DISPOSITIF DE RETENUE AXIALE DsUNE VIS, NOTAMMENT POUR LA FIXATION
DE GLISSIERES DE SINGES SUR UN PLANCHER DE VEHICULE.AXIAL RETAINER FOR A SCREW, PARTICULARLY FOR FIXING
MONKEY SLIDES ON A VEHICLE FLOOR.
L'invention concerne un dispositif de retenue axiale d'une vis, notamment pour la fixation de glissières de sièges sur une face de lancher de véhicule, dans lequel la vis traverse un élément de glissière inférieure et reçoit un écrou de fixation rapporté sur l'autre face du plancher
La publication FR A 2 023 916 décrit des glissières constituées par des cornières de section appropriée entre lesquelles on prévoit des organes de portée affectant la forme de billes roulant sur des pistes formées par les ames et/ou les ailes latérales des cornières dont l'une porte les vis de fixation sur le plancher du véhicule.The invention relates to a device for axially retaining a screw, in particular for fixing seat slides on a vehicle lancer face, in which the screw passes through a lower slide element and receives a fixing nut attached to the other side of the floor
The publication FR A 2 023 916 describes slides constituted by angles of appropriate section between which there are provided bearing members affecting the shape of balls rolling on tracks formed by the webs and / or the lateral wings of the angles, one of which carries the fixing screws on the vehicle floor.
Lorsque le siège du véhicule est préalablement solidarisé Qux glissières avant son montage sur le plancher du véhicule il arrive fréquemment que la pression exercée par ltoutil de vissage déplace l'ensemble du siège et des glissières vers le haut si bien que la position initiale du siège sur le plancher du véhicule se trouve modifiée.When the vehicle seat is previously secured Qux slides before mounting on the vehicle floor it often happens that the pressure exerted by the screwing tool moves the whole of the seat and the slides up so that the initial position of the seat on the vehicle floor is changed.
Le remède/consiste à prévoir sur le plancher des orifices allongés dont l'étendue permet un positionnement préalable du siège avant serrage des écrous n'est pas satisfaisant en raison des précautions de montage qui doivent être observées. Le plus généralement, il s'avère indispensable d'utiliser des cales ou des repères de vérification sans lesquels la rectitude du siège avant la manoeuvre des outils de vissage ne peut être obtenue.The remedy / consists in providing elongated orifices on the floor whose extent allows prior positioning of the seat before tightening the nuts is not satisfactory because of the mounting precautions which must be observed. Most generally, it proves essential to use shims or verification marks without which the straightness of the seat before the operation of the screwing tools cannot be obtained.
Par conséquent l'invention a essentiellement pour objet de remédier aux inconvénients précités et a notamment pour but de réaliser une glissière de siège conventionnelle coopérant avec un dispositif de retenue fixé sur la vis dont la configuration assure principalement le calage de la vis par rapport au plancher et le moyen de retenue axiale de ladite vis au cours du vissage de l'écrou.Consequently, the object of the invention is essentially to remedy the aforementioned drawbacks and in particular has the aim of producing a conventional seat slide cooperating with a retaining device fixed on the screw, the configuration of which mainly secures the screw relative to the floor and the means for axially retaining said screw during the tightening of the nut.
Plus généralement l'objet de l'invention est un dispositif de retenue axiale d'une vis traversant une paroi dont l'extrémité reçoit un écrou vissé.More generally, the object of the invention is an axial retaining device for a screw passing through a wall, the end of which receives a screwed nut.
Conformément à l'invention le dispositif est constitué par une
une face de entretoise orientéevers/la paroi et porte l'orifice de passage de la vis, une série de languettes élastiques réparties à la périphérie, qui possèdent une portée interne lisse d'engagement de l'extrémité de la vis et une portée orientée susceptible de coiffer une partie des filets de la vis et des griffes de retenue externes orientées vers l'autre face de la paroi et réparties à l'extrémité de chacune des languettes.In accordance with the invention, the device consists of a
a face of spacer oriented towards / the wall and carries the orifice for the passage of the screw, a series of elastic tabs distributed at the periphery, which have a smooth internal engagement surface of the end of the screw and an oriented bearing susceptible to cover a part of the threads of the screw and of the external retaining claws oriented towards the other face of the wall and distributed at the end of each of the tabs.
D'autres caractéristiques de l'invention ressortiront de la description qui va suivre en référence au dessin annexé dans lequel - la figure 1 est une vue partielle à une plus grande échelle montant une section du plancher au cours du montage de la glissière portant l vis de fixation.Other characteristics of the invention will emerge from the description which follows with reference to the appended drawing in which - Figure 1 is a partial view on a larger scale mounting a section of the floor during assembly of the slide bearing the screw of fixation.
- la figure 2 représente la section du plancher au cours du vissage de l'écrou.- Figure 2 shows the section of the floor during the screwing of the nut.
- la figure 3 est une vue de dessus du dispositif de retenue.- Figure 3 is a top view of the retainer.
La figure 1 montre le dispositif monté sur la paroi du véhicule formant plancher 10 localement rigidifié par son renfort 11. Le plancher 10 est percé par l'orifice 12 du passage d'une vis 13 dont on perçoit la queue à la figure 1 avant qu'elle ne soit mise en place comme cela est montré à la figure 2. FIG. 1 shows the device mounted on the wall of the vehicle forming the floor 10 locally stiffened by its reinforcement 11. The floor 10 is pierced by the orifice 12 through the passage of a screw 13, the tail of which can be seen in FIG. 1 before 'it is not set up as shown in Figure 2.
Le plancher 10 est recouvert d'un tapis 14 muni de l'ouverture 15 de passage du dispositif de retenue axiale 20 dont la structure apparait à l'examen des figures.The floor 10 is covered with a mat 14 provided with the opening 15 for passage of the axial retaining device 20, the structure of which appears on examination of the figures.
Le dispositif de retenue axiale 20 de la vis 13 est constitué par une entretoise 21 qui repose sur la face supérieure du plancher, de configuration générale circulaire sur laquelle vient reposer la face inférieure de la glissière inférieure 16 munie d'un perçage 17 traversé par la vis 13. Selon un mode de montage connu la tête 18 de la vis 13 est soudée sur l'ame 19 de la glissière 16 si bien que la queue de la vis et lfensemble de la glissière est fixé sur le plancher 10.The axial retaining device 20 of the screw 13 is constituted by a spacer 21 which rests on the upper face of the floor, of generally circular configuration on which rests the lower face of the lower slide 16 provided with a hole 17 through which the screw 13. According to a known mounting method, the head 18 of the screw 13 is welded to the core 19 of the slide 16 so that the tail of the screw and the whole of the slide is fixed to the floor 10.
L'entretoise 21 orientée vers une face du plancher 10 traverse l'ouverture 15 du tapis 14 et repose sur le plancher 10 et stop- pose de la sorte à l'écrasement' du tapis 14 sous le poids des glissières et du siège non représenté. L'entretoise 21 est munie de l'orifice de passage 22 de la vis 13 qui possède une entrée tronconnique favorable à l'autocentrage de la vis. A la périphérie de l'orifice 22 est répartie une série de languettes élastiques 23 qui possèdent une portée interne lisse 24 d'engagement de la queue de vis et une portée interne crantée 25 susceptible de coiffer des filets de la vis 13.The spacer 21 oriented towards one face of the floor 10 passes through the opening 15 of the mat 14 and rests on the floor 10 and stops in this way the crushing of the mat 14 under the weight of the slides and the seat not shown. . The spacer 21 is provided with the passage orifice 22 of the screw 13 which has a frustoconical inlet favorable to the self-centering of the screw. At the periphery of the orifice 22 is distributed a series of elastic tongues 23 which have a smooth internal surface 24 for engaging the screw shank and a notched internal surface 25 capable of covering the threads of the screw 13.
L'extrémité de chaque languette porte une griffe de retenue externe 26 orientée vers la face inférieure du plancher.The end of each tongue carries an external retaining claw 26 oriented towards the underside of the floor.
Le sommet de la griffe 26 est bordé par une mortaise 27 dont la largeur est légèrement supérieure à I'épaisseur du plancher 10 et de son renfort 11.The top of the claw 26 is bordered by a mortise 27 whose width is slightly greater than the thickness of the floor 10 and its reinforcement 11.
Ainsi que cela est montré à la figure 2 les languettes 23 s'écartent latéralement vers l'extérieur sous l'effet du passage-de la vis puis reviennent partiellement en place Jusqu'à ce que leurs portées crantées 25 viennent coiffer les filets correspondants de la vis 13. As shown in FIG. 2, the tongues 23 deviate laterally outwards under the effect of the passage of the screw and then partially return in place until their notched surfaces 25 come to cover the corresponding threads of screw 13.
Il y a lieu de noter que les griffes 26 au cours de leur écartement immobilisent l'entretoise 21 par rapport à l'orifice 12 du plancher et que l'étendue radiale de chacune des griffes 26 est supérieur à celle des crans dans le but de réaliser à la fois l'immobilisation axiale de l'entretoise 21 par rapport au plancher et l'immobilisation axiale de la vis 13 par rapport à l'entretoise 21.It should be noted that the claws 26 during their spacing immobilize the spacer 21 relative to the orifice 12 of the floor and that the radial extent of each of the claws 26 is greater than that of the notches for the purpose of perform both the axial immobilization of the spacer 21 relative to the floor and the axial immobilization of the screw 13 relative to the spacer 21.
Dans ces conditions l'ensemble des glissières 16 et du siège est positionné par rapport au plancher 10 et autorise la mise en place des écrous de serrage 28 dont l'embase 29 vient coiffer les griffes de retenue 26 sous l'effet de la tête de vissage 30. Under these conditions, all of the slides 16 and of the seat are positioned relative to the floor 10 and authorizes the fitting of the clamping nuts 28, the base 29 of which covers the retaining claws 26 under the effect of the head. screwing 30.
