Abstract
Description
La présente invention concerne un dispositif permettant de réaliser la solidarisation et le verrouillage de deux éléments de forme tubulaire. The present invention relates to a device for securing and locking two elements of tubular shape.
La particularité de ce système réside dans le fait que tous les éléments d'assuJettissement et de verrouillage des pièces entre elles sont intérieurs à celles-ci et de ce fait se trouvent hors de portée des personnes non concernées. The peculiarity of this system lies in the fact that all the elements for subduing and locking the parts between them are internal to them and therefore are out of the reach of those not concerned.
Dans un certain nombre de cas, notamment pour des installations concernant les services publics, il est utile de pouvoir mettre en place ou retirer aisément des éléments d'équipement. Il est indispensable également que ces éléments soient ancrés de façon inviolable tout en réservant la condition d'amovibilité qui leur est nécessaire. In a certain number of cases, in particular for installations relating to public services, it is useful to be able to easily install or remove elements of equipment. It is also essential that these elements are anchored in an inviolable manner while reserving the condition of removability which is necessary for them.
Le dispositif selon l'invention permet de satisfaire à ces critères. The device according to the invention makes it possible to satisfy these criteria.
Il comporte trois aménagements des pièces à assembler dont la combinaison permet d'aboutir au résultat recherché. Le premier de ces aménagements consiste dans la forme tronconique des extrémités des pièces, l'une d'elle étant mâle et l'autre femelle avec des dimensions et angles permettant leur adaptation.It includes three arrangements of the parts to be assembled, the combination of which allows the desired result to be achieved. The first of these arrangements consists of the frustoconical shape of the ends of the parts, one of them being male and the other female with dimensions and angles allowing their adaptation.
Le deuxième aménagement est constitué par des rampes établies les unes dans la partie intérieure de l'un des éléments et les autres sur la partie extérieure de l'autre élément. Le nombre de ces rampes est indifférent. The second arrangement consists of ramps established one in the inner part of one of the elements and the others on the outer part of the other element. The number of these ramps is indifferent.
Ces rampes sont établies de telle manière que lorsque les éléments sont aboutés par les parties tronconiques précitées, elles se trouvent quinconcées les unes par rapport aux autres. These ramps are established in such a way that when the elements are abutted by the aforementioned frustoconical parts, they are staggered with respect to each other.
Ces rampes dont la section peut être quelconque ont pour génératrices des courbes hélicoides. These ramps, the section of which may be arbitrary, have helical curves as generators.
De la sorte, en faisant effectuer à l'un des éléments une rotation par rapport à l'autre on aménera ces rampes en contact l'une de l'autre et on développera ainsi une composante longitudinale qui assurera la solidarisation des deux éléments. In this way, by causing one of the elements to rotate relative to the other, these ramps will be brought into contact with one another and a longitudinal component will thus be developed which will ensure the joining of the two elements.
Le troisième aménagement est constitué par une pièce qui vient occuper les secteurs libres entre les rampes de l'un et l'autre élément et qui de la sorte interdit tout mouvement de rotation inverse, donc de désolidarisation. The third arrangement consists of a part which occupies the free sectors between the ramps of one and the other element and which in this way prohibits any movement of reverse rotation, and therefore of separation.
Cette pièce est sollicitée à s'insérer dans ces secteurs libres, par l'action dun ressort. This part is requested to fit into these free sectors, by the action of a spring.
Selon les modes particulièrs de réalisation les éléments assemblés peuvent être de section extérieure constante ou comporter des saillies de révolution ou non. Leurs dimensions en section et longueur peuvent être essentiellement quelconques. According to the particular embodiments, the assembled elements can be of constant external section or include projections of revolution or not. Their dimensions in section and length can be essentially any.
Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.
Les figures l et 4 représentent en perspective translucide les éléments à solidariser. Ils sont représentatifs de modules ce qui est un cas parties culier de réalisation. Figures l and 4 show in translucent perspective the elements to be joined. They are representative of modules which is a special case of realization.
La figure 2 représente également en perspective translucide la pièce dite "tulipe de blocage" qui assure le verrouillage du dispositif. Figure 2 also shows in translucent perspective the part called "locking tulip" which ensures the locking of the device.
La figure 3 représente en coupe élévation le ressort de sollicitation de la tulipe de blocage. Figure 3 shows in elevation section the biasing spring of the locking tulip.
En référence à ces dessins le dispositif comporte une emboiture tronconique (l) en correspondance dimensionnelle avec t'about également tronconique (2). Cette disposition permet le positionnement des deux éléments l'un par rapport à l'autre et notamment l'alignement de leurs axes. With reference to these drawings, the device comprises a frustoconical socket (l) in dimensional correspondence with the end also frustoconical (2). This arrangement allows the positioning of the two elements relative to each other and in particular the alignment of their axes.
L'alésage intérieur des éléments comporte trois tronçons de rampes (3). The internal bore of the elements has three sections of ramps (3).
Ce nombre de tronçons représente un cas particulier de réalisation étant entendu qutil peut être quelconque. Dans le cas présenté ces rampes occupent un secteur angulaire d'environ 60 et sont séparées par des espaces libres d'environ 60 également. Ces rampes ont pour génératrices des courbes hélicoïdes comprises entre les deux mêmes grands cercles du cylindre dans lequel elles s'inscrivent.This number of sections represents a particular embodiment given that it can be any. In the case presented, these ramps occupy an angular sector of approximately 60 and are separated by free spaces of approximately 60 also. These ramps have for their generators helical curves comprised between the same two large circles of the cylinder in which they are inscribed.
Le dispositif comporte à sa base dans ce cas particulier de réalisation, un Jeu de 3 rampes (4) en correspondance avec les précédentes et implantées de la même manière. The device comprises at its base in this particular embodiment, a set of 3 ramps (4) corresponding to the previous ones and installed in the same way.
Lorsque lton introduit ltélément de la figure l dans celui de la figure 4 les rampes (4) trouvent leur passage dans les intervalles existant entre les rampes (3) et permettent ainsi la venue au contact des deux parties tronconiques (l) et (2) de guidage Dans cette position les rampes (4) se trouvent à un niveau Légèrement inférieur à celui des rampes (3). When the element of FIG. 1 is introduced into that of FIG. 4, the ramps (4) find their passage in the intervals existing between the ramps (3) and thus allow the coming into contact of the two frustoconical parts (l) and (2). In this position, the ramps (4) are at a level Slightly lower than that of the ramps (3).
Il est alors possible de faire effectuer une rotation à ltélément de la figure (l) (sens des aiguilles d'une montre dans le cas du dessin) ce qui amène les rampes (3) et (4) en contact les unes des autres et développe ainsi la composante de force longitudinale assurant la solidarisation des éléments. It is then possible to rotate the element of figure (l) (clockwise in the case of the drawing) which brings the ramps (3) and (4) in contact with each other and thus develops the longitudinal force component ensuring the joining of the elements.
Cette composante peut également assurer la compression d'un Joint afin d'assurer l'étanchéité de la Jonction. This component can also ensure the compression of a Joint in order to ensure the tightness of the Junction.
Le verrouillage de l'assemblage ainsi réalisé sera assuré par la tulipe de blocage (8) assistée du ressort (6). La mise en place de ces pièces devra être effectuée avant le rapprochement des éléments Fig. l et Fig. 4. The locking of the assembly thus produced will be ensured by the locking tulip (8) assisted by the spring (6). The installation of these parts must be carried out before the elements are brought together. l and Fig. 4.
Le ressort (6) sera tout d'abord mis en place sur la tablette (5) de ltélément Fig. 4 puis la tulipe (8) introduite à son tour et assise sur le ressort. The spring (6) will firstly be placed on the shelf (5) of the element FIG. 4 then the tulip (8) introduced in turn and seated on the spring.
Lors du rapprochement de l'élement à assembler Fig. 1, les rampes inférieures(4) de cet élément font pesée sur la tulipe (8), ce qui comprime le ressort jusqu'la position de contact des parties tronconiques (1) et (2). When the element to be assembled is brought together Fig. 1, the lower ramps (4) of this element are weighed on the tulip (8), which compresses the spring to the contact position of the frustoconical parts (1) and (2).
La tulipe est guidée par des barettes longitudinales intérieures (7). The tulip is guided by internal longitudinal bars (7).
En effectuant la rotation de l'élément à assembler, les rampes, en se décalant les unes par rapport aux autres, feront apparaltre entre elles des secteurs libres dans lesquels s'inséreront les ailettes (9) de la tulipe. By carrying out the rotation of the element to be assembled, the ramps, by shifting with respect to each other, will cause free sectors to appear between them in which the fins (9) of the tulip will be inserted.
Les deux jeux de rampes se trouveront ainsi bloqués l'un par rapport à l'autre, interdisant le déverrouillage du système. The two sets of ramps will thus be blocked relative to each other, preventing the unlocking of the system.
Pour obtenir ce deverrouillage il faudra tout d'abord exercer une pesée sur la tulipe pour extraire les ailettes (9) de leur position d'insertion, puis faire pivoter l'élément Fig. l en sens inverse afin de dégager les rampes. On pourraainsi le séparer de l'élément Fig. 4. To obtain this unlocking, it will first be necessary to weigh the tulip to extract the fins (9) from their insertion position, then rotate the element Fig. l in reverse to clear the ramps. We can thus separate it from the element Fig. 4.
Selon une variante non illustrée, la tulipe pourra avoir une base ajourée afin de permettre la circulation d'un fluide dans le tube. According to a variant not illustrated, the tulip may have an openwork base in order to allow the circulation of a fluid in the tube.
Le dispositif selon l'invention peut trouver son emploi dans de multiples applications. Il a été imaginé pour conférer l'amovibilité à certains équipements urbains tels que des bornes ou candélabres, mais son intérêt peut s'etendre à des domaines divers. The device according to the invention can find its use in multiple applications. It was designed to confer removability to certain urban facilities such as bollards or candelabras, but its interest can extend to various fields.
