SUPPORTS FOR SOUND REPRODUCTION EQUIPMENT
The present invention relates to a support, for example, a table or a shelf, for sound reproduction equipment such as record turntables, compact disc players, tape players, amplifiers, loud speakers, etc.
It is appreciated, especially by hi-fi enthusiasts, that the nature of the surface on which a piece of equipment is placed will affect its performance in relation to the quality of sound which is reproduced, particularly in the case of a record turntable. For example, there are many materials and structures which are known to affect performance adversely across either part or the whole of the audible frequency spectrum.
Consequently there are a number of purpose built supports for sound reproduction equipment available on the market to the discerning hi-fi enthusiast, some costing as much as from £300 to 400. However, I have found that even reputedly the best of these still leave something to be desired, and I believe my invention provides a support which enables a quality of sound reproduction to be obtained which is far superior to that obtainable from supports currently available.
According to the invention there is provided a support for sound reproduction equipment comprising a substantially rigid support frame which is devoid of tubular elements and closed cavities in its construction, and a glass plate mounted on, and supported solely by, a plurality of substantially pointed members carried by the frame, the glass plate defining the surface on which the equipment is to be placed.
Preferably the support frame is made of metal, preferably iron or steel, and is preferably of a welded construction. A particularly strong and rigid frame may be obtained by using angle-section members for the main components of the frame.
The pointed members for supporting the glass plate are preferably adjustable relative to the frame so that the glass plate can be levelled, and preferably they are formed by screw-threaded spikes received in correspondingly threaded holes in the frame.
The glass plate is preferably of plate glass and may be provided on its under surface with locating rings arranged so that the pointed members will contact the glass within the rings, but without contacting the rings themselves, when the plate is correctly positioned on the frame. These rings will serve not only to position the plate but also to retain it on the frame in the event of the support being knocked accidentally.
There may, of course, be more than one glass plate mounted on the support frame in a manner similar to each other, thus providing the support with more than one surface on which equipment may be placed.
The support may take the form of a shelf or a table.
In the case of a shelf, the frame will include members which are designed to be attached to a wall. In the case of a table, however, the frame will be designed to be free standing, and is preferably provided with adjustable feet for ensuring that the support will be firmly supported on the floor. The adjustable feet may be formed by further substantially pointed screwthreaded members suitably carried by the frame with their pointed ends arranged to engage the floor.
