<p>PROBLEM TO BE SOLVED: To provide a footrest, which can be simply fixed to an existing chair if necessary, and whose height is alterable to any height. SOLUTION: This footrest 1 is composed of a metal plate 3, which is bent processed, two metal bars 5 and 7 fixed to the metal plate 3 by screws, and rubber sheets 9 and 11 respectively adhered to the back face of the metal bar 5 and the front face of the metal bar 7. The footrest 1 is attached to the legs 22 of a chair 20 for piano playing so that the legs 22 are inserted between the metal bars 5 and 7. When a piano player sitting on a chair 20 rests his or her foot or feet on the metal plate 3 in this condition, force to incline the whole footrest forward is applied on. As a result, the both back and front faces of the metal bar 5 and 7 respectively press the legs 22 stronger from the front and back through the rubber sheets 9 and 11 to make the footrest 1 not to be dropped off from the legs 22.</p> |
