Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to storage furniture that is used by being partitioned and used in an office or the like.

[Prior Art] In offices and the like, it is often the case that a plurality of storage furniture are arranged to partition the space.

Thus, the storage furniture used in such a manner has its back panel exposed to the office space, unlike furniture arranged exclusively along the wall surface. for that reason,
An exterior plate is provided on the back panel of this type of storage furniture to prevent the reinforcing member and the like from being exposed.

[Problems to be solved by the invention] However, since the exterior panel of the back panel in this type of storage furniture has a vast and flat metal surface, it has the property of reflecting sound well on the surface. There is. Therefore, there is a problem in that the voices and sounds generated from so-called OA devices are less likely to be attenuated, which hinders the quietness of offices or the like and promotes noise.

In addition, since the exterior plate of such a back panel has a relatively large area, a so-called sticking phenomenon and a propeller phenomenon are likely to occur. In other words, if the central portion of the exterior plate extends beyond the peripheral portion, the central portion will be pestle in the thickness direction. Conversely, if the peripheral edge extends beyond the central portion, the entire exterior plate will be twisted like a propeller. . Therefore, there is a problem that it is difficult to flatten the surface of the exterior plate with good appearance and accuracy.

An object of the present invention is to solve the above-mentioned problems all at once while improving the convenience for indoor use.

[Means for Solving the Problems] The present invention adopts the following configurations in order to achieve the above-mentioned objects.

That is, the storage furniture according to the present invention is an indoor storage furniture in which a three-dimensional louver is provided on the exterior plate of the back panel and a sound absorbing material is arranged inside the exterior louver, and the exterior rim is provided on the periphery of the exterior plate. An inward bent portion formed by bending a sheet metal material to the inner surface side is integrally formed, and a peripheral edge portion of the surface of the exterior plate is formed into a flat shape, and an upward cut is formed in an inner portion of the peripheral portion. A louver is integrally formed by opening a vent hole between each of a plurality of bulging portions that protrudes toward the inner surface and a plurality of flat portions that are flush with the peripheral edge portion. It is characterized in that a cloth material is attached to the.

[Operation] With such a configuration, when sound is emitted in the space facing the back panel, the sound is emitted inside the back panel from the ventilation hole of the louver formed in the exterior plate of the back panel. It propagates and is absorbed by the sound absorbing material arranged in that portion. Therefore, even if the exterior plate is present facing a space such as an office, it is possible to prevent sound from being repeatedly reflected on the metal surface, and to reduce the noise level in the room.

In particular, since the louver has a shape such that its upward cut protrudes toward the inner surface side of the exterior plate, and the sound absorbing material has a cloth material attached to its surface, the louver is directed upward. The sound absorbing material is caught on the tip of the cut. Therefore, it is possible to prevent the sound absorbing material from sliding down without adhering the sound absorbing material to the exterior plate. As a result, the surface of the sound absorbing material will not be hardened and deteriorated by the adhesive, and most of the sound absorbing material will not adhere to the face plate and the sound absorbing effect will not be diminished. Therefore, the sound absorbing performance of the sound absorbing material can be fully utilized, and the maximum sound absorbing effect can be expected.

Further, when the three-dimensional louver is integrally provided on the exterior plate such that the flat surface portion and the peripheral portion of the exterior plate are flush with each other, the above-described peking phenomenon and propeller phenomenon can be alleviated.
That is, if a three-dimensional louver is formed on the face plate, the rigidity of the face plate is increased, so that the sticking in the thickness direction is effectively suppressed. Furthermore, since the difference in elongation between the central portion and the peripheral portion of the face plate is absorbed by the opening portion of the louver, the propeller phenomenon is also alleviated.

In addition, since it is possible to eliminate a portion protruding from the surface of the exterior plate, clothes or the like are not caught and damage to them can be prevented. That is, in the present invention, the plane portion of the three-dimensional louver formed on the exterior plate is flush with the peripheral edge portion, and the bulging portion bulges inward of the plane portion. In addition, the peripheral edge of the exterior plate is integrally bent toward the inner surface to form an inward bent portion. Therefore, it is possible to completely eliminate the members protruding outward from the peripheral portion and the flat surface portion of the exterior plate,
The cut edges of the sheet metal material will not be exposed to the outside.
Therefore, even if the clothes of a walking human may come into contact with the surface of the exterior plate, the clothes are not caught by the face plate and are not damaged. Further, with such a structure, even when the surface dirt of the face plate is wiped off with a cloth or the like, the cloth or the like is not caught and the cleaning operation can be performed smoothly and quickly.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

As shown in FIGS. 1 and 2, this storage furniture is a box-shaped one in which a side panel 2 and a back panel 3 are erected on a base 1 and a top plate 4 is provided on the side panel 2.
A door 5 is provided in the front opening so as to be openable and closable.

The back panel 3, as shown in FIGS. 2 and 3,
A hollow wall-shaped body formed by mutually combining an inner plate 6 made of sheet metal having an outward bent portion 61 on the peripheral edge and an outer plate 8 made of sheet metal having an inward bent portion 81 integrally formed on the peripheral edge. Is. And
The louver 7 is attached to the inner portion 83 of the exterior plate 8 excluding the peripheral portion 82.
Is integrally provided by press working, and the sound absorbing material 9 is sandwiched between the exterior plate 8 and the interior plate 6.

As shown in FIG. 4, the louver 7 is a three-dimensional one in which a horizontally extending upward cut 71 is projected toward the inner surface 84 side of the exterior plate 8, and the bulging portion 72 inwardly and the peripheral portion are formed. Downward ventilation holes 74 are opened in multiple stages between the 82 and the flat surface portion 73.

The sound absorbing material 9 is mainly composed of glass wool, rock wool or the like formed in a thick sheet shape, and a cloth material such as a gauze cloth (coarse plain woven cloth) 91 is attached to the surface of the sound absorbing material 9 by partial adhesion or stitching. I am setting it up. The thickness W of the sound absorbing material 9 is determined by the upward cut of the louver 7 in the exterior plate 8.
It is set to be slightly larger than the separation distance L between the tip edge 71a of 71 and the inner surface 62 of the interior plate 6. However, the sound absorbing material 9 wrapped in the cheesecloth 91 and the exterior plate 8 are not bonded.

With such a configuration, when sound is emitted in the space on the side of the exterior plate 8, the sound is propagated from the ventilation hole 74 of the louver 7 formed in the exterior plate 8 to the inside of the exterior plate 8. As a result, the sound absorbing material 9 arranged in that portion is absorbed and converted into heat energy. Therefore, even if the exterior plate 8 of the back panel 3 is present facing a space such as an office, it is possible to prevent the sound from being repeatedly reflected on the metal surface, and the noise level in the room is reasonably effective. Can be reduced to

The outer plate 8 has a peripheral edge portion 82 and a flat surface portion of the louver 7.
73 is flush with the bulging portion 72 of the louver 7 so as to project to the inner surface side of the exterior plate 8. Therefore, a member that projects outward from the outer surface of the peripheral edge portion 82 and the flat surface portion 73 is not provided. It can be completely eliminated. Moreover, since the ventilation hole 74 of the louver 7 is formed between the upward cut 71 of the bulging portion 72 projecting inward and the lower edge of the flat portion 73, the outer plate 8 is formed by pressing. Even if formed integrally, the upward cut 71 and the vent hole 74 do not face outward. Further, since the peripheral edge of the exterior plate 8 is integrally bent toward the inner surface side to form the inward bent portion 81, the cut edge of the sheet metal material is exposed in a state of protruding outward from the peripheral portion 82. Also disappears. Therefore, even if the clothes of a walking person slide on the surface of the exterior plate 8, the clothes are not caught by the exterior plate 8 and are damaged. Further, if such a thing is used, even when the surface dirt of the exterior plate 8 is wiped off with a cloth or the like,
Cleaning work can be carried out smoothly and quickly without catching cloths.

In addition, in such a case, the cold cloth 91 attached to the surface of the sound absorbing material 9 is hooked at the tip edge 71a of each upward cut 71 of the louver 7 protruding toward the inner surface 84 of the face plate 8. Therefore, the sound absorbing material 9 does not slide down even though the exterior plate 8 and the sound absorbing material 9 are not adhered by an adhesive or the like. If the sound absorbing material 9 is adhered to the exterior plate 8 using an adhesive, the surface of the sound absorbing material 9 may be hardened or deteriorated to make it difficult to obtain a sufficient sound absorbing effect. If it is not necessary to bond 9 to the exterior plate 8, such an inconvenience is not caused, and not only the assembling work can be simplified, but also an excellent effect that sound absorbing performance can be improved is obtained. And this louver 7
Has a three-dimensional structure, a space S communicating from the outside to the inside via a ventilation hole 74 is formed above the upward cut 71, and the sound absorption that is not restrained by the adhesive or the like in the space S. The material 9 faces. Therefore, also from this point, high sound absorbing performance can be expected.

In other words, the cutout louver 7 protruding upward to the inner surface of the outer casing 8 is provided on the outer cover 8, and the distance L between the leading edge of the cut and the inner surface of the inner cover 6 is the thickness of the sound absorbing material 9. By installing it smaller than the dimensions, the sound absorbing material 9 is attached to the tip of the cut end.
Even if the sound absorbing material 9 is not adhered to the exterior plate 8, the cloth attached to the surface of the can be prevented from sliding down. Furthermore, unless an adhesive is used on the surface of the sound absorbing material 9 on the exterior plate 8 side, the surface of the sound absorbing material 9 is hardened and deteriorated by the adhesive, or most of the sound absorbing material 9 adheres to the face plate. The sound absorbing effect is not destroyed, and the sound absorbing performance of the sound absorbing material 9 can be fully utilized, so that the maximum sound absorbing efficiency can be expected.

Further, when the three-dimensional louver 7 is formed on the exterior plate 8, the louver 7 also performs a rib-like action, and the exterior plate 8
It is possible to effectively prevent the occurrence of the sticking phenomenon by improving the rigidity of the. Further, when the louver 7 is formed, the materials are separated from each other at the vent hole 74 portion of the louver 7, so that there is a difference in the elongation of the material between the peripheral portion 82 of the face plate 8 and the inner portion 83 thereof. However, the difference in elongation is absorbed by the presence of the vent holes 74. Therefore, the problem that the exterior plate 8 is deformed like a propeller can be eliminated.

The shape of the louver may be as shown in FIG. That is, this louver 107 has the inwardly bulging portion 1
Bend the upper end 172a of 72 further inward to make an upward cut.
The front edge 171a of the 171 is sharpened. With this configuration, the cloth material 191 attached to the surface of the sound absorbing material 109 can be more easily hooked to the upward cut 171. Therefore, it is possible to more reliably prevent the sound absorbing material 109 from sliding down. .

Further, the structure of the back panel is not limited to the one described above, and various modifications can be made, for example, using an interior plate having a vent hole.

Further, the height of the stored furniture may be about the height of a person's waist or the height of eyes, or may reach the ceiling.

[Advantages of the Invention] Since the present invention has the above-described configuration, when the office or other space is partitioned, the exterior panel having the louver of the back panel faces the defined space. become. As a result, it is possible to effectively absorb the sound emitted in the space, and it is possible to effectively reduce the noise level in the space effectively. In particular, if the louver is shaped as described above and a cloth material is attached to the surface of the sound absorbing material, the cloth material catches on the upward cut of the louver, so that the sound absorbing material is attached to the exterior plate. It is possible to prevent it from slipping without adhering to the inner surface of the. Therefore, the problem that the surface of the sound absorbing material is hardened in a wide range by the adhesive and the sound absorbing effect is lowered can be solved.

In addition to this, by providing the louver, the rigidity of the exterior plate can be increased, and the adverse effect due to the difference in the elongation rate of the material can be mitigated, resulting in a good appearance without deformation.

Moreover, since the louver is integrally formed on the exterior plate having the inwardly bent portion integrally on the peripheral edge, and the flat surface portion and the peripheral edge portion of the exterior plate are formed flush with each other, the louver does not have anything on the surface of the exterior plate. It is possible to prevent the parts from protruding and the cut of the exterior plate material to exist outward. Therefore, even if clothes of a walking person come into sliding contact with each other, it is possible to prevent the clothes from being caught by the exterior plate and being damaged. Therefore,
It can be suitably used in a place where a person approaches and moves in front of it, that is, in a corridor or an office wall. Further, even when the surface of the exterior plate is wiped off with a cloth or the like, the cleaning work can be performed smoothly and quickly without catching the cloth or the like.
