Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof for constructing an all-weather stadium or the like using a retractable roof.

(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 for retractable roofs in order to create a sense of openness that is one with nature on sunny days.

For example, a movable roof has a multi-tiered structure, and as the roof moves to open, the storage state becomes a stacked type, making it a challenge to reduce the storage space and increase the open area ratio.

(Problems to be Solved by the Invention) In order to reduce the moving power capacity of the moving roof, it is desirable that the moving direction be horizontal. In order to reduce the storage area when moving the roof, it is advantageous to use a laminated structure.However, from the perspective of reducing the weight of the moving roof itself, it is better to use a dome-shaped roof structure rather than a horizontal roof structure. It's advantageous.

The present invention has been made in view of the above circumstances, and its purpose is to reduce the moving power capacity by reducing the weight and to provide a concrete structure of a retractable roof having a sufficient opening ratio. .

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention is provided with a crescent-shaped fixed roof at one end of an outer peripheral wall whose plane is approximately circular, and an inner peripheral edge of the fixed roof. Rotating rotating wheels arranged symmetrically to the left and right of a dividing line that passes from the center through approximately the center point of the outer peripheral wall and exiting in the outer radial direction, and on both sides near the intersection of the dividing line and the outer wall. A plurality of points are defined radially from near the rotation point to the inner circumferential edge of the fixed roof, and the outermost circumferential side of the roof, which has a stepped structure with level differences, is rotated along the outer wall. The rotating roof has a rotating roof, and the inner side thereof is a rotating roof that rotates outward using the rotating shaft as a pivot point, the rotating roofs overlap each other and are supported by wheels on the rotating roof, and the rotating roof The roof and the wheels that support the corners of the inner end of the pivoting roof on the side opposite to the rotation axis are rotatably supported at positions offset from the support points of the roof.

(Function) When opening, the pivoting roof rotates left and right across the dividing line, and overlaps with the outermost pivoting roof. The pivoting roof and the pivoting roof then pivot together toward the fixed roof.

These opening movements operate in reverse order when switching to closing movements.

When transitioning from rotating motion to swinging motion, the rotating roof is partially supported on the rotating roof by wheels, and the wheels that support the corner of the inner end on the side opposite to the rotating shaft are supported at the support point on the rotating roof. The deflected position rotates in the turning movement direction, changes direction, and moves in the turning direction. This follows the change in the direction of movement when switching between rotational movement and rotational movement.

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

A part of the top surface inside the outer wall 1, which is formed in a circular plane, is covered with a crescent-shaped fixed roof 2, and the remaining outer wall 1 is shown in plan view in Figure 1.
The inner top surface is covered with a rotating roof 3 and a rotating roof 4 in a dome shape.

The rotating roof 3 and the rotating roof 4 are configured symmetrically on both sides of a dividing line 5 extending from the center of the inner peripheral edge of the fixed roof 2 through the center point of the outer wall 1 in the outer radial direction.

That is, from the intersection of the dividing line 5 and the outer wall 1 toward the inner circumferential surface of the fixed roof 2, it is divided along three radial dividing lines at equal angles on each side, with the dividing line 5 as the center line. It has a symmetrical shape, with the outermost part of the three left and right roof members shaped like a bamboo tree cut in half from the center as the pivoting roof 4, and the two inner members serving as the pivoting roofs 3 and 3a.

The pivoting roofs 3 and 3a are rotatable on pivot shafts 6 fixed to the pivoting roof 4 on the left and right near the intersection of the dividing line 5 and the outer wall 1,
Moreover, they are arranged on the swing roof 4 in a laminated manner with different levels.

In addition, the rotating roof 3, 3a and the rotating roof 4 have a retractable roof 7.
In order to construct a the side away from line 5) and the corner position of the inner end (
A wheel is provided on the side closer to the parting line 5), and the rotation guide rail that guides the wheel is laid on the inner end of the fixed roof 2, and the inner end of the wheel Self-propelled carts 9, 9a provided at corner positions run on rotation guide rails 8 to drive the surrounding roofs 3, 3a.

On the other hand, the wheels located at the corner positions on the outer end side of the rotating roofs 3, 3a are slave vehicles 10, 10a.

This follower truck 10.10a runs on the surfaces of the adjacent rotating roof 3a and rotating roof 4.

Furthermore, the outer peripheral side of the swing roof 2 is supported by a power truck 12 at least two points near the rotation axis 6 and near the fixed roof 2 on the swing guide rail 11 laid on the upper end surface of the outer wall 1, and fixed. The inner end in contact with the roof 2 is supported by a truck 14 on a turning auxiliary rail 13 laid on the surface of the fixed roof 2 with the same concentric radius of curvature as the outer wall 1.

When opening, first of all, the self-propelled cart 9 of the rotating roof 3, 3a runs on the rotation guide rail 8 toward the outer circumference of the dome and rotates around the rotation axis 6.

Gradually, the pivoting roofs 3 and 3a fit on top of the pivoting roof 4, respectively.

Then, the pivoting roof 4 is attached to the pivoting guide rail 11. together with each pivoting roof 3, 3a. It is moved on an auxiliary rail 12 by a power truck 12, and is housed on the fixed roof 2 by turning along the outer wall 1.

The fully opened state is shown in FIG. 2. The rotating roofs 3, 3a and the rotating roof 4, which overlap each other, form a "C" shape and stop moving toward the outer peripheral surface of the fixed roof 4, and the end on the rotating shaft 6 side is slightly moved toward the outside of the opening surface. However, the arena part has an aperture ratio of almost 100%.

Note that the rotational movement of the rotating roofs 3, 3a may be carried out by pulling with a wire instead of using the self-propelled cart 9, or by using the rotation guide rail 8 itself as a rack and configuring a binion on the cart 9.
In particular, when using the rack and binion, it is advantageous in that it is easier to obtain a large moving torque and can be used as a negative brake, whereas the rack and pinion must resist the gravity due to the tilt angle peculiar to the dome.

FIG. 3 shows a cross section of the retractable roof 7 when it is fully opened as described above.

The bundle 15 on eight plates that connects the self-propelled carts 9.9a of the rotating roofs 3, 3a to the roof body has a height that maintains a predetermined level of each roof, and the self-propelled carts 9, 9a rotate. Guide rail 8
The rail 8 bears the load when the vehicle travels.

Then, when transitioning from rotational motion to rotational motion, the moving direction of self-propelled cart 9 switches to a direction intersecting the axial direction of rotational guide rail 8, so that rotating roof 3° 3a opens during the process. At the position where the rotational movement is completed, the bundle 15-15 of the self-propelled carts 9, 9a is deviated from the core of the cart, and the roof 3, 3a is
The self-propelled carts 9, 9a are rotatably attached to a shaft so that the direction of the self-propelled carts 9, 9a can be changed.

In this case, when the self-propelled cart 9, rack, or pinion mechanism performs a rotational movement, an auxiliary device is required to help restart the rotational movement from the completed position in the opening process.

Further, at this time, bracket carts 16a, 16 are protruded from the front sides near the center of the rotating roof 4 and the rotating roof 3a, and the rotating roof 3a is located in the upper layer of each.

The back surface of the rotating roof 3 is supported by bracket carts 16a, 16.

The power truck 12 that drives the swinging roof 4 to swing has the following outline. First, the frame end of the swinging roof 4 is connected to a hollow framework 17.

The frame 17 has a right-angled side triangle, and the frame of the swing roof 4 is connected to the oblique side thereof, and the power truck 12 is connected to the bottom of the frame 17, and its power mechanism is housed within the frame 17.

Further, the truck 14 is provided with a floating prevention piece 19 that is engaged with the back surface of the flange of the swing auxiliary rail 13, thereby suppressing the vertical movement of the swing roof 4.

As the details of the trolley 14 are shown in FIG. 4, the turning auxiliary rail 1
3 has two rails with an I-shaped cross section laid close to each other in parallel, a flange 20 for preventing wheels from coming off is located between them, and an axle with wheels running on the rails is provided on both sides of the flange 2o. The eight plates 21 of the cart 14 are formed into concave curved surfaces.

On the other hand, a curved plate 2 having a convex curved surface matching the curvature of the eight plates 21
2 to the 8 plate 21, and after applying sufficient grease to the overlapping surfaces, fix the center pin 23, which passes through the center of the curved plate 22 from the back of the 8 plate 21, and then passes through the frame of the swing roof 4, with a nut. are doing.

The curved plate 22 is fixed to the swing roof 4 for the purpose of absorbing the vertical vibration of the truck 14 by utilizing the curved surface of the curved board 22 and for the purpose of facilitating rotation, and the center pin 23 is not fixed to the swing roof 4. If it passes through the eight plates 21 and the curved plate 22,
A coil spring 24 is compressed on the back side of the curved plate 22, and the center pin 23 is pulled up by the coil spring 24.
The plate 21 and the curved plate 22 are brought into close contact.

Therefore, when a force that exceeds the repulsive force of the spring 24 acts, for example, when a force that lifts the swing roof 4 acts, the spring 24 momentarily stretches and releases the force, preventing the truck 14 from separating from the rail 13. do.

Further, the eight plates 21 and the curved plate 22 are rotatable around the center bin 23, and rotate following changes in the dome curve formed by the fixed roof 2.

(Effects) As explained in detail above, according to the retractable roof of the present invention, a part of the arena top surface is covered with a crescent-shaped fixed roof,
The top surface part that becomes the other opening is a partition that extends radially toward the fixed roof from the vicinity where the outer wall intersects with the dividing line that passes from the center of the inner circumferential surface of the fixed roof to approximately the center of the outer circumferential wall and exits in the outer radial direction. Since it is covered with multiple rotating roofs defined along a line, the planar area of each rotating roof itself becomes smaller,
Can be easily configured.

Therefore, there is an advantage that the power for movement and the reinforcing structure can be made small and simple.

In addition, the outermost circumferential side covered by the rotating roof is a rotating roof that rotates along the outer wall, and it has a laminated structure together with the rotating roofs, so when opened, they overlap each other and fit together, taking up less space. The area is extremely small, and the overlapping area is small, in addition to the fact that it is constructed by finely dividing it in the radial direction, so the aperture ratio is reflectively large. This has the advantage that the aperture ratio is extremely large.

Furthermore, since the rotating roof and the wheels supporting the corner of the inner end of the rotating roof on the return shaft side are rotatably supported at positions offset from the support point of the roof, rotational movement is prevented. This is to cope with the point where the direction of movement changes when the rotating roofs overlap each other.
