Abstract

PURPOSE:To minimize the volume of overlaid roofs by forming an openable roof of a fixed roof installed on the side of a home base, travel lanes for mobile roofs extending from both ends of the fixed roof in the direction toward an outfield and a plurality of the mobile roofs formed in different radius curvature. CONSTITUTION:A home base 3 is covered with a fixed roof 5 and travel lanes 6 are formed stretching from both ends of the fixed roof 5 in the direction toward an outfield 4. The upper faces of the travel lanes 6 are constructed in two stages and each one travel rail 7 is laid on each one of the staged upper faces. Then mobile roofs 8 and 9 covering the fixed roof 5 and the central part of a ground 1 are made to be having the same center of curvature in the direction of height, but to be different in radius of curvature. The mobile roofs are further made in such layered structure that the mobile roof 9 can be moved toward the fixed roof 5 and is overlaid thereon the mobile roof 8 can be further overlaid thereon. Thereby overlaying of the roofs can be made in minimum volume when the roof is opened.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof that can open and close the top of a building as desired by opening and closing the roof.

(Prior Art) Among the conventional domes of this kind with retractable roofs, there is one called a skylight dome by the present applicant. This skylight dome of the present applicant supports a movable roof with arch beams extending in six directions from the center point of the dome top, and supports the movable roof with a traveling rail formed on the arch beam and a trolley that rides on this traveling rail. The dome is supported so that it can be opened and closed, and while this arch beam can be used to accommodate a variety of events, it also means that a fixed roof remains around the top of the dome. The problem was that it sometimes left a residue on the surface, and it lacked an outdoor feeling and left a feeling of pressure. Therefore, we divided the roof into two types: one that moves in parallel and one that moves in a rotational manner, and a roof that moves these parallel and rotational roofs toward the fixed roof by covering a fixed roof installed at one end of the dome. There is also. This requires the installation of functions for both rotational movement and parallel movement, which has the disadvantage of complicating the structure, and at the same time, the roof that performs rotational movement has to travel a long distance. There was a constraint that the dome had to be formed with a radius of curvature that would allow rotational movement.

Therefore, it may be possible to limit the movement direction of the retractable roof to parallel movement and move it closer to one end of the dome.Such retractable dome roofs already exist, but this is because the height of each movable roof is different. The movable roofs are structured in steps, and the tallest ones are successively brought to one side of the dome, and the shorter ones are placed below them.

(Problem to be Solved by the Invention) However, when the movable roof is a parallel movable roof configured in a plurality of steps, the inclination angle of each movable roof is different, so even when it is stowed to one side, the stowed state becomes bulky. The drawback was that the retractable roof required a large amount of storage space.

The present invention has been made in view of the above circumstances, and its purpose is to make a retractable roof a parallel movable type, and when a plurality of movable roofs are configured as a retractable roof, each movable roof can be opened and closed at random. To provide a retractable roof which can reduce the volume of a housed state as much as possible.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention includes a fixed roof disposed on the home base side, and a running path extending parallel to each other toward the outfield from both ends of the fixed roof. It consists of a plurality of moving roofs that span the running path and have the same center of curvature in the height direction and different radii of curvature.

(Function) A plurality of movable roofs straddle running paths that extend parallel to each other toward the outfield from both ends of the fixed roof placed on the home base side, and move in parallel from the fixed roof toward the outfield. At this time, the movable roofs each have the same center of curvature in the height direction, but have different radii of curvature, so they can move freely while overlapping each other, or they can move in opposite directions. I feel free. Therefore, when moving these movable roofs toward a fixed roof, the height of each movable roof should be set to be efficient and not to hit the fixed roof, thereby minimizing the bulk of the fixed roof. It is now possible to do so.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a baseball field with half from the center without a roof.This baseball field has a fan-shaped field 1, with spectator seats 2 surrounding the field. 3 is thicker and gradually becomes thinner toward outfield 4.

Then, cover the side where the home base 3 is with a fixed roof 5,
A running path 6 is formed extending from both ends of the fixed roof 5 in parallel to the outfield 4 direction.

The side surface of the running path 6 has an outer wall whose top surface gradually draws a gentle arc from the fixed roof 5 toward the outfield 4 and whose heights become similar, and there is a step on the top surface. form,
A traveling rail 7 is laid on the top surface of each step. That is, the structure of the running path 6 is such that the top surface, which is an outer wall, has a two-tier structure, and a running rail 7.7 is laid on each top surface.

The fixed roof 5 and the movable roof each have the same center of curvature in the height direction and have different radii of curvature. In this embodiment, the movable roof 8 covers the central part of the ground 1. and a movable roof 9, and one fixed roof 5 and 2.
The movable roof 8 and 9 constitute a retractable roof. That is, the movable roof 8 covering the central portion of the ground 1 has the largest radius of curvature, followed by the movable roof 9 and then the fixed roof 5, which have gradually smaller curvature radius. As a result, when each of the movable roofs 8, 9 moves toward the fixed roof 5, the movable roof 9 overlaps the fixed roof 5, and the movable roof 8 further overlaps the fixed roof 5, resulting in a laminated structure.

A running wheel 10 that rides on a running rail 7 is fixed to both ends of each of the movable roofs 8 and 9, and the running wheels 10 of the movable roof 8
is located at the outermost side of the running path 6, and a moving roof 9 is located inside it.
The running wheels 10 of are located. The details of these running wheels 10 and running rails 7 will be explained in detail with reference to FIGS. 4 and 5. These moving roofs 8,9 are driven as shown in FIG. Two endless winches 11.11 are installed at the bottom of the running path 6, and the endless winches 11
are used separately for the movable roof 8 and for the movable roof 9, respectively. In addition, as explained earlier, the rail span of the movable roof 9 is narrower than the rail span of the movable roof 8, and at the same time the center of curvature is the same in the height direction, the radius of curvature is the same as that of the movable roof. Since the movable roof 9 is smaller than the movable roof 8, the movable roof 9 can freely pass under the movable roof 8, and the endless winches 11 and 11 can move the movable roof 8 and the movable roof 9 respectively. Two units are installed separately so that they can be driven independently. Sheaves 12° 12 for hanging and rotating wire lobes are pivoted on each end of the running rail 7 laid on the top surface of the running path 6, and the wire lobes are moved from the endless winch 11 through the sheaves 12. An endless wire row 113 is hung and rotated separately on the roof 8 and the movable roof 9. That is, by fixing the running wheel 10 to the wire lobe 13 which is looped around the endless winch 11 and the sheave 12 and rotated, when the direction of rotation of the endless winch 11 is changed, the respective moving roofs 8° 9 can be moved onto the running path 6. Next, A-A along the line of arrow A in Figure 1.
A cross section is shown in FIG. 3, and the state of each roof will be explained.

The fixed roof 5 is configured to cover the spectator seats 2 located at the end on the base 3 side, and the movable roof 8 is located so as to cover almost the center top of the ground 1. A movable roof 9 covers the side ends. When opened, the movable roof 9 overlaps the fixed roof 5, and the movable roof 8 further overlaps thereon. Therefore, by strictly selecting the radius of curvature of each of the movable roofs 8 and 9, these movable roofs 8.9
This makes it possible to minimize the bulkiness of the roof when it overlaps the fixed roof 5.

FIG. 4 shows details of the running wheel 10, in which a bogie frame 15 having a trapezoidal shape in side view is fixed to the end of the structural member 14 constituting each movable roof 8. A horizontally projecting side roller 16 is provided on the outside of the roof 15, and this side roller 16 restricts the movable roofs 8, 9 from spreading laterally in the horizontal direction due to the vertical load received from snow or wind pressure, thereby preventing wheels from falling off. are doing. Moreover, this bogie frame 15 has a movable roof 8,
A wire fitting 17 for locking a wire lobe 13 for driving the wire lobe 9 is provided.
is fixed to either the front or rear end of the bogie frame 15, and its shape may be any shape as long as it can be engaged with a hook integral with the wire lobes 13 protruding laterally.

The state of the running wheel 10 is shown in FIG. 5, and FIG. 5 is a drawing taken in the direction of arrow B in FIG. 1. As shown in the figure, the upper end surface of the running path 6 has a two-layer structure, upper and lower, and the upper surface 18 located above is located on the outer side of the ground 1 than the lower surface 19, and is connected to the upper layer of the movable roof 9. Moving roof 8
A running rail 7a on which running wheels 10a run is laid. That is, the rail span of the rail 7b of the running wheel 10b that supports the movable roof 9 located at the lower layer of the movable roof 8 is narrower than that of the rail 7a that is located on one of the lower surfaces of the travel path 6 and on the upper surface 18. It is something that Then, each upper stage surface 18. The side rollers 16, 16 come into contact with the vertical plane forming one step of the lower step surface to limit the lateral movement of each movable roof 8.9, and the respective running wheels 10a and 10b are Structural material 14a of moving roof 8 and structural material 14 of moving roof 9
It is fixed at the end of b with a shaft or the like to allow some rotational movement.

(Effects) As explained in detail above, according to the retractable roof of the present invention, the fixed roof is placed on the home base side, so the spectator's line of sight naturally turns toward the outfield, and the roof is in the direction of the line of sight. Since there is no such thing, there is no obstacle to the feeling of openness.In addition, the movable roof is designed to move across running paths extending parallel to the outside field from both ends of the fixed roof, so the movable roof is different from the fixed roof. It moves parallel towards and fits,
When opening the movable roof, it is only necessary to move it towards the fixed roof, which minimizes the distance of movement and also allows the power capacity to be relatively small compared to the vertically movable type of movable roof. become.

Furthermore, since each of the multiple moving roofs has the same center of curvature in the height direction and different radii of curvature, the length in the moving direction can be shortened to create a multi-layered structure. This makes it possible to minimize the amount of space that gets stuck when the roof is opened. That is, in the fully opened state when each movable roof has finished moving toward the fixed roof, the height and width in the overlapping direction are minimized.
