Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof for a large frame structure such as a stadium.

<< Prior Art >> In general, each of the conventional openable and closable roofs has a laminated structure in which the roofs are stacked in several stages, and these are slidably slid or run to open and close the top of the building.

For example, a method has been adopted in which traveling wheels are mounted on a beam supporting a roof so that a roof member runs on the beam, or the beam is configured to be expandable and contractible, and is moved and opened / closed together with the roof material.
These are designed so that when the movable roof is opened, the areas of the openings are widened by overlapping each other.

In addition, a horizontally parallel movable open / close roof has been proposed from the viewpoints of avoiding excessive stress concentration on the supporting part, being safe and easy to move, and having a small moving power capacity. .

<< Problems to be Solved by the Invention >> Due to the advantages described above, various types of horizontal parallel movement openable and closable roofs have rapidly been proposed although they are extremely recent.

However, in each of these already proposed horizontal translation type openable and closable roofs, the roof is divided into several parts from the center, and the roofs are drawn horizontally and on both sides.

For example, a fixed roof usually remains on the home side of a baseball field, but leaving the roof on the center side with this type of retractable roof is a nuisance to players and spectators, and it is open. It was disturbing me. The shade falling on the ground was also a hindrance.

Furthermore, the baseball stadium's entire site area, including the audience seats, is often the minimum necessary due to lack of space. However,
The roads for opening and closing the roof are usually larger than we would normally imagine, and require considerable width. This requires a large site for such a road. However, the reality is that it is difficult to even secure a site to be used for the road.

The present invention has been made in view of the above circumstances, and an object thereof is to open and close the roof in which the storage positions at the time of opening can be gathered in one place without compromising the opening ratio of the roof and various circumstances coming from the site area can be coped with. To provide.

<< Means for Solving the Problem >> In order to achieve the above object, the retractable roof of the present invention is a fixed roof provided to cover one end side in the longitudinal direction of the top opening of the building, and along the longitudinal direction. A movable roof that linearly moves and overlaps on the fixed roof to cover the remaining top opening so that the remaining roof can be opened and closed, a traveling carriage that is supported so that the movable roof can travel over the building, and a guide therefor. Rails, the moving roof is divided into odd numbers in a direction orthogonal to the moving direction, and the moving direction length of the central moving roof located at the center of the divided roof is approximately equal to the length of the fixed roof. The lengths of the side moving roofs located on both sides of the central moving roof are substantially equal to the length of the central moving roof, and the side moving roofs are open when the central portion is open. Go under the moving roof and move sideways on both sides Levels are sequentially added so that the roofs can be stacked one on top of the other in a state of being abutted against each other, and when the roof is closed, the central part of the roof moves to the fixed roof side. The vehicle is moved on guide rails arranged inside the roof guide rails, and when closed, the other side lateral movement roof located on the opposite side of the fixed roof is a relative upper floor movement. Transfer the rails on the inside of the roof from the guide rails on the building, store it in the moving roof at the upper level and move it in the opening direction. The guide rail for a side movable roof at the lower layer position is provided at a position higher than the guide rail of the movable roof at the upper layer position.

《Operation》 Each moving roof travels linearly along the longitudinal direction of the building on the guide rail via the traveling carriage and overlaps on the fixed roof installed at one end side to open the ceiling. Open up. At that time, a pair of side moving roofs on both sides of the center moving roof, which is divided into an odd number and located at the center, sunk into contact with each other in a butt state, and overlapped at one place on the fixed roof to fit. The top opening is wide and wide.

Also, one side moving roof located on the opposite side of the fixed roof at the time of blockage, when moving open, dives underneath the moving roof which is relatively adjacent to and relatively located at the upper layer and is provided at a high position inside thereof. After moving to the rail, it will be housed in the upper part of the moving roof in the upper position and then moved as a unit, so that the internal volume of the lower part of the moving roof in the upper position will not be narrowed, so the effective volume in a narrow site The opening area can be expanded while securing as large as possible.

«Examples» Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

Fig. 1 shows a baseball field 1 which is a building constructed on a substantially rectangular site with the longitudinal axis extending from the home base to the center.
As you can see from the figure, the width of the baseball field 1 on the outfield seat side in the tip direction is narrower than the width on the infield seat side, and the baseball field 1 also has a width on the outfield seat side according to the shape of this site. Is narrowing.

The top opening of the baseball field 1 is covered with an odd number (three in this embodiment) of movable roofs 2, 3, 4 and a fixed roof 5 provided on one end side in the longitudinal direction. Moving roof 2,
3 and 4 are configured to move linearly along the longitudinal direction of the baseball field 1 in the axial direction connecting the home base and the center side, and the fixed roof 5 is arranged on the rightmost side of the baseball field 1, that is, the back net side. I am configuring. These roofs 2, 3, 4, and 5 are deployed on the top surface of the baseball field 1 to form a semi-elliptical shape, bow in the direction orthogonal to the moving direction, straddle the top opening on the ground, and move each The base ends of the roofs 2, 3 and 4 are supported by guide rails 6 and 6a parallel to the moving direction. That is, the movable roofs 2, 3 and 4 are movably supported on the guide rails 6 and 6a via traveling carriages attached to the base ends thereof.

The movable roofs 2, 3, 4 are shown in Figs. 2 to 4 below.
It is shown together with the fixed roof 5 so that the features of the above can be seen.

As can be seen from the figure, the side moving roof 4 is arranged at the left end of the central moving roof 3 having the largest width, height, and length, and the side moving roof 2 is arranged at the right side. are doing.

The side moving roofs 2 and 4 have the same length in the moving axis direction and are approximately half the length of the central moving roof 3. That is, the length of the central moving roof 3 is twice the length of the side moving roofs 2 and 4, and is substantially equal to the length of the fixed roof 5.

As shown in FIG. 5, these movable roofs 2, 3 and 4 are movably supported by guide rails 6, 6a and 6b, respectively, and these guide rails 6, 6a and 6b are attached to the baseball field 1. A pair of rails is provided at both ends along the longitudinal direction, and the rails are provided at both ends.

Figure 5 shows the state where the moving roof of the baseball field 1 has been removed. Since the width of the site is narrow, if the guide rails 6 and 6a are extended straight from the back screen side toward the sensor, there will be a space to install the foul pole. It's gone.
Further, since the end portion on the center side is narrow, the guide rail 6a cannot be extended as it is. Therefore, the guide rail 6b that supports the side moving roof 4 is laid only on the left end side of the baseball field 1 by the length of the side moving roof 4, and in the part where the width is wide at the right end of the guide rail 6b. A guide rail 6a of the widest central moving roof 3 is laid out toward the outside. The ground 7 and the spectator seats 8 are inflated toward the outer side of the baseball field 1 by the width of the central movable roof 3, that is, as close to the guide rail 6a as possible so as to be expanded. The guide rail 6 is laid inside the guide rail 6a with the same width as that of the guide rail 6b so that the right end of the expanded portion can be pulled out toward the back screen. Therefore, the side moving roof 2 has the same size and width as the side moving roof 4. That is, the side moving roof 2
Runs on the guide rail 6.

The side moving roof 4 is supported by a guide rail 6b as shown in FIG. 2, and a gable plate 9 is provided on the left side of the side moving roof 4 to be located at the left end of the baseball field 1.

As shown in FIG. 3, the height of the side moving roof 4 is lower than the height of the central moving roof 3, and the level of the guide rails 6b supporting the side moving roof 4 supports the central moving roof 3. It is at a higher level than the existing guide rail 6a. In such a state, the side moving roof 4 fits inside the central moving roof 3 as shown in FIG.

The central movable roof 3 is provided with the carrier rails 10 supported by brackets inside the lateral movable roof 4 in order to accommodate the lateral movable roof 4, and the lateral movable roof is moved from the guide rail 6b toward the carrier rail 10. 4 moves. Therefore, the level of the carrier rail 10 installed inside the side movable roof 4 is in the direction of the extension axis of the guide rail 6b, and the level is always kept the same. A device for maintaining the same is shown in FIG.

A connecting plate 11 is provided so as to project from the leading end of the guide rail 6b, and a pair of hydraulic jacks 12 are provided vertically so that the end of the guide rail 6b on the side of the transport rail 10 that is in contact with the guiding plate 6b sandwiches and supports the connecting plate 11.

FIG. 7 shows the moving state of the movable roofs 4 and 3 together with the operation of the connecting plate 11 and the hydraulic jack 12. Fig. 7 (A)
As shown in FIG. 2, first, the side moving roof 4 first moves slightly to the right before the side moving roof 4 tries to move to the right, that is, in the direction in which the side moving roof 4 fits inside the central moving roof 3. At this point, the hydraulic jack 12 clamps the connecting plate 11 from above and below. In this way, the guide rail 6b and the transport rail 10 are continuously integrated. The guide rail 6b
It is not always necessary to move the side-moving roof 4 to the right, even though it is a slight amount, when the two are integrally connected to each other for the purpose of level adjustment of the carrier rail 10 and the carrier rail 10.

Next, the side moving roof 4 is moved as it is while being guided by the transport rail 10 of the central moving roof 3, and is made to go under the central moving roof 3 and accommodated therein. Further, the central moving roof 3 is directly attached to the side moving roof 4 as a transport rail.
It can be moved to the right according to the guide rail 6a while being placed on 10. At that time, it is necessary to firmly fix the side movable roof 4 on the transfer rail 10 of the central movable roof 3, and the same device as the connecting plate 11 and the hydraulic jack 12 as shown in FIG. It is good to install in 4. That is, if the connecting plate 11 is provided on the side moving roof 4 and the hydraulic jack 12 is provided on the center moving roof 3 and the side moving roof 4 rides on the transport rail 10, the center moving roof 3 The connecting plate 11 of the side moving roof 4 may be sandwiched and supported by the hydraulic jack 12.

As described above, the guide rail 6b of the side movable roof 4
Has no problem even if it cannot be extended due to the presence of the foul pole and the seats 8.

Next, the side moving roof 2 will be described. As shown in FIG. 4, the side moving roof 2 is configured so that the side moving roof 2 can freely travel on the guide rail 6 running in parallel with the guide rail 6a at the same level. The height of the roof is almost the same as that of the side moving roof 4 described above.

Therefore, as shown in FIGS. 7 (B) and 7 (C), with the side moving roof 2 placed on the fixed roof 5 at the rightmost end, the central moving roof 3 is moved to the side. When the side moving roof 2 is moved to the right side with the partial moving roof 4 as it is, the side moving roof 2 is housed inside the central moving roof 3 and is brought into contact with the side moving roof 4 in a butted state so as to face each other.
The height of the fixed roof 5 is lower than that of the side moving roof 2. Therefore, when the moving roofs 2, 3, 4 are moved to the rightmost side, they are below these moving roofs 2, 3, 4. That is, the fixed roof 5 is made to be the lowest layer, and the fixed roof 5 is sequentially laminated in the laminated type. When the movable roofs 2, 3 and 4 are closed, the movement opposite to the above is performed.

<Effect> As described in detail above, according to the retractable roof of the present invention, each movable roof travels linearly along the longitudinal direction of the building on the guide rail via the traveling carriage, and once The top opening is opened by superimposing it on the fixed roof installed on the part side. At that time, a pair of side moving roofs on both sides of the center moving roof, which is divided into an odd number and located at the center, sunk into contact with each other in a butt state, and overlapped at one place on the fixed roof to fit. The top opening is wide and wide. Therefore, in the case where the building is a baseball field or the like, assuming that the back net side is the direction in which the guidance is superimposed and accommodated, the first base side, the third base side, and the center direction can be completely opened.

Also, one side moving roof located on the opposite side of the fixed roof at the time of blockage, when moving open, dives underneath the moving roof which is relatively adjacent to and relatively located at the upper layer and is provided at a high position inside thereof. After moving to the rail, it will be housed in the upper part of the moving roof in the upper position and then moved as a unit, so that the internal volume of the lower part of the moving roof in the upper position will not be narrowed, so the effective volume in a narrow site It is possible to increase the opening area while securing as large as possible.

Also, inside the central moving roof at the upper level position, a transfer rail that is continuous with the guide rail of the side moving roof at the lower level position is laid, and the moving roof at the lower level position moves with the moving roof at the upper level position. Since it can be done, the guide rail of the moving roof on the lower layer position side can be omitted.

Furthermore, since the transfer rail in the moving roof in the upper layer position, which accommodates the moving roof in the lower layer position, is provided at a position higher than the guide rails for the moving roof in the upper layer position, together with the guide rail for the moving roof in the lower layer position, At least the lower side of the moving roof on the upper layer position side can secure an effective volume by the width (thickness) of the moving roof on the lower layer position. This is effective not only for the thickness of the moving roof on the lower layer side, but also for the guide rails and the equipment for laying the guide rails required for its movement that do not project inside the moving roof on the upper layer side. The effect is that the area can be made wider. Furthermore, even if there are multiple roofs in the lower position with respect to the upper position, the roof heights of which are the same level, the lengths of these roofs should be shorter than those of the moving roof in the upper position. Since it fits on the same level inside the roof in, the number of laminated layers is reduced,
The height of the seated state is reduced, and the wind pressure resistance is improved as well as the appearance.

Also, installing another independent moving roof with the same roof height as that of the moving roof in the lower layer, which moves on the transfer rail inside the moving roof in the upper layer position, minimizes the transportation rail facility and minimizes the upper layer. There is an advantage that the structure of the moving roof on the side can be simplified.
