Device for attaching one object to another. The present invention relates to a positive device for fixing one object to another, comprising a threaded metal doilile drowning in a hole of one of res objects and a screw! of fixati: onse screwing in rette socket. This device is characterized in that the wall of the sleeve has longitudinal slots made from the end through which the screw is intended to penetrate, a frustoconical part located between the head of the screw and its threaded end penetrating in the split end of the socket when screwing the screw into this socket, so as to separate them by deforming them. tabs formed in the wall of the socket by the slots to force the tabs against the wall of the hole in order to secure the socket in the hole.
Le dessin ei-annexe represente, ä titre d'@exemple, deux formen d'execution de 1'ob- jet de 1'invention. The appended drawing shows, by way of example, two embodiments of the object of the invention.
La fig. 1 est une vue en coupe axiale de la. Premiere forme avec la vis en place. La fig. 2 st une vue en caupe de la meme pen- daut son montage. La fig. 3 est une coupe suivant III-III de la fig. 2. fig. 1 is an axial sectional view of the. First form with the screw in place. fig. 2 is a top view of the same during its assembly. fig. 3 is a section along III-III of FIG. 2.
La fig. 4 est une vue en Elevation de la vis de la deuxieme forme d'execution. fig. 4 is an Elevation view of the screw of the second embodiment.
La dispasitif represente aug fig. 1 ä 3 comprend une douille metallique tubulaire taraudee 3, 4, dont la forme initiale est re- pr6sent6e en fig. 2 et 3. C'est celle d'un man- chon qui presente, ä 1'exterieur, des nervuress 10 faisant saillie sur sa surface exterieure cy- lindrique. La paroi de la douille 3 presente des fentes longitudinales 9 pratiquees ä par- tir de l'une de ses extremites sur une Partie de sa longueur et, e, rette meme extremite, son alesage est legerement evase coniquement pour faciliter la Penetration de 1'extremite filetee 5 de 1a vis. La tige de rette vis pre- sente, entre sa Partie filetee 5 et sa tete 8, une Partie cylindrique lisse 6 sur laquelle est ajuste amoviblement un manehon 7 dont la surface exterieure est tronconique ä une ,extremite, de fügen que 1e bord correspondant seit tranchant. Cette Partie tronconique 11 est destinee ä penetrer dann 1'extremite fen- due de la douille 3 lors du vissage de .la vis dans cette douille, de façon à écarter, en les déformant d'une manière permanente, les lan- guettes constituées dans la paroi de la douille par .les fentes. Ces languettes sont ainsi for cées contre la paroi du trou de la planche 1 dans lequel la douille est logée et pénétrant en partie dans cette paroi de façon à figer la douille dans le trou. The device represents aug fig. 1 to 3 comprises a threaded tubular metal sleeve 3, 4, the initial shape of which is shown in FIG. 2 and 3. It is that of a sleeve which has, on the outside, ribs 10 projecting from its cylindrical outer surface. The wall of the casing 3 has longitudinal slots 9 made from one of its ends over a part of its length and, at the same end, its bore is slightly flared conically to facilitate the penetration of the threaded end 5 of the screw. The screw rod has, between its threaded part 5 and its head 8, a smooth cylindrical part 6 on which is removably fitted a crank pin 7, the outer surface of which is frustoconical at one end, so that the corresponding edge sharp. This frustoconical part 11 is intended to penetrate into the split end of the sleeve 3 when the screw is screwed into this sleeve, so as to separate, by permanently deforming them, the tongues the wall of the socket by .the slots. These tabs are thus forced against the wall of the hole in the board 1 in which the sleeve is housed and partly penetrating into this wall so as to fix the sleeve in the hole.
On voit que !la partie 6 de la tige de la vis et le manchon 7 ont des longueurs supé- rieures à l'épaisseur d'une planche 2 qu'il s'agit de fixer contre la planche 1, afin que la douille soit entièrement noyée dans la planche 1 avant le serrage de la vis; de cette manière, les extrémités des languettes écar tées de la douille incrustées dans la planche; sont retenues contre des efforts d'arrache ment par la matière de la planche comprise entre elles et la face de la planche 1. It can be seen that the part 6 of the screw rod and the sleeve 7 have lengths greater than the thickness of a board 2 which is to be fixed against the board 1, so that the sleeve is completely embedded in the board 1 before tightening the screw; in this way, the ends of the spread tabs of the sleeve embedded in the board; are retained against tearing forces by the material of the board between them and the face of the board 1.
Le dispositif présente ainsi les avantages d'une vis à bois par cet effet de retenue dans des matériaux tendres comme le bois, le plâtre, le mortier, en même temps que les avantages d'une vis à métaux qui supporte un nombre indéfini de serrages et de des- serrages. The device thus has the advantages of a wood screw by this retaining effect in soft materials such as wood, plaster, mortar, at the same time as the advantages of a metal screw which supports an indefinite number of tightenings. and loosening.
Dans le cas où la partie 2 à fixer serait en métal, on pourrait faire la douille 7 plus courte, de manière que la tête 8 au lieu d'a gir directement presse sur elle par l'intermé diaire de cette partie en métal. In the case where the part 2 to be fixed is made of metal, the socket 7 could be made shorter, so that the head 8 instead of acting directly presses on it via this metal part.
La fig. 4 montre que la surface tronco nique 14 peut être présentée par la tige de la vis elle-même dont la partie lisse 13 est alors plus grosse en diamètre que la partie filetée. La douille de cette forme d'exécution est identique à celle des fig. 1 à 3. fig. 4 shows that the frustoconical surface 14 can be presented by the shank of the screw itself, the smooth part 13 of which is then larger in diameter than the threaded part. The socket of this embodiment is identical to that of FIGS. 1 to 3.
Au lieu d'être de section circulaire et d'être munie d'aspérités extérieures, la douille pourrait avoir une section de contour exté- rieur polygonal afin de ne pouvoir tourner dans son trou. De toute manière, la douille sera introduite à force dans son logement avant d'être soumise à l'effort des surfaces l l ou 14. Instead of having a circular section and being provided with external roughness, the sleeve could have a section with a polygonal external contour so as not to be able to turn in its hole. In any case, the sleeve will be forced into its housing before being subjected to the force of the surfaces 11 or 14.
La tête de la vis pourrait avoir toute autre forme connue et être fendue. The head of the screw could have any other known shape and be slotted.
