Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a leg structure of a diaphragm equipped with a vibration device that generates vibrations or deep bass sounds.

(Prior Art) Conventionally, as a leg structure of this type of diaphragm, the structure shown in FIG. 2 is known. In this leg structure, a total of four leg members 53 made of a hard material such as wood are attached using adhesive to the lower peripheral edge (four corners) of the diaphragm 52, which has a starter device 51 approximately in the center. It is installed.

In addition, a device disclosed in Japanese Utility Model Application Publication No. 197782/1982 is also known, and in this leg structure, a cushion material, a square piece of hard material, and a rubber cushioning material are sequentially adhered to form a vertically long leg. In addition to configuring the components,
The leg members support the joint portions of each diaphragm from below.

(Problem to be solved by the invention) However, in the former leg structure, the leg member 5
3 is attached to the diaphragm 52 using adhesive, the work of attaching the leg members 53 is troublesome, and since the attaching of the leg members 53 depends on adhesives, the adhesive may become damaged during long-term use. There was a problem in that the leg members 53 were deteriorated by the vibrations generated in the leg members 51 and the attachment of the leg members 53 became unstable. Furthermore, when the leg members 53 are installed on the floor, the vibrations are transmitted to the floor and cause noise.

In addition, in the latter leg structure, the leg members have a cushion material and a cushioning member, so unlike the former, vibrations are not transmitted to the floor surface and generate noise, but there is no need to use a special connection means and the diaphragm is used. Since the leg members are supported only from the bottom, there is a problem that the supporting position of the leg members is likely to shift due to the vibrations and shocks caused when performing aerobics, dancing, or other exercises on the diaphragm.

Furthermore, in each of the conventional leg structures described above, it is necessary to provide mounting holes for the legs in the diaphragm as well as mounting holes for mounting the vibrating devices, and there are as many mounting holes as there are vibrating devices. The problem is that the structure of the diaphragm becomes complicated.

In view of the above-mentioned conventional problems, the purpose of the present invention is to buffer vibrations and shocks, and to attach the legs to the diaphragm easily and reliably. To provide a leg structure of a diaphragm that can simplify the structure of the diaphragm by serving as a mounting hole.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides mounting holes for at least three leg members arranged in a diaphragm so that connecting lines connecting the centers form a polygon. In the leg structure of the diaphragm, at least one of the mounting holes is a through hole, and the lower part of the mounting hole formed by the through hole and the mounting holes other than the mounting hole formed by the through hole are made of a hard material. A cylindrical fitting member made of material is fitted, and the head of the leg member made of an elastic material is fitted into the fitting member, and the upper part of the mounting hole formed by the through hole is provided with the It is characterized by incorporating a vibration device.

(Function) According to the present invention, when the diaphragm is installed on the floor, the vibrations generated by the oscillating device and the impact when exercising on the diaphragm are buffered and alleviated by the leg members made of elastic material. , noise generation and driving hazards to human bodies can be prevented. In addition, since each leg member is fitted into the mounting hole through a fitting member made of a hard material, the leg member can be easily and reliably attached to the diaphragm by utilizing its own elastic force. be able to. Furthermore, part of the mounting hole is formed as a through hole, and while the legs are attached from the lower opening of this mounting hole, the vibration device can be attached from the upper opening of this mounting hole, so the upper part of this mounting hole vibrates. It is used as a mounting space for the device, and there is no need to separately form a mounting hole for the vibration device on the diaphragm.
