As shown in FIGS. 7 and 8 (a), this sash includes a frame 1 and a shoji 2 (upper shoji 2a and lower shoji 2b) that are connected vertically. The frame 1 is a frame in which a vertical frame 11 and a horizontal frame 12 are framed four times, and an invisible 13 is provided at the center in the vertical direction. Then, on the inner peripheral side of the frame body 1, the upper shoji 2 a is stored above the intangible 13, and the lower shoji 2 b is stored below the invisible 13.

  More specifically, as shown in FIG. 1 and FIG. 2, a bearing portion 21 having a substantially C-shaped cross section is formed at the left end portion of the upper shoji 2 a, and on the outdoor side portion on the inner peripheral side surface of the left vertical frame 11. The shaft member 22 extending from the upper end of the vertical frame 11 to the intangible 13 is screwed. The shaft member 22 has a shoji rotary shaft 23 at a position protruding to the inner peripheral side, and the bearing portion 21 of the upper shoji 2 a sandwiches the shoji rotary shaft 23, and the bearing portion 21 with respect to the shoji rotary shaft 23. Is freely rotatable. In this way, the upper shoji 2a is supported by the left vertical frame 11 on the left side, and can freely rotate around the vertical shoji rotating shaft 23, and can be opened and closed toward the outdoor side.

  And the stick 3 for performing opening / closing operation is attached to the upper shoji 2a. In addition, description about the protrusion stick | rod 3 of this paragraph is based on the fully open state of the upper shoji 2a shown in FIG.1 and FIG.3. The protruding rod 3 has an outdoor side portion 31, an intermediate portion 32, and an indoor side portion 33. The outdoor portion 31 is formed by joining two L-shaped metal fittings, and has a horizontal piece 311 oriented horizontally on the outdoor side and a vertical piece 312 oriented vertically on the indoor side. And the L-shaped attachment bracket 24 is attached to the door side part (right side expectation surface) of the upper shoji 2a, and the horizontal piece 311 of the outdoor side part 31 with respect to the attachment bracket 24 is the upper shoji 2a. The first rotating shaft 34 is mounted so as to be rotatable around a first rotating shaft 34 that is parallel to (i.e., perpendicular to) the rotating shaft. Further, the intermediate portion 32 is made of a bar having a rectangular cross section, and the outdoor end thereof is a second orthogonal to the vertical axis 312 of the outdoor portion 31 (that is, horizontal) perpendicular to the rotation axis of the upper shoji 2a. A rotating shaft 35 is rotatably attached. The total length of the outdoor portion 31 and the intermediate portion 32 is substantially the same as the left and right width of the upper shoji 2a. Further, the indoor side portion 33 is made of a bar having a rectangular cross section, and the outdoor side end portion thereof is parallel to (i.e., perpendicular to) the rotation axis of the upper shoji 2a with respect to the indoor side end portion of the intermediate portion 32. It is rotatably attached around the three rotation shafts 36. Further, at the indoor side end portion of the indoor side portion 33, a knob portion 37 is provided for picking with a finger when operating the protruding rod 3. An engagement recess 38 having a U-shaped cross section that opens downward is formed on the lower surface of the knob 37, and an engagement protrusion 39 that protrudes toward the indoor side is formed on the lower side of the indoor side of the knob 37. It is. Note that a click mechanism 7 is provided between the intermediate portion 32 and the indoor side portion 33 so as to be linear, and this will be described later.

  Further, a groove portion 111 having a U-shaped cross section and opening toward the indoor side is formed in the indoor side portion on the inner peripheral side surface of the left and right vertical frames 11. A guide hole 4 penetrating in the indoor / outdoor direction is provided on the bottom surface (finding surface) of the groove portion 111 of the right vertical frame 11 (that is, the side facing the side supporting the upper shoji 2a), and protrudes. The rod 3 passes through the guide hole 4. In addition, the receiver 5 is mounted in the groove 111 of the right vertical frame 11. As shown in FIGS. 1 to 4 and FIG. 8B, the receiving tool 5 is a box-shaped opening that opens to the indoor side, is contained within the expected width of the vertical frame 11, and the upper end portion is a guide hole. 4 and extends downward therefrom, and has a vertical length sufficient to accommodate the intermediate portion 32 and the indoor side portion 33 of the stick 3. A communication hole 51 that penetrates in the indoor and outdoor directions and communicates with the guide hole 4 is formed at a position of the bottom surface (finding surface) of the receiving member 5 that overlaps with the guide hole 4. The communication hole 51 is inserted together with the hole 4. Moreover, the upper end part (the part which the protrusion stick | rod 3 passes in a horizontal direction) of the inner surface of the right and left of the holder 5 is the inclined surface 52 so that it may spread toward the indoor side. Further, an engagement convex portion 53 that protrudes upward is formed at the indoor lower portion of the communication hole 51. Further, an extension piece 54 is provided on the lower surface of the receiver 5 so as to bend toward the upper side and extend toward the indoor side. An engagement protrusion 55 is formed. Note that U-shaped cover members 112 for closing the openings are inserted above and below the groove 5 of the left vertical frame 11 and the support 5 of the groove 111 of the right vertical frame 11. And as shown in FIG.1 and FIG.7, the fixed type | mold screen door 6 is attached to the indoor side edge part of the frame 1 (in the left-right vertical frame 11, the indoor side edge part of the inner peripheral side of the groove part 111). It is provided. The screen door 6 is a series of top and bottom, covering and covering the eyes 13 when viewed from the indoor side.

  As shown in FIGS. 1 and 3, the protruding bar 3 configured in this manner has the indoor side portion 33 substantially parallel to the indoor / outdoor direction in the fully open state of the upper shoji 2 a, and the intermediate portion 32 and the outdoor side portion 31. Is located on the outdoor side of the frame 1, and the intermediate part 32 is bent leftward (inner peripheral side direction) with respect to the indoor side part 33 (second between the outdoor side part 31 and the intermediate part 32). Since the rotating shaft 35 is horizontal, it does not bend here). At this time, the length of the portion of the protruding rod 3 that is located on the outer side of the frame 1, that is, the combined length of the outdoor side portion 31 and the intermediate portion 32 is substantially the same as the left and right width of the upper shoji 2a. As viewed, a substantially equilateral triangle is formed by the lateral frame 12 of the frame body 1, the upper shoji 2 a, and the outdoor portion 31 and the intermediate portion 32 of the stick 3. In the fully open state, by pushing down the knob 37, the engagement recess 38 on the lower surface of the knob 37 is engaged with the engagement protrusion 53 of the holder 5, and the stick 3 and the upper shoji 2a are fixed. Is done.

  Further, as shown in FIGS. 2 and 4, in the fully closed state of the upper shoji 2 a, the portion of the stick 3 located on the indoor side from the frame 1, that is, the intermediate portion 32 and the indoor side portion 33 are the outdoor side portion. It bends 90 degrees downward with respect to 31 and fits within the holder 5 along the vertical frame 11 (that is, the stick 3 is within the expected width of the vertical frame 11). Then, the engaging protrusion 39 of the knob 37 is engaged with the engaged protrusion 55 of the holder 5, and the protruding bar 3 is fixed. Therefore, the stick 3 functions as a locking mechanism for the upper shoji 2a.

  When the upper cover 2a configured as described above is released from the fully closed state, the knob 37 of the protruding rod 3 is put on the hand and pulled up indoors. At this time, the engaging protrusion 39 of the knob portion 37 is engaged with the engaged protrusion 55 of the holder 5, but by applying a certain amount of force, the extending piece 54 is elastically deformed and engaged. Canceled. When the intermediate portion 32 and the indoor side portion 33 are pulled up until they are horizontal, the stick 3 is pushed out toward the outdoor side. As a result, the upper shoji 2a opens to the outdoor side, and when the intermediate portion 32 passes through the guide hole 4, it begins to bend to the left with respect to the indoor side portion 33. And if it pushes in until the substantially full length of the indoor side part 33 is settled in the expected width of the frame 1, it will be in the fully open state shown in FIG.1 and FIG.3. Then, the knob | pick part 37 is pushed down, the engagement recessed part 38 is engaged with the engagement convex part 53 of the holder 5, and the upper shoji 2a is fixed in a fully open state. On the other hand, when closing from the fully open state, a hand is placed on the knob 37 of the protruding rod 3 and pushed up to release the engagement between the engagement recess 38 and the engagement protrusion 53 of the receiver 5. Pull on. Thereby, the upper shoji 2a is closed to the indoor side, and the inclination angle of the intermediate portion 32 with respect to the indoor side portion 33 is reduced. When the indoor side portion 33 and the intermediate portion 32 pass through the guide hole 4, the intermediate portion 32 is bent downward with respect to the outdoor side portion 31, and the intermediate portion 32 and the indoor side portion 33 are accommodated in the receiver 5. At the same time, the upper shoji 2a is drawn to the indoor side. At this time, the knob portion 37 is pushed toward the outdoor side, and the engaging protrusion 39 is engaged with the engaged protrusion 55 of the receiver 5 to fix the upper shoji 2a in the fully closed state. In addition, the part through which the protrusion rod 3 on the left and right inner surfaces of the receiver 5 passes is an inclined surface 52 so as to spread toward the indoor side, and is passing through the guide hole 4 and the communication hole 51 of the receiver 5. Since the protruding rod 3 can be tilted to approximately 10 degrees with respect to the indoor / outdoor direction, it is easier to push and pull.

  In the above description, the configuration and the operation of the upper shoji 2a have been described. However, the lower shoji 2b has the same configuration that is symmetrical with the upper shoji 2a as shown in FIGS. Therefore, the opening direction of the upper shoji 2a and the lower shoji 2b is alternate. As shown in FIG. 8 (a), the height of the stick 3 is located at the lower part of the upper shoji 2a, and at the upper part of the lower shoji 2b. 3 is close to the vertical center of the entire sash. In this manner, the two sticks 3 are arranged close to each other, so that it is easy to operate. Then, when both the upper shoji 2a and the lower shoji 2b are fully opened, the horizontal frame 12 of the frame 1 and the upper shoji 2a or the lower shoji 2b in each of the upper shoji 2a and the lower shoji 2b A substantially equilateral triangle is formed by the outdoor portion 31 and the intermediate portion 32 of the protruding rod 3. Then, as shown in FIG. 9, these are arranged vertically, the outdoor portion 31a and the intermediate portion 32a of the protruding rod 3a of the upper shoji 2a are positioned substantially directly above the lower shoji 2b, and the protruding rod of the lower shoji 2b The outdoor side portion 31b and the intermediate portion 32b of 3b are located substantially directly below the upper shoji 2a. Therefore, the entire sash is shaped like a regular triangular prism.

  A click mechanism 7 is provided between the intermediate portion 32 of the protruding rod 3 and the indoor side portion 33. The click mechanism 7 includes a concave curved surface 71 formed on the outdoor side end surface of the indoor side portion 33, a sphere 72, and a biasing member 73. The urging member 73 is formed of a coil spring, and is inserted into a hole 74 formed on the indoor side end surface of the intermediate portion 32. Further, a sphere 72 is inserted into the hole 74, and the urging member 73 is a sphere. 72 is pressed against the concave curved surface 71. By this click mechanism 7, since the sphere 72 is normally fitted into the concave curved surface 71, the indoor side portion 33 is fixed linearly with respect to the intermediate portion 32. Then, if a force is applied, the indoor side portion 33 can be inclined with respect to the intermediate portion 32, but if inclined, the concave curved surface 71 causes the spherical body 72 to resist the urging force of the urging member 73 and the intermediate portion 32. Therefore, the indoor side portion 33 is always urged in a direction to be linear with respect to the intermediate portion 32. The click mechanism 7 prevents the stick 3 from wobbling, so that it is easy to operate and does not collide with the frame 1 or the like.

  According to the sash thus configured, the protruding bar 3 is bent, so that the opening angle of the shoji 2 (the upper shoji 2a and the lower shoji 2b) is increased, and the indoor side portion 33 of the protruding bar 3 is directed indoors and outdoors. Since the guide hole 4 and the frame 1 can be found with small dimensions, the opening area of the window is increased and the design is slim. In addition, the indoor side portion 33 that is operated with a hand is operated only in a direction substantially parallel to the indoor / outdoor direction, so that the operability is good. Furthermore, since the stick 3 is inserted through the guide hole 4 provided in the groove 111 of the vertical frame 11, the stick 3 does not interfere with the screen door 6 provided on the inner peripheral side of the groove 111.

  In the fully closed state of the upper shoji 2a and the lower shoji 2b, the protruding rod 3 is bent along the vertical frame 11 and fits within the expected width of the vertical frame 11, and in the fully open state of the upper shoji 2a and the lower shoji 2b. Since most of the protruding rod 3 is positioned outside the frame 1, the protruding rod 3 and other members do not protrude indoors and pass in front of the window in any state. It will not be an obstacle. Moreover, since the upper shoji 2a and the lower shoji 2b are drawn close to the indoor side by the stick 3 and the other locking mechanism is not required. Further, since the protruding rod 3 is inserted through the guide hole 4 provided in the vertical frame 11 of the frame body 1, the visual dimension of the invisible 13 between the upper shoji 2 a and the lower shoji 2 b is reduced and Since there is no handle or the like that protrudes from the side 13 to the room side, a series of screen doors 6 in the vertical direction can be provided on the room side of the bed 13 to cover the bed 13 and make a clean design. Moreover, in the fully open state of the upper shoji 2a and the lower shoji 2b, the upper shoji 2a or the lower shoji 2b, the protruding bar 3, and the frame 1 form a substantially equilateral triangle in plan view, and these are arranged vertically. Since the sash is shaped like a regular triangular prism as a whole, the design is good. From the above, this sash has a smart appearance in both the fully open state and the fully closed state of the upper and lower shojis 2a and 2b, so that the design of the sash as a whole is good.

  The present invention is not limited to the above embodiment. For example, the shape of the shoji and the frame is an example, and any shape can be used as long as the shoji fits into the frame and opens to the outdoor side. Good. Furthermore, about a click mechanism, contrary to the said embodiment, a concave curved surface may be provided in an intermediate part, and a spherical body and a biasing member may be provided in an indoor side part.
