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 open / close type membrane roof structure filed in the patent application is provided with arch-shaped guide rails (main rails) arranged parallel to each other, and provided on the guide rails so as to be able to run freely and successively. An opening / closing roof comprising a plurality of roof units, wherein each of the roof units has a substantially triangular cross-sectional view and a frame extending between the guide rails, and a membrane material stretched over the frame. , The frame frame is configured to be openable and closable with the top of the frame frame as a fulcrum, and the film material is provided and stretched by being provided between the pair of openable and closed frames. Thereby, it is constituted by a plurality of connecting members that open and close the opening and closing frame.

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] The folding means is to bend the hinge portion of the connecting member of the roof unit sequentially by protruding and retracting from the guide rail. In the folding means, the roof unit is opened when the roof is opened. When the connecting member is moved to the roof storage portion side and the connecting member is located above the folding means, the connecting member projects from the guide rail and pushes the hinge portion of the connecting member upward to fold the connecting member from the hinge portion. Bending, then buried in the guide rails, and sequentially repeating the process of waiting in the buried state until the next roof unit moves, repeatedly bending the connecting material of each roof unit It is supposed to.

[0007]

By the way, in the opening and closing type membrane roof structure having the above-mentioned structure, the connecting member of the frame of the roof unit is bent by bending means configured to be protruded and retracted from the guide rail. Therefore, it is difficult to set the timing of the emergence of the folding means in correspondence with the moving speed of the roof unit.For example, when the roof unit stops halfway for some reason, the timing of the emergence is out of order. As a result, there is a possibility that a problem such as the bending means hitting the moving roof unit may occur.

Further, when a compressive force is applied to the connecting member for some reason while the roof unit is running, the connecting member may be suddenly bent, which may hinder the running.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to reliably bend a connecting member supporting a frame of a roof unit in an open state at a predetermined position, and to connect the connecting member during traveling. It is an object of the present invention to provide an opening / closing mechanism for an opening / closing type membrane roof capable of preventing bending of a material.

Since the member is moved by the rolling of the wheel in the guide groove, the movement of the guide member is smooth, and eventually the movement of the roof unit is smooth. In addition, even if a compressive force acts on the connecting member for some reason and the connecting member tries to bend from the second hinge portion, the upward movement of the second hinge portion causes the wheel to move to the regulating portion. The guide member moves smoothly in the guide groove because it is regulated by rolling in contact, so that the roof unit can run on the main rail stably without being folded. it can.

According to a fourth aspect of the present invention, there is provided an opening / closing mechanism for an opening / closing type membrane roof according to any one of the first to third aspects, wherein a guide rail is disposed above the main rail, and the guide rail is provided on the top of the frame. A first guide rail portion provided so that the provided support portion can run freely, and the guide rail is provided so as to gradually rise toward a base end side; and a base end portion of the first guide rail portion. And the second guide rail portion which is provided continuously to the main rail and which is parallel to and separated from the main rail. Therefore, when the support portion shifts from the first guide rail portion to the second guide rail portion, the roof unit is It moves on the main rail in a state of being folded up and standing, but the upper end of the frame frame of the roof unit is supported by the support section running on the second guide rail section. Because is it drop is restricted, it can be run in a stable state without opening the roof unit.

According to a fifth aspect of the present invention, there is provided an opening / closing mechanism for an opening / closing type membrane roof according to any one of the first to fourth aspects, wherein the second hinge portion of the connecting member is connected to 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 hinge portions, the second hinge is formed when a compressive force is applied to the connecting member from an opening / closing frame. The part moves slightly downward, and the linking material is slightly bent downward from the second hinge part and held in a stretched state.
The opening / closing frame can be kept open.

Therefore, when each roof unit travels on the main 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 pulling force acts on each roof unit, the opening and closing frame is opposed to the pulling 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 in an open state at a predetermined angle, so that the vehicle can be stably driven with the opening / closing frame kept open.
