Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof of a baseball field, an athletic field and the like.

<< Conventional Technology >> Some recent baseball stadiums and stadiums have been provided with a roof having an air film structure so that they can be used regardless of the influence of weather. Further, various proposals have been made for an openable roof to obtain a sense of openness when the weather is fine.

The moving roof has a multi-stage structure, and the storage state accompanying the opening movement of the roof is a stacked type, making the storage space small,
Conversely, increasing the aperture ratio is an issue.

This openable roof supports the roof members that make up the roof so that they can move.
There are horizontal directions, each having advantages and disadvantages. However, in order to reduce the moving power capacity, the horizontal direction is advantageous, in which the moving roof is moved horizontally horizontally as it is.

《Problems to be solved by the invention》 When the retractable roof is moved horizontally as described,
One issue is how to reduce the storage space when the roof is opened, and when these roofs are moved to one end of the building, they have a stacked structure that fits vertically and fits in a small space. Advantageously, the dome roof has an end wall, which moves from one side to the other while maintaining the stability of the support or the height of the top of the opening above a certain level. Difficult in particular,
If the building requires a rectangular opening, such as an athletic stadium, it is not possible, or even possible, to place the end of the dome on a circular track and turn it 180 ° to the other. Had the disadvantage that the structure became difficult.

In addition, the structure of the foldable roof tends to be complicated, and there is also a problem in the material and durability of the roof membrane.

The present invention has been made in view of the above circumstances, and the object is that when the roof is opened, there is no beam at the opening, the opening feeling is excellent, and the openable roof with a high opening ratio is moved efficiently and stably. It is intended to fit in.

<< Means for Solving the Problems >> In order to achieve the above object, the openable roof according to the present invention has a substantially rectangular shape, and a long elliptical dome roof is divided into several parts in a direction perpendicular to the longitudinal direction. And one end in the longitudinal direction is a fixed roof fixed to the building, and the remaining roof part is sequentially divided by the divided roof part as it moves from the movable roof located at the other end to the fixed roof side. The fixed roof is configured so as to be able to be inserted and laminated inside the roof portion on the moving direction side, and the fixed roof is configured at a level position that fits inside the moving roof at the opposite end.

《Operation》 The roof is divided into more than two steps and moves almost horizontally in the axial direction intersecting with the dividing direction, and when moving and opening, it is adjacent to one end of the building to the other end. The matching roof portions move while overlapping each other, and overlap with each other in a multi-stage structure in the moving direction.

At that time, the fixed roof existing at one end of the roof is configured at a lower level position than the movable roof portion located at the other end, and thus can overlap each other.

The roof part divided in this way is accommodated so as to overlap the fixed roof at one end.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a side surface of a dome roof 1 having an openable roof according to the present invention. The dome roof 1 has a semicircular arc-shaped roof portion having end walls at both ends in the longitudinal direction of an outer peripheral wall 2 erected in an elliptical shape. And a fixed roof 3 is formed at the right end thereof, and a movable roof 4 is formed at the left end thereof.

The fixed roof 3 at the longitudinal end of the dome roof 1 and the roof part at the middle of the moving roof 4 are also divided into two transverse sections, and the width of the intermediate moving roof 5 adjacent to the moving roof 4 is The intermediate movable roof 6 that is wider than the movable roof 4 and that is located on the fixed roof 3 side of the intermediate movable roof 5 is wider than the intermediate movable roof 5.

 The width of the movable roof 4 is wider than the width of the fixed roof 3.

When the movable roof 4 moves toward the fixed roof 3 located on the opposite side opposite to the movable roof 4, the movable roof 4 covers and covers the fixed roof 3. Traveling wheels 7 are mounted on the bottoms of the movable roof 4, the intermediate movable roof 5, and the intermediate movable roof 6 so as to be movable, and the movable roof 4 is moved to maintain the end wall portion at a high level position. The support level of the roof 4 is configured to be very high, and the support level is reduced stepwise as the intermediate moving roofs 5 and 6 are sequentially adjacent in the moving direction. The top level of the fixed roof 3 is lower than that of the movable roof 4, but the intermediate movable roofs 5 and 6 are higher than the top level of the movable roof 4.

FIG. 2 shows a plan view of the dome roof 1. As can be seen from FIGS. 1 and 2, the fixed roof 3 is the smallest, and then the movable roof 4 and the intermediate movable roof 5 are sequentially larger in size. It has the largest structure. When these moving roofs are moved toward the fixed roof 3 while being supported by the traveling wheels 7, the moving roof 4 is accommodated inside the intermediate moving roof 5, and the moving roof 4 and the intermediate moving roof 5 are integrated into the intermediate moving roof 5. It fits inside the moving roof 6. The intermediate movable roof 6 moves toward the fixed roof 3 with the movable roof 4 and the intermediate movable roof 5 stored therein. For this purpose, guide rails 8, 8a are provided on the side surfaces near the bottom ends of the intermediate movable roofs 5, 6. Also, a guide rail 8c supporting the intermediate moving roof 6
Extend to both outer sides of the fixed roof 3. FIG. 3 shows a cross section. Moving roof on fixed roof 3 as shown
It overlaps in the order of 4,5,6.

The manner in which the roof opens will be described with reference to FIGS. 4 and 5. First, the movable roof 4 at the left end moves toward the intermediate movable roof 5 and gradually the guide provided inside the intermediate movable roof 5. The mobile roof 4 travels on the rail 8, and the movable roof 4 fits inside the intermediate movable roof 5.

Further, the intermediate movable roof 5 is moved in the guide direction of the guide rail 8a provided inside the intermediate movable roof 6 while the movable roof 4 is housed therein, and is accommodated in the intermediate movable roof 6.

Finally, the intermediate movable roof 6 moves toward the fixed roof 3 with the movable roof 4 and the intermediate movable roof 5 stored therein, and stops immediately before the end wall of the movable roof 4 hits the fixed roof 3. In this way, as shown in FIG. 5, the movable roofs 4, 5, 6 are stopped so as to overlap the fixed roof 3, and the top space of the building is opened. When the roof closes, it performs exactly the opposite of the movement just described. As can be seen with reference to FIGS. 3 and 5, in this embodiment, the bottom end level of the movement switch 4 is maintained at a considerably high position, so that the end wall portion is always maintained at the high level position. Have been.

<Effects> As described in detail above, according to the retractable roof of the present invention, the elliptical dome roof having a substantially rectangular shape on one side is divided into several parts in a direction orthogonal to the longitudinal direction, and the roof is divided into several parts. Since one end in the longitudinal direction is a fixed roof fixed to the building and the remaining roof part is a moving roof that moves so as to overlap in the fixed roof direction, it is cut off as the moving roof moves toward the fixed roof The formed roof portions are sequentially sunk into the inside of the roof portion on the moving direction side so that they can be stacked so that the storage space can be reduced. In addition, since it is possible to divide as much as possible in the direction perpendicular to the longitudinal direction, even a rectangular long oval dome roof can be moved horizontally from the other to one side, It is effective in that only opening and closing movements are sufficient.

The fixed roof has an outer shape level that fits inside the moving roof at the opposite end, so the bottom end of the moving roof's end wall, which is relatively opposite to the fixed roof, has a higher level. It is possible to configure the fixed roof and reduce the outer shape of the dome roof while reducing the outer shape of the building while keeping the end wall of the dome roof at a high level position and opening it when moving it There is an effect that it can be stored so as not to hinder the feeling or the line of sight.
