[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a rear perspective view of the vibration damping member according to the embodiment of the present invention, and FIG. 2 is a front perspective view of the vibration damping member with the release sheet removed. 3 is a sectional view taken along line III-III in FIG. 1, FIG. 4 is a perspective view showing a use state of the vibration damping member, and FIG.
FIG. 5 is a sectional view taken along line VV of FIG.

The vibration damping member includes a plate-shaped main body 1, a weak adhesive sheet 3 and a release sheet 4 as a weak adhesive layer arranged on one surface (front) 11 of the main body 1. And a covering sheet 2 as a covering layer arranged on the other surface (back surface) 12.

The plate-shaped main body 1 is made of a self-adhesive and flexible material such as unvulcanized rubber represented by butyl rubber as a main material, and is formed in a plate shape. It is attached by being wound around a controlled object such as. As the material, a material used for this kind of vibration damping member, such as a material obtained by mixing a material having a high specific gravity, such as iron, with a main material such as rubber or synthetic resin having self-adhesiveness can be used. Here, the flexibility means a degree of flexibility that can be deformed by a human hand according to the shape of a vibration-suppressed object such as a refrigerant pipe p.

The main body 1 can be implemented in various sizes and shapes according to the size of the object to be damped which is attached by winding or the like. In this example, one surface (front) 11
Is used by being wound around the outer surface of the pipe p.
1a, and a non-contact portion 11b in which the wound main bodies 1 contact each other and do not contact the outer surface of the pipe p. In this example, the non-contact portions 11b are provided on both sides of the contact portion 11a.

Next, the covering sheet 2 is arranged on the other surface (back surface) 12 of the main body 1. This is arranged to prevent the back surface 12 of the main body 1 from coming into contact with another object and sticking to the other object. are doing. As the covering sheet 2, it is appropriate to use a film made of a synthetic resin, but other materials or composite materials such as cloth, paper, and metal can also be used. The coating sheet 2 does not need to be peeled off from the main body 1 and thus does not need releasability, but can have releasability. In addition, this covering sheet 2
May cover the upper surface, the lower surface, and the left and right side surfaces in addition to the back surface 12.

Next, a weakly adhesive sheet 3 and a release sheet 4 are arranged on one surface (front) 11 of the main body 1. Coordinated only to 11a. This weakly adhesive sheet 3 has a contact portion 11a
To prevent the main body 1 from sticking to the pipe p. Therefore, the weakly-adhesive sheet 3 only needs to have a weakly-adhesive property at least on the outer surface side (they have no tackiness or have a weaker tackiness than the self-adhesiveness of the main body 1). 2 can be used, and in addition to a synthetic resin film, a cloth,
Other materials and composite materials, such as paper and metal such as aluminum foil, can also be used. Although this weakly adhesive sheet 3 adheres to the main body 1 by the self-adhesiveness of the main body 1, even if the inner surface side of the weakly adhesive sheet 3 is made to have adhesiveness and is attached by the adhesiveness of both. Good. The covering sheet 2 and the low-adhesive sheet 3 have a degree of flexibility such that they can be deformed by a human hand according to the shape of a vibration-suppressed object such as a refrigerant pipe p, similarly to the main body 1. Is used.

The releasable sheet 4 is provided on the non-contact portion 1 of the front surface 11.
1b. In this example, the non-contact portions 11 on both sides
In addition to b and 11b, the sheet is covered with a single release sheet 4 including the outer surface of the weakly adhesive sheet 3 on the contact portion 11a, but covers only the non-contact portion 11b. It may be. However, in terms of workability, one release sheet 4
It is more advantageous to cover the entire front surface 11 with. The releasable sheet 4 has a material having a high releasability such as silicon arranged on the inner surface side and is lightly adhered by the adhesiveness of the main body 1, but the releasable enough to be peeled off by a human hand. It has the nature. As described below, since the release sheet 4 is used after being peeled off, the non-contact portion 11b having self-adhesiveness of the main body 1 is exposed during use. Therefore, the non-contact portion 11b is the adhesive portion 11b according to the first aspect of the present invention.
Will be constituted. Further, the weakly adhesive sheet 3 constitutes the weakly adhesive portion 3 in the first aspect of the present invention.
Although not shown, the releasable sheet 4 is provided with a portion protruding from the main body 1 in, for example, the width direction (vertical direction in FIG. 1) or the like as a peeling allowance. You may make it easy to peel off than one. Further, as for the weak adhesive sheet 3, similarly to the release sheet 4,
A portion that protrudes from the main body 1 may be provided. The protruding portion of the weakly adhesive sheet 3 has no particular advantage when it is attached to a controlled object such as a pipe p.
This part can be used as a peeling allowance when the pipe is removed from the vibration-controlled object such as the pipe p.

In use, as shown in FIG. 2, the release sheet 4 is peeled from the main body 1 to expose the weakly adhesive sheet 3 and the non-contact portions 11b, 11b of the front surface 11. Then, as shown in FIG. 4 and FIG.
1b is applied to a controlled object such as a pipe p, and the whole is deformed and wound, and the non-contact portions 11b, 11b on both sides of the front surface 11 are joined together to adhere the non-contact portions 11b, 11b on both sides together. By fixing. As a result, the contact portion 11a of the main body 1 comes into contact with the damped object such as the refrigerant pipe p via the weakly adhesive sheet 3, and therefore does not adhere to the damped object. Ideally, the length of the weakly-adhesive sheet 3 and the outer periphery of the object to be damped, such as the refrigerant pipe p, should be the same, but even if the length is slightly longer or shorter,
There will be no significant impact on implementation. However, it is desirable from the viewpoint of preventing adhesion that the length of the weakly adhesive sheet 3 is equal to or longer than the outer peripheral length of the object to be damped such as the refrigerant pipe p. The non-contact portions 11b, 11b on both sides of the front surface 11 are adhered to each other, so that the vibration damping member is fixed without adhering to the damped object such as the pipe p. In order to prevent this more reliably, other fixing means such as binding with a wire or the like are not prevented.

Finally, when separating for recycling or the like, the non-contact portions 11b, 1
If 1b is cut from the root with a cutter or the like, it can be easily removed from the damped object such as the refrigerant pipe p, and the efficiency of the sorting operation can be increased. More specifically, if the weakly adhesive sheet 3 has no tackiness,
The main body 1 can be removed from the controlled object without any resistance. When the weak adhesive sheet 3 has an adhesive strength lower than the self-adhesive strength of the main body 1 (the contact portion 11a), the weak adhesive sheet 3 has a stronger self-adhesive strength.
(Abutment portion 11a) and peeled off from the object to be damped. In particular, in the case of a rubber damping material used today such as butyl rubber, it has a strong self-adhesive property and a rubber-specific tenacity, so it was difficult to peel off the material from the damped object. The low-adhesion sheet 3 has low self-adhesion and is a series of sheets, so that it can be easily removed as compared with the conventional example.

Next, another embodiment will be described with reference to FIG. In the above embodiment, the non-contact portions 11b are provided on both sides of the contact portions 11a, but in this example,
The non-contact portion 11b is provided on one side of the contact portion 11a, and the weak adhesive sheet 3 is arranged on the outer surface of the contact portion 11a as described above. Although not shown, the release sheet is positioned so as to cover only the outer surface of the non-contact portion 11b or the outer surfaces of the contact portion 11a and the non-contact portion 11b.

Before use, remove the release sheet,
As shown in FIG. 6 (A), the weakly adhesive sheet 3 on the contact portion 11a is wound around the outer periphery of the damped object such as the pipe p, and the self-adhesive portion of the main body is exposed. The non-contact portion 11b is placed on the cover sheet 2 on the back surface 12 side of the main body 1 and is fixed by its adhesiveness. That is, in this example, each of the end portion of the contact portion 11a and the non-contact portion 11b is fixed by sticking to the covering sheet 2. Alternatively, FIG.
As shown in (B), the weakly adhesive sheet 3 on the contact portion 11a is wound around the outer periphery of a vibration-controlled object such as the pipe p and the end of the contact portion 11a is covered with the pipe p or the like. The protruding abutting portion 11 is made to protrude from the damping material.
The end of “a” is fixed by matching with the non-contact portion 11b. That is, in this example, each of the end portion of the contact portion 11a and the non-contact portion 11b is fixed by being adhered to the weak adhesive sheet 3.

In the above embodiment, the main body 1 having self-adhesiveness is used. However, the present invention can be implemented using the main body 1 which has flexibility but does not have self-adhesiveness. In this case, the non-contact portion 11b is provided with an adhesive by coordinating the pressure-sensitive adhesive, and the contact portion 11a is left in a non-adhesive state without the adhesive. Then, the release sheet 4 may be arranged on the non-contact portion 11b on which the adhesive is arranged.

Further, in the above-described embodiment, an example in which one damping member is used has been shown. However, as shown in FIG. 7, one or more damping members are provided between the two damping members. A damped object such as the pipe p can also be attached so as to sandwich it. In the example of FIG. 7, an object to be damped such as two pipes p is sandwiched between a pair of damping members, and the weak adhesive sheets 3 are attached to both ends of each damping member. Is coordinated body 1
In addition to arranging the non-contact portions 11b, 11b, the non-contact portion 11c to which the weak adhesive sheet 3 is arranged is also arranged at the center. In other words, the contact portions 11a, 11a which are not covered with the weak adhesive sheet 3 are provided at positions where the two contact portions 11a, 11a, 11a come into contact with the object to be damped, such as the two pipes p.
a, a non-contact portion 11c is provided between
11b is coordinated. Then, the two vibration damping members are arranged to face each other, and the contact portion 11a is connected to each pipe p.
The non-contact portions 11b, 11b and the central non-contact portion 11c are adhered to the other non-contact portions 11b, 11b and the central non-contact portion 11c. It is to be noted that the covering sheet 2 is arranged on the back side of the main body 1 as in the previous example. Although not shown, a release sheet 4 similar to that shown in the previous example is disposed on the contact portion 11a.
Except as shown in this example, the non-contact portions 11b, 11b at both ends
It can be easily understood from the example of FIG. 6 that it can be implemented by being provided at one of the left and right ends. Further, the present invention can be implemented without providing the central non-contact portion 11c. Further, the same usage method can be adopted for one or three or more pipes p and the like to be damped. In each embodiment, the weak adhesive sheet 3 and the release sheet 4 are arranged on one surface (front) 11, and the coating sheet 2 is arranged on the other surface (back) 12 of the main body 1. However, the weak adhesive sheet 3 and the release sheet 4 are arranged on both sides 12 and 11 of the main body, and the release sheet 4 on one side is peeled off and attached to the vibration-controlled member in use. It can also be implemented. The weakly-adhesive sheet 3 and the release sheet 4 are not limited to sheet-like ones, and may be made of a non-adhesive layer or a layer made of an adhesion-inhibiting material having a lower adhesiveness than the adhesive portion 11b. Anything can be used as long as As the tackiness inhibiting material other than the sheet, a means for applying a resin such as an acrylic emulsion can be exemplified.

[0018]

As described above, in the vibration damping member according to the first invention of the present application, the weak adhesive portion 3 is brought into contact with the non-vibration damping material, and the adhesive portion 11b is adhered to another portion of the vibration damping member itself. In this way, the damping member is attached to the vibration-suppressed object p, so that the attaching operation is simple, and at the same time, the non-vibration-suppressing object is in contact with the non-adhesive or the adhesive portion 1.
Since it is the weak adhesive portion 3 having adhesiveness weaker than 1b,
It can be easily removed and separated and discarded or collected. The vibration damping member according to the second invention of the present application is a contact portion 11a in which at least one surface of the main body 1 having flexibility and self-adhesive force abuts against a vibration damped object p such as a refrigerant pipe.
And a non-contact portion 11b that does not contact the contact portion 1b.
1a has no adhesiveness or is covered with a weakly adhesive sheet 3 that is weaker than the self-adhesive force of the main body 1;
b is covered with a release sheet 4 having releasability from the main body 1 having a self-adhesive force. Therefore, at the time of attachment, the weakly adhesive sheet 3 covering the contact portion 11a of the main body 1 is left as it is, so that the contact portion 11a having self-adhesion comes into direct contact with the damped object p. In a state without any occurrence, the object is moved along the controlled object p. On the other hand, the non-contact portion 11b of the main body 1 is exposed by peeling the release sheet 4, and the self-adhesive force of the exposed non-contact portion 11b allows the non-contact portion to adhere to another portion of the vibration damping member itself. , Fixing is completed. Therefore, the controlled object p
Is not in contact with the main body 1 having a self-adhesive force, so that when separating, simply cut off the non-contact portion 11b with a carter or the like to easily separate the vibration damping member and the vibration damped object. Can be done. The third invention of the present application is the second invention.
In addition to the effects of the invention, the main body 1 has a plate-like shape, so that it is suitable for being wound around a tubular vibration-suppressed object such as a pipe, and is further separated on both sides or one side of the contact portion 11a. Since the non-contact portion 11b covered by the mold sheet 4 is arranged, the non-contact portions 11b, 11b at both ends face each other and are adhered to each other, or one of the contacted portions 11a. Is superimposed on the other end side of the main body 1, which has an effect that it can be easily attached to the vibration-controlled object. According to the fourth invention of the present application, since one release sheet 4 is arranged on the non-contact portions 11 b on both sides and on the weak adhesive sheet 3, one release sheet 4
The method of using the vibration damping member according to the third aspect of the invention described above can be employed simply by peeling off, and an extremely simple mounting operation can be realized. In addition, since the other surface is covered with the covering sheet 2, even if the other surface comes into contact with another object, there is no sticking.
