Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a buffer pedestal for supporting equipment, particularly equipment having a vibration source such as a small motor generator.

Conventionally, as shown in the perspective view of FIG. It is comprised of a carburetor 5 that supplies air, an air cleaner 6 that supplies air to this carburetor 5, and the like. A buffer pedestal 7 made of an elastic material such as rubber for supporting the generator 1 is disposed on the bottom of the small-sized motor generator 1 (hereinafter simply referred to as a generator). The head of a bolt 8 is installed in the upper part of the buffer pedestal 7, and the bolt 8 is screwed into the lower frame 9 of the generator 1 and locked with a nut 10. As shown in the partial sectional view and bottom view of FIG. A hole 7b is formed in the hole 7b.

By the way, according to the conventional buffer pedestal 7 described above, the bottom surface 7a of the buffer pedestal 7 is formed in a flat shape, so when the generator 1 is installed, the installation surface (not shown) and the bottom surface of the buffer pedestal 7 are flat. The contact area with 7a is large, and therefore the contact surface pressure per unit area is small. Therefore, the amount of deformation of the buffer pedestal 7 in the height H direction is small, and when the generator 1 is driven and vibrations are generated, the contact between the installation surface and the buffer pedestal 7 is not maintained, and as a result, the power generation There was a drawback that aircraft 1 moved. Furthermore, the handle 11 (first
When trying to move the generator 1 by grasping the part shown in FIG.

In view of the above-mentioned drawbacks of the conventional buffer pedestals, the present invention provides a buffer pedestal that does not move due to vibrations etc. while the equipment is in operation, and can be easily moved when changing the installation location. The purpose is to

In order to achieve this purpose, the present invention forms a convex part in the center of the bottom of the buffer pedestal that protrudes beyond its outer periphery, and also forms ribs that support this convex part radially around the convex part. It is something.

An embodiment of the buffer pedestal according to the present invention will be described in detail below.

FIGS. 2a and 2b are a partial sectional view and a bottom view of essential parts showing an embodiment of the buffer pedestal according to the present invention, and the same parts as in FIGS. 1a and 1b are designated by the same reference numerals.

As shown in FIG. 2a, the bottom surface 2 of the buffer pedestal 20
A convex portion 20b having a hemispherical tip is integrally formed in the center portion of 0a. This convex portion 20b
The lower end 20c protrudes below the lower end 20θ of the outer peripheral edge 20d of the buffer pedestal 20. Moreover, as shown in the bottom view of FIG.
Ribs 20f are mounted radially around the center and have an inclination angle α. Therefore, generator 1
(Fig. 1a), only the lower end 20c of the convex portion 20b of the buffer pedestal 20 is the installation surface (not shown).
, the contact surface pressure of the convex portion 20b increases, and the amount of deformation of the convex portion 20b in the height H direction also increases. Therefore, the vibrations generated during operation of the generator 1 are caused by the convex portion 20b and the rib 2 that is grounded on the installation surface according to the deformation of the convex portion 20b.
It is absorbed by the 0f portion, and the buffer pedestal 20 and the installation surface do not come apart during operation.

Moreover, since the convex portion 20b is reinforced by the ribs 20f, the convex portion 20b will not be deformed and the contact area with the installation surface will not increase when the generator 1 is pulled and moved.

Since the present invention has the above-mentioned configuration, equipment such as the engine generator does not move due to vibration during operation, and furthermore, when trying to change the installation position of equipment such as the engine generator, it is easy to It can be moved.
