Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a retractable roof that can be freely erected and removed from, for example, an event venue.

``Conventional technology'' Retractable roofs can satisfy the conflicting demands of providing a sense of openness, sunlight, and fresh air while also eliminating the negative effects of rainy weather, and are already available in various configurations. is provided or proposed.

For example, a roof can be removed from a roof construction site by simply moving it laterally from the intended roof construction site, or a roof can be constructed with a fixed roof section and multiple movable roof sections, and a movable roof The upper part of the area where the roof is to be erected is released by pulling the part onto (inside) the fixed roof part, or the roof is made into a flat plate and is configured to be foldable.
There are some that open or close the area above the construction site by folding or unfolding it.

``Problems to be Solved by the Invention'' However, although the conventional retractable roofs described above certainly achieve the above-mentioned intended purpose, they also have the following drawbacks.

That is, if the roof is removed from the construction site by simply moving it in parallel, valuable space is sacrificed because a relief section is required for the roof to be removed. In addition, in the case where the movable roof section is drawn onto (inside) the fixed roof section, the fixed roof section supports the movable roof section in the closed state, so it is necessary to strengthen the fixed roof section structurally. In addition, the movable roof section is also cantilevered, requiring structural reinforcement, which increases costs.

For this reason, an embankment has been proposed in which the movable roof section is divided into a large number of parts, but this is not necessarily practical as there are problems with the stability of the roof in the closed state and the drive of the movable roof section. moreover,
A foldable type can eliminate the need for an evacuation space, but it requires a new storage section and the like, and the operating mechanism becomes complicated.

"Means for Solving the Problems" Therefore, the present invention has a dome shape that has a circular planar shape as a whole in the closed state and is convex upward,
A roof constructed so as to cover an object to be constructed from above is divided into left and right parts, one of which is a movable roof part and the other is a fixed roof part, and this movable roof part is rotatable about the center of the circular shape. and is formed in a shape that can be superimposed above or below the fixed kojikon part as the movable roof part rotates, and the movable roof part and the fixed roof part are
The above-mentioned problem is solved by configuring a retractable roof that can be freely retreated from the roof construction object when these are superimposed on each other.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

This stadium 1 consists of a roughly circular ground 2, spectator seats 3 provided around the ground 2 (both of which are subject to roof construction), and a retractable roof 4 that covers the entire ground 2 and spectator seats 3. ing.

Figures 1 to 3 show the retractable roof 4 in its closed state, and the roof 4 has a circular planar shape as a whole, and an upwardly convex dome that looks like a spherical object turned upside down. formed into a shape.

This roof 4 is divided into two parts to the left and right from the circular center in plan view, one of which (the left side in FIG. 1) is a movable roof part 5, and the other (the right side in FIG. 1) is a fixed roof part 6. has been done. The fixed roof part 6 has a radius of curvature larger than that of the movable roof part 5 by approximately the thickness of the roof, and therefore the movable roof part 5 is configured to be superimposed below the fixed roof part 6.

The fixed roof section 6 and the movable roof section 5 are supported by a substantially annular support structure 7 provided around the audience seats 3. This support structure 7 includes a semi-annular movable roof support part 8 located below the movable roof part 5 in a closed state, and a semi-annular movable roof support part 8 located below the fixed roof part 6 in one direction away from the end of the audience seats 3. The fixed roof support part 9 has a shape extending from the top to the right.

As shown in FIG. 4, the movable roof support part 8 is formed with an annular orbit IO having a diameter slightly smaller than the semicircle of the movable roof part 5 in plan view. This track 10 consists of a movable roof section 5
It is formed in a groove having a bottom surface 11 in the normal direction at the end thereof and side surfaces 12, 12 rising vertically from above and below the bottom surface 11. On the other hand, at the end of the movable roof section 5, as shown in FIG.
1 and the side surface 12.12, there are running wheels 14,...
・is provided. Thereby, the movable roof portion 5 is configured to be rotatable around the circular center of the roof 4.

As shown in FIGS. 13 and 14, a ball seat 20 is provided at the connecting portion between the movable roof portion 5 and the truck 13, that is, at the support portion of the movable roof portion 5. That is,
As shown in FIGS. 13 and 14, a support member 22 having an upwardly convex hemispherical surface 21 is provided on the upper surface of the truck 13, and a supporting member 22 having an upwardly convex hemispherical surface 21 is provided at the end of the movable roof portion 5. A mounting member 24 having a recess 23 that fits into the surface 21 is provided, and these support member 22 and mounting member 24 are attached to a predetermined M
The spherical seat 20 is configured by being loosely connected with the retaining bolts 25, . . . in a separated state. As a result, the movable roof portion 5 is rotatably supported around the hemispherical surface 21, and even if the force acting on the movable roof portion 5 and its direction change, the spherical seat 20 rotates as appropriate. Smooth movement is possible without applying excessive force to the cart 13. In particular, in this embodiment, as shown in FIG. 14, thrust receiving running wheels 14, .
Very desirable.

On the other hand, the fixed roof support part 9 is formed so that its upper end is lower than the movable roof support part 8, and is formed into a slope that goes downward as it moves away from the audience seats 3. As shown in FIG. 11, a movable cart 15 with a drive mechanism is interposed between the fixed roof support section 9 and the fixed roof section 6, and the movable cart 15 is constructed on the fixed roof support section 9. are placed on the orbits 16, 16, . . .

This movable trolley 15 includes a base 17 provided at the lower end of the fixed roof portion 6, and running wheels provided on the lower surface of this base 17! 8
, . . .

Further, a track 19 is formed on the base 17 at the same position as the track 10 of the movable roof support section 8. Therefore, the movable roof part 5 is moved not only along the track 10 of the movable roof support part 8 but also along the track 19 of the fixed roof support part 9.
It is said to be able to freely rotate around its entire circumference around the circular center.

In addition, as for the operation method of the trolley 13 and the moving trolley 15,
For example, it is sufficient to use well-known means such as an appropriate command given by an operator by remote control, and there is no need to use equivalent special means.

Moreover, the tracks 16 on the fixed roof support part 9,...
It is constructed at both ends of the fixed roof part 6 and at the required position, and is parallel to each other along the extending direction of the fixed roof support part 9.
It has an extended configuration. Therefore, the fixed roof portion 5
and the movable roof portion 6 are in a state where they are superimposed on each other, and the movable trolley 15 is on the track 16160. It is configured such that it can be freely retreated from the audience seats 3 (and the ground 2) by moving along.

In addition, in this embodiment, the movable roof section 5 and the fixed roof section 5
Ribs 5a and 6a are formed along the cut surface. The ribs 5a and 6a are provided to reinforce the cut surfaces of the movable roof section 5 and the fixed roof section 6. especially,
In this embodiment, since the movable roof section 5 is configured to be superimposed below the fixed roof section 6, the movable roof section 5 is The ribs 5a of the fixed roof portion 6 are formed in a shape that projects downward, and the ribs 6a of the fixed roof portion 6 are formed in a shape that projects upward.

Next, the opening and closing action of the retractable roof 3 having the above configuration will be explained.

As shown in FIGS. 1 to 3, the movable roof section 5 is located on the left side of the ground 2, and the fixed roof section 6 is located on the left side of the ground 2.
When the movable roof part 5 and the fixed roof part 6 are located on the right side of the ground 2 and the spectator seats 3,
It covers the upper part and forms one large roof over these grounds 2, etc. As a result, the ground 2 and the spectator seats 3 will be protected from rain and wind, allowing people to fully enjoy the competition and watching the games even in bad weather.

On the other hand, in order to open the retractable roof 4, a command is given by remote control to start moving the cart 13 located at the end of the movable roof section 5. As a result, the trolley 13 is moved to the fixed roof portion 6.
Orbit towards! By moving on θ, the movable roof portion 5 also moves with it, and as a result, the fixed roof portion 6 moves until it is superimposed under the movable roof portion 5. As a result, the movable roof portion 5 opens wide as shown in FIGS. 4 to 6.

Next, with the movable roof section 5 superimposed under the fixed roof section 6, a command is given by remote control to start moving the movable cart 15 located at the end of the fixed roof section 6. As a result, as the movable trolley 15 moves on the track 16 in a direction away from the audience seats 3, the movable roof section 5 and fixed roof section 6 also move along with it. As a result, the seventh
As shown in Figures 9 through 9, most of the roof 4 is wide open, and the ground 2 and audience seats 3 have their roofs removed in this area. As a result, the people inside the audience seats 3 can enjoy the sunlight, breeze, etc. from the open area.

Moreover, in order to change the state from this state to the state shown in FIG. 1, that is, the closed state of the roof, the trolley 13,
The movable cart 15 may be moved in the opposite direction to the above-mentioned direction.

In this manner, according to the retractable roof 4 having the above-described configuration, the movable roof portion 5 is rotated below the fixed roof portion 6, and the movable roof portion 5 and the fixed roof portion 6 are moved to the audience seats 3. By moving the roof in one direction away from the roof, the roof can be opened and closed, and the upper part of the ground 2 and the audience seats 3 can be opened and closed completely freely and easily, and the weather can be handled as desired.

Moreover, in this embodiment, the spherical dome-shaped roof 4 is divided into two halves and one of them is used as the movable roof part 5, so the stability of the roof in the closed state is high, and there are few moving parts. The drive mechanism is also simple. In particular, as in this embodiment, ribs 5a, 6a are provided along the cut surface of each roof portion 5.6.
By providing this, the cut surface can be reinforced, which further contributes to improving the stability of the roof mentioned above.

In addition, by rotating the movable roof section 5, it is superimposed below the fixed roof section 6, and furthermore, these movable roof sections 5
Since the roof is opened by horizontally moving the fixed roof part 6 and the fixed roof part 6 together, the evacuation space for the roof is narrower than, for example, a retractable roof that simply moves the roof in parallel. Reasonable.

In addition, in this example, the spherical dome roof is divided into two parts on the left and right.
The movable roof part 5 and the fixed roof part 6 are divided into parts, and since these roof parts 5 and 6 deform differently in the vertical direction due to temperature changes, etc., the movable roof part 5 and the fixed roof part 6 are separated at the cut part. A slight gap is required between part 6g
For this reason, it may be necessary to devise ways to protect the cut portion from rain.

As an example of such a rain cover, as shown in FIG. 17, a rain gutter 40 is arranged along the cut surface of the movable roof part 5, and a rain gutter 40 is provided at the end to receive rainwater from the rain gutter 40. 41 above and below the orbit lO. It is also preferable to arrange a sealing material such as a rubber plate that protrudes upward along the cut surface of the movable roof section 5 to seal the gap between the movable roof section 5 and the fixed roof section 6. Furthermore, a suitable method is to provide a rubber tube instead of the sealing material and inflate it when the roof is closed.

Note that the details of the retractable roof of the present invention are not limited to the above embodiments, and various modifications are possible.

As an example, in the above embodiment, the ribs 5a and 6a are
．． However, as shown in FIG. 12, they may be provided at multiple positions on the roof portion 5. Of course, it may be provided not only in the direction along the plane but also in the direction perpendicular to the plane (left and right direction in FIG. 2). or,
If reinforcement is not required due to the structure of the roof portion 5.6, the ribs 5a, 6
There is no need to provide a.

Further, the support portion of the movable roof portion 5 is not limited to that of the embodiment described above, and well-known structures can be suitably applied.

- As an example, as shown in FIGS. 15 and 16, a flexible joint 30 using pins having mutually orthogonal rotation axes is preferably mentioned. That is, a support member 31 having a substantially U-shape in side view is provided on the upper surface of the movable trolley 13, and a pin 32 is rotatably supported on the support member 31. On the other hand, the movable roof portion 5 Also at the end of
A support member 33 and pins 34 similar to those of the truck 13 are provided, and the rotation axes of these pins 32 and 34 are perpendicular to each other. And these pins 32.3
4 is loosely fitted into a common connecting member 35. As a result, the movable roof portion 5 is connected to the movable cart 13 via the pins 32.34 and the connecting member 35, and the pins 32.3
The moving roof portion 5 is configured to be pivotally supported on the truck 13 by rotating the connecting member 35 about the movable roof portion 4 . Therefore, even with the support part of this illustrated example, the same effects as those of the previous embodiment can be obtained.

Further, the shapes of the movable roof section 5 and the fixed roof section 6 are also arbitrary, and in the above embodiment, the retractable roof 4 had a shape that was divided into two linearly from the circular center, but if they are hooked, they will look like Of course, it may be formed into a shape having a cut surface forming an arc.

Furthermore, the portion of the support structure that supports the fixed roof portion does not need to be a frame as in the above embodiments, but may be a mere pedestal for supporting rails.

Furthermore, it goes without saying that the fixed roof section is not only configured to be movable using a truck as in the above embodiment, but may also be configured to be movable using an air levitation, crawler type drive mechanism, or the like.

"Effects of the Invention" As explained in detail above, according to the present invention, the roof is formed into a dome shape that has a circular planar shape as a whole in the closed state and is convex upward, so that it covers the roof to be constructed from above. The roof constructed on the roof is divided into left and right parts, one part is made into a movable roof part and the other part is made into a fixed roof part, and this movable roof part is configured to be rotatable about the center of the circle, and the movable roof part The movable roof part and the fixed roof part are formed in a shape that can be superimposed above or below the fixed roof part as the parts rotate, and the movable roof part and the fixed roof part are retreated from the roof construction target in a state where they overlap each other. Since we have constructed a retractable roof that can be moved freely, the stability of the roof in the closed state is higher compared to conventional retractable roofs that have a structure in which the movable roof is divided into many parts, and there are fewer moving parts. Its drive mechanism is also simple. In addition, by rotating the movable roof section, it overlaps the fixed roof section, and by moving the movable roof section and the fixed roof section together horizontally, the roof is opened. Compared to a retractable roof that is configured to move parallel to the roof, the evacuation space for the roof is narrower, making it very rational.
