Thus, the front projecting portion 61c is arranged in contact with the pressed portion 92a of the front sensor 92 .

The rear protrusion 61 d is for pressing the pressed portion 93 a of the rear sensor 93 . The rear projecting portion 61d is formed to project forward and downward from the lower surface of the main body portion 61 . The rear protruding portion 61d is in light contact with the pressed portion 93a of the rear sensor 93 at its upper and lower middle portions so that the rear sensor 93 does not react (to the extent that it does not press the pressed portion 93a). . Thus, the rear protrusion 61d is arranged in contact with the pressed portion 93a of the rear sensor 93. As shown in FIG.

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

The uppermost slat 60 configured in this manner is arranged with a slight gap upward from the upper end portion of the front wall portion 21b of the box body 21 . Moreover, the highest slat 60 is arranged above the slat group 70 with an interval within a predetermined range.

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

The opening/closing operation of the shutter device 10 will be described below with reference to FIGS. 5 and 7 to 11. FIG. Note that the operation of the shutter device 10 will be described below by taking the operation from the fully open state to the fully closed state shown in FIG. 5 as an example.

The shutter device 10 drives the motor 111 to rotate the sprocket 112 shown in FIG. 7 and rotate 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 lifted. At this time, the pin 115a slides on the straight portion 31a, and the upper elevating member 115 is lifted while maintaining the posture shown in FIG. Thus, the top slat 60 rises without pivoting. The storage opening 21d is opened by raising the uppermost slat 60. As shown in FIG.

When the top slat 60 rises, the link member 102 connecting the top slat 60 and the slat 70 adjacent below it (hereinafter referred to as "the slat 70 one level below") moves up and down in its longitudinal direction. Rotate to face the direction. Then, when the link member 102 can no longer rotate (it rotates until it reaches the direction in which rotation is restricted by the restriction 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 upward from the storage opening 21d to the front space S11. In this way, the slats 60 and 70 arranged above are sequentially lifted. When the lowermost slat 70 of 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 is guided forward and upward along the curved portion 31b. be done. Further, the lower rear part of the upper elevating member 115 is pressed by the rising lower elevating member 114 so as to rotate about the pin 115a. Thus, the upper elevating member 115 is rotated counterclockwise in FIG. 10 as the pin 115a moves. When the upper elevating member 115 starts to rotate, the front end of the arm member 101 is pushed downward and rotates counterclockwise in FIG. Thus, as shown in FIG. 11, the uppermost slat 60 and the group of slats 70 are rotated counterclockwise by about 90 degrees so that their plate surfaces face the front-rear direction. As a result, the top slat 60 and the group of slats 70 are changed in posture from a state in which the plate surfaces face the vertical direction (lie down) to a state in which the plate faces face the front-back direction (stand up). Thereby, the shutter device 10 fully closes the building opening 6 (switches to a fully closed state).

The interlocking member 80 is not rotated by the arm member 101, and is arranged inside the storage opening 21d with its plate surface facing up and down in the fully closed state. Thereby, the interlocking member 80 can block 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 this embodiment, closing the storage opening 21d includes not only closing the storage opening 21d with almost no gap, but also closing the storage opening 21d with a certain amount of gap. there is

Further, the shutter device 10 uses the non-rotatable interlocking member 80 for closing the storage opening 21d, so that the opening 21d can be easily closed using the upward movement of the opening/closing unit 50. FIG. Moreover, since it is not necessary to rotate the interlocking member 80, the configuration for closing the storage opening 21d in the fully closed state can be simplified.

When the building opening 6 is opened, the shutter device 10 drives the motor 111 to rotate the sprocket 112 in the opposite direction to when the building opening 6 is opened. As a result, the slat moves downward while rotating clockwise in FIG.

More specifically, as shown in FIG. 5, the slat group 70 and the interlocking member 80 are lowered and stored in the front space S11 through the storage opening 21d. In addition, the slat group 70 is vertically stacked with no space between them by folding the link member 102 .

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 is lowered, and is placed on the box body 21 with its plate surface directed substantially vertically. placed above. Thereby, the uppermost slat 60 can block the storage opening 21d in the fully opened state. According to this, it is possible to prevent foreign matter B and rainwater from entering the interior of the storage box 20 through the storage opening 21d in the fully opened state.

Here, when the highest slat 60 is pressed from above (a downward load is applied) such as when a person sits on the slat 60 in the fully opened state, the slat 60 swings or bends and is displaced downward to displace the box body. 21 abuts on the front wall portion 21b. The front wall portion 21b is pressed from above via the uppermost slat 60, and tries to deform so as to fall forward (the storage opening 21d widens). According to the uppermost slat 60 according to this embodiment, the engaging 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.

In addition, the uppermost slat 60 is arranged with a gap from the slat 70 one below it in the fully open state. According to such a configuration, even if a foreign object B is caught between the slats 60 and 70 and the slats 60 and 70 are fully opened, it is possible to prevent the uppermost slat 60 from being pushed up.

Specifically, when a foreign object B enters the gap between the top slat 60 and the slat 70 one level below, the foreign object B is caught between the top slat 60 and the slat 70 one level below. It is possible to suppress the uppermost slat 60 from being pushed up.

Further, even if a foreign object B is caught 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 slat 70 one lower in the fully opened state. The top slat 60 is never pushed up.

In addition, the uppermost slat 60 can discharge the foreign matter B and rainwater placed on the inclined surface 61a in the fully opened 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, thereby closing the box body 21 (storage box 20) to the sash 7. By arranging it in the front lower part of the , 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 from the indoor side to the outdoor side can be formed, so that the comfort of the residents of the house 1 can be improved.

Further, the shutter device 10 closes the storage opening 21d with the uppermost slat 60 in the fully open state, thereby making the storage opening 21d difficult to see and forming a continuous floor surface with the indoor floor 4 and the outdoor floor 8. - 特許庁. Therefore, the comfort of the residents 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 shown in FIG. As a result, the box main body 21 prevents the generation of a step between the indoor floor 4 and the outdoor floor 8, thereby forming a flush floor surface from the indoor side to the outdoor side. Therefore, the comfort of the residents of the house 1 can be improved.

Also, as shown in FIG. 11, the topmost slat 60 contacts the outdoor ceiling 9 with the beat 62 in the fully closed state. As a result, the beat 62 closes the main body 61 and the outdoor ceiling 9 without any gap, thereby improving the blocking performance of the building opening 6 . As a result, it is possible to prevent birds, rainwater, and the like from entering between the uppermost slat 60 and the outdoor ceiling 9. - 特許庁In addition, the comfort of the residents of the house 1 can be improved by eliminating the discomfort that birds, rainwater, etc. may enter from between the top slat 60 and the outdoor ceiling 9. - 特許庁Further, in order to eliminate the gap between the ceiling surface and the highest slat 60 in the fully closed state, it is not necessary to provide a frame or the like for receiving the highest slat 60 . In this way, it is possible to create a sense of unity from the indoor side to the outdoor side on the ceiling surface, and improve the comfort of the residents of the house 1. - 特許庁

Below, control of elevation of 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. FIG.

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

Specifically, the upper sensor 91 shown in FIG. 2 detects the foreign matter B when the foreign matter B blocks the infrared rays behind and above the storage opening 21d. The shutter device 10 stops lifting 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 is detecting the foreign object B. As shown in FIG. As a result, the opening/closing portion 50 does not come into contact with the foreign matter B present behind the storage opening 21d (on the indoor side), or the foreign matter B is drawn into the storage opening 21d by the opening/closing portion 50 that descends. can be suppressed.

Also, 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, the front sensor 92 and the rear sensor 93 detect the foreign matter B when the foreign matter B is inside the storage opening 21d. An example in which the front sensor 92 detects a foreign object B will be described below with reference to FIGS. 12 and 13 . In FIGS. 12 and 13 , the white arrow indicates the moving direction of the opening/closing portion 50 . Further, in FIG. 13, the black arrow indicates the direction of the load acting on the foreign object B. As shown in FIG.

As shown in FIG. 12, when the opening/closing part 50 descends with the foreign object B sandwiched between the two adjacent slats 70, the foreign object B is pushed downward. Thus, the slat 70 descends together with the foreign object B.

The foreign matter B is caught between the front wall portion 21b of the box body 21 and the slat 70, as shown in FIG. At this time, the pressed portion 92a of the front sensor 92 comes into contact with the foreign object B. As shown in FIG. When the foreign object B is further pressed downward by the descending slat 70, a forward downward load acts and presses the pressed portion 92a.

Thereby, the front sensor 92 detects the foreign object B. As shown in FIG. When the front sensor 92 detects the foreign object B, the shutter device 10 stops lowering the opening/closing portion 50 . In addition, the shutter device 10 may raise the opening/closing part 50 only for a predetermined time (short period of time), for example, after stopping the lowering of the opening/closing part 50 .

According to this, the shutter device 10 can prevent the foreign matter B from being drawn into the storage opening 21d by the opening/closing portion 50 that descends and entering the storage opening 21d. In addition, it is possible to prevent the opening/closing portion 50 and the foreign object B from being damaged by a load.

When the foreign object B is pushed downward by the slat 70 in the rear portion of the storage opening 21d, the foreign object B pushes the pushed portion 93a of the rear sensor 93, and the rear sensor 93 detects the foreign object B. In this case as well, the shutter device 10 stops the downward movement of the opening/closing portion 50 as in the case of the front sensor 92 . Then, the shutter device 10 raises the opening/closing portion 50 for a predetermined time (short time). As a result, it is possible to prevent the foreign matter B from entering from the rear portion of the storage opening 21d.

Further, the pressed portions 92a and 93a of the front sensor 92 and the rear sensor 93 according to the present embodiment are arranged in such a posture as to protrude obliquely upward. According to such a configuration, the projecting direction of the pressed portions 92a and 93a can be aligned with the direction of the load acting on the foreign object B, so that the pressed portions 92a and 93a are easily pressed by the foreign object B. Therefore, the foreign matter B can be detected with high accuracy by the front sensor 92 and the rear sensor 93 .

As described above, the uppermost slat 60 is arranged with a slight gap from the front wall portion 21b of the box body 21 in the fully opened state shown in FIG. In this configuration, the highest slat 60 swings or bends and is displaced downward when pressed from above by a person sitting thereon. The front projecting portion 61c and the rear projecting 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, respectively.

Thereby, the front side sensor 92 and the rear side sensor 93 detect the downward displacement of the uppermost slat 60 in the fully open state. The shutter device 10 prohibits the upward/downward movement of the opening/closing portion 50 by the detection. Thereby, it is possible to prevent the opening/closing part 50 from rising when the uppermost slat 60 is pressed from above. As a result, the opening/closing part 50 is prevented from rising against the pressing force from above, thereby preventing the opening/closing part 50 and the motor 111 from being overloaded.

Further, when the highest slat 60 is not displaced downward (not pressed from above), the front protruding portion 61c and the rear protruding portion 61d of the highest slat 60, the front sensor 92 and the 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 front projecting portion 61c and the rear projecting portion 61d can reliably press the pressed portions 92a and 93a. Therefore, 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), if a load higher than the load assumed for lowering the opening/closing portion 50 is applied to the motor 111, the lowering is performed. After stopping, the opening/closing part 50 is raised for a predetermined time (only for a short period of time). According to this, even if the detection unit 90 fails to detect the foreign object B and the foreign object B is caught between the opening/closing part 50 and the front wall part 21b, excessive load is applied to the motor 111 and the opening/closing part 50. can be suppressed.

The drainage structure of the storage box 20 will be described below with reference to FIGS. 14 to 16. FIG. 14(a), 15 and 16 are diagrams showing a cutaway portion of the storage box 20 where the case 22 is provided for the purpose of explaining the drainage structure.

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

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

The second discharge part 122 is for discharging the rainwater W that has entered the lower space S20. The second discharge part 122 is formed so as to penetrate the lower surface of the case 22 . The second discharge portion 122 is formed in the front portion (lower portion) of the lower surface of the case 22 . A plurality of the second ejection 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 unit 50 is moved up and down on a rainy day, as shown in FIG. ), rainwater W may enter. The rainwater W travels downward along the front wall portion 21 b and the vertical frame 30 and reaches the partition 23 . The rainwater W is guided rearward and downward along the inclined surface 23 a of the partition 23 and reaches the rear end portion of the partition 23 .

The rainwater W reaching the rear end of the partition 23 is flowed to the first discharge portion 121 and drops down the first discharge portion 121 . Thereby, the first discharge part 121 can discharge the rainwater W that has entered from the storage opening 21d to the outside of the storage box 20 from the upper space S10.

According to this, the first discharge part 121 can suppress rainwater W from accumulating in the upper space S10, so corrosion due to the rainwater W can be suppressed. In addition, since the rainwater W can be prevented from entering the lower space S20 from the upper space S10 by the partition 23, the rainwater W can be prevented from coming into contact with the motor 111. FIG.

In addition, rainwater W can be guided from the front space S11 to the first discharge portion 121 by using the inclined surface 23a. Thereby, the rainwater W can be easily discharged from the first discharge part 121 .

Here, the partition 23 is arranged at a position higher than the lower end portion of the slit 31 (straight portion 31 a ) of the vertical frame 30 . In addition, 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 enters the storage box 20 due to heavy rain or the like and the rainwater W cannot be completely discharged by the first discharge part 121, the rainwater W can be discharged from the straight part of the slit 31. 31 a , and gaps between the vertical frame 30 and the like and the partition 23 to escape downward. As a result, the storage box 20 can effectively prevent the rainwater W from accumulating in the upper space S10.

Further, as shown in FIG. 16, the rainwater W released downward from the straight portion 31a of the slit 31 and the like flows out into 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 , flows to the second discharge portion 122 , and drops through the second discharge portion 122 . Thereby, the second discharge part 122 can discharge the rainwater W released to the lower space S<b>20 to the outside of the storage box 20 .

According to this, the second discharge part 122 can suppress the rainwater W from accumulating in the rear space S12 even if the rainwater W escapes to the lower space S20. Therefore, corrosion due to rainwater W can be suppressed, and contact of rainwater W with the motor 111 can be suppressed.

The maintenance procedure for the storage box 20 will be described below with reference to FIGS. 17 and 18. FIG.

In the following, as shown in FIG. 17, the maintenance procedure will be described by exemplifying the case of removing a foreign object B that has entered the interior of the storage box 20. FIG.

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

As a result, the upper side of the upper space S10 is opened, and the foreign object B can be grasped by extending a hand from the upper side of the rear side space S12. Thus, 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 becoming an obstacle. can be maintained. Also, the foreign matter B can be removed by removing one slat 60 out 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, it is assumed that the foreign matter B cannot be removed only by removing the uppermost slat 60 and the rear blocking member 24 . Even in such a case, a space for removing the foreign matter B can be easily secured by removing some slats of the slat group 70 . Therefore, the storage box 20 can be easily maintained.

Further, in this embodiment, in addition to the uppermost slat 60 and the slat group 70, the interlocking member 80 and the partition 23 are also configured to be removable. Therefore, by removing all the slats 60 and 70, the interlocking member 80 and the partition 23, the motor 111 can be maintained from above. Therefore, the motor 111 can be easily maintained.

In addition, the box body 21 according to the present embodiment can remove the foreign matter B through the rear space S12 in which members are not particularly stored. In this way, the box body 21 can use the rear space S12 as a space for maintenance, so that the foreign matter B can be easily removed simply by removing the uppermost slat 60 and the rear closing member 24. . Also, the slat group 70 and the interlocking member 80 can be easily removed through the rear space S12. Thus, when the slat group 70 and the interlocking member 80 are removed, a relatively large space is left inside the box body 21 . Thus, the operator can easily access the large space inside the box body 21 from above the box body 21, for example. This allows the operator to easily maintain the storage box 20 . Furthermore, 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 blocking member 24, the rear sensors 93 attached to the rear blocking member 24 can also be removed together. Thereby, maintenance of the rear side sensor 93 can be performed easily.

Moreover, the partition 23 has 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 placed in the rear space S<b>12 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. a storage box 20 having an opening/closing portion 50 for switching between a state and a storage opening portion 21d (opening portion) opened upward and capable of storing the opening/closing portion 50 inside through the storage opening portion 21d; , and the uppermost slat 60 (the uppermost part of the opening/closing part 50) is formed larger than the storage opening 21d so as to block the storage opening 21d of the storage box 20 in the fully opened state. It is what is done.

With this configuration, it is possible to prevent rainwater W, foreign matter B, etc. from entering the storage box 20 in the fully open state.

It becomes possible to displace to By detecting the displacement of the highest slat 60 with the front sensor 92 and the rear sensor 93, it can be grasped that the highest slat 60 is pressed from above. In this case, if the up/down motion of the opening/closing portion 50 is restricted, it is possible to restrict the upward movement of the opening/closing portion 50 when the uppermost slat 60 is pressed from above in the fully open state.

Further, the uppermost slat 60 is provided with a front protrusion 61c and a rear protrusion 61d (projections) formed to protrude downward, and the front protrusion 61c and the rear protrusion 61d are , are formed in contact with the front side sensor 92 and the rear side sensor 93 in the fully open state.

By configuring in this manner, the front side projecting portion 61c and the rear side projecting portion 61d can be brought close to the front side sensor 92 and the rear side sensor 93 in advance in a state where the uppermost slat 60 is not pressed from above. can. According to this, the front side sensor 92 and the rear side sensor 93 can be reliably pressed by the front side protrusion 61c and the rear side protrusion 61d as the uppermost slat 60 is displaced. 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 assembly of a plurality of slats arranged in parallel in the vertical direction. The highest slat 60 among the plurality of slats is spaced apart from the slat 70 next to the highest in the fully opened state within the predetermined range. It is placed.

With this configuration, even if a foreign object B enters the storage box 20, it is possible to prevent the uppermost slat 60 from being pushed up by the foreign object B in the fully opened state. As a result, even if a foreign object B enters the storage box 20 in the fully opened state, the uppermost slat 60 can be placed in the original normal position.

Note that the storage opening 21d according to this embodiment is an embodiment of the opening according to the present invention.
Also, the top slat 60 according to this embodiment is an embodiment of the top part of the opening/closing part according to the present invention.
Further, the locking portion 61b according to this embodiment is an embodiment of the restricting means according to the present invention.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above configurations, and various modifications are possible within the scope of the invention described in the claims.

For example, the shutter device 10 is installed in the house 1, but the building in which the shutter device 10 is installed is not limited to the house 1, and may be a store, a commercial facility, or the like.

Further, the uppermost slat 60 does not necessarily have the engaging portion 61b, the front projecting portion 61c, and the rear projecting portion 61d as long as it can block the storage opening 21d in the fully opened state. The top slat 60 may be, for example, a simple flat plate member.

Further, although the uppermost slat 60 is arranged with a gap from the front wall portion 21b of the box body 21 in the fully opened state, it is not limited to this. It may be in contact with the portion 21b (see FIG. 19).

Also, the uppermost slat 60 contacts the front side sensor 92 and the rear side sensor 93 (that is, two sensors) in the fully open state, but it may contact one of the two sensors. That is, one of the two sensors may be arranged with a gap from the pressed portion (the pressed portion 92a or the pressed portion 93a). Further, if the topmost slat 60 can press at least one of the pressed portions 92a and 93a when pressed from above (for example, when a person sits on it), the pressed portions 92a and 93a can be pressed. may be spaced apart from each other (see FIG. 19).

FIG. 19 shows a top slat 160 according to the first modification. The topmost slat 160 is in contact with the front wall portion 21b of the box body 21 from above in the fully opened state, and is arranged with a gap from the front sensor 92 and the rear sensor 93. It differs from the topmost slat 60 according to the embodiment.

The uppermost slat 160 includes a body portion 161 and a beat 162 having a shorter length (front-rear width) than the beat 62 according to the present embodiment. The body portion 161 includes a flat surface 161a, a thick portion 161b, a front protrusion 161c, and a rear protrusion 161d.

The flat surface 161a is the upper surface of the main body 161 and is parallel to the horizontal surface. The thick portion 161b is a portion formed to be thicker than other portions. The thick portion 161 b is formed at the front end portion of the body portion 161 and contacts the front wall portion 21 b of the box body 21 . The front protruding portion 161c is formed to protrude rearward and downward from the rear lower end portion of the thick portion 161b, and is arranged with a gap in the rearward upper direction (forward and downward direction) from the pressed portion 92a of the front sensor 92. be done. The rear protruding portion 161d is formed to protrude forward and downward from the lower surface of the main body portion 161, and is arranged with a gap in the forward and upward direction (rear and downward direction) with respect to the pressed portion 93a of the rear sensor 93. be. The uppermost slat 160 is configured to be displaceable downward by arranging the rear end portion of the main body portion 161 with an upward gap with respect to the rear blocking member 24 . Further, the gap between the rear end portion of the main body portion 161 and the rear blocking member 24 is formed to be larger than the gap between the rear projection portion 161d and the pressed portion 93a of the rear sensor 93. As shown in FIG. That is, the gap between the rear protruding part 161d and the pressed part 93a of the rear sensor 93 is set so that the distance in the vertical direction is at least smaller than the gap between the rear end of the main body part 161 and the rear blocking member 24. formed apart.

As shown in FIG. 20, when the uppermost slat 160 is pressed from above by a person sitting thereon, it swings or bends, and the rear end portion of the main body portion 161 is displaced downward. The rear protrusion 161 d moves downward due to the displacement and presses the pressed portion 93 a of the rear sensor 93 . Thereby, the rear sensor 93 detects downward displacement of the top slat 160 in the fully open state. In this manner, the uppermost slat 160 displaces the rear end of the main body 161 downward rather than the front end of the main body 161, thereby minimizing the load on the front wall portion 21b. As a result, deformation of the front wall portion 21b can be suppressed. The top slat 160 is used in a situation where a person is expected to stand, for example, in a situation where the upper end of the box body 21 is arranged at substantially the same height as the indoor floor 4 and the outdoor floor 8 as in this embodiment. It is preferred to be used in

As described above, the uppermost slat 160 is provided with a rear protrusion 161d (protrusion) formed to protrude downward. They are spaced apart so that the distance in the vertical direction is at least smaller than the gap between the rear end portion of the main body portion 161 and the rear closing member 24 .

With this configuration, the gap formed between the rear protrusion 161d and the pressed portion 93a of the rear sensor 93 allows the front protrusion 61c and the rear protrusion 61d to operate more effectively than in the case of the front protrusion 61c and the rear protrusion 61d. Therefore, it is possible to provide some leeway in detecting the displacement of the uppermost slat 160 . Therefore, in the fully open state, it is possible to accurately detect that the highest slat 160 is being pressed from above, and the highest slat 160 swings or bends to a degree that is not detectable. Detecting the displacement of the uppermost slat 160 in this case can be suppressed.

In addition, although the uppermost slat 60 abuts on the outdoor ceiling 9 in the fully closed state, it is not limited to this. It may be arranged at the same position (see FIG. 21).

FIG. 21 shows the top slat 260 and the outdoor ceiling 209 according to the second modification. The top slat 260 differs from the top slat 60 according to the present embodiment in that the length of the beat 262 (vertical width in FIG. 21) is long. The outdoor ceiling 209 differs from the outdoor ceiling 9 according to the present embodiment in that it has a concave portion 209a. The recess 209 a is formed in the lower surface of the outdoor ceiling 209 . Also, the concave portion 209a is configured to be able to accommodate the beat 262 .

When the uppermost slat 260 is fully closed, the tip (upper end) of the beat 262 enters the concave portion 209a. The bead 262 is slightly spaced from the recess 209a. In this manner, the opening/closing portion 50 of the shutter device 10 enters the recess 209a formed in the outdoor ceiling 9 when the opening of the sash 7 is closed.

With such a configuration, it is possible to prevent birds, rainwater, and the like from entering between the uppermost slat 260 and the outdoor ceiling 209 . In addition, since no gap is formed between the outdoor ceiling 209 and the beat 262 when viewed from the front (in the front-rear direction), it is possible to prevent outdoor light from entering the room.

Further, in the second modified example, the configuration is such that the beat 262 is inserted into the concave portion 209a, but another configuration can also be adopted. For example, on the lower surface of the outdoor ceiling 209, a convex portion (for example, an upper rail) is formed that protrudes downward from the lower surface. It is also possible to move the tip (upper end) of the beat 262 immediately. Thus, in the second modification in which the top slat 260 is arranged with a slight gap with respect to the outdoor ceiling 209, at least a part of the top slat 260 is the side wall of the concave portion 209a or the convex portion. and overlap in front view. As described above, the recess according to the present invention is not limited to the portion recessed upward from the lower surface of the outdoor ceiling 209, but may be configured by the lower surface of the outdoor ceiling 209 and a surface that is displaced from the lower surface in the vertical direction. good. Specifically, the concave portion according to the present invention includes not only the concave portion 209a but also the lower surface of the outdoor ceiling 209 and a convex portion (for example, an upper crosspiece) that protrudes downward from the lower surface of the outdoor ceiling 209. is also included.

Moreover, although the uppermost slat 60 and the interlocking member 80 are arranged with a gap between them and the slat group 70, they may be stacked on the slat group 70 without any gap. By configuring in this way, the space for housing the opening/closing part 50 can be reduced, so that the shutter device 10 can be miniaturized.

Moreover, although the opening/closing part 50 is provided with a plurality of slats 60 and 70, the structure of the opening/closing part 50 is not limited to this as long as the building opening 6 can be opened and closed. The opening/closing part 50 may comprise, for example, one sheet-like member.

Further, the front side sensor 92 and the rear side sensor 93 are not limited to tape switches as long as they can detect a foreign object B that enters inside the storage opening 21d, and may be, for example, an infrared sensor or the like. may

Further, the postures of the pressed portions 92a and 93a of the front sensor 92 and the rear sensor 93 are not limited to those of the present embodiment as long as they can be pressed by the foreign object B entering the inside of the storage opening 21d. . For example, the pressed portions 92a and 93a may be arranged in a posture facing the front-rear direction.

Further, the shutter device 10 is configured to stop and raise the opening/closing portion 50 when the front sensor 92 and the rear sensor 93 detect the foreign object B, but the control when the foreign object B is detected is as follows. is not limited to For example, the shutter device 10 may only stop the downward movement of the opening/closing portion 50 when the foreign object B is detected.

The configuration of the interlocking member 80 is not limited to the present embodiment as long as it can block the storage opening 21d in the fully closed state. A configuration such as 380 is also possible.

The interlocking member 380 according to the modification differs from the interlocking member 80 according to the present embodiment in that it includes a receiving portion 381 , a front side beat 382 and a rear side beat 383 . The receiving portion 381 is formed at the rear portion of the interlocking member 380 . The receiving portion 381 is formed in a substantially L shape having a portion extending downward and a portion extending substantially rearward from the end of the portion extending downward. The front side beat 382 and the rear side beat 383 are configured to be elastically deformable by a substantially plate-shaped resin. The front beat 382 is provided at the front end portion of the interlocking member 380 with its plate surface facing forward and upward (rear and downward), and is arranged behind the front wall portion 21b. The rear beat 383 is provided at the rear end portion of the receiving portion 381 with its plate surface directed substantially in the front-rear direction, and is arranged below the rear closing member 24 . The rear portion of the interlocking member 380 is formed in a substantially J-shape in a side view by the receiving portion 381 and the rear side beat 383 .

The interlocking member 380 according to the modified example elastically deforms the front side beat 382 to apply a load to the foreign matter B even if the foreign matter B is caught between the front end portion (the front side beat 382) and the front wall portion 21b during elevation. can be suppressed. Further, even if a foreign object B is caught between the rear end portion (rear beat 383) and the rear closing member 24 when the interlocking member 380 is raised, the rear beat 383 is elastically deformed so that the foreign object B is loaded. This can be suppressed. Further, the interlocking member 380 can hold the foreign matter B by the receiving portion 381b and the rear side beat 383 even if the foreign matter B falls from the rear of the storage opening 21d in the fully closed state. As a result, the foreign matter B can be prevented from falling below the interlocking member 380, and the foreign matter B can be easily removed.

Further, the interlocking member 380 according to the modification has a smaller gap between the front end portion (front side beat 382) and the front wall portion 21b than in the present embodiment. As a result, in the fully closed state, it is possible to effectively prevent foreign matter B and rainwater W from entering the storage box 20 through the storage opening 21d.

Also, the member that closes the storage opening 21d in the fully closed state is not necessarily the interlocking member 80, and may be, for example, the slats of the slat group 70. FIG.

FIGS. 23 and 24 show an opening/closing part 450 according to a modification in which the slats of the slat group 70 block the storage opening 21d in the fully closed state. The opening/closing part 450 according to the modified example closes the storage opening 21d by utilizing not only the up-and-down motion of the slats but also the rotation motion.

Specifically, the opening/closing part 450 according to the modified example shown in FIG. The slats of the normal slat group 460 are formed in the same shape as the slats of the slat group 70 according to this embodiment. The front blocking slat 470 is the third slat from the bottom among all the slats 60, 460, 470, 480. The front blocking slat 470 differs from the slats of the normal slat group 460 in that it has a plate-like blocking part 471 projecting upward from its front end. The rear blocking slat 480 is the lowest slat. The rear blocking slat 480 includes a plate-shaped first blocking portion 481 projecting rearward from its rear end, and a plate-shaped second blocking portion 482 projecting rearward and downward from its rear end. It differs from the slats of the normal slat group 460 . In addition, the front blocking slat 470 and the rear blocking slat 480 are configured to be vertically movable and rotatable together with the normal slat group 460 .

As the front blocking slat 470 rotates, the plate surface of the blocking portion 471 faces up and down and abuts against the front wall portion 21b of the box body 21 to block the front portion of the storage opening 21d. In addition, the rear blocking slat 480 rotates below the storage opening 21d, and its plate surface faces the front-rear direction (stands up). The plate surface of the first closing portion 481 is directed in the front-rear direction by the rotation of the rear-side closing slat 480 and faces the rear-side closing member 24 . The plate surface of the second closing portion 482 faces upward (rearward and downward), and the rear upper end thereof is disposed near the rear closing member 24 . The rear blocking slat 480 blocks the rear portion of the storage opening 21 d with the first blocking portion 481 and the second blocking portion 482 . In this way, the opening/closing part 450 can close the storage opening 21d in the fully closed state by utilizing the pivoting motion of the two slats 470 and 480. As shown in FIG.

As described above, in the modified example, the opening/closing portion 450 is an assembly of a plurality of slats 60, 460, 470, and 480 arranged in parallel in the vertical direction. - It is formed using some slats 470 and 480 out of 470 and 480.

With this configuration, it is possible to suppress rainwater W, foreign matter B, etc. from entering the storage box 20 with a simple configuration using the slats 60, 460, 470, and 480. FIG.

In a modification, each of the plurality of slats 60, 460, 470, and 480 is configured to be able to switch its posture between a standing state, which is a standing state, and a lying state, which is a lying state. By switching the front side blocking slat 470 and the rear side blocking slat 480 (the part of the slats) to the raised state, the storage opening 21d of the storage box 20 is closed.

With this configuration, it is possible to suppress rainwater W, foreign matter B, etc. from entering the storage box 20 by a simple configuration using the switching (rotational motion) of the postures of the slats 470 and 480. can.

Also, the front blocking slat 470 and the rear blocking slat 480 are at least two or more slats 470 and 480 .

By configuring in this way, it is possible to suppress rainwater W, foreign matter B, etc. from entering the storage box 20 with a simple configuration using the switching of the postures of the slats 470 and 480 .

In addition, in a modification, the opening/closing part 450 may close the storage opening 21d by using the rotating motion of one slat.

In addition, in the modified example, the slats of the normal slat group 460 are interposed between the front blocking slat 470 and the rear blocking slat 480, but this is not a limitation, and the slats are adjacent to each other. may be

Moreover, in the shutter device 10, at least the rear closing member 24 should be detachable, and the opening/closing part 50, the interlocking member 80 and the partition 23 do not necessarily have to be detachable.

Further, the motor 111 is not particularly limited in its arrangement position as long as it is configured to be able to drive the opening/closing part 50, and may be arranged in front of the opening/closing part 50, for example. Also, the motor 111 may be mounted on the case 22 .

Further, inside the box main body 21, the front space S11 and the rear space S12 do not necessarily have to be adjacent to each other, and may be connected via another space, for example.

In addition, although the drainage structure is provided with the first discharge part 121 and the second discharge part 122, the structure of the drainage structure is limited to this as long as the rainwater W that has entered the storage box 20 can be discharged. not something. The drainage structure may be, for example, a configuration like the drainage structure according to the first modified example shown in FIG. 25 or the drainage structure according to the second modified example shown in FIG.

As shown in FIG. 25, the drainage structure according to the first modified example differs from the drainage structure according to the present embodiment in that a first discharge portion 521 is provided. The first discharge part 521 is for discharging the rainwater W that has entered the upper space S10 from the front part of the storage box 20 . Also, the first discharge portion 521 is a gap formed between the inner surface of the front wall portion 21 b and the case 22 and the partition 23 . The first discharge part 521 is formed such that its upper end is located above the partition 23 and communicates with the upper space S10.

According to the drainage structure according to the first modification, the rainwater W that enters from the storage opening 21d and runs along the front wall portion 21b can be moved to the first discharge portion 521 and discharged to the outside. As a result, the rainwater W can be drained (quickly) without passing through the inclined surface 23a of the partition 23, so that drainage can be improved.

Moreover, the drainage structure according to the first modified example can effectively improve the drainage performance by combining it with the interlocking member 380 according to the modified example shown in FIG. Specifically, the interlocking member 380 has a smaller gap between the front end portion (front side beat 382) and the front wall portion 21b than in the present embodiment. Therefore, when the rainwater W enters the upper space S10 in the fully closed state, the rainwater W moves along the front side beat 382 to the front wall portion 21b, and easily travels along the front wall portion 21b. Therefore, when the drainage structure according to the first modified example and the interlocking member 380 according to the modified example are combined, the rainwater W that has become easier to run along the front wall portion 21b with the interlocking member 380 can be quickly discharged from the first discharge portion 521. Therefore, it is possible to effectively improve the drainage performance.

As shown in FIG. 26, the drainage structure according to the second modification differs from the drainage structure according to the present embodiment in that a first discharge portion 621 and a second discharge portion 622 are provided. The first discharge portion 621 is for discharging the rainwater W that has entered the upper space S10 from the right portion of the storage box 20 . Also, the first discharge portion 621 is a notch portion formed at the right end portion of the partition 23 . The first discharge portion 621 is formed in a substantially rectangular shape in plan view. The first discharge portion 621 is formed from the front end portion of the partition 23 to the rear portion (the portion located behind the attachment 40). The second discharge portion 622 is for discharging rainwater W that has entered the lower space S20 from the right portion of the storage box 20 . Also, the second discharge portion 622 is a notch formed in the bottom surface of the case 22 . The second discharge portion 622 is formed in substantially the same shape as the first discharge portion 621 and is formed so as to overlap the first discharge portion 621 in plan view.

According to the drainage structure according to the second modified example, the rainwater W that enters from the storage opening 21d and travels along the vertical frame 30 and the attachment 40 is guided downward by the first discharge portion 621 and the second discharge portion 622 to be discharged to the outside. can be discharged to As a result, the rainwater W can be drained (quickly) without passing through the inclined surface 23a of the partition 23, so that drainage can be improved.

In this way, the position where the first discharge part 121 is formed is not particularly limited as long as the first discharge part 121 can discharge the rainwater W in the front space S11. Further, the position where the second discharge part 122 is formed is not particularly limited as long as the second discharge part 122 can discharge the rainwater W in the lower space S20.

Moreover, the shutter device 10 only needs to be formed with at least the first discharge portion 121 and does not necessarily need to be formed with the second discharge portion 122 .

Moreover, in the house 1, the fitting provided at the building opening 6 does not necessarily have to be a sweep-out sash.

Further, in the house 1, the shutter device 10 does not necessarily need to block the storage opening 21d in the fully open state and the fully closed state.

In addition, in the house 1, the storage opening 21d of the shutter device 10 is assumed to be at substantially the same height as the indoor floor 4, but is not limited to this. may be

In addition, in the house 1, the outdoor floor 8 does not necessarily have to have substantially the same height as the indoor floor 4, and they may have different heights.
