Description

  The present invention relates to a light shielding device that shields a window provided in a fixed structure such as a building or a moving structure such as a ship. For example, when shielding or blinding a window in a bathroom, a toilet, or a bathroom Can be used for etc.

  Conventionally, a window provided in various structures such as buildings has been installed with a light shielding device using a blind or a roll curtain formed by connecting a plurality of slats in order to shield and blind the light. Yes. These shades such as blinds and roll curtains are usually housed in the upper part of the window when not in use, and when they are shielded or blindfolded, they are gradually lowered from the top to the shaded area (the blinded area). It has come to expand. In addition, there is a configuration in which the light shield is closed from the left and right sides toward the center. The light shielding device includes a device that can manually operate a blind, a roll curtain, and the like, and an electric device that uses a motor.

  As a technique related to the present invention, for example, an electric blind capable of opening / closing a blind and adjusting an angle with a single drive motor is known. It has a conventional configuration in which the blind is lowered from the bottom (see Patent Document 1).

JP 2003-301673 A

  However, in the conventional light-shielding device using the light-shielding body such as the blind or the roll curtain, the light-shielding body is closed when closing both the manual type and the electric type, that is, when the light-shielding range (the blinding range) is expanded. Is moved from the upper side to the lower side or from the left and right sides toward the center, so in the former case, the light shielding range is expanded from the upper part of the window opening, and the lower part of the window opening is In the latter case, the light shielding area extends from the left and right sides of the window opening, and the center of the window opening is finally closed.

  For this reason, focusing on the last part of the window opening that is blocked, the person inside the window wants to conceal himself in order to block the inconvenient line of sight from the outside of the window. In order to completely hide the portion, it is often necessary to end up in a fully closed state, that is, a state in which the entire window opening is covered. If the light-shielding device is fully closed, natural light does not enter the space inside the window, and the room will be dark unless an electric lamp is attached. Therefore, it is convenient if there is a light-shielding device that can appropriately hide a portion that needs to be blindfolded by a person inside the window and can perform appropriate daylighting.

  The objective of this invention is providing the light-shielding apparatus which can implement | achieve appropriate blindfold and appropriate lighting simultaneously.

  The present invention is a light-shielding device that shields a window provided in a structure, and includes a rectangular frame that is attached around the window, a light-shielding body that shields light by covering at least a part of the opening of the window, and a frame. A storage part provided in the lower part of the body for storing the light shielding body, left and right wires connected to the left and right ends in a state of hanging the left and right ends of the upper edge of the light shielding body, When expanding the light shielding range of the left and right reels for winding the wire and the window, the upper edge of the light shielding body is lifted upward by rotating the reel in the direction of winding the wire, and the light shielding body is accommodated When gradually reducing the light-shielding range of the window, the reel is rotated in the direction of feeding the wire to lower the upper edge of the light-shielding body downward so that the light-shielding body is gradually housed in the housing part. With a winding motor And it is characterized in and.

Here, the “window provided in the structure” is a window provided mainly in a fixed structure such as a building such as a bathroom, a toilet, and a bathroom, but is not limited thereto. , Camper windows (however, it is a window in the living room, not a window next to the driver's seat or passenger seat), windows provided on moving structures such as buses, trains, ships, airplanes, etc. included. Moreover, not only the window provided in the outer peripheral wall which forms the boundary between indoor and outdoor, but also a window provided in a partition wall that partitions an indoor space such as a boundary between a living room and a bathroom, for example. In the case of a moving structure, for example, in the case of a ship, the outside of the portion corresponding to the outer peripheral wall that separates the inboard space and the outboard space is a deck and a person may walk. In addition, since there is a portion corresponding to a partition wall for partitioning a passage through which people come and go and a cabin in the space in the ship, there are windows that can exhibit the functions and effects of the present invention described below.

  In such a light-shielding device of the present invention, when closing, that is, when covering the window opening and expanding the light-shielding range, the right and left wires are wound up by the winding motor and the upper edge of the light-shielding body is moved upward. The light shielding body is gradually pulled upward from the storage part provided at the lower part of the frame body by pulling it up, so that it is possible to perform desired blindfolding for those who have the upper edge of the light shielding body inside the window. If the winding motor is stopped when it reaches an appropriate position, the lower part of the window opening is covered with the light shielding body to achieve appropriate blinding, and the upper part of the window opening is shielded from light ( A portion that is not blindfolded is formed, and appropriate daylighting from the top is realized.

  For this reason, it is possible to eliminate the inconvenience that, as a result of performing necessary blindfolding as in the case of a conventional light-shielding device, daylighting cannot be performed at all and the room is darkened, thereby achieving the object.

  More specifically, when the light shield is a blind formed by connecting a plurality of slats, the following configuration is desirable. In other words, in the above-described light shielding device, the light shielding body is a blind formed by connecting a plurality of slats in parallel by string-like members, and is attached to the left and right ends of the uppermost slat among the plurality of slats. By rotating either one of the left and right shafts of the uppermost slat and the guide rails provided on the left and right side portions of the frame to slide the left and right shafts up and down In addition to adjusting the inclination of the uppermost slat, a tilt adjusting motor that adjusts the inclination of other slats out of the storage portion among the plurality of slats, and the right and left of the uppermost slat Left and right pulleys attached to the shaft, respectively, and the left and right wires suspend the left and right shafts of the uppermost slats via the left and right pulleys. The rotor side of the tilt adjustment motor is fixed to one of the left and right shafts of the uppermost slat and integrated with the uppermost slat. And the stator side of the tilt adjusting motor is integrated with the case of the tilt adjusting motor or a member fixed to the case, and is configured to slide up and down by the guide rail. Is desirable.

  In this way, when the shade is used as a blind and the slat inclination is adjusted by the inclination adjustment motor, the slat inclination can be adjusted electrically by the inclination adjustment motor. It becomes possible to reduce the labor.

  In addition, since the case of the tilt adjustment motor or the member fixed to the case is slidably guided up and down by the guide rail, the uppermost position of the tilt adjustment motor is maintained while keeping the posture of the tilt adjustment motor constant. The slats of the slats can be rotated, and stable slat inclination adjustment can be performed. In other words, the stator side of the tilt adjustment motor moves up and down along the guide rail, but the posture is maintained so as not to rotate with respect to the space. It will be transmitted reliably to the slats.

  In addition, when the light shielding body is a roll curtain, the following configuration is desirable. That is, in the above-described light-shielding device, the light-shielding body is a roll curtain that is wound and stored in the storage unit, and is used to slide up and down the left and right ends of the shaft provided at the upper edge of the roll curtain. Stores guide rails provided on the left and right sides of the frame, left and right pulleys attached to the left and right ends of the shaft provided on the upper edge of the roll curtain, and an expanded roll curtain. Rewinding springs that urge in the direction of the left and right wires, and the left and right wires hold the left and right ends of the shaft provided on the upper edge of the roll curtain via the left and right pulleys while holding the left and right ends. It is desirable that the reel is wound around.

  In this way, when the light shielding body is a roll curtain, since a rewinding spring is provided, the roll curtain which is sent out upward from the storage section provided at the lower part of the frame body is always stored in the storage section. It will be in the state pulled in the direction stored. For this reason, when the roll curtain is expanded, the light shielding posture is maintained without bending, and smooth storage without bending is realized even when the roll curtain is stored in the storage unit.

  As described above, according to the present invention, the light shielding body housed in the housing portion provided at the lower part of the frame body is expanded from the lower side to the upper side, and the movement of the light shielding body causes the window opening in order from the lower part. Since shading (blindness) is performed, if the winding motor is stopped when the upper edge of the shading body reaches an appropriate position, appropriate blinding and appropriate lighting can be realized simultaneously. There is an effect that can be done.

A storage section 40 provided in the lower part 21 of the frame 20 for storing the blind 30; and left and right wires 50 connected to the left and right ends in a state where the left and right ends of the upper edge of the blind 30 are suspended. 51, left and right reels 60 and 61 for winding the left and right wires 50 and 51, respectively, and a shaft provided on the upper part 22 of the frame body 20 to which the left and right reels 60 and 61 are fixed for raising and lowering the blind 30 The winding motor 70 that rotationally drives 62 and the left and right ends of the upper edge of the blind 30 are provided on the inner side of the left side 23 and the right side 24 of the frame 20 so as to slide up and down. A guide rail 80, 81 which is, and a tilt adjustment motor 90 for adjusting the inclination of the slats 31 of the blind 30.

  Here, the light-shielding device 10 is preferably installed in, for example, a bathroom, a toilet, a bathroom window, or the like, but is not limited thereto. Moreover, although the shape of the frame 20 is a square (square), the opening shape of the window is not limited to a square, and is arbitrary such as a triangle, a trapezoid, and a circle. Furthermore, it is preferable that the blind 30 has a size that can cover all of the window opening. However, in the fully closed state (a state where the light shielding range is maximized), the blind 30 is disposed above the window opening. The size may be such that a portion that is not shielded (blind) is generated.

  The frame 20 is configured such that a member 25 on the front surface (front surface in FIG. 1) arranged toward the indoor side is detachable, and by removing the member 25 on the front surface as shown in FIG. Maintenance of the drive mechanism including the winding motor 70 and the inclination adjusting motor 90 can be performed. The material of the frame 20 is arbitrary, such as steel (made of steel), aluminum alloy, stainless steel, wooden, and synthetic resin, as long as a certain strength for maintaining the shape can be secured.

  The blind 30 is formed by connecting a plurality of thin plate-like slats 31 in a total of four places on both the left and right ends by a string-like member 32 and arranging them in parallel. In addition, the connection location by the string-like member 32 may be provided not only at the left and right ends but also at one or a plurality of locations in the middle portion, and therefore may be a total of 6 locations, 8 locations, 10 locations, or the like. The material of the slat 31 is arbitrary as long as it has a strength capable of maintaining its surface shape to some extent, such as metal, synthetic resin, and wood. The material of the string-like member 32 is flexible so that the slats 31 can be stacked and stored in the storage portion 40 as shown in FIG. 3, and the blind 30 is provided as shown in FIG. Synthetic resin such as nylon and polypropylene, cotton, hemp, silk, metal wire, etc., as long as it has a tensile strength that does not extend greatly so that the spacing between the slats 31 can be kept constant when expanded. Is optional.

  As shown in FIG. 3, the blind 30 is not visible from the outside when it is housed in the housing portion 40 provided in the lower portion 21 of the frame body 20. That is, in FIG. 3, the front member 25 (see FIG. 1) is removed, but if the front member 25 is attached as shown in FIG. 1, it cannot be seen from the indoor side.

  As shown in FIGS. 2 to 4, left and right shafts 33 and 34 attached to the left and right ends of the uppermost slat 31 </ b> A (a member corresponding to the upper edge of the blind 30) among the plurality of slats 31 Pulleys (pulleys) 35 and 36 are rotatably attached via bearings. The left and right wires 50 and 51 are wound around the left and right reels 60 and 61 while holding the left and right shafts 33 and 34 of the uppermost slat 31A through the left and right pulleys 35 and 36, respectively. It has become. The other end of the left and right wires 50 and 51 (the end opposite to the left and right reels 60 and 61) is fixed to a member 52 provided on the upper part 22 of the frame body 20. The material of the wires 50 and 51 is preferably made of metal, but may be other than metal as long as necessary strength and durability can be secured.

  As shown in FIG. 4, the winding motor 70 rotates a shaft 62 to which the left and right reels 60 and 61 are fixed via gears 71 and 72. The winding motor 70 is a stepper motor (also referred to as a stepping motor, a step motor, or a pulse motor). The winding motor 70 is turned on / off by a remote controller (not shown), and ON / OFF control for fine rotation driving (blinds). 30 up / down control). Further, members around the winding motor 70 and the shaft 62 are accommodated in a space formed inside the upper portion 22 of the frame body 20 and are not visible from the outside. That is, FIG. 4 shows a state in which the front member 25 (see FIG. 1) is removed, but if the front member 25 is attached as shown in FIG.

  As shown in FIGS. 2 to 4, the guide rails 80, 81 provided inside the left side portion 23 and the right side portion 24 of the frame 20 are the left and right shafts attached to the left and right end portions of the uppermost slat 31 </ b> A. 33 and 34 are each slidably guided up and down.

  As shown in FIGS. 2 to 4, the inclination adjusting motor 90 is attached to a shaft 33 fixed to the left end portion of the uppermost slat 31 </ b> A. The tilt adjusting motor 90 may be attached to the shaft 34 fixed to the right end of the uppermost slat 31A. More precisely, the rotor side of the inclination adjusting motor 90 is fixed to one of the left and right shafts 33 and 34 of the uppermost slat 31A (in this embodiment, the left shaft 33). The uppermost slat 31A rotates integrally with the uppermost slat 31A. On the other hand, the stator side of the inclination adjustment motor 90 is integrated with the case of the inclination adjustment motor 90 or a member fixed to the case, and either one of the left and right guide rails 80 and 81 (this embodiment). In this case, the left guide rail 80) slides up and down.

  The tilt adjustment motor 90 is a stepper motor, similar to the winding motor 70, and is turned ON / OFF by a remote controller (not shown), and finely rotated ON / OFF control (inclination adjustment control of each slat 31). )It can be performed. The inclination angle of each slat 31 can be adjusted within a range of 180 degrees. In addition, the inclination adjusting motor 90 is accommodated in a space formed inside the left side 23 or the right side 24 (the left side 23 in the present embodiment) of the frame 20, and is not visible from the outside. . That is, in FIG. 2 to FIG. 4, the front member 25 (see FIG. 1) is removed, but if the front member 25 is attached as shown in FIG.

  In this embodiment, the raising / lowering control of the blind 30 by the winding motor 70 (opening / closing control: however, it closes when it rises and opens when it descends. .) Is performed, and the tilt adjustment motor 90 controls the tilt of each slat 31.

  First, when the operation of closing the blind 30 is performed, that is, when the blind 30 is expanded to enlarge the light shielding range of the window (the area to be blinded), the remote controller (not shown) is operated to close the winding motor 70. The operation is turned on, and the shaft 62 is rotated (normally rotated) by the winding motor 70 to wind the left and right wires 50 and 51 around the left and right reels 60 and 61. When the left and right wires 50 and 51 are wound, the left and right pulleys 35 and 36 rotate, and the height positions of the left and right shafts 33 and 34 of the uppermost slat 31A corresponding to the upper edge of the blind 30 are raised. Since the slat 31A moves upward, as a result, the entire blind 30 is lifted upward and gradually pulled out of the storage unit 40. At this time, the left and right pulleys 35 and 36 rotate, but the uppermost slat 31A and its left and right shafts 33 and 34 do not rotate but only move upward, and the inclination of the slat 31A does not change. When the uppermost slat 31A reaches a desired position, a remote controller (not shown) is operated to turn off the winding motor 70 to stop the ascent of the slat 31A.

  On the other hand, when the operation of opening the blind 30 is performed, that is, when the blind 30 is folded to reduce the light shielding range (the area to be blinded) of the window, a remote controller (not shown) is operated to open the winding motor 70. The operation is turned on, the shaft 62 is rotated in the opposite direction by the winding motor 70, and the left and right wires 50 and 51 are sent out from the left and right reels 60 and 61, respectively. When the left and right wires 50 and 51 are sent out, the left and right pulleys 35 and 36 rotate, and the height positions of the left and right shafts 33 and 34 of the uppermost slat 31A corresponding to the upper edge of the blind 30 are lowered. Since the slat 31A moves downward, as a result, the entire blind 30 is lowered downward, and gradually overlaps by its own weight in order from the lower slat 31, and is gradually stored in the storage unit 40. Also in this case, the left and right pulleys 35 and 36 rotate, but the uppermost slat 31A and its left and right shafts 33 and 34 do not rotate but only move downward, and the inclination of the slat 31A does not change. When the uppermost slat 31A reaches the lowermost or desired position, a remote controller (not shown) is operated to turn off the winding motor 70 and stop the descent of the slat 31A.

  Next, when adjusting the inclination of each slat 31 constituting the blind 30, a remote controller (not shown) is operated to turn on the inclination adjustment motor 90, and the inclination adjustment motor 90 turns the uppermost position on. One of the left and right shafts 33, 34 of the slat 31A (in this embodiment, the left shaft 33) is rotated to adjust the inclination of the slat 31A, and when the desired inclination is reached, the remote controller (Not shown) is operated to turn off the tilt adjusting motor 90 and stop the rotation of the shaft 33. Further, the other slats 31 disposed below the uppermost slat 31 </ b> A (however, the slats 31 protruding outside the storage unit 40) are also connected by the string-like member 32, so that these other slats The inclination of 31 is also adjusted at the same time. At this time, the left and right shafts 33 and 34 of the uppermost slat 31A rotate, but the left and right pulleys 35 and 36 do not rotate, and the height positions of the left and right shafts 33 and 34 do not change. Therefore, the raising / lowering control of the blind 30 by the winding motor 70 and the adjustment control of the inclination of each slat 31 by the inclination adjustment motor 90 are realized by independent drive mechanisms. If the tilt adjustment motor 90 is turned ON by operating a remote controller (not shown) and turned OFF at an appropriate timing, the tilt adjustment motor 90 is rotated in the opposite direction, and the inclination of each slat 31 is adjusted. It can be returned to the horizontal direction.

  According to this embodiment, there are the following effects. That is, in the light shielding device 10, when performing the operation of closing the blind 30, that is, when expanding the light shielding range by covering the window opening, the blind 30 is moved upward from the storage portion 40 provided in the lower portion 21 of the frame body 20. It can be pulled out gradually. Therefore, the winding motor 70 is stopped when the uppermost slat 31A corresponding to the upper edge of the blind 30 reaches an appropriate position where a blindfold desired for a person inside the window can be performed. Then, the blind 30 can be used to cover the lower part of the window opening and achieve appropriate blinding, and at the upper part of the window opening, a portion that is not shaded (blind) is formed to achieve appropriate lighting from the upper part. can do. For this reason, as a result of performing necessary blindfolding as in the case of a conventional light-shielding device, it is possible to eliminate the inconvenience that lighting cannot be performed at all and the room becomes dark.

  More specifically, a person inside the window can control the winding motor 70 composed of a stepper motor capable of fine ON / OFF control by operating a remote controller (not shown). Therefore, for example, the uppermost slat 31 </ b> A corresponding to the upper end edge of the blind 30 can be stopped at a free height according to his / her height. For this reason, it is possible to form a light-shielding range (hidden range) according to one's height at the lower part of the window opening, and to form a range to be opened for lighting at the upper part of the window opening. Can do. For this reason, it is possible to avoid the inconvenience that the room inside the window becomes totally dark, and it is a certain level of brightness without using a light during the daytime when sunlight enters from outside the window. Can be secured, so that the electricity bill can be saved. Moreover, since the blind 30 can be lifted and lowered electrically by operating a remote controller (not shown), for example, anyone such as a woman, a child, an elderly person, a short person, a person with no power, a handicapped person, etc. is easy. In addition, the opening / closing control of the blind 30 can be performed.

  In addition, from the viewpoint of blocking the line of sight from the outside of the window and protecting the privacy of those who are indoors, for example, in the windows of various private spaces where privacy should be strongly protected, such as bathrooms, toilets, and washrooms. It is effective if the apparatus 10 is installed. In particular, on the first floor of a house, there are many cases where a blind plate is installed on the window of the bathroom, etc., but the room becomes dark, so it is necessary to turn on the light even in the daytime. Since it is bad, the inconvenience that the room temperature becomes very high on a midsummer day occurs. On the other hand, if the light-shielding device 10 is installed, it is not necessary to turn on the light in the daytime. Therefore, the electricity bill can be saved, and if the inclination of each slat 31 is adjusted, the ventilation can be secured. Inconvenience due to the installation of the plate material can be eliminated.

  And if a fixed plate for blindfold is installed, it can be prevented from being looked out from outside the window, but at the same time, people outside the window look out of the window, for example, the weather is getting worse. It becomes impossible to grasp what has happened and the sun has fallen. On the other hand, if the light-shielding device 10 is installed, the upper part of the window opening can be opened, so that such inconvenience can be solved.

  Further, since the light shielding device 10 includes the inclination adjustment motor 90, the inclination adjustment of each slat 31 can be performed electrically by the inclination adjustment motor 90. For this reason, the user's labor accompanying adjustment operation can be reduced.

  Further, in the light shielding device 10, the case of the inclination adjusting motor 90 or a member fixed to the case is slid up and down by the guide rail 80, so that the posture of the inclination adjusting motor 90 is kept constant. The uppermost slat 31A can be rotated, and the inclination of the slat 31 can be adjusted stably. That is, the stator side of the inclination adjusting motor 90 moves up and down along the guide rail 80, but the posture is maintained so as not to rotate with respect to the space. It can be reliably transmitted to the uppermost slat 31A. More simply, when the uppermost slat 31A is rotated by the inclination adjustment motor 90, the inclination adjustment motor 90 can be prevented from wobbling with respect to the space together with the case.

  Note that the present invention is not limited to the above-described embodiment, and modifications and the like within a scope where the object of the present invention can be achieved are included in the present invention.

  For example, in the light shielding device 10 of the above embodiment, the light shielding body is the blind 30 formed by connecting a plurality of slats 31. However, the present invention is not limited to this, and the light shielding device 100 shown in FIG. As described above, the roll curtain 130 may be formed of a flexible sheet-like member. The material of the roll curtain 130 is arbitrary such as cloth or vinyl. Since the light shielding device 100 has the same configuration as the light shielding device 10 of the above-described embodiment except for the roll curtain 130, the same parts are denoted by the same reference numerals, and illustration and description thereof are omitted.

  In FIG. 5, the light shielding device 100 includes the frame body 20, similar to the light shielding device 10 of the above-described embodiment, and a storage unit 40 that stores the winding unit 131 of the roll curtain 130 is provided in the lower portion 21 of the frame body 20. The upper portion 22 of the frame body 20 is provided with a winding motor 70 that rotationally drives the shaft 62 of the reels 60 and 61 that winds the left and right wires 50 and 51, and the left side portion 23 and the right side of the frame body 20. The part 24 is provided with left and right guide rails 80 and 81 that slide up and down the left and right ends 134 and 135 of the shaft 133 provided on the upper edge 132 of the roll curtain 130. A part (part having the same configuration as the light shielding device 10 of the above embodiment) is not shown.

  The winding part 131 provided at the lower part of the roll curtain 130 is formed by being wound around a winding shaft 136, and the winding shaft 136 is wound in the direction in which the expanded roll curtain 130 is wound and stored. Left and right rewinding springs 137 and 138 for biasing are attached. Accordingly, the roll curtain 130 that is sent upward from the storage unit 40 and expanded is always pulled in the direction in which it is stored in the storage unit 40. Therefore, when the roll curtain 130 is expanded, it bends. Therefore, it is possible to maintain a light shielding posture, and it is possible to realize smooth storage without bending even when stored in the storage unit 40.

  The raising / lowering control of the roll curtain 130 by the winding motor 70 is the same as the raising / lowering control of the blind 30 of the embodiment. Unlike the blind 30, the roll curtain 130 does not correspond to the inclination adjustment of the slat 31, and therefore the roll curtain 130 is not provided with the one corresponding to the inclination adjustment motor 90 of the above embodiment. Therefore, in the light shielding device 100 of FIG. 5, the operation and effect relating to the inclination adjustment of the slat 31 of the embodiment cannot be obtained, but the other operations and effects are obtained in the same manner as the light shielding device 10 of the embodiment.

  Further, in the light shielding device 10 of the embodiment and the light shielding device 100 of FIG. 5 described above, the wires 50 and 51 are configured to suspend the upper edge of the light shielding body via the left and right pulleys 35 and 36. However, the present invention is not limited to this, and the ends of the wires 50 and 51 may be directly attached to the upper end edge of the light shielding body. For example, the load on the winding motor 70 may be reduced by increasing the number of installed pulleys.

  As described above, the light-shielding device of the present invention can be used when light-shielding or blinding a window provided in a fixed structure such as a building or a moving structure such as a ship, in particular, for example, a bathroom, a toilet, It is suitable for use in the case of shading or blinding a window provided in a specific purpose space such as a washroom.
