Description
Zugfederbefestigung. Die Befestigung von Zugfedern ist insofern schwierig, als die haken- oder ösenartig gelogenen Federenden leicht schlapp werden oder abbrechen, cla sie zum Biegen enthärtet «-erden müssen. Ferner entstehen bekanntlich immer an der Übergangsstelle vom harten zum ausgeglühten Teil des Drahtes erhebliche Spannungen, die meist ein vorzeitiges Brechen an dieser Stelle verursachen.Tension spring fastening. The attachment of tension springs is difficult to the extent that when the hook-like or loop-like spring ends are easily slack or break off, cla them to be softened «-grounded for bending. Furthermore, as is well known, always arise Considerable stresses at the transition point from the hard to the annealed part of the wire, which usually cause premature breakage at this point.
Bei einer bekannten Befestigungsvorrichtung kommen Schrauben zur Anwendung, die.. bei Zugbeanspruchungen der L# e(ler keinen sicheren Halt gewähren : denn durch die stoßweisen Belastungen werden sie schnell gelockert und gelöst. Außerdem muß auch -hierder Federdraht erst entsprechend gebogen werden, um an der Platte befestigt werden zu können. Diese Befestigungsvorrichtung ist also nur für Druckfedern geeignet. E=inein anderen bekannten Befestigungsmittel haften die erwähnten Mängel nicht an, denn (las Federendo ist auf einen Gewindekern geschraubt, der Haken oder f-)sen trägt. Dieses Mittel ist aber sehr teuer und außerdem immer nur für eine ganz bestimmte E# edergröße passend. Denn wenn die Drahtivindungen sich nicht genau in die Windungen des Kernes einlegen, (lann sitzt dieser nicht genügend fest. Solche Befestigungen müssen z.lso für jede vorkommende Federgröße (hinsichtlich Windungsdurchinesseund Draht-# iiti stärke# -eirri gehalten werden. Dadurch wird dieses Befestigungsmittel so teuer, claß es Sich nicht allgemein eing; fü hrt hat.In a known fastening device, screws are used, the .. with tensile stresses on the L # e (ler do not provide a secure hold: because through the intermittent loads are quickly loosened and released. Also must also - here the spring wire must first be bent accordingly in order to be attached to the plate to be able to. This fastening device is therefore only suitable for compression springs. E = the defects mentioned do not adhere to any other known fastening means, because (las Federendo is screwed onto a thread core, the hook or f-) sen wearing. However, this remedy is very expensive and, moreover, only ever for a very specific one E # eder size suitable. Because if the wire connections are not exactly in the turns insert the core, (then it does not sit firmly enough. Such fastenings must e.g. for each occurring spring size (with regard to winding diameter and Wire- # iiti strength # -eirri be held. This will make this fastener so expensive, it was not generally accepted; has led.
Der Erfindungsgegenstand ist in jeder Hin-.>icht einfacher, billiger und zuverlässiger Die Drahtenden bleiben unverändert, die An. bringung ist schnell und einfach geschehen der Halter besteht nur aus einem einfachen leicht herzustellenden Stück, und eine Haltergröße paßt für mehrere Federgrößen.The subject of the invention is in every respect - not simpler, cheaper and more reliable The wire ends remain unchanged, the An. delivery is quick and easy to do the holder consists of just a simple, easy-to-manufacture one Piece, and one holder size fits several nib sizes.
Die neue Zugfederbefestigung besteht aus einer mit Haken und Öse versehenen Platte, die zum Einschieben des Drahtendes niehrerc Löcher und einen am inneren Ende abgebogenen Lappen zum Stützen der Platte besitzt.The new tension spring attachment consists of a hook and eye Plate with holes for inserting the wire end and one on the inside Has bent end tabs to support the plate.
Die Zeichnung veranschaulicht in den Abb. 1, 2 und 3 mehrere Ansichten der Zugiederbefestigung.The drawing illustrates several views in FIGS. 1, 2 and 3 the attachment.
Eine Platte a ist mit zwei oder mehreren. den Federwindungen entsprechend versetzten Löchern b und einem Haken d oder einer Üse f versehen. Der untere Rand neben den Löchern b ist in Form von Lappen g nach leiden Seiten umgebogen und zugeschärft. Derart gestaltet--- Platten werden auf den Federenden befestigt, indem das Drahtende durch die Löcher b geschoben wird. Die Lappen- dienen zunächst dazu, die Drahtenden al-zulieben und die Platte zu stützen.A plate a is with two or more. according to the spring coils offset holes b and a hook d or a Üse f provided. The lower edge next to the holes b is bent over and sharpened in the form of lobes g to suffer sides. So Shaped --- Plates are attached to the spring ends by the wire end is pushed through the holes b. The tabs are initially used to hold the wire ends al-zulieb and to support the plate.
