Description

  The present invention mainly attaches to the lower legs of furniture such as chairs and tables to absorb the impact sound that occurs when these chairs are moved and prevent the noise from traveling downstairs. The present invention relates to a soundproofing device for a club.

Conventionally, as a member to be mounted on a leg portion of furniture, for example, a leg end surface support structure such as furniture as shown in Patent Document 1 has been proposed. According to this structure, the cushioning material is interposed between the end portion of the pipe and the elastic support member that supports the end portion, and the furniture is stably supported.
Utility Model Registration No. 3077205

  In the support structure described in Patent Document 1, since it is necessary to insert a cushioning material into the pipe material, furniture to which this support structure is applied is limited to furniture whose legs are formed of pipe material. It is difficult to attach to the legs other than the material. Therefore, the support structure of Patent Document 1 has a disadvantage that furniture that can be worn is limited.

  In addition, since this support structure has a buffering material interposed between the end of the pipe and the elastic support member that supports the end, there are two buffering materials and an elastic support member at the end of the pipe. It is in a state of being joined heavily. For this reason, when a strong impact is applied to the end portion of the pipe, there is a risk that the impact sound will resonate on the floor surface through these cushioning materials and elastic support members. In other words, this support structure was originally designed to reduce the thickness of the elastic material in order to prevent the elastic material having a large thickness from bending, so that the thin elastic material is in close contact with the end of the pipe. If so, the effect of absorbing the impact is reduced, and it becomes difficult to sufficiently mitigate the impact sound.

  Therefore, the present invention has been devised to solve the above-mentioned problems. By mounting the chair on the lower end of the leg of furniture such as a chair or table, the impact sound generated when these chairs are moved is generated. The object of the present invention is to provide a soundproofing device for a leg portion of furniture that can be absorbed to prevent noise to the downstairs and the like, and can be thinly formed on the whole and can be easily attached to the leg portion.

  According to a first means of the present invention, there is provided a plurality of elastic protrusions in a soundproofing device for a leg which is bonded to a lower end surface of a leg P of furniture or the like and is provided so as to absorb an impact sound generated by movement of the furniture or the like. 2, a sound-insulating layer 3 made of a foam material supported inside the saucer body 1 and supported on the protrusions 2, and an adhesive layer provided on the top surface of the sound-insulating layer 3 This is because it is composed of four.

  In the second means, the soundproof layer 3 is made of foam material of two upper and lower layers, and is provided so as to lock the soundproof layer 3 with a locking protrusion 5 provided on the inner periphery of the tray 1. The upper soundproof layer 3 is provided so as to rise above the upper opening of the tray 1, and the adhesive layer 4 provided on the upper surface of the soundproof layer 3 is pressed by the leg P. Sometimes, it is provided so as to be housed in the saucer body 1 together with the upper soundproof layer 3.

  The third means is that the tray 1 is made of an elastomer rubber, and the protrusion 2 is made of a low resilience rubber.

  The tray 1 of the fourth means is a means for solving the problem that the fluorine coating layer 6 is applied to the surface in contact with the floor surface.

  According to claim 1 of the present invention, a synthetic rubber tray 1 having a plurality of elastic projections 2 therein, and a soundproof layer made of a foam material housed in the tray 1 and supported on the projection 2 3 and the adhesive layer 4 provided on the upper surface of the soundproof layer 3, the receiving body 1, the projection 2 and the soundproof layer 3 have a synergistic effect, and the impact generated when the chair or the like is moved. It is possible to prevent noise to the downstairs and the like by absorbing sound, particularly sound such that the leg P hits the floor. Moreover, the tray 1 can be formed thin, and the adhesive layer 4 can be attached to the legs P of any furniture.

  Further, according to claim 2, by providing the locking ridge 5 on the inner periphery of the saucer body 1, the locking ridge 5 is used to lock the soundproof layer 3 made of two layers of upper and lower foams. An effective soundproofing effect can be obtained. Further, since the soundproof layer 3 is locked by the locking protrusion 5, the soundproof layer 3 can be reliably held in the tray body 1.

  Moreover, the adhesive layer 4 provided on the upper surface of the soundproof layer 3 is provided so as to be housed inside the saucer body 1 together with the upper soundproof layer 3 when the soundproof layer 3 is pressed by the legs P. As a result, attachment to the leg portion is facilitated, and dust and dirt are prevented from adhering to the periphery of the adhesive layer 4 and can be used cleanly.

  Further, according to the third aspect of the present invention, since the tray body 1 is made of elastomer rubber and has the projections 2 formed of low resilience rubber, the tray body 1 itself can efficiently absorb the impact. As a result, the tray 1 can be formed thin.

  According to claim 4, since the tray body 1 is provided with the fluorine coating layer 6 on the surface in contact with the floor surface, when the furniture is pulled in the horizontal direction, the resistance between the floor surface and the floor surface becomes extremely small. Since the furniture slides well, the noise of the furniture due to friction can be prevented. Further, by applying the fluorine coating layer 6 to the bottom surface of the tray 1, there is an advantage that dust and dust are difficult to adhere around the bottom surface.

  Thus, according to the present invention, by attaching to the lower end of the leg of furniture such as a chair or table, the impact sound generated when these chairs are moved is absorbed to prevent noise to the downstairs, etc. In addition, it is possible to form a thin film as a whole and to provide various practically beneficial effects such as easy attachment to the legs.

  The best mode of the present invention is a receiving tray 1 made of synthetic rubber having a plurality of elastic projections 2 inside, and a soundproof layer made of a foam material housed in the receiving tray 1 and supported on the projections 2. 3 and an adhesive layer 4 provided on the upper surface of the soundproof layer 3. The soundproof layer 3 is made of two upper and lower foam materials, and is provided so as to lock the soundproof layer 3 with a locking protrusion 5 provided on the inner periphery of the tray 1. The upper soundproof layer 3 </ b> B is provided so as to rise above the upper opening of the tray 1, and the adhesive layer 4 provided on the upper surface of the soundproof layer 3 is pressed by the leg P. Sometimes it is provided so as to be housed inside the saucer 1 together with the upper soundproof layer 3. The saucer body 1 is formed of elastomer rubber, and the protrusion 2 included therein is formed of low resilience rubber. The initial object is achieved by applying a fluorine coating layer 6 to the surface of the tray body 1 in contact with the floor surface.

  The basic configuration of the present invention is composed of a saucer body 1, a soundproof layer 3, and an adhesive layer 4, and is bonded to the lower end surface of a leg P of furniture or the like (see FIG. 1).

  The saucer body 1 is a substantially bowl-shaped member made of synthetic rubber such as elastomer rubber, and a plurality of elastic protrusions 2 are provided inside the saucer body 1 (see FIG. 2). Although the saucer body 1 shown in FIG. 4 has a planar circular shape, it may be formed in a planar rectangular shape as shown in FIG. 5, and the shape of the saucer body 1 can be arbitrarily changed. And the sound-insulation layer 3 mentioned later is accommodated in this saucer body 1. FIG. Moreover, in order to lock the stored soundproof layer 3 inside the saucer body 1, the latching protrusion 5 is provided in the inner periphery of the saucer body 1 (refer FIG. 2).

  The protrusion 2 arranged in the saucer body 1 is formed of a low resilience rubber such as butyl rubber, for example. In the example of illustration, the state which has arrange | positioned the some protrusion 2 which comprised substantially cylindrical shape to concentric form is shown. The projection 2 has a function of absorbing the impact by the projection itself, and the projection 2 supports the soundproof layer 3 housed in the saucer body 1. Moreover, although the illustrated protrusion 2 is formed integrally with the saucer body 1, the protrusion 2 formed separately may be accommodated in the saucer body 1.

  The soundproof layer 3 is a member that is housed inside the saucer body 1 and supported on the protrusions 2 inside the saucer body 1, and is formed of a foam material. In particular, the soundproofing effect can be enhanced by forming the soundproofing layer 3 from two upper and lower foam materials. In the embodiment, a so-called single-foam foam material having an independent foam structure and a so-called continuous foam material having a continuous foam structure are provided in two layers. In the illustrated example, two layers of the lower urethane 3A and the upper urethane 3B are bonded, the lower urethane 3A is disposed on the lower surface of the locking ridge 5, and the lower urethane 3A is disposed on the upper portion of the locking ridge 5. Yes. And upper urethane 3B is provided so that it may rise rather than the opening upper part of saucer body 1, and when receiving the load from leg part P, this upper urethane 3B is provided so that it may be pushed inside saucer body 1. (See FIG. 3).

  The adhesive layer 4 is provided on the upper surface of the soundproof layer 3, that is, the upper surface of the upper urethane 3B in the illustrated example. The adhesive layer 4 uses a double-sided tape, but can be changed to other adhesive means. When a double-sided tape is used, it can be easily adhered to the bottom surface of the leg P by simply peeling off the release paper (not shown). In addition, since the adhesive layer 4 is provided on the upper surface of the upper urethane 3B, the adhesive layer 4 is pushed into the tray 1 together with the upper urethane 3B when receiving a load from the leg portion P. (See FIG. 3). As a result, the peripheral edge of the adhesive layer 4 is not exposed to the outside in a state where the peripheral edge of the adhesive layer 4 is pushed into the saucer body 1, so that it is possible to prevent dust and dirt from adhering to the peripheral edge.

  When the soundproofing effect of the present invention was tested, the following results were obtained. According to this experiment, when the table leg P having a weight of 6 kg was dropped from a height of 2 cm onto the floor surface, the falling sound was 97 db. When this device comprising the saucer 1 having a diameter of 28 mm and a height of 6.5 was bonded to the leg P and dropped, the falling sound was 62 db, and a sound-proofing effect of -35 db was recognized. Similarly, when falling sound was measured when another material was bonded to the leg P, it was 88db (-9db) for general felt, 85db (-12db) for hard felt, and 72db (-25db) for rubber cap. Therefore, it is proved that the soundproofing effect of the present invention is excellent.

  In addition, each structure of the example of illustration is only one Example of this invention, The shape, material, etc. of the saucer body 1, the protrusion 2, or the sound-insulation layer 3 and the contact bonding layer 4 can be selected arbitrarily, Changes can be made freely without departing from the scope of the gist.
