Abstract

<P>PROBLEM TO BE SOLVED: To impart a ventilating function and a soundproofing function to a door for partitioning the interior of a building, while ensuring barrier-free properties. <P>SOLUTION: The door 100 is formed of an inner plate 11 on a toilet 201 side, an outer plate 12 on a corridor 202 side, a sound-absorbing material 15 attached to the inside of each of the inner and outer plates 11, 12, an intake port 13 and an air supply port 14 arranged in the inner and outer plates 11, 12, respectively, across a space C and a length L therebetween, a cam-lifting hinge for attaching a door main body 1 to a frame 203, a lower seal 3, etc. The door 100 may includes a blower in the space C. Thus, the interior of the toilet takes in ventilating air through the intake port and the air supply port which communicate with each other via the space C. When the door is closed by the cam-lifting hinge, the lower seal 3 makes contact with a floor surface 200, and therefore flushing sound in the toilet does not leak from the floor surface to the outside. Although the ports 13, 14 communicate with each other, sound emitted to the outside is drastically reduced by virtue of the reflection and sound-absorbing effect of the sound-absorbing material. Further, in spite of sealing by the lower seal 3, the floor surface has nothing thereon, and therefore, the barrier- free function of the door is ensured. <P>COPYRIGHT: (C)2004,JPO

2. Description of the Related Art For example, in a toilet of a house or public facility,
The inside of the door, the inside of the toilet, and the outside of the corridor, etc., have the same floor level, but a partition that is slightly higher than the floor is installed between them, and an appropriate partition is provided between this and this partition. It is often the case that a door is attached so as to form a gap, and this gap is used as an air intake portion for ventilation in the toilet. Further, a louver for ventilation may be provided together with such a gap at the lower end of the door. And, the door itself is also a laminated structure of plate materials, which is usually not soundproof.

However, with such a structure, there is a problem that the flushing sound of flushing inside the toilet is heard as a very loud sound outside the toilet. Further, in recent years, there has been a problem that a barrier-free structure, which is required as a dwelling structure of a dwelling or facility that is easy for the elderly and physically handicapped people to live, cannot be achieved.

[0004]

[0009]

1 to 3 show an example of the structure of a soundproof door to which the present invention is applied. The door 100, which is a soundproof door, for example, a toilet door, is a door frame 203 as an opening between a toilet 201 that is one side compartment and a passage 202 that is the other side compartment in which a floor surface 200 is formed barrier-free in a building. It is a soundproof door that can open and close a frontage 204 formed by the floor surface 200 and the door body 1, and has a door body 1, hinges 2 (FIGS. 2 and 3) that are support members, a lower seal 3 that is a seal member, and the like. .

The door body 1 has an inner surface plate 11 which is a flat one side member facing the toilet 201, an outer surface plate 12 which is a flat other side member, and one side opening provided in a part of the inner surface plate 11. One intake port 13, the other side opening 1
4, sound absorbing material 15, and the like.

The outer face plate 12 faces the passage 202 and the inner face plate 1
The upper and lower frame plates 16 and 17 are spaced apart by a distance d so as to face 1
Is connected to the inner surface plate 11. The air supply port 14 is
In the present example, it is provided at a position separated by a distance L downward from a position facing the intake port 13 in a part of the outer surface plate 12. The distance d is determined depending on the required soundproofing performance, etc., but is usually set to a size of about 40 mm to 80 mm. Distance L
Is, for example, about 1.5 m.

At least any one of the surfaces of the inner surface plate 11 or the outer surface plate 12 on the space C side of the sound absorbing material 15 is left with a space C in which air communicates between the intake port 13 and the air supply port 14 in the central portion. In this example, it is provided on both sides as that side. The sound absorbing material 15 is usually formed in a state in which the inner and outer surfaces of glass wool are covered with a protective sheet 15a and a soundproof sheet 15b. The space C may have a narrow width as long as a small amount of air is conducted therethrough. Therefore, it is appropriately determined depending on the thickness of the door body 1 and the thickness of the sound absorbing material 15 for obtaining a necessary soundproof effect. It is also possible to increase the thickness of the sound absorbing material 15 and attach it to only one of the inner surface plate 11 and the outer surface plate 12.

The hinge 2 has a structure for supporting the door body 1 so that it can be opened and closed so that it rises when the door body 1 opens and descends when it closes. In this example, the hinge 2 is a cam lift hinge shown in FIG. Blades 21 and 22 for attaching and connecting the door body 1 and the door frame 203, upper and lower cylindrical bodies 23 and 24 integrally formed with the respective blades, a cam follower 25 and a cam surface formed on each of these. 26, a shaft portion 27, a boss portion 28, and the like. The cam surfaces 26 are two surfaces 2 each having a lift h at every 180 °.
6a and 26b, and correspondingly, cam followers 25 are also provided in two rows 25a and 25b.

The lower seal 3 is provided on the lower end surface of the door body 1, and is formed so as to contact the floor surface 201 when the door body 1 is closed. That is, since the hinge 2 is a cam lift hinge, when the door main body 1 is opened, as shown by the two-dot chain line in the lower right of FIG. When the door body is closed, the lift h becomes 0, so that the door 201 comes into contact with the floor surface 201 as shown by the solid line in FIG. The lower seal 3 may be pressed against the floor surface 201 to some extent when the door is closed. The lower seal 3 is made of, for example, a material such as sponge rubber that is flexible but has a certain density and a small friction coefficient, and has a cross section of a tip portion formed in a square shape or an arc shape.

When the door is closed, the door body 1 is sealed with the floor surface 201 by the lower seal 3 as described above, and the packing 205 attached to the door frame 203 allows the door body 1 to be sealed with the door frame. Both sides and top are sealed.

The door 100 as described above is used as a toilet door in a barrier-free building and exhibits the following functions. In the toilet 201 designed to take in ventilation air from the passage 202 side of the building, a ventilation fan (not shown) is usually provided so as to discharge the internal air, and this is operated when the toilet is used. The ventilation air at this time does not come from between the lower end of the door 100 and the floor surface 200 as in the conventional case, but from the air supply port 14 on the aisle side to the intake air on the toilet side via the space C of the sound absorbing material 15. It is taken into the toilet 201 through the mouth 13.

In the toilet, the user flushes flush water after use. At this time, the flushing sound is generated in a considerable amount. On the other hand, in the prior art, since the ventilation space was provided at the lower end of the door as described above, the sound radiated directly to the outside passage side through this portion. Since it is closed at 3, it is possible to sufficiently prevent the flashing sound from diverging to the outside. In this case, since the door 100 is attached by the cam lift type hinge 2, even when the lower seal attached to the lower end of the door 100 is sufficiently pressed against the floor surface 200 to be in close contact with the floor seal, the lower seal 3 is removed from the floor surface when the door is opened. Since they gradually move away from each other, it does not affect the opening and closing of the door, and the airtightness can be maintained and the transmission of sound to the outside can be effectively prevented.

On the other hand, the gap at the bottom of the door is sound-insulating, but since the intake port 13 and the air supply port 14 are electrically connected for ventilation, the flash sound is transmitted during this period. Since the respective mouths are provided at a distance L and the sound absorbing material 15 is disposed on both sides of the space C through which the air passes, the flash sound is attenuated by refraction, reflection and interference between sound waves. It is absorbed by the sound absorbing material and loses sonic energy. As a result, the flushing sound transmitted to the outside can be significantly reduced.

The door 10 is used when entering or leaving the toilet.
When 0 is opened, the door 100 is opened together with the lower seal 3. Therefore, although the seal is formed at the time of closing, there is nothing on the flat floor surface 200 and the state is maintained as it is. It is possible to reliably maintain the barrier-free function between compartments.

As described above, according to the door to which the present invention is applied, it is possible to maintain the barrier-free function and satisfy the ventilation condition, while significantly reducing the external noise. The inventors conducted noise experiments using a conventional door and a door to which the present invention was applied, and obtained the following results: Used door; Dimensions (height x width x thickness) ---- 1800mm × 900mm × 50mm Sound absorbing material thickness ---- 15mm Intake and air inlet dimensions ---- Height 100mm × Width 200mm Distance between ports L ---- 1500mm Bottom seal thickness ---- 10mm (Door Seal compression amount when opening and closing 2mm) Conventional lower door ventilation gap ---- 10mm Measurement result of flushing sound of toilet; inside of toilet ---- 79dB Outside of toilet 1m away from conventional door- --- 74 dB Door of the present invention --- 65 to 70 dB FIG. 4 shows another example of the door to which the present invention is applied.

In the door 100 of this example, the blower 4 is provided in the space C. Since the blower 4 is provided in the narrow space C, it depends on its size, such as from a household toilet to a public facility toilet, but for example, it has an air volume of 0.2 to ² m ³ / min and an electric power of 30 to 300 W. It has a small capacity.

By providing the blower 4 as described above, even if a person is not in the toilet and is not operating the ventilation fan in the toilet, the blower 4 is kept in operation so that the passage 2
Ventilation can be constantly performed so that outside air is taken in from the 02 side and exhausted from the ventilation port of the ventilation fan. As a result, it is possible to prevent leakage of odors to the outside and stagnation of bad odors in the toilet with little power consumption. In this case, even in a toilet with a window, the window is often closed so that the inside cannot be seen from the outside, and thus such a blower 4 is effective.

FIG. 5 shows still another example of the door to which the present invention is applied. The door 100 of the present example has a door frame 5 as a frame member formed so that the door body 1 and the hinge 2 are attached and are fitted into the opening 204 formed in the frame 203 of the building. According to the door device having this structure, the attachment and adjustment of the cam lift type hinge 2 and the contact state of the lower seal 3 with the floor surface 200 can be adjusted in advance in the factory. As a result, the work of attaching the door to the building can be greatly facilitated.

In the above, the case where the soundproof door of the present invention is used as a door for a toilet has been described. However, the present invention is applicable to a barrier-free building such as a conference room, a play room, a smoking room or a karaoke room. It can be applied between other suitable compartments for the purpose of ventilation through parts and noise protection.

[0025]

As described above, according to the present invention, in the first aspect of the present invention, the soundproof door is provided with the flat one side member facing the one side compartment and the other flat side surface facing the other side compartment. The members are connected to each other with a space so as to face each other, and one side opening and the other side opening are provided at positions spaced apart from the positions facing a part of each member, and the air is flown from the one side opening to the other side opening. Since a sound absorbing material is provided on the space side surface of at least one of the one side member and the other side member, leaving a space for conduction, it is necessary to ensure the ventilation between both compartments while exhibiting the soundproof effect. You can

That is, since the sound absorbing material is provided on at least the space-side surface of the one side member or the other side member, that is, the inner surface thereof, the sound wave attempting to pass between the two compartments can be absorbed thereby to generate the soundproof effect. it can. In addition, since the openings on the one side and the opening on the other side are conducted through the passage, the air can be conducted between the two compartments, and the ventilation is secured. In this case, since the openings on the one side and the opening on the other side are provided at positions separated from the positions facing each other by a distance, the air waves through which the sound waves directly pass or conduct. There is no direct transmission of sound waves through, and the sound waves are greatly attenuated by diffraction, reflection, absorption, etc. during passage through the passage.

The door is supported by an elevating and lowering support member so as to be opened and closed so as to be raised when it is opened and lowered when it is closed, and is in contact with the lower end surface of the door body and the floor surface when it is closed. Since the seal member is attached, even if the floor surface of the one side section and the other side section is flat and barrier-free, while maintaining its function, the conduction between the two sections is substantially cut off, A soundproof effect can be obtained. In this case, since the seal member separates from the floor surface when opening the door, it is possible to ensure a smooth opening / closing operation of the door.

Therefore, according to the door of the invention of claim 1, it is possible to obtain the ventilation effect and the soundproofing effect while maintaining the barrier-free function. That is, the three functions required for the door can be satisfied at the same time.

According to the second aspect of the present invention, since the blower is provided in the space through which the air communicates, it is possible to forcibly ventilate between the two compartments. As a result, even when the positions of the openings on the one side and the other side are sufficiently displaced and the passage is narrowed to enhance the soundproof effect, it is possible to reliably obtain the desired ventilation amount.

In the third aspect of the invention, since the door is used between the one side compartment and the other side compartment when the toilet is a toilet, the structure becomes more effective. That is, although a ventilation fan is usually used in the toilet, since air for that is obtained by the opening on one side and the opening on the other side that are in communication with each other, it is possible to quickly and reliably ventilate the inside of the toilet, and the usage conditions of the toilet are Can be maintained well. In addition, a considerable flushing sound is generated when flushing water is flushed in the toilet, but its diffusion to the outside is prevented. The toilet is a facility that is used by elderly people and people with physical disabilities, but since the barrier-free function is secured at this time, it is easy for such people to use.

If a blower is provided in the ventilation space,
It is possible to prevent the odor in the toilet from leaking to the outside by constantly using this and blowing the air from the other compartment to the toilet which is the one compartment. As a result, in a building with a barrier-free structure, it is possible to completely prevent the leakage of foul odors while satisfying the soundproof performance. In this case, since the blower is provided in the passage, the blower is inherently small in size, and the power consumption is sufficiently small even during continuous operation, and noise can be eliminated. Then, even if the amount is small, it is possible to prevent leakage of odor by sending out air.

According to the fourth aspect of the present invention, since the door body and the supporting member are provided with the frame member formed so as to be fitted into the opening, these can be integrally manufactured in the door production factory. . As a result, it is possible to easily and appropriately adjust the lifting support type support member that requires a certain degree of skill in the factory, and ensure the smooth opening and closing of the door as well as the sealing property of the lower part of the door on the barrier-free floor surface. Further, the installation work of the door in the building can be greatly facilitated, and the productivity of the door portion of the building can be improved as a whole.
