DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to stands for enhancing performance of audio components and in particular enhancing performance of audio amplifiers.
BACKGROUND OF THE INVENTION
Presently, stands are used for a number of components of home audio systems particularly, with turntables and speakers to act as isolation devices for isolating the components from vibration. It has been thought that certain of the components such as amplifier or receivers are not directly affected by vibration or other interference and hence, it has been thought that it was not necessary to provide for isolation devices for such components.
SUMMARY OF THE INVENTION
The present invention provides a stand for enhancing performance of an audio component. The stand comprises a hollow body having a supporting base and tapering upwardly inwardly from the supporting base to a top seating surface for the audio component. The stand is made from an insulating material for isolating the audio component from the surface on which it is supported through the stand.
BRIEF DESCRIPTION OF THE DRAWINGS
The above as well as other advantages and features of the present invention will be described in greater detail according to the preferred embodiments of the present invention in which:
FIG. 1 is a perspective view of an amplifier supported by a plurality of stands each of which is made in accordance with a preferred embodiment of the present invention;
FIG. 2 is a perspective view of one of the stands used in FIG. 1; and
FIG. 3 is a sectional view of the stand of FIG. 2.
DETAILED DESCRIPTION ACCORDING TO THE PREFERRED EMBODIMENTS OF THE PRESENT
INVENTION
FIG. 1 illustrates a typical audio amplifier 10 supported by a plurality of audio stands 12 made in accordance with a preferred embodiment of the present invention. Because these stands are relatively small and positioned at spot locations, typically a number of stands, only two of which can be seen in FIG. 1, are used to support the amplifier.
The stands are a height, e.g. preferably from about 1 to 5 inches most preferably from about 1.5 to 3.5 inches, to effectively lift the amplifier from the supporting surface on which the stands themselves are placed while maintaining stability of the amplifier.
Each of these stands has the function of lifting the amplifier off of the supporting surface on which the amplifier would otherwise rest. This supporting surface is subject to different conditions such as the transmission of electrical signals, heat buildup, etc. which pass through the supporting surface. This is true even when the supporting surface is made from a material with low conductivity properties and normally the amplifier would sit with its entire bottom surface on or immediately next to the supporting surface where the amplifier would be subject to any transmissions flowing through the supporting surface. These transmissions then adversely affect performance of the amplifier.
However, in accordance with the present invention, the amplifier is lifted off of and isolated from the supporting surface by the stands 12. The stands themselves have a hollow construction and present only a relatively thin lower edge 14 forming the base of the stands. This thin lower edge, in combination with the small size of the stand, ensures a very small surface or transmission area through the stand to effectively block transmissions from the supporting surface to the amplifier. In addition, each of the stands has an upward inward taper with an actual thinning of the material upwardly through the stand as best seen in FIG. 3 of the drawings to provide a sink effect restricting the flow of any adverse transmissions upwardly along the stand. The stand then terminates in a top surface 16 which as again seen in FIG. 3 of the drawings has a very small surface area for contact with the amplifier. This again enhances the isolation of the amplifier through the stand relative to the supporting surface.
In the preferred embodiment of the invention as shown, stand 12 has a hollow slightly t
