Abstract

(57) [Summary] [Purpose] To provide a door with high sound insulation performance. [Structure] A door 1 having upper and lower, left and right frames 2 and an end plate 9 fitted in a space surrounded by the ends 2 and having a thin peripheral edge portion. The mirror plate 9 includes a front plate 10, a back plate 11, and a sound insulation sheet 12 interposed between the front plate 10 and the back plate 11.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device relates to a door.

[0002]

[Prior art]

 Conventionally, the following doors are known. That is, it is known that the frame has upper, lower, left and right frames, and a mirror plate fitted in a space surrounded by these frames, and the peripheral edge portion of the mirror plate is thin.

[0003]

[Disadvantages of the prior art]

 The conventional door has the following drawbacks. That is, in order to make the door look three-dimensional and luxurious, the thickness of the peripheral edge of the end plate is thin, but the sound insulation performance of the end plate (and by extension, the door) is reduced by that much. There was a drawback.

[0004]

[Means for eliminating the above drawbacks]

 This invention adopts the following means in order to solve the above-mentioned drawbacks. In this invention, the mirror plate has a front plate, a back plate, and a sound insulating sheet interposed between the front plate and the back plate.

[0005]

[Function of the device]

 This device has the following actions. The sound insulation sheet inserted between the front plate and the back plate can improve the sound insulation performance of the door compared to the conventional one.

[0006]

【Example】

 The present invention will be described below based on an embodiment shown in the drawings. In this specification, the front means the front side of the paper of FIG. 1, the back means the back side of FIG. 1, the left means the left side of FIG. 1, and the right means the right side.

The door 1 has upper and lower, left and right stiles 2, a sill 2 that is stopped at the middle of the height of the left and right stiles 2, and an end plate 9 that is fitted in a space surrounded by these stiles 2. is doing.

As shown in FIG. 2, the frame 2 includes a core material 3 made of laminated wood, a molding part 4 made of a solid material attached to an inner surface of the core material 3, front and back surfaces of the frame 2, and It has a decorative plate 5 which is attached to a part of the front and back surfaces of the molding part 4 and is made of a veneer, MDF or the like. A groove 6 into which the peripheral edge of the end plate 9 is fitted is formed on the inner side surface of the molding portion 4.

As shown in FIG. 2, the end plate 9 includes a front plate 10, a back plate 11, and two sound insulating sheets 12 interposed between the front plate 10 and the back plate 11. ing. The front plate 10 and the back plate 11 include a core material 14 made of a particle board, and a molding portion 15 made of a solid material attached to an inner surface of the core material 14 and having a thin wall toward the outer peripheral portion. And a decorative plate 16 composed of a veneer, MDF, etc., which is attached to a part of the front surface of the front plate 10 and the front surface of the molding portion 15 and a back surface of the back plate 11 and a part of the back surface of the molding portion 15. Have As the sound insulating sheet 12, for example, a soft plastic sheet (thickness: 1.2 mm, surface density: 2.1 kg / m ² ) to which a special high density filler is added is suitable.

In order to prevent sound from leaking from the connecting portion between the molding portion 4 and the molding portion 15, the molding portion 15 is forcibly fitted into the groove 6, and the molding portion 4 and the molding portion 15 are connected together. An adhesive (not shown) is interposed between the first and second electrodes 15.

[0011]

[Effect of device]

 The present invention has the following effects due to the above-described configuration. The sound insulation sheet inserted between the front plate and the back plate can improve the sound insulation performance of the door compared to the conventional one.
