[0003]

However, in the case of the conventional door, the structure differs depending on whether it is front opening or rear opening and right opening or left opening. That is, the attachment positions of the door plate and the frame body are different depending on whether the door is open frontward or rearward, and the attachment positions of the stoppers of the door plate also differ. The structure on the left and right differs depending on whether it is right or left. There was no compatibility between the doors in each of these configurations.

For this reason, for example, when the door is opened in the front stage at the design stage, it is erroneously recognized as being opened backward by some mistake, and when the door is supplied to the construction site based on the mistake, the door is used as it is. I couldn't do that, and I had to prepare a new door with the original design. As a result, the work becomes inefficient.

The present invention has been made in view of the above-mentioned problems, and provides a door device which can be adjusted according to whether it is front opening or rear opening and right opening or left opening during assembly. The purpose is to

In order to solve the above-mentioned problems, the door device according to the first aspect of the present invention supports a door plate and the door plate so as to be rotatable, and does not open the closed door plate. In the door device including the frame body that is supported as described above, the door plate can be attached to the frame body in any state of front opening or rear opening and left opening or right opening.

A door device according to a second aspect of the present invention is a door device which is attached to any one side of the door plate and is locked to any one side of the frame body to rotatably support the door plate. A moving support member and a closing support member which is attached to the other side and which is locked to the other side of the frame body to support the closed door plate so as not to open the door plate, and the doors are provided on both sides of the frame body. A door plate receiving portion that rotatably supports the door plate by locking the rotation supporting member of the plate and that prevents the door plate in the closed state from being opened by locking the closing support member. It is characterized by having each.

[0008]

In the first aspect of the invention, since the door plate can be attached to the frame body in either a front opening or a rear opening, or a left opening or a right opening, it can be attached to an entrance or an entrance in a room of a building. When mounting, it becomes possible to adjust and mount in any of four modes of front opening or rear opening and left opening or right opening. Even if the door plate has front and back surfaces, adjust whether it is front opening or rear opening according to the front and back surfaces.

According to the second aspect of the present invention, the rotation supporting member for the door plate is attached to either one of the door plate receiving portions provided on both sides of the frame body. As a result, the door plate is rotatably supported by the frame body. The closing support member for the door plate engages with the other door plate receiving portion of the frame when the door plate is closed, and supports the door plate so as not to open.
