Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a support stand used for items that do not like vibrations, such as speaker boxes and record players.

<Prior Art> Conventional articles of this type are constructed to absorb vibrations from the outside by using elastic members provided at key points, such as springs or cushion bodies.

A support stand having such a structure has a problem in that an additional frequency is generated due to the elastic repulsive force of the elastic member, and this vibration wave is amplified in relation to the resonant frequency of the elastic member.

<Means for solving the problem> The present invention provides a support stand that supports the bottom surface of the above-mentioned article, and this support stand is a base that comes into contact with a support surface such as a floor or ground surface. A buffer block is placed and fixed on the base, and a buffer block is attached to the block and has a gap between it and the base, so that the block can be moved toward and away from the base while deforming the block. The block is equipped with a pedestal provided to be movable, and the block is made up of an elastic exterior body and a gel-like substance with a penetration depth of about 50 to 200 filled in the exterior body. be.

The penetration shown here is JIS K 2530-1976
− (50g load).

This standard concerns the petroleum asphalt penetration test method, and for samples with a penetration of 350 or less, the test is carried out with a load of 100g, but in the case of gel-like substances, the test is carried out with a load of 50g. ing.

<Function> Since the support base of the present invention is constructed as described above, when an article is placed on the pedestal, the buffer block supports the article in a state where it is crushed by the weight of the article.

When vibrations are applied to the article in this state from the floor surface, the vibrations are transmitted to the pedestal through the gel-like material of the buffer block and are therefore absorbed by the gel-like material.

In other words, when a gel-like substance with a penetration degree of 50 to 200 receives an external vibration wave, it deforms inelastically due to the vibration wave, so the vibration wave is attenuated and absorbed by the intermolecular frictional resistance generated at this time. Since this kind of gel-like material has vibration wave propagation characteristics similar to liquids, it rapidly and uniformly disperses the applied vibration waves and transmits them to the surroundings, thereby attenuating and absorbing the differentiated vibration waves. Become.

<Embodiment> The embodiment shown in FIG. The buffer block 30 has an exterior body 31 made of an elastic material, such as silicone rubber or polyurethane resin.
and a gel-like substance 32 filled in the exterior body 31, for example, containing silicone resin as a main component, and the gel-like substance 32 has a penetration degree of 50 to 200, preferably a penetration degree of 50 to 200. 100-200 have been selected.

The buffer block 30 is connected to the base 20 and the pedestal 4.
For example, it may be fixed using an adhesive, but for example, as shown in FIG. A locking means such as 41 or the like may be provided and the locking may be performed using this locking means.

The pedestal 40 is attached to the buffer block 30 and is attached to the buffer block 3 by a folded edge 42.
0, and such a configuration may be applied to the base side by providing a folding edge 22 on the base 20 as shown in FIG.

The buffer block 30, as shown in FIG.
The exterior body 31 may be a hollow sphere with a desired diameter, for example, about 50 mm, and may be filled with a gel-like substance. In this case, silicone resin, which is a raw material, may be filled in the elastic sphere in advance. After injecting the liquid, the sphere may be heated to gel the silicone resin liquid inside.Toray Silicone CY-52264 Gel manufactured by Toray Silicone Co., Ltd. is available as a raw material for such a gel-like substance.

Since the supporting stand of the present invention is as described above, for example, when an article 50 such as a speaker box is placed on the pedestal 40 as shown in FIG.
As shown by the chain lines in FIGS. 2 and 3, the pedestal 40 is crushed and strained, allowing the pedestal 40 to descend, and comes to rest when the load of the article and the supporting force of the buffer bollock 30 are balanced.

The repulsive force of the buffer block 30 against the static pressure is determined by the selection of the penetration degree of the gel material 32 and the
Therefore, the buffering effect of the gel material 32 is performed in a state where a predetermined repulsion force is generated.

When a vibration wave is applied to the gel-like material 32 in such a deformed state, the gel-like material 32 is deformed inelastically by the vibration wave, and as described above, the vibration energy is rapidly and uniformly dispersed. Since the vibration waves are differentiated, the vibration waves are attenuated and absorbed without generating separate vibration components.

<Effect of the invention> Since the present support is as described above, the basic resistance or strength against static pressure can be obtained mainly from the structure of the exterior body 31, and the applied vibration waves can be Whether this comes from the pedestal or the base, it is absorbed by the deformation of the gel material 32 with almost no elastic repulsion.

Therefore, the present support has the effect that vibration waves from the outside are quickly absorbed without generating separate vibration waves within the buffer block.
