Description

[Detailed description of the invention] This invention relates to a blind in which the upper frame of the shutter of a step window is integrally provided.

The opening of a building is divided into upper and lower tiers, with the upper tier used as a small window, or transom, for lighting and ventilation, and the lower tier used as a regular window or shoji (shoji screen).

By the way, when installing shutters on this window, the upper and lower windows,
In the case of shutters that protect the shoji together with the shutters, the vertical dimensions of the shutters are long and large, which may cause problems in handling due to their strength, and in particular, the lighting and ventilation functions may be impaired.

Therefore, as shown in FIG. 1 as an example, conventionally, in order to provide a rain shutter only in the lower window opening, the shutter upper casing is constructed separately from the blind part of the step window, and is secured to the blind part with screws.

By the way, in this case, as the wind pressure acts repeatedly positive and negative,
There is a risk that the screws may become loose and the shutters may come off due to strong winds.

Also, the rain closure at the connection between the blind and the upper frame of the shutter was poor.
Screws appear on the surface and the appearance is not good.

In particular, a window frame is supported over its entire length by the building's frame, whereas a mume is supported at both ends by the building's frame or vertical frame. It is necessary to take reinforcement measures such as providing an overhanging hollow part on the interior side of the room or making the vertical wall thicker, which makes the appearance and installation of the room difficult, as well as making manufacturing and assembly difficult. There are many things.

Furthermore, when installing a shutter only in the lower window opening of a multi-tier window, the shutter frame is constructed separately, and when it is fixed to the sliding shoji window frame with screws, the shutter frame, which has been framed in a square shape in advance, is first assembled. Several workers lift and fix the shoji window frame and shutter frame while adjusting their relative positions, so the framed shutter frame is constructed to have sufficient rigidity to prevent it from twisting in an out-of-plane direction. Therefore, in the upper frame 10 of the shutter, a mounting part 14 including a pair of horizontal upper and lower leg pieces 12 and 13 extending toward the indoor side is provided on the shutter upper frame body 11 constituting the shutter sliding groove. The horizontal lower leg piece 13 is provided with a plurality of screw retaining portions 15, 16 at predetermined intervals, that is, sufficient intervals to prevent the shutter frame from twisting when the shutter frame is framed in a rectangular shape. Since the lower leg piece 13 is provided with an opening, the width of the lower leg piece 13 is inevitably quite large, and the upper leg piece 12 must also be made larger accordingly.
The mounting part 14 consisting of 3 has a projected width that is approximately the same as the main body part 11 forming the shutter sliding groove, and the projected size is very large as it is a blind with a shutter on the top of the shutter. Not only does this tend to deteriorate the appearance of the stepped window, but it is also uneconomical as it requires a large amount of material as a whole with an upper frame of the shutter.

Therefore, if such a shutter with an upper frame and no blind is integrally molded as it is, not only will it not be satisfactory in terms of appearance, but
It also becomes extremely uneconomical.

In particular, if the shutter has a separate structure, in order to correctly fix the upper frame of the shutter with screws, it must be fixed using something on the shutter body as a reference, and for this reason. In the conventional structure, the upwardly bent edge 12a of the horizontally facing upper leg piece 12 of the upper shutter 10' is connected to the upper corner edge 17a of the vertical vertical wall 17 on the vertical side outside the room.
It was fixed according to the

This is because the vertical vertical wall 17 on the vertical side outside the room is a flat surface and has no uneven stripes or the like that serve as a reference for attaching the upper frame 10 of the shutter.

Therefore, because the shutter upper frame 10 is fixed at a position considerably higher than the lower shoji sliding groove 18 of the blind 1 due to its installation, the lower rail board 19a of the upper screen door and the shutter upper frame 1 are fixed.
0 and the ceiling board 10a is almost eliminated, which impairs the drainage effect of rainwater on the top board 19. In addition, the rainwater on the upper frame 10 of the shutter is blown upward by the wind. If there is a strong wind, rainwater will often splash indoors from the blinds, and there is almost no difference in level between the rails of the shoji door or screen door and the top surface of the upper frame of the shutter. The problem was that the upper shoji and screen doors were difficult to remove.

As mentioned above, in the case of conventional shutters with an upper frame, the upper frame of the shutter is constructed separately and fixed with screws afterwards, which results in complicated installation, loosening of the mounting part because it is fixed with screws, and problems with rain closure. Not only is there a problem with poor appearance, poor appearance, and the inconvenience of reinforcing the blind and the resulting blind fitting, but there are also problems with the connection structure itself between the shutter upper frame and the blind, so it is necessary to consider only the installation of the shutter. Because the barrels are installed and fixed without openings, the drainage treatment effect for rainwater etc. is very poor, and rainwater easily splashes indoors through the openings.
Furthermore, no consideration was given to the difficulty of attaching and removing the upper shoji and screen doors.

This idea was devised to deal with the above-mentioned conventional problems, and its purpose was to eliminate the above-mentioned drawbacks caused by configuring the upper azusa of the shutter as a separate piece by integrally molding the upper azusa of the shutter and the no-mume. At the same time, we constructed a new integral connection structure between the upper frame of the shutter and the main body, and in accordance with this, we created an overhanging hollow part on the indoor side for the sole purpose of reinforcement, unlike conventional methods, and The overall strength of the shutter is made sufficient without any reinforcing measures such as making the vertical walls thicker, and the overall strength of the shutter is improved. In addition to solving the problem of rainwater blowing back, rainwater splashing from the upper shoji section caused by a decrease in the rainwater drainage function on the non-Japanese structure, and the difficulty of installing and removing the upper shoji and screen door, To provide a shutter with an upper frame and a blind with sufficient strength without deteriorating the overall shape of the blind with an upper frame.

The details will be explained below with reference to illustrated embodiments.

Each of the upper and lower tiers of the tiered window has a sliding shoji A on the inside and a screen door B on the outside.

The main body of Mume 1 forms a substantially rectangular hollow part 1a, and the upper board 1b and lower board 1C of the Mume body are provided with sliding shoji rails 2, 2.2', 2' and screen door rails, respectively. 3, 3' are provided protrudingly, and the upper substrate 1b and the lower substrate 1C
Each indoor side is configured as a shoji sliding part, and each outdoor side is configured as a screen door sliding part.

On the outdoor side of this non-Japanese body, there is an upper horizontal protruding piece 6a that is integrated with the lower end of the vertical wall plate 1d on the outdoor side of the non-Japanese body and projects to the outdoor side, and a lower board 1C of the non-Japanese body. It is connected to the hollow part 1a of the non-Japanese body by a lower horizontal protruding piece 6a' that is integrated and protrudes to the outside of the room, and a vertical connecting piece 6b that integrally connects both horizontal protruding pieces 5a and 5a' vertically. A reinforcing body part 6 having a C-shaped cross section and having a space part is formed integrally with the main body by protruding toward the outside of the room on the lower half side of the main body, and the hollow part 1a of the non-Japanese main body is effectively used as the main body. In addition, it is expanded in the direction of its expected width, and 1. It is a continuous reinforcement base for the shutter upper frame 4 that is formed integrally with this, and in addition, a gap is secured to prevent the shutter C from rubbing against or hitting the screen door B. ing.

Then, it is formed continuously and integrally with the upper horizontal protruding piece 6a of the reinforcing body part 6 to connect the ceiling board 4a of the shutter upper frame 4.

It is set up.

At this time, the horizontal protruding piece 6a is positioned down to approximately half the height of the outdoor end of the hollow part 1a of the blind main body, and is integrated with the horizontal protruding piece 6a to raise the shutter upper P. ! 4 ceiling board 4a
, and thereby the upper substrate 1b in the "non-Japanese body"
There is a difference in height between the outdoor side end of the frame and the ceiling substrate 4a of the shutter upper frame, which is approximately half the height of the outdoor side end of the non-Japanese body hollow part 1a, to improve the drainage effect. A shutter upper frame 4 is provided integrally with the non-Japanese body by forming a shape H, and a sliding groove 5 for the shutter C is formed on the lower surface of the shutter upper frame 4.

It should be noted that the vertical connection piece 6b of the reinforcing body portion 6 can also be configured to be used as a hanging piece 7 or the like that is a part of the upper frame of the shutter.

Further, reference numeral 8 is a screw holding part for fixing the shutter frame.

This idea consists of the above-mentioned configuration.In contrast to the conventional method, where simply screwing the separate upper frame of the shutter to the Mumihon body would put a burden on the Mumihon body, the outdoor side of the Mume body. By protruding the reinforcing body part 6 of the mold and the upper frame 4 of the shutter, the expected dimensions of the entire blind area are increased, so that it can sufficiently withstand strong lateral loads and prevent bending, etc. This ensures that the shutters are not blown away even if they are exposed to strong winds such as typhoons, providing strong support for the shutters.

In addition, an L-shaped reinforcement part 6 is provided between the blind main body and the shutter upper frame 4.
Since the two are connected together, the overall shape of the shutter is not deteriorated, and the strength of the shutter itself, especially the moment of inertia that resists lateral loads such as wind pressure, is maximized. It is increasing.

Also, there is a level difference H between the upper board 1b on which each rail of the upper sliding shoji door and screen door is provided and the ceiling board 4a of the shutter upper frame 4.
is made large, almost half the height of the outdoor end of the hollow part 1a of the main body, and this rainwater drainage step H, which has a large drop, quickly drains rainwater above the shutter onto the shutter. At the same time, rainwater on the upper frame of the shutter is drained from the step H.
1. Because the rainwater on the shutters will not be blown up onto the non-Japanese structure, and the rainwater will naturally flow down from the top surface. Splash from the open upper shoji section, which occurs with deterioration of the wastewater treatment function, does not occur.

In addition, since the connection part that supports the shutter upper frame 4 in a cantilever manner on the blind main body is structured to include the reinforcing body part 6, the connection part has a veneer-like or flat plate-like part 9 to a minimum. Therefore, the upper frame 4 of the shutter should be attached to the main body of the shutter while ensuring a distance to prevent the shutter C from rubbing against or touching the screen B. It has a strong and stable connected integral structure without any sagging, and has a strong holding effect of preventing the shutter from being blown away unless it warps itself even when the shutter is blown by strong winds such as a typhoon.

Furthermore, since the large step H is formed as described above, it is easy to install and remove the upper sliding shoji door and screen door.

In addition, since the non-japanese body and the upper frame of the shutter are integrated, it is possible to omit the manufacturing and assembly time required for conventional screw fixing, and there is no rain leakage, resulting in an excellent finished appearance.
