Description
Dichtsch &bgr; i b e Dichtsch &bgr; ibe
Die Neuerung bezieht sich auf eine Dichtscheibe, die an bekanntenThe innovation relates to a sealing disc that is used on known
%' Holz- und Blechblasinstrumenten eine entsprechende Öffnung abdichtet. %' woodwind and brass instruments seals a corresponding opening.
Zur Dichtung entsprechender Öffnungen an Holz- und Blechblas- i. instrumenten werden unter den Metallklappen sogenannte Polster verwendet. Sie bestehen aus einem feuchtigkeitsunemafindlichen, H uieichen Material. Die Befestigung an den Metallklappen geschieht durch kleben oder druckknopfahnlichem Verschluß.To seal the corresponding openings on woodwind and brass instruments, so-called pads are used under the metal flaps. They are made of a moisture-resistant, soft material. They are attached to the metal flaps by gluing or using a snap fastener.
Die Funktion oder das sog. "Ansprechen" eines Blasinstrumentes hängt weitgehend von der Dichtheit dieser Klappen ab.The function or so-called "response" of a wind instrument depends largely on the tightness of these valves.
In der Praxis gibt es öfters Probleme mit diesen Polstern. Die dem Klappendrehpunkt zugewandte Dichtfläche iuird zuerst vom Polster berührt, erst durch komprimieren des Polsters dichtet die gesamte Fläche. Durch ständiges Anpressen des Polsters tritt eine bleibende Verformung ein. Das Polster wird hart, die Dichtfunktion läßt nach.In practice, there are often problems with these pads. The sealing surface facing the flap pivot point is first touched by the pad, and only when the pad is compressed does the entire surface seal. Constant pressure on the pad causes permanent deformation. The pad becomes hard and the sealing function deteriorates.
Ein weiterer Machteil bekannter Polster besteht darin, daß bei Erstmontage und Reparaturen die Metallklappen genau angepaßt und bsi Reparaturen demon-1 -iert o/erden müssen. Dies ist ein erheblicher Zeitaufwand.Another disadvantage of known cushions is that during initial assembly and repairs the metal flaps have to be precisely adjusted and dismantled until repairs are carried out. This is a considerable time-consuming process.
Die Neuerung dient dem Zwack, diese Mangel zu beheben» An den bekannten Klappen, die zur Aufnahme der Dichtpolster dienen, ist eine topfartige, runde Aussparung 1 . In diaser Aussparung sind die 3 sternförmig angeordneten Rastnocken 2 vsrrastet. Diese Art der Verrastung gibt der Dichtscheibe einen guter. Halt in der Metallklappe. Ein Auswechseln dieser Dichtsühöibe ist ohne Demontage der Klappe« auszuführen.The innovation serves the purpose of remedying this deficiency. The known flaps, which serve to accommodate the sealing pads, have a pot-shaped, round recess 1. The three star-shaped locking cams 2 are locked into this recess. This type of locking gives the sealing disc a good hold in the metal flap. This sealing disc can be replaced without dismantling the flap.

Ein umitörer Vorteil Hegt darin» daß zwischen den Rastnocken und der Dichtscheibe ,5 ein dünner Stec) 3 einen Luftspalt bildet. Dieser Luftspalt ermöglicht, Toleranzen zwischen dem ftlappentopf und der Dichtebene ieicht auszugleichen. ZeitaUf^ luendiges Anpassen der Klappen entfallt» Die Funktion der Dichtung ist deshalb gewährleistet, u/eil die Auspfesskra'fte zentral in die Dichtfläche 5 eingeleitet luerden. Zur optimalen Dichtheit und zur Geräuschminderung ist die leicht geiüölbte Unterseite der Oishtfläehe 5 mit einem v/erhauteteri WeichschäUm &', versehen»A further advantage is that a thin piece of wood 3 forms an air gap between the locking cams and the sealing disc 5. This air gap makes it easy to compensate for tolerances between the flap pot and the sealing plane. Time-consuming adjustment of the flaps is no longer necessary. The function of the seal is therefore guaranteed because the ejection forces are introduced centrally into the sealing surface 5. For optimum sealing and to reduce noise, the slightly curved underside of the sealing surface 5 is provided with a skin-covered soft foam 6 .
