Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof suitable for an all-weather building such as an athletic stadium, a baseball stadium and the like.

<< Conventional Technology >> Generally, all conventional openable roofs have a laminated structure in which roofs are stacked in several stages, and these are simultaneously slid or run in a sliding manner to open and close the upper surface of the building.

The support means is provided with guide rails on the top or surface of the roof of the building and the lower layer of the building, and supports the guide rails so that they can travel on the guide rails.

These are designed so that when the movable roof is opened, they are overlapped with each other so that the area of the opening is large. Similarly, in order to increase the area of the opening, it has been considered to make the openable roof a folding structure.

<< Problems to be Solved by the Invention >> In the above-mentioned conventional openable roof, in order to support the roof members that are sequentially higher from the lowest roof member among the roof members that overlap with each other, the lower the roof member is, the more vertical the roof member is. The load is large and the strength needs to be very high. At the same time, the support structure and the moving power capacity need to be very large.

In addition, the structure of the roof tends to be complicated in the folding roof, and there is also a problem in the material and durability of the roof membrane.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an openable roof having a high opening ratio, which has an excellent open feeling and directly supports each movable roof with a structural frame of a building. It is in.

<< Means for Solving the Problems >> In order to achieve the above object, the retractable roof of the present invention is:
In order to cover the circular opening formed on the upper surface of the building with a dome-shaped roof so as to be openable and closable, the circular shape of the opening is divided into a plurality of parts at an equal arbitrary central angle, and a pair of divided edges thereof is formed. A plurality of arc-shaped sections each having a sector shape in which at least one of them has a fan shape protruding along the circumferential direction of the circular opening, and is curved with different radii of curvature so as to separate gaps in the vertical direction where they are vertically overlapped with each other. A movable roof is formed, and a plurality of movable roofs are rotatably coupled to each other with a single core shaft at a center position of the circular opening, with the gap therebetween, and the circular opening is formed in the building. A plurality of annular guide rails are laid horizontally along the outer periphery of the section and in accordance with the radius of curvature of each movable roof, while supporting the arc-shaped edge of each movable roof and guiding its rotational movement. .

<Operation> Each movable roof is supported by an annular guide rail that guides the movable roof in the rotating direction, so that each movable roof can be freely rotated without burdening the lower movable roof with supporting each movable roof. The top of the building can be opened and closed by moving it around the circular opening around the center of movement. In addition, the open position or the partially closed position can be selected by selecting the position where each moving roof stops.

By projecting at least one of the pair of divided edges of the movable roof along the circumferential direction of the circular opening, the stability of the support of the movable roof by the annular guide rail is increased, and thereby the movable roof is formed. There is no beam that straddles the circular opening to support it, and the annular guide rail is laid horizontally to prevent the natural fall of the moving roof and move with uniform driving force in the circumferential direction of the opening. The roof is moved.

In order to increase the aperture ratio, the center angle of the movable roof, which is radially divided and defined from the center of the circular opening, may be reduced. At that time, the support by only the annular guide rail laid along the outer circumference of the circular opening in the building corresponding to the radius of curvature of each movable roof tends to lack stability, so the At least one of the divided edges protruding along the circumferential direction of the circular opening has an extended length sufficiently stabilized by the support by the annular guide rail.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, basically, in order to cover the circular opening 3 formed on the upper surface of the circular outer peripheral wall 1 as a building with a dome-shaped roof so as to be openable and closable, the circular shape of the opening 3 is set at an equal arbitrary central angle. It is a fan shape in which a plurality of divided edges are defined, and at least one of the pair of divided edges protrudes along the circumferential direction of the circular opening 3, and further, a vertical gap in which these vertically overlap each other is formed. A plurality of movable roofs 4, 7, 9 each having an arch-shaped cross section and curved with different radii of curvature are formed so as to be separated from each other, and a plurality of movable roofs are formed by a single core shaft 5 at the center position of the circular opening 3. 4, 7 and 9 are rotatably connected to each other with the above-mentioned gap therebetween, and are provided on the circular outer peripheral wall 1 horizontally along the outer periphery of the circular opening 3 and correspond to the radius of curvature of each movable roof 4, 7, and 9. Let me move each roof 4,
A plurality of annular guide rails 2, 2a, 2b for laying and supporting the arcuate edges of each of the arcs 7, 9 while supporting them are constructed.

First, as shown in FIG. 1, an annular guide rail 2 is laid on the top end surface of a circular outer peripheral wall 1 which is erected circularly. Also,
The inside surrounded by the circular outer peripheral wall 1 forms a circular opening 3. The annular guide rail 2 has the outermost outer circumferences having different radii that make the center of the circular opening 3 concentric, that is, the annular guide rail 2 having the largest radius and the annular guide rail 2a having a smaller radius than this. Three annular guide rails 2, 2a, 2b of an annular guide rail 2b having an even smaller radius are laid, and each annular guide rail 2, 2a, 2b has one annular guide rail 2 that draws a large radius circle. It is located at the highest position, and is further lowered horizontally in the order of the annular guide rails 2a and 2b and laid horizontally.

Then, the planar shape of the movable roof 4 at the lowest position has a pair of linear portions from the center of the circular opening 3 to a halfway portion of a radial line extending radially outward at a central angle of 120 °,
Further, a pair of curved portions gradually approaching the intersection of the diameter line segment of the circular opening 3 having a central angle of 180 ° and the outer peripheral wall 1 from the end of the linear portion, and the outer peripheral wall 1 connecting the pair of curved portions to each other
And a fan-like shape surrounded by an arc-shaped edge portion. That is, the circular opening 3 has a fan shape in which the diameter line segment is notched so as to be curved and depressed from the center to one side. This is because such a shape has a long arcuate edge portion, and the entire movable roof 4 can be stably supported only by supporting the arcuate edge portion.

Thus, a part of the circular opening 3 is covered with the movable roof 4, leaving only a space extending from the center of the circular opening 3 at a central angle of 240 °. The remaining space is covered with another movable roof 7, 9 and the center of rotation of the movable roof 4, that is, the center of rotation of the movable roof 4, which coincides with the center of the circular opening 3, is provided with another movable roof 7, , 9 and a core shaft 5 for rotatably connecting to each other.

The remaining portion of the circular opening 3 that cannot be covered with the moving roof 4 is covered with two moving roofs 7 and 9. The moving roofs 7 and 9 are smaller than the moving roof 4 in terms of reducing the weight of the roof panel and reducing the moving power capacity. In addition, the number of moving roofs is reduced to two to minimize the number.

First, as shown in FIG.
Is substantially fan-shaped and defined by linear edges extending radially at a central angle of 120 ° from the center of the circular opening 3
Is located slightly outside the annular guide rail 2b and is stopped inside the annular guide rail 2. Then, of the pair of linear edges extending in the radial direction from the center of the circular opening 3, the edge located on the moving roof 4 side has a curve gradually asymptotically approaching from the tip toward the outer peripheral wall 1. Through the portions, the movable roof 7 is connected to the arc-shaped edge along the outer peripheral wall 1 and protrudes toward the movable roof 4 so that the movable roof 7 is stably supported on the annular guide rail 2a.

The movable roof 7 is supported on the annular guide rail 2a by a power bogie, and performs a rotating motion around the circular opening 3 along the circumferential direction of the guide rail 2a. The energy supplied to the power trolley is electric energy, and the trolley is of the trolley type, or the cable winding type uses a plurality of winding drums in the case of the cable winding type. To collect electricity at the lower surface of the trolley. The center of rotation is loosely fitted to the core shaft 5 fitted to the movable roof 4 so as to be freely rotatable. Since the annular guide rail 2a is located at a position higher than the annular guide rail 2b, the movable roof 7 is supported at a position higher than the movable roof 4, and the portion of the movable roof 7 that is loosely fitted to the core shaft 5 is also a core. In the portion of the shaft 5, the movable roof 4 is loosely fitted at a position above the portion where the movable roof 4 is fitted.

Next, FIG. 3 shows a case in which another movable roof 9 is attached, and the openable roof 10 covering the circular opening 3 is shown.
Is composed of a moving roof 4 and moving roofs 7,9. Third
As shown in the figure, the moving roof 9 is symmetrical with the moving roof 7, has a radius up to the arcuate edge slightly larger than the moving roof 7, and passes over the annular guide rail 2 to sufficiently cover the circular outer peripheral wall 1. The support means is supported on the annular guide rail 2 like a movable roof 7 so that it can run on a power bogie, and its rotation center is the core shaft 5.
Is freely rotatably fitted to a portion of the movable roof 7 and its position is provided on the movable roof 7.

These moving roofs 4, 7, and 9 are moving roofs on moving roof 4.
A movable roof 4 covering the circular opening 3 when the upper and lower wheels 7 and 9 run on the respective annular guide rails 2a and 2 so as to overlap with each other and consequently rotate around the core shaft 5 as a center of rotation. Portions other than the portion are completely open. This is shown in FIG. Each movable roof 4, 7, 9 can determine its supporting height position by the annular guide rails 2, 2a, 2b. In addition, the core shaft 5 plays a very important role in setting the height position of these movable roofs 4, 7, 9 because each can be maintained sufficiently stable by the support by the annular guide rails 2, 2a, 2b. It does not fulfill the purpose, but also serves as a path for transmitting power and information to each moving roof 4, 7, 9 and its shape is located on the upper outer peripheral surface as shown in FIG. It has a cylindrical shape with a flange 11 protruding therefrom. Moving roof 4,7, under this tsuba 11
The fitting or loose fitting portion 9 is formed in a ring shape, and this is externally fitted to the shaft portion of the core shaft 5. The top end of the core shaft 5 is covered with a cap 12.

<Effects> As described in detail above, according to the openable roof of the present invention, the circular opening formed on the upper surface of the building is covered with a dome-shaped roof so that it can be opened and closed, so that the openings have the same circular shape. A fan shape in which a plurality of divided edges are defined at an arbitrary central angle, and at least one of the pair of divided edges protrudes along the circumferential direction of the circular opening, and these are vertically overlapped with each other. Forming a plurality of movable roofs having an arched cross section curved with different radii of curvature so as to separate vertical gaps, and a plurality of the movable roofs having a single core axis at a center position of the circular opening. Are rotatably coupled to each other with the gap therebetween, and the building is horizontal along the outer periphery of the circular opening and corresponding to the radius of curvature of each of the movable roofs, and the arc-shaped edge of each of the movable roofs While supporting Since a plurality of annular guide rails that guide the rotational movement are laid, there is no need for one of the moving roofs to support the other moving roofs, and each moving roof is free independently in the circumferential direction of the circular opening. Can be moved to Therefore, the size and position of the opening can be freely selected. Also,
Since each moving roof does not need to bear the vertical load of the other moving roofs, it can be structurally very light. This has the advantage that the moving power capacity can be reduced, and that the room for supporting and extending the roof membrane and the material thereof can be sufficiently selected.

Furthermore, since the center of rotation of each movable roof is connected by a core axis, each movable roof can be stably moved, and at the same time, information is provided on the lower surface of each movable roof using this core axis. And power can be supplied.
