Abstract
Dispositif de maintien brachial. Dispositif de maintien brachial constitué d’une flèche (1) et d’un élastique (2) caractérisé en ce que l’effort de maintien résulte d’une part de la flexibilité de la flèche (1) et d’autre part de l’élasticité de l'élastique (2) et en ce que l'élastique (2) coulisse dans un coinceur fixe (9) débrayable lorsque l'opérateur actionne la commande (12). Le dispositif selon l’invention peut être destiné à titre d’exemple non limitatif aux industries employant du personnel en production. Figure pour l’abrégé : FIG 1 Brachial support device. Brachial support device consisting of an arrow (1) and an elastic band (2) characterized in that the holding force results on the one hand from the flexibility of the arrow (1) and on the other hand from the elasticity of the elastic (2) and in that the elastic (2) slides in a fixed stopper (9) which can be disengaged when the operator activates the control (12). The device according to the invention can be intended by way of non-limiting example for industries employing personnel in production. Figure for abstract: FIG 1
Description
La présente invention concerne un dispositif de maintien brachial pour améliorer le confort du travail des opérateurs assis ou debout devant un établi. Les opérateurs en atelier exécutent parfois des mouvements répétitifs pendant plusieurs heures. En fin de journée, la répétition des gestes et le poids des éléments manipulés contribuent à l’accroissement de la fatigue. Plusieurs systèmes ont déjà été imaginés.The present invention relates to a brachial support device for improving the working comfort of operators seated or standing in front of a workbench. Workshop operators sometimes perform repetitive movements for several hours. At the end of the day, the repetition of movements and the weight of the elements handled contribute to increased fatigue. Several systems have already been devised.
L'antériorité montre différentes solutions traitées dans les brevets suivants: DE102005014728-B3, FR2761287-A1, FR2812791-A1,FR3057190-B1,FR3062804-B1,US5501656-A, US5890523-A et US10195734-B2. Les deux brevets soulignés se rapprochent de la présente invention dans la mesure où ce sont des élastiques qui sont employés pour relier les bras de l'opérateur à la potence. Le brevetFR3062804-B1se rapproche également de la présente invention dans la mesure où sa potence rigide est fixée par serrage à l'établi de l'opérateur.The prior art shows different solutions covered in the following patents: DE102005014728-B3, FR2761287-A1, FR2812791-A1, FR3057190-B1 , FR3062804-B1 , US5501656-A, US5890523-A and US10195734-B2. The two underlined patents are close to the present invention insofar as elastics are used to connect the arms of the operator to the stem. Patent FR3062804-B1 is also similar to the present invention insofar as its rigid stem is fixed by clamping to the operator's workbench.
Pour un bon confort de l'opérateur, la force de maintien des bras (et/ou avant-bras) doit varier un minimum sur la hauteur de travail des bras (et/ou avant-bras). Ceci pour permettre à l’opérateur d’une part d'être suffisamment soulagé quand il a les bras en haut de sa zone brachiale de travail et d’autre part de ne pas avoir à forcer sur l’élastique quand il a les bras en bas de sa zone brachiale de travail. Pour cela les lois de la physique d'un élastique imposent que plus un élastique est long au repos, plus la variation de la force de maintien sur une hauteur de travail définie, est faible. Les brevetsFR3057190-B1etFR3062804-Bprésentent l'inconvénient d’assurer la fonction élastique par le seul biais d’un élastique long. Afin de pouvoir réduire la longueur de l’élastique au repos tout en conservant une faible variation de la force de maintien sur la hauteur de travail définie, la présente invention se propose de rendre la potence élastique.For good operator comfort, the holding force of the arms (and/or forearms) must vary a minimum over the working height of the arms (and/or forearms). This is to allow the operator on the one hand to be sufficiently relieved when his arms are above his brachial working area and on the other hand not to have to force the elastic when his arms are in bottom of his brachial working area. For this, the laws of the physics of an elastic impose that the longer an elastic is at rest, the lower the variation in the holding force over a defined working height. Patents FR3057190-B1 and FR3062804-B have the disadvantage of ensuring the elastic function solely by means of a long elastic. In order to be able to reduce the length of the elastic at rest while maintaining a small variation in the holding force over the defined working height, the present invention proposes to make the stem elastic.
Les caractéristiques et avantages de l’invention ressortiront plus clairement à la lecture de la description ci-après, faite en référence aux dessins annexés :The characteristics and advantages of the invention will emerge more clearly on reading the description below, made with reference to the appended drawings:

La flèche (1) muni de l'élastique (2) est caractérisée en ce que l’effort de maintien résulte d’une part de la flexibilité de la flèche (1) et d’autre part de l’élasticité de l'élastique (2). La hauteur H représente la hauteur nécessaire à l'opérateur pour effectuer son travail. La hauteur K représente la hauteur de flexion de la flèche (1). Il est aisé de comprendre par l’homme de l’art que la différence de hauteur entre H et K est assurée par l'élasticité de l'élastique (2).The arrow (1) provided with the elastic (2) is characterized in that the holding force results on the one hand from the flexibility of the arrow (1) and on the other hand from the elasticity of the elastic. (2). The height H represents the height necessary for the operator to carry out his work. The height K represents the bending height of the boom (1). It is easy to understand by those skilled in the art that the difference in height between H and K is ensured by the elasticity of the elastic (2).
