Abstract

The invention relates to a device for tensioning cables, the mechanism being protected against falling water and consequently against rust due to the electrolysis which is promoted by sea water. It consists of a blind nut with a right-hand screw thread 1 including a cable-fixing system 8, of a screw nut 2 with a right-hand thread for the screw and a left-hand thread for the nut, of a screw 5 with a left-hand thread including a system for fixing to an anchoring point (deck of a sailing boat), of two nuts 3 and 4 allowing the assembly to be locked rotationally. The rotation of the screw-nut 2 after immobilisation of the nut 1 and of the screw 5 makes it possible to change the separation between the nut 1 and the screw 5. Since the two nuts 1 and 2 point downwards, they are protected from falling water. The device according to the invention is particularly intended for tensioning the cables of sailing boats.

Description

La présente invention concerne un tendeur de cable. The present invention relates to a cable tensioner.

Les ridoires ou tendeurs de cables sont traditionnellement composés: dun écrou double au pas å droite et a gauche(20)d'une vis (21)au pas a droite et dune vis (22) au pas a gauche;ils sont en général disposés en position verticale entre le pont dun bateau et les cables fixant les mats.Le ruissellement de l'eau de mer le long des cables penetrant dans les filetages provoque une oxydation par éléctrolise de ceux-ci et provoque le blocage des filetages après un certain temps mettant les ridoires hors d'usage.  The turnbuckles or cable tensioners are traditionally composed of: a double nut with a right and left pitch (20) of a screw (21) with a right pitch and a screw (22) with a left pitch; they are generally arranged in vertical position between the deck of a boat and the cables fixing the masts. The runoff of sea water along the cables penetrating into the threads causes oxidation by electrolysis of these and causes the threads to block after a certain time putting the turnbuckles out of use.

La présente invention permet de remédier à cet inconvenient du fait que 1 écrou borgne (1) et la vis-écrou(2)sont conçus en forme de cloche les ouvertures étant dirigées vers le bas protégeant les filetages contre les chutes d'eau.  The present invention makes it possible to remedy this drawback of the fact that 1 blind nut (1) and the screw-nut (2) are designed in the shape of a bell, the openings being directed downwards protecting the threads against falling water.

Selon une variantes le filetage(7)etla vis (5) sont encastrés dans la vis-écrou (2) l'ouverture des de écrous étant dirigée vers le bas.According to a variant the thread (7) and the screw (5) are embedded in the screw-nut (2) the opening of the nuts being directed downwards.

LA figure i représente en coupelle dispositif selon l'invention. FIG. I shows in a device cup according to the invention.

La figure 2 représente en coupe une variante de ce dispositif. Figure 2 shows in section a variant of this device.

La figure 3 représente en coupe un ridoire traditionnel. Figure 3 shows in section a traditional turnbuckle.

Le dispositif représenté sur la figure 1 comporte: un écrou borgne (i) ayant à sa partie supérieure un oeil(8)ou tout autre dispositif permettant d'attacher un cable a sa partie inférieure; un évidement (10) comportant un filetage intérieur au pas a droite destiné a recevoir la vis-écrou(2).Un écrou(3) permet le blocage en rotation de l'écrou borgne(1)avec la vis-écrou(2). La vis-écrou
(2) comporte a sa partie superieure un filetage a droite et a sa partie inférieuré un évidement (11) comportant un filetage interieur a gauche(7) permettant de recevoir la vis à oeil (5).La vis a oeil (5)comporte a sa partie superieure un filetage å gauche et a sa partie inférieure un oeil (9) ou tout autre dispositif permettant sa fixation sur un point d'encrage(pont de bateau). Un écrou(4)permet de bloquer en rotation la vis-écrou(2) avec la vis à oeil(S). The device shown in FIG. 1 comprises: a blind nut (i) having at its upper part an eye (8) or any other device making it possible to attach a cable to its lower part; a recess (10) comprising an internal thread with a right hand pitch intended to receive the screw-nut (2). A nut (3) allows the blocking of the blind nut (1) to rotate with the screw-nut (2) . The screw-nut
(2) has at its upper part a right-hand thread and at its lower part a recess (11) having an internal left-hand thread (7) for receiving the eye screw (5). The eye screw (5) has at its upper part a left-hand thread and at its lower part an eye (9) or any other device allowing its fixing on an anchoring point (boat deck). A nut (4) makes it possible to block the screw-nut (2) in rotation with the eye screw (S).

L'écrou a beil (1) et la vis a oeil(5)étant immobilisés en rotation après avoir désseré les écrous (3) et (4), en tournant la vis-écrou (2) on obtient la variation de l'écartement compris entre l'écrou a oeil(l)et la vis a oeil (5). The bevel nut (1) and the eye screw (5) being immobilized in rotation after having loosen the nuts (3) and (4), by turning the screw-nut (2) we obtain the variation of the spacing between the eye nut (l) and the eye screw (5).

Ru montage des appareils, la graisse introduite dans les évidements (10) et (11) est comprimée par les vis (2) et (5) et chassée au travers des filetages (6) et (7) assurant le parfait graissage de ceux-ci. Ru assembly of the devices, the grease introduced into the recesses (10) and (11) is compressed by the screws (2) and (5) and expelled through the threads (6) and (7) ensuring perfect lubrication of these- this.

Le dispositif selon l'invention est particulièrement destiné a tendre les cables de bateaux à voiles et tout aubanage soumis aux intemperies.  The device according to the invention is particularly intended for stretching the cables of sailing boats and any planking subject to inclement weather.
