A portable weighing scale of reduced size is adapted to permit the weighing of a person while standing with one foot on the platform of the scale, the weight being manifested by an indicator dial which is latched in weight-indicating position and which maintains the weight indication after the person being weighed has stepped off of the platform. A linkage which permits a degree of lost motion is interposed between the platform and the indicator dial, so that the platform can return to its normal position while the indicator dial remains in weight-indicating position, where it remains until reset to its zero position by operation of a latch release. The scale is stable and does not tend to tip over, even when a person's weight is concentrated at one corner of the platform. A one-piece base incorporates, at fixed positions, a plurality of knife edges, formed integrally with the base, which supports the levers and beams making up the linkage between the platform and the indicator dial. The integral construction of the base assures accurate location of the knife edges in relation to each other and achieves maximum accuracy of the scale.
A portable weighing scale comprising a base, a weighing platform, forming the entire upper surface of the weighing scale, means for resiliently supporting said platform on said base, said platform having an aperture in its upper surface, a weight-indicating dial supported on said base and operatively connected with said platform for rotating in response to a weight resting on said platform to provide an indication of the magnitude of said weight, said indication being visible through said aperture, latch means for holding said dial in weight-indicating position, and release means for selectively releasing said latch means, whereby said weight-indicating dial can be inspected after said weight is removed from said platform, said release means incorporating a manually operable latch releasing control supported by said base at a position remote from said platform.
