[Industrial applications]

 The present invention mainly relates to a flush door attached to an entrance.

[0002]

[Prior Art]

 As a conventional flush door, for example, one disclosed by Japanese Utility Model Laid-Open No. 2-51683 is known. The door according to this publication is one in which a recess is formed in the door body and a lattice member formed by punching is fitted into the recess.

[0003]

[Problems to be solved by the device]

 Although the entrance door depends on the design of the house, it is generally required to be heavy, and when the door enters the entrance and the door is closed, the sound of the outside world is blocked and the independent space of the house is maintained. Is desired. The entrance door therefore separates the outside world from the personal life.

When the entrance door is reviewed from the above viewpoints, the door according to the above publication has a poor sound blocking effect because the member fitted in the recess is a lattice.

Therefore, the present invention was devised with the object of being able to form a flash door that is excellent in sound insulation and exhibits a heavy weight.

[0006]

[Means for Solving the Problems]

 According to the solution according to the present invention, a recess is provided on at least the outdoor surface of the door body, and a panel formed of a heavy body such as casting or stone is provided in the recess, and a space is provided between the door body and the door body in the middle of the entire surface. It is characterized in that it is fitted with a raised portion that holds the portion.

EXAMPLES The present invention will be described in detail. FIG. 3 shows the main part of the door body 1 in an exploded manner. The solid layer 3 of glass wool is packed in the aggregate 2, and the outer surface is covered with a surface material. 4 (see FIG. 1), the aggregate 2 is formed into a frame shape with an outer longitudinal bone 5 and an outer lateral bone 6 having a U-shaped cross section, and middle longitudinal bones are formed in the left and right parts inside the frame. 7 and 7, a middle upper bone 8 and a middle lower bone 9, and a plurality of intermediate horizontal bones 10 provided between both middle longitudinal bones 7, 7, 8 and the inferior-mid bone 9 are provided with step portions 11, respectively, and as shown in FIGS. 1 and 2, each step portion 11 ... Form a recess 12 in the central portion of the outdoor side surface of the door body 1. It is a thing. Although not shown, recesses may be provided on both front and back surfaces of the door body. Further, reference numeral 13 in FIG. 3 is a back plate, and 14 is a mail receiving port.

The panel 15 is fixed in the recess 12 of the door body 1. As shown in FIG. 1 and FIG. 2, the panel 15 is made of a heavy material such as a cast material or a stone material, which is excellent in sound insulation, and the central portion of the panel 15 is projected in a stepwise manner. A raised portion 16 is provided. A plurality of raised portions 16 may be provided on the horizontal strip as shown in FIG.

As shown in FIG. 1 and FIG. 2, the means for fixing the panel 15 to the door body 1 is such that the peripheral portion of the panel 15 is a step of middle longitudinal bones 7, 7, middle upper bones 8, middle lower bones 9. It is fixed to the parts 11 with screws 17 and when mounted in this way, since the panel 15 is provided with the raised portion 16 as described above, there is a space between the back surface of the raised portion 16 and the door body 1. 18 occurs. Further, the support fitting 19 is attached to the outer surface of the peripheral portion of the panel 15 by four rounds with the respective screws 17. The support fitting 19 has a U-shaped cross section, and ridges 20 are provided on both upright portions thereof, and a frame 21 is attached to the support fitting 19.

[0010]

[Effect of the device]

 The flush door according to the present invention has a panel with a raised portion fixed in a recess provided in the door body. In addition to the material of the panel, a space is maintained between the raised portion and the door body. As a result, the sound insulation performance is improved and it can be provided as a heavy-duty flash door.
