[0041] Below, refer to Figure 1 to Figure 14 Next, an embodiment of the platform door device will be described.

[0042] like Figure 1 As shown, the platform door device 5 includes a door storage portion 10, a first door 20, and a second door 30. The door storage portion 10 is fixed to the platform 3. The first door 20 and the second door 30 are double-layer sliding doors, which are arranged in a manner that allows them to move forward and backward relative to the door storage portion 10 in the opening and closing direction. The first door 20 is supported on the door storage portion 10 in a manner that allows it to move in the opening and closing direction. The second door 30 is supported on the first door 20 in a manner that allows it to move in the opening and closing direction. The first door 20 and the second door 30 are arranged in a manner that allows them to move forward and backward relative to both side surfaces of the door storage portion 10, respectively, but only the door on the right side is shown in the figure, and the door on the left side is omitted. In addition, the first door 20 and the second door 30 may also be arranged in a manner that allows them to move forward and backward only relative to either side of the door storage portion 10.

[0043] like Figure 2 and Figure 3 As shown, the first door 20 includes a plate-like member 20A and a pair of door frames 22 extending in the opening and closing direction. The plate-like member 20A is in the shape of a plate. The upper and lower ends of the plate-like member 20A are retained by the pair of door frames 22. The second door 30 includes a plate-like member 30A and a pair of door frames 32 extending in the opening and closing direction. The plate-like member 30A is in the shape of a plate. The upper and lower ends of the plate-like member 30A are retained by the pair of door frames 32.

[0044] The second door 30 includes a longitudinal frame 37, which is connected to a pair of door frames 32 and limits the movement of the plate-like member 30A in the opening and closing direction. The plate-like member 30A can be disassembled relative to the door frame 32. The plate-like member 30A can be disassembled by disassembling the longitudinal frame 37 extending in the vertical direction from the door frame 32 and pulling out the plate-like member 30A from the door frame 32. The first door 20 is also similar to the second door 30, and the plate-like member 20A can be disassembled relative to the door frame 22. The first door 20 includes a longitudinal frame 29, which is connected to a pair of door frames 22 and limits the movement of the plate-like member 20A in the opening and closing direction. The plate-like member 20A can be disassembled by disassembling the longitudinal frame 29 extending in the vertical direction from the door frame 22 and pulling out the plate-like member 20A from the door frame 22.

[0045] like Figure 4 As shown, the first door 20 and the second door 30 are doors that divide the platform 3 side and the track 2 side. The first upper protrusion 25 of the first door 20 is slidably engaged with the first upper track 11 provided in the door storage portion 10, and the first lower protrusion 26 is slidably engaged with the first lower track 12 provided in the door storage portion 10. The first door 20 is slidably held by the first upper track 11 and the first lower track 12. Therefore, the first door 20 can move relative to the door storage portion 10 in the opening and closing direction.

[0046] The second upper protrusion 27 of the second door 30 is slidably engaged with the second upper rail 35 provided on the first door 20, and the second lower protrusion 28 is slidably engaged with the second lower rail 36 provided on the first door 20. The second door 30 is slidably held by the second upper rail 35 and the second lower rail 36. Therefore, the second door 30 can move relative to the first door 20 in the opening and closing direction.

[0047] like Figure 5 As shown, the plate-like member 20A includes a transparent member 21, a contact member 23, and an elastic member 24. The transparent member 21 is in the shape of a plate, and can be a transparent member such as glass, resin, etc. that transmits light, or an opaque member. The door frame 22 and the contact member 23 are made of any one of iron, aluminum, and stainless steel. A track portion 22A extending in the opening and closing direction is provided on the door frame 22. In the thickness direction of the transparent member 21, the center P1 of the track portion 22A is located closer to the track 2 than the center P2 of the transparent member 21. As a result, the thickness T5 of the portion of the door frame 22 on the platform 3 side can be ensured.

[0048] The contact member 23 has an engaged portion 23A and a retaining portion 23B. The engaged portion 23A is a protruding portion extending in the opening and closing direction. The engaged portion 23A is engaged with the rail portion 22A in a manner that allows sliding in the opening and closing direction. The retaining portion 23B retains the upper end portion 21A and the lower end portion 21B of the transparent member 21. The contact member 23 is a member that presses the end portion of the transparent member 21 in a manner that prevents the end portion of the transparent member 21 from deviating, and is a member called a pressure member. The elastic member 24 is arranged between the transparent member 21 and the retaining portion 23B.

[0049] The cross section of the holding portion 23B is U-shaped. A gap W1 between the first portion 23B1 of the holding portion 23B on the platform 3 side and the transmissive member 21 is narrower than a gap W2 between the second portion 23B2 of the holding portion 23B on the rail 2 side and the transmissive member 21 (W1<W2).

[0050] The cross section of the elastic member 24 is U-shaped. The elastic member 24 is disposed between the transparent member 21 and the holding portion 23B in the thickness direction of the transparent member 21 so as to sandwich the transparent member 21. The thickness T1 of the first portion 24A of the elastic member 24 located on the platform 3 side is thinner than the thickness T2 of the second portion 24B of the elastic member 24 located on the rail 2 side (T1<T2).

[0051] The folding portion 24C is provided at the second portion 24B of the elastic member 24 located on the track 2 side. The folding portion is not provided at the first portion 24A of the elastic member 24 located on the platform 3 side. The transparent member 21 is inserted in the upward direction relative to the contact member 23 in the up-down direction orthogonal to the opening and closing direction and the thickness direction. The folding portion 24C extends in the direction of removing the transparent member 21 from the contact member 23, that is, in the downward direction. There are a plurality of folding portions 24C, which extend obliquely downward. If the folding portion 24C is inserted into the contact member 23, it contacts the contact member 23 and bends downward. If the transparent member 21 is to be pulled out from the contact member 23, the friction resistance between the contact member 23 and the folding portion 24C becomes large, and the folding portion 24C functions as an anti-detachment portion.

[0052] A positioning portion 24D is provided on the upper portion of the elastic member 24. The positioning portion 24D positions the elastic member 24 and the retaining portion 23B in the up-down direction perpendicular to the opening and closing direction and the thickness direction of the plate-like member 20A. The positioning portion 24D is a plurality of convex portions protruding upward. When the transparent member 21 is inserted into the contact member 23, the top end of the positioning portion 24D abuts against the retaining portion 23B of the contact member 23, thereby positioning. In addition, by bending the positioning portion 24D, it is possible to allow a slight error in the up-down length of the transparent member 21 relative to the door frame 22.

[0053] like Figure 4As shown, the upper end 21A and the lower end 21B of the plate-like member 20A parallel to the opening and closing direction are inserted into a pair of upper and lower door frames 22. The contact member 23 and the elastic member 24 having the same shape at the upper end 21A and the lower end 21B of the plate-like member 20A are installed at the upper end 21A and the lower end 21B parallel to the opening and closing direction.

[0054] like Figure 6 As shown, the plate-like member 30A includes a transparent member 31, a contact member 33, and an elastic member 34. The transparent member 31 is in the shape of a plate, and can be a transparent member such as glass or resin that transmits light, or an opaque member. The door frame 32 and the contact member 33 are made of any one of iron, aluminum, and stainless steel. The door frame 32 is provided with a track portion 32A extending in the opening and closing direction. In the thickness direction of the transparent member 31, the center P3 of the track portion 32A is located closer to the track 2 than the center P4 of the transparent member 31. As a result, the thickness T6 of the portion of the door frame 32 on the platform 3 side can be ensured.

[0055] The contact member 33 has an engaged portion 33A and a holding portion 33B. The engaged portion 33A is a protrusion extending in the opening and closing direction. The engaged portion 33A is engaged with the rail portion 32A in a manner that allows sliding in the opening and closing direction. The holding portion 33B holds the upper end portion 31A and the lower end portion 31B of the permeable member 31. The contact member 33 is a member that presses the end portion of the permeable member 31 in a manner that prevents the end portion of the permeable member 31 from deviating, and is a member called a pressure member. The elastic member 34 is arranged between the permeable member 31 and the holding portion 33B.

[0056] The cross section of the holding portion 33B is U-shaped. A gap W3 between the first portion 33B1 of the holding portion 33B on the platform 3 side and the transmissive member 31 is narrower than a gap W4 between the second portion 33B2 of the holding portion 33B on the rail 2 side and the transmissive member 31 (W3<W4).

[0057] The cross section of the elastic member 34 is U-shaped. The elastic member 34 is disposed between the transparent member 31 and the holding portion 33B in the thickness direction of the transparent member 31 so as to sandwich the transparent member 31. The thickness T3 of the first portion 34A of the elastic member 34 located on the platform 3 side is thinner than the thickness T4 of the second portion 34B of the elastic member 34 located on the rail 2 side (T3<T4).

[0058] The second portion 34B of the elastic member 34, which is located on the track 2 side, is provided with a folding portion 34C. The first portion 34A of the elastic member 34, which is located on the platform 3 side, is not provided with a folding portion. The transparent member 31 is inserted in the upward direction relative to the contact member 33. The folding portion 34C extends in the direction opposite to the direction in which the transparent member 31 is inserted into the contact member 33, that is, in the downward direction. There are a plurality of folding portions 34C, which extend obliquely downward. If the folding portion 34C is inserted into the contact member 33, it contacts the contact member 33 and bends downward. If the transparent member 31 is to be pulled out from the contact member 33, the frictional resistance between the contact member 33 and the folding portion 34C becomes large, and the folding portion 34C functions as an anti-detachment portion.

[0059] A positioning portion 34D is provided on the upper portion of the elastic member 34. The positioning portion 34D positions the elastic member 34 and the retaining portion 33B in the up-down direction orthogonal to the opening and closing direction and the thickness direction of the plate-like member 30A. The positioning portion 34D is a plurality of convex portions protruding upward. When the transparent member 31 is inserted into the contact member 33, the top end of the positioning portion 34D abuts against the retaining portion 33B of the contact member 33, thereby positioning. In addition, by bending the positioning portion 34D, it is possible to allow a slight error in the up-down length of the transparent member 31 relative to the door frame 32.

[0060] like Figure 4 As shown, the upper end 31A and the lower end 31B of the transparent member 31 parallel to the opening and closing direction are inserted into a pair of upper and lower door frames 32. The contact member 33 and the elastic member 34 having the same shape at the upper end 31A and the lower end 31B of the transparent member 31 are installed. The contact member 23 of the first door 20 and the contact member 33 of the second door 30 have the same shape. The elastic member 24 of the first door 20 and the elastic member 34 of the second door 30 have the same shape. Therefore, the first door 20 and the second door 30 are installed using the contact member and the elastic member having the same shape at the first door 20 and the second door 30.

[0061] like Figure 7 As shown, a longitudinal frame 29 and an elastic member 24 are provided at the door head and door tail of the first door 20, respectively. The longitudinal frame 29 extends in the up-down direction of the transparent member 21. The longitudinal frame 29 has a recess 29A for the end of the transparent member 21 perpendicular to the opening and closing direction to fit in. The elastic member 24 is arranged between the transparent member 21 and the recess 29A. The elastic member 24 is a member of the same shape as the elastic member 24 arranged between the transparent member 21 and the contact member 23. The transparent member 21 is inserted relative to the longitudinal frame 29 in the opening and closing direction. The contact member 23 is not provided between the longitudinal frame 29 and the elastic member 24. The longitudinal frame 29 is fixed to the door frame 22 by screws. In addition, the longitudinal frame 29 can also be connected to the door frame 22 by a snap-fit ​​structure instead of screws.

[0062] like Figure 8 As shown, a longitudinal frame 37 and an elastic member 34 are provided at the door head and door tail of the second door 30, respectively. The longitudinal frame 37 extends in the up-down direction of the transparent member 31. The longitudinal frame 37 has a recess 37A for the end of the transparent member 31 perpendicular to the opening and closing direction to be fitted. The elastic member 34 is arranged between the transparent member 31 and the recess 37A. The elastic member 34 is a member of the same shape as the elastic member 34 arranged between the transparent member 31 and the contact member 33. The transparent member 31 is inserted relative to the longitudinal frame 37 in the opening and closing direction. The contact member 33 is not provided between the longitudinal frame 37 and the elastic member 34. A door head member 38 is provided in the longitudinal frame 37 of the door head. A buffer member 39 is installed at the top of the door head member 38. The door head member and the buffer member 39 are parts that mitigate the impact caused by contact with the opposite door or obstacle. The longitudinal frame 37 is fixed to the door frame 32 by screws. In addition, the longitudinal frame 37 can also be connected to the door frame 32 by a snap-fit ​​structure instead of screws.

[0063] Next, refer to Figures 9 to 14 Next, a method for replacing the transparent member 31 of the second door 30 of the platform door device 5 configured as described above will be described. Here, the operation of replacing the transparent member 31 of the second door 30 with another transparent member 31 will be described. The transparent member 21 of the first door 20 can also be replaced by the same operation.

[0064] First, if Figure 2 As shown, the operator performs the release step. The operator removes the vertical frame 37 from the pair of door frames 32 to release the restriction on the movement of the plate-like member 30A in the opening and closing direction. The vertical frame 37 can be removed from the door frame 32 by loosening and removing the screws.

[0065] like Figure 3 As shown, the operator performs the pulling-out step. The operator pulls out the plate-like member 30A from the rail portions 32A of the pair of door frames 32. The contact member 33 can slide relative to the rail portions 32A of the door frames 32, so the plate-like member 30A can be easily pulled out in the opening and closing direction.

[0066] The operator performs the disassembly step. The operator disassembles the contact member 33 and the elastic member 34 from the plate-shaped member 30A. The contact member 33 held by the permeable member 31 is disassembled upward. The elastic member 34 held by the permeable member 31 is disassembled further upward.

[0067] like Fig. 9As shown, the operator takes the newly installed permeable member 31 and performs the installation step. The operator installs the elastic member 34 removed in the disassembly step to each end of the permeable member 31. The elastic member 34 can be a member that has been installed in the already installed permeable member 31, or a new member can be used. The elastic member 34 is embedded in a manner of clamping the permeable member 31. The elastic member 34 installed at the upper end 31A of the permeable member 31 is embedded from the top of the permeable member 31. The elastic member 34 installed at the lower end 31B of the permeable member 31 is embedded from the bottom of the permeable member 31. The elastic member 34 installed at the door tail end 31C of the permeable member 31 is embedded from the left side of the permeable member 31. The elastic member 34 installed at the door head end 31D of the permeable member 31 is embedded from the right side of the permeable member 31.

[0068] like Fig.10 As shown in the figure, the length of the elastic member 34 installed at the upper end 31A and the lower end 31B of the permeable member 31 is extended to the two corners of the permeable member 31. The length of the elastic member 34 installed at the door tail end 31C and the door head end 31D of the permeable member 31 is the length that avoids the elastic member 34 installed at the upper end 31A and the lower end 31B of the permeable member 31.

[0069] like Fig.11 As shown, the elastic member 34 is fitted with the permeable member 31. The permeable member 31 is sandwiched between the first portion 34A and the second portion 34B of the elastic member 34. The upper end portion 31A and the lower end portion 31B of the permeable member 31 are in contact with the inner bottom surface of the elastic member 34.

[0070] Next, if Fig.12 As shown, the operator performs the holding step. The operator holds the transparent member 31 equipped with the elastic member 34 on the holding portion 33B of the contact member 33 removed in the disassembly step. The contact member 33 may use a member that has been installed in the existing transparent member 31, or a new member may be used. The transparent member 31 equipped with the elastic member 34 is inserted into the holding portion 33B of the contact member 33. At this time, the folding portion 34C of the elastic member 34 contacts the second portion 33B2 of the holding portion 33B and is inserted while being bent. And, the insertion is stopped when the positioning portion 34D of the elastic member 34 contacts the inner bottom surface of the holding portion 33B. The transparent member 31 is clamped by the first portion 33B1 and the second portion 33B2 of the holding portion 33B. The contact member 33 is difficult to be pulled out relative to the elastic member 34.

[0071] Next, if Fig.13As shown, the operator performs the insertion step. The operator inserts the engaged portion 33A of the contact member 33 holding the transparent member 31 into the track portion 32A of the door frame 32 in the opening and closing direction. The door frame 32 and the contact member 33 are made of any one of iron, aluminum, and stainless steel. Therefore, the materials with higher rigidity slide against each other, and the contact member 33 moves relatively easily relative to the door frame 32. If the door tail end portion 31C of the transparent member 31 moves to the door tail in the opening and closing direction, it is inserted into the recessed portion 37A of the longitudinal frame 37 at the door tail. The door tail end portion 31C of the transparent member 31 is held by the longitudinal frame 37 at the door tail.

[0072] Next, if Fig.14 As shown, the operator performs the fitting step. The operator fits the door head longitudinal frame 37 with the door head end 31D of the transparent member 31. The door head end 31D of the transparent member 31 is inserted into the recess 37A of the door head longitudinal frame 37. The door head end 31D of the transparent member 31 is held by the door head longitudinal frame 37. The door head longitudinal frame 37 is screwed to the upper and lower door frames 32. Therefore, a new transparent member 31 can be installed on the second door 30. In addition, the transparent member 31 can be removed by performing the reverse sequence.

[0073] Next, the effects of this embodiment will be described.

[0074] (1) When replacing the transmissive members 21 and 31, the plate-shaped members 20A and 30A can be removed from the door frames 22 and 32 by sliding the plate-shaped members 20A and 30A from the door frames 22 and 32 in the opening and closing directions. Therefore, only the transmissive members 21 and 31 can be replaced.

[0075] (2) The thicknesses T1 and T3 of the first portions 24A and 34A of the elastic members 24 and 34 on the platform 3 side are thinner than the thicknesses T2 and T4 of the second portions 24B and 34B of the elastic members 24 and 34 on the rail 2 side. Therefore, the height of the surface of the transparent members 21 and 31 on the platform 3 side formed by the elastic members 24 and 34 can be suppressed, and fingers can be prevented from being caught when the first door 20 and the second door 30 are opened.

[0076] (3) Due to the folded portions 24C and 34C provided on the elastic members 24 and 34, it is difficult to pull out the transparent members 21 and 31 in the direction of removal from the contact members 23 and 33. In addition, the folded portions 24C and 34C are provided only on the second portions 23B2 and 33B2 of the holding portions 23B and 33B on the rail 2 side. Therefore, the thicknesses T2 and T4 of the holding portions 23B and 33B are increased only on the rail 2 side by the folded portions 24C and 34C, and the height of the surface of the transparent members 21 and 31 on the platform 3 side formed by the elastic members 24 and 34 can be suppressed, and fingers can be suppressed from being caught when the first door 20 and the second door 30 are opened.

[0077] (4) The gaps W1 and W3 between the first portion 23B1 of the holding portion 23B located on the platform 3 side and the transparent members 21 and 31 are narrower than the gaps W2 and W4 between the second portion 23B2 of the holding portion 23B located on the rail 2 side and the transparent members 21 and 31. Therefore, the height of the surface of the transparent members 21 and 31 formed by the contact members 23 and 33 on the platform 3 side can be suppressed, and fingers can be prevented from being caught when the first door 20 and the second door 30 are opened.

[0078] (5) The centers P1 and P3 of the rail portions 22A and 32A are located closer to the rail 2 than the centers P2 and P4 of the transparent members 21 and 31. Therefore, the thicknesses T5 and T6 of the portions of the door frames 22 and 32 on the platform 3 side can be ensured, thereby improving the strength of the door frames 22 and 32 and making manufacturing easier.

[0079] (6) When the elastic members 24 and 34 are inserted into the retaining portions 23B and 33B of the contact members 23 and 33, the positions of the elastic members 24 and 34 in the retaining portions 23B and 33B are determined in the up and down directions by the positioning portions 24D and 34D, making it easier to position the transparent members 21 and 31 relative to the contact members 23 and 33.

[0080] (7) The vertical frames 29 and 37 that restrict movement of the permeable members 21 and 31 in the opening and closing directions are connected to the pair of door frames 22 and 32. Therefore, by removing the vertical frames 29 and 37 from the door frames 22 and 32, the permeable members 21 and 31 can be moved in the opening and closing directions.

[0081] (8) The permeable members 21 and 31 are fitted into the recesses 29A and 37A of the vertical frames 29 and 37 via the elastic members 24 and 34, so it is easy to attach the permeable members 21 and 31 to the vertical frames 29 and 37. Therefore, only the permeable members 21 and 31 can be replaced.

[0082] (9) The door frames 22, 32 and the contact members 23, 33 are made of any of iron, aluminum, and stainless steel. Therefore, the sliding between the materials having high rigidity makes it easy to attach and detach the contact members 23, 33 to and from the door frames 22, 32.

[0083] (10) Since the contact members 23, 33 and the elastic members 24, 34 having the same shape at the upper and lower ends and the left and right ends are attached to the transmissive members 21, 31, it is not necessary to prepare a plurality of types of contact members 23, 33 and elastic members 24, 34.

[0084] (11) Since the contact members 23, 33 and the elastic members 24, 34 having the same shape are attached to the transparent members 21, 31 in the first door 20 and the second door 30, it is not necessary to prepare a plurality of contact members 23, 33 and elastic members 24, 34.
