    摘要： A load cell assembly for an electronic scale may include a substantially flat plate having an outer portion and a load cell aperture defining an inner portion having a deflectable member. A sensor may be disposed on the deflectable member responsive to deflection of the deflectable member. A housing may be configured to engage the outer portion of the load cell and hold the load cell. A foot member may include a bottom portion for contacting the surface upon which the electronic scale is sitting and a top portion including an upwardly depending foot member wall for contacting the inner portion of the load cell and foot member snap fit engagement members configured to engage the inner portion of the load cell, the upwardly depending foot member wall and the foot member snap fit engagement members resisting lateral movement of the foot member relative to the load cell.

    摘要： A low-profile platform scale has a horizontal base, a lower primary U-shaped lever, an upper secondary U-shaped lever, a horizontal platform, and load cell means mounted on the base. The base has a unitary structure including a front pair and a rear pair of modified vertical angle irons connected to the ends of a horizontal shallow rectangular tubing and supporting short inverted channel irons each with one leg shorter than the other, to provide a pair of spaced upstanding portions of the base at the central part of the front and rear margins of the base with a portion of the short flanges and a portion of the long flanges of the pair of channel irons providing mounting means at upper and lower elevations as vertical flat surfaces facing the ends of the scale. These flat surfaces are at two transverse vertical planes. The lower and upper levers are constructed primarily of rectangular tubing connected in a unitary manner with the levers pivotally mounted by flexure plates on these vertical surfaces of the channel irons of the base with the pairs of lever arms of the levers extending in opposite directions to the corner portions of the scale. The primary lever has another rectangular tubing in its unitary construction as an intermediate arm extending opposite direction to its pair of levers. The secondary lever has a short intermediate extension in opposite direction to its pair of lever arms and above the intermediate arm of the primary lever. That extension is connected by a flexible cable to the intermediate arm of the primary lever. The distal end portion of the intermediate arm is connected by a flexible cable to the load cell. The platform has a unitary construction including a horizontal rectangular hollow ring having front and rear portions and end portions, downwardly extending vertical angle irons connected to the ring at its corners, front and rear rods between and connected to the bottom portions of the vertical angle irons, and a pair of tubes at the end portions of the platform between and connected to the bottom portions of the angle irons and extending below the distal portions of the lever arms of the primary and secondary levers. This pair of tubes are connected to the pairs of lever arms of the two levers by flexible cables.
