  By the way, the door disclosed by patent document 1 has the ventilation path formed between the panel and the edge member provided in the side surface of the opening part in which this panel is arrange | positioned. However, it is difficult to ensure a sufficient ventilation function with only the ventilation path, and in order to sufficiently ventilate the room, it is necessary to open the door and open the building opening. However, opening the door in this way makes it easier to see a wide area of the room through the building opening from the outside. For this reason, people who are reluctant to see private rooms such as living rooms and bedrooms may feel uncomfortable.

  Here, it is conceivable that the door is provided with a lighting function and a ventilation function by providing a louver in addition to the panel. However, in this case, it is difficult to make the door have a simple appearance, and the structure may be complicated. In addition, since it is necessary to provide both the panel and the louver on a door having a limited size, it is difficult to secure a sufficient amount of light extraction and a sufficient amount of ventilation while ensuring the design of the door.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a door that is not complicated in structure and has a sufficient lighting function and ventilation function while ensuring design.

The door of this invention is equipped with the door main body and the flat lighting panel which is vertically long and has translucency. It said door body, the vent opening of the longitudinal penetrating in the thickness direction is provided two side by side in the vertical direction. In each of the upper and lower ventilation openings, the daylighting panel is provided so as to be rotatable about a vertical axis between a closed position for closing the ventilation opening and an opening position for opening the ventilation opening. Before SL lighting panel, the arranged inside the vent opening Ru rotatably mounted on said longitudinal axis. A pivot axis of the daylighting panel is located at an intermediate portion in the width direction of the daylighting panel. A rotation restricting means for holding the daylighting panel in each of a closed state and an open state is provided at an upper edge portion or a lower edge portion of the ventilation opening portion .

Moreover, it is preferable that the said lighting panel protrudes in the front-back direction rather than the said door main body in the open state.
Moreover, it is preferable that the said lighting panel becomes substantially parallel with the width direction of the said door main body in a closed position.

  The door according to the present invention allows light to enter the room through the daylighting panel. Further, the user can ventilate the room through the ventilation opening by arranging the lighting panel in the open position, and can block the ventilation opening by arranging the lighting panel in the closed position. That is, the door according to the present invention has both a ventilation function and a lighting function by using a light-transmitting daylighting panel as a member for opening and closing the ventilation opening. For this reason, the external appearance can be simplified and the structure can be simplified while ensuring both the ventilation function and the daylighting function.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(First embodiment)
FIG. 2 is a front view of the door 1 of the present embodiment. The door 1 is an indoor door provided in the building, and is used as a fitting that partitions the interior of the building in order to open and close the entrance of the room. Specifically, the door 1 is a hinged door that is pivotally provided in a building opening constituted by a door frame (not shown). In the following, the thickness direction of the door 1 will be described as the front-rear direction and the width direction as the left-right direction.

  The door 1 is formed with a ventilation opening 20 whose opening direction is the front-rear direction. A ventilation device 4 is provided in the ventilation opening 20. Specifically, the door 1 includes a door body 2. On the door side of the door body 2, two vertically long ventilation openings 20 are formed side by side so as to extend over substantially the entire length of the door body 2 in the vertical direction. Each ventilation opening 20 is provided with a ventilation device 4.

  Each ventilation device 4 includes a lighting panel 3 and a bearing unit 9 (see FIG. 4). The lighting panel 3 of each ventilation device 4 is vertically long and is provided in the ventilation opening 20. Each daylighting panel 3 is provided so as to be rotatable with respect to the door body 2 so that the corresponding ventilation opening 20 can be opened and closed. By selectively opening one of the upper and lower daylighting panels 3, ventilation can be performed while ensuring privateness.

  Each daylighting panel 3 is rotatable about the vertical axis on the door body 2 so that it can be rotated in the range from the closed position shown in FIG. 1 (a) to the open position shown in FIG. 1 (b). It is attached. Here, “around the vertical axis” means that the rotation axis direction of the daylighting panel 3 is parallel to the vertical direction (vertical direction). In the following description, unless otherwise specified, as illustrated in FIG. 1A, the description will be given with reference to the direction when the daylighting panel 3 is disposed at the closed position where the ventilation opening 20 is closed. . That is, description will be made assuming that the thickness direction of the daylighting panel 3 is the front-rear direction and the width direction of the daylighting panel 3 is the left-right direction.

  The vertical length of each daylighting panel 3 is substantially the same as the vertical length of the corresponding ventilation opening 20. The thickness of each daylighting panel 3 is smaller than the thickness of the door body 2. The width of each daylighting panel 3 is slightly smaller than the width of the corresponding ventilation opening 20.

  As shown in FIG. 5, each daylighting panel 3 is composed of a light-transmitting vertically long flat plate-shaped light transmitting plate 30 and a panel frame 5 that surrounds and holds the four circumferences of the light transmitting plate 30. The translucent plate 30 having translucency is not limited to a transparent one, but includes a translucent or opaque one such as frosted glass.

  The translucent plate 30 of each daylighting panel 3 is made of a glass plate. Specifically, the translucent plate 30 is a laminated glass in which two plate glasses are bonded via a synthetic resin film. Laminated glass has low chargeability. For this reason, it is difficult for the daylighting panel 3 to be covered with dust and dirt.

  The translucent plate 30 of each daylighting panel 3 is formed in a vertically long rectangular shape. Moreover, the translucent plate 30 of each daylighting panel 3 is formed in a rectangular shape whose horizontal cross-sectional shape is long horizontally as shown in FIG.

  As shown in FIG. 5, the panel frame 5 of each daylighting panel 3 includes left and right vertical frame members 50 and upper and lower horizontal frame members 51. The left and right vertical frame members 50 and the upper and lower horizontal frame members 51 are framed in a vertically long rectangular shape.

  Each vertical frame member 50 constitutes a side edge portion of the daylighting panel 3. Each vertical frame member 50 is made of metal, for example, aluminum. The length of each vertically long vertical frame member 50 is substantially the same as the length of the translucent plate 30.

  The horizontal cross-sectional shape of each vertical frame member 50 is uniform over the vertical direction. As shown in FIG. 1A, each vertical frame member 50 is formed in a groove shape (substantially C-shaped) whose horizontal cross-sectional shape is open to the light-transmitting plate 30 side. Each of the vertical frame members 50 includes a main part 500 that forms the groove back part, and an edge part 501 that protrudes from the front and rear end parts of the main part 500 toward the translucent plate 30.

  On the inner side surface, which is the surface on the other vertical frame member 50 side, of each vertical frame member 50, a vertical groove portion 502 opened on the other vertical frame member 50 side is formed in the vertical direction. The vertical groove portion 502 of each vertical frame member 50 is configured such that the depth of the groove is the surface of the main portion 500 on the other vertical frame member 50 side, and the side surface of the groove is the opposite surface of both edge portions 501. Each vertical frame member 50 is fitted to the translucent plate 30 by fitting the side end portion of the translucent plate 30 into the vertical groove portion 502.

  The thickness (front-rear dimension) of the main portion 500 of each vertical frame member 50 decreases as the distance from the translucent plate 30 side increases. The front surface portion and the rear surface portion, which are the surface portions of the main portion 500, are inclined surface portions 503 that are inclined so as to approach each other as the distance from the translucent plate 30 side increases. The surface portions 504 of the front and rear edge portions 501 of each vertical frame member 50 are orthogonal to the groove width direction (front-rear direction) of the vertical groove portion 502.

  In a state where each vertical frame member 50 is fitted to the translucent plate 30, the surface portions 504 of the front and rear edge portions 501 of each vertical frame member 50 are parallel to both front and rear surfaces of the translucent plate 30. Each daylighting panel 3 is inclined with respect to the width direction of the door body 2 when arranged in the open position shown in FIG. At this time, the inclined surface portion 503 on the front side of the vertical frame member 50 on the door end side is parallel and flush with the front surface of the door body 2. In addition, the inclined surface portion 503 on the rear side of the vertical frame member 50 on the suspending side is parallel and flush with the rear surface of the door body 2.

  Screw screwed portions are formed at the upper and lower ends of each vertical frame member 50. In the present embodiment, a screw pocket 505 having a C-shaped horizontal cross section is formed in the vertical direction on the groove rear surface of the vertical groove portion 502. The screw screw-in part is constituted by the upper and lower end parts of the screw pocket 505.

  As shown in FIG. 5, the horizontally long horizontal frame member 51 is bridged between the upper end portions and the lower end portions of both vertical frame members 50. Screw holes (not shown) penetrating vertically are formed at both ends in the length direction of each horizontal frame member 51. Each horizontal frame member 51 is formed with a horizontal groove portion (not shown) that opens to the side of the light transmitting plate 30 in the left-right direction.

  Each horizontal frame member 51 is fitted to the translucent plate 30 by fitting an end portion in the longitudinal direction of the translucent plate 30 into the horizontal groove portion. Screws 52 are passed through the screw holes of the horizontal frame members 51 from the side opposite to the translucent plate 30 in the vertical direction. These screws 52 are screwed into the screw screwed portions of the corresponding vertical frame members 50. Thereby, each horizontal frame member 51 is attached to both vertical frame members 50. That is, the translucent plate 30 has both left and right end portions fitted into the vertical groove portion 502 of the panel frame 5, and upper and lower end portions are fitted into the horizontal groove portion of the panel frame 5. The translucent plate 30 is held by the panel frame 5 by being sandwiched between the left and right vertical frame members 50 and the upper and lower horizontal frame members 51.

  A shaft portion 510 is formed on the outer surface of the upper and lower horizontal frame members 51 on the opposite side to the translucent plate 30 in the longitudinal direction of the horizontal frame member 51 so as to protrude on the opposite side of the translucent plate 30. These shaft portions 510 constitute the rotation axis of the daylighting panel 3 with the axial center thereof coinciding with the center line passing through the center of the translucent plate 30 in the horizontal section. That is, these shaft portions 510 function as supported portions that are supported so as to be rotatable about the vertical axis with respect to the door body 2.

  Each of the daylighting panels 3 is attached to the door body 2 so as to be rotatable about the vertical axis by the upper and lower shaft portions 510 being rotatably supported by bearing portions provided above and below the ventilation opening 20. It has been.

  The door main body 2 is composed of left and right door members 6 and a connecting member 7 that connects the door members 6 as shown in FIG.

  Both door members 6 are formed in a vertically long rectangular plate shape. The door-side door material 6 constitutes the door-side end of the door body 2. The door-side door material 6 is wider than the door-side door material 6 and constitutes the majority (excluding the door-side portion) of the door body 2.

  As shown in FIG. 2, both the door members 6 are connected to each other at the upper end portion, the lower end portion, and the intermediate portion by a horizontally long connecting member 7. As a result, the door body 2 is formed with two vertically-long rectangular ventilation openings 20. Hereinafter, when particularly distinguishing, the upper connecting member 7, the lower connecting member 7, and the connecting member 7 therebetween are referred to as an upper connecting member 70, a lower connecting member 71, and an intermediate connecting member 72, respectively.

  The upper ventilation opening 20 is surrounded by the upper connecting member 70, the intermediate connecting member 72, and the upper portions of the left and right door members 6. The upper edge of the upper ventilation opening 20 is constituted by the upper connecting member 70, and the lower edge of the upper ventilation opening 20 is constituted by the intermediate connecting member 72. The left and right edges of the upper ventilation opening 20 are composed of left and right door members 6.

  The lower ventilation opening 20 is surrounded by the intermediate connecting member 72, the lower connecting member 71, and the lower portions of the left and right door members 6. An upper edge portion of the lower ventilation opening 20 is constituted by an intermediate connecting member 72, and a lower edge portion of the lower ventilation opening 20 is constituted by a lower connecting member 71. The left and right edges of the lower ventilation opening 20 are constituted by left and right door members 6.

  Both door members 6 are plate-like panel members having a so-called flash structure. That is, as shown in FIG. 1, both the door materials 6 are obtained by covering the surface of the core material 64 with the surface material 65. The core member 64 of each door member 6 is made of wood, and is constituted by a frame body having a rectangular shape in front view.

  The surface material 65 of each door material 6 includes a plate material 650 and a decorative sheet 651 laminated on the surface of the plate material 650. The decorative sheet 651 is made of synthetic resin and has a wood grain pattern on its surface. A bent groove is formed on the back surface of the plate member 650 of the surface member 65 of each door member 6. The surface member 65 of each door member 6 is provided along the outer peripheral surface of the core member 64 by being bent at the bending groove.

  As shown in FIG. 5, fitting groove portions 62 that open to the other door member 6 are formed on the upper and lower end surfaces of each door member 6. As shown in FIG. 3, the fitting groove 62 is a portion into which the upper connecting member 70 and the lower connecting member 71 are fitted.

  A vertically long groove 63 (see FIG. 1) is formed on the side surface of each door member 6 on the other door member 6 side. Each recessed groove part 63 is formed over the part except the upper and lower ends where the fitting groove part 62 of the door member 6 is formed. Each concave groove portion 63 is formed in an intermediate portion in the thickness direction of the door member 6.

  The intermediate connecting material 72 shown in FIG. 5 is formed of a solid material or a panel material similar to the door material 6. A plurality of dowels 720 are provided on both end surfaces of the intermediate connecting member 72. In the illustrated example, dowels 720 are provided above and below both side end surfaces of the intermediate coupling member 72.

  Both end portions of the intermediate connecting member 72 are fitted into a wide recess 630 formed in an intermediate portion of the concave groove portion 63 in the length direction. Each dowel 720 of the intermediate connecting member 72 is fitted into a dowel hole (not shown) formed in the back of the corresponding recess 630. Thereby, the intermediate portions in the vertical direction of both door members 6 are connected by the intermediate connecting member 72.

  As shown in FIG. 1A, the edge concealing material 8 is attached to both side surfaces of each ventilation opening 20. Each edge concealment member 8 extends over the entire length of the corresponding vent opening 20 in the vertical direction. Each edge masking material 8 is made of synthetic resin. A wood grain pattern is applied to the surface of each edge cover material 8. In addition, each edge concealment material 8 is not restricted to the product made from a synthetic resin, For example, wooden may be sufficient.

  The horizontal cross-sectional shape of each edge masking material 8 is uniform over the vertical direction. Each edge concealment member 8 is attached to the door member 6 by fitting one end portion in the width direction into the concave groove portion 63 and bonding them.

  The thickness of each edge concealment material 8 is substantially the same as the thickness of the daylighting panel 3 (panel frame 5) and smaller than the thickness of the door body 2 (door material 6). Each edge concealment member 8 is accommodated within the thickness range of the door body 2. By doing so, it is possible to make the edge concealment material 8 small and to make the edge concealment material 8 difficult to obstruct the ventilation when the ventilation opening 20 is opened. The thickness of each edge concealment material 8 is preferably ½ or less of the thickness of the door body 2 in order to ensure a sufficient amount of ventilation.

  The edge concealment material 8 on both sides of each ventilation opening 20 is located at an intermediate portion in the thickness direction of the door body 2 and faces each other.

  A portion of each edge concealing member 8 opposite to the recessed groove portion 63 protrudes from the side surface of the ventilation opening 20 toward the inside in the width direction of the ventilation opening 20. Each edge concealment member 8 is formed with a protrusion 80 that protrudes toward the daylighting panel 3.

  Of the edge masking material 8 on both sides of each ventilation opening 20, the protruding portion 80 of the door masking material 8 protrudes from the rear portion of the edge masking material 8 toward the daylighting panel 3. On the other hand, the protruding portion 80 of the edge hiding material 8 on the hanging side protrudes from the front portion of the edge hiding material 8 toward the daylighting panel 3 side.

  As shown in FIG. 1A, the daylighting panel 3 arranged at the closed position is parallel to the width direction of the door body 2 (the width direction of the door member 6). At this time, both the vertical frame members 50 overlap with the protruding end portions of the corresponding protruding portions 80 of the edge masking material 8 when viewed from the front-rear direction. Thereby, the clearance gap between the side surface by the side of the door tip of the ventilation opening part 20 and the lighting panel 3 is block | closed by the edge concealment material 8 by the door tip side. Further, the gap between the side surface of the ventilation opening 20 on the suspension side and the daylighting panel 3 is closed by the edge concealment member 8 on the suspension side. Therefore, in this case, substantially the entire ventilation opening 20 is closed by the daylighting panel 3, and the ventilation of the room by the ventilation opening 20 is not performed. Further, when the daylighting panel 3 is closed as described above, it is difficult to see the opposite side of the door 1 through the ventilation opening 20 when the door 1 is viewed from the front-rear direction.

  Of the edge masking material 8 on both sides of each ventilation opening 20, the front surface of the protrusion 80 of the door masking material 8 is an inclined surface 81 that is inclined so as to be located rearward as it goes to the suspension side. ing. Moreover, the rear surface of the protrusion 80 of the hiding material 8 on the suspending side is also an inclined surface 81 that is inclined so as to be located rearward as it goes to the suspending side. The inclined surface 81 of the door cover material 8 and the inclined surface 81 of the suspension material cover 8 are substantially parallel.

  As shown in FIG. 1A, when each daylighting panel 3 is disposed at the closed position, the inclined surface portion 503 on the rear side of the vertical frame member 50 on the doorside side of the daylighting panel 3 has an edge on the doorside side. It is substantially parallel to the inclined surface 81 of the hidden material 8 and is in surface contact with the inclined surface 81 so as to face it. In addition, the inclined surface portion 503 on the front side of the vertical frame member 50 on the hanging side is substantially parallel to the inclined surface 81 of the edge hiding material 8 on the hanging side, and is in surface contact with the inclined surface 81 so as to face the inclined surface 81. Therefore, when each daylighting panel 3 is disposed at the closed position, it is possible to improve the adhesion between the daylighting panel 3 and the edge concealing material 8 and to reliably block ventilation.

  As shown in FIG. 5, an insertion hole 721 is formed at the center of each of the upper surface and the lower surface of the intermediate connecting member 72. The upper daylighting panel 3 of the upper and lower daylighting panels 3 has a lower shaft portion 510 inserted into an insertion hole 721 formed in the upper surface of the intermediate connecting member 72 and is supported rotatably. Although not shown, the lower daylighting panel 3 is rotatably supported by inserting the upper shaft portion 510 into an insertion hole formed in the lower surface of the intermediate connecting member 72. That is, in the present embodiment, the bearing portion that receives the shaft portion 510 on the side of the intermediate connection member 72 of the daylighting panel 3 is configured by the peripheral portions of the upper and lower insertion holes 721 of the intermediate connection member 72.

  The upper connecting member 70 and the lower connecting member 71 are rod-shaped, and the outer surface of a frame member 73 that is long on the left and right is covered with a decorative sheet member 74 (curtain plate).

  The frame members 73 of the upper connecting member 70 and the lower connecting member 71 are made of metal. Specifically, each frame member 73 of the upper connecting member 70 and the lower connecting member 71 is an extruded shape member made of aluminum. Thus, the upper connection material 70 and the lower connection material 71 are provided with metal profiles, whereby the strength of the upper connection material 70 and the lower connection material 71 can be increased.

  Each of the frame members 73 of the upper connecting member 70 and the lower connecting member 71 is formed in a substantially rectangular frame shape in the vertical cross-sectional shape.

  Each decorative sheet material 74 of the upper connecting material 70 and the lower connecting material 71 is made of synthetic resin. The decorative sheet material 74 is attached to the front and rear surfaces of the upper connecting material 70 and the lower connecting material 71, respectively. On the surface of the decorative sheet material 74 of the upper connecting material 70 and the lower connecting material 71, a wood grain pattern is given. For this reason, the upper connecting member 70 and the lower connecting member 71 have a wood-tone appearance imitating the door member 6.

  Each of the frame members 73 of the upper connecting member 70 and the lower connecting member 71 includes the bearing unit 9 shown in FIG. 4 as an additional unit of the door 1. That is, the bearing unit 9 is provided at the opening edge of each ventilation opening 20.

  The upper shaft portion 510 of the upper daylighting panel 3 is rotatably supported by the bearing unit 9 provided in the upper connecting member 70. The lower shaft portion 510 of the lower daylighting panel 3 is rotatably supported by the bearing unit 9 provided in the lower connecting member 71.

  Both bearing units 9 are vertically symmetrical. 6 and 7 show the bearing unit 9 provided on the upper connecting member 70. FIG.

  Each bearing unit 9 includes a casing 90, an arm 93, a damper 94, an urging member 95 (elastic body), a pressing body 96, and a movable body 97. As shown in FIG. 6, the arm 93, the damper 94, the biasing member 95, the pressing body 96, and the movable body 97 are housed in the casing 90.

  A casing 90 that is an outer shell of the bearing unit 9 is formed in a rectangular box shape that is long on the left and right. The casing 90 of the upper bearing unit 9 is housed in the upper connecting member 70 with its length direction parallel to the length direction of the upper connecting member 70. The casing 90 of the lower bearing unit 9 is housed in the lower connecting member 71 with its length direction parallel to the length direction of the lower connecting member 71. That is, each bearing unit 9 is provided along the opening edge of the ventilation opening 20.

  The casing 90 includes a plate-like base 91 that forms a surface portion on the daylighting panel 3 side, and a cover 92 that covers the base 91 in a box shape that opens to the daylighting panel 3 side.

  As shown in FIG. 7, a substantially fan-shaped (substantially triangular) recess 911 is formed on the inner surface of the base 91. A part of the inner peripheral surface of the recess 911 constitutes a rotation restricting surface 912 whose horizontal cross-sectional shape is substantially V-shaped opened to the door end side. An insertion hole 910 that penetrates the base 91 up and down is formed at the end of the bottom of the recess 911 on the suspension side (the end on the corner of the substantially V-shaped rotation restricting surface 912).

  Although not shown, the upper shaft portion 510 of the upper daylighting panel 3 is inserted into the insertion hole 910 of the bearing unit 9 in the upper connecting member 70 through the lower surface portion of the upper connecting member 70, and the concave portion of the bearing unit 9. 911 protrudes. Thus, the shaft portion 510 is rotatably supported by the upper bearing unit 9.

  The lower shaft portion 510 of the lower daylighting panel 3 is inserted into the insertion hole 910 of the bearing unit 9 through the upper surface portion of the lower connecting member 71 and protrudes into the recess 911 of the bearing unit 9. Thus, the shaft portion 510 is rotatably supported by the lower bearing unit 9. That is, in this embodiment, the bearing part which receives the axial part 510 on the opposite side to the intermediate | middle connection material 72 of the lighting panel 3 is comprised by the peripheral part of the penetration hole 910 of each bearing unit 9. As shown in FIG.

  An arm 93 is disposed in the recess 911. A connecting hole 930 is formed at one end of the arm 93 in the length direction. A shaft portion 510 opposite to the intermediate connection member 72 of the daylighting panel 3 is inserted into the connection hole 930, and the shaft portion 510 is fixed to the arm 93. Thereby, the arm 93 is configured to rotate together with the shaft portion 510 of the daylighting panel 3.

  The rotation range of the arm 93 is restricted by the rotation restriction surface 912 of the recess 911. The daylighting panel 3 is regulated by the rotation regulating surface 912 so as to be within the thickness range of the door body 2. That is, in the present embodiment, the rotation restricting surface 912 of the bearing unit 9 constitutes a rotation restricting unit that restricts the rotation range of the daylighting panel 3.

  When each daylighting panel 3 is disposed at the closed position, the corresponding arm 93 of the bearing unit 9 abuts on the rear surface of the rotation restricting surface 912 as shown in FIG. It becomes impossible to rotate. The daylighting panel 3 arranged at the closed position in this way is arranged at the center of the door body 2 in the thickness direction as shown in FIG.

  When each daylighting panel 3 is arranged in the open position, the corresponding arm 93 of the bearing unit 9 abuts on the front surface of the rotation restricting surface 912 as shown in FIG. 8C and rotates to the front side. It becomes impossible. As shown in FIG. 1B, the daylighting panel 3 arranged in the open position in this way has one inclined surface portion positioned on the front side among the inclined surface portions 503 positioned at both ends in the thickness direction of the door body 2. 503 is disposed at the same position in the front-rear direction as the front surface of the door body 2. The other inclined surface portion 503 located on the rear side is disposed at the same position in the front-rear direction as the rear surface of the door body 2. The daylighting panel 3 arranged at the open position is accommodated within the thickness range of the door body 2.

  As shown in FIG. 7, an interlocking portion 931 that protrudes on the opposite side of the lighting panel 3 in the vertical direction is provided at the end of the arm 93 of each bearing unit 9 on the side opposite to the connection hole 930. The interlocking portion 931 of each bearing unit 9 is arranged at a position shifted to the door end side from the rotation center of the daylighting panel 3. The interlocking portion 931 of each bearing unit 9 is formed in a cylindrical shape whose axial direction is parallel to the vertical direction. The interlocking portion 931 of each bearing unit 9 has an outer peripheral surface with a circular horizontal cross section.

  The interlocking portion 931 of each bearing unit 9 rotates about the vertical axis together with the arm 93 around the shaft portion 510 when the corresponding lighting panel 3 rotates about the vertical axis. Specifically, the interlocking portion 931 of each bearing unit 9 moves to the front side when the lighting panel 3 rotates in the opening direction, and moves to the rear side when the lighting panel 3 rotates in the closing direction.

  The biasing member 95 of each bearing unit 9 is disposed on the door end side of the interlocking portion 931 as shown in FIG. The biasing member 95 of each bearing unit 9 is constituted by a coil spring that is long in the left-right direction (that is, the direction along the opening edge of the ventilation opening 20) and whose expansion / contraction direction is parallel to the left-right direction.

  A pressing body 96 is attached to the suspension side end of the urging member 95 of each bearing unit 9. The pressing body 96 of each bearing unit 9 is arranged side by side with the interlocking portion 931 in the left-right direction. The pressing body 96 of each bearing unit 9 is provided so as to be movable in the left-right direction. The biasing member 95 of each bearing unit 9 is supported by a cover 92 on the door end side. The urging member 95 of each bearing unit 9 constantly urges the pressing body 96 toward the suspending side (the interlocking portion 931 side) (gives elastic force).

  The surface of each bearing unit 9 facing the suspension base of the pressing body 96 constitutes a pressing surface 960 that presses the interlocking portion 931. The pressing surface 960 includes a first surface portion 961 and a second surface portion 962 positioned in front of the first surface portion 961. The first surface portion 961 is inclined so as to be positioned closer to the door tip side. The second surface portion 962 is inclined so as to be positioned closer to the door front side.

  The pressing surface 960 further includes an intermediate surface portion 963. The intermediate surface portion 963 is formed in an arc shape in which the horizontal cross-sectional shape is convex toward the hanging base side. The intermediate surface portion 963 has the first surface portion 961 and the second surface portion 962 continuous. The first surface portion 961 is longer in the front-rear direction than the second surface portion 962. The intermediate surface portion 963 is formed at a position closer to the front on the pressing surface 960 configured by the first surface portion 961, the second surface portion 962, and the intermediate surface portion 963.

  In the state where each daylighting panel 3 is disposed at the closed position, as shown in FIG. 8A, the interlocking portion 931 of the arm 93 of the corresponding bearing unit 9 comes into contact with the rear end portion of the first surface portion 961. Placed in position. The interlocking portion 931 is pressed rearward by the first surface portion 961 of the pressing body 96 biased by the biasing member 95. For this reason, the arm 93 is pressed against the rear surface of the rotation restricting surface 912, and the daylighting panel 3 is held in the closed position.

  When the user rotates the daylighting panel 3 disposed at the closed position in the opening direction (counterclockwise in the plan view), the arm 93 rotates about the shaft portion 510 to the front side. Along with this, the interlocking portion 931 moves forward while pushing the pressing body 96 against the biasing force of the biasing member 95 toward the door end, and gets over the intermediate surface portion 963 of the pressing body 96. Then, when the daylighting panel 3 is disposed at the open position, the interlocking portion 931 is disposed at a position where it contacts the second surface portion 962 as shown in FIG. Thus, in the state where the daylighting panel 3 is disposed at the open position, the interlocking portion 931 is pressed forward by the second surface portion 962 of the pressing body 96 urged toward the suspension side by the urging member 95. For this reason, the arm 93 is pressed against the front surface of the rotation restricting surface 912, and the daylighting panel 3 is held in the open position.

  When the user rotates the daylighting panel 3 arranged at the open position in the closing direction (clockwise in plan view), the arm 93 rotates rearward about the shaft portion 510. Accordingly, the interlocking portion 931 moves to the rear side while pushing the pressing body 96 against the urging force of the urging member 95 toward the door end side, and gets over the intermediate surface portion 963 of the pressing body 96. Then, when the daylighting panel 3 is closed to the predetermined opening angle, the interlocking portion 931 reaches a position where it contacts the front end portion of the first surface portion 961. When the interlocking portion 931 comes into contact with the front end portion of the first surface portion 961 in this way, the interlocking portion 931 is moved rearward by the first surface portion 961 of the pressing body 96 biased toward the suspension side by the biasing member 95. Pushed and moved, the arm 93 rotates rearward about the shaft portion 510. The rotation of the arm 93 by the biasing member 95 is performed until the interlocking portion 931 reaches the rear end portion of the first surface portion 961 and the arm 93 contacts the rear surface of the rotation restricting surface 912, that is, the daylighting panel. This is done until 3 is placed in the closed position. That is, the daylighting panel 3 closed to a predetermined opening angle is automatically rotated to the closed position by the urging force of the urging member 95.

  Here, the pressing body 96 and the arm 93 provided with the interlocking portion 931 are arranged so that the direction of the urging force parallel to the width direction of the door body 2 of the urging member 95 includes a component in the rotation direction of the daylighting panel 3. Then, an urging force transmitting means for transmitting the urging force of the urging member 95 to the daylighting panel 3 is configured. Therefore, when a coil spring or the like that is long in the width direction of the door body 2 is used as the urging member 95 as in this embodiment, the urging member 95 is within the range of the thickness of the door body 2 (connecting material 7). There is an advantage that it is easy to pay.

  The damper 94 of each bearing unit 9 is disposed on the suspension side of the interlocking portion 931. The damper 94 of each bearing unit 9 is a telescopic cylinder damper. Specifically, the damper 94 of each bearing unit 9 applies a damping force when the piston 940 moves in the direction in which the piston 940 is pushed into the cylinder 941, and automatically returns to the origin where the piston 940 is extended. There is a one-way oil damper equipped with.

  The damper 94 of each bearing unit 9 is disposed with the piston 940 facing the door end side. A movable body 97 is attached to the tip of the piston 940 of each bearing unit 9. The movable body 97 of each bearing unit 9 is arranged side by side with the interlocking portion 931 in the left-right direction. The surface on the door end side of the movable body 97 of each bearing unit 9 is a contact surface 970 with which the interlocking portion 931 contacts. The contact surface 970 is inclined so as to be positioned closer to the suspender side toward the front.

  In the state where the daylighting panel 3 is disposed at the open position, the damper 94 extends and the interlocking portion 931 is disposed on the front side of the contact surface 970 of the movable body 97 as shown in FIG. When the user rotates the daylighting panel 3 arranged at the open position to the closed position, the interlocking portion 931 pushes the movable body 97 toward the suspension side as the arm 93 rotates, and the contact surface 970 is moved. Move to the back. At this time, a damping force acts on the piston 940 that moves to the suspension side together with the movable body 97. Thereby, the rotating operation of the lighting panel 3 in the closing direction is buffered by the damper 94. Therefore, it is possible to prevent the daylighting panel 3 from being closed vigorously and generating a loud sound, and the daylighting panel 3 and the member receiving it can be prevented from being deformed or damaged. Further, when the daylighting panel 3 is closed, it is possible to prevent a finger or the like from being strongly sandwiched between the daylighting panel 3 and the side surface of the ventilation opening 20.

  When the user rotates the daylighting panel 3 to the open position, the interlocking unit 931 moves forward as the arm 93 rotates. At this time, the movable body 97 is moved by the return force of the damper 94. Following 931, it moves to the door end side, and it will be in the state shown in Drawing 8 (c).

  Here, the arm 93 provided with the interlocking portion 931 and the movable body 97 constitute an operation conversion means for converting the rotation operation of the daylighting panel 3 into an operation parallel to the width direction of the door body 2 of the piston 940. Yes. For this reason, there is an advantage that it is easy to fit the damper 94 within the range of the thickness of the door body 2 (connecting material 7) by using a cylinder damper long in the width direction of the door body 2 as the damper 94 as in the present embodiment. is there.

  As shown in FIG. 3, the left and right ends of the upper connecting member 70 and the lower connecting member 71 of the door body 2 are fitted into the fitting groove portions 62 of the corresponding door member 6 and screwed. The surface of the upper connecting member 70 opposite to the daylighting panel 3 is substantially flush with the upper surfaces of the door members 6 on both sides. The surface of the lower connecting member 71 opposite to the daylighting panel 3 is substantially flush with the lower surfaces of the door members 6 on both sides.

  As shown in FIG. 2, a lever handle 10 (lever type door knob) is attached to both front and rear surfaces of the door material 6 on the door tip side as a handle. Each lever handle 10 is disposed at the same position as the intermediate coupling member 72 that becomes the boundary between the two ventilation openings 20 in the vertical direction of the door body 2.

  Each lever handle 10 includes a lever portion 100. The lever portion 100 of each lever handle 10 is rotatable in a range from a non-rotating position (non-use position) to a rotating position. Each lever handle 10 is configured to operate a latch (not shown) provided in the door body 2 when the door 1 is opened by rotating the lever portion 100 to the rotation position. Moreover, the lever part 100 of each lever handle 10 is automatically returned from a rotation position to a non-rotation position by an urging member constituted by, for example, a spring or the like.

  When the lever portion 100 of each lever handle 10 is disposed at the non-rotating position, the lever portion 100 protrudes toward the suspension side and is parallel (horizontal) to the width direction of the door 1. At this time, the tip portion of the lever portion 100 opposite to the rotation shaft is disposed at a position overlapping the intermediate connecting member 72 in the front-rear direction. For this reason, when the door 1 is viewed from the front, the intermediate coupling member 72 is located on the rear side of the front portion of the lever portion 100. Therefore, the daylighting panel 3 is not easily hidden by the lever portion 100 of the lever handle 10, and a sufficient amount of light can be taken from the daylighting panel 3.

  The door 1 of this embodiment described above includes a door body 2 and a lighting panel 3 that is vertically long and has translucency. The door main body 2 is provided with a vertically long ventilation opening 20 penetrating in the thickness direction. The lighting panel 3 is provided in the ventilation opening 20 so as to be rotatable about the vertical axis between a closed position where the ventilation opening 20 is closed and an open position where the ventilation opening 20 is opened.

  The door 1 can take light into the room through the daylighting panel 3. Further, the user can ventilate the room through the ventilation opening 20 by arranging the lighting panel 3 in the open position, and can block the ventilation opening 20 by arranging the lighting panel 3 in the closed position. That is, the door 1 of this embodiment can have both a ventilation function and a lighting function by using the light-transmitting daylighting panel 3 as a member for opening and closing the ventilation opening 20. For this reason, the external appearance of the door 1 can be simplified while ensuring both the ventilation function and the daylighting function, and the structure of the door 1 can be simplified.

  Further, by providing the daylighting panel 3 so as to be rotatable about the vertical axis, the area of the surface facing the upper side of the daylighting panel 3 is reduced as compared with the case where it is provided so as to be rotatable about the horizontal axis. The panel 3 is less likely to get dust or dirt. Further, when the light is taken into the room through the daylighting panel 3, dust or dust accumulated on the daylighting panel 3 is not easily reflected in the shadow. Further, by making the daylighting panel 3 rotatable around the vertical axis vertically long, a ventilation space formed between the daylighting panel 3 arranged at the open position and both side surfaces of the ventilation opening 20 is enlarged. It is also possible to ensure a sufficient amount of ventilation.

  Further, as in the present embodiment, the side surface of the ventilation opening 20 protrudes toward the inner side in the width direction of the ventilation opening 20, and the protruding end portion is disposed at the closed position when viewed from the thickness direction of the door body 2. It is preferable that the edge concealment material 8 that overlaps the side edge of the daylighting panel 3 is attached. By doing in this way, when the lighting panel 3 is arrange | positioned in a closed position, between the lighting panel 3 and the side surface of the ventilation | gas_flowing opening part 20 is covered with the edge covering material 8, and it is hard to pass air in the ventilation | gas_flowing opening part 20. can do.

In this way, by placing the edge masking material 8 within the range of the thickness of the door body 2, the edge masking material 8 can be made inconspicuous, and the edge masking material 8 can be made smaller to reduce the material cost. You can also.

  Moreover, the edge masking material 8 is provided on both sides of the ventilation opening 20 as in the present embodiment, and the side wall of each edge masking material 8 on the daylighting panel 3 side is arranged from one end side to the other end side in the thickness direction of the door body 2. It is preferable that the inclined surface 81 located in the width direction one end side of the ventilation | gas_flowing opening part 20 is provided so that it goes to. By providing the inclined surface 81 on each edge concealing member 8 in this way, even when there is some assembly error or dimensional error, the daylighting panel 3 rotates between the closed position and the open position. It is possible to make it difficult to contact the edge masking material 8. Each edge concealment member 8 has a curved surface curved so as to be positioned at one end side in the width direction of the vent opening 20 as it goes from one end side to the other end side in the thickness direction of the door body 2 instead of the inclined surface 81. It may be provided.
