The door unit 11 has a frame-shaped door frame device 14 and a door frame device. It has a door 15 that is openably and closably disposed inside 14.

The door 15 has a plurality of hinges 2 on one side.
The door frame device 14 is openably and closably supported by the door frame device 14 via the first and second doors 21, and is opened by being pivoted to one space side such as a room, which is partitioned by the partition wall 12.

On the other side of the door 15, a door frame device 14 is provided.
In contrast, a door knob 22 for opening and closing the door 15 is provided.

The door frame device 14 has a door frame 31 installed in a gate shape along the left and right edges and the upper edge of the opening 13 of the partition wall 12, and extends along the inside of the door frame 31. A door stop 32 that regulates the closing position of the door 15 is provided.

FIGS. 1 and 2 show part of the left and right portions of the door frame 31. FIG. The door frame 31 is a long, substantially flat frame plate 3 arranged along the inside of the opening 13 of the partition wall 12.
5, and substantially L-shaped frame portions 36 attached to both side surfaces of the partition wall 12 project from both side surfaces of the frame plate 35. At the approximate center of the inner surface of the frame plate 35, a concave portion 37 in which the door stop 32 is arranged is formed along the longitudinal direction of the frame plate 35.

The door stop 32 is long and has a width of the frame plate 35.
The width of the concave portion 37 of the frame plate 35 is smaller than the width of the concave portion 37 of the frame plate 35.
Along the edge of the frame plate 35 so as to protrude from the inner surface of the frame plate 35, and is configured to restrict the closed position of the door 15 on one side surface 40.

On the outer side of the door stop 32 facing the frame plate 35, a plurality of mounting portions 41, which are bonded and fixed by an adhesive, for example, are formed at predetermined intervals in the concave portion 37 of the frame plate 35, A rectangular groove 43 is formed between the plurality of mounting portions 41, and each of the grooves 43 has
A plurality of ventilation holes 44 are formed to penetrate through one side surface 40 and the other side surface 42 of the second.

The door stop 32 is disposed substantially at the center of the recess 37, and gaps 45, 46 are formed between the side faces 40, 42 of the door stop 32 and the recess 37, and the gaps 45, 46 and the vent 44 are provided. It is configured to allow air to flow between and. The ventilation port 44 is formed in a slit shape with the frame plate 35, and is arranged in an area inside the recess 37.

The door frame 31 and the door stop 32 are made of, for example, a material such as wood, plastic, or a composite thereof, and the upper portion of the door frame 31 is configured similarly to the left and right portions. I have.

In such a configuration, the door 15 is opened and closed as shown by the arrow in FIG. When the door 15 is closed, the door 15 approaches or touches one side surface 40 of the door stop 32, and the gap between the one side surface 40 of the door stop 32 and the door 15 is small, and sufficient ventilation is provided. However, a gap 51 is formed between the peripheral surface of the door 15 and the inner surface of the frame plate 35 to allow the door 15 to rotate and open. The gap 51, the gap 45, and the vent 44 A passage through which air flows, that is, the bent air passage 52 is formed with the gap 46. (See Fig. 1)

Therefore, the door 15 through the ventilation path 52
The air flow from one side to the other side passes through a gap 51 between the door 15 and the frame plate 35 as shown by an arrow in FIG.
It bends at 5 and flows through the vent 44 and again at the gap 46.

The flow of air from the other side of the door 15 to one side is reversed. Thus, even in the state where the door 15 is closed, it is possible to obtain sufficient air permeability between the inside and outside of the room, that is, between the room and the corridor, through the ventilation path 52.

Since the air passage 52 is bent as described above, direct leakage of light through the air passage 52 can be reduced, and sound is attenuated when passing through the bent air passage 52. In addition, it is possible to reduce leakage of sound, obtain sufficient air permeability, and prevent leakage of light and sound to secure a private space.

Further, since the door stop 32 itself has an opening 44 formed therein to allow air to flow at the closed position of the door 15,
Compared to a conventional case where a plurality of partial packings are exposed in a protruding state, air permeability can be ensured when the door 15 is closed without impairing the appearance and when the door 15 is closed. In particular, by arranging the vents 44 of the door stop 32 in the recesses 37 of the frame plate 35, the vents 44 can be hardly seen from the outside.

The groove 43 forming the vent 44 of the door stop 32 is not limited to a square shape, but may be formed in an arc shape as shown in FIG.
Even when the vent 44 can be seen through the holes 5 and 46, the design appearance can be improved, and the vent 44 can be blocked by arranging and closing a filter having air permeability, thereby preventing the passage of pests and the like.

In the above-described embodiment, the door frame 31 is provided on the partition wall 12, and the door stop 32 is disposed on the door frame 31. As long as the configuration does not leak, the door frame device is not limited to the present embodiment.
