Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ceiling storage type shutter, and particularly to a closing device thereof.

[Conventional technology]

Conventionally, ceiling-mounted shutters, in which a shutter consisting of multiple shutter panels connected vertically, is stored in the ceiling along guide rails erected on both sides of the opening, or lowered to open and close the opening. A rope is attached to the lowest shutter panel, and to close the open shutter, manually pull down the rope hanging from the raised lowest shutter panel to lower the shutter. It's becoming like that.

[Problem that the invention attempts to solve]

However, since the tip of the rope is simply fixed at a suitable height on one side of the opening, the rope that comes down as the shutter panel descends may drip onto the floor and become dirty. There was an inconvenience that the shutter could not be closed completely because it was caught between the lower end of the shutter and the floor.

The present invention was devised to eliminate the above-mentioned conventional inconveniences, and its purpose is that when closing a ceiling-storage type shutter, the pulling rope that hangs down as the shutter descends will drop to the floor. To provide a closing device for a ceiling storage type shutter, which prevents the shutter from dripping and becoming dirty, or from being caught between the lower end of the shutter and the floor, preventing the shutter from being completely closed.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention involves sending a shutter consisting of a plurality of shutter panels connected vertically into the ceiling along guide rails erected on both sides of the opening, opening the opening, and removing the shutter from the bottom. In ceiling storage type shutters, the rope attached to the lowermost shutter panel is pulled down to lower the shutter and close the opening.
A rope with a length of about 2/3 of the effective opening height of the shutter is attached to the side, while a rope with a length of about 2/3 of the effective opening height of the shutter is attached at a height of about 1/3 of the effective opening height of the shutter on the rope attachment side of the opening. An eye fitting is disposed in the rope, and the free end of the rope is inserted through the eye fitting.

[Effect]

Therefore, in the ceiling storage type shutter closing device according to the present invention, when the fully open shutter is pulled down by 1/3, the tip of the rope reaches the floor, and when the shutter is pulled down further, the rope hangs down from the eye fitting in a U-shape. When the shutter is fully closed, the rope hangs from the eye fitting at the midpoint of its length, preventing it from dripping to the floor.

〔Example〕

The present invention will be explained in detail below based on an illustrated embodiment.

1 to 4 are side views showing the state in which the ceiling-storable shutter 1 is gradually lowered from fully open (Fig. 1) to fully closed (Fig. 4). Long shutter panels 2 are connected vertically, and each shutter panel 2 has an opening 4 through rollers 3 attached to both sides.
It is supported by guide rails 5 erected on both sides. The guide rail 5 is curved in the horizontal direction above the opening 4 to follow the ceiling 6, and a stopper 7 is provided at the end.

A long shaft 8 is installed above the opening 4 in the direction of the entrance, and the end of a wire (not shown) wound around a wire drum 9 fixed to the shaft 8 connects to the lowermost shutter panel. 2', and the wire drum 9 is constantly attached to the shutter panel in order to balance the weight of the shutter panel 2 on the vertical part of the guide rail 5 by means of a balance spring (not shown) wound around the shaft 8. 2 in the upward direction.

One end of a rope 10 having a length of about 1/3 or more of the effective opening height H when the shutter is fully opened is attached to one side of the lowermost shutter panel 2. On the other hand opening 4
On the attachment side of the rope 10, an eye fitting 12 as shown in FIG.
The free end of the rope 10 is inserted through the rope 10, and a weight 11 is fixed to the lower end of the rope 10.

In the above configuration, when the shutter 1 is fully opened, the shutter panel 2 is stored almost parallel to the ceiling 6 along the guide rail 5 as shown in FIG. is set to a little over 2/3H, and the height of the eye fitting 12 is 1/3H, so the lower end of the rope 10 is located almost directly below the eye fitting 12.

Next, pull down the rope 10 and lower the lower end of the shutter to a height of about 2/3H above the floor as shown in Figure 2. Since the rope length is about 2/3H, the weight 11 at the lower end of the rope 10 almost reaches the floor.

If you can reach the shutter at this point, hold it and lower it further, but at this time, make sure that the extra length of the rope 10 does not hang down inside the eye 12'.
The extra length of 0 is guided to the outside of the eye 12'. and the third
As shown in the diagram, place the lower end of the shutter approximately 1/3 above the floor.
When lowered to the height H, the lower end of the shutter reaches exactly the position of the eye fitting 12 and the rope 10
The extra length of approximately 1/3H of the length hangs down from the eye fitting 12 in a U-shape of approximately 1/2 of the length.

Finally, when the shutter is fully closed, the rope 10 forms an inverted U-shape with the midpoint of approximately 2/3H of its total length suspended from the eye fitting 12, as shown in Fig. 4, and the rope 10 drops to the floor. can avoid.

[Effect of idea]

As described in detail above, according to the present invention, in a ceiling storage type shutter, one side of the lowest shutter panel is provided with approximately 2/2 of the effective opening height of the shutter.
While attaching a rope with a length of 3 or more, an eye fitting is provided at a height position of about 1/3 of the effective opening height of the shutter on the rope attachment side of the opening, and the eye fitting is provided with the above-mentioned rope. Because we inserted the free end of the rope,
When closing the shutter, the slack rope that hangs down as the shutter descends may drip onto the floor and get dirty, or it may get caught between the lower end of the shutter and the floor, preventing the shutter from closing completely. The disadvantages are completely eliminated, and since the device is extremely simple, the cost required for it is extremely low.

The drawings show one embodiment of the present invention. Figure 1 shows the shutter fully open, Figure 2 shows the shutter lowered by 1/3 of the effective opening height, and Figure 3 shows the same 2/3.
