Description

Durch das Patent 82964o ist eine Anordnung an 'remperaturr.cglern elektrisch beheizter Geräte bekanntgeworden, bei der die bei Temperaturänderung eintretende Bewegung des Regelorgans durch eine in ihrer wirksamen Länge zum Zweck der Einstellung des Reglers verstellbare Schubstange auf die Kontakteinrichtung übertragen wird. Erfindungsgemäß erfolgt die Änderung der wirksamen Schubstangeulänge durch einen zwischen Schubstange und Regelargan angeordneten Doppelexzenterbolzen. der mit seinem schwächeren Mittelteil in einem Ausschnitt des freien Schubstangenendes drehbar gelagert, durch seine stärkeren Enden gegen seitliches Ausweichen gesichert und mittels einer Kleinnischraube in beliebiger Lage feststellbar ist.By the patent 82964o is an arrangement of 'temperature control regulators electrically heated devices became known in which the temperature change occurring movement of the regulating organ by one in its effective length for the purpose the setting of the regulator adjustable push rod on the contact device is transmitted. According to the invention, the effective length of the push rod is changed by a double eccentric bolt arranged between the push rod and the control element. the one with its weaker middle part in a cutout of the free end of the push rod rotatably mounted, secured against sideways evasion by its stronger ends and can be locked in any position by means of a small screw.

Dabei wird der Ausschnitt des freien Schubstangenendes zweckmäßig vor dem Lagur des Exzenterbolzens so erweitert, daß dieser senkrecht zur Schubstange eingeführt werden kann.' Die Klemmschraube für den Exzenterbolzen wird von, einem hajonettartig mit dem freien Schubstangenende verbundenen und durch Riegelwirkung gesicherten Bügel gehalten.The cutout of the free end of the push rod is useful in front of the lagur of the eccentric bolt so that it is perpendicular to the push rod can be introduced. ' The clamping screw for the eccentric bolt is from, a hayonet-like connected to the free end of the push rod and by a locking effect secured bracket held.

Die Feineinstellung dieses Temperaturreglers kann somit in 'einfacher Weise durch Drehung des 1-,lxzenterbolzens vorgenommen werden. Da die Äiiderung der wirksamen Schubstangenlänge dabei völlig stufenlos verläuft, ist eine genaue Einstellung des Reglers möglich. Der von dem Exzenterbolzenlager erweiterte Schubstangenausschnitt zur senkrechten Einführung des Exzentorbolzeris in die Schubstange und der bajon#ettartig mit dem freien 'Schubstangenende verbundene Bügel zur Aufnahme der Klemmschraube gewährleisten einen mühelosen Zusammenbau der Einstelleinrichtung.The fine adjustment of this temperature regulator can thus be carried out in a simple manner by turning the 1, lxzenterbolzens. Since the change in the effective length of the push rod is completely stepless, the controller can be set precisely. The extended from the Exzenterbolzenlager push rod extension section to the vertical introduction of the Exzentorbolzeris in the push rod and the bajon # ettartig connected to the free 'push rod end bracket for receiving the clamping screw to ensure an effortless assembly of the adjustment means.

In den Bildern ist eine der möglichen Ausführungsformen dargestellt.One of the possible embodiments is shown in the pictures.

Bild i zeigt einen Teniperatutiregler für elektrisch beheizte Geräte, bei dem das Regielorgan i durch eine Schubstange 2 über den festen Bolzen 3 und den drehbar gelagerten DoppelexzenterbOlzen 4 mit (Icin Kontaktliebel 5 in Verbindung steht. Dabei stützt sich der Doppelexzenterbolzen 4 mit seinen stärkeren Enden an dem Regelorgan i ab und überträgt die bei seiner Drehung eintretende Längenändcrung der Sclitil)st#l"ge 3 auf den Kontakthebel 5. Durch die großeii Längen.unterschiede liel)eldrehpunl<t-Kontal#t wid Hebeldrehpunkt-Angriffspunkt der Schubstange ist eine so große Übersetzung vorhanden. dall bereits bei geringer Drehung des Doppelexzeuterbolzens4 eine g.oß,c Verstellung des Kontaktes 7 gegenüber dem Kontakt 6 eintritt. Nach erfolgter Einstellung wird der Doppelexzenterbolzen 4 mit der Klemmschraube 8 festgestellt, die dann durcli die -Mutter 9 gegen Lockerung gesichert wird. Zur Aufnahme der Klemmschraube8 dient dabei der U-förrnige Bügel io, der mit dein freien Schubstangenende bajonettartig in Eingriff kommt. 111 Bild 2 ist die Schuhstange 2 mit dem Exzenterbolzen 4 und der Klemmschraube 8 in vergrößertem -Maßstab dargestellt.Image i shows communicates a Teniperatutiregler for electrically heated appliances, wherein the Regielorgan i by a push rod 2 via the fixed pin 3 and the rotatably mounted DoppelexzenterbOlzen 4 (Icin Kontaktliebel. 5 Here, the Doppelexzenterbolzen 4 is supported with its stronger ends to the control element i and transmits the change in length of the shaft 3 that occurs during its rotation to the contact lever 5. Due to the large differences in length, the pivot point contact with the lever pivot point of application of the push rod is such Large gear ratio available, so that even with a slight rotation of the double eccentric bolt 4 there is an adjustment of the contact 7 with respect to the contact 6. After the setting has been made, the double eccentric bolt 4 is fixed with the clamping screw 8 , which is then secured by the nut 9 against loosening The U-shaped bracket io, the one with your free push rod, serves to hold the clamping screw8 de comes into engagement like a bayonet. 111 Fig. 2 shows the shoe bar 2 with the eccentric bolt 4 and the clamping screw 8 on an enlarged scale.
