Description

[Detailed Description of the Invention] The present invention relates to sound insulating furniture with excellent sound insulating properties suitable for constructing storage partition walls.

It is generally well known to assemble furniture to form storage units. If such a storage unit is arranged in the center of a room or the like to form a partition wall that partitions a room, each piece of furniture will be useful as it will have a storage function as well as a partition function.

However, when a storage partition wall is constructed by assembling furniture like this, although it may be possible to visually separate the rooms, there is a problem with sound insulation, as the partitioned rooms can hear each other. . In other words, conventional furniture uses hardboard or plywood for the backboard.
A single piece of particle board or a combination of these is used, and there are gaps between furniture panels or between furniture panels and interior walls, resulting in inadequate sound insulation as a partition. It was hot.

The present invention has been developed in view of these points, and is designed to reduce the leakage of sound from furniture backboards, gaps between furniture, and between furniture and indoor surfaces, and to construct a storage partition wall. The purpose of this invention is to provide suitable sound-insulating furniture.

To achieve this purpose, the configuration of the present invention is such that the back plate is made of a plate-like body pasted or filled with a sound insulating material, and the outer peripheral surface of at least one of the left and right side plates, the upper plate, and the lower plate is A protrusion is provided that is substantially parallel to the back plate. As a result, the sound insulation performance of the furniture backboard is improved by the sound insulation material, and the ridges reduce the leakage of sound from the gaps between furniture and the gaps between the furniture and the interior wall surface.

Here, the sound insulation material, that is, the sheet-like material to which the back plate is attached, is generally called a sound insulation sheet, and the sound insulation sheet is a sheet of rubber or synthetic resin filled with metal powder, inorganic filler, etc. This sound insulation sheet can be used as a surface layer or middle layer of a wooden board such as plywood, particle board, hardboard, or an inorganic board such as gypsum board or calcium silicate board. voids in a panel attached to a panel, a plate filled with metal powder, inorganic filler, etc. when manufacturing the above wooden or inorganic plate, or a flat panel combined with the above wooden or inorganic plate. It is constructed by a single panel filled with the above-mentioned sound insulation sheet or inorganic fibrous material, or a composite plate thereof.

Furthermore, it is preferable that the protrusions provided on the outer circumferential surfaces of the side plates, top plate, and bottom plate be made of an elastic material such as rubber, synthetic resin foam, or soft synthetic resin; A rigid body may be used in the case where there is a groove in the part where the protrusion fits into the groove. In addition, the protrusions can be directly attached to the outer circumferential surfaces of the side plate, upper plate, and lower plate, or grooves may be provided in advance on the outer circumferential surfaces, and elastic or rigid rod-shaped objects may be fitted into the grooves. A method of assembling the furniture is to form a protrusion on the furniture and fit the protrusion into the groove of another piece of furniture that comes into contact with the furniture. In particular, when assembling the furniture by fitting them into the grooves, the close contact between the panels of furniture that come into contact with each other and the fitting of the protrusions provide excellent sound insulation, and if a rigid body is used for the above fitting, the furniture This is preferable because the fixation between the parts is also strong. In addition to the abutment between furniture pieces, it is also possible to employ the above-mentioned arrangement of abutment between furniture pieces for the size adjustment material and fixing material for the gap between the furniture and the indoor surface.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 shows a case where a storage partition wall is constructed using box-shaped furniture as sound-insulating furniture according to the present invention,
A is box-shaped furniture, which is a combination of units with a unified depth of 450 mm, and width and height set in multiples of 450 mm. A plurality of these units are stacked and arranged horizontally to form partition walls that separate rooms. arranged to configure. The back plate 1 of the furniture A is
As an example, as shown in FIG. 2, decorative plywood 11, 11 with a thickness of 2.7 mm, for example, as a facing material on both sides,
Thickness 1.2 affixed to the back side of one decorative plywood 11
mm, specific gravity 2.0 rubber sound insulating sheet 12 and crosspiece 13 interposed and glued between both of the decorative plywood boards 11, 11.
and rock wool granular cotton 14 filled between the two decorative plywood boards 11, 11, and has a total thickness of 20 mm. Furthermore, as shown in FIG. 3, the left and right side panels 2, 2, the upper panel 3, and the lower panel 4 of the furniture A are made of decorative plywood 15, 15 with a thickness of 2.7 mm as facing materials on both sides, and It consists of a flat panel with a total thickness of 15 mm, which is composed of plywood boards 15, 15 and a crosspiece 16 bonded between them, and in the center of the panel's outer circumferential surface, parallel to the back plate 1, there is a plate having a depth of 5 mm and a width of 10 mm. A concave groove 5 is formed.

The furniture A is first installed on the floor with one side plate 2 in contact with the wall. At that time, an 8 x 20 mm rubber rod is fitted into the concave groove 5 of the side plate 2 that contacts the wall to form a protrusion, and the protrusion (rubber rod) is installed so as to be pressed against the wall. be done. Next, as shown in FIG. 8, rubber rods 6 are placed in the grooves 5 of the upper plate 3 and other side plates 2 of the furniture A.
are fitted to form a protrusion 7, and the storage partition wall is assembled in sequence so that each protrusion 7 of the top plate 3 and side plate 2 fits into the groove 5 of another furniture A. Constructed. Incidentally, the gap between the furniture A and the wall and ceiling is filled by placing a size adjusting material and then inserting a rubber rod into the space.

Therefore, sound insulating furniture A configured in this way
has an excellent sound insulation performance because a sound insulation sheet 12 (sound insulation material) is arranged on the back plate 1 and rock wool granular cotton 14 is filled between the decorative plywood boards 11 and 11. The protrusions 7 provided parallel to the backboard 1 prevent sound from leaking between the furniture A and between them and between the furniture A and the indoor wall, thus providing good sound insulation as a storage partition wall. I can demonstrate it. Now, specifically, a case where a partition wall is constructed using the sound insulating furniture A having the structure as in the above embodiment (an example of the present invention), and a plywood 11' whose facing material is 2.7 mm on both sides as shown in FIG. 4, 11′ and total thickness 20mm
When a partition wall is constructed using conventional box-shaped furniture constructed of flat panels (Comparative Example 1),
Plywood 1 with 4mm surface material on both sides as shown in Figure 5
When the sound insulation performance was measured for the case where the partition wall was constructed using a partition wall panel composed of pillars 18 with a diameter of 1" and 11" and a total thickness of 90 mm (Comparative Example 2), it was found that The reduction was 10 dB in Comparative Example 1 and 22 dB in Comparative Example 2, whereas the reduction was 25 dB in the present invention. It can be seen that the sound insulation performance is superior by using the method.

In addition to the structure shown in FIG. 2, the structure of the back plate 1 of the furniture A may be as shown in FIGS. 6 to 7. That is, the back plate 1a shown in FIG.
A sound insulating sheet 12' is arranged in the middle part of the plate-like object 17, and the back plate 1b shown in FIG.
A sound insulating sheet 12' is arranged on one surface of the surface layer.

As described above, according to the sound insulating furniture of the present invention, by assembling the furniture, it is possible to provide a storage partition wall with excellent sound insulating properties, storage properties, and decorative properties.
