Description

The present invention relates to a ventilation louver attached to a window.

The doors that are retrofitted to the windows may not be installed with shutters or windows with grids / shutters due to the balance between the screen doors and the shutters / lattices / shutters, and can be easily installed in high-rise areas such as apartments. There are problems, such as not.

However, in the gallery provided with a portion where the blown-up rainwater collides and temporarily stays as described in Patent Documents 1 and 2 above, since the depth dimension of the gallery itself becomes longer, the rain door, the grid, For windows with shutters, the space between the screen doors is narrow and a glass window can be installed on the indoor side of the screen door, but only the size corresponding to the thickness of the glass window frame can be taken, and there is an extremely narrow size constraint on the outside of the room. Therefore, it is difficult to install on existing windows with shutters and lattices.

The problem to be solved is that the dimensions are narrow both inside and outside the room, so the depth of the louver is half that of the louver attached at the same angle as the louver attached to the window without a shutter on the outside of the screen door. In the following, when comparing these two types, the longer depth of the galleries Figure 1 shows that rainwater blows up on the top of the louver due to the wind force during wind and rain, but the slope of the louver is also long, and the momentum of rainwater is near the top of the louver. The rainwater is less likely to enter the indoor side from the upper end, and it is less than half the depth of the garari. In Fig. 2, the rainwater blows up to the upper end of the louver with the force of wind and rain. Fig. 2 shows that the depth of the louver is shorter, so the louver is not very effective in preventing rainwater from entering. If that, the effect of preventing Furikomi of rainwater can be increased, ventilation quantity is a problem that extremely reduced.

In FIG. 3 in which a backflow prevention plate is provided at the upper end of the louver, the depth of the louver is short, so the gap between the top and bottom of the louver is narrowed, the number of louvers is doubled, and the ventilation area is reduced by the height of the backflow prevention plate. If the amount is reduced and the height of the backflow prevention plate is lowered, the ventilation area is increased and the ventilation volume is increased, but there is a problem that rainwater falls when the rainfall is large.

An object of the present invention is to provide a gallery having a thin depth that prevents rainwater from being blown into a room even during heavy wind and rain.

If the depth of the louver is shortened as shown in FIG. 2, the purpose of the louver to prevent rainwater from entering is weakened. If a backflow prevention plate is provided at the upper end of the louver in FIG. 3, the distance between the louvers is narrow and the ventilation area is reduced. Therefore, the backflow prevention plate of the louver is made smaller in shape by dividing the backflow prevention plate into a plurality of shapes, and the backflow prevention plate shown in FIG. 4 divided into the vicinity of the center and the upper end of the louver is described as an example. In the center of the depth dimension of the louver, the upper end of the louver is shaped like a two-tiered backflow prevention plate that is curved in an inverted shape. By reversing 180 degrees with the backflow prevention plate near the center, the reversed rainwater flow collides with the rainwater that blows up from the bottom of the louver surface and backflows, and the force is offset and a small backflow prevention plate near the center prevents it. In FIG. 5, when the amount of rain increases, some rainwater that has passed over the backflow prevention plate in the central part flows back to the upper end of the louver. Even the small backflow prevention plate at the upper end can adequately prevent the difference between the amount of rainwater that falls between the lower side of the louver and the vicinity of the center, and the amount of rainwater that falls between the center of the louver and the upper end of the louver. The upper side is so small that it is not comparable. There is also a louver above the louver currently being described, and the amount of rainwater that falls down is a shadow of the eaves of the upper louver. It is offset by the rainwater blown up and the flow reversed 180 degrees by the backflow prevention plate near the center, and the curved portion that becomes the height of the backflow prevention plate is suppressed to about 6 mm in diameter in order to prevent rainwater by the multiple backflow prevention plates. As a result, the ventilation area between the louvers is widened, the amount of ventilation is secured while preventing rainwater from entering, and the depth of the entire louver at an installation angle of about 48 to 60 degrees. FIG. 11-A is characterized in that it can be thinned from about 20 millimeters to 30 millimeters.

The depth of the louver can be shortened by the louver with multiple layers of rainwater backflow prevention plates, so it can be installed on the outside of the window screen with a grid, shutters, shutters, and indoors from the screen door. be able to.

A view of the louver from the side when there are no dimensional restrictions on the outside of the screen door (the left side of the figure is the outdoor side and the right side is the indoor side). Because of the long distance, rainwater does not easily enter the room. Due to dimensional restrictions on the mounting position of the louver, a view of the louver from the side with a louver inclination distance of half or less compared to FIG. 1 (the left side in the figure is the outdoor side and the right side is the indoor side). Because it is short, the speed of rainwater does not decrease so much, and rainwater easily enters the room. The view of the louver from the side (the left side is the outdoor side and the right side is the indoor side). The upper part of the louver is curved to reverse the direction of rainwater flow, but the distance between the backflow prevention plate and the upper louver Is narrow and there is little ventilation. In the view of the louver from the side (the left side of the figure is the outdoor side and the right side is the indoor side), the backflow prevention plate is lowered and divided into multiple parts to increase the ventilation area. FIG. 5 is a view of the louver from the side (the left side of the figure is the outdoor side and the right side is the indoor side), and the wind and rain are stronger than FIG. 4. A view of the louver from the side (the left side in the figure is the outdoor side and the right side is the indoor side), and is a view of the louver provided with three backflow prevention plates. The figure which looked at the window (the left side of the figure is the indoor side, the right side is the outdoor side), and shows the installation position of the louver window incorporating the louver with the backflow prevention plate. The figure which looked at the window (the left side of a figure is an indoor side and the right side is an outdoor side), and is a figure showing the position at the time of use of a louver window. FIG. 5 is a perspective view of a window (the left side in the figure is the indoor side and the right side is the outdoor side), and the position configuration of the rail and each window when a rail dedicated to the louver window is installed. FIG. 3 is a perspective view of a window (the left side in the figure is the indoor side and the right side is the outdoor side), and the position used as the louver window on the rail dedicated to the louver window. Side view of the glazing window (the left side of the figure is the outdoor side and the right side is the indoor side)

An existing sliding sash window, the glass window consists of the indoor side, outdoor side, and screen door. There are two glass window rails on the window frame of the sash window, both when the glass window is closed and open, and the glass window on the indoor side usually moves to the left and right when opening and closing. The glass window on the outdoor side usually does not move from the place, so the playing rail has the same dimensions as the frame of the glass window, and only the width of the glass window is about half of the glass window. By incorporating it on the glass window rail so that it moves smoothly, the thickness of the glass window can be as small as a few centimeters, and the glass window can be locked as before. The room can be ventilated without being affected by the weather from spring to rainy season, summer to autumn, and it does not wet the room due to sudden sunsets, etc. It is an invention.

The size of the glass window frame is the same as that of the glass window frame, but the rail window is also provided with a window frame dedicated to the same shape, but only the horizontal dimension of the window window frame is about half that of the glass window frame. It is not possible to wet the room even in a sudden rain while sleeping, by attaching the glass window that incorporates the glass window rail directly inside the screen door, or the glass window rail on the indoor side in front of it. Ventilation can be secured, and the window can be moved sideways so that objects can be put in and out and children can go in and out, and it can be attached to the glass window rail on the innermost side of the glass window. At times, it is safe to close the windows as usual, and even on the higher floors of an apartment, it can be attached to the glass window rails of existing windows from the indoor side, so the safety during installation is also high.

In hospitals and other nursing homes, since residents are less likely to adapt to temperature changes, staff are rushed to prevent secondary disasters such as falls caused by wet corridors, etc. However, by attaching the present invention, you can concentrate on taking care of tenants without having to panic, and in places where ventilation is always necessary, such as in warehouses and barns, you can work regardless of sudden changes in the weather. it can.

The sliding window sash window, glass window indoors, outside, glazed windows where rain does not fall, and a new window frame composed of screen doors can be newly opened, and the glass window of the window can be opened and closed as a normal window In addition, we will propose a sliding sash window that adds a new rail for window doors that does not allow rain to enter and exit from the window and for indoor ventilation.
