Description

Schraubenfeder. Die Erfindung betrifft eine Schraubenfeder aus: Draht beliebigen Querschnitts, die sich durch verschiedene Weite :oder Größe der Windungen kennzeichnet.Coil spring. The invention relates to a helical spring made from: wire any cross-section, which is different in width: or size of the turns indicates.

Es sind zylindrische Schraubenfedern bekannt, bei: denen zylindrische Windungen verschiedener Weite oder Größe ineinanderliegen, die äußere und inne xe Windung ,aber von gleichbleibender Weite bzw. Größe sind. Ferner sind kugelige Schraubenfedern in ähnlicher Weise bekannt, nur daß bei diesem. die Weite der äußeren und inneren Windungen nach einem Endre kleiner wird. Es Sind also gewissermaßen zwei zylindrische oder kegelige Schraubenfedem von verschiedener Windungsweite ineinandergesteckt.Cylindrical coil springs are known in which: which are cylindrical Windings of different widths or sizes lie one inside the other, the outer and inner xe Winding, but of constant width or size. Furthermore, there are spherical coil springs known in a similar way, only that with this one. the expanse of the outer and inner Turns becomes smaller after an end. So there are, so to speak, two cylindrical ones or conical coil springs with different winding widths plugged into one another.

Den bekannten Schraubenfedern gegenüber unterscheidet sich der Gegenstand der Erfindung dadurch, daß größere oder weitere Windungen mit kleineren oder engeren in exzentrischer Lage in steter Aufeinanderfolge abwechseln, so daß die kleineren. oder engeren Windungen. an einer Stelle des Umfanges um etwa Drahtdicke gegen die größeren oder weiteren Windungen zurückliegen, während sie an der gegenüberliegenden Stelle des Umfanges mit den größeren oder weiteren Windungen in gleicher Ebene liegen.The subject differs from the known coil springs of the invention in that larger or more turns with smaller or narrower alternate in an eccentric position in constant succession, so that the smaller. or tighter turns. at one point on the circumference by about wire thickness against the larger or further turns are behind while they are on the opposite Place of the circumference with the larger or further turns are in the same plane.

Die Zeichnung zeigt ein Ausführungsbeispiel der Feder in Abb. i und z.The drawing shows an embodiment of the spring in Fig. I and z.

Die Feder ist mit verschieden weiten oder großen Windungen rx und b ausgeführt, derart, daß die Windungen ,a größeren Durchmesser oder größere Weite haben als die Windungen b. Nach der Zeichnung beträgt der Unterschied der Durchmesser oder Größe der Windungen etwa Drahtdicke. Der Unterschied kann aber auch ein anderer sein. Statt aus Runddraht, wie gezeichnet, kann die Feder auch aus Draht von anderem Querschnitt sein.The spring is designed with different wide or large turns rx and b , such that the turns a have a larger diameter or greater width than the turns b. According to the drawing, the difference in the diameter or size of the turns is about wire thickness. But the difference can also be different. Instead of round wire, as shown, the spring can also be made of wire with a different cross-section.

Die Feder ist hauptsächlich für den Gebrauch in 'gekrümmter Form nach A,bb. z bestimmt und hat den wesentlichen Vorteil, daß die kleineren oder engeren Windungen b sich innen zwischen die größeren :oder weiteren Windungen legen und die Windungen außen nicht so weit auseinanderliegen wie bei Federn mit gleich großen oder weiten Windungen.. Die Feder ist daher viel widerstandsfähiger in guter Verwendung als die bekannten.The spring is mainly designed for use in 'curved shape' A, bb. z determines and has the major advantage that the smaller or narrower Windings b are placed inside between the larger: or further windings and the coils on the outside are not as far apart as in springs of the same size or wide coils .. The spring is therefore much more resistant when used well than the known.

PATENT-ANSpRUcH: Schraubenfeder aus Draht beliebigen Querschnitts mit Windungen verschiedener Weite oder Größe, dadurch gekennzeichnet, daß größere oder weitere Windungen mit kleineren :oderengeren Windungen in exzentrischer Lage zu ersteren in steter Aufeinanderfolge abwechseln, so daß die kleineren oder engeren Windun-.gen an :einer Stelle des Umfanges um etwa Drahtdicke gegen die größeren oder weiteren Windungen zurückliegen, während sie an der gegenüberliegenden Stelle des Umfanges mit den größeren oder weiteren Windungen. in gleicher Ebene liegen. PATENT CLAIM: Helical spring made of wire of any cross-section with turns of different widths or sizes, characterized in that larger or further turns with smaller or smaller turns alternate in an eccentric position with the former in constant succession, so that the smaller or narrower turns : one point of the circumference by about wire thickness behind the larger or further turns, while they are at the opposite point of the circumference with the larger or further turns. lie in the same plane.
