Abstract

A quick-action closure screw system in order significantly to shorten the time-consuming screwing-in process. A system is proposed here which, by means of a variable screw area and variable threaded jaws, ensures that the screw and nut can be pushed over one another without any significant loss of strength. It is always possible to use each part independently as a screw or nut. The advantages which occur in the case of this system are a reduced labour cost, and overtightening of the respective element is also prevented.

Description

Gegenwärtig werden Schraubsysteme (Schraube und zugehö­ rige Mutter) derart ausgeführt, daß beim Einbringen der Schraube ins Muttergewinde der gesamte Schrauben­ gewindeweg zurückgelegt werden muß, was speziell bei langen Schrauben einen erheblichen zeitlichen Aufwand zur Folge hat.Screw systems (screw and associated mother) executed so that when inserting the screw into the nut thread of the entire screw thread must be covered, which is especially for long screws a considerable amount of time has the consequence.

Die hier vorgestellte Erfindung soll, wie im folgenden beschrieben, diesen zeitlichen Aufwand reduzieren.The invention presented here is intended as follows described, reduce this time expenditure.

Ein Ausführungsbeispiel der Erfindung, des Schnellschraubenverschlußsystemes ist in der Zeichnung Blatt 1 dargestellt und wird im folgenden näher be­ schrieben. Es zeigtAn embodiment of the invention, the Quick screw locking system is in the drawing Sheet 1 is shown and will be described in more detail below wrote. It shows

Fig. 1 eine Seitenansicht der Schnellverschluß­ schraube mit spreizbarem Anlaufgewinde 1 und 2 , Leerraum für elastisches Medium 3, Fig. 1 is a side view of the quick-locking screw with spreadable start thread 1 and 2, space for elastic medium 3,

Fig. 2 eine kopfseitige Draufsicht auf die obig­ genannte Schnellverschlußschraube mit gleicher Nummernfolge, Fig. 2 shows a head-side plan view of the above-mentioned quick-locking screw with the same number sequence,

Fig. 3 eine zentrale Draufsicht auf die Schnellver­ schlußmutter 4, Gewindebacken 5, Leer­ raum für elastisches Medium 6, Verschluß der Schnellverschlußmutter 7, Gewindebacken­ halterung 8. Fig. 3 is a central plan view of the Schnellver lock nut 4 , threaded jaws 5 , empty space for elastic medium 6 , closure of the quick-lock nut 7 , threaded jaw holder 8th

Fig. 4 zeigt einen Schnitt durch das System, Schraube- Mutter, bei gleicher Nummerierung. Fig. 4 shows a section through the system, screw-nut, with the same numbering.

Dazu ist ein Schrauben-Basiskörper 1, Fig. 1 mit her­ kömmlichem Schraubenkopf derart mit Gewindesegmenten 2, Fig. 1 umgeben, daß die Gewindesegmente - wie im Ausführungsbeispiel gezeigt, 6 an der Zahl - abspreiz­ bar ausgeführt sind. Die dadurch entstehenden Hohl­ räume 3, Fig. 1 sind mit einem elastischen, deformier­ baren Medium (z. B. Silikon) ausgefüllt, so daß bei Andrücken der Gewindesegmente 2, Fig. 1 eine stetige Kraft in radialer Richtung auf diese wirkt. Dazu zeigt Fig. 2 eine kopfseitige Aufsicht der Schraube. Ein zeitlicher Gewinn beim Einschraubvorgang läßt sich nun dadurch er­ reichen, daß z. B. im Verbund mit einer Schnellverschluß­ mutter, die derart ausgeführt ist, daß ein Mutterbasis­ körper 4, Fig. 3 derart beschaffen ist, daß mehrere Ge­ windebacken 5, Fig. 3 - wie im Ausführungsbeispiel ge­ zeigt 4 - so gelagert sind, daß die Gewindebacken 5, Fig. 3 in radialer Richtung zunächst beweglich gelagert sind und die dadurch entstehenden Hohlräume 6, Fig. 3 mit einem elastischen, deformierbaren Medium gefüllt sind, so daß beim Andrücken der Gewindebacken 5, Fig. 3 an den Mutter­ basiskörper 4, Fig. 3 eine stetige radiale Kraft in Rich­ tung des Zentrums wirkt, womit sich erreichen läßt, daß zwischen den Gewindesegmenten der Schnellverschluß­ schraube 3, Fig. 1 und den Gewindesegmenten der Schnell­ verschlußmutter 5, Fig. 3 ein stetiger gegenseitiger Anpreßdruck herrscht und damit sicheren Halt gewährleistet. For this purpose, a screw base body 1 , FIG. 1 with a conventional screw head is surrounded with thread segments 2 , FIG. 1 such that the thread segments — as shown in the exemplary embodiment, 6 in number — are designed to be spread apart. The resulting cavities 3 , Fig. 1 are filled with an elastic, deformable ble medium (z. B. silicone), so that when pressing the threaded segments 2 , Fig. 1, a constant force acts in the radial direction on this. For this purpose, Fig. 2 is a side plan view of the screw head. A time gain in the screwing process can now be enough that z. B. in combination with a quick release nut, which is designed such that a mother base body 4 , Fig. 3 is such that several Ge threaded jaws 5 , Fig. 3 - as shown in the exemplary embodiment GE 4 - are stored so that the Threaded jaws 5 , Fig. 3 are initially movably mounted in the radial direction and the cavities 6 , Fig. 3 thereby created are filled with an elastic, deformable medium, so that when pressing the threaded jaws 5 , Fig. 3 onto the nut base body 4 , Fig . 3 a continuous radial force in Rich tung the center acts, can be thus achieved that between the thread segments of the quick screw 3, Fig. 1 and the thread segments of the quick release nut 5, Figure 3 prevails. a continuous mutual contact pressure and thus secure support guaranteed.

Der langwierige Einschraubvorgang erübrigt sich insofern, als das Schnellschraubverschlußsystem es ermöglicht, durch ein Übereinanderschieben der Gewindebacken von Mutter und Schraube, die in ra­ dialer Richtung gegeneinander beweglich sind, den zurückzulegenden Gewindeweg zu reduzieren. Betreffs der Schnellverschlußmutter ist noch an­ zumerken, daß die Gewindebacken 5, Fig. 3 allseits eingelagert sind, wie durch 7, Fig. 3 angedeutet und daß je nach Anwendungsgebiet und Festigkeits­ anforderungen die Gewindebackenhalterung 8, Fig. 3 die dazu dienen die Gewindebacken auf dem Umfang örtlich zu fixieren, stärker oder schwächer ausge­ führt sein können.The tedious screwing process is superfluous insofar as the quick screw closure system makes it possible to reduce the thread path to be covered by sliding the threaded jaws of the nut and screw, which are mutually movable in radial direction. As for the quick-lock nut, it should also be noted that the threaded jaws 5 , Fig. 3 are embedded on all sides, as indicated by 7 , Fig. 3 and that, depending on the field of application and strength requirements, the threaded jaw holder 8 , Fig. 3 are used for the threaded jaws on the To fix the scope locally, may be stronger or weaker.

Obig angesprochenes Übereinanderschieben der Gewinde­ backen 2, Fig. 1 und 5, Fig. 3 erfolgt in der Praxis der­ art, daß durch Kraftausübung auf den Schraubenkopf in Richtung der Achse die Schraube zunächst, durch zurückweichen der Gewindebacken 5, Fig. 3 und 2, Fig. 1, in die Schnellverschlußmutter eingeführt wird und durch kurzes Anziehen der Schraube ein optimaler Sitz erreicht wird.The above-mentioned sliding of the thread bake 2 , Fig. 1 and 5 , Fig. 3 takes place in practice in such a way that by exerting force on the screw head in the direction of the axis, the screw first, by retreating the threaded jaws 5 , Fig. 3 and 2 , Fig. 1, is inserted into the quick-release nut and an optimal fit is achieved by briefly tightening the screw.

Fig. 4 zeigt bei gleicher Nummerierung wie Fig. 1 bis 3 einen Schnitt durch das System Schnellver­ schlußschraube-Schnellverschlußmutter. Fig. 4 shows the same numbering as Fig. 1 to 3 a section through the system Schnellver lock screw quick lock nut.

Darüber hinaus bietet sich die Möglichkeit des getrennten Einsatzes von Schnellverschlußschraube und Schnellver­ schlußmutter. Bei getrenntem Einsatz ist jedes Teil für sich als selbstsicherndes System anzusehen.In addition, there is the possibility of separate Use of quick release screw and quick lock closing mother. When used separately, each part is to be viewed as a self-locking system.

Die Konstruktion des Systems schließt desweiteren die Möglichkeit der Zerstörung des Gewindes durch über­ drehen aus, da in einem solchen Falle die Gewinde­ segmente zurückweichen können.The construction of the system also includes Possibility of destroying the thread by over turn out because in such a case the threads segments can retreat.
