DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather baseball stadium, a baseball stadium, and other openable roofs of buildings having a large frame space.

[0002]

2. Description of the Related Art A vertically movable movable roof having a movable roof that moves up and down is disadvantageous in terms of a moving power capacity and a brake system, so that each movable roof 1, 1a is horizontally constructed as shown in FIG. The horizontal movement type is common. In this case, since the support surface is horizontal, spontaneous fall hardly occurs, and there is an advantage that the configuration of the brake mechanism, the brake capacity, and the power capacity can be reduced. Such a horizontally movable movable roof 1, 1a is generally constructed by looping a wire 3 for movement around each roof 1, 1a.

[0003]

However, in the case of a horizontal movable roof, the structural rigidity is low and it is necessary to reinforce it.
Therefore, a moving roof is often used in which the roof is assembled in an arch shape and only the moving supporting surface is horizontal. On the other hand, at the position where the movable roof is stacked and stored, the cross section of the entire movable roof becomes large, and there is a problem that the structural resistance is imposed on the roof floating countermeasures due to wind resistance as well as aesthetic appearance .

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vertically movable open / close roof capable of reducing power capacity and brake capacity.

[0005]

SUMMARY OF THE INVENTION To achieve the above objects, the retractable roof of the present invention moves at least symmetrically between an upper closed position and a lower open position along opposing slopes. In a retractable roof having a pair of movable roofs, one end of a wire is connected to a lower end of the one movable roof, and the wire is wound around a sheave arranged below the movable roof in an open position, and the other end is wound. It is characterized by being connected to the upper end of the other movable roof.

[0006]

[Effect] A pair of movable roofs is one roof (falling force)
The weight is offset by the weight of the other roof via wires. Therefore, the braking force when the roof is opened is reduced, and the roof can be opened with a small power capacity. In this case, it moves symmetrically between the upper closed position and the lower open position along the opposing inclined surfaces. Also, a pair of movable roofs can be moved synchronously and symmetrically by transmitting power to one location of the wire instead of to each separate power shaft.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention, in which an openable and closable roof extends along an inclined surface of a guide rail 5 erected in an arch shape between left and right outer walls 10 and 10, and the outer walls 10 and 1.
At least one pair of movable roofs 9 and 9a further extends outside the fixed roofs 7 and 7a integrally provided so as to cover the upper part of the central space from 0. The upper closed position (see FIG. 1) and the lower open position. Are configured to move symmetrically in the direction shown by the arrow. Thus, the movable roofs 9 and 9a can be opened and closed in an arch shape.

A wire 1 is provided at the lower end of one moving roof 9.
1 is connected to the outer wall 10,1.
0 and the fixed roof 7, 7a (located below the movable roof 9 in the open position) and a rotatable sheave 13,
13 and a plurality of rotatable sheaves 1 whose other ends are disposed below and near the top of the guide rail 5.
It is connected to the upper end of the other movable roof 9a via 3,13.

In this case, the wire 11 itself may be used as a pulling wire for the movable roof 9, 9a, or the movable roof 9, 9a may be used.
A truck supporting 9a on the guide rail 5 may be a power truck. The wire 11 is connected from the lower end of the movable roof 9 (fixed roof 7 side) to the upper end of the movable roof 9a on the opposite surface side (center opening side) through the back of each roof, and further from the lower end of the movable roof 9a. It is connected to the upper end of the movable roof 9 on the opposite side so as to pass through the backs of the fixed roof 7 and the movable roof 9a. A guide wheel (sheave) 13 for the wire 11 is provided on the back surface of each roof 7, 9, 9a. When one movable roof 9 is lowered and opened, the wire 11 at the lower end is loosened, and at the same time, the movable roof 9a at the opposite position is also lowered and the wire 11 is pulled. Thus, the falling load of one moving roof 9a is
In order to cancel each other, the opposing surfaces of the opposing roofs 9 and 9a are directly connected to each other with a wire 11 so that the weights of the right and left roofs 9 and 9a are balanced. It has become. Therefore, the braking force and power of the roofs 9 and 9a can be set small.

[0010]

As described in detail above, according to the openable roof according to the present invention, at least a pair of roofs that move up and down symmetrically are connected so that the wires are inverted and crossed midway. As a result, the falling loads of both moving roofs are balanced, and the brake capacity for drop prevention can be made significantly smaller than that of a normal up-down openable roof. As a result, the adoption of a vertically openable roof can be facilitated, the reinforcement of the roof structure of the movable roof can be reduced, and the storage vertical cross-sectional area can be reduced, so that the moving power capacity can be reduced reflectively.
