Description

TECHNICAL FIELD The present invention relates to a retractable roof preferably applied to a baseball field in which the roof of the building can be arbitrarily opened and closed by opening and closing the roof.

<< Prior Art >> Among conventional dome and the like having such a retractable roof, there is a skylight dome in the case of the present applicant. The skylight dome according to the applicant of the present invention supports the moving roof with arch beams that spread in all directions from the center of the dome top, and the traveling roof configured with the arch beams and the carriage that rides on the traveling rail provide the moving roof. It supports openable and closable movements and can be used for various events using this arched beam. However, a fixed roof remains around the top surface of this dome. There was something left on the surface, and there was another shortcoming that I felt a little feeling of being outdoors and left a feeling of oppression. Therefore, the roof is divided into those that move in parallel and those that rotate, and those that move the parallel roof and rotary roof to the side with the fixed roof while covering the fixed roof provided at one end of the dome. There is also. This has the drawback of complicating the structure, since it has to install both functions of rotary motion and parallel fluctuation, and at the same time, the moving distance of the roof that performs rotary motion becomes long. There was a constraint that the dome had to be formed with a radius of curvature that allowed pivotal movement.

Therefore, it is conceivable to limit the movement direction of the open / close roof to parallel movement and bring it closer to one end of the dome.Although there is already such an open / close dome roof, the height of each movable roof is different. The moving roof, which has a stepped structure, is gradually moved to one of the domes from the tallest one, and the lower ones are successively accommodated under the dome.

<< Problems to be Solved by the Invention >> However, when the moving roof is a parallel moving roof having a plurality of staircases, the moving roofs have different inclination angles, so that the moving roofs may not fit even in one side. There was a drawback that the retractable roof could be stored in a large scale.

The present invention has been made in view of the above circumstances, and an object thereof is to make an openable and closable roof a parallel movement type, and when a plurality of movable roofs are configured as an openable and closable roof, each movable roof is randomly opened and closed. It is possible to provide a retractable roof that can be made to be at the same time as the volume of the housed state can be made as small as possible.

<< Means for Solving the Problem >> In order to achieve the above object, the baseball field openable roof of the present invention is a baseball field openable roof with the seats of the spectators seated high on the home base side and low on the outfield side. A pair of fixed roofs that cover the seats on the home base side, and a pair of parallel roofs extending from both ends of the fixed roof toward the outfield direction and along the route in which the outfield side is lower than the home base side. So that they are stacked on top of each other,
A plurality of different heights of curvature are formed at the same center of curvature, and the heights are different from each other. The plurality of traveling paths are provided across the pair of traveling paths and are moved from the fixed roof side to the outfield side. It is characterized by comprising a fixed roof and a moving roof that covers the baseball field in an openable and closable manner.

<< Operation >> A plurality of moving roofs that extend from the both ends of the fixed roof covering the spectator seats on the home base side of the baseball field in parallel to the outfield direction move in parallel from the fixed roof direction to the outfield direction. At that time, the moving roofs are formed in different heights with different radii of curvature at the same center of curvature so that they can be stacked on top of each other, so they can move freely while overlapping each other. It is also free to reverse the moving direction of each other. Therefore, when moving these moving roofs toward the fixed roof, the height of each of them should be set so as not to be wasted, and the movable roof should not hit the fixed roof to minimize the bulkiness of the housed state. It is possible to set. Furthermore, since the running path on which the moving roof travels is formed with a route in which the outfield side is lower than the home base side, considering that it is a baseball field, the outfield side is imitated according to the arrangement of the spectator seats of the baseball field. It is possible to position the traveling road height of, that is, the traveling road can be set lower than the spectator seats on the outfield side, and it is possible to secure a vast field of view on the outfield side where the traveling road is not in sight, The height can be set high on the home base side, and the height space required for a baseball game can be secured without increasing the size of the moving roof.

«Examples» Hereinafter, preferred examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a baseball stadium with the roof half of which is shown from the center. This stadium has a spectator seat 2 surrounding a fan-shaped ground 1, and the spectator seat 2 is a home base. 3 is thicker and higher, and gradually becomes thinner and lower toward the outfield 4. One side of the home base 3 is covered with a fixed roof 5, and a pair of running paths 6 extending in parallel to the outer field 4 from both ends of the fixed roof 5 is formed.

The side surface of the running path 6 is an outer wall whose top surface gradually lowers from a position with the fixed roof 5 toward the outer field 4 by drawing a gentle arc, and a step is formed on the top surface. Formed, and traveling rails 7 are laid on the top surfaces of the respective step portions.
That is, the structure of the traveling path 6 has a two-tiered top surface which is an outer wall, and the traveling rails 7, 7 are laid on each top surface. Then, the fixed roof 5 and the plurality of moving roofs described later are formed at different heights with different radii of curvature at the same center of curvature so as to be vertically overlapped with each other. In the example, there are a movable roof 8 and a movable roof 9 that cover the central part of the ground 1 in an openable and closable manner. A fixed roof 5 and two movable roofs 8 and 9 constitute a retractable roof. Numerals 8 and 9 are provided so as to straddle a pair of traveling paths 6, and traveling on the traveling paths 6 is freely possible. That is, the movable roof 8 covering the central portion of the ground 1 has the largest radius of curvature, the movable roof 9 next, and then the fixed roof 5 in order of decreasing radius of curvature. As a result, when the movable roofs 8 and 9 are moved along the traveling path 6 toward the fixed roof 5, the movable roof 9 is overlapped on the fixed roof 5, and the movable roof 8 is further overlapped thereon. It has a simple laminated structure. Each moving roof
Traveling wheels 10 for riding on the traveling rail 7 are fixed to both ends of 8, 9 and the traveling wheels 10 of the movable roof 8 are located on the outermost side of the traveling path 6, and the traveling roof 9 travels inside thereof. Wheel 10 is located. Details of the traveling wheels 10 and the traveling rail 7 will be described in detail with reference to FIGS. 4 and 5. These moving roofs 8,9
Are driven as shown in FIG. Two endless winches 11 and 11 are installed below the traveling path 6, and these endless winches 11 are used separately for the movable roof 8 and the movable roof 9, respectively. In addition, as described above, the rail span of the moving roof 9 is narrower than the rail span of the moving roof 8 and has the same curvature center point in the height direction, and at the same time the radius of curvature of the moving roof 8 is the same. Since the moving roof 9 is smaller than the moving roof 9
Is free to go under the moving roof 8 and the endless winches 11 and 11 are separately installed so that they can independently drive the moving roof 8 and the moving roof 9, respectively. It is a thing. And the road 6
Sheaves 12 and 12 around which the wire rope is hung are axially attached to the respective ends of the traveling rail 7 laid on the top surface of the movable roof 8 and the movable roof 9 via the endless winch 11 and the sheave 12, respectively. The endless wire rope 13 which is separately hung around is hung around. That is, by fixing the traveling wheel 10 to the wire rope 13 wound around the endless winch 11 and the sheave 12 in a ring shape, when the rotation direction of the endless winch 11 is changed, the respective movable roofs 8 and 9 are changed. It can be moved to the traveling path 6. Next, the state of each roof will be described with reference to FIG. 3 showing an AA cross section taken along the line A in FIG.

The fixed roof 5 is configured to cover the top of the spectator seat 2 located at the end on the base 3 side, and the movable roof 8 is positioned so as to cover almost the central top of the ground 1. The movable roof 9 covers the end on the side. When it is opened, the movable roof 9 overlaps the fixed roof 5, and the movable roof 8 further overlaps the fixed roof 5. Therefore, by strictly selecting the respective curvature radii of the movable roofs 8 and 9, the bulky state when these movable roofs 8 and 9 overlap the fixed roof 5 can be set to the minimum.

FIG. 4 shows the details of the traveling wheel 10. The traveling wheel 10 has a bogie frame 15 having a trapezoidal side view fixed to the end of the structural member 14 constituting the movable roofs 8 and 9, and further the bogie frame. Side rollers 16 that project horizontally are provided on the outside of 15, and the side roofs 16 prevent the movable roofs 8 and 9 from laterally expanding horizontally due to the vertical load received by snow and wind pressure, preventing wheel removal. are doing. Further, the bogie frame 15 is provided with a wire mounting bracket 17 for locking the wire rope 13 for driving the movable roofs 8 and 9, and the wire mounting bracket 17 is provided at one of the front and rear ends of the bogie frame 15. Any shape may be used as long as it is fixed and the hook integral with the wire rope 13 protruding laterally of the wire rope 13 can be locked.

The state of the traveling wheels 10 is shown in FIG. 5, and FIG. 5 is a drawing shown in the direction of arrow B in FIG. As shown in the figure, the upper end surface of the traveling path 6 has a two-tiered upper and lower structure, and the upper step surface 18 located on the upper side is outside the lower step surface 19 with respect to the ground 1, and is on the upper layer of the movable roof 9. A running rail 7a for running the running wheels 10a of the moving roof 8 located is laid. That is, the rail span of the rail 7b of the traveling wheel 10b that supports the movable roof 9 located under the movable roof 8 is narrower than that of the rail 7a on the lower step surface 19 of the traveling path 6 and on the upper step surface 18. There is something. And
The side rollers 16 and 16 hit the vertical surfaces forming the steps of the upper and lower surfaces 18 and 19, respectively, to limit the lateral movement of the movable roofs 8 and 9, and the respective driving theory 10a and driving theory 10b are structural materials 14a and moving roof 9 of moving roof 8.
The end of the structural member 14b is stopped by a shaft or the like so as to allow a slight rotational movement.

<Effect> As described in detail above, according to the retractable roof of the baseball field of the present invention, since the fixed roof is arranged on the home base side, the spectator's line of sight naturally faces the outfield direction, and in the line of sight Since there is no roof, there is nothing that hinders the feeling of openness. In addition, since the moving roof is designed to move from both ends of this fixed roof across the running paths that extend in parallel in the outfield direction, the moving roof moves in parallel to the fixed roof and is settled. The moving direction when opening is only required to move toward the fixed roof, and the moving distance can be minimized and the moving power can be made relatively small compared to the vertical moving type of the moving roof. .

Furthermore, since each of the plurality of moving roofs is formed in different heights with different radii of curvature at the same center of curvature so that they are stacked on top of each other, the length in the moving direction can be shortened. It is possible to make a laminated structure of several steps, and it is possible to minimize the fit state when the roof is opened. That is, in the fully opened state when all the movable roofs have moved to the fixed roof, the height in the overlapping direction and the width thereof are minimized. Furthermore, since the running path on which the moving roof travels is formed with a route in which the outfield side is lower than the home base side, considering that it is a baseball field, the outfield side is imitated according to the arrangement of the spectator seats of the baseball field. The height of the road can be set lower, that is, the road can be set lower on the outfield side than the audience seats, and a vast field of view can be secured on the outfield side where the road is not visible. , It can be set high on the home base side without increasing the size of the moving roof,
The height space required for baseball games can be secured.
