Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention absorbs a vibration sound generated from a vibration generating device such as a bathtub equipped with a bubble generating device, a general device, etc., and at the same time, prevents the installation level of the device from changing. Absorption method relates to absorption leg seats.

[0002]

2. Description of the Related Art Recently, bathtubs having a bubble generating device or the like have become widespread. This bathtub can
Alternatively, even in a hotel, a drainage floor divided into concrete is formed on the floor base, and the legs of the bathtub are directly installed on the floor.

[0003]

However, since an impact sound is generated in the bathtub due to the bubble generation operation, this impact sound propagates directly from the floor base to the downstairs and the surroundings,
There is a noise problem. The same can be said for general appliances that generate vibration installed in general homes, buildings such as condominiums and offices, and factories. The present invention provides a method for absorbing vibration noise of a device, which absorbs vibration such as impact sound, contributes to solving a noise problem caused by propagation of the vibration, and at the same time prevents installation level of the device from changing. The purpose is to provide a vibration sound absorbing leg seat for the equipment.

[0004]

In order to solve the above problems, the vibration sound absorbing method of the present invention provides an appropriate hardness between the plate connected to the installation surface side and the plate arranged on the vibration generating device side. Install the vibration generator by inserting an elastic body such as rubber or synthetic rubber, and tightening this elastic body with a pressure close to or higher than the maximum load assumed for use on the vibration generator side. This is characterized by absorbing the vibration sound of the device.

Further, the vibration sound absorbing leg seat of the present invention includes a plate connected to the installation surface side, a plate arranged on the vibration generating device side, and a rubber having a proper hardness interposed between the plates or a synthetic material. It has at least an elastic body such as rubber, and this elastic body absorbs the vibration noise of the equipment by tightening it with the plate with a pressure close to or higher than the maximum load assumed for use on the side of the vibration generating equipment. The present invention is characterized in that it has a configuration adapted to do so.

The plate connected to the installation surface side may be a plate fixed to the installation surface side and connected to a projecting bolt so as to be adjustable in level.

Further, the vibration sound absorbing leg seat of the present invention is
A plate that is fixed to the installation surface and connected to a protruding bolt so that the level can be adjusted, a plate that is arranged on the side of the vibration generator, and a rubber or synthetic rubber that is interposed between both plates and has an appropriate hardness. An elastic body, an elastic body such as a rubber or synthetic rubber having a higher degree than the elastic body arranged outside the at least one plate, and both plates, an elastic body between them, and an elastic body on the outside. At least a bolt and nut for fastening and fixing them are provided, and the vibration noise of the device is generated by applying a pressure close to or higher than the maximum load assumed for use on the vibration generating device side for tightening with the bolt nut. It can be configured to absorb.

[0008]

Since the elastic body is compressed by tightening, it absorbs vibrations without causing level fluctuation of the equipment against load, and cuts off or attenuates sound propagation to the installation surface side.
Further, by connecting the plate on the installation surface side so that the level can be freely adjusted, the level can be conveniently adjusted during construction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic plan view of a bathtub showing an example in which the present invention is applied as a leg seat of a bathtub, and FIG. 2 is a sectional view of an essential part showing the leg seat of the bathtub.

A bathtub 1 is provided with a leg seat mounting portion 2 into which a bolt head can be housed by inserting a bolt into an appropriate portion of an outer shell 1a thereof.

Reference numeral 3 denotes a leg seat, which is fixed and erected by an appropriate means such as burying a base portion on an installation surface 4 such as a concrete floor, and a bolt of an appropriate length in which a whole or at least an upper portion is a male screw. 5 and the nut 4 from above and below at appropriate height positions of the bolt 4 by passing the bolt 4 through the four corners.
6, a plate 7 fixed by fastening, an elastic body 8 such as rubber or synthetic rubber having a proper hardness and a proper thickness placed on the upper side of the central portion of the plate, and the upper side of the elastic body 8 is superposed. A plate 9, an elastic body 10 such as rubber or synthetic rubber having a hardness higher than that of the elastic body 8 interposed below the plate 7, and a bathtub mounting portion 2 placed above the central portion of the plate 9. From the inside of the plate 9, the elastic body 8,
The plate 7 and the elastic body 10 are sequentially penetrated, and the elastic body 10
On the lower side, a tightening bolt 11 is formed by tightening and fixing them together by a nut 12 via a washer.

The elastic bodies 8 and 10 are made of a material capable of absorbing vibration and sound, and can support a load in an appropriately compressed state. As an example of a bathtub, they are sandwiched between the plates. The elastic body 8 made of synthetic rubber is the maximum load of the entire bath (having a bubble generating device to fill water,
The load when a predetermined number of people are on and the device is operating) is 50
Assuming 0 kg, load on one leg seat 1 is 125 k
Assuming g, the Shore hardness is preferably about 40 to 50, the thickness may be about 10 to 15 mm, and the area is preferably set within the plates 7 and 9 and wider than the end surface of the mounting portion 2 of the bathtub. Further, the Shore hardness of the elastic body 10 made of the other synthetic rubber is preferably about 60 to 85.

The plate 9 on the side of the bath is for uniformly distributing the tightening force of the bolts and nuts 11 and 12 over the entire elastic body 8. In FIG. 2, through holes are formed at the four corners of the plate 9, and the holes near the tip of the bolt 5 on the installation surface side are loosely penetrated through the holes to prevent the plate 9 from shifting. It is convenient for construction work. FIG. 3 shows an example of a structure in which the plate 9 does not have the above-described through hole structure and is separated from the bolt 5, but any structure may be used. The configuration of each part other than the above-described separation structure of FIG.

In the case of the tightening structure of the bolts and nuts 11 and 12, the elastic body is used to block the propagation of sound between the side of the bathtub 1 as the vibration generating device and the bolt 5 and the plate 7 connected to the installation surface 4. 8 and 10 have a vibration sound absorbing function.

Further, since the elastic body 8 is tightened by the plates 7 and 9 by the maximum assumed load on the bath 1 side, the elastic body 8 is influenced by the usage state (load state) of the bath.
Does not expand and contract, and it is possible to maintain the bathtub installation level at all times without fluctuation. If the installation level of the bathtub is easily displaced, cracks or gaps will be created in the joints and other parts of the wall or floor that are connected.

FIG. 4 shows another embodiment of the present invention different from the above. This leg seat 3A has a structure in which the rising upper end portion of the angle plate 9A is fixed to the lower end portion of the side surface of the bathtub or the side surface portion of the mounting portion 1a of the bathtub.
The horizontal portion of A is joined to the elastic body 8A, and the horizontal plate portion 7A formed on the fixing member 5A fixed to the installation surface side is joined to the other surface of the elastic body 8A. While sandwiching the elastic body 8A by
An elastic body 10A having a higher hardness is joined on the plate 9A, a bolt 11A is penetrated through the plate 7A, the elastic body 8A, the plate 9A and the elastic body 10A from the lower side of the plate 7A, and a nut 12A is screwed to the upper end portion. These are integrally tightened.

The fixing member 5A may have any structure, and may have a structure capable of adjusting the level. Further, each of the plates 7A and 9A may be on the same plane as the horizontal plane of the fixing member 5A or the horizontal plane of the angled plate, or may be a stack of different plates. The symbol M in FIG. 1 schematically represents the motor of the bubble generating device.

[0018]

As described above, according to the present invention, a bathtub or other vibration generating device can be installed on the installation surface via an elastic body capable of absorbing (damping) vibration noise such as impact noise of the device. It is possible to provide a vibration sound absorbing method for a device in which it is difficult to propagate the vibration sound to the installation surface side and a leg seat structure for installing the device.

At the same time, since the elastic body is tightened and installed at a pressure corresponding to the assumed maximum load, it is possible to absorb vibration noise and maintain the installation level of the vibration generating device at a constant level. While maintaining, it is possible to prevent the influence on the installation level fluctuation of the device due to the change of the usage mode, and to prevent the troubles such as cracks, gaps and separation from the installation environment.

If the fixing of the leg seat to the installation surface side is carried out as a structure in which the level can be adjusted freely, the level adjustment becomes easy, and the installation work and maintenance work of the equipment become extremely convenient and accurate.
