Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stop device including a main body attached to a door, a wall or a floor, and a receiving member with which the main body abuts. More specifically, the present invention relates to a door stop device using a magnet. .

[0002]

2. Description of the Related Art Conventionally, a general door-stopping device is a device for absorbing a shock between a door that is opened and closed and a wall, and for locking an opened door on the wall side. Is used.

The door locking means using the latch has a trouble that a user bends to hang or remove the latch, and in order to eliminate the trouble, the door is wall-sided with a single touch using a magnet. A variety of door-stopping devices called magnetic catches that are held in the air have been proposed.

As a door stopper using a magnet, for example, in Japanese Utility Model Laid-Open No. 2-137473, a magnet is attached to the tip of a door stopper main body fixed to the door side, and is attached to a wall side with which the main body abuts. A door stop device is disclosed in which at least part of the body is made of iron.

In a door equipped with a door stop device using this magnet, when the door is opened and the tip of the door stop main body is brought into contact with a receiving body mounted on a wall, the main body and the receiving body are magnetically attracted to each other. The open state is automatically maintained. Most door-stopping devices using magnets basically have a structure in which an open door is simply locked to the wall side by the magnetic attraction force of the magnets.

[0006]

However, a door equipped with a conventional door-stopping device using a magnet does not need to be attached to the wall when the door is fully opened to the wall. It is automatically magnetically attracted and is kept in a hooked state. When closing the door, the door must be pulled against the magnetic attraction force, and when closing the magnetically attracted door, the weak children and the elderly are burdensome and difficult to handle. There is.

The present invention has been made in view of the above problems. When the door need not be attached to the wall side,
The object is to make the door stop device easy to handle using a magnet that does not exert a magnetic attraction force.

[0008]

The present invention provides a door stop device comprising a rod-shaped main body having a magnet at its tip and a receiver having a magnet to which the tip of the main body abuts and attracts. Each magnet has an NS double magnetized surface on each front end surface thereof, and is rotatably mounted around an axis to which at least one magnet of each magnet is attached, and is rotatable. By rotating the magnet,
Set the magnetic poles of the magnetized surfaces of the abutting magnets to different poles to lock the door to the wall side by magnetic attraction, and set the same pole to repel each magnetized surface to free the door. I decided to.

Further, the front end surface of each magnet is covered with a cover, and a display for recognizing the NS both magnetized surfaces is provided on the front end surface of each cover. It is now possible to switch between the same and different polarities of the magnetic surface.
