Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof for an all-weather building suitable for an athletic field, a baseball field, and the like.

<< Conventional Technology >> Generally, all the conventional openable roofs have a laminated structure in which roofs are stacked in several stages, and these are slid or run in a sliding manner to open and close the top of a building.

For example, means for moving the beam supporting the roof with a roof member equipped with traveling wheels, or a beam that is configured to be expandable and contractable, and moved and opened / closed together with the roof member.

These have a laminated structure or a folding structure so that when the movable roof is opened, they overlap each other to widen the area of the opening and reduce the storage area.

<Problems to be solved by the invention> Since the movable roof that constitutes the openable roof needs to be stably supported so that it can be freely opened and closed, there is a drawback in that when the beam is left in the opening, the opening feels insufficient. It was

In addition, the structure of the foldable roof tends to be complicated, and there is a problem with the material and durability of the roof curtain.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a retractable roof having a high opening ratio with a minimum opening area when the roof is opened and the beam does not remain in the opening portion. The purpose is to provide a retractable roof that can be stored efficiently in the.

<< Means for Solving the Problems >> In order to achieve the above object, the retractable roof of the present invention is:
A crescent-shaped fixed roof is constructed at one end of the outer peripheral wall that stands up in a substantially circular shape, and a central line segment that passes from the center of the inner peripheral edge of the fixed roof to the other end of the outer peripheral wall through almost the center point of the outer peripheral wall. To the left and right of the line segment, and radial line segments extending at a constant angle toward the inner peripheral edge of the fixed roof from the position between the other end of the outer peripheral wall of the line segment and the center point and the center A triangular rotating roof having two sides as part of the line segment and being in contact with the inner peripheral edge of the fixed roof and having one side curved according to the curvature is arranged, and the rotating roof has the above-mentioned structure. The outside located symmetrically with respect to the center line segment is covered with a moving roof, and for the rotating roof, the corner portion on the starting point side which is in contact with the center line segment and the moving roof is attached to the moving roof by a rotation axis. The movable roof is rotatably pivotally supported, and the other movable roof is supported by a trolley or the like so as to swing along the outer peripheral wall toward the fixed roof. Than it was.

<Operation> The rotating roof is superposed on the moving roof while rotating around a rotating shaft pivotally attached to the moving roof as a central axis.

Thus, when the movable roof moves along the outer peripheral wall, the rotating roof that overlaps the movable roof moves integrally toward the fixed roof and overlaps the fixed roof.

At that time, the corner portion where the pivot point is set as the axis of rotation of the rotating roof is not located near the outer peripheral wall where the central line segment intersects the outer peripheral wall, but instead of the outer peripheral wall and the arena surrounded by the outer peripheral wall. By setting it at a position between the center point and configuring one side of the rotating roof to be short, the structure of the rotating roof itself becomes relatively small,
While the load required for the pivotal movement and the reinforcement structure are lightened, the upper part of the inner peripheral surface that contacts the inner side of the outer peripheral wall has no contact with the rotating roof, but has more contact with the moving roof.

However, the opening ratio of the arena is substantially the same as when the rotating roof with a long side extending to the part where the corner of the rotating roof where the rotating shaft is installed contacts the outer wall is opened. .

<Example> Hereinafter, a preferred example of the present invention will be described in detail with reference to the drawings.

Each of the figures shows the openable roof 1 of the present invention, and sequentially shows the opening and closing movements thereof.

This openable and closable roof 1 has a crescent-shaped fixed roof 3 partially formed at an upper end of a circular outer peripheral wall 2, and a movable roof 4 covering the remaining inner peripheral surface of the outer peripheral wall. It comprises a rotating roof 5 in which one corner portion is pivotally mounted.

The rotating roof 5 has a triangular shape symmetrical to the left and right of a central dividing line segment 6 that intersects with the outer peripheral wall 2 from the center position of the inner peripheral edge of the fixed roof 3 through the center point of the outer peripheral wall 2, and one side that should be called the tip is It is formed on a curved surface along the curve formed by the inner peripheral edge of the fixed roof 3, and the pivot corners, which should also be called the bases, of the outer peripheral wall 2 and the arena surrounded by the outer peripheral wall 2 along the dividing line segment 6. At a position between the center point and the starting point, sandwich the side defined by a line segment that extends radially to a quarter of the inner peripheral edge of the fixed roof 3 and the dividing line segment 6 above. That is, the corners are pivotally attached to the movable roof 4 that covers the remaining top surface of the arena by the rotary roof 5 by a rotary shaft 7.

The rotating roofs 5 are provided with a certain level difference so as to be superposed on the movable roof 4, and the movable roof 4 supports the outer peripheral edge portion of the movable roof 4 on the outer peripheral wall 2 by a carriage so that the movable roof 4 can travel freely. The position of contact with the fixed roof 3 at the inner peripheral edge is supported via a traveling carriage on a guide track 8 laid along the trajectory of the movable roof 4 turning on the surface of the fixed roof 3. The rotating roof 5 is rotated on the movable roof 4 about a rotating shaft 7.

That is, as shown in FIG. 2, each of the rotary roofs 5-5 is pivotally moved about the rotary shaft 7 so as to be divided to the left and right of the dividing line segment 6 and completely overlaps the movable roof 4.

Next, as shown in FIG. 3, the movable roof 4-4 is rotated by the rotary roof 5.
It is swung along the outer peripheral wall 2 toward the fixed roof 3 while overlapping with the above.

When the retractable roof 1 is closed, as shown in FIG. 3, the movable roof 4 and the rotary roof 5 return to their original positions in the completely reverse order from when the movable roof 4 and the rotary roof 5 are opened from the overlapping state.

<Effect> As described above in detail, according to the retractable roof of the present invention, a crescent-shaped fixed roof is formed at one end of the outer peripheral wall which is erected in a circular shape, and the inner side of which is concavely curved. The roof area that fixedly covers the top surface is reduced by the amount of the peripheral edge, and the fixed roof and the outer peripheral wall support a moving roof that swivels along the outer peripheral wall from the opening top surface side to the fixed roof. Since there is no beam at the top of the opening and the swivel movement is in the horizontal direction, not in the vertical direction, the moving power capacity of the moving power mechanism can be reduced.

Further, since the movement reaction force also becomes small, it is advantageous in terms of structural reinforcement.

Furthermore, the starting point of the line segment that forms the rotating roof is set so that the corners of the rotating roof where the rotating roof overlaps the movable roof and the fixed roof are closer to the center from the inner peripheral surface of the outer peripheral wall. Is located between the outer peripheral wall side and the center point, the size of the revolving roof itself becomes relatively small, and in the case of a dome roof where the revolving roof and the moving roof have a three-dimensional convex curved surface. In particular, it is advantageous in terms of the power mechanism because the rotational movement direction of the rotating roof moves up and down.
