Abstract
The invention relates to a wind instrument, for instance, a saxophone or flute. The invention is based on the discovery that a wind instrument, for instance of copper or brass, can be markedly improved by at least one chemically applied coating of hard material. Such a coating applied to the inner side of the tube improves the sound. A coating of phosphor-nickel, preferably with PTFE, applied to the outer side of the instrument has an exceptionally attractive appearance and is less susceptible to scratching. If a coating is applied in swivel bearings of the valve mechanism, disturbing mechanical sounds are reduced and the mechanism moves with less resistance.
Claims10
Wind instrument, comprising a tube provided with holes, characterized by at least one chemically applied coating of hard material.
Wind instrument as claimed in any of the foregoing claims, characterized in that the tube comprises on its outer side at least one coating of phosphor-nickel, preferably phosphor-nickel with PTFE.
Wind instrument comprising a tube, holes of which are provided with valves pivotable on bearings, characterized in that at least one bearing surface, but preferably both mutually facing bearing surfaces of a bearing of a pivotable valve are provided with at least one coating reducing friction and/or wear, for instance of nickel applied without current and preferably a coating of nickel-phosphor with PTFE applied without current to this nickel coating.
Wind instrument as claimed in any of the foregoing claims, characterized in that in the case of a plurality of layers the coating has a thickness in total of a minimum of 7 μm and a maximum of 20 μm.
Wind instrument as claimed in any of the foregoing claims, characterized in that a number of valves (5) each comprise a stiff plate (26) which is provided on the side directed toward the opening (24) with a sealing layer (18) and which on the other side supports via a hard elastic cushion (92) against a support member (94) of control means (9) and is fixed to this support member (94) by means of a flexible fixing member (9).
Wind instrument as claimed in any of the foregoing claims, characterized in that a support member (94) mounted on a valve control arm (9) has a smaller diameter than the associated opening (24).
