DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable roof which can be structurally constructed simply.

[0002]

2. Description of the Related Art A conventional openable roof has a roof covering the top of an arena that rotates horizontally (fan type), moves up and down or turns to one end, and is made of a light-permeable material. It was covered with lumber and metal plates. When the movable roofs configured to be movable can be stacked in a plurality of stages and overlap each other and fit in one end of the building, the top of the arena is opened, and when the top of the arena is moved to cover the top of the arena, It blocks the top of the building. If you open it in fine weather, you will get an environment close to the outdoors.

[0003]

In the conventional openable roof, the roof covering the top of the arena is composed of several movable roofs, and these roofs extend in the plane direction with each other. It is difficult to assemble each moving roof on the ground and raise them to the roof level because the moving roofs overlap and move or overlap at one end, and because of the large span structure. . Furthermore, when the positions of the movable roofs overlap with each other and the supporting points are shared, or when the roof is at a lower level, the supporting points of the roofs located above the moving roofs are even more so. Therefore, in addition to performing the construction of the framework of the moving roof at high altitudes, the roofing work is the same, and the construction is difficult together with the moving structure of the roof. Nor was it cheap. The present invention has been made in view of the above circumstances, and its purpose is equivalent to a moving roof, and it is possible to assemble the corresponding roof member on the ground and attach it to the building, as well as to cover the roof membrane etc. on the ground. It is an object of the present invention to provide a retractable roof having a simple structure.

[0005]

When the frame is opened right and left from the center of the upper end with the rotatable shaft attachment portion of the frame base constituting the arch beam as the rotation axis, the arch beam on the roof is opened right and left. That is, since the arch beam is constituted by a pair of left and right frames, the roofs are opened and closed by rotating the frames in opposite or opposite directions. In order to determine the maximum position associated with this opening and closing, either the locking piece or the long hole is provided on the frame, and the frame is stopped at the position where the frame is abutted on both the left and right to form an arch. That is, the length
The position where the locking piece hits the end of the hole is the stop position . Such a closed position is supplementarily obtained by the strength of the stop positioning device and the frame itself, and also by the tension of the wire stretched inside the arch beam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In the openable roof according to this embodiment, arch beams 3 are intermittently arranged in the girder direction, and a roof film is stretched on the surface thereof. FIG. 1 shows details of the arch beam 3. The arch beam 3 is formed by forming two arch materials having different radii of curvature with a pipe, arranging the two arches vertically, and arranging the two in a tapered shape, connecting the two with a ladder material 15 to form an arch. It is composed of a triangular frame 5 having a simple bow shape.
That is, the two frames 5-5 are configured to stand upright, with the tapered side facing upward, and to form the arch beam 3 with their leading ends facing each other. The installation position of the frame 5 may be the upper end surface of the outer peripheral wall 7 surrounding the arena, or may be at a level substantially close to the ground surface by providing a fixed pedestal on the ground surface. A corner portion on the inner peripheral side of the bottom of the frame 5 is rotatably supported by a shaft 9 toward the inner side of the upper surface of the outer peripheral wall 7. A roof opening / closing winch 11 is provided near the outer side of the upper surface of the outer peripheral wall 7, and the unwinding end of the wire 13 wound around the winch drum is engaged with a corner on the outer peripheral side of the bottom of the frame 5. In response to the unwinding and winding of the wire 13, the frame 5 performs an elevation angle movement with the shaft 9 as a rotation center point. This elevation movement moves synchronously with the frame 5 located at the opposing position, and the arch beam 3 opens and closes in a flip-up manner. Furthermore, since the arch beams 3 are intermittently arranged in the girder direction of the building, it is necessary that these arch beams 3 rotate synchronously at the same angle, and the winch drums of the winches 11 are connected to each other by a universal joint. Then, a control system that starts up with one power source or synchronously starts up several power sources and feeds back the rotation angle of each frame 5 is configured. Further, the ladder member 15 located at the bottom of the frame 5 is provided with a locking piece 17 protruding in the lateral direction, and a swingable long hole material extending from the upper surface of the outer peripheral wall 7 toward the locking piece 17. The locking piece 17 is inserted into the long hole 19. This constitutes a stop positioning device 20 that determines the maximum angle at which the frame 5 should stop tilting in the depression direction. The locking piece 17 moves in the long hole of the long hole material 19 with the elevation movement of the frame 5, and the locking piece 17 is moved at the maximum depression position of the frame 5.
Corresponds to the upper end inside the long hole of the long hole material 19. Sheaves 21 are provided at regular intervals inside the frame 5-5, that is, on the inner peripheral side of the arch beam 3-3. The wire 23 guided and supported by the sheave 21 is for preventing fluttering of the arch beam 3. One end of the wire 23 is fixed to the base of one frame 5, and the other end is a tensioner 2 installed near the rotation shaft 9 of one frame 5.
5, the wire 23 is always towed, giving a strong tension to the wire 23. The wire 23 prevents the frame 5-5 from lifting in the elevation direction and, together with the stop positioning device 20, restricts the movement of the frame 5 in the depression angle direction. Such a flutter prevention device is useful in terms of the effectiveness of simply forming the butting ends of the opposing frames 5-5 and leaving a gap such that they do not collide with each other when closed.

FIG. 2 shows a butt end portion of the frame 5-5. A rainwater catch 27 extending from one frame 5 so as to cover the other frame 5 is attached to the leading end of the frame 5, and a rainwater shield whose tip is slightly upwardly bent upward from a level below the frame 5. Reference numeral 29 protrudes from the end edge of the frame 5 on the opposite side of the rainwater receiver 27. Also, a cylindrical member made of an elastic material, for example, synthetic rubber, that is, a joining member 31 formed of a tube is fixed to the tip of the frame 5-5 under the rain water receiver 27 and the rain water shield 29. . Therefore, when closing the pair of left and right frames 5-5 constituting the arch beam 3, the locking pieces 17
At the same time as the upper end of the long hole material 19 hits the upper end of the long hole material 19, and the joint members 31 hit each other to be distorted, thereby absorbing an impact at the time of closing. Thereafter, tension is further applied to the wire 23, and the frame 5-5 is applied.
The distal end of itself is bent toward the inner circumferential side of the arch, and the joining members 31 are tightly adhered to each other to exert a water stopping effect, and the frame 5-5 does not swing vertically. That is, even if the frame 5 is moved by wind or the like, the cable wires 23 resist. The rain water receiver 27, the rain water shield 29, and the joining member 31 are provided between the tips of the adjacent frames 5 after the frame 5 is built in the girder direction. That is, they are laid in the direction of the digits. Although briefly described above, FIGS. 3 and 4 show a case where a solid foundation 33 is constructed on the ground and the arch beam 3 is immediately installed on the ground without depending on the outer peripheral wall 7. As shown in FIG. 4, a solid base 33 is struck on the ground, and the inner corners at the bottom of the frame 5-5 are rotatably mounted on the shaft 9 on both sides of the solid base 33. The outer wall 7 shown in FIG. Is the same as a building with 3 and 4, the space formed inside the arch beam 3 is the indoor space. The seat 35 is provided at an angle to the base of the frame 5 while the frames 5 are adjacent to each other. FIG. 5 shows a state in which the roof film 37 is stretched. As shown in the figure, a roof membrane 37 is stretched so as to cover the space between the arch beams 3 and 3. It may be divided with the receiver 27 and the like. A semi-circular girder 39 is provided between the arch beams 3 to support the roof membrane 37 integrally with the arch beams 3. Therefore, a valley is formed immediately above the arch beam 3, and a valley gutter for draining rainwater is attached here. The opening on the surface of the outer peripheral wall 7 formed between the wife side and the arch beam 3 is closed by a hanging curtain 41. The entrance 43 is provided on the wife side of the outer peripheral wall 7.

[0008]

As described above in detail, according to the openable roof of the present invention, the frame constituting the arch beam is divided into left and right from the center of the upper end, and each frame base is rotatably mounted on the shaft. Then, this arch beam itself has a structure that flips up and down to the left and right, and such arch beams are intermittently arranged in the girder direction, so if you assemble each frame on the ground and stand upright Good. Therefore, as a result of a reduction in work at height, there is an effect that the work and the construction period become easier. In addition, the frame that constitutes the beam only has to be rotated by pulling it around the pivot axis with a wire or the like, and it is a very simple opening and closing mechanism compared to a structure that runs while supporting the roof with a traveling cart etc. Administration is simplified. Since the arch beam is composed of a pair of left and right frames, it is important to determine the position where the left and right frames abut, from the perspective of preventing roof distortion, and a long hole that allows the frame to rotate, Since the rotation angle of the frame is regulated by the locking piece that locks the elongated hole, the closed position of the frame is ensured, and the performance is improved in terms of safety and maintenance of the roof shape. . Furthermore, since the wire is stretched and tightened along the inside of the arch beam, the tension of the wire presses the frame inward, which has the effect of preventing the roof from fluttering due to wind power.
