Description

  The present invention relates to a shutter that protects an opening such as a window of a building, and more particularly to a shutter that can be opened and closed vertically.

  Openings such as windows (hereinafter simply referred to as windows) provided in buildings may be damaged or cracked by flying objects during strong winds such as typhoons. Therefore, in order to protect the window in the case of heavy wind and rain, it is common to provide a shutter outside the window. An example of a conventional general shutter will be described below with reference to FIGS.

  A conventional shutter 101 includes a plurality of rectangular flat-plate-shaped shutters 102, a door pocket 103 in which the shutters 102 can be stacked and stored, and a pair of sashes 104 that support the shutters 102 up and down. The shutter panel 102 is formed slightly larger than the window W of the building, and can be protected by covering the window W. The door pocket 103 is a flat box shape that is slightly thicker than a stack of several rain door plates 102 so that the rain door plates 102 can be accommodated, and one of the left and right sides is open. A shutter panel 102 can be inserted. The pair of sashes 104 are formed in a long and narrow bar shape having a U-shaped cross section provided with a groove 106 on which the shutter panel 102 can slide.

  When the conventional shutter 101 constructed as described above is attached to a building, a pair of sashes 104 are arranged in parallel on the upper and lower sides of the window W so that the grooves 106 face each other. The shutter board 102 is inserted into the groove 106 of 104, and the shutter board 102 is slidably attached to the left and right. The door pocket 103 is attached to the left or right side of the window W on the outer wall G of the building so that the opening 105 faces the window W side.

  When there is no need to protect the window W, such as in fine weather, the shutter door 102 is housed in the door pocket 103 and the shoji door and the glass door are exposed to the outside as shown in FIG. Then, when it is necessary to protect the window W due to heavy wind and rain, the shutter panel 102 is slid along the pair of sashes 104 and pulled out from the door pocket 103 as shown in FIG. Then, as shown in FIG. 18, the window W is completely covered with the shutter panel 102 to protect the shoji door and the glass door. In this way, the conventional shutter 101 repels with the shutter panel 102 without hitting the window W even when a flying object flies from the outside, so that the window W can be protected when the wind and rain are heavy.

  However, since the conventional shutter 101 as described above needs to be provided with the door pocket 103 on the outer wall G, it cannot be attached when there is not enough space on the outer wall G. In particular, in recent years, there is a tendency to increase the window W, and there are many buildings where the conventional shutters 101 cannot be provided. Moreover, since the door pocket 103 covers the part of the outer wall G, the structure which provides the door pocket 103 as mentioned above will impair the aesthetics of a building.

  On the other hand, in order to solve the problems of the conventional shutter 101 as described above, a pair of guide rails are extended in the vertical direction, and a slat plate connected vertically between the pair of guide rails slides up and down. A sliding shutter having a configuration is used (for example, Patent Document 1). However, using a sliding shutter often detracts from the beauty of the building. In addition, the sliding shutter is often more expensive than a shutter.

Therefore, in order to solve the above-mentioned problems, a structure in which a transparent or translucent resin plate is configured to be detachable from the upper and lower pair of screen door rails has been proposed (for example, Patent Document 2). In this case, the installation cost is not high and there is no need to provide a door pocket.
JP 2005-42357 A JP 2006-233634 A

  However, the screen door rail is usually approximately the same length as the width of the window, so if the resin plate is fixed to the outside of the screen door rail, the resin plate always covers the window. There is a risk that the aesthetics of the building may be damaged, and it is also noticeable when looking outside from the inside of the building.

  The present invention has been made in view of the above circumstances and problems, and can be applied even if the space of the building outer wall is insufficient for installing a conventional shutter, and is excellent in aesthetics. The purpose is to provide open shutters.

  In order to achieve the above object, a folding shutter according to the invention of claim 1 includes a pair of left and right slide rails provided on the left and right sides of a window on the outer wall of a building so that the length direction is vertical, and the window.

  The folding shutter according to claim 8 is the folding shutter according to any one of claims 1 to 7, wherein the folding door is folded at the upper end side of the window by the opening and closing means. An eaves part provided so as to protrude from the upper side of the window on the outer wall to the outside of the building is provided.

  In the folding shutter of claim 1, the pair of left and right slide rails are provided on the right and left sides of the window on the outer wall of the building so that the length direction is the vertical direction. The folding door includes a plurality of rectangular plate bodies that cover the window, and a connecting portion that is rotatably connected so that the plate bodies can be alternately bent inward and outward, and further has an upper end thereof. Is fixed at the upper position of the window, and can be folded around the connecting portion as an axis above the window. Furthermore, a slide member that is slidably attached along the length direction of the pair of slide rails and that rotatably supports a connecting portion located inside when the folding door is folded, and a slide member By sliding up and down, the folding door is folded at the upper end side of the window to open the window, or is provided with an opening and closing means for closing the window in a plane. By sliding to, a state where the window is opened and a state where the window is closed can be taken.

  When the folding door is in a state of opening the window, that is, in a state of overlapping the upper part of the window and projecting substantially perpendicularly to the outer wall of the building (hereinafter referred to as an open state), the shape is similar to the so-called eaves of the building. Therefore, it can play the same role as the so-called eaves. In other words, it is possible to prevent the sunlight of the sun at a high position in summer from entering the room, and it is possible to prevent rain from entering the room even when the window is opened in the case of rain without strong winds. And since it is the same shape as the eaves conventionally provided in a Japanese building, the aesthetics of a building are not spoiled. In addition, by using the eaves shape as described above, it is not necessary to provide a door pocket like a conventional shutter, and even if the space of the building outer wall is insufficient to install a conventional shutter, it can be attached. it can. Here, the “eave” means a single-flow small roof that protrudes from the top of the building window.

  Also, when the window is closed (hereinafter referred to as the closed state), the folding doors are connected in parallel and in a straight line so as to cover the window, so that the entire window of the building can be covered from the outside. Even if a flying object flies from the outside due to strong winds or the like, it does not hit the building window and bounces off at the folding door, so that it is possible to protect the building window in case of heavy wind and rain.

  As described above, the folding shutter of claim 1 can be applied even if the space on the outer wall of the building is insufficient to install a conventional shutter, and has excellent aesthetics. it can.

Can be pulled up to open. Also, when the folding door is in the open state, the lower edge of the folding door moves downward along the slide rail by its own weight by operating the winding device and pulling out the flexible string material. It will be fixed. Therefore, the folding shutter can be freely changed between the open state and the closed state. In particular, if the hoisting device is an electric one, it can be opened and closed without requiring human power.

  According to a third aspect of the present invention, the folding shutter includes a flexible string member, an urging unit, and a locking unit as an opening / closing unit. One end of the flexible string member is fixed to the slide member located at the lowest position. The biasing means biases the other end of the flexible string material upward. When the flexible string material is biased upward, the slide member fixed to the flexible string material slides upward. Since the folding door constituting the folding shutter is configured to be opened and closed through the sliding member, if the sliding member is slid upward by biasing the flexible string material upward, the folding door is moved to the window. It can be set as the open state arrange | positioned upwards. On the other hand, it can be locked in the closed state by pulling down the lower end of the folding door in the open state and locking it with the locking means as a closed state that is in a straight line parallel to the window. Therefore, when opening the folding shutter in clear weather, etc., the folding door is not locked by the locking means, so that the folding door is fixed to the open state in which it protrudes from the outer wall of the building above the window. be able to. On the other hand, when closing the folding shutter, such as when the weather is heavy, pull down the lower end of the folding door, close the folding door and lock the folding door with the locking means, and fix it in the closed state can do.

  Therefore, according to the folding shutter of the third aspect, when the folding door is shifted from the closed state to the open state, the plate body can be pulled up without removing any other force by simply removing the locking means. In general, when pulling upward from below, more force is required than when pulling downward from above, so that it is possible to easily open the cover. In addition, by adjusting the force of the urging means, it can be made to be able to be pulled down with a smaller force when being pulled down from above.

  According to the folding shutter of the fourth aspect, the plurality of locked members are arranged in the middle in the length direction of the slide rail, and the locking members that are detachably attached to the locked members are fixed to the slide member. Therefore, the sliding member can be fixed by engaging the locking member with the locked member, and the sliding member can be made slidable by removing the locking member from the locked member. And since the to-be-latched members are provided in a plurality of rows in the middle of the slide rail, the folding door can be opened and closed by fixing the latching member of the slide member to an arbitrary to-be-latched member. Can be maintained in between. By maintaining such a state, it is possible to ventilate the room while preventing rain from entering the room when there is no wind or light wind.

  According to the foldable shutter of claim 5, since the folding door is made of a highly light-transmitting synthetic resin, even when the foldable shutter is kept closed in the case of wind and rain, Can be taken indoors. Further, since it is made of synthetic resin, it can be made extremely light and inexpensive.

  According to the folding shutter of the invention of claim 6, the folding door is made of polycarbonate, and the polycarbonate is excellent in impact resistance. Therefore, when a flying object flies from the outside, it is less likely to be damaged. You can keep your windows safe. Polycarbonate also has excellent dimensional stability, is not easily deformed by heat, and can withstand long-term use.

  According to the folding shutter of the invention of claim 7, since the folding door is made of plastic with high light transmittance and reflects ultraviolet rays, visible light and infrared rays enter the room to brighten the room, and Can be kept high, and ultraviolet rays are not incident on the room, so that it does not harm people in the room and can prevent discoloration of tatami mats, carpets, furniture, and the like.

Further, the upper ends of the frames 32d and 32h attached to the left and right side edges of the lowermost plate 31d are rotatably connected to the lower ends of the frames 32c and 32g directly above. The lower ends of the frames 32d and 32h are rotatably attached to the lower slide member 5. Accordingly, the plate bodies 31a to 31d are connected to the building windows W in a row and cover the building windows W, as shown in FIG. 6, and from the plate bodies 31a as shown in FIG. It is possible to freely shift to a state where 31d overlaps and protrudes from the building outer wall above the building window W.

Here, as shown in FIG. 6, a state in which the lower end of the folding door 3 is pulled downward and the folding door 3 is stretched in a straight line to cover the outside of the window W is referred to as a closed state. That is, a state in which the lower ends of the plate 31d positioned at the lowermost part of the folding door 3 and the frames 32d and 32h fixed to the left and right side edges of the plate 31d are pulled down to the lowest is referred to as a closed state. In addition, as shown in FIG.
A state in which the lower end of the folding door is pulled up and the plates 31a to 31d constituting the folding door are overlapped and arranged on the upper side of the window W is referred to as an open state. In this way, the folding shutter 1 can cover the outside of the window W when closed, and can protect the window W against wind and rain and flying objects from the outside. Since it has a shape protruding from the outer wall G, it can play a role of eaves and can prevent the strong sunlight from entering, and can also prevent the rain from entering the room when the rain is weak.

  One end of the flexible string 6 is fastened to the lower slide member 5 among the slide members 5 that can slide on the right slide rail 2a. The flexible string material 6 is formed of, for example, a wire rope, and can be rolled up and drawn down by a winding device 7. As shown in FIG. 8, the hoisting device 7 includes a pulley 71, a shaft member 72, and a motor device 73. The pulley 71 is fixed to the outer wall G immediately above the right slide rail 2a, and the other end of the flexible string 6 is fixed. The shaft member 72 is a rod-shaped member having a circular cross section that extends in the direction of the rotation axis of the pulley 71. The motor device 73 is a motor that can receive a power supply from a power source (not shown) and can rotate the shaft member 72 forward and backward, and can be operated by a remote controller from within a building, for example. The motor device 73 can be rotated forward and backward when electric power is supplied, but is not rotated when the power is turned off.

  When the motor device 73 is rotated counterclockwise when viewed from the left direction, rotational torque is transmitted to the shaft member 72, and the pulley 71 is rotated counterclockwise when viewed from the left direction. When the pulley 71 rotates, the flexible string material 6 is wound up, and the lower slide member 5 to which one end of the flexible string material 6 is bound slides upward. As a result, the frames 32d and 32h and the lowermost plate 31d that are rotatably supported by the slide member 5 are moved upward, and the folding shutter 1 as shown in FIGS. Is open. On the other hand, when the motor device 73 is rotated clockwise as viewed from the left in the open state, this rotational torque is transmitted to the shaft member 72, and the pulley 71 rotates clockwise as viewed from the left. . Therefore, the flexible string material 6 wound around the pulley 71 is drawn downward, and the slide member 7 to which the end of the flexible string material 6 is bound is rotated by its own weight and the slide member 5. The frame slides downward by the weights of the frames 32a to 32h and the plate bodies 31a to 31d, which are fixedly movable. And as shown to (a) of FIG. 4 and FIG. 6, the folding shutter 1 will be in an open state.

  In the present embodiment, the hoisting device 7 includes the electric motor device 73. However, the hoisting device 7 may include a manual rotating device. The manual rotation device only needs to have a configuration capable of transmitting rotational torque to the pulley 71. For example, a handle that rotates by an operator's operation, a torque transmission belt that transmits rotational torque of the handle to the pulley 71, and As long as it has. When the manual rotation device is used, the operation handle is preferably in a position where the operator can easily operate.
