Description: TECHNICAL FIELD The present invention relates to a shutter, and more specifically, to a shutter main body and a guide pillar that guides the shutter main body in a vertically slidable manner. The present invention relates to a shutter that is attached to a building so as to be movable laterally and provided with a moving device that moves and operates the guide pillar.

[Conventional technology]

Generally, in this kind of shutter, at the entrance of the building,
A plurality of shutter bodies are installed, and a guide pillar for guiding the shutter bodies in a vertically slidable manner is arranged between the pair of shutter bodies to open and close the shutter bodies.

In such a shutter, in the closed state, the guide pillar is arranged at a predetermined position of the entrance portion for guiding the shutter body, but in the open state, the guide pillar is provided on the wall surface portions on both sides of the building entrance. Some have been configured to move and use the entrance of a building widely.

The structure of such a shutter is shown in FIG. 9 (a) (in the figure, the position of each guide pillar in the shutter closed state is a solid line, and each guide pillar is moved to the maximum to open the entrance. The position of the guide pillar is indicated by an imaginary line.). In this example, a pair of guide columns is arranged between the three shutter bodies. And, conventionally, the guide pillar is configured to be movable in the lateral direction of the building entrance by the guide portion provided in the ceiling part, and to configure a moving device for moving the guide pillar. The chain is connected and the chain is rotated by a motor installed on the ceiling side.

There is no particular problem because it can be moved to the wall surface on both sides and the building entrance can be opened without obstruction. However, as shown in FIG. 9B, a problem arises when the number of shutter bodies is four or more.
That is, as shown in the figure (in the figure, the position of each guide pillar in the shutter closed state is a solid line, and the guide pillar position when the guide pillars are moved to the maximum and the entrance is opened. , The moving devices are arranged side by side in the lateral direction of the building entrance for each guide pillar. Therefore, the laterally movable distance of the guide pillar is substantially equal to the lateral width of the shutter body. It was impossible to open the entrance completely without any obstacles such as guide pillars when the shutter was open.

From the above situation, the object of the present invention is to eliminate the above-mentioned conventional drawbacks, and no matter how the number of shutter bodies is increased, all the columns are moved to one or both of both wall surfaces. It is to obtain a shutter having a configuration capable of.

[Means for Solving the Problems]

In the above, the moving device includes a guide rail provided over the moving range of the guide pillar, and a drive device that moves by being guided by the guide rail, and among the drive device and the guide rail. The guide rail is installed on the building side, and the drive unit is integrally attached to the guide pillar.

In constructing the moving device, the guide rail may be formed of a chain, and the driving device may be formed of a sprocket that meshes with the chain and a motor that drives the sprocket.

[Work]

 The operation by adopting the above configuration is as follows.

In the shutter having this structure, the guide rail is provided on the building side over the range of movement of the guide pillars, and the drive device is attached to each guide pillar and moves together with the guide pillars, that is, provided on each guide pillar. Since the drive device is configured so that the guide rail on the building side can be commonly used, the guide pillar can move along the guide rail over substantially the entire width of the building entrance.

〔The invention's effect〕

Therefore, the movable distance of each guide pillar is not limited to the width of the shutter body. As a result, no matter how the number of shutter bodies increases, the moving device installed on each pillar can be operated arbitrarily to place all the pillars on one or both of the wall surfaces at both lateral ends of the building entrance. It is possible to obtain shutters that can be transferred, and in a building with a large entrance, it is possible to easily open the building entrance greatly by using the driving force of the driving device.

Further, according to the configuration of claim 2, the chain, the sprocket, and the motor are used as the moving device, and while avoiding an increase in the weight of the guide column as much as possible, the rail laying can be easily and easily performed, and the movement as a whole can be performed. The structure of the device can be simplified.
