Abstract

Two mutually crossing, rod-shaped elements (1, 2), for example the shaft of a harrow prong and an associated supporting rod, are clamped together with the aid of an angle-shaped bracket (3) whose one limb (4) engages around the one element (1) while the second limb (5) extends over the second element (2) and, at its free end, can be tightened onto the first element (1) with the aid of a bolt (8). With respect to reducing the material and manufacturing costs, the angle-shaped bracket consists of a relatively thin plate section, in which the second bracket limb (5) has side flanges (13) with flaps (15) at the free end which are bent up such that this limb has a cross-section in the shape of a U. The side flanges and the flaps have convex or oblique edges (14, 16) for tightening against two surfaces of the second element (2), which run at right angles with respect to one another.

Description

Pour accoupler deux éléments en forme de barre qui se croisent l'un l'autre, par exemple le manche d'une dent de herse et une barre de support de cette dent1 il est connu d'utiliser une ferrure angulaire de serrage constituée d'un fer plat de résistance et d'élasticité convenables et dont une branche comporte une ouverture permettant de glisser la ferrure sur un des éléments jusqu'à ce que ladite branche vienne en appui contre un des bords du second élément. Prés du bord opposé dudit second élément, la seconde branche de la ferrure ainsi que le premier élément comportent des trous destinés à recevoir un boulon qui par serrage fournira l'effort nbcessaire pour-accoupler les deux éléments l'un à l'autre. To couple two bar-shaped elements which cross each other, for example the handle of a harrow tooth and a support bar for this tooth1 it is known to use an angular clamping fitting consisting of a flat iron of suitable strength and elasticity and one branch of which has an opening allowing the fitting to slide on one of the elements until said branch comes to bear against one of the edges of the second element. Near the opposite edge of said second element, the second branch of the fitting as well as the first element have holes intended to receive a bolt which by tightening will provide the necessary effort to couple the two elements to each other.

On connait un tel exemple de ferrure par le brevet danois nO 108.324 qui, de plus, précise d'une part que le corps du boulon peut comporter une partie excentrée qui lors de la rotation du boulon viendra se serrer latéralement contre le bord du second élément, d'autre part que la seconde branche de la ferrure présente une forme telle que seule sa partie centraleprend appui sur ledit second élément lorsque le boulon est serre
Ceci-a pour but d'assurer une certaine élasticité aux deux extrémités de la ferrure.We know of such an example of fitting by Danish patent nO 108.324 which, moreover, specifies on the one hand that the body of the bolt can comprise an eccentric part which during the rotation of the bolt will come to tighten laterally against the edge of the second element , on the other hand that the second branch of the fitting has a shape such that only its central part is supported on said second element when the bolt is tightened
This is to ensure a certain elasticity at the two ends of the fitting.

Le maintien de cette élasticité impose des exigences. Maintaining this elasticity places demands.

sévères quant à la qualité de l'acier et l'épaisseur de matériau de la. ferrure, en particulier lorsque celle-ci est utilisée ppur maintenir une dent de herse qui, en cours d'emploi, soumet la ferrure à des contraintes sévères et fortement variables, raison pour laquelle les dépenses aussi bien pour le matériau que pour la fabrication sont relativement élevées.severe with regard to the quality of the steel and the thickness of the material. fitting, in particular when it is used to maintain a harrow tine which, during use, subjects the fitting to severe and highly variable stresses, which is why the expenses for both material and manufacturing are relatively high.

La présente invention a pour but de définir une ferrure qui présente, à l'emploi, les mêmes propriétés que la ferrure connue mais qui peut être fabriquée à un prix notablement inférieur. The object of the present invention is to define a fitting which has, in use, the same properties as the known fitting but which can be manufactured at a significantly lower price.

Partant de l'art ainsi connu, la présente invention concerne une ferrure angulaire à boulon de serrage de deux éléments en forme de barre qui se croisent l'un l'autre, en particulier serrage d'une dent de herse sur une barre de support, une des branches de la ferrure comportant une ouverture d'insertion de l'un des éléments, par exemple le manche de la dent, et formant, en position d'emploi, appui pour l'un des bords du second élément, par exemple la barre de support, l'autre branche de la ferrure comportant un boulon essentiellement parallèle à la première branche et prévu pour être introduit dans un trou dans le premier élément et serrer la seconde branche de la ferrure et, par là même,.le second élément contre le premier élément, la seconde branche de la ferrure présentant une surface convexe d'appui contre le second élément. La ferrure selon la présente invention se différencie des ferrures connues du même genre par le fait qu'elle est constituée par un élément de plaque qui par emboutissage et pliage est conformé pour présenter deux rebords plies situés le long des bords de la seconde branche et donnant ainsi à cette branche une section transversale droite en forme d'U à bords convexes formant ladite surface d'ap pui
Le fait de conformer la seconde branche de la ferrure angulaire de telle manière qu'elle présente une section transversale droite en U donne à cette branche une augmentation notable de la rigidité à la flexion par rapport à sa section, ce qui signifie que l'on peut obtenir la solidité voulue avec une épaisseur de matériau moindre que dans le cas de la ferrure connue.Ceci permet donc d'abord une réduction notable du prix de matériau, mais cela influe aussi favorablement sur le prix de fabrication puisque le travail de découpe ou d'emboutissage et, à plus forte raison, de pliage peut être effectué à meilleur prix et que, de plus, on obtient la convexité de la surface d'appui de la seconde branche de la ferrure ( afin d'obtenir la localisation souhaitée d & l'effort d'appui) pour ainsi dire gratuitement, précisément du fait de la forme convexe de la tranche des bords qui seront ensuite repliés sensiblement perpendiculairement au corps de cette branche de la ferrure.Starting from the art thus known, the present invention relates to an angular fitting with a tightening bolt of two bar-shaped elements which cross each other, in particular tightening of a harrow tooth on a support bar. , one of the branches of the fitting comprising an opening for inserting one of the elements, for example the handle of the tooth, and forming, in the position of use, support for one of the edges of the second element, for example the support bar, the other branch of the fitting comprising a bolt essentially parallel to the first branch and intended to be introduced into a hole in the first element and to tighten the second branch of the fitting and, thereby, the second element against the first element, the second branch of the fitting having a convex surface for bearing against the second element. The fitting according to the present invention differs from known fittings of the same kind by the fact that it is constituted by a plate element which by stamping and folding is shaped to present two folded edges situated along the edges of the second branch and giving thus to this branch a straight U-shaped cross section with convex edges forming said support surface.
The fact of conforming the second branch of the angular fitting so that it has a straight U-shaped cross section gives this branch a noticeable increase in the bending stiffness with respect to its section, which means that one can obtain the desired solidity with a lesser thickness of material than in the case of the known fitting. This therefore firstly allows a significant reduction in the price of material, but this also has a favorable influence on the manufacturing price since the cutting or deep-drawing and, a fortiori, folding can be carried out at a better price and that, moreover, one obtains the convexity of the bearing surface of the second branch of the fitting (in order to obtain the desired localization d & the supporting force) so to speak free of charge, precisely because of the convex shape of the edge edge which will then be folded substantially perpendicular to the body of this branch of the fitting.

On peut aussi obtenir le serrage latéral dudit second élément contre la première branche de la ferrure à meilleur prix qu'en utilisant un boulon excentrique comme mentionné plus haut, précisément en conformant les rebords convexes de telle manière que leurs tranches se prolonnt,en direction de l'extrémité libre de l'autre branche, par des rebords inclinés qui, au fur et à mesure qu'ils s'éloignent du corps de cette branche, divergent légèrement par rapport à la première branche de la ferrure et dont la distance respectivement la plus petite et la plus grande à cette branche de ferrure sont respectivement plus petite et plus grande que la largeur dudit second élément.Ceci permet d'obtenir un blocage latéral automatique lors du serrage du boulon étant donné que ledit second élément se trouvera coincé entre la première branche de ferrure et les rebords inclinés. It is also possible to obtain the lateral tightening of said second element against the first branch of the fitting at a better price than by using an eccentric bolt as mentioned above, precisely by shaping the convex flanges so that their edges extend in the direction of the free end of the other branch, by inclined edges which, as they move away from the body of this branch, diverge slightly with respect to the first branch of the fitting and the distance of which respectively smaller and larger at this fitting branch are respectively smaller and larger than the width of said second element. This makes it possible to obtain an automatic lateral locking when tightening the bolt since said second element will be trapped between the first fitting branch and inclined edges.

L'invention sera mieux comprise à l'aide du complément de description ci-après en regard du dessin annexé dans lequel la figure 1 montre une coupe longitudinale d'une ferrure angulaire pour serrage d'une dent de herse sur une barre de support de cette dent, la figure 2 montrant la ferrure vue de l'extrémité et la figure 3 montrant la forme de la pièce emboutie destinée à bord mer la ferrure. The invention will be better understood with the aid of the additional description below with reference to the appended drawing in which FIG. 1 shows a longitudinal section of an angular fitting for clamping a harrow tooth on a support bar. this tooth, FIG. 2 showing the fitting seen from the end and FIG. 3 showing the shape of the stamped part intended for the seaside the fitting.

Sur le dessin, le repère 1 désigne l'extrémité du manche d'une dent de herse, tandis que le repère 2 désigne une barre de support de cette dent de herse. In the drawing, the mark 1 designates the end of the handle of a harrow tooth, while the mark 2 designates a support bar for this harrow tooth.

Les deux éléments 1 et 2 sont à fixer solidement l'un à l'autre et pour ceci on utilise une ferrure angulaire 3 comportant deux branches 4 et 5 mutuellement perpendiculaires, la première branche comportant une ouverture 6 pour le manche 1, l'autre branche comportant un trou 7 pour un boulon 8 dont la distance à la première branche 4 de la ferrure est légèrement supérieure à la largeur de la barre de support 2. Be boulon 8 passe à travers un trou 9 près de l'extrémité libre du manche 1 et supporte un écrou 10 de serrage contre ce manche. The two elements 1 and 2 are to be fixed firmly to each other and for this one uses an angular fitting 3 comprising two branches 4 and 5 mutually perpendicular, the first branch comprising an opening 6 for the handle 1, the other branch having a hole 7 for a bolt 8 whose distance from the first branch 4 of the fitting is slightly greater than the width of the support bar 2. Be bolt 8 passes through a hole 9 near the free end of the handle 1 and supports a nut 10 for tightening against this handle.

La ferrure angulaire 3 est constituée à partir d'un morceau de plaque que l'on découpe d'abord suivant le profil représenté sur la figure 3 et que l'on plie ensuite suivant les pointillés, c'est-à-dire suivant une ligne 11 entre les deux branches 4 et 5 de ferrure et suivant deux lignes longitudinales 12 entre le corps de la branche 5 de ferrure et deux rebord latéraux 13. Ces rebords présentent une tranche convexe 14 et se prolongent vers l'extrémité libre, c'est-à-dire vers le bas de la figure 3, par des ailes plus larges 15 à bord supérieur 16 lOgèrement incliné. The angular fitting 3 is formed from a piece of plate which is first cut along the profile shown in Figure 3 and then folded along the dotted lines, that is to say according to a line 11 between the two branches 4 and 5 of fitting and along two longitudinal lines 12 between the body of the branch 5 of fitting and two lateral flanges 13. These flanges have a convex edge 14 and extend towards the free end, it that is to say towards the bottom of FIG. 3, by wider wings 15 with an upper edge 16 slightly inclined.

A l'état fini, la branche 5 de la ferrure présente une section droite en U dont les flancs sont constitués par les rebords 13 et les ailes 15. Ces rebords donnent non seulement à cette branche de ferrure une rigidité à la flexion très notablement accrue mais aussi des surfaces bien définies d'appui contre la barre de support 2, d'une part par les tranches convexes 14 des rebords en appui contre la face inférieure du manche, d'autre part par les bords inclinés 16 qui,au serrage de l'écrou 10,tirent la barre de support 2 contre la première branche 4 de la ferrure. On peut éventuellement accroître convenablement la rigidité de cette branche, par exemple en la conformant avec une ou plusieurs nervures longitudinales.  In the finished state, the branch 5 of the fitting has a U-shaped cross section whose flanks are formed by the flanges 13 and the wings 15. These flanges not only give this fitting branch a very markedly increased bending stiffness. but also well-defined surfaces of support against the support bar 2, on the one hand by the convex edges 14 of the flanges bearing against the underside of the handle, on the other hand by the inclined edges 16 which, when tightening the nut 10, pull the support bar 2 against the first branch 4 of the fitting. It is possible, if appropriate, to increase the rigidity of this branch, for example by conforming it with one or more longitudinal ribs.
