Description

Domaine technique et état de l'art L'invention concerne un système de sécurité de type chandelle, par exemple, mais pas exclusivement, pour un véhicule automobile. De telles chandelles sont par exemple utilisées pour maintenir un véhicule soulevé en vue de changer une roue. On connaît notamment une chandelle du type comprenant un plateau fixé sur un pied, de longueur souhaitée, éventuellement réglable. Le véhicule est soulevé par un dispositif de levage tel qu'un cric, puis la chandelle est positionnée sous le véhicule, et le cric est enfin retiré. Pour ne pas endommager le véhicule, la chandelle doit être positionnée sous le véhicule seulement dans un petit nombre d'endroits, généralement sous des longerons au voisinage des roues. La résistance mécanique du plancher ou du longeron est renforcée localement à ces endroits pour supporter le poids du véhicule lorsqu'il est soulevé. Malheureusement, ces endroits renforcés sont aussi nécessaires pour positionner le cric de levage, et il n'est pas possible de positionner le cric et la chandelle au même endroit. Description de l'invention L'invention propose un nouveau système de sécurité de type chandelle, qui peut être facilement installé sous un véhicule sans endommager ce dernier. Plus précisément, l'invention propose un système comprenant un plateau amovible destiné à être positionné sous le véhicule et à être soulevé à l'aide d'un dispositif de levage tel qu'un cric, et un support destiné à supporter le plateau lorsque le plateau est à une hauteur souhaitée. Le plateau étant amovible, il peut être positionné directement entre le cric et le véhicule à soulever ; le plateau est ainsi soulevé avec le véhicule, puis le support est positionné sous le plateau avant le retrait du cric. 1 25 Selon un mode de réalisation, le support comprend un élément de réception supporté par au moins un pied, l'élément de réception a une forme générale en U. La forme générale en U de l'élément de réception permet de positionner le support sous le plateau, en présence du dispositif de levage. De plus, une distance entre deux branches du U est choisie inférieure à une dimension du plateau. Ainsi, l'élément de réception peut supporter le plateau. Dans une variante, le support comprend quatre pieds répartis sur un bord extérieur de l'élément de réception. Ceci permet d'obtenir une bonne stabilité de l'ensemble. TECHNICAL FIELD AND STATE OF THE ART The invention relates to a security system of the candle type, for example, but not exclusively, for a motor vehicle. Such candles are for example used to keep a vehicle raised to change a wheel. A candle of the type is particularly known comprising a plate fixed on a foot, of desired length, possibly adjustable. The vehicle is lifted by a lifting device such as a jack, then the candle is positioned under the vehicle, and the jack is finally removed. To avoid damaging the vehicle, the candle must be positioned under the vehicle only in a small number of places, usually under spars in the vicinity of the wheels. The mechanical strength of the floor or spar is locally reinforced at these locations to support the weight of the vehicle when raised. Unfortunately, these reinforced areas are also needed to position the jack, and it is not possible to position the jack and the candle in one place. Description of the invention The invention proposes a new security system of the candle type, which can be easily installed under a vehicle without damaging the latter. More specifically, the invention provides a system comprising a removable tray intended to be positioned under the vehicle and to be lifted using a lifting device such as a jack, and a support for supporting the tray when the tray is at a desired height. The tray being removable, it can be positioned directly between the jack and the vehicle to be lifted; the tray is thus raised with the vehicle, then the support is positioned under the plate before removing the jack. According to one embodiment, the support comprises a receiving element supported by at least one foot, the receiving element has a generally U-shaped shape. The general U-shape of the receiving element makes it possible to position the support under the plate, in the presence of the lifting device. In addition, a distance between two branches of the U is chosen less than one dimension of the plate. Thus, the receiving element can support the tray. In a variant, the support comprises four feet distributed on an outer edge of the receiving element. This makes it possible to obtain good stability of the assembly.

Le ou les pieds peuvent être montés mobiles entre une position de rangement et une position de travail. Les pieds peuvent également être solidarisés deux à deux pour former deux paires de pieds. En position de rangement, les pieds s'étendent dans un plan parallèle à un plan principal de l'élément de réception. Le système selon l'invention peut ainsi être rangé facilement à plat. En position de travail, les pieds s'étendent dans un plan différent. Dans une variante, les pieds s'étendent dans un plan sensiblement perpendiculaire au plan principal de l'élément de réception. Dans une autre variante, les pieds ou les paires de pieds sont articulés en ciseaux. La hauteur du support peut ainsi être réglable. De préférence, le système comprend également un système de verrouillage du ou des pieds en position de travail, pour renforcer la sécurité et la stabilité de l'ensemble. De préférence encore, l'élément de réception comprend un rebord apte à empêcher un déplacement en translation du plateau. Ceci renforce également la sécurité et la stabilité de l'ensemble. Brève description des figures L'invention sera mieux comprise, et d'autres caractéristiques et avantages de l'invention apparaîtront à la lumière de la description qui suit d'un exemple de système de sécurité selon l'invention. Cet exemple est donné à titre non limitatif.The foot or feet can be mounted movable between a storage position and a working position. The feet can also be joined two by two to form two pairs of feet. In the storage position, the feet extend in a plane parallel to a main plane of the receiving element. The system according to the invention can thus be stored easily flat. In working position, the feet extend in a different plane. In a variant, the feet extend in a plane substantially perpendicular to the main plane of the receiving element. In another variant, the feet or the pairs of feet are articulated in scissors. The height of the support can thus be adjustable. Preferably, the system also comprises a locking system of the foot or feet in the working position, to enhance the safety and stability of the assembly. More preferably, the receiving element comprises a flange adapted to prevent translation displacement of the plate. This also enhances the security and stability of the whole. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood, and other features and advantages of the invention will become apparent in the light of the following description of an exemplary security system according to the invention. This example is given as a non-limiting example.

30 La description est à lire en relation avec les dessins annexés dans lesquels : 5 - la figure 1 est une vue en perspective d'un système selon l'invention - la figure 2 montre le plateau positionné sous le véhicule et le support prêt à être positionné sous le plateau, et - la figure 3 est une vue en perspective d'une variante de réalisation Description d'un mode de réalisation de l'invention Un système de sécurité selon l'invention comprend un plateau amovible 10 et un support 20. Le plateau 10 est destiné à être positionné sous le véhicule et à être soulevé à l'aide d'un dispositif de levage tel qu'un cric 30. Le support est destiné 10 à supporter le plateau lorsque le plateau est à une hauteur souhaitée. Pour cela, le support est placé sous le plateau et le véhicule soulevés par le cric, puis le cric est retiré. Dans les exemples représentés, le plateau et le support sont métalliques et sont dimensionnés pour avoir une résistance mécanique adaptée au poids du 15 véhicule à soulever. Pour ne pas endommager le véhicule, une cale 40 (en bois ou en tout autre matériau moins dure que le métal) peut être positionnée sur le plateau, entre le plateau et le véhicule, pour venir en appui sur le véhicule. Dans les exemples représentés, le support 20 comprend un élément de réception 21 supporté par quatre pieds 22a à 22d répartis sur un bord extérieur de 20 l'élément de réception. L'élément de réception 21 a une forme générale en U et une distance entre deux branches du U est choisie inférieure à une dimension du plateau 10. L'élément de réception 21 comprend un rebord 24 apte à empêcher un déplacement en translation du plateau. Dans l'exemple des figures 1, 2, les pieds 21a à 21d sont fixés rigidement au 25 support. Dans l'exemple de la figure 3, les pieds 21a à 21d sont fixés deux à deux, et les deux paires de pieds sont montées mobiles par rapport à l'élément de réception par l'intermédiaire d'une articulation 26 de type charnière. Un système 27a, 27b permet le verrouillage des pieds en position de travail.
