Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an openable / closable roof suitable for use in a circular or polygonal stadium, and is particularly required for improving the opening ratio of the roof and driving the opening / closing. The present invention relates to a parallel movement type retractable roof for reducing energy consumption.

<Prior Art> Conventionally, a parallel movement type roof as shown below has been well known as an openable roof for partially opening and closing a roof part covering a circular stadium.

In other words, this parallel-moving open / close-type roof is laid in parallel over the circular stadium surrounding the ground with a mortar-shaped stand standing above the facing stadium. The beams are erected, and a plurality of movable rectangular roofs that open and close the rectangular plane between the beams are provided between these beams so that they can move in parallel along the longitudinal direction of the beam, and both ends of the beam in the longitudinal direction. An accommodating portion for accommodating the movable roof by stacking the movable roof is provided on the part side, and the chord portion and the arc portion are provided on the beam and the outer peripheral wall portion of the stand on the outer side of the beam. It is configured with a fixed roof that is fixed.

Then, when the roof is opened, the plurality of movable roofs are moved to the left and right from the central portion of the beam, and the movable roofs are stacked and accommodated in the accommodating portion on the outer side of the stand. The roof of the shape is opened widely.

<Problems to be Solved by the Invention> By the way, in the above-mentioned conventional parallel movement type opening / closing roof, in order to obtain a larger aperture ratio, the installation span between the beams and the lateral width of the movable roof are taken as large as possible, It should be close to the diameter of a circular stadium.

However, in such a case, a space for unnecessarily covering the outside of the stadium with the movable roof when it is closed becomes large, and a large accommodation space for the movable roof when opened is required. In addition, when the span between the beams becomes long, it is necessary to add another beam in the middle to further divide the movable roof. Then, the added beam crosses over the center of the ground. There is a problem in that it becomes a visual hindrance and reduces the feeling of openness.

Furthermore, since the movable roof is moved away from the central portion in the longitudinal direction of the beam to the left and right sides of the beam, the movable roof arranged in the central portion has a large movement amount. In particular, if the beam is arched, the vertical lift will be large. Therefore, if the horizontal width of the movable roof is widened to increase the size of the movable roof, there is a problem that the energy required for opening and closing the movable roof in the central portion becomes large.

The present invention has been made in view of the above circumstances, and an object thereof is to employ a stadium having a circular or polygonal planar shape, which can have a large aperture ratio and can reduce energy required for opening and closing drive as much as possible. The purpose is to provide a parallel movement type retractable roof suitable for.

Still further, in this embodiment, the other first beam 8b described above is used.
Is a central portion 8b 'thereof located between the second beams 30 and 30.
Is formed so as to be freely detachable from both side portions 8b ″ of the second beam 30 and 30. The central portion 8b ′ is integrally attached to the side of the second movable roof 34, and It is adapted to be translated along with the second movable roof 36 along the longitudinal direction, i.e. the second movable roof 36 is fitted with the second beam 3.
With the opening 34 between 0 and 30 closed, the central portion 8b 'and its both side portions 8b "are engaged with each other and aligned in a straight line.

Although not shown, the first movable roofs 22a and 22b and the second movable roof 36 are opened and closed by well-known driving means such as a rack and pinion type, a wire pulling type, or a cylinder type. ing.

Therefore, with the retractable roof constructed as above,
In order to open the roof portion from the fully closed state to the fully opened state, first, the first movable roofs 22a and 22b are separated from the central top portion of the first beams 8 and 8 to the left and right, respectively, and the first movable roofs 22a and 22b are accommodated in the left and right housing portions 24 and 24, respectively. To the fixed roofs 28, 28 of the accommodating portions 24, 24 in a stacked state, and the opening 20 between the first beams 8, 8 is opened. After that, the second movable roof 36 is fixed to the accommodation part 38 of the fixed roof.
The second beam 30 is moved to and accommodated in the opening 42, and the opening 34 between the second beams 30 and 30 is opened. On the contrary, in order to close the fully open state to the fully closed state, first, the second movable roof 36 is closed, and then the first movable roofs 22a, 22b housed in the left and right housing parts 24, 24 respectively.
Close to each other and close.

Here, as described above, the first movable roofs 22a, 22b are moved laterally away from or closer to the outside of the stand portions 4a, 4a facing each other on both sides of the main stand portion 4b from the upper center portion of the ground 2. The first beam 8,8 above the stadium 6
The opening 20 between them is opened and closed, but at this time, the first arch-shaped beam
The amount of movement of the central movable roof 22a moving along 8, 8 is about twice as large as the amount of movement of the lateral movable roof 22b in both the horizontal and vertical directions.

On the other hand, the second movable roof 36 is a stand portion that faces the main stand portion 4b at right angles to the moving direction of the first movable roof 22.
It is moved toward the outside of 4c to open the opening 34 between the second beams 30 and 30 above the stadium 6 on the side of the other first beam 8b. The moving amount of the movable roof 36 is
The amount of movement of the side movable roof 22b of the first movable roof 22 is approximately equal to the amount of movement of the central movable roof 22a, which is sufficiently small in both horizontal and vertical directions.

For this reason, without increasing the span of the first beams 8 and 8 to make the first movable roof 22 larger than ever,
A large opening ratio of the roof above the stadium 6 can be secured. Then, in particular, since the central-side movable roof 22a, which has a large amount of movement in the horizontal and vertical directions of the first movable roof 22, does not increase in size, the energy required for opening and closing the movable roof 22 is reduced as much as possible, An improvement in aperture ratio can be achieved.

Further, in the present embodiment, the second beam 30, 30 is connected and the central portion 8b 'of the other first beam 8b located between the second beams 30, 30 is arranged with respect to both side portions 8b ". The second beam 30 and the second movable roof 36 are moved integrally with each other so that they can be engaged and disengaged separately from each other.
The central portion 8b 'of 8b is not left above the stand 4 and the ground 2 when the roof is fully opened, and does not obstruct the view, so that the open feeling can be further improved.

Furthermore, the arch-shaped first beam 8,8 and the second beam 30,30
Is supported at a position sufficiently higher than the outer peripheral wall portion 10 of the stand 6 by a pillar standing outside the outer peripheral wall portion 10 of the stand 6, so that the first beam 8, 8 and the second beam The curvature of 30,30 can be made as small as possible, and thus the amount of vertical movement of each movable roof plate 22a, 22b, 36 can be kept as small as possible, and the energy required for the opening and closing drive can be further increased. Labor saving can be achieved.

The parallel movement type retractable roof according to the present invention is highly useful for use in the illustrated stadium 6 having a circular plane shape or a stadium having a polygonal shape such as an octagon, but is not limited to this, and is not limited to this. Of course, it can also be adopted.

<< Effects >> In short, according to the present invention, the first beam installed in parallel above the stand portions facing each other in the stadium and the first beam are provided so as to be movable in parallel along the longitudinal direction thereof. A plurality of first movable roofs that are moved away from or closer to each other from the central portion to open and close the openings between the first beams, and a first movable roof that is orthogonal to the first beams and extends parallel to the outside of the stadium. Since the openable roof is configured to include the two beams and the second movable roof that is provided between the second beams so as to be movable in parallel along the longitudinal direction thereof to open and close the opening between the second beams. , Exerts the following excellent effects.

(1) The opening ratio of the roof portion above the stadium can be increased without increasing the size of the first movable roof by increasing the arrangement span between the first beams more than ever before.

(2) Since the first movable roof, which has a large amount of movement in the horizontal and vertical directions, does not become large in size, it is possible to achieve the improvement of the aperture ratio while saving the energy required for the opening / closing drive as much as possible.
