Abstract

The double-spring locking system proposed is intended for the infinitely variable locking of tubes, rods or shafts which rotate, slide or move in some other way. The function of releasing the locking is provided by corresponding mechanisms which take effect via kinks at the ends of the spring. In the double spring, two turns lie axially one above the other, the said turns being interconnected or divided at one end of the spring. A distance between the kinks in the spring permits delayed relaxation of the spring prestress.

Description

Doppelfeder - BlockiersystemDouble spring locking system

Die Erfindung betrifft eine Doppelfeder in Verbindung mit Lösemechanismen nach dem Oberbegriff des Anspruches 1.The invention relates to a double spring in connection with release mechanisms according to the preamble of claim 1.

Die Doppelfeder wird durch zwei Federn gebildet,die mit ihren Wicklungen übereinander liegen und aus einen Draht gedreht sind Die Endabknickungen werden durch exial-oder seitlich abgewinkelte Drahtverlängerungon dargestellt, deren zwei zusammenliegende ungeteilt sein können.The double spring is formed by two springs with their windings lie on top of each other and are twisted from a wire represented by exial or laterally angled wire extensions, two of which together can be undivided.

Die abgeknickten Drahtenden sind einmal zur Festlegung des einen Federendes in einem Gehäuse ,Ring o.ä. , desweiteren zum Ansetzen des Lösemechanismus am entgegengesetzten Federende notwendig.The kinked wire ends are used to fix one end of the spring in a housing, ring or the like, furthermore for attaching the release mechanism to the opposite one End of spring necessary.

Die Federn sind vorgespannt,weisen also einen geringeren Querschnitt auf als das Gestänge oder Rohr bezw.dis Welle'die sie koaxial umschließen.Die Vorspannung der Federn bewirkt, daß das umschlossene material axial- wie auch in Richtung der Foderwicklung blockiert wird,so z.B.The springs are pretensioned, so they have a smaller cross-section on as the rod or pipe or the shaft, which they coaxially enclose the springs causes the enclosed material axially as well as in the direction of the Feed development is blocked, e.g.

bei drehenden tIIellon.Verstellbar wird die Vorspannung dadurch,daß zwei nebeneinander liegende Endabknickungen in einer Nut eines um die Längsachse der Feder drehbaren Ringes liegt.Durch Drehung des Ringes wird die Vorspannung wahlweise rhöht- oder verringert Der Ring ist feststellbar.Ein Beispiel zeigt die Zeichnung mit Figur 6.with rotating tIIellon.Adjustable is the preload that two adjacent end bends in a groove one around the longitudinal axis the spring rotatable ring. By rotating the ring, the preload is optional Increased or decreased The ring can be locked. The drawing shows an example with figure 6.

Die Anwendungsgebiete des Doppelfeder-Blockiorsystems sind unübersichtlich Das System ist überall dort anwendbar'wo es um die Bockierung mit Lösemöglichkeit von Wellen, Rohren etc. geht, aber auch zur Drehzahlminderung rotierender Wellen etc. Das Blockiersystem kann u.a. anwendbar sein als Alternative zu Verschraubungen oder ähnlichen Fest- tellungen,wie sie in der Technik häufig vorkommen, wobei weitgehende Wartungafreiheit des Systems als vorX teilhaft erscheint.The areas of application of the double spring blocking system are confusing The system can be used wherever there is a need for a lock with the possibility of releasing it of shafts, pipes, etc., but also to reduce the speed of rotating shafts etc. The blocking system can, among other things, be used as an alternative to screw connections or similar festival settings as they often occur in technology, where the system is largely maintenance-free appears to be advantageous.

Die Verzögerung des Löse-Vorgange wird durch den Abstand der Endabknickungen (1) und (2) erreicht dadurch,das die Feder (2) gelöst wird durch Anschlag der Feder (1),die vor der Feder (2) gelöst wird.Die Feder (2) liegt also noch an.The delay in the release process is determined by the distance between the end bends (1) and (2) achieved in that the spring (2) is released by stopping the spring (1), which is loosened before the spring (2), which means that the spring (2) is still in contact.

Wird der Federaufbau so gestaltet, wie auf der Zeichnung mit Fig. 1 ersichtlich, also mit ungeteilter Feder (3),ist beim Lösen der Federn zu (3) ein konischer Effekt erreicht, der auf den Lösevorgang verzögernd wirkt.If the spring structure is designed as shown in the drawing with Fig. 1, i.e. with an undivided spring (3), is on when the springs for (3) are loosened A conical effect is achieved, which has a delaying effect on the release process.

Verzögerung bezw Dämpfung in beschriebener Form ist durch eine einfache Zylinderschraubenfeder nicht erreichbar.Delay or attenuation in the form described is simple Cylinder coil spring cannot be reached.

Die Lösemechanismen werden zweckmäßig den jeweiligen Anwendungsgebieten angepaEt,wie aus den Zeichnungen mit den Figuren 2- bis 8 beispielhaft ersichtlich ist.Sie stellen wesentlich keine Neuheiten dar,auch Bowdenzüge'Elektromagnete etc.erscheinen verwendbar zwecks Federnlösung.The release mechanisms are appropriate to the respective areas of application adapted, as can be seen by way of example from the drawings with FIGS. 2-8 They are essentially nothing new, Bowden cables, solenoids etc. also appear usable for the purpose of spring solution.
