Description

Description: TECHNICAL FIELD The present invention relates to a movable roof for covering a facility for performing sports, events, and the like.

[Related Art] Facilities for performing sports, events, and the like mainly include outdoor facilities and indoor facilities. In the case of outdoor facilities, comfort can be obtained in a mild climate, but on the other hand, there are inconveniences such as the event being canceled due to rainfall or snowfall. On the other hand, in the case of indoor facilities, events can be held irrespective of weather conditions, but on the other hand, there is a drawback of lack of openness.

Therefore, in order to take in only the advantages of the outdoor facility and the indoor facility, it has been considered to cover the facility surface with a movable roof. As shown in FIG. 5, an example of a conventionally considered movable roof is a roof block 1a obtained by dividing a roof body 1 formed in a hemispherical or semi-cylindrical shape into a plurality of parts in the circumferential direction (two parts in this example). , 1b, and these roof blocks 1a,
By rotating the roof 1b about the arc center 2 of the roof 1 as a fulcrum, the roof 1b can be stored in a storage space 3 provided in the basement (Japanese Patent Laid-Open No. 58-176336).

[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional movable roof, since the storage space 3 for storing the roof blocks 1a and 1b must be provided in the ground, the construction work becomes large. In particular, when the facility is a large structure such as a stadium where a sports competition is performed, a great deal of labor and cost are required.

Therefore, an object of the present invention is to provide a movable roof that can open and close a roof block without requiring a storage space in the ground.

Means for Solving the Problems In order to achieve the above object, according to the present invention, a mountain-shaped guide rail is installed on each of front and rear portions of a facility surface, and an even number of roofs are provided between the front and rear guide rails. The two roofs formed by sequentially connecting the blocks so as to be freely foldable by hinges are distributed and arranged at the top of the mountain shape, and are folded along the guide rails from the lower end as a base point so as to be expandable. A support frame that straddles a guide rail from above and below at the end of each lower hinge excluding the position, a pinion gear supported by the support frame and meshed with a rack engraved on the upper and lower surfaces of the guide rail, An opening / closing drive device including a motor for driving the pinion gear is provided, and the hinge portions at the respective folding positions are covered with a flexible waterproof sheet. Configuration.

[Operation] When the roof is extended and closed, the facility surface can be used as an indoor facility. On the other hand, when the roof is folded, the facility surface can be used as an outdoor facility. At this time, the roof body is folded or expanded from the lower end as a base point, and the folded state is a retracted state, but each hinge on the lower side is individually equipped with a rack and pinion type opening / closing drive device. Therefore, fine adjustment of the opening / closing speed and the interval of the lower hinge can be easily performed.

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

FIG. 1 shows an embodiment of the present invention. In order to cover the space above a facility surface 4 such as a sports facility so that the space can be opened and closed, FIG.
A guide rail 5 formed in a triangular mountain shape by right and left rail portions 5a is installed on the front and rear portions of the facility surface 4, and between the front and rear guide rails 5, the two rail portions 5a are bounded by a mountain-shaped top. An even number (six in the present embodiment) of roof blocks 6a are folded in the vertical direction, and roof bodies 6 configured to be expandable are provided.

More specifically, as shown in FIG. 2, each roof block 6a is composed of a framing frame composed of a beam member 7 and a purlin member 8, and an exterior member 9 attached outside the framing frame.
Are connected by a hinge 10 in an accordion manner so as to be foldable, and a hinge 10 is also attached to the tip of the top roof block 6a and the bottom end of the bottom roof block 6a. Both ends of the hinge 10, that is, both ends of each of the hinges 10 located at odd-numbered positions from above are attached to the rail 5 a of the guide rail 5,
Each is engaged via an opening / closing drive device 11 described later, and only the hinge 10 located at the lowermost end is directly supported by the lower end of the rail portion 5a. In FIG. 2, reference numeral 12 denotes a flexible waterproof sheet for covering the hinge 10 at the folded position. Although not shown, a rubber packing and a drain plate are provided on the top end of each roof block 6a in correspondence with each other to prevent rainwater from entering when the roof block 6a is closed.

As shown in FIGS. 3 and 4, details of the opening / closing drive device 11 are provided at the end of each lower hinge 10 excluding the base position.
A support frame with a concave cross section that straddles the rail 5a from below
Attached to the support frame 13, the pinion gears 14 arranged at the front and rear portions of the support frame 13 in the vertical direction are respectively supported, and the pinion gears 14 are engraved on the upper and lower surfaces of the rail portion 5a along the longitudinal direction. The gears 17 of the motor 16 respectively meshed with the racks 15 and mounted on the support frame 13 are meshed with transmission gears 18 provided on a shaft 20 of an arbitrary pinion gear 14 via an intermediate gear 19 to drive the motor 16. The force is transmitted from the gear 17 to the pinion gear 14 via the intermediate gear 19 and the transmission gear 18, and the pinion gear 14 is rolled while maintaining the mesh with the rack 15, so that the hinge 10 is moved vertically along the rail 5a. It can be moved to.

With the above configuration, as shown by the solid line in FIG.
When both roofs 6 are closed together with their palms, the facility surface 4 can be used as an indoor facility.

On the other hand, when the facility surface 4 is used as an outdoor facility, each roof block 6a is folded as shown by a two-dot chain line in FIG. That is, when the motor 16 of each opening / closing drive device 11 is rotated in a required direction, the rotational force of the motor 16
Since the pinion gear 14 is transmitted to the pinion gear 14 via the intermediate gear 19, the transmission gear 18, and the shaft 20, the pinion gear 14 holds the mesh with the rack 15 on the upper and lower surfaces of the rail 5a.
It will be moved down along 5a. Further, since the movement of the pinion gear 14 is transmitted to the odd-numbered hinge 10 via the support frame 13, each roof block 6a is sequentially folded with the lowermost hinge 10 as a base point,
As a result, the space above the facility surface 4 is opened. In the folding step, each open / close drive device
When the eleven motors 16 are driven simultaneously, it is necessary to sequentially stop the motors 16 of the opening / closing drive device 11 arriving at the base point. Further, when the motors 16 of the respective opening / closing drive devices 11 are driven with a difference in speed, the motors 16 are simultaneously stopped at the base point. Therefore, in the expansion process at the time of closure,
What is necessary is just to perform the operation reverse to the above.

As described above, when the facility surface 4 is used as an outdoor facility, each roof 6 is folded in units of the roof blocks 6a, and is folded to be stored, so that it is stored in the ground as in the related art. There is no need to build a gap, and the whole can be manufactured at low cost.

In the above, the opening / closing drive device 11 for the roof 6 is individually mounted at the end of each lower hinge except for the base position by the rack and pinion method,
Can be opened and closed, and fine adjustment of the opening and closing speed and the interval between the lower hinges 10 can be easily performed. In addition, since the flexible waterproof sheet 12 is provided at the hinge 10 at each folding position of the roof 6, it can freely follow the opening / closing operation of the roof 6, and the intrusion of rainwater and wind is reliably achieved with a simple structure. Can be prevented and maintenance is easy.

The movable roof of the present invention can be used for sports facilities, factories,
The present invention can be applied to any facility such as a farm or a storage warehouse for articles that do not like humidity, and it is needless to say that various changes can be made without departing from the gist of the present invention.

[Effects of the Invention] As described above, according to the movable roof of the present invention, the mountain-shaped guide rails are installed on the front and rear portions of the facility surface, and an even number of roof blocks are provided between the front and rear guide rails. Are successively arranged by hinges so as to be freely foldable, are arranged separately at the top of the mountain shape, and are foldable along the guide rail from the lower end as a base point so as to be expandable. A support frame that straddles a guide rail from above and below at the end of each lower hinge except for a pinion gear supported by the support frame and meshed with a rack engraved on the upper and lower surfaces of the guide rail; and the pinion gear. And an open / close drive device comprising a motor for driving the motor, and furthermore, a hinge portion at each of the folding positions is covered with a flexible waterproof sheet. Since it has a configuration, it exhibits the following excellent effects.

When the facility surface is used as an outdoor facility, the roof can be stored by folding the roof along the guide rails.

The roof opening and closing drive system is of the rack and pinion type, which is individually mounted at the end of each lower hinge except for the base position, so that the roof can be opened and closed with a small force and the roof can be opened and closed. Fine adjustment of the opening / closing speed of the body and the interval of the lower hinge can be easily performed.

Since a flexible waterproof sheet is used to prevent the invasion of wind and rain from the hinge part, it is possible to freely follow the opening and closing operation of the roof, and maintenance is easy.

It can be manufactured at low cost without building a large storage space in the ground.
