Description

The present invention relates to a shock absorber for supporting an article or structure that is affected or broken by vibration, or a device that generates vibration.

2. Description of the Related Art Conventionally, there are various types of shock absorbers such as vibration-proof rubber and springs as shock absorbers for vibrations caused by transportation or earthquakes, and vibration sources such as motors and engines.

In the shock absorber as described above, various measures can be taken according to the size of the article to be supported. However, in the shock absorber using these, there is a problem that the overall structure including the mounting portion is enlarged. . In addition, these have no function of absorbing vibration, and even a slight vibration may promote vibration, and it merely absorbs an impact. In particular, rubber or the like has a problem of deterioration depending on the installation location and environment, and has a disadvantage that it cannot withstand long-term use.

  Therefore, as a result of diligent research in view of the above problems, the present inventor has achieved the present invention. The feature of the present invention is that each of the diameter positions of the wire rope spirally wound around the support base is 2. One of the retainers of the plurality of shock absorbers formed by being sandwiched between the retainer constituting member members is attached.

  The “retainer constituting member” in the present specification is a member that supports a wire rope wound in a spiral shape, and is a member that is sandwiched from the inner peripheral side and the outer peripheral side along the longitudinal direction of the wire rope. Say. The retainer formed by the retainer constituent member is configured as a shock absorber by being provided at the diameter position of the wire rope. In this invention, it comprises as a buffering device by attaching one retainer of a some buffering tool to a support stand.

  For this reason, the retainer attached to the support base is provided with a fixing portion, and is fixed with a bolt, a nut, or the like. The other retainer may be provided with a mounting portion, and the retainer constituting member may be widened for easy installation, or the surface may be provided with unevenness to make it difficult to slip.

  The “support base” refers to a member that supports and places an article or the like as a buffer base with a plurality of shock absorbers attached thereto. Conversely, it can also be used as a support plate for a shock absorber that supports articles and the like, and in this case, the articles can be supported by sandwiching the articles and the like with the two support bases vertical. In the present invention, a plurality of retainer components may be formed on a part of the support base. That is, parts can be omitted by using the retainer constituting member that is arranged on the outer peripheral side of the wire rope.

The shock absorber referred to in the present invention is a structure that is supported by two opposing retainers provided at the diameter position of a spirally wound wire rope, in addition to vertical compression by a coiled wire rope, Vibration and shock can also be absorbed in the front-rear and left-right directions. For this reason, besides setting the support base to a flat plate shape, the setting of the buffer direction can be made arbitrary by providing an angle at the retainer mounting portion. Moreover, you may change an attachment angle by making the retainer structural member distribute | arranged to the outer peripheral side of a wire rope bend along a longitudinal direction. Furthermore, the shock absorber can be easily set by attaching the shock absorber to the support base in a rotatable manner.

  In the shock absorber according to the present invention, a plurality of shock absorbers each formed by sandwiching the diameter position of a spirally wound wire rope between two retainer constituent members are attached to a support base with one retainer. This makes it possible to easily and reliably protect articles and the like supported by the support base and the shock absorber from vibration and impact. In particular, this shock absorber is a completed structure as a shock absorber with one retainer arranged at the diameter position of the wire rope fixed to the support base and the other retainer as the installation member. There is no need to form a part, and there is an effect that it is compact and does not choose an installation place.

In addition to the spring action, the wire rope also has a damper effect due to friction between the wire rods accompanying the deformation of the wire rope, and can suppress unnecessary vibration. In addition, the wire rope wound in a coil shape has a very beneficial effect such that the buffering action varies depending on the installation direction and angle, so it can be easily handled according to the usage environment by setting the direction and angle. is there.

The shock absorber according to the present invention solves the above problems by adopting a structure in which a wire rope wound in a spiral shape is attached to a support base at the diameter position.

  FIG. 1A shows an embodiment of a shock absorber 1 according to the present invention, which is a pallet in which shock absorbers 3 are arranged as legs at four corners of a rectangular support base 2. The shock absorber 3 has a structure in which a retainer 5 is attached to a diameter position of a wire rope 4 wound spirally as shown in FIG. 2B, and one retainer 5 is fixed to the support base 2 with a bolt. Yes. The retainer 5 is composed of two retainer constituting members 51 sandwiched between the wire ropes 4. The shock absorbing action by the elasticity of the wire rope 4 exposed from the retainer 5 and the damper action by the friction between the wire members constituting the wire rope 4. Is obtained.

Since the shock absorber 3 is composed of the wire rope 4 wound spirally and the retainer 5 attached to the diameter position thereof, the shock absorber 3 has a buffering action not only in the vertical direction but also in the front-rear and left-right directions. With respect to the front-rear direction, which is the axial direction of the wire rope 4 wound spirally, the elasticity in the front-rear direction can be made uniform by winding the spiral inclination direction symmetrically as shown in FIG. Thereby, it can respond to the twist of the up-down direction and the left-right direction which is a radial direction. In addition to this, the shock absorbers 3 may be arranged radially, or two shock absorbers 3 whose winding directions are opposite to each other may be provided.
Moreover, as the retainer structural member 51 which comprises the retainer 5 of the buffer 3, it is good also as a structure which serves as the support stand 2 as shown in FIG. This is a structure in which a groove 22 into which the wire rope 4 is fitted is formed in the support base 2, and the support base 2 itself constitutes the retainer 5 of the shock absorber 3.

As a method of installing the shock absorber 3, as shown in FIG. 4A, a retainer mounting portion 21 that is inclined to the support base 2 is provided, and the shock absorber 3 is tilted along the axis of the wire rope 4, thereby In addition, an elastic action in the radial direction can be obtained. As a method of tilting the shock absorber 3 along the axis of the wire rope 4, the retainer constituting member 51 is provided with a bent portion along the longitudinal direction as shown in FIG. can do. Further, if the angle of the support surface of the retainer constituting member 51 is changed as shown in FIG. 3C, the installation angle of the shock absorber 3 can be inclined by supporting the flat support base 2 on a plane.

The shock absorber 1 according to the present invention is used as a support device for a pallet such as a precision instrument, a compressor or a generator that generates vibration as in the above-described embodiments, and as a display stand for a work of art as shown in FIG. Earthquake resistance and impact prevention can be achieved. Moreover, since a load resistance can be set with the diameter and the number of turns of the wire rope 4, it can be used as a seismic device for a building such as a house or a structure.
