Description

[Detailed Description of the Invention] The present invention relates to a vibration-proof rubber stand that absorbs solid-borne sound generated when a piano is played.

Conventionally, the vibration-proof rubber stands that have been commonly used are trapezoidal as shown in Fig. 1 or cylindrical as shown in Fig. 2. caster 2
However, if the height of the rubber stand 3 was made to be more than 30 pieces in order to achieve a vibration-proofing effect, it would be difficult to operate the piano pedals.
There was a grudge that he could not support the piano, which was close to his own, and he lacked stability.

Furthermore, since the contact point between the rubber base 3 and the piano caster 2 is a so-called point contact, piano vibrations are transmitted directly to the bottom surface, making it impossible to obtain satisfactory vibration-proofing and sound-proofing effects.

Further, in the latter case, since the piano casters 2 are dropped into the hollow part 5, the piano cannot be stored unless the piano is lifted up to the height of the casters 2, which poses a problem in handling.

This invention was made in view of the current situation, and has a hardness of approximately 6.
To provide a vibration-proof rubber stand which can support a caster in a floating state by providing a notch capable of accommodating a part of a piano caster on one side end face of a natural or synthetic rubber block of 0 and shining directly on the piano top stand. The purpose is to

Hereinafter, details will be explained using an example shown in the drawings.

The anti-vibration rubber base 10 is provided with a notch 11 on the 5t'C1 side end face as shown in FIG. It has a height Hl higher than H2, and the upper and lower end surfaces 12.13 are flat and parallel.

In this example, a block of synthetic or natural rubber is used as the vibration-proof rubber 10, but a block formed by laminating plates may also be used.

Further, although the lower end surface 13 is larger than the upper end surface 12, it may be a rectangular parallelepiped, a cube, a cylinder, a prism, or the like.

Since the anti-vibration rubber base 10 configured in this way has a notch 11 at the negative end, the piano is floated a little higher than the height H of the anti-vibration rubber base 10, and the piano casters 2
is accommodated in notch 11, and there is a slight notch 1 in side 5.
Installation is completed by simply moving in one direction.

For this reason, the heavy labor of lifting the piano casters 2 at a height 1 greater than the height H2 of the piano casters 2 + the height of the vibration isolating rubber base, as in the conventional anti-vibration rubber base, and the adverse effects on the piano during handling are drastically reduced.

Furthermore, since the end surface 12 that receives the piano base 1 is larger than that of conventional vibration-proof rubber, it is easier to install, increases stability, and at the same time doubles the effect of diffusing vibrations.

Further, since the structure is simple, it can be mass-produced at low cost.
