Abstract

The fixing clip is for a plastics trim strip fitted to a vehicle bumper. It has an arc shaped strip (20), the free ends of which (11,12) are bent outwards concave. This is to press into the walls (25) of an opening (23) in the support (21). From the end parts webs (13) project which are flexible and grip a tongue (24) of the trim (22) to be fixed. The edge of the webs, in contact with the tongue, have teeth. These webs converge towards each other. The clip has curved side edges.

Description

La présente invention concerne un clip perfectionné de fixation d'un gemment notamment en matière plastique, à une structure de support, apte notamment à fixer une bande extérieure en matière plastique à la barre d'un pare-chocs d'une voiture automobile. The present invention relates to an improved clip for fixing a gment in particular made of plastic, to a support structure, suitable in particular for fixing an external strip of plastic to the bar of a bumper of a motor car.

Le but de la présente invention est celui de proposer un clip permettant de fixer d'une manière facile, rapide et très ferme un élément, notamment en matière plastique, à une structure de support, ce clip devant offrir une forme très Ample et par conséquent un prix de revient économique. The object of the present invention is to provide a clip making it possible to fix an element, in particular plastic, in an easy, quick and very firm manner, to a support structure, this clip having to offer a very wide shape and therefore an economic cost price.

Ce but est atteint par un clip de fixation d'un élément, notamment en matière plastique, à une structure de support, caractérisé par le fait qu'il est constitué par une lamelle en forme d'arc dont les parties terminales libres sont pliées suivant une configuration concave vers l'extérieur pour accrocher par encliquetage les parois d'une lumière de la structure de support, tandis qu'à partir de ces parties terminales se développent vers l'intérieur deux ailettes plastique ment flexibles, aptes å saisir et à retenir une languette de ltéldment destiné à etre fixé à la structure de support. This object is achieved by a clip for fixing an element, in particular made of plastic, to a support structure, characterized in that it is constituted by an arc-shaped lamella whose free terminal parts are folded according to an outwardly concave configuration for snap-fastening the walls of a lumen of the support structure, while from these end portions two internally flexible plastic fins develop, capable of gripping and retaining a tab of the element intended to be fixed to the support structure.

D'autres caractéristiques et avantages ressortiront clairement à la lecture de la description qui va suivre d'une forme de réalisation de l'invention, donnée ici à titre d'exemple non limitatif, en regard des dessins annexés. Other characteristics and advantages will emerge clearly on reading the following description of an embodiment of the invention, given here by way of nonlimiting example, with reference to the appended drawings.

La figure 1 représente une vue en élévation d'un clip selon l'invention. Figure 1 shows an elevational view of a clip according to the invention.

La figure 2 représente une vue suivant la flèche F du clip de la figure 1. FIG. 2 represents a view along arrow F of the clip of FIG. 1.

La figure 3 représente une vue en perspective et en éclatd qui montre le mode de fixation d'un élément en matière plastique à une structure de support à l'aide du clip selon l'invention. FIG. 3 represents a perspective and exploded view which shows the method of fixing a plastic element to a support structure using the clip according to the invention.

La figure 4 représente une vue en coupe trans
versale partielle des composants de la figure 3 assemblés entre eux.
Figure 4 shows a trans sectional view
partial versal of the components of FIG. 3 assembled together.

Le clip représenté, désigné dans son ensemble par la référence 10, est essentiellement constitué par une lamelle métallique en forme d'arc présentant des parties terminales libres 11 et 12 pliées suivant une configuration concave vers l'extErieur, i partir desquelles se développent vers 11 intérieur deux ailettes 13 et 14 qui convergent l'une vers l'autre. The clip shown, designated as a whole by the reference 10, is essentially constituted by a metal strip in the shape of an arc having free end portions 11 and 12 bent in a concave configuration towards the outside, from which develop towards 11 inside two fins 13 and 14 which converge towards one another.

Ladite lamelle est dépourvue de sa partie centrale, de sorte que des parties terminales 11 et 12 sont relides par deux bandes latérales 17 et 18 recourbées. La configuration concave des parties 11 et 12 est obtenue en prévoyant entre celles-ci et lesdites bandes des portions de raccordement 19 et 20 et en pliant en
L des parties succestves de ces portions de raccordement.
Said lamella is devoid of its central part, so that end parts 11 and 12 are joined by two side bands 17 and 18 curved. The concave configuration of the parts 11 and 12 is obtained by providing between them and said strips of the connection portions 19 and 20 and by folding in
L of the succest parts of these connecting portions.

Par ailleurs, les ailettes 13 et 14 sont dotées de bords dentelés respectivement 15 et 16.Furthermore, the fins 13 and 14 are provided with serrated edges 15 and 16 respectively.

La figure 3 illustre une application pratique du clip 10 selon la présente invention. A part le clip, sur cette figure sont représentés partiellement une barre 21 d'un pare-chocs de voiture automobile et une bande élastique 22 à appliquer sur la barre 21. Cette dernière est dotée de lumières frontales 23, dont une seulement a été représentée. La bande 22 est en revanche dotée de languettes24 disposées en regard des luoeières 23. De même que pour lesdites lumières, une seule desdites languettes a été représentée. FIG. 3 illustrates a practical application of the clip 10 according to the present invention. Apart from the clip, this figure partially shows a bar 21 of a motor vehicle bumper and an elastic band 22 to be applied to the bar 21. The latter is provided with front lights 23, only one of which has been shown. . The strip 22 is on the other hand provided with tongues24 disposed opposite the luoeières 23. As for said lights, only one of said tongues has been shown.

Pour fixer la bande 22 sur la barre 21, on engage tout d'abord un clip 10 dans chaque lumière 23. Ceci est effectué en introduisant à pression, dans la position illustrée sur la figure 3, chaque clip 10 dans la lumière 23 respective. Le clip se comprime d'abord pour pouvoir passer à travers la lumière, de dimension transversale inférieure, pour ensuite s'encliqueter dans la position stable de la figure 4 où ses parties terminales 11 et 12 se trouvent appliquées contre les parois 25 de la lumière 23. Grâce à leur forme, les parties terminales 11 et 12 'accrocher aux parois 25 en ancrant ainsi de matière stable le clip 10 dans la lumière 23.Puis on approche la bande 22 de la barre 21 et on engage les 'languettes 24 dans les lumières 23 correspondantes, de sorte que chaque languette est saisie et retenue par les dents de la paire d'ailettes 13 et 14 (comme montré sur la figure 4) et reste bloquée dans la position illustrée. To fix the strip 22 on the bar 21, a clip 10 is first engaged in each slot 23. This is done by inserting, by pressure, in the position illustrated in FIG. 3, each clip 10 in the respective slot 23. The clip is compressed first to be able to pass through the lumen, of smaller transverse dimension, then to snap into the stable position of FIG. 4 where its end portions 11 and 12 are applied against the walls 25 of the lumen 23. Thanks to their shape, the end portions 11 and 12 'hang on the walls 25 thereby anchoring the clip 10 in stable material in the lumen 23. Then approach the strip 22 of the bar 21 and engage the' tongues 24 in the corresponding slots 23, so that each tongue is grasped and retained by the teeth of the pair of fins 13 and 14 (as shown in FIG. 4) and remains locked in the position illustrated.

De cette manière, la bande 22 est et demeure fermement assujettie à la barre 21. In this way, the strip 22 is and remains firmly secured to the bar 21.

A la lumière de la description qui précède, on peut facilement comprendre que les opérations de fixation sont sioeples et rapides t, naturellement, ceci vaut également pour l'éventuelle dépose de la bande 22 de la barre 21. Par ailleurs, cette fixation est effectuée au moyen d'un clip de fabrication très simple et par conséquent d'un prix de revient économique. In the light of the above description, it can easily be understood that the fixing operations are sioeples and rapid t, of course, this also applies to the possible removal of the strip 22 from the bar 21. Furthermore, this fixing is carried out by means of a very simple manufacturing clip and therefore of an economic cost price.

Dans le cas d'un pare-chocs pour voitures automobiles, il est possible, grSce au clip 10, d'appliquer de l'extérieur la bande 22 sur la barre da support 21, après que cette barre ait té fixée sur la carrosserie du véhicule au moyen de boulons vissés de l'extérieur, qui seront ensuite inasqués par ladite bande 22.  In the case of a bumper for motor cars, it is possible, thanks to the clip 10, to apply from the outside the strip 22 on the support bar 21, after this bar has been fixed on the body of the vehicle by means of bolts screwed from the outside, which will then be embedded by said strip 22.
