Abstract

Digital bathroom scale, comprising a housing composed of a bucket or lower plate and a lid or upper plate, whose lid rests on the weighing transmitter mechanism responsible for activating a digital indicator through the corresponding electronic circuit, said being mechanism constituted by four levers related to each other and with a calibrated spring, against whose action the weight of the body located on the upper plate acts, characterized in that said mechanism of weighing transmission is mechanically related to an electric condenser, constituted by two metal plates parallel and superposed, slightly separated from each other, a fixed upper one, mounted in an electrically insulated manner between two supports fixed to the bottom of the lower tank, and another mobile lower one, also mounted in an electrically isolated manner in an arm that runs above the tank mechanism. Heavy, whose arm is articulated by one of its oars, according to a horizontal axis of rotation, to a support fixed to the bottom of the tank, while at its opposite end it rests on said weighing transmission mechanism, with which it is also connected by a tension spring; the two mentioned plates being electrically connected to the electronic circuit, to which transmits the variations in capacity produced at several the distance between said plates by the displacement suffered by the movable plate, when a weight acts on the transmitting mechanism of the pass.
