Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a panel shutter device for opening and closing a shutter opening / closing opening such as a doorway or a window of a building by a plurality of connecting panels.

[Conventional technology]

FIG. 9 is a cross-sectional view of a panel storage box in a conventional panel shutter device, and in the figure, 1 is a pair of left and right vertical guide rails which are arranged on both sides of a shutter opening / closing opening such as an entrance / exit of a building or a window to stand up. A box 2 for storing a panel is arranged above the guide rail 1.

In the box 2, a sprocket 3 for vertically driving the panel located above the doorway is arranged, and the sprocket 3 is driven by the panel opening / closing drive means M through a speed reducer or the like to rotate in the forward and reverse directions. Has become.

A pair of left and right chains 4 that move up and down along the upper guide rail 1 mesh with the sprocket 3.

The chain 4 connects upper and lower panels 5 vertically adjacent to each other between the guide rails 1 in a bendable manner.

Each of these panels 5 has an upper guide roller 6 on the upper side of each side, and these upper guide rollers 6 are vertically engaged with the guide rail 1 and are arranged on the upper portion of the box 2. It is possible to move onto the support rail 7.

The support rail 7 is arranged in the box 2 in an inclined state in which it gradually descends in a direction away from the vicinity of the sprocket 3.

Next, the operation will be described. When the shutter is used in which the panel 5 is extended between the left and right guide rails 1, when the panel opening / closing drive means M is activated to store the panel 5 in the box 2, the sprocket 3 is rotationally driven in the arrow direction. As the chain 4 meshing with the sprocket 3 moves up along the guide rail 1, the panel 5 comes into the box 2.

Then, when the upper guide roller 6 of the panel 5 passes through the sprocket 3 and moves onto the support rail 7, the upper guide roller 6 is inclined due to the inclination of the support rail 7, and the upper guide roller 6 is urged by the weight of the panel 5. Support rail 7
Rolling down. Therefore, the plurality of panels 5 that have entered the box 2 as described above are stored in the box 2 by being suspended by the support rails 7 in a parallel folded state in which the panels 5 are adjacent to each other in a vertical posture.

Further, when the panel opening / closing drive means M is reversely activated from such a panel stored state, the sprocket 3 is driven in the direction opposite to the arrow, so that the respective panels 5 suspended by the support rails 7 are chained. Guide rail 1 through 4
To the shutter closing position.

[Problems to be solved by the device]

The conventional panel shutter device is configured as described above,
Since the support rails 7 that suspend the panels 5 that have entered the box 2 in the parallel fold state while maintaining their vertical postures are inclined, the inclination amount Δh corresponds to the height h of the panel 5 alone. The height Δh + h of the box 2 must be taken into consideration, which causes a problem that the height dimension of the box 2 must be increased.

When the height of the box is increased in this way, if the panel shutter device is stored inside the ceiling at a store, etc., the ceiling will be lowered due to the panel storage space, and the opening height of the entrance / exit will be restricted. There are problems that the location is limited, and the aesthetic appearance of the entire shutter device is impaired.

If the support rail 7 of the conventional panel shutter device is arranged horizontally, the box height can be reduced by Δh. However, if the support rails 7 are simply horizontal, when the panel 5 is stored in the box 2,
Is stopped at a position immediately after passing through the sprocket 3, and when the next rising panel 5 swings while passing through the sprocket 3, the panel 5 collides with the stopped panel 5. It causes a problem that it causes a problem in operation.

This invention has been made in order to solve the above-mentioned problems, and the height dimension of the panel storage box can be reduced by the above-mentioned Δh without changing the height dimension of each panel. It is an object of the present invention to provide a panel shutter device capable of smoothly accommodating the panel and unwinding the accommodating panel.

[Means for Solving the Problems]

The panel shutter device according to the present invention includes a panel storage box, a panel longitudinal drive sprocket that vertically drives a plurality of panels connected in a chain, and a panel horizontal drive panel. The sprocket is installed, and the support rails that are driven by these sprockets to suspend the plurality of panels that have entered the box in the adjacent hanging state are arranged horizontally on the panel storage direction side of the panel lateral drive sprocket. It was done.

At this time, it is preferable to dispose the guide plate of the upper chain along the upper portion between the two sprockets.

[Action]

In the panel shutter device according to the present invention, the panel that has been vertically driven into the box by being driven by the sprocket for driving the panel in the vertical direction is continuously driven by the sprocket for driving in the lateral direction of the panel so that the panel is housed in the box in a fixed direction. Distance Forcibly feeds horizontally and then hangs adjacent to a horizontal support rail.

At this time, since the support rails for suspending the panels are horizontally arranged in the panel storage box, the height of the box is increased by an amount corresponding to the inclination as compared with the conventional case in which the support rails are inclined. The size can be reduced. Therefore, for example, when the shutter device is stored in the ceiling in a store,
Even when it is installed in a place where the ceiling is low, the opening height of the entrance / exit is not restricted, and the aesthetic appearance of the entire shutter device is improved.

Moreover, since the panel is forcibly fed horizontally for a certain distance in the panel storage direction or the panel delivery direction between the sprocket for driving the panel vertical direction and the sprocket for driving the panel horizontal direction, for example, the panel is stored in a box. In such a case, the panel can be stopped after passing through the sprocket for driving the panel in the vertical direction and then at a position separated from the sprocket by a predetermined distance or more in the panel storage direction. Even when the panel swings while passing through the sprocket, the panel does not collide with the stopped panel. Therefore, the panel can be smoothly stored in the box and the storage panel can be unwound.

The chain is guided by the guide plate and can be smoothly moved between the two sprockets.
