Description

  The present invention relates to a home fence.

  2. Description of the Related Art Conventionally, as a home fence installed on a platform of a station, there is one which moves a door back and forth to open and close an entrance.

  For example, Patent Document 1 discloses a home fence that extends and retracts a bellows-like door provided between columns to open and close an entrance. In this home fence, the bellows-like door is expanded and contracted by a pair of meshing chains which can be in the form of bars in meshing with each other and can be wound in the meshing disengaging state.

  In the home fence of Patent Document 1, one end of the pair of meshing chains is connected to the end of the bellows-like door, and the other end is stored in the storage portion of the column. In addition, the pair of meshing chains mesh with the drive sprockets provided on the columns. When the meshing chain is fed out of the storage section of the column by the driving sprocket, the meshing chain meshes and becomes bar-like, and pushes out the end of the bellows-like door. As a result, the bellows-like door is extended and the entrance of the home fence is closed. On the other hand, when the meshing chain is fed to the storage portion of the column by the driving sprocket, the meshing of the rod-shaped meshing chain is released, and the meshing chain is wound around the storage portion of the column. As a result, the bellows-like door shrinks and the entrance is opened.

JP, 2013-193589, A

  In the home fence of Patent Document 1, the bellows-type door is located on the side of the column in a state where the bellows-type door is contracted and the entrance is opened. Because the bellows-type door takes space, the bellows-type door may be an obstacle to the movement of the passenger when the entrance is open. For example, the lower end of the bellows door may hit the passenger's foot.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a more compact home fence which is less likely to be an obstacle for the movement of passengers.

A home fence according to the present invention has a side wall in which a recess is formed, and includes a post installed on the home, and a movable bar that extends and retracts horizontally from the post to restrict the passage of passengers on the home. The movable bars engaged with the drive sprocket provided on the column and the drive sprocket, meshed with each other when advancing forward to the outside of the column by the drive sprocket, and were retracted to the inside of the column by the drive sprocket In the case where the pair of meshing chains are disengaged and branched and provided at the tip of the pair of meshing chains, when the pair of meshing chains is advanced, it faces the side wall of the column and the pair of meshing chains is retracted. The tip plate fitted in the recess of the column and the tubular shape are formed inside, the meshing chain engages with each other when the meshing chain is advanced to the outside of the column, accommodates the bar-shaped part, and the tip is in the tip plate The end is fixed to the bottom of the recess of the support, and the meshing chain advances and sticks and extends in a bar, and the meshing chain retracts And a, a stretchable cover is received in the recess of the column by reducing the. As the meshing chain advances to the outside of the column, the rod-shaped portion of the meshing chain extends with the cover to block the passage of passengers, and the meshed chain retracts into the column, thereby causing the branched portion of the meshing chain to support the column. The rod-shaped portion shrinks with the cover to allow passengers to pass.

  In the present invention, when the meshing chain is advanced to the outside of the column, the rod-shaped portion of the meshing chain extends horizontally from the column with the cover, thereby blocking the passage of passengers. On the other hand, when the meshing chain is retracted to the inside of the column, the meshing chain is stored in the column, and the rod-shaped portion is contracted together with the cover to allow passengers to pass. According to the present invention, a more compact home fence can be provided since the meshing chain and the cover expand and contract to prevent or allow the passenger to pass. Also, when the rod-like portion of the meshing chain is contracted to allow passengers to pass, even if the rod-shaped portion is exposed to the outside of the support, the cross-sectional area of the rod-shaped portion of the meshing chain is small. , Less likely to be an obstacle to the movement of passengers.

Hereinafter, a home fence according to an embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, the present invention will be described by taking the home fence 1 in which two movable bars 20L and 20R operate between the left column 10L and the right column 10R as an example.
In the figures, the same or equivalent parts are denoted by the same reference numerals. In the figure, the + X direction is right, the + Y direction is backward, and the + Z direction is upward.

  The home fence 1 according to the present embodiment is, as shown in FIG. 1, a left pillar 10L and a right pillar 10R provided on a platform 70 of a station, and a left pillar 10L and a right pillar 10R respectively from the left pillar 10L and the right pillar 10R. And movable bars 20L and 20R which expand and contract in the interval between

  Each of the left post 10L and the right post 10R is formed in a prismatic shape, and is disposed at a distance substantially the same as or longer than the vehicle door 60 of the train 65. Fixing bars 50 are provided on the left side wall of the left column 10L and the right side wall of the right column 10R. The fixing bar 50 extends at its end to another pillar (not shown) and blocks the passenger's passage. On the other hand, movable bars 20L and 20R are provided on the right side wall of the left column 10L and the left side wall of the right column 10R. Between the right side wall of the left column 10L and the left side wall of the right column 10R is a passenger entrance 80, and the train 65 stops so that the vehicle door 60 is positioned at the entrance 80. The movable bars 20L and 20R open and close the entrance 80.

  Here, the right column 10R and the movable bar 20R are symmetrical with the left column 10L and the movable bar 20L. Hereinafter, the left column 10L and the movable bar 20L will be described, and the description of the right column 10R and the movable bar 20R will be omitted.

  As shown in FIG. 2, the movable bar 20L is provided with a pair of meshing chains 21 which extend and contract in the horizontal direction from the left column 10L, and a driving sprocket 22 provided in the left column 10L and meshed with one of the pair of meshing chains 21. The cover 23 covers a portion of the pair of meshing chains 21 extending and contracting from the left column 10L.

  Each of the meshing chains 21 is composed of an outer plate 21a and an inner plate 21b, as shown in FIG. Each of the outer plate 21a and the inner plate 21b constitutes a link as a set of two facing each other in the front and back direction (Y direction), similarly to a known chain. More specifically, the two outer plates 21a are coupled by pins 21d to constitute an outer link. On the other hand, the two inner plates 21b are joined by a bush 21c to constitute an inner link. In the meshing chain 21, the outer link and the inner link are alternately combined in the left-right direction (X direction), similar to a known chain.

  As shown in FIG. 3A, the outer plate 21a and the inner plate 21b extend in the left and right (X direction) of the pair of meshing chains 21 and face each other. The inner plate 21 b has a hook 21 e that engages with the outer plate 21 a and the inner plate 21 b of the other meshing chain 21. As shown in FIG. 4, the hooks 21e are formed in such a shape that the hooks 21e are engaged with each other from the right end side as the pair of meshing chains 21 are gradually brought close in parallel from the left end side to the right end side. It is done. Further, the hooks 21e are formed in a shape in which the engagement is released when the left end sides of the pair of meshing chains 21 are pulled in a direction away from being parallel to each other.

  As the outer plate 21a and the inner plate 21b are shown in FIG. 3 (A), with the hooks 21e engaged, the right or left end face of the outer plate 21a and the inner plate 21b of one meshing chain 21 mesh with the other. The outer plate 21a and the inner plate 21b of the chain 21 are formed to abut on the left or right end face of the outer plate 21a and the inner plate 21b adjacent to each other.

  When the pair of meshing chains 21 are sent to the right end side so as to be parallel to each other as they go to the right end side, the hooks 21 e begin to mesh with each other from the right end side. At the portions where the hooks 21e are engaged with each other, the left or right end surfaces of the outer plate 21a and the inner plate 21b abut each other, and the pair of meshing chains 21 are formed into bars. On the other hand, when the hooks 21e on the right end are engaged with each other, the hooks 21e are disengaged from the left end when the hooks 21e on the right end are engaged with each other and the hooked chains 21 are pulled apart from the left end. The meshing chain 21 branches into two meshing chains 21. Each of the bifurcated meshing chains 21 is flexible as in a conventional chain. An example of such a meshing chain 21 is a zip chain (made by Kushimoto Chain Co., Ltd.).

  On the other hand, in the left post 10L, as shown in FIG. 4, a through hole 11 is formed which passes from the right side wall to the case 12 provided in the left post 10L. The pair of meshing chains 21 is passed through the through holes 11 and the left end extends to the case 12 in the left column 10L. The left end side of the pair of meshing chains 21 is branched into two chains in the case 12 and bent upward or downward by a projecting guide portion 13 provided on the inner wall of the case 12. The bent interlocking chain 21 is guided by the inner wall of the case 12 and wound around the case 12.

  The right end portions of the pair of meshing chains 21 are bar-shaped and extend horizontally and horizontally. The through holes 11 are formed at substantially the same height as the chest area of an adult, and the right ends of the pair of meshing chains 21 move from the through holes 11 to the outside of the left pillar 10L to block the passage of passengers. Between the bar-shaped portion on the right end side of the pair of meshing chains 21 and the branched portion on the left end side, the upper meshing chain 21 is engaged to move the pair of meshing chains 21 in the left-right direction A sprocket 22 is provided.

  The drive sprocket 22 is rotated by a drive source such as a motor (not shown). The driving sprocket 22 is provided in the vicinity of the through hole 11 of the left column 10 L, and moves the meshing chain 21 in the left-right direction along the through hole 11 as the driving sprocket 22 rotates. When the drive sprocket 22 rotates to the left, the upper meshing chain 21 moves to the right, and the pair of meshing chains 21 are rod-shaped. When the drive sprocket 22 rotates to the right, the upper meshing chain 21 moves to the left, and the pair of meshing chains 21 is released from the bar and can be bent. As a result, the meshing chain 21 expands and contracts horizontally and horizontally from the through hole 11 of the left column 10L. Further, the meshing chain 21 is taken in and out of the case 12 at the back of the through hole 11.

  The cover 23 is formed in a tubular shape. The right end of the cover 23 is fixed to the end plate 24 of the meshing chain 21, and the left end of the cover 23 is fixed to the right side wall of the left column 10L. The cover 23 is formed in a bellows shape, and expands and contracts in the horizontal direction according to the expansion and contraction of the meshing chain 21. The cover 23 prevents the passenger from coming into contact with the meshing chain 21 to ensure the safety of the passenger.

  Next, the operation of the home fence 1 will be described. When the train 65 is not stopped on the platform 70, the home fence 1 is set in a state where the entrance 80 is closed in order to ensure the safety of the passengers. More specifically, the home fence 1 sends out most of the pair of meshing chains 21 of the movable bars 20L and 20R to the outside of the left column 10L and the right column 10R and makes them rod-shaped. And between the left column 10L and the right column 10R, the tip plates 24 of the movable bars 20L and 20R abut each other, and the entrance 80 is closed.

  When the train 65 stops on the platform 70, the home fence 1 opens the entrance 80. More specifically, when the train 65 stops and it becomes possible to open the vehicle door 60, the home fence 1 rotates the driving sprockets 22 so that the pair of meshed chained chains 21 in the rod 10L is in the left column 10L. , Move into the right pillar 10R respectively. The pair of meshing chains 21 disengage from each other in the left column 10L and the right column 10R and are branched, and then stored in the case 12 of the left column 10L and the right column 10R. As a result, the movable bars 20L and 20R retract toward the left post 10L or the right post 10R. When the tip plate 24 of the meshing chain 21 moves to the wall surface of the left column 10L and the right column 10R, the home fence 1 stops the rotation of the driving sprocket 22. Thereby, the entrance 80 is opened. When the vehicle door 60 of the train 65 is opened, the passenger can get on and off the vehicle door 60.

  When the passenger's getting on and off is completed and the train 65 is ready to leave, the home fence 1 closes the entrance 80. More specifically, the home fence 1 rotates the drive sprocket 22 to the opposite side, moves the pair of meshing chains 21 to the outside of the left column 10L and the right column 10R, and makes the pair of meshing chains 21 into a bar. . As a result, the movable bars 20L and 20R move forward to the entrance 80 side. When the tip plates 24 of the movable bars 20L and 20R abut each other, the home fence 1 stops the rotation of the driving sprockets 22. Thereby, the entrance 80 is closed. As a result, the passenger is isolated from the train 65, and the train 65 can be released from the station.

  As described above, the home fence 1 according to the present embodiment includes the pair of meshing chains 21 and an extendable cover 23 that covers the rod-shaped portions of the pair of meshing chains 21. In the present embodiment, when the pair of meshing chains 21 advances to the outside of the left column 10L and the right column 10R, the bar-shaped portions of the pair of meshing chains 21 extend with the cover 23 and block the passage of passengers. Further, the pair of meshing chains 21 retracts into the left column 10L and the right column 10R, whereby the pair of meshing chains 21 is accommodated in the left column 10L and the right column 10R, and the rod-shaped portion of the meshing chain 21 Together with the cover 23 allow passengers to pass. In this manner, the expansion and contraction of the pair of meshing chains 21 and the cover 23 prevents the passage of the passenger or enables the passage of the passenger. Therefore, according to this embodiment, a more compact home fence can be provided. Further, even if the bar-shaped portions of the pair of meshing chains 21 are exposed to the outside of the left pillar 10L and the right pillar 10R when the passengers can pass, the cross-sectional areas of the bar-shaped portions are small. It is unlikely to be an obstacle to the movement of passengers.

  Conventionally, there has been a home fence which restricts the passage of passengers by moving a horizontally extending movable bar in the vertical direction. Specifically, the movable bar is raised above the height of the passenger's chest above the passenger's head to allow the passenger to pass, and then the home fence is used to lower the movable bar to block the passenger's passage. there were. In such a home fence, in order to raise the movable bar above the passenger's head, the overall height of the home fence may be high, and as a result, the installation location of the home fence may be restricted. In addition, when the movable bar is lowered, the movable bar may come in contact with the passenger's head.

  On the other hand, in the home fence 1 according to the present embodiment, the movable bars 20L and 20R expand and contract in the horizontal direction. Therefore, the height of the home fence 1 can be made lower.

  In the present embodiment, the through holes 11 of the left column 10L and the right column 10R are provided at a height near the chest of an adult, and the movable bars 20L and 20R expand and contract in the horizontal direction from the height. Therefore, there is no possibility that movable bars 20L and 20R may come in contact with the passenger's head. Further, there is no possibility that the movable bars 20L, 20R hit the feet of the passengers. Since the movable bars 20L, 20R move within the height range of the view of the passenger, according to the present embodiment, it is possible to provide the home fence 1 with higher security, and the movable bars 20L, 20R. It is unlikely to be an obstacle to the movement of passengers even in a contracted condition.

  Conventionally, there has been a home fence that slides a movable door and stores it in a door pocket. In this home fence, a door pocket having the same width as the sliding width of the movable door is required, and as a result, the home fence has been enlarged.

  On the other hand, in the home fence 1 according to the present embodiment, the movable bars 20L and 20R expand and contract by the pair of meshing chains 21. When the pair of meshing chains 21 are returned to the left column 10L and the right column 10R by the driving sprocket 22, the meshing is disengaged and branched, and is accommodated in the case 12 of each of the left column 10L and the right column 10R. . Therefore, a more compact home fence 1 can be provided.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment etc. For example, in the above-mentioned embodiment, although the part from which meshing of a pair of meshing chains 21 slipped was taken up by case 12 of left pillar 10L and right pillar 10R, the present invention is not limited to this. In the present invention, the left column 10L and the right column 10R need only have a portion for accommodating the meshing chain 21 whose meshing has been disengaged.

  As shown in FIG. 5, a case 12 may be provided in each of the left column 10L and the right column 10R in which the portions of the pair of meshing chains 21 where the meshing is released are stored in a line. In this case, the case 12 may be formed in a rectangular parallelepiped shape, and the cross-sectional shape thereof may be slightly larger than the cross-sectional shape of the meshing chain 21. With such a configuration, it is possible to make the home fence 1 more compact by making the left pillar 10L and the right pillar 10R thinner.

  In the above embodiment, the end of the cover 23 is fixed to the wall of the left column 10L or the right column 10R, but the present invention is not limited thereto. As shown in FIG. 5, a recess 14 capable of accommodating the cover 23 in a contracted state may be formed on the wall surface of the left column 10L or the right column 10R. In other words, a door pocket that accommodates the cover 23 may be formed on the left post 10L or the right post 10R. In this case, the end of the cover 23 may be fixed to the bottom of the recess 14. The recess 14 may be formed to a depth such that the tip plates 24 of the movable bars 20L and 20R are accommodated in the recess 14 in a state where the movable bars 20L and 20R are contracted. In such a configuration, when the movable bars 20L and 20R are contracted to allow the passenger to pass through the entrance 80, there is no possibility that the movable bars 20L and 20R come in contact with the passengers, and the safety is further improved. Can.

  Although said embodiment demonstrated the platform fence 1 which opens and closes the entrance / exit 80 provided between the left column 10L and the right column 10R by two movable bars 20L and 20R, this invention is not limited to this. As shown in FIG. 6, the present invention may be configured of the home fence 1 with one support 10 and two movable bars 20 that extend and contract horizontally from the support 10. In this case, the column 10 may be provided at a distance from the fixed fence 90 installed on the platform 70 of the station, and the two movable bars 20 may extend and contract between the fixed fence 90 and the column 10.

  In addition, in the form shown in FIG. 6, the movable bar 20 may be one. In the present invention, one or more of the support 10 and the movable bar 20 may be provided.
