Batheroom scales with balance measuring function

Abstract

Provided is a weighing scale with a balance measurement function, which enables an examinee to place his or her feet on a predetermined position on a mounting plate for positioning. The weighing scale has: more than three weight sensors (1), which are arranged under the mounting plate (71); a calculation mechanism, which calculates and obtains the two-dimensional weight value according to the weight value measured by each weight sensor (1). a position of the center of gravity; and a display mechanism (3), which displays the position of the center of gravity obtained by the calculation means on a coordinate plane (31) for display, wherein, on the upper surface of the mounting plate (71), the recessed setting or protruding A foot positioning unit (9) is provided for positioning the front, rear, left and right of the subject's feet.

Description

technical field [0001] The invention relates to a weighing scale with a balance measuring function capable of measuring and displaying the position of the center of gravity of a subject. Background technique [0002] The scales with a balance measuring function that are now popular can not only measure the body weight but also measure the center of gravity of the subject (for example, refer to Patent Document 1). It is provided with three or more weight sensors and can obtain the position of the center of gravity based on the weight applied to each weight sensor. For example, in the device shown in Patent Document 2, each corner of a roughly triangular-shaped loading plate on which the subject is placed is placed. Weight sensors are installed on the lower side of the body, so the center of gravity of the subject is obtained by calculation based on the output of the weight sensors, and the movement trajectory of the center of gravity is displayed on the coordinate map of the ...

AI Technical Summary

Problems solved by technology

[0005] In the weighing scale with balance measurement function as described above, the subject stands on the loading plate and measures the weight through each weight sensor, and calculates the position of the center of gravity according to the weight value, but if the subject stands on the loading plate If the position of its feet is not positioned on the board, there is a problem that the calculated center of gravity position is different from the real center of gravity position
