Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a large-scale movable roof that is used as the roof of a sports facility such as a baseball field and can be opened during sunny weather.

[Prior art]

Conventionally, this type of movable roof is generally known to have a structure in which the roof is opened and closed by moving straight from the ground toward the center of the roof.

[Problems to be solved by this invention]

However, in such a structure, each roof board must be lifted up to the center of the roof, and if the roof part can be opened reliably in sunny weather and closed in rainy weather, the roof shingles must be lifted up to the center of the roof. There was a problem in that the roof structure, such as the drive mechanism or support mechanism, was complicated.

This invention was devised in view of the above-mentioned circumstances, and its purpose is to provide a movable roof that can be simplified in structure and that can reliably open and close the roof.

[Means for solving problems]

According to the present invention, a plurality of rotary rings are installed in a radial direction from the upper revolving ring to the lower revolving ring between the lower revolving ring that rotates along the inclined guide portion and the upper revolving ring provided on the upper part of the column. A movable roof is formed by each cable and a roof material provided between each cable.

The structure is such that the formation of the roof by covering the ceiling with roofing material and the opening of the roof by opening the ceiling can be performed in accordance with the rotation of both swivel rings, allowing for easy and reliable opening and closing of the roof. It was designed so that it could be done.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

The movable roof 1 is arranged in a radial direction from the upper rotating ring 5 to the lower rotating ring 3 between the lower rotating ring 3 rotating along the inclined guide part 2 and the upper rotating ring 5 provided on the upper part of the support column 4. It is formed of a plurality of cables 6 stretched across the cables 6 and a roof material 7 provided between the cables 6. (See FIGS. 1 and 2) The guide portion 2 includes a main body portion 10 having a guide surface 10a for a horizontal roller 9 of a lower rotating ring 3, which will be described later.
0 and has a protrusion 12 having a guide surface 12a for the vertical roller 11 of the lower rotating ring 3, and is formed in a circular shape with the guide surface 10a for the horizontal roller 9 as the outer peripheral surface, and is suitable for competition facilities. It is provided on the outer periphery of the competition facility 8 so as to be inclined from one end of the competition facility 8 to the other end side, and from the bottom of the competition facility 8 to the top.

Note that a rack 13 is provided on the outer peripheral surface of the protrusion 12 . (See FIGS. 2, 3, and 5) The lower swing ring 3 also includes a plurality of cable attachment portions 14 and a connecting rod 15 that connects each of the cable attachment portions 14. The cable attachment part 14 includes a main body 17 having a cable tensioning part 16 formed at the upper end thereof, and connecting rods 15 pinned to both left and right end parts.
A horizontal roller 9 is pivotally attached to both ends of the lower end of the main body 17, a horizontal reaction force receiving roller 9' is pivoted to both ends of the upper end of the main body 17, and a horizontal roller 9' is pivotally attached to both ends of the upper end of the main body 17. The horizontal roller 9' for reaction force receiving is pivoted on both sides of the vertical roller 11 and the lower end of the main body 17, and the vertical roller 11 and the lower end of the main body 17 are pivoted on both sides of the upper end of the main body 17. It consists of reaction force receiving vertical rollers 11' that are pivoted on both ends, a sprocket 18 that is screwed into the rack 13 of the guide section 2 that is pivoted on the main body 17, and a drive motor 19 for this sprocket 18. There is. (Second
(See Figures to Figure 6) Furthermore, the upper end of the support 4 is erected on one end of the competition facility 8 so that the axis of rotation of the upper swing ring 5 is at the same inclination as the axis of rotation a of the lower swing ring 3. It is attached to a rotation support ring 20 provided in the section. (See FIGS. 1 and 2) The roof material 7 is provided over two of the outer circumferences of the lower swing ring 3.

In the movable roof 1 having such a structure, when changing the roof material 7 from an open state as shown in FIG. 7 to a closed state as shown in FIG. the rack 1 of the guide section 2.
The lower swivel ring 3 is rotated along the guide part 2 by a sprocket 18 meshing with the lower swivel ring 3. (See Fig. 8) When the roofing material 7 has rotated half a turn and is above the rotation axis a of the swing ring 3.5 and covers the ceiling of the competition facility 8, the drive motor 19 is stopped and the lower part swings. ring 3
Stop the rotation and fix it.

In this way, the roof material 7, which is the movable roof 1, is moved to the competition facility 8.
A roof portion is formed to cover the ceiling portion of the roof.

Conversely, when opening the ceiling, rotate the lower swing ring 3 by half a turn as described above from the state shown in FIG. You should do it.

In addition, the roof material 7 may be provided with a second lower swing ring concentrically on the inner and outer peripheries of the lower swing ring 3, and may be attached to each lower swing ring over 173 of the outer periphery.

In this way, when the roofing material 7 is installed over 2 of the outer circumference of the above-mentioned embodiment, when the ceiling is opened, the roofing material 7 remains over the 2nd region, but when the remaining roofing material 7 is overlapped, only 1/3 of the roofing material 7 remains. can do.

〔Effect of the invention〕

According to the invention, a roof material provided between an upper pivot ring and a lower pivot ring that moves along an inclined guide part;
In other words, by making the roofing material that rotates around the tilted axis of rotation into a movable roof, the roof can be formed when the roofing material comes above the rotational axis, and the roof can be opened when it comes below the rotational axis. The roof can be formed and opened simply by rotating the ring.

Therefore, compared to the conventional structure in which multiple roof panels are hoisted to the center of the roof, a movable roof with a simple structure with fewer parts because there is no need for a drive mechanism or support mechanism for each roof panel. I can do it.

In addition, compared to the conventional system in which each roof panel is driven individually, the rotary support ring only requires the rotation ring to rotate.

The roof can be opened and closed with easy operation, and since the roof can be opened and closed guided by the swivel ring, the roof can be opened and closed at once smoothly and reliably.
