Movable roof

Description: TECHNICAL FIELD [Detailed description of the invention]

"Industrial application field" The present invention relates to a retractable roof that is suitable when the object to which the roof should be erected is a large-scale space such as a stadium. "Conventional technology" The retractable roof can meet the conflicting demands of being able to obtain a feeling of openness outdoors, sunlight, fresh air, etc., and also eliminate the harmful effects of rain, and various configurations have already been provided or proposed. Has been done. For example, the roof is flattened into a foldable structure, and the roof is opened and closed by folding or expanding it, or as shown in Fig. 5, the roof is divided into a fixed roof part 1 and a moving roof part. There is a configuration in which the moving roof portion 2 is pulled over (inside) the fixed roof portion 1 to open a part of the upper part of the roof erection target site S. Further, as shown in FIGS. 6 and 7, at least two roof units 3 formed in a fan shape are swiveled around the support column 4 which is the center of the fan shape as a fulcrum to move the roof to the roof erection target S. The roof unit 3 shares the same turning center, and the roof unit 3 is located in the vicinity of the fan-shaped arc and the vicinity of the turning center, respectively. A first support leg 5 and a second support leg 6 for supporting the roof unit 3 are provided, and the first support leg 5 and the second support leg 6 move along tracks 7 and 8, respectively. A configuration provided with a slide mechanism is also known. "Problems to be solved by the invention" By the way, in such a conventional retractable roof, although the initial purpose has been achieved in that the roof can be opened and closed, each has the following drawbacks. That is, in the former foldable type, the operating mechanism is complicated and the form is limited to a plate-like flat type from the structural point of view, and the design of the entire building is lacking. Further, in the case of FIG. 5, since the fixed roof portion 1 supports the moving roof portion 2, not only the fixed roof portion 1 needs to be structurally strengthened, but also the moving roof portion 2 cantilever. Since it is a form, it is necessary to strengthen the structure and the cost is high. On the other hand, the retractable roofs shown in FIGS. 6 and 7 have the advantage that they can be erected and moved out to the roof erection target S arbitrarily and easily, but the support column 4 exists at the center of rotation of the roof unit 3. As a result, it becomes a big restriction in designing the roof erection target S on which this roof is erected, and in the model in which the roof unit 3 is supported by the rotation center in this way, stress concentration on the rotation center axis and Due to problems such as stress concentration in the central part of the roof unit 3 itself, it is difficult to make an economic design from the viewpoint of its structure and weight reduction, and it is difficult to open and close the roof 100%. There are various problems to be improved, such as the fact that the side wall portion must surround the roof erection target S and move out at the same time as the roof unit 3, which increases the cost. Therefore, in the present invention, a large-scale space above a stadium or the like can be opened and closed 100% by a simple method in which a plurality of moving roofs are integrally turned horizontally and traveled in a straight line. By adopting an arch shape that supports both ends of the moving roof, the weight can be reduced, the cost can be reduced, etc. as an economical design compared to the cantilever beam and the arch shape of the swivel center axis support type. Also seeks to provide a retractable roof that is extremely novel. "Means to solve problems" The present invention is a retractable roof in which a dome-shaped roof is openable and closable by a plurality of arch-shaped moving roofs that overlap vertically, and a pair of parallel roofs that are located on both sides of a roof erection object and extend in parallel. A support portion and a circular support portion located around the roof erection target and inscribed in the parallel support portion are provided, and the moving roof is horizontally movable by being supported at both ends by a track provided on the parallel support portion. Two or more swivel roofs that are stored in a layered manner inside the main roof body and each of which is supported at both ends by a track provided on the circular support portion so that it can stand on its own and can swivel. It is characterized in that it has a structure consisting of and. "Action" Since the dome-shaped roof is composed of a main roof body that can travel horizontally and linearly and a plurality of swivel roofs that are stored inside the main roof body and can be swiveled, the roof is closed. To make it, the swivel roofs swivel to their fixed positions to completely close the space above the roof erection target, and to open them, each swivel roof is stored in layers inside the main roof body. All the roofs move horizontally to the side as one, and the upper space to be erected on the roof is fully opened. The main roof body and the swivel roof that make up the moving roof are both self-supporting arch-shaped ones, and the swivel roof is self-supporting and swivel without being supported by others. "Example" Hereinafter, examples of the present invention will be described with reference to the accompanying drawings. FIGS. 1 to 4 show an example in which the retractable roof according to the present invention is applied to a large-scale space such as a baseball stadium. In these figures, reference numeral 10 is a structure supporting the roof, and reference numeral 20 is a moving roof forming a so-called dome-shaped roof with the roof closed. The structure 10 that supports the moving roof 20 includes a pair of parallel support portions 11 and 11 that are located opposite to each other on both sides of the stadium S having a substantially circular plane to be erected and extend in parallel, and the stadium S. It is configured to have circular support portions 12 and 12 located around the above and inscribed in the parallel support portions 11 and 11. Support surfaces 11a and 12a inclined inward from each other are provided on the upper portions of the parallel support portions 11 and 11 and the circular support portions 12 and 12, respectively, and these support surfaces 11a and 12a are shown in FIG. As described above, two pairs of straight orbits T1 and T1 that guide the moving roof 20 horizontally and linearly along the parallel support portions 11 and 11, and three swivel roofs described later that form a part of the moving roof 20. A pair of arc tracks R1, R2, and R3 are laid along each circumference so that they can turn horizontally. As shown in FIG. 1, the moving roof 20 has a butterfly shape centered on the center of the circle in a plan view, and has an arch-shaped cross section as shown in FIG. It is made up of the body. That is, the moving roof 20 has a single main roof body 21 which is supported at both ends by the straight tracks T1 and T1 provided on the parallel support portion 11 and can move horizontally, and a layered inside of the main roof body 21. It is composed of three swivel roofs 22, 23, and 24 that are stored in an overlapping form and can be swiveled by paired circular orbits R1, R2, and R3, each of which is laid on the circular support portion 12. Has been done. Therefore, the circular orbits R1, R2, and R3 that guide these swivel roofs in a swivel manner are provided so as to be located above the straight orbits T1 and T1. In the main roof body 21, in order to store the three swivel roofs in a layered manner inside itself, the bearing plate portions 21a, whose entire ends extend inward in an L shape along the support surfaces 11a and 11a, 21a is provided, and the bearing plates at both ends are provided with arc tracks R1a, R2a, and R3a that support both ends of each swivel roof and allow the swivel roofs to enter and exit. Therefore, these arc tracks R1a, R2a, and R3a are provided so as to be located at the same level as the circular orbits R1, R2, and R3 on the circular support portion. In addition, the swivel center axes 25 of the swivel roofs 22, 23, and 24 are vertically installed on the zenith portion of the main roof body 21, and consideration is given so that the circular centers of the swivel roofs do not shift. Since the roof has a self-supporting arch shape that supports both ends, those vertical loads are not supported by the swivel center axis 25. As for the areas A and B shown in Fig. 3, as shown in Fig. 2, when the swivel roofs 22, 23, and 24 are linearly moved inside the main roof body 21 in a layered state. In addition, circular orbits R1, R2, and R3 are laid above the straight orbits T1 and T1, which hinders movement. A lifting device (not shown) is installed to support the circular orbit and lower it below the top of the straight orbits T1 and T1. Further, although not shown in particular, the main roof body 21 and the swivel roofs 22, 23, and 24 constituting the moving roof 20 have wheels 26 for self-propelling movement along the respective tracks. Each drive unit is equipped. The opening / closing operation and operation of the opening / closing roof configured in this way will be described below. FIG. 1 shows the closed state of the roof, in which the main roof body 21 is located directly above the stadium S, and the swivel roofs 22, 23, 24 are the respective circular orbits R1, R2, R3. It travels along to their closed position, which covers the space above Stadium S with a roof. On the other hand, in order to open the roof, the swivel roofs 22, 23, and 24 are swiveled in the direction opposite to the direction in which the roof closes, and are layered inside the main roof body 21 as shown in FIG. Stack. At this time, the elevating device lowers each circular orbit in the regions A and B below the tops of the straight orbits T1 and T1. Then, in this state, when the main roof body 21 is moved sideways along the straight tracks T1 and T1, that is, in the direction away from directly above the stadium S, and is moved to the position indicated by the virtual line in FIG. , The roof is fully open above the stadium S. When closing the roof from the fully open state of the roof, the procedure opposite to the above may be taken. According to the embodiment, the dome-shaped roof is divided into four butterfly-shaped roofs in a plan view, and three of them, the swivel roofs 22, 23, and 24, are provided on the circular support portion 12, respectively. , R2, R3, and these swivel roofs are the other roofs that swivel horizontally and linearly along the straight track T1 provided on the parallel support portion 11. The large-scale space above the stadium S will be opened 100% by a simple method in which the four roofs move horizontally and linearly while being stored inside the roof body 21. Become. In addition, since the main roof body 21 and the swivel roofs 22, 23, and 24 that make up the moving roof 20 all have an arch shape that supports both ends, compared to the arch shape of the cantilever beam and the swivel central axis support type. As a result, the design becomes economical, and the weight is reduced and the cost is reduced accordingly. In addition, the four roofs that make up the dome-shaped roof move in parallel, and some of them move in a swirling manner, which makes the design extremely novel and unexpected functionality for the viewer. It also creates an effect that makes you feel. In the embodiment, an example in which the dome-shaped roof is configured to be openable and closable by one arch-shaped main roof body and three swivel roofs is shown. It goes without saying that the number of swivel roofs may be four or more. "Effect of the invention" As described above, in the retractable roof according to the present invention, the dome-shaped roof is an retractable roof that can be opened and closed by a plurality of arch-shaped moving roofs that are vertically overlapped, and is a roof erection target. A pair of parallel support portions located on both sides and extending in parallel and a circular support portion located around the roof erection target and inscribed in the parallel support portion are provided, and the moving roof is provided on the parallel support portion. A main roof body that is supported at both ends by a provided track and can move horizontally, and a main roof body that is stored in a layered manner inside the main roof body, and both ends are supported by a track provided on the circular support portion. Since it is configured to have two or more swivel roofs that are self-supporting and swivel, a plurality of swivel roofs that form a part of the dome-shaped roof are along a straight track provided in the parallel support portion. It is a simple method in which all the roofs move horizontally and linearly while being stored inside one main roof body that travels horizontally and linearly. The scale space can be opened and closed 100%, which can reduce the influence of internal wind turbulence when the roof is open, and the main roof body and each swivel roof that make up the moving roof. Since all of them have an arch shape that supports both ends, it is an economical design compared to the cantilever beam and the arch shape that supports the turning center axis, so the weight can be reduced and the cost can be reduced accordingly. In addition, the four roofs that make up the dome-shaped roof can be moved in parallel, and some of them can be swiveled, making it extremely novel in terms of design. It produces an unprecedented excellent effect, such as the ability to create an effect that presages unexpected functionality.
