Claims

[Claims for Utility Model Registration] (1) A load measuring mechanism consisting of a fixed frame fixed to a base and a movable frame integrated with the fixed frame via a strain body is carried by the movable frame. In an electronic weighing scale housed in the lower area of a lifting platform with a footrest step, the footrest step is formed in the shape of a trapezoid that follows the shape of a foot that allows the user to stand upright with both feet together, and the footrest step is formed on the bottom side of the trapezoid. An electronic weighing scale characterized in that a triangular display section is integrally provided so that the overall planar shape of the lifting platform is approximately a regular pentagon. (2) The strain gauge is provided with a strain gauge to constitute a weight detection means for converting the applied load into an electric signal, and the movable frame and the fixed frame are extended in a substantially "V" shape when viewed from above. A pair of beam members having substantially the same shape and having side beam portions facing each other are arranged symmetrically in the front and back, with the central beam portions facing each other and a strain-generating body interposed between the opposing central beam portions. ,
2. The electronic weighing scale according to claim 1, wherein the load acting on the lifting platform is transmitted to the strain body via the movable frame. (3) The lifting platform is provided with a pair of pushbutton switches on both sides of the rear corners of the footrest step, and these push button switches have a curved shape that follows the outer surface of the lifting platform, and are attached to the side walls of the lifting platform at the outer ends in the left and right direction. a switch body which is held between the two sides and whose hook formed at the inner end in the left and right direction engages with a hole formed in the side wall of the elevator platform to prevent it from coming off; and a switch body which is interposed between the side wall of the elevator platform and the switch body. and hold the switch body against the outside of the side wall of the elevator platform.
2. The electronic weighing scale according to claim 1, further comprising a plate spring member that enables a swinging motion using a holding portion of the switch body as a fulcrum.
