Description

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

(Prior Art) In general, all conventional retractable roofs have a laminated structure in which the roofs are stacked in several tiers, and the roofs are slid or run in a sliding manner to open and close most of the building.

For example, you can install running wheels on the beams that support the roof and run the roof members over the beams, or you can make the beams expandable and move the roof members that open and close with the beams onto a fixed roof. there were.

These movable roofs were designed so that when they were opened, they would be stacked on top of each other to increase the area of the opening. Similarly, in order to increase the area of the opening, it is also being considered to make the retractable roof a folding structure.

(Problems to be Solved by the Invention) When a beam is left in an opening to stably support a movable roof constituting a retractable roof so that it can be opened and closed, there is a drawback that the opening lacks a sense of openness.

Furthermore, folding roofs tend to have complicated roof structures, and there are also problems with the material and durability of the roof curtains.

The present invention has been made in view of the above circumstances, and its purpose is to provide a retractable roof that has an excellent open feeling without leaving any beams in the opening when the roof is opened, and that has a simple structure. It is something.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention has a crescent-shaped fixed roof at one end of the dome roof whose plane is substantially circular, and the dome at the other end. A triangular rotating movable roof divided into left and right sides by a line passing through the center point of the roof and the center of the outer circumferential edge of the other end, and a triangular movable roof that overlaps with the movable roof and whose outer edge is in contact with the outer circumferential ring of the dome roof. A fan-shaped movable roof is constructed of a movable roof that moves along the fixed roof and a movable roof that moves toward the fixed roof.

(Function) The triangular rotating movable roof overlaps the movable roof while rotating around the pivot point.

The rotating movable roof overlapped with the traveling movable roof in this way, when the traveling movable roof moves along the outer circumferential ring of the dome roof,
moving in the direction of the fixed roof as one, and the rotating roof and the traveling roof located at the other end of the dome roof move to a position where they overlap with the fixed roof located at one end of the dome roof;
In this way, a wide opening is formed in a part of the redome roof.

When closing the opening, the traveling roof first returns to its original position, and then the rotating roof rotates in its original direction, and both the rotating roof and the traveling roof close the opening of the dome roof. The department will be closed.

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

FIG. 1 shows a dome roof 1 having a hemispherical shape, and this dome roof 1 includes a fixed roof 3, a rotatable movable roof 4, and a movable movable roof 5, which are partially constructed on an outer wall 2 that is erected in a circular shape.
We support this.

That is, the fixed roof 3 is formed in a crescent shape so as to cover the top space of the outer wall 2, and the outer peripheral edge forming the crescent shape matches the radius of curvature of the outer wall 2 and covers the top of the outer wall 2. ing. If we pass from the center point on the outer circumferential side of this fixed roof 3 to the center point on the inner circumferential side, proceed in a straight line through the part not covered by the fixed roof 3, and define the position where it hits the upper edge of the outer wall 2 as the rotation point 6. , about 60 from the rotation point 6 toward the outer circumference of the fixed roof 3
A triangular area defined by the intersection of the rays extending at intervals of 100° and the inner circumferential edge of the fixed roof 3 is covered with the rotating movable roof 4, and the outer wall is rotated from both sides of the rotating roof 4 around the rotating point 6. The remaining portion extending in the direction 2 is covered with a traveling roof 5.

As a result, the outer side 2 forms the outer circumferential ring of the dome roof 1,
The top surface is fixed roof 3 and rotating movable roof 4. It is covered with a traveling movable roof 5.

Furthermore, the rotatable roof 4 moves from the pivot point to the fixed roof 3.
It has a triangular shape divided into left and right sides along an axis extending to the center of the outer periphery.

A stopper 7 is provided at the point M, which is on the above-mentioned axis and the outer periphery of the fixed roof 3 and is located above the outer wall 2. A stopper 7 is provided here, and the movable roof 5 is moved along the upper surface of the outer wall 2 from the stopper 7. Rails 8, 8 are laid down to the rotation point 6 so as to pass underneath.

Similarly, from point N, which is on the axis connecting the rotation point 6 and point M, which is at the center of where the stopper 7 is located, and which is an arbitrary position on the fixed roof 3, towards the moving roof 5. A rail 9 is laid with the same curvature as the rail 8.

In this way, the portion of the movable roof 5 located on the contour of the outer wall 2 is supported on the rail 8 by a self-propelled trolley 10 at an arbitrary interval. Further, at a position where the movable roof 5 overlaps the fixed roof 3 and approaches the rotary movable roof 4, it is similarly supported on the rail 9 by a self-propelled cart 10. . Therefore, since the traveling speeds of the truck 10 on the rail 9 side and the truck 10 on the outer wall 2 side are different, it is necessary to appropriately control the respective speeds. Furthermore, rotating wheels 11 and 11 are provided in the parts where the traveling movable roof 5 follows the outline of the outer wall 2 and is close to the pivot point 6, and the movable roof 5 is rotated by the pivot shaft 11.
It is rotatably supported.

That is, one end of the rotatable movable roof 4 is rotatably supported at a rotary axis 11 near the pivot point 6 so as to overlap the traveling movable roof 5, and the edge portion of the fixed roof 3 The part that slightly overlaps the traveling movable roof 5 is supported on the surface of the traveling movable roof 5 by a free traveling trolley 13 on a rail 10 laid along the rotation locus, and the stopper 7 is supported from the rotation point.
The part of the fixed roof 3 on the side closer to the axis passing toward the opening is on the edge of the fixed roof 3 facing toward the opening, and is a rail laid along the rotation locus of the rotatable movable roof 4. 14 is supported in the same way by a trolley 13.

A winch 15 is provided at a position close to the outer wall 2 on the side of the fixed roof 3 of the movable roof 5, and when the winch 15 pulls the truck 13 toward the outer wall 2, the movable roof 4 moves around the pivot shaft 11.
It rotates and moves around , so as to overlap with the moving roof 5. Therefore, the rotating movable roof 4 is the traveling movable roof 5.
In order to make the level positions of the traveling truck 13 that supports the overlapping portion of the moving truck 13 different from that of the traveling truck 13 where the rotatable roof 4 is supported on the fixed roof 3, the level position is different from that of the traveling truck 13 that supports the overlapping portion of the rotating roof 4 on the fixed roof 3. It is shown in the figure below.

Since each of the rotating roofs 4 and the traveling roofs 5 are symmetrical on the axis passing from the rotation point 6 to the stopper 7, one of them is shown in FIG. That is, in any case, the legs of the traveling trolley 13 running on the rail 14 are arranged so that the angle of inclination of the rotatable roof 4 is appropriate, as shown in FIG. The lower part of the edge where the moving roof 5 always overlaps with the rotating roof 4 is slightly extended to the same level as the rail 14, and a short rail at the same level as the rail 14 is attached to this extended part 16. is provided, and the rotating movable roof 4 becomes the traveling movable roof 5.
When completely overlapping the roof, one traveling carriage 13 of the rotatable roof 4 rides on this extended portion 16. On the other hand, the one shown in the same figure (b) is a traveling movable roof 5
At a portion where the traveling movable roof 5 adjoins the rotary movable roof 4 without providing an extending portion 16 on the movable roof 4, the auxiliary wheels 18 carrying the auxiliary rails 17 provided on the back surface of the rotary movable roof 4 are attached to the movable roof 4. 5, and the traveling movable roof 5
A rotary movable roof 4 that overlaps is supported by auxiliary wheels 18, rails 12, and running wheels 13 that run on them.

FIG. 3 shows these fixed roofs 3 and rotating movable roofs 4. A planar dividing line of the traveling roof 5 is shown. In the figure, when the hemispherical dome roof 1 is viewed from above, its planar shape is a circle, and if the center point is O, then the point M, which is between the rotation point and the stopper 7 described earlier, is a circle. The connecting axis passes through the center 0, and on the way, this axis passes through point N, which is approximately in the center of the fixed roof 3, and eight points that intersect with the inner peripheral edge of the fixed roof 3. If we consider the points where this axis and the axis orthogonal at center 0 intersect with the outer wall 2 as point P and point Q, respectively, then when we draw an arc whose radius is the straight line connecting the rotation point 6 and point P, we get This arc passes through point 8 and point Q. That is, when a radius is drawn as a straight line connecting the rotation point 6 and the point P or Q, this arc intersects eight points and defines the inner peripheral edge of the fixed roof 3.

Further, when the intermediate point of PS and the intermediate point of SQ are respectively defined as P and U, a line connecting the rotation axis 6 and the point P and a line segment connecting the rotation axis 6 and the point U are drawn. From point P through rotation point 6 Q
The area within the range connecting the outer ring line of the outer wall 2 reaching the point and the circular arc points P and Q corresponds to the opening portion of the dome roof 1. Also, point P
The curvature of the rail 9 passing from point N to point U is the same as the curvature drawn by the guiding direction of the rail 8 laid on the top of the outer wall 2.

Furthermore, when opening the left rotary movable roof 4, the P
When the point moves to point P, only the portion that was closed by the rotatable roof 4 becomes open. If the portion closed by the rotary movable roof 4 is defined as a primary opening, the portion closed by the traveling movable roof 5 may be referred to as a secondary opening. This also applies to the respective movable roofs 4.5 located on the right side of the axis connecting the pivot points 6 and M points.

By releasing the secondary opening portion, the primary opening portion and the secondary opening portion become open, and when the rotating moving roof 4 is stacked on the traveling moving roof 5, the traveling moving roof 5 The portion from the rotation point to point P moves toward point M while being guided by the rail 8 as it is. That is, when P reaches M, it stops at stopper 7, and at the same time the point P
ends moving toward point N. The direction of this movement is shown in FIGS. 4 to 6.

Since the opening/closing movement is reversible, it is the same whether it is explained from the fully opened state to the closed direction or from the closed state to the fully opened state, and FIG. 4 shows the closed state.
FIG. 6 shows the fully opened state. Therefore, to explain the opening direction from the closed state, the rotatable roof 4 first rotates toward the outside 2 with the rotary shaft 11 as the center point. When fully opened, it is in a state as shown in FIG. 5, and the rotary movable roof 4 cannot be completely folded toward the top of the outer side 2. The reason for this is that when moving the rotary movable roof 4 in the closing direction, it must be moved upward, and the power capacity for closing must be increased. Therefore, once the rotary movable roof 4 is completely superimposed on the traveling movable roof 5, there is no need to move it further toward the outside 2. In this way, from the state where the rotating movable roof 4 overlaps the traveling movable roof 5, the traveling movable roof 5 moves on its own on the rails 8 and 9.
Then, it moves onto the fixed roof 3 along the arc drawn by the outer wall 2.

(Effects of the invention) As explained in detail above, according to the retractable roof of the present invention, the rails are laid on the crescent-shaped fixed roof that covers one end of the circular dome roof, and the rails are laid on the top of the outer wall of the dome roof. Since the movable roof is supported by the movable roof, it is possible to provide a retractable roof with an excellent open feeling without the need for beams installed across the opening. In other words, the movable roof that covers the fan-shaped opening is divided left and right from the center axis of the movable roof, and has a two-tiered structure, each of which forms a triangle when viewed from above. This is because it is supported at three points with the corner as the support point.

Since the movable roof that covers the opening has a stacked structure, the structure of the frame that makes up the movable roof is simpler than that of a folding type, and the curtain members do not suffer from mechanical fatigue due to folding. Easy to last a long time. Furthermore, since the movable roof is a superimposed rotary movable type in which the movable roofs overlap each other and rotate along the outer circumferential ring of the dome roof, there are parts of the movable roof that protrude outside the dome roof. There are no advantages.

Furthermore, the retractable roof of the normal folding rotary movable type normally requires pivoting to each other at the apex of the dome roof, but in the retractable roof of the present invention, each movable roof is entirely on the outer wall and Since the structure is supported on a fixed roof, there is no need to align the movable roof with the center of rotation as in the conventional stacked rotary movable type, and the mechanical balance is achieved by concentrating each other's forces at one point. There is no need to worry about mechanical balance during the construction process.
