Abstract

Device for indicating the position of the elements of the "three point" hitch described in the main patent, especially for monitoring the vertical movements of the tips of the hooks 31 described in the main patent with respect to the axis which passes through the holes 30 of Figure 4 of this patent and to obtain information on the pivoting of the balance bar 29% with respect to the frame 25 in order for the tractor driver to be able to decide whether or not to alter the settings and to know, at any moment, in what position his hitch is situated, characterised in that the displacement (or angular position) of the tractor is indicated by a potentiometer 5 to which there is connected an electronic circuit which powers a row of diodes 10, 11, 11a, 12, 12a placed either vertically one above the other in order to show up an upwards or downwards movement in vertical planes, or one beside the other in a horizontal line in order to show up a left-to-right or right-to-left movement in horizontal planes, or else in a curved line or in a circle as a function of the representation of the movements of the "three point" hitch device, and in which at least one lit diode indicates the raised position.

Description

L'addition a pour objet un dispositif pour indiquer la position des élements de l'attelage "trois points" décrit dans le brevet principal, afin que le conducteur du tracteur puisse décider d'intervenir ou non sur les réglages et savoir à tout moment dans quelle position se trouve son relevage. The object of the addition is a device for indicating the position of the elements of the "three-point" hitch described in the main patent, so that the tractor driver can decide whether or not to adjust the settings and know at any time in which position is its lift.

D'après l'invention, le déplacement (ou la position angulaire) du tracteur est indiqué par un potentiomètre auquel est relié un circuit électronique qui alimente une rangée de diodes placées soit verticalement les unes au-dessus des autres pour matérialiser un mouvement dans des plans verticaux du bas vers le haut et du haut vers le bas, soit les unes a côté des autres sur une ligne horizontale pour matérialiser un mouvement de la gauche vers la droite ou de la droite vers la gauche dans des plans horizontaux, soit enfin sur une ligne courbe ou sur un cercle en fonction de la représentation des mouvements du dispositif de l'attelage "trois points", et dans lequel au moins une diode allumée indique la position relevée. According to the invention, the displacement (or the angular position) of the tractor is indicated by a potentiometer to which is connected an electronic circuit which feeds a row of diodes placed either vertically one above the other to materialize a movement in vertical planes from bottom to top and top to bottom, either side by side on a horizontal line to materialize a movement from left to right or from right to left in horizontal planes, or finally on a curved line or on a circle depending on the representation of the movements of the device of the "three-point" coupling, and in which at least one lit diode indicates the raised position.

On va maintenant décrire, à titre d'exemple non limitatif, un mode de réalisation de l'invention, avec référence aux dessins annexés sur lesquels:
La figure I est une vue partiellement éclatée du poten tiomètre et de la fiche reliée à la série de diodes mentionnées précédemment.We will now describe, by way of nonlimiting example, an embodiment of the invention, with reference to the appended drawings in which:
Figure I is a partially exploded view of the potentiometer and the plug connected to the series of diodes mentioned above.

La figure 2 est une vue montrant les deux types de diodes qui fournissent les renseignements cherchés. Figure 2 is a view showing the two types of diodes that provide the information sought.

La figure 3 est une vue montrant un point d'un attelage suivant le brevet principal qui peut faire l'objet d'une information fournie suivant l'invention. Figure 3 is a view showing a point of a coupling according to the main patent which can be the subject of information provided according to the invention.

Sur la figure 1, on voit en 1 la partie fixe du potentiomètre utilisé suivant l'invention et qui comprend un boitier de protection 2 contenant une lame - ressort 3 destinée à immobiliser en rotation l'axe 4 d'un potentiomètre 5 tout en permettant un jeu axial. Cet axe est solidaire des pièces en mouvement du tracteur dont la position doit être connue par le conducteur. In FIG. 1, we see at 1 the fixed part of the potentiometer used according to the invention and which comprises a protective case 2 containing a leaf - spring 3 intended to immobilize in rotation the axis 4 of a potentiometer 5 while allowing axial play. This axis is integral with the moving parts of the tractor, the position of which must be known to the driver.

Deux dispositifs d'étanchéité 6 et 7 sont prévus aux extrémités de l'axe de rotation 4. Enfin, on voit en 8 les fiches de prise
DIN.Two sealing devices 6 and 7 are provided at the ends of the axis of rotation 4. Finally, we see at 8 the plugs
DIN.

Sur la figure 2, on voit en 9 l'ensemble placé en face du conducteur et qui contient les diodes de signalisation commandées depuis le potentiomètre de la figure 1. Dans cet exemple, non limitatif, on a prévu un ensemble de vingt-huit diodes de petites dimensions et,à chaque extrémité de cette rangée, une diode de grandes dimension;. Trois diodes 10 de couleur verte sont situées sensiblement au milieu de deux ensembles de diodes rouges, 11 et lia, comprenant respectivement douze et treize diodes, et les deux diodes de grandes dimensions portent les références 12 et 12a. Les diodes rouges indiquent les points dont la position est mauvaise, et les diodes vertes les points dont la position est bonne. In FIG. 2, we see at 9 the assembly placed in front of the conductor and which contains the signaling diodes controlled from the potentiometer in FIG. 1. In this non-limiting example, a set of twenty-eight diodes has been provided. small dimensions and, at each end of this row, a large diode ;. Three green diodes 10 are located substantially in the middle of two sets of red diodes, 11 and 11a, comprising twelve and thirteen diodes respectively, and the two large diodes bear the references 12 and 12a. The red LEDs indicate the points with a bad position, and the green LEDs the points with a good position.

Sur la figure 2, on a représenté une rangée de diodes places verticalement, mais on peut également utiliser une rangée de diodes placées horizontalement. On peut même prévoir plusieurs positions de diodes placées sur des lignes courbes ou sur un cercle, afin de représenter de la meilleure façon possible tous les mouvements du dispositif de l'attelage "trois points". In Figure 2, there is shown a row of diodes placed vertically, but one can also use a row of diodes placed horizontally. It is even possible to provide several positions of diodes placed on curved lines or on a circle, in order to represent in the best possible way all the movements of the device of the "three point" coupling.

Un réglage de position d'un (ou de plusieurs) spot (s) lumineux sur telle ou telle diode de référence est rendu possible par l'intermédiaire d'une curseur ou d'un bouton de réglage non représenté. L'opérateur règle la position de son attelage "trois points" en correspondance avec l'utilisationn7Rel'outil pris en charge par l'attelage faisant l'objet du brevet principal. Le spot lumineux est alors recentré sur l'origine par l'intermédiaire du bouton ou du curseur. A position adjustment of one (or more) light spot (s) on such or such reference diode is made possible by means of a slider or an adjustment button not shown. The operator adjusts the position of his "three point" hitch in correspondence with the use of the tool supported by the hitch which is the subject of the main patent. The light spot is then refocused on the origin using the button or the cursor.

Lorsque la position de l'attelage est modifiée soit au réglage soit en cours de travail, le spot lumineux indique le déplacement, sa valeur et son sens. En effet, le passage d'une diode à l'autre s'effectue en fonction d'un déplacement connu. Le dispositif électronique utilisé, de même que le potentiomètre, est réalisé par des moyens classiques. When the position of the coupling is changed either during adjustment or during work, the light spot indicates the displacement, its value and its direction. Indeed, the passage from one diode to the other takes place according to a known displacement. The electronic device used, as well as the potentiometer, is produced by conventional means.

Sur la figure 3, on voit, à titre d'exemple non limitatif, qu'en plaçant un potentiomètre à un emplacement d'où il peut contrôler les mouvements verticaux des becs des crochets 31 mentionnés dans le brevet principal par rapport à l'axe (non représenté) qui traverse les trous 30 de la figure 4 de ce brevet, on peut obtenir des renseignements sur le pivotement du palonnier 29' par rapport au cadre 25. In FIG. 3, it can be seen, by way of nonlimiting example, that by placing a potentiometer at a location from which it can control the vertical movements of the hooks' noses 31 mentioned in the main patent with respect to the axis (not shown) which passes through the holes 30 in FIG. 4 of this patent, information can be obtained on the pivoting of the lifter 29 'relative to the frame 25.

I1 doit être bien entendu que le mode de réalisation qui vient d'être décrit ne l'a été qu'à titre d'exemple et peut subir de nombreuses modifications sans sortir de l'esprit de l'invention tel que défini par les revendications ci-après.  It should be understood that the embodiment which has just been described has only been given by way of example and can undergo numerous modifications without departing from the spirit of the invention as defined by the claims. below.
