FIGS. 1 and 2 show the roof structure of this embodiment when it is extended and when it is stored. The fixed roof 1 is fixed to a foundation on the ground, while the movable roofs 2, 3 run on three rails 4 by means of wheels 5 provided at the bottom. At the front and rear edges of the fixed roof 1 and the front and rear edges of the movable roofs 2 and 3, locking members 6, 7, and 8 made of curved L-shaped steel are provided, as well as locking members 9, 10, and 11, respectively. The curved locking members 6 and 9, 7 and 10, and 8 and 11 are each integrally constructed by a pair of I-shaped steel base rods 12, 13, and 14. The base rods 12 of the fixed roof 1 are fixed on the foundation by appropriate means, and the base rods 13 and 14 are provided with wheels 5 and 5, respectively, which run on the rails 4. The upper parts of the fixed roof 1 and the movable roofs 2 and 3, which are composed of the base rod 12 and each curved connecting member, are connected to the bent portions 18 of the adjacent sides 16 and 17 of a large number of curved building boards 15. It is covered with curved roofs 1', 2', and 3' formed by bending the fastening part 20 of the bent part 19.

The building board 15 shown in FIGS. 8 to 12 is a long metal plate with a central portion 21 formed into an arc shape, and both ends 16 and 17 of the central portion 21 are bent outward perpendicularly. , the side edge of one side part 16 is bent inward at right angles to form a bent part 18, and the other side part 1
7 is bent outward at a right angle to form a connecting bent part 19 that connects with the bent part 18, and an end edge of the connecting bent part 19 is bent to form a fastening part 20, and the center The portion 21 is formed with a large number of long protrusions 22 that protrude outward or inward in the direction orthogonal to the longitudinal direction, and the both sides are provided with long protrusions 22 that protrude outward or inward in the direction orthogonal to the longitudinal direction, and A large number of small protrusions 2 are arranged at different positions that are difficult to alternate with the long protrusions 22 in the central part.
3 and 24, and the whole is curved inward in the longitudinal direction.

In this embodiment, the central part 21 of the long metal plate is formed into an arc shape, and both side parts 16 and 17 are bent vertically outward, and the whole is curved inward in the longitudinal direction, so that it can be used as a roof.

Sufficient strength can be maintained as a structure.

Furthermore, since the central portion 21 and both side portions 16, 17 are formed with a large number of protrusions 22, 23, 24 that protrude toward the outer surface or the inner surface and are orthogonal to the longitudinal direction, the central portion 21 and both side portions 16, 17 Each element has increased strength against compressive stress, and has great rigidity as a whole. Since both side parts 16 and 17 each have a bent part 18 for connecting adjacent curved building boards, a connecting bent part 19, and a fastening part 20, the connecting work can be performed very easily. No special expertise is required.

In addition, since the numerous protrusions protruding from the center portion 21 and both side portions 16 and 17 are provided at different positions that are difficult to alternate, it is possible to correctly bend the side portions 16 and 17 vertically when bending them. , the bent portion becomes a neat straight line, which improves the commercial value, and also has the effect of increasing airtightness when connected. In particular, if the spacing between the protrusions 23 and 24 between the side portions 16 and 17 is taken into consideration, a better connection can be achieved.

FIG. 11 shows another embodiment of the invention, in which long wavy protrusions 25 are provided on the central portion 21 and both side portions 16 and 17.
This is a construction board with small corrugated ridges 26.

The fixed roof 1 and the movable roofs 2 and 3 according to the embodiment of the present invention each have an opening 27 at the bottom, and the movable roof 3 at the front end is provided with a drive device 28 for driving the wheels 5. There is. This drive device 2
The wheels 5 of the movable roof 3 can run on the rails 4 by means of appropriate transmission means such as chains. As shown in FIG.
There are one pair each, and they ride on two rails.

The frontage of the fixed roof 1 in this example is approximately 22 m.
It is approximately 7 to 8 meters long. Therefore, the widths of the movable roofs 2 and 3 housed in the fixed roof 1 are approximately 21 m and 20 m, respectively, and the height of the opening is preferably approximately 2 m.

Next, the operation of this embodiment will be explained. When moving and extending the movable roof from the stored state shown in FIG.
8 to rotate the wheels 5, 5 of the movable roof 3 via appropriate transmission means. As a result, the movable roof 3 starts moving forward, and after moving forward by approximately that length, the rear locking member 11 of the movable roof 3 engages with the front locking member 7 of the movable roof 2 and moves. Continue moving forward while towing the roof 2. Moving further forward, the rear locking member 10 of the movable roof 2 engages with the front locking member 6 of the fixed roof 1, and the movable roof 2
The movement of and 3 is locked.

When storing the movable roofs 2 and 3 in the fixed roof 1, the operation described above is reversed, but when the movable roof 3 is stored in the movable roof 2, an engagement fitting (not shown) The two move together as they are pushed together, and are finally housed in the fixed roof 1 at the same time.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

(b) It has a retractable roof structure consisting of a fixed curved roof and multiple movable roofs that can be moved on rails by the driving force stored in the roof, so it can be installed at gateball fields or tennis courts. By using a drive device, the movable roof at the front moves forward on rails and extends the entire roof to completely cover the court surface, making it possible to enjoy playing even in rain or snow. The removable roof can be easily stored and play can be played without a cover.

In addition, since the entire structure has a curved roof, it is easy to play even in snowy regions during the winter, without the hassle of removing snow.

(b) The upper part of the curved roof is made by forming the central part of a long metal plate into an arc shape, bending both sides of the metal plate perpendicularly outward, and then curving the whole piece inward in the longitudinal direction. Since the metal plate has an arc shape in the center and an inwardly curved shape as a whole, the bending stress in the longitudinal direction increases dramatically, making it possible to maintain sufficient strength as a lightweight structure.

(c) In addition, the center and both sides have a large number of protrusions that protrude toward the outside or inside and are perpendicular to the longitudinal direction, so the center and both sides each have strength against compressive stress. It also has a large overall rigidity, so it can withstand heavy snowfall and strong winds. In addition, each side has a bent part that connects the adjacent curved building boards, a connecting bent part, and a fastening part, so the connecting work can be performed very easily, especially by a specialized engineer. does not require.

(d) Also, since the numerous protrusions protruding from the center and both sides are provided at different positions that make it difficult to alternate,
When bending both sides, the product can be bent vertically correctly, the bent portions become neatly straight, improving the product value, and when connected, the product has high airtightness and there is no risk of rain.

(E) The central part of the long metal plate is formed into an arc shape, and both sides of the metal plate are bent vertically outward, and the whole is curved inward in the longitudinal direction. Due to its circular arc shape and overall inwardly curved shape, bending stress in the longitudinal direction increases dramatically, and it has sufficient strength and is lightweight and can be installed as a roof without the need for special structures such as pillars or beams. There are no restrictions on location, and the lower part of the curved roof is open, so you can play without the need for special lighting.

(f) Furthermore, since the front edge of the fixed roof and the front and rear edges of the movable roof each have curved locking members, the driving device can be installed only on the front movable roof, and multiple movable roofs can be connected. The roof can be advanced on rails and, conversely, multiple movable roofs can be easily accommodated within a fixed roof.
