Description
La présente invention concerne un perfectionnement apporté<B>à</B> la fabrication et<B>à</B> l'utilisation des pinces de ramassage destinées entre autre<B>à</B> l'entretien, au ramassage de détritus. The present invention relates to an improvement made <B> to </ B> the manufacture and <B> to </ B> the use of pickup tongs intended inter alia <B> to </ B> maintenance, pickup of rubbish.
Dans de telles pinces on utilise généralement un élément de ressort élastique constitué d'un fer plat en acier<B>à</B> ressort cintré en arc de cercle et relié<B>à</B> deux bras rectilignes par une liaison de rivetage. In such clamps is generally used an elastic spring element consisting of a steel flat iron <B> to </ B> curved spring arcuate and connected <B> to </ B> two straight arms by a link riveting.
Avec la méthode de type dite pieces rapportées composée d'un ressort élastique relié<B>à</B> deux bras rectilignes pleins ou tubulaires par rivetage et/ou soudure on obtient un résultat correct mais avec un prix de revient industriel élevé et une main d'oeuvre plus importante notamment pour l'assemblage. With the so-called inserts type method consisting of an elastic spring connected to two straight or tubular straight or tubular arms by riveting and / or welding, a correct result is obtained but with a high industrial cost and more important manpower especially for the assembly.
Or nous avons trouvé, et c' ce fait l'objet de la présente invention, une solution qui permet de résoudre les problèmes posés c'est<B>à</B> dire le gain de poids et l'augmentation du prix de revient tout en permettant une manipulation agréable. Now we have found, and this is the object of the present invention, a solution which makes it possible to solve the problems posed it is to say the weight gain and the increase in the price of returns while allowing a pleasant handling.
D'une manière générale l'invention concerne un perfectionnement apporté aux pinces de ramassage.Le type de fabrication est dit monobloc<B> .</B> Ce dernier est basé sur un élément tubulaire, par exemple un tube d'aluminium qui, par une combinaison particulière de cintrage et d'écrasement localisé suivant un profil déterminé, permet d'obtenir en une seule opération la fonction de ressort élastique et les deux bras rectilignes. In general terms, the invention relates to an improvement made to pick-up grippers. The type of manufacture is said to be monoblock. <B> The latter is based on a tubular element, for example an aluminum tube which, by a particular combination of bending and localized crushing according to a given profile, allows to obtain in a single operation the function of elastic spring and the two straight arms.
Outre l'économie du procédé industriel, le produit final ainsi réalisé ne comporte ni rivet, ni aspérité pouvant blesser la main. La pince est très légère grâce<B>à</B> l'utilisation de tube en lieu et place du fer plein et le guidage dans un seul plan, perpendiculaire au pincement, de deux bras rectilignes garantit une excellente coopération des extrémités. In addition to the economy of the industrial process, the final product thus produced has no rivet or roughness that can hurt the hand. The clamp is very light thanks to the use of the tube in place of the solid iron and the guidance in a single plane, perpendicular to the nip, of two straight arms guarantees excellent cooperation of the ends.
Les deux bras sont complétés par des plaquettes qui forment une pince travaillant avec précision et dont la légèreté et l'aspect totalement lisse et démuni de toute aspérité assure un confort de préhension optimal. The two arms are complemented by plates that form a clamp working precisely and whose lightness and appearance completely smooth and stripped of any roughness ensures optimal grip comfort.
L'invention et les avantages qu'elle apporte seront mieux compris grâce a l'exemple de réalisation donné ci-après<B>'</B> titre indicatif mais non limitatif et qui est illustré par les dessins annexés<B>:</B> La figure<B>1</B> représente la pince vue de côté La figure 2 représente un détail ressort de la pince en perspective La figure<B>3</B> représente un détail des extrémités de la pince et des plaquettes de préhension en perspective. The invention and the advantages it brings will be better understood thanks to the embodiment given below <B> '</ B> indicative but not limiting and which is illustrated by the accompanying drawings <B>: < / B> Figure <B> 1 </ B> shows the clamp seen from the side Figure 2 shows a detail of the spring of the clamp in perspective Figure <B> 3 </ B> shows a detail of the ends of the clamp and grip pads in perspective.
La figure 4 représente un seul plan de flexion de la pince La figure<B>5</B> illustre une forme de réalisation de la pince. Figure 4 shows a single plane of flexion of the clip. Figure <B> 5 </ B> illustrates one embodiment of the clip.

Dans la forme de réalisation illustrée, un bras est coudé (2)<B>à</B> une distance de 200<B>à 300</B> mm de la partie cintrée formant le ressort de façon<B>à</B> obtenir un alignement parallèle des deux bras<B>(3)</B> lorsque la pince est fermée et donc une meilleure géométrie de pincement des objets<B>à</B> ramasser ainsi qu'une meilleure prise en main. In the illustrated embodiment, an arm is bent (2) <B> to </ B> a distance of 200 <B> to 300 </ B> mm from the bent portion forming the spring from <B> to < / B> Obtain a parallel alignment of the two arms <B> (3) </ B> when the clamp is closed and therefore a better pinch geometry of the objects <B> to </ B> pick up as well as a better grip hand.
Dans cette forme de réalisation, chacune des extrémités deux bras<B>(5)</B> est écrasée et percée afin de recevoir, par rivetage notamment, plaquette galbée et formée (4) améliorant la prise de l'objet<B>à</B> ramasser avec la pince. Les flancs de ces plaquettes se touchent lorsque la pince est fermée Les plaquettes sont amovibles et peuvent être remplacées en cas d'usure. Elle peuvent être faites en plastique injecté ou en tôle électro-zinguée par exemple. In this embodiment, each of the ends of two arms <B> (5) </ B> is crushed and pierced in order to receive, by riveting in particular, shaped and shaped plate (4) improving the grip of the object <B> to pick up with the pliers. The flanks of these pads touch when the clamp is closed The pads are removable and can be replaced in case of wear. It can be made of injected plastic or electro-galvanized sheet for example.
Conformément<B>à</B> l'invention, différents profils de cintrage/écrasement peuvent être réalisés afin d'obtenir le guidage parfait des deux bras dans un même plan (2) et donc un positionnement face<B>à</B> face des deux parties servant<B>à</B> pincer<B>(5).</B> According to the invention, different bending / crushing profiles can be realized in order to obtain the perfect guidance of the two arms in the same plane (2) and thus a face positioning <B> to </ B> front of the two parts serving <B> to </ B> pinch <B> (5). </ B>
Un élément limiteur d'ouverture<B>(7)</B> constitué d'un câble traverse les deux bras de la pince et évite ainsi l'ouverture exagérée de la pince. Chaque bras tubulaire est percé afin d'être traversé par le câble aux extrémités duquel sont fixées des boules surmoulées. Le tube utilisé pour la réalisation la pince de ramassage monobloc peut- être de section ronde ou ovale, carrée triangulaire. An opening limiter <B> (7) </ B> consisting of a cable passes through the two arms of the clamp and thus avoids the exaggerated opening of the clamp. Each tubular arm is drilled to be traversed by the cable at the ends of which are fixed overmolded balls. The tube used for producing the monoblock pickup may be of round or oval, square triangular section.
Dans la forme de réalisation illustrée, la section est ronde mais nous pouvons utiliser une autre des sections tubulaires décrites. In the illustrated embodiment, the section is round but we can use another of the described tubular sections.
Dans cette forme de réalisation, section cintrée/roulée/écrasée est plane sur la face extérieure du cerclage et bombée sur la face intérieure. In this embodiment, the bent / rolled / squashed section is flat on the outer face of the hoop and bulged on the inner face.
Cette forme bombée peut également être réalisée sur la base de formes triangulaires ou de profils de différentes sections améliorant l'effet ressort.This curved shape can also be made on the basis of triangular shapes or profiles of different sections improving the spring effect.
Dans une autre forme de réalisation on peut grâce<B>à</B> un cintrage complémentaire<B>(6)</B> combiner la fonction de limitation d'ouverture et la fonction de guidage des deux bras dans un même plan. In another embodiment, complementary bending <B> (6) </ B> can be achieved by combining <b> with </ b> the function of limiting the opening and the guiding function of the two arms in the same plane. .
