Description
Die Erfindung bezieht sich auf ein Verformungselement,
welches aus zwei miteinander verbundenen Materialstrei
fen mit unterschiedlichen Dehnungskoeffizienten gebildet
ist und eine elektrische Heizung zum Erwärmen und damit
Verformen des Verformungselementes aufweist. Solche Ver
formungselemente sind in Bimetallschaltern vorgesehen
und allgemein bekannt.
Bei den bekannten Bimetallschaltern wird die bei Erwär
mung des Verformungselementes auftretende Bewegung für
schalttechnische Zwecke genutzt, beispielsweise bei
einem Thermostat. Die zusätzliche Heizung, welche aus
einer um das Verformungselement geschlungenen Heizwick
lung besteht, führt zu einem nicht auf Magnetisierung
beruhenden elektro-mechanischen Schalter.
Nachteilig bei den bekannten Schaltern ist es, daß sie
durch die Anordnung der Heizung relativ aufwendig werden
und deshalb teuer in der Herstellung sind. Da es sich
bei solchen Verformungselementen und den aus ihnen
gebildeten Schaltern jedoch meist um Massenartikel
handelt, ist es wünschenswert, wenn diese so einfach wie
möglich ausgebildet sind, damit sie kostengünstig herge
stellt werden können.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfor
mungselement der eingangs genannten Art derart auszu
bilden, daß es möglichst einfach aufgebaut und dadurch
kostengünstig herstellbar ist.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß
die elektrische Heizung ein fest mit dem Verformungs
element verbundenes Folienheizelement ist.
Solche Folienheizelemente werden für andere Zwecke in
großen Stückzahlen verwendet und sind deshalb kosten
günstig erhältlich. Sie bestehen aus einer Kunststoff
folie, welche einseitig dünn metallisiert und als Schutz
oder Isolierung wieder mit einer Kunststoffolie über
zogen ist. Die Metallisierung kann durch Bedampfen, Be
sputtern oder Auflaminieren einer Metallfolie erfolgen.
Die Metallschicht des Folienheizelementes kann, muß aber
nicht, strukturiert sein.
Das erfindungsgemäße Verformungselement ist sehr kosten
günstig herstellbar und sieht aus wie ein übliches Bime
tallelement. Es nimmt auch nicht mehr Platz ein als ein
solches Bimetallelement, so daß es wesentlich kompakter
ist als übliche Dehnungselemente mit einer elektrischen
Heizung.
Ganz besonders günstig ist es, wenn das Folienheizele
ment zwischen den beiden Materialstreifen vorgesehen
ist, da es dort vor mechanischer Beschädigung geschützt
ist.
Eine alternative Ausführungsform besteht darin, daß das
Folienheizelement auf einem der Materialstreifen vor
gesehen ist. Denkbar ist hierbei, daß das Folienheiz
element entweder auf einer der Außenseiten des Dehnungs
streifens oder aber auf einer vorspringenden Fläche
eines Materialstreifens angeordnet wird, auf der weiter
hinten der andere Materialstreifen angeordnet ist.
Das Folienheizelement ist sehr einfach mit den Material
streifen verbunden, wenn es auf oder zwischen die Mate
rialstreifen geklebt ist.
Das Verbinden der Materialstreifen und des Folienheiz
elementes miteinander ist ganz besonders einfach, wenn
die Materialstreifen aus einem Kunststoff mit unter
schiedlichem Dehnungskoeffizienten bestehen.
Ebenfalls sind die Materialstreifen und das Folienheiz
element sehr einfach miteinander verbunden, wenn gemäß
einer anderen Ausgestaltung der Erfindung die Material
streifen unter Einschluß des Folienheizelementes mit
einander verschweißt sind.
Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur
weiteren Verdeutlichung ihres Grundprinzips sind drei
davon in der Zeichnung dargestellt und werden nachfol
gend beschrieben. Die Zeichnung zeigt in
Fig. 1 eine perspektivische Darstellung einer
ersten Ausführungsform eines erfindungsge
mäßen Dehnungselementes,
Fig. 2 eine perspektivische Darstellung einer
zweiten Ausführungsform eines erfindungsge
mäßen Dehnungselementes,
Fig. 3 eine perspektivische Darstellung einer
dritten Ausführungsform eines erfindungsge
mäßen Dehnungselementes.
Die drei Figuren zeigen jeweils Dehnungselemente, welche
aus zwei aufeinanderliegenden Materialstreifen 1, 2 und
einem Folienheizelement 3 aufgebaut sind. Das Folien
heizelement 3 kann von üblicher Bauart und zum Anschluß
zweier elektrischer Leiter 4, 5 ausgebildet sein. Bei
der Ausführungsform gemäß Fig. 1 ist das Folienheiz
element 3 zwischen die Materialstreifen 1, 2 geklebt.
Gemäß Fig. 2 befindet es sich oben auf dem oberen
Materialstreifen 1.
Bei der Ausführungsform gemäß Fig. 3 ist der untere
Materialstreifen 2 breiter als der obere Materialstrei
fen. Dadurch entsteht eine vorspringende Fläche 6, auf
der das Folienheizelement 3 aufgebracht ist.
