[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-144323 Summary of the Invention [Problem to be solved by the invention]

[0005] In the technology of the above-mentioned Patent Document 1, a winch mechanism and two rollers connected to a clutch-equipped motor are used to move the sheet for opening and closing the roof, and the structure of the roof opening and closing mechanism cannot be said to be sufficiently simplified. In addition, the sheet removed from the roof may be bulky, so the operation of opening the roof may be time-consuming.

[0006] The technology disclosed herein has an objective of providing a building whose roof can be easily opened and closed with a simpler configuration. [Means for solving the problem]

[0007] The technology of the present disclosure can be realized in the following forms.

[0008] [First embodiment] One embodiment of the technology disclosed herein is provided as a building. The building of the first embodiment includes a frame portion that constitutes the framework of a roof portion, a sheet portion that is stretched across the frame portion in the length direction so as to cover the roof portion, and an opening / closing mechanism that is connected to an end of the sheet portion in the length direction and has a rotating shaft portion that is configured to be able to wind up the sheet portion in a roll in the length direction by rotation, and that opens the roof by winding up the sheet portion on the rotating shaft portion. According to the building of the first embodiment, the roof can be easily opened by a simple configuration in which the rotating shaft is rotated to wind up the sheet part in a roll. In addition, after the roof is opened, the sheet part is wound up in a roll on the rotating shaft, so that the sheet part removed from the roof can be prevented from becoming bulky.

[0009] [Second Form] In the building described in the first form above, the rotating shaft portion is a first rotating shaft portion connected to a first end portion, which is the end of the sheet portion, and a plurality of string-like bodies arranged in parallel to each other at intervals in the width direction of the sheet portion are connected to a second end portion opposite the first end portion of the sheet portion, and the opening / closing mechanism further has a second rotating shaft portion connected to the second end portion via the plurality of string-like bodies and configured to be able to wind up each of the plurality of string-like bodies in parallel by rotation, and the opening / closing mechanism may open the roof by winding up the sheet portion from the second rotating shaft portion to the first rotating shaft portion and causing the plurality of string-like bodies unwound from the second rotating shaft portion to be stretched over the frame portion, and close the roof by winding up the plurality of string-like bodies around the second rotating shaft portion and stretching the sheet portion unwound from the first rotating shaft portion over the frame portion. According to the second embodiment of the building, the roof can be easily opened by winding the sheet part around the first rotating shaft part, and the roof can be easily closed by winding the multiple string-like bodies around the second rotating shaft part. Therefore, the roof can be easily opened and closed by the opening and closing mechanism with a simple configuration using two rotating shaft members.

[0010] [Third Form] In the building described in the second form above, the second rotating shaft portion may be provided with a plurality of pairs of guide plates arranged to sandwich each of the plurality of string-like bodies and guiding the winding of the plurality of string-like bodies. According to the building of the third embodiment, the plurality of pairs of guide plates can make it easier to wind up the plurality of string-like bodies and the sheet portion around the second rotating shaft, thereby making it easier to open and close the roof.

[0011] [Fourth Configuration] In the building described in the third configuration, each end of the pair of guide plates may be provided with an inclined surface that slopes downward toward the area where the string-like body is wound up. According to the building of the fourth embodiment, the string-like body can be wound up around the second rotating shaft more smoothly, which makes the work of closing the roof even easier.

[0012] [Fifth Form] In a building described in any of the first, second, third and fourth forms above, the frame portion includes a pair of rail portions arranged along both side end portions in the width direction of the arrangement area of ​​the sheet portion when it is stretched over the frame portion, and each of the both side end portions of the sheet portion may be provided with a guided member that moves along the pair of rail portions when the sheet portion is wound up around the rotating shaft portion. According to the fifth embodiment of the building, when the sheet part is stretched over the frame part, the guided members provided on the side ends of the sheet part move along the rail parts, so that the sheet part is prevented from being biased in the width direction. This makes it even easier to open and close the roof.

[0013] The technology disclosed herein can be realized in forms other than buildings, for example, in the form of a roof opening and closing mechanism or method, a winding mechanism or method for the sheet portion that constitutes the roof, a rotating shaft portion or sheet portion that constitutes the roof opening and closing mechanism, etc. [Brief description of the drawings]

[0015] 1. Implementation: 1 and 2 are schematic perspective views showing a building 10 of this embodiment. Fig. 1 shows a state in which a roof portion 12 of the building 10 is closed, and Fig. 2 shows a state in which the roof portion 12 is open.

[0016] For the sake of convenience in the description herein, the "X direction," "Y direction," and "Z direction" are defined as directions related to the building 10 as follows. The X direction, Y direction, and Z direction are perpendicular to each other. The X direction is the lateral direction of the building 10, and corresponds to the left-right direction when facing the front of the building 10. The Y direction is the depth direction of the building 10, and corresponds to the direction from the front to the back of the building 10. The Z direction is the height direction of the building 10, and is a direction perpendicular to the foundation ground surface of the building 10.

[0017] The building 10 of this embodiment comprises a side wall portion 11 that surrounds the internal space of the building 10, a roof portion 12 that covers the upper part of the internal space of the building 10, and an opening / closing mechanism 20 for opening and closing the roof portion 12. The side wall portion 11 is composed of a number of pillars and a wall portion stretched between the pillars. The side wall portion 11 is provided with an entrance, windows, and the like for the building 10. The roof portion 12 is supported from below by the side wall portion 11.

[0018] In the building 10, the roof portion 12 is configured to be openable and closable. The roof portion 12 includes a frame portion 15 that forms a framework, and a sheet portion 18 that is stretched across the frame portion 15.

[0019] In the building 10, when the roof section 12 is closed, it means that the sheet section 18 is stretched over the frame section 15 so as to cover the entire upper part of the interior space of the building 10, as shown in Fig. 1. When the roof section 12 is open, it means that the frame section 15 is exposed to the outside, and the interior space of the building 10 communicates with the outside of the building 10 through the gaps in the frame section 15, as shown in Fig. 2.

[0020] 2, the frame section 15 of the roof section 12 is formed by assembling a plurality of steel frame members in a lattice pattern. The roof section 12 of this embodiment is configured in a substantially semi-cylindrical shape with the highest point in the center in the X direction, and the frame section 15 has, as the steel frame members, a plurality of curved frames 15a and a plurality of linear frames 15b.

[0021] The curved frames 15a are each curved in an arc shape and are arranged at a predetermined interval in the Y direction. The straight frames 15b are arranged at a predetermined interval in the X direction and are connected to the curved frames 15a at their intersections. With the roof 12 having such an upwardly convex curved shape, the sheet 18 can be easily stretched over the frame 15.

[0022] In this embodiment, the frame portion 15 further has a pair of rail portions 35. The pair of rail portions 35 will be described later.

[0023] The sheet portion 18 is made of, for example, a fluorine-treated polyester fabric. The sheet portion 18 is not limited to a polyester fabric and may be made of various other fabrics. The sheet portion 18 may be made of, for example, a nylon fabric, a cotton fabric, or a polycotton fabric. It is preferable that the sheet portion 18 is made of a flame-retardant fabric.

[0024] The opening and closing mechanism 20 for the roof section 12 of the building 10 will be described with reference to Figures 3 to 8 as appropriate in addition to Figures 1 and 2. Figure 3 is a schematic diagram of the frame section 15 of the roof section 12 and the two rotating shaft sections 21, 22 of the opening and closing mechanism 20 as viewed from above. For convenience, the sheet section 18, side wall section 11, and support section 23 are not shown in Figure 3. Figure 4 is a schematic plan view showing the sheet section 18 that constitutes the roof section 12.

[0025] As shown in Fig. 3, the opening / closing mechanism 20 includes a first rotating shaft portion 21 and a second rotating shaft portion 22. The first rotating shaft portion 21 and the second rotating shaft portion 22 are disposed along the Y direction on both sides in the X direction of the frame portion 15. As shown in Fig. 4, the sheet portion 18 is installed on the roof portion 12 such that its length direction is the X direction and its width direction is the Y direction.

[0026] 1 and 2, the first rotating shaft portion 21 and the second rotating shaft portion 22 are supported by a support portion 23 below the roof portion 12. In the example of FIG. 1 and FIG. 2, the support portion 23 is installed on the ground at a position separated from the side wall portion 11. In other embodiments, the support portion 23 may be connected to the side wall portion 11 and supported by the side wall portion 11.

[0027] As shown in Fig. 3, a handle portion 24 is connected to each end of the first rotating shaft portion 21 and the second rotating shaft portion 22. The handle portion 24 may be provided on both ends of each of the rotating shaft portions 21, 22 as shown in the figure, or may be provided only on one end. As shown in Figs. 1 and 2, the first rotating shaft portion 21 and the second rotating shaft portion 22 are held by a support portion 23 in a state in which they can rotate by rotating the handle portion 24. The support portion 23 may hold each of the rotating shaft portions 21, 22 via a bearing, for example.

[0028] 3 and 4. A first end 19a in the length direction of the sheet unit 18 is connected across the entire width direction to a side surface of the first rotating shaft unit 21. This allows the sheet unit 18 to be wound up in a roll around the side surface of the first rotating shaft unit 21 by rotating the first rotating shaft unit 21 around its central axis.

[0029] As shown in Fig. 4, a plurality of string-like bodies 30 are connected to a second end portion 19b of the sheet portion 18 in the longitudinal direction so as to extend from the second end portion 19b in the longitudinal direction of the sheet portion 18. The string-like bodies 30 can be formed, for example, of a flat belt, and can be made of a long and narrow fabric formed by weaving polyester in multiple layers. The string-like bodies 30 are arranged in parallel to each other at a predetermined interval across the width direction of the sheet portion 18.

[0030] 3 and 4. The second end 19b of the sheet portion 18 is connected to the side surface of the second rotating shaft portion 22 via the above-mentioned multiple string-like bodies 30. In this way, by rotating the second rotating shaft portion 22 around its central axis, the string-like bodies 30 can be wound up in parallel around the side surface of the second rotating shaft portion 22, and the sheet portion 18 can be pulled toward the second rotating shaft portion 22.

[0031] Please refer to Figures 3 and 5. Figure 5 is a schematic perspective view showing an example of a pair of guide plates 32 provided on the second rotating shaft portion 22. Figure 5 illustrates a state in which one string-like body 30 is wound between the pair of guide plates 32.

[0032] As shown in Fig. 3, the second rotating shaft portion 22 is provided with a pair of guide plates 32 for each of the string-like bodies 30. As shown in Fig. 3 and Fig. 5, each of the pair of guide plates 32 is formed of a substantially disk-shaped member through the center of which the second rotating shaft portion 22 penetrates. Each of the pair of guide plates 32 is disposed so as to sandwich each of the string-like bodies 30 in the axial direction of the second rotating shaft portion 22 so as to guide the winding of each of the string-like bodies 30.

[0033] By providing the pair of guide plates 32 on the second rotating shaft portion 22, the positions at which the string-like bodies 30 are wound on the second rotating shaft portion 22 are prevented from varying. This facilitates the winding of the string-like bodies 30 by the second rotating shaft portion 22. After each string-like body 30 is wound on the second rotating shaft portion 22, when the sheet portion 18 is subsequently wound into a roll on the second rotating shaft portion 22, the sheet portion 18 is stacked in a roll while being supported by the radially outer end faces of the guide plates 32. This facilitates the winding of the sheet portion 18 on the second rotating shaft portion 22.

[0034] Please refer to Fig. 5. In this embodiment, an inclined surface 33 is provided at the radially outer end of each of the pair of guide plates 32, which is inclined downward toward the area where the string-like body 30 is wound. The inclined surfaces 33 of the pair of guide plates 32 face each other in the axial direction of the second rotating shaft portion 22. By providing this inclined surface 33, the string-like body 30 is guided to the area between the corresponding pair of guide plates 32. This makes it even easier to wind up the string-like body 30 by the second rotating shaft portion 22.

[0035] Please refer to Fig. 3. As described above, the frame portion 15 has a pair of rail portions 35. The pair of rail portions 35 are arranged along both side ends in the width direction of the arrangement area of ​​the sheet portion 18 when the sheet portion 18 is stretched across the frame portion 15. In this embodiment, as shown in Fig. 2, each rail portion 35 is curved similarly to the curved frame 15a, and is arranged at both ends of the frame portion 15 in the Y direction.

[0036] 3, a rail groove 36 is formed in the X direction on the surface of each rail portion 35 facing the sheet portion 18. The rail groove 36 has a substantially rectangular cross section as shown in FIG. 6, which will be referred to later.

[0037] Please refer to Fig. 4. Guided members 38 are provided at portions of the sheet portion 18 facing the rail portions 35. In Fig. 4, the arrangement area of ​​the guided members 38 on the sheet portion 18 is shown by a dashed line. The guided members 38 are provided on both side ends of the second end portion 19b in the X direction. The guided members 38 are configured to be movable along the corresponding rail portions 35.

[0038] Please refer to Fig. 6. Fig. 6 is a schematic perspective view showing an example of a guided member 38. Fig. 6 illustrates a state in which the guided member 38 is fitted into the rail groove 36 of the rail portion 35. For convenience, Fig. 6 illustrates the seat portion 18 by a dashed line.

[0039] The guided member 38 is made of a resin material such as Duracon (registered trademark), i.e., polyacetal copolymer (POM; polyacetal, polyethylene). In this embodiment, the guided member 38 has a configuration in which a rectangular upper portion 38a having a smaller width is laminated on a rectangular lower portion 38b having a larger width. In the guided member 38, the lower portion 38b has a smaller volume than the upper portion 38a, and the center of gravity of the guided member 38 is located at the lower portion 38b. The lower portion 38b of the guided member 38 is movable so as to slide along the rail groove 36 while being fitted in the rail groove 36. The upper surface of the upper portion 38a is fixed to the sheet portion 18.

[0040] When the sheet portion 18 is wound up toward the first rotating shaft portion 21 or the second rotating shaft portion 22, the guided member 38 moves along the rail portion 35. Therefore, when the sheet portion 18 is wound up, the side end portion of the sheet portion 18 is prevented from being biased in the width direction. This makes it possible to more smoothly wind up the sheet portion 18 by the first rotating shaft portion 21 or the second rotating shaft portion 22 and stretch the sheet portion 18 over the roof portion 12. In this embodiment, as described above, the width of the upper portion 38a is narrow, and the width of the lower portion 38b that fits into the rail groove 36 of the rail portion 35 is wide. Therefore, the posture of the guided member 38 that moves along the rail groove 36 can be more stabilized while suppressing an increase in the weight of the guided member 38. Furthermore, as described above, in this embodiment, the center of gravity of the guided member 38 is located in the lower portion 38b, so that the posture of the guided member 38 as it moves along the rail groove 36 is further stabilized, and falling off of the guided member 38 from the rail groove 36 is suppressed.

[0041] The opening and closing operation of roof portion 12 of building 10 will be described with reference to Figures 7 and 8. Figures 7 and 8 are schematic plan views of roof portion 12 of building 10 as viewed from above. Figure 7 shows roof portion 12 in a closed state, and Figure 8 shows roof portion 12 in the process of being opened.

[0042] When opening the closed roof portion 12, the first rotating shaft portion 21 is rotated as shown by the solid arrow in Fig. 7, and the sheet portion 18 is wound up in a roll around the first rotating shaft portion 21. Then, as shown by the solid arrow in Fig. 8, the sheet portion 18 is wound up around the first rotating shaft portion 21, and as shown in Figs. 2 and 8, the multiple string-like bodies 30 unwound from the second rotating shaft portion 22 are stretched across the frame portion 15, and the roof portion 12 is opened.

[0043] When closing the roof portion 12 that is in an open state, the second rotating shaft portion 22 is rotated to wind up the multiple string-like bodies 30 onto the second rotating shaft portion 22, as shown by the dashed-dotted arrow in Fig. 8. As a result, the sheet portion 18 wound up on the first rotating shaft portion 21 is pulled in its length direction onto the frame portion 15, as shown by the dashed-dotted arrow in Fig. 7, and the sheet portion 18 is stretched across to cover the entire top of the frame portion 15. Then, as shown in Fig. 1, the roof portion 12 is closed.

[0044] As described above, according to the building 10 of this embodiment, the roof portion 12 can be easily opened by the simple configuration of rotating the first rotating shaft portion 21 and winding the sheet portion 18 into a roll. Furthermore, after the roof portion 12 is opened, the sheet portion 18 is wound into a roll on the first rotating shaft portion 21, so that the sheet portion 18 removed from the roof portion 12 is prevented from becoming bulky.

[0045] Furthermore, in the building 10 of this embodiment, the roof portion 12 can be closed by winding up the multiple string-like bodies 30 connected to the sheet portion 18 onto the second rotating shaft portion 22 and unwinding the sheet portion 18 wound up on the first rotating shaft portion 21 onto the roof portion 12. Thus, the sheet portion 18 is wound up in a roll, and the roof portion 12 can be repeatedly opened and closed.

[0046] In this way, according to the building 10 of this embodiment, the roof can be opened and closed easily with a simpler configuration.
