Description

[Detailed description of the invention] (Technical field to which the invention belongs) The present invention relates to a device for shielding an opening of a curtain structure.

(Problems with the invention and its features) The curtain structure, which is made by attaching the curtain to a frame made of shaped steel or pipes, is simple and inexpensive, so it can be used for the hood of a freight vehicle, Widely used in small tents and large tents such as gymnasiums and warehouses, these tent structures usually have a structure that is designed to create a comfortable environment for the objects and living things stored inside, including humans. A ventilation opening is provided, and a shielding curtain covering this opening is rolled up at any time to provide ventilation and allow light to enter the interior.

The present invention is designed to ensure that the opening is shielded by the shielding curtain, and that the shielding curtain is neatly stored in a shielding curtain storage box located on one side of the opening. The purpose of this device is to provide a shielding device for the opening of a curtain structure that allows light to enter the interior even when the curtain is closed, and its structural features are within the scope of the utility model registration claim. As described.

(Specific explanation of the invention based on drawings) In the drawings showing an embodiment of the invention, 1 is a frame material made of shaped steel, 2 is a curtain attached to the frame material 1, and 3 is a rectangular shape bored in the curtain 2. The upper and lower sides and one side of the opening 3 are provided with one tooth row 4, 5, and one of the slide fasteners, respectively.
6 is fixed.

7 is a vertically long shielding storage box attached to the frame material 1 on one side of the opening 3 (on the side opposite to the side to which the tooth row 6 is fixed); A slit 9 is formed through which the shielding curtain 8 passes.
A screen winding shaft 10 to which one end of the screen 8 is fixed is installed in the center of the screen storage box 7, and one end (lower end in the figure) that protrudes from the screen storage box 7. A rotating handle 11 is attached to the.

The shielding curtain 8 is provided with a transparent part 12 for lighting, and the three free sides of the shielding curtain 8 are provided with tooth rows 4', which engage with the tooth rows 4, 5, and 6 of the opening 3, respectively.
5' and 6' are fixed.

In the above device for shielding the opening of the curtain structure, when the opening 3 is to be shielded with the shielding curtain 8, the opening 3 is covered with the shielding curtain 8 pulled out laterally from the shielding curtain storage box 7, and the opening 3 is 3 side tooth rows 4, 5, 6
The mating teeth 4', 5', and 6' on the three free sides of the shielding curtain 8 may be engaged with each other to close the seams between the opening 3 and each of the three sides of the shielding curtain 8. 3
To open the screen, the slide fasteners on the three sides are unlatched, the rotation handle 11 is operated, and the screen 8 is rolled into the screen storage box 7.

In addition, an electric motor and a spring are attached to the shielding curtain winding shaft 10 instead of the rotating handle 11,
The shielding curtain 8 may be wound up using the power of an electric motor or the restoring force of a spring.

(Effect of the invention) Since the device for shielding the opening of the curtain structure of the present invention is as described above, in case of rain, the opening can be covered with a shielding curtain pulled out to the side from the shielding curtain storage box. By closing the joints on each three sides of the shielding curtain and the opening with slide fasteners, you can reliably prevent wind and rain from entering.Furthermore, since the shielding curtain has a transparent part to let in light, the opening can be shielded. Even when the curtain is closed, light still enters the structure, and on sunny days, the curtain can be neatly stored in the shield storage box located on the side of the opening to improve ventilation. With,
Light can enter the interior through the opening.
