Description

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

(Prior Art) Generally, all retractable roofs have a laminated structure in which several layers of roofs are stacked, and these are slid or run in a sliding manner to open and close an entrance to a building.

For example, there are methods such as attaching running wheels to the beams that support the roof so that the roof members run on the beams, or making the beams expandable and contractible so that they can be moved to open and close together with the roofing materials.

These movable roofs are designed to overlap each other when opened, thereby increasing the area of the opening.

In addition, some devices are moved horizontally to reduce the moving power capacity, and at the same time, the roof is pivoted horizontally to reduce the storage space, so that the storage position is stacked in several tiers.

Among the prior art described above, there is a rotating roof in which the roof member is made up of several horizontal subsections and overlaps each other in the storage position, in order to move the roof horizontally and reduce the storage space; Some roofs have a pivot point at the top of the roof, and a pivoting roof that rotates around the pivot point to open and close the top of the playground, etc.

(Problem to be Solved by the Invention) However, when a pivoting roof is supported so that it can move freely, the rocking movement of the support point and the deformation and shaking of the roof side will affect the stability of the pivoting roofs and the pivoting roofs that are horizontally adjacent or overlapping. Moreover, since the load of the rotating roof is concentrated at the pivot point of the rotating roof, a reinforcement structure is required.

The present invention has been made in view of the above circumstances, and its purpose is to absorb the swinging motion of a movable roof such as a pivoting roof, and to disperse the load concentrated at the pivot point of the pivoting roof. To provide a retractable roof support device.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof support device of the present invention is supported by a traveling trolley, and is superimposed and laminated on a revolving roof that travels and moves in the circumferential direction of a dome. In the support device for a retractable roof having a pivoting roof whose base is rotatably pivoted to the pivoting roof, the traveling truck is swingable about the guide shaft direction of the traveling truck with respect to the pivoting roof. In addition to being pivoted, the base end of the pivoting roof is supported by a receiving part that allows and supports the pivoting movement of the pivoting roof on the support pedestal of the pivoting roof.

(Function) The rotating roof rotates around the pivot point to partially open and close the top of the building, and at the same time moves integrally with the movement of the rotating roof.

At that time, when the swing roof sways due to the influence of wind or guide rails,
Since the traveling truck and the swinging roof can swing relative to each other around the guide shaft direction of the traveling truck, that is, in the axial direction of the guide rail, there is no lifting of the traveling truck or deformation of the roof.

In addition, the base end of the rotating roof is supported at the reception desk to allow rotation of the roof, and the load of the rotating roof is not only supported by the rotating shaft, but is also distributed to the reception area. The reinforcing structure around the shaft can also be omitted for the shaft portion of the swing roof that supports the shaft.

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

FIG. 1 shows an overview of a retractable roof 1 implementing the present invention,
This retractable roof 1 supports a crescent-shaped fixed roof 3 that is partially constructed on a circular outer peripheral wall 2, and a rotating roof 4 and a pivoting roof 5 that fit on the fixed roof 3. There is.

That is, the top of the building is covered with a fixed roof 3, and the remaining parts are covered with a day shift roof 4 and a swing roof 5.

Passing from the center point on the outer circumferential side of the fixed roof 3 to the center point on the inner circumferential side, proceeding straight through the part not covered by the fixed roof 3, a rotation axis 6 is set on the left and right sides of the surface near the upper edge of the outer circumferential wall 2. A triangular rotating roof 5-5 is raised and extends from the rotation axis 6 to the inner peripheral edge of the fixed roof 3 in a separate left and right direction along the peripheral edge of the outer peripheral wall 2. The top surface near the center of the top of the building sandwiched by -5 constitutes two triangular rotating roofs 4 extending toward the fixed roof 3 with the corner portions pivoted on the rotating shaft 6 as bases.

When the top surface of the building is made open with these rotating roofs 4 and 5, the rotating roofs 4 rotate outward about the rotating shaft 6, and move above the rotating roof 5. overlaps with

Next, the pivoting roof 5 is attached to the outer peripheral wall 2 with the pivoting roof 4 placed on it.
It pivots along the circumferential direction of the roof 3 and fits on the fixed roof 3.

The outer peripheral edge of the swing roof 5 is supported by a guide rail 7 laid on the outer peripheral wall 2 via a traveling truck 8.

Therefore, the swinging roof 5 is pivoted by the carriage 8 running in the direction guided by the guide rails 7.

FIG. 2 shows a device for movably supporting the swing roof 5 and the swing roof 4 of the retractable roof 1 as described above.

There is a running trolley 8 intermittently on the lower periphery of the rotating roof 5.
In particular, there is a rotation shaft 6 near the center of the lower periphery, that is, on the side across the line passing through the center of the building, and this shaft 6 allows the rotation roof 10
Since the load of the roof is concentrated in the vicinity of the rotation axis 6, the strength of the support device in this area is problematic.

A side pressure receiving rail 9 is installed to surround the outside of the traveling bogie 8 in the traveling direction.

Further, on the outer surface of the bogie frame of the traveling bogie 8, wheels 10 are provided horizontally protruding from the side pressure receivers that come into contact with the rails 9.

Furthermore, the base end surface of the rotating roof 4 is finished as a convex curved surface with a radius R around the rotating shaft 6, and a sliding member 11 with low frictional resistance such as Teflon is attached to the outer surface. A reception 12 having a concave curved surface for receiving the sliding member 11 is provided on the pedestal of the traveling truck 8, and the reception 12 receives the load of the rotating roof 4 in a shared manner.

FIG. 3 shows a cross section of the rotating shaft 6 taken in the vertical and diametrical direction, and the cover 13 covering the rail 9 for the side pressure receiver and the wheel 10 for the side pressure buoy stands up almost vertically from the outer circumferential surface side of the outer circumferential wall 2 and extends from the top. The eaves 14 is bent near horizontally toward the inner circumference, and the eaves 14, which slopes from the outer circumferential side of the reception desk 12 toward the outside of the building and whose tip is slightly shaped above the cover 13, covers the outer surface of the traveling trolley 8. The side pressure receiver protects the outside of the wheels 10 and the traveling bogie 8 with the cover 13 and the eaves 14.

In addition, the side pressure receivers are attached to the bogie frame of the wheels 10 and the bogie frame of the traveling bogie 8, respectively. It is provided with a lifting prevention piece 16-16a having a shape.

As a result, in the side pressure receiver, the floating prevention pieces 16-16a of the wheels 10 and the traveling bogie 8 are
15a to keep swinging and floating to the left and right in the direction of the traveling axis within a certain range.

Furthermore, the support pedestal 17 of the traveling truck 8 has a window that supports the truck frame of the traveling truck 8 with a shaft, and has a rotating roof on its upper surface with a bin 18 that is freely swingable in the axial direction of the guide rail 7. I support 5.

That is, the pin 18 is supported horizontally on the surface of the support pedestal 17 in the axial direction of the guide rail 7.
The swing roof 5 is swingably supported by the swing roof 5.

Therefore, the horizontal shaking of the traveling truck 8 and the shaking of the swing roof 5 itself are absorbed by the bin 18, and the behaviors of the roof 5 and the truck 8 do not interfere with each other.

The rotation axis 6 is located above the bottle 18 and is perpendicular to the orientation of the pin 18. And the rotation axis 6
The load on the rotating roof 4 that is received by the sliding member 11 is stopped at the reception 12, and the rotational movement of the rotating roof 4 occurs while the surface of the sliding member 11 slides on the surface of the reception 12. , the base of the roof 4 itself is allowed to rotate in a state in which it is loosely fitted into the receiving part 12.

Therefore, the rate at which the pivot shaft 6 carries the load of the pivot roof 4 toward the pivot roof 5 is considerably reduced.

In addition, the supporting load of the rotating roof 4 itself is not limited to the rotating shaft 6, but most of it is transferred and distributed toward the reception desk 12.
By applying the load over a wide area, stress concentration is prevented.

(Effects) As explained in detail above, according to the retractable roof support device according to the present invention, the pivoting roof that pivots in the circumferential direction of the dome is supported so as to be swingable around its guide axis. As a result, the movements of the traveling trolley and the roof side do not directly interfere with each other, allowing stable opening and closing movement.

The base end of the rotating roof is supported by the reception desk to allow rotational movement, so the load of the rotating roof is slightly distributed to the rotating shaft, and most of the load is carried by the surface area of the rotating shaft. The main load is distributed toward the reception area, which is larger than the surface area, and the main load flows toward the reception area, preventing the rotating roof from deforming at the rotation axis, and simplifying the reinforcement structure. It has the effect of
