Specifically, the door pocket side support portion 24 supports the sliding door 10 from below vertically by the wheel 24A coming into contact with the rail 15A of the guide support portion 15L.

  FIG. 7 shows the internal structure of the split door pocket body 20E of the intermediate door pocket body 20C. In the intermediate door pocket body 20C, the split door pocket bodies 20D, 20F, 20G (see FIG. 1) have the same configuration as the split door pocket body 20E of FIG. 7. The case 26 of the split door pocket body 20E is fixed to the platform P by, for example, bolts (not shown). Each of the end walls 26A of the case 26 in the opening / closing direction ZA is formed with a through hole 26B penetrating in the opening / closing direction ZA. The sliding door 10 moves inside the intermediate door pocket body 20C through the through hole 26B.

  A support plate 27 is fixed to the platform P on the home side in the case 26 by, for example, bolts (not shown). On the support plate 27, a door pocket side support portion 28, which is an example of a sliding door support portion and is capable of supporting the sliding door 10 from vertically below, is provided. The door pocket side support portion 28 has the same structure as the door pocket side support portion 24, and has wheels 28A and wheel support portions 28B. The upper end of the wheel 28A is located in the through hole 26B in the height direction ZB. The door pocket side support portion 28 is located at the center of the divided door pocket body 20E in the opening / closing direction ZA. As shown in FIG. 7, the door pocket side support portion 28 supports the center of the sliding door 10 in the thickness direction. More specifically, the door pocket side support portion 28 supports the sliding door 10 from vertically below by the wheel 28A coming into contact with the lower surface of the rail 15A of the guide support portion 15L. The split door pocket body 20D has the same configuration as the split door pocket body 20E except that the split door pocket body 20D is not provided.

  As described above, one door pocket side support portion 24 and three door pocket side support portions 28 are provided in the door pocket 20 (see FIG. 1). The door pocket side support portions 24 and 28 are arranged at intervals in the opening / closing direction ZA. The position of the door pocket side support portions 24, 28 in the opening / closing direction ZA can be arbitrarily changed. Further, as shown in FIG. 11, the door pocket side support portion 28 gradually decreases in height in the opening direction, and the height of the door pocket side support portion 24 is the highest among the door pocket side support portions 28. It is lower than the lower door pocket support 28.

The detailed internal structure of the end horizontal support 30 will be described with reference to FIGS. 8 and 9.
As shown in FIGS. 8A and 8B, the case 31 of the end horizontal support 30 is fixed to the platform P via the substrate 32 by, for example, bolts (not shown). An opening 33A as shown by a chain double-dashed line in FIG. 8B is formed on the end wall 33 of the case 31 in the opening direction. In the case 31, a door stop 34, a pair of upper horizontal support portions 35U, and a pair of lower horizontal support portions 35L are housed.

  As shown in FIG. 9, the door stop 34 is provided on the end wall 36 of the case 31 in the closing direction. The door stop 34 regulates the movement of the sliding door 10 in the closing direction by the contact of the door end of the sliding door 10 in the opening / closing direction ZA. In FIG. 9, the crosspiece 12U is shown as a plan view for convenience.

  As shown in FIG. 8B, the pair of upper horizontal support portions 35U are located on both sides of the upper crosspiece 12U in the thickness direction of the sliding door 10, and the pair of lower horizontal support portions 35L are the thickness of the sliding door 10. It is located on both sides of the lower crosspiece 12L in the direction. As shown in FIG. 9, in the state where the door tip of the sliding door 10 is inserted into the end horizontal support portion 30, the surface 12X of the crosspiece 12U and the upper horizontal support portion 35U have a slight gap in the thickness direction of the sliding door 10. Is formed, and a slight gap is formed between the back surface 12Y of the crosspiece 12U and the upper horizontal support portion 35U in the thickness direction of the sliding door 10. The relationship between the crosspiece 12L and the lower horizontal support portion 35L is similar to the relationship between the crosspiece 12U and the upper horizontal support portion 35U. Therefore, when the door tip of the sliding door 10 is bent toward the home side or the track side, the pair of upper horizontal support portions 35U contacts the crosspiece 12U, so that the pair of upper horizontal support portions 35U moves the crosspiece 12U toward the home side and the track side. Can be supported from. Also, when the door tip of the sliding door 10 bends toward the home side or the track side, the pair of lower horizontal support portions 35L contacts the crosspiece 12L, so that the pair of lower horizontal support portions 35L connects the crosspiece 12L to the home side and the track side. Can be supported from.

With reference to FIG. 10 and FIG. 11, the operation of the sliding door opening / closing device 1 and the supporting states of the door side support portion 16 and the door pocket side support portions 24, 28 will be described together with the operational effects thereof.
As shown in FIG. 10A, when the position of the sliding door 10 is the fully open position, the door tip of the sliding door 10 is located near the guide member 15B of the guide support portions 15U and 15L. Therefore, the tip of the sliding door 10 is less likely to bend vertically downward due to the weight of the sliding door 10. At this time, the wheels 16A of the door-side support portion 16 are located above the installation surface P1 of the platform P with a space provided therebetween. Therefore, the door-side support portion 16 is in a state of not supporting the sliding door 10 from vertically below.

  On the other hand, when the sliding door 10 is in the fully open position, the trailing edge of the sliding door 10 housed in the door pocket 20 is located far from the guide member 15B of the guide support portions 15U and 15L. Therefore, the trailing edge of the sliding door 10 is likely to bend vertically downward due to the weight of the sliding door 10. In this respect, in the sliding door opening / closing device 1, when the sliding door 10 is in the fully open position, the sliding door 10 is located on the door pocket side support portion 24 and each door pocket side support portion 28 provided on the door pocket 20. That is, when the sliding door 10 is in the fully open position, the door pocket side support portion 24 and each door pocket side support portion 28 are in a state of supporting the sliding door 10 from vertically below. Therefore, it is possible to prevent the sliding door 10 housed in the door bag 20 from bending vertically downward due to its own weight.

  Then, as shown in FIG. 10B, when the sliding door 10 moves in the closing direction, the amount of bending of the sliding door 10 vertically downward due to its own weight is large because the door tip of the sliding door 10 is separated from the guide member 15B. Become. Therefore, although the door-side support portion 16 approaches the installation surface P1, the wheels 16A are not in contact with the installation surface P1. Therefore, the door-side support portion 16 is maintained in a state where it does not support the sliding door 10 from vertically below.

  On the other hand, the sliding door 10 housed in the door pocket 20 is located on the two door pocket side support portions 28 on the closing direction side, and on the door pocket side support portion 24 and the door pocket side support portion 28 located in the most open direction. Not not. Therefore, the two door pocket side support portions 28 on the closing direction side maintain the state of supporting the sliding door 10 from vertically below, while the door pocket side support portion 24 and the door pocket side support portion 28 located in the most open direction are the sliding doors. It is changed to the state where 10 is not supported from below vertically. As described above, since the door pocket side support portion 28 supports the sliding door 10 housed in the door bag 20 from vertically below, it is possible that the sliding door 10 housed in the door bag 20 bends vertically downward due to its own weight. Can be suppressed.

  Then, as shown in FIG. 10C, when the sliding door 10 further moves in the closing direction, the sliding door 10 further moves away from the guide member 15B, so that the sliding door 10 bends vertically downward due to its own weight. Will be more. At this time, the wheel 16A of the door-side support part 16 contacts the installation surface P1. That is, the door-side support portion 16 is changed to a state of supporting the sliding door 10 from vertically below. For this reason, it is possible to prevent the door tip of the sliding door 10 from bending vertically downward due to its own weight.

  On the other hand, the sliding door 10 is not located on the door pocket side support portion 24 and each door pocket side support portion 28. Therefore, the two door pocket side support portions 28 in the closing direction are changed to a state where they do not support the sliding door 10 from vertically below, and the door pocket side support portion 24 and the door pocket side support portion 28 located in the most open direction support the sliding door 10. The state of not supporting from below is maintained. The trailing edge of the sliding door 10 housed in the door bag 20 is located near the guide member 15B. For this reason, even if the door pocket side support portions 24 and 28 do not support the sliding door 10 housed in the door bag 20 from vertically below, the sliding door 10 housed in the door bag 20 is difficult to bend vertically downward.

  Then, as shown in FIG. 10D, when the position of the sliding door 10 is the fully closed position, the door tip of the sliding door 10 is inserted into the end horizontal support portion 30. At this time, the upper horizontal support portion 35U and the lower horizontal support portion 35L of the end horizontal support portion 30 can support the sliding door 10 in the thickness direction of the sliding door 10. It should be noted that the door side support portion 16 is maintained in a state of supporting the sliding door 10 from below vertically, and the door bag side support portion 24 and each door bag side support portion 28 is maintained in a state of not supporting the sliding door 10 from below vertically. It

  As described above, the door-side support portion 16 can be in a state of supporting the sliding door 10 from below in the vertical direction or a state of not supporting the sliding door 10 from below in the vertical direction, depending on the position of the sliding door 10 in the opening / closing direction ZA. Further, the door pocket side support portion 24 and each door pocket side support portion 28 are in a state of supporting the sliding door 10 from below in the vertical direction or do not support the sliding door 10 from below in accordance with the position of the sliding door 10 in the opening / closing direction ZA. It can be in a state. Therefore, the sliding door 10 can be restrained from bending vertically downward due to its own weight, and the sliding door 10 can be compared with a structure in which the door-side support portion 16 and the door-bag-side support portions 24 and 28 are always in contact with the sliding door 10. The movement of 10 in the opening / closing direction ZA becomes smooth.

  In particular, if it is assumed that the door support 16 supports the sliding door 10 from below vertically in the vicinity of the guide supports 15U and 15L, for example, there are obstacles such as pebbles on the installation surface P1 near the door bag 20, When the support portion 16 rides over the obstacle, the sliding door 10 tries to move upward, and an excessive force is applied to the guide support portions 15U and 15L. As a result, the rail 15A becomes immovable with respect to the guide member 15B, and the sliding door 10 may not move in the opening / closing direction ZA.

  In that respect, in the sliding door opening / closing device 1 of the present embodiment, as shown in FIG. 10C, since the door side support portion 16 supports the sliding door 10 from a vertically lower position at a position far from the guide support portions 15U and 15L, Even if the door-side support portion 16 rides over an obstacle on the installation surface P1, it is possible to prevent excessive force from being applied to the guide support portions 15U and 15L. Therefore, the sliding door 10 can move smoothly in the opening / closing direction ZA.

  By the way, since the sliding door 10 housed in the door bag 20 cannot be visually recognized from the outside of the door bag 20, deterioration of the aesthetic appearance of the sliding door 10 can be avoided even if the sliding door 10 bends vertically downward. Further, as the sliding door 10 moves in the opening direction, the trailing edge of the sliding door 10 housed in the door pocket 20 easily bends vertically downward due to the weight of the sliding door 10. For this reason, the sliding door 10 housed in the door pocket 20 increases in the amount of bending vertically downward as it moves in the opening direction. Therefore, if it is assumed that the sliding door 10 housed in the door bag 20 is not supported by the door bag side support portion 28 from the vertically lower side, the sliding door 10 housed in the door bag 20 excessively bends vertically downward. As a result, when the sliding door 10 is opened, the trailing edge of the sliding door 10 may collide with the end wall 26A of the intermediate door bag body 20C or the end wall 23A of the open end side door bag body 20B (see FIG. 11).

  On the other hand, in a configuration in which the sliding door 10 is supported from below vertically by the door pocket side support portions 24 and 28, it is assumed that the heights of the three door bag side support portions 28 and the door pocket side support portions 24 from the installation surface P1 are all constant. In some cases, the lower end of the trailing edge of the sliding door 10 is located below the upper end surface of the wheels 28A, 24A of the door pocket side support portion 28 and the door pocket side support portion 24 on the opening direction side. In this case, the trailing edge of the sliding door 10 may collide with the wheels 28A and 24A in the opening / closing direction ZA, and the sliding door 10 may be impacted and the sliding door 10 may not move smoothly in the opening direction.

  Therefore, in the sliding door opening / closing device 1 of the present embodiment, as shown in FIG. 11, the heights of the three door pocket side support portions 28 and the door pocket side support portions 24 from the installation surface P1 become lower toward the opening direction. ing. Therefore, when the sliding door 10 moves in the opening direction, the sliding door 10 comes into contact with the upper ends of the wheels 28A, 24A, and thus is unlikely to collide with the wheels 28A, 24A in the opening / closing direction ZA. Therefore, the impact on the sliding door 10 is suppressed, and the sliding door 10 can move smoothly in the opening direction.

  Further, as the sliding door 10 moves in the opening direction, the amount of downward bending of the sliding door 10 housed in the door bag 20 in the vertical direction gradually increases. Since it is supported, the sliding door 10 housed in the door pocket 20 is prevented from excessively bending vertically downward. Therefore, it is possible to prevent the trailing edge of the sliding door 10 from colliding with the end wall 26A of the intermediate door pocket body 20C and the end wall 23A of the open end side door pocket body 20B.

According to the sliding door opening / closing device 1 of the present embodiment, the following effects can be obtained in addition to the above-described effects.
(1) The drive unit 40 provided in the door pocket 20 is connected to the trailing edge of the sliding door 10, so that the drive unit 40 is provided only in a part of the opening / closing direction ZA of the sliding door 10. Therefore, the light transmitting portion 11 can be supported by the pair of crosspieces 12U and 12L provided at both ends in the height direction ZB. Therefore, as compared with the configuration in which the drive unit 40 is arranged at the center of the sliding door 10 in the height direction ZB, it is possible to increase the area of the light transmitting unit 11 with respect to the sliding door 10. Therefore, the appearance of the sliding door 10 is improved.

  (2) Since the translucent plate 11A is arranged on the surface 12X side of the crosspieces 12U and 12L, the step difference between the surface 11X of the translucent plate 11A and the surface 12X of the crosspieces 12U and 12L becomes small. Therefore, the appearance of the sliding door 10 is improved.

  (3) Since the dimension of the translucent plate 11A in the thickness direction is smaller than the dimension of the crosspieces 12U and 12L in the thickness direction, the translucent plate 11A is arranged on the front surface 12X side of the crosspieces 12U and 12L. A space S1 surrounded by the back surface 11Y of 11A and the back surfaces 12Y of the crosspieces 12U and 12L is formed. The guide support portion 15U is arranged in the space S1. Therefore, the space S1 can be effectively utilized. Further, the dimension of the crosspieces 12U and 12L in the thickness direction and the dimension of the door pocket 20 in the thickness direction are reduced as compared with the configuration in which the translucent plate 11A is arranged on the back surface 12Y side of the crosspieces 12U and 12L. be able to.

  (4) A door-side support portion 16 capable of supporting the sliding door 10 from vertically below is provided at the door end of the sliding door 10. Further, the door pocket 20 is provided with door pocket side support portions 24 and 28 capable of supporting the sliding door 10 from vertically below. Therefore, it is possible to prevent the crosspieces 12U and 12L from increasing in size in order to reduce the amount of bending of the sliding door 10 in the vertically downward direction. Therefore, the dimensions of the crosspieces 12U and 12L in the height direction ZB can be reduced, and the area of the light transmitting portion 11 can be increased. Further, since the dimensions of the crosspieces 12U and 12L in the thickness direction can be reduced, the dimension of the sliding door 10 in the thickness direction can be reduced.

  (5) Since the rails 15A of the guide support portions 15U and 15L are provided in the sliding door 10, the door pocket 20 includes a plurality of door pockets, that is, a closed end side door pocket body 20A and an open end side door pocket body 20B regardless of the length of the rail 15A. , And the intermediate door pocket body 20C. In addition, since the rail 15A is provided on the crosspieces 12U and 12L, the area of the light transmitting portion 11 is made larger than that of the configuration in which the rail 15A is provided between the crosspieces 12U and 12L in the height direction ZB. be able to.

  (6) The translucent part 11 is configured by arranging a plurality of translucent plates 11A in the opening / closing direction ZA. Therefore, as compared with the case where the translucent portion 11 is manufactured as a single translucent plate, the translucent portion 11 is easier to manufacture. In addition, if one of the light-transmitting plates 11A of the light-transmitting part 11 is damaged, the damaged light-transmitting plate 11A may be replaced, and the entire light-transmitting part 11 need not be replaced. Good. Therefore, the replacement cost of the light transmitting unit 11 can be reduced.

(7) When the sliding door opening / closing device is installed on the platform P, if the door bag is long in the opening / closing direction, it becomes difficult to carry the door bag and the platform P is installed by the large construction machine when the door bag is installed on the platform P. It is necessary to suspend the door pocket from the outside of the and transport it to the installation site. As described above, it takes time and cost to install the door pocket on the platform P. Further, the hanging tool may deform the door pocket.
In that respect, the sliding door opening / closing device 1 of the present embodiment is configured such that the door pocket 20 is configured by a plurality of door pockets such as the closed end side door pocket body 20A, the open end side door pocket body 20B, and the intermediate door pocket body 20C. Can be disassembled and carried. Therefore, the door bag 20 can be easily carried, and when the door bag 20 is installed on the platform P, the door bags 20A to 20C can be directly carried by a trolley to the installation place of the platform P. Therefore, since the door pocket 20 can be carried to the installation place without using a construction machine, the time and cost required for the work of installing the door pocket 20 on the platform P can be suppressed.
In addition, since the intermediate door pocket body 20C is divided into a plurality of door pocket bodies of four divided door pocket bodies 20D to 20G, the intermediate door pocket body 20C can be disassembled and carried, and can be carried by a dolly to the installation location of the platform P. You can Therefore, it is possible to further suppress the time and cost required for the work of installing the door pocket 20 on the platform P.

  (8) The drive unit 40 includes the drive rotary body 42, the driven rotary body 43, and the transmission member 44, and is arranged on the home side with respect to the drive side support body 60 and the driven side support body 70 in the door pocket 20. . Accordingly, the worker can perform the mounting work and maintenance of the drive unit 40 from the home side of the door pocket 20. Further, as compared with a structure in which a toothed belt 233 that meshes with a toothed pulley 231A connected to an electric motor 231 is provided in the sliding door 210 as in the sliding door opening / closing device 200 shown in FIG. Since the work of attaching the attached belt is omitted, the drive unit 40 can be easily assembled.

  (9) Since the translucent plate 11A of the translucent part 11 is configured to sandwich a glass plate between translucent resin plates, it is assumed that the translucent plate 11A is formed of a glass plate having the same thickness as the translucent plate 11A. The light-transmitting portion 11 can be made lighter than the configuration described above. Therefore, the sliding door 10 can be reduced in weight.

  (10) The door pocket side support portions 24 and 28 can support the rail 15A of the guide support portion 15L. Therefore, since the door pocket side support portions 24, 28 support the rail 15A having high flatness accuracy, the sliding door 10 moves in the opening / closing direction ZA in a state in which at least one of the door pocket side support portions 24, 28 supports the rail 15A.
