FIG. 2 is a diagram illustrating a method for adjusting the support height of the housing with the insulator shown in FIG. It is a figure which shows the modification of a damping member.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an insulator 1 according to this embodiment, and FIG. 2 is a plan view thereof.

  As shown in FIGS. 1 and 2, the insulator 1 includes a support member 4 that supports the leg K, and a receiving member 2 that is placed on a support surface S that supports the leg K and receives the support member 4. ing. In the present embodiment, a case where the leg portion K of the piano is supported by the insulator 1 as a housing will be described.

  The support member 4 has a shape in which a bottomed cylindrical support portion 42 is extended from the lower surface of the inner peripheral edge of the annular flat plate, and the support recess 40 extends upward from the inner bottom surface of the support portion 42. Is opened at the center of the upper surface. On the lower surface of the support member 4, there are provided fixing recesses 43 for fixing the vibration absorbing member 5 at equal intervals around the upper end opening of the support recess 40.

  The vibration absorbing member 5 is for supporting the support member 4 on the receiving member 2, and is configured by fixing a conical convex portion 52 to the lower end of a spring member 51 that is curved in a coil shape. The vibration absorbing member 5 has the upper end portion of the spring member 51 accommodated in the fixed concave portion 43 of the support member 4 and is fixed to the inner bottom surface of the fixed concave portion 43 by using an adhesive or the like. It is located below.

  The receiving member 2 is composed of an annular flat plate body having an accommodation hole 21 at the center. The accommodation hole 21 penetrates the receiving member 2 from the upper surface to the lower surface, and has a circular opening shape. The accommodation hole 21 is for accommodating a support portion 42 of the support member 4 to be described later and positioning the support member 4 in the horizontal direction with respect to the receiving member 2.

  The receiving member 2 is provided with six female screw holes 22 in an annular shape centered on the receiving hole 21 at equal intervals. Each female screw hole 22 penetrates the receiving member 2 from the upper surface to the lower surface, and has a female screw portion on the inner peripheral surface. A support position adjusting member 3 for adjusting the support position of the vibration absorbing member 5 in the receiving member 2 is screwed into the female screw hole 22.

  The support position adjusting member 3 has a cylindrical shape, and has a male screw portion 3a that is screwed into the female screw portion of the female screw hole 22, and a cone for receiving a convex portion 52 of the vibration absorbing member 5 to be described later. A fitting portion 3b for fitting a tool for screwing the support position adjusting member 3 into the female screw hole 22 is provided on the lower surface.

  As shown in FIG. 3, the insulator 1 places the receiving member 2 in which the support position adjusting member 3 is screwed into the female screw hole 22 on the support surface S, and places the support portion 42 in the receiving hole 21 of the receiving member 2. By inserting the convex portions 52 of the vibration absorbing member 5 inserted from above and extending downward from the respective fixed concave portions 43 of the supporting member 4 into the concave portions 31 of the supporting position adjusting member 3, the supporting member 4 is replaced by the vibration absorbing member 5. The support member 2 is used while being supported. The piano leg K supported by the insulator 1 is accommodated in the support recess 40 of the support member 4 and supported by the inner bottom surface of the support recess 40.

  Before the receiving member 2 is placed on the support surface S, by adjusting the screwing amount of the support position adjusting member 3 to the female screw hole 22, the support position adjusting member 3 from the support surface S of the vibration absorbing member 5 is adjusted. The support height H can be adjusted to increase from the height H1 shown in FIG. 3 to the height H2 shown in FIG. 4, or vice versa. Accordingly, the support height of the piano leg K from the support surface S is also adjusted.

  Further, by individually adjusting the screwing amount of the support position adjusting member 3 to each female screw hole 22 provided in the receiving member 2, the support height of each vibration absorbing member 5 at the support position adjusting member 3 is also individually adjusted. be able to. Therefore, all of the vibration absorbing members 5, any of the four vibration absorbing members 5 fixed to any two sets of the fixed concave portions 43 facing each other, and any of the three vibration absorbing members 5 fixed by the fixed concave portions 43 arranged alternately. Thus, the support member 4 can be stably supported by the receiving member 2.

  For example, as shown in FIG. 5, all the vibration absorbing members 5 a to 5 f (see FIG. 5A) fixed to the fixing recesses 43 a to 43 f and two sets of vibration absorbing members 5 a, 5 b, 5 d, and 5 e facing each other (FIG. 5). (See (b)), or the support member 4 is received by the receiving member 2 at 6 points, 4 points, or 3 at 3 vibration absorbing members 5a, 5c, 5e (see FIG. 5 (c)) arranged alternately. It can be supported stably in terms of points.

  For this reason, the weight applied to the vibration absorbing member 5 is adjusted by selecting whether the support member 4 is supported at 6 points, 4 points, or 3 points according to the weight of the piano provided with the leg K. Is possible. For example, when the support member 4 is supported at 6 points, it is applied to the support member 4 with 6 vibration absorption members 5, when it is supported at 4 points, it is applied with 4 vibration absorption members 5, and when it is supported at 3 points, it is applied with 3 vibration absorption members 5. Each weight will be shared. For this reason, the amount of bending of the spring member 51 falls within an appropriate range suitable for vibration absorption by selecting whether to support at 6 points, 4 points, or 3 points according to the weight received by the support member 4. The weight applied to the vibration absorbing member 5 can be adjusted.

  Further, the support height from the support surface S of the support member 4, that is, the support height from the support surface S of the leg K is adjusted by adjusting the support height of the vibration absorbing member 5 at the support position adjusting member 3. it can. For example, in the example shown in FIG. 5 (a), the support height of the vibration absorbing members 5a to 5f, in the example shown in FIG. 5 (b), the support height of the vibration absorbing members 5a, 5b, 5d, 5e, In the example shown, the support height from the support surface S of the leg K when the support member 4 is supported at 6 points, 4 points, and 3 points by adjusting the support heights of the vibration absorbing members 5a, 5c, 5e. Can be adjusted.

  Thus, in the insulator 1 of this embodiment, since the six vibration absorbing members 5 arranged annularly at equal intervals are supported by the support position adjusting members 3 arranged annularly at equal intervals, all (six ), 2 sets of (4) vibration absorbing members 5 arranged opposite to each other, or three vibration absorbing members 5 arranged alternately, with each supporting member 4 being stably supported, The support height of the leg K can be freely adjusted while keeping the weight applied to the vibration absorbing member 5 within an appropriate range suitable for the vibration absorption of the spring member 51. As a result, it is possible to cause the insulator 1 to exhibit a high vibration absorbing action, to improve the modulation distortion due to the vibration of the piano and to reduce the vibration of the support surface S, and to reproduce the original sound of the piano clearly. Moreover, it is possible to prevent noise caused by the piano sound being transmitted to the support surface S.

  In the embodiment described above, the case where the vibration absorbing member 5 is configured using the spring member 51 that is curved in a coil shape has been described. However, the structure of the vibration absorbing member 5 is arbitrary as long as it is disposed between the support member 4 and the receiving member 2 and can be elastically supported by the receiving member 2. For example, like a vibration absorbing member 5A shown in FIG. 6A, a spiral spring member 51A having a spiral shape gradually reduced from the upper end to the lower end may be used. Moreover, you may comprise by the spring member 51B by which the lower end part was formed in the spiral shape like the vibration absorption member 5B shown in FIG.6 (b).

  Moreover, although the said embodiment demonstrated the case where the convex part 52 of the vibration absorption member 5 was received by the conical recessed part 31 provided in the upper surface of the receiving member 2, the vibration absorption member 5 needs to be provided with the convex part 52. For example, the lower end of the spring member 51 may be received by the concave portion 31 on the flat bottom surface. Further, the concave portion 31 provided in the vibration absorbing member 5 may receive the convex portion 52 provided in the support position adjusting member 3. Further, the convex portion 52 may be formed not only at the lower end of the spring member 51 but also at the upper end.

  If the vibration absorbing member 5 is disposed between the support member 4 and the receiving member 2 and can be elastically supported by the receiving member 2, the vibration absorbing member 5 is fixed to either the support member 4 or the receiving member 2. In addition, it may be fixed to either, or may not be fixed to any. For example, when the end portion of the vibration absorbing member 5 having the convex portion 52 is fixed to the support member 4 or the receiving member 2, the tip of the convex portion 52 is fixed to the support member 4 or the receiving member 2 by screwing or the like. can do.

  Further, the engaging portion provided on the support member 4 and the engaging portion provided on the receiving member 2 are engaged, or the screw portions provided on the supporting member 4 and the receiving member 2 are screwed together. The support member 4 may be elastically supported on the receiving member 2 by the vibration absorbing member 5 by releasing the integration when the insulator 1 is used.

  Further, in the embodiment, the case where the leg portion of the piano is supported by the support member 4 is illustrated, but various devices such as an electric washing machine having a vibration source inside, a refrigerator, a speaker, and the like that need vibration absorption. It can also be used to support the housing. Moreover, although the said embodiment demonstrated the case where the leg part K of a piano was accommodated in the support recessed part 40 and supported, as a structure which mounts a housing | casing on the upper surface of the support member 4 without providing the support recessed part 40. Good. Moreover, the horizontal positioning method of the support member 4 with respect to the receiving member 2 is arbitrary.

  In the above embodiment, the case where the support position adjusting member 3 is screwed into the female screw hole 22 provided in the receiving member 2 and the vibration absorbing member 5 is fixed to the fixing recess 43 provided in the support member 4 has been described. However, the vibration absorbing member 5 may be fixed to the fixing recess provided in the receiving member 2, and the support position adjusting member 3 may be screwed into the female screw hole provided in the support member 4.
