2. Description of the Related Art Anti-vibration rubbers have been used for supporting vibration-absorbing floor boards of houses and gymnasiums. This vibration-proof rubber can be used easily because it is small and lightweight for its load capacity. However, as shown in FIG. 10, the spring characteristics of such a vibration-isolating rubber have linearity in which the displacement increases linearly with respect to the load, so that it is large even when supporting a floor plate or other members. It was accompanied by displacement. As described above, if the displacement of the floorboard becomes large, the livability deteriorates, and therefore, it was not satisfactory as a support member for the floorboard.

When a load is applied from the upper surface of such a vibration-proof rubber, the amount of flexure increases until the spherical body comes into contact with the floor base due to the groove provided between the upper surface and the lower surface. However, after the spherical body comes into contact with the floor base, the load is received together with the spherical body by the abutting portion of the lower surface other than the spherical body, so that the amount of bending is reduced. Therefore, the displacement is small for supporting a large load. When a load is further applied, the buckling displacement of the lower surface portion other than the spherical body increases, and the ratio of the load applied to the spherical body increases, so that the amount of bending increases.

As shown in FIG. 2, the anti-vibration rubber 1 constructed as described above is attached to the lower part of the support leg 100 and disposed on the floor base 101, and the upper part of the support leg 100 is
It is fixed to. In such a state, the floorboard 10
When an impact force is applied from 2, a load due to the impact force is applied to the upper surface 2 of the vibration-proof rubber 1 via the support leg 100. On this occasion,
As can be seen from the relationship between the load and the amount of deflection shown in FIG. 3, since the load is initially received by the ribs 5 together with the sphere 4, the amount of deflection is reduced. Therefore, the displacement is small for receiving a large load. When a load is further applied, the buckling displacement of the rib 5 increases, and the ratio of the load applied to the sphere 4 increases, so that the amount of bending increases. Therefore, the impact force from the floor plate 102 can be absorbed by the buckling displacement of the sphere 4. After that, since the contact area of the spherical body 4 increases, the amount of deflection decreases and the displacement decreases. That is, in the initial stage in which a load is applied to the impact force from the floor plate 102, the vibration isolating rubber 1 according to the embodiment of the present invention is in a region where buckling by the sphere 4 reinforced by the rib 5 is unlikely to occur, In the stage, there are three patterns of spring action, that is, a shock absorbing region due to the buckling of the sphere 4 and a region in which the buckling by the sphere 4 is unlikely to occur in the later stage, so that a non-linear spring characteristic can be provided. Thereby, an excellent vibration-proof effect against the impact force from the floor plate can be obtained.

The anti-vibration rubber 10 configured as described above is used in the same manner as the anti-vibration rubber 1 described above. That is, as shown in FIG. 5, it is attached to the lower part of the support leg 100 and disposed on the floor base 101, and the upper part of the support leg 100 is
It is fixed to. In such a state, the floorboard 10
When an impact force is applied from 2, a load due to the impact force is applied to the upper surface 11 of the vibration-proof rubber 10 via the support leg 100. At this time, as can be seen from the relationship between the load and the amount of deflection shown in FIG. 6, initially, the load is received by the rib 15 together with the hemisphere 13 on the upper surface portion 11, so that the amount of deflection is reduced. Therefore,
The displacement is small for receiving a large load. And
When a load is further applied, the buckling displacement of the rib 15 increases, and the ratio of the load applied to the hemisphere 13 increases, so that the bending amount increases. Therefore, the impact force from the floor plate 102 can be absorbed by the buckling displacement of the hemisphere 13.
After that, since the contact area of the hemisphere 13 increases, the amount of deflection decreases and the displacement decreases. That is, the anti-vibration rubber 1 according to another embodiment of the present invention.
0 is the rib 1 at the initial stage when a load is applied to the impact force from the floor plate 102, as in the case of the vibration isolating rubber 1 described above.
The three types of springs include a region hardly causing buckling due to the hemisphere 13 reinforced by 5, a shock absorbing region due to buckling of the hemisphere 13 in the middle stage, and a region hardly causing buckling due to the hemisphere 13 in the late stage. Since this is an action, a non-linear spring characteristic can be provided. Thereby, an excellent vibration-proof effect against the impact force from the floor plate can be obtained. By changing the thickness of the rib 15, the spring constant in the initial stage where a load is applied can be adjusted.

The anti-vibration rubber 20 configured as described above is used in the same manner as the two anti-vibration rubbers 1 and 10 described above.

Becomes large. However, the spherical body 24 is
After the contact with the spherical body 24, the load is applied together with the spherical body 24.
Since the contact portions of the lower surface portion 22 other than the above will be received,
The amount of deflection is reduced. Therefore, the displacement is small for supporting a large load. When a load is further applied, the buckling displacement of the lower surface portion 22 other than the spherical body 24 increases, and the ratio of the load applied to the spherical body 24 increases, so that the amount of bending increases. Therefore, the impact force from the floor plate 102 can be absorbed by the buckling displacement of the spherical body 24. After that, since the contact area of the spherical body 24 increases, the amount of deflection decreases and the displacement decreases. In other words, the vibration isolating rubber 20 according to another embodiment of the present invention has an initial stage in which a load is applied to an impact force from the floor plate 101 in a region buckled by the groove 25 in the front stage, and a spherical body. 24 is spherical body 2 after contact
4 is a region that is reinforced by the abutting portion of the lower surface portion 22 and is less likely to buckle, a shock absorbing region due to buckling by the spherical body 24 in the middle stage, and a spherical body 2 in the later stage.
Since there are four patterns of spring action in a region where buckling by 4 is unlikely to occur, it is possible to provide a non-linear spring characteristic. Thereby, an excellent vibration-proof effect against the impact force from the floor plate can be obtained.
