Detailed Description
Hereinafter, a horizontal blind according to an embodiment will be described with reference to the drawings.
[ first embodiment ]
As shown in fig. 1 and 2, the horizontal blind 10 includes: a head box (head box)11 attached to an attachment portion of a ceiling, a window frame, a curtain box, or the like, and a plurality of blades (flat) 12 serving as a shade for shielding solar radiation.
Further, the horizontal louver 10 further includes: three direction control ropes (cord) 13 as support members hanging from the upper beam 11 and supporting the plurality of blades 12 so as to be able to adjust their inclinations, a lower beam (bottom rail)14 positioned below the lowermost blade 12, and a first lift rope 15a and a second lift rope 15b hanging from the upper beam 11 and having one end connected to the lower beam 14.
Further, a first elevation cord 15a and a direction control cord 13 are disposed at both ends of the blade 12 in the longitudinal direction, respectively, and a second elevation cord 15b and a direction control cord 13 are disposed at an intermediate portion of the blade 12 in the longitudinal direction.
The blade 12 is formed in an elongated rectangular thin plate shape, and a lower surface as one surface of the blade 12 is formed of an arc-shaped concave surface, and an upper surface as the other surface of the blade 12 is formed of an arc-shaped convex surface. The plurality of blades 12 are configured as follows: a plurality of blades 12 are arranged in the vertical direction, which is the height direction of the horizontal blind 10, and the tilt of the blades 12 can be adjusted by the direction control cord 13 hanging from the upper beam 11. A lower beam 14 having substantially the same length as the blade 12 is disposed below the lowermost blade 12.
When the plurality of blades 12 are kept in the lowered state, the lower beam 14 functions as a weight member, and the lower beam 14 is formed of a metal material such as SECC. The lower beam 14 has substantially the same length in the longitudinal direction and width in the width direction as the blades 12, and when the lower beam 14 is pulled up, a plurality of blades 12 are stacked above the lower beam 14. The direction control rope 13 is connected to the lower beam 14. First lift cord 15a and second lift cord 15b drawn from upper beam 11 are connected to lower beam 14, and lower beam 14 is suspended from upper beam 11 by first lift cord 15a and second lift cord 15 b.
In the plurality of blades 12 constituting the blade group, rectangular through holes 21 are disposed in the middle portions in the front-rear direction, which is the width direction, at both ends in the longitudinal direction of the blades 12, and the rectangular through holes 21 have their long sides extending in the width direction. Further, a second lift cord 15b is disposed at a side edge portion of the longitudinal direction intermediate portion of the blade 12, the side edge portion facing in the front-rear direction of the blade 12. The blade 12 is not formed with a through hole through which the second lift cord 15b is inserted. By not forming the through-hole in the intermediate portion in the longitudinal direction of the blade 12, high light-shielding performance can be ensured.
An inclined rod (tilt pole)18 as an operation portion for raising and lowering the lower beam 14 and a balancer (equalizer) 19 provided at a distal end portion of the inclined rod 18 are provided at a position near one end portion in the longitudinal direction of the upper beam 11. The tilt lever 18 is constituted by: when the tilt lever 18 is rotated left and right, the vertical lines of the direction control cords 13 are raised or lowered in opposite directions based on the rotation, thereby tilting the blades 12. The blades 12 can be turned by rotating the tilt lever 18 left and right, and the fully closed state and the fully open state can be switched. The balancer 19 is pulled downward, whereby the lower beam 14 and the blade 12 can be raised, and the pulling of the balancer 19 is stopped, whereby the lower beam 14 and the blade 12 can be stopped in the middle of the raising. When the lower beam 14 is raised, the plurality of blades 12 are stacked above the lower beam 14 in order from the blade close to the lower beam 14 as the lower beam 14 is raised. Further, when the blade 12 is lowered, the balancer 19 is slightly pulled downward and then loosened, and when the blade is stopped in the middle, the balancer 19 is pulled again, whereby the lowering of the lower beam 14 can be stopped. When the lower beam 14 is lowered, and the plurality of blades 12 are also lowered together with the lowering of the lower beam 14.
As shown in fig. 3, the blade 12 includes: a substrate 31, a solar light reflecting layer 32 provided on the convex surface 31a of the substrate 31, and an infrared light reflecting layer 33 provided on the concave surface 31b of the substrate 31.
The base material 31 is formed of a synthetic resin plate, a metal plate such as aluminum or stainless steel, or the like, and is formed of a light-shielding material. Further, the base material 31 may be formed of a fire-retardant material or a wood plate. The cross section of the base material 31 is arc-shaped, and the surfaces of the base material 31 facing each other are a convex surface 31a and a concave surface 31 b. In the state when the blade 12 is shielding, the convex surface 31a faces the outdoor side and the concave surface 31b faces the indoor side. When the blades 12 are in the state of being shielded, the upper blades 12 are arranged so that the upper blades 12 are overlapped with the lower blades when viewed from the outdoor side, and thus, the solar radiation is less likely to enter the room through the gaps between the blades 12. Aluminum is used for the base material 31. A primer layer (primer layer)35 is provided on the substrate 31, and the primer layer 35 serves as a base for the adhesive layer 34 of the infrared-reflective layer 33.
The sunlight reflecting layer 32 reflects sunlight in a range from visible light to near infrared rays (wavelength of about 380nm to 2500 nm). The solar light reflecting layer 32 is formed by applying a heat insulating coating material (paint) containing a solar light reflecting component such as aluminum by a coating device such as a roll coater and drying the coating material. As an example, the solar light reflecting layer 32 is formed by: the thickness of the film on the convex surface 31a of the substrate 31 is about 10 μm. Further, since the thermal barrier coating material contains a color material such as a pigment, the convex surface of the blade 12 can be colored in various colors by changing the color material. The sunlight reflecting layer 32 is provided on the convex surface 31a facing the outdoor side in a state where the sunlight can be made incident into the room in a small amount in the normal shade, and can reflect more sunlight to the outdoor side.
The infrared-ray reflective layer 33 is a layer that reflects most of infrared rays, particularly far infrared rays (wavelength of about 10 to 20 μm). In other words, the infrared reflective layer 33 is an infrared low-emissivity layer that emits infrared light, particularly far infrared light, at a low level with respect to the substrate 31. Here, the emission of aluminum with respect to the base material 31 is low. The infrared reflective layer 33 transmits sunlight, for example. For example, the infrared reflection layer 33 is formed of a metal thin film containing silver or a metal oxide (zinc oxide, tin oxide, or the like), for example, Low-e (Low emissivity). The infrared reflection layer 33 is bonded to the base material 31 via the adhesive layer 34. As an example, the infrared reflecting layer 33 is provided on the concave surface 31b of the base material 31 by thermal transfer (thermal transfer).
The sheet (sheet) for placing the infrared-ray reflective layer 33 on the concave surface 31b is a thermal transfer sheet, a release layer is provided on the release sheet, the infrared-ray reflective layer 33 is provided on the release layer, and the adhesive layer 34 is further provided on the infrared-ray reflective layer 33. Then, the adhesive layer 34 is bonded to the concave surface 31b, and then the thermal transfer sheet is pressed and heated against the concave surface 31b, whereby the infrared ray reflective layer 33 is fixed to the concave surface 31b via the adhesive layer 34. Thereafter, the release sheet is peeled from the infrared ray reflective layer 33 at the peeling layer. Since the infrared reflective layer 33 is a thin metal film and is formed to have a thickness to a degree that the ground color of the base material 31 slightly transmits, the color of the surface of the infrared reflective layer 33 can be changed by changing the ground color of the concave surface 31 b. For example, the adhesive layer 34 to which the infrared reflection layer 33 is adhered is formed to have a thickness of about 10 to 20 μm.
The blade 12 as described above is manufactured by providing the solar light reflecting layer 32 on the convex surface 31a of the base 31 and then thermally transferring the adhesive layer 34 and the infrared ray reflecting layer 33 onto the concave surface 31 b.
Next, the operation of the horizontal blind 10 having the above-described structure will be described.
The horizontal blind 10 is attached to a sash to be attached: in a state where the lower beam 14 is lowered, the lower beam 14 is positioned at a lower side of the lower frame of the window frame. In addition, in the horizontal blind 10, when the balancer 19 is pulled downward when the vanes 12 and the underbeam 14 are raised, the plurality of vanes 12 are stacked above the underbeam 14 in order from the vane close to the underbeam 14, and the underbeam 14 is raised. When the blade 12 and the lower beam 14 are lowered, if the balancer 19 is slightly pulled downward and loosened, the lower beam 14 is lowered, and the plurality of blades 12 are also lowered together with the lowering of the lower beam 14. Further, by rotating the tilt lever 18, each blade 12 is tilted in the normal shielding direction or the reverse shielding direction based on the direction of the rotation.
As shown in fig. 4, in the vicinity of a house or the like, the daytime is in the following environment.
Although a part of solar radiation 111 is absorbed by window glass 101, most of solar radiation 111 passes through window glass 101, is reflected by vanes 103 of horizontal louver 102, and then passes through window glass 101 again to be emitted to the outside (2) of room 100. In fig. 4, horizontal louver 102 is a conventional horizontal louver, and a sunlight reflecting layer is provided only on one surface of blade 103.
A part of the solar radiation 111 having passed through the window glass 101 is absorbed by the blade 103 and converted into heat energy, thereby heating the blade 103 (3).
In addition, a part of the solar radiation 111 passes through the gap (4) between the vanes 103.
The blade 103 heated by solar radiation radiates radiant heat (5) derived from far infrared rays.
In general, an air conditioner such as an air conditioner is prepared in room 100, and when air between window glass 101 and horizontal louver 102 is heated, convection is generated due to a temperature difference between a space between window glass 101 and horizontal louver 102 and an indoor space, and convection heat flows into a room (6).
That is, in room 100, the space inside of horizontal louver 102 is heated by solar radiation (4) transmitted through the gaps between vanes 103, radiant heat (5) from far infrared rays from vanes 103, and convection heat (6) between window glass 101 and horizontal louver 102.
As shown in fig. 5, in the daytime in summer or the like, the horizontal blind 10 of the present invention is applied, preferably: in a state where the blade 12 is lowered, the blade 12 is tilted to a positive shielding state. This is so because: in the forward shielding state, the solar radiation is less likely to be incident into the room from the gap between the adjacent blades 12 than in the reverse shielding state. In fig. 5 and 6, the adhesive layer 34 and the primer layer 35 are not shown.
In this case, the solar light reflecting layer 32 on the convex surface 31a faces the window glass 101, and the infrared light reflecting layer 33 on the concave surface 31b faces the indoor side. Since the sunlight reflecting layer 32 is provided on the surface of the blade 12 on the window glass 101 side (outdoor side), the solar reflectance is high, and most of the solar radiation 111 can be reflected, whereby the temperature rise (11) of the blade 12 can be suppressed.
The blade 12 radiates the radiant heat 112 after being heated by a part of the solar radiation 111, but since the infrared reflecting layer 33 is present, most of the radiant heat is radiated to the window glass 101 side (outdoor side), and thus the radiation in the indoor side is suppressed (12).
Further, in room 100 at a temperature close to room temperature (about 25 ℃), radiant heat 113 originating from far infrared rays is radiated, but the radiant heat 113 is reflected by infrared ray reflection layer 33, and leakage of indoor heat to the outside (13) can be suppressed.
As shown in fig. 6, during the daytime in winter or the like, it is preferable that: in a state where the blade 12 is lowered, the blade 12 is tilted to a reverse shielding state. In this case, the infrared reflective layer 33 on the concave surface 31b faces the window glass 101, and the solar reflective layer 32 on the convex surface 31a faces the indoor side. Most of the solar radiation 111 from the window glass 101 passes through the infrared reflecting layer 33, heats the blade 12, radiates the radiant heat 114 to the indoor side via the sunlight reflecting layer 32, and heats the indoor space (14). At this time, the infrared reflective layer 33 suppresses the radiant heat 114 from being radiated to the outdoor side.
In addition, the state of fig. 5 is preferable when there is no sunshine or night in the daytime in winter because of a cloudy day or the like. This is because: far infrared rays emitted from a room can be reflected by the infrared reflection layer 33 facing the indoor side, and heat leakage from the indoor side to the outdoor side (13) can be suppressed.
According to the horizontal blind 10 as described above, the following effects can be obtained.
(1) The blade 12 is constituted by: since the infrared reflection layer 33 is provided on the concave surface 31b of the base material 31 via the adhesive layer 34, the blade 12 can be made thinner as compared with a case where a film provided with the infrared reflection layer 33 is bonded to the base material 31 as in the prior art. Accordingly, the weight of the blades 12, and hence the weight of the horizontal blind 10, can be reduced. Further, as the weight of the blade 12 is reduced, the operating force when the blade 12 is raised or lowered is reduced, and in this respect, the operability can be improved. Further, in the horizontal blind 10, the folded dimension when the lower beam 14 is raised in the direction toward the upper beam 11 can be reduced. This can improve the design of the horizontal blind 10.
(2) Since the infrared reflection layer 33 is provided by thermal transfer, the production efficiency can be improved. As an example thereof, when the infrared reflection layer 33 is provided by using a paint, a drying time of the paint is required, but when the infrared reflection layer 33 is provided by thermal transfer, a time corresponding to the drying time of the paint can be shortened, and the production efficiency can be improved.
[ second embodiment ]
As shown in FIG. 7, the blade 12 may also be provided with an anti-fouling System 36, located above the solar-reflective layer 32. The antifouling layer 36 may be formed by coating (coating) a fluororesin, or may be formed by providing titanium oxide on the upper layer of the base layer. This can prevent the solar light reflecting layer 32 from being stained.
Further, the blade 12 may be provided with a protective layer 37 on the infrared-reflective layer 33. The protective layer 37 may be an oxidation prevention layer for preventing oxidation of the infrared reflection layer 33, or may be a hard coat layer having a scratch prevention function. As an example of the protective layer 37, a release layer of a thermal transfer sheet may be used. The protective layer 37 may be formed by further coating paint on the upper layer of the release layer.
[ third embodiment ]
As shown in fig. 8, the blade 12 may also be configured to: the infrared reflective layer 33 is not thermally transferred, but is formed by directly applying a coating material (paint) containing an infrared reflective material onto the concave surface 31b by a coating device such as a roll coater and drying the coating material. In this case, the adhesive layer 34 can be omitted, and further, the blade 12 can be made thinner or lighter. The undercoat layer 35 may be omitted or may be made of a material suitable for coating. Further, when the infrared reflection layer 33 is formed of a material suitable for paint, a color material can be mixed, and thus the degree of freedom in designing the infrared reflection layer can be increased.
The horizontal blind 10 as described above can be modified as appropriate as described below.
The infrared reflection layer 33 is made of a metal thin film and thus has a metallic luster. When the infrared ray reflection layer 33 faces the room, the condition in the room is reflected on the surface of the blade 12. Therefore, the infrared reflective layer 33 may be formed by performing diffuse reflection processing such as matte processing on the surface thereof to form a non-directional matte surface as a processed surface of the diffuse reflection processing. In the second embodiment, the diffuse reflection processing may be performed on the infrared-ray reflective layer 33 or on the protective layer 37. This improves the design of the horizontal blind 10, and the horizontal blind 10 can be easily used.
The solar light reflection layer 32 is not limited to one provided by applying a heat insulating coating material (paint). As an example, a film provided with the solar light reflecting layer 32 may be bonded to the base material 31.
The infrared-ray reflective layer 33 is not limited to the one provided by thermal transfer as long as it is provided on the base material 31 via the adhesive layer 34.
The blade 12 may be a flat plate having both flat surfaces, instead of having a convex and concave shape.
The blade 12 may be provided with a solar light reflecting layer 32 on the concave surface and an infrared reflecting layer 33 on the convex surface.
The shade such as the blade 12 may be provided with the infrared reflecting layer 33 on at least one surface thereof, and the sunlight reflecting layer 32 on the other surface may be omitted.
The metal thin film of the infrared reflective layer 33 may be formed directly on the substrate 31 by a sputtering method or a CVD method.
As the lifting member, a lifting belt may be used in addition to the lifting rope. In addition, the direction control cord may be a direction control tape.
The horizontal blind may also be adapted for use in an electric horizontal blind system. An electric blind system is provided with: an electric blind for electrically raising, lowering, or tilting the vanes 12 using a motor or the like as a drive source, a sensor for detecting solar radiation provided outdoors or the like, and a control device for controlling the tilting, raising, or lowering of the vanes 12.
The control device can perform setting in summer and winter, and perform control to tilt the blades 12 as shown in fig. 5 during daytime in summer (when solar radiation is detected by the sensor in summer). In addition, during the daytime in winter or the like (when insolation is detected by the sensor in winter), control is performed to tilt the blades 12 as shown in fig. 6. When the louver 12 is applied to the electric blind system, the tilt of the louver 12 can be automatically controlled according to the solar radiation situation, and the energy saving effect can be improved.
The invention can also be applied to vertical blades of a vertical blind. In this case, the infrared reflecting layer may be provided on at least one surface of the vertical blade which is a shield suspended from the support member in the upper beam.
Further, the present invention can also be applied to a roll screen or a pleated screen. In this case, the support member suspended from the upper beam raises or lowers the curtain cloth such as a cloth serving as a screen. In addition, an infrared reflecting layer may be provided on one surface of the curtain fabric. Preferably: the curtain cloth has fireproof performance.
Further, the blade may be applied to a louver (louver) or the like assembled in parallel with a frame as a support member with a gap therebetween.
The solar radiation shielding device such as a horizontal louver may be disposed between the inner window and the outer window. The light-transmitting separator may be disposed inside the light-transmitting separator.
