Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a retractable roof suitable for a building in which an athletic stadium, a baseball field, etc. are all weather type.

<< Prior Art >> In general, each of the conventional openable roofs has a laminated structure in which the roofs are stacked in several stages, and these are simultaneously slid or run in a sliding manner to open and close the top of the building.

For example, a method has been adopted in which traveling wheels are attached to a beam supporting a roof so that the roof member runs on the beam, or the beam is configured to be extendable and retractable so that the beam is moved and opened / closed together with the roof member.

These are designed so that when the movable roof is opened, the areas of the openings are widened by overlapping each other. Similarly, in order to increase the area of the opening, it is also considered that the retractable roof has a folding structure.

<Problems to be solved by the invention> Since the movable roof that constitutes the opening-closing type roof needs to be supported stably in a freely openable and closable manner, there is a drawback that the opening part lacks a feeling of opening when a beam is left in the opening part. .

Also, the structure of the roof tends to be complicated with the folding roof,
Furthermore, there were problems with the material and durability of the roof membrane.

Furthermore, when the opening and closing time is shortened by simultaneously opening and closing each member of the movable roof that constitutes the openable roof, the moving power of the movable roof acts as a lateral pressure on the roof member, which causes the movable roof to bend. Was becoming. That is, the roof member is deformed in the plane direction.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a retractable roof with a high opening ratio and a minimum open space when the roof is opened and the beam does not remain in the opening. The present invention intends to store the movable roof inside efficiently, and at the same time, provides a retractable roof in which the movable roof is prevented 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 constitutes a substantially crescent-shaped fixed roof at one end of the opening top surface of which the plane is substantially circular, and further, the fixed roof It is divided into left and right diameter line segments that extend from the center of the inner edge of the roof to the other end through almost the center point of the circle forming the top surface, and the inner angles from the outer peripheral edge of the other end on the left and right respectively. Of the four inwardly curved, substantially triangular roof members obtained by radially separating the center of the, the two roof members that are divided into the left and right sides of the diameter line segment are divided into the left and right sides of the diameter line segment. One roof member having a diameter line segment is formed by forming a step on the upper and lower sides so that the sheets overlap each other and opening, and axially connecting the upper and lower sides at a position near the outer peripheral edge of the other end and using the connecting point as a rotation axis. The roof is a rotating roof, and the outer peripheral edge of the outer roof member that overlaps with the rotating roof is along the circumferential direction of the roof and A swivel roof that swivels together with the swivel axis toward a fixed roof, and a guide track along which the diameter line segment extends parallel to the fixed roof is laid on the fixed roof. The constraining guide rail along the turning locus when the swivel roof overlaps with the swivel roof is laid in the concave groove formed in the swivel roof, and the traveling wheels supporting the swivel roof are outside the axial direction of movement in the constraining guide rail. I tried to restrain the movement of.

<Operation> When the swivel roof swivels toward the fixed roof on the circumference of the opening top surface, the swivel axis that pivotally attaches the swivel roof and the swivel roof moves integrally in the swivel direction of the swivel roof. .

At that time, the edges of the swiveling roofs sandwiching the diameter line segment of the opening top face receive the reaction force in the swivel direction of the swivel roof, and are proportional to the amount of movement of the swivel roof with the swivel axis as a center point. While being constrained in the guide direction of the restraint guide rails, move so as to overlap toward the swivel roof.

At the same time, the swivel roof moves toward the fixed roof along the direction of the guide track on the fixed roof, and finally the swivel roof fits on the fixed roof and overlaps at the same time. Also fits towards the fixed roof.

As described above, the revolving roof and the revolving roof fit on the fixed roof and open the arena top surface.However, when the moving roof and the revolving roof move from the fixed roof to cover the arena top surface. Is exactly the opposite.

In this way, the moving roof receives the movement reaction force when the swiveling roof moves, and the moving direction of the swiveling roof overlapping with the swiveling roof is the guide track for the swiveling roof and the inner wall of the groove of the restraint guide rail or the wheel flange. Since the guide rails are forcibly guided in the axial direction of the guide rails, etc., these guide rails are guided along the guide rails and the constrained guide rails along which the diameter line segment of the top surface passes along the fixed roof. While preventing the lateral force of the moving roof, the moving roof is guided in a predetermined moving direction without being deformed.

<Example> Hereinafter, a preferred example 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 according to the retractable roof of the present invention. The dome roof 1 has a substantially crescent-shaped eave that protrudes in the inner diameter direction along the outer peripheral edge of a circular outer peripheral wall 2. It is an openable and closable roof consisting of a fixed roof 3, a rotating roof 4 and a revolving roof 5.

That is, the fixed roof 3 is formed in a substantially crescent moon that covers a part of the inner ceiling space surrounded by the outer peripheral wall 2, and the peripheral portion forming the substantially crescent moon matches the radius of curvature of the outer peripheral wall 2 and the inner end The edge is recessed in the outer diameter direction of the outer peripheral wall 2. The remaining top space is covered with a swivel roof 4 and a swivel roof 5.

A diameter line segment of the outer peripheral wall 2 that passes through the center on the outer peripheral side of the fixed roof 3 and goes straight through an opening top not covered by the fixed roof 3 to reach the upper edge of the outer peripheral wall 2. The left and right of the intersection with the outer peripheral wall 2 are set as turning points, and the turning shaft 6 is provided on the turning point of the turning roof 5, so that the turning roof 4 is superposed on the turning roof 5. It is pivotally supported.

That is, the swivel roof 5 covers the side in contact with the outer peripheral wall 2, and the rotary roofs 4 are pivotally attached to the end portions in contact with the outer peripheral wall 2 by the rotary shafts 6.

The swivel roof 5 has a triangular shape whose outer side has a curvature along the curvature of the dome roof 1, and the swivel roof 4 is a plane adjacent to the swivel roof 5 and having a curved surface overlapping the swivel roof 5. It has a triangular shape. The tip of the rotating roof 4, that is, adjacent to the fixed roof 3, is a projecting curved surface that draws an arc along the inner peripheral edge thereof, and is located on the left and right of the diameter line segment of the outer peripheral wall 2. The revolving roof 5 is located outside the revolving roof 4.

As a result, the dome roof 1 which is an openable roof covers the top surface of the outer peripheral wall 2 with the fixed roof 3, the rotating roof 4, and the swiveling roof 5. These rotating roof 4 and swiveling roof 5 are movably supported by a carriage traveling on a guide rail.

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

In addition, the rotating roof 4 is provided with two parallel guide tracks 9 on the fixed roof 3 along the diametrical line segment of the outer peripheral wall 2, and on the guide track 9, one corner portion of the rotating roof 4 is provided. Is supported by the dolly 11,
The corner that overlaps the revolving roof 5 on the opposite side is trolleyed.
We support in 12. Restraint guide rails for running the dolly 12
Reference numeral 13 indicates a movement path of the dolly 12 when the rotation roof 4 rotates about the rotation axis 6 and overlaps with the rotation roof 5,
Rails are laid on the side wall surface and the bottom surface in a large groove recessed in a rectangle on the surface of the swivel roof 5.

Swivel rail 7 supporting swivel roof 5 on outer peripheral wall 2.
The trolley for traveling the vehicle is the power trolley 14, and the slewing roof 5 is moved to the fixed roof 3 by the traveling force of the power trolley 14.

Other driven vehicles 15 on the auxiliary turning rails 8 supporting the revolving roof 5 or trolleys supporting the revolving roof 4 and traveling on the guide tracks 9 and the restraint guide rails 13 are unpowered vehicles.

When the swivel roof 4 and the swivel roof 5 located at a position that closes the arena portion covered by the dome roof 1 are opened, the swivel roof 5 is moved along the circumferential direction of the outer peripheral wall 2 when the power carriage 14 is run. And travels on the turning rail 7 toward the fixed roof 3.

At that time, since the rotary shaft 6 moves integrally with the movement of the swivel roof 5, the adjacent facing surfaces of the rotary roofs 4, 4 which are adjacent to each other with the diameter line segment of the outer peripheral wall 2 sandwiched between the outer peripheral wall 2 and the swivel roof 4 are adjacent. The moving reaction force of the revolving roof 5 acting in one direction is received. As a result, the swivel roof 4 is swiveled around the swivel shaft 6 so as to overlap the swivel roof 5 with the swivel movement of the swivel roof 5.

Thus, as shown in FIGS. 2 to 3, the revolving roof 5 and the revolving roof 4 are finally overlapped on the fixed roof 3 to open the circular top surface surrounded by the outer peripheral wall 2.

At that time, the guide track 9 and the restraint guide rail 13 have a structure for receiving the reaction force for converting the force of the rotating roofs 4 and 4 pressing each other adjacent to each other into the rotating motion of the rotating roof 4.
This is as shown in FIG.

That is, since the guide track 9 and the restraint guide rail 13 have the same structure, the restraint guide rail 13 is shown in FIG. 4 for explanation.

The dolly 12 is swingably mounted on the rear surface of the rotating roof 4 with a shaft 16, and rails 17 are laid on the bottom surface and both side surfaces of a groove formed in a rectangular cross section on the surface of the slewing roof 5, so that the dolly 12 travels. The wheel 18 travels on the rail 17 on the bottom of the groove, and the wheels of the side pressure bearings horizontally projecting on both sides of the bogie frame come in contact with the rail 17a laid on the side surface of the groove and hit the rail 17a. A side pressure receiving wheel, which is referred to as a side pressure receiving wheel 19, is configured so that the side pressure receiving wheel 19 completely prevents lateral vibration of the carriage 12.

Therefore, when the revolving roof 5 moves on the revolving rail 7 along the circumferential direction of the outer peripheral wall 2, the revolving roof 4 receives a reaction reaction force received on the guide track 9 and the trolley 12 moves in the axial direction. The force acting in the direction traversing is restricted by the restraint guide rails 13, and the rotating shaft 6 and the restraint guide rails 13 prevent the bending deformation of the rotating roof 4.

<Effect> As described in detail above, according to the retractable roof of the present invention, a substantially crescent-shaped fixed roof is configured at one end of the substantially circular opening top surface, and the other portions have a diameter of the opening top surface. Two roof members that overlap each other on both sides of the line segment are formed, and the roof member on the outside of these two roof members is a swivel roof that swivels along the circumferential direction of the opening top surface, and the roof on the inside The member is a rotating roof that moves by receiving the reaction force of the rotating roof. The overlapping edge portions of the rotating roof and the rotating roof are rotatably connected to each other by a rotating shaft, and the rotating shaft is rotated. Restraint guide rails along the turning trajectory when the swivel roof overlaps the swivel roof as a center of movement are laid in a large groove formed in the swivel roof, and the bottom and side of this groove form Since the movement in the rotational movement direction is restricted, the top surface of the opening must be rotated. The swivel and swivel roofs can be moved simultaneously without the need for beams to support the swivel and swivel roofs. Therefore, there is an effect that the open feeling is excellent and the opening and closing time can be shortened.

Furthermore, since the position of the traveling carriage running inside the constraint guide rail can be kept constant by the rotation shaft and the constraint guide rail, that is, the vehicle travels in the constraint guide rail from the rotation axis of the rotating roof. Since the separation distance to the trolley can be kept constant, there is an effect that the bending deformation of the rotating roof can be prevented.
