Abstract
The invention provides a pad fitting device for a wind musical instrument key. In this device, the center of the pad (2) is connected to the center of the bottom of the cup (3) by a spherical hinge (5, 6) allowing a free universal angular movement of pad (2) without rotation, so that the pad may assume any slanted position with respect to the cup (3) so as to be applied freely and uniformly at all points of the chimney (1) which it is to close, thus ensuring sealing even in the case of deformation of the key or of the pad (2). Furthermore, since the pad (2) is resiliently snap fitted, it may be replaced instantaneously.
Claims10
A device for fitting a pad actuated by the key of a wind musical instrument so as to close a chimney of said intrument, said device including:
- a cup operationally connectable to said key,
- a pad, made from a compressable material such as flat, fixed to a rigid backing plate,
- a rivet serving as central support for the pad, and
- a hinge with male and female components connecting the center of the pad to the center of the bottom of the cup, so that the pad may assume, through a universal angular free movement, any slanted position with respect to the cup, characterized in that it includes means provided for preventing relative rotation of the pad with respect to the cup.
