Abstract

The subject of the present invention is a nut which is secured to a helical gear 10. The subject of the present invention is also a tool for tightening or loosening this nut. Application: pipe union.

Description

La présente invention a pour objet un écrou qui peut être monté d'une seule main et utilise dans des endroits peu accessibles, le vissage ou le dévissage de l'écrou n'exigeant pas de débattement.The present invention relates to a nut which can be mounted with one hand and uses in inaccessible places, the screwing or unscrewing of the nut not requiring travel.

L'écrou selon l'invention est caractérisé en ce qu'il est solidaire d'un pignon hélicoïdal. The nut according to the invention is characterized in that it is integral with a helical pinion.

L'invention a également pour objet un outil pour le serrage ou le desserrage de cet écrou.The invention also relates to a tool for tightening or loosening this nut.

Cet outil est caractérisé en ce qu'il comprend un corps pouvant être emporté élastiquement sur le pignon et une vis montée pivotante dans le corps et en prise avec le pignon lorsque le corps est embout8 sur le pignon. Il suffit alors de faire pivoter la vis pour serrer ou desserrer l'écrou. La vis peut être solidaire d'un organe de manoeuvre manuel; elle peut également être agencée pour pouvoir être entraînée par un tour nevis manuel ou électrique. Dans le cas de l'emploi d'un tournevis électrique le vissage se fait sans fatigue.This tool is characterized in that it comprises a body which can be carried elastically on the pinion and a screw pivotally mounted in the body and in engagement with the pinion when the body is pressed on the pinion. Then simply rotate the screw to tighten or loosen the nut. The screw may be integral with a manual operating member; it can also be arranged to be able to be driven by a manual or electric screwdriver. When using an electric screwdriver, screwing is done without fatigue.

L'invention est particulièrement applicable à un raccord de canalisation comprenant un corps dans lequel la canalisation peut être enfilée, une rondelle élastique et un écrou pouvant être vissé dans le corps et comprimer la rondelle entre ce corps et la canalisation en solidarisant cette dernière au corps.The invention is particularly applicable to a pipe fitting comprising a body into which the pipe can be threaded, an elastic washer and a nut that can be screwed into the body and compress the washer between this body and the pipe by securing the latter to the body. .

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation d'un raccord muni de l'écrou selon l'invention et de l'outil pour le serrage de cet écrou, avec référence aux dessins annexés dans lesquels :
La Figure 1 est une vue en coupe du raccord;
La Figure 2 est une vue en perspective du
raccord séparé de la canalisation;
La Figure 3 montre en perspective le raccord
enfilé sur la canalisation, l'outil de serrage
n'étant pas en place;
La Figure 4 est une vue semblable à la
Figure 3,
l'outil de serrage étant en place;
La Figure 5 est une vue en élévation d'une va
riante de raccord.An embodiment of a connector provided with the nut according to the invention and the tool for tightening this nut has been described below, by way of non-limiting example, with reference to the accompanying drawings in which :
Figure 1 is a sectional view of the connector;
Figure 2 is a perspective view of the
separate pipe connection;
Figure 3 shows in perspective the fitting
threaded on the pipe, the clamping tool
not being in place;
Figure 4 is a view similar to the
Figure 3,
the clamping tool being in place;
Figure 5 is an elevational view of a va
fitting laughing.

Au dessin, on voit un raccord cylindrique 1 présentant un alésage intérieur 2. Cet alésage comporte une collerette médiane 3 de chaque côté de laquelle se trouvent une portée cylindrique 4 et une portée taraudée 5.In the drawing, we see a cylindrical connector 1 having an internal bore 2. This bore has a central flange 3 on each side of which there is a cylindrical bearing 4 and a threaded bearing 5.

Dans chacune des extrémités de l'alésage 2 peut être emmanché un tuyau 6 sur lequel ont été enfilés une rondelle en caoutchouc7, une rondelle d'appui métallique 8 et un écrou 9 propre à se visser dans la portée taraudée 5.In each end of the bore 2 can be fitted a pipe 6 on which have been threaded a rubber washer 7, a metal support washer 8 and a nut 9 suitable for being screwed into the threaded surface 5.

Pour fixer un tuyau au corps 1, il suffit, après avoir enfilé les rondelles 7 et 8 et l'écrou 9 sur le tuyau, d'emmancher ce dernier dans le corps jusqu'à ce qu'il soit en butée contre la collerette 3, et de visser l'écrou 9. Celui-ci repousse la rondelle 8 qui comprime la rondelle 7 contre la collerette 3; cette rondelle se déforme et vient se coincer entre la paroi de l'alésage 4 et le tube qui est ainsi immobilisé
Selon l'invention, chaque écrou 9 est solidaire d'un pignon denté 10 qui est ici à denture hélicoïdale.To fix a pipe to the body 1, after having threaded the washers 7 and 8 and the nut 9 on the pipe, it suffices to fit the latter into the body until it is in abutment against the collar 3 , and to screw the nut 9. This pushes the washer 8 which compresses the washer 7 against the collar 3; this washer deforms and is wedged between the wall of bore 4 and the tube which is thus immobilized
According to the invention, each nut 9 is integral with a toothed pinion 10 which is here with helical teeth.

L'écrou peut ainsi être serré par un outil qui comprend un corps 11 en matière plastique pouvant être emboité élastiquement sur le pignon 10. Dans ce corps est montee pivotante une vis 12 qui est solidaire d'une molette 13 et est en prise avec le pignon 10 lorsque le corps 11 est emboité sur ce pignon. Il suffit ainsi de faire pivoter la molette pour visser ou desserrer l'écrou 8. Pour empêcher le corps 11 de pivoter avec le pignon 10, le corps 11 présente des évidements 14 dans lesquels peuvent s'engager des cannelures 15 du corps 1.The nut can thus be tightened by a tool which comprises a body 11 of plastic material which can be fitted elastically on the pinion 10. In this body is pivotally mounted a screw 12 which is integral with a thumb wheel 13 and is engaged with the pinion 10 when the body 11 is fitted on this pinion. It therefore suffices to rotate the thumb wheel to screw or loosen the nut 8. To prevent the body 11 from pivoting with the pinion 10, the body 11 has recesses 14 in which grooves 15 of the body 1 can engage.

On peut faire pivoter la molette 13 à la main. Celleci peut également comporter un évidement axial 16 dans lequel on peut engager la lame 17 d'un tournevis manuel ou électrique. You can rotate the wheel 13 by hand. This can also include an axial recess 16 in which the blade 17 can be engaged with a manual or electric screwdriver.

Le raccord peut être double comme représenté aux Figures 1 à 4 ou simple comme on le voit à la Figure 5; dans ce dernier cas le corps 1 comporte une portion filetée 18 à son extrémité opposée à la portion tarau dée 5.The connector can be double as shown in Figures 1 to 4 or simple as seen in Figure 5; in the latter case the body 1 has a threaded portion 18 at its end opposite to the tarau dée portion 5.

Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
