Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piano,

More particularly, the present invention relates to a pedestal for preventing vibration of a piano, and more particularly, to a pedestal for preventing the vibration of a piano, The present invention relates to a support for preventing vibration of an automobile.

In general, a piano used for a performance in a home or a performance place is provided with a wheel, that is, a caster, at the lower end of the leg to prevent the mobility from being reduced due to heavy weight.

If the casters are installed at the lower ends of the piano legs as described above, great convenience is provided in the process of moving the piano.

However, there is a problem that the piano flows on the floor surface due to the characteristics of the structure of the caster, or the sound or vibration of the piano is transmitted to the floor through the caster.

Especially, in a densely populated residential space such as an apartment, it also becomes a main cause of environmental noise.

Therefore, a pedestal (a pedestal, a pedestal plate, etc.) for a piano castor is used to prevent the flow of the piano on which the castor is mounted and prevent the direct contact with the floor surface, The lower surface is flat and flat.

As a prior art having such a structure, a 'noise and vibration reduction pedestal' disclosed in Korean Patent Registration No. 10-0901685 is disclosed.

The prior art includes a main body having a receiving portion recessed in an upper portion thereof, a lowering member inserted into the receiving portion, and a cover covering the lowering member, Is formed, which is capable of easily reducing noise and vibration, preventing damages between residents due to the interlayer noise, and protecting the reduction member by the cover for a long period of time.

However, in the prior art, there is a problem in that the cost due to an increase in the number of parts is increased, and when the casters are provided on the piano legs, the casters can not be tightly supported by the reduction members, have.

Therefore, there is a need for a pedestal for an efficient piano caster which can reduce manufacturing cost due to a simple structure, but can prevent vibration or sound from being transmitted through the floor by providing additional features.

Korean Patent Registration No. 10-0901685, noise and vibration reduction pedestal.

The object of the present invention is to provide a pedestal for preventing vibration of a piano which can minimize the phenomenon that sound or vibration generated in the piano is transmitted through the floor by allowing the lower portion of the castor installed on the piano bridge to be closely supported .

In order to achieve the above object, the present invention provides a pedal for preventing vibration of a piano which can receive a castor installed on a piano bridge, wherein the piano is provided with a flat supporting surface at the bottom so as not to slip close to the bottom surface, Shaped support body made of rubber or silicon material having a circular installation groove formed therein; And an anti-vibration support member made of rubber or silicone material having a metal plate formed therein, wherein the support groove is formed in an upper portion of the support body, And the support groove formed in the vibration-proof support member is formed to be circularly recessed so that the lower portion of the caster can be closely contacted to the support groove regardless of the position of the caster.

And a plurality of contact protrusions are formed on a bottom surface of the vibration-proof support member.

And the support surface of the support body is formed with concentric support protrusions.

The present invention is characterized in that a metal plate is provided inside a vibration-proof support member in which a lower portion of a castor installed on a piano bridge is tightly supported, and the vibration-proof support member is installed inside a support body to reinforce the strength of the vibration- The vibrating support member and the receiving body can minimize the phenomenon that vibration and sound are directly transmitted to the bottom surface.

In addition, in the present invention, since the support groove, in which the lower portion of the caster installed on the piano leg is closely contacted and supported, is formed so as to be circularly grooved so that, regardless of the orientation of the caster, So that it can be easily installed.

1 is an exploded perspective view of a support for preventing vibration of a piano according to the present invention,
2 is an exploded perspective view showing the bottom of the anti-vibration support base according to the present invention,
3 is a cross-sectional view showing the structure of the anti-vibration support member according to the present invention,
Fig. 4 is a perspective view showing a state in which a caster is tightly supported on a support for anti-vibration according to the present invention. Fig.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in the drawings, the anti-vibration support base includes a support body 110 and a vibration-damping support member 120, which can support the caster 12 installed on the piano bridge.

The support body 110 has a flat support surface 112 at its lower part in contact with the bottom surface so as not to slip, and a circular installation groove 114 in which only an upper portion is opened is formed in the support body 110.

At this time, it is preferable that the support protrusions 112a are formed concentrically on the support surface 112, and the transmission of vibration and the like to the bottom surface by the support protrusions 112a can be minimized.

The support protrusions 112a are formed concentrically so that the flat support surface 112 provided on the bottom surface of the support body 110 is supported by the support protrusions 112a on the bottom surface by the weight of the piano It is possible to obtain a simultaneous effect of preventing noise and preventing slipping due to tight friction with the bottom surface.

The support body 110 is preferably formed in a disc shape made of rubber or silicon.

The vibration-proof supporting member 120 is inserted into and fixed to the mounting groove 114 of the receiving body 110 so that the lower portion of the caster 12 mounted on the piano die is closely contacted.

The vibration-proof support member 120 is formed with a support groove 124 in which a lower portion of the caster 12 can be closely contacted.

At this time, the support groove 124 is formed to be recessed in a circular shape so that the lower portion of the caster 12 can be closely supported to the support groove 124 regardless of the position of the castor 12 in any direction.

The vibration-proof supporting member 120 may be made of rubber or silicone.

In addition, a metal plate 126 is provided inside the vibration-proof support member 120 to reinforce the vibration-proof support member 120 made of rubber or silicone. That is, since the metal plate 126 is installed inside the vibration-proof support member 120, the vibration-proof support member 120 is prevented from being deformed and damaged by the weight of the piano.

It is preferable that a plurality of contact protrusions 128 are formed on the bottom surface of the vibration-proof supporting member 120 and the contact protrusions 128 are closely contacted with each other in the mounting groove 114 of the receiving body 110 It is possible to effectively prevent the vibration and the sound of the piano from being transmitted to the floor surface.

According to the present invention, the caster 12 installed on the piano leg is brought into contact with the vibration-proof support member 120 provided inside the support body 110, so that the vibration-proof support member 120 and the support body 110 Vibration and sound are prevented from being transmitted to the floor, thereby preventing damage to residents due to the interlayer noise.
