Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since many of the slats constituting the shutter curtain are made of metal parts, they are directly affected by the external environment, for example, heat or cold air. As a result, the indoor thermal environment becomes close to the external environment and the comfort is impaired. In addition, there is a problem that when the air conditioning equipment is operated to maintain the comfort of the indoor thermal environment, the air conditioning equipment is likely to be burdened. Therefore, an object of the present invention is to provide an opening and closing device capable of improving the indoor thermal environment in order to solve the above problems.

Means for Solving the Problems

[0005] As a configuration of an opening and closing device for solving the above problems, an opening and closing device including an opening and closing body that opens and closes an opening, the opening and closing body is heatThe device includes a sheet-like heat storage member configured to store heat, and when the opening is closed, the heat storage member is provided so as to cover both the front and rear surfaces of the opening / closing body, or the rear surface, and is arranged to shield the space between the front side space and the rear side space partitioned by the opening / closing body. The heat storage member provided on the rear surface of the opening / closing body forms a hollow space between itself and the opening / closing body, In openings where heat exchange is significant, the impact of heat from the outdoors to the indoors can be mitigated, improving the indoor thermal environment. As a result, the load on air conditioning equipment can be reduced, contributing to environmental improvements such as preventing global warming. Furthermore, the heat storage member is provided so as to cover the front surface of the opening / closing body, and to shield the space between the front side space and the rear side space partitioned by the opening / closing body. It's okay if it's placed there. Furthermore, as another configuration for the switching device, a protective member can be provided on top of the heat storage member to protect the heat storage member, thereby preventing damage to the heat storage member. Furthermore, as another configuration for the switching device, by providing a heat storage member to the switching body via an insulating material, the influence of heat from the outdoors to the indoors can be further reduced, and indoor temperature changes can be slowed down. Furthermore, as another component of the opening and closing device, the opening and closing body is equipped with a base plate that contacts the floor surface forming the opening, and the base plate is equipped with a heat storage member that covers part or all of its surface, thereby preventing excessive temperature rise of the base plate due to direct sunlight. This protects electronic components such as sensors installed on the base plate. [Brief explanation of the drawing]

[0007] The present invention will be described in detail below through embodiments of the invention. However, the following embodiments are not intended to limit the invention as defined in the claims, and not all combinations of features described in the embodiments are necessarily essential to the solution of the invention; rather, configurations that can be selectively adopted are included.

[0008] [Embodiment 1] Figure 1 is a plan view of the opening and closing device according to this embodiment, and Figure 2 is a longitudinal cross-sectional view of the shutter curtain and winding mechanism, and a longitudinal cross-sectional view and a partial enlarged view of the slat 31. As shown in FIG. 1, a slat-type shutter device (hereinafter sometimes simply referred to as a shutter device) 10 as an opening / closing device is installed in an opening 12 formed in a structure housing 11. The structure housing 11 is, for example, an outer wall that partitions the inside and outside of a structure such as a house, a building, a warehouse, a factory, etc., or an inner wall that partitions an internal space inside the structure. The opening 12 is formed as a space that is opened in the structure housing 11 and communicates the inside and outside.

[0009] The shutter device 10 roughly includes guide rails 20; 20 that are erected at intervals on both sides in the width direction of the opening 12, a shutter curtain 30 as an opening / closing body that moves along the longitudinal direction of the guide rails 20; 20 and opens or closes the opening 12, a shutter case 14 provided above the opening 12 and the guide rails 20; 20, and a winding mechanism 50 installed in the accommodation space inside the shutter case 14.

[0010] In this specification, the width direction refers to the direction (left-right direction) orthogonal to the opening / closing (up-down) direction of the shutter curtain 30, and the "depth direction" means the thickness (front-back) direction of the shutter curtain 30. Further, the "winding direction" refers to the direction in which the shutter curtain 30 ascends along the guide rail 20 and the opening 12 is opened, and the "pay-out direction" refers to the direction in which the shutter curtain 30 descends along the guide rail 20 and the opening 12 is closed.

[0011] As shown in FIG. 第1, the guide rails 20, 20 are erected in a state where a part of them is embedded in the structure housing 11 so that the longitudinal direction is perpendicular to the structure housing 11. The guide rails 20; 20 are hollow members having an internal structure with a substantially U-shaped cross section. The guide rails 20; 20 are arranged such that the U-shaped openings face each other. Both end portions in the width direction of the shutter curtain 30 described later are inserted into the guide rails 20; 20. Thereby, the end portions in the width direction of the shutter curtain 30 are guided in the opening / closing direction (up-down direction) by the guide rails 20; 20.

[0012] As shown in Figure 2, the shutter curtain 30 is composed of a plurality of slats 31. Each slat 31 is made of a metal such as steel, stainless steel, or aluminum, and is a plate-shaped member that extends along the width direction of the opening 12. Curved curled portions 32;33 are formed at the end in the winding direction (upper end) and the end in the unwinding direction (lower end) of each slat 31, respectively.

[0013] The curl portion 32 curves radially inward of the cylindrical wheel 52 that constitutes the winding mechanism 50 and engages with the curl portion 33 formed on the adjacent slat 31 in the winding direction. The curl portion 33 curves radially inward of the wheel 52 and engages with the curl portion 32 formed on the adjacent slat 31 in the unwinding direction. As a result, adjacent slats 31 are rotatably connected to each other by the engagement of their respective curl portions 32 and 33.

[0014] As shown in the partially enlarged view of Figure 2, each slat 31 is provided with a heat storage member 40 on the front surface 31A and rear surface 31B of the main body 34, which is formed as a flat surface. In the following description, the front surface 31A may be referred to as the outdoor side, the rear surface 31B as the indoor side, etc. The heat storage member 40 can be used by forming a PCM (latent heat storage material, especially a heat storage sheet) material into a sheet shape. For example, the heat storage member 40 is formed in a strip shape with a width dimension about the same as the slat 31 and a vertical dimension shorter than the vertical dimension of the main body 34 between the curled portions 32;33 of the slat 31.

[0015] A PCM (Phase Change Material) is a material that can utilize latent heat, meaning it can store (store) and release (release) heat as energy required when a compound undergoes a phase change from solid to liquid or from liquid to solid at a certain temperature (melting point).

[0016] The heat storage member 40 can be fixed to the slat 31 by means of fixing, such as an adhesive. The adhesive should be one that does not detach from the slat 31 due to heat within the operating temperature range of the heat storage member 40 or over time.

[0017] The operation of the heat storage member 40 will be explained below. [In the summer] When the shutter curtain 30 closes the opening 12, the heat storage member 40 provided on the outdoor side of the shutter curtain 30 is positioned to shield the space between the outdoors and the indoors, absorbing heat from direct sunlight and high outdoor temperatures. Furthermore, the heat storage member 40 provided on the indoor side absorbs and stores heat from the slats 31, thereby mitigating the influence of heat from outdoors to indoors and slowing down indoor temperature changes, such as the rise in room temperature. Furthermore, the heat stored by the heat storage members 40 on the outdoor and indoor sides is gradually released outdoors, either directly or indirectly via the slats 31, as the temperature drops at night, and does not affect the temperature environment indoors. [In winter] When the shutter curtain 30 closes the opening 12, the heat storage member 40 provided on the outdoor side of the shutter curtain 30 is positioned to shield the space between the outdoors and the indoors. As a result, the heat storage member 40 provided on the outdoor side of the shutter curtain 30 directly absorbs heat from direct sunlight, and the heat storage member 40 provided on the indoor side absorbs and stores heat from the slats 31 that have been heated by direct sunlight. This reduces the influence of heat from outdoors to indoors, and thus slows down indoor temperature changes, such as the decrease in room temperature. Furthermore, the heat stored by the heat storage members 40 on the outdoor and indoor sides is gradually released outdoors or indirectly through the slats 31 as the temperature drops at night, thereby mitigating the decrease in indoor temperature due to changes in the outdoor temperature at night. Furthermore, even when the shutter curtain 30 is stored inside the shutter case 14, the heat storage member 40 of the stored shutter curtain 30 can absorb the heat from direct sunlight on the shutter case 14. For example, during the day, the room is warmed by the heat of sunlight passing through the sash glass, etc., and the heat of sunlight is absorbed by the heat storage member 40 of the shutter curtain 30 inside the shutter case 14. At night, by closing the shutter curtain 30, the heat stored in the heat storage member 40 of the shutter curtain 30 can mitigate the heat impact from the opening. In this way, by mitigating the impact of the outdoor thermal environment on indoor spaces, the burden on air conditioning equipment can be reduced.

[0018] The following describes other components of the shutter device 10. As shown in Figure 2, a base plate 35 is engaged with the end of the shutter curtain 30 in the extension direction. The base plate 35 is a rectangular plate in cross-section that extends along the width direction of the shutter curtain 30, and is the part that contacts the floor or ground when the opening 12 is fully closed. The base plate 35 is set to be shorter than, for example, the width dimension of the slat 31 and slightly shorter than the dimension between the guide rails 20;20, so that both ends are not swallowed up by the guide rails 20;20. However, the dimensions of the base plate 35 are not limited to these.

[0019] Next, we will outline the winding mechanism 50 that operates the shutter curtain 30 in the winding or unwinding direction. As shown in Figures 1 and 2, the winding mechanism 50 is installed inside the shutter case 14 and is a mechanism that winds up or unwinds the shutter curtain 30. The winding mechanism 50 comprises left and right brackets 15;15 that constitute part of the shutter case 14, a shaft 51 that is installed between the left and right brackets 15;15, wheels 52;52 that are rotatable in the winding and unwinding directions in synchronization with the rotation of the shaft 51, and a motor (not shown) that rotates the shaft 51 in the winding or unwinding direction.

[0020] The shaft 51 is a support column extending in the width direction of the guide rails 20;20, and is rotatably supported at both ends by retaining means (not shown) provided on brackets 15;15. A driven wheel 53 is provided around the axis of one end of the shaft 51, which is connected to a connecting body 55 such as an endless chain or belt. The driven wheel 53 is connected via the connecting body 55 to a drive wheel provided on the output shaft of a motor (not shown), and the rotational force of the motor is transmitted to the shaft 51 via the drive wheel, the connecting body 55, and the driven wheel 53.

[0021] The wheels 52;52 are cylindrical metal members provided at a predetermined distance from the shaft 51. The wheels 52;52 are fitted onto the shaft 51 through insertion holes (not shown) located in the center of each wheel, and rotate freely around the shaft 51 as the center of rotation. The wheels 52;52 are connected to each other by a plurality of winding members 54. The winding members 54 are support columns extending parallel to the shaft 51, and both ends are fitted into connection holes (not shown) which are opened at equal intervals in the circumferential direction with respect to the insertion holes of the wheels 52;52.

[0022] Furthermore, as shown in Figure 2, the shutter curtain 30 is connected to the wheel 52 by a suspension member 58 fastened to the circumferential surface of the wheel 52. The suspension member 58 is a metal plate with a curved shape corresponding to the curvature of the circumferential surface of the wheel 52. The suspension member 58 is fastened integrally with the wheel 52 by fastening means such as bolts and nuts through fastening holes opened in the circumferential surface of the wheel 52. In addition, a curled connecting portion 58A is formed at the end of the suspension member 58 in the extension direction. The connecting portion 58A engages with the curled portion 32 of the slat 31 located furthest towards the winding direction among the plurality of slats 31 constituting the shutter curtain 30.

[0023] The opening and closing operation of the shutter curtain 30, which has the above configuration, will now be described. As shown in Figure 2(a), when the shutter curtain 30 is in a state where it has opened the opening 12 (fully open state), the motor is driven and controlled by operating the control panel (not shown), and the shaft 51 rotates in the unwinding direction. In response to the rotation of the shaft 51, the wheel 52 rotates, and the shutter curtain 30 stacked on the outer circumference of the wheel 52 is unwinded sequentially. Then, as shown in Figure 2(b), the rotation of the wheel 52 in the unwinding direction continues, and the entire area of ​​the opening 12 is closed by the shutter curtain 30 (fully closed state).

[0024] On the other hand, when the motor is driven in the reverse direction from the state in which the shutter curtain 30 shown in Figure 2(b) closes the opening 12 (fully closed state), and the shaft 51 rotates in the winding direction, the wheel 52 rotates in response to the rotation of the shaft 51, and the shutter curtain 30 is gradually wound up along the outer circumference of the wheel 52, opening the opening 12. Then, as shown in Figure 2(a), when the rotation of the wheel 52 in the winding direction continues and more than the circumference of the wheel 52 of the shutter curtain 30 is wound up, the shutter curtain 30 wound up from the second turn onwards is wound up while being stacked on top of the shutter curtain 30 that was wound up in the first turn, and the entire area of ​​the opening 12 is opened (fully open state). In the above embodiment, the winding mechanism 50 is exemplified as an electrically operated winding mechanism 50 having a motor, but a manual winding mechanism using a biasing means such as a coil spring inserted around the axis of the shaft 51 may also be employed.

[0025] [Embodiment 2] Figures 3 and 4 show other installation configurations of the heat storage member 40 on the slat 31. In the above embodiment, the heat storage member 40 is provided on the front surface 31A and rear surface 31B of the main body portion 34 of the slat 31, but the embodiment is not limited to this. For example, as shown in Figure 3(a), the heat storage member 40 may be provided only on the front surface 31A of the slat 31, or as shown in Figure 3(b), the heat storage member 40 may be provided only on the rear surface 31B of the slat 31.

[0026] [Embodiment 3] Furthermore, the heat storage member 40 may be provided with a hollow section S between it and the slat 31. For example, as shown in Figure 4(a), it may be formed in a U-shape on the rear surface 31B side to connect the extensions that extend from the main body 34 to each curled section 32;33, or, as shown in Figure 4(b), it may be provided linearly to bridge the space between the curled sections 32;33. In this way, by providing a hollow section S between the slat 31 and the heat storage member 40, an air layer is created between the outdoor side and the heat storage member 40, which further slows down changes in room temperature.

[0027] [Embodiment 4] Figure 5 shows an example of the installation of the heat storage member 40 in another form of slat. The slat 31 shown in Figure 5 is formed, for example, by molding a single sheet of material to structurally have a hollow section S. When it has such a hollow structure, for example, as shown in Figure 5(a), the heat storage member 40 may be provided on each of the main body sections 34 on the front 31A side and the rear 31B side within the hollow section S by fixing means such as adhesive, or as shown in Figure 5(b), the heat storage member 40 may be provided only on the main body section 34 on the front 31A side within the hollow section, or as shown in Figure 5(c), the heat storage member 40 may be provided only on the main body section 34 on the rear 31B side within the hollow section. Furthermore, insulation material may be filled between the heat storage member 40 and the slat 31 within the hollow section S. By interposing the hollow section S in this way, the change in room temperature can be made even more gradual.

[0028] In the above embodiment, a shutter curtain 30 composed of multiple slats 31 was described as an example of the opening and closing body of the opening and closing device. However, it may also be an overhead sliding door, or an overhead sliding door or panel curtain made up of multiple flat panels as the configuration of the shutter curtain 30.

[0029] [Embodiment 5] Figures 6 to 8 are longitudinal cross-sectional views of the door component panels of an overhead sliding door. An overhead sliding door is constructed by connecting multiple door component panels 71, which are formed in a rectangular shape with one side elongated along the width direction, similar to a panel curtain. In such a door component panel 71, as shown in Figures 6 and 7, for example, an intermediate frame 76 extending in the width direction is provided between upper and lower frames 72 and 73 that extend in the width direction, on the other side of a panel plate 74, one side of which is formed in a substantially flat shape as a design surface. The door component panel 71 is formed with the upper and lower frames 72 and 73 and the intermediate frame 76 exposed.

[0030] When one side is formed as a decorative surface, the decorative surface faces the outdoors as the front, and the rear side faces the indoors. In this case, the heat storage member 40 can be installed on the rear surface. As shown in Figure 7, if the irregularities on the rear surface are simple, the heat storage member 40 can be attached, for example, to the intermediate frame 76 on the rear surface between the upper and lower frames 72;73.

[0031] Furthermore, as shown in Figure 7, if the heat storage member 40 has folded-back pieces 72A;73A that extend from the upper and lower frames 72;73 so as to face each other, it may be attached by bridging the folded-back pieces 72A;73A.

[0032] Furthermore, as shown in Figure 8(a), if the door configuration panel 71 has a hollow section S in its vertical cross-section, and panel plates 74A and 74B are provided between the upper and lower frames 72 and 73, then the heat storage member 40 should be provided on each of the panel plates 74A and 74B so as to cover the hollow section S side. Also, as shown in Figures 8(b) and (c), the heat storage member 40 may be provided on the hollow section S side of either one of the panel plates 74A or 74B. By interposing the hollow section S in this way, the change in room temperature can be made even more gradual.

[0033] [Embodiment 6] Figure 9 is a cross-sectional view of a door. Furthermore, the opening and closing mechanism is not limited to shutter curtains or panel curtains, but may also be a sliding door or a hinged door. Among hinged and sliding doors, those whose door panels are made solely of metal are, like shutter curtains, directly affected by the external environment, such as warm or cold air. In such cases, as shown in Figures 8 and 9, by providing a heat storage member 40 on the door, it is possible to reduce the impact of the outdoor thermal environment.

[0034] As shown in Figure 9(a), the sheet-like heat storage member 40 may be provided on both the outdoor and indoor sides of the door panel in the interior space of the door door, or it may be provided only on the outdoor side as shown in Figure 9(b), or only on the indoor side as shown in Figure 9(c).

[0035] By attaching a heat storage material to the door panel, it is possible to easily improve the thermal performance without changing the structure of the door, and it can also be applied to existing doors.

[0036] Furthermore, the inside of the door may contain filling materials such as paper cores or insulation. Having such filling materials can further slow down changes in room temperature.

[0037] The door to which the heat storage component 40 is applied does not necessarily have to be made of metal, such as the door panel; it may be a wooden door.

[0038] [Embodiment 7] Figures 10 and 11 show other installation configurations of the heat storage member 40. In the embodiments 1 to 4 described above, the heat storage member 40 was attached to the slats 31 of the shutter, but the invention is not limited to this. For example, as shown in Figures 10 and 11, the heat storage member 40 may be attached to the shutter curtain. The configuration of the shutter device will not be described here, but components identical to those shown in Figures 1 and 2 will be described using the same reference numerals as those shown in Figures 1 and 2.

[0039] As shown in Figure 10, the shutter device 10 generally comprises guide rails 20;20 erected spaced apart from each other on both sides of the width of the opening 12, a shutter curtain 30 as an opening / closing body that moves along the longitudinal direction of the guide rails 20;20 to open or close the opening 12, a shutter case 14 provided above the opening 12 and the guide rails 20;20, a winding mechanism 50 installed in the storage space inside the shutter case 14, and heat storage members 40 provided on the front and rear sides of the shutter curtain 30.

[0040] The heat storage member 40 is formed in a rectangular shape that conforms to the shape of the shutter curtain 30 when viewed from above. For example, one side corresponding to the width dimension of the shutter curtain 30 is fixed to the front and rear sides of the main body portion 34 of the slat 31 located closest to the winding direction using a fixing means such as adhesive, and the other side is aligned with the winding direction of the shutter curtain 30 to attach it to the shutter curtain 30.

[0041] The heat storage member 40 is attached to the shutter curtain 30 as described above, and its length in the width direction and winding direction should be set so that when the shutter curtain 30 closes the opening 12, it covers the entire front and rear sides of the opening 12.

[0042] Furthermore, by attaching the heat storage members 40;40 to the shutter curtain 30, a mechanism for winding up and unwinding the heat storage members 40;40 is eliminated, and the heat storage members 40;40 can be automatically positioned and retracted as the shutter curtain 30 opens and closes.

[0043] When fixing the heat storage members 40 to the slats 31 using an adhesive, it is preferable to use a durable adhesive to prevent the heat storage members 40 from falling off due to heat or aging before reaching their operating temperature.

[0044] The operation of the shutter device with the above configuration will now be described. As shown in Figure 11(a), when the shutter curtain 30 is in a state where it has opened the opening 12 (fully open state), the motor is driven and controlled by operating the control panel (not shown), and the shaft 51 rotates in the unwinding direction. In response to the rotation of the shaft 51, the wheel 52 rotates, and the stacked shutter curtain 30 is sequentially unwinded along with the heat storage members 40;40 on the outer surface of the wheel 52. Then, as shown in Figure 11(b), the rotation of the wheel 52 in the unwinding direction continues, the entire area of ​​the opening 12 is closed by the shutter curtain 30 (fully closed state), and the heat storage members 40;40 are positioned on the front and rear sides of the shutter curtain 30.

[0045] Furthermore, when the motor is driven in the reverse direction from the state in which the shutter curtain 30 shown in Figure 11(b) closes the opening 12 (fully closed state), and the shaft 51 rotates in the winding direction, the wheel 52 rotates in response to the rotation of the shaft 51, and the shutter curtain 30 is gradually wound up along the outer surface of the wheel 52 together with the heat storage members 40;40, opening the opening 12. Then, as shown in Figure 11(a), when the rotation of the wheel 52 in the winding direction continues and more than the circumference of the wheel 52 of the shutter curtain 30 is wound up, the shutter curtain 30 wound up from the second turn onwards is wound up while being stacked together with the heat storage members 40;40 on the shutter curtain 30 that was wound up together with the heat storage members 40;40 in the first turn, and the entire area of ​​the opening 12 is opened (fully open state).

[0046] Even if the heat storage member 40 is provided on the shutter device in this manner, the effects described in each of the embodiments above can be obtained. Note that the heat storage member 40, which is attached to the shutter curtain 30, is not limited to both the front and rear sides, but may be located on either the front or rear side.

[0047] [Embodiment 8] Figure 12 shows another installation configuration of the heat storage member 40. In Embodiment 7, the heat storage member 40 was described as being installed in direct contact with the shutter curtain 30, but as shown in Figure 12, a protective sheet 42 may be interposed between the shutter curtain 30 and the heat storage member 40.

[0048] The protective sheet 42 is provided overlapping the rear side of the shutter curtain 30 and is a member that prevents the slats 31 from directly contacting the heat storage members 40 on the front and rear sides when the shutter curtain 30 is rolled up. The protective sheet 42 may be made of a sheet-like material such as a highly breathable mesh or film. The protective sheet 42 is formed in a rectangular shape of about the same size as the heat storage member 40 in order to cover the entire surface of the heat storage member 40, and is attached to the main body portion 34 of the slat 31 to which the heat storage member 40 is fixed, overlapping the heat storage member 40 with a fixing means such as adhesive.

[0049] Furthermore, a highly breathable mesh structure refers to a mesh size that does not hinder the exchange of heat to and from the heat storage member 40. It goes without saying that the protective sheet 42 has the strength to prevent the slats 31 from contacting the heat storage member 40 when the shutter curtain 30 is rolled up, and the flexibility to accommodate deformation during rolling.

[0050] Furthermore, although the entire surface of the rear heat storage member 40 is covered with a single protective sheet 42, the invention is not limited to this. For example, the protective sheet 42 may be in the shape of a strip of a predetermined width, and this strip-shaped protective sheet 42 may be provided at predetermined intervals in the width direction of the shutter curtain 30, extending from one end to the other in the opening and closing direction of the shutter curtain 30.

[0051] In this way, by overlapping the protective sheet 42 with the rear heat storage member 40, as shown in Figure 12(a), it can be interposed between the rolled-up front and rear heat storage members 40 together with the shutter curtain 30, thereby preventing pre-damage to the heat storage member 40.

[0052] [Embodiment 9] Figure 13 shows another installation configuration of the heat storage member 40. In Embodiment 8, the heat storage member 40 was described as being provided on both the front and rear sides of the shutter curtain 30, but as shown in Figure 13, an insulating material 44 may be provided instead of the heat storage member 40 on the front side.

[0053] The thermal insulation material 44 is, for example, a sheet-like member that suppresses the transfer of heat from one side to the other side. It is preferable that the insulation material 44 is made of a material and has a thickness that allows it to be flexible enough to follow the deformation of the shutter curtain 30 when it is rolled up or unrolled.

[0054] The thermal insulation material 44 is formed in a rectangular shape to cover the entire area of ​​the shutter curtain 30 and is attached to the main body 34 of the slat 31 to which the heat storage member 40 is fixed by a fixing means such as an adhesive.

[0055] In this way, by interposing the insulating material 44 between the outdoor side and the heat storage member 40, changes in room temperature can be made more gradual, and the rise in temperature in summer and the fall in winter can be suppressed.

[0056] Although the heat storage member 40 is attached to the shutter curtain 30, it may also be attached to the suspension member 58, which together with the shutter curtain 30 constitutes the winding mechanism 50. Furthermore, although the heat storage member 40 is configured to be wound up and unwound together with the shutter curtain 30 using the winding mechanism 50 of the shutter curtain 30, the configuration is not limited to this. The heat storage member 40 and the protective sheet 42 and insulation material 44 may also be wound up and unwound separately from the shutter curtain 30 using a different winding mechanism.

[0057] [Embodiment 10] Figure 14 is a schematic diagram showing other installation configurations of the heat storage member 40. As shown in Figure 14, the heat storage member 40 can be configured, for example, as a heat storage unit 80 including a winding device. In the following description, the heat storage member 40 alone, the heat storage member 40 combined with a protective sheet 42, the heat storage member 40 combined with a protective sheet 42 and an insulating material 44, etc., are collectively referred to as heat storage body A. The heat storage unit 80 can consist of a heat storage body A, a winding shaft 82 for winding up the heat storage body A, a bearing (not shown) that rotatably supports the winding shaft 82, a winding spring (not shown) that applies a biasing force to the winding shaft 82 in the direction that the winding shaft 82 winds up the heat storage body A, and a case 84 that houses these components.

[0058] The heat storage body A consists of only the heat storage member 40, or a protective sheet 42 superimposed to cover the entire area of ​​one or both sides of the heat storage member 40. For example, the heat storage body A is formed in a rectangular shape that can cover the entire area of ​​the opening 12 where the shutter device 10 is provided, and can be housed in the case 84 while wound on the winding shaft 82 by the biasing force of the winding spring.

[0059] As shown in Figure 14, the heat storage units 80 are arranged, for example, on the front and rear sides of the shutter curtain 30 within the shutter case 14. Each of the front and rear heat storage units 80 is fixed within the shutter case 14 such that the winding shaft 82 of the heat storage body A is parallel to the axis of the shaft 51 of the winding mechanism 50 of the shutter curtain 30. The heat storage body A, when wound on the winding shaft 82, is pulled out from each of the front and rear heat storage units 80. This pulled-out side (hereinafter referred to as the pull-out end) is fixed to the front and rear sides of the base plate 35 by fixing means not shown, thereby being incorporated as part of the shutter device 10.

[0060] The operation when configured as a heat storage unit 80 will be described below. As shown in Figure 4(b), when closing the opening with the shutter curtain 30 from an open state to as shown in Figure 14(a), extending the shutter curtain 30 pulls out the heat storage body A from the winding shaft 82, allowing the heat storage body A, which has a heat storage function, to be placed on the front and rear sides of the shutter curtain 30. Furthermore, as shown in Figure 14(a), when the shutter curtain 30 opens the opening from a state where it is closed to a state where it is open

[0061] [Embodiment 11] Figure 15 is a schematic diagram showing other installation configurations of the heat storage member 40. It should be noted that the heat storage unit 80 does not necessarily have to be housed inside the shutter case 14; for example, as shown in Figure 15, it may be attached to the bottom surface of the shutter case 14 or the like.

[0062] [Embodiment 12] Figure 16 is a schematic diagram showing other installation configurations of the heat storage member 40. In the case where the heat storage body A is provided on the front and rear sides of the shutter curtain 30, two heat storage units 80 are provided on the front and rear sides of the shutter curtain 30. However, as shown in Figure 16, for example, the heat storage body A can also be provided on the front and rear sides of the shutter curtain 30 using a single heat storage unit 80. In this case, a roller 86 extending along the width direction of the seat plate 35 is rotatably provided on the underside of the seat plate 35, and the heat storage body A drawn out from the heat storage unit 80 is passed through the roller 86, and the end of the drawn-out heat storage body A is attached to the underside of the shutter case 14. Even with this configuration, the heat storage body A can be rolled up and pulled out in conjunction with the winding and unwinding of the shutter curtain 30 without sagging.

[0063] [Embodiment 13] Figure 17 is a schematic diagram showing another installation configuration of the heat storage member 40. As shown in Figure 17(a), the base plate 35 is made into a hollow box shape, and the heat storage unit 80 is constructed by providing a heat storage body A, a winding shaft 82 for winding up the heat storage body A, a bearing (not shown) that rotatably supports the winding shaft 82, and a winding spring (not shown) that applies a biasing force to the winding shaft 82 in the direction that the winding shaft 82 winds up the heat storage body A. In other words, it can be said that the aforementioned heat storage unit 80 is attached to the lower end of the slat 31 instead of the plate-shaped base plate 35. In this case, the unwinding end of the heat storage body A can be fixed to the lower surface of the shutter case 14 or the like by fixing means (not shown). Note that in Figure 17(a), the heat storage body A is shown on the rear side of the shutter curtain 30 as an example, but it may also be on the front side.

[0064] Furthermore, as shown in Figure 17(b), by housing two heat storage units 80 inside the hollow box-shaped base plate 35, heat storage bodies A can be provided on the front and rear sides of the shutter curtain 30. As shown in Figures 17(a) and (b), even with the heat storage unit 80 configured, the heat storage body A can be wound up and unwound in conjunction with the winding and unwinding of the shutter curtain 30 without sagging.

[0065] Figure 18 shows another form of the heat storage member 40. In the above-described embodiment, the heat storage member 40 was made in the form of a single sheet and configured to be wound up and unwound on a winding shaft 82, but it is not limited to this, and may be formed to be foldable by bellows folding as shown in Figure 18.

[0066] As shown in Figure 18, the heat storage member 40 may be formed by bellows folding so that it can expand and contract in the direction of the folds. In this case, for example, the shape of the base plate 35 can be made into a box shape with an opening at the top, and the heat storage member 40 folded by bellows folding can be housed inside. The bottommost folded piece can be fixed to the base plate 35 by adhesive or the like, and the topmost folded piece can be fixed to the bottom surface of the shutter case 14 by adhesive or the like.

[0067] In an accordion fold, the bottom and top folds separate, causing expansion in the folding direction, and the bottom and top folds move closer together, causing contraction in the folding direction. Therefore, as shown in Figure 18(b), when the shutter curtain 30 is rolled up and then unrolled from the state where the opening 12 is open, the base plate 35 gradually separates from the shutter case 14. The heat storage member 40 unfolds and expands in conjunction with this separation. Then, as shown in Figure 18(a), when the shutter curtain 30 completely closes the opening 12, the heat storage member 40 covers the entire front and rear sides of the shutter curtain 30.

[0068] Furthermore, as shown in Figure 18(a), by extending the shutter curtain 30 and then winding it up from the closed position of the opening 12, the base plate 35 gradually approaches the shutter case 14. In conjunction with this approach, the heat storage member 40 folds up and gradually contracts. Then, as shown in Figure 18(b), when the shutter curtain 30 is wound up and the opening 12 is completely open, the heat storage member 40 is in its most folded state and is housed in the base plate 35.

[0069] In this way, by making the heat storage member 40 foldable by bellows folding, a winding mechanism for winding up the heat storage member 40 can be eliminated, and the heat storage member 40 can be easily attached to the shutter device 10. It should be noted that the form of the heat storage member 40 that provides expansion and contraction functionality is not limited to bellows folding; for example, the heat storage member 40 may be formed to have a structure that allows expansion and contraction, such as a pantograph or honeycomb.

[0070] In the above embodiment, the shutter device 10 was described using examples such as a slat type or a panel type, but a sheet curtain made of a non-combustible resin or the like may also be used. Sheet curtains often have thin fabric and lack adequate insulation at the opening, making them highly susceptible to the effects of the external environment (heat and cold air). As a result, similar to metal shutter curtains, the indoor thermal environment becomes close to the external environment, making it difficult to achieve comfort. However, even with such sheet curtains, for example, by providing a heat storage member 40 or heat storage body A to cover its surface, changes in room temperature during summer and winter can be mitigated.

[0071] Furthermore, the heat storage element A of the heat storage unit 80 described in Embodiment 10, etc., may be used as a sheet curtain as an opening and closing element in a (sheet) shutter device, or the heat storage unit 80 may be configured as a roll curtain.

[0072] Furthermore, the heat storage member 40 may be provided on part or all of the surface of a seat plate 35 that is provided to make contact with the floor or ground when the opening 12 is fully closed in the aforementioned slat-type, panel-type, or other shutter device 10, or in an opening / closing body such as a sheet curtain. For example, some shutter devices 10 have an opening / closing mechanism whose opening and closing is controlled by a motor. In such a shutter device 10, electronic components such as a sensor for detecting when the base plate 35 touches the floor surface when the opening / closing mechanism closes the opening 12, and a sensor for detecting pinching between the base plate 35 and the floor surface are provided on the base plate 35. Such sensors are sensitive to heat, which can cause errors in the aforementioned detection or lead to malfunctions. Therefore, a heat storage member 40 is provided on the base plate 35 so as to cover part or all of its surface, and the heat storage member 40 absorbs the heat from sunlight, thereby preventing excessive temperature rise of the base plate 35 due to direct sunlight, protecting electronic components such as sensors, and preventing sensor malfunctions caused by sunlight.
