Abstract

PURPOSE:To stabilize the supporting structure of a movable roof by supporting a crescent fixed roof and the other two crescent movable roofs, so that the outer circumference thereof can be moved along the periphery of the dome roof. CONSTITUTION:The circumference of a roof surface surrounded by an outside wall 1 is covered by four crescent roofs consisting of fixed roof 2 and movable roof 6, 7, 8. And the opening at the central part is closed by a square parallel motion roof 12. The parallel motion roof 12 is supported by casters 15 arranged on the two rails 13 on the fixed roof, and on the rails 14 laid on the respective surfaces of the movable roofs 6, 8. When the roof is opened, the parallel motion roof 12 is moved on the fixed roof, and then respective movable roofs 6, 7, 8 are successively moved under the fixed roof 2. Thus, the roof can be quickly opened.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof characterized by the shape and combination of movable roofs constituting the retractable dome roof.

(Prior Art) Conventional retractable dome roofs include vertically movable, horizontally movable, and rotationally movable types depending on the means of moving the roof and the direction of movement.

In the vertically movable type, the movable roof moves up and down toward the opening. Further, in the horizontally movable type, the movable roof moves horizontally to open and close the opening, and in the rotary movable type, the movable roof rotates around the opening to open the opening.

(Problem to be solved by the invention) Horizontally movable types require an area large enough to accommodate the movable roof in the direction of movement, and vertically movable types tend to have a large moving power capacity. The mobile type has advantages in these respects, but the support structure is unstable.

In view of the above circumstances, an object of the present invention is to provide a retractable roof that stabilizes the support structure of a movable roof and has a high opening ratio.

<Means for Solving the Problems> In order to achieve the above object, the retractable roof of the present invention has a retractable dome roof having a planar circular shape, and has a step at the periphery of the retractable dome roof. Constructs two crescent-shaped roofs, one of which is a fixed roof, and the other three are sequentially stacked with level differences and can pivot along the periphery under the fixed roof. a movable roof, and a square opening formed in the center is closed by a movable roof that is movably supported on guide tracks laid along at least two parallel axes passing from the movable roof to the fixed roof. It will become.

(Function) The crescent-shaped movable roof has its periphery supported on the periphery of the dome roof, and the parallel movable roof is supported by two or more parallel guide tracks connected to the crescent-shaped movable roof and the fixed roof. Both have good stability, and first the translating roof moves onto the fixed roof.

At that time, the center of gravity of the translational roof shifts to the fixed roof, and the entire translational roof is supported by the track on the fixed roof, that is, by the fixed roof. Therefore, at this time, the support of the parallel moving roof by the track laid on the crescent-shaped moving roof may be released.

The top and middle tiers of the next three remaining crescent-shaped moving roofs,
The one located at the lowest stage is pivoted and moved below the fixed roof along the peripheral edge locus of the dome roof.

Since the peripheral edge of each of these is supported by the peripheral edge of the dome roof, they can be rotated at the same time to quickly open the roof.

The movement is reversed when closing the opening in the dome roof.

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

Figure 1 shows four crescent-shaped roofs in the closed position, with a half-moon-shaped fixed roof 2 integral with the circular outer wall 1 on the left side, and chords extending over the outer wall 1 on the top, bottom, and right sides. A crescent-shaped movable roof 7, 8.9 defined by beams 3, 4.5 is arranged.

The upper edge of the outer wall 1 has level differences that are lowered in stages from the outer diameter to the inner diameter in three steps: top, middle, and bottom, and the beam 3 that constitutes the upper movable roof 6 in Fig. 1 is the lowest. The beam 4 on the right side is passed to the middle tier, the beam 5 on the lower side is passed to the lower tier, and the upper tier movable roof 6. Middle moving roof7. A lower movable roof 8 is formed.

In addition, the outer peripheral edges of these movable roofs 6.7.8 are attached to the upper edge of the outer wall 1, and the rails 9 of the movable roof 6 are attached to the upper tier, the rails 10 of the movable roof 7 are attached to the middle tier, and the rails 10 of the movable roof 7 are attached to the lower tier. 8 rails 11 are laid and supported so that it can run freely. That is, each crescent-shaped movable roof 6, 7.8 is supported by the beams 3, 4.5 and rails 9, 10.11.

With the above configuration, the top surface surrounded by the outer wall 1 is covered with four crescent-shaped roofs consisting of the fixed roof 2 and the movable roofs 6, 7.8, but there is a square opening in the center. remain. As shown in FIG. 2, this opening is closed by a rectangular parallel moving roof 12.

The parallel moving roof 12 is a parallel moving roof 1 on the surface of the fixed roof 2.
Two fixed roof rails 13 are passed in parallel with an interval close to the width of 2, and rails 14 are laid on each surface of the upper movable roof 6 and the lower movable roof 6 along the extension axis of the rails 13. It is supported by carts 15 placed at the right end of each.

That is, the parallel moving roof 12 has its four corners connected to each trolley 15-
It is stably supported by 15-15-15.

In addition, a parallel moving roof 1 is attached to the edge of the fixed roof 2 that becomes the chord.
A roller 16 is protruded to support the back side of the roof 2, and when the parallel moving roof 12 has completely moved above the fixed roof 2, it supports the right edge of the parallel moving roof 12 and moves the rail 14 on the moving roof 6, 8.
The trolleys 1.5.15 mounted on the rails 14 can be released from the rails 14. This is because the shape of the entire roof is dome-shaped, and the more the parallel moving roof 12 moves toward the fixed roof 2, the more the carts 15 and 15 on the moving roofs 6 and 8 rise from the rails 14, so it will almost naturally be in the released state. Become. The stability of the parallel moving roof 12 accompanying this is ensured by the rollers 16.

When opening the roof, the parallel moving roof 12 is first moved onto the fixed roof, and then each moving roof 6, 7° 8 is moved sequentially or simultaneously, or from any fixed roof to the fixed roof according to the convenience of sunlight etc. or the convenience of the event. Rails 9, 10 below 2.
11 to move. In this way, an opening 17 is obtained on the top surface of the outer wall 1 as shown in FIG.

When closing the opening 17, the opening/closing operation procedure is completely reversed.

(Effects) As explained in detail above, according to the retractable roof of the present invention, the crescent-shaped fixed roof and the other two crescent-shaped movable roofs have their outer peripheries aligned with the periphery of the dome roof. It is supported so that it can move along the moon, and one side that forms the crescent moon is a string, and the string does not pass through the center vertex, so it is low in height.
And since both ends intersect with the ends of other Wlls,
This has the effect of providing an extremely stable support structure while reducing the surface that receives wind resistance.

In addition, the chords of these crescent-shaped roofs are four chords that are stepped on the periphery of the dome roof and passed over the parallel girder, so the crescent-shaped movable roof has a short axis extending to the center of extremely thin curvature. Therefore, not only is the structure stabilized by supporting only the periphery, but the aperture ratio is also increased, and since each movable roof has a curved shape, it has a favorable acoustic effect in terms of equalizing the sound pressure level.
