Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an openable/closeable louver window that is installed in an opening of a building or the like.

[Prior art and problems to be solved by the invention] Conventionally, this type of louver window was often used for ventilation in kitchens, bathrooms, etc. due to its nature, but emphasis was also placed on architectural beauty. In today's architectural styles, there is an increasing desire to use louvered windows as decorative windows that also serve as ventilation in rooms such as living rooms and reception rooms in residential buildings due to their inherent aesthetic properties.

However, conventional louver windows have louver blades formed from daylighting plates such as glass plates, synthetic resin plates, or stainless steel plates, depending on the purpose.
It is known that the louver blades are formed from a light-shielding plate such as an aluminum plate, but in the former case, the louver blades are formed from a daylight plate, so even when the light is closed, light still gets in. There are disadvantages in that light cannot be blocked unless a light blocking member such as a shutter is separately provided, and security is poor, and in the case of the latter, conversely, it is blocked in a light blocking state, so it is not possible to block sunlight. Therefore, it has been proposed to use louver blades that combine a light-blocking plate and a light-letting plate, but in this case, in addition to the ventilation function, there are also functions such as shading blockage, light blocking, and good rain control. There has been a strong demand for louvered windows that have various functions such as excellent security.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a louver window that can eliminate these drawbacks. In a louver window configured such that a plurality of louver blades arranged in parallel can be integrally rotated about a support shaft as a fulcrum by operation of an opening/closing operation mechanism to switch between ventilation and blocking, the louver blades are used to control lighting. The plate and the light-shielding plate are integrally attached at a predetermined angle so as to expand downward into a mountain shape with the support shaft portion at the top, and adjacent louver blades are separated by operation of the opening/closing operation mechanism. To configure the structure so that it can change from an open position to a light-blocking closed state or a light-blocking state, in the ventilation open position, the light shielding plate is distributed so that it protrudes toward the outdoor side, and the daylighting plate protrudes toward the indoor side, and the adjacent louver blades are In the light shielding closed position, the lower end of the upper light shielding plate is brought into contact with the lower support shaft so as to overlap from the outdoor side, and in the light blocking position, the lower end of the upper light blocking plate is brought into contact with the lower support shaft from the indoor side. It is characterized by being brought into contact so as to

With this configuration, the present invention provides various functions necessary for a louver window.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a louver window in which the present invention is implemented, and the louver window 1 is installed in a window frame formed by upper and lower frames 2 and left and right vertical frames 2a. Reference numeral 3 denotes a louver blade constituting the louver window 1, and in this embodiment, the louver blade 3 includes a light shielding plate 4 formed of a light shielding member such as aluminum and a light blocking plate 4 formed of a light blocking member such as glass or synthetic resin. 5, a blade body is used which is bent at a substantially right angle. That is, the light shielding plate 4, which is formed into a long shape by appropriate means such as extrusion molding, has a fitting portion 4a for the support shaft 6 formed on its proximal edge side, and the light shielding plate 4 and the light shielding plate 4 are formed in a side view. A fitting groove 4b into which the daylighting plate 5 is fitted and fixed is formed so that the angle formed by the two sides is approximately a right angle, and the support shaft 6 and the daylighting plate 5 are respectively attached to the fitting portion 4a and the fitting groove 4b. The louver blades 3 are formed by this.

The louver blade 3 formed in this manner is rotatably supported by its support shaft 6 on the left and right vertical frames 2a, so that the louver blade 3 can be moved up and down so that the light blocking plate 4 is placed on the outdoor side and the daylighting plate 5 is placed on the indoor side. A plurality of them are arranged in parallel at predetermined intervals in the direction. The tip of the support shaft 6 rotatably supported by the left and right vertical frames 2a penetrates into the vertical frame 2a, but one end of the operating rod 9 is fixed to the tip of the support shaft 6 on either the left or right side. has been done. Each of the above operating rods 9 is fixed to a plurality of upper and lower louver blades 3, respectively.
The other end is connected and pivoted in a continuous manner via a connecting rod 8. On the other hand, the tip of the operating lever 7 whose base end side is integrally connected and fixed to any one of the operating levers 9 (the third one from the top in the embodiment) is bored in the vertical frame 2a. The louver blade 3 protrudes toward the indoor side through an elongated hole 7a, and by operating the protruding operating lever 7 up and down, the louver blade 3 is moved to the light shielding plate 4 with the support shaft 6 at the top, as shown in FIG. 3A. ,
From the intermediate ventilation open position in which the lighting plate 5 expands downward into a mountain shape and moves away, the tip of the light shielding plate 4 of the upper louver blade 3 is moved between adjacent louver blades 3 as shown in FIG. 3B. In a light-shielding closed position where the lower louver blade 3 overlaps the fitting part 4a of the lower louver blade 3 from the outdoor side and becomes substantially flush, or between adjacent louver blades 3 as shown in FIG. 3C, The tip of the light shielding plate 5 of the upper louver blade 3 contacts the fitting part 4a of the lower louver blade 3 so as to overlap from the indoor side, and is selectively transformed into a lighting blocking posture in which the light shielding plate 5 is substantially flush with the fitting part 4a of the lower louver blade 3. It is becoming possible to do this.

In addition, in the figure, 10 and 10a are rubber bodies for sealing,
11 is an insect net.

In the embodiment of the present invention configured as described above, in order to ventilate using the louver window 1, it is sufficient to set the operating lever 7 to the intermediate position, and thereby the louver blade 3 is moved to the fitting part 4a. The light shielding plate 4 and the daylighting plate 5 are expanded into a downwardly facing mountain shape with the louver blades 3 at the top in an open ventilation position, and the adjacent louver blades 3 are spaced apart from each other, from which ventilation is conducted.

On the other hand, to close the louver window 1, operate the operating lever 7 upward to set each louver blade 3 to a shading closed position in which the shading plate 4 is continuous approximately on the same surface with the support shaft 6 as the fulcrum. Of course, it is closed off with no sunlight. Moreover, in this state, the lighting plate 5
Although it is located on the indoor side, the light shielding plate 4 is in continuous contact with the fitting part 4a of the adjacent lower louver blade 3 in a state of overlapping from the outside, and is just like a shutter and is closed. Therefore, even if rainwater directly adheres to the light shielding plate 4, it will directly turn into water droplets and flow downward, preventing the problem of rainwater infiltrating into the indoor side from between the blades. The louver window 1 is made of
Not only is it crime-proof, but it can also be used as a rain door with excellent wind resistance.

In addition, in order to close the daylighting, the operation lever 7 is operated downward to set each louver blade 3 to the daylighting blocking position in which the daylighting plate 5 is continuous on an approximately flat surface. The continuous lighting plate 5 allows the louver window 1 to let in light while in the closed position. Moreover, in this case, since the daylighting plate 4 protrudes horizontally to the outside of the room, it functions as an eaves and effectively prevents direct sunlight and rain from directly hitting the side of the daylighting plate 5 in the closed position. Therefore, even if the upper daylighting plate 4 overlaps the fitting part 4a of the lower louver blade 3 from the indoor side, it can be made to have good rain protection.

Furthermore, this product has a mountain-shaped shape so that the bottom side expands when the ventilation is open, so if it is closed due to rain, the side with rain will face toward the indoor side. This makes it even better at keeping the rain out.

[Operations and Effects] In summary, the present invention is constructed as described above, and the opening can be changed from a ventilation open position to a light blocking state and a lighting It is possible to select and switch to any of the closed positions. Furthermore, when the louver blades are placed in a light-shielding closed state, the lower end of the louver blade contacts the support shaft of the adjacent lower louver window in an overlapping manner from the outside, creating a shutter structure. For this reason, the lighting board protrudes toward the indoor side, and even if rainwater directly adheres to the light shielding board, this rainwater will flow downwards and prevent it from entering the indoor side, making it a good way to shut off rain. In addition, the strength of the overlapping portion is increased, and the louver window can be used not only as a security feature but also as a storm door with excellent wind resistance.

On the other hand, when the sunlight is closed, the shading plate protrudes to the outside and acts as an eaves, which effectively prevents rain from penetrating into the support shaft along with the sunshade, and prevents the sunlight from entering the closed position. But it can be made into something that will hold up well in the rain.

Furthermore, both plates are assembled in a mountain shape so that the lower side expands when the ventilation is in the open position, so even if either of them is closed due to rain, the surface with rain will face indoors. without getting stuck,
Furthermore, it will be even better at stopping the rain.
