It is designed to be freely supported and to hold and store the panel
You. [0003] SUMMARY OF THE INVENTION Such a conventional panel
With the shutter system, the storage
Panel storage operation to the
Make the panel pull-out operation between the drains always smooth
It is difficult to obtain smooth operation of such panels
Requires a very complicated panel drive
There was a problem. [0004] In particular, it is drawn out and deployed between the two guide rails.
The panel with the shutter closed is placed in the upper storage box
When retracted, it engages with the panel drive sprocket.
Roller chain and connected to both guide rails
Both ends are engaged freely to move up and down, and move up along the guide rail.
The ascending and descending panels are folded up during the ascending process.
The panel may become stuck due to
You. In this case, if left as it is, the roller chain
Is engaged with the panel drive sprocket.
Therefore, the panel drive sprocket and roller chain
And cause a major accident such as the panel being destroyed
There was a problem. It should be noted that a conventional shutter device of this type is
For example, in the specification of West German Patent Publication No.
There is one that has been disclosed, this shutter device,

Storage rails must be arranged so that they do not
No, for that, the bracket on both sides of the storage box
For hanging the roller chain between the storage rail
Spatial areas must be particularly reserved, and
Structure becomes complicated and the storage box becomes large,
There were issues such as the inability to make a compact fit structure. The present invention has been made to solve the above problems.
Mesh with the panel drive sprocket
The upper and lower guides to move up and down between the left and right guide rails.
The chain supporting the panel is

This allows the panel storage to be smaller and more compact.
It is possible to make a compact fit structure, and in the process of moving the panel
Moves the chain against the panel drive sprocket.
It can be smoothly meshed or unmated, and the panel drive
Prevent irregular engagement of the chain with the driving sprocket
Panel lifting operation always smoothly
Reliable panel type that can be performed efficiently
It is an object of the present invention to provide a shutter device. [0008] Means for Solving the Problems According to the invention of claim 1

Installation space can be minimized. Follow
Therefore, the installation space does not need to be particularly large.
The switchgear 13 is external to the storage box 5
Installation space for the storage box 5 is reduced
However, the restrictions on the installation work can be greatly eased. The storage tray in the storage box 5
At a position above and above the storage rail 4,
A chain tip guide rod 6 is arranged. This chain ahead
The end guide rod 6 is provided on both sides of the panel 2 suspended on the storage rail 4.
The upper space between the side end surface and the bracket 5a is effectively used.
It is arranged for use. The chain guide rod 6 has a panel

When the upper end of the motor reaches the panel driving sprocket 8,
The upper end of the panel 2 is a panel drive spur together with the chain 3.
A circular motion is made along the pitch circumference of the ket 8, and the storage rail 4
Is guided in the direction of. At this time, the panel roller 2 below the panel 2

Move into the storage box 5. Then, it is first shifted onto the storage rail 4.
The hanging roller 25 of the panel 2 is tilted downward of the storage rail 4.
When it reaches the lower end, the suspension roller 25 is retracted.
The stopper 4a provided at the lower end of the delivery rail 4
As a result, dropping from the storage rail 4 is prevented. Thus, the lower end of the storage rail 4 is lowered.
After the first panel 2 arrives at the section, the subsequent panels 2
