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 a roof provided with 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 in order to obtain an open feeling in fine weather.

The moving roof has a multi-stage structure, and the storage state accompanying the opening movement of the roof is a stacked type, so that the storage space is reduced and the aperture ratio is increased. The moving direction of the moving roof that constitutes the openable roof has vertical and horizontal directions, each of which has advantages and disadvantages, but the horizontal direction is advantageous for the purpose of reducing the moving power capacity.
This moves the moving roof horizontally horizontally as it is.

《Problems to be solved by the invention》 When the openable roof is moved horizontally, one problem is how to reduce the storage space when the roof is opened. It is common to adopt a laminated structure that can be accommodated by being overlapped vertically, and there is a drawback that storage stability is lacking. In addition, since the movable roof that constitutes the openable roof needs to be stably supported so that it can be opened and closed, there is a drawback that the opening lacks the feeling of opening when the beam is left in the opening.

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

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object the advantage that when the roof is opened, beams are not left at the opening, the opening feeling is excellent, and the openable roof having 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 plurality of dome roofs formed in a spherical shape on the upper surface of a building and divided at appropriate positions on the center and on both sides of the center. The movable roof is moved horizontally in a direction away from the center dividing position, and the movable roof is housed in such a manner that these movable roofs are stacked one on top of the other at the end of the building. At the dividing position at the center of the dome roof, the dome roof is vertically divided, and at the other dividing positions, the dome roof is divided at an upward inclination from the central dividing position toward the separation movement direction.

In addition, since the cross-sectional side shape of the movable roof is forwardly inclined, the roof is provided with a guide rail for guiding and supporting the upper roof on the lower roof surface located at the lower layer when overlapping in order to improve its stability, A part of the roof is movably supported by the guide rail.

<< Operation >> A plurality of moving roofs formed by dividing a spherical dome roof on the upper surface of the building at the center and at appropriate positions on both sides of the center are horizontally moved in a direction away from the center division position, At the end of the building, these movable roofs are stacked so as to be stacked one on top of the other and are housed, and in particular, among the division positions forming the movable roof, at other division positions other than the center division position, Since the moving roof is divided and formed with an upward slope sequentially from the center division position in the direction of the separation movement, when the roof is opened, as it goes toward the top of the building, that is, on the roof It becomes possible to form a state in which the open end of the roof is cut out toward the outside of the building as going toward the building.

 Therefore, the aperture ratio and the feeling of opening can be improved.

In addition, since the cross-sectional shape of the upper roof that overlaps the lower roof has a shape that surrounds the lower part when viewed from the side, it is easy to fall in the moving direction, so A guide rail for guiding and supporting the upper roof is provided, and the lower roof and the upper roof are structured to support each other via the guide rail.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, basically, a plurality of movable roofs 4 formed by dividing a dome roof 1 formed in a spherical shape on the upper surface of a building composed of an outer peripheral wall 2 and a fixed roof 3 at appropriate positions at the center and both sides of the center. , 4,4a, 4a are moved horizontally in the direction away from the center dividing position, and these movable roofs 4,4,4a, 4a are stowed upside down at the edge of the building. Moving roof 4,4,4
a, 4a is formed by being vertically divided at the center division position of the dome roof 1, and is formed by being sequentially inclined upward from the center division position in the separating movement direction at the other division positions. You.

FIG. 1 shows a plan view of a dome roof 1 having a retractable roof according to the present invention. The dome roof 1 has a fixed roof 3 that covers a roof surface of an outer peripheral wall 2 that is erected in an elliptical shape, and is formed at the center of the fixed roof 3. Moving roof movably covering the opening
4a. When the dome roof 1 is viewed in a plan view as shown in FIG. 1, the moving roofs 4 and 4a are divided right and left from the center of the dome roof 1, and this divided one is further divided right and left from the center, and the central side of the dome roof 1 That is, the roof members on the top side are the moving roofs 4, 4 and the left and right roof members outside the roof members are the moving roofs 4a, 4a, respectively. The divided cross sections of the movable roof 4 and the movable roof 4a are defined so that the divided vertical sections are inclined forward in the left and right movement directions, and the movable roof 4 overlaps the movable roof 4a when opened.

Of these movable roofs 4 and 4a, the movable roof 4a is provided with a trolley 5 at both end positions and an end near the outer diameter in the center, the movable roof 4 is provided with a trolley 5 at both end positions, and the trolley 5 is a fixed roof. The vehicle travels on a guide rail 6 provided in parallel on the guide rail 3.

In this way, each movable roof 4, 4a moves horizontally on the rail 6 attached horizontally on the fixed roof 3, thereby reducing the moving power capacity as compared with the vertical moving direction. A relatively small configuration is sufficient. At this time,
It is sufficient for the supporting carriage 5 of the movable roof 4a located on the outer peripheral side of the dome roof 1 to move horizontally on the fixed roof 3 respectively, but the upper movable roof 4 that moves so as to cover the fixed roof 3 is left and right. When moving horizontally in the direction, the bogie 5a on the central outer diameter side may become unstable because it separates from the surface of the lower moving roof 4a, and the lower layer moving for the purpose of solving this point An auxiliary track 7 having a horizontal top surface protrudes from the center point of the roof 4a and in the left-right direction, and a guide rail 6a is attached to the top end face of the auxiliary track 7. Then, the carriage 5a of the movable roof 4 travels horizontally on the rail 6a attached to the auxiliary roadbed 7, and as a result, the movable roof 4a is moved at each point of the carriage 5 at both ends and the central carriage 5a. We support stably.

The side view of the dome roof of FIG. 1 is shown in FIG. 2, and it can be seen that the fixed roof 3 covers the seat 8 and the movable roofs 4 and 4a cover the central arena 9. The movable roofs 4, 4a are moving on the fixed roof 3 when the top of the arena 9 is opened. Also, since the divided cross section of the moving roof 4 and the moving roof 4a is defined in the moving direction, that is, in the forward and backward direction with respect to the left and right direction, the outer diameter of the moving roof 4 when the moving roofs 4 and 4a are fully opened. As for the side end face, the radius length of the bottom end face becomes shorter than the radius length of the roof surface, and the moving roof 4
Can be moved to the outer diameter side of the dome roof 1. Therefore, the aperture ratio is improved. On the other hand, the cross section of the moving roof 4a side is inclined forward in the moving direction of the moving roof 4 and the radius of the bottom end face is shorter than the length of the roof portion. The radius length of the bottom end face is longer than the length, which means that when the top of the arena is viewed from the audience seat 8 at the opposite position when the movable roof 4a moves on the fixed roof 3 Roof that the line of sight blocks the angle of inclination
As a result, the opening side ends of the 4 and 4a move to the outside of the dome roof, and it is possible to reduce the inclination angle of the line of sight, thereby improving the feeling of opening. The same applies to the other embodiments shown in FIGS. 3 and 4, but in this embodiment, the shape of the moving roof 4b corresponding to the moving roof 4 and the moving amount of the moving roof 4a are slightly different. .

The moving roof 4b defines both ends linearly, unlike the moving roof 4b in which both ends of the moving roof 4 are formed in a curve in accordance with the curvature of the opening of the top surface of the arena 9. Therefore, the carriages 5 at both ends of the moving roof 4b are different from the moving roofs 4 in which the respective positions of the carriages 5 located at both ends are shifted. It is also possible to use a multi-axle bogie cascaded in the direction of the movement axis.
This makes it possible to reduce the number of guide rails 6 by one. That is, it is possible to reduce a total of two by reducing one by one at both ends of the movable roof 4b.

Furthermore, in order to move the lower moving roof 4a further to the outside of the building, a rail 6b for guiding and supporting the carriage 5 located at the center point and the outer radial end of the moving roof 4a is connected to the outer peripheral wall 2a.
It extends and protrudes in the outer diameter direction. The extended projecting guide rail 6b is supported by a projecting beam 10 projecting outside the outer peripheral wall 2.

The projecting beam 10 and the auxiliary track 7 have substantially the same structure, but details of the auxiliary track 7 are shown in FIG.

The auxiliary track bed 7 is provided with a beam support 11 along the outer surface of the movable roof 4a, and the beam support 11 supports a beam 12 which also serves as a track bed.

Further, an inverted T-shaped T-shaped rail 13 is attached on the beam 12 which also serves as a roadbed, and a wheel stopper 14 for forcibly stopping the carriage 5a is installed at an end thereof. This wheel stopper
14 is a trapezoidal small beam from the horizontal surface of the T-shaped rail 13
Secured with anchor bolts passing through 12.

<Effects> As described in detail above, according to the retractable roof of the present invention, a plurality of movable roofs formed by dividing a dome roof formed in a spherical shape on the upper surface of the building at the center and at appropriate positions on both sides of the center are provided. Is moved horizontally in a direction away from the center dividing position, and at the edge of the building, these movable roofs are stacked one on top of the other on a retractable roof,
The movable roof is formed by dividing vertically at the center of the dome roof, and is divided and formed at the other divided positions with an upward slope sequentially from the center of the dome toward the separation movement direction. Therefore, when the heavenly space of the building is viewed from the audience seats, the inclination angle of the line of sight is reduced, and there is an effect of improving the feeling of opening.

In addition, a guide rail for guiding and supporting the upper roof is provided on the lower roof surface located on the overlapping lower layer, and a portion of the upper roof is supported by the guide rail on the lower roof surface at this lower position so that it can be guided freely. The stability of the roof is improved, and the roof can be moved horizontally in a stable manner.
