Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an openable and closable roof having a characteristic in a moving direction such as an openable and closable dome roof.

<< Prior Art >> Conventional open / close type dome roofs include a vertical movement type, a horizontal movement type, and a rotation movement type, depending on the movement means and movement direction of the roof.

In the vertical movement type, the moving roof moves up and down toward the opening. Further, in the horizontally movable type, the movable roof horizontally moves 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 >> The horizontal moving type requires an area for receiving the moving roof in the moving direction, and the vertical moving type tends to be large in terms of moving power capacity. Further, although the rotational movement type is advantageous in these points, the support structure is unstable.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an opening / closing roof in which a supporting structure of a rotary movable roof is stabilized.

<Means for Solving the Problem> In order to achieve the above object, the retractable roof of the present invention is a dome roof having a plane circular shape, and is a crescent moon formed by being surrounded by a chord intersecting a diameter axis of the roof and a peripheral portion. Of the reference roof, and two crescent-shaped moving roofs formed by a ridge and a string that intersects the imaginary diameter axis at each constant plane angle from this diameter axis and one end of the reference roof The movable roof is movably supported with different levels so as to draw an arc along the outer peripheral edge of the dome roof, and the central positions of the peripheral edges of the movable roof and the reference roof are fixed to each other. One end near the outer periphery of the roof member shaped so as to cover the central opening formed when the two are stopped at the interval is pivotally attached to the rear surface of the reference roof, and the peripheral edge portion in the direction opposite to the axial attachment point is provided. Moves along the turning trajectory on the roof Further, it is provided with a rotary roof rotatably supported on the rear surface of the reference roof.

《Action》 The moving roof supports the peripheral edge on the outer wall edge of the dome roof, and the rotating roof is supported by the fixed roof and the moving roof, both of which have good stability. The outer edge moves around the landing point while being supported on the moving roof in the direction of rotation, and fits on the back surface of the reference roof.

Next, the moving roof swivels along the periphery of the outer wall of the dome roof and fits under the reference roof.

 The opposite movement occurs when closing the opening.

Move the standard roof along the outer wall edge,
You may change the accommodation position of a rotating roof.

<Examples> Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the plane of a retractable dome roof with the roof closed, and forms a half-moon shaped reference roof 2 integrally with a circular outer wall 1.

The reference roof 2 is integrated with the outer wall 1 to form a fixed roof, but it may be movably supported by a traveling rail laid on the outer wall 1.

 However, it is fixed in this embodiment.

Near one of the inner angles of the "rice ball" -shaped rotary roof 3 in which each side of the triangle is formed in an arc shape, a rotary shaft 4 is pivotally supported on the rear surface of the reference roof 2 and the rotary shaft 4 is centered. It fits under the reference roof 2 as an axis or is dispatched above the opening.

The movable roofs 5 and 6 which are similar in shape to fit under the reference roof 2 are supported at such a level that they overlap each other, and the supporting carriage 7 of the movable roof 5 is located below the rotating roof 3. The guide rail 8 laid along the outer wall 1 at a certain level position, and the movable roof 6 is laid on the outer wall 1 by the support carriage 7a at a lower level position.
8a is supported to run freely.

The guide rails 8 and 8a extend from the bottom of the reference roof 2 in directions opposite to each other in the left-right direction to a position up to a plane angle of 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 movable roofs 5 and 6 move to the position of 210 degrees around the reference roof 2 with the reference roof 2 as the reference, and the roofs 5 and 6 are overlapped with each other in the vertical direction and overlapped with each other in the center. They are located at 120 degree intervals.

At that time, the rotating roof 3 covers the opening of a regular triangular shape in which the edges corresponding to the respective strings face each other. Therefore, the support rails 9 of the rotating roof 3 are installed on the rear surface of the reference roof 2 and the upper surface of the moving roof 5 along the rotation trajectory of the rotating roof 3. The support rail 9 is directly connected to the back surface of the reference roof 2 along the edge of the rotating shaft 4 in the opposite direction. However, the moving roof 5 is the support rail 9 that travels on the roof surface, and is the same as the reference roof 2. The back side suspends the rotating roof 3.

Of course, the rotary shaft 4 of the rotary roof 3 may be provided on the movable roof 5 as shown in FIG. 3 and moved on the movable roof 5, but since the movable roofs 5 and 6 have steps, In this case, the movable roof 6 is swiveled to the movable roof 5, and the movable roofs 5 and 6 move below the reference roof 2 while supporting the rotating roof.

As described above, in any case, as shown in FIG. 2, the rotating roof 3 first rotates about the rotating shaft 4 on the support rails 9-9a, and then the moving roof 5 moves. , 6 run on the guide rails 8-8a on the support rails 7, 7a along the outer wall 1 and turn. In this way, the opening 10 of the portion excluding the reference roof 2 is obtained on the inner peripheral side of the outer wall 1.

As it is, this reference roof 2 may be slightly moved along the outer wall 1 to be used for shielding of direct sunlight and shielding of strong wind according to the wind direction.

<Effect> As described 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 along the outer wall along the outer peripheral edge thereof. Is supported, and one side that forms the crescent is a string,
Since it does not pass through the center apex, the height is low, and both ends intersect the ends of other roofs, so if you support the center of the periphery and both ends while reducing the surface that receives wind resistance, you can support three points. Therefore, there is an effect of obtaining an extremely stable support structure.
