Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building door.

[0002]

[Prior Art]

 As doors for buildings, doors with a panel-shaped body fitted in the door frame have been widely used. By pivotally attaching one side edge to the opening of the building, these doors can be freely opened and closed with respect to the opening.

[0003]

[Problems to be solved by the device]

 Although the above-mentioned conventional door is preferable for maintaining airtightness, ventilation cannot be performed when it is closed. Therefore, if the door is opened for ventilation, the door may be swung by the wind and may be closed due to shock, and the opened door may be an obstacle. Furthermore, when a person passes through a door, the door must be opened and closed, but in order to open and close the door, a space within the opening and closing range of the door must be opened, so Effective area is reduced. Incidentally, in the case of sliding doors, the above problems do not occur, but sliding doors need to be provided with door pockets, grooves, rails, etc. in the building. Although the accordion door does not have the above-mentioned problems, it does not have a frame, and thus has problems in terms of airtightness, keeping independence of rooms, and the like. The present invention has been made to solve the above problems in doors.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a door in which one side edge is pivotally attached to an opening in a building, in which an openable / closable portion that can be opened and closed while the door is closed is provided in a door frame. The present invention provides a door characterized by being provided.

[0005]

[Action]

 In the door according to the present invention, the openable / closable portion in the door frame is opened / closed as necessary with the door closed, that is, with the door closed to the opening of the building. For example, when it is necessary to ventilate the room, the openable part in the door frame is opened with the door closed. Also, for example, when a person needs to pass through the door, the openable / closable portion in the door frame is opened with the door closed. In either case, since the door itself is closed and only the open / close part in the door frame is opened / closed, it is not necessary to leave a space for opening / closing the door itself, and the open door is an obstacle. It never becomes.
