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] Facilities for sports such as baseball, soccer, tennis, etc. and halls that are used as venues for various outdoor events are provided with roofs that cover the entire area from the sides to the top of these facilities. is being carried out.

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 players and spectators in the stands, but on the other hand, it has the advantage of being able to comfortably play and watch 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 can open or close part or all of the roof depending on the weather, season, etc.

There are various types of movable roofs that have been proposed in the past, which can be opened and closed in different directions. There is something like the one described in Japanese Patent No. 58=176335.

That is, as shown in FIG.
J Roof Split the roof in the same direction, and each divided roof part v
Both ends of Ja, b, c, and d are rotatably supported by one support part e, and each roof member a.

The radius from the support part e to the roof surface of b, c, and d is different, and the roof member a with the largest radius is fixed, so that the other roof members are placed inside the roof member a, c, If the roof member d is inserted in order and overlapped in order to open a part of the roof, or if the roof member d with the minimum radius is fixed, other roof members c, By polymerizing in the order of b and a, a part of the roof is opened.

[Problems to be Solved by the Invention] However, in the conventional roof described above, the diameters of the plurality of divided roof members a, b, c, and d are sequentially increased or decreased from one side to the other in the opening/closing direction. , when the roof is closed, as shown in Figure 7, roof members a and b
Since the edge of roof member a is located on the outside of the roof member in the middle of the downward slope, there is a risk of rainwater, etc. infiltrating, and each roof member a, b, c, d Since both ends of the are supported by shaft support, it is necessary to stack them on top of each other and attach them to the shaft so that they do not interfere with each other when opening and closing.
The greater the number of divisions, the longer the shaft of the support part e is required.

Therefore, the present invention aims to eliminate the risk of rainwater infiltration when the roof is closed by expanding the divided roof blocks, and also to enable both ends to be supported without using a shaft.

[Means for Solving the Problems] In order to achieve the above object, the present invention arranges a dome-shaped roof body to be formed by a plurality of divided roof blocks cut along cutting lines extending in the same direction, Among the above roof blocks, both ends of each roof block are fixed so that the negative roof block can be fixed and the remaining roof blocks can be rotated.
It is supported by a guide part provided on a fixed wall at the periphery of the facility, and the rotating roof block is made to have the same diameter and has a different diameter from the fixed roof block, and the roof block in the center is made to have a large diameter, and A rotation drive mechanism is provided between a rotating roof block and a fixed roof block. A sealing device, drain plate, etc. will be installed at the abutting portions of the roof blocks having the same diameter as a mechanism to prevent rainwater from entering.

[Function] By moving the rotatable roof block so that it overlaps the fixed roof block, a part of the roof body is opened, allowing sunlight and wind to enter the facility surface. On the other hand, by moving the rotatable roof block and closing the roof body, it becomes possible to create a facility with a roof, where both people can play sports without any problems. When the roof body is closed, it covers the outside of the roof block at a higher position or the roof block at a lower position, so there is no risk of rainwater infiltrating even if the seal is not sufficient.

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

Figures 1 to 6 show an embodiment of the present invention, in which a fixed wall 1 at the periphery of a facility where sports and various events are held.
Above, a plurality of roof blocks 2a, 2b, 2c, and 2d (four blocks are shown in the drawing) each having a shape like a roof with a semicircular cross section divided in a direction perpendicular to the cross section,
They are arranged in the same direction and supported to form a roof body 3. In other words, the roof block 2 is divided into four parts.
a.

Among 2b, 2c, and 2d, 2a and 2d are fixed and arranged on the fixed wall 1, and the roof blocks 2a and 2
Both ends of the roof block d are fitted and fixed into the guide member 4 fixed on the fixed wall 1 with the anchor bolt 5 as shown in FIG. 3, and the remaining roof block 2b is fixed.

Assuming that 2C can be rotated, sliders 8 at both ends thereof
is movably inserted into a groove 6 formed in an arc shape on the inner surface of the guide member 4, as shown in FIG. The roof block 2b has the same radius of 2d and also rotates.

The radius of 2C is also the same, and the rotating roof block 2b
, 2c is made larger than the diameter of the fixed roof blocks 2a and 2d, and the roof block 2b rotates.

2C is superimposed on the outside of the fixed roof blocks 2a, 2d. The rotating roof block 2b,
2c has a width such that its lower edge partially overlaps the outer side of the lower edge of the fixed roof blocks 2a and 2d when the roof block 3 is closed, and has the same diameter. Since the roof blocks 2b and 2c are closed, the joints between the roof blocks 2b and 2c are butt joints, but in order to ensure the sealing properties of these joints, they are constructed as shown in FIG. 4. That is, a bonding material 10 having a curved groove 11 along the entire length is attached to the end face of the truss 9 on the abutting side of one roof block 2b, and a plurality of sealing rubbers 12 are attached to the groove 11. A bonding material 13 having a convex portion 14 over the entire length is attached to the end face of the truss 9 on the abutting side of the other roof block 2C, and the convex portion 14
A rotating roof block 2b has a sealing rubber 15 attached to the surface thereof so as to come into contact with the rubber rubber 12.

20 are butted against each other to fully open the roof body 3, the recessed groove 11 and the convex portion 14 fit together, and the sealing rubbers 12 and 15 are brought into contact to perform sealing,
Furthermore, a drain plate 16 is attached to either one of the roof blocks 2b or 2C (the roof block 2b side is shown in the drawing) via a sealing material 17 so as to cover the joint,
To prevent rainwater from entering when the roof body is closed.

Further, in order to rotate the rotating roof blocks 2b, 2C, and n with respect to the fixed roof blocks 2a and 2d, a rotation drive device 18 is provided between each of the roof blocks 2a and 2b, and between 2C and 2d. This rotary drive device 18
As shown in the figure and FIG. 6, a fixed roof block 2a,
A beam 22 having a T-shaped cross section and protruding outward through the rim 20 and the roof material 21 is fixed to the 2d truss 19, and a rail 24 having a rack 23 on the surface is attached to the outer surface of the beam 22 over the entire length. On the other hand, the rail 24 is attached to the truss 9 on the side of the rotating roof blocks 2b and 2c.
A pinion gear 25 that meshes with the upper rack 23, a motor 26, and a reduction gear 27 that connects the pinion gear 25 and the motor 26 are attached, and the pinion gear 25 is rotated by the drive of the motor 26 to move the rack 23 on the rail 24.
By rolling along the roof blocks 2b and 2C, the roof blocks 2b and 2C can be moved outside the fixed roof blocks 2a and 2d.

It should be noted that the rails 24 provided on the fixed roof blocks 2a, 2d are effective, for example, if they are provided in the center as shown in FIG. 2, since only one rail 24 is needed, the rails 24 can be installed at any desired location. Further, the portion where the beam 22 penetrates the rim 20 and the roofing material 21 has a seal structure.

Now, when the roof blocks 2a, 2b, 2c, and 2d are closed as shown in FIG. 1, the lower edges of the rotating roof blocks 2b and 2C are connected to the fixed roof blocks 2a and 2d.
Since it is located on the outside of each upper edge of both roof blocks 2a
There is no risk of rainwater entering between 2C and 2d and between 2C and 2d. Therefore, a sealing device between the two may be unnecessary or simple, and manufacturing becomes easier. Furthermore, since the joints between the rotating roof blocks 2b and 2C are shaped as shown in FIG. 4, rainwater can be prevented from entering by the drain plate 16 and the rubber seals 12 and 15.

In the closed state, the upper part of the facility is covered by the roof 3, so sports and other events can be held even during rain or snow.

Next, when opening a part of the roof body 3, the roof block 2b is
and 2C are opened on the left and right.

In this case, when the motor 26 is driven, the reduction gear 1
0 = 1 since the pinion gear 25 is rotated via 27
The pinion gear 25 meshes with the rack 23 on the surface of the rail 24 and is rotated, so that the roof blocks 2b and 20 begin to move along the rail 24. Since the roof blocks 2b and 20 are configured to have a larger diameter than the fixed roof blocks 2a and 2d, they are moved as a whole to wrap around the fixed roof blocks 2a and 2d, and the upper part is opened. At this time, both ends of the rotating roof blocks 2b and 2c, which are the centers of rotation, are movably guided and supported by the grooves 6 of the guide member 4 on the fixed wall 1, so they can be moved smoothly without a support shaft. can.

When the roof blocks 2b and 2C are fully opened, the space between the fixed roof blocks 2a and 2d on both sides is opened.
It is possible to play sports by letting sunlight directly into the facility surface, and especially when the facility surface is covered by tennis courts 1 to 1, the fixed roof blocks 2a and 2d on both sides prevent wind from entering the facility from the sides. This makes it possible to play without being affected by the wind, and the fixed roof block 2a
By placing the audience seats on the 2d side, spectators can avoid receiving direct sunlight.

Note that the present invention is not limited to the above-mentioned embodiment. For example, in FIG. 1, the two roof blocks 2b and 2c in the center are made rotatable, and the roof blocks 2a and 2d on both sides are fixed. However, conversely, the two roof blocks 2b and 2c in the center are fixed and the roof blocks 2a on both sides are fixed.

2d may be rotated. In this case, the two central roof blocks 2b and 2c can be made into an integral structure, and by opening the roof blocks 2a and 2d on both sides, direct sunlight can be avoided even in the scorching sun, and wind can be taken in from the sides. In addition, even on rainy days, the central part can be covered, making it possible to play sports while reducing the influence of rain. Further, the number of roof blocks may be other than four, and it goes without saying that various changes can be made without departing from the gist of the invention.

[Effects of the Invention] As described above, according to the movable roof of the present invention, both ends of a plurality of roof blocks each having a shape in which a roof body is divided into a plurality of parts,
The fixed roof blocks are movably supported by guide members installed on the fixed wall soil around the facility, and some of the roof blocks are fixed while the remaining roof blocks are rotated. Different, and even more rotational.
The roof blocks have the same radius, a sealing device is installed at the joint, and a drive device is provided to rotate the rotating roof blocks, eliminating the risk of rainwater entering when the roof is closed. In addition, only the center part or only both sides can be opened and closed at will, making it useful for various events.Furthermore, the supporting parts at both ends can be inserted into the guide device without using a shaft. Since it is supported, excellent effects such as smooth movement can be achieved.
