Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack for storing audio equipment or video equipment.

[0002]

2. Description of the Related Art There is a rack for accommodating audio / visual equipment as shown in Japanese Utility Model Laid-Open No. 1-95893, in which all or a part of a top plate, a shelf plate, a bottom plate, and a side plate is one.
It is formed of a resin plate composed of an epoxy resin, a polyamide resin, and an inorganic filler having a vibration loss coefficient of 0.02 or more at 0 to 30 ° C. (For example, Japanese Utility Model Laid-Open No. 3-27783).

[0003]

Vibration is generated from a motor or a speaker incorporated in the audio / video equipment. However, the conventional storage rack for audio / video equipment is insufficient in absorbing and attenuating the vibration. In some cases, all or a part of the top plate, shelf plate, bottom plate, and side plate of the storage rack may cause resonance with the vibration, and there is a problem that original sound quality and images cannot be sufficiently reproduced.

[0004] Further, the conventional storage rack is also insufficient to block vibration transmitted from the floor to the storage rack, and has a problem of adversely affecting reproduced sound quality and video.

Accordingly, the present invention has been made to solve such a problem, and it is intended to absorb and attenuate vibrations generated from audio / video equipment, and to block vibrations transmitted from the floor, thereby reducing the original vibration. Sound that can reproduce sound quality and video well
A video equipment storage rack is provided.

[0006]

The audio / video equipment storage rack of the present invention has a top plate, a shelf plate, and a bottom plate formed of a vibration damping material, and the top plate, four corners of the rectangular frame portion of the frame body, A pointed support member for supporting the shelf plate and the bottom plate is provided, and a pointed leg is provided at the bottom of a column of the frame, and the vibration damping material includes an organic material between a pair of hard boards. Any one of melamine, acrylic, and vinyl chloride is formed on the surface of a hardboard molded body obtained by press-molding with an adhesive layer in which 25 to 300 parts by weight of metal powder is added to 100 parts by weight of a binder. Is formed by coating.

(1) Hard board As the hard board, Japanese Industrial Standard "Hard fiber board" A
Those conforming to 5907 are used. (2) Organic binder As the organic binder, one or more of an epoxy resin, a polyurethane resin, an unsaturated polyester resin, a polyacrylester resin, an amino resin, a urea resin, and a phenol resin are used. (3) Metal Powder As the metal powder, one or more metal powders of aluminum, copper, brass, zinc, titanium, stainless steel, nickel, steel, cast iron and alloys thereof are used, and preferably 300 mesh or less. Organic binder 10
25 to 300 parts by weight is added to 0 parts by weight.
When the amount exceeds the weight part, the bulk specific gravity of the molded hardboard becomes large, and the flexibility is lost. (4) Coating layer Any one of melamine, acrylic, and vinyl chloride is used as the coating layer. The coating layer improves sound quality, improves the appearance, and particularly uses easily oxidizable iron powder. In this case, it is possible to prevent oxidation and to prevent poor appearance over time.

[0008]

[Function] Vibration generated from audio / video equipment is transmitted to the top plate, shelf plate and bottom plate, respectively, absorbed by the vibration damping material forming each plate, and the vibration energy is converted into heat energy and dissipated. . The vibration transmitted from the floor to the frame is
Propagation to the frame is substantially blocked by the pointed legs provided at the bottom of the column support.

[0009]

1 and 2 show an audio / video equipment storage rack according to the present invention, which is formed of a rectangular parallelepiped frame 1, a top plate 2, a shelf 3 and a bottom plate 4, and the frame 1 is rectangular. A pointed support member 5 for supporting a top plate 2, a shelf plate 3, and a bottom plate 4 is provided upright at four corners of the rectangular frame portion 1a, and a bottom portion of the column 1b. Is provided with a pointed leg 6.

The top plate 2, the shelf plate 3 and the bottom plate 4 are formed of a damping material, and the damping material is composed of a pair of hard boards (T350).
An adhesive layer containing 200 parts by weight of cast iron powder (300 mesh) with respect to 100 parts by weight of phenol resin was interposed therebetween, and the surface of a hard board molded body (thickness: 11 mm) obtained by pressure molding was thickened. It is a vibration damping plate (12 mm thick) formed by sticking a melamine sheet having a thickness of 0.5 mm.

Audio / video equipment is appropriately placed on the top plate 2, the shelf plate 3, and the bottom plate 4, and the vibration generated from the equipment is:
The vibrations are transmitted to the upper plate 2, the shelf plate 3 and the bottom shelf 4, respectively, and absorbed by the vibration damping material forming the plates 2, 3, and 4, and the vibration energy is generated by mutual friction between the phenol resin and the cast iron powder. Dissipates into heat energy and dissipates.

The vibration transmitted from the floor to the frame 1 is substantially blocked by the pointed legs 6 provided at the bottom of the frame 1, and the top plate 2 and the shelf Since the plate 3 and the bottom plate 4 are supported by the pointed support member 5, and the frame 1 is erected on the floor by the pointed legs 6, there is no generation of noise due to backlash.

[0013]

According to the present invention, vibrations generated from audio / visual equipment are absorbed and significantly attenuated, and vibrations transmitted from the floor to the rack are substantially cut off. Since the bottom plate and the frame are prevented from rattling, the original sound quality and image can be reproduced well by a rack having a simple configuration without any electrical improvement of the audio / video equipment system. The commercial value can be improved by applying various designs.
