Description

La présente invention concerne une aide au débosselage à froid constituée d'une lampe et d'un support.The present invention relates to a cold dent removal aid consisting of a lamp and a support.

Le débosselage à froid et sans peinture de carrosseries de véhicules consiste à appliquer à l'aide d'un outil une pression sur le revers de la tôle à débosseler.The cold and unpainted dent repair of vehicle bodies consists in applying with the aid of a tool a pressure on the reverse side of the sheet to be debossed.

Le document EP-A-0 666 123 , par exemple, décrit de tels outils et de telles aides au débosselage, ainsi que la méthode de travail idoine.The document EP-A-0 666 123 for example, describes such tools and such aids to dent removal, as well as the appropriate method of work.

L'introduction de ce type d'outillage a constitué une simplification majeure dans le domaine du débosselage. En effet auparavant, le carrossier devait redresser la tôle en utilisant soit un perçage de la tôle, soit en soudant sur la tôle une tige permettant de tirer la bosse, et enfin, terminer par les inévitables étapes de mastic et peinture. Dans le cas de véhicule atteints par de nombreux impacts, comme lors d'un orage de grêlons, il était même nécessaire de découper des pans entiers de carrosserie, pour venir souder des tôles de remplacement.The introduction of this type of tooling has been a major simplification in the field of dent removal. Previously, the bodybuilder had to straighten the sheet using either a drilling of the sheet, or by welding on the sheet a rod to pull the bump, and finally, end with the inevitable stages of putty and paint. In the case of vehicles affected by many impacts, such as during a storm of hailstones, it was even necessary to cut entire body panels to weld replacement plates.

Si l'avantage de la méthode de débosselage sans peinture est indéniable, elle requiert cependant un long apprentissage et une extrême précision du geste. Ce travail est effectué à vue, en positionnant l'oeil à l'opposée d'une lumière rasante afin de discerner la moindre irrégularité de la tôle parmi les irrégularités de structure type peau d'orange de la peinture. Les lampes à tube fluorescent combinés de simples réflecteurs ont jusque là produits des résultats satisfaisants, car le flux lumineux de tels tubes est très uniforme en intensité.If the advantage of the paintless dent removal method is undeniable, it requires a long learning and extreme precision of the gesture. This work is done by sight, positioning the eye to the opposite of a grazing light in order to discern the slightest irregularity of the sheet among the irregularities of structure type orange peel paint. Fluorescent tube lamps combined simple reflectors have so far produced satisfactory results, because the luminous flux of such tubes is very uniform in intensity.

L'objet de la présente invention est de fournir une solution d'une aide au débosselage apportant une bonne uniformité d'éclairage tout en étant mobile et autonome.The object of the present invention is to provide a solution of a dent removal aid providing good uniformity of illumination while being mobile and autonomous.

L'aide au débosselage selon l'invention comprend un support, de préférence un support de fixation amovible sur carrosserie, et une lampe connectée au support, et une source d'énergie électrique autonome, la lampe comprenant une paroi diffuseur comportant des écrans diffuseurs translucides, un miroir à l'opposée de la paroi, une pluralité de LED positionnées adjacentes à la paroi diffuseur, entre les écrans, et entre la paroi diffuseur et le miroir, le flux lumineux des LED étant orienté vers le miroir, de telle sorte que le flux lumineux, après réflexion sur le miroir, traverse les écrans diffuseurs afin d'éclairer la zone à débosseler.The self-bending aid according to the invention comprises a support, preferably a removable mounting bracket on the bodywork, and a lamp connected to the support, and an autonomous source of electrical energy, the lamp comprising a diffuser wall comprising translucent diffuser screens. , a mirror opposite the wall, a plurality of LEDs positioned adjacent to the diffuser wall, between the screens, and between the diffuser wall and the mirror, the luminous flux of the LEDs being directed towards the mirror, so that the luminous flux, after reflection on the mirror, passes through the diffusing screens in order to to illuminate the area to be debossed.

Ainsi les LED, sources lumineuses ponctuelles, peuvent être utilisées pour leur faible consommation et grâce à ce système fournir un éclairage uniforme.Thus LEDs, point light sources, can be used for their low consumption and thanks to this system provide uniform lighting.

Avantageusement, les LED (4) sont fixées au revers de la paroi diffuseur, espacées régulièrement le long d'une ligne centrale (6) de ladite paroi. Les LED peuvent être en une seule rangée, ou plusieurs rangées en quinconce, formant un bandeau central. On choisira de préférence des LED ayant un flux lumineux (5) omnidirectionnel. L'uniformité de l'éclairage du diffuseur dépend directement de l'espacement entre les LED et du chemin lumineux LED - miroir - diffuseur, donc de la distance entre ces éléments. Le miroir (3) est plan et parallèle à ladite paroi, mais pourrait avoir une forme favorisant un flux lumineux (5) sur le diffuseur plus homogène. Avantageusement une bande opaque (6), sombre, par exemple noire, parallèle à la longueur sépare les deux écrans. Elle sert de ligne de mire pour analyser la forme et la profondeur de l'impact et surtout elle sert a repérer la poussée de l'envers de l'outil, pour avoir une précision de poussée. De préférence les bords de la bande, rectilignes, ont un effet de brouillard irisant pour que l'on puisse visualiser la peau d'orange de la peinture.Advantageously, the LEDs (4) are fixed to the back of the diffuser wall, spaced regularly along a central line (6) of said wall. The LEDs can be in a single row, or several staggered rows, forming a central strip. LEDs having an omnidirectional luminous flux (5) are preferably chosen. The uniformity of the diffuser illumination depends directly on the spacing between the LEDs and the LED - mirror - diffuser light path, hence the distance between these elements. The mirror (3) is plane and parallel to said wall, but could have a shape promoting a luminous flux (5) on the diffuser more homogeneous. Advantageously an opaque strip (6), dark, for example black, parallel to the length separates the two screens. It serves as a line of sight to analyze the shape and depth of the impact and especially it is used to identify the thrust of the back of the tool, to have a thrust accuracy. Preferably the edges of the strip, rectilinear, have an iridescent mist effect so that one can visualize the orange peel of the paint.

La paroi diffuseur peut être composée d'une plaque de matériau translucide (2) recouverte d'un cache central opaque (6) à l'endroit ou sont positionnées les diodes, ou au contraire être composée d'un cadre structurel comportant le bras central (6) et servant de support pour deux diffuseurs (2) de part et d'autre du bras. Le matériau translucide du diffuseur est typiquement un altuglas ou polycarbonate ou plastique d'aspect blanc laiteux, de préférence couleur blanc crème diffusant pour que l'on puisse avoir un bon reflet sur toute les teintes de carrosseries du noir profond au blanc vernis, l'avantage de cette teinte étant qu'elle est moins fatigante pour les yeux.The diffuser wall may be composed of a plate of translucent material (2) covered with an opaque central cover (6) at the place where the diodes are positioned, or on the contrary be composed of a structural frame comprising the central arm (6) and serving as support for two diffusers (2) on either side of the arm. The translucent material of the diffuser is typically an altuglas or polycarbonate or milky white-colored plastic, preferably cream-white color diffusing so that we can have a good reflection on all the colors of bodies of deep black to white varnish, the advantage of this shade being that it is less tiring for the eyes.

Un boitier (1) protège LED (4), paroi diffuseur et miroir (3) des poussières et éléments, et fournit une structure pour l'ensemble. L'électronique et la source d'énergie autonome, typiquement une batterie rechargeable, par exemple de type Li-Ion, peuvent être intégrées au boitier (1), ou juxtaposées. Le support typiquement comprendra un tuyau aux multiples articulations (7), qui reste en position par friction entre éléments articulés montés à ajustement serré, et est terminé par une ventouse (8) que l'on fixera sur la carrosserie, la lampe pouvant être positionnée librement. La lampe aura typiquement une longueur d'environ 35 à 100 cm afin d'être adapté au débosselage des petites surfaces ou des grandes surfaces comme les pavillons. La hauteur est d'environ 15 cm.A housing (1) protects LED (4), diffuser wall and mirror (3) of dust and elements, and provides a structure for the assembly. The electronics and the autonomous power source, typically a rechargeable battery, for example of Li-Ion type, can be integrated into the housing (1), or juxtaposed. The support typically will comprise a multi-jointed pipe (7), which remains in frictional position between tightly mounted articulated elements, and is terminated by a suction cup (8) which will be fixed on the body, the lamp can be positioned freely. The lamp will typically have a length of about 35 to 100 cm to be suitable for dent removal of small areas or large areas such as pavilions. The height is about 15 cm.
