However, in the sliding anti-vibration support device, the rolling anti-vibration support device, and the like, the restoring force returned to the initial position is not generated, and after the vibration, it is necessary to return to the initial position by manually pushing the daily utensils, the bookshelf, and the like.

As a shock-proof support device having a restoring function for restoring force, for example, a pendulum-type anti-vibration device described in Patent Documents 1 and 2 has been proposed. However, in the anti-vibration device of the above-mentioned proposals, scrolling is basically used, so that although shockproof The property is superior, but it is difficult to obtain an attenuation function that preferably attenuates the vibration.

On the other hand, Patent Document 3 proposes a pendulum-type anti-vibration device which uses a steel bar damper in addition to the restoration function in order to obtain an attenuation function, but in the anti-vibration device, in order to use a steel bar The damper needs to fix one end of the steel rod damper, whereby the installation work becomes large-scale, and as the displacement increases, the absorption effect of the seismic energy is reduced, and it is difficult to obtain an effective attenuation function.

The present invention has been made in view of the above points, and an object thereof is to provide an anti-vibration support device which can obtain an effective attenuation function in addition to a restoration function, and can easily perform anti-vibration support such as a daily display such as a display stand and a bookshelf.

The function of the shock-proof support object can be easily prevented by providing the concave-arc concave lower surface of the anti-vibration support object, and since the rotation period of the free-rotation member, that is, the swing period depends on the eccentric amount, Therefore, the long period of vibration can be easily achieved only by appropriately setting the amount of eccentricity.

The semi-spherical convex surface 32a has a cross-sectional arc-shaped lower surface 33; a cross-sectional arc-shaped lower surface 33 including a portion of the spherical surface and having a center of curvature O2 and a surface 10 of the floor 9 are rolled freely in the direction R Contacting, and having the same radius of curvature r2 as the radius of curvature r1 of the concave lower surface 4 of the cross-sectional arc, and having a friction coefficient μ2 with respect to the surface 10 of the floor 9 being larger than the convex upper surface 23 of the cross-sectional arc The arcuate concave lower surface 4 is formed in such a manner that the friction coefficient μ1 (μ2>μ1).

The through hole 54; the lower portion 11 is passed through the circular hole 54 so as to be in contact with the surface 10 of the floor panel 9 in the direction R by the cross-sectional arc-shaped lower surface 33; the anti-disengagement mechanism 13 is interposed between the free-rotating member 12 In the rotation of the load receiving member 7 with respect to the direction R of the everyday tool 2, as shown in FIG. 4, the collision of the inner peripheral end 56 of the flange portion 55 with the circular arc-shaped lower surface 33 is prohibited. The freely rotating member 12 is rotated by a certain amount or more in the direction R.

In order to prevent the daily appliance 2 from being inclined with respect to the horizontal direction H, that is, in order to extend the lower surface 3 in the horizontal direction H, a plurality of at least three shock-proof supporting devices 1 are disposed on the lower surface 3 of the outer casing 2 of the daily appliance 2, Each of the anti-vibration support devices 1 is in a stationary state as shown in FIG. 1 when the vibration in the horizontal direction H caused by the earthquake is not applied to the floor panel 9 and is concave in the cross-sectional arc convex upper surface 23 The entire surface of the lower surface 4 is in contact with each other. On the other hand, the freely rotating member 12, which is in contact with the surface 10 of the floor 9 at the apex 42 of the circular arc-shaped lower surface 33, shares the load on the floor 9 to support the everyday appliance 2. In order to prevent the daily appliance 2 from being tilted to maintain the level; when a vibration in one direction in the horizontal direction H caused by the earthquake is applied to the floor 9, one of the directions R is generated in the freely rotating member 12 of each of the anti-vibration support devices 1. The torque of the direction, and the free-rotating member 12 of each anti-vibration support device 1 is accompanied by the torque of the cross-section arc based on the difference (μ2>μ1) between the friction coefficient μ2 and the friction coefficient μ1 as shown in FIG. Convex upper surface 23 is slid in one direction in the direction R of the concave lower surface 4 of the cross-sectional arc, and is rotated on the surface 10 of the floor surface 9 in a direction in the direction R by the circular arc-shaped lower surface 33. In the rolling rotation, each of the anti-vibration support devices 1 prevents the vibration applied to the horizontal direction H of the floor panel 9 from being transmitted to the daily tool 2, and the shock-proof support of the daily appliance 2, and on the other hand, the eccentricity δ according to the center of curvature O1 and the center of curvature O2 The radius of curvature r1 of the arcuate convex upper surface 23 and the radius of curvature r2 of the convex lower surface 33 of the cross section are different, and the daily appliance 2 is lifted in the vertical direction V in rotation in one direction of the direction R. The free-rotating member 12 generates a restoring moment returning to a stationary state based on the eccentric amount δ at its respective rotational positions, by which the free-rotating member 12 is convexly curved on the surface 10 of the floor 9 Surface 33 Rotating in the opposite direction in the direction R, and then, the torque of the vibration in two directions based on the horizontal direction H caused by the earthquake and the restoring moment based on the eccentric amount δ, the so-called pendulum motion with a certain period is free. After the vibration of the floor member 9 in the horizontal direction H caused by the earthquake disappears, the sliding member 12 has a frictional friction coefficient μ1 of the concave lower surface 4 with respect to the circular arc convex lower surface 23, and is free. The rolling friction of the cross-sectional convex lower surface 33 of the rotating member 12 with respect to the surface 10 of the floor 9 causes the oscillation of the pendulum motion caused by the dissipation of the vibration energy to converge, and returns to the rotational position in the stationary state shown in FIG. Thereby, the daily appliance 2 is returned to the initial position before the vibration.

In the anti-vibration support device 1 provided above the floor panel 9 and the daily appliance 2 for shock-proof supporting the daily appliance 2 on the floor 9, the upper portion 8 has a cross-sectional arc-shaped upper surface 23, and the cross-sectional arc-shaped convex upper surface The entire surface of the 23-section and the concave arc-shaped lower surface 4 is slidably contacted in the direction R by the friction coefficient μ1, and has the same radius of curvature r1 as the radius of curvature r1 of the concave lower surface 4 of the cross-sectional arc; the lower portion 11 has a circular arc-shaped lower surface 33 having a curved convex lower surface 33 that is in rolling contact with the surface 10 of the floor panel 9 in the direction R and having the same radius of curvature r1 as the concave lower surface 4 of the cross-sectional arc. Curvature radius r2; in the static state, the center of curvature O1 of the convex upper surface 23 of the cross-sectional arc is opposite to the center of curvature O2 of the convex lower surface 33 of the cross-section of the arc in the vertical direction V with an eccentric amount δ toward the arc of the cross-section The lower surface 33 is eccentric, whereby, in addition to the pendulum type restoring function, it can also be produced by frictional sliding with a friction coefficient μ1 of the cross-sectional arcuate upper surface 23 with respect to the concave arc-shaped lower surface 4 of the cross-sectional arc. Frictional resistance is effective By reducing the function, and by providing the cross-sectional arc-shaped lower surface 4 of the daily tool 2 not only by the load receiving member 7, but also by directly using the surface 10 of the floor 9, the vibration of the daily appliance 2 can be easily performed, and only The long period of vibration can be easily achieved by appropriately setting the eccentric amount δ. Further, in this example, the concave lower surface 4 of the cross-sectional arc, the convex upper surface 23 of the cross-sectional arc, and the convex arc under the cross-section are formed. The surface 33 contains a part of the spherical surface, so that the earthquake can be used for all directions related to the horizontal direction H, that is, the vibration of the earthquake in all directions in the horizontal plane. 2.

According to the anti-vibration support device 1 having the detachment prevention mechanism 13, even if the free-rotation member 12 is intended to rotate substantially in the direction R due to the unexpected large horizontal direction H vibration, the rotation of the free-rotation member 12 can be prohibited from being rotated more than a certain amount. The free-rotation member 12 is prevented from being detached from the daily tool 2 by the load-receiving member 7, whereby the overturning of the daily appliance 2 and the like can be prevented, and the hazard caused by the earthquake can be minimized.

Further, in the anti-disengagement mechanism 13 having the surrounding body 51, in the stationary state of the anti-vibration support device 1, since the flange portion 55 is close to the surface 10 of the floor panel 9, the anti-vibration support device 1 can be surrounded by the stationary state. The inner portion 57 of the body 51 is semi-sealed with respect to the outer portion 58, and dust from the outer portion 58 can be prevented from entering the inner portion 57, thereby preventing malfunction of the anti-vibration support device 1 caused by dust, and in order to further exert the effect, it is also possible to prevent earthquakes. When the support device 1 is in a stationary state, after ensuring that the cross-sectional arcuate lower surface 33 or the flat surface 61 (refer to FIG. 5) is in contact with the surface 10 of the floor panel 9, the flange portion 55 is slightly in contact with the surface 10 of the floor panel 9. The surrounding body 51 is formed.

Further, in the anti-vibration support device 1 shown in Fig. 1, the lower portion 11 is formed by a semi-spherical spherical portion, but alternatively, as shown in Fig. 5, the spherical band portion defined by the ball band is formed; The lower portion 11 including the ball portion has a cross-sectional arcuate lower surface 33 having a spherical surface of the ball portion and having a radius of curvature r2 and a center of curvature O2, and further has a surface 10 of the floor 9 in a stationary state. a flat surface 61 having a small-diameter end surface 64 of the ball portion surrounded by the circular arc-shaped lower surface 33; the cross-sectional arc-shaped lower surface 33 and the flat surface 61 are integrally formed in the intermediate portion 21 Next, the exposed surface of the covering layer 34 of the rigid spherical strip-shaped lower body 32 including a rigid metal or a hard resin or the like is covered and covered; the covering layer 34 is provided with a spherical strip layer 63 which is covered and fixed to the lower body 32. a ball-shaped convex surface 62 of the ball portion; and a circular end surface layer 65 covering the small-diameter end surface 64 of the ball portion of the lower body 32; and a circular arc convex having a friction coefficient μ2 with respect to the surface 10 of the floor 9. The lower surface 33 is formed by the exposed surface of the strip layer 63. Sample 9 with respect to the surface of the floor 10 The flat surface 61 having the friction coefficient μ2 is formed by the exposed surface of the end face layer 65.

Each of the anti-vibration support devices 1 having the lower portion 11 shown in FIG. 5 and formed in the same manner as in FIG. 1 is in a stationary state as shown in FIG. 5 when the vibration in the horizontal direction H caused by the earthquake is not applied to the floor panel 9. And the circular arc convex upper surface 23 is contacted by the entire surface of the concave arc-shaped lower surface 4 with a friction coefficient μ1, and on the other hand, the entire surface of the flat surface 61 and the surface 10 of the floor 9 have a friction coefficient μ2. (μ2>μ1) the free-rotating member 12 that is in contact with the floor 9 shares the load of supporting the daily appliance 2 so that the daily appliance 2 is not tilted to keep it horizontal, and the free-rotating member 12 is not generated on the free-rotating member 12.
