Abstract

The clip fastens a hose to a nipple. It consists of a band, the ends of which overlap, when locked. The outer band end has perforations, while the inner end is provided with hooks, to engage in the perforations as in 555024. The lower band end (4) has an upwardly pointing tongue (14). The tongue is guided axially in a slot (9) of the upper band end (2). The clip is readily manipulated into position and gives a reliable fastening of the hose to the nipple. The design is such that sideways displacement of the overlapping portions of the band does not readily occur.

Description

  

  
 



   Die Erfindung betrifft eine Verbesserung der Klemmbride nach dem Hauptpatent, welche mit Mitteln mit oder ohne Werkzeug zum Festklemmen eines Schlauches auf einem Nippel versehen ist, welche Bride aus einem schliessbaren Band besteht, wobei sich in der Schliessstellung die Enden des Bandes überlappen, und wobei Perforationslöcher im äusseren Bandende und Widerhaken am inneren Banc ende vorgesehen sind, die beim Umlegen des Bandes um einen Schlauch in die Perforationslöcher einhaken, und wobei zum Zusammenziehen des Bandes im inneren Bandende ebenfalls Perforationslöcher und im äusseren Bandende über dem Bereich der zweitgenannten Perforationslöcher ein Schlitz vorgesehen ist, wobei dasjenige Ende des Schlitzes im äusseren Bandende, das in Zugrichtung vorne liegt, eine Stauchung nach aussen aufweist.



   Mit Rücksicht auf die Festigkeit der Stege zwischen den Perforationslöchern des oberen Bandendes, in welche der Widerhaken einhakt, weist der Abstand zwischen unmittelbar benachbarten Perforationslöchern in Umfangsrichtung der Klemmbride stets einen Wert von einer gewissen Bedeutung auf; das führt dazu, dass für das Einhaken des Widerhakens in ein Perforationsloch des oberen Bandendes zur Herstellung der erforderlichen Ringspannung unter Umständen ganz erhebliche Kräfte auf die Klemmbride übertragen werden müssen. Dies ist insbesondere dann der Fall, wenn der Schritt zwischen zwei Perforationslöchern gross ist und eine genügende Ringspannung bei Einhaken des Widerhakens in das dem oberen Bandende benachbarte Perforationsloch beinahe erreicht wäre, wobei aber der Widerhaken noch in das nächste Perforationsloch einhaken sollte.

  In solchen Fällen lassen sich die zum Zusammenziehen der Bandenden notwendigen Kräfte bei herkömmlichen Klemmbriden nicht ohne weiteres, das heisst einfach, zeitsparend und sicher auf dieselben übertragen. Mit andern Worten besteht die Gefahr eines Abgleitens beispielsweise einer Spreizzange, wobei der Zusammenziehvorgang öfters neu begonnen werden muss.



  Insbesondere bei dünner Schlauchwand und/oder nicht   beson    ders elasfischem Schlauchmaterial ist es unter Umständen unumgänglich, in das Band der Klemmbride ein Federelement einzubauen, was die Kosten erhöht.



   Die Erfindung macht sich den Fortschritt des Hauptpatents zunutze, welcher darin besteht, dass auch ein einfachstes Zusammenziehinstrument leicht und zuverlässig an der Klemmbride angesetzt werden kann. Überdies soll nun noch eine seitliche gegenseitige Verschiebung der übereinanderliegenden Bandteile verhindert werden können.



   Erfindungsgemäss weist dazu das untere Bandende eine nach oben, das heisst radial nach aussen weisende Zunge auf, welche im Schlitz des oberen Bandendes axial geführt ist. Mit dieser Massnahme wird der Schlauch geschont und eine axiale Deckung der übereinanderliegenden Bandenden gewährleistet.



   In der Zeichnung ist ein Ausführungsbeispiel einer Klemmbride vereinfacht dargestellt. Die einzige Figur zeigt eine axiale Ansicht einer teilweise geschnittenen offenen Klemmbride, wobei die Bezugszeichen 1 bis 10 denjenigen der Zeichnung des Hauptpatents entsprechen.



   Das untere Bandende 4 weist eine radial nach aussen, also nach oben gebogene Zunge 14 auf, welche im Schlitz 9 des oberen Bandendes (2) axial geführt ist. 



  
 



   The invention relates to an improvement of the clamp according to the main patent, which is provided with means with or without a tool for clamping a hose on a nipple, which clamp consists of a closable strap, the ends of the strap overlapping in the closed position, and perforation holes In the outer end of the band and barbs on the inner end of the banc, which hook into the perforation holes when the band is folded around a tube, and perforation holes are also provided in the inner end of the band and a slot is provided in the outer end of the band above the area of the second-mentioned perforation holes , whereby that end of the slot in the outer end of the tape which is at the front in the pulling direction has an outward compression.



   With regard to the strength of the webs between the perforation holes of the upper end of the tape into which the barb hooks, the distance between immediately adjacent perforation holes in the circumferential direction of the clamp always has a value of a certain importance; This leads to the fact that for the hooking of the barb into a perforation hole in the upper end of the belt to produce the required hoop tension, under certain circumstances very considerable forces have to be transferred to the clamp. This is especially the case when the step between two perforation holes is large and sufficient hoop tension is almost reached when the barb is hooked into the perforation hole adjacent to the upper end of the tape, but the barb should still hook into the next perforation hole.

  In such cases, the forces necessary for pulling the ends of the band together cannot easily be transferred to the same with conventional clamps, that is to say in a simple, time-saving and secure manner. In other words, there is a risk of expanding pliers, for example, slipping off, with the contraction process often having to be restarted.



  Particularly in the case of a thin hose wall and / or hose material that is not particularly elastic, it may be unavoidable to install a spring element in the band of the clamp, which increases costs.



   The invention makes use of the progress made in the main patent, which consists in the fact that even a very simple tightening instrument can be easily and reliably attached to the clamp. In addition, it should now be possible to prevent the hinge parts lying on top of one another from shifting laterally.



   According to the invention, the lower end of the tape has an upward, that is to say radially outward, tongue which is axially guided in the slot of the upper end of the tape. With this measure, the hose is protected and an axial coverage of the tape ends lying one above the other is ensured.



   In the drawing, an embodiment of a clamp is shown in simplified form. The single figure shows an axial view of a partially sectioned open clamp, the reference numerals 1 to 10 corresponding to those of the drawing of the main patent.



   The lower end of the tape 4 has a tongue 14 which is bent radially outwards, that is to say upward, and which is axially guided in the slot 9 of the upper end of the tape (2).
