The elasticity of this material provides a vibration damping effect. This vibration-damping pad is known from Japanese Utility Model Publication No. 38-5613 in which a large number of protrusions are provided on the front surface or both front and back surfaces of the base in order to enhance the vibration-damping effect.
Further, a structure in which a plurality of types of projections having different heights are combined in this group of projections is also known from Japanese Utility Model Publication No. 57-44126. If the projections with different heights are combined, the elastic projections are sequentially elastically deformed as the load (vibration) increases, and the vibration absorbing action is gradually performed.

Since it is transmitted in the central portion, the elastic deformation of the protrusion is one pattern in the vertical direction, and the deformation amount (deflection amount) is small. Further, even with respect to the vibration in the oblique direction and the horizontal direction, the vibration acts on the central portion of the lower protrusion, so that the deflection amount of the lower protrusion becomes small. In this respect, the conventional pad still has an insufficient vibration absorbing (vibration damping) effect.

される場合を示している。This anti-vibration pad is used by being laid on the lower surface of various machines that generate vibration in a state where it is cut (or not cut) into an appropriate size as described above. FIG. 3 shows a case where one pad is laid between the lower surface of the machine M and the floor surface F.

なるため、振動吸収効率が良いものとなる。In this state, the vibration from the machine M is basically absorbed by the elastic deformation action of the entire pad by the elastic material, and the vibration absorption action by the elastic deformation (deflection) of the projection groups on the front and back sides is added thereto. In this case, since each of the protrusion groups G 1 and G 2 in the protrusion groups on both the front and back sides is composed of four types of protrusions 2 to 5 having different heights, it is the highest in the no-load or small-load (small vibration) state. The first protrusion 2 comes into contact with the lower surface of the machine M or the floor surface W, and the vibration absorbing function is exhibited by the deflection of the first protrusion 2. Then, as the load increases, the second protrusion 3, then the third protrusion 4, and then the fourth protrusion 5 are sequentially brought into contact with the lower surface of the machine M or the floor surface F, and finally all the protrusions 2 to 5 are reached. The vibration absorption function is exhibited by the deflection of the. That is, the vibration absorbing action is gradually achieved by the stepwise contact of the projections 2 to 5 with the lower surface of the machine M or the floor surface F. Moreover, the highest first
The protrusion 2 has the smallest size and is most easily bent, and is less likely to be bent in a stepwise manner. Since the bending characteristics of the protrusion groups G 1 and G 2 correspond to an increase in load, the vibration absorption efficiency is improved. It will be good.
このような突起２〜５による振動吸収機能は、第４図に
示すように二枚（または三枚以上）のパッドが上下積層
状態で使用される場合にも、基本的に同様に果される。The vibration absorbing function of the protrusions 2 to 5 is basically the same when two (or three or more) pads are used in a vertically stacked state as shown in FIG. .
また、このパッドによるときは、表裏の突起グループに

る。Also, when using this pad, the positional relationship of the protrusions is set so that the different types of protrusions in the front and back protrusion groups correspond to each other with their centers displaced in the circumferential direction. An effective vibration absorbing function is exhibited both when using a single sheet and when using a pad stack.

たわみ量が大きくなる。このため、振動吸収機能が拡大
される。That is, in the state where one pad shown in FIG. 3 is used,
Vertical vibrations acting on the front side protrusions 2 to 5 are applied to the back side protrusions 2 to 5 through the base 1. In this case, the front side projection 2
5 is in contact with the machine M, and the back side projections 2-5 are in contact with the floor surface F, respectively, from the front side first projection 2 to the back side fourth projection 5, the front side second projection 3 to the back side third projection 4, and the front side. Vibrations are transmitted from the fourth protrusions 5 to the back-side first protrusions 2, respectively. At this time, this vibration acts as an eccentric load on each of the back-side protrusions 2 to 5 at a position deviated from the center thereof in the circumferential direction. Therefore, each of the back side protrusions 2 to 5 largely bends in the portion that receives the unbalanced load. In other words, each back protrusion 2
5 is not compressed and deformed as a whole so that the total height becomes low as in the case where a load is applied to the center,
Since an irregular and vigorous elastic deformation movement is performed in which it is partially crushed by an eccentric load and other parts are also deformed by its reaction, the amount of deflection of the entire projection, and thus of the entire projection group, increases. Therefore, the vibration absorbing function is expanded.

効果的な振動吸収機能が発揮される。Such an operation is similarly performed in the pad stacking use state shown in FIG. 4 and between the protrusion groups of the upper and lower pads facing each other. That is, the vibration transmitted from the back side projections 2 to 5 of the upper pad to the front side projections 2 to 5 of the lower pad acts as an eccentric load on the front side projections 2 to 5 at a position deviated from the center thereof, and the opposite Since the force acts on the backside protrusions 2 to 5 of the upper pad, the respective protrusions 2 to 5 facing each other are largely deflected, thereby exerting an effective vibration absorbing function.

吸収効果が高められる。Further, even when diagonal or horizontal vibration is applied, for example, the back side fourth protrusion 5 of the upper pad comes into contact with the front side first protrusion 2 of the lower pad at a position deviated from the center in the pad stacking use state. Since the diagonal or horizontal vibration (load) acts eccentrically on the upper back side fourth protrusion 5, the protrusion 5 is easily deflected in the horizontal direction, thereby absorbing the vibration. The effect is enhanced.

果が高いものとなる。In addition, according to the pad of this embodiment, each protrusion 2-5
Are formed in a fan shape and are arranged at intervals on the same circumference, the horizontal force is applied to each of the fan-shaped projections 2 to 2.
It will be accepted on the irregular side according to 5. Therefore, compared with a simple circular protrusion or the like, the effect of absorbing and damping vibration is high.
以上のような点により、この防振パッドによるときは、
垂直、斜め、水平の各方向の振動を効率良く吸収し、高
い防振効果を得ることができる。Due to the above points, when using this anti-vibration pad,
It is possible to efficiently absorb the vibration in each of the vertical, oblique, and horizontal directions, and obtain a high vibration damping effect.

を挿入するといった面倒がなくなる。On the other hand, when the pad stack shown in FIG. 4 is used, the protrusions of different types (different heights) are brought into contact with each other between the protrusion groups of the upper and lower pads which face each other under no load, and all the protrusion surfaces come into contact with each other. As a result, the stability of the pad laminated state is improved. Therefore, when the pads are stacked, the trouble of inserting an iron plate or the like between the pads to fill the gap between the protrusions is eliminated.

となる。(Effects of the Invention) As described above, according to the present invention, a plurality of types of protrusions having different heights and cross-sectional areas form protrusion groups on both the front and back sides, and the protrusion groups on the both sides have different types. Set the positional relationship of the protrusions so that they correspond to each other when the centers of the protrusions are displaced from each other in the circumferential direction, and the vibrations in the vertical, diagonal, and horizontal directions are in contact with the floor surface or the pad or pad. Since it is configured to act as an eccentric load at a position deviated from the center of the protrusions for the facing facing protrusions in the laminated use state, the protrusions of the protrusions are The deflection becomes active due to the unbalanced load. As a result, the vibration absorbing function of the protrusions is expanded, and the vibration damping effect is enhanced.
