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 plate must be lifted up to the center of the roof, so that the roof can be reliably opened on a sunny day, and the roof can be reliably opened on a rainy day. If it were made to be able to be closed, there was a problem in that the roof structure, such as the drive mechanism or support mechanism for the roof shingles, would be 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 rings are installed in a radial state from the upper rotating ring to the lower rotating ring between the lower rotating ring that rotates along the inclined guide part and the upper rotating ring provided on the upper part of the column. A movable roof is formed by the cables and the roofing material stretched between the cables.

Then, forming a roof by covering the ceiling with roofing material and opening the roof by opening the ceiling.
It is configured so that the opening and closing of the roof can be done easily and reliably as both the swivel rings turn.

〔Example〕

Hereinafter, the movable roof of the present invention will be explained with reference to illustrated embodiments.

The movable roof 1 includes a lower swing ring 3 that rotates around the facility 8 along an inclined guide section 2;
A column 4 provided near the bottom of the guide portion 2
and an upper swing ring 5 which is rotatably provided at the upper end of the column 4 so as to have a common rotational axis a with the lower swing ring 3, and between the upper swing ring 5 and the lower swing ring 3. , a plurality of cables 6 are stretched in a radial manner from the upper swing ring 5 to the lower swing ring 3, and a roofing material 7 is stretched over a part of the facility 8 between each of 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 the lower rotating ring 3, which will be described later, and a main body portion 10 that protrudes from the main body portion 10 and extends from the lower rotating ring 3. Guide surface 12a for vertical roller 11
It is formed in a circular shape with the guide surface 10a for the horizontal roller 9 as the outer peripheral surface, and is provided on the outer periphery of the competition facility 8 from one end of the competition facility 8 to the other end. Moreover, the competition facility 8 is provided so as to be inclined from the bottom to the top. Note that a rack 13 is provided on the outer peripheral surface of the protrusion 12. (Second
(See FIGS. 3, 3, and 5) The lower swivel ring 3 is composed of a plurality of cable attachment portions 14 and a connecting rod 15 that connects the cable attachment portions 14. The cable attachment part 14 has a cable tension part 16 formed at its upper end, a main body 17 to which connecting rods 15 are pinned at both left and right ends, and a shaft at both ends of the lower end of the main body 17. Horizontal rollers 9' and horizontal rollers 9' for receiving reaction force are pivoted on both ends of the upper end of the main body 17, and vertical rollers 11 and main body 17 are pivoted on both ends of the upper end of the main body 17. Horizontal rollers 9' for reaction force receiving are pivoted on both sides of the lower end, vertical rollers 11 are pivoted on both ends of the upper end of the main body 17, and vertical rollers 11 are pivoted on both ends of the lower end of the main body 17. a vertical reaction force receiving roller 11', and a guide portion 2 that is pivotally attached to the main body 17.
It consists of a sprocket 18 screwed into the rack 13 of the sprocket and a drive motor 19 for the sprocket 18. (See Figures 2 to 6) Furthermore, the upper swing ring 5 is provided with a support that is erected on one end side of the competition facility 8 so that its axis of rotation is at the same inclination as the axis of rotation a of the lower swing ring 3. 4
The rotary support ring 20 is attached to the upper end of the rotary support ring 20. The rotation axes a of the upper and lower rotating rings 5 and 3 are inclined from one end of the facility 8 to the other end. (See Figures 1 and 2) The roofing material 7 is stretched from the rotational axis a of both the swivel rings 5 and 3 to one end of the facility 8, and as the swivel rings 5 and 3 rotate, the roofing material 7 is The structure is such that a roof can be formed by covering the ceiling of the facility, and the roof can be opened by opening the ceiling. It is provided over 1/2 of the outer circumference of the lower swivel ring 3.

In the movable roof 1 having such a configuration,
When changing the roof material 7 from an open state as shown in FIG. 7 to a closed state as shown in FIG. The lower swivel ring 3 is rotated along the guide part 2 by a sprocket 18 meshing with the sprocket 13. (See Fig. 8) Then, by making a half turn, the roofing material 7 is rotated by the rotating ring 3,
5 is closer to one end of the facility 8 than the rotational axis a,
After covering the ceiling of the competition facility 8, the drive motor 19
, and the rotation of the lower swivel ring 3 is stopped and fixed.

In this way, the roof material 7, which is the movable roof 1, covers the ceiling of the competition facility 8 to form a roof.

Conversely, when opening the ceiling, rotate the lower swing ring 3 by half a turn from the state shown in FIG. It suffices if it is on the end side.

Note that the roofing material 7 may be provided with second lower swing rings concentrically on the inner and outer peripheries of the lower swing ring 3, and may be attached to each lower swing ring over 1/3 of the outer periphery.

In this way, 1/2 of the outer circumference of the above-mentioned embodiment
If it is installed over a period of time, when the ceiling is opened, 1/2 of the roofing material 7 will remain.
The remaining roofing material 7 can be overlapped to make it 1/3.

〔Effect of the invention〕

According to this invention, the upper swivel ring and the lower swivel ring move along the inclined guide part.
By making the roofing material installed between both rings that have a common axis of rotation, that is, the roofing material that rotates around the inclined axis of rotation, a movable roof, the roofing material can come to the other end of the facility rather than the axis of rotation. When the roof is formed,
Furthermore, the roof can be opened when the roof material comes closer to one end of the facility than the axis of rotation, and the roof can be formed and opened simply by rotating the vertical swing ring.

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

In addition, compared to conventional systems in which each roof panel is driven individually, the roof can be opened and closed simply by rotating the swivel ring, and the roof can be opened and closed guided by the swivel ring. can be opened and closed all at once smoothly and reliably.
