Abstract

PURPOSE:To stably store an open type roof with good moving efficiency by linearly moving a center point of a turning roof on a circumferential, to the peripheral side of the roof on a guide rail on a fixed roof. CONSTITUTION:A level difference to form a layered structure on a fixed roof 2, is provided on each turning roof 3, 4 arranged symmetrically to the right and to the left around a diametrical line. A guide rail 6 to determine a moving direction thereof is linearly provided along the diametrical line of the roof, so as to linearly move a point of turning support. When the roof is to be opened, the turning roofs 3, 4 are opened up in such a way that they are overlapped on the upper part of the fixed roof, at the time of moving the point supported by circumferential rails 7, 7a to the side of the fixed roof 2, as well as the point supported by the guide rail 6 and an outer peripheral rail 8, in such a way that they follow the movement of the turning roofs. An open type roof of high opening ratio can thus be stably stored with a good moving efficiency.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to retractable roofs for baseball stadiums, track and field stadiums, etc.

(Prior Art) Recently, some baseball stadiums and stadiums are equipped with roofs made of air membrane structures so that they can be used regardless of the influence of the weather. Furthermore, various proposals have been made regarding retractable roofs to provide a sense of openness on sunny days.

The movable roof has a multi-tiered structure, and as the roof opens, the storage condition becomes stacked, making it a challenge to reduce the storage space and increase the open area ratio. The movable roof that makes up the retractable roof can move in either the vertical direction or the horizontal direction, each of which has its advantages and disadvantages, but when the purpose is to reduce the moving power capacity, the horizontal direction is advantageous. The movable roof is moved horizontally from side to side.

(Problem to be solved by the invention) When a retractable roof is moved horizontally as described above, one problem is how to reduce the storage space when the roof is opened. When moved to one end, the stacked structure is advantageous in terms of space because it can be stacked on top of the other, but it has the disadvantage of being bulky and lacking stability in storage.

In addition, since it is necessary to stably support the movable roof so that it can be opened and closed, if a beam is left in the opening, there is a drawback that the opening lacks a sense of openness.

Furthermore, folding roofs tend to have complicated roof structures, and there are also problems with the material and durability of the roof membrane.

The present invention was made in view of the above circumstances, and its purpose is to provide an excellent sense of openness without leaving any beams in the opening when the roof is opened, and to provide efficient and stable movement of a retractable roof with a high opening ratio. It is intended to be contained within.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention includes an eave-like fixed roof that slightly covers a part of the inner peripheral edge of a flat circular roof, and the remaining part is covered with a flat circular roof. The fixed roof is defined left and right along a diameter line passing through the center of the fixed roof, and the portion defined left and right is defined at the intersection of the diameter line and the tip edge of the fixed roof extending like an eave in the radial direction. The part is turned into a revolving roof.
These have a level difference in which the rotating roof on the side closer to the fixed roof overlaps with the fixed roof, and the rotating roof on the side closer to the diameter line is the top layer, and each rotating roof has a level difference on the surface of the fixed roof. A corner located at the leading edge of the center of the fixed roof is movably supported by a plurality of horizontal guide rails arranged in parallel along the diameter line, and an edge located in the direction opposite to this corner is movably supported. Each corner located near the diameter line is movably supported on a circumferential rail laid along the radius of a circle constituting the planar circular shape on the entire roof, and each corner located on the opposite side The roof was movably supported by an outer circumferential rail laid along the trajectory of the roof as it pivoted along the circumferential rail.

(Operation, Use) When opening a roof that is circular in plan, the pivoting roofs on the sides closer to the diameter line first pivot in the left and right directions of the diameter line, and at that time, the roofs on the circumferential rails The support point moves along the radius of a circle that forms a planar circle across the entire roof. For this purpose, horizontal guide rails on the fixed roof are laid straight along the diameter line of the roof in order to determine the direction of movement that is dependent on such a pivoting movement.

For this purpose, the support points on the fixed roof of each pivot roof are moved linearly along a diameter line in the direction of the outer circumference of the roof.

Similarly, the point on the outer circumferential side of the roof where the corner part on the side opposite to the diameter line is supported on the outer circumferential rail is the point where one support point of the rotating roof moves on the circumferential rail and is fixed roof. When another support point moves along the upper horizontal guide rail, the locus of movement extends somewhat toward both wings of the roof.

The other pivoting roof, ie the pivoting roof located between the pivoting roof and the fixed roof on the diametric side, performs a similar movement.

Therefore, when the pivoting roof moves on the circumferential rail, the center point accompanying the pivoting movement moves linearly toward the outer circumference of the roof on the horizontal guide rail on the fixed roof, so the opening position of the pivoting roof is They fit eccentrically from the center point of the entire roof and move toward the top of the fixed roof, completely overlapping each other.

In addition, as a result of this, the area where the swirling roof spreads in the direction of both wings of the entire roof and protrudes from the roof does not require the length of the swirling roof to be the radius length of the swirling motion, so it only gradually spreads slightly while drawing a gentle curve. I'm living there.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a dome roof 1 having a circular planar structure, and this dome roof is equipped with an eave-like fixed roof 2 that slightly covers a part of the inner peripheral edge of the circular structure, and the remaining part is located at the center of the fixed roof 2. , and is divided into left and right parts along the diameter line passing through the center point of the dome roof 1, and further divided into left and right parts at the intersection of the tip edge where the fixed roof 2 extends like an eave and the diameter line segment. It is provided with a larger first swing roof 3 located closer to the diameter line and a smaller second swing roof 4 located closer to the fixed roof 2, respectively, in the radial direction.

That is, the first swirling roof 3 and the second swirling roof 4 are arranged symmetrically on both sides of the diameter line.

These roofs have level differences such that the second swinging roof 4 overlaps the fixed roof 2, and the first swinging roof 3 further overlaps the fixed roof 2.

Further, on the surface of the fixed roof 2, a pedestal 5 is installed horizontally along the diameter line of the dome roof 1, and a plurality of horizontal and linear guide rails are provided on the top surface of the pedestal 5. 6
．． 6 is installed.

First pivoting roof 3. Both the second swing roof 4 and the fixed roof 2
The overlying corner portions are movably supported by this guide rail 6, and the first and second pivoting roofs 3 and 4 are also at a level beyond ζ (as explained above, just enough to overlap each other). For this purpose, the first swing roof 3 is supported by a running cart that runs on a guide rail 6 laid on the top surface of the pedestal 5, and the second swing roof 3, which is located at a lower level, is The rotating roof 4 is a side surface of the pedestal 5, and a guide rail 6 is installed at a position slightly lower than the top surface.
It is supported by a.

The plane of such a dome roof 1 is shown in FIGS. 2 and 3, and for convenience of explanation, the guide rails etc. necessary for the pivoting movement when the first pivoting roof 3 and the second pivoting roof 4 open and close are shown in FIGS. Referring to Figure 3, the first swing roof 3
The corner portion where the second swing roof 4 moves along the circumferential direction of the dome roof 1 is movably supported by a circumferential rail 7 laid along the radius of a circle where the dome roof 1 forms a circular plane. The circumferential rail 7 that supports the first rotating roof 3 is located on the outer side with a large radius, and the inner circumferential rail 7a that has a small radius supports the second rotating roof 4. That is, the first pivot roof 3 and the second pivot roof 4
This is because the second swing roof 4 is shorter in length because they are stacked on top of the fixed roof 2 at different levels so as to overlap each other in a laminated structure.

The corner portions of the first pivoting roof 3 and the second pivoting roof 4 supported by the circumferential rail 7.7a are on the side closer to the diameter line of the dome roof 1. That is, when viewed in the figure, it is the outer peripheral end of the dome roof 1 and the right corner thereof. As for the support of the left corner, when the right corner moves along the circumferential rail 7.7a, the radius of the dome roof 1 and the first pivot roof, 3 and the second
Because the lengths of the pivoting roofs 4 of the two pivoting roofs 4 do not match, the corners of the first pivoting roof 3 and the second pivoting roof 4 on the diameter line side are circular curves. When moving along the respective pivoting roof 3.4 guide rail 6
The top of the dome roof 1 is moved linearly toward the outer periphery of the dome roof 1, and an outer peripheral rail 8 is laid along the movement locus of the left end of the swing roof 3.4.

That is, when viewed in the figure, the tip and left end of the swing roof 3.4 is supported by the outer peripheral rail 8.

When the swinging roof 3 and the swinging roof 4 move along the circumferential rail 7 and the guide rail 6, the tips of the swinging roofs 3 and 4 and the corners located on the fixed roof 2 side automatically form a dome. In both wing directions of the roof 1, the shape gradually widens as it approaches the fixed roof 2.

In the above configuration, as shown in FIG. 2, the pivoting roof 3 and the pivoting roof 4 constitute a circular dome roof 1 together with the fixed roof 2, and when opened, the first pivoting roof 3
Alternatively, the second pivoting roof 4 may be pivoted simultaneously or separately asynchronously, and these pivoting roofs 3, 4 first move along the remaining guide rail 6 and the outer periphery with reference to the direction of movement of the circumferential rail 7°7a. When the point supported by the rail 8 is in a driven movement and the first pivoting roof 3 or the second pivoting roof 4 is moved towards the fixed roof 2 by the point supported by the circumferential rail 7.7a. In response to this, the points supported by the guide rails 6 and the outer peripheral rails 8 are also moved toward the fixed roof 2, and are fully opened as shown in FIG. 3.

When it closes, it performs the exact opposite movement. Furthermore, although the guide rail 6 is horizontal, it is recommended that both the circumferential rail 7 and the outer circumferential rail 8 be laid horizontally in order to smooth and facilitate the movement of not only the guide rail 6 but also the pivoting roof 3°4. .

(Effects) As explained in detail above, the retractable roof of the present invention includes an eave-shaped fixed roof that slightly covers a part of the inner circumferential edge of a flat circular roof, and the remaining parts are fixed relative to the fixed roof. The rotating roofs have level differences so that they overlap, and each of these rotating roofs also has a level difference so that it overlaps the fixed roof, and the opening and closing movement is laid along the radius of the circle that makes up the planar circular shape. The center of rotation moves toward the outside of the roof so that it moves straight along the horizontal guide rail laid on the fixed roof, based on the locus of movement of the circumferential rail, which protrudes toward the outer circumference of the roof when the roof opens. At the same time, each swing roof overlaps the fixed roof, making it possible to increase the opening ratio.

Furthermore, since the moving direction of the rotating roofs can be made horizontal, each rotating roof is free from natural falling motion, making it possible to reduce the moving power capacity and at the same time making it easier to ensure safety.
