Description

Balance du genre pèse-personne
La présente invention a pour objet une balance du genre pèse-personne, ou balance de ménage, de faible encombrement et d'une réalisation très simple.Gender scale
The subject of the present invention is a scale of the weighing scale type, or household balance, of small bulk and of a very simple embodiment.

Le but de la presente invention est de réduire considérablement le coût de fabrication d'une telle balance en limitant au maximum le nombre des pièces la constituant, lesdites pi es pouvant être obtenues, au surplus, par simple emboutissage et estampage d'une feuille de métal ou par moulage de matière plastique. The object of the present invention is to considerably reduce the cost of manufacturing such a scale by limiting as much as possible the number of parts constituting it, said parts being obtainable, moreover, by simple stamping and stamping of a sheet of metal or plastic molding.

Un autre but de l'invention est d'obtenir une balance de très faible encombrement. Another object of the invention is to obtain a very compact footprint.

La balance, selon l'invention, est constituée d'un socle, d'une plaque déformable formant capteur à jauges de contrainte et d'un plateau reposant sur la plaque déformable, recouvrant l'ensemble. Ces éléments peuvent être, par exemple, réalisés en série, à partir d'une tôle ayant deux millimetres d'épaisseur environ. The balance according to the invention consists of a base, a deformable plate forming a strain gauge sensor and a plate resting on the deformable plate, covering the assembly. These elements can, for example, be produced in series, from a sheet having a thickness of approximately two millimeters.

Le procédé de réalisation de la balance selon 1 'in- vention sera mieux compris à la lecture de la description qui suit d'une de ses réalisations préférées et à l'examen des dessins annexés sur lesquels:
La figure I est une vue en perspective explosée d'un pèse-personne selon l'invention montrant les trois éléments le constituant.The method for producing the balance according to the invention will be better understood on reading the following description of one of its preferred embodiments and on examining the appended drawings in which:
Figure I is an exploded perspective view of a scale according to the invention showing the three elements constituting it.

La figure 2 est une vue du pèse-personne de la figure 1 monté. Figure 2 is a view of the scale of Figure 1 mounted.

La figure 3 est une vue en coupe du pèse-personne selon la ligne III-III de la figure 2. Figure 3 is a sectional view of the scale along line III-III of Figure 2.

La figure 4 est une vue en perspective d'une variante de l'élément unique constituant le capteur à jauqes du pèse-personne. Figure 4 is a perspective view of a variant of the single element constituting the gauge sensor of the scale.

A titre d'exemple, on a représenté sur les figures 1 et 2 un pèse-personne selon l'invention réalisé à partir d'unE tôle de deux millimètres environ d'épaisseur, découpée et estampée. Sur la figure 1 montrant en perspective explosée ledit pèse-personne,on voit qu'il est constitue d'un socle rectangulaire 1 formé par une tôle découpée portant à chaque angle, en creux, de petits logements prismatiques 2 destinés à recevoir de petits patins souples 3 qui seront décrits plus loin. Au-dessus du socle 1 est disposé l'élément constituant le capteur à jauges de contrainte 4. By way of example, FIGS. 1 and 2 show a scale according to the invention produced from a sheet of approximately two millimeters thick, cut and stamped. In Figure 1 showing in exploded perspective said scale, we see that it consists of a rectangular base 1 formed by a cut sheet carrying at each angle, hollow, small prismatic housings 2 intended to receive small pads flexible 3 which will be described later. Above the base 1 is arranged the element constituting the strain gauge sensor 4.

Cet élément 4 est réalisé à partir d'une tôle decoupée, de maniere à former un "H" dont les deux branches 4a et 4b sont réunies par une partie centrale 4c amincie en C.n milieu.This element 4 is made from a cut sheet, so as to form an "H" whose two branches 4a and 4b are joined by a central part 4c thinned in C.n middle.

Sur cette partie centrale 4c sont disposées la Jauge de contrainte 5 et ses connexions 6. La jauge de contrainte 5 est constituee, de manière connue, par des résistances disposées sur un substrat collé sur la partie centrale 4.On this central part 4c are arranged the strain gauge 5 and its connections 6. The strain gauge 5 is constituted, in a known manner, by resistors placed on a substrate bonded to the central part 4.

L'élément 4 a une longueur et une largeur légèrement inférieures à celles du socle 1.The element 4 has a length and a width slightly less than that of the base 1.

A chaque extrémité des deux branches 4a - 4b de l'élément 4 sont prévus, sur la face supérieure d'une part deux évidements 7 et 7a et sur la face inférieure d'autre part un évidement 8. Ces évidements sont obtenus par estampage lors de la découpe de l'élément 4. At each end of the two branches 4a - 4b of the element 4 are provided, on the upper face on the one hand two recesses 7 and 7a and on the lower face on the other hand a recess 8. These recesses are obtained by stamping during cutting the element 4.

Au-dessus de l'élément 4 est disposé le plateau 9 du pèse-personne, également réalisé en tôle emboutie. Ce plateau 9 destiné à recevoir la charge à peser, comporte quatre côtés 9a destinés à recouvrir l'ensemble des autres éléments pour les préserver de la poussière. Sur le plateau 9 est prévu un dispositif de lecture électronique 10 indiquant la mesure effectuée, ledit dispositif étant connecte au montage avec la jauge de contrainte 5 et ses connexions F.  Above the element 4 is arranged the plate 9 of the scale, also made of stamped sheet metal. This plate 9 intended to receive the load to be weighed, has four sides 9a intended to cover all of the other elements to protect them from dust. On the plate 9 is provided an electronic reading device 10 indicating the measurement made, said device being connected to the assembly with the strain gauge 5 and its connections F.

Ces divers éléments reposent les uns sur les autres soit de manière classique au moyen de couteaux métalliques, soit au moyen de patins souples 3 réalisés en caoutchouc ou en matière synthétique comme dans l'exemple repré senté. Ces patins 3 ont une forme parallélépipèdique et des dimensions légèrement inférieures à celles des évidements 2, 7 et 7a. Ces patins 3 sont avantageusement maintenus dans les évidements par un point de colle. These various elements rest on each other either conventionally by means of metal knives, or by means of flexible pads 3 made of rubber or synthetic material as in the example shown. These pads 3 have a parallelepiped shape and dimensions slightly smaller than those of the recesses 2, 7 and 7a. These pads 3 are advantageously held in the recesses by a point of glue.

Sur la figure 3 on a représenté en coupe selon la ligne III-III de la figure 2 l'ensemble des éléments montés. Du fait de la conformation de l'élément 4 et de la disposition des patins 3 on obtient un bras de levier parfait. Bien entendu en disposant les patins 3 dans les logements 7a, on peut faire varier, lors du montage, la sensibilite de la balance. In Figure 3 there is shown in section along line III-III of Figure 2 all of the mounted elements. Due to the shape of the element 4 and the arrangement of the pads 3, a perfect lever arm is obtained. Of course by arranging the pads 3 in the housings 7a, it is possible to vary, during assembly, the sensitivity of the balance.

De maniere connue, l'ensemble des él érne nt s montés est rendu solidaire au moyen de vis à tête prisonnière ou anal je, non représenté puisque sortant du cadre de 1 'in- vention. In known manner, all of the mounted components are made integral by means of captive or anal head screws I, not shown since they leave the scope of the invention.

Dans une variante de l'invention, l'élément unique constituant le capteur à jauges 4 est réalisé, comme repré senté sur la figure 4, à partir d'une tole découpée de ma nière à former un "X" dont les branches 41 sont réunies par une partie centrale 42 portant une jauge de contrainte 5 avec ses connexions 6. A chaque extrémité des branches 41 sont prévus, comme dans la réalisation précédente, des évidements 7, 7a et 8 obtenus par estampage, destinés à coopérer avec des couteaux ou des patins souples. In a variant of the invention, the single element constituting the gauge sensor 4 is produced, as shown in FIG. 4, from a sheet cut out in such a way as to form an "X" whose branches 41 are joined by a central part 42 carrying a strain gauge 5 with its connections 6. At each end of the branches 41 are provided, as in the previous embodiment, recesses 7, 7a and 8 obtained by stamping, intended to cooperate with knives or flexible pads.

L'exemple choisi concerne un pèse-personne réalisé à partir d'une feuille de tôle, mais l'invention s'applique bien évidemment à la réalisation de balances de toute sorte, ou en toute autre matière, notamment en matière plastique moulée, sans sortir du cadre de l'invention. De plus, une telle réalisation permet d'obtenir une balance ou pèsepersonne de faible encombrement et ne dépassant pas un centimètre d'épaisseur.  The example chosen relates to a scale made from a sheet of sheet metal, but the invention obviously applies to the production of scales of all kinds, or any other material, in particular molded plastic, without depart from the scope of the invention. In addition, such an embodiment makes it possible to obtain a small scale or scale that does not exceed one centimeter in thickness.
