Abstract
Description
La présente invention concerne une structure télescopique, en particulier une gaffe pour usage nautique.The present invention relates to a telescopic structure, in particular a boat hook for nautical use.
Comme cela est connu, pour faciliter l'amarrage de petites embarcations et d'autres opérations semblables, un instrument approprié, du type crochet, désigné habituellement sous le terme "gaffe", est utilisé dans le domaine nautique.As is known, to facilitate the mooring of small boats and other similar operations, an appropriate instrument, of the hook type, usually designated by the term "hook", is used in the nautical field.
Habituellement, on utilisedes gaffes télescopiques constituées en particulier par une paire d'éléments tubulaires qui peuvent coulisser l'un dans l'autre, l'élément interne de ceux-ci étant muni à son extrémité d'un élément d'accrochage en forme de crochet.Usually, telescopic hooks are used, constituted in particular by a pair of tubular elements which can slide one inside the other, the internal element of these being provided at its end with a hooking element in the form of hook.
Pour verrouiller lesdits éléments tubulaires dans la position axiale requise, on prévoit en général un manchon, qui peut coulisser sur le tube interne et peut êtr; vissé sur le tub- externe. Cependant, ce manchon n'assure pas un verroÜLllage sûr des deux éléments tubulaires télescopiques, de sorte que, souvent, quandla cortrainte axiale augmente, les tubes s'échappent.To lock said tubular elements in the required axial position, a sleeve is generally provided, which can slide on the internal tube and can be; screwed onto the outer tube. However, this sleeve does not ensure a secure locking of the two telescopic tubular elements, so that, often, when the axial stress increases, the tubes escape.
Le but de la présente invention est de résoudre le problème indiqué ci-dessus grâce à une gaffe pour usage nautique qui garas t un verrouillage stable des éléments télescopiques même sous une charge axiale importante.The object of the present invention is to solve the problem indicated above by means of a boat hook for nautical use which guarantees stable locking of the telescopic elements even under a high axial load.
De plus, un objet de l'invention est de fournir une gaffe pour usage nautique qui est de concept simple, fable en service, qui présente une grande souplesse d'application, et qui est relativement économique.In addition, an object of the invention is to provide a boat hook for nautical use which is of simple concept, reliable in service, which has great flexibility of application, and which is relatively economical.
A cet effet, la structure télescopique, en particulier une gaffe pour usage nautique, comprenant un élément tubulaire interne et un élément tubulaire externe adaptés pour coulisser l'un dans l'autre, est remarquable, selon l'invention, en ce que l'élément tubulaire interne présente au moins une partie longitudinale aplatie moletée, une bague étant extérieurement associée rigidement à l'élément tubulaire externe et présentant au moins une dent élastique qui traverse ledit élément tubulaire externe, un manchon conique étant porté, de façon coulissante, sur ledit élément tubulaire interne pour engager ladite bague et pousser ladite dent contre ladite partie aplatie moletée pour le verrouillage mutuel desdits éléments tubulaires.To this end, the telescopic structure, in particular a boat hook for nautical use, comprising an internal tubular element and an external tubular element adapted to slide one inside the other, is remarkable, according to the invention, in that the internal tubular element has at least one flattened knurled longitudinal part, a ring being externally rigidly associated with the external tubular element and having at least one elastic tooth which passes through said external tubular element, a conical sleeve being slidably carried on said internal tubular element for engaging said ring and pushing said tooth against said knurled flat part for mutual locking of said tubular elements.
Selon une autre caractéristique de l'invention, lac tue bague comprend une pluralité de bras uniformément espacés s'étendant longitudinalement le long desdits éléments tubulaires et définissant à une extrémité des dents respectives s'étendant vers ledit élément tubulaire externe, traversant des orifices respectifs formés dans ledit élément tubulaire externe et engageant des parties aplaties moletées cDrrespondantes dudit élément tubulaire interne.According to another characteristic of the invention, the ring killer comprises a plurality of uniformly spaced arms extending longitudinally along said tubular elements and defining at one end respective teeth extending towards said external tubular element, passing through respective orifices formed into said external tubular element and engaging corresponding flat knurled portions of said internal tubular element.
Avantageusement, ledit manchon présente une partie conique et une partie cylindrique filetée intérieurement pour son vissage sur un filetage externe correspondant de ladite bague.Advantageously, said sleeve has a conical part and a cylindrical part internally threaded for its screwing on a corresponding external thread of said ring.
En particulier, ladite bague peut être agencée à proximité d'une extrémité dudit élément tubulaire externe entourant ledit élément tubulaire interne.In particular, said ring can be arranged near one end of said external tubular element surrounding said internal tubular element.
Selon une autre caractéristique de l'invention, ledit élément tubulaire interne définit, à son extrémité libre, un élément d'accrochage en forme de crochet.According to another characteristic of the invention, said internal tubular element defines, at its free end, a hooking hook-shaped element.
Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée. The figures of the appended drawing will make it clear how the invention can be implemented.
La figure 1 est une tue latérale, avec arrachement et coupe partiels, de la gaffe selon l'invention.Figure 1 is a side kill, with cutaway and partial section, of the gaff according to the invention.
La figure 2 est une vue en coupe selon la ligne Il-Il de la figure î. Figure 2 is a sectional view along line II-II of Figure 1.
En référence au dessin, la gaffe télescopique selon l'invention est généralement constituée par une paire d'éléments tubulaires 1 et 2, désignés respectivement ci-après comme élément interne et élément externe, qui peuvent coulisser l'un dans l'autre de façon télescopique.With reference to the drawing, the telescopic hook according to the invention is generally constituted by a pair of tubular elements 1 and 2, designated respectively below as internal element and external element, which can slide one inside the other so telescopic.
Le tube interne 1 est muni, fixé à une extrémité, d'un élément d'accrochage 3 en forme de crochet, d'un type connu.The internal tube 1 is provided, fixed at one end, with a hooking element 3 in the form of a hook, of a known type.
Sur le tube externe 2, est montée, à proximité de l'extrémité à partir duquel fait saillie le tube interne 1, une bague 4 munie extérieurement d'un filetage 4a. A partir de la bague 4, s'étend, de façon longitudinale audit tube, une pluralité de petits bras 5 angulairement espacés. De faon appropriée, quatre petits bras son prévus, décalés d'un quart de circonférence l'un par rapport à l'autre. Les petits bras 5 définissent, à leurs extrémités, une dent 6 dirigée vers l'intérieur des tubes.On the outer tube 2, is mounted, near the end from which the inner tube 1 projects, a ring 4 externally provided with a thread 4a. From the ring 4, extends, longitudinally to said tube, a plurality of small arms 5 angularly spaced. Appropriately, four small arms are provided, offset by a quarter of circumference relative to each other. The small arms 5 define, at their ends, a tooth 6 directed towards the inside of the tubes.
Les dents 6 traversent des orifices respectifs formés dans le tube externe 2, de façon à engager la surface moletée de parties aplaties correspondantes 7 prévues longi=udinale- ment sur le tube interne 1.The teeth 6 pass through respective orifices formed in the external tube 2, so as to engage the knurled surface of corresponding flattened parts 7 provided lengthwise on the internal tube 1.
Le tube interne î porte, de façon coulissante, un manchon 8 qui est adapté pour engager la bague 4 du tube externe 2.The internal tube I carries, in a sliding manner, a sleeve 8 which is adapted to engage the ring 4 of the external tube 2.
Plus particulièrement, le manchon 8 présente une partie cylindrique 8a munie intérieurement d'un filetage Sc, reliée à une partie conique 8b, convergeant vers le tube interne 1. More particularly, the sleeve 8 has a cylindrical part 8a provided internally with a thread Sc, connected to a conical part 8b, converging towards the internal tube 1.
Le manchon 8 est destiné à être vissé sur le filetage i4a de la bague 4 par sa partie 8c, de façon à serrer, grâce à sa partie conique, les dents 6 contre les parties aplaties moletées 7 correspondantes du tube interne. Ce serrage est provoqué par la flexion des bras courts 5 qui portent les dents 6.The sleeve 8 is intended to be screwed onto the thread i4a of the ring 4 by its part 8c, so as to tighten, thanks to its conical part, the teeth 6 against the corresponding knurled flattened parts 7 of the internal tube. This tightening is caused by the bending of the short arms 5 which carry the teeth 6.
De cette façon, un couplage stable des deux éléments télescopiques dans la position souhaitée est obtenu. On doit noter qu'à la fois le verrouillage et le déverrouillage des deux éléments tubulaires de la gaffe peuvent être réalisés de façon très rapide et simple, puisqu'il suffit pour cela de simplement vïsser ou dévisser le manchon 8.In this way, a stable coupling of the two telescopic elements in the desired position is obtained. It should be noted that both the locking and unlocking of the two tubular elements of the hook can be carried out very quickly and simply, since it suffices for this to simply screw or unscrew the sleeve 8.
En pratique, le système de fixation selon l'invention peut être utilisé dans tous es cas où il est nécessaire de verrouiller axialement deux éléments tubulaires télescopiques, tels que par exemple des manches de balai, et analogues. In practice, the fixing system according to the invention can be used in all cases where it is necessary to axially lock two telescopic tubular elements, such as, for example, broom handles, and the like.
