Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a corner mullion of a bay window in which the corner of the mullion visible from the outside is recessed to a relatively large extent.

[Conventional technology]

In a bay window, a mullion is generally attached to the corner of the overhang to secure the glass or shoji, but from the outside, the mullion appears as the ridgeline of the bay window, giving a relatively strong impression. Moreover, depending on the external shape of the mullion, the image of a bay window can change dramatically, so recently, the corners of mullions have been recessed relatively greatly to achieve this effect.

[Problem that the invention attempts to solve]

However, as mentioned above, if the corner part is relatively large and recessed, the connection with other parts will generally be poor.
This also affects the stability and strength of the mullioned ends, causing water leakage.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a corner mullion of a bay window that solves the above-mentioned problems.

[Means for solving problems]

In order to achieve the above object, the present invention provides a bay window structure in which the corners of the mullion are relatively largely recessed and the corner mullions formed hollow are attached to the corners of the bay window overhang. It is characterized in that a closing cap is attached to the lowermost end of the closing cap, and a flat plate portion having substantially the same shape as the concave shape of the corner portion is extended from the closing cap.

[Effect]

There are strong design requirements for the recessed shape, and various shapes such as a fan shape and a triangle are often taken. The contour of the lowest end of the mullion also differs depending on this difference in form, but in the present invention, the shapes of the closing cap and the flat plate portion are determined according to the contour and the concave shape. If the concave shape is fan-shaped, the surface of the closed cap that contacts the corner portion will be arc-shaped, and the flat plate portion will be fan-shaped. In the case of a triangle, the surface is straight and the flat plate part is triangular.

Due to the presence of this flat plate portion, the lower frames and lower frames that are adjacent to each other with the mullion in between can be straightly butted together at the corner portions without any traces being cut along the way. As a result, the mounting surface to which other components are attached on the lower frame and lower stile side, including the flat plate part, has a flat configuration including the corner part, and in this invention, the mounting member is formed to match the recessed shape. There's no need to do that. Therefore, it is possible to obtain the same bonding performance as that of the conventional corner shape, and to reliably eliminate the factors that cause water leakage. On the other hand, on the mullion side,
Since one side of the closed cap comes in close contact with the corner portion and is strongly reinforced, it is easy to ensure watertightness.

〔Example〕

Examples will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the embodiment is applied to a square bay window that is commonly used. This bay window 1 has sliding shoji 2 on the front,
Fitted shoji 3, 3 are erected on both sides, and these shoji 2, 3 are directly or indirectly supported by corner mullions 5, 5 attached to the corners of the bay window projecting part 4.

Usually, in this type of bay window, the corner mullion is formed hollow by aluminum extrusion molding, and its external shape is often made to match the corner shape of the bay window overhang. For example, when the corners of the bay window overhang are made at right angles as in the illustrated example, the window is generally formed into a square shape.

However, when looking at a bay window from the outside, the mullions appear as the ridgeline of the bay window, so they have a greater influence on the appearance of the bay window than the frame shape or opening/closing pattern. Therefore, although matching the mullions to the corner shapes as described above provides relatively good matching between members, on the other hand, it is subject to design constraints. As a result, the exterior becomes monotonous, and there is a risk that the bay window will look the same no matter what.

Recently, there has been a demand for more innovative products, and in order to meet this demand, the corner portions are being recessed to a relatively large extent without being restricted by corner shapes. The illustrated example is one in which the corner portion 5a is scooped out into a fan shape, but generally speaking, when the corner portion 5a is cut out in this way, the bay window overhang portion 4
The ground of the same shape as the recessed shape is exposed at the corner, which makes it look bad. Therefore, conventionally, the draining board 6 attached to the side surface of the bay window overhang part 4 was bent along the upper surface, and its end was extended to the lower end of the mullion 5 to cover the exposed surface and improve the appearance. However, with this solution, it is generally difficult to ensure watertightness between the mullion 5 and the drain plate 6, and this has also been a cause of water leakage.

This invention solves the above problems,
As a solution to this problem, a third
The closure cap 7 seen in the figure is installed. The closing cap 7 is designed to ensure watertightness between the corner mullion 5 and other members, specifically the draining plate 6, and includes at least a rising piece 7a and a flat plate portion 7b. The rising piece 7a is mainly designed to maintain watertightness with the mullion 5 facing the outside, and in the illustrated example, since the corner portion 5a of the mullion 5 is curved in an arc shape, the rising piece 7a also has a corner portion 5a. It is formed to be curved along the inner wall of the corner portion 5a, and both ends thereof are further bent so as to follow the inner walls on both sides of the corner portion 5a.

On the other hand, the flat plate part 7b is provided extending horizontally from the lower end of the rising piece 7a, and its planar shape is the same as the concave shape of the corner part 5a, that is, the corner shape of the bay window overhang part 4. It is shaped like a fan. Therefore, it is possible to join at the corner position without bending the draining plate 6 as in the conventional case. Further, a vertical piece 7c is formed on the lower surface of the flat plate portion 7b, and serves as a mounting position for the draining plate 6. This vertical piece 7c is arranged at a position slightly recessed from the edge of the flat plate part 7b, and is turned at an angle of 90 degrees from the tip of the flat plate part 7b. Therefore, during installation, a space partitioned by the vertical piece 7c is created between the flat plate part 7b and the bay window extension part 4, and this space is used as a groove for filling the sealing material. Normally, joints are filled with sealant to make them watertight.
In the present invention, the upper part of the drain plate 6 is bent into an L-shape, the bent part is fitted into the space, and the space surrounded by the bent part and the flat plate part 7b is filled with a sealing material 8 from the outside to make it watertight. .

Watertightness is achieved between the drain plate 6 as described above, but it is also necessary to ensure watertightness between it and the corner portion 5a. In the embodiment, a groove 7d of a constant width is formed along the intersection line where the rising piece 7a and the flat plate part 7b intersect at right angles, and the corner part 5a
After cutting up the lowest end of the groove 7d and attaching the closing cap 7 to the lowest end of the mullion 5 as shown in Fig. 4,
The groove 7d is filled with a sealing material 9 to ensure watertightness between the two. Any method may be used for attachment, but in this embodiment, a mounting piece 7e is provided along the indoor corner of the closing cap 7, a corner of the mullion 5 is applied to the mounting piece 7e, and both are screwed together. stop 10,
I try to... Furthermore, a cutout 7f is provided at both ends of the flat plate portion 7b that intersects with the rising piece 7a, and the upper and lower sealing members 8 and 9 are connected using the cutout groove 7f. This is to prevent water leakage, which is relatively easy to occur at the seal end.

Although the above embodiment is an example in which the bay window overhang 4 is not provided with a drain width, the present invention provides a drain of a constant width along the line of the bay window overhang 4 as shown in FIGS. 5 and 6. It can also be applied to cases where a width is provided.
In this embodiment, the front and side draining plates 6, 6 are attached to the upper surface of the bay window bulge 4 in the same way as in the conventional case, and the end thereof is a vertical piece of the closing cap 7 attached to the lowest end of the mullion 5. It is joined using 7c. Since the joining means is the same as in the previous embodiment and the other configurations are also the same as in the previous embodiment, only the reference numerals are shown in the drawings and the explanation will be omitted.

[Effect of idea]

As explained above, according to the present invention, even if the corners of the mullion are relatively large recessed, the closed cap allows the mullion to connect with other members and prevent water leakage. The degree of freedom increases and it becomes possible to provide innovative bay windows.
