Abstract

(57) [Summary] [Purpose] The objective is to provide an inexpensive soundproof door that does not require manufacturing. [Structure] A pair of surface materials 4, 4 are attached to both sides of a frame 1 composed of vertical bars 2 and horizontal bars 3, and a plate-like heavy object 5 made of a high-density material is provided inside one of the surface materials 4, 4. The soundproof door A is characterized by being provided with.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a soundproof door that particularly considers sound insulation.

[0002]

[Prior Art]

 In general, doors for soundproof rooms, etc., where sound insulation is particularly required, are made of metal such as stainless steel instead of wooden doors. This is because the sound inside the room is transmitted to the outside of the door because the sound waves vibrate the door slightly, and this vibrates the air outside the room.Since the door is heavier, the vibration of the door itself is less likely to occur. Is.

The above-mentioned door tries to take soundproof measures by the material of the door itself, but on the other hand, there is a door that structurally takes soundproof measures.

For example, there is a soundproof door described in Japanese Patent Application Laid-Open No. 58-195682. This door has a sound absorbing material that is stuck between a pair of surface materials without any gaps. The sound absorbing material tries to absorb the sound transmitted to the door.

[0005]

[Problems to be solved by the device]

 However, in the conventional metal doors described above, the material cost per area is high, and the door price is high.

Further, in the soundproof door described in the above publication, since the sound absorbing material is stuck between the surface materials without any gap, the soundproofing effect is unclear depending on the accuracy of the sticking of the sound absorbing material. Also, the work of sticking the sound absorbing material between the surface materials without any space is troublesome.

The present invention has been made in view of the above problems, and an object thereof is to provide an inexpensive soundproof door that does not require time and effort for manufacturing.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, in the soundproof door of the present invention, a heavy object made of a high-density material is provided between a pair of surface materials provided with a predetermined space. To do.

[0009]

[Action]

 In the present invention, even if the sound wave generated in the room is transmitted to the door, the weight of the door is made heavy by the heavy object placed between the surface materials, so that the vibration of the door due to the sound wave is suppressed, This can improve the soundproofing of the door.

Further, since the mounting accuracy of the heavy object does not greatly affect the soundproof effect, the manufacturing is less laborious than the door having the conventional sound absorbing material.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

First, the configuration of the embodiment will be described.

FIG. 1 is a perspective view showing a soundproof door A according to an embodiment of the present invention, and FIG. 2 is a vertical section showing a soundproof door A according to the embodiment of the present invention. In FIG. The reference numeral 1 includes a vertical rail 2 and a horizontal rail 3.

A pair of surface materials 4 are attached to the frame 1. The surface material 4 is made of a relatively thin material such as wood, and a light weight material such as a vinyl chloride sheet is used for the quality board.

A plurality of thick and heavy plate-like heavy objects 5 are fixed to the inner surface of the one surface member 4 by, for example, adhesion with an adhesive or nailing. As a material of the plate-like heavy object 5, an inexpensive material having a large specific gravity such as gypsum board or MDF can be adopted.

In the soundproof door A according to the embodiment of the present invention, even if a sound wave generated in a room is transmitted to the door A, the weight of the door A becomes heavy due to the plate-like heavy object 5 in the door A. Since the vibration of the door A due to the transmission of the sound wave is suppressed, the soundproofness of the door A can be improved.

As described above, in the soundproof door A of the embodiment, the weight of the door A is increased by attaching the plate-like weight 5 having a large specific gravity, which is inexpensive and easy to attach, to the surface material 4 in the frame 1. Therefore, the sound insulation can be improved. Further, the plate-like heavy object 5 is for increasing the weight of the door A, and does not require particularly strict mounting accuracy, so that it does not require manufacturing labor and can be finished at low cost.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Also included in the present invention.

For example, in the embodiment, the plate-like heavy object is attached to one surface material, but it may be attached to both surface materials to further improve the soundproofing of the door. Further, the plate-like heavy object having the shape shown in the embodiment is not limited to the plate-like heavy object having a larger shape, and the plate-like heavy object having a smaller shape may be dispersed and attached in large numbers.

[0020]

[Effect of the device]

 As described above, in the soundproof door of the present invention, since the weight of the door is increased by mounting the heavy object inside the door, it is possible to improve the sound insulation property and reduce the manufacturing labor. Therefore, it is possible to provide an inexpensive soundproof door.
