DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door closing device for a simple door used for opening and closing a partition, a lightweight door, a curtain, and the like provided in a private room entrance and a passage in a building.

[0002]

2. Description of the Related Art There are large door checks using cranks, springs, etc. that automatically close heavy doors for entrances and entrances, but there is no lightweight simple door in the room.
At present, the use is slightly increased by using a coil spring, a flat rubber cord, or the like. However, since these are pulled from a place away from the door portion, there is a problem in an attachment place.

[0003]

SUMMARY OF THE INVENTION It is desired to eliminate privacy problems due to forgetting to fasten indoor entrances, doors and curtains for partitioning aisles, and to reduce the effects of cooling and heating.

[0004]

Means for Solving the Problems A square spring stopper (4) having two dovetail grooves, protruding from the center of one side shell of the main body case (1), and combining two square half shells made of synthetic resin. The spiral spring (2) is locked, built into the drum (3), rotatably fitted therein, and connected so as to be able to take up a 1.5-2.0 rice length required for opening and closing the door, and a main body case ( At the end of the rope (6) pulled out from the entrance (9) of the round hole provided at the upper end of 1),
A clip (5) having a connection hole (10) is connected, and a hinge (8) for horizontally rotating the door (9) side of the main body case (1) is integrally formed on the opposite side of the door (9). Simple door automatic closure.

The main body case (1) is provided with a band through hole (7) for fixing the same to the curtain rail, or a horizontally long penetrating band through hole (7) is provided on the upper surface of the main body case (1). Simple door automatic closure.

BEST MODE FOR CARRYING OUT THE INVENTION In the case of a simple door for a room partition, a washroom, a toilet, etc., a threaded hook is screwed into an upper end of an opening side of the door. On the surface, fix the hinge type mounting part with wood screws so that the rope entrance of the main body case is on the top side, pull out the rope, connect it to the threaded hook attached to the upper end of the door, and connect it to the connection hole provided on the clip When the door is pushed open, the rope is pulled out in accordance with the circular motion of the door, the spiral spring is charged and pulled out, and when the hand is released, the rope is rewound into the main body case by the stored force of the spiral spring, The connecting door automatically closes, and the circular movement of the door that opens and closes corresponds to the horizontal rotation of the hinged mounting part, which opens and closes comfortably. This simple automatic closure can be used for the door of the dog in and out of the room

When used for opening and closing a curtain, a rope is wound around a band through a band passing hole so that the rope entrance and exit of the main body case are on the outside of a fastener at one end of a curtain rail, and a rope is fixed from the main body case. Pull out and connect the upper end of the curtain with a clip. When the curtain is pulled, the spiral spring is stored and pulled out, and when you release your hand, the rope is wound into the main body case by the stored force of the spiral spring, The curtain locks automatically.

[0008]

According to the present invention, since the door is automatically closed, the door is not left open, privacy is protected, and the cooling / heating effect is not impaired.
