FR2846717A3 - Base for air compressor has H-shaped frame with support legs having ribbed rubber underlayer - Google Patents

Abstract

The base for an air compressor has a H-shaped frame (1) of flexible material and four legs (12). the h-shaped frame has four lugs (11) having inner threads. Each leg has a rubber pad at its end (121). the legs have a rubber underlayer attached to it. The underside of the rubber layer can have ribs.

Description

The invention relates to improving the structure of the base of a mini

air compressor.

  Referring to Figure 1, the conventional air compressor is mounted on a base Ai, which is equipped with a plurality of the rubber packings A2 in order to

  reduce the vibrations produced by the air compressor in operation.

  However, such a base cannot effectively prevent the air compressor from

  operation to move nor absorb the noise produced.

  It is therefore an object of the present invention to provide an improved basis for an air compressor which can obviate and alleviate the disadvantages

mentioned above.

  The primary object of the present invention is to provide an improved base i5 for an air compressor which will act as a shock absorber.

  Another object of the present invention is to provide an improved base for an air compressor, which can absorb the vibration force generated by the air compressor, and thereby reduce noise. Another object of the present invention is to provide an improved base for an air compressor which allows the air compressor to operate more efficiently.

softness, and more regularly.

  According to the preferred embodiment of the present invention, the base of the

  air compressor includes an arched H-shaped element made of elastic material and having four legs. This arched H-shaped element is also fitted, on top, with a plurality of small internally threaded tubes.

  Each of these legs has protruding ribs at its end, and is fitted with a rubber lining, adapted to engage at the end of each leg.

  The invention will be better understood using the following description of the

  preferred embodiment of the compressor base of the invention, with reference to the accompanying drawing, in which: - Figure 1 shows an air compressor of the prior art; - Figure 2 shows a perspective view of a compressor with its base according to the present invention; Figure 3 shows an exploded view of the base of the present invention; - Figure 4 shows is a top view of the base of the present invention; - Figure 5 shows is an end view and a side view of a rubber gasket of the base of the present invention and - Figure 6 illustrates the operating principle of the base and the

  compressor according to the present invention.

  The following description is that of the preferred embodiment of the invention, but the applicant does not intend to limit itself to this mode of

  production. Referring to Figures 2, 3 and 4, the base of a mini air compressor 10 according to the present invention comprises an arcuate H-shaped element 1, made of an elastic material. On the element 1 are arranged four small internally threaded tubes 1 1 so that the air compressor 10 can be firmly mounted on

  the base by screws passing through these small internally threaded tubes 1 1.

  With reference to FIGS. 3 and 4, the arched H-shaped element 1 is formed by four legs 12 shaped to be inserted in rubber linings 2 which serve as shock absorbers for the base. The end of each leg 12 has protruding ribs 121 to allow a firm hold between the leg

12 and the rubber seal 2.

  Referring to Figure 5, each rubber lining 2 comprises a curved bottom 21 to come into contact with the ground. The bottom of the rubber liner 2 includes a plurality of protrusions 211 to provide the rubber liner 2 with greater adhesion, thereby allowing the base to

stand firmly on the ground.

  Referring to Figure 6, when operating, the air compressor 10 is mounted on the small internally threaded tubes 1 1 of the base and is therefore integral with the latter; as the base has an arched H-shaped element 1, made of an elastic material, it behaves like a damper for the air compressor 10, thereby absorbing the vibration force produced by the air compressor 10 and therefore reducing noise. In addition, the air compressor 10 can operate more

softness, and more regularly.

  Although the figures do not allude to it, it will be readily understood that the arched H-shaped base 1 can be modified and replaced by an elongated and arched rectangular element.
