Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to bay windows, greenhouses, and other lighting space forming devices that bulge out from the building body to form daylighting spaces, and in particular, the invention relates to bay windows, greenhouses, and other daylighting space forming devices that bulge out from the building body to form daylighting spaces. The present invention relates to a lighting space forming device capable of forming a wide lighting surface that is not blocked.

``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 have been proposed, such as bay windows and greenhouses, which bulge outward to form a daylighting space, but these types of daylighting space forming devices generally consist of a roof frame fixed to the outside wall of the building on both sides of the opening. From the main plate frame and the main body part provided along the opening surface between the two frames, and to the main body part, in order to achieve a reinforcing function between the two frame bodies, bundles are perpendicularly arranged at arbitrary intervals. In many cases, a glass plate material that supports pillars and forms the lighting surface of the main body portion is surrounded by a window frame or the like, and the window frame is fitted between the bundled pillars.

"Problems to be Solved by the Invention" However, by attaching the pillars and window frames on the lighting surface of the main body, the number of things that obstruct the view increases, and the lighting surface becomes smaller and the lighting effect becomes less effective. This is not only unfavorable from an aesthetic point of view, but also increases the number of parts, which increases the weight of the bay window itself and complicates assembly.

In order to eliminate this drawback, in narrow bay windows such as triangular bay windows, the lighting surface was formed only by the window frame and the glass plate material attached to the window frame, without providing the bundle pillars. Attempts have been made, but 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 the dead weight of the roof frame applied from the top of the glass Therefore, in order to have enough load-bearing capacity to withstand the weight, the wall thickness must be increased accordingly, resulting in problems 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 a rigid body such as the roof frame.Generally, a window frame with cushioning material etc. interposed is first formed, and then the window frame is The frame must be attached 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 eliminates the presence of anything that obstructs the view, such as bundle columns or window frames, on the lighting surface of the main body sandwiched between the roof frame and the base plate frame, and is lightweight and has a small number of parts. An object of the present invention is to provide a lighting space forming device capable of forming a bay window or the like having a wide lighting area in a number of points.

"Means for Solving the Problems" In order to achieve the above-mentioned technical problems, the present invention projects almost horizontally toward the outdoors from the upper side of the rectangular building frame opening formed on the outer wall of the building. a first casing (generally functions as a roof body) provided thereon, and a second casing (generally functions as a ground plate body) protruded almost horizontally toward the outdoors from the lower side of the building frame opening; In order to partition the area where the first casing and the second casing face each other (which functions as a daylighting space) from outside, the bottom surface of the first casing is removed from one side of the opening in the building frame. extending along the side periphery and the periphery of the upper surface of the second casing, respectively, so as to reach the other side of the building frame opening;
a translucent polycarbonate plate having a substantially trapezoidal horizontal cross-sectional shape; the periphery of each of the casings is bent into a rectangular shape such that one side of the bent portion faces the polycarbonate plate; A pressing plate is disposed facing one surface of the bent portion, and the polycarbonate plate is fixed to the periphery of the housing with the polycarbonate plate sandwiched between the one surface of the bent portion and the pressing plate. We propose a lighting space forming device featuring the following features.

In this case, there is no particular mention of the means for fixing the polycarbonate plate to the periphery of the casing, but since the casing is generally made of metal and the polycarbonate plate is made of resin, adhesives or other materials may be used to fix the two. Fixing with screws or rivets has the advantage of being simpler and easier to disassemble and reassemble than using screws. In this case, it is preferable to fix the polycarbonate plate using a clamping member such as a screw rivet, with the polycarbonate plate sandwiched between one surface of the bent portion and a pressing plate located on the back side thereof.

"Operation" According to this technical means, since a translucent polycarbonate plate bent along the periphery of the housing is placed in the area that functions as a lighting space sandwiched between the upper and lower housings, the opening The entire area can be illuminated without being obstructed by pillars, window frames, etc.
Moreover, the polycarbonate material has impact resistance strength 400 times that of glass, and the polycarbonate plate is not kept hollow, but is directly fixed to one surface of the bent part provided on the periphery of the pair of upper and lower cases. Therefore, the polycarbonate board itself can have the function of a bundling post that supports the pair of upper and lower housings, and this makes it possible to form a wide trapezoidal bay window without providing a bundling post or the like. .

However, when the front opening is applied to a wide trapezoidal bay window, the trapezoidal side parts of the polycarbonate plate are located on both sides of the bay window. It can be supported more firmly, and as a result, the wide polycarbonate plate will not sway due to vibrations or wind, and it can be supported more firmly.

In addition, as mentioned above, the polycarbonate plate has 400 times more impact resistance than glass, so it can be attached directly to one side of the bent part formed on the periphery of the housing without intervening a window frame or cushion material. This makes it possible to reduce the number of parts, reduce the weight burden, and facilitate assembly.

"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.
