  The inclined surface 61a is the upper surface of the main body 61. The inclined surface 61a is formed so as to be inclined downward as going forward. A plurality of recesses are formed on the inclined surface 61a at intervals in the front-rear direction. Thus, when a person is placed on the uppermost slat 60, the inclined surface 61a is made difficult to slip (functions as a non-slip).

  The locking portion 61b is for restricting deformation of the front wall portion 21b of the box body 21. The locking portion 61b is formed to protrude downward from the front end of the main body 61. The locking portion 61b is formed from the left end to the right end of the main body 61. The locking portion 61b faces the front wall 21b.

  The front protruding portion 61c is for pressing the pressed portion 92a of the front sensor 92. The front protruding portion 61c is formed to protrude rearward and downward from the lower surface of the main body 61. The front protruding portion 61c has a middle portion in the upper and lower portions lightly in contact with the pressed portion 92a of the front sensor 92 so that the front sensor 92 does not react (to the extent that the pressed portion 92a is not pressed). Thus, the front protruding portion 61c is arranged in a state of being in contact with the pressed portion 92a of the front sensor 92.

  The rear protrusion 61d is for pressing the pressed portion 93a of the rear sensor 93. The rear protrusion 61d is formed to protrude forward and downward from the lower surface of the main body 61. The rear protruding portion 61d is lightly in 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 a state of being in contact with the pressed portion 93a of the rear sensor 93.

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

  The uppermost slat 60 configured in this manner is arranged with a slight gap above the upper end of the front wall 21b of the box body 21. The uppermost slats 60 are 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 slats 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 and 7 to 11. In the following, the operation of the shutter device 10 will be described with an example of 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. Thereby, the lower lifting member 114, the upper lifting member 115, the connecting member 116, and the uppermost arm member 101 are raised. At this time, the upper elevating member 115 rises while the pin 115a slides on the straight portion 31a while maintaining the posture shown in FIG. Thus, the uppermost slat 60 rises without pivoting. The storage opening 21d is opened by raising the uppermost slat 60.

  When the uppermost slat 60 rises, the longitudinal direction of the link member 102 that connects the uppermost slat 60 and the slat 70 adjacent below (hereinafter, referred to as “one slat 70 below”) rises and falls. Rotate to face. Then, when the link member 102 can no longer rotate (rotates until the rotation is restricted by the restricting means), the arm member 101 connected to the lower slat 70 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 above the front space S11. In this way, the slats 60 and 70 arranged upward are sequentially raised. When the lowermost slats 70 of the slat group 70 are raised by the raising, the interlocking member 80 is raised 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. Is done. The lower rear portion of the upper elevating member 115 is pressed by the ascending lower elevating member 114 so as to rotate about the pin 115a. Thus, the upper elevating member 115 is rotated counterclockwise in FIG. 10 with the movement of the pin 115a. When the upper elevating member 115 starts to rotate, the front end of the arm member 101 is pushed downward, and the arm member 101 rotates counterclockwise in FIG. In this way, as shown in FIG. 11, the uppermost slat 60 and the slat group 70 are rotated about 90 degrees in the counterclockwise direction, and the plate surface thereof is oriented in the front-rear direction. As a result, the posture of the uppermost slat 60 and the slat group 70 is changed from a state in which the plate surface is oriented vertically (lying down) to a state in which the plate surface is oriented forward and backward (standing). As a result, the shutter device 10 completely closes the building opening 6 (switches to the fully closed state).

  Note that the interlocking member 80 does not rotate due to the rotation of the arm member 101, and is disposed inside the storage opening 21d with its plate surface facing up and down in the fully closed state. Thereby, the interlocking member 80 can close the storage opening 21d in the fully closed state. According to this, in the fully closed state, it is possible to prevent foreign matter B, rainwater, and the like from entering the storage box 20 through the storage opening 21d. 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 some gap. I have.

  In addition, the shutter device 10 can easily close the storage opening 21d by using the non-rotatable interlocking member 80 to close the storage opening 21d by using the upward movement of the opening and closing unit 50. Further, 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 opening the building opening 6, the shutter device 10 drives the motor 111 to rotate the sprocket 112 in a direction opposite to the direction in which the building opening 6 is opened. As a result, the slat descends while rotating in the clockwise direction in FIG. 11 (the direction opposite to the case where the building opening 6 is opened) and opens the building opening 6.

  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 from the storage opening 21d. In the slat group 70, the link member 102 is folded and stacked vertically without any gap.

  On the other hand, as shown in FIGS. 5 and 6, the uppermost slat 60 is not stored in the front space S11 even when it is lowered, and the plate surface of the box main body 21 is oriented substantially vertically. It is arranged above. Thus, the uppermost slat 60 can close the storage opening 21d in the fully opened state. According to this, in the fully opened state, it is possible to prevent foreign matter B and rainwater from entering the storage box 20 via the storage opening 21d.

  Here, when the uppermost slat 60 is pressed from above by applying a person or the like in a fully opened state (a downward load is applied), the uppermost slat 60 is displaced downward by swinging or bending and displaced downward. 21 is in contact with the front wall 21b. The front wall portion 21b is pressed from above via the uppermost slat 60, and tends to be deformed so as to fall forward (the storage opening 21d expands). 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. Thereby, since the locking portion 61b can support the front wall portion 21b, the deformation of the front wall portion 21b can be restricted.

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

  Specifically, when the foreign matter B enters the gap between the uppermost slat 60 and the immediately lower slat 70, the foreign matter B is caught between the uppermost slat 60 and the immediately lower slat 70. It is possible to suppress the uppermost slat 60 from being pushed up.

  Also, even if the foreign matter B is sandwiched between two adjacent slats in the slat group 70 and the slat group 70 is lifted, there is a gap between the uppermost slat 60 and the slat 70 below it in the fully opened state. The top slat 60 is not pushed up.

  In addition, the uppermost slat 60 can discharge foreign matter B and rainwater 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 61.

  As shown in FIGS. 1 and 2, the house 1 is provided with the shutter device 10 that closes the building opening 6 (sash 7) by ascending, so that the box body 21 (storage box 20) is attached to the sash 7. At the front lower portion of the indoor ceiling 5 and the ceiling surface of the outdoor ceiling 9 can be prevented from having a step. This makes it possible to form a flush ceiling surface from the indoor side to the outdoor side, so that the comfort of the resident of the house 1 can be improved.

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

  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. Thus, the box main body 21 prevents a step from being formed between the indoor floor 4 and the outdoor floor 8, and can form a flush floor surface from the indoor side to the outdoor side. Therefore, the comfort of the resident of the house 1 can be improved.

  In addition, as shown in FIG. 11, the beat 62 abuts on the outdoor ceiling 9 of the uppermost slat 60 in the fully closed state. Thus, the beat 62 closes the main body 61 and the outdoor ceiling 9 without a gap, and can improve the blocking property of the building opening 6. This can prevent birds, rainwater, and the like from entering between the uppermost slat 60 and the outdoor ceiling 9. In addition, it is possible to remove the discomfort that birds, rainwater, and the like may enter from between the uppermost slat 60 and the outdoor ceiling 9, and improve the comfort of the resident 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, there is no need to provide a frame or the like for receiving the uppermost slat 60. In this way, a sense of unity from the indoor side to the outdoor side on the ceiling surface can be created, and the comfort of the resident of the house 1 can be improved.

  Hereinafter, the control of the 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.

  The shutter device 10 includes a predetermined control unit capable of acquiring a detection result of the detection unit 90, and the control unit controls elevation 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 and upper part of the storage opening 21d. The shutter device 10 stops raising and lowering the opening and closing unit 50 based on the detection result of the upper sensor 91. Further, the shutter device 10 prohibits the opening / closing unit 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 above and behind the storage opening 21d (indoor side) comes into contact with the opening / closing section 50, or the foreign matter B is drawn into the storage opening 21d by the opening / closing section 50 that descends. Can be suppressed.

  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.

  The front sensor 92 and the rear sensor 93 detect the foreign matter B when the foreign matter B exists inside the storage opening 21d. Hereinafter, a case where the front sensor 92 detects the foreign matter B will be described with reference to FIGS. 12 and 13. In FIGS. 12 and 13, white arrows indicate the moving direction of the opening / closing unit 50. In FIG. 13, black arrows indicate the direction of the load acting on the foreign matter B.

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

  The foreign matter B is sandwiched between the front wall 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 matter B. When the foreign matter B is further pressed downward by the descending slat 70, a front-down load is applied to press the pressed portion 92a.

  Thereby, 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 of the opening / closing unit 50. After stopping the lowering of the opening / closing section 50, the shutter device 10 may raise the opening / closing section 50 for a predetermined time (short time), for example.

  According to this, the shutter device 10 can suppress that the foreign matter B is drawn into the storage opening 21d by the opening / closing unit 50 that descends, and the foreign matter B enters 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 slat 70 at the rear 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 unit 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). This can prevent foreign matter B from entering from the rear 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 disposed in such a manner as to project obliquely upward. According to such a configuration, since the protruding directions of the pressed portions 92a and 93a can be matched with the direction of the load acting on the foreign matter B, the pressed portions 92a and 93a are 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.

  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, when the uppermost slat 60 is pressed from above, for example, when a person is placed on it, it is displaced downward by swinging or bending. The front protruding portion 61c and the rear protruding portion 61d move downward by the displacement, and press the pressed portions 92a and 93a of the front sensor 92 and the rear sensor 93.

  Accordingly, the front sensor 92 and the rear sensor 93 detect the downward displacement of the uppermost slat 60 in the fully opened state. The shutter device 10 prohibits the opening / closing unit 50 from moving up and down based on the detection. Thus, when the uppermost slat 60 is pressed from above, the opening / closing section 50 can be prevented from rising. This prevents the opening / closing section 50 from rising against the pressing force from above, thereby preventing a load from being applied to the opening / closing section 50 and the motor 111.

  When the uppermost slat 60 is not displaced downward (not pressed from above), the front protrusion 61c and the rear protrusion 61d of the uppermost slat 60, the front sensor 92, and the rear sensor The pressed portions 92 a and 93 a 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 protrusion 61c and the rear protrusion 61d. Therefore, the downward displacement of the uppermost slat 60 can be accurately detected.

  Further, in the shutter device 10, when the opening / closing section 50 is lowered (when the building opening 6 is opened) and a load higher than the load expected to lower the opening / closing section 50 is applied to the motor 111, the lowering is performed. It stops and raises the opening / closing part 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 and closing unit 50 and the front wall 21b, an excessive load is applied to the motor 111 and the opening and closing unit 50. Can be suppressed.

  The drainage structure of the storage box 20 will be described below with reference to FIGS. FIGS. 14A, 15 and 16 are sectional views of the storage box 20 in which the case 22 is provided for explanation of 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 part 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 formed by a gap formed between the rear end of the bottom 21 a of the box body 21, the rear end of the case 22 and the rear end of the partition 23, and the base 2. is there. The first discharge portion 121 is formed by arranging the storage box 20 (box body 21) at a slight distance in front of the base 2.

  The second discharge part 122 is for discharging the rainwater W that has entered the lower space S20. The second discharge portion 122 is formed to penetrate the lower surface of the case 22. The second discharge portion 122 is formed at a front portion (lower portion) on the lower surface of the case 22. The 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 faces upward, when the opening / closing unit 50 is moved up and down on a rainy day, the shutter device 10 is moved from the storage opening 21d to the inside of the storage box 20 (the upper space S10) as shown in FIG. ) May enter 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 rearward and downward along the inclined surface 23 a of the partition 23, and reaches the rear end of the partition 23.

  The rainwater W that has reached the rear end of the partition 23 flows to the first drain 121 and falls down the first drain 121. Thereby, the first discharge part 121 can discharge the rainwater W that has entered through the storage opening 21d from the upper space S10 to the outside of the storage box 20.

  According to this, since the first discharge part 121 can suppress accumulation of the rainwater W in the upper space S10, corrosion due to the rainwater W can be suppressed. Further, since the rainwater W can be prevented from entering the lower space S20 from the upper space S10 by the partition 23, it is possible to suppress the rainwater W from touching 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. Thereby, it is possible to easily discharge the rainwater W from the first discharge unit 121.

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

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

  Also, as shown in FIG. 16, the rainwater W that has escaped downward from the straight portion 31a of the slit 31 and the like flows out to the lower space S20. The rainwater W moves downward in the lower space S <b> 20 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 falls down the second discharge portion 122. Thereby, the second discharge part 122 can discharge the rainwater W released to the lower space S20 to the outside of the storage box 20.

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

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

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

  The foreign matter B illustrated in FIG. 17 falls from the storage opening 21d into the storage box 20, 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 blocking member 24 are removed.

  Thus, 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. Thus, the foreign matter B is removed from above the storage opening 21d. According to this, even when 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 being in the way. Can be maintained. If one of the slats 60, 70 is removed, the foreign matter B can be removed. 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, if some of the slats of the slat 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.

  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 configured to be removable. Therefore, if all the slats 60 and 70, the interlocking member 80, and the partition 23 are removed, the motor 111 can be maintained from above. Therefore, maintenance of the motor 111 can be easily performed.

  Further, the box main body 21 according to the present embodiment can remove the foreign matter B via the rear space S12 in which the members are not particularly stored. As described above, since the box body 21 can use the rear space S12 as a space for maintenance, the foreign matter B can be easily removed only by removing the uppermost slat 60 and the rear blocking member 24. . Further, the slat group 70 and the interlocking member 80 can be easily removed via the rear space S12. As described above, when the slat group 70 and the interlocking member 80 are removed, a relatively large space (space) is left inside the box body 21. Thus, the operator can easily access a large space inside the box main body 21 from above the box main body 21, for example. Thereby, the worker 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.

  In the present embodiment, by removing the rear blocking member 24, the rear sensor 93 attached to the rear blocking member 24 can be collectively removed. Thereby, the rear sensor 93 can be easily maintained.

  The partition 23 includes an inclined surface 23a that is inclined toward the rear (the rear space S12). According to the inclined surface 23a, the foreign matter B dropped on the partition 23 can be guided to the rear space S12. Thus, the foreign matter B can be easily arranged in the rear space S12 and can be 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 is in a fully closed state in which the building opening 6 is fully closed by ascending, and is fully opened in which the building opening 6 is fully opened by descending. A storage box 20 having an opening / closing section 50 for switching between a state and a state, a storage opening 21d (opening) opened upward, and capable of storing the opening / closing section 50 inside through 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 in the fully opened state. Is what is being done.

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

  Further, the uppermost slat 60 is provided with a locking portion 61b (restriction means) for restricting the storage opening 21d from being deformed so as to expand in the fully opened state.

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

  The locking portion 61b restricts the storage opening 21d from being deformed by being locked to the upper end of the storage box 20 (the front wall 21b of the box body 21) in the fully opened state. It is.

  With this configuration, it is possible to prevent the storage opening 20d of the storage box 20 from being deformed so as to be widened by a simple configuration in which the locking portion 61b is hooked on the upper end of the storage box 20.

  The uppermost slat 60 is disposed with a gap between the uppermost slat 60 and at least a part of the upper end of the storage box 20 in the fully opened state. A front sensor 92 and a rear sensor 93 (detection means) for detecting displacement are provided. When the front sensor 92 and the rear sensor 93 detect the displacement of the uppermost slat 60 in the fully opened state, The opening of the opening / closing section 50 is restricted.

  With this configuration, when the uppermost slat 60 is pressed from above in the fully opened state, it is possible to restrict the opening / closing section 50 from rising. Specifically, the uppermost slat 60 is disposed with a gap between the uppermost slat 60 and the upper end of the storage box 20, so that when a person is on the slat 60, the slat 60 is pressed from above to lower the storage box 20. Can be displaced. By detecting the displacement of the uppermost slat 60 with the front sensor 92 and the rear sensor 93, it can be grasped that the uppermost slat 60 is pressed from above. In this case, if the vertical movement of the opening / closing section 50 is restricted, it is possible to restrict the upward movement of the opening / closing section 50 when the uppermost slat 60 is pressed from above in the fully opened state.

  The uppermost slat 60 is provided with a front protrusion 61c and a rear protrusion 61d (projection) formed to protrude downward, and the front protrusion 61c and the rear protrusion 61d are , In the fully opened state, the front sensor 92 and the rear sensor 93 are in contact with each other.

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

The uppermost slat 60 according to the present embodiment is an embodiment of the lid according to the present invention.

  As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above configuration, and various changes can be made within the scope of the invention described in the claims.

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

  In addition, the uppermost slat 60 does not necessarily need to include the locking portion 61b, the front protruding portion 61c, and the rear protruding portion 61d as long as it can close the storage opening 21d in the fully opened state. The uppermost slat 60 may be, for example, a simple flat plate-shaped member.

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

  In addition, the uppermost slat 60 contacts the front sensor 92 and the rear sensor 93 (that is, two sensors) in the fully opened state, but may contact one of the two sensors. That is, one of the two sensors may be arranged with a gap from the pressed part (the pressed part 92a or the pressed part 93a). When the uppermost slat 60 can be pressed from at least one of the pressed portions 92a and 93a when the uppermost slat 60 is pressed from above (for example, when a person is placed), the pressed portions 92a and 93a (See FIG. 19).

  FIG. 19 shows the uppermost slat 160 according to the first modification. The uppermost 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 disposed with a gap between the front sensor 92 and the rear sensor 93. This is different from the uppermost slat 60 according to the embodiment.

  The uppermost slat 160 includes a main body 161 and a beat 162 having a shorter length (width in the front-rear direction) than the beat 62 according to the present embodiment. The main body 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 a surface parallel to the horizontal plane. The thick part 161b is a part formed to be thicker than other parts. The thick portion 161b is formed at the front end of the main body 161 and contacts the front wall 21b of the box main 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 rear upper direction (front lower direction) with respect to the pressed portion 92a of the front sensor 92. Is done. The rear protruding portion 161d is formed so as to protrude forward and downward from the lower surface of the main body 161 and is arranged with a gap in the front upper direction (rear lower direction) with respect to the pressed portion 93a of the rear sensor 93. You. The uppermost slat 160 is configured to be displaceable downward by arranging the rear end of the main body 161 with a gap above the rear closing member 24. The gap between the rear end of the main body 161 and the rear blocking member 24 is formed to be larger than the gap between the rear protruding portion 161d and the pressed portion 93a of the rear sensor 93. That is, the gap between the rear protruding portion 161d and the pressed portion 93a of the rear sensor 93 is such that the vertical distance is at least smaller than the gap between the rear end portion of the main body 161 and the rear closing member 24. It is formed apart.

  As shown in FIG. 20, when the uppermost slat 160 is pressed from above, for example, when a person is put on it, it swings or bends, and the rear end of the main body 161 is displaced downward. The rear protruding portion 161d moves downward due to the displacement, and presses the pressed portion 93a of the rear sensor 93. As a result, the rear sensor 93 detects the downward displacement of the uppermost slat 160 in the fully open state. As described above, the uppermost slat 160 displaces the rear end of the main body 161 downward, not the front end of the main body 161, so that a load is not applied to the front wall 21 b as much as possible. Thereby, the deformation of the front wall portion 21b can be suppressed. The top slat 160 is a situation in which a person is assumed to be placed, for example, a situation in which 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 the present embodiment. It is preferable to use in.

  As described above, the uppermost slat 160 is provided with the rear protruding portion 161d (protruding portion) formed so as to protrude downward, and the rear protruding portion 161d communicates with the rear sensor 93 in the fully opened state. It is formed so that the vertical distance is at least smaller than the gap between the rear end of the main body 161 and the rear closing member 24.

  With such a configuration, the gap formed between the rear protruding portion 161d and the pressed portion 93a of the rear sensor 93 makes it possible to compare with the front protruding portion 61c and the rear protruding portion 61d as described above. Thus, it is possible to provide some latitude in detecting the displacement of the uppermost slat 160. For this reason, in the fully opened state, it is possible to accurately detect that the uppermost slat 160 is pressed from above, and the uppermost slat 160 does not swing to the degree of detection but swings or bends. In this case, the detection of the displacement of the uppermost slat 160 can be suppressed.

  In addition, the uppermost slat 60 is assumed to abut on the outdoor ceiling 9 in the fully closed state. However, the present invention is not limited to this. (See FIG. 21).

  FIG. 21 shows a top slat 260 and an outdoor ceiling 209 according to the second modification. The uppermost slat 260 is different from the uppermost slat 60 according to the present embodiment in that the length of the beat 262 (the vertical width in FIG. 21) is long. The outdoor ceiling 209 is different from the outdoor ceiling 9 according to the present embodiment in that the outdoor ceiling 209 includes a concave portion 209a. The recess 209 a is formed on the lower surface of the outdoor ceiling 209. In addition, the concave portion 209a is configured to be able to store the beat 262.

  In the uppermost slat 260, the tip (upper end) of the beat 262 enters the recess 209a in the fully closed state. The beat 262 is arranged slightly apart from the recess 209a. Thus, when the opening / closing section 50 of the shutter device 10 is closed with respect to the opening of the sash 7, the opening / closing section 50 enters the recess 209 a formed in the outdoor ceiling 9.

  According to such a configuration, entry of birds, rainwater, and the like from between the uppermost slat 260 and the outdoor ceiling 209 can be suppressed. In addition, since no gap is formed between the outdoor ceiling 209 and the beat 262 in a front view (front-rear direction), it is possible to prevent outdoor light from entering the indoor.

  In the second modification, the beat 262 is inserted into the recess 209a. However, another configuration can be adopted. For example, a convex portion (for example, an upper crosspiece) that protrudes downward from the lower surface is formed on the lower surface of the outdoor ceiling 209, and in a fully closed state, the front portion (outdoor side) or the rear portion (indoor side) of the convex portion. Alternatively, the tip (upper end) of the beat 262 may be moved. As described above, in the second modified example in which the uppermost slat 260 is arranged with a slight gap with respect to the outdoor ceiling 209, at least a part of the uppermost slat 260 is formed by the concave portion 209a or the side wall of the convex portion. Should just overlap in front view. As described above, the concave portion according to the present invention includes not only a portion recessed upward from the lower surface of the outdoor ceiling 209 but also a lower surface of the outdoor ceiling 209 and a surface vertically displaced from the lower surface. Good. Specifically, the concave portion according to the present invention includes, in addition to the concave portion 209a, a portion configured by a lower surface of the outdoor ceiling 209 and a convex portion (for example, an upper crosspiece) that protrudes downward from the lower surface. Is also included.

  Although the uppermost slat 60 and the interlocking member 80 are arranged with a gap between the slat group 70 and the slat group 70, they may be stacked without any gap on the slat group 70. With this configuration, the space for housing the opening / closing section 50 can be reduced, so that the shutter device 10 can be downsized.

  In addition, the opening / closing unit 50 includes the plurality of slats 60 and 70, but the configuration of the opening / closing unit 50 is not limited to this as long as the opening 6 can be opened and closed. The opening / closing section 50 may include, for example, one sheet-shaped member.

  Further, the configuration of the front sensor 92 and the rear sensor 93 is not limited to the tape switch as long as the foreign matter B entering the inside of the storage opening 21d can be detected. You may.

  In addition, as long as the pressed portions 92a and 93a of the front sensor 92 and the rear sensor 93 can be pressed by the foreign matter B entering the inside of the storage opening 21d, the posture is not limited to the present embodiment. . The pressed portions 92a and 93a may be arranged, for example, in a posture facing the front-rear direction.

  The shutter device 10 stops and lowers the lowering of the opening / closing unit 50 when the front sensor 92 and the rear sensor 93 detect the foreign matter B. However, the present invention is not limited to this. The shutter device 10 may, for example, only stop the lowering of the opening / closing unit 50 when the foreign matter B is detected.

  The configuration of the interlocking member 80 is not limited to the present embodiment as long as the interlocking member 80 can close the storage opening 21d in the fully closed state. For example, the interlocking member according to the modification shown in FIG. A configuration like 380 is also possible.

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

  The interlocking member 380 according to the modified example elastically deforms the front beat 382 and applies a load to the foreign matter B even if the foreign matter B is caught between the front end portion (front beat 382) and the front wall portion 21b at the time of elevating. Can be suppressed. Further, the interlocking member 380 elastically deforms the rear beat 383 and applies a load to the foreign matter B even when the foreign matter B is caught between the rear end portion (the rear beat 383) and the rear closing member 24 when ascending. This can be suppressed. Further, the interlocking member 380 can hold the foreign matter B by the receiving portion 381b and the rear beat 383 even if the foreign matter B falls from behind the storage opening 21d in the fully closed state. Accordingly, it is possible to prevent the foreign matter B from dropping below the interlocking member 380, and to easily remove the foreign matter B.

  In the interlocking member 380 according to the modified example, the gap between the front end portion (front beat 382) and the front wall portion 21b is smaller than in the present embodiment. Accordingly, in the fully closed state, it is possible to effectively prevent foreign matter B and rainwater W from entering the storage box 20 from the storage opening 21d.

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

  FIGS. 23 and 24 show an opening / closing section 450 according to a modification in which the storage opening 21d is closed in the fully closed state by the slats of the slat group 70. FIG. The opening / closing unit 450 according to the modification closes the storage opening 21d by using the rotation operation in addition to the slat lifting / lowering operation.

  Specifically, the opening / closing unit 450 according to the modified example shown in FIG. 23 includes a top slat 60, a normal slat group 460, a slat 470 for front obstruction, and a slat 480 for rear obstruction. The slats of the normal slat group 460 are formed in the same shape as the slats of the slat group 70 according to the present embodiment. The anterior obstructing slat 470 is the third slat from the bottom of all the slats 60, 460, 470, 480. The front-side closing slats 470 are different from the slats of the normal slat group 460 in that the front-side closing slats 470 have a plate-like closing portion 471 protruding upward from the front end. The posterior obstruction slat 480 is the lowest slat. The rear blocking slat 480 is provided with a plate-shaped first blocking portion 481 protruding rearward from the rear end portion, and a plate-shaped second blocking portion 482 protruding rearward downward from the rear end portion. It differs from the slats of the normal slat group 460. Further, the front-side closing slats 470 and the rear-side closing slats 480 are configured to be able to move up and down together with a normal slat group 460 and to be rotatable.

  As shown in FIG. 24, in the opening / closing unit 450 according to the modification, in the fully closed state, the front-side closing slat 470 is rotated above the storage opening 21 d, and its plate surface is oriented in the front-rear direction (upright). ) State. The rotation of the front-side closing slat 470 causes the plate surface of the closing portion 471 to be turned up and down to abut on the front wall portion 21b of the box body 21 and close the front portion of the storage opening 21d. Further, the rear closing slat 480 is rotated below the storage opening 21d, and the plate surface thereof is in the front-rear direction (up). The first closing portion 481 faces the rear closing member 24 by turning the rear closing slat 480 so that the plate surface thereof is oriented in the front-rear direction. The second closing portion 482 has a plate surface directed forward and upward (rear and lower), and a rear upper end portion is disposed near the rear closing member 24. The rear closing slat 480 closes the rear portion of the storage opening 21d by the first closing portion 481 and the second closing portion 482. In this way, the opening / closing section 450 can close the storage opening 21d in the fully closed state by using the rotating operation of the two slats 470 and 480.

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

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

  In a modified example, the plurality of slats 60, 460, 470, and 480 are configured to be capable of switching their posture between a rising state, which is a rising state, and a lying state, which is a lying state, and The front opening slats 470 and the rear closing slats 480 (partial slats) are switched to the rising state to close the storage opening 21d of the storage box 20.

  With this configuration, it is possible to suppress rainwater W, foreign matter B, and the like from entering the inside of the storage box 20 with a simple configuration using the switching (rotational operation) of the posture of the slats 470 and 480. it can.

  The front obstructing slats 470 and the rear obstructing slats 480 are at least two or more slats 470 and 480.

  With such a configuration, it is possible to suppress rainwater W, foreign matter B, and the like from entering the inside of the storage box 20 with a simple configuration using the switching of the posture of the slats 470 and 480.

  In the modification, the opening / closing unit 450 may close the storage opening 21d by using the rotation operation of one slat.

  Further, in the modified example, the slats of the normal slat group 460 were interposed between the slats 470 for front occlusion and the slats 480 for back occlusion, but the present invention is not limited to this. May be.

  Further, in the shutter device 10, it is sufficient that at least the rear blocking member 24 is removable, and the opening / closing unit 50, the interlocking member 80, and the partition 23 do not necessarily need to be provided in a removable manner.

  In addition, as long as the motor 111 is configured to be able to drive the opening / closing section 50, the position of the motor 111 is not particularly limited. For example, the motor 111 may be arranged in front of the opening / closing section 50 or the like. Further, 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.

  Further, the drainage structure includes the first discharge part 121 and the second discharge part 122, but the configuration of the drainage structure is not 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 configured, for example, like the drainage structure according to the first modification shown in FIG. 25 or the drainage structure according to the second modification shown in FIG.

  As shown in FIG. 25, the drainage structure according to the first modification is different from the drainage structure according to the present embodiment in that the drainage structure according to the first modification includes a first discharge portion 521. 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. The first discharge portion 521 is a gap formed between the inner surface of the front wall portion 21b and the case 22 and the partition 23. The first discharge portion 521 is formed so 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 has entered the storage opening 21d and travels along the front wall 21b can be moved to the first drain 521 and discharged to the outside. Thereby, since the rainwater W can be discharged (quickly) without passing through the inclined surface 23a of the partition 23, the drainage property can be improved.

  In addition, the drainage structure according to the first modification can effectively improve drainage by combining with the interlocking member 380 according to the modification shown in FIG. Specifically, in the interlocking member 380, the gap between the front end (the front beat 382) and the front wall 21b is smaller than in the present embodiment. Therefore, when the rainwater W enters the upper space S10 in the fully closed state, it travels along the front beat 382 to the front wall 21b, and easily travels along the front wall 21b. Therefore, when the drainage structure according to the first modification and the interlocking member 380 according to the modification are combined, the rainwater W, which is easily transmitted along the front wall portion 21b by the interlocking member 380, is quickly drained from the first discharge portion 521. Therefore, drainage can be effectively improved.

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

  According to the drainage structure according to the second modification, the rainwater W that enters through the storage opening 21d and travels through the vertical frame 30 and the attachment 40 is guided downward by the first discharge portion 621 and the second discharge portion 622, and is externally guided. Can be discharged to Thereby, since the rainwater W can be discharged (quickly) without passing through the inclined surface 23a of the partition 23, the drainage property can be improved.

  As described above, the position where the first discharge unit 121 is formed is not particularly limited as long as the first discharge unit 121 can discharge the rainwater W in the front space S11. Further, as long as the second drain 122 can discharge the rainwater W in the lower space S20, the position where the second drain 122 is formed is not particularly limited.

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

  Moreover, in the house 1, the fitting provided in the building opening 6 does not necessarily need to be a sweeping sash.

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

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