DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing mechanism for an openable / closable membrane roof which can open and close the roof of athletic facilities such as baseball and soccer or other large-scale facilities according to the weather or the like.

[0002]

2. Description of the Related Art In recent years, for indoor athletic facilities and the like,
Large fixed dome roofs have been adopted. As a structure type of the fixed dome type roof, a steel truss structure using a single-layer truss or a multi-layer truss, a cable structure, and a structure combining these steel truss structure and cable structure are known. In such a fixed dome type roof, there is a roof having a membrane structure by a method in which a roof finishing material such as a metal plate is attached to the steel truss or a membrane expanded by filling with air is pressed by a cable structure.

By the way, even if the fixed dome roof has a membrane structure, it cannot be denied that the roof has a closed atmosphere. For this reason, in recent years, an open / close type membrane roof structure is being developed, and the present applicant has previously filed a patent application for the technology of the open / close type membrane roof structure (Japanese Patent Application No. 7-4).
342).

[0004] The technology of the openable-type membrane roof structure filed by the patent is based on arch-shaped guide rails arranged in parallel with each other, and a plurality of roof units provided on the guide rails so as to run freely and successively. With an opening and closing roof consisting of
Each of the roof units is formed of a frame having a substantially triangular cross section and extending between the guide rails, and a film material stretched over the frame, wherein the frame is a top portion of the frame. A pair of opening / closing frames, each of which is configured to be openable and closable with a fulcrum, and the membrane material is stretched, and a connecting member that is provided between these opening / closing frames and extended to openably close the opening / closing frame. It is composed.

In the open / close type membrane roof structure having the above structure, the roof is opened and closed by running a plurality of roof units along guide rails.
By moving each roof unit and sequentially bending the connecting members of the frame at predetermined positions by bending means, these roof units are sequentially folded.

[0006]

By the way, in the opening and closing type membrane roof structure having the above structure, when the roof is opened,
It is necessary to close the opening / closing frame and fold the roof unit while folding the connecting member. When closing the opening / closing frame, the traveling of the roof unit becomes unstable unless it is sequentially folded from the top roof unit in the moving direction, which is not preferable. It is more preferable from the viewpoint of running stability that the roof unit is folded when the preceding roof unit is folded and stopped at the end of the guide rail.

[0007] When the roof units are sequentially folded from the top, the connecting members of the roof units have a compressive force from the rear roof unit after the top roof unit stops at the end of the guide rail. Until each roof unit is folded, the ties must be stretched so that the open / close frame of the roof unit is kept open so that it is not folded in the center. There is. Furthermore, when the roof is closed, in order to keep the open / close frame of each roof unit open, the connecting member is stretched against a compressive force so that the connecting member is not folded at the center. There is a need.

The present invention has been made in view of the above circumstances, and is provided between opening and closing frames for opening and closing a roof unit, and is extended so that a connecting member for opening and closing the opening and closing frames can be freely opened and closed. An object of the present invention is to provide an opening / closing mechanism for an openable / closable membrane roof that can be securely stretched and that allows each roof unit to be sequentially folded from the top when the roof is opened.

[0009]

In order to achieve the above object, an opening and closing mechanism for an opening and closing type membrane roof according to the present invention comprises an arch-shaped guide rail arranged in parallel with each other, and In an openable / closable membrane roof comprising a plurality of roof units movably and sequentially provided on a rail by a traveling carriage, each of the roof units has a substantially triangular cross-sectional view and extends between the guide rails. A frame frame, and a film material stretched over the frame frame. The frame frame is configured to be openable and closable by rotating about the top of the frame frame as a fulcrum.

Further, the frame frame is connected to a frame frame adjacent thereto by connecting a lower end portion of each opening / closing frame to the traveling carriage so as to be rotatable, and the connecting member is constituted by a pair of arms. One end is rotatably connected to the opening / closing frame by a first hinge portion, and the other end portion of the arm is rotatably connected to each other by a second hinge portion. The arms are connected to each other so as to be eccentric to a position spaced downward from a straight line connecting the first hinge portions when the arms are extended on a straight line.

In the opening / closing mechanism of the opening / closing type membrane roof of the first aspect, one end of each arm constituting a connecting member connecting the opening / closing frames of each roof unit is turned to the first hinge portion by the opening / closing frame. Since the arms are movably connected to each other and are rotatably connected to each other by the second hinge, the first hinges come into contact with each other while each arm rotates upward and downward about the first hinge as a fulcrum. When the second hinge part moves upward, the connecting member is folded from the second hinge part to open and close the opening / closing unit, that is, each roof unit is opened and closed.

In a state where each roof unit is opened, the connecting member is extended because the opening / closing frame is open. However, the second hinge portion causes the first hinge when the connecting member is extended in a straight line. Since the arms are connected to each other so as to be eccentric to a position separated downward from a straight line connecting the hinges, the second hinge moves slightly downward when a compressive force is applied to the connecting member from the opening / closing frame. As a result, the connecting member is slightly bent downward from the second hinge portion and held in a stretched state, whereby the opening / closing frame can be held in an open state.

Therefore, when each roof unit travels on the guide rail, even if a compressive force acts on the open / close frame of the roof unit, the roof unit can be stably run with the open / close frame kept open. On the other hand, even if a tensile force acts on each roof unit, the opening / closing frame is opposed to the tensile force in a state where the second hinge part moves slightly upward and the connecting member is slightly bent upward from the second hinge part. Can be held open at a predetermined angle, so that the vehicle can be stably driven with the open / close frame kept open.

Then, together with the cantilever 42, one arm 17a of the connecting member 17 rotates upward with the first hinge portion 23 as a fulcrum, whereby the connecting member 17 is moved to the second hinge portion 24.
It is bent slightly upward from above. And
The frame 14 with the connecting member 17 bent is pressed by a frame 16 located on the right side thereof, and the pressing force causes the connecting member 17 to be folded as shown in FIG. , 16 are folded. 7 to 9, the arrow A indicates the traveling direction of the traveling vehicle 32.

As shown in FIG. 1 and FIG. 2, the open / close roof 1 is provided at both ends of the guide rails 10 and 10.
Roof storage portions 43, 43 for supporting and storing the 2, 2 in a folded state are provided to be supported by the keel arches 13, 13. The roof storage section 43 has a box shape extending between the guide rails 10, 10, and has a front surface serving as a storage port 43 a for storing the openable roof 12.
The wall opposing a supports the folded open / close roof from the rear side, thereby preventing the open / close roof 12 from falling down.

Further, on the guide rail 10 inside the roof storage section 43, as shown in FIG. 10, a top roof unit bending means 45 is provided. The top roof unit bending means 45 is a frame unit 14 of the top roof unit 11 that is first stored in the roof storage unit 43 among the roof units 11 that move toward the roof storage unit 43.
The second hinge portion 24 of the connecting member 17 is connected to the guide rail 1.
It is bent by appearing and disappearing from zero.

Then, the top roof unit bending means 4
5, when the roof is opened, the roof units 11 move into the roof storage section 43, and the top roof unit 1
When one connecting member 17 is located above the leading roof unit bending means 45, the connecting member 17 protrudes from the guide rail 10 and pushes up the second hinge portion 24 of the connecting member 17 so that the second connecting member 17 is in the second position. It is bent from the hinge part 24 and thereafter buried in the guide rail 10.

Next, a description will be given of a method of opening and closing the roof by the opening and closing mechanism in the opening and closing type membrane roof having the above configuration. (1) When the openable roofs 12 are opened: In this case, as shown in FIG. 11, the roof units 26 of the openable roofs 12 provided on both sides of the guide rail 10 , And are opened from the closed state.

First, after the roof units 26 are disconnected from each other, the drive cart 28 of the roof unit 26 is driven toward the end of the guide rail 10 so that the roof units 11 are connected by the roof unit 26. Press,
The roof units 11 are moved to the end of the guide rail 10. At this time, since the guide rail 10 has a downward slope, the roof units 11 move under their own weight, but when the moving speed needs to be adjusted, the drive cart 28 is driven in the opposite direction. I'll keep trying.

Then, when the top roof unit 11 moves into the roof storage section 43 and comes into contact with the end thereof and stops, the connecting member 17 of each roof unit 11 has its own weight and the direction opposite to the moving direction. A compressive force acts from the located roof units 11. Then, since the second hinge portion 24 is eccentric below the first hinge portion 23, the connecting member 17 is slightly bent downward from the second hinge portion 24 because the second hinge portion 24 moves slightly downward. It is held in a stretched state, whereby the openable frames 16, 16 of each roof unit 11 are held in an open state.

Next, the top roof unit bending means 4
5 is projected from the guide rail 10. Then, the linking member 17 of the roof unit 11 located at the upper side of the bending unit 45 is bent slightly upward from the second hinge portion 24 at the center thereof. After the connecting member 17 is bent, the leading roof unit bending means 45 is moved to the guide rail 10.
To be buried. Next, the roof unit 26 is moved by the drive cart 28 toward the roof storage section 33 by a predetermined pitch (a length substantially equal to the extended connecting member 17). Then, the top roof unit 11 is pushed by the end of the roof storage section 43, whereby the connecting member 17 of the roof unit 11 is further folded and folded, and the openable frames 16, 16 are folded.

As the top roof unit 11 is folded, as shown in FIG. 8, the connection between the top roof unit 11 and the roof unit 11 located to the right of the top roof unit 11 is supported. The pushing rod 36 provided on the traveling carriage 32 moves to the right roof unit 11 side by the moving mechanism 38, and the pushing rod 36 presses the cantilever 42. Then, together with the cantilever 42, one arm 17a of the connecting member 17 rotates upward about the first hinge portion 23 as a fulcrum, whereby the connecting member 17 is slightly bent upward from the second hinge portion 24. Further, the open / close frames 16, 16 of the right roof unit 11 are folded by the compressive force, that is, the roof unit 11 is folded. By repeating these steps sequentially, each roof unit 1
1 are sequentially folded from the top, and these roof units 11 are stored in the roof storage section 43. Finally, the roof storage section 43 is left with the roof unit 26 as it is.
(See FIG. 12).

If the openable roof is opened by the roof units 11 as described above, each roof unit 11
When the vehicle runs on zero, even if a compressive force acts on the open / close frames 16, 16 of the roof unit 11, the vehicle can be stably driven with the open / close frames 16, 16 kept open. In addition, since each roof unit 11 sequentially moving toward the end of the guide rail 10 can be folded when the preceding roof unit 11 is folded and stopped at the end of the guide rail 10, that is, When the roof unit 11 moves on the guide rail 10, the roof unit 11 runs in an open and stable state, and is sequentially folded at the end side of the guide rail 10. Can be stably stored in the roof storage portion 43 on the end side of. Further, since each roof unit 11 has an independent structure in which the film material 15 is stretched on itself, even if the opening / closing frames 16, 16 of a certain roof unit 11 cannot be opened / closed for some reason, Since the other roof units 11 function normally, opening and closing are not impossible at that time. Further, since each roof unit 11 has the film material 15 stretched on itself, the film material 15 does not flutter in any state of opening and closing the roof, and the film material 15 is stretched. Opening frame 1
6 and 16 become a stable triangular truss by extending the connecting member 17, so that when each roof unit 11 runs on the guide rail 10, it is always in a structurally stable state. Therefore, the roof can be opened and closed smoothly even if the roof is opened and closed by the wind or the like. Further, when each roof unit 11 travels on the guide rail 10, it is always in a structurally stable state, so that even if the roof unit 11 is stopped in the middle of the guide rail 10, it is structurally stable. Therefore, the roof unit 11 can be stopped in the middle of the guide rail 10, whereby the opening area of the roof can be easily adjusted. In addition, since the film material 15 is previously stretched on the opening / closing frames 16, 16, there is no need for a force to bend the film material 15 itself.
The roof can be opened and closed only by the power required to run the vehicle 1 on the guide rail, that is, only by the driving force of the driving carriage 28 provided on the front roof unit 26. Further, since the leading roof unit 26 that runs on the guide rail 10 in succession with the roof units 11 is substantially the same shape and rigid structure as the roof unit 11.
Is driven by the driving cart 28, the roof units 11 can be stably driven along the guide rails 10, and the opening and closing of the roof becomes smoother.

(2) When closing the open / close roofs 12, 12, first, the open / close roofs 12 stored in the respective roof storage sections 43
Of the roof unit 26 is moved by the driving carriage 28 toward the center of the guide rail 10 at a predetermined pitch. Then, the opening and closing frame 1 of the next roof unit 11 in the folded state
One of the sides 6, 6 is pulled by the roof unit 26, whereby the folded connecting member 17 is straightened to form one roof unit 11 having a structurally stable state and having a triangular cross-section in cross section. You. When a tensile force is applied to the connecting member 17 so as to extend straight from the folded state, the connecting member 17 is bent so that the second hinge portion 24 thereof is located slightly above,
In this state, a tensile force is applied.

Next, the roof unit 26 is further moved by a predetermined pitch, so that the next roof unit 11 is pulled out from the roof storage section 43 in the same manner as described above, and the roof unit 11 having a triangular cross section in cross section is moved. By repeatedly performing the forming step sequentially, as shown in FIG. 13, each roof unit 11 of the openable / closable roof 12 that has been folded and stored in the roof storage section 43 is drawn out while being formed in a triangular shape in cross section. go. Finally, the roof units 12, 12 of the respective roofs 12, 12 are connected at the center of the guide rail 10 to completely close the roofs 12, 12.

When the openable roof is closed by the above roof units 11..., When each roof unit 11 travels on the guide rail 10, a tensile force acts on the openable frames 16, 16 of the roof unit 11. Also, the vehicle can be stably driven with the openable frames 16, 16 kept open.
