Description

The prop for noise and impact vibration absorbing

The present invention relates to a noise and vibration reduction pedestal, and in particular, by placing on a floor surface on which a lot of noise, such as a piano or a washing machine, is placed, thereby reducing the noise and vibration generated when using the piano, a washing machine, etc. It relates to a noise and vibration reducing pedestal to prevent damage caused by vibration.

In general, in the floor structure of high-rise buildings or apartments, houses, etc., the upper floor is divided with the concrete slab in between.

Accordingly, when an impact is applied to the floor, the floor slab flexes and vibrates, and a floor shock sound is generated in which the vibration is radiated as sound in the air, and is transmitted to the lower floor.

The impact sound is classified into a light impact sound and a heavy impact sound, and the light impact sound is an index for evaluating how pronounced in the floor directly below the floor due to a drop of a small object or a shock applied to the floor when the furniture is moved. The noise consists of

On the other hand, heavy impact sounds are dull sounds such as children playing, and are noises composed of low range sounds of 50 decibels or less.

The impact sound, such as the above, is one of the high pollution that has a great disruption to residential life or work and has a serious psychological and physical impact on people.

In particular, there are many causes of noise that may cause problems among residents, such as a piano sound generated in a general home or a noise generated in an operation of a washing machine.

Therefore, in order to prevent the generation of noise, by placing a support plate on a fixed leg, such as a piano or a washing machine, to reduce the vibration transmitted to the outside through a fixing leg, such as a piano or a washing machine, one example of the prior art of Figures 1a and 1b Referring to the description as follows.

A first fixing plate 100 having a predetermined thickness and having a recessed portion 120 formed therein, and a second fixing plate 200 installed at one surface thereof in contact with the first fixing plate 100, and the second fixing plate 100. In the sound absorbing support plate comprising a bottom plate 600 attached to the fixed plate 200 to be in contact with the floor, the sound absorbing material 160 is installed in the recessed portion 120 of the first fixing plate 100, A protrusion 140 is formed on a rear surface of the first fixing plate 100 opposite to the recess 120 to contact the second fixing plate 200, and between the second fixing plate 200 and the bottom plate 600. Lower rubber plates 300 and 500 are interposed.

However, in the conventional sound absorbing plate, the number of parts constituting the sound absorbing plate and the assembly process is large, causing a cost increase, a lot of work time is required, and there is a difficulty in bonding to a plurality of parts.

In addition, the adhesive parts are easily separated when used, and the sound absorbing plate is damaged, and thus there is a problem in that noise and vibration are not reduced.

An object of the present invention is to solve the problems as described above, to prevent the sound-absorbing part is damaged by continuous use, easy to manufacture, reducing the number of parts to reduce the noise and vibration to reduce the working time To provide a pedestal.

In order to achieve the above object, the noise and vibration reducing pedestal of the present invention is a pedestal for supporting furniture, home appliances, or musical instruments, the main body having an accommodating recess in which an upper portion is recessed, a reducing member inserted into the accommodating portion, and the reducing member. It is characterized by consisting of a covering cover.

In addition, the lower surface of the cover to prevent the flow of the cover Fixed protrusions It is characterized by.

In addition, the cover is characterized in that formed in a concave curved surface.

In addition, the reducing member is characterized in that formed of rubber or silicon.

In addition, the silicon is characterized in that it is formed by inserting into a plastic bag.

In addition, the reducing member is characterized in that formed by receiving the liquid in the bag in which the liquid is accommodated.

As described above, according to the noise and vibration reduction pedestal according to the present invention, it is easy to reduce the noise and vibration by the reduction member inserted into the main body accommodating part, that is, rubber, silicone, or liquid, thereby preventing damage between occupants due to interlayer noise. With the cover, the reduction member is protected for a long time, and the manufacturing time and installation are simple and the working time is shortened.

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

Noise and vibration reduction pedestal according to the present invention, as shown in Figure 2 the main body 10 having a receiving portion 11 recessed in the upper side, the reducing member 20 is inserted into the receiving portion 11, the reduction The cover 30 is located above the member 20.

Specifically, the main body has an accommodating part 11 formed in the upper center, and an outer circumference of the accommodating part 11 is formed with a protruding part 12 protruding upward, so that a fixed leg such as furniture or home appliances is out of the pedestal. Do not.

At this time, the lower inside of the main body 10 is formed in a hollow shape, the main body is preferably formed of a high-strength material such as engineering plastic to have durability when a high load is applied.

In addition, the outer surface of the protrusion 12 is formed with a support portion 13 in contact with the bottom, the central support portion 14 is formed in the lower center of the main body 10 so that the main body is placed stably.

Here, the support 13 is formed to protrude from the outer surface of the protrusion 12, is formed so that its height is lowered toward the outside so that it can be stably placed on the floor.

Meanwhile, the reducing member 20 is inserted into the accommodating part 11, and the reducing member 20 is made of a material such as soft rubber having high elasticity, high sound insulation and sound absorption, high shock absorption effect, and low hardness silicone. In the case of a low hardness silicone, the silicone is inserted into a plastic bag.

In addition, a groove into which the fixing protrusion 31 to be described later is inserted is formed in the upper center of the reduction member 20.

Here, the reducing member 20 may be used to accommodate a liquid in a plastic bag, the liquid may be used industrial oil such as water or silicone oil, but is not limited thereto.

In addition, the reducing member 20 is formed to be spaced apart from the inner circumferential surface of the accommodating part 11 to have a space, and when the load is applied, the reducing member 20 is pressed to contact the inner circumferential surface of the accommodating part 11. .

The lid 30 located above the reduction member 20 prevents the reduction member 20 from being separated from the accommodation portion 11 and protects the reduction member 20 from being damaged.

In addition, the lower side of the cover 30 is formed with a fixing projection 31 to fit the groove of the reducing member 20 so that the cover 30 does not deviate from the initial position. As a result, the reduction member 20 is not damaged even after long-term use.

In addition, the diameter of the lid 30 is smaller than the diameter of the reduction member 20 so that the lid 30 does not touch the inner circumferential surface of the receiving portion 11.

In addition, the lower surface of the cover 30 is formed in a flat surface so as to be in contact with the reduction member, and the upper surface is formed in a flat surface so that a fixed leg such as furniture or appliances. In this case, as shown in FIG. 2B, the cover 30 ′ may be concave so as to have a gentle curve with a predetermined thickness so that the fixing legs of furniture or home appliances can be more stably placed.

And, since the fixing leg is in direct contact with the cover 30, it is preferable to manufacture using a high-strength material such as the body (10).
