Description

DOUILLE FILETEE A PAROI RINCE ET A BLOCAGE PAR BAGUE
L'invention concerne une douille filetée a paroi mince et å blocage par bague pour permettre la fixation par vis d'objets, dans un matériau de base.
THREADED WALL THREADED BUSHING WITH RING LOCK
The invention relates to a thin-walled threaded bushing with ring locking to allow the fixing by screws of objects, in a basic material.

Dans le cas d'éléments de fixation antérieurs à bague de blocage, tels que ceux décrits dans les brevets US nos 3 44 415 et 4 568 228, la bague de blocage coopère avec un corps de fixation par 'interinédiaire de bords striés ou denteles. Il est parfois difficile de joindre ensemble en correspondance de toe ensembles de bagues de blocage et de corps de fixation. Toutefois, on peut faciliter l'utilisation d'e~.- n-s de fixation a douille filetée bloquée par une bague en revoyant deux fentes symétriques dans le corp de fixation fileté et des saillies complementaires sur la bague de blocage. In the case of prior fixing elements with a locking ring, such as those described in US patents Nos. 3 44 415 and 4 568 228, the locking ring cooperates with a fixing body by means of ridged or serrated edges. It is sometimes difficult to join together in correspondence of toe sets of locking rings and fixing bodies. However, it can facilitate the use of e ~ .- n-s fixing threaded bushing blocked by a ring by reviewing two symmetrical slots in the threaded fixing body and additional projections on the locking ring.

La presente invention procure une douille filetée a paroi mince, de grande résistance et a blocage par bague à insérer à la fois dans des rateriauY durs et des matériaux tendres. Elle forme un filetage intérieur dans un matériau de base sans qu'on ait a brocher celui-ci au préalable. Elle est particulièrement utile lorsque la distance au bord pour placer la douille dans le matériau de base est critique. Pour installer la douille, le matériau est foré, chambré et taraudé de façon qu'on puisse visser la douille dans le matériau de base. La douille pré sente à son extrémité supérieure deux fentes diamètraleznent opposées pour coopérer avec une bague de blocage associée.La bague de blocage trempée spéciale est alors positionnée et guidée par les fentes lorsqu'elle est enfoncée dans le matériau de base. La bague de blocage empêche la douille de sortir par rotation du matériau de base.  The present invention provides a threaded bushing with a thin wall, of great resistance and with blocking by a ring to be inserted both in hard rateriauY and soft materials. It forms an internal thread in a basic material without having to broach it beforehand. It is particularly useful when the distance from the edge to place the sleeve in the base material is critical. To install the socket, the material is drilled, chambered and tapped so that the socket can be screwed into the base material. The bushing has at its upper end two diametrically opposed slots to cooperate with an associated locking ring. The special hardened locking ring is then positioned and guided by the slots when it is pressed into the base material. The locking ring prevents the bushing from rotating out of the base material.

FIG. 7 is a partial longitudinal section of the threaded bush blocked by a ring, taken along line 7-7 of FIG. 6.

Sur la figure 1 une douille filetee 10 à blocage par bague est constituée par une douille filetee 12 présentant à son extrémité superieure deux fentes 14 diamétralement opposées. Les fentes sont dimensionnées et positionnées pour recevoir deux saillies 16 s'étendant radialement vers l'intérieur sur une bague de blocage associée 18. In Figure 1 a threaded sleeve 10 with locking ring is constituted by a threaded sleeve 12 having at its upper end two slots 14 diametrically opposed. The slots are dimensioned and positioned to receive two projections 16 extending radially inwards on an associated locking ring 18.

Comme on le voit sur les figures 2 et 3, la douille filetée 12 est une douille cylindrique creuse ayant un filetage extérieur 2 sur toute sa surface cylindrique extérieure pour coopérer avec un filetage dans le matériau de base. Un filetage intérieur 22 s'étend sur la surface cylindrique intérieure de la douille, depuis le bord inférieur 24 jusqu'a un chambrage 26 menage dans le haut de la surface intérieure de la douille filetée. Ce filetage est -e=--rle a re--evoir un element de fixation filete gnon renre=ente. Le chambrage 26 s'étend depuis le filetage i-ntereur 22 jusqu'au bord supérieur 28 de la douille. As seen in Figures 2 and 3, the threaded sleeve 12 is a hollow cylindrical sleeve having an external thread 2 over its entire external cylindrical surface to cooperate with a thread in the base material. An internal thread 22 extends over the internal cylindrical surface of the sleeve, from the lower edge 24 to a recess 26 formed in the top of the internal surface of the threaded sleeve. This thread is -e = - role to receive - a threaded fastening element gnon renre = ente. The recess 26 extends from the internal thread 22 to the upper edge 28 of the sleeve.

Les fentes 14 sont formees dans la paroi cylindrique du chambrage 26i en des endroits diamétralement opposés sur la douille. Chaque fente comporte une paroi correspondant à une paroi de l'autre fente, se trouvant dans un plan transversal définissant une corde 3 dans la douille filetée.The slots 14 are formed in the cylindrical wall of the recess 26i at diametrically opposite locations on the sleeve. Each slot has a wall corresponding to a wall of the other slot, lying in a transverse plane defining a cord 3 in the threaded bush.

Comme on le voit sur les figures 4 et 5, la bague de blocage 18 comporte des dentelures 32 sur sa surface cylindrique extérieure, avec des cretes 34 et des gorges 36 s'étendant longitudinalement depuis le haut 3 de la bague jusqu'a environ le milieu de celleci. Le reste de la surface cylindrique extérieure de la bague. depuis son milieu jusqu'à son bas 4, est une surface cvlindrique pratiquement lisse. As seen in Figures 4 and 5, the locking ring 18 has serrations 32 on its outer cylindrical surface, with ridges 34 and grooves 36 extending longitudinally from the top 3 of the ring to about the middle of it. The rest of the outer cylindrical surface of the ring. from its middle to its bottom 4, is a practically smooth cylindrical surface.

Le haut 44 de chaque dentelure 32 affleure pratiquement le haut 38 de la bague de blocage. La crete 4 de chaque dentelure est pratiquement parallele a l'axe central 46 de la bague. La surface inférieure 48 de chaque dentelure s'étend en oblique de la portion exterieure ae chaque dentelure vers le haut en direction de la surface cylindrique 42. La surface inférieure oblique de chaque dentelure procure une arete aigué pour faciliter l'enfoncement de la bague de blocage dans le matériau de base. The top 44 of each serration 32 is almost flush with the top 38 of the locking ring. The crest 4 of each serration is practically parallel to the central axis 46 of the ring. The lower surface 48 of each serration extends obliquely from the outer portion of each serration upwards towards the cylindrical surface 42. The oblique lower surface of each serration provides a sharp edge to facilitate the insertion of the ring of blocking in the base material.

La bague de blocage comporte deux surfaces cylindriques intérieures 5 séparées par deux saillies 16 dirigées vers l'intérieur. Chaque saillie a une surface latérale correspondant aux flancs respectifs des fentes 14. Chaque saillie a également une surface cylindrique partielle 52, dont la courbure est semblable à celle du chambrage 26 dans la douille filetée. Les dimensions de la bague de blocage (voir figures 1 et 6) lui permettent de glisser sur la portion supérieure de la bague filetée 12 de façon que les saillies 16 viennent en prise dans les fentes 14 de la douille filetée.  The locking ring has two internal cylindrical surfaces 5 separated by two projections 16 facing inwards. Each projection has a lateral surface corresponding to the respective sides of the slots 14. Each projection also has a partial cylindrical surface 52, the curvature of which is similar to that of the recess 26 in the threaded sleeve. The dimensions of the locking ring (see Figures 1 and 6) allow it to slide over the upper portion of the threaded ring 12 so that the projections 16 engage in the slots 14 of the threaded sleeve.

Avant d'introduire la douille filetee 12 dans le matériau de base 54 revoir figures 6 et 7), celui-ci est tore, chambre pour former un chambrage 56, et taraudé pour former dans le matériau un filetage interne 58. La douille est ensuite vissée dans le matériau de base en utilisant un outil approprié, jusqu'a ce que son bord supérieur 28 se trouve juste en dessous de la surface supérieure 62 du matériau. On place alors le fond de la bague de blocage 18 sur le haut de la douille filetée jusqu'à ce que les deux saillies 16 pénètrent dans les deux fentes 14 de la douille filetée. Before introducing the threaded sleeve 12 into the base material 54 (see Figures 6 and 7), it is toroidal, chamber to form a recess 56, and tapped to form an internal thread 58 in the material. The sleeve is then screwed into the base material using an appropriate tool, until its upper edge 28 is just below the upper surface 62 of the material. The bottom of the locking ring 18 is then placed on the top of the threaded socket until the two projections 16 penetrate into the two slots 14 of the threaded socket.

On guide la bague sur l'extérieur de la douille jusqu'à ce que le fond des dentelures soit en contact avec ie dessus du matériau. Les dentelures de la bague de blocage sont alors enfoncees dans le matériau de base jusqu'a ce que ia surface supérieure de la bague affleure la surface supérieure du matériau. La cooperation des dentelures avec le matériau et des saillies de la bague avec les fentes de la douille empêche la douille de sortir par rotation du matériau de base ou de penetrer davantage dans ce matériau au cas ou il y aurait un espace suffisant.  The ring is guided on the outside of the sleeve until the bottom of the serrations is in contact with the top of the material. The serrations in the locking ring are then pushed into the base material until the upper surface of the ring is flush with the upper surface of the material. The cooperation of the serrations with the material and of the projections of the ring with the slots of the socket prevents the socket from rotating out of the base material or from penetrating further into this material in case there is sufficient space.
