2. Description of the Related Art In recent years, with the progress of energy saving for heating and cooling, heat transmission coefficient (amount of energy lost per square meter per hour when the temperature difference between inside and outside is 1 degree) in a house or a building. The window and doors using double glazing have been supplied as measures against this. FIG. 14 shows a sash using a conventional double glazing, in which the double glazing in which the glass 2 and the glass 3 are laminated facing each other via the separator 1 is fixed to the outer frame 5 via the buffer packing 4. The outer frame 5 was used as a window or a door by attaching a groove, a pulley or a handle. With this configuration, the air layer 6 in the double glazing works as a heat insulating material, and has a heat transmission coefficient of about 1/2 of that of the single glazing.

[0003]

However, regardless of whether a new house or building is to be built, many existing houses and buildings are already made up of single-glazed windows and doors, and it is necessary to replace them with double-glazed glass. Is extremely difficult, and windows and doors made of double glazing have a commercial price about twice that of single glazing, and are used only in special cases in snowy regions and cold regions. In addition, since direct sunlight comes in directly in summer, it must be used in combination with blinds and curtains.

In view of the above-mentioned problems, the present invention provides a conventional single-layer glass window or door having a heat insulating device which has a simple double-layer structure to reduce the heat transmission coefficient. Further, the present invention provides a new light-shielding structure using the multi-layer structure of the daylighting section.

According to the glass frame shape (glass portion shape) of the window or door, the translucent polymer material faces the glass of the window or door at a constant interval, and the periphery of this is in contact with the glass. The cross-section is configured in a U shape, and adhesive, adhesive, crimp,
It is fixed to glass or a glass frame by a fixing means such as a suction cup or a screw. With this configuration, a closed air layer is formed between the (window) glass and the heat insulating device formed in a substantially U shape, so that the heat transmission coefficient can be reduced. 2. It is made of translucent glass or polymer material in which light-shielding parts (light-reducing parts) and light-transmitting parts are alternately constituted by stripes or cross-shaped grids or any design pattern, and which are close to or in contact with each other and which face each other. One of the two sheets, the mesh, or the slit is fixed, and the other is held so as to be movable in the pitch direction to form a light shielding (dimming) device. With the above configuration, one sheet is moved in the pitch direction by about a half pitch to shield the light from the transparent state (dimming).
It is possible to instantly switch the state or the light-shielding (dimming) state to the light-transmitting state.

(Embodiment 1) In the following, an embodiment of a heat insulating device having a conventional double-layer glass window or door and having a simple double-layer structure to reduce the heat transmission coefficient will be described with reference to FIGS.

FIG. 1 is an embodiment showing a method of using the heat insulating device according to the present invention, in which a translucent polymer material and glass are used in a certain amount in accordance with the shape (glass portion shape) of the glass frame 12 of the window 11. A heat insulating device 13 having a substantially U-shaped cross section so as to face each other at intervals is fixed at its outer periphery 14 to the glass 15 or the glass frame 12 by a fixing means such as adhesion or adhesion.

FIG. 2 shows the fixing means of FIG. 1 in which the contact surface of the heat insulating device 13 formed in a substantially U shape with the glass is attached to the glass 15 by a fixing means such as an adhesive or an adhesive 16. . Reference numeral 17 is a cushioning rubber that seals the gap and protects the glass from an impact. With this configuration, (window) glass,
Since a closed air layer is formed between the heat insulating devices formed in a substantially U shape, the heat transmission coefficient can be reduced.

FIG. 3 shows an embodiment in which a spacer is formed on the outer periphery of the sheet, and the shape of the window glass frame 12 (the shape of the glass portion).
A transparent glass or polymer film or sheet 18 having a thickness of 0.05 to 5 mm and a frame 1 also serving as a spacer so as to face the outer periphery of the glass at a constant interval.
9, and these are attached to the glass 15 by a fixing means such as an adhesive or an adhesive 20. With this configuration, a closed air layer is formed between the (window) glass 15 and the heat insulating device constituted by the sheet 18 and the frame 19 also serving as a spacer, so that the heat transmission coefficient can be lowered. . Further, even if a thin and light film is used, it can be stretched tightly by the frame 19 which also serves as a spacer, so that it looks good. In the above, the film or sheet may be a material that expands and contracts like rubber, cloth or fine mesh. In the case of rubber, even if it hits accidentally, it will return to the original state, and in the case of cloth or mesh, it can be evaporated even if there is moisture between it and the glass.

FIG. 4 shows another embodiment of the fixing means of FIG. 1, in which a heat insulating device 21 and a suction cup 22 which are formed in a substantially U-shape are press-fitted into the press-fitting portion 2.
3 and the suction cup 22 is fixed to the glass 15 by adsorbing it onto the glass 15. Reference numeral 24 denotes a packing portion formed by the outer circumference of the heat insulating device 21, which seals the air inside and enhances the heat insulating effect. With this configuration, the packing section prevents the internal air from convection into the room, so that the heat transmission coefficient is low. In addition, the window glass can be cleaned, the heat insulation device can be replaced, or it can be easily removed at any time.

FIG. 5 shows an embodiment in which the surface facing the glass 15 is embossed (or corrugated) 26, even when the film is pressed or when a thin and flexible film 27 is used (window) glass 15 With a certain interval can be opened.

(Embodiment 2) Next, an example of a new light-shielding structure using the multi-layer structure of the daylighting section will be described with reference to FIGS.

FIG. 6 shows a light-shielding device having a multi-layer structure in which a light-shielding portion (light-reducing portion) and a light-transmitting portion are constituted by a stripe-shaped or grid-shaped pattern, and stripe-shaped or grid-shaped patterns having the same pitch. The first sheet 34, which is made up of two transparent glass or polymer materials, which are close to and face each other and which form the light-shielding portions (light-reducing portions) 30 and 31 and the light-transmitting portions 32 and 33, A sheet holding portion 40 fixed to 36 and 37 and having a second sheet 35 rotatably attached to both ends of the arms 38 and 39, respectively.
And 41 and 42 and 43 hold the light shielding portion and the light transmitting portion in parallel with each other in the pitch direction, and a lever 45 that moves 44 around the rotation center, and a sheet holding portion 41 via a connecting portion 46. A light-shielding (light-reducing) device is configured by a mechanism that transmits stress to the. It should be noted that the spring 47 generates a switching feel to the lever 45 at the time of switching, and
It holds the position of.

FIG. 6A shows the light shielding portion 3 of the first sheet 34.
A state where the lever 45 is lowered so that 0 and the light shielding portions 31 of the second sheet 35 are alternately arranged is shown in the light shielding state. In FIG. 6B, the lever 35 is switched, and the compression force of the spring 47 causes the sheet 35 to instantaneously move in parallel to the specified dimension, so that the sheet 35 and the transparent portion 32 of the first sheet 34 are moved. Second sheet 35
Since the light-transmitting portions 33 of the above are arranged to face each other, a light-transmitting state is achieved.

In the above, when configuring the light shielding device,
Ideally, the light-shielding portion and the light-transmitting portion should have the same width dimension, but the light-shielding portion may be slightly larger because light may leak obliquely or the sheet movement pitch may shift. It is preferable. Further, when configuring the light reducing device, it can be implemented by making the width of the light transmitting portion larger than the width of the light shielding portion. The shorter the pitch (line) of the light-shielding portion and the light-transmitting portion (the thinner), the less visually noticeable. (The outside scenery looks natural.) When the light-shielding portion is formed by printing, the pitch is preferably about 0.3 to 3.0 mm. The light-shielding portion may be formed by roughening the surface by blasting or laser treatment. In this case, when the light is shielded, the light is diffused and becomes blind as in the case of ground glass.

The light shielding portions 30 and 31 of the first sheet and the second sheet are changed in color by a reflector such as aluminum plating or a color ink when light is shielded and light is transmitted. You can change the apparent color. Furthermore, by expressing a picture or a character on the light shielding part, the picture or the character can be made to stand out when the light is shielded. Further, in the light-shielding device, the light-shielding portion may be formed of a light-reducing ink (filter) or vapor deposition plating of aluminum or the like used for sunglasses, so that the light-reducing device looks dark. Needless to say, the sheet material may be a filter material such as smoke. With the above structure, by moving one sheet by a half pitch in the pitch direction, it is possible to instantaneously switch from the light-transmitting state to the light-blocking (dimming) state or from the light-blocking state to the light-transmitting state. There is.

FIG. 7 shows a push-button type light-shielding device in which a lock mechanism is constituted by a claw, and light-shielding portions (light-reducing portions) 50 and 51 and a light-transmitting portion 52 are formed from stripe-shaped or grid-shaped patterns of the same pitch. First sheet 5 formed of two translucent glass or polymer materials which are close to each other and which constitute 53

A push button 60 that is formed and has a push-lock mechanism formed by the claws 59, a release push button 61 that removes the protrusion 58 from the claw 59, and a spring 62 that pushes down each push button.
And a spring 63 that presses the sheet holding frame 57 toward the push lock mechanism side constitutes a light shielding (dimming) device.

FIG. 7A shows a state in which the push button 60 is pressed so that the light shielding portions 50 of the first sheet 54 and the light shielding portions 51 of the second sheet 55 are alternately arranged. Indicates. Since the claw 59 locks the protrusion 58, the second sheet 55 moves in a direction of compressing the spring 63.

When 8 moves to the left and disengages from the claw 59, the spring 62
The push button 60 is pushed down by the stress of, and the compressive stress of the spring 63 moves the sheet holding frame 57 to the right of the locked state. FIG. 7C is a front view of parts of the push button 60 and the release push button 61 having the protrusion 59.

FIG. 8 shows a push-lock push-release mechanism composed of the push button and the release push button shown in FIG. 7, which is composed of a heart groove, a rod rod and one push button. , H
A T-shaped groove 65 is formed, and a step 67 is formed so that the rod rod 66 can move in only one direction.
FIG. 8A shows a state in which the rod bar 66 is in the deep groove.
When the push button 64 is pressed once from this state, the rod bar 66 moves along the groove indicated by the arrow A and is locked in the state of FIG. 8B by the compressive stress of the spring 68. When the push button 64 is pressed again, the rod bar 66 moves along the groove indicated by arrow a, and the compressive stress of the spring 68 causes
It is locked in the state shown in FIG.
Repeat this each time you press. The moving dimension of the lot rod 66 in FIGS. 8A and 8B becomes c, and by adjusting this to the pitch of the light-shielding portion, the sheet moves by the push button operation. Even when the pitch between the light-shielding portion (or the light-reducing portion) and the light-transmitting portion configured as described above is narrowed, the light-shielding state and the light-transmitting state can be switched with one touch. It should be noted that buttons and knobs such as a push-lock mechanism used for ball pens and the like, a mechanism that converts the rotary knob to a linear motion from a rotary motion by a crank, or a slide motion by a lever. Alternatively, a mechanism may be used in which the sheet moves by a specified dimension by operating a lever or a lever.

FIG. 9 shows two sheets with elastic spaces.
In the embodiment in which the light beams are connected to each other by a saw, light shielding portions (light reducing portions) 70 and 71 and a light transmitting portion 7 are formed from stripe-shaped or grid-shaped patterns having the same pitch.
The first sheet 74 and the second sheet 75, which are composed of two light-transmissive glasses or polymer materials, which face each other and which constitute 2, 73 and are closely opposed to each other, are made of elastic elastomer resin or rubber. Connected by the spacer 77 with the formed suction cup, the second
A light shield (light reduction) device is constructed by disposing a plunger 78 at one end of the sheet 75 in the light shielding portion pattern pitch direction and an extruding rod 79 having a built-in spring at the other end. Reference numeral 76 is a fixing member for fixing the plunger 78 and the pushing rod 79 to the first sheet.

0 and 71 are alternately arranged to be in a light shielding (dimming) state. FIG.
(B) is a state where the plunger 78 is stopped and the second rod 75 is moved upward by the push rod 79 having a built-in spring. Dimmed). Note that the plunger-78 uses a self-holding type with a built-in permanent magnet, so that it is not necessary to conduct electricity except when switching. By adopting the above configuration, a car window, a sun roof, a house window, etc.
Anything with a suction cup attached can be attached, and
Thin, light-blocking (dimming) that can be operated remotely by electric operation
Can supply equipment. In the above description, the first sheet and the second sheet, which form the light-shielding portion (light-reducing portion) and the light-transmitting portion from the stripe-shaped pattern or the grid-shaped pattern having the same pitch, have the same pitch. The same effect can be obtained by using a mesh or slit. Further, instead of the sheet, a material such as a polymer film, metal, cloth or paper may be used. In particular, meshes and slits can be easily mass-produced by molding plastic or pressing or etching iron or aluminum plates. Also,
Assuming that the pitch between the light-shielding portion and the light-transmitting portion is 1 mm, the movement amount of the second sheet may be 0.5 mm, and since there is almost no movement dimension, it may be arbitrarily curved. (The same applies to the other examples.)

FIG. 10 shows an embodiment in which the present invention is retrofitted to a window, and shows a light shielding device in which a substantially U-shaped sheet and a movable sheet are connected by an elastic spacer. A first sheet 81 having a light-shielding portion and a light-transmitting portion having a constant pitch and formed in a substantially U-shape, and a second sheet 82 having the light-shielding portion and the light-transmitting portion having the same pitch are elastic. The contact surface of the first sheet 81, which is connected in a substantially U-shape and is connected by a spacer 83 formed of a certain elastomer resin or rubber, to the glass is fixed by a fixing means such as an adhesive or an adhesive 16. It is attached to the glass 15. Reference numeral 84 denotes a metal fitting fixed to the second sheet, in which a permanent magnet 85 fixed to the first sheet 81 and an electromagnet 86 composed of a coil are arranged so as to face each other.

In operation, when the electromagnet 86 is matched with the polarity of the permanent magnet 85, the magnetic force increases, so that the metal fitting 84 is pulled as shown in FIG. 10A and the electromagnet 86 is made opposite to the polarity of the permanent magnet 85, the magnetic force disappears. Therefore, as shown in FIG. 10B, the metal fitting 84 returns to its original position by the elasticity of the spacer 83.
When the electromagnet is off, the magnetic force of the permanent magnet 85 causes the metal fitting 84 to be pulled close to the metal fitting 84, and when the metal fitting 84 is separated from the metal fitting 84, the pulling power is insufficient to keep the metal fitting 84 apart, and the previous state is maintained. . The first sheet 81
May be formed as shown in FIG. 3, and the light shielding device may be configured so that the second sheet is inserted inside. With the above structure, since the light shielding device can be formed in the multi-layer plate, it is possible to prevent the second sheet of the movable part from being touched by hand and to provide the light shielding device having the heat insulating effect by the air layer which does not convection.
In the above, the first and second sheets may be meshes or slits and may be formed by molding plastic or pressing or etching an iron or aluminum plate. If the pitch between the light shielding portion and the light transmitting portion is 1 mm, the movement amount of the second sheet is 0.5 mm and the light shielding function works 100%.
Since it has almost no moving dimension, it may be curved according to the glass to be connected.

FIG. 11 shows an embodiment in which a device for adjusting the amount of light shielding is incorporated in the light shielding device of the present invention, and FIG. 11 (a) shows a sectional view of the construction. A first sheet 88 fixed to the frame 87 and having a light blocking portion and a light transmitting portion having the same pitch, and a second sheet 90 having a light blocking portion and a light transmitting portion having the same pitch fixed to the movable frame 89. Are connected to a movable frame 89 via a motor 91 fixed to a frame 87 and a screw screw 92, and a light emitting portion 94 and a light receiving portion 95 face each other with the first sheet and the second sheet interposed therebetween. It is arranged and configured as described below. Reference numeral 93 is a spring for preventing play.

FIG. 11B shows a circuit block diagram for adjusting the light shielding amount. In the structure of FIG. 11A, light is emitted from the light emitting element 94, and the first sheet 88 and the second sheet 88 are emitted.
The light that has been dimmed by the light receiving element 95 is received via the port 90, and the light amount is converted into data (or voltage) by the light shielding amount detection unit.
On the other hand, the operator sets an arbitrary shading amount on the shading amount setting unit. The light-shielding amount controller compares these two data (or voltage) and sets the light-shielding amount in the opening direction if the light amount is insufficient, and sets the light-shielding amount in the closing direction if the light amount is large. The drive mechanism is controlled so as to move the second sheet 90 until it matches the set value of the unit. With the above configuration, the light blocking amount of the light blocking device can be freely set by electrical control.

FIG. 12 shows an embodiment in which the present invention is applied to a sash of double-glazing. With the fixed frame 101, the glass 103 and the light shielding portion 1 via the cushion packing 102.
A slit 108 having a light-shielding portion 107 supported by a movable frame 106 is arranged between a plurality of double-glazings formed by fixing a glass 105 with a fixed frame 101 and a movable frame 1.
06 is connected via a pressure transmitting element 109 to form a light-shielding device of double glazing. FIG. 12A shows a state in which no voltage is applied to the piezoelectric element 109, and
And 107 face each other, so that they are in a light-transmitting state. FIG.
(B) shows a state in which a voltage is applied to the piezoelectric element 109,
The movable frame 106 moves due to the bending of the piezoelectric element 109, and the light shielding portions 104 and 107 alternately face each other, so that the light shielding state is achieved. According to the above configuration, since the piezoelectric element is used, almost no current flows and power consumption can be suppressed. In the above configuration, if a bimetal is arranged instead of the piezoelectric element, it is possible to add a function of automatically switching depending on the ambient temperature, for example, a transparent state when it is cold and a light blocking state when it is hot. Also, this function may be used in combination with another method.

FIG. 13 shows an embodiment in which a daylighting window is constructed in the present invention. A first sheet 114 having a mountain-shaped lens 113 (or a semi-cylindrical or knurled lens) of the same pitch is fixed to a fixed frame 111 via a cushion packing 112, and the same pitch is provided near the focal point of this lens. A second sheet 117 having a light-shielding portion 115 (or a light-reducing portion) and a light-transmitting portion 116 formed in a striped pattern (or a checkerboard pattern) is fixedly arranged on the movable frame 118, and then fixed on the fixed frame 111. Movable frame 1 via fixed motor-119 and pitch screw 120
A light-shielding device is constituted by holding 18. FIG.
(A) shows a state where the chevron lens 113 of the first sheet 114 and the light-shielding portion 115 of the second sheet 117 face each other, and the light condensed through the chevron lens is shielded. Becomes FIG. 12B shows the first sheet 114.
Angle lens 113 and light transmitting portion 11 of the second sheet 117
In a state where 6 are opposed to each other, the light condensed through the chevron lens is transmitted, so that the light is transmitted.

According to the above construction, in the translucent state, by converging with the chevron lens, all the light to be poured into the first sheet can be taken into the translucent portion, and the first sheet It can be made brighter than the configuration in which the light shielding portion is provided. It should be noted that, in the above, a pulley or a hinge may be attached to the fixed frame to form a window or a door. Alternatively, it may be a window of a car or a sun roof.

[0030]

As described above, according to the present invention, the translucent material is opposed to the glass at a constant interval according to the glass frame shape of the window or door, and the periphery thereof is brought into contact with the glass. As described above, by constructing the cross section into a substantially U-shape and fixing it to the glass or the glass frame, the single-glazing window can be easily made into a multi-layer structure. Also, because there is an air layer sealed between the glass and the heat insulating device formed in a substantially U shape,
The heat transmission rate is reduced, and the energy consumption of heating and cooling can be reduced. In addition, one of two facing sheets, in which a light-shielding portion (light-reducing portion) and a light-transmitting portion are alternately arranged at a fixed pitch, is fixed and the other is held so as to be movable in the pitch direction. By moving the sheet in the pitch direction by about a half pitch, it is possible to instantaneously switch from light transmission to light shielding (dimming) or light shielding to light transmission. Further, the first sheet having the lens formed thereon is fixed, and the second sheet having the light-shielding portion (light-reducing portion) and the light-transmitting portion having the same pitch is moved in the pitch direction so as to face the first sheet. With the configuration held as possible, by moving the second sheet by about a half pitch in the pitch direction, it is possible to instantaneously switch from light transmission to light shielding (dimming) or light shielding to light transmission.
In the translucent state, the light is condensed by the lens, so the amount of light increases. Furthermore, the configuration in which the movement of the sheet is performed electrically allows the shading device to be operated from a remote place and the shading amount to be arbitrarily adjusted.
