Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof that covers the upper part of a facility such as a sports facility, and particularly relates to a movable roof that can be opened and closed depending on the weather, season, etc. It is something.

[Prior art 1] In sports facilities such as baseball, soccer, tennis, etc., and in outdoor halls used as venues for various events, roofs are often provided to cover the entire upper side of these facilities. It is being done.

Providing a roof to cover the surface of the facility allows sports, games, entertainment, and other events to be held without any problems even during rain or snow, and also blocks the strong sunlight even under the scorching midsummer sun, making it possible to enjoy the inside of the facility. This has the advantage of being able to maintain a comfortable space for the players and spectators in the bleachers, but on the other hand, it also has the advantage of being able to maintain a comfortable space for the players and spectators in the stands, but on the other hand, it is difficult to enjoy playing and watching games comfortably under the warm sunlight in mild climates such as spring and autumn. The problem is that when you want to do something, you can't because it's covered by a roof.

In order to solve these problems, movable roofs have been proposed that allow part or all of the roof to be opened or left unused depending on the weather, season, etc.

There are various types of movable roofs that have been proposed in the past with different opening and closing directions, but a hemispherical or nearly hemispherical roof is divided into multiple roof members, and each roof member is attached to the roof. Examples of devices that are opened and closed by moving horizontally using the top as a fulcrum are shown below.

In other words, ■ The roof members are divided at equal intervals around the top of the hemispherical roof, and each can be rotated around the pivot point at the top, and by opening any roof member at any location, sunlight can be absorbed throughout the day. In addition, as an opening/closing mechanism, a guide roller is installed on the lower end of the rotating roof member.
A roof member placed on a guide rail on a ground base and moved by pulling with a wire, feeding with a rack binding nion, etc. (Japanese Unexamined Patent Publication No. 58-17
No. 6337), ■ An inner roof body with a part of the cap shape removed in a fan shape is placed inside the outer roof body with a part of the cap shape removed in a fan shape, making it double, and the outer roof body and the inner roof body are The fan-shaped removal parts formed on the inner roof body are overlapped or closed by relative rotation to open or close the upper part of the facility, and as a rotation mechanism of the inner roof body, a track provided on the outer wall of the facility and a track provided on the outer wall of the facility are used. Equipped with a sliding mechanism consisting of a drive device etc. installed on the outer periphery of the inner roof body via legs so that it can be moved along the track (Japanese Patent Application Laid-Open No. 63-40032); Divide into fan-shaped blocks, fix some of the fan-shaped blocks, and make the remaining fan-shaped blocks pivotable around the center of the roof top. Part of it is opened (Utaka 63-196)
13) etc.

[Problems to be Solved by the Invention] In each of the above-mentioned conventional systems, a part of the roof moves laterally to open and close, letting in warm sunlight to enjoy sports, or letting in a gentle breeze to enjoy competitions. Although it has the advantage of allowing you to enjoy entertainment,
176337 @ The drive mechanism for rotating the roof members is simple, so it is not suitable for large roof members, and the sealing performance of the parts where the roof members butt each other is poor. Although this is important, there is a problem that no consideration is given to this point, and in the case described in Japanese Patent Application Laid-Open No. 63-40032 (■), an outer roof with a part of the cap shape removed to form a fan shape. The inner roof body, which has the same structure as the main body, is arranged in double layers so that a part of the roof opens only when the fan-shaped removed parts overlap.The opening area is narrow, and the inner roof body itself is large. It cannot be opened unless it is rotated, so a large amount of power is required to rotate it, and
Because it is necessary to arrange the outer roof body and the inner roof body double,
It will be a big deal.

In addition, in the method described in Japanese Utility Model Application No. 1963-19613, one of the adjacent fan-shaped blocks is fixed and the other fan-shaped block can be rotated, so when the roof is opened, it is necessary to open it. There is a problem in that the sunlight can only be brought in from any location.

Therefore, the present invention aims to divide the dome-shaped roof into a plurality of parts in the radial direction from the apex, so that it can be opened at any point and can be opened and closed smoothly.

[Means for Solving the Problems] In order to achieve the object F, the present invention arranges a plurality of fan-shaped roof blocks to form a dome-shaped roof body, and fixes some of the roof blocks. a support provided on the fixed roof block so that the remaining roof block can be rotated along a fixed wall around the facility, and the upper end of the rotatable roof block can be rotated around the center of the top end of the roof body; The roof block is rotatably supported on a shaft, a drain plate is provided at the boundary between the fixed roof block and the rotating roof block, and a mechanism for rotating the rotatable roof block is provided.

Further, the driving mechanism is provided between the lower end of the rotatable roof block and the fixed wall, or between the upper end of the rotatable roof block and the upper end of the fixed roof block.

[Operation] When the rotatable roof block is rotated around the support shaft at the top of the roof and overlapped with the fixed roof block, a part of the roof is opened.

There is always a difference in level between the fixed roof block and the rotatable roof block, but there is a drain plate on the fixed roof block side, so
There is no chance of rainwater getting in. By changing the open position of the roof as appropriate, the facility can be used for sports or as an outdoor stage with only the stage covered.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

21 is the roof block receiving material 17 and the fixed roof block 2C
, 2d.

Furthermore, a base beam 22 is attached to the lower end of each of the rotating roof blocks 2a, 2b with connecting bolts 23 as shown in FIG. Pinion gears = 10-24 are rotatably attached at intervals, and the pinion gears 2
Separate pinion gears 25 and 26 are rotatably installed in the inner and outer directions (radial direction) across the 4, and the pinion gear 24 in the center is connected to the motor 27 installed on the base beam 22 via a power transmission gear 28. , the pinion gear 24 is rotationally driven by the motor 27. On the other hand, the rotating roof block 2a is attached to the fixed wall 1 around the facility.

The three rails 29, 30, 31 are fixed with anchor bolts 32 in correspondence with the three sets of pinion gears 24, 25, 26 in the internal and external directions, respectively, over the range in which 2b moves when opening and closing, that is, over the entire circumference. Rail 29, 30.3
1. The above pinion gear 24.25.2 is attached to the teeth carved on the surface.
6 are engaged with each other, and the pinion gear 24 in the center is rotated by the motor 27 to form a rack-shaped rail 29.
．． Roof blocks 2a and 2b are moved using 30.31 as a guide to open and close.

Now, when the roof blocks 2a and 2b are expanded and the roof body 2 is closed, the upper part of the facility is covered by the roof body 2, so
Sports competitions, entertainment, concerts, etc. will be held inside the dome. When the roof body 2 is closed, the rotating roof blocks 2a and 2b are butted against each other, but the third
As shown in the figure, the space between the two is sealed, and the outside thereof is covered with a drain plate 11, and the top part is also a fixed roof block and a rotatable roof block 2a, as shown in FIG.

Since the gap between the holes 2b and 2b is covered with the drain plate 20, it is possible to more reliably prevent rainwater from entering.

To open a part of the roof body 2, the motor 27 shown in FIG. Make sure to roll along the line. As a result, the other pinion gears 25, 26 also roll along the corresponding rails 30, 31, so that the roof blocks 2a, 2b smoothly roll on the rails 29, 30, 31 around the support shaft 19 shown in FIG. Movable and fixed roof blocks 2c.

It enters the inside (lower side) of roof blocks 2d and polymerizes, opening the roof blocks 2a and 2b. At this time, the base beam 22 runs along the three rails 29, 30, and 31, so it can move smoothly.

If the adjacent roof blocks 2a and 2b can be opened as in this embodiment, for example, half of the facility surface can be used as a pool and the other half as a rest area, so that the pool is directly under the open roof. If you do so, you will be able to play in the pool directly exposed to the sun's rays, and you will also be able to take a break in the shade under a fixed roof. The acoustic effect can be enhanced by installing a stage under the roof and seating for the audience under the open roof.

It should be noted that the present invention is not limited to the above-described embodiments; for example, the rotating roof blocks 2a, 2b
A pinion gear 24.2 serves as a drive mechanism to rotate and move the
5.26 and rack-shaped rails 29° and 30.31, however, it is also possible to use a system in which the wheels move on the rails. Fig. 7 shows an example of this, in which a right-angled or nearly right-angled corner part is provided around the entire circumference of the fixed wall 1 around the facility, and an arc-shaped rail like one-fourth of a cylinder is installed at the corner part. 33 are fixed with anchor bolts 34, and a plurality of wheels 35 are arranged in the inner and outer directions on the base beam 22 attached to the lower ends of the roof blocks 2a and 2b having a truss structure. gear 36 to one of the wheels 35.
is fixed, and the motor 37 installed on the base beam 22 and the gear 36 are connected by the power transmission gear 38, and the motor 37
The roof blocks 2a, 2b are moved together with the base beam 22 on the rails 33 by rotating the wheels 35. In this case as well, since there are a large number of wheels in the outward and outward directions, the roof blocks 2a, 2b can be moved smoothly with a small amount of power.

Further, FIGS. 8 to 10 show still another example of a drive mechanism for moving the roof blocks 2a, 2b, which is provided near the top of the roof. That is, at the top of the roof body 2 (1 hellas 14 constituting a fixed roof block)
A ■-shaped rail 14=39 is arranged in a circular plane on the lower surface of the roof block, and wheels 40 to be engaged with the rail 39 are rotatably supported on the rotating roof blocks 1 to 4 of the roof blocks 2a and 2b. , the motor 41 installed on the truss 4 and the arbitrary wheel 40 are connected to the power transmission gear 4.
The roof blocks 2a, 2b are connected via rails 39, and by rotating wheels 40 by driving a motor 41, the roof blocks 2a, 2b are moved in the circumferential direction while suspended from rails 39. According to this type, it is sufficient to simply provide guides for the roof blocks 2a, 2b on the fixed wall 1 around the facility.

Furthermore, in the above explanation, a fixed roof block is integrally formed with a semicircular planar shape, and two adjacent roof blocks 2a and 2b are rotated. However, for example, a fixed roof block may also be used. It may be made rotatable so that the position of the fixed roof can be changed at will, and furthermore, the number of divisions of the roof block can be changed at will.

[Effects of the Invention] As described above, according to the movable roof of the present invention, the dome-shaped roof body is divided into fan-shaped roof blocks so that some of the roof blocks can be opened and closed. The roof can be opened or closed at any point depending on the situation, and this opening and closing can be done smoothly using a small drive source installed on the roof blocks. By providing a sealing device and a drain plate at the abutting portion, excellent effects such as being able to prevent rainwater from entering between the roof blocks that are opened and closed can be achieved.
