A double sliding door type platform fence capable of adjusting the opening position in a wide range can be achieved in simple constitution.

Description

  The present invention relates to a platform fence or the like installed on a station platform in order to protect passenger safety.

  As a platform fence that is installed at the end of the station platform on the track side and that opens and closes a fence (also called a door panel) according to the timing of getting on and off the vehicle, the position of the fence opening 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 to 2).

JP 2005-145372 A JP 2006-290076 A

A first problem of the present invention is to realize a home fence in which an opening position can be changed according to a vehicle having a different number of doors or different door intervals, and the drive mechanism is simplified.
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. 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 the 1st fence and 2nd fence which can move along a predetermined opening-and-closing direction, the drive mechanism part which moves these fences, and one side of the said opening-and-closing direction. A door fence fixed to a platform capable of accommodating the first fence and the second fence, wherein the drive mechanism is fixed to both ends in the opening and closing direction and a driven pulley. A first timing belt wound around the opening and closing side and the one side and the other side in the opening and closing direction, and includes first and second moving pulleys, the first timing belt and the A second fence connecting portion for connecting the second fence, and one end is fixed to one end of the one side at a predetermined position, the one end is hooked on the first moving pulley from the predetermined position, and then turned toward the one side; Hanging on the first fixed pulley provided on the one side And then folded back toward the other side, then hooked on a second fixed pulley provided on the other side, folded back toward the one side again, and then hooked on the second moving pulley toward the other side. A second timing belt that is folded back toward the other end and fixed at the other end predetermined position on the other side; a predetermined position between the second fixed pulley and the second moving pulley of the second timing belt; and It is a home fence provided with the 1st fence connection part which connects the 1st fence.

  The second invention controls the rotation of the drive pulley to drive / stop the first fence and the second fence in conjunction with each other, so that the stop position of the first fence and the second fence connecting portion It is a home fence of the 1st invention further provided with the control part which controls the stop position of.

  A third invention is the home fence according to the first or second invention, wherein the second fence connecting portion is locked and connected at a predetermined position on the track side of the first timing belt.

  According to a fourth aspect of the present invention, the one end predetermined position, the installation position of the first fixed pulley, and one installation position of the driving pulley and the driven pulley are arranged in a direction intersecting the opening / closing direction, and the other end A predetermined position, an installation position of the second fixed pulley, and an installation position of the other of the driving pulley and the driven pulley are arranged in a direction crossing the opening / closing direction, and the first timing belt is disposed between both ends of the opening / closing direction. And the home fence according to any one of the first to third aspects, wherein the second timing belt is stretched.

  A fifth invention is a platform fence system configured by arranging at least a pair of platform fences according to any one of the first to fourth inventions along the longitudinal direction of the station platform so that the tips of the first fences are associated with each other. A pair of home fences arranged at an interval that is less than twice the maximum movable distance of the first fence, and a control unit for changing and controlling the tip butting position of the first fence of the pair of home fences. It is a home rail system with it.

According to the first to fourth inventions, it is possible to realize a home fence with a wide range in which the position of the opening can be set according to the door position for getting on and off the vehicle. In addition, since the drive mechanism unit requires only one motor, the structure can be simplified and the manufacturing cost can be reduced.
Moreover, in the home fence of patent document 2, since the motor which drives each fence is provided separately, obstructions, such as an umbrella and a bag, are between the fences while trying to close the fence (while the door is closed). If it gets caught, 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 present invention, since a plurality of fences are moved in conjunction with one motor, the fence stops on the spot even if an obstacle is interposed, and the relative positional relationship of the fences is shifted. That doesn't happen.

  According to 5th invention, the home fence system which can change a door 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]
FIG. 1 is a front view showing an example of an appearance of the home fence according to the present embodiment as viewed from the home side. FIG. 1 (1) shows a state where a plurality of fences are advanced to the maximum, and FIG. 1 (2) shows a state where the fences are accommodated to the limit.
FIG. 2 is a plan view illustrating a configuration example of the home fence according to the present embodiment.
FIG. 3 is a longitudinal sectional view (cross section AA in FIG. 2).

  The home fence 2 of the present embodiment is a home fence that opens and closes in a multiple sliding door manner. The home fence 2 includes a door pocket 10 fixed to the upper surface of the end of the track of the station platform 1, a first fence 11 and a second fence 12 that are moved in and out from the door pocket 10, and the fences. A drive mechanism unit 20 that supports and moves the rail, and a control unit 90 that controls the movement of the fence.

  The 1st fence 11 and the 2nd fence 12 of this embodiment are equivalent to a door panel, have the same breadth (length of an opening-and-closing direction), and are the 1st fence with respect to the door pocket part 10 in all the advance states. 11 can be advanced to a position twice as far as the tip of the second fence 12. That is, the home fence 2 of the present embodiment is a class of home fence called a “double door type” or a “double sliding door type”.

  The drive mechanism section 20 of the present embodiment is installed on the ceiling structure section 3 provided above the station platform 1, supports and suspends the first fence 11 with the first fence connection section 21, and the second fence 12 can be supported and suspended by the second fence connecting portion 22 and the fence can be moved by horizontally moving both the connecting portions. 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, and a second slider 32 at a position near the upper surface track of the ceiling structure unit 3. In this embodiment, the slide rail 30 is fixed to the upper surface of the ceiling structure portion 3, and the first slider 31 is attached to the first fence connecting portion 21, and the second slider 32 is attached to the second fence connecting portion 22. ing. 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 FIG. 2, a U-shaped support frame 40 that opens to the track side is fixed to the upper surface of the ceiling structure portion 3 that is closer to the home side than the slide rail 30 when viewed from above. A total of two timing belts, ie, a first timing belt 41 on the home side (lower side in FIG. 2) and a second timing belt 42 on the track side (upper side in FIG. 2) are stretched on the support frame 40. . The first timing belt 41 and the second timing belt 42 are both toothed belts in which teeth are formed on both sides, and the tooth profile and the tooth pitch are the same on both sides of the belt. It is.

  Specifically, the first timing belt 41 is wound around a driving pulley 44 and a driven pulley 46 that are provided on the home side of the support frame 40 (the lower side in FIG. 2) so as to face each other in the opening / closing direction. Yes. The track side of the first timing belt 41 is locked and coupled to the second fence connecting portion 22 by the first belt locking portion 47. That is, the first timing belt 41 and the second fence 12 are connected and fixed via the second fence connecting portion 22.

  The drive pulley 44 is rotated by a brake motor 48 with a built-in brake mechanism. The motor 48 with brake is controlled in rotational speed, rotational amount, and rotational direction by drive control by the control unit 90. The control unit 90 includes a CPU 91, an IC memory 92, an input / output interface 93, and an electronic / electric circuit (not shown). Then, the type information of the vehicle arriving at the station platform 1 and the opening / closing instruction signal are acquired from an external device connected via the input / output interface 93, and the fence (door panel) of the platform fence 2 is acquired based on the type information of the vehicle. The movement is controlled, and an opening is formed at a position corresponding to the entrance / exit of the vehicle.

  In addition, although the structure which latches the start end and termination | terminus of the 1st timing belt 41 to the 2nd fence connection part 22 with the two 1st belt latching | locking parts 47 is illustrated, the 1st timing belt 41 is made into cyclic | annular form. A configuration in which a part of the belt ring is sandwiched and fixed by one first belt locking portion 47 may be employed.

The second timing belt 42 is clamped and fixed to a first belt end fixing portion 51 whose starting end is fixed at one end predetermined position (left side in the example of FIG. 2) in the opening / closing direction of the support frame 40. From there, it is extended to the other side of the door opening / closing direction (right side in the example of FIG. 2), hung on the first moving pulley 52 provided in the second fence connecting portion 22, folded back to one side by the pulley, and subsequently supported. It is hung on a first fixed pulley 53 provided on one side of the frame 40.
Next, the second timing belt 42 is folded back toward the other in the opening / closing direction by the first fixed pulley 53, straddles the second fence connecting portion 22, and is provided on the other in the opening / closing direction of the support frame 40. It is hung on the second fixed pulley 54.
Subsequently, the second timing belt 42 is folded back again toward the one side in the opening / closing direction by the second fixed pulley 54 and is hooked on the second moving pulley 55 provided in the second fence connecting portion 22. Then, after being folded back toward the other side in the opening / closing direction by the pulley, the belt end is clamped and fixed to the second belt end fixing portion 56 fixed at the other end predetermined position on the other side in the opening / closing direction of the support frame 40. Has been.
The second timing belt 42 is fixed to the first fence connecting portion 21 by a second belt locking portion 57 at a predetermined position between the second fixed pulley 54 and the second moving pulley 55. That is, the second timing belt 42 and the first fence 11 are fixed via the first fence connecting portion 21. Further, the vertical positional relationship between the first fence connecting portion 21 and the second timing belt 42 is such that the first fence connecting portion 21 is on the upper side and the second timing belt 42 is on the lower side.

  The drive pulley 44, the driven pulley 46, the first moving pulley 52, the first fixed pulley 53, the second fixed pulley 54, and the second moving pulley 55 are all provided in the first timing belt 41 and the second moving pulley 55. This is a so-called “timing pulley” adapted to the specifications of the timing belt 42 and has the same number of teeth and the same nominal width.

  The driving pulley 44, the first belt end fixing portion 51, and the first fixing pulley 53 are arranged on one end side of the support frame 40 in a direction crossing the opening / closing direction. The second belt end fixing portion 56 and the second fixing pulley 54 are arranged on the other end side of the support frame 40 in the same manner in the direction intersecting 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 12 is maximized. The same applies to a configuration in which the drive pulley 44 and the driven pulley 46 are provided at opposite positions.

  FIG. 4 is a state transition diagram for explaining the operation of the home fence 2 in the present embodiment. 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 accommodated / expanded, and Fig. 4 (3) shows the fully advanced state where the fence is fully advanced. Each is shown.

  When moving the fence in the advancing direction (right direction in the example of FIG. 4) in the home fence 2 of the present embodiment, the control unit 90 rotates the drive pulley 44 clockwise toward FIG. As a result, the drive pulley 44 rotates in the clockwise direction, and the first timing belt 41 also rotates in the clockwise direction. Accordingly, the second fence connecting portion 22 fixed to the track side of the first timing belt 41 by the first belt locking portion 47 is moved in the advance direction.

  Along with this, the first moving pulley 52 and the second moving pulley 55 also move in the opening / closing direction (the right direction in the example of FIG. 4). At this time, if the moving distance of the second fence connecting portion 22 is 1 unit (one white arrow in the figure), the belt between the second fixed pulley 54 and the second moving pulley 55 is equivalent to 2 units (white). (Two arrows) move. That is, the amount of movement of the first fence connecting portion 21 and the first fence 11 connected thereto is twice that of the second fence connecting portion 22 and the second fence 12 connected thereto. That is, the first fence 11 moves so as to protrude from the door pocket portion 10 in conjunction with the second fence 12 at a double speed. With the advance of the fence, the home fence 2 can close the opening. The stop position of the leading end (end on the advancing side) of the first fence 11 is determined by the control of the stop position of the second fence connecting part 22 by the control part 90, that is, the control of the motor 48 with brake (rotation control of the drive pulley 44). Is done.

When the first fence 11 and the second fence 12 are moved in the accommodation direction (left direction in the example of FIG. 4), the control unit 90 may perform the reverse control. In other words, the brake motor 48 may be controlled so that the drive pulley 44 is rotated counterclockwise toward FIG. Thereby, the home fence 2 can form an opening.
The lateral width of the fence (width in the opening and closing direction), the locking position of the first belt locking portion 47 in the first timing belt 41, the locking position of the second belt locking portion 57 in the second timing belt 42, and between the pulleys By appropriately setting the distance, it is possible to finally accommodate all the fences in the door pocket 10 at the same timing. The degree of rotation of the drive pulley 44 is determined in advance by giving the control unit 90 information determined so as to correspond to the number of doors, the door interval, and the door opening width of the vehicle arriving at the station platform 1. 90 may be selected and controlled in light of the type of vehicle that arrives at the station platform 1 next acquired from the outside.

  As mentioned above, although the home fence 2 of this embodiment was demonstrated, the layout of each component can be changed suitably. For example, instead of adopting a suspension layout in which the drive mechanism unit 20 is provided on the ceiling structure unit 3, as shown in FIG. 5, the drive mechanism unit 20 is accommodated in the underfloor space 4 of the station platform 1, and the first fence connecting unit 21 and It can also be set as the inverted layout which raises the 2nd fence connection part 22 from under the floor, and connects with a 1st fence and a 2nd fence, respectively.

[Second Embodiment]
Next, as a second embodiment of the present invention, a home fence system that varies the position of the opening according to the number of doors and the door interval of the vehicle will be described. In addition, the same code | symbol is provided about the component similar to 1st Embodiment, and detailed description shall be abbreviate | omitted.

  FIG. 6 is an external view seen from the home side showing a configuration example of the home fence system of the present embodiment, and shows a state where the opening is closed. The home fence system 5 of this embodiment includes a home fence 2L similar to that of the first embodiment, and a home fence 2R having a symmetrical structure with respect to this, and the maximum movable distance L of the first fence 11 (FIG. 1). It is arranged along the station platform longitudinal direction at intervals less than twice (see (2)). And the home fence system 5 has the control part 90, and is comprised so that drive control of the motor 48 with a brake of each of the home fence 2L and the home fence 2R can be carried out separately.

  The drive mechanism 20L of the home fence 2L and the drive mechanism 20R of the home fence 2R are both installed on the ceiling structure unit 3 as in the first embodiment, but are installed so as to partially overlap each other. The The slide rail 30 may be common.

  FIG. 7 is a state transition diagram for explaining an operation in the case where an opening is provided at substantially the center in the home fence system 5 of the present embodiment. It should be noted that the drive mechanism 20L of the home fence 2L and the drive mechanism 20R of the home fence 2R should be described so as to partially overlap each other, but for ease of understanding (home side The notation position of the drive mechanism 20R of the home fence 2R on the right side as viewed from the side is intentionally shifted downward in the figure.

  As shown in FIG. 7 (1), when the opening is provided at the approximate center of the left and right home fences 2L, 2R, for example, the advance amounts of the first fence 11 and the second fence 12 in both the home fences are made the same. Then, they are matched at the approximate center of the home fence system 5. Then, as shown in FIG. 7 (2), when the vehicle arrives at the station platform, the first rail 11 and the left and right home rails 2L and 2R are the same distance as the entrance / exit doors are opened. The 2nd fence 12 is moved to the direction which is accommodated in each door pocket part 10. FIG. Then, an opening part can be made in the approximate center of both home fences 2L and 2R. The width of the opening can be varied by adjusting the amount of movement for accommodating the first fence 11 and the second fence 12 in the door pocket 10. And after the door of a vehicle is closed, the opening part which was opened is closed by returning the position of each 1st fence 11 and the 2nd fence 12, and it returns to the state of FIG. 7 (1). Can do.

  If the moving amount of the fence of the home fence 2L (on the left side when viewed from the home side) is made relatively smaller than the moving amount of the fence of the home fence 2R when opening the opening, FIG. The opening can be shifted to the right (as viewed from the home side) in the figure than shown in FIG. Moreover, if it is the reverse relationship, an opening part can be shifted and provided in the left side of a figure.

  FIG. 8 is a state transition diagram for explaining an operation in the case where the opening is provided close to one side of the installable range in the home fence system 5 of the present embodiment. As in FIG. 7, the notation position of the drive mechanism 20R of the home fence 2R is shifted downward in the figure.

  As shown in FIG. 8 (1), when the opening is provided on the left side of the opening installable range W, the advancement amount of the first fence 11 and the second fence 12 of the right home fence 2R is set to the maximum movable distance. On the other hand, the first fence 11 of the left-side home fence 2L is advanced by the amount of advancement that abuts against the first fence 11 of the home fence 2R. Then, as the door of the vehicle arriving at the station platform is opened, the left-side platform fence 2L is moved so as to be fully accommodated in the door pocket 10 as shown in FIG. 8 (2). An opening (a double-headed white arrow in the figure) can be opened on the leftmost side of the installable range W of the part.

  If it is desired to make the width of the opening wider than that in FIG. 8 (2), the right-side home fence 2R may be moved in the accommodation direction by the amount that the fence is to be widened. In addition, when the center position of the opening is to be shifted slightly to the center instead of the end of the installable range W, the fence of the right home fence 2R is not accommodated in the door pocket 10 without completely accommodating the left fence 2L. It is good to move suitably to the direction accommodated in the door pocket part 10. FIG. In any case, the opening position and the opening width can be changed by changing the movement amount of the fence in each of the left home fence 2L and the right home fence 2R.

  When the opening is provided close to the other installable range W of the opening, the relationship between the left and right home fences 2L and 2R described with reference to FIG. 8 may be reversed.

  That is, the control unit 90 controls the tip butting position of the first fence 11 of the platform fence 2 and the platform fence 2R and the amount of movement of the fence according to the type of the vehicle that arrives at the station platform 1, thereby depending on the type of the vehicle. In addition, an opening can be provided at an appropriate position, and an opening can be made with an optimum opening width.
