Abstract

PURPOSE:To shorten the time of opening and closing by a method in which a crescent fixed roof is provided to one top end of a round opening, and a slewing roof and a rotary roof whose lapped end portions are connected with a rotary shaft are provided to the other end. CONSTITUTION:The top space of a round peripheral wall 2 is partly covered with a crescent fixed roof 3, and the other portion of the top space is covered with a triangular rotary roof 4 and a slewing roof 5. A rotary shaft 6 is provided on the turning point of the roof 5 to pivotally support the roof 4 and the roof 5 in a lapped manner. When a powered truck 14 is traveled, the roof 5 moves toward the fixed roof 3 on a slewing rail 7 along the circumferential direction of the wall 2. The shaft 6 moves integrally and the roof 4 moves rotationally around the shaft 6. Excellent opening feeling can thus be obtained without remaining beam in the opening.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a retractable roof suitable for all-weather buildings such as sports stadiums and baseball fields.

(Prior Art) Generally, all conventional retractable roofs have a laminated structure in which the roofs are stacked in several tiers, and these are simultaneously slid or run in a sliding manner to open and close the top of the building.

For example, there have been methods such as attaching running wheels to the beams that support the roof so that the roof members can run on the beams, or making the beams expandable and retractable so that they can move and open and close together with the roof members.

When these movable roofs are opened, they are placed on top of each other so that the area of the opening is wide. Similarly, in order to increase the area of the opening, it is also being considered to make the retractable roof a folding structure.

(Problem to be solved by the invention) Since the movable roof that constitutes the retractable roof needs to be supported stably so that it can be opened and closed freely, when a beam is left at the opening, there is a drawback that the opening lacks a sense of openness. .

In addition, folding roofs tend to have complicated roof structures;
Furthermore, there were also problems with the material and durability of the roof membrane.

Furthermore, when trying to shorten the opening and closing time by simultaneously opening and closing each member of the movable roof that makes up the retractable roof, the moving power of the movable roof acts as lateral pressure on the roof members, causing the movable roof to bend. It had become. In other words, the roof member is deformed in the plane direction.

The present invention was made in view of the above circumstances, and its purpose is to provide an excellent sense of openness without leaving any beams in the opening when the roof is opened, and to provide a retractable roof with a high opening ratio while minimizing the site area. The purpose of the present invention is to provide a retractable roof that can be efficiently stored in the movable roof and at the same time prevent the movable roof from being deformed by the reaction of the moving power.

(Means for Solving the Problems) In order to achieve the above object, the retractable roof of the present invention comprises a half-moon-shaped fixed roof at one end of the flat or substantially circular opening top surface, and further comprises a half-moon-shaped fixed roof. is divided into right and left sides by a diametric line extending from the center of the inner edge of the circle through the approximate center point of the circle forming the top surface to the other end, and on each side, from the outer peripheral edge of the other end to the inner angle thereof. Of the four inwardly curved substantially triangular roof members obtained by dividing the center radially, each of the two roof members divided to the left and right of the diameter line is the two roof members divided to the left and right of the diameter line. The roof members are vertically connected to each other at a position near the outer periphery of the other end, and the connecting point is used as a rotation axis to rotate the roof members closer to one diameter line. It is a movable roof, and the outer peripheral edge of the outer roof member that overlaps with the pivoting roof is a pivoting roof that pivots along the pivot axis toward the fixed roof along the circumferential direction of the top surface, and the diameter line is A guide track parallel to a line segment extending on the fixed roof is laid on the fixed roof, and a restraining guide rail along the rotation trajectory when the rotating roof overlaps the rotating roof is laid on the rotating roof. The running wheels, which are placed in the formed concave groove and support the rotating roof, are restrained from movement outside the movement axis direction by the restraint guide rails.

(Function) When the pivoting roof pivots toward the fixed roof on the circumference of the opening top surface, the pivot point that connects the pivoting roof and the pivoting roof moves together in the direction of rotation of the pivoting roof. do.

At that time, the edges of the rotating roofs sandwiching the diameter line of the opening top surface receive a reaction force from the movement of the rotating roof in the rotating direction, and the edges of the rotating roofs are moved relative to the center point in proportion to the amount of movement of the rotating roof. While being restrained in the guide direction of the restraint guide rail, the robot moves toward the swinging roof so as to overlap.

At the same time, the rotating roof moves toward the fixed roof along the direction guided by the guide track on the fixed roof, and finally the rotating roof fits on the fixed roof and overlaps with the rotating roof. It also fits towards a fixed roof.

As described above, the rotating roof and rotating roof fit onto the fixed roof and open the arena top, but the movable roof and rotating roof move from the fixed roof to cover the arena top. In some cases, the behavior is exactly the opposite.

In this way, the movement reaction force when the rotating roof moves is received by the rotating roof, and the moving direction of the rotating roof that overlaps the rotating roof is determined by the guide track for the rotating roof and the groove inner wall of the restraining guide rail or the wheel flange. In order to forcibly guide the guide track in the axial direction, the diameter line of the top surface passes along the fixed roof and along the guide track and restraint guide rail, these guide tracks This guides the movable roof in a predetermined direction of movement without deforming it while preventing the force acting in the lateral direction.

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

FIG. 1 shows a plan view of a dome roof 1 made of a retractable roof according to the present invention, and this dome roof 1 has a semicircular eave fixed thereto that protrudes inwardly along the outer circumferential edge of an outer circumferential wall 2 erected in a circular manner. It is a retractable roof consisting of a roof 3, a rotating roof 4, and a rotating roof 5.

That is, the fixed roof 3 is formed in a half-moon shape that covers a part of the inner entrance space surrounded by the outer peripheral wall 2, and the peripheral edge forming the half-moon shape matches the radius of curvature of the outer peripheral wall 2, and the inner edge The portion is recessed in the outer diameter direction of the outer peripheral wall 2. The remaining ceiling space is a rotating roof4. It is covered with a rotating roof 5.

A diameter line segment of the outer circumferential wall 2 that passes from the center of the outer circumferential side of the fixed roof 3 to the center of the inner circumferential side, proceeds linearly through the opening top not covered by the fixed roof 3, and reaches the upper edge of the outer circumferential wall 2. A rotation axis 6 is provided on the rotation point of the rotating roof 5, with the left and right of the intersection with the outer peripheral wall 2 as rotation points, and the rotation axis 6 allows the rotation roof 4 to overlap the rotation roof 5. It is rotatably supported.

That is, the side in contact with the outer circumferential wall 2 is covered with the rotating roof 5, and the end side of each rotating roof 4 in contact with the outer circumferential wall 2 is pivoted by the rotation shaft 6.

The rotating roof 5 has a triangular shape with an outside curved along the curvature of the dome roof 1, and the rotating roof 4 has a flat surface that is a curved surface that is adjacent to the rotating roof 5 and overlaps the rotating roof 5. It has a triangular shape.

Further, the tip portion of the rotating roof 4, that is, adjacent to the fixed roof 3, is a convex curved surface that draws a circular arc along the inner peripheral edge thereof, and is located on the left and right sides of the diameter line of the outer peripheral wall 2. The rotating roof 5 is located outside the rotating roof 4.

As a result, the dome roof 1, which has become a retractable roof, covers the top surface of the outer circumferential wall 2 with a fixed roof 3 and a rotating roof 5 which rotates by 4 degrees. These rotating roofs 4 and 5
is supported so that it can move freely by a trolley that runs on guide rails.

The swing roof 5 is supported by a swing rail 7 provided in the circumferential direction of the upper end surface of the outer peripheral wall 2 and a swing auxiliary rail 8 provided on the fixed roof 3 with the same radius of curvature as the swing rail 7.

In addition, for the rotating roof 4, two parallel guide tracks 9 are provided on the fixed roof 3 along the diameter line of the outer peripheral wall 2, and these guide tracks 9 are used to connect one corner of the rotating roof 4. is supported by a truck 11, and a corner portion overlapping the swing roof 5 on the opposite side is supported by a truck 12. The restraining guide rail 13 that makes the truck 12 travel is arranged so that the rotating roof 4 rotates around the rotation axis 6 and moves along the locus of movement of the truck 12 when the rotating roof 4 overlaps the rotating roof 5. Rails are laid on the side walls and bottom of a large rectangular groove on the surface.

A swing rail 7 supporting the swing roof 5 on the outer peripheral wall 2
The truck for traveling is a power truck 14, and the rotating roof 5 is moved toward the fixed roof 3 by the running force of the power truck 14.

The driven truck 15 on the swing auxiliary rail 8 supporting the other swing roof 5 or the guide track 9 supporting the swing roof 4
The bogie running on the restraint guide rail 13 is a bogie without power.

When the rotating roof 4 and the rotating roof 5, which are positioned to close off the arena portion covered by the dome roof 1, are opened, when the power truck 14 is run, the rotating roof 5 will close the outer peripheral wall 2.
It travels toward the fixed roof 3 on the turning rail 7 along the circumferential direction.

At this time, the rotating shaft 6 moves integrally with the movement of the rotating roof 5, so that the adjacent facing surfaces of the rotating roofs 4.4 that are adjacent to each other across the diameter line of the outer peripheral wall 2 are It receives the movement reaction force of the swing roof 5 acting in the direction. As a result, the rotating roof 4 rotates about the rotating shaft 6 so as to overlap with the rotating roof 5 as the rotating roof 5 rotates.

In this way, as shown in FIGS. 2 and 3, the pivoting roof 5 and the pivoting roof 4 finally overlap on the fixed roof 3 to open the circular top surface surrounded by the outer peripheral wall 2.

At this time, the guide track 9 and restraint guide rail 13 have a structure that absorbs the reaction force for converting the force of the rotating roofs 4, 4 adjacent to each other and pushing each other into rotational movement of the rotating roof 4. As shown in FIG.

That is, since both the guide track 9 and the restraint guide rail 13 have the same structure, the restraint guide rail 13 is shown in FIG.
I will show and explain this.

The trolley 12 is swingably attached to the back of the rotating roof 4 with a shaft 16, and rails 17 are laid on the bottom and both sides of a groove formed on the surface of the rotating roof 5 to have a rectangular cross section. The wheels 18 run on the rails 17 on the bottom of the groove, and the wheels of side pressure receivers that protrude horizontally on both sides of the bogie frame hit the rails 17a laid on the sides of the groove. The side pressure receiving wheels are wheels 19, and the side pressure receiving wheels 19 completely prevent the cart 12 from wobbling laterally.

Therefore, when the rotating roof 5 moves on the rotating rail 7 along the circumferential direction of the outer peripheral wall 2, the rotating roof 4 receives a movement reaction force on the guide track 9, and also receives a movement reaction force in the direction of the moving axis of the truck 12. The force acting in the direction across the rotation axis 6 and the restraint guide rail 13 is regulated by the restraint guide rail 13.
This prevents the rotating roof 4 from being bent or deformed.

(Effects) As explained in detail above, according to the retractable roof according to the present invention, a half-moon-shaped fixed roof is formed at one end of the semi-circular opening top surface, and the other parts are formed on the opening top surface. There are two roof members that overlap each other on both sides of the diameter line, and the outer roof member of these two roof members is a rotating roof that pivots along the circumferential direction of the opening top surface. The roof member is a rotating roof that moves in response to the movement reaction force of the rotating roof. The restraint guide rail is placed in a large groove formed in the pivot roof, and rotates along the rotation trajectory when it overlaps the pivot roof or the pivot roof, with the center of rotation as the center of rotation. Since the movement of the roof in the direction of rotation is restricted, the rotating roof and the rotating roof can be moved simultaneously without the need for a rotating roof or a beam to support the rotating roof on the top surface of the opening. . Therefore, it has an excellent open feeling and has the effect of shortening the opening/closing time.

Furthermore, since the position of the traveling carriage traveling inside the restraint guide rail can be kept constant by the rotation axis and the restraint guide rail, that is, the position of the traveling carriage traveling inside the restraint guide rail from the rotation axis of the rotating roof can be kept constant. Since the separation distance to the cart can be maintained constant, it is effective in preventing bending and deformation of the rotating roof.
