Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof used for an all-weather building suitable for an athletic stadium, a baseball stadium, and the like.

<< Conventional Technology >> Generally, all conventional openable roofs have a laminated structure in which roofs are stacked in layers, and these are slid or run in a sliding manner to open and close the top of a building.

For example, there has been a means of attaching a traveling wheel to a beam for supporting a roof and running the roof member on the beam, or a method in which the beam is configured to be extendable and retractable and moved and opened and closed together with the roof member. These are designed so that when the movable roof is opened, the movable roofs are overlapped with each other to increase the area of the opening.

However, it is necessary to stably support the movable roof constituting the openable roof so that it can be opened and closed. Therefore, when a beam is left in the opening, there is a drawback that the opening lacks an open feeling.

Therefore, moving roofs that open and close the top space of the building for the purpose of increasing the aperture ratio and shortening the opening and closing time are connected by vertical shafts, and this shaft connection point moves in the circumferential direction of the building, There has been a retractable roof that supports these movable roofs with running wheels or the like along a movement trajectory when the movable roof moves on a fixed roof in accordance with the movement of the connection point.

《Problems to be solved by the invention》 When a large opening area is taken for a large-span column-free space such as an athletic stadium or a baseball stadium, and this is covered with a moving roof,
The area of the moving roof itself has become very large, and a considerable amount of reinforcement has been required as a reinforcing structure for supporting the support points of the roof, and at the same time, a large power capacity for moving the roof has been required.

In order to reduce the moving power capacity as much as possible, it is desirable to use a horizontal moving method that does not involve natural fall on the moving roof, and to minimize not only the power capacity problem but also the structural weight as much as possible It is desirable to use a moving roof.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an openable roof capable of realizing a movable roof with a minimum required opening area and a movable roof that does not fall freely. It is in.

FIG. 1 shows a plan view of the openable roof 1 which is formed in a substantially circular shape and has a top surface formed horizontally from an arbitrary point of a diameter segment of the outer wall 2 toward the outer wall 2. A fixed roof 4 is installed leaving an opening 3 that opens in a fan shape at an opening angle of 90 °.

The fixed roof 4 has a size of 270 ° extending around the above-mentioned arbitrary point with respect to the opening 3 having an opening angle of 90 °, and the fixed roof 4 is relatively large. On the contrary, the roof part has a relatively small area.

The opening 3 is in the shape of a fan, and the key position of the fan is located at the above-mentioned arbitrary point on the diameter line of the outer wall 2, that is, at the center of the tip of the fixed roof 4. A pivot shaft 5 is installed at the center of the tip of the fixed roof 4 which is the main part of the fan-shaped opening 3. And
The turning roof 8 and the turning roof 14 for opening and closing the opening 3 are:
The range covering the opening 3 is divided into right and left by a straight line connecting the center position of the arc-shaped portion of the fan-shaped opening 3 and the rotating shaft 5, that is, the diameter line segment of the outer wall 2, and the dividing line (diameter) The fixed roof 4 is further divided by a straight line extending from the left and right vicinity of the intersection point where the outer wall 2 intersects with the outer wall 2, and thus the outer wall 2
The rotating roof 8 and the rotating roof 14 are formed on the left and right sides of the diameter line segment, respectively, and the rotating roof 8 on the diameter line side is pivotally attached to the rotating shaft 5 so as to be rotatable. A traveling vehicle 6 is provided at a tip portion on the opposite side to the rotating shaft 5 side, that is, a portion placed on the outer wall 2 and supported on the outer wall 2, and the traveling vehicle 6 is further rotated on the outer wall 2. A traveling guide rail 7 is provided to support the outer wall 2 to move in the circumferential direction on the left and right with the shaft 5 as the center of rotation. In this way, the rotating roof 8 rotates around the rotating shaft 5 in the circumferential direction of the outer wall 2. In order to support the rotatable roof 8 so as to be freely rotatable, it is not sufficient to support the traveling carriage 6 and the rotatable shaft 5 only at two points. A supporting cart 9 is installed at the corner between the two, and is supported by a guide rail 10 installed on the fixed roof 4 along a locus of the rotating roof 8 rotating.

At each corner point of the swivel roof 14 outside the swivel roof 8, there is provided a bogie that supports the swivel roof 14 so that the swivel roof 14 can run freely.

FIG. 2 shows a state in which the top surface of the opening 3 is fully opened. Since the revolving roof 8 and the revolving roof 14 can open and close freely without restraining each other, various opening and closing procedures can be selected. However, in any case, the fully opened state is as shown in FIG.
With the center of rotation as a pivot point, the movable roof 14 moves in the direction away from each other and is accommodated, and the swiveling roof 14 also swings in the opposite direction and accommodates on the fixed roof 4.

<Effects> As described in detail above, according to the openable roof of the present invention, the inside of the flat circular outer peripheral wall is covered with the fixed roof so as to cover the fan-shaped opening section formed so as to be openable and closable. The roof of the fan-shaped opening is constituted by a pair of swiveling roof and swiveling roof formed on both sides thereof with its diameter passing through the center position of the fan-shaped opening as a line symmetric axis, A half of the arc length is an arc-shaped base, and the fixed roof side hypotenuse is formed in a triangular shape on the fixed roof, and a power bogie is arranged on the arc-shaped base to be movable along the outer peripheral wall. A guide trolley is arranged at the apex angle portion with respect to the arcuate base, and can be moved on the fixed roof along the movement of the arcuate base, and can be swung from the opening to the fixed roof. The outer wall has the above-mentioned swirl along its circumferential direction. A turning guide rail that guides the movement of the power bogie on the arcuate bottom of the roof is laid horizontally, and a guide rail that guides the movement of the guide bogie at the apex of the turning roof is provided on the fixed roof. Laying horizontally parallel to the guide rails, the rotating roof has one side along the line symmetry axis as the bottom side, and its fixed roof side hypotenuse is overlaid on the fixed roof, and the other hypotenuse is overlaid on the swiveling roof. The fixed roof side end of the bottom is rotatably connected to the fixed roof via a rotation shaft, and a traveling vehicle is provided at the other end of the base and the fixed roof is fixed. A support trolley is arranged on the oblique side of the roof, and is rotatable to the fixed roof while overlapping on the revolving roof from above the opening, and further on the fixed roof and outside the outer peripheral wall, respectively. Along the path of rotation of the rotating roof, Since the guide rail and the travel guide rail for guiding the movement of the traveling cart are laid horizontally, firstly, the opening is formed into a fan shape to secure a large spread area of the fixed roof, thereby opening and closing the opening. The turning roof and the turning roof can be made small. Therefore, it is possible to reduce the weight of these moving roofs and swiveling roofs.

Second, the pivoting and swiveling roofs can be moved in a horizontal movement manner without natural fall. The power capacity can be reduced by such an opening and closing system that performs horizontal movement.

Third, since the swiveling roof and the swiveling rotatable roof are supported separately from each other, they can be opened and closed separately, and at the same time, various openings can be formed. it can. That is, not only the full opening but also a partial opening can be variously selected.

Fourth, as described above, the rotating roof and the swiveling roof are made smaller by making the opening part fan-shaped to secure a large spread area of the fixed roof and to make the rotating roof and the swiveling roof smaller. Since it only moves along the circumferential direction of the circular outer peripheral wall, it is possible to reduce the portion of the moving rotary roof or swivel roof protruding outside the outer peripheral wall.

Fifth, the opening has a fan shape to secure a large spread area for the fixed roof, and the swiveling roof or rotating roof can be moved only a relatively short distance in the left-right direction about the axis of symmetry. The opening and closing movement can be completed in a short time, and at the same time, the energy consumed for this can be reduced.
