DESCRIPTIONDESCRIPTION
DOMAINE DE L’INVENTIONFIELD OF THE INVENTION
La présente invention concerne un dispositif de blocage d’un élément mâle coulissant dans un élément femelleThe present invention relates to a device for blocking a male element sliding in a female element
EXPOSE DE L’ARRIERE PLAN TECHNOLOGIQUEPRESENTATION OF THE TECHNOLOGICAL BACKGROUND
La technique antérieure enseigne essentiellement un dispositif de serrage constitué d’une vis qui traverse un trou taraudé dans la paroi de l’élément femelle pour venir exercer une pression de serrage sur l’élément mâle. Un contre-écrou peut être utilisé pour le maintien de ladite vis dans la position souhaitée.The prior art essentially teaches a clamping device consisting of a screw which passes through a tapped hole in the wall of the female element in order to exert a clamping pressure on the male element. A lock nut can be used to hold said screw in the desired position.
L’inconvénient majeur d’un tel dispositif réside dans le fait que l’extrémité de la vis de blocage, qui est directement au contact de la partie mâle, s’écrase de plus en plus au fur et à mesure des serrages jusqu’au point de ne plus pouvoir être dévissée.The major drawback of such a device lies in the fact that the end of the locking screw, which is directly in contact with the male part, becomes more and more crushed as and when tightening up to point of no longer being able to be unscrewed.
RESUME DE L’INVENTIONSUMMARY OF THE INVENTION
L’invention vise à proposer un dispositif de blocage d’un élément mâle coulissant dans un élément femelle ne présentant pas l’inconvénient susmentionné, autrement dit éliminant le contact direct du moyen de blocage pourvu d’un filetage avec ledit élément mâle.The invention aims to propose a device for blocking a male element sliding in a female element which does not have the aforementioned drawback, in other words eliminating direct contact of the blocking means provided with a thread with said male element.
Le dispositif de blocage selon l’invention se caractérise essentiellement en ce qu’il comporte :The locking device according to the invention is essentially characterized in that it comprises:
- un tube de guidage solidarisé à l’élément femelle ;- a guide tube secured to the female element;
- un pion de blocage apte à coulisser dans ledit tube de guidage et à exercer une pression de blocage sur l’élément mâle ;- a blocking pin capable of sliding in said guide tube and exerting blocking pressure on the male element;
- un bouchon femelle pourvu d’un filetage interne apte à être en prise avec un filetage externe (31) aménagé à l’extérieur du tube de guidage et à déplacer, lors de sa rotation, le pion de blocage (4) de manière à l’amener au contact de l’élément mâle. Selon des particularités de réalisation du dispositif de blocage selon l’invention, le pion de blocage, qui est réalisé en acier traité :- A female plug provided with an internal thread able to be engaged with an external thread (31) arranged outside the guide tube and to move, during its rotation, the blocking pin (4) so as to bring it into contact with the male element. According to particular features of the blocking device according to the invention, the blocking pin, which is made of treated steel:
- est surmonté d’une excroissance apte à le maintenir dans le tube en l’absence du bouchon, autrement dit à ne pas le perdre en usage courant ;- is surmounted by a protuberance capable of holding it in the tube in the absence of the stopper, in other words of not losing it in current use;
- est maintenu en position rentrée grâce à une rondelle élastique facilitant le réemboîtement des deux parties coulissantes ;- is kept in the retracted position thanks to an elastic washer facilitating the repositioning of the two sliding parts;
- comporte une rainure longitudinale dans laquelle coulisse un moyen, solidaire de la paroi du tube, apte à assurer le guidage longitudinal et le positionnement optimal dudit pion sur l’élément mâle.- Has a longitudinal groove in which slides a means, integral with the wall of the tube, capable of ensuring longitudinal guidance and optimal positioning of said pin on the male element.
