[0009] [First embodiment] Hereinafter, a platform fence according to a first embodiment of the present invention will be described with reference to the drawings.

[0010] Fig. 1 is a conceptual diagram illustrating the platform fence 100. Fig. 1 is a diagram of the platform fence 100 as seen from the platform PF side, and shows the state in which the exterior panel on the platform PF side of the platform fence 100 has been removed. In this specification, the platform PF side of the platform fence 100 is considered to be the back side of the platform fence 100.

[0011] The platform fence 100 separates the station platform PF from the track RL. The platform fence 100 is also called a movable platform fence. The platform fence 100 is made up of a predetermined number of platform fence elements 10 lined up in a row to cover a predetermined area of ​​the platform PF. Each platform fence element 10 has a door body 20 and a platform fence main body 30. In the example of Figure 1, in each platform fence element 10, a pair of door bodies 20 protrude from the end opening of the platform fence main body 30, and the door bodies 20 close the boarding and alighting passageway, thereby forming a fence-like device that extends along the edge of the platform PF and opens and closes at appropriate positions.

[0012] The door body 20 is a door element that is housed within the platform fence main body 30 and is provided so that it can be freely inserted and removed. The door body 20 has a main door body 21 that moves laterally forward and backward from a first end 32, which is one end of the platform fence main body 30, and a secondary door body 22 that moves laterally forward and backward from a second end 33, which is the other end of the platform fence main body 30. Normally, the operations of the main door body 21 and the secondary door body 22 are controlled so that they open and close in conjunction with each other.

[0013] The platform fence main body 30 is fixed to the floor of the platform PF and has a door pocket structure that holds the door body 20 so that it can move back and forth. The platform fence main body 30 has an electric circuit system 40 and the like inside a housing 31.

[0014] A guide mechanism 50 and a transmission mechanism 60 are provided between the door body 20 and the platform fence main body 30.

[0015] In Figure 1, the platform fence element 10 on the right side is referred to as the first platform fence element 10A, and the platform fence element 10 on the left side is referred to as the second platform fence element 10B. The first platform fence element 10A has a first platform fence main body 30A and a first door body 20A that moves from the end of the first platform fence main body 30A (first end 32 on the left side in the figure) to the side where the second platform fence element 10B is located. The second platform fence element 10B has a second platform fence main body 30B and a second door body 20B that moves from the end of the second platform fence main body 30B (second end 33 on the right side in the figure) to the side where the first platform fence element 10A is located. When considering opening and closing, the first door body 20A and the second door body 20B work together to function like sliding doors that open and close in sync. In Figure 1, solid lines indicate door bodies 20A, 20B that are abutting against each other and in a closed state, and dashed lines indicate door bodies 20A, 20B that are spaced apart and in an open state. The first platform fence main body 30A and the second platform fence main body 30B are both platform fence main bodies 30 and are arranged adjacent to each other. The first door body 20A is called the main door body 21 of the first platform fence main body 30A, and the second door body 20B is called the secondary door body 22 of the second platform fence main body 30B.

[0016] The relationship between the first platform fence element 10A and the second platform fence element 10B as described above holds true between any pair of adjacent platform fence elements 10.

[0017] The first platform fence main body 30A has a first support housing 31a, a second support housing 31b, and an intermediate housing 31c. In other words, the first support housing 31a, the second support housing 31b, and the intermediate housing 31c are members that make up the housing 31. The housing 31 becomes a single first platform fence main body 30A by assembling a top panel 31d, an exterior panel (not shown), and the like to the first support housing 31a, the second support housing 31b, and the intermediate housing 31c. Similarly, the second platform fence main body 30B has a first support housing 31a, a second support housing 31b, and the intermediate housing 31c.

[0018] The first support housing 31a supports the first door body 20A (main door body 21). The second support housing 31b supports the second door body 20B (secondary door body 22). The intermediate housing 31c is provided between the first support housing 31a and the second support housing 31b, and connects the first support housing 31a and the second support housing 31b. Below, the first door body 20A and the first support housing 31a of the first platform fence main body 30A will be described. The second door body 20B and the second support housing 31b have the same configuration as the first door body 20A and the first support housing 31a, so their description will be omitted.

[0019] Fig. 2 is a conceptual diagram illustrating the first door body 20A and the housing 31 of the first platform fence element 10A among the platform fence elements 10. Fig. 3(A) is an AA cross-sectional view of the first platform fence element 10A shown in Fig. 2, Fig. 3(B) is a BB cross-sectional view of the first platform fence element 10A, and Fig. 3(C) is a CC cross-sectional view of the first platform fence element 10A.

[0020] 2 and 3(A), the first support housing 31a has a bottom member 34, a door support member 35, a pair of side support members 36 and 37, a pair of wall members 38 and 39, and an upper member 31f. The first support housing 31a is hollow. As will be described in detail later, the first support housing 31a has a double bottom formed by the bottom member 34 and the door support member 35.

[0021] The bottom member 34 is fixed to the platform PF by fixing members 82 with a fixing plate 81 sandwiched therebetween. In practice, the bottom member 34 is fixed to an embedded base BA embedded in the platform PF. This fixes the first platform fence main body 30A to the platform PF. The bottom member 34 is a plate-shaped member and has holes necessary for installing the first platform fence main body 30A, such as an installation hole 34a and a wire-passing hole 34b. The bottom member 34 may also have holes for attaching casters for carrying in. The fixing members 82 are, for example, bolts.

[0022] The installation holes 34a are through holes for fixing the first platform fence main body 30A with the fixing members 82. The installation holes 34a are elongated holes extending in one direction of the bottom member 34, and a plurality of installation holes 34a are provided in the bottom member 34. By increasing the size of the installation holes 34a, flexibility is created in the position of the fixing members 82. This makes it possible to relax the construction accuracy requirements (for example, the position of the buried base BA) on the platform PF side where the platform fence 100 is installed. Furthermore, it is possible to reuse existing buried bases BA.

[0023] In this embodiment, the installation holes 34a are arranged in two locations with a predetermined distance between them. Each of the pair of installation holes 34a extends in the longitudinal direction of the first platform fence main body 30A, i.e., in the door opening and closing direction. In other words, the installation holes 34a expand in size laterally. This allows the first platform fence main body 30A to be stably supported by multiple fixing members 82. The fixing plate 81 is a plate-shaped member with through holes 81a formed in positions corresponding to the installation holes 34a. The fixing plates 81 are arranged at both ends of each installation hole 34a in the longitudinal direction, i.e., in two locations, and are fixed in each installation hole 34a by the fixing members 82. As a result, the fixing plate 81 is fixed while pressing down on the bottom member 34, so that the fixing strength can be maintained while the fixing plate 81 is fixed to the embedded base BA embedded in a predetermined position.

[0024] The wire-passing hole 34b is a through-hole for passing wires to the electric circuit system 40 and the like provided in the first platform fence main body 30A. The wire-passing hole 34b is disposed in approximately the center of the bottom member 34, for example.

[0025] Fig. 4 is a perspective view illustrating the embedded base BA. Fig. 5(A) is a view illustrating the state before the fixing member 82 is fixed to the embedded base BA, and Fig. 5(B) is a view illustrating the state after the fixing member 82 has been fixed to the embedded base BA. Figs. 5(A) and 5(B) are conceptual perspective views of the first platform fence main body 30A as viewed from the track RL side shown in Fig. 1. In the example of Fig. 5(A) etc., there is one fixing plate 81, and through holes 81a that are shorter than the installation holes 34a are provided in three places in the same direction, for a total of six.

[0026] As shown in Figures 4 and 5(A), the embedded base BA has fixing holes Bh for fixing the fixing member 82. The embedded base BA is embedded in the platform PF so that the fixing holes Bh are exposed. The embedded base BA shown in the figure is used for one installation hole 34a in the bottom member 34. In other words, two embedded bases BA are required for one platform fence main body 30. Although three fixing holes Bh are shown, only the two nearest ones are actually used for fixing. The fixing holes Bh are formed in the fastening parts BJ, such as nuts, that support the fixing member 82. The embedded base BA shown in the figure has a circular outer shape, but this can be modified as needed. As shown in Figure 5(A), the fixing member 82 is aligned with the fixing holes Bh in the embedded base BA and inserted into the installation holes 34a in the bottom member 34. As shown in Figure 5(B), the bottom member 34 is fixed to the embedded base BA by tightening the fixing members 82 into the fixing holes Bh.

[0027] Returning to Figures 2 and 3(A), the door body support member 35 is disposed above the bottom member 34 and supports the first door body 20A. In this embodiment, the door body support member 35 supports the first door body 20A from the bottom member 34 side. This gives the first platform fence main body 30A a double bottom, allowing the first door body 20A to be stably supported while being raised above the platform PF. Because the member supporting the first door body 20A is not disposed at the bottom of the first platform fence main body 30A, a space is created between the bottom member 34 and the first door body 20A or the door body support member 35. This space prevents interference with installation tools and the like when installing the first platform fence main body 30A and running wires, improving work efficiency.

[0028] The door body support member 35 is a plate-shaped member to which a support base member Rx that supports the first door body 20A is fixed. The support base member Rx supports the first door body 20A by supporting a base 52b of a guide mechanism 50, which will be described later. The support base member Rx is fixed to the door body support member 35 with, for example, bolts.

[0029] The pair of side support members 36, 37 extend vertically from both ends of the bottom member 34 in the longitudinal direction or the door opening / closing direction, perpendicular to the door opening / closing direction, and support the door support member 35 and the upper member 31f. The pair of wall members 38, 39 extend vertically from both ends of the bottom member 34 in the lateral direction or the horizontal direction perpendicular to the door opening / closing direction, and support the door support member 35 and the upper member 31f. The upper member 31f is disposed on the top of the first support housing 31a. The side support members 36, 37, the wall members 38, 39, and the upper member 31f are frame-shaped or plate-shaped members. The side support member 36 on the first end 32 side has an opening 36a that allows the first door 20A to move forward and backward (see FIG. 3(A)). The upper member 31f may be omitted. In this case, the top plate 31d is directly attached to the side support members 36, 37 and the wall members 38, 39.

[0030] Returning to Figure 1, in each platform fence body 30, the electrical circuit system 40 is a component used to control and drive the platform fence elements 10, enabling the electrically operated opening and closing of the door body 20. The electrical circuit system 40 includes a control device 41, a driving force generating device 44, etc.

[0031] Of the electrical circuit system 40, the control device 41, driving force generating device 44, etc. are arranged on a circuit board (not shown) and fixed to the housing 31. The electrical circuit system 40 provided in the series of platform fence elements 10 is connected via a communication line CC to a general control device 107 that is separately provided on the platform PF or its periphery. The control device 41 includes a computer, receives opening / closing signals, etc. from the general control device 107, and controls the operation of the platform fence elements 10. The driving force generating device 44 generates a driving force to move the door body 20. The driving force generating device 44 has a first motor 44a that drives the main door body 21 and a second motor 44b that drives the secondary door body 22.

[0032] The guide mechanism 50 has, for example, a guide rail 51 provided on the door body 20 side and a sliding member 52 supported on the housing 31. The sliding member 52 includes a roller, an adjustment jig, etc., and is relatively movable along the guide rail 51, allowing the door body 20 to move in the ±X directions, i.e., horizontally, relative to the housing 31. The guide rail 51 and the sliding member 52 are provided corresponding to the upper and lower parts of the door body 20, respectively, and allow the door body 20 to move smoothly horizontally, i.e., to open and close smoothly.

[0033] As shown in FIG. 2, the sliding member 52 has a guide block 52a and a base 52b. The guide block 52a has a groove (not shown), which allows the guide rail 51 (shown in FIG. 1) to slide. The upper sliding member 52 and the lower sliding member 52 are supported by the base 52b. Although not shown, the base 52b extends in a vertical direction perpendicular to the door opening / closing direction, and is connected above and below. The base 52b is fixed to a support base member Rx provided on the door support member 35. As a result, the sliding member 52 is indirectly supported by the door support member 35 of the housing 31.

[0034] The guide mechanism 50 may be one in which the guide rail 51 is fixed to the housing 31 and the sliding member 52 is fixed to the door body 20. Alternatively, the lower guide rail 51 may be provided at the bottom of the first door body 20A, and the guide block 52a of the sliding member 52 may support the guide rail 51 from below.

[0035] As shown in FIG. 1 , the transmission mechanism 60 includes an open-end timing belt 61 fixed at one end to the door body 20 and at the other end to the housing 31, and multiple pulleys 62 around which the timing belt 61 is wound. One of the multiple pulleys 62 is connected to a driving force generator 44 and transmits the driving force of the driving force generator 44 to the door body 20. Specifically, the transmission mechanism 60 and the driving force generator 44 are provided corresponding to the main door body 21 and the secondary door body 22, respectively. As a result, the driving force of the first motor 44a is transmitted to the main door body 21 via the pulley 62 and the timing belt 61, and the driving force of the second motor 44b is transmitted to the secondary door body 22 via the pulley 62 and the timing belt 61, so that both door bodies 20 can be displaced to desired positions in the lateral direction, i.e., the ±X direction, relative to the platform fence main body 30.

[0036] In the above, the driving force generating device 44 and the transmission mechanism 60 function as a driving device 91 or a driving mechanism 92 that displaces the door body 20 relative to the platform fence main body 30 via a timing belt 61. The open-end type timing belt 61 makes it easy to gather the driving mechanism 92 and other components in one place, making it easier to secure space within the platform fence main body 30.

[0037] FIG. 6 is a partially cutaway front view conceptually illustrating the structure of the door body 20 of the platform fence element 10.

[0038] A timing belt 61 is attached to the first door body 20A or the main door body 21. Teeth 61t are formed on one surface of the timing belt 61. A first end 61a of the timing belt 61, located on the left side in the drawing, is fixed to a first belt clamp 68a provided on the main door body 21, and a second end 61b of the timing belt 61, located on the right side in the drawing, is fixed to a second belt clamp 68b provided on the main door body 21. The first belt clamp 68a and the second belt clamp 68b are supported by a frame portion 21c of the main door body 21. The first belt clamp 68a is slidable in the lateral X direction relative to the main door body 21 by a guide mechanism 66a, and is positionable in the lateral X direction relative to the main door body 21 by a positioning device 66b. The guide mechanism 66a and the positioning device 66b constitute an adjustment mechanism 66 for adjusting the belt tension of the timing belt 61. Although not shown, the guide mechanism 66a is a mechanical mechanism having a long hole provided on the main door body 21 side and a movable engagement member provided on the first belt clamp 68a side that moves along the long hole.

[0039] A drive pulley 62a and an idler pulley 62b that make up the pulley 62 are attached to the support base member Rx (see Figure 2, etc.) of the first platform fence main body 30A, and a timing belt 61 is looped around the drive pulley 62a and the idler pulley 62b. The drive pulley 62a is driven by the first motor 44a to rotate at a desired speed and timing, and moves the main door body 21 in the lateral X direction via the timing belt 61, opening and closing the main door body 21 relative to the first platform fence main body 30A.

[0040] The above has described the first door body 20A or the main door body 21, but the second door body 20B or the secondary door body 22 (see Figure 1) is provided with a timing belt 61 and adjustment mechanism 66 similar to those of the first door body 20, and the secondary door body 22 can be moved horizontally in the X direction via the timing belt 61 driven by the second motor 44b, thereby opening and closing the secondary door body 22 relative to the second platform fence main body 30B.

[0041] A method for installing the platform fence 100 will be described with reference to Figure 7. The installation of the first platform fence main body 30A will be described below, but the installation of the second platform fence main body 30B is carried out in the same manner as the first platform fence main body 30A. An embedded base BA is provided in advance on the platform PF at a predetermined location where the platform fence 100 will be installed.

[0042] First, the first platform fence main body 30A is temporarily fixed to the embedded base BA (Step S11). Specifically, the bottom member 34 is fixed with the fixing members 82 so that it is sandwiched between the fixing plates 81. The fixing members 82 are inserted into the installation holes 34a of the bottom member 34 and the fixing holes Bh of the embedded base BA. The fixing members 82 are tightened so that there is some play in the fixing holes Bh.

[0043] Next, the position of the first platform fence main body 30A is adjusted and the level is adjusted (step S12). For example, the height between the bottom member 34 and the embedded base BA is adjusted using a shim or the like to adjust the inclination of the first platform fence main body 30A.

[0044] Next, the first platform fence main body 30A is finally fixed to the embedded base BA (step S13). Specifically, the fixing members 82 are finally tightened to finally fix the bottom member 34 to the embedded base BA.

[0045] Next, the electrical circuit system 40 of the first platform fence main body 30A is wired (step S14). Specifically, electric wires, cables, etc. are led into the housing 31 through the wire passage hole 34b of the bottom member 34 and wired into the electrical circuit system 40.

[0046] Finally, exterior panels and the like are attached to the housing 31 (step S15).

[0047] According to the platform fence 100, the door body 20 can be supported in a state where it is raised above the bottom member 34, creating space at the bottom of the platform fence main body 30. This makes it possible to provide the installation holes 34a for inserting the fixing members 82 and the wire-passing holes 34b for wiring in the bottom member 34 without considering the position of the door body 20. Furthermore, installation tools do not interfere with the door body when the platform fence main body 30 is fixed, improving the efficiency of the installation work.

[0048] Second Embodiment A second embodiment, which is a modification of the first embodiment, will be described below. In the second embodiment, parts common to the first embodiment will be given the same reference numerals and descriptions thereof will be omitted.

[0049] Figure 8(A) is a conceptual diagram explaining the first door body 20A and housing 31 of the first platform fence element 10A among the platform fence elements 10, and Figure 8(B) is a BB cross-sectional view of the first platform fence element 10A shown in Figure 8(A).

[0050] 8(A) and 8(B), the installation holes 34a of the bottom member 34 are not elongated holes but short holes corresponding to the shape of the fixing members 82. The installation holes 34a are arranged in four locations, at the four corners of the bottom member 34. In this embodiment, the fixing members 82 are inserted into the installation holes 34a without the fixing plate 81 shown in FIG. 2 etc. interposed therebetween.

[0051] 〔others〕 The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention.

[0052] In the above, the shapes and structures of the door body 20 and the platform fence main body 30 are merely examples, and the present invention can be applied to various types of platform fence elements 10 or platform fences 100 that use a timing belt 61 to drive the door body 20 to open and close.

[0053] In the above embodiment, the arrangement, size, shape, etc. of the installation holes 34a and the wire-passing holes 34b of the bottom member 34 can be changed as appropriate. The arrangement, size, shape, number, etc. of the fixing plates 81 can also be changed as appropriate. The arrangement, shape, size, etc. of the embedded base BA and the arrangement of the fixing holes Bh can also be changed as appropriate.

[0054] In the above embodiment, as shown in FIGS. 9(A) and 9(B), a groove 34d or a step may be provided in the bottom member 34.

[0055] In the above embodiment, the bottom of the platform fence main body 30 is double-bottomed to raise the door body 20 from the bottom member 34, but other methods may be used to raise the door body 20 from the bottom member 34. For example, the door body 20 may be suspended from the ceiling or fixed to the wall surfaces of the wall members 38, 39 of the platform fence main body 30, thereby raising the door body 20 from the bottom member 34.
