Abstract
A load cell assembly is used with a scale having a weighing platform, in order to provide a very low clearance above a surface on which the scale is positioned. The load cell assembly has a load cell with first and second arms. A bridge portion of the load cell connects the arms, maintaining them in a substantially parallel relationship, with at least a portion of the second arm having a height that is larger than a height of the first arm and the bridge portion. A fastener attaches the load cell to the weighing platform, on the second arm portion with a larger height. A foot device, attached to the first arm, spaces the load cell above the surface on which the scale is positioned.
Claims20
A load cell assembly for use with a scale having a weighing platform with a low clearance above a surface, the load cell assembly comprising:
- a load cell, comprising a first and a second arm, and a bridge portion that connects the respective arms, maintaining the arms in a substantially parallel relationship, with at least a portion of the second arm having a height that is larger than a height of the first arm and the bridge portion;
- a means for fastening the load cell to the weighing platform, on the second arm portion with a larger height;
- and a means for spacing the load cell above the surface, on the first arm.
A scale having a weighing surface less than one inch above the surface on which the scale is positioned, the scale comprising:
- a weighting platform, an upper surface of which defines the weighing surface;
- a plurality of load cell assemblies arranged around a periphery of the weighing platform;
- and
- each said load cell assembly including a first and a second arm, and a bridge portion that connects the respective arms, maintaining the arms in a substantially parallel relationship, with at least a portion of the second arm having a height that is larger than a height of the first arm and the bridge portion;
- a means for fastening the load cell to the weighing platform, on the second arm portion with a larger height;
- and a means for spacing the load cell above the surface, on the first arm.
A low profile platform scale, comprising in combination:
- a substantially planar platform having an upper loading surface and a lower surface opposite said upper surface;
- a plurality of load cells located beneath said platform and with said lower surface of said platform resting upon each of said plurality of load cells;
- each load cell including a first arm and a second arm joined together by a bridge;
- said first arm of each said load cell including a foot extending below said first arm and adapted to rest upon an underlying surface;
- said second arm of each said load cell having an upper surface with an elevated portion thereof that is higher than highest portions of said bridge and said second arm;
- and
- said lower surface of said platform resting on said elevated portions of said second arms of said plurality of load cells.
