MECANISME DE DETECTION DE CHARGE

L'INVENTION CONCERNE LES MECANISMES DE DETECTION DE CHARGE.UN MECANISME DE DETECTION DE CHARGE COMPORTE NOTAMMENT UN BARREAU DE CHARGE VERTICAL 22 UNE PREMIERE PLAQUE A BRAS 46A, UNE SECONDE PLAQUE A BRAS 46B ET DES ELEMENTS DE LIAISON VERTICAUX 43 RELIANT LES EXTREMITES EXTERIEURES DES BRAS DES PREMIERE ET SECONDE PLAQUES, TANDIS QUE LEURS EXTREMITES INTERIEURES SONT ACCOUPLEES AU BARREAU DE CHARGE ET A UN ELEMENT FIXE 49. LORSQU'UNE CHARGE EST APPLIQUEE AU BARREAU, CELUI-CI SE DEPLACE DE FACON RECTILIGNE EN DIRECTION VERTICALE SANS ETRE AFFECTE PAR UNE FORCE S'EXERCANT SUR LUI DANS UNE DIRECTION HORIZONTALE.APPLICATION AUX BALANCES ELECTRONIQUES. A mechanism for detecting a load including a load shaft connected to a pan receiving rod and extending vertically, a first arm plate having integrally formed arms whose one ends are connected to each other, a second arm plate having integrally formed arms whose one ends are connected to each other, and a vertical link connected between the one ends of the arms of first and second arm plates, the other ends of the arms of first and second arm plates being connected to the load shaft and to a fixed member. When a load is applied to the load shaft, the load shaft is moved linearly in the vertical direction without being affected by a force exerted to the load shaft in the horizontal direction.
