Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof for use in all-weather buildings suitable for athletic fields, baseball stadiums, and the like.

(Prior Art) In general, all conventional retractable roofs have a laminated structure in which the roofs are stacked in several tiers, and the roofs are slid or run in a sliding manner to open and close most of the building.

For example, by attaching running wheels to the beams that support the roof and allowing the roof members to run on the beams, or by configuring the beams to be telescopic and moving the roof members that open and close as the beams pivot onto a fixed roof. Met.

These movable roofs were designed so that when they were opened, they would be stacked on top of each other to increase the area of the opening. Similarly, in order to increase the area of the opening, it is also being considered to make the retractable roof a folding structure.

Additionally, in order to reduce the moving power capacity, opening and closing are performed in the horizontal direction.

(Problems to be Solved by the Invention) When beams are left at openings in order to stably support a movable roof constituting a retractable roof so that it can be freely opened and closed, there is a drawback that the opening lacks a sense of openness.

Additionally, folding roofs require a more complicated roof structure.
Furthermore, there were also problems with the material and durability of the roof membrane.

The present invention has been 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, to have a simple structure, and to minimize the power capacity for opening and closing movement. The present invention aims to provide a retractable roof that can be opened and closed quickly.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention comprises a crescent-shaped fixed roof that forms part of a dome at one end of an outer wall whose plane is substantially circular. At the other end, there is a triangular rotating roof that is divided into left and right sides along a diameter line that passes through the center point of the outer wall and the center of the outer periphery of the other end, and that serves as one wing of the dome and covers part of the central area. Covers the area from the outer periphery of each rotating roof to the outer wall, and the outer edge follows the circumference of the outer wall, and the rotating roof is attached to a superimposed axis that can rotate freely at the end opposite to the fixed roof side. A movable roof that supports and pivots toward the fixed roof, vertical parallel rails that extend on the fixed roof parallel to the central line that divides the movable roof into left and right, and an elastic means that can change the spring constant. A fan-shaped retractable roof consisting of a support cart such as a power cart that supports the movable roof by running on a movable guide rail laid in the circumferential direction of the outer wall and supporting the movable roof. The vehicle height can be adjusted up and down.

(Function) When the movable roof moves along the guide rail on the outer wall,
The pivoting roof is integrally supported by the movable roof with an overlapping pivot, and uses this pivot point as the pivot point to rotate toward the outer circumference while moving integrally with the movable roof toward the fixed roof. Tsutsu,
The rotating roof and the moving roof move from one end of the outer wall to the other end to an overlapping position on the fixed roof. This forms a wide opening in a part of the top surface surrounded by the outer wall.

When closing the opening, the movable roof returns to its original position, and at the same time, the rotary roof rotates in its original direction, closing the opening of the building with both the movable roof and the movable roof. .

During these opening and closing movements, the power load required to move the roof is reduced by mechanical friction due to the balance between the load received by one power vehicle and the load received by other power vehicles by adjusting the vehicle height of the power vehicle. Receive a significant reduction in losses.

Furthermore, by changing the spring constant of the springing means of each support carriage, the load acting on each support carriage can be adjusted.

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

Fig. 1 shows a hemispherical dome roof 1. This dome roof 1 has a fixed roof 3 that forms part of the dome on an outer wall 2 that stands in a circular plane, and a retractable roof that also forms a dome. The rotary roof 4 and the movable roof 5 are supported.

That is, the fixed roof 3 is formed into a crescent shape with a convex curved surface covering one end of the top space of the outer wall 2, and the outer peripheral edge forming the crescent shape matches the radius of curvature of the outer wall 2. ing. The remaining ceiling space is a rotating roof4. It is covered with a movable roof 5.

As shown in FIG. 2, from the outer periphery (? The rotation points of the rotating roof 4 are set on the left and right sides near the edges, and the outer side of the opening is covered with the movable roof 5, which has a rotation axis 6 at a position corresponding to this rotation point, and the inner side is covered with the above rotation point. It is covered with a rotating roof 4 whose base end is pivotally connected to a shaft 6.

That is, the moving roof 5 and the rotating roof 4 are arranged adjacent to each other with a level difference that allows the rotating roof 4 to overlap the moving roof 5, and are approximately triangular, and the leading edge on the opposite side to the rotating shaft side is the fixed roof. It has a convex curved surface that draws an arc along the inner peripheral edge of the opening, and is located on the left and right sides of a line passing through the center of the opening.

The movable roof 5 is located outside the rotating roof 4 and covers the outside of the opening.

Both the rotating roof 4 and the movable roof 5 have a convex curved shape in the surface direction, and together with the fixed roof 3 constitute the dome roof 1 on the surface of the outer wall 2.

These rotating roofs4. The movable roof 5 is supported by traveling wheels on a guide track so as to be freely movable, and its side view is shown in FIG.

A movable guide rail 7 is laid on the upper surface of the outer wall 2, and a movable guide rail 8 is laid near the inner circumference of the surface of the fixed roof 3. It is supported so that it can run freely on rails 7.8.

In addition, the rotating roof 4 is parallel to the left and right sides of the straight line that bisects the center of the dome roof 1, and the dome roof 1 is connected to the surface of the fixed roof 3.
upper and lower parallel rails 11 extending in the outer radial direction, and a movable roof 5
It is supported by a rotation guide rail 12 laid along the side edge of the fixed roof 3.

Regarding the opening/closing action of the roof, as is clear from FIG. 1, when the dome roof 1 opens from the closed state as shown in the figure, the rotating roof 4 rotates outward about the rotation axis 6, and as shown in FIG. At the same time, the movable roof 5 is pivoted towards the fixed roof 3 along the guiding direction of the movable guide rails 7 on the outer wall 2, ie along the outer circumference of the dome roof 1.

In this way, both the rotating roof 4 and the movable roof 5 move toward the fixed roof 3.

When the dome roof 1 closes, both the rotating roof 4 and the movable roof 5 return to the closed position before opening in a completely reverse order.

In this embodiment, as far as the movable roof 5 is concerned, such opening/closing movement is entrusted to the traction force of the power truck 9.

When the power truck 9 moves on the moving guide rail 7, the movable roof 5 is driven in the circumferential direction of the outer wall 2 together with the intermediate truck 10.

The power truck 9 generally has a configuration as shown in FIG. are connected by a cylindrical upper and lower frame connecting column 17 so that the interval can be adjusted.

The upper surface of the upper frame 13 is provided with a mounting base 18 for mounting and fixing it on the movable roof 5.

Further, an equalizer plate 19 is vertically provided on the back surface of the lower frame 14, and an equalizer triaxial truck 21 having an equalizer shaft 20 is pivotally connected to the equalizer shaft 20.

The equalizer triaxial truck 21 has the top of a trapezoidal plate pivotally connected to the equalizer plate 19 by an equalizer shaft 20, has a wheel attached to one end of the bottom, and has another equalizer shaft 20a at the other end. In addition to the plate 19, an equalizer plate 22 having wheels at both ends of a rectangular shape is pivotally mounted.

This absorbs the swinging motion caused by the movable roof 5 or the movable guide rail 7 side, and improves the stability of support.

Such a configuration is not limited to the power truck 9, but also the intermediate truck 1.
Needless to say, it is also effective for 0.

Further, the coil spring 15 and the shock absorber 16 are sufficient at least only on the power truck 9 side, but the intermediate truck 10
There is no problem in attaching it to Since any one of these may be used, it is provided on the side of the power truck 9 in the embodiment.

Upper frame 13 by changing the length of shock absorber 16
This is to adjust the distance between the lower frame 14 and the lower frame 14.

That is, when the vehicle height is adjusted by changing the level of the upper frame 13 of each power truck 9 located at both ends of the base of the movable roof 5, the power truck 9 supporting these movable roofs 5. The shared load of the movable roof 5 and the like that is shared by the intermediate truck 10 changes.

Furthermore, by changing the spring constant of the coil spring 15 of each truck 9, the load acting on each truck 9 can be adjusted.

Therefore, the vehicle height can be made variable by changing the length of the shock absorber 16 so that the vertical load shared by the power truck 9 is at least lighter than the vertical load shared by the intermediate truck 10. . In this way, the load distribution between the two carts and the intermediate cart 10 is changed, making it possible to reduce the power capacity.

(Effects) As described above in detail, according to the retractable roof of the present invention, the outer wall and the fixed roof support the retractable roof, and no beams are provided on the top surface, resulting in an excellent open feeling.

Furthermore, since the fixed roof is crescent-shaped, the inner peripheral edge of the fixed roof is curved outward to make the opening wider.

Furthermore, since the top surface of the dome is configured such that a rotating roof that opens and closes by rotational motion is stacked on a movable roof, the storage area when opened can be reduced.

At this time, since the vehicle height of the power truck or the support truck such as the intermediate truck can be adjusted up and down, the vertical load of the movable roof can be evenly distributed to each truck.

Furthermore, by changing the spring constant of the springing means of each support carriage, the load acting on each support carriage can be adjusted.

Therefore, compared to the case where a large load is applied only to the power truck, the mechanical motion loss is reduced, and the power can be used efficiently, resulting in the effect that opening and closing can be performed with a relatively small power capacity.
