Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a device for forming a daylighting space by bulging out from a bay window, a greenhouse, or other building opening. The present invention relates to a lighting space forming device.

``Conventional technology'' In recent years, with the diversification of individual housing and the increasing luxury of apartment complexes, openings in building frames have been Various devices such as bay windows and greenhouses that bulge outward to form a daylighting space have been proposed, but this type of daylighting space forming device, for example, as shown in Fig. A roof body 2 and a base plate body 3 are provided protrudingly on the roof body 1, and bundle columns 4 are supported perpendicularly at arbitrary intervals on the peripheral surface between the roof body 2 and the base plate body 3. A window frame 5 is attached to a rectangular space surrounded by the casings 2 and 3 to form a lighting section.

"Problems to be Solved by the Invention" However, in this way, the bundle pillars 4 are supported orthogonally at the corners of the upper and lower roof bodies 2 and the ground plate body 3, which are formed in a trapezoidal shape, for example, and the bundle pillars 4 Attaching the window frame 5 to the front and both side surfaces surrounded by both the roof bodies 2 and the ground plate body 3 means that the natural lighting space is divided by the bundle pillars 4, giving a feeling of being narrow and unfavorable from a viewing angle. At the same time, attaching the window frame 5 to each side divided by the bundle pillars 4 increases the number of parts, which increases the weight burden of the bay window itself and complicates the on-site work.

For this reason, in narrow bay windows such as triangular bay windows, attempts have been made to form the lighting surface using only the window frame 5 and the glass plate material attached to the window frame 5, without providing the bundle pillars 4. However, in trapezoidal bay windows, etc., where the front opening has a wide area of daylight, the glass itself is vulnerable to vibrations and shocks, so it may be damaged by the weight of the roof frame applied from the top of the glass. Therefore, in order to have a load-bearing property sufficient to withstand the above-mentioned own weight, the wall thickness must be increased accordingly, resulting in the problem of increased weight burden and manufacturing cost.

Furthermore, as mentioned above, glass is extremely susceptible to impact forces, so it is impossible to attach it directly to rigid bodies such as the roof body 2 and the base plate body 3. Generally, the window frame 5 with a cushion material or the like interposed therein is used. It is necessary to first form the window frame 5 and then attach the window frame 5 to the roof frame, etc., which leads to an increase in the number of parts and on-site man-hours.

In view of the drawbacks of the prior art, the present invention enables the lighting space sandwiched between the pair of upper and lower roof bodies protruding from the outer wall of the building and the ground plate to form a continuous lighting surface without being divided by bundled columns or the like. Another object of the present invention is to provide a lighting space forming device in which a window portion through which outside air can be taken in is provided at any location on the lighting surface.

Another object of the present invention is to provide a lighting space forming device that is lightweight, has a small number of parts, and can be made into a unit.

"Means for Solving the Problems" In order to achieve such technical problems, the present invention provides a roof body that projects almost horizontally toward the outdoors from the upper side of a rectangular opening formed on the outer wall of a building; A ground plate body protruding almost horizontally toward the outdoors from the lower side of the square opening, and a ground plate body extending from one side side of the square opening in order to partition the area where the roof body and the ground plate face each other from the outdoors. , extending while being bent along the periphery of the lower surface of the roof body and the periphery of the upper surface of the ground plate, respectively, and arranged so as to reach the other side of the rectangular opening, the horizontal cross-sectional shape being approximately trapezoidal. A translucent polycarbonate board, a part of the carbonate board parallel to the building's outer wall and other faces is opened, a frame that functions as a window frame is installed along the edge of the opening, and a frame that functions as a window frame is installed along the edge of the opening. We propose a lighting space forming device characterized by forming a window section that can be opened and closed.

That is, the main configuration of the present invention is that the framework 50 is not supported by a bundle pillar but by the opening edge of a polycarbonate plate, and a window portion that can be opened and closed is formed within the framework. In this case, the window portion that can be opened and closed does not necessarily refer to the window portion 60 as shown in the embodiment described later.
In addition to the case where the window section 60 is configured to be slidable along the framework 50, it also includes the case where the window section is formed into a disk shape and can be opened and closed by rotating the window section.

"Operation" According to this technical means, a roof is installed in the facing area between the roof body 20 and the ground plate body 30, which are arranged on the upper side and the lower side of the rectangular opening formed on the outer wall of the building, to separate it from the outdoors. Since the translucent polycarbonate plate 40 is bent along the periphery of the lower surface of the body 20 and the lower surface of the main plate 30 and extends from one side of the rectangular opening to the other side, the opening A continuous lighting surface can be formed without the surface being divided by bundled columns.

That is, since the polycarbonate plate 40 has impact resistance strength 400 times that of glass, the polycarbonate plate 40 itself has a pair of upper and lower roof bodies 20 and a base plate body 30.
It can function as a bundle pillar supporting the space between the windows, and even when forming a wide trapezoidal bay window, a continuous lighting surface that is not divided by the bundle pillars can be formed.

Further, the polycarbonate plate 40 is not flat, but is bent to match the peripheral shapes of the roof body 20 and the base plate body 30, so it is three-dimensional.
0a makes it possible to further firmly support the pair of upper and lower roof bodies 20 and base plate body 30, and thereby the wide polycarbonate plate 40 does not sway even due to vibrations or wind, making it more solid. It is possible to support it.

Further, in the present invention, the frame body 50 functioning as a window frame is supported on the opening edge of the polycarbonate plate 40, in other words, it is supported as if it were hollow above the daylighting space, so that the following effects are derived.

That is, in the prior art, the installation space for the frame 50 is limited to the rectangular space surrounded by the bundle pillars 4, the roof body 2, and the base plate body 3, and therefore the area and shape of the window frame forming space are inevitably limited. Although limited, in this technical means, since the window frame 5 is substantially hollowly supported on the lighting surface formed by the polycarbonate plate 40, the shape, area and mounting position of the window frame space can be arbitrarily determined. And it can be set freely.

As a result, the degree of freedom in design is increased, and the openable and closable window portion 60 can be freely formed in the most favorable opening area and position for ventilation according to each purpose. Accordingly, the lighting space can function as a bay window or a greenhouse.

In addition, since the polycarbonate plate 40 has impact resistance 400 times that of glass, there is no need to worry about the strength even if the frame 50 is directly supported on the polycarbonate plate 40 as described above.
Because it has impact resistance, it can be directly attached to the roof body 20 and the base plate body 30 without intervening cushioning material, which reduces the number of parts and weight burden, and facilitates assembly. At the same time, the entire device can be made into a unit.

"Embodiments" Hereinafter, preferred embodiments of the present invention will be described in detail by way of example with reference to the drawings. However, the dimensions, materials, shapes, relative positions, etc. of the components described in this example are as follows, unless otherwise specified.
This is not intended to limit the scope of the invention, but is merely an illustrative example.

Figures 1 and 2 show an embodiment of the present invention in which a bay window unit body is attached to the outside of a rectangular frame opening formed on the outer wall of an existing building. Figure 1 is an overall perspective view of the unit; The figure shows an enlarged view of the main part of FIG.

A roof body 20 that protrudes, a base plate body 30 that protrudes substantially horizontally toward the outdoors from the lower side of the outer frame 11, and an area where the roof body 20 and the base plate body 30 face each other is partitioned from the outdoors. ,
It extends from one side of the outer frame 11 while being bent along the periphery of the lower surface of the roof body 20 and the periphery of the upper surface of the base plate 30, respectively, and extends from the other side of the outer frame 11. A translucent polycarbonate plate 40 having a substantially trapezoidal horizontal cross section is provided, and the carbonate plate 40 has an opening in the center of its front face parallel to the outer wall of the building, and a translucent polycarbonate plate 40 is provided along the edge of the opening. A frame 50 functioning as a window frame is attached to the frame 50.
A window portion 60 that can be opened and closed is formed inside.

The outer frame 10 of the bay window unit 7 is constructed so that it can be fixed on the outer wall surface 1 around the building opening 2 with anchor bolts, etc., and has the pair of roof bodies 20 and the base plate 30 on each of its upper and lower sides. , and the proximal end sides of polycarbonate plates 40 are fixed to each of the left and right sides thereof.

The roof body 20 and the base plate body 30 are formed by bending or welding aluminum plates or other metal plates, and have their base ends fixed to the edge surface of the outer frame 10, and are slightly inclined toward the center so as to be outwardly shaped. The roof body 2
The lighting surface formed along the periphery between 0 and the ground plate 30 is formed to have a trapezoidal cross section. Then, the peripheral edges of the roof body 20 and the free end side of the base plate body 30 are bent into a U-shape as shown in FIG. The ends of the polycarbonate plate 40 are sealed and fixed using the polycarbonate plate 40.

The polycarbonate board 40 is made by forming a transparent, semi-transparent or partially translucent board material into a trapezoidal horizontal cross section along the mounting surface 21 formed along the peripheral line of the roof body 20 and the base plate body 30, and A rectangular opening is opened at the center of the front surface parallel to the outer wall, and a framework 50 is attached to the opening edge 42.

As shown in FIG. 2, the framework 50 has an engagement groove 51a in which the open end 42a of the polycarbonate plate 40 can engage, and a window 60 on the front side of the engagement groove 51a in parallel with the engagement groove 51a. A pair of fitting grooves 5 to be fitted
Aluminum or other shaped material 51 having 1b, 51c
After cutting the mold material 51 to fit each side of the opening, open end portions 42 forming the respective sides are cut.
a is engaged with the engagement groove 51a to support and fix the framework 50 on the polycarbonate plate 40, and a pair of windows 60 that are vertically slidable are provided in the engagement grooves 51b and 51c of the framework 50. Make it fit.

The window portion 60 is formed by using a polycarbonate plate 40 cut into approximately the same shape as the upper and lower halves of the opening 42, and has guide ends fitted to the fitting grooves 51b and 51c on both left and right ends of the carbonate plate 40. 61, and a lattice-shaped frame beam 62 is attached to the front side portion sandwiched between the guide ends.

According to this embodiment, the framework 50 is directly supported by the opening 42 formed at the center of the front side 41 of the polycarbonate plate, and the window 60 has approximately the same shape as the upper and lower halves of the opening 42. Since it is slidably fitted into the frame 50, it can be easily opened and closed, and the above effects can be achieved smoothly.

"Effects of the Invention" As described above, in the present invention, a single polycarbonate plate is simply bent to form a lighting surface, and the carbonate plate is directly fixed between the roof body 20 and the base plate body 30. Therefore, the carbonate plate itself has a reinforcing effect as a bundle pillar, and as a result, a continuous opening surface can be formed without the lighting surface being divided by the bundle pillars or the like.

Furthermore, since one side of the carbonate plate is opened, a framework is attached to the edge of the opening, and a window portion that can be opened and closed is formed within the framework, the shape, area, and mounting position of the window frame space can be changed arbitrarily. It can be set freely, and as a result, the degree of freedom in design increases, and the lighting space can also function as a bay window or a greenhouse depending on the purpose.

Furthermore, the window frame is directly attached to the polycarbonate plate, and since the polycarbonate plate has impact resistance, it can be attached directly to the housing without intervening cushioning material, thereby reducing the number of parts. This leads to a reduction in weight burden and facilitates assembly.

Furthermore, according to the present invention, unlike conventional bay windows, the individual parts such as the casing, pillars, window frame, etc. do not have to be installed on the opening surface individually on site, and the polycarbonate plate on which the frame is assembled is integrated with the casing. If a fixed unit is first manufactured in a factory and the unit is directly attached to an outer frame fixed on the outer wall of a building, on-site work can be simplified and it can be easily installed in an existing building. .

It has various practical effects such as.
