Bath scale

Bath scales are well known, the common bathroom scale is found in practically every home and typically sits on the floor in the bathroom, in a closet or in a nearby room. The most popular type of scale sold has for many years been the flat, compact and portable bath scale which is both inexpensive and reasonably accurate for measuring variations in ones body weight. The scale typically includes a flat, rectangular base pan over which a load receiving platform is supported. The relatively flat type scales have a platform overlying a weighing mechanism contained within a generally flat housing. The weighing mechanism converts the force produced by a person standing on the platform to a rotation of an output shaft in proportion to the person's weight. This output shaft rotation in conventional bathroom scales moves a scale disc past a window to indicate the weight of the person standing on the scale. In the typical scale, there are four force collecting levers which are pivoted in the corners of the base pan and which are interconnected to deliver the sum of the forces on the platform to a pate which bears downwardly on a helical load spring supported by the pan. There are many bathroom scales in the marketplace which are described as electronic bathroom scales. Many electronic bathroom scales are manufactured using mechanical bathroom scale technology, some manufacturers anchor the end of the mechanical link, which ordinarily attaches to the mechanical dial, and then incorporate a strain gauge assembly to the link.
