Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
1 to 3 show an embodiment of a sunshade device of the present invention.

  As shown in FIGS. 1 and 2, the awning device 1 of this embodiment is installed on a veranda 30 in a building such as a house.

  In the veranda 30, an opening 34 that is open to the external space is formed between the outer waist wall 32 and the outer edge of the ceiling 33. Moreover, it is comprised so that the exterior can be looked at from the room through the window 31 which can be opened and closed, and it can fully perform indoor lighting, ventilation, etc. as needed.

  The awning device 1 of the present embodiment includes a storage part 2 installed along the outer edge of the ceiling part 33 or eaves of the veranda 30 adjacent to the interior of the room, and a storage part 2 that can be freely inserted and removed from the storage part 2 downward. A shade member 3 is provided. The awning device 1 is installed inside the storage portion 2 and includes a drive shaft 4 that can wind and unwind the shade member 3. Further, a control means 10 is provided for controlling the drive shaft 4 so as to unwind the shade member 3 and lower it from the storage portion 2, and to control the drive shaft 4 so as to store the shade member 3 in the take-up storage portion 2. Yes. The awning device 1 is characterized in that the shade member 3 can be switched between a light-blocking state in which the outside light 15 is blocked and a daylighting state in which the outside light 15 is refracted or reflected and led into the room.

  As shown in FIGS. 1 and 2, the storage portion 2 of the sunshade device 1 is installed on the ceiling portion 33 of the veranda 30 along the outer edge thereof. In addition, as long as it is a part of an outer edge, you may be provided in the part which approached the window 31 side a little. The storage portion 2 has a long-axis shape having a cavity that can store the shade member 3 and the drive shaft 4. The longitudinal direction is substantially equal to the waist wall 32 of the veranda 30 so that the entire opening 34 of the veranda 30 can be covered with the shade member 3. Of course, a part of the opening 34 of the veranda 30 may be covered with the shade member 3.

  The storage unit 2 uses a solar battery or a storage battery as a power source for the awning device 1, so that it can be attached to the ceiling portion 33 of the veranda 30 using a fixing bracket or the like without performing wiring work such as introducing a power cord into the room. It can be easily retrofitted.

  The shade member 3 is housed in the housing portion 2 so as to be able to be inserted and removed from the housing portion 2 downward. As shown in FIG. 3, the shade member 3 includes a liquid crystal shutter 20 and a prism 22.

  The liquid crystal shutter 20 only needs to be flexible enough to be wound around the drive shaft 4, and a liquid crystal emulsion and a good conductor are extended on a plastic sheet, or a polymer-dispersed liquid crystal film is used as an electrode film. Examples include a sandwiched structure. The transmission state and the scattering state can be electrically switched by turning on and off the voltage applied to the liquid crystal shutter 20. In addition, by installing a controller and modulating the voltage applied to the liquid crystal shutter 20, it is possible to continuously change from the transmission state to the scattering state and to switch continuously from the lighting state to the light shielding state.

  The prism 22 only needs to be flexible so that the shade member 3 can be wound around the drive shaft 4. For example, the prism 22 is a flexible prism having a fine pattern on the surface where prism angles are arranged on a plane. A sheet etc. are mentioned.

  The liquid crystal shutter 20 and the sheet of the prism 22 are bonded together to form the shade member 3 so that the liquid crystal shutter 20 is an outdoor side surface and the prism 22 sheet is an indoor side surface.

  As shown in FIG. 3A, the shade member 3 is brought into a transmission state in which the external light 15 is transmitted and is in a light extraction state in which the external light 15 is refracted or reflected and guided into the room by electrical switching of the liquid crystal shutter 20. be able to. At this time, the external light 15 passes through the liquid crystal shutter 20 on the outdoor side surface, and is refracted or reflected by the prism 22 to be guided indoors. Thereby, light and heat from the outside can be taken into the room.

  The shade member 3 can be in a scattering state in which the external light 15 is scattered and in a light-shielding state in which the external light 15 is blocked by electrical switching of the liquid crystal shutter 20 as shown in FIG. At this time, the outside light 15 is scattered by the liquid crystal shutter 20 on the surface on the outdoor side, and some of the scattered light is transmitted, and is refracted or reflected by the prism 22 and guided to the room. That is, the light shielding state is such that the outside light 15 slightly leaks into the room. As a result, light and heat from the outside can be blocked without being taken into the room.

  The shade member 3 has a long band shape, and the width of the shade member 3 in the short direction is substantially equal to the longitudinal direction of the storage portion 2. In the longitudinal direction of the shade member 3, one end thereof is connected to the drive shaft 4, and a weight is provided at the other end. The shade member 3 is unwound downward from the storage portion 2 by the weight of the weight due to the rotation of the drive shaft 4 based on the signal from the control means 10.

  The drive shaft 4 is installed inside the storage portion 2 so that the shade member 3 can be wound and unwound. The drive shaft 4 as a rotation shaft that becomes the core of the shade member 3 includes a motor (not shown). A signal is output from the control means 10 by a user's panel operation, etc., and the motor of the drive shaft 4 is started to drive the shade member 3 up and down. That is, the drive shaft 4 is installed inside the storage portion 2 so that the shade member 3 can be switched between a storage posture in which the shade member 3 is wound around the drive shaft 4 and a protective posture in which the shade member 3 is unwound from the storage portion 2. Yes.

  The control means 10 inputs / outputs signals to / from the motor of the drive shaft 4 as follows by user panel operation or the like.

  In the present embodiment, an arithmetic control device is built in the awning device 1 as the control means 10. As a power source for the awning device 1 such as an arithmetic control device and a motor of the drive shaft 4, a solar battery or a storage battery is used, so that a power supply cord is not introduced into the room, and a fixing bracket is used. Can be easily retrofitted to the ceiling 33 of the veranda 30. Of course, a commercial power supply can also be used.

  The arithmetic and control unit may include hardware similar to a general-purpose computer such as a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The CPU can obtain the output of the panel operation of the user or give a command signal to the motor of the drive shaft 4.

  Further, the ROM stores a program and setting data for realizing the function of the awning device 1 in the present embodiment using an arithmetic control device. As this ROM, an electrically rewritable flash memory can be used. The CPU of the arithmetic and control unit reads the program from the ROM to the RAM at the start-up. And according to the instruction | command and setting data of the program, the function of the awning apparatus 1 in this embodiment is implement | achieved.

  The arithmetic and control unit functions as the control means 10 by following the command and setting data of the program. The control means 10 controls the motor of the drive shaft 4 to unwind the shade member 3 and house the shade member 3 in accordance with the panel operation of the user.

  Further, the awning device 1 of the present embodiment includes a storage unit capable of setting a descending length of the shade member 3 from the storage unit 2. The control means 10 controls the drive shaft 4 so that the shade member 3 is unwound by the descending length set in the storage means by the user's panel operation or the like. This storage means may be a ROM or RAM as described above.

  That is, the storage means can store an electrical signal corresponding to an arbitrary descending length according to a user setting. The shade member 3 is driven downward by a stored amount by the user's panel operation or the like. The descending length of the shade member 3 is rewritably stored in the storage means as an electrical signal corresponding to the rotational speed of the drive shaft 4 and the like.

  The user sets an operation for winding and unwinding the shade member 3, an operation for electrically switching the liquid crystal shutter 20 of the shade member 3, and a lowering length of the shade member 3 from the storage portion 2 in the storage unit. The user may perform the operation with an operation panel provided in the storage unit 2. Alternatively, an operation panel may be separately installed in the room or the like, and may be performed wirelessly or by wire.

  The sunshade device 1 of the present embodiment having the above configuration is used as follows.

  When the solar radiation is strong, such as in summer, the waist wall 32 of the veranda 30 is obtained by switching the shade member 3 to a protective posture in a light-shielded state by a user's switch operation or the like in order to shield light and heat from the outside to the room. And the opening 34 between the ceiling part 33 is closed.

  First, an input signal by a user's panel operation is input to the control means 10. The control means 10 outputs a signal to the motor of the drive shaft 4. Then, the drive shaft 4 is rotated by the motor, and the shade member 3 is unwound and lowered from the storage portion 2. More specifically, the awning device 1 includes storage means capable of setting the descending length of the shade member 3 from the storage portion 2 as described above. The control means 10 outputs a signal to the motor of the drive shaft 4 so that the shade member 3 is unwound by the descending length set in the storage means by the user's panel operation. After rotating as set in the storage means, the control means 10 stops the motor of the drive shaft 4.

  At this time, as shown in FIG. 2B and FIG. 3B, the liquid crystal shutter 20 of the shade member 3 is in a scattering state that scatters the external light 15 and blocks the external light 15 by the user's panel operation. It is electrically switched to the light shielding state. The outside light 15 is scattered by the liquid crystal shutter 20 on the surface on the outdoor side, and some of the scattered light is transmitted, and is refracted or reflected by the prism 22 and guided to the room. That is, the light shielding state is such that the outside light 15 slightly leaks into the room. As a result, light and heat from the outside can be blocked without being taken into the room.

  Thereafter, when the solar radiation becomes weak, the opening 34 between the waist wall 32 and the ceiling 33 of the veranda 30 is opened by switching the shade member 3 to the storage posture.

  First, an input signal by a user's panel operation is input to the control means 10. The control means 10 outputs a signal to the motor of the drive shaft 4, and then the drive shaft 4 is rotated by the motor and the shade member 3 is stored in the take-up storage unit 2. More specifically, the control means 10 outputs a signal to the motor of the drive shaft 4 so as to wind up the shade member 3 by the descending length set in the storage means. After rotating as set in the storage means, the control means 10 stops the motor of the drive shaft 4.

  On the other hand, when the solar radiation is weak, such as in winter, the waist wall 32 of the veranda 30 is obtained by switching the shade member 3 to the protective posture in the daylighting state by the user's panel operation in order to collect light and heat from the outside into the room. And the opening 34 between the ceiling part 33 is closed.

  In other words, the liquid crystal shutter 20 is electrically switched by the user's panel operation, and as shown in FIGS. 2A and 3A, the external light 15 is transmitted, and the external light 15 is changed. It can be in a daylighting state where it is refracted or reflected and led into the room. At this time, the external light 15 passes through the liquid crystal shutter 20 on the outdoor side surface, and is refracted or reflected by the prism 22 to be guided indoors. Thereby, light and heat from the outside can be taken into the room.

  Thereafter, the opening 34 between the waist wall 32 and the ceiling 33 of the veranda 30 is opened by switching the shade member 3 to the storage position in accordance with changes in the weather, sunset, or the like.

  In the shade device 1 of the present embodiment, the shade member 3 may have a function of ultraviolet cut, infrared cut, or both.

  The ultraviolet cut can be performed by laminating an ultraviolet cut film on the shade member 3 or adding an ultraviolet absorbent to the liquid crystal shutter 20 or the like. Thereby, ultraviolet rays can be cut out of the outside light 15 entering the room, the amount of ultraviolet rays exposed to the occupants in the room can be reduced, and adverse effects of the ultraviolet rays on the human body such as health can be reduced.

  The infrared cut can be performed by laminating an infrared cut film on the shade member 3. Thereby, infrared rays can be cut out of the outside light 15 entering the room, and it is possible to take in the light while taking in only the light and keeping the heat shielding effect.

  The awning device 1 of the present embodiment may be configured as follows. That is, the solar radiation amount detecting means for detecting the solar radiation amount may be provided, and the control means 10 may be configured to switch between the light shielding state and the daylighting state according to the solar radiation amount detected by the solar radiation amount detecting means.

  The solar radiation amount detecting means is not particularly limited as long as it is a sensor capable of detecting the solar radiation amount, and can be installed in the storage unit 2.

  For example, a threshold value for the amount of solar radiation is stored in advance in the ROM as setting data. When the shade member 3 is unwound from the storage unit 2, the CPU compares the amount of solar radiation indicated by the output of the solar radiation amount detecting means with a threshold value in a timely manner.

  If the amount of solar radiation is less than or equal to the threshold value, the CPU enters a transmission state that transmits the external light 15 and refracts or reflects the external light 15 in the room, as shown in FIGS. 2 (a) and 3 (a). It is determined whether or not it is necessary to electrically switch the liquid crystal shutter 20 so as to obtain a led lighting state. As shown in FIGS. 2B and 3B, when the liquid crystal shutter 20 is in a light shielding state that blocks the external light 15, it is determined that the liquid crystal shutter 20 needs to be electrically switched. Based on this determination, light and heat from the outside can be taken into the room by setting the daylighting state shown in FIGS. 2 (a) and 3 (a). On the other hand, when the liquid crystal shutter 20 is in the daylighting state shown in FIGS. 2A and 3A, it is determined that electrical switching of the liquid crystal shutter 20 is not necessary.

  When the amount of solar radiation exceeds the threshold value, the CPU electrically controls the liquid crystal shutter 20 so as to block the external light 15 as shown in FIGS. 2 (b) and 3 (b). It is determined whether switching is necessary. When the liquid crystal shutter 20 is in the daylighting state shown in FIGS. 2A and 3A, it is determined that electrical switching of the liquid crystal shutter 20 is necessary. Based on this determination, light and heat from the outside can be blocked by setting the light shielding state shown in FIGS. 2B and 3B. When the liquid crystal shutter 20 is in the light shielding state shown in FIG. 2B and FIG. 3B, it is determined that it is not necessary to electrically switch the liquid crystal shutter 20.

  By providing the solar radiation amount detecting means in the awning device 1 in this way, automatic shading and daylighting according to the weather are possible.

  According to the sunshade device 1 of the present embodiment described above, the shade member 3 can switch between a light shielding state that blocks the outside light 15 and a daylighting state that refracts or reflects the outside light 15 and guides it into the room. Throughout the year, the light and heat from outside the room can be kept comfortable.

  Moreover, when the shade member 3 has the function of ultraviolet ray cut, infrared ray cut off, or both, the ultraviolet ray into the room can be reduced by cutting off the ultraviolet ray or infrared ray and collecting only the necessary light. It is possible to perform daylighting while maintaining the heat shielding effect. Thereby, the shade member 3 can be made suitable for the lighting condition, and light and heat from outside in the room can be kept comfortable throughout the year.

Moreover, it is provided with the solar radiation amount detection means which detects solar radiation amount, and the control means 10 is set as the structure which switches a light-shielding state and a lighting state according to the solar radiation amount which the solar radiation amount detection means detected, according to solar radiation amount Automatic shading and daylighting are possible.
