In other words, the suspension base (fixed body mounting portion) 44 located at the side end of the upper and lower opening / closing plate 42 is connected to the truss machine screw (mounting tool) 45, the spacer collar 46 and the washer 47, It is attached to the fixed side attached portion 25 of the fixed body 22 so as to be rotatable about a horizontal axis (rotation fulcrum) 48 (see FIG. 5).

  Further, the opening / closing plate 42 on the front end side in the closing direction of the opening / closing body 41, that is, only the both ends in the left-right direction of the opening / closing plate 42 positioned at the lower end of the opening / closing body 41 when the opening 3 is fully closed, for example, The movable side attached portion 35 is rotatably attached. In other words, the endless body mounting portion 50 located at the side end of the opening / closing plate 42 at the lower end (front end in the closing direction) is a truss machine screw (mounting tool) 51, a spacer collar 52, a roller 53, a guide collar 54, a connecting arm 55, and It is attached to the movable side attached portion 35 of the endless body 31 through a washer 56 so as to be rotatable about a shaft portion (rotation fulcrum) 58 in the left-right direction (see FIG. 5).

  Here, each open / close plate 42 is larger and more rigid than a conventional shutter slat, and is formed of a metal plate such as an aluminum plate or a steel plate. The open / close plate 42 includes, for example, an open / close member (louver) 61 made of a rectangular plate bent at a plurality of locations, and arm-shaped side end members made of a long plate material and fixed to both left and right ends of the open / close member 61 ( Louver end) 62. The upper end portion of the side end member 62 protrudes upward from the upper end portion of the opening / closing member 61. However, only in the upper end opening / closing plate 42, the upper end portion of the side end member 62 does not protrude upward from the upper end portion of the opening / closing member 61. That is, the upper opening / closing member 61 has a different shape from the remaining opening / closing members 61 other than the upper opening / closing member 61, and an extension plate portion 61a is connected to the upper end of the upper opening / closing member 61 (see FIG. 4). Note that the upper end portions of the side end members 62 of the upper opening / closing plate 42 serve as the suspension base portion 44. An upper end portion of both side end members 62 of the lower end opening / closing plate 42 is an endless body attaching portion 50.

  Each open / close plate 42 is rotatable in the vertical direction around one end in the plate surface direction (one end in the longitudinal direction in side view) of the open / close plate 42. That is, the upper open / close plate 42 is rotatable in the vertical direction about the axis (fixed shaft) 48 at one end in the plate surface direction of the open / close plate 42. The opening / closing plate 42 at the lower end is rotatable in the vertical direction about an axis (movable shaft) 58 at one end in the plate surface direction of the opening / closing plate 42. The intermediate opening / closing plate 42 other than the upper and lower ends is rotatable in the vertical direction about an axis (movable shaft) 60 at one end in the plate surface direction of the opening / closing plate 42. The plate surface direction of the open / close plate 42 is the short direction of the open / close plate 42 having a rectangular shape.

  As shown in FIG. 2, the outer circumferences of shafts 58 and 60, which are a plurality of movable shafts that move in the vertical direction when the opening / closing body 41 moves (during the opening / closing operation), are respectively A cylindrical roller 53 and a guide collar 54 are rotatably attached. The roller 53 guided by the guide recess 11 of the guide body 5 is fitted in the guide recess 11 so as to be movable in the vertical direction. That is, the guide recess 11 of the guide body 5 guides the roller 53 that is a guided portion of the opening / closing body 41 when the opening / closing body 41 moves. The outer diameter of the roller 53 is substantially the same as the distance between the guide surfaces 12 of the guide recess 11.

  The connecting means 43 includes, for example, a plurality of (for example, four) connecting arms 55 made of a long plate material and a plurality of (for example, two) connecting short arms 65 made of a long plate material and slightly shorter than the connecting arms 55. Configured. That is, the plurality of opening / closing plates 42 are connected by the arms 55 and 65 like a pantograph. The arms 55 and 65 are connected to the outer surfaces of the left and right end portions of the opening / closing plate 42 in order to avoid contact with the opening / closing plate 42 when the opening / closing plate 42 rotates.

  As is clear from FIG. 10 and the like, the central portion in the longitudinal direction, which is the middle portion in the longitudinal direction of the connecting arm 55, is connected to the central portion in the plate surface direction, which is the middle portion in the plate surface direction of the one opening / closing plate 42, via the shaft 66. One end of the connecting arm 55 in the longitudinal direction of the connecting arm 55 is pivotally attached to one end in the plate surface direction of the other opening / closing plate 42 adjacent to the opening / closing plate 42 in the closing direction. The other end of the connecting arm 55 in the longitudinal direction is connected to the opening direction side of the one opening / closing plate 42, and the other opening / closing plate 42 has a plate surface direction, etc. It is rotatably attached to the end portion via a shaft 67.

  In addition, one end (lower end) in the longitudinal direction of the lower connecting short arm 65 is rotatably attached to the center in the plate surface direction, which is the middle portion in the plate surface direction of the lower opening / closing plate 42, via a shaft 66. The other end (upper end) in the longitudinal direction of the lower connecting short arm 65 is connected to the other end in the plate surface direction of the opening / closing plate 42 located adjacent to the opening direction side of the opening / closing plate 42 at the lower end via the shaft 67. It is pivotally attached.

  Further, the other longitudinal end portion (upper end portion) of the upper connecting short arm 65 is rotatably attached to the center portion in the plate surface direction which is the middle portion in the plate surface direction of the upper opening / closing plate 42 via the shaft 66, One end (lower end) in the longitudinal direction of the connecting short arm 65 on the upper end is rotated via a shaft 60 to one end in the plate surface direction of the opening / closing plate 42 positioned adjacent to the closing direction side of the opening / closing plate 42 at the upper end. It is mounted movably.

  A shaft 66 positioned at the center of the opening / closing plate 42 and a shaft 67 positioned at the other end of the opening / closing plate 42 in the plate surface direction are shafts 58, 60 positioned at one end of the opening / closing plate 42 in the plate surface direction. In the same manner, for example, the shaft portion of the truss machine screw 70 is configured. That is, the arm mounting portion located at the side end of the opening / closing plate 42 is connected to the mounting portion of the arms 55, 65 via the truss machine screw (mounting tool) 70, the spacer collar 71, and the washer 72. , 67 so as to be pivotable.

  Note that an operating means such as a remote control unit (not shown) is electrically connected to the electric motor 20 that moves the opening / closing body 41 in the opening / closing direction. The operation means includes, for example, an opening operation unit, a closing operation unit, and a stop operation unit.

  As shown in FIG. 4, a step 75 is formed on the upper front side of the lower case body 7, and when the opening 3 is fully closed, the bent portion 42a at the lower end of the lower opening / closing plate 42 is the step. Located in 75. Similarly, a step 42b is formed at the upper end of the opening / closing plate 42, and when the opening 3 is fully closed, a bent portion 42a at the lower end of the adjacent upper opening / closing plate 42 is located in the step 42b.

  Next, the operation and the like of the opening / closing device 1 will be described.

  For example, when the closing operation portion of the operating means is operated, the electric motor 20 is activated, the left and right endless bodies 31 are simultaneously rotated in the b direction, and the opening / closing body 41 is closed in the closing direction based on the rotation of both the endless bodies 31. To the predetermined fully closed position to close the opening 3 (fully closed). When the opening / closing body 41 is moved in the closing direction, the plurality of opening / closing plates 42 are simultaneously lowered so that the front end side (front end side) is lowered around the shafts 58 and 60 on the rear end side (base end side). Rotate.

  As shown in FIGS. 7A and 8, when the opening 3 is fully closed, the plurality of opening / closing plates 42 are in a fully closed posture that is a vertical posture along the up / down direction that is the opening / closing direction. , Located on the same plane along the vertical direction in a state of being close to each other. That is, the opening / closing body 41 is in a fully closed state of a flat plate shape (including a substantially flat plate shape) and closes the opening 3.

  Since each open / close plate 42 is formed in a flat plate shape (including a substantially flat plate shape), the open / close body 41 is in a flat plate-like fully closed state and closes the opening 3. However, if each open / close plate 42 and its surface are, for example, uneven, the open / close body 41 does not become a flat full-closed state but assumes a full-closed posture which is a vertical posture. Note that the fully closed posture is because the vertical length of each of the stacked open / close plates 42 is configured to be substantially equal to the height of the opening 3, and there is a gap at the lower end when fully closed. The total length and the height of the opening 3 do not necessarily have to be equal if they do not have to be vertical.

  Further, for example, when the opening operation portion of the operating means is operated, the electric motor 20 is activated, the left and right endless bodies 31 are simultaneously rotated in the a direction, and the opening / closing body 41 is moved based on the rotation of the both endless bodies 31. The opening 3 is opened (fully opened) by moving to a predetermined fully opened position in the opening direction. When the opening / closing body 41 moves in the opening direction, the plurality of opening / closing plates 42 rotate upward all at once so that the front end side rises around the rear end side shafts 58 and 60. That is, each open / close plate 42 rotates upward so as to protrude toward the outdoor side.

  As shown in FIGS. 7B and 9, when the opening 3 is fully opened, the plurality of opening and closing plates 42 are in a fully open posture that is a horizontal posture along a horizontal direction orthogonal to the opening and closing direction. Thus, they are positioned so as to be stacked in the vertical direction while being close to each other. That is, the opening / closing body 41 is in a rectangular parallelepiped full open state at a position near the lower side of the upper case body 6 to open the opening 3.

  During the movement and rotation of the opening / closing body 41, the roller 53 attached to the outer periphery of the shaft 60 provided at one end in the plate surface direction of the opening / closing plate 42, that is, near the indoor side end, Unlike the outdoor side end, which is the other end in the plate surface direction, one end portion in the plate surface direction of the opening / closing plate 42 does not protrude greatly to the indoor side and is substantially constant. Therefore, it does not protrude greatly behind the guide body (inside the room). For this reason, it is possible to arrange other opening / closing devices such as a sash window, for example, close to the indoor side of the opening / closing device 1.

  Furthermore, for example, when the operating unit for stopping the operating means is operated during the movement of the opening / closing body 41, the electric motor 20 stops and the opening / closing body 41 stops at an arbitrary position. As a result, for example, only a part on the closing direction side of the opening 3 as shown in FIGS. 7C and 10 is opened.

  When the opening 3 is partially opened, the plurality of opening and closing plates 42 are inclined with a desired inclination angle with respect to the up and down direction which is the opening and closing direction in a state where adjacent ones are spaced apart from each other in parallel. That is, it is located in a front-downward inclined shape that gradually descends toward the front end side. That is, the opening / closing body 41 has a stepped intermediate state and opens a part of the opening 3.

  In addition, when the opening 3 is partially opened, a ventilation gap 77 is formed between the inclined opening / closing plates 42 adjacent to each other. For this reason, even if the opening 3 is not fully opened, the plurality of air gaps 77 are provided, so that the air can be sufficiently passed through substantially the entire opening 3. The inclination angle of the opening / closing plate 42 can be set to an arbitrary angle within a range of 0 degrees to 90 degrees, for example. Although the present embodiment is configured to have the same inclination angle for all the opening / closing plates 42, the inclination angle may be adjusted for each opening / closing plate 42.

  Furthermore, when the opening 3 is partially opened, the front end side of the front-and-back inclined opening / closing plate 42 projects forward from the guide body 5 toward the front side. For this reason, the inclined opening / closing plate 42 can prevent, for example, sunlight (sunlight) from entering the room. That is, the opening / closing plate 42 also functions as an awning body that is an awning body.

  And according to such an opening / closing apparatus 1, compared with the structure etc. which wind up the opening / closing body which consists of shutter slats by the winding body in a storage body so that rewinding is possible, the structure can be simplified. Manufacturing costs can be reduced.

  In particular, the opening / closing plate 42 is larger and more rigid than the shutter slats of conventionally known shutter devices, so that the number of components constituting the opening / closing body 41 can be reduced, and the configuration can be simplified. Moreover, fluttering during strong winds can be prevented.

  In addition, the awning function and the ventilation function are realized by stopping the opening / closing body 41 at an arbitrary position during the opening / closing operation and inclining the plurality of opening / closing plates 42 so as to form a ventilation gap 77 between them. In addition, because of the simplicity of the configuration, it can be manufactured at a lower cost than a conventional shutter device having a sunshade function and a ventilation function. The sunshade function can be easily improved by increasing the length of the opening / closing plate 42 in the plate surface direction (length in the front-rear direction).

  Furthermore, since the movable body interlocking with the opening / closing body 41 is the endless body 31 that can be turned around the rotary bodies 17 and 27, it is possible to effectively simplify the configuration.

  Further, since the forward path portion 32 of the endless body 31 is disposed in the guide concave portion 11 of the guide body 5, the forward path portion 32 of the endless body 31 can be covered and protected by the guide concave portion 11, and the return path of the endless body 31 can be protected. Since the portion 33 is disposed in the front cylindrical portion 13 of the guide body 5, the return path portion 33 of the endless body 31 can be covered and protected by the front cylindrical portion 13.

  Next, FIG. 11 shows an opening / closing device 1 according to another embodiment.

  In order to improve the appearance from the indoor side, the opening / closing device 1 is attached to each guide body 5 and has a plate-like shape in the vertical direction that covers the gap between the side end of the opening / closing body 41 and the guide body 5. A gap cover body (decorative material) 80, which is a blindfolded body, and a plate-like opening / closing plate cover body which is attached to each opening / closing plate 42 and covers the entire indoor side surface (rear surface) of the opening / closing plate 42 in the left-right direction. Cosmetic material) 85.

  The gap cover body 80 is integrally formed of, for example, a plate material bent at a right angle at two locations. That is, the gap cover body 80 includes a first plate portion 81 fixedly attached to the rear cylindrical portion 14 of the guide body 5 and an inner side on the opening 3 side from the front end portion of the first plate portion 81. The second plate portion 82 projects toward the front, and the third plate portion 83 projects forward from the inner end portion of the second plate portion 82.

  The opening / closing plate cover body 85 has substantially the same size as the opening / closing member 61, and the entire indoor side surface (rear surface) of the opening / closing plate cover body 85 is formed in a flat and flat shape without any irregularities. In addition, the other structure of this switchgear 1 is the same as the structure of the said one Embodiment.

  In any of the above-described embodiments, the configuration in which the opening / closing body 41 is movable in the vertical direction and the opening / closing direction is the vertical direction has been described. However, for example, the opening / closing device 1 is placed horizontally and the opening / closing body 41 is in the horizontal direction. It is also possible to adopt a configuration in which the opening and closing direction is the left-right direction.

  Further, for example, for the purpose of improving safety, an obstacle sensing means for stopping the opening / closing body 41 when the opening / closing body 41 comes into contact with the obstacle may be provided.

  Further, for example, the electric motor 20 may not be provided, and the opening / closing body 41 may be opened and closed by manual operation by human power.

  Further, the movable body is not limited to the endless body 31 such as a chain or a belt, and may be a linear body that can be rewound and wound, for example.

  Further, the number of the opening / closing plates 42 constituting the opening / closing body 41 is arbitrary, and is appropriately set according to the size of the opening 3.

  In the above embodiment, the opening / closing plate 42 is configured so that the other end portion in the plate surface direction rotates downward when moving in the closing direction. For example, between the opening / closing plates 42 adjacent to each other during the opening / closing. The opening / closing plate 42 may be configured such that the other end side in the plate surface direction is rotated upward when moving in the closing direction for the purpose of facilitating sunlight from the gap. In order to do this, for example, the portion corresponding to the opening / closing plate 42 shown in FIG. 10 is changed to the connecting arm 55 (or the connecting short arm 65), and the portion corresponding to the connecting arm 55 (or the connecting short arm 65) is changed. The opening / closing plate 42 may be changed. However, in order to avoid contact with the opening / closing plate 42 when the opening / closing plate 42 rotates, the connecting arm 55 (or the connecting short arm 65), which is the connecting means 43, is located outside the left and right ends of the opening / closing plate 42. It must be connected to the side.
