DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for both ventilation and sound insulation of a door.

[0002]

2. Description of the Related Art In a door portion, a structure is provided which allows ventilation while preventing propagation of noise and the like.
The one shown in FIGS. 4 and 5 is known. In any of the structures, the lashes 81 and 82 are attached to both sides of the door 80 at different heights.
1 and 82 are communicated with each other by a ventilation path 83 provided inside the door 80, and a sound absorbing member 84 is provided in the ventilation path 83.
Has been decorated.

The lower end of the door 80 is at the time of closing the door 80, and has a door stop 8 of a threshold 86 provided on the floor 85.
7. Although not shown, the upper end and the side end of the door 80 come into contact with a door stop provided on the door frame. Therefore, ventilation is ensured by the ventilation path 83, and noise and the like are:
The sound absorbing member 84 in the ventilation path 83 and the contact with the door 80 by the door stop 87 or the like are cut off or lowered.

In the structure shown in FIG. 4, the sound absorbing member 84 is merely arranged so as to face a vertical portion in the air passage 83. On the other hand, in the structure shown in FIG. Are provided so as to face the vertical portion in the ventilation path 83, and are extended in the up-down direction to positions directly facing the galleries 81 and 82. Therefore, from the standpoint of soundproofing performance, it can be said that the structure shown in FIG. 5 is more suitable because the probability of noise and the like colliding and contacting the sound absorbing member 84 is higher.

[0005]

The structures shown in FIG. 4 and FIG.
In need. Therefore, there is a disadvantage that the appearance as the door 80 is poor. In addition, since it is necessary to provide a sill 86 having a door stop 87 on the floor surface 85, this leads to the generation of a step on the floor surface 85, and this step is particularly difficult for the elderly and the physically handicapped. It has become an obstacle in traffic.

[0006] The present invention has been made in view of the above circumstances, and can improve the appearance as a door,
It is another object of the present invention to provide a structure for both ventilation and sound insulation of a door portion, which can prevent a step from obstructing a floor surface or the like from passing.

[0007]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the combined ventilation / sound insulation structure of the door portion according to the present invention, the upper or lower end face of the closed door and the building frame side facing this end face (the upper face of the door is opposed to the door frame. A partition member that blocks this gap is provided between the door and the door, and the door faces the lower end of the door. A pair of openings are provided on both sides of the partition member in the above, and the two openings are communicated with each other by a ventilation path passing through the inside of the door, and a sound absorbing member is provided in the ventilation path.

Therefore, ventilation between one side and the other side of the door is ensured by a path extending from one opening through the ventilation path to the other opening (or a path opposite thereto). You. On the other hand, noise and the like are cut off or reduced by the sound absorbing member and the partition member in the ventilation path. Here, since the above-mentioned openings are all provided at the upper or lower end surface of the door, they do not appear in a normal state, and there is no risk of deteriorating the appearance of the door.

The partition member has an operator which is pressed and released when the door is opened and closed. When the operator is pressed, the door is pressed from the end face side of the door to the building frame side (floor surface or the like) opposed thereto. If the blade descends until it touches, and the blade returns to the original position when the pressure is released, the blade blocks the gap only when the door is closed, so that the door stops on the building frame side There is no need to provide them.

In other words, the use of such a partition member does not cause a level difference on the floor surface that hinders the passage, so that the passage is particularly easy for the elderly and the physically handicapped. is there. Further, even when the partition member is provided at the upper end of the door, there is an advantage that the structure can be simplified in that the door frame does not require a door stop. When a partition member having such a structure is used, sound insulation can be improved by providing a blade receiver on the building skeleton side for improving adhesion to the blade, and at the same time, drafts (air flow with a momentum) can be provided. ) Can be prevented from invading and dust can be prevented from being rolled up and adhered to and grown, and a rapid temperature change can be prevented.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 and FIG. 2 show a first embodiment of a door portion to which a combined ventilation and sound insulation structure according to the present invention is applied. In the first embodiment, the door 2 is attached to a door frame 3 by a hinge 4 so as to be freely opened and closed. Between the lower end surface 5 of the door 2 and the floor 6, a gap 7 having a constant height is formed in the width direction of the door 2.

The lower end of the door 2 is located at the center of the lower end surface 5 in the thickness direction only when the door 2 is closed.
A partition member 10 that blocks the gap 7 is provided. In the thickness direction of the lower end surface 5, a pair of openings 1 is provided on both sides of the partition member 10.
The two openings 11 and 12 are communicated with each other by a ventilation path 13 passing through the inside of the door 2. A sound absorbing member 14 is provided inside the ventilation path 13.

The partition member 10 has an actuator 18 projecting from a side end face 17 of the door 2 to which the hinge 4 is attached. When the door 2 is closed, the actuator 18 is pressed by contact with the door frame 3, and the door 2 is closed.
When the door 2 is opened, the pressing is released, and the pressing and releasing are repeated as the door 2 is opened and closed.

When the actuator 18 is pressed, the blade 19 can be lowered over the entire width of the door 2 from the lower end surface 5 side of the door 2 to contact with the floor surface 6. When the pressing of the actuator 18 is released from this state, the blade 19 can be raised and returned to the original position.
No. 82155, it is described as a “door gap closing device”, in which the actuator 18 is described as a “slide bar” and the blade 19 is described as a “vertical sliding member”.

On the other hand, on the floor 6, a blade receiver 20 for improving the adhesion to the blade 19 is provided at the other end of the partition member 10 where the blade 19 contacts when the door 2 is closed. . In the first embodiment,
The blade receiver 20 has a groove shape in cross section. Therefore, a fitting groove 22 for accommodating the blade receiver 20 in a lowered state is formed on the floor surface 6.

The blade receiver 20 can be obtained by drawing or extruding a metal such as an aluminum alloy or stainless steel, plastic, or the like, or by grooving hard wood. Note that the side wall 23 is positioned so that the door 2 is opened from the closed position.
Are slopes to escape interference with the vertical movement of the blade 15.

The blade receiver 20 is fixed in the fitting groove 22 by a wood screw, an adhesive or the like (not shown). on the other hand,
A pair of openings 11 and 12 provided at the lower end of the door 2
Are formed as a large number of holes or slits provided along the width direction of the door 2 with respect to the lower rail 25 provided to hold the partition member 10 from both sides in the thickness direction of the door 2. Providing a large number of small holes is more advantageous in preventing pests and the like from entering the ventilation path 13.

Therefore, these openings 11 and 12
A space formed inside the door 2 (between the front and back exterior plates 26) is communicated with the outside. This communication state is restricted to a predetermined height range by the inner bar 27 in the door 2 and the sound absorbing member 14 provided below the inner bar 27, so that the ventilation path 13 is formed. The sound absorbing member 14 is made of a porous sound absorbing material such as glass wool.
The sound absorbing member 14 is packed so as to fill a predetermined height area inside the door 2 (a predetermined layer thickness dimension below the inner bar 27), and is prevented from falling off by the perforated plate 28. .

Note that, as shown in FIG.
It is not necessarily limited that the upper side of the above is backed up by the internal rail 27. Also, the perforated plate 28 is not indispensable. In such a door section, when the door 2 is closed, the blade 19 of the partition member 10 descends and comes into contact with the blade receiver 20, so that the gap 7 is closed. Therefore, propagation of air flow, noise, and the like through the gap 7 is prevented. Light leakage and the like are also shut off.

However, the air passage 13 extends from one of the openings 11.
Is allowed to flow to the other opening 12 through the opening (of course, the flow in the opposite direction is also allowed), whereby the ventilation through the door 2 is ensured. At this time, the air flow passing through the ventilation path 13 always collides with or contacts the sound absorbing member 14, so that the propagation of noise or the like on the air flow is prevented.

Since the openings 11 and 12 are arranged so as not to be seen after ensuring ventilation and preventing or reducing noises and the like, the appearance of the door 2 is not deteriorated. It is not expected. FIG. 3 shows a second embodiment of a door unit to which a combined structure of ventilation and sound insulation according to the present invention is applied.

The second embodiment is different from the first embodiment in that the partition member 10 projects upward from the lower rail 25 of the door 2 and an upward projection 30 on the floor 6. It has a lower protrusion 31 and is formed by abutting these when the door 2 is closed. The upper ridge 30 and the lower ridge 31 can be formed integrally with the lower bar 25 and the floor material, as shown in the figure, or can be provided as a separate member. .

The rest of the configuration and the operation and effect are substantially the same as those of the first embodiment. By the way, the present invention is not limited to the above embodiments. For example, the ventilation / sound insulation structure according to the present invention can be applied to the upper end of the door 2. The sound absorbing member 14 is not limited to using a porous sound absorbing material, and may be formed as an additional structure that expands and contracts the passage area of the air passage 13 in the traveling direction.

The blade receiver 2 used in the first embodiment
0 may be provided in a flat state with the floor surface 6 or may be omitted in some cases.

[0025]

As is apparent from the above description, in the door ventilation / sound insulation structure according to the present invention, the ventilation between one side and the other side of the door is limited to the upper end surface of the door or the other side. It is secured by a path extending from one opening provided on the lower end surface to the other opening through the ventilation path, whereas noise and the like are generated by the sound absorbing member provided in the ventilation path and the door. It is blocked or lowered by a partition member for blocking a gap generated on the upper end side or the lower end side.

Since the above-mentioned ventilation openings are provided on the upper end surface or the lower end surface of the door, they are not normally visible and therefore do not deteriorate the appearance of the door. When a partition member having a blade that moves up and down with opening and closing of the door is adopted,
Since there is no need to provide a door stop on the building skeleton side, not only the structure can be simplified, but also there is no step on the floor surface, and there is no inconvenience in traffic.

In this case, providing a blade receiver on the floor or the like has the advantage that sound insulation and the like can be enhanced, and that dust and the like due to intrusion of draft can be prevented from being rolled up and adhered to, and a rapid temperature change can be prevented.
