Abstract: The invention concerns a lip element for instrument with single flapping reed for instance for clarinet or saxophone, comprising mouthpiece (10), a reed (12) and a ligature for fixing the reed (12) to the mouthpiece (10). In said (14) is interposed between the reed (12) and the mouthpiece (10), thereby modifying the conditions in which the two each other, and in particular enabling to optimize the vibrational behavior of the reed (12), by virtually modifying the table of the mouthpiece (10). The insert consists of a thin plastic or metal film provided with an adhesive and has a bevelled profile.

In said mouthpiece, an insert (14) is interposed between the reed (12) and the mouthpiece (10), thereby modifying the conditions in which the two co-operate with each other, and in particular enabling to optimize the vibrational behaviour of the reed (12), by virtually modifying the table of the mouthpiece (10). The insert consists of a thin plastic or metal film provided with an adhesive and has a bevelled profile.

Abstract: A folding and height adjustable assembly for supporting or transporting an individual or a child includes a bearing or rolling structure with two beams and a structure for carrying a support for the individual or child. The carrying structure can be hinged at its base and can occupy a storage position wherein uprights are substantially parallel to the beams, and an operating position wherein the uprights form an acute angle with respect to the beams. The support for the person is fixed between two branches of a guiding handle. A height locking mechanism is located between at least one upright of the carrying structure and a branch of the guiding handle and locks the branch in at least two predetermined positions.
