The rear protruding portion 61d is for pressing the pressed portion 93a of the rear sensor 93. The rear protruding portion 61d is formed so as to project forward and downward from the lower surface of the main body portion 61. The upper and lower intermediate portions of the rear protruding portion 61d are in light contact with the pressed portion 93a of the rear sensor 93 so that the rear sensor 93 does not react (to the extent that the pressed portion 93a is not pressed). .. In this way, the rear protruding portion 61d is arranged in contact with the pressed portion 93a of the rear sensor 93.

The beat 62 is for closing the space between the main body portion 61 and the outdoor ceiling 9 in a fully closed state (see FIG. 11) in which the building opening 6 is fully closed. The beat 62 is elastically deformable by a resin formed in a substantially plate shape. The beat 62 is formed so that its width in the left-right direction is substantially the same as the width in the left-right direction of the main body portion 61. The beat 62 is attached to the rear end portion of the main body portion 61, and the rear end portion abuts on the front end portion of the frame body 7a of the sash 7.

The uppermost slat 60 configured in this way is arranged with a slight gap upward with respect to the upper end portion of the front wall portion 21b of the box main body 21. Further, the uppermost slats 60 are arranged above the slats group 70 at intervals within a predetermined range.

The shutter device 10 can open and close the building opening 6 by the uppermost slat 60, the slat group 70, and the like configured as described above.

Hereinafter, the opening / closing operation of the shutter device 10 will be described with reference to FIGS. 5, 7 to 11. In the following, the operation of the shutter device 10 will be described by taking as an example the operation from the fully open state to the fully closed state shown in FIG.

The shutter device 10 drives the motor 111 to rotate the sprocket 112 shown in FIG. 7 and orbit the chain 113. As a result, the lower elevating member 114, the upper elevating member 115, the connecting member 116, and the uppermost arm member 101 are raised. At this time, the upper elevating member 115 ascends in the posture shown in FIG. 7 with the pin 115a sliding on the straight portion 31a. In this way, the uppermost slat 60 rises without rotating. The storage opening 21d is opened by raising the uppermost slat 60.

When the uppermost slat 60 rises, the link member 102 connecting the uppermost slat 60 and the slat 70 adjacent to the uppermost slat 60 (hereinafter referred to as "one lower slat 70") is vertically moved up and down. Rotate to face the direction. Then, when the link member 102 cannot rotate any more (rotates until the rotation is restricted by the restricting means), the arm member 101 connected to the slat 70 one level below rises.

As a result, as shown in FIG. 8, the lower slat 70 rises together with the uppermost slat 60 and moves from the storage opening 21d to the upper side of the front space S11. In this way, the slats 60 and 70 arranged above are sequentially ascended. When the slat 70 arranged at the lowermost position among the slat group 70 rises due to the rise, the interlocking member 80 rises as shown in FIG.

When the motor 111 is further driven from the state shown in FIG. 9, as shown in FIG. 10, the pin 115a of the upper elevating member 115 moves from the straight portion 31a to the curved portion 31b and guides forward and upward along the curved portion 31b. Will be done. Further, the rear lower portion of the upper elevating member 115 is pressed by the ascending lower elevating member 114 so as to rotate about the pin 115a. In this way, the upper elevating member 115 is rotated in the counterclockwise direction in FIG. 10 with the movement of the pin 115a. When the upper elevating member 115 starts to rotate, the front end portion of the arm member 101 is pushed downward and rotates in the counterclockwise direction in FIG. In this way, as shown in FIG. 11, the uppermost slat 60 and the slat group 70 rotate about 90 degrees in the counterclockwise direction, and the plate surface thereof faces the front-back direction. As a result, the postures of the uppermost slat 60 and the slat group 70 are changed from the state in which the plate surface faces in the vertical direction (lying) to the state in which the plate surface faces in the front-rear direction (stands up). As a result, the shutter device 10 fully closes the building opening 6 (switches to the fully closed state).

The interlocking member 80 is not rotated by the rotation of the arm member 101, and is arranged inside the storage opening 21d with the plate surface facing up and down in the fully closed state. As a result, the interlocking member 80 can close the storage opening 21d in the fully closed state. According to this, it is possible to prevent foreign matter B, rainwater, and the like from entering the inside of the storage box 20 through the storage opening 21d in the fully closed state. In the present embodiment, closing the storage opening 21d includes not only a state in which the storage opening 21d is closed with almost no gap, but also a state in which the storage opening 21d is closed with a certain gap. There is.

Further, the shutter device 10 can easily close the storage opening 21d by using the ascending operation of the opening / closing portion 50 by using the interlocking member 80 that cannot rotate to close the storage opening 21d. Further, since it is not necessary to rotate the interlocking member 80, it is possible to simplify the configuration for closing the storage opening 21d in the fully closed state.

When the building opening 6 is opened, the shutter device 10 drives the motor 111 to rotate the sprocket 112 in the direction opposite to the case where the building opening 6 is opened. As a result, the slats descend while rotating in the clockwise direction in FIG. 11 (the direction opposite to the case where the building opening 6 is opened) to open the building opening 6.

More specifically, as shown in FIG. 5, the slats group 70 and the interlocking member 80 descend and are housed in the front space S11 from the storage opening 21d. Further, in the slat group 70, the link member 102 is folded and stacked vertically without a gap.

On the other hand, as shown in FIGS. 5 and 6, the uppermost slat 60 is not housed in the front space S11 even if it descends, and the box body 21 has its plate surface oriented substantially in the vertical direction. Placed above. As a result, the uppermost slats 60 can close the storage opening 21d in the fully open state. According to this, it is possible to prevent foreign matter B and rainwater from entering the inside of the storage box 20 through the storage opening 21d in the fully open state.

Here, when the uppermost slat 60 is pressed from above (a load is applied downward) due to a person resting on it in the fully open state, the slat 60 swings or bends and is displaced downward to the box body. It comes into contact with the front wall portion 21b of 21. The front wall portion 21b is pressed from above through the uppermost slat 60 and tries to be deformed so as to fall forward (the storage opening 21d widens). According to the uppermost slat 60 according to the present embodiment, the locking portion 61b can be brought into contact with the front wall portion 21b. As a result, the locking portion 61b can support the front wall portion 21b, so that deformation of the front wall portion 21b can be restricted.

Further, the uppermost slat 60 is arranged with a gap with respect to the slat 70 one below in the fully open state. According to such a configuration, even when the foreign matter B is sandwiched between the slats 60 and 70 and the foreign matter B is fully opened, it is possible to suppress the uppermost slats 60 from being pushed up.

Specifically, when the foreign matter B invades the gap between the uppermost slat 60 and the one lower slat 70, the foreign matter B is sandwiched between the uppermost slat 60 and the one lower slat 70. It is possible to prevent the uppermost slat 60 from being pushed up.

Further, even if the foreign matter B is sandwiched between two adjacent slats in the slat group 70 and the slat group 70 floats up, there is a gap between the uppermost slat 60 and the next lower slat 70 in the fully open state. The top slat 60 is not pushed up.

Further, the uppermost slat 60 can discharge the foreign matter B and rainwater on the inclined surface 61a in the fully open state to the front, that is, to the outside by the inclined surface 61a of the main body portion 61.

Further, as shown in FIGS. 1 and 2, the house 1 includes a shutter device 10 that closes the building opening 6 (sash 7) by rising, so that the box body 21 (storage box 20) is sashed 7. By arranging it in the lower front part of the ceiling, it is possible to suppress the occurrence of a step on the ceiling surfaces of the indoor ceiling 5 and the outdoor ceiling 9. As a result, a ceiling surface that is flush with each other from the indoor side to the outdoor side can be formed, so that the comfort of the resident of the house 1 can be improved.

Further, the shutter device 10 can obscure the storage opening 21d by closing the storage opening 21d with the uppermost slat 60 in the fully open state, and can form a continuous floor surface between the indoor floor 4 and the outdoor floor 8. .. Therefore, the comfort of the resident of the house 1 can be improved.

Further, the storage opening 21d is arranged at substantially the same height as the floor surfaces of the indoor floor 4 and the outdoor floor 8. As a result, the box main body 21 can form a flush floor surface from the indoor side to the outdoor side so that a step does not occur between the indoor floor 4 and the outdoor floor 8. Therefore, the comfort of the resident of the house 1 can be improved.

Further, as shown in FIG. 11, in the uppermost slat 60, the beat 62 abuts on the outdoor ceiling 9 in the fully closed state. As a result, the beat 62 can close the main body portion 61 and the outdoor ceiling 9 without a gap, and can improve the blocking property of the building opening 6. As a result, it is possible to prevent birds, rainwater, and the like from invading between the top-level slats 60 and the outdoor ceiling 9. Further, it is possible to remove the discomfort that birds, rainwater, etc. may invade between the top-level slats 60 and the outdoor ceiling 9, and improve the comfort of the occupants of the house 1. Further, in order to eliminate the gap between the ceiling surface and the uppermost slat 60 in the fully closed state, it is not necessary to provide a frame or the like for receiving the uppermost slat 60. In this way, it is possible to create a series of sense of unity from the indoor side to the outdoor side of the ceiling surface, and it is possible to improve the comfort of the resident of the house 1.

Hereinafter, control of raising and lowering the opening / closing unit 50 using the detection unit 90 by the shutter device 10 will be described with reference to FIGS. 2, 12 and 13.

The shutter device 10 includes a predetermined control unit capable of acquiring the detection result of the detection unit 90, and the control unit controls the raising and lowering of the opening / closing unit 50 based on the detection result of the detection unit 90.

Specifically, the upper sensor 91 shown in FIG. 2 detects the foreign matter B when the foreign matter B blocks infrared rays in the rear upper part of the storage opening 21d. The shutter device 10 stops the raising and lowering of the opening / closing portion 50 based on the detection result of the upper sensor 91. Further, the shutter device 10 prohibits the opening / closing portion 50 from moving up and down while the upper sensor 91 detects the foreign matter B. As a result, in the shutter device 10, the foreign matter B located on the rear upper side (indoor side) of the storage opening 21d comes into contact with the opening / closing portion 50, and the foreign matter B is drawn into the storage opening 21d by the descending opening / closing portion 50. Can be suppressed.

Further, the upper sensor 91 is attached to the inner surface of the attachment 40. According to this, the space inside the attachment 40 can be effectively utilized.

Further, when the foreign matter B is inside the storage opening 21d, the front side sensor 92 and the rear side sensor 93 detect the foreign matter B. In the following, the case where the front sensor 92 detects the foreign matter B will be described with reference to FIGS. 12 and 13 as an example. In addition, in FIGS. 12 and 13, the arrows shown in white indicate the moving direction of the opening / closing portion 50. Further, in FIG. 13, the arrow painted in black indicates the direction of the load acting on the foreign matter B.

As shown in FIG. 12, when the opening / closing portion 50 descends with the foreign matter B sandwiched between two adjacent slats 70, the opening / closing portion 50 pushes the foreign matter B downward. In this way, the slats 70 will descend together with the foreign matter B.

As shown in FIG. 13, the foreign matter B is sandwiched between the front wall portion 21b of the box body 21 and the slats 70. At this time, the pressed portion 92a of the front sensor 92 comes into contact with the foreign matter B. When the foreign matter B is further pressed downward by the descending slats 70, a load on the front and lower sides acts on the foreign matter B to press the pressed portion 92a.

As a result, the front sensor 92 detects the foreign matter B. When the front sensor 92 detects the foreign matter B, the shutter device 10 stops the lowering / closing portion 50 from descending. The shutter device 10 may raise the opening / closing unit 50 for a predetermined time (short time) after stopping the lowering of the opening / closing unit 50.

According to this, the shutter device 10 can prevent the foreign matter B from being drawn into the storage opening 21d by the descending opening / closing portion 50 and the foreign matter B from entering the inside of the storage opening 21d. Further, it is possible to prevent the opening / closing portion 50 and the foreign matter B from being damaged due to a load.

When the foreign matter B is pressed downward by the slats 70 at the rear portion of the storage opening 21d, the foreign matter B presses the pressed portion 93a of the rear sensor 93, and the rear sensor 93 detects the foreign matter B. Also in this case, the shutter device 10 stops the lowering of the opening / closing portion 50 as in the case of the front sensor 92. Then, the shutter device 10 raises the opening / closing unit 50 for a predetermined time (short time). As a result, it is possible to prevent foreign matter B from entering from the rear portion of the storage opening 21d.

Further, the pressed portions 92a and 93a of the front side sensor 92 and the rear side sensor 93 according to the present embodiment are arranged in such a posture that they project diagonally upward. According to such a configuration, the protruding direction of the pressed portion 92a / 93a can be aligned with the direction of the load acting on the foreign matter B, so that the pressed portion 92a / 93a is easily pressed by the foreign matter B. Therefore, the foreign matter B can be accurately detected by the front sensor 92 and the rear sensor 93.

Further, as described above, the uppermost slat 60 is arranged with a slight gap from the front wall portion 21b of the box main body 21 in the fully open state shown in FIG. In this configuration, the uppermost slat 60 swings or bends and is displaced downward when pressed from above by a person or the like. The front protruding portion 61c and the rear protruding portion 61d move downward due to the displacement, and press the pressed portions 92a and 93a of the front sensor 92 and the rear sensor 93.

As a result, the front sensor 92 and the rear sensor 93 detect the downward displacement of the uppermost slat 60 in the fully open state. The shutter device 10 prohibits the opening / closing unit 50 from moving up and down by the detection. This makes it possible to prevent the opening / closing portion 50 from rising when the uppermost slat 60 is pressed from above. As a result, it is possible to prevent the opening / closing portion 50 from rising against the pressing force from above and prevent the opening / closing portion 50 and the motor 111 from being loaded.

Further, when the uppermost slat 60 is not displaced downward (not pressed from above), the uppermost slat 60 has a front protruding portion 61c and a rear protruding portion 61d, and a front sensor 92 and a rear sensor. The pressed portions 92a and 93a of 93 are in contact with each other. According to such a configuration, when the uppermost slat 60 is displaced downward, the pressed portions 92a and 93a can be reliably pressed by the front protruding portion 61c and the rear protruding portion 61d. Therefore, the downward displacement of the uppermost slat 60 can be accurately detected.

Further, in the shutter device 10, when the opening / closing portion 50 is lowered (when the building opening 6 is opened), when a load higher than the load assumed for lowering the opening / closing portion 50 is applied to the motor 111, the shutter device 10 is lowered. It stops and raises the opening / closing unit 50 for a predetermined time (only for a short time). According to this, even if the detection unit 90 cannot detect the foreign matter B and the foreign matter B is caught between the opening / closing part 50 and the front wall part 21b, an excessive load is applied to the motor 111 and the opening / closing part 50. It can be suppressed.

Hereinafter, the drainage structure of the storage box 20 will be described with reference to FIGS. 14 to 16. 14 (a), 15 and 16 are views of the storage box 20 in which the case 22 is provided, cut out for the purpose of explaining the drainage structure.

As shown in FIG. 14, the shutter device 10 includes a first discharge unit 121 and a second discharge unit 122 as a drainage structure.

The first discharge unit 121 is for discharging the rainwater W (see FIG. 15) that has entered the upper space S10. Further, the first discharge portion 121 is a gap formed between the storage box 20 and the foundation 2. Specifically, the first discharge portion 121 is a gap formed between the rear end portion of the bottom portion 21a of the box body 21, the rear end portion of the case 22, the rear end portion of the partition 23, and the foundation 2. be. The first discharge portion 121 is formed by arranging the storage box 20 (box main body 21) in front of the foundation 2 at a slight distance.

The second discharge unit 122 is for discharging the rainwater W that has entered the lower space S20. The second discharge portion 122 is formed so as to penetrate the lower surface of the case 22. The second discharge portion 122 is formed in a front portion (a portion having a low height) on the lower surface of the case 22. A plurality of second discharge portions 122 are formed at intervals in the front-rear direction and the left-right direction.

Since the storage opening 21d of the shutter device 10 faces upward, when the opening / closing part 50 is moved up and down on a rainy day, as shown in FIG. 15, the inside of the storage box 20 (upper space S10) is entered from the storage opening 21d. ) May be invaded by rainwater W. The rainwater W moves downward along the front wall portion 21b, the vertical frame 30, and the like, and reaches the partition 23. The rainwater W is guided backward and downward along the inclined surface 23a of the partition 23, and reaches the rear end portion of the partition 23.

The rainwater W that has reached the rear end of the partition 23 is flushed to the first discharge section 121 and falls down the first discharge section 121. As a result, the first discharge unit 121 can discharge the rainwater W that has entered from the storage opening 21d from the upper space S10 to the outside of the storage box 20.

According to this, since the first discharge unit 121 can suppress the accumulation of the rainwater W in the upper space S10, the corrosion due to the rainwater W can be suppressed. Further, since the partition 23 can suppress the rainwater W from entering the lower space S20 from the upper space S10, it is possible to suppress the rainwater W from coming into contact with the motor 111.

Further, the rainwater W can be guided from the front space S11 to the first discharge portion 121 by using the inclined surface 23a. As a result, the rainwater W can be easily discharged from the first discharge unit 121.

Here, the partition 23 is arranged at a position higher than the lower end portion of the slit 31 (straight portion 31a) of the vertical frame 30. Further, the partition 23 is arranged with a slight gap in the left-right direction with respect to the vertical frame 30, the attachment 40, and the side wall portion 21c (see FIG. 4).

According to such a configuration, even if a large amount of rainwater W invades the storage box 20 due to heavy rain or the like and the rainwater W cannot be completely discharged by the first discharge portion 121, the rainwater W can be discharged to the straight portion of the slit 31. It can escape downward from the gap between the 31a, the vertical frame 30 and the like and the partition 23. As a result, the storage box 20 can effectively suppress the accumulation of rainwater W in the upper space S10.

Further, as shown in FIG. 16, the rainwater W that has escaped downward from the straight portion 31a or the like of the slit 31 will flow out to the lower space S20. The rainwater W moves downward in the lower space S20 and reaches the lower surface of the case 22. The rainwater W is guided forward and downward along the lower surface of the case 22, is flown to the second discharge unit 122, and falls down the second discharge unit 122. As a result, the second discharge unit 122 can discharge the rainwater W that has escaped to the lower space S20 to the outside of the storage box 20.

According to this, even if the rainwater W is released to the lower space S20, the second discharge unit 122 can suppress the rainwater W from accumulating in the rear space S12. Therefore, it is possible to suppress the corrosion caused by the rainwater W and also to prevent the rainwater W from coming into contact with the motor 111.

Hereinafter, the maintenance procedure of the storage box 20 will be described with reference to FIGS. 17 and 18.

In the following, as shown in FIG. 17, the maintenance procedure will be described by taking as an example the case where the foreign matter B that has entered the inside of the storage box 20 is removed.

The foreign matter B shown in FIG. 17 has fallen into the storage box 20 from the storage opening 21d and is located in the rear space S12. When removing the foreign matter B, as shown in FIG. 18, the uppermost slat 60 and the rear closing member 24 are removed.

As a result, the upper part of the upper space S10 is opened, and the foreign matter B can be grasped by reaching out from the upper part of the rear space S12. In this way, the foreign matter B is removed from above the storage opening 21d. According to this, even if there is an outdoor floor 8 around the box body 21 (front, left and right) (see FIGS. 1 and 2), the storage box 20 can be stored without the outdoor floor 8 getting in the way. Can be maintained. Further, the foreign matter B can be removed by removing one of the slats 60 and 70. As described above, the storage box 20 can be easily maintained.

Further, depending on the size of the foreign matter B and the like, it is assumed that the foreign matter B cannot be removed only by removing the uppermost slat 60 and the rear closing member 24. Even in such a case, if some slats of the slats group 70 are removed, a space for removing the foreign matter B can be easily secured. Therefore, the storage box 20 can be easily maintained.

Further, in the present embodiment, in addition to the uppermost slat 60 and the slat group 70, the interlocking member 80 and the partition 23 are also removably configured. Therefore, if all the slats 60/70, the interlocking member 80, and the partition 23 are removed, the motor 111 can be maintained from above. Therefore, the motor 111 can be easily maintained.

Further, the box main body 21 according to the present embodiment can remove the foreign matter B through the rear space S12 in which the member is not particularly housed. As described above, since the rear space S12 can be used as the maintenance space in the box body 21, the foreign matter B can be easily removed only by removing the uppermost slat 60 and the rear closing member 24. .. Further, the slat group 70 and the interlocking member 80 can be easily removed via the rear space S12. In this way, when the slat group 70 and the interlocking member 80 are removed, there is a relatively large space inside the box body 21. In this way, the operator can easily access the large space inside the box body 21, for example, from above the box body 21. As a result, the operator can easily maintain the storage box 20. Further, by forming the rear space S12 inside the attachment 40, the space inside the attachment 40 can be effectively utilized.

Further, in the present embodiment, by removing the rear closing member 24, the rear sensor 93 attached to the rear closing member 24 can also be removed together. As a result, the rear sensor 93 can be easily maintained.

Further, the partition 23 includes an inclined surface 23a that inclines toward the rear (rear space S12). According to the inclined surface 23a, the foreign matter B that has fallen on the partition 23 can be guided to the rear space S12. As a result, the foreign matter B can be easily arranged in the rear space S12 and easily removed from the box body 21.

As described above, the shutter device 10 according to the present embodiment is provided so as to be able to move up and down, and a fully closed state in which the building opening 6 is fully closed by ascending and a fully opened state in which the building opening 6 is fully opened by descending. A storage box 20 having an opening / closing portion 50 for switching between states and a storage opening 21d (opening) opened upward, and the opening / closing portion 50 can be stored inside via the storage opening 21d. The uppermost slat 60 (the uppermost portion of the opening / closing portion 50) is formed larger than the storage opening 21d so as to close the storage opening 21d of the storage box 20 upward in the fully opened state. It is what has been done.

With such a configuration, it is possible to prevent rainwater W, foreign matter B, and the like from entering the inside of the storage box 20 in the fully open state. Further, since the uppermost slats 60 are used for both opening and closing the building opening 6 and opening and closing the storage opening 21d, the number of parts can be reduced and the labor for assembling can be saved.

Further, the uppermost slat 60 is provided with a locking portion 61b (regulatory means) for restricting the deformation of the storage opening 21d so as to expand in the fully open state.

With this configuration, even when the uppermost slat 60 presses the storage box 20 from above in the fully open state, it is possible to prevent the storage box 20 from being deformed so that the storage opening 21d is widened. Can be done.

Further, the locking portion 61b regulates the deformation of the storage opening 21d by being locked to the upper end portion of the storage box 20 (front wall portion 21b of the box body 21) in the fully open state. Is.

With such a configuration, it is possible to suppress the deformation of the storage opening 21d of the storage box 20 so as to be widened by a simple configuration in which the locking portion 61b is only caught on the upper end of the storage box 20.

Further, the uppermost slat 60 is arranged with a gap between the uppermost slat 60 and at least a part of the upper end portion of the storage box 20 in the fully open state, and the shutter device 10 is the uppermost slat 60. When the front sensor 92 and the rear sensor 93 (detection means) for detecting the displacement are provided and the displacement of the uppermost slat 60 in the fully opened state is detected by the front sensor 92 and the rear sensor 93, the displacement is detected. It regulates the rise of the opening / closing portion 50.

With this configuration, it is possible to restrict the opening / closing portion 50 from rising when the uppermost slat 60 is pressed from above in the fully open state. Specifically, the uppermost slat 60 is arranged with a gap between it and the upper end of the storage box 20, so that it is pressed from above when a person is placed and is lowered with respect to the storage box 20. You will be able to displace to. By detecting the displacement of the uppermost slat 60 with the front side sensor 92 and the rear side sensor 93, it is possible to grasp that the uppermost slat 60 is pressed from above. In this case, if the ascending / descending portion of the opening / closing portion 50 is restricted, it is possible to restrict the opening / closing portion 50 from rising when the uppermost slat 60 is pressed from above in the fully open state.

Further, the uppermost slat 60 is provided with a front protruding portion 61c and a rear protruding portion 61d (protruding portion) formed so as to project downward, and the front protruding portion 61c and the rear protruding portion 61d are provided with the front protruding portion 61c and the rear protruding portion 61d. , Which is formed in contact with the front side sensor 92 and the rear side sensor 93 in the fully open state.

With this configuration, the front protruding portion 61c and the rear protruding portion 61d can be brought close to each other in advance with the front sensor 92 and the rear sensor 93 in a state where the uppermost slat 60 is not pressed from above. can. According to this, the front sensor 92 and the rear sensor 93 can be reliably pressed by the front protrusion 61c and the rear protrusion 61d with the displacement of the uppermost slat 60. Therefore, it is possible to accurately detect that the uppermost slat 60 is pressed from above in the fully open state.

Further, the opening / closing portion 50 is an aggregate of a plurality of slats arranged side by side in the vertical direction, and among the plurality of slats, the slats adjacent to each other have a predetermined range of lower slats with respect to the upper slats. Suspended in close proximity to each other, the uppermost slat 60 among the plurality of slats is spaced within the predetermined range from the uppermost slat 70 in the fully open state. It is the one that is arranged.

With this configuration, even if the foreign matter B enters the storage box 20, it is possible to prevent the uppermost slat 60 from being pushed up by the influence of the foreign matter B in the fully opened state. As a result, even if the foreign matter B intrudes into the storage box 20 in the fully open state, the uppermost slat 60 can be arranged in the initial normal position.

The storage opening 21d according to the present embodiment is an embodiment of the opening according to the present invention.
