Description

The present invention relates to TobiraSo location. More specifically, in a door device that can provide sound insulation and air tightness as needed while having a ventilation path, it can ensure sufficient ventilation performance in a setting that allows ventilation and also privacy protection performance. about the high TobiraSo location.

  The door is originally intended to shield the inside of the room provided with the door, and many door devices that emphasize airtightness inside and outside the door have been constructed. However, with the revision of the building standards in 2003, it became necessary to take privacy protection measures including sound insulation measures due to the mandatory ventilation at the door installation part.

As a privacy protection measure, a sealing member that can be moved up and down is provided at the lower end of the door, and the sealing member is lowered as necessary to close the gap between the lower end of the door and the floor surface. There has been proposed a door device that provides airtightness and improved sound insulation performance (see Patent Document 1 as an example).
JP 2006-57364 A

However, the “24-hour ventilation sound insulation door” described in Patent Document 1 has the following problems.
That is, since the sealing member and related parts for operating the sealing member are necessary, the number of parts is large and the structure is complicated. For this reason, there has been a problem that it is easy to break down and is expensive.
In addition, ventilation inside and outside the door (ventilation) is performed using the gap between the bottom edge of the door and the floor in the width direction of the door, and because the structure uses the short side of the door, considering the vertical width of the gap, Since it is difficult to take a large opening area, it is difficult to obtain sufficient ventilation performance.

  Furthermore, since the gap that opens under the door in the setting that can be ventilated is transparent, the inside sign can be seen well from the outside. In other words, there is a structural problem that is undesirable from the viewpoint of privacy protection, because if you want to see it, you can look inside from the gap.

  Accordingly, an object of the present invention is to simplify the structure of a door device capable of providing sound insulation and airtightness as necessary while having a ventilation path, and ventilating performance in a setting that allows ventilation. The door device and the ventilation / sealing switching method in the door device are provided.

(Function)
The operation of the door device according to the present invention will be described. Note that, here, each constituent element of the present invention is given and described in correspondence with the reference numerals given to the respective parts in the embodiments described later, but this provision of reference numerals is only for easy understanding of the explanation. However, it does not mean that the constituent elements are limited to the above-described parts.

  When the door member (5) of the door device is rotated from the open state to the closing direction and stopped at the ventilation position by the ventilation position stop means (3), the door member (5), the frame member (1) and the door stop A ventilation space (venting path) (a1) is formed between the members (2). In this state, ventilation is possible on the inside and outside (for example, indoors and outdoors) across the door member (5), and mutual ventilation can be performed. Moreover, since the ventilation space (a1) is formed on the long side of the door member (5), the opening can be made larger than that formed on the short side as in the prior art. The ventilation performance can be secured sufficiently in the setting where ventilation is possible. In addition, since the conventional elevating sealing member is not used, the structure is simple.

  Further, in the state in which this ventilation can be performed, the door stop member (2) that can stop the rotation of the door member (5) becomes an obstacle, and the door member (5) from the outside side has a ventilation space (a1) The inside of the door member (5) cannot be seen through. Thereby, privacy protection performance is also high. Note that the gaps (S1, S2) between the upper and lower ends of the door member (5) (short side of the door member) and the floor and ceiling surfaces are when the door member (5) is stopped at the sealed position. Needless to say, it is formed so narrow that almost no ventilation is performed, or there are almost no gaps.

  When sealing the inner side and the outer side of the door member (5), as described above, at a position where the ventilation space (a1) is formed between the frame member (1) and the door contact member (2). Move the door member (5) from the state in which the door member (5) is stopped manually or by operating the switching operation means, and attach the back surface side of the door member (5) directly to the door contact member (2) or packing, etc. The door member (5) is stopped by the sealing position stop means (4) by being interposed and indirectly contacted. As a result, the ventilation space (a1) is closed and airtightness can be maintained between the door member (5) and the door stop member (2), and the inner side and the outer side of the door member (5) Sealed.

(A) In a state where a ventilation space is formed between the door member, the frame member, and the door stop member, ventilation can be performed on the inside and outside with the door member interposed therebetween, and mutual ventilation can be performed. In addition, since the ventilation space is formed on the long side of the door member, the opening can be enlarged compared to the conventional one formed on the short side, so that ventilation is possible. Sufficient ventilation performance can be secured. In addition, since the conventional elevating sealing member is not used, the structure is simple.

(B) In a state in which ventilation can be performed, the door stop member that can stop the rotation of the door member becomes an obstacle, and the inside of the door member cannot be seen from the outside of the door member through the ventilation space. Thereby, privacy protection performance is also high.

  The present invention will be described in detail based on the embodiments shown in the drawings.

(Function)
The operation of the door device A1 will be described with reference to FIGS.
The door member 5 of the door device A1 is rotated from the opened state to the closing direction, and the latch bolt 6 of the door member 5 is locked in the ventilation position stop hole 3 (see FIGS. 3 and 4). In this state, the front and rear surfaces of the door member 5 are parallel to the front end surface of the frame member 1, and between the front end of the door member 5, the frame member 1, and the contact member 2 as shown in FIG. 4. A ventilation space (venting path) a1 is formed.
Note that the front and rear surfaces of the door member 5 do not necessarily have to be parallel to the front end surface of the frame member 1. For example, in order to reduce the door angle at the airtight stop position, the ventilation stop position can be slightly inclined.
The same applies to the door member 5a described later.

  Thereby, ventilation can be performed indoors (upper side in FIG. 3) and outdoor (lower side in FIG. 3) with the door member 5 interposed therebetween, and mutual ventilation can be performed. In addition, since the ventilation space a1 is formed on the long side in the vertical direction of the door member 5, the opening (opening area) of the ventilation space a1 is compared with that formed on the short side in the horizontal direction. It is possible to ensure a sufficient ventilation performance in a setting that allows ventilation.

  Moreover, in the state which can perform this ventilation, the door stop member 2 which can stop rotation of the door member 5 becomes obstructive, and from the exterior side of the door member 5, the inside side of the door member 5 through the ventilation space a1. I can't see through. Thereby, privacy protection performance is also high.

The rotation of the member 5 is stopped. In this state, the latch bolt 6 can be locked by operating the thumb turn 61 as necessary.

  Thereby, ventilation space a1 is closed and airtightness can be maintained between the door member 5 and the packing 21 of the door contact member 2, and the inner side and the outer side of the door member 5 are sealed. Note that the gap S1 between the lower end portion of the door member 5 and the floor surface 102 and the gap S2 between the upper end portion of the door member 5 and the ceiling surface 103 are narrow so that almost no ventilation is performed as described above. Since it is formed, the sealing degree is not substantially affected.

FIG. 5 is a perspective explanatory view showing the first embodiment of the door device according to the present invention,
FIG. 6 is an explanatory view showing the structure of the frame member side of the door device shown in FIG.
7 is an explanatory view showing a ventilation stop position and a sealing stop position of the door member of the door device shown in FIG.
FIG. 8 is a partial enlarged view of P2 in FIG.
In the present embodiment, the same parts as those of the door device A1 are denoted by the same reference numerals in the drawing, and the description of the structure is basically omitted.

  The door device A2 is provided in the frame member 1, the door contact member 2 provided in the frame member 1, the ventilation position stop hole 3a and the sealed position stop hole 4a provided in the frame member 1, and the frame member 1. A door member 5a is provided.

A ventilation position stop hole 3a in which a latch bolt 6a of a door member 5a, which will be described later, can be locked is provided in the lower part of the intermediate portion in the depth direction of the locking tool 11a provided on one side of the frame member 1. .
Further, in the upper stage behind the ventilation position stop hole 3a (as shown in FIGS. 5 and 6, the ventilation position stop hole 3a and the sealing position stop hole 4a do not overlap in height) of the door member 5a. A sealing position stop hole 4a to which the lock bolt 7 can be locked is provided. The ventilation position stop hole 3a and the sealing position stop hole 4a are each a U-shaped hole with a cross-sectional shape.

In the ventilation position stop hole 3a, a roller 30 is provided with the axial direction vertically close to the back wall.
The roller 30 guides the curved surface portion 60 of the latch bolt 6a to assist the forward and backward movement of the latch bolt 6a (see FIG. 8A). The roller 30 is not necessarily provided.
Further, a roller 40 is provided near the front wall of the sealing position stop hole 4a so that the axial direction is vertical. The roller 40 assists the movement when the curved bolt portion 7 of the lock bolt 7 is guided to project the lock bolt 7 (see FIG. 8B).

  On one end face in the width direction of the door member 5a (the left end face in FIG. 7), a latch bolt 6a is provided at a height corresponding to the ventilation position stop hole 3a, and a height corresponding to the sealed position stop hole 4a. A lock bolt 7 is provided. The face plate 51, the latch bolt 6a, and the lock bolt 7 constitute a latch assembly (not shown) housed in the door member 5a.

  A thumb turn 71 and a handle 63 are provided on the inner surface side of the door member 5a. The handle 63 can be used to enter and exit the latch bolt 6a. The thumb turn 71 can be operated so that the latch bolt 6a can be accommodated from the protruding state (the state shown in FIG. 5). The latch bolt 6a can be locked in the ventilation position stop hole 3a, and the lock bolt 7 can be locked in the sealed position stop hole 4a. The thumb turn 71 and the lock bolt 7 constitute a switching operation means.

(Function)
The operation of the door device A2 will be described with reference to FIGS.
The door member 5a of the door device A2 is rotated from the opened state to the closing direction, and the latch bolt 6a of the door member 5a is locked to the ventilation position stop hole 3a (see FIGS. 7 and 8A). The lock bolt 7 is accommodated in advance so as not to protrude from the face plate 51 by operating the thumb turn 71 in advance. In this state, the front and rear surfaces of the door member 5a are parallel to the front end surface of the frame member 1, and as shown in FIG. 8A, the front end of the door member 5a and the frame member 1 and the door stop member 2 A ventilation space (venting path) a2 is formed between them.

  Thereby, ventilation can be performed indoors (upper side in FIG. 7) and outdoor (lower side in FIG. 7) across the door member 5a, and mutual ventilation can be performed. In addition, since the ventilation space a2 is formed on the long side in the vertical direction of the door member 5a, the opening (opening area) of the ventilation space a2 is compared with that formed on the short side in the horizontal direction. It is possible to ensure a sufficient ventilation performance in a setting that allows ventilation. Moreover, it is the same as that of the door device A1 in that privacy protection performance is high.

  When the inner side and the outer side of the door member 5a are sealed, the door is opened from the state in which the door member 5a is stopped at the position where the ventilation space a2 is formed between the frame member 1 and the door stop member 2 as described above. The thumb bolt 71 of the member 5 a is operated to cause the lock bolt 7 to protrude from the face plate 51. At this time, since the lock bolt 7 protrudes while pressing the curved surface portion 70 against the roller 40, the door member 5a moves to the door stop member 2 side by the reaction force. The rear surface side (inner side surface) of the door member 5a comes into contact with the packing 21 of the door contact member 2, and the lock bolt 7 is locked by the sealing position stop hole 4a. Further, the latch bolt 6a is guided by the roller 30 through the curved surface portion 60, and is accommodated therein to a required position by the reaction force.

  As a result, the ventilation space a2 is closed, and airtightness can be maintained between the door member 5a and the packing 21 of the door contact member 2, and the inner side and the outer side of the door member 5a are sealed. Note that the gap S1 between the lower end portion of the door member 5a and the floor surface 102 and the gap S2 between the upper end portion of the door member 5a and the ceiling surface 103 are narrowly formed so that almost no ventilation is performed. Therefore, it is the same as the door apparatus A1 that the sealing degree is not substantially affected.

  Note that the terms and expressions used in the present specification are merely explanatory and not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
