  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a sunroom. The sunroom A includes four pillars 1, a single-flow roof 2 disposed on the four pillars 1, and both sides. It is provided with a ventilation window 3 arranged at the upper side in the plane, a folding door 4 arranged at the lower side of the ventilation window 3, and a fitting killing part 5 arranged so as to close the front surface at the front. It is made of aluminum.

  The single-flow roof 2 is between the rafters 21 arranged on a pair of struts 1 erected along the wall of the building in the above four corners and the girders 22 arranged on the other pair of struts 1 erected on the garden side. The rafters 23 on both sides in the width direction and the rafters 26 are tilted forward and fixed in the middle of the rafters 23 to form a frame structure, and the roof between the rafters 23 and 26 and between the rafters 26. A panel 27 is placed and a rafter cover is placed and fixed on the wife rafter 23 and rafter 26, and the roof panel 27 is sandwiched and fixed so as to be inclined forward from the building wall to the garden side.

  The ventilation window 3 is provided with an inclined upper rod 31 that is inclined forward in accordance with the inclination angle of the wife rafter 23 on the single-flow roof 2, and a horizontal lower rod 33 that is connected to a girder 28 disposed below the wife rafter 23 by a hinge 35. It is formed into an irregular trapezoidal shape, and a pair of connecting arms 40 in the longitudinal direction is arranged between the above-mentioned wife rafter 23 and the inclined upper bar 31 and connected to each other, thereby restricting the maximum opening angle and allowing it to be closed by the lock device 60. In this case, in the sunroom A of this example, a screen door 36 is installed on the outdoor side between the wife rafter 23 and the wife beam 28, and the ventilation window 3 is an inwardly ventilating window that pivots open and close toward the indoor side, and the arrangement of the connecting arm 40 with respect to the wife rafter 23 is installed on the lower surface of the wife rafter 23 and tilted forward with the inclination angle matched with this For upper frame 24 There as been to indirectly.

  The modified trapezoidal ventilation window 3 of this example has a length of about 10 cm on the building side and about 50 cm on the garden side, short on the building side, and long on the garden side, at the ends of the above-mentioned inclined upper ridge 31 and horizontal lower ridge 33. The vertical ridges 34 are arranged and assembled, and a glass or resin panel is fitted into the reinforced assembly, for example, so that the width is set to about 2.5 m in accordance with the inclined roof.

  The pair of connecting arms 40 are pivotally connected to the shaft support holes of the pair of connecting arms 40 in the longitudinal direction. Supporting each end of the connecting arm 40 in a pivotal manner and spaced apart in the longitudinal direction of the inclined upper collar 31 on each slide guide 41 arranged from the intermediate position of the pair of connecting arms 40 in the longitudinal direction toward the other end side The pair of engaging shafts 32 in the longitudinal direction are slidably guided, while the engaging shaft 53 of the bracket 50 and the engaging shafts 32 of the inclined upper collar 31 are formed longer with stoppers at their upper ends. Then, the shaft support hole of the connection arm 40 is made larger in diameter than the longer engagement shafts 32 and 53 and the slide guide 41 of the connection arm 40 is widened, so that the engagement shaft 5 of the bracket 50 of the connection arm 40 is increased. By making the shaft support by the slide support and the slide guide 41 of the engagement shaft 32 swing up and down, the connecting arm 40 can follow the protrusion of the rotation of the tilted upper bar 31 and the lower part of the trumpet 23 In this way, in general, inwardly or outwardly facing windows, connecting arms are arranged between the vertical frame and vertical wall of the window frame, and the vertical wall 34 on the building wall side is particularly short. Therefore, the arrangement of the connecting arm 40 with respect to the vertical rod 34 is not appropriate, and the connecting arm 40 is arranged on the above-mentioned wife rafter 23, in this example, the inclined upper frame 24 and the inclined upper rod 31, for opening and closing. Even when the rotating upper tilting rod 31 is connected, the ventilation window 3 can be easily opened and closed smoothly.

  The connecting arm 40 is constituted by a metal plate having a shaft support hole at one end in the longitudinal direction, a slide guide 41 from the middle position in the longitudinal direction toward the other end, and a sliding slot in this example. The bracket 50 is, for example, a plate metal fitting having an inverted L-shaped cross section including an upright piece 51 and a support piece 52 provided with an engagement shaft 53. The upright piece 51 is used as the wife rafter 23 in this example. Are screwed to the vertical surface of the inclined upper frame 24 and are fixed at two positions in the middle in the longitudinal direction so that the engagement shaft 53 is located between the end rafter 23 and the inclined upper frame 24.

  The pair of connecting arms 40 receive and engage the engagement shaft 53 of the support piece 52 in the shaft support hole, thereby supporting one end in the longitudinal direction of the bracket 50 of the wife rafter 23 to support the wife rafter 23. In this example, it is arranged so as to protrude toward the indoor side by its rotation from the position.

  The engaging shaft 32 of the inclined upper rod 31 is, for example, in the middle in the longitudinal direction of the inclined upper rod 31 and is located on the center side from the pivotal support position of the above-mentioned end rafter 23, in this example, the connecting arm 40 of the inclined upper frame 24. When the ventilation arm 3 is opened when the pair of connection arms 40 are engaged with each other, the connection arm 40 is displaced from the inclined upper rod 31 when the pair of connection arms 40 are engaged. It is configured to expand toward the end of the wife rafter 23 so as to project in a C-shape.

  The engaging shaft 32 of the inclined upper collar 31 can be guided in the longitudinal direction of the connecting arm 40 by a slide guide 41 which is a slide long hole of the connecting arm 40. At this time, the connecting arm 40 has its longitudinal direction. One end in the direction is pivotally supported by the end rafter 23, in this example, the inclined upper frame 24, so that the engaging shaft 32 is guided in the longitudinal direction of the connecting arm 40 while the connecting arm 40 rotates. 32 reaches the end position in the middle of the slide guide 41 and the connecting arm 40 holds the engaging shaft 32 in a fixed position. As a result, the ventilation window 3 is held at its maximum opening angle, and the pair of connecting arms 40 are connected to the ventilation window. 3 is maintained so that it can be ventilated. In this example, the maximum opening angle of the ventilation window 3 is an angle for opening a relatively narrow angle of 30 degrees or less, for example, about 15 degrees, at which ventilation can be performed.

  The tilted upper collar 31 is pivoted around the position of the hinge 35 when opening and closing, with the distance between the position of the hinge 35 and the position of the engagement shaft 32 of the tilted upper collar 31 as the pivot radius. The guiding connecting arm 40 swings up and down so as to follow the rotation trajectory of the engaging shaft 32, that is, the upper end of the inclined upper rod 31, and to the indoor side as the ventilation window 3 is opened. With the above-mentioned C-shaped turning projection and the closing of the ventilation window 3, the wife rafter 23, in this example, between the inclined upper frame 24 and the inclined upper rod 31, parallel and overlapped with them. In this example, the swinging of the connecting arm 40 causes the pivotal support with the bracket riffle 23, that is, the bracket 50 installed on the inclined upper frame 24, as described above. Engagement shaft 53 having an upper end stopper that stands on bracket 50 is long. This is made possible by making the shaft support hole of the connecting arm 40 larger in diameter than the engagement shaft 53, and also makes the engagement shaft 32 of the inclined upper collar 31 that also has an upper end detent to be longer. In addition, this is made possible by making the slide guide 41 of the connecting arm 40 wider than the engaging shaft 32. At this time, the connecting arm 40 can have a length corresponding to the turning radius determined by the arrangement position of the engaging shaft 32. In this example, the connecting arm 40 has a large turning radius. This is used as a guide for the pair of engagement shafts 32 as a length matched to the engagement shaft 32 on the side, so that, in this example, the C-shaped rotation of the connecting arm 40 is performed. The dynamic protrusion is performed such that the larger the turning radius, the larger the spreading angle, and the smaller the turning angle, the smaller the spreading angle.

  In this example, the locking device 60 is biased upward by a spring 71 and penetrates the inclined upper collar 31 to have a locking portion 63 at the upper end and a hooking portion 66 at the lower end. A locking fitting 61 having an S-shaped cross section disposed on the inclined upper rod 31 so as to be swingable inward and outward, a sliding protrusion 69 that slides on the locking portion 63 of the locking fitting 61, and the sliding protrusion At the rear end in the depth direction of the piece 69, there is a locking hole 70 that elastically locks the locking portion 63 at the lower position of the wife rafter 23 by the urging force of the spring 71, and the wife rafter 23, In this example, it is formed with a plate-shaped metal fitting 67 arranged on the inclined upper frame 24. In this example, the arrangement of the metal fitting 67 with respect to the end rafter 23 is the same as that of the bracket 50. In addition, this is installed on the wife rafter 23, and the tilted upper frame 24 tilted forward in accordance with the tilt angle. There as been to indirectly for.

  The locking bracket 61 of this example is formed in the above-mentioned S-shape by the upper and lower vertical pieces 62, 65 and the connecting piece 64 that connects the vertical pieces 62, 65, and the upper end of the upper vertical piece 62 is the locking portion. 63, and the hook portion 66, which is a through hole in this example, is arranged in the lower vertical piece 65, and the locking metal fitting 61 is located on the upper and lower sides of the outdoor side at the intermediate position in the longitudinal direction of the inclined upper rod 31. The upper vertical piece 62 protrudes upward and downward from the inclined upper collar 31 in a notch hole having a lower width wide inward and outward, and the connecting piece 64 and the lower vertical piece 65 are disposed below the inclined upper collar 31. It is arranged so that it hangs downward from At this time, the upper end of the locking bracket 61 is fixed to the inclined upper rod 31 by fixing the upper end to this and fixing the lower end to the connecting piece 65 that passes through the inclined upper rod 31 and is positioned below it. The spring 71 is built in so as to urge the 62 toward the outdoor side, and the spring 71 swings the locking metal fitting 61 against the urging force, and the locking portion 63 is resiliently locked in the locking hole 70 of the metal fitting 67.

  In the present embodiment, the bracket 67 includes a fixed piece 68 screwed to the vertical surface of the inclined upper frame 24 and the sliding protrusion 69 inclined downward from the upper end of the fixed piece 68 in the same manner as the bracket 50. The locking portion 63 of the locking metal fitting 61 urged by the spring 71 in response to the closing movement of the ventilation window 3 slides the downwardly inclined sliding protrusion 69. The ventilation window 3 is locked by moving to the locking hole 70 and locking to the locking hole 70, while the biasing force of the spring 71 is pulled by pulling the hooking portion 63 of the locking metal fitting 61 downward. Against this, the locking part escapes downward from the locking hole 70 of the sliding protrusion 69 and the locking metal fitting 61 is swung in a rotating manner by pulling downward, and the locking part escapes from the locking hole 70. The part 63 slides the sliding protrusion 69 inward of the room and comes off from it. It is so as to release the lock of the ventilation window 3 by. At this time, the positional relationship between the locking portion 63 and the locking hole 70 is set according to the position where the connecting arm 40 is inserted into the lower part of the rafter 23, and the lock is automatically set by closing the ventilation window 3. It can be done.

  Therefore, by using an operating rod having a hook that can be hooked to the hook 66 at the tip, the ventilation window 3 is locked by pressing the upper portion of the ventilation window 3 with the operating rod, and the hook of the operating rod is hooked. The ventilation window 3 can be unlocked by hooking it on the portion 66 and pulling the locking fitting 61 downward. The operation rod can be opened and closed when a curtain is installed on the ceiling surface, for example. Since the operation rod used for the purpose is provided with a hook, it can be commonly used.

  The sun room A formed as described above ventilates the room by opening the ventilation window 3 and, as a result, can release hot air to the outside even in summer, and prevent hot air residue at night as much as possible. Discomfort in the building room can be eliminated as much as possible. In other words, the ventilation window 3 is formed by the sunroom A of the present example in which the front is set as the killing portion 5, the folding door 4 is arranged on the side, the ventilation window 3 is formed at the upper end of both sides, and the roof curtain is closed. When the discomfort index was measured on a clear day in the summer for both the opened and closed ventilation windows 3, the discomfort index increased from around 8 am when the discomfort index in the outdoor shade was zero. However, it increases about 30 to 50 from the outdoor at the peak, but when the peak is passed, the discomfort index decreases sharply in the former that opened the ventilation window 3, and it is about the same as the outdoor from around 5 pm On the other hand, in the latter case where the ventilation window 3 is closed, the discomfort index gradually decreases, and the discomfort index at around midnight is still about 10 higher than the outdoors. Depending on the arrangement and its use, during summer nights Kick it is possible to prevent the hot air remaining as much as possible to eliminate the discomfort of building the room as much as possible.

  Although the illustrated example is as described above, the connection arm is arranged with respect to the wife rafter by directly fixing the bracket to the wife rafter so as to be directly between the wife rafter and the upper slope.
