Abstract

Mouthpiece (1) for wind instruments with a peg-shaped plug connection (2) which is provided with annular grooves (3), in which it is proposed that at least one notch (4) is provided in the groove flank of a groove (3). Due to the notches (4) integrated in the plug connection (2), an exact alignment, positioning and stabilization in the clamping device for milling can be ensured when clamping the mouthpiece (1). There is no need for time-consuming and error-prone adjustment or additional alignment of the mouthpiece (1). Since forces act on the mouthpiece (1) during the milling process, a better pressure distribution can be achieved through the notches (4). Possible natural vibrations of the mouthpiece (1) can thus be better absorbed.

Technical description MAXTON mouthpiece positioning aid

The invention relates to notches as positioning aids for plug-in connections of a woodwind instrument.

State of the art:

The complete clarinet consists of an instrument (funnel, lower part, upper part, barrel), mouthpiece and reed. The mouthpiece is hermetically sealed in the barrel by means of a plug connection. For this purpose, a utility model was submitted in 2004 with the title “Device for the blow pressure-tight closing of plug connections of a woodwind instrument”. Gebrm. No .: 007 141; Record number: GM 0438/2003; Protection begins: 08/15/2004; Class: G10D 007/02; Maximum duration: 30.06.2013 Expired due to the maximum duration being reached.

A so-called "path curve" is milled onto the blank of the mouthpiece. An essential characteristic is the precision with which the trajectory is milled onto the mouthpiece, which is crucial for the sound quality, and thus for the mouthpiece quality. Measurements have shown that when the trajectory is milled, the non-identical positioning of the mouthpieces in the clamping device leads to considerable irregularities at the tip of the mouthpiece, slight slipping during milling, and regular inaccuracies in the range of hundredths of a millimeter as a result of natural vibrations.

Description:

As can be seen from FIG. 1, there are notches (4) in the grooves (3) of the plug connection (2) of the mouthpiece (1) as positioning aids. There are a total of three grooves (3) in the plug connection (2), each with two notches (4), thus a total of six notches (4). The location was chosen so that a notch (4) is always mirrored in position and shape.

Figure 2 shows the notch (4) in detail. The notch (4) in the groove (3) of the plug connection (2) as a positioning aid consists of two side walls (5) and a bevelled surface (6). The notch (4) is conical from the outside in.

The invention to be patented prevents the inaccuracies mentioned in the prior art.

Due to the notches (4) integrated in the plug connection (2), an exact alignment, positioning and stabilization in the clamping device for milling can be ensured when clamping the mouthpiece (1). There is no need for time-consuming and error-prone adjustment or additional alignment of the mouthpiece (1). Since forces act on the mouthpiece (1) during the milling process, a better pressure distribution can be achieved through the notches (4). Possible natural vibrations of the mouthpiece (1) can thus be better absorbed.

With this novelty, unprecedented precision and the resulting quality can be achieved simply and easily. For the first time, the milling process is simpler, cheaper and more efficient. The notches (4) thus lead to a significant increase in the quality of the mouthpieces (1). The sound is also more guided, more stable, clearer, more direct and full - qualities that are appreciated by all clarinettists, regardless of nationality and playing style. This is essential for the economic exploitation of the product.

Claims (3)

508002899 5.9 88 A 60164/2018 Claims: 1. mouthpiece (1) for wind instruments with a pin-shaped plug connection (2) which is provided with annular grooves (3), characterized in that at least one notch (4) is provided in the groove flank of a groove (3). 2. Mouthpiece (1) according to claim 1, characterized in that each of the annular grooves (3) is provided with two notches (4) which are arranged diametrically opposite in the annular groove (3). 3. Mouthpiece (1) according to claim 1 or 2, characterized in that each of the notches (4) is formed from two side walls (6) and a beveled surface (6), the beveled surface (6) of the notch (4) runs conically from the outside to the inside.
