Description
La présente invention est relative à un dispositif de fixation en aveugleThe present invention relates to a blind fastening device
comprenant un corps apte à être placé sous contrainte et réalisé en une matière élastique, destiné à être inséré dans une ouverture d'un support pour être relié à celui-ci, et un organe métallique fileté formant écrou, fixé dans ledit corps apte à être placé comprising a body capable of being placed under stress and made of an elastic material, intended to be inserted into an opening of a support to be connected to it, and a threaded metallic member forming a nut, fixed in said body capable of being square
sous contrainte.under constraint.
Les dispositifs de fixation en aveugle du type précité sont connus dans la technique Lorsqu'on visse une vis dans l'organe fileté, la portion du corps en matière élastique, par exemple en caoutchouc, qui est située entre la face arrière du support et l'écrou est déformée et dilatée radialement pour former un bourrelet qui vient en contact avec la surface arrière du support autour du trou de fixation De cette manière on obtient une fixation dans laquelle les organes devant être fixés ensemble ne sont pas couplés mécaniquement de façon rigide du fait que la fixation assure un amortissement des oscillations dû à la flexibilité de la matière du corps en caoutchouc De plus, ces dispositifs de fixation en aveugle peuvent être utilisés de façon répétitive L'opérateur doit cependant noter que la vis doit être vissée suffisamment loin pour que le corps en caoutchouc forme une tête d'immobilisation faible et étanche, tandis qu'un vissage trop poussé devra être évité en raison du fait que le corps en caoutchouc peut être déformé de façon excessive, conduisant à une surcharge de la matière au-delà de ses limites d'élasticité En outre, il n'est pas possible de mesurer un couple de mise sous contrainte qui soit bien défini du fait que la fixation est par définition relativement Blind fasteners of the aforementioned type are known in the art When a screw is screwed into the threaded member, the portion of the body of elastic material, for example rubber, which is located between the rear face of the support and the the nut is deformed and expanded radially to form a bead which comes into contact with the rear surface of the support around the fixing hole In this way a fixing is obtained in which the members to be fixed together are not mechanically rigidly coupled from the fact that the fixing ensures damping of the oscillations due to the flexibility of the material of the rubber body In addition, these blind fixing devices can be used repeatedly The operator must however note that the screw must be screwed far enough to that the rubber body forms a weak and watertight immobilization head, while over-tightening must be vity due to the fact that the rubber body can be excessively deformed, leading to an overload of the material beyond its elastic limits In addition, it is not possible to measure a stressing torque which is well defined by the fact that fixation is by definition relatively
souple en raison de l'élasticité du corps en caoutchouc. flexible due to the elasticity of the rubber body.
Le but de l'invention est de réaliser un dispositif perfectionné de fixation en aveugle qui assure une sécurité du montage accrue lorsque la vis est serrée, et The object of the invention is to provide an improved blind fastening device which provides increased mounting security when the screw is tightened, and
une durée d'utilisation prolongée. an extended period of use.
L'invention a en conséquence pour objet un dispositif de fixation en aveugle, destiné à fixer un organe à travers un trou d'un élément de support, du type comprenant un corps apte à être placé sous contrainte, fait d'une matière élastique, destiné à être inséré dans le trou du support pour être relié à celui-ci, et un organe métallique fileté formant écrou, fixé dans le corps apte à être placé sous contrainte, et dans lequel la portion du corps située entre l'écrou et le trou est déformée pour constituer une tête d'immobilisation, et comprenant en outre un manchon formant entretoise à The invention therefore relates to a blind fastening device, intended to fix a member through a hole in a support element, of the type comprising a body capable of being placed under stress, made of an elastic material, intended to be inserted into the hole of the support to be connected to it, and a threaded metallic member forming a nut, fixed in the body capable of being placed under stress, and in which the portion of the body located between the nut and the hole is deformed to constitute an immobilization head, and further comprising a sleeve forming a spacer
l'intérieur dudit corps, entre l'écrou et le trou. inside said body, between the nut and the hole.
Suivant l'invention, qui prévoit un manchon formant entretoise disposé dans le corps apte à être placé sous contrainte, et adjacent à l'écrou, la déformation du corps flexible pour former une tête d'immobilisation est limitée par l'entretoise, qui est forcée par l'écrou à venir en contact avec la surface arrière de la pièce à fixer En conséquence, la longueur de l'entretoise est choisie de manière à permettre, d'une part, de former une tête d'immobilisation bien définie pour une fixation fiable, tout en empêchant, d'autre part, le serrage excessif du corps flexible Lorsque l'entretoise entre en contact avec ladite face arrière, le couple appliqué à la vis augmente de façon notable Ceci constitue une indication fiable que According to the invention, which provides a spacer sleeve disposed in the body capable of being placed under stress, and adjacent to the nut, the deformation of the flexible body to form an immobilization head is limited by the spacer, which is forced by the nut to come into contact with the rear surface of the part to be fixed Consequently, the length of the spacer is chosen so as to allow, on the one hand, to form a well-defined immobilization head for a reliable fixing, while preventing, on the other hand, excessive tightening of the flexible body When the spacer comes into contact with said rear face, the torque applied to the screw increases significantly This constitutes a reliable indication that
la fixation est achevée.fixation is complete.
La description qui va suivre, en regard du dessin The following description, next to the drawing
annexé donné à titre d'exemple non limitatif exposera de attached given by way of non-limiting example will expose
façon détaillée comment l'invention peut être réalisée. in detail how the invention can be realized.
La figure 1 est une vue en coupe d'un dispositif de fixation en aveugle suivant l'invention, avec un écrou inséré avant montage; la figure 2 est une vue en coupe du dispositif de la Figure 1 is a sectional view of a blind fastening device according to the invention, with a nut inserted before mounting; Figure 2 is a sectional view of the device of the
figure 1, montrant la vis fixée.Figure 1, showing the attached screw.
Le dispositif représenté de fixation en aveugle avec écrou comprend un corps cylindrique flexible 1 apte à être placé sous contrainte, réalisé en une matière élastique, par exemple en caoutchouc, qui comporte une collerette 2 venue de matière L'extrémité du corps flexible 1 opposée à la collerette 2 loge un organe métallique 4 ayant un filetage interne 3, et formant écrou L'organe fileté 4 peut être fixé par vulcanisation dans le corps flexible 1, ou peut être maintenu positivement sur ce corps, ou fixé sur celui-ci de toute autre façon Une portion 7 du corps flexible située entre la collerette 2 et l'extrémité 6 de l'organe 4 est déformée pour former une tête 8 d'immobilisation, comme représenté à la figure 2, lorsqu'un élément 10 devant être fixé, disposé en contact avec la collerette 2, est fixé dans un trou d'un support The device shown for blind fastening with nut comprises a flexible cylindrical body 1 capable of being placed under stress, made of an elastic material, for example rubber, which comprises a flange 2 made of material The end of the flexible body 1 opposite to the flange 2 houses a metal member 4 having an internal thread 3, and forming a nut The threaded member 4 can be fixed by vulcanization in the flexible body 1, or can be held positively on this body, or fixed on it anyway other way A portion 7 of the flexible body located between the flange 2 and the end 6 of the member 4 is deformed to form an immobilization head 8, as shown in FIG. 2, when an element 10 having to be fixed, disposed in contact with the flange 2, is fixed in a hole in a support
14 par vissage d'une vis 11 dans l'organe fileté 4. 14 by screwing a screw 11 into the threaded member 4.
Entre l'extrémité 6 de l'organe 4 et l'élément 10 est disposé un manchon 12 formant entretoise, qui peut être déplacé axialement, et dont la longueur est déterminée de manière que l'organe 4 vienne en appui sur l'élément 10 par l'intermédiaire de l'entretoise 12, lorsque la vis 11 est visée jusqu'à ce que la tête d'immobilisation 8 soit formée pour obtenir une fixation sûre, mais sans déformation excessive du corps en Between the end 6 of the member 4 and the element 10 is disposed a sleeve 12 forming a spacer, which can be moved axially, and the length of which is determined so that the member 4 comes to bear on the element 10 by means of the spacer 12, when the screw 11 is aimed until the immobilization head 8 is formed to obtain a secure fixing, but without excessive deformation of the body in
caoutchouc dans la portion 7.rubber in portion 7.
Pour le démontage, il existe deux possibilité: après desserrage de la vis 11, le corps 1 apte à être placé sous contrainte peut revenir élastiquement à sa forme initiale, de sorte que l'élément 10, la vis 11 et l'écrou 4 peuvent être retirés En conséquence, le dispositif de fixation en aveugle agit comme un organe de verrouillage et d'immobilisation rapide Par ailleurs, le dispositif de fixation en aveugle peut adhérer au support 14 après que la vis 11 a été déserrée et retirée de sorte que l'élément 10, par exemple un couvercle, puisse être retiré. La longueur du manchon 12 formant entretoise est fonction de l'épaisseur de l'élément 10 et de celle du support 14, compte tenu de la longueur de la portion 7 qui doit être déformée, et est choisie de manière que la matière flexible ne soit pas surchargée lorsque le corps For disassembly, there are two possibilities: after loosening the screw 11, the body 1 able to be placed under stress can resiliently return to its initial shape, so that the element 10, the screw 11 and the nut 4 can be removed As a result, the blind fastening device acts as a fast locking and immobilizing member Furthermore, the blind fastening device can adhere to the support 14 after the screw 11 has been loosened and removed so that the element 10, for example a cover, can be removed. The length of the sleeve 12 forming a spacer depends on the thickness of the element 10 and that of the support 14, taking into account the length of the portion 7 which must be deformed, and is chosen so that the flexible material is not not overloaded when the body
en caoutchouc est placé sous contrainte. rubber is placed under stress.
Le diamètre externe de l'entretoise 12 est de préférence légèrement supérieur au diamètre interne de la portion 7 afin d'immobiliser l'entretoise par friction pour empêcher sa chute, tout en permettant sont déplacement facile au cours du montage afin d'agir comme The external diameter of the spacer 12 is preferably slightly greater than the internal diameter of the portion 7 in order to immobilize the spacer by friction to prevent it falling, while allowing its easy movement during assembly in order to act as
un contre-support entre l'élément 10 et l'écrou 4. a counter-support between the element 10 and the nut 4.
Dans un autre mode de réalisation, non représenté, le dispositif de fixation en aveugle est à fond fermé, c'est-à-dire que son extrémité qui est opposée au côté d'introduction de la vis peut être fermée pour assurer une protection contre une contamination atmosphérique En variante, l'écrou 4 comporte un trou taraudé borgne, In another embodiment, not shown, the blind fastening device is closed bottom, that is to say that its end which is opposite to the insertion side of the screw can be closed to provide protection against atmospheric contamination As a variant, the nut 4 has a blind tapped hole,
c'est-à-dire ayant un fond ferme.that is to say having a firm bottom.
