other. Thereby, the home fence 2 can close an opening part.

  The opposite is true when the first fence 11 and the second fence 13 are accommodated from the door pocket 12, that is, when the opening of the home fence 2 is opened. That is, it is realized by the control unit 90 rotating the second drive pulley 50 counterclockwise (toward FIG. 4). Then, by appropriately driving the second drive motor 58, the first fence 11 and the second fence 13 can finally be fully accommodated in the door pocket 12 as shown in FIG. That is, the opening part for a passenger to get on and off can be made to appear on both the right and left sides of the door pocket 12. The width of the left and right openings is varied by controlling the amount by which the second drive pulley 50 is rotated.

  FIG. 5 is a state transition diagram for explaining the opening / closing operation while maintaining the position of the second fence 13 in the home fence 2. Fig. 5 (1) shows the fully advanced state where the fence has been advanced to the maximum extent, Fig. 5 (2) shows the intermediate state where the fence is being accommodated, and Fig. 5 (3) shows the fully accommodated state where the fence has been accommodated to the limit. Show.

  From the fully advanced state of FIG. 5 (1), the first fence 11 and the second fence are moved while moving the door pocket 12 and the first fence 11 toward the second fence 13 while maintaining the position of the second fence 13. To accommodate 13 in the door pocket, as shown in FIG. 5 (2), the controller 90 causes the first drive pulley 44 to rotate counterclockwise by θ (toward the movement of the door pocket 12). The first drive motor 48 is driven and controlled so that the angle is determined by the distance), and at the same time, the second drive pulley 50 rotates the first drive motor 48 double speed, that is, 2θ, counterclockwise (toward FIG. 5). Thus, the second drive motor 58 is driven and controlled.

  Since the first timing belt 41 rotates counterclockwise together with the first drive pulley 44, the door pocket connecting portion 22 and the door pocket 12 move by θ rotation (one white arrow in the figure) toward the second fence 13. Accordingly, the first moving pulley 52 and the second moving pulley 55 move in the same manner.

  As the first moving pulley 52 and the second moving pulley 55 move, the second timing belt 42 tries to move by the length of 2θ rotation (for two white arrows in the figure). However, since the second drive pulley 50 is simultaneously driven counterclockwise, the third belt locking portion 60 of the second fence connecting portion 23 does not move. Therefore, the second timing belt 42 rotates by a length corresponding to 2θ rotation while the second fence 13 does not move from the position before the rotation start. Accordingly, the position of the second belt locking portion 57 of the first fence connecting portion 21 moves in the direction of the second fence 13 by a length corresponding to 2θ rotation. That is, the first fence 11 moves at a double speed of the door pocket 12, and an opening is created on the right side of the home fence 2. The width of the opening can be varied by controlling the amount by which the first drive pulley 44 and the second drive pulley 50 are rotated. Then, by appropriately controlling the first drive motor 48 and the second drive motor 58, as shown in FIG. 5 (3), the first fence 11 and the door pocket 12 are overlapped on the second fence 13 at the same timing. , The full accommodation of the fence can be realized.

  If the second fence 13 and the door pocket 12 are moved toward the first fence 11 from the state of FIG. 5A, the control unit 90 moves the first drive pulley 44 and the second drive pulley 50 (toward FIG. 5). What is necessary is just to drive-control the 1st drive motor 48 and the 2nd drive motor 58 so that it may rotate clockwise.

  Also, from the state of FIG. 5A, the first drive pulley 44 is rotated counterclockwise by θ (toward FIG. 5) and the second drive pulley 50 is counterclockwise (toward FIG. 5). If the second drive motor 58 is controlled to rotate around 2θ “more”, the second fence 13 is moved from the position of FIG. 5A toward the door pocket 12 by an amount exceeding 2θ. Moreover, since the distance until reaching the total accommodation for the first fence 11 is thereby shortened, the entire accommodation state can be quickly achieved accordingly. In this case, when the home fence 2 is viewed as a single unit, openings with different opening widths are formed on the left and right. In other words, it can be said that the opening position is changed by shifting the position of the door pocket.

  FIG. 6 is a state transition diagram for explaining the movement of the entire fence of the home fence 2 in the present embodiment. In FIG. 6 (1), the door pocket 12 is in a substantially central position. When it is desired to move the door pocket 12 to the left of the fence, the first drive pulley 44 is rotated counterclockwise by 2θ (θ differs depending on the distance to be moved). The first drive motor 48 is driven and controlled, and the second drive motor 58 is driven and controlled so that the second drive pulley 50 rotates half the counterclockwise direction (toward FIG. 6).

  Then, as shown in FIG. 6 (2), the door pocket 12, the first fence 11 and the second fence 13 can be moved to the left as a whole while maintaining the relative positional relationship with each other. That is, the entire fence can be shifted to the left. If you want to shift the entire fence to the right, you can do the opposite. That is, it is preferable to drive the first drive motor 48 and the second drive motor 58 so that the first drive pulley 44 is rotated by 2θ clockwise and the second drive pulley 50 is rotated θ by clockwise.

  As described above, according to the home fence 2 of the present embodiment, it is possible to form openings at either one of the left and right or the two left and right, and to freely change the width of the openings. Moreover, the whole fence can be moved to a station platform longitudinal direction. Therefore, even if the number of doors, the door interval, and the door opening width differ depending on the vehicle type, the opening can be provided at an appropriate position.

[Second Embodiment]
Next, as a second embodiment of the present invention, a home fence system using a plurality of first form fences 2 will be described. In addition, the same code | symbol is provided about the component similar to 1st Embodiment, and detailed description is abbreviate | omitted.

  FIG. 7 is an external view seen from the home side showing a configuration example of the home fence system 5 of the present embodiment. The home fence system 5 has the same configuration as that of the first embodiment (as viewed from the home side), a left home fence 2L, and a right home fence 2R having a right / left target layout. Are arranged along the longitudinal direction of the station platform 1 so that the tips of the first fences 11 are attached to each other.

  In the home fence system 5, two home fences are used, but one control unit 90 is used. The control unit 90 of the present embodiment receives the type information of the vehicle that stops on the track side of its own system from an external device, and refers to the control pattern data for each vehicle type stored in advance in the IC memory to be installed. By controlling the drive motor of the home fence, the opening position and the opening width can be varied in accordance with vehicles having different numbers of doors, door intervals, and door opening widths as a whole system. That is, the control unit 90 of the present embodiment includes the first drive motor 48 and the second drive motor 58 of the left home fence 2L, and the first drive motor 48 and the second drive motor 58 of the right home fence 2R. The operation of the home fence system 5 can be controlled by individually driving and controlling the four drive motors.

  8-9 is the external view seen from the home side which shows the example of formation of the opening part by the home fence system 5. FIG. In these figures, the control unit 90 is not shown.

  In FIG. 8 (1), both the left and right home fences 2L and 2R have the first fence 11 and the second fence 13 in the fully advanced state or the intermediate advanced state, and no opening is formed.

  FIG. 8 (2) shows an example of forming an opening in the case where there is one entrance door for a vehicle stopped at the station platform 1, and the platform fence system 5 is located at a position P <b> 1 approximately in the center of the left and right. In this case, the control unit 90 of the present embodiment controls accommodation of the left and right home fences 2L and 2R while maintaining the position of the second fence 13 (see FIG. 5). As a result, the first fence 11 and the second fence 13 of each home fence are accommodated in the door pocket 12 slightly while the door pockets 12 of the left and right home fences 2L and 2R are displaced left and right respectively. An opening is formed in the center.

  FIG. 8 (3) shows an example of forming an opening in the case where there is one entrance door for a vehicle stopped at the station platform 1, and the vehicle is located at a position P 2 on the left side with respect to the platform fence system 5. In this case, the control unit 90 of this embodiment controls the accommodation of the left home fence 2L while maintaining the position of the first fence 11 without changing the state of the right home fence 2R. As a result, an opening is formed at a position corresponding to the left position P2. If the position P2 is to the right opposite to the left and right with respect to the home fence system 8, the control relationship to the home fences 2L and 2R may be reversed from that described above.

  FIG. 9 (1) shows an example of opening formation in the case where there are two entrance doors for a vehicle that has stopped at the station platform 1 and are located at positions P 3 and P 4 near the left and right ends of the platform fence system 5. In this case, the control unit 90 of the present embodiment controls accommodation of both the left home fence 2L and the right home fence 2R while maintaining the position of the first fence 11. Thereby, an opening is formed at each of the positions corresponding to the positions P3 and P4.

  As shown in FIG. 9 (2), if the interval between the positions P3 and P4 is narrower or if it is desired to have a margin in the stopping position, the second platform fence 2L and the platform fence 2R on the right side This can be dealt with by increasing the capacity of the first fence 11 and the second fence 13 and increasing the width of the opening.

  FIG. 9 (3) shows an example of opening formation when there are three entrance doors for a vehicle parked at the station platform 1 and are positioned at positions P3 and P4 near the left and right ends of the platform fence system 5 and substantially at the center P5. Is shown. In this case, the control unit 90 of the present embodiment can form openings at three locations by controlling accommodation of the left home fence 2L and the right home fence 2R to almost the entire accommodation state. it can. If the interval between position P3 and position P5 is different from the interval between position P5 and position P4, the right home fence 2R or the left home fence 2L is moved to the left and right as a whole (see FIG. 6)), it can cope.

  As mentioned above, according to the platform fence system 5 of this embodiment, even if the number of doors of a stopped vehicle, a door space | interval, and a door width are various, the opening part of a suitable width | variety can be formed in a suitable position. . In addition, in this embodiment, although the two home fences 2 used for the home fence system 5 are set, the structure set to 3 or more is also possible.

[Modification]
The embodiment to which the present invention is applied has been described above. However, the application form of the present invention is not limited to the above, and it is possible to appropriately change, add, or omit constituent elements.

  For example, in the home fence 2 of 1st Embodiment, it demonstrated as a structure accommodated in the door pocket part 70 so that the 1st fence 11 and the door pocket 12 may overlap in the thickness direction of a panel. However, like the door pocket 12C of the home fence 2 in FIG. 10, the door pocket 12C may be configured to have a space that can accommodate the first rail 11, and may be configured to accommodate the fence in a nested manner.

  Moreover, in the above-mentioned embodiment, with reference to FIG. 2, the 1st fence connection part 21 is the site | part (1st position) between the 2nd moving pulley 55 of the 2nd timing belt 42 and the 3rd fixed pulley 59. FIG. The second fence connecting portion 23 is locked and fixed to a portion (second position) between the first moving pulley 52 and the first fixed pulley 53 of the second timing belt 42. As explained. However, if the first fence 11 and the second fence 13 can move in the opposite directions with the rotation of the second timing belt 42, the engagement of the first fence connection part 21 and the second fence connection part 23 will be described. The stop / fixed position may be another position. For example, the first position, which is the fixed position of the first fence connecting portion 21, is between the first fixed pulley 53 and the second fixed pulley 54 of the second timing belt 42 and is closer to the second fixed pulley 54 than the door pocket 12. The predetermined position may be used. The second position, which is the fixed position of the second fence connecting portion 23, is between the third fixed pulley of the second timing belt 42 and the second drive pulley 50 (fourth fixed pulley), and is second than the door pocket 12. It may be a predetermined position on the side of the two-drive pulley 50 (fourth fixed pulley).
