Abstract

A window (10) to be provided in a building includes: a window frame (20) in which an outdoor-side opening portion (29) is set larger than an indoor-side opening portion (26); at least one surplus space section (21a) (and/or (22a)) formed inside the window frame (20) by setting the outdoor-side opening portion (29) larger than the indoor-side opening portion (26); a shoji (30) that opens and closes the indoor-side opening portion (26), between the outdoor-side opening portion (29) and the indoor-side opening portion (26); and movement mechanisms (40) that are provided between the shoji (30) and the window frame (20), to allow the shoji (30) to move between the outdoor-side opening portion (29) and the indoor-side opening portion (26). When the shoji (30) is moved from the indoor-side opening portion (26) toward the outdoor-side opening portion (29), thus opening the indoor-side opening portion (26), the surplus space section (21a) (and/or (22a)) lets an indoor side and an outdoor side of the building communicate with each other.

Description

window

The present invention relates to windows.

In the recent corona disaster, it is important to regularly ventilate the room. In the room where the room is, people pass by just outside the window, so they tend to neglect ventilation by opening the window because they are concerned about the eyes of passers-by. Of course, it is possible to open the windows after pulling the curtains, but this does not change the visibility of passers-by, and it also affects the lighting performance.

In various buildings such as detached houses and collective housing, the windows are designed to provide various functions such as lighting, ventilation, visibility, crime prevention, and insect repellency. Various types are adopted depending on the design and the intention of residents or users. For example, there are various types of windows such as sliding windows, double-hung windows, casement windows, sliding windows, tilting windows, and projecting windows. Among these types of windows, in contrast to the sliding windows that are commonly used, parallel projecting windows, which are opened by projecting from the outer wall of the building to the outside, are known as those that focus on visibility. (See Patent Document 1, for example).

JP 2014-047543 A

However, parallel projecting windows are excellent in blocking the line of sight from the outside compared to double sliding windows. There were problems such as being an obstacle for passers-by and being able to see the interior through gaps on the left and right sides.

The present invention has been made in view of the above circumstances, and can perform ventilation without worrying about the line of sight of people outside the building, including passers-by, and without disturbing passers-by. The purpose is to provide a window.

The left and right will be described as viewed from the inside of the room (inner view).

(First embodiment)
First, with reference to FIGS. 1 and 2, the overall overview of the window 10 according to the first embodiment will be conceptually described. It should be noted that FIGS. 1 and 2 do not represent the entire structure, but are intended to conceptually describe the overall overview of the window 10. FIG. A more detailed structure of the window 10 will be described separately later with reference to FIGS. 3 to 7. FIG. FIG. 1 is a front perspective view conceptually showing the window 10 in a closed state, and FIG. 2 is a rear perspective view conceptually showing the window 10 in an open state.

The window 10 includes a window frame 20 and a shoji 30, as shown in FIGS. The window frame 20 includes an upper frame 21 , a lower frame 22 , a right frame 23 , a left frame 24 , an upper back frame 25 and a lower back frame 27 . A space surrounded by the peripheral edges of the upper frame 21, the lower frame 22, the right frame 23, and the left frame 24 forms an outdoor-side opening 29, and the space extending between the upper back frame 25 and the lower back frame 27 is an indoor-side opening. forming part 26; An air tight rubber 28 is provided around the room-side opening 26 . The shoji 30 is formed from an upper rail 31 , a lower rail 32 , a right frame 33 , a left frame 34 and glass (for example, multi-layer glass) 35 .

The window 10 is provided in the building B (see FIGS. 9 to 12 described later), but as shown in FIGS. 1 and 2, the outdoor opening 29 is set wider than the indoor opening 26,

Excess spaces

21 a and 22 a are formed inside the window frame 20 by setting the outdoor-side opening 29 wider than the indoor-side opening 26 . The shoji 30 opens and closes the indoor opening 26 between the indoor opening 26 and the outdoor opening 29 . As will be described later, the shoji 30 is moved between the outdoor-side opening 29 and the indoor-side opening 26 by a moving mechanism 40 interposed between the shoji 30 and the window frame 20 . When the shoji 30 is moved from the indoor side opening 26 of the window frame 20 toward the outdoor side opening 29 and opened, the

surplus space parts

21a and 22a communicate the indoor side and the outdoor side of the building B.例文帳に追加

Here, the

redundant space portions

21a and 22a may be formed at least one location. That is, in FIGS. 1 and 2, regarding the

surplus space portions

21a and 22a, both the surplus space portion 21a inside the upper frame 21 and the surplus space portion 22a inside the lower frame 22 are formed. As will be described later, the gist of the present invention is not limited to the aspect in which both are formed, but includes aspects in which only the surplus space 21a and only the surplus space 22a are formed. That is, the

surplus spaces

21a and 22a may be provided inside the upper frame 21 and/or inside the lower frame 22 .

The window frame 20 is formed with a predetermined depth in the indoor-outdoor direction (front-rear direction), and the front surface of the window frame 20 (outdoor opening 29) is substantially aligned with the outer surface of the outer wall of the building B where the window 10 is provided. are arranged so as to be positioned substantially flush with each other. The shoji 30 can move in parallel with the indoor and outdoor directions (front and back directions) along the shoji guide rails 41 of the movement mechanism 40 provided on the right frame 23 and the left frame 24 of the window frame 20 (here , slide movement (see solid white arrows in FIGS. 1 and 2), the shoji 30 is open on the outdoor side of the window frame 20 and closed on the indoor side of the window frame 20 .

The window frame 20 is surrounded by an upper frame 21, an upper back frame 25, and a right frame 23 and a left frame 24 at positions corresponding to the upper back frame 25 above the shoji 30 (inside the upper frame 21 side of the window frame 20). A surplus space portion 21a, which is a closed space, is provided. Similarly, below the shoji 30 (inside the lower frame 22 side of the window frame 20), the lower frame 22, the lower back frame 27, the space surrounded by the right frame 23 and the left frame 24 at positions corresponding to the lower back frame 27 A surplus space portion 22a is provided. In other words, the

surplus spaces

21a and 22a form a space separate from the space in which the shoji 30 moves as it opens and closes. When the shoji 30 is moved from the indoor side opening 26 toward the outdoor side opening 29 and opened (see FIG. 2), the outdoor side of the window 10 is opened through the

redundant space portions

21a and 22a and the indoor side opening 26. and the indoor side communicate with each other, and ventilation is performed. On the other hand, when the shoji 30 is closed to the indoor side (see FIG. 1), the indoor-side opening 26 of the window frame 20 is closed by the shoji 30, and the outdoor side and the indoor side of the window 10 are blocked.

A more detailed structure of the window 10 will be described below with reference to FIGS. 3 to 7. FIG. 3 is a front view of the window frame 20, FIG. 4 is a rear view of the shoji 30, FIG. 5 is a vertical cross-sectional view of the window 10, FIG. The front view of the crime prevention mechanism 50 (surface grating) arrange|positioned outside is shown, respectively. The gist of the present invention is not limited to the aspects shown in FIGS. 3 to 7, and various modifications can be added.

As shown in FIG. 3, the window frame 20 is formed in a vertically long rectangle with an aspect ratio when viewed from the front. The shape of the window frame 20 when viewed from the front is not limited to this, and depending on the conditions and environment of the building B in which it is installed, the contour may be square, circular, or irregular, or may be long in aspect ratio. may be In short, it is sufficient that the

surplus spaces

21a and 22a and the indoor opening 26 are provided so that the outdoor side and the indoor side of the window 10 communicate with each other when the shoji 30 is opened. The shapes of the

surplus space portions

21 a and 22 a and the indoor-side opening portion 26 can also be appropriately selected according to the shape of the window frame 20 and the shoji screen 30 .

The main purpose of the window 10 is that it can be opened for ventilation without worrying about the line of sight of passers-by passing through the outside of the window 10. Therefore, as shown in FIG. The left and right sides of the window frame 20, that is, between the right and left

frames

23 and 24 and the shoji 30, which correspond to the height of the general line of sight of passers-by, are not at the height of the general line of sight of passers-by. It is provided above and below the window frame 20 that does not correspond, that is, between the upper frame 21 and the lower frame 22 and the shoji 30 .

The shoji 30 is moved by a moving mechanism 40 interposed between the shoji 30 and the window frame 20. In the first embodiment, the moving mechanism 40 moves the shoji 30 parallel to the window frame 20. The entire shoji 30 is slidably moved so as to be carried out.

Specifically, as shown in FIG. 3, between the left and right of the window frame 20, that is, between the right frame 23 and the left frame 24 and the shoji 30, a gap necessary for moving the shoji 30 is provided. Shoji guide rails 41 and housings 42 engaged with the shoji guide rails 41 are provided at the four corners of this gap (near the four corners of the indoor opening 26 in the figure) as a moving mechanism 40 for moving the shoji 30. are placed. The shoji guide rail 41 is provided at a position where

surplus spaces

21a and 22a are secured above and below the right frame 23 and the left frame 24, respectively. The housings 42 are slidably engaged with the shoji guide rails 41 while being fixed to the four corners of the shoji 30, respectively. The strength of the frictional force is adjustable. The shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the upper back frame 25 or the lower back frame 27, and the range of movement of the shoji 30 is restricted by them.

Although the moving mechanism 40 is a slide mechanism in the first embodiment, the moving mechanism 40 is not limited to this. For example, a link mechanism that combines a plurality of link pieces or an arm mechanism that extends and contracts in the front-rear direction may be employed. In short, it is also possible to make the moving mechanism 40 capable of reciprocating between the outdoor side and the indoor side of the window frame 20 . However, the slide mechanism is preferable in terms of the operability of the shoji 30, especially the force required for the movement in the front-rear direction.

As shown in FIG. 4, the shoji 30 is, for example, square when viewed from the rear (the same is true for the front view). Here, the shoji 30 is square with respect to the vertically long window frame 20, but the shape of the shoji 30 when viewed from the rear (front view) is not limited to this. It may have a rectangular, circular or irregular shape in outline, and may have a vertical or horizontal aspect ratio. For example, when the window frame 20 has a square shape, if

extra space portions

21a and 22a are secured above and below the window frame 20, the shoji 30 will have a horizontally long rectangular aspect ratio.

A cam latch handle 36 is provided at the center of the back surface of the right frame 33 and the left frame 34 of the shoji 30 to lock the shoji 30 to the window frame 20 and to serve as a handle for moving the shoji 30 in the front-rear direction. . The cam latch handle 36 is provided so that the handle body is "closed" in the vertical state and "open" in the horizontal state. The shoji 30 is locked to the window frame 20 by engaging with a locking member provided on the back surface of the door 20. - 特許庁

In addition, in FIG. 4, in order to explain the positional relationship, a shoji guide rail 41 as a moving mechanism 40 and a housing 42 that engages with the shoji guide rail 41 are shown above and below the right frame 33 and left frame 34 of the shoji 30. It is

Based on the above structure, the ventilation at the window 10 will be explained. As shown in FIGS. 5 and 6, the shoji 30 moves forward and backward on the outside and inside of the window frame 20 (see solid white arrows in FIGS. 5 and 6). As described above, the front surface of the window frame 20 (outdoor opening 29) is arranged so as to be substantially flush with the outer surface of the outer wall of the building B in which the window 10 is provided. It is positioned substantially flush with the outer surface of the outer wall of building B when opened to the maximum extent.

When the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the outdoor side of the window 10 passes through the

redundant space portions

21a and 22a and the indoor-side opening 26. and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 5). The shoji 30 is provided so as to be steplessly stopable with respect to the window frame 20 between the indoor side and the outdoor side of the window frame 20.例文帳に追加During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the

surplus spaces

21a and 22a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but it is a gentle crank. shape.

FIG. 5 and FIG. 6 show an example in which a surface lattice 51 with a screen door is provided on the outdoor side of the window frame 20 as the crime prevention mechanism 50 . FIG. 7 shows the appearance of the screen door-equipped lattice 51 viewed from the front. The screen door-equipped screen door 51 is composed of a screen door 51 (sometimes referred to as a screen door 51 in a narrow sense) and a screen door 52 attached to the screen door 51 . The window 10 is arranged so that the shoji 30 in the maximum open state is substantially flush with the outer surface of the outer wall of the building B, so that the window 10 projects outward from the outer surface of the outer wall of the building B. However, by adding the surface lattice 51, the crime prevention performance can be further improved. Moreover, if the surface lattice 51 with a screen door is used, it is also possible to achieve insect repellency especially in summer. However, the lattice 51 and the screen door 52 may be provided separately. For example, only the lattice 51 is provided on the outdoor side of the window frame 20, and the roll-up screen door 52 is provided on the indoor side of the window frame 20. You may make it provide.

In FIG. 5, for convenience of explanation, the cam latch handle 36 of the shoji 30 in the open state is omitted, but as shown in FIG. 6, the cam latch handle 36 is positioned horizontally.

As shown in FIG. 5, the

surplus spaces

21a and 22a open from the indoor side toward the outdoor side as part of the outdoor side opening 29 in a vertical cross-sectional view. The outer contours of the

surplus spaces

21a and 22a are defined by the contour of the window frame 20, but the specific shape thereof may vary. In FIG. 5 , when stepped (here, L-shaped) from the peripheral edge (upper edge, lower edge) of the indoor side opening 26 toward the peripheral edge (upper edge, lower edge) of the outdoor side opening 29 is shown. Supplementally, the two sides of the substantially horizontal upper frame 21 and the substantially vertical upper back frame 25, and the two sides of the substantially horizontal lower frame 22 and the substantially vertical lower back frame 27 respectively intersect. As a result, the outer contours of the

surplus spaces

21a and 22a are stepped (here, L-shaped).

In this regard, in the window 10, as described above, the flow of the air A is in a gentle crank shape, so as shown in FIG. The upper frame 21 and the lower frame 22 may be shaped obliquely or arcuately from the rim of the indoor opening 26 toward the rim of the outdoor opening 29 in consideration of smoothing the contours of . This makes it possible to guide the flow of the air A relatively smoothly. Depending on the design requirements of the window 10, the upper frame 21 and the lower frame 22 may be formed in a combination of steps, oblique lines, or arcs as long as ventilation is not hindered.

Although the configuration of the window 10 has been described above, depending on the conditions and environment in which the window 10 is installed, when the shoji 30 is opened, a passerby may enter the room of the building B through the

surplus spaces

21a and 22a and the indoor opening 26. It is also conceivable that the line of sight of Therefore, the visibility of the window 10 will be described with reference to FIGS. 9 to 12. FIG.

FIGS. 9 to 12 illustrate four cases regarding the line-of-sight relationship between the window 10 and the passerby P (whose height H1 is assumed to be about 170 cm).

FIG. 9 illustrates a case where the vertical length L of the window 10 is relatively long (assumed to be about 160 cm) and the

surplus spaces

21a and 22a are curved (L-shaped). The center height H2 in the vertical direction is assumed to be approximately 150 cm. In this example, the range (upper visibility) where the interior of the building B can be seen through the surplus space 21a inside the upper frame 21 and the interior opening 26 is the line of sight U1 (the upper edge of the upper rail 31 of the shoji 30 in the open state). A line connecting the upper edge of the indoor-side opening 26 of the window frame 20) and the line of sight U3 (the outdoor-side tip of the surplus space 21a <peripheral edge of the outdoor-side opening 20> and the upper crosspiece 31 of the open shoji 30 The line connecting the edge) is the boundary line. This range includes the line of sight U2 (the line connecting the outdoor-side tip of the surplus space 21a and the upper edge of the indoor-side opening 26 of the window frame 20). Similarly, the range (lower visibility) where the interior of the building B can be seen through the surplus space 22a inside the lower frame 22 and the interior opening 26 is the line of sight D1 (the lower edge of the lower rail 32 of the shoji 30 in the open state and the window A line connecting the lower edge of the indoor-side opening 26 of the frame 20) and a line of sight D3 (a line connecting the outdoor-side tip of the surplus space 22a and the lower edge of the lower beam 32 of the shoji 30 in the open state). range. This range includes the line of sight D2 (the line connecting the outdoor-side tip of the surplus space 22a and the lower edge of the indoor-side opening 26 of the window frame 20).

In this example, as shown in FIG. 9, a field of view is formed through the

surplus spaces

21a and 22a and the room-side opening 26, but the line of sight of a normal passer-by P is out of the field of view both above and below the window 10. It will be. In this case, the vertical width of the upper crosspiece 31 and the lower crosspiece 32 of the shoji 30 can be set narrow.

FIG. 10 illustrates a case where the vertical length L of the window 10 is relatively short (assumed to be about 115 cm) compared to FIG. The center height H2 in the vertical direction is assumed to be approximately 140 cm. In this example, the ends of the

excess spaces

21a and 22a, the upper edge of the upper rail 31, and the lower edge of the lower rail 32, which define the upper and lower fields of view of the window 10, are close to the line of sight of the passerby P. Therefore, depending on the height H1 of the passerby P, the possibility that the interior of the building B can be seen through the

surplus spaces

21a and 22a and the interior opening 26 increases. Therefore, in FIG. 10, the line of sight U1 (the outdoor side of the surplus space 21a) is set above the window 10 so that the field of view is not formed both above and below the window 10, that is, so that a plurality of lines of sight that serve as boundaries are not formed. A line connecting the top edge of the shoji 30 in the open state and the upper edge of the upper beam 31 of the shoji 30 and the upper edge of the room-side opening 26 of the window frame 20), and below the window 10, the line of sight D1 (the room of the surplus space 22a). A line that connects the outer tip, the lower edge of the lower rail 32 of the shoji 30 in the open state, and the lower edge of the indoor-side opening 26 of the window frame 20).

In this example, as shown in FIG. 10, by setting the width of the upper beam 31 and the lower beam 32 of the shoji 30 in the vertical direction to be wide, the line of sight above and below the window 10 is unified, and the

surplus spaces

21a and 22a are formed. And the view through the interior opening 26 is not formed.

FIG. 11 illustrates a case where the vertical length L of the window 10 is relatively short (assumed to be about 97 cm) compared to FIG. The center height H2 in the vertical direction is assumed to be approximately 140 cm. In this example, the unification of the line of sight shown in FIG. 10 is limited to the top of the window 10. The purpose of this is to assume that the passerby P is an adult, and that the line of sight of a child with a short height H1 is not dealt with. It can be said that In this example, above the window 10, the line of sight U1 (the tip of the outdoor side of the surplus space 21a, the upper edge of the upper rail 31 of the shoji 30 in the open state, and the upper edge of the indoor opening 26 of the window frame 20) The line of sight is not formed under the window 10, and the line of sight D1 (the lower edge of the lower crosspiece 32 of the shoji 30 in the open state and the room-side opening 26 of the window frame 20) edge) and the line of sight D3 (outdoor-side tip of the surplus space 22a, the lower edge of the lower beam 32 of the shoji 30 in the open state, and the room of the frame of the building B corresponding to the indoor-side opening 26 of the window frame 20) A field of view surrounded by a line connecting the inside is formed.

In this example, as shown in FIG. 11, by setting the upper crosspiece 31 of the shoji 30 wide in the vertical direction, the line of sight above the window 10 is unified, and the surplus space 21a and the indoor opening 26 are arranged. A view through is not formed. On the other hand, by setting the vertical width of the lower crosspiece 32 of the shoji 30 narrowly, a field of view through the extra space 22a and the interior opening 26 is formed.

12, the vertical length L of the window 10 is relatively short (assumed to be about 95 cm), the surplus space 21a inside the upper frame 21 is curved (L-shaped), and the surplus space 22a inside the lower frame 22. is oblique. The center height H2 in the vertical direction is assumed to be approximately 130 cm. In this example, above the window 10, the width of the upper beam 31 of the shoji 30 in the vertical direction is not set wider than in FIGS. A line connecting the upper edge and the upper edge of the indoor-side opening 26 of the window frame 20) and a line of sight U3 (a line connecting the outdoor-side tip of the surplus space 21a and the upper edge of the upper beam 31 of the shoji 30 in the open state) ) is formed as a boundary line. Under the window 10, as in FIG. 11, the line of sight D1 (the line connecting the lower edge of the lower crosspiece 32 of the shoji 30 in the open state and the lower edge of the interior-side opening 26 of the window frame 20) and the line of sight A field of view is formed with a boundary line D3 (a line connecting the outside edge of the surplus space 22a and the inside of the frame of building B corresponding to the inside opening 26 of the window frame 20).

In this example, as shown in FIG. 12, by setting the width of the upper crosspiece 31 of the shoji 30 in the vertical direction to be slightly wider, the field of view through the surplus space 21a and the indoor opening 26 is narrowed, thereby If P is an adult of average height H1, his line of sight will be out of sight above window 10 . On the other hand, by setting the vertical width of the lower crosspiece 32 of the shoji 30 narrowly, a field of view through the extra space 22a and the interior opening 26 is formed.

Regarding the visibility of the window 10, as described above, it is possible to take various measures depending on the relative positional relationship between the window 10 and the building B and the specifications of the window 10. In preparation for the case where the is inevitably included in the field of vision of the window 10, the barrier 30 is separated from the indoor side opening 26 of the window frame 20 to the outdoor side within the range of achieving both ventilation and visibility of the window 10. A shielding mechanism 60 that improves the shielding performance in the

surplus spaces

21a and 22a when moved toward the opening 29 and opened may be further provided.

FIGS. 13 to 16 illustrate two cases of shielding flaps 62 as examples of the shielding mechanism 60. FIG. 13 is a longitudinal sectional view showing the shielding flap 62, FIG. 14 is a perspective view showing an enlarged part thereof, FIG. 15 is a longitudinal sectional view showing another example of the shielding flap 62, and FIG. 16 is a part thereof. 1 is an enlarged perspective view of FIG. Although these figures show only the upper frame 21 of the window frame 20, a similar shielding mechanism 60 may be provided on the lower frame 22 of the window frame 20 as required.

As shown in FIG. 13, the shielding mechanism 60 includes a pair of flap guide rails 61 provided at positions corresponding to the surplus spaces 21a of the right frame 23 and the left frame 24 of the window frame 20, and the flap guide rails 61. and a shielding flap 62 that is slidably engaged and moves in the front-rear direction along the flap guide rail 61 as the shoji 30 moves in the front-rear direction.

The flap guide rail 61 extends so as to incline slightly downward from the indoor side of the window frame 20 toward the outdoor side, leaving a range covered by the shielding flap 62 . A space is widened between the pair of left and right flap guide rails 61, which does not hinder ventilation. On the other hand, the blocking flap 62 is a plate-like member and blocks the field of view. As will be described later, the shielding flap 62 is attached to the top of the upper rail 31 of the shoji 30 so as to be foldable. In the open state, it inclines slightly downward from the indoor side to the outdoor side so as to partially block the view through the surplus space portion 21a and the indoor side opening portion 26. - 特許庁

FIG. 13 shows the visibility of the shielding flap 62 when the shoji 30 is fully opened to the outside, taking the field of view in FIG. 9 as an example. In the surplus space 21a, the shielding flap 62 is positioned along the line of sight U1 (the upper edge of the upper beam 31 of the shoji 30 in the open state <outdoor-side tip of the shielding flap 62> and the upper edge of the indoor-side opening 26 of the window frame 20). ), the line of sight U3 (the line connecting the tip of the surplus space 21a on the outdoor side and the upper edge of the upper rail 31 of the shoji 30 in the open state <the tip of the outdoor side of the shielding flap 62>), the line of sight U2 (the surplus The line connecting the outdoor-side tip of the space 21a, the indoor-side tip of the shielding flap 62, and the upper edge of the indoor-side opening 26 of the window frame 20) obstructs the field of view in the area surrounded.

FIG. 14 shows a specific example of the shielding flap 62. FIG. The shielding flap 62 is provided with a sliding member 64 at its upper end (when the shoji 30 is opened, it becomes the tip of the room inside <indicated by solid line in the figure>), and the sliding member 64 is formed in a U-shape. It is slidable along the formed flap guide rail 61 . The shielding flap 62 is attached to the top of the upper beam 31 of the shoji 30 via a hinge 63 at its lower end (the tip of the outdoor side when the shoji 30 is opened <indicated by the solid line in the figure>). , the hinge 30 allows the shielding flap 62 to be tilted with respect to the upper crosspiece 31 according to the longitudinal movement of the shoji 30. - 特許庁As a result, when the shoji 30 is opened <indicated by a solid line in the figure>, the shielding flap 62 faces the direction of blocking the line of sight, and when the shoji 30 is closed <indicated by a broken line in the figure> It stands up along the upper back frame 25 and does not interfere with the opening and closing of the shoji 30. - 特許庁

15 and 16 show another example of the blocking flap 62. FIG. The shielding mechanism 60 is intended to achieve both ventilation and shielding properties of the window 10. In this other example, the shielding flap 62 is made of a plate-like material. , the shielding flap 62 itself is intended to have ventilation.

That is, in this other example, as shown in FIGS. 15 and 16, the shielding flap 62 has a ventilation plate 65 that naturally opens due to gravity when the shielding flap 62 is tilted. The ventilation plate 65 is rotatably attached to the shielding flap 62 so that it naturally hangs vertically when the shielding flap 62 is tilted. As a result, visibility is ensured by the hanging ventilation plate 65, and ventilation is performed through the space created by the opening of the ventilation plate 65. - 特許庁As shown in an enlarged view in FIG. 16, the ventilation plate 65 hangs down in the vertical direction when the shoji 30 is opened (indicated by solid line in the figure), and when the shoji 30 is closed (indicated by broken line in the figure). Display> stands along the upper back frame 25 integrally with the shielding flap 62 so as not to interfere with the opening and closing of the shoji 30.例文帳に追加

Although the window 10 has been described above, the following modifications are also possible. That is, depending on the relative relationship with other windows provided in the same room or another room of the building B, in one window 10, the surplus space part 21a inside the upper frame 21 and the surplus space part 21a inside the lower frame 22 A configuration in which one of the space portions 22a is provided may be employed. For efficient ventilation, a plurality of windows, for example, two windows on a diagonal line may be opened at the same time. It is not necessary to provide both the space 21a and the extra space 22a inside the lower frame 22, as long as at least one

extra space

21a or 22a is provided.

Further, in the above description, the front surface of the window frame 20 (outdoor opening 29) and the position of the shoji 30 when opened to the maximum are substantially flush with the outer surface of the outer wall of the building B in which the window 10 is provided. However, depending on the specifications of the building B in which the window 10 is installed and the surrounding environment of the building B, this need not necessarily be the case. For example, the front surface of the window frame 20 (outdoor opening 29) and the shoji screen 30 when opened to the maximum extent may extend from the outer surface of the outer wall of the building B to the outdoor side if the distance between the window 10 and the passerby P can be secured. It may be placed in a protruding position, or in the case of providing a flower bed space on the outside window side, it may be placed in a position pulled into the room.

(Second embodiment)
The window 10 according to the first embodiment and its modification has been described above. Next,

windows

10A and 10B according to the second embodiment will be described with reference to FIGS. 17 to 22. FIG. In the window 10 according to the first embodiment, when the

excess space portions

21a and 22a are provided inside the upper frame 21 and/or inside the lower frame 22 of the window frame 20 (that is, only inside the upper frame 21 and only inside the lower frame 22 , inside the upper frame 21 and inside the lower frame 22), the moving mechanism 40 slidably moves the entire shoji 30 so that the shoji 30 is opened parallel to the window frame 20. In contrast, the

windows

10A and 10B according to the second embodiment are provided with the

redundant space portions

21a and 22a inside the upper frame 21 or inside the lower frame 22 of the window frame 20 (that is, the upper frame 21 inside only, and lower frame 22 only inside), the movement mechanism 40 can rotate the upper or lower part of the shoji 30 so that the shoji 30 is tilted vertically with respect to the window frame 20 and opened. is to be moved to

The gist of the present invention is not limited to the embodiments shown in FIGS. 17 to 22, and various modifications can be made. Differences from the window 10 according to the first embodiment will be mainly described below.

First, in the window 10A, as shown in FIG. 17, only the extra space 21a inside the upper frame 21 of the window frame 20 is provided. Inside the lower frame 22, there is no extra space 22a for positive ventilation. As shown in FIG. 18, the shoji 30 is provided with hinges 43 as a moving mechanism 40 at the left and right ends of the lower beam 32, and is rotatably attached to the lower portions of the right frame 23 and the left frame 24 of the window frame 20. be done. A cam latch handle 36 provided on the rear surface of the shoji 30 is positioned closer to the upper crosspiece 31 from the vertical center of the right frame 33 and the left frame 34 .

Based on the above structure, the ventilation at the window 10A will be explained. As shown in FIG. 19, when the cam latch handle 36 of the shoji 30 is pushed to the outside of the room, the hinge 43 provided on the lower beam 32 serves as a fulcrum, and the upper beam 31, which is the upper part of the shoji 30, opens to the indoor side. 26 from the peripheral edge (upper edge) of 26 to the outdoor side (see the solid white arrow in FIG. 19), and tilts up and down with respect to the window frame 20 to be opened. The upper beam 31 moved to the outdoor side is substantially the same as the front surface of the window frame 20 (outdoor opening 29), and thus the outer surface of the outer wall of the building B where the window 10A is provided, in the maximum open state. located on the surface.

When the upper beam 31 of the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the window 10A is opened through the surplus space 21a and the indoor-side opening 26. The outdoor side and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 19). During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the excess space 21a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but has a gentle crank shape. Become.

Although not shown here, the upper crosspiece 31 of the shoji 30 may be configured to be free with respect to the window frame 20, or may be configured to be constrained. When the upper beam 31 of the shoji 30 is set free with respect to the window frame 20 , the upper beam 31 of the window frame 20 is regulated at the position of the outdoor opening 29 . The window frame 20 may be provided with a stopper, or the window frame 20 and the shoji 30 may be connected by an extendable arm. On the other hand, when restraining, the shoji guide rail 41 shown in the window 10 according to the first embodiment is provided on the right frame 23 and the left frame 24 so as to be inclined downward from the indoor side to the outdoor side. may be slidable through the housing 42 by the . In this case, the shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the upper back frame 25, and the range of movement of the shoji 30 is restricted by them.

Next, in the window 10B, as shown in FIG. 20, only an extra space 22a inside the lower frame 22 of the window frame 20 is provided. Inside the upper frame 21, there is no surplus space 21a for positive ventilation. As shown in FIG. 21, the shoji 30 is provided with hinges 43 as a moving mechanism 40 at the left and right ends of the upper crosspiece 31, and is rotatably attached to the upper part of the right frame 23 and the left frame 24 of the window frame 20. be done. A cam latch handle 36 provided on the rear surface of the shoji 30 is positioned closer to the lower rail 32 from the vertical center of the right frame 33 and the left frame 34 .

Based on the above structure, the ventilation at the window 10B will be explained. As shown in FIG. 22, when the cam latch handle 36 of the shoji 30 is pushed to the outside of the room, the hinge 43 provided on the upper beam 31 serves as a fulcrum, and the lower beam 32, which is the lower part of the shoji 30, opens to the indoor side. 26 from the peripheral edge (lower edge) of 26 to the outside of the room (see the solid white arrow in FIG. 22), and tilts vertically with respect to the window frame 20 to be opened. The lower beam 32 moved to the outdoor side is substantially the same as the front surface of the window frame 20 (outdoor opening 29) and the outer surface of the outer wall of the building B in which the window 10B is provided in the maximum open state. located on the surface.

When the lower rail 32 of the shoji 30 moves from the indoor-side opening 26 of the window frame 20 toward the outdoor-side opening 29 and is opened, the window 10B is opened through the surplus space 22a and the indoor-side opening 26. The outdoor side and the indoor side communicate with each other, and ventilation is performed (see the broken white arrow in FIG. 22). During ventilation, the air A flows from the outdoor side to the indoor side or from the indoor side to the outdoor side depending on the relative relationship with other windows provided in the building B. Since the vertical positional relationship between the surplus space 22a and the room-side opening 26 is not parallel, the flow of the air A is actually not as sharp as indicated by the dashed white arrow in the figure, but has a gentle crank shape. Become.

Although not shown here, the lower beam 32 of the shoji 30 may be configured to be free with respect to the window frame 20, or may be configured to be constrained. When the lower rail 32 of the shoji 30 is free from the window frame 20, the lower rail 32 of the window frame 20 is regulated at the position of the outdoor opening 29. The window frame 20 may be provided with a stopper, or the window frame 20 and the shoji 30 may be connected by an extendable arm. On the other hand, when restraining, the shoji guide rail 41 shown in the window 10 according to the first embodiment is provided on the right frame 23 and the left frame 24 so as to be inclined upward from the indoor side to the outdoor side. may be slidable through the housing 42 by the . In this case, the shoji guide rails 41 extend between the periphery of the outdoor opening 29 and the lower back frame 27, and the range of movement of the shoji 30 is restricted by them.
