DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for connecting and supporting a disposer for treating kitchen waste to a sink by a rubber connecting tube and a compression spring.

[0002]

2. Description of the Related Art Conventionally, when a small disposer for household use is attached to a drain of a sink, a mounting pipe watertightly attached to the sink by a packing and a ring nut, and an inlet at an upper end of the disposer. Is connected to a thick rubber connecting pipe made of natural rubber or synthetic rubber, and the upper and lower sides of this connecting pipe are fastened and fixed to the mounting pipe and the inlet with a tightening band. They are connected so that vibration is not transmitted. However, in the case where the rubber connecting pipe is attached in this way, the weight of the disposer is added to the rubber connecting pipe so that the rubber is stretched,
Rubber elasticity was impaired, and sufficient vibration and soundproofing effects could not be obtained.

For this reason, Japanese Patent Application No. Hei.
A spring mounting seat provided on the member on the mounting tube side and a spring mounting seat provided on the disposer side are provided, and between both mounting seats,
A mounting device with a tension spring is shown. Further, in the anti-vibration mounting mechanism disclosed in Japanese Patent Application Laid-Open No. 11-169740, a main body side cylinder fitted to an input port is provided in a disposer together with a drain side cylinder attached to a drain of a sink, This drain port side cylinder and the main body side cylinder are connected by a flexible cylinder, and the drain port side cylinder and the main body side cylinder are
Each of the brim-shaped supports in the lateral direction protrudes, and support rods provided with stoppers at both ends via elastic bushes are fitted into holes provided at a plurality of locations facing each other. An elastic cylinder (compression spring in FIG. 3) between the collar-shaped support of the main body side cylinder and the stopper at the end of the support rod.
And the load of the disposer is received by the vibration-proof mounting device, and the flexible cylinder is simply configured as a cover.

[0004]

SUMMARY OF THE INVENTION However, Japanese Patent Application No. Hei.
No. 573 uses a tension spring, so when attaching it, it is necessary to hook the spring itself while pulling the spring itself, which is not only troublesome, but also has a drawback such as difficulty in adjusting the spring pressure. . Also, Japanese Unexamined Patent Application Publication No.
In the case where the disposer and the sink are attached to each other by a support rod and an elastic cylinder or a compression spring surrounding the support rod as in JP-169740, a flexible cylinder is used instead of a structure in which the disposer is connected and supported by a rubber connection pipe. Is merely a cover, and is connected and held by a brim-shaped support and a vibration-proof mounting device composed of an elastic cylinder and a compression spring, and receives the entire weight of the disposer by the vibration-proof mounting device.
Therefore, it is necessary to give sufficient strength to the elastic cylindrical body, not only the structure becomes complicated, but also the rigidity of the elastic cylindrical body must be increased, and it becomes rather difficult to obtain an anti-vibration effect, Since the support rod is lengthened to increase the vibration-proofing effect by shaking, there are disadvantages such as an increase in the size of the connecting portion.

In view of the above, the present invention relates to a compression spring device in which a sink-side mounting pipe and a disposer input port are connected by a connecting pipe made of rubber to reduce the weight of the disposer applied to the rubber connecting pipe. Is provided to protect the rubber connecting pipe and prevent the vibration damping function from being deteriorated.

[0006]

For this purpose, the mounting pipe attached to the drain of the sink and the input port at the top of the disposer are connected by a rubber connecting pipe, and the mounting pipe is surrounded by the rubber connecting pipe and the sink. And a lower support plate attached to the lower end surface of the rubber connecting pipe so as to contact the lower end surface of the rubber connection pipe around the input port, and one end of the upper support plate is provided at several places between the upper support plate and the lower support plate. And a support rod attached to one of the lower support plate and having a spring receiving piece at the other end; and a support rod integrated with or separately from the support plate to the other of the upper support plate and the lower support plate. And a compression spring acting between the spring receiving piece and the spring receiving plate and acting in the direction of pushing up the lower support plate around the support rod.

It is desirable that the support rod be swingably attached to one of the upper support plate and the lower support plate, and the spring receiving plate be swingably connected to the other support plate via an attachment member. be able to. Further, the spring receiving plate is fixed integrally to the other support plate, or formed in a holding frame swingably attached to the supporting plate, and the holding frame is connected to the upper supporting plate or the lower supporting plate via an attaching member. Can be attached to The holding frame and the mounting member can be assembled as separate members or formed integrally.
