Abstract

PURPOSE:To stabilize a support structure by providing a crescent standard roof and two crescent moving roofs, opening or closing the outer peripheral portion on a dome roof, and opening or closing a center opening with a rotary roof. CONSTITUTION:A crescent standard roof 2 and two crescent moving roofs 5 and 6 are provided on a dome roof with a circular plane. Moving roofs 5 and 6 are moved with a level difference so as to drew arcs along the outer wall periphery of the dome roof, and the outer peripheral portion on the dome roof is opened or closed. The center opening on the dome roof is opened or closed by a rotary roof 3 rotatably fitted on the back face of the standard roof 2. The height of moving roofs 5 and 6 is reduced, a three-point support structure is obtained, and stability can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof, such as a retractable dome roof, which has characteristics in the direction of movement.

(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.

(Problems to be Solved by the Invention) Horizontally movable roofs require an area large enough to accommodate the movable roof in the direction of movement, while vertically movable roofs tend to be large in terms of moving power capacity. Further, although the rotationally movable type is advantageous in these respects, the support structure is unstable.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a retractable roof with a stabilized support structure for a rotary movable roof.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention is a dome roof having a circular planar shape, and is formed into a crescent shape surrounded by a chord intersecting the diameter axis and a peripheral edge. standard roof,
two crescent-shaped movable roofs formed by a chord and a peripheral edge that intersect with the imaginary diameter axis at each constant plane angle from the diameter axis, and one end of which intersects with the end of the reference roof;
The movable roof is movably supported at different levels so as to draw an arc along the periphery of the outer wall of the dome roof, and the center positions of the periphery of the movable roof and the reference roof are fixed at fixed intervals from each other. One end of the circular roof member that covers the center opening formed when the roof member is placed is rotatably pivoted on the reference attic surface, and the peripheral edge in the opposite direction of this pivot point is rotatable. It is comprised of a rotating roof that is rotatably supported on the moving roof and on the reference attic surface along a locus.

(Function) The movable roof has its peripheral edge supported on the outer wall edge of the dome roof, and the rotating roof is supported by a fixed roof and a movable roof, both of which have good stability. Centering around the pivot point, its outer periphery moves on the movable roof while being supported in the rotational direction, and settles on the reference attic surface.

Next, the movable roof pivots along the outer wall periphery of the dome roof and fits under the reference roof.

When closing the opening, the movement is the opposite.

The reference roof may be moved along the outer wall periphery to change the accommodation position of each of the moving roofs and the eight rotating roofs.

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

Figure 1 shows the plane of a retractable dome roof with a closed roof.
A half-moon-shaped reference roof 2 is integrally formed with a circular outer wall 1.

Although this reference roof 2 is integrated with the outer wall 1 to form a fixed roof, it may be supported so as to be freely movable by a traveling rail laid on the outer wall 1.

However, in this embodiment, it is fixed.

The vicinity of one of the interior corners of the "rice ball"-shaped rotating roof 3, in which each side of a triangle is formed into an arc shape, is pivoted to the back surface of the reference roof 2 by a rotating shaft 4, and the rotating roof 3 is pivoted around the rotating shaft 4. It can be used as a shaft to fit under the base roof 2, or it can be moved over an opening.

Movable roofs 5 and 6, which are similar in shape to the standard roof 2 and can fit under it, are supported at such a level that they overlap each other, and the support cart 7 of the movable roof 5 is placed under the rotating roof 3. The movable roof 6 is placed on a guide rail 8 laid along the outer wall 1 at a level position, and the movable roof 6 is further supported by a support cart 7a on a guide rail 8a laid on the outer wall 1 at a level position below it so as to be freely movable. are doing.

The guide rails 8.88 extend from below the reference roof 2 in opposite left and right directions to positions up to a plane angle of about 210 degrees from the center of the reference roof 2, and their tips slightly overlap each other.

In this way, when the roof opening is closed, the moving roof 5.6 moves to a position 210 degrees to the left and right with the reference roof 2 as a reference, and the roofs 5 and 6 move to the center while overlapping each other's ends vertically. They are located at 120 degree intervals.

At this time, a rotating roof 3 covers an equilateral triangular opening whose edges corresponding to the respective chords face each other. For this reason, support rails 9 for the rotating roof 3 are installed on the back surface of the reference roof 2 and the upper surface of the movable roof 5 along the rotation locus of the rotating roof 3. The support rail 9 is directly connected to the back surface of the reference roof 2 along the edge in the direction opposite to the rotation axis 4.
On the movable roof 5, there are support rails 9 that run on the roof surface.
The back surface of the reference roof 2 is used to suspend the rotating roof 3.

Of course, the rotating shaft 4 of the rotating roof 3 may be provided on the movable roof 5 as shown in FIG. 3 and moved onto the movable roof 5, but since there is a step between the movable roofs 5 and 6, In this case, the movable roof 6 is pivoted toward the movable roof 5, and is moved below the reference roof 2 while the movable roof 5 and 6 support the movable roof.

In any case, as described above, as shown in FIG. , 6 are support carts 7, 7a that run along the outer wall 1 on guide rails 8-8a and rotate. In this way, an opening 10 is obtained on the inner peripheral side of the outer wall 1 in a portion excluding the reference roof 2.

The reference roof 2 may be slightly moved along the outer wall 1 and used to block direct sunlight or block strong winds depending on the wind direction.

(Effects) As explained in detail above, according to the retractable roof of the present invention, the crescent-shaped reference roof and the other two crescent-shaped movable roofs move their outer edges along the outer wall. Moreover, one side forming the crescent is a chord, and it does not pass through the center apex, so the height is low, and both ends intersect with the ends of other roofs, reducing wind resistance. By supporting the center of the periphery and both ends while reducing the receiving surface, three-point support is achieved, which has the effect of obtaining an extremely stable support structure.
