Description

  The present invention relates to an opening structure of an outer wall having a protruding window at an opening.

  In a building such as a house, it is preferable that a natural living wind is efficiently taken in from an opening to ventilate and ventilate so that a comfortable living environment can be obtained without relying on air conditioning equipment. Especially in mild weather seasons such as spring and autumn, opening the windows and ventilating them can provide a natural coolness and contribute to energy saving.

  On the other hand, in recent years, interest in crime prevention has increased, and ensuring the crime prevention performance of buildings has become an extremely important issue. In addition, it is required to secure high crime prevention performance in a single building and to form high-quality housing stock.

  In order to improve the crime prevention property at the opening, it is required to have a structure that is unlikely to be damaged by a burglar or the like and is not easily destroyed. It is also effective to make the opening difficult to be approached by an intruder or to make it feel difficult to approach. In particular, it is preferable to take a certain intrusion prevention measure for an opening that is relatively easy to approach from the outside, such as a window provided on the ground floor or a window facing an outdoor balcony.

  As an intrusion prevention measure for an opening that is not used for entering and exiting, for example, external attachment of a face grid or continuous connection of louvers or the like is widely performed. However, depending on the opening / closing method of the shoji, such as a single-opening window or a sliding window, there is a case where a face grid or a louver cannot be attached to the outdoor side. In addition, there is a concern that providing a louver or the like may cause a feeling of blockage in the living room or impair the aesthetics, and there is a problem that it is easy to visually recognize whether or not the shoji is opened.

  As a technique for providing crime prevention in a state where the shoji is opened, for example, in Patent Document 1, a lighting part and a wind part are connected in the window frame, and a transparent glass panel is fitted to the lighting part. A window having a structure in which a louver is fitted on the outdoor side is disclosed in the wind collecting section. In addition, it has been proposed that a parallel projecting shoji is provided on the indoor side of the wind sampling section, and the shoji is projected and opened on the indoor side of the gallery.

  The window of the conventional example still has a problem in practical use in a building such as a house. In other words, since it is a configuration in which a daylighting section for slaughtering and a windbreaking section equipped with a louver are arranged side by side, in addition to requiring a large wall surface at the place of installation, the parallel projecting shoji is opened to the indoor side and protrudes. Requires space for opening and closing inside. Therefore, it cannot be placed in any part of the building, and is not suitable for a narrow space such as a corridor, a staircase, or a watering room, and is inferior in design freedom. For efficient ventilation, the wind inlet and outlet should be planned in consideration of the wind flow of the entire building, but it is not possible to install windows that require such wide walls at multiple locations in the building. Often difficult. Moreover, since the shoji is pulled out to the indoor side, it is difficult to say that a clean appearance is formed on the indoor side.

  In this way, practical opening structures that have both ventilation and crime prevention, are easy to use, can form a good appearance design, and can be placed in any place are currently proposed. It wasn't. In addition, in order to create a comfortable living environment, ventilation and ventilation through the opening are important, but leaving the window open leaves unrest from the crime prevention aspect, and you have to close the window and rely on air conditioning equipment. There was a real situation.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to provide a comfortable living environment with good ventilation and lighting, and impair the appearance design. It is to realize an opening structure of the outer wall that can ensure high crime prevention performance without any problem and to contribute to the formation of high-quality housing stock.

  The solving means of the present invention for achieving the above object is premised on an opening structure of an outer wall in which a protruding window is internally attached to an opening provided in a wall body. With respect to this opening structure, as the projecting window, a frame member, a shoji that protrudes in parallel to the outdoor side with respect to the frame member, and the shoji that is provided between the frame member and the shoji are arranged in parallel. A moving link mechanism. The frame member is configured to retract and close the shoji near the indoor side of the opening. Further, the shoji is provided with a fixing means for restricting the protruding amount of the shoji, and when the shoji is fixed at an open position substantially flush with the outdoor surface of the wall, the shoji and the expected portion of the opening A gap is formed between the two.

  By this specific matter, it is possible to perform daylighting through the shoji, and it is possible to circulate and ventilate well by allowing the wind to circulate through the gap between the four sides of the shoji and the opening. Moreover, since the shoji is opened without protruding to the outdoor side of the wall body, it is difficult to recognize from the outside that it is open, and it can be formed as if it is fitted and killed. Therefore, it is possible to prevent the intruder from approaching, and even if it is approached, there is not enough space to insert a hand or tool around the shoji and it can be structured to be difficult to break or break. . Therefore, it can be set as the opening part structure excellent in all of ventilation property, daylighting property, design property, and crime prevention property.

  As a more specific configuration of the opening structure, at least a first opening position where the shoji is substantially flush with an outdoor surface of the wall body and a second opening position protruding from the outdoor surface of the wall body A configuration in which the protrusion amount in two stages can be selected is also possible.

  Thereby, at the time of normal ventilation or ventilation, the shoji can be protruded to the first open position to ensure both ventilation and crime prevention. In addition, when staying at home during the day or when it is desired to increase the ventilation, the shoji can be projected to the second open position for better ventilation. Thus, since the opening form of a shoji can be changed as needed, it is highly convenient and it is possible to arrange a comfortable living environment using natural wind.

  Furthermore, in the opening structure, it is preferable that the opening has a slit shape that is long in the height direction and narrow in the width direction.

  Thereby, the wind from the said opening part can be distribute | circulated evenly in the indoor height direction, and sufficient ventilation can be ensured, although it is space-saving. In addition, since the opening width of the protruding window is small, the size of the opening itself prevents intrusion of people, and it is difficult to be targeted as an intruder by the intruder, and the crime prevention performance is further improved. Is possible. In addition, with the opening having such a configuration, even if the shoji is broken, it can be prevented from entering the indoor side.

  Further, the present invention is premised on an opening structure of an outer wall in which a protruding window is attached to an opening provided in a wall, and the protruding window is opened to protrude parallel to the outdoor side with respect to the wall. As the shoji, when the shoji projecting width is fixed at an open position substantially flush with the outdoor surface of the wall body, the shoji and the expected portion of the opening It is good also as a structure which forms a clearance gap between them.

  By this specific matter, it is possible to perform daylighting through the shoji, and it is possible to circulate and ventilate well by allowing the wind to circulate through the gap between the four sides of the shoji and the opening. Moreover, since the shoji is opened without protruding to the outdoor side of the wall body, it is difficult to recognize from the outside that it is open, and it can be formed as if it is fitted and killed. Therefore, the approach of the intruder can be prevented, and even if it is approached, there is not enough space to insert a hand or a tool, and a structure that is not easily broken or broken can be obtained. Therefore, it can be set as the opening part structure excellent in all of ventilation property, daylighting property, design property, and crime prevention property.

  Moreover, in the said opening part structure, the said shoji is made into at least 2 steps | paragraphs of the 1st open position which is substantially flush with the outdoor surface of a wall body, and the 2nd open position which protrudes from the outdoor surface of a wall body. It is preferable that the protruding width is selectable.

  Thereby, at the time of normal ventilation or ventilation, the shoji can be protruded to the first open position to ensure both ventilation and crime prevention. In addition, when staying at home during the day or when it is desired to increase the ventilation, the shoji can be projected to the second open position for better ventilation. Thus, since the opening form of a shoji can be changed as needed, it is highly convenient and it is possible to arrange a comfortable living environment using natural wind.

  Furthermore, in the said opening part structure, it is good also as a structure which arranges the said opening part in parallel with the drawing-in side of the one-way entrance door arrange | positioned along the wall body at the outdoor side.

  This enables daylighting at the entrance and ensures ventilation even when the entrance door is closed. In addition, the shoji of the opening can be fixed to the outdoor side of the wall body so as to be substantially flush with the outdoor surface of the wall body, so that ventilation in a state of securing high crime prevention is possible. Is done. At this time, the opening does not interfere with the shoji when the entrance door is retracted, and makes it possible to open and close the entrance door safely and smoothly.

  In the present invention, lighting from the shoji at the opening and ventilation through the gap between the shoji and the opening are enabled. In addition, the shoji can be opened in a state that is substantially flush with the outdoor surface of the wall, so that it can be made less susceptible to intrusion damage and destruction, and high security performance without deteriorating the appearance design. Can be secured. Therefore, it can be set as the opening part structure which has both ventilation and crime prevention.

  As shown in FIGS. 1 and 2, in the outer wall opening structure according to the present embodiment, an opening 1 is provided in a wall body 11. The opening 1 has a slit shape (slot shape) that is long in the height direction and narrow in the width direction.

  In the illustrated embodiment, the opening 1 is formed in a vertically long and narrow shape having a height from the vicinity of the indoor floor surface 12 to the vicinity of the ceiling. As shown in FIG. 3, a ridge 13 is provided at the top of the opening 1, and a draining material 14 is provided at the bottom.

  As shown in FIG. 4, the outer wall material 15 constituting the wall body 11 is provided with an opening 151. On the indoor side surface of the outer wall member 15, a shaft assembly member 16 having an appropriate cross-sectional dimension is disposed along the outer peripheral portion of the opening 151. An attachment member 17 for the parallel projecting window 10 is attached to the shaft assembly member 16.

  On the indoor side of the outer wall material 15, an interior material 18 is built facing the outer wall material 15. Between the outer wall material 15 and the interior material 18, a heat insulating material and an interior base material (not shown) are disposed. A wooden picture frame 19 is attached to the opening edge of the interior material 18 over four circumferences. In FIG. 3, the frame 19 and the interior material 18 are omitted in order to make the drawing easier to see.

  The opening 1 is internally provided with a parallel protruding window 10. The parallel protruding window 10 is formed in a rectangular shape that is long in the height direction corresponding to the shape of the opening 1. The parallel projecting window 10 is provided between the frame member 2, the shoji 3 that protrudes parallel to the outdoor side with respect to the frame member 2, and the frame member 2 and the shoji 3. A plurality of link mechanisms 4 are provided (see FIG. 3).

  The frame member 2 of the parallel projecting window 10 is arranged on the four sides on the indoor side of the opening 151 of the outer wall member 15 via the attachment member 17. As shown in FIG. 4, in the frame member 2, the left and right vertical frames 21 are formed with a depth dimension from the indoor side of the outer wall material 15 to the frame 19, and are arranged on the wall body 11 by internal attachment. Has been.

  As shown in FIG. 2, the frame member 2 is assembled in a rectangular shape that is long in the height direction, corresponding to the slit-shaped opening 1. For example, the frame member 2 has a height of 2100 to 2200 mm, and the inner opening of the frame member 2 has a height of 2000 to 2100 mm by an internal method. The distance between the left and right vertical frames 21, 21 in the width direction is an internal dimension incapable of human entry, and constitutes the opening width W of the frame member 2. Specifically, the opening width W of the frame member 2 of the parallel projecting window 10 is 165 mm, and is configured to be 165 mm or less, so that it is configured as a maximum width that a person cannot enter.

  Here, in the guidelines for crime prevention building parts and the like (CP parts), as a small window that is not likely to enter, a rectangular with a long side of 400 mm and a short side of 250 mm, a long diameter of 400 mm and a short diameter of 300 mm, and a diameter of 350 mm It is required to be an internal method that does not pass any figure of the circle. On the other hand, the opening width W of the frame member 2 is a condition that is more severe than the condition of such a small window, so that there is no risk of intrusion into the opening 1 and a certain crime prevention property is ensured.

  As shown in FIG. 4, the frame member 2 is configured such that the outdoor-side finding portion 211 is disposed so as to recede to the indoor side from the outer wall material 15 and has a hug. On the four circumferences of the frame member 2, door stops 22 that abut on the shoji 3 are projected from the expected portion 212 toward the inner side of the frame member 2. Further, the door stop 22 is provided so as to recede toward the indoor side of the expected portion 212 of the frame member 2. An airtight member 23 that is in close contact with the shoji 3 is disposed at the door stop 22 (see FIGS. 5 and 6).

  As shown in FIG. 1, in the parallel projecting window 10, the shoji 3 includes an upper collar 31, a lower collar 32, and left and right vertical collars 33, and a pair glass 34 is fitted inside. A flange portion 35 extends in the outer peripheral direction at each peripheral edge portion of the upper rod 31, the lower rod 32, and the left and right vertical rods 33. As shown in FIGS. 4 to 6, the collar portion 35 is provided with an airtight material 36 on the indoor-side finding surface, and is in close contact with the collar receiving portion 24 of the frame member 2 via the airtight material 36. It is configured.

  The shoji 3 is translated in the horizontal direction to the outdoor side by the link mechanism 4 installed between the shoji 3 and the frame member 2. As the link mechanism 4, a known opening / closing member used for a parallel protruding window can be used, and the link mechanism 4 is not limited to the illustrated one.

  In the form shown in FIG. 3, the link mechanism 4 includes a frame-side bracket (not shown) provided on the vertical frame 21, a shoji-side bracket 37 provided on the outer surface of the shoji 3, and an X connecting these brackets. And a pair of link members 41 intersecting in a letter shape.

  The link member 41 is pin-connected so that the intersection of the first link 41A and the second link 41B can be freely opened and closed. One end of the first link 41 </ b> A is slidably connected to the lower end of the frame side bracket, and the other end is connected to the upper end of the shoji side bracket 37. One end of the second link 41B is slidably connected along the long hole 371 at the lower end of the shoji side bracket 37, and the other end is connected to the upper end of the frame side bracket.

  The link mechanism 4 is installed on the top, bottom, left, and right of the outer peripheral portion of the shoji 3 using the gap between the frame member 2 and the shoji 3. The link mechanisms 4 are provided on the left and right side surfaces of the shoji 3, respectively, at a plurality of locations including a middle portion and a lower portion in the height direction, thereby enabling stable translation.

  The link mechanism 4 is operated by an opening / closing handle 5 provided in the shoji 3. As shown in FIGS. 2 and 7, the opening / closing handle 5 is formed by connecting two arms 51 with a handle portion 52. On the indoor side of the vertical frame 21 of the frame member 2, a support portion 53 of the opening / closing handle 5 is provided at a substantially middle portion in the height direction. Each support portion 53 is formed so that the two arms 51 of the opening / closing handle 5 can penetrate both the indoor side and the outdoor side. The distal end portion (outdoor side) of the arm 51 penetrates the support portion 53 and is rotatably connected to a support piece 331 provided on the indoor side of the vertical arm 33 of the shoji 3.

  When opening the shoji 3, as shown in FIG. 7, the handle portion 52 is lifted around the support piece 331 to a position where the arm 51 is in a substantially horizontal posture, and pushed outward. Thereby, the link mechanism 4 is opened and extended in an X shape, and the shoji 3 is translated in parallel to the outdoor side.

  This shoji 3 is provided with a fixing means for restricting the protruding amount. In the illustrated embodiment, a pin 54 provided in the support portion 53 and a guide groove 55 in which the pin 54 travels are provided as fixing means. The guide groove 55 is formed in each arm 51 in the length direction. The tip end portion (outdoor side) of the guide groove 55 is formed in a substantially arc shape, and allows the arm 51 to rotate with respect to the support piece 331. Further, step portions 55A and 55B with which the pins 54 engage are formed in the middle portion of the guide groove 55 and the base end portion (indoor side).

  When the handle portion 52 is lifted and pushed outdoors, the pin 54 travels through the guide groove 55 and the arm 51 penetrates the support portion 53 and protrudes to the outdoor side. Thereby, the shoji 3 moves in parallel to the outdoor side. When the pin 54 is engaged with the stepped portion 55A of the guide groove 55, the shoji 3 is opened to the first opening position that is substantially flush with the outdoor surface of the outer wall material 15, as shown in FIG. It is fixed with. Further, when the handle portion 52 is lifted and further pushed outward, and the pin 54 is engaged with the step portion 55B, the shoji 3 is protruded from the outdoor surface of the outer wall member 15 as shown in FIG. It opens to the open position and is fixed in this state. That is, the amount of protrusion of the shoji 3 is regulated so that the two-stage open position can be selected by the engagement between the step portions 55A and 55B of the guide groove 55 and the pin 54.

  When closing the shoji 3, the open / close handle 5 is pulled back to retract the link mechanism 4 contrary to the above. As shown in FIG. 2, when the arm 51 is lowered to the vertical position around the support portion 53, the shoji 3 is completely closed.

  Thereby, as for the upper eaves 31 of the shoji 3, the lower eaves 32, and the vertical eaves 33, the indoor side finding part contact | abuts to the door stop 22 of the frame member 2, and the airtight material 23 closely_contact | adheres (refer FIG. 4). . Further, the collar portion 35 of the shoji 3 is in close contact with the collar receiving portion 24 of the frame member 2 through an airtight material 36. The shoji 3 is retracted to the indoor side from the indoor surface of the outer wall material 15 and is closed by the accommodation showing the expected portion of the outer wall material 15. The parallel projecting window 10 can open / close the shoji 3 by the opening / closing handle 5 and can be easily opened / closed even with one hand.

  As shown in FIG. 5, when the shoji 3 is fixed at the first open position, there is a gap between the expected portion of the opening 151 of the outer wall material 15 and the four-folded ridges (31, 32, 33) of the shoji 3. A gap S1 is formed. The gap S1 has a size of about 20 mm, for example. Therefore, the appearance is as shown in FIG. 1, the shoji 3 and the outdoor surface of the outer wall material 15 are substantially flush with each other, and it is difficult to identify whether the shoji 3 is open. Also, at first glance, the shoji 3 has an appearance that looks like a fitting window.

  Therefore, in the first open position, the opening 1 is less likely to be targeted as an intrusion target by an intruder intending in appearance. In addition, the gap S1 is so narrow that a hand, a tool, or the like cannot be inserted, so that it can be an extremely advantageous open form for crime prevention.

  In addition, as shown in FIG. 8, when the shoji 3 is in the first open position, the wind circulates between the outdoor side and the indoor side through the gaps (S1) around the four sides of the shoji 3. Thereby, ventilation and ventilation of a living room can be performed favorably. Moreover, since the crime prevention property is ensured as described above at the first open position, even if the shoji 3 is left open, it can be comfortably and comfortably spent.

  Furthermore, as shown in FIG. 6, when the shoji 3 is fixed at the second open position, it is between the expectation part of the opening 151 of the outer wall material 15 and the collar (31, 32, 33) of the shoji 3. A gap S2 is formed. The gap S2 has a size of about 50 to 60 mm, for example. The gap between the shoji 3 and the scissors 13 and the gap between the draining material 14 and the shoji 3 shown in FIG. 3 are also approximately 20 to 60 mm.

  Thereby, in the 2nd open position, sufficient ventilation can be obtained, natural air can be taken in indoors, and indoor air can be discharged outdoors. In particular, the opening 1 has a slit shape that is long in the height direction, and is provided up to the height level of the indoor floor 12 similar to the sweep-out window, so that cool air can be taken in from the feet. In addition, in the vicinity of the ceiling, the warmed air is cooled or exhausted outdoors by the wind flowing from the gap S2. This makes it possible to create a comfortable living environment without relying on air conditioning equipment.

  In the second open position, the gap S2 between the shoji 3 and the outer wall material 15 is wider than the gap S1 in the first open position. Therefore, there is room for inserting a hand into the gap S2, but even if the shoji 3 is pry open, the opening 1 is slit-shaped, and the opening width W of the frame member 2 is not large enough for humans to enter. Has been. As a result, the intrusion from the opening 1 can be completely prevented and crime prevention can be ensured.

  Moreover, since the opening part 1 is slit shape, it acts suitably also on the ventilation at the time of a strong wind. That is, as described above, since the wind is circulated through the openings 151 of the outer wall member 15 and the gaps S1 and S2 between the shojis 3, the wind does not blow from the front of the openings 1 but collides with the shojis 3 and decreases. Be forced. For this reason, even in the case of a strong wind that normally closes the shoji 3, the wind does not blow directly into the indoor side, but gently circulates from the side of the shoji 3 as shown in FIG. 8. . Therefore, the shoji 3 can be opened even during a strong wind, and good ventilation can be ensured.

  Due to the opening structure of the outer wall configured as described above, the opening 1 can have high crime prevention and good ventilation. For this reason, even if it is the outer wall in the ground floor of a building and it is a part in which the penetration | invasion from the outside is comparatively easy, it can provide suitably and can open | release in comfort.

  Moreover, according to this opening part structure, since it can provide in space saving, according to the ventilation plan of the whole building, an effective arrangement | positioning form can be implement | achieved easily. For example, the entrance and exit of the ventilation path can be provided by arranging the opening 1 so as to face a plurality of locations. Moreover, the flow of a wind can be formed in the whole building by ensuring the distance of the opening parts 1 mutually. Furthermore, the air permeability can be further enhanced by making the heights of the openings 1 different from each other.

  That is, as illustrated in FIG. 9A, the entrance door 92 is provided in one direction of the entrance hall 91, and the opening 1 a is provided in the vicinity of the side portion of the entrance door 92. Thereby, lighting and ventilation can be performed in the entrance hall 91. Moreover, the opening part 1b is provided in the wall surface which faces this opening part 1a. Thereby, the opening 1a and the opening 1b form an inlet and an outlet of the ventilation path, and a wind flow can be formed in the entrance hall 91 and a space continuous to the entrance hall 91.

  Here, as shown in FIG. 9B, the height of the opening 1b is different from that of the opening 1a in, for example, the staircase 93 arranged adjacent to the entrance hall 91. A wide flow of wind is also formed in the vertical direction, and air permeability can be improved. Moreover, the opening part 1b arrange | positioned in the position higher than the floor surface of the entrance hall 91 can enter the light from the outdoors, and can reach not only the staircase 93 but the entrance hall 91. FIG.

  Accordingly, it is possible to eliminate the conventional problem that the entrance hall becomes dark without light from the outside being inserted, and the entrance hall 91 and a living room adjacent to the entrance hall 91 can be formed in a bright and well-ventilated space. It becomes possible.

(Other embodiments)
The opening structure of the outer wall according to the present invention can be implemented in various other forms besides the above embodiment. For example, the shape of the opening 1 is not limited to the slit shape, and may be configured in any shape. Regardless of the shape of the opening 1, the opening configuration of the shoji 3 is set to the first opening position, so that both good ventilation and high crime prevention can be achieved. Therefore, the above-described embodiment is an example and is not limited.

  In addition, as shown in FIG. 10, the opening 1 can be provided with a screen door 61 on the indoor side of the shoji 3. The shoji 3 is translated and opened and closed on the outdoor side of the frame member 2 and does not protrude indoors. Therefore, the traveling rail 62 of the screen door 61 is provided on the indoor side of the door stop 22 of the frame member 2, and a roll-up roll screen door or the like can be suitably installed.

  Further, the opening 1 can be used in combination with a sliding door. For example, as shown in FIG. 11, the one-way entrance door 7 disposed on the outdoor side along the outer wall member 15 and the opening 1 can be arranged close to each other. Thereby, the lighting at the entrance portion is made possible and air permeability can be ensured even when the entrance door 7 is closed. In addition, by fixing the shoji 3 of the opening 1 at the first open position, ventilation in a state in which high crime prevention is ensured is possible. At this time, even if the opening 1 is provided on the entrance side of the entrance door 7, the shoji 3 and the outdoor surface of the outer wall material 15 are substantially flush with each other, so the shoji 3 interferes with the opening and closing of the entrance door 7. Never do. Therefore, the entrance door 7 can be opened and closed safely and smoothly.

  Moreover, the crime prevention performance in the opening part 1 can further be improved by making the kind of glass fitted in the shoji 3 into crime prevention multilayer glass, crime prevention glass, or laminated glass. Further, by using semi-transparent glass or the like, it is possible to block the line of sight toward the indoor side and ensure privacy. Furthermore, the opening 1 for ventilation in consideration of privacy can be formed by inserting the opaque board | plate material which does not have transparency, such as an aluminum panel, instead of glass in the shoji 3.

  Further, in the opening structure of the outer wall according to the present invention, the parallel protruding window 10 internally attached to the opening 1 has a parallel protruding integrally provided with a window frame 81 having a frame member as shown in FIG. It can also be formed as a window sash 8. The first opening position of the shoji 3 is configured to be substantially flush with the outdoor-side finding surface of the window frame 81. The window frame 81 is attached to the opening 1 of the wall body 11 and attached so as to be substantially flush with the outdoor surface of the wall body 11.

  Thereby, the window frame 81 can be provided in the opening part of the wall body which consists of various structures, and the parallel protrusion window sash 8 can be suitably arrange | positioned in the opening part of any building.
