Description

The present invention relates to a movable louver provided on a window of a building.

Movable louvers of intermediate level or lower for residential use may be seen at a rate of about 1 in 100. You can also buy it online. Almost made of aluminum, it is the color of so-called aluminum sash, and the color of flowers, plants, sky, water, etc. is not seen, and it is surrounded by a solid square frame, and it has a neat shape. I can't see anything.

High-end products such as electric, remote control, full-color, crime prevention, and long louvers are on the market, but they are expensive and generally not widely used.
There are a huge number of houses and buildings, so windows are also important. Window louvers are effective for saving cooling power by saving energy and can be expected to increase in the future, but the price is still high. Moreover, since the amount of money per house is small, it seems that there are many difficulties in expanding the business.

Therefore, we hope that simple, easy-to-use, inexpensive, and paintable products will be proposed and spread using inexpensive commercial products. Depending on how it spreads, I think it will be prepared from the design stage of the housing manufacturer.

Patent 3934670 Louver and fittings using it

JP 2017-203345 Blind equipment and fittings

The problem to be solved is that it has a complicated structure and requires a high cost.

The main features of the present invention are that the required functions are narrowed down, the number of members is reduced, and ready-made products are frequently used.

First of all, the movable louver does not have shielding performance. Since there is a window with excellent airtightness and watertightness inside, I think that it is only necessary to secure light shielding and ventilation.
The first feature users want from louvers is that they want to get rid of the hot sun, and they also want the ability to blindfold.
Also, even if there is no remote control or electric drive, there seems to be no strong demand because it is not operated frequently.

As for the mounting method, if it can be connected to the existing window member, the cost is easily low, and if it can be replaced with the existing shutter, there is almost no treatment to the existing one.
Also, if the shutter shutter is currently used, some users may want to install a movable louver like a surface grid on the outside.

In terms of reducing the number of parts, the hinge shaft for rotating the blades of the louver is a tapping screw, and the member on the blade side of the hinge is a blade end bent at a right angle.

For ready-made products, the blade material of the louver is colored steel plate, the surrounding frame and interlocking frame are small size lightweight channel steel, strip steel for joints, rope as a substitute for washers, and ready-made electric power for attachment parts to existing fittings. Anti-corrosion paint, washer for friction tightening part, steel wire for frame close contact holder, shutter door wheel, center-fold screw tightening for locking under shutter, countersunk screw, countersunk tapping screw, pan head tapping screw, each can be obtained immediately It's all about things.

The main parts after processing are louver blades, vertical frames, upper frames, lower frames, interlocking frames, and joining members.

The louver blades are made by cutting colored steel plates to the required dimensions and processing them into a flat oval cross-section cylinder with layers. A paint is placed in the overlapped part, and the adhesive strength is expected after it is cured. No joining screws or rivets are used. The smooth surface makes painting easy.

The corner joints of the vertical frame, upper frame, and lower frame are cut at 45 degrees, and the corner joint members are fitted and connected, screw holes are made from the edges, internal screw taps are applied, and tightened with countersunk screws. For the corner joint member, apply a thick zinc rust preventive paint and fit it in the undried state to make it adhere.

Drill holes for M3 hinges in rows at intervals of about 50 mm on the vertical frame and interlocking frame. Use countersunk tapping screws for the hinge shaft.

In most cases, adjust the interval of about 50 mm between the vertical frame and the interlocking frame. This is because it does not make odd-sized louver blades. This also contributes to simplicity. The interval can be obtained by calculating, but since it is difficult to mark, adjust the tension of the elastic measure to realize the reading of millimeters in 1 mm units, preferably in 10 mm units.

The movable louver of the present invention has the advantages of significantly reducing costs, contributing to the prevention of global warming, and delivering comfort and satisfaction to many users.

FIG. 1 is an explanatory view of a movable louver of a small window. In the explanatory drawings and the like of the present invention, the symbols / numbers are common to all the drawings, and the same symbols / numbers are not assigned to different parts or the like. In all drawings, "specified number and _" are added to the beginning of drawing names, part names, and annotations, making it easy to identify. If there is a "_" after the number, the figure name and description are displayed after the "_". It may be pointed by the number alone, or it may be used together with the explanation of "_". FIG. 2 is a partial cross-sectional view taken along the line in FIG. FIG. 3 is a detailed view of the 30_corner joint material in FIG. FIG. 4 is an explanatory view of louver blades and hinge positions. FIG. 5 shows Example 1 and is an example of a kitchen window-sized surface grid louver. FIG. 6 shows a second embodiment, which is an example of a shutter of a sweep window. FIG. 7 is an explanatory view of a cross section of a louver blade.

FIG. 11 is an explanatory diagram for strengthening the frame material.

Examples are a surface grid example and a shutter example, and explanations will be given with (0029) and (0032) far ahead. Here, the difference between the two examples will be explained in advance.
First, assume the surface grid type of movable louver (not including mounting parts). Then, the shutter type of the movable louver is the one with the additional lower frame and additional upper frame, and the door roller and other small parts attached.
The shutter type has a restriction that it cannot be put in the door pocket unless the thickness when it is stored in the door pocket is about 22 mm or less, but the surface grid type does not have that.
In both types, since there are almost movable screen doors on the inside, the distance from the screen door to the vertical frame is about 35 mm due to the rotation of the louver blades.

Next, the elements common to the two examples will be explained using the small window example in Fig. 1, Fig. 2, Fig. 3, and Fig. 4.
This is because it is easy to explain in the case of a small and cohesive figure.
The blades of the 01_louver are tightened to the 09_interlocking frame on the indoor side and to the 05_vertical frame on the external side.
09_ For the interlocking frame, the connection is completed there.
The 05_vertical frame is rectangular through the 06_upper and lower frames and the 30_corner joint.
06_ The role of the upper and lower frames is 05_ positioning of the vertical frame and suppression of warpage. Therefore, it is necessary to assemble on a horizontal surface plate.

The material of 05_vertical frame, 06_upper and lower frame, and 09_interlocking frame is lightweight channel steel 19 * 10 * 1.0, which is galvanized. It is a mass-produced ready-made product with a medium aggregate under the light iron wall. Zinc paint is rust-proofed at the cut and perforated areas, and finish coating is applied. In Fig. 2, the cross section at the cut position shown in Fig. 1 is shown.
The 30_corner joint material is shown in Fig. 3. In Fig. 3, it is said that there is a 31_hole tap, but after fitting it into the 05_vertical frame and 06_upper and lower frames, make a hole together and cut the tap there. It cuts from mass-produced steel strips with the minimum number of cuts, and chamfers the interference part with the fillet of lightweight channel steel. Zinc paint is rust-proofed on the entire front and back, and finish coating is applied. Requires 35_493 hole M3.5 for 30_corner joint material. All four are not the same.

The 05_vertical frame and 09_interlocking frame have a row of M2.5 holes at intervals of approximately 50 mm. Positioning will proceed based on the features shown in Fig. 4. As shown in the 101_H-H cross section in Fig. 10, 03, 04 and 493 penetrate, and beyond that, the 02_ blade end bending of the 01_ louver blade also penetrates.
02_ Make a hole in M3 for bending the blade end.

Tap M3 in the holes of 05_vertical frame and 09_interlocking frame. 03 and 04 use the countersunk tapping screw M3. These are the fulcrum hinge and the interlocking hinge, respectively. Since the pitch is different from the M3 tap screw in the hole, 03 and 04 can be tightened respectively.

01_ Make a hole for M3 in 02 of the louver blade. 03, 04 and 493 just fit in the hole, and smooth rotation can be achieved. (03, 04 and 493 do not rotate)
From the tips of the 493 screws at the top and bottom of the interlocking frame, pass a washer with an M2.8 hole in the center of a steel plate of approximately 3.5 * 30 * 1.0, as shown by 88_ in Fig. 8. .. The holes for the four countersunk tapping screws 493, which are combined on the left and right, are M3, which is 0.5 mm larger than the others.

These four 493s are tightened in the 09_interlocking frame part and 02_blade end bending without screws, and only 088_ works, so tighten the 104_gap filling washer in Fig. 10 to make it moderate. It will realize the movement restraint of the blade with a great frictional force. It also functions as a positioning for 09.
For the countersunk heads of 03, 04 and 493, pre-drill the holes of 06 and 09. The countersunk head is almost invisible due to the finish painting. The form is so refreshing that you don't even notice what supports the wings. It is also effective in crime prevention if you cannot find a screw that can be removed.

The cross-sectional shape of the 01_louver blade is shown in Fig. 7, and the partial details are shown in Fig. 8.
This closes the explanation of the example with the small window of the movable louver.
To change the rotation of the blade, simply grab the end of the blade with your fingers and raise or lower it. Due to variations in processing accuracy, moderate resistance naturally occurs, and it does not start moving on its own.
In this example, the support hinge occupies the center of the shape of the blade, and the gravitational eccentric moment is almost zero, so it can be moved lightly at any rotation angle of the blade. See the description in 43_ and 44_ in Figure 4.

The 51_ display in Fig. 5 is a front view of the surface grid type. This outer width is 1798 mm and the outer height is 649 mm. The fineness of the numbers has no particular meaning, but it is the size often found in kitchen windows.
53 is an existing window mounting part, but if it is displayed at the same scale, it is difficult to see, so small parts etc. are explained using the figure of the movable louver for another small window.
01, 05, 06 correspond to the part names in other figures.

The hinge position of 51_ display in Fig. 5 is determined in consideration of the contents of 47_ and 48_ in Fig. 4. It is a little heavy, but if the number of blade stages is 12, there is no problem.
In the installation explanatory view at 52_ in FIG. 5, 56_ is tightened at 57_ in all four places on the outer frame of the existing window, and 59_ and the lower side are placed at two places on the upper side of the assembled movable louver. Tighten 591_ in two places.
The materials of 56_, 59_, and 591_ are made of rust-preventive zinc paint and finish-painted steel plate with a thickness of about 1 mm. The existing window frame is coated with anti-electrolytic paint and a resin washer is applied. Tighten the tapping screw using it, and then apply paint to prevent electrolytic corrosion.

Here is the installation of the movable louver.
562_ Temporary hanging tapping screw is displayed, but it is temporarily hooked on the notch of 593_ attached to 56_. Then, after aligning the holes, tighten the 58_ screw.
Zinc paint is rust-proofed on steel parts, and finish paint is applied on top of it.

The 61_ display in Fig. 6 is a front view of the shutter type. This outer width is 898 mm and the outer height is 1799 mm. The fineness of the numbers has no particular meaning, but it is the size often found in sweep-out windows.
The parts that are increasing from the small window example in Fig. 1 are 65_additional lower frame for shutters, 66_additional upper frame for shutters, 67_lower contact holding hardware lower, 68_lower contact holding hardware upper, 69_upper Adhesion holding hardware for lower, 691_ upper contact holding hardware for upper, 692_ door roller.

65_Additional lower frame for shutters secures the width for mounting the door roller. 06_ The lower frame is lapped and joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attached plate is on the back side.)
66_Additional upper frame for shutters is for inserting movable louvers in the shutter upper groove of the existing fitting upper frame with an appropriate gap. 06_ The upper frame is lap-joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attachment is on the back side of the board.)
Cut the 692_door car over both the 06_lower frame and the additional lower frame for the 65_shado, and install the door car in the cut space. Make a hole in the steel plate with the specified position in advance for fixing the door roller, and tighten it with the countersunk tapping screw.

67_Lower contact holding hardware lower, 68_Lower contact holding hardware upper, 69_Upper contact holding hardware lower, 691_Upper contact holding hardware upper is approximately 22 mm thick when the shutter is stored in the door pocket. It is for securing.
It is made by bending a steel wire, and it is a simple one that uses 03_ as a hinge and hangs it on 04_ with a finger. There is room for improvement to another type, but it will be practical.
Cut approximately 15 * 25 holes in the 09_interlocking frame to make space for handling.

Zinc rust preventive paint is applied to steel parts, and finish paint is applied on top of it.
The explanation of Example 2 is closed here.

Here is a list of related matters.
Fig. 11 shows an example of cross-section enhancement. Not only steel products but also ready-made aluminum products are available on the market, so you can make them stronger or lighter in terms of cost. As for painting, there are some that can be expected to be durable, so you can choose the color you want.

When using all-aluminum products, it is best to use aluminum for joining materials and tightening screws to prevent electrolytic corrosion, and it is necessary to increase the size.

If the horizontal length exceeds 1200 mm as in Example 1, the deflection of the 01_louver blade's own weight is a concern, so the louver is processed upward. Test how much load causes plastic deformation, adjust the conditions, and finish one by multiple operations. By making the upper side of the blade, which is the extension side of this mukuri processing, the overlapping part, it is possible to prevent the gap between the overlapping parts from opening.

01_The color steel plate, which is the material of the louver blade, is made by baking polyester paint on the original plating plate specified by JIS G 3322. As a color steel plate, it is the third grade from the cheapest to the top and is usually mass-marketed. The manufacturer's red rust warranty is usually 11 years. If the air conditions are good, the durability will be much longer. Even after many years, the cross section of the member of the present invention can be easily repainted. If you like the color of the material, you can leave it as it is. The cut surface of the material is likely to rust and will not rust. This is because the aluminum-zinc alloy takes in rust at an early stage.

As for paints, most of the water-based paints can be enjoyed because the popular colors are sold in large quantities from ready-made small cans. The roller brush finishes almost evenly.

To prevent electrolytic corrosion on the existing aluminum frame, apply anti-corrosion paint to the holes and screws before passing the galvanized tapping screws through the holes and then tighten them. A round head seems to be good for the screw head. Apply anticorrosion paint to the screw heads both inside and outside. For washers, apply anticorrosion paint both inside and outside. Avoid anti-corrosion type plastic washers as they are likely to deteriorate quickly with UV rays. As an anticorrosion paint, an oil-based ready-made mass-market paint seems to be good.

Since the cross section of the louver blade of the present invention is tubular, a reinforcing material can be inserted into the hollow part. By making a rectangular cross section of about 4 * 12 with colored steel plate and inserting it over the entire length, it takes time and effort to improve strength and bending performance, but it can be easily realized. There seems to be a demand for crime prevention to lock the door while allowing ventilation at night. It seems that this can also be met.

It seems that a material such as a flat belt of a machine can be inserted into the hollow part of the blade. Since it cannot be easily cut with a clipper, etc., it seems that security performance can be expected.

The strength of the colored steel plate and the screw is almost confirmed. For the best strength, for 03 and 04, set the hole in the frame to M3.5 and place a washer inside the blade, as in 493_.

In the present invention, the front view is consciously displayed as the outside side, but it is possible to replace the inside and outside without any trouble. If you can't see the interlocking frame from the outside, it's usually evaluated as smart, but if you have an opinion that you prefer not, you can respond.

Not only used for windows, but also for outer walls, it blocks sunlight, prevents the temperature rise of the walls, copes with radiant heat, reduces the amount of air conditioning operation, and contributes to the suppression of global warming.
In addition, by attaching a sheet-shaped photovoltaic power generation material to about 85% of the surface of the louver blade, it is possible to use it as a heat shield effect for the outer wall and as a power generation resource.
The movable louver of the present invention is made into a suitable size, a Z-axis rotation mechanism is added, and electrification, remote control, and automatic tracking are achieved, which contributes to the improvement of the efficiency of photovoltaic power generation on the wall surface.
The automatic tracking of the previous line is used to concentrate the reflected light on a specific location, and the power generation material is installed in the concentrated location to improve the power generation efficiency. It can also be used as a shade measure.

Since it corresponds in each figure, it is omitted.

The present invention relates to a movable louver provided on a window of a building.

Movable louvers of intermediate level or lower for residential use may be seen at a rate of about 1 in 100. You can also buy it online. Almost made of aluminum, it is the color of so-called aluminum sash, and the color of flowers, plants, sky, water, etc. is not seen, and it is surrounded by a solid square frame, and it has a neat shape. I can't see anything.

High-end products such as electric, remote control, full-color, crime prevention, and long louvers are on the market, but they are expensive and generally not widely used.
There are a huge number of houses and buildings, so windows are also important. Window louvers are effective for saving cooling power by saving energy and can be expected to increase in the future, but the price is still high. Moreover, since the amount of money per house is small, it seems that there are many difficulties in expanding the business.

Therefore, we hope that simple, easy-to-use, inexpensive, and paintable products will be proposed and spread using inexpensive commercial products. Depending on how it spreads, I think it will be prepared from the design stage of the housing manufacturer.

For ready-made products, the blade material of the louver is colored steel plate, the surrounding frame and interlocking frame are small size lightweight channel steel, strip steel for joints, rope as a substitute for washers, and ready-made electric power for attachment parts to existing fittings. Anti-corrosion paint, washer for friction tightening part, steel wire for frame close contact holder, shutter door wheel, center-fold screw tightening for locking under shutter, countersunk screw, countersunk tapping screw, pan head tapping screw, each can be obtained immediately It's all about things.

Examples are a surface grid example and a shutter example, and explanations will be given with (0028) and (0031) far ahead. Here, the difference between the two examples will be explained in advance.
First, assume the surface grid type of movable louver (not including mounting parts). Then, the shutter type of the movable louver is the one with the additional lower frame and additional upper frame, and the door roller and other small parts attached.
The shutter type has a restriction that it cannot be put in the door pocket unless the thickness when it is stored in the door pocket is about 22 mm or less, but the surface grid type does not have that.
In both types, since there are almost movable screen doors on the inside, the distance from the screen door to the vertical frame is about 35 mm due to the rotation of the louver blades.

Next, the elements common to the two examples will be explained using the small window example in Fig. 1, Fig. 2, Fig. 3, and Fig. 4.
This is because it is easy to explain in the case of a small and cohesive figure.
The blades of the 01_louver are tightened to the 09_interlocking frame on the indoor side and to the 05_vertical frame on the external side.
09_ For the interlocking frame, the connection is completed there.
The 05_vertical frame is rectangular through the 06_upper and lower frames and the 30_corner joint.
06_ The role of the upper and lower frames is 05_ positioning of the vertical frame and suppression of warpage. Therefore, it is necessary to assemble on a horizontal surface plate.

The material of 05_vertical frame, 06_upper and lower frame, and 09_interlocking frame is lightweight channel steel 19 * 10 * 1.0, which is galvanized. It is a mass-produced ready-made product with a medium aggregate under the light iron wall. Zinc paint is rust-proofed at the cut and perforated areas, and finish coating is applied. In Fig. 2, the cross section at the cut position shown in Fig. 1 is shown.
The 30_corner joint material is shown in Fig. 3. In Fig. 3, it is said that there is a 31_hole tap, but after fitting it into the 05_vertical frame and 06_upper and lower frames, make a hole together and cut the tap there. It cuts from mass-produced steel strips with the minimum number of cuts, and chamfers the interference part with the fillet of lightweight channel steel. Zinc paint is rust-proofed on the entire front and back, and finish coating is applied. A hole M3.5 for 35_493 is required for the 30_corner joint material. Therefore, all four are not the same.

The 05_vertical frame and 09_interlocking frame have a row of M2.5 holes at intervals of approximately 50 mm. Positioning will proceed based on the features shown in Fig. 4. As shown in the 101_H-H cross section in Fig. 10, 03, 04 and 493 penetrate, and beyond that, the 02_ blade end bending of the 01_ louver blade also penetrates.
02_ Make a hole in M3 for bending the blade end.

Tap M3 in the holes of 05_vertical frame and 09_interlocking frame. 03 and 04 use the countersunk tapping screw M3. These are the fulcrum hinge and the interlocking hinge, respectively. Since the pitch is different from the M3 tap screw in the hole, 03 and 04 can be tightened respectively.

01_ Make a hole for M3 in 02 of the louver blade. 03, 04 and 493 just fit in the hole, and smooth rotation can be achieved. (03, 04 and 493 do not rotate)
From the tips of the 493 screws at the top and bottom of the interlocking frame, pass a washer with an M2.8 hole in the center of a steel plate of approximately 3.5 * 30 * 1.0, as shown by 88_ in Fig. 8. .. The holes for the four countersunk tapping screws 493, which are combined on the left and right, are M3, which is 0.5 mm larger than the others.

These four 493s are tightened in the 09_interlocking frame part and 02_blade end bending without screws, and only 088_ works, so tighten the 104_gap filling washer in Fig. 10 to make it moderate. It will realize the movement restraint of the blade with a great frictional force. It also functions as a positioning for 09.
For the countersunk heads of 03, 04 and 493, pre-drill the holes of 06 and 09. The countersunk head is almost invisible due to the finish painting. The form is so refreshing that you don't even notice what supports the wings. It is also effective in crime prevention if you cannot find a screw that can be removed.

The cross-sectional shape of the 01_louver blade is shown in Fig. 7, and the partial details are shown in Fig. 8.
This closes the explanation of the example with the small window of the movable louver.
To change the rotation of the blade, simply grab the end of the blade with your fingers and raise or lower it. Due to variations in processing accuracy, moderate resistance naturally occurs, and it does not start moving on its own.
In this example, the support hinge occupies the center of the shape of the blade, and the gravitational eccentric moment is almost zero, so it can be moved lightly at any rotation angle of the blade. See the description in 43_ and 44_ in Figure 4.

The 51_ display in Fig. 5 is a front view of the surface grid type. This outer width is 1798 mm and the outer height is 649 mm. The fineness of the numbers has no particular meaning, but it is the size often found in kitchen windows.
53 is an existing window mounting part, but if it is displayed at the same scale, it is difficult to see, so small parts etc. are explained using the figure of the movable louver for another small window.
01, 05, 06 correspond to the part names in other figures.

The hinge position of 51_ display in Fig. 5 is determined in consideration of the contents of 47_ and 48_ in Fig. 4. It is a little heavy, but if the number of blade stages is 12, there is no problem.
In the installation explanatory view at 52_ in FIG. 5, 56_ is tightened at 57_ in all four places on the outer frame of the existing window, and 59_ and the lower side are placed at two places on the upper side of the assembled movable louver. Tighten 591_ in two places.
The materials of 56_, 59_, and 591_ are made of rust-preventive zinc paint and finish-painted steel plate with a thickness of about 1 mm. The existing window frame is coated with anti-electrolytic paint and a resin washer is applied. Tighten the tapping screw using it, and then apply paint to prevent electrolytic corrosion.

Here is the installation of the movable louver.
562_ Temporary hanging tapping screw is displayed, but it is temporarily hooked on the notch of 593_ attached to 56_. Then, after aligning the holes, tighten the 58_ screw.
Zinc paint is rust-proofed on steel parts, and finish paint is applied on top of it.

The 61_ display in Fig. 6 is a front view of the shutter type. This outer width is 898 mm and the outer height is 1799 mm. The fineness of the numbers has no particular meaning, but it is the size often found in sweep-out windows.
The parts that are increasing from the small window example in Fig. 1 are 65_additional lower frame for shutters, 66_additional upper frame for shutters, 67_lower contact holding hardware lower, 68_lower contact holding hardware upper, 69_upper Adhesion holding hardware for lower, 691_ upper contact holding hardware for upper, 692_ door roller.

65_Additional lower frame for shutters secures the width for mounting the door roller. 06_ The lower frame is lapped and joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attached plate is on the back side.)
66_Additional upper frame for shutters is for inserting movable louvers in the shutter upper groove of the existing fitting upper frame with an appropriate gap. 06_ The upper frame is lap-joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attachment is on the back side of the board.)
Cut the 692_door car over both the 06_lower frame and the additional lower frame for the 65_shado, and install the door car in the cut space. Make a hole in the steel plate with the specified position in advance for fixing the door roller, and tighten it with the countersunk tapping screw.

67_Lower contact holding hardware lower, 68_Lower contact holding hardware upper, 69_Upper contact holding hardware lower, 691_Upper contact holding hardware upper is approximately 22 mm thick when the shutter is stored in the door pocket. It is for securing.
It is made by bending a steel wire, and it is a simple one that uses 03_ as a hinge and hangs it on 04_ with a finger. There is room for improvement to another type, but it will be practical.
Cut approximately 15 * 25 holes in the 09_interlocking frame to make space for handling.

Zinc rust preventive paint is applied to steel parts, and finish paint is applied on top of it.
The explanation of Example 2 is closed here.

Here is a list of related matters.
Fig. 11 shows an example of cross-section enhancement. Not only steel products but also ready-made aluminum products are available on the market, so you can make them stronger or lighter in terms of cost. As for painting, there are some that can be expected to be durable, so you can choose the color you want.

When using all-aluminum products, it is best to use aluminum for joining materials and tightening screws to prevent electrolytic corrosion, and it is necessary to increase the size.

If the horizontal length exceeds 1200 mm as in Example 1, the deflection of the 01_louver blade's own weight is a concern, so the louver is processed upward. Test how much load causes plastic deformation, adjust the conditions, and finish one by multiple operations. By making the upper side of the blade, which is the extension side of this mukuri processing, the overlapping part, it is possible to prevent the gap between the overlapping parts from opening.

01_The color steel plate, which is the material of the louver blade, is made by baking polyester paint on the original plating plate specified by JIS G 3322. As a color steel plate, it is the third grade from the cheapest to the top and is usually mass-marketed. The manufacturer's red rust warranty is usually 11 years. If the air conditions are good, the durability will be much longer. Even after many years, the cross section of the member of the present invention can be easily repainted. If you like the color of the material, you can leave it as it is. The cut surface of the material is likely to rust and will not rust. This is because the aluminum-zinc alloy takes in rust at an early stage.

As for paints, most of the water-based paints can be enjoyed because the popular colors are sold in large quantities from ready-made small cans. The roller brush finishes almost evenly.

To prevent electrolytic corrosion on the existing aluminum frame, apply anti-corrosion paint to the holes and screws before passing the galvanized tapping screws through the holes and then tighten them. A round head seems to be good for the screw head. Apply anticorrosion paint to the screw heads both inside and outside. For washers, apply anticorrosion paint both inside and outside. Avoid anti-corrosion type plastic washers as they are likely to deteriorate quickly with UV rays. As an anticorrosion paint, an oil-based ready-made mass-market paint seems to be good.

Since the cross section of the louver blade of the present invention is tubular, a reinforcing material can be inserted into the hollow part. By making a rectangular cross section of about 4 * 12 with colored steel plate and inserting it over the entire length, it takes time and effort to improve strength and bending performance, but it can be easily realized. There seems to be a demand for crime prevention to lock the door while allowing ventilation at night. It seems that this can also be met.

A material such as a flat belt of a machine can be inserted into the hollow part of the blade. Since it cannot be easily cut with a clipper, etc., it seems that security performance can be expected.

The strength of the colored steel plate and the screw is almost confirmed. For the best strength, for 03 and 04, set the hole in the frame to M3.5 and place a washer inside the blade, as in 493_.

In the present invention, the front view is consciously displayed as the outside side, but it is possible to replace the inside and outside without any trouble. If you can't see the interlocking frame from the outside, it's usually evaluated as smart, but if you have an opinion that you prefer not, you can respond.

Not only used for windows, but also used for outer walls to block sunlight, prevent the temperature rise of the walls and deal with radiant heat, thereby reducing the amount of air conditioning operation and contributing to the suppression of global warming.
In addition, by attaching a sheet-shaped photovoltaic power generation material to about 85% of the surface of the louver blade, it is possible to use it as a heat shield effect for the outer wall and as a power generation resource.
The movable louver of the present invention is made into a suitable size, a Z-axis rotation mechanism is added, and electrification, remote control, and automatic tracking are achieved, which contributes to the improvement of the efficiency of photovoltaic power generation on the wall surface.
The automatic tracking of the previous line is used to concentrate the reflected light on a specific location, and the power generation material is installed in the concentrated location to improve the power generation efficiency. This can also be used for shade protection.

Since it corresponds in each figure, it is omitted.

The present invention relates to a movable louver provided on a window of a building.

Movable louvers of intermediate level or lower for residential use may be seen at a rate of about 1 in 100. You can also buy it online. Almost made of aluminum, it is the color of so-called aluminum sash, and the color of flowers, plants, sky, water, etc. is not seen, and it is surrounded by a solid square frame, and it has a neat shape. I can't see anything.

High-end products such as electric, remote control, full-color, crime prevention, and long louvers are on the market, but they are expensive and generally not widely used.
There are a huge number of houses and buildings, so windows are also important. Window louvers are effective for saving cooling power by saving energy and can be expected to increase in the future, but the price is still high. And since the amount of money per house is small, it seems that there are many difficulties in expanding the business.

Therefore, we hope that simple, easy-to-use, inexpensive, and paintable materials will be proposed and spread using inexpensive commercially available materials. Depending on how it spreads, I think it will be prepared from the design stage of the housing manufacturer.

Patent 3934670 Louver and fittings using it

JP 2017-203345 Blind equipment and fittings

The problem to be solved is that it has a complicated structure and requires a high cost.

The main features of the present invention are that the required functions are narrowed down, the number of members is reduced, and ready-made products are frequently used.

First of all, the movable louver does not have shielding performance. Since there is a window with excellent airtightness and watertightness inside, I think that it is only necessary to secure light shielding and ventilation.
The first feature users want from louvers is that they want to get rid of the hot sun, and they also want the ability to blindfold.
Even if there is no remote control or electric drive, there seems to be no strong demand because it is not operated frequently.

As for the mounting method, if it can be connected to the existing window member, the cost is easily low, and if it can be replaced with the existing shutter, there is almost no treatment to the existing one.
Also, if the shutter shutter is currently used, some users may want to install a movable louver like a surface grid on the outside.

In terms of reducing the number of parts, the hinge shaft for rotating the louver blades is a tapping screw, and the member on the hinge blade side is a blade end bent at a right angle.

For ready-made products, the blade material of the louver is colored steel plate, the surrounding frame and interlocking frame are small size lightweight channel steel, strip steel for joints, rope as a substitute for washers, and ready-made electric power for attachment parts to existing fittings. Anti-corrosion paint, washer for friction tightening part, steel wire for frame close contact holder, shutter door wheel, center-fold screw tightening for locking under shutter, countersunk screw, countersunk tapping screw, pan head tapping screw, each can be obtained immediately It's all about things.

The main parts after processing are louver blades, vertical frames, upper frames, lower frames, interlocking frames, and corner joint members.

The louver blades are made by cutting colored steel plates to the required dimensions and processing them into a flat oval cross-section cylinder with layers. A paint is placed in the overlapped part, and the adhesive strength is expected after it is cured. No joining screws or rivets are used. The smooth surface makes painting easy.

The corner joints of the vertical frame, upper frame, and lower frame are cut at 45 degrees, and the corner joint members are fitted and connected, screw holes are made from the edges, internal screw taps are applied, and tightened with countersunk screws. The corner joint members are coated with zinc rust preventive paint, fitted, and adhered.

Drill holes for M2.5 hinges in rows at intervals of about 50 mm on the vertical frame and interlocking frame. A countersunk tapping screw is used as the hinge shaft.

In most cases, adjust the interval of about 50 mm between the vertical frame and the interlocking frame. This is because it does not make odd-sized louver blades. This also contributes to simplicity. The interval can be obtained by calculating, but since it is difficult to mark, adjust the tension of the elastic measure to realize the reading of millimeters in 1 mm units, preferably in 10 mm units.

The movable louver of the present invention has the advantages of significantly reducing costs, contributing to the prevention of global warming, and delivering comfort and satisfaction to many users.

FIG. 1 is an explanatory view of a movable louver of a small window. In the explanatory drawings and the like of the present invention, the symbols / numbers are common to all the drawings, and the same symbols / numbers are not assigned to different parts or the like.

FIG. 3 is a detailed view of the 30_corner joint material in FIG. FIG. 4 is an explanatory view of louver blades and hinge positions. FIG. 5 shows Example 1 and is an example of a kitchen window-sized surface grid louver. FIG. 6 shows a second embodiment, which is an example of a shutter of a sweep window. FIG. 7 is an explanatory view of a cross section of a louver blade. FIG. 8 is a partial detailed view of the blades of the louver.

FIG. 11 is an explanatory diagram for strengthening the frame material.

Examples are a surface grid example and a shutter example, and explanations will be given with (0028) and (0031) far ahead. Here, the difference between the two examples will be explained in advance.
First, assume the surface grid type of movable louver (not including mounting parts). Then, the shutter type of the movable louver is the one with the additional lower frame and additional upper frame, and the door roller and other small parts attached.
The shutter type has a restriction that it cannot be put in the door pocket unless the thickness when it is stored in the door pocket is about 22 mm or less, but the surface grid type does not have that.
In both types, since there are almost movable screen doors on the inside, the distance from the screen door to the vertical frame is about 35 mm due to the rotation of the louver blades.

Next, the elements common to the two examples will be explained using the small window example in Fig. 1, Fig. 2, Fig. 3, and Fig. 4.
This is because it is easy to explain in the case of a small and cohesive figure.
The blades of the 01_louver are tightened to the 09_interlocking frame on the indoor side and to the 05_vertical frame on the external side.
09_ For the interlocking frame, the connection is completed there.
The 05_vertical frame is rectangular through the 06_upper and lower frames and the 30_corner joint.
06_ The role of the upper and lower frames is 05_ positioning of the vertical frame and suppression of warpage. Therefore, it is necessary to assemble on a horizontal surface plate.

The material of 05_vertical frame, 06_upper and lower frame, and 09_interlocking frame is lightweight channel steel 19 * 10 * 1.0, which is galvanized. It is a mass-produced ready-made product with a medium aggregate under the light iron wall. Zinc paint is rust-proofed at the cut and perforated areas, and finish coating is applied. In Fig. 2, the cross section at the cut position shown in Fig. 1 is shown.
The 30_corner joint material is shown in Fig. 3. In Fig. 3, it is said that there is a 31_hole tap, but after fitting it into the 05_vertical frame and 06_upper and lower frames, make a hole together and cut the tap there. It cuts from mass-produced steel strips with the minimum number of cuts, and chamfers the interference part with the fillet of lightweight channel steel. Zinc paint is rust-proofed on the entire front and back, and finish coating is applied. A hole M3.5 for 35_493 is also required for the 30_corner joint material. Therefore, all four are not the same.

The 05_vertical frame and 09_interlocking frame have a row of M2.5 holes at intervals of approximately 50 mm. Positioning will proceed based on the features shown in Fig. 4. As shown in the 101_H-H cross section in Fig. 10, 03, 04 and 493 penetrate, and beyond that, the 02_ blade end bending of the 01_ louver blade also penetrates.
02_ Make a hole in M3 for bending the blade end.

Tap M3 in the holes of 05_vertical frame and 09_interlocking frame. 03 and 04 use the countersunk tapping screw M3. These are the fulcrum hinge and the interlocking hinge, respectively. Since the pitch is different from the M3 tap screw in the hole, 03 and 04 can be tightened respectively.

01_ Make a hole for M3 in 02 of the louver blade. 03, 04 and 493 just fit in the hole, and smooth rotation can be achieved. (03, 04 and 493 do not rotate)
From the tips of the 493 screws at the top and bottom of the interlocking frame, pass a washer with an M2.8 hole in the center of a steel plate of approximately 3.5 * 30 * 1.0, as shown by 88_ in Fig. 8. I will.

These four 493s are tightened in the 09_interlocking frame part and 02_blade end bending without screws, and only 088_ works, so tighten the 104_gap filling washer in Fig. 10 to make it moderate. It will realize the movement restraint of the blade with a great frictional force. It also functions as a positioning for 09.
For the countersunk heads of 03, 04 and 493, pre-drill the holes of 06 and 09. The countersunk head is almost invisible due to the finish painting. The form is so refreshing that you don't even notice what supports the wings. It is also effective in crime prevention if you cannot find a screw that can be removed.

The cross-sectional shape of the 01_louver blade is shown in Fig. 7, and the partial details are shown in Fig. 8.
This closes the explanation of the example with the small window of the movable louver.
To change the rotation of the blade, simply grab the end of the blade with your fingers and raise or lower it. Due to variations in processing accuracy, moderate resistance naturally occurs, and it does not start moving on its own.
When the support hinge occupies the center of the shape of the blade, the gravitational eccentric moment is almost zero, so it can be moved lightly at any rotation angle of the blade. See the description in 43_ and 44_ in Figure 4.

The 51_ display in Fig. 5 is a front view of the surface grid type. This outer width is 1798 mm and the outer height is 649 mm. The fineness of the numbers has no particular meaning, but it is the size often found in kitchen windows.
53 is an existing window mounting part, but if it is displayed at the same scale, it is difficult to see, so small parts etc. are explained using the figure of the movable louver for another small window.
01, 05, 06 correspond to the part names in other figures.

The hinge position of 51_ display in Fig. 5 is determined in consideration of the contents of 47_ and 48_ in Fig. 4. It is a little heavy, but if the number of blade stages is 12, there is no problem.
In the installation explanatory view at 52_ in FIG. 5, 56_ is tightened at 57_ in all four places on the outer frame of the existing window, and 59_ and the lower side are placed at two places on the upper side of the assembled movable louver. Tighten 591_ in two places.
The materials of 56_, 59_, and 591_ are made of rust-preventive zinc paint and finish-painted steel plate with a thickness of about 1 mm. The existing window frame is coated with anti-electrolytic paint and a resin washer is applied. Tighten the tapping screw using it, and then apply paint to prevent electrolytic corrosion.

Here is the installation of the movable louver.
562_ Temporary hanging tapping screw is displayed, but it is temporarily hooked on the notch of 593_ attached to 56_. Then, after aligning the holes, tighten the 58_ screw.

The 61_ display in Fig. 6 is a front view of the shutter type. This outer width is 898 mm and the outer height is 1799 mm. The fineness of the numbers has no particular meaning, but it is the size often found in sweep-out windows.
The parts that are increasing from the small window example in Fig. 1 are 65_additional lower frame for shutters, 66_additional upper frame for shutters, 67_lower contact holding hardware lower, 68_lower contact holding hardware upper, 69_upper Adhesion holding hardware for lower, 691_ upper contact holding hardware for upper, 692_ door roller.

65_Additional lower frame for shutters secures the width for mounting the door roller. 06_ The lower frame is lapped and joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attached plate is on the back side.)
66_Additional upper frame for shutters is for inserting movable louvers in the shutter upper groove of the existing fitting upper frame with an appropriate gap. 06_ The upper frame is lap-joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attachment is on the back side of the board.)
Cut the 692_door car over both the 06_lower frame and the additional lower frame for the 65_shado, and install it in the cut space. Make a hole in the steel plate with the specified position in advance for fixing the door roller, and tighten it with the countersunk tapping screw.

67_Lower contact holding hardware lower, 68_Lower contact holding hardware upper, 69_Upper contact holding hardware lower, 691_Upper contact holding hardware upper is approximately 22 mm thick when the shutter is stored in the door pocket. It is for securing.
It is made by bending a steel wire, and it is a simple one that uses 03_ as a hinge and hangs it on 04_ with a finger. There is room for improvement to another type, but it will be practical.
Cut approximately 15 * 25 holes in the 09_interlocking frame to make space for handling.

Zinc rust preventive paint is applied to steel parts, and finish paint is applied on top of it.
The explanation of Example 2 is closed here.

Here is a list of related matters.
Fig. 11 shows an example of cross-section enhancement. Not only steel products but also ready-made aluminum products are available on the market, so you can make them stronger or lighter in terms of cost. As for painting, there are some that can be expected to be durable, so you can choose the color you want.

When using aluminum products, it is best to use aluminum for joining materials and tightening screws to prevent electrolytic corrosion, and it is necessary to increase the size.

If the horizontal length exceeds 1200 mm as in Example 1, the deflection of the 01_louver blade's own weight is a concern, so the louver is processed upward. We test how much load causes plastic deformation, adjust the conditions, and finish one by working in multiple places. By making the upper side of the blade, which is the extension side of this mukuri processing, the overlapping part, it is possible to prevent the gap between the overlapping parts from opening.

01_The color steel plate, which is the material of the louver blade, is made by baking polyester paint on the original plating plate specified by JIS G 3322. As a color steel plate, it is the third grade from the cheapest to the top and is usually mass-marketed. The manufacturer's red rust warranty is usually 11 years. If the air conditions are good, the durability will be much longer. Even after many years, the cross section of the member of the present invention can be easily repainted. If you like the color of the material, you can leave it as it is. The cut surface of the material is likely to rust and will not rust. This is because the aluminum-zinc alloy takes in rust at an early stage.

As for paints, most of the water-based paints can be enjoyed because the popular colors are sold in large quantities from ready-made small cans. The roller brush finishes almost evenly.

To prevent electrolytic corrosion on the existing aluminum frame, apply anti-corrosion paint to the holes and screws before passing the galvanized tapping screws through the holes and then tighten them. A round head seems to be good for the screw head. Apply anticorrosion paint to the screw heads both inside and outside. For washers, apply anticorrosion paint both inside and outside. Avoid anti-corrosion type plastic washers as they are likely to deteriorate quickly with UV rays. As an anticorrosion paint, an oil-based ready-made mass-market paint seems to be good.

Since the cross section of the louver blade of the present invention is tubular, a reinforcing material can be inserted into the hollow part. By making a rectangular cross section of about 4 * 12 with colored steel plate and inserting it over the entire length, it takes time and effort to improve strength and bending performance, but it can be easily realized. There seems to be a request for crime prevention when locking while allowing ventilation at night, so it seems that we can meet this as well.

A material such as a flat belt of a machine can be inserted into the hollow part of the blade. Since it cannot be easily cut with a clipper, etc., it seems that security performance can be expected.

The strength of the colored steel plate and the screw is almost confirmed. For the best strength, washers are placed inside the blades for 03 and 04, as in 493_.

In the present invention, the front view is consciously displayed as the outside side, but it is possible to replace the inside and outside without any trouble. If you can't see the interlocking frame from the outside, it's usually evaluated as smart, but if you have an opinion that you prefer not, you can respond.

Not only for windows, but also for outer walls, it blocks sunlight, prevents the temperature of the walls from rising, and copes with the radiant heat of the walls, thereby reducing the amount of air conditioning operation and contributing to the suppression of global warming.
In addition, by attaching a sheet-shaped photovoltaic power generation material to about 85% of the surface of the louver blade, it is possible to use it as a heat shield effect for the outer wall and as a power generation resource.
The movable louver of the present invention is made into a suitable size, a Z-axis rotation mechanism is added, and electrification, remote control, and automatic tracking are achieved, which contributes to the improvement of the efficiency of photovoltaic power generation on the wall surface.
The automatic tracking of the previous line is used to concentrate the reflected light on a specific location, and the power generation material is installed in the concentrated location to improve the power generation efficiency. This can also be used for shade protection.

Since it corresponds in each figure, it is omitted.

The present invention relates to a movable louver provided on a window of a building.

Movable louvers of intermediate level or lower for residential use may be seen at a rate of about 1 in 100. You can also buy it online. Mostly made of aluminum, it is the color of so-called aluminum sash, and the color of flowers, plants, sky, water, etc. is not seen, and it is surrounded by a solid square frame, and it has a neat shape. I can't see anything.

High-end products such as electric, remote control, full-color, crime prevention, and long louvers are on the market, but they are expensive and generally not widely used.
There are a huge number of houses and buildings, so windows are also important. Window louvers are effective for saving cooling power by saving energy and can be expected to increase in the future, but the price is still high. And since the amount of money per house is small, it seems that there are many difficulties in expanding the business.

Therefore, we hope that simple, easy-to-use, inexpensive, and paintable materials will be proposed and spread using inexpensive commercially available materials. Depending on how it spreads, I think it will be prepared from the design stage of the housing manufacturer.

Patent 3934670 Louver and fittings using it

JP 2017-203345 Blind equipment and fittings

The problem to be solved is that it has a complicated structure and requires a high cost.

The main features of the present invention are that the required functions are narrowed down, the number of members is reduced, and ready-made products are frequently used.

First of all, the movable louver does not have shielding performance. Since there is a window with excellent airtightness and watertightness inside, I think it is only necessary to secure light shielding and ventilation.
The first feature users want from louvers is that they want to get rid of the hot sun, and they also want the ability to blindfold.
Even if there is no remote control or electric drive, there seems to be no strong demand because it is not operated frequently.

As for the mounting method, if it can be connected to the existing window member, the cost is easily low, and if it can be replaced with the existing shutter, there is almost no treatment to the existing one.
Also, if the shutter shutter is currently used, some users may want to install a movable louver like a surface grid on the outside.

In terms of reducing the number of parts, the hinge shaft for rotating the louver blades is a tapping screw, and the member on the hinge blade side is a blade end bent at a right angle.

For ready-made products, the blade material of the louver is colored steel plate, the surrounding frame and interlocking frame are small size lightweight channel steel, the joint is steel strip, the rope is used as a washer substitute, and the ready-made electric wire is used for the attachment part to the existing fittings. Anti-corrosion paint, washer for anti-friction part, steel wire for frame contact holder, steel wire for shutter door wheel, center-fold screw tightening for locking under shutter, countersunk screw, countersunk tapping screw, pan head tapping screw, each available immediately It's just.

The main parts after processing are louver blades, vertical frames, upper frames, lower frames, interlocking frames, and corner joint members.

The louver blades are made by cutting colored steel plates to the required dimensions and processing them into a flat oval cross-section cylinder with layers. A paint is placed in the overlapped part, and the adhesive strength is expected after it is cured. No joining screws or rivets are used. The smooth surface makes painting easy.

For the corner joints of the vertical frame, upper frame, and lower frame, cut them at 45 degrees, fit and connect the corner joint members, make screw holes from the edges, apply internal screw taps, and tighten with countersunk screws. Zinc rust preventive paint is applied to the corner joint members, and they are fitted and adhered.

Drill holes for M2.5 hinges in rows at intervals of about 50 mm on the vertical frame and interlocking frame. A countersunk tapping screw is used as the hinge shaft.

In most cases, adjust the interval of about 50 mm between the vertical frame and the interlocking frame. This is because it does not make odd-sized louver blades. This also contributes to simplicity. The interval can be obtained by calculating, but since it is difficult to mark, adjust the tension of the elastic measure to realize the reading of millimeters in 1 mm units, preferably in 10 mm units.

The movable louver of the present invention has the advantages of significantly reducing costs, contributing to the prevention of global warming, and delivering comfort and satisfaction to many users.

Examples are a surface grid example and a shutter example, and explanations will be given with (0028) and (0031) far ahead. Here, the difference between the two examples will be explained in advance.
First, assume the surface grid type of movable louver (not including mounting parts). Then, the shutter type of the movable louver is the one with the additional lower frame and additional upper frame, and the door roller and other small parts attached.
The shutter type has a restriction that it cannot be put in the door pocket unless the thickness when it is stored in the door pocket is about 22 mm or less, but the surface grid type does not have that.
In both types, since there are almost movable screen doors on the inside, the distance from the screen door to the vertical frame is about 35 mm due to the rotation of the louver blades.

Next, the elements common to the two examples will be explained using the small window example in Fig. 1, Fig. 2, Fig. 3, and Fig. 4.
This is because it is easy to explain in the case of a small and cohesive figure.
The blades of the 01_louver are tightened to the 09_interlocking frame on the indoor side and to the 05_vertical frame on the external side.
09_ For the interlocking frame, the connection is completed there.
The 05_vertical frame is rectangular through the 06_upper and lower frames and the 30_corner joint.
06_ The role of the upper and lower frames is 05_ positioning of the vertical frame and suppression of warpage. Therefore, it is necessary to assemble on a horizontal surface plate.

The material of 05_vertical frame, 06_upper and lower frame, and 09_interlocking frame is lightweight channel steel 19 * 10 * 1.0, which is galvanized. It is a mass-produced ready-made product with a medium aggregate under the light iron wall. Zinc paint is rust-proofed at the cut and perforated areas, and finish coating is applied. In Fig. 2, the cross section at the cut position shown in Fig. 1 is shown.
The 30_corner joint material is shown in Fig. 3. In Fig. 3, it is said that there is a 31_hole tap, but after fitting it into the 05_vertical frame and 06_upper and lower frames, make a hole together and cut the tap there. It cuts from mass-produced steel strips with the minimum number of cuts, and chamfers the interference part with the fillet of lightweight channel steel. Zinc paint is rust-proofed on the entire front and back, and finish coating is applied. A hole M3.5 for 35_493 is also required for the 30_corner joint material. Therefore, all four are not the same.

The 05_vertical frame and 09_interlocking frame have a row of M2.5 holes at intervals of approximately 50 mm. Positioning will proceed based on the features shown in Fig. 4. As shown in the cross section of 101_H-H in Fig. 10, 03_, 04_ and 493_ penetrate, and beyond that, 02_ blade end bending of the 01_ louver blade also penetrates.
02_ Make a hole in M3 for bending the blade end.

Tap M3 in the holes of 05_vertical frame and 09_interlocking frame. 03_ and 04_ use the countersunk tapping screw M3. These are the fulcrum hinge and the interlocking hinge, respectively. Since the pitch is different from the M3 tap screw in the hole, 03_ and 04_ can be tightened respectively.

01_ Make a hole for M3 in 02_ of the louver blade. 03_, 04_ and 493_ just fit in the hole, and smooth rotation can be achieved. (03_, 04_ and 493_ do not rotate)
From the tip of the 493_ screw at the top and bottom of the interlocking frame, as shown by 88_ in Fig. 8, a washer with an M2.8 hole in the center of a steel plate of approximately 3.5 * 30 * 1.0. Let it through.

These four 493_ are tightened in the 09_interlocking frame part and 02_blade end bending without screws, and only 088_ works, so tighten the 104_gap filling washer in Fig. 10 and tighten it. It will realize the movement restraint of the blade with an appropriate frictional force. It also functions as a positioning for 09_.
For the countersunk heads of 03_, 04_ and 493_, pre-drill the holes of 06_ and 09_. The countersunk head is almost invisible due to the finish painting. The form is so refreshing that you don't even notice what supports the wings. It is also effective in crime prevention if you cannot find a screw that can be removed.

The cross-sectional shape of the 01_louver blade is shown in Fig. 7, and the partial details are shown in Fig. 8.
This closes the explanation of the example with the small window of the movable louver.
To change the amount of rotation of the blade, simply grab the end of the blade with your fingers and raise or lower it. Due to variations in processing accuracy, moderate resistance naturally occurs, and it does not start moving on its own.
When the support hinge occupies the center of the shape of the blade, the gravitational eccentric moment is almost zero, so it can be moved lightly at any rotation angle of the blade. See the description in 43_ and 44_ in Figure 4.

The 51_ display in Fig. 5 is a front view of the surface grid type. This outer width is 1798 mm and the outer height is 649 mm. There is no particular meaning to the fineness of the numbers, but it is the size often found in kitchen windows.
53_ is an existing window mounting part, but if it is displayed at the same scale, it will be difficult to see, so small parts etc. are explained using the figure of the movable louver for another small window.
01_, 05_, 06_ correspond to the part names in other figures.

The hinge position of 51_ display in Fig. 5 is determined in consideration of the contents of 47_ and 48_ in Fig. 4. It is a little heavy, but if the number of blade stages is 12, there is no problem.
In the installation explanatory view at 52_ in FIG. 5, 56_ is tightened at 57_ in all four places on the outer frame of the existing window, and 59_ and the lower side are placed at two places on the upper side of the assembled movable louver. Tighten 591_ in two places.
The materials of 56_, 59_, and 591_ are made of rust-preventive zinc paint and finish-painted steel plate with a thickness of about 1 mm. The existing window frame is coated with anti-electrolytic paint and a resin washer is applied. Tighten the tapping screw using it, and then apply paint to prevent electrolytic corrosion.

Here is the installation of the movable louver.
562_ Temporary hanging tapping screw is displayed, but it is temporarily hooked on the notch of 593_ attached to 56_. Then, after aligning the holes, tighten the 58_ screw.

The 61_ display in Fig. 6 is a front view of the shutter type. This outer width is 898 mm and the outer height is 1799 mm. The fineness of the numbers has no particular meaning, but it is the size often found in sweep-out windows.
The parts that are increasing from the small window example in Fig. 1 are 65_additional lower frame for shutters, 66_additional upper frame for shutters, 67_lower contact holding hardware lower, 68_lower contact holding hardware upper, 69_upper Adhesion holding hardware for lower, 691_ upper contact holding hardware for upper, 692_ door roller.

65_Additional lower frame for shutters secures the width for mounting the door roller. 06_ The lower frame is lapped and joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attached plate is on the back side.)
66_Additional upper frame for shutters is for inserting movable louvers in the shutter upper groove of the existing fitting upper frame with an appropriate gap. 06_ The upper frame is lapped and joined using a steel plate with a steel plate of approximately 10 * 17 * 1.0. (The figure is omitted. The attachment is on the back side of the board.)
Cut the 692_door car over both the 06_lower frame and the additional lower frame for the 65_shado, and install it in the cut space. Make a hole in the steel plate with the specified position in advance for fixing the door roller, and tighten it with the countersunk tapping screw.

67_Lower contact holding hardware lower, 68_Lower contact holding hardware upper, 69_Upper contact holding hardware lower, 691_Upper contact holding hardware upper is approximately 22 mm thick when the shutter is stored in the door pocket. It is for securing.
It is made by bending a steel wire, and it is a simple one that uses 03_ as a hinge and hangs it on 04_ with a finger. There is room for improvement to another type, but it will be practical.
Approximately 15 * 25 holes are cut in the 09_interlocking frame to make space for handling close contact holding hardware.

Zinc rust preventive paint is applied to steel parts, and finish paint is applied on top of it.
The explanation of Example 2 is closed here.

Here is a list of related matters.
Fig. 11 shows an example of cross-section enhancement. Not only steel products but also ready-made aluminum products are available on the market, so you can make them stronger or lighter in terms of cost. As for painting, there are some that can be expected to be durable, so you can choose the color you want.

When using aluminum products, it is best to use aluminum for joining materials and tightening screws to prevent electrolytic corrosion, but it is necessary to increase the size to ensure strength.

If the horizontal length exceeds 1200 mm as in Example 1, the deflection of the 01_louver blade's own weight is a concern, so the louver is processed upward. We test how much load causes plastic deformation, adjust the conditions, and finish one by working in multiple places. By making the upper side of the blade, which is the extension side of this mukuri processing, the overlapping part, it is possible to prevent the gap between the overlapping parts from opening.

01_The color steel plate, which is the material of the louver blade, is made by baking polyester paint on the original plating plate specified by JIS G 3322. As a color steel plate, it is the third grade from the cheapest to the top and is usually mass-marketed. The manufacturer's red rust warranty is usually 11 years. If the air conditions are good, the durability will be much longer. Even after many years, the cross section of the member of the present invention can be easily repainted. If you like the color of the material, you can leave it as it is. The cut surface of the material is likely to rust and will not rust. This is because the aluminum-zinc alloy takes in rust at an early stage.

As for paints, most of the water-based paints are easy to enjoy because the popular colors are sold in large quantities from ready-made small cans. The roller brush finishes almost evenly.

To prevent electrolytic corrosion on the existing aluminum frame, apply anti-corrosion paint to the holes and screws before passing the galvanized tapping screws through the holes and then tighten them. A round head seems to be good for the screw head. Apply anticorrosion paint to the screw heads both inside and outside. For washers, apply anticorrosion paint both inside and outside. Avoid anti-corrosion type plastic washers as they are likely to deteriorate quickly with UV rays. As an anticorrosion paint, an oil-based ready-made mass-market paint seems to be good.

Since the cross section of the louver blade of the present invention is tubular, a reinforcing material can be inserted into the hollow part. By making a rectangular cross section of about 4 * 12 with colored steel plate and inserting it over the entire length, it is easy to improve the strength and bending performance, although it takes time. There seems to be a request for crime prevention when locking while allowing ventilation at night, so it seems that we can meet this as well.

A material such as a flat belt of a machine can be inserted into the hollow part of the blade. Since it cannot be easily cut with a clipper, etc., it seems that security performance can be expected.

The strength of the colored steel plate and the screw is almost confirmed. For the best strength, washers are placed inside the blades for 03_ and 04_, as in 493_.

In the present invention, the front view is consciously displayed as the outside side, but it is possible to replace the inside and outside without any trouble. If you can't see the interlocking frame from the outside, it's usually evaluated as smart, but if you have an opinion that you prefer not, you can respond.

Not only for windows, but also for outer walls, it blocks sunlight, prevents the temperature of the walls from rising, and copes with the radiant heat of the walls, thereby reducing the amount of air conditioning operation and contributing to the suppression of global warming.
In addition, by attaching a sheet-shaped photovoltaic power generation material to about 85% of the surface of the louver blade, it is possible to use it as a heat shield effect for the outer wall and as a power generation resource.
The movable louver of the present invention is made into a suitable size, a Z-axis rotation mechanism is added, and electrification, remote control, and automatic tracking are achieved, which contributes to the improvement of the efficiency of photovoltaic power generation on the wall surface.
The automatic tracking of the previous line is used to concentrate the reflected light on a specific location, and the power generation material is installed in the concentrated location to improve the power generation efficiency. This can also be used for shade protection.

Since it corresponds in each figure, it is omitted.
