Abstract

A chair scale for measuring an individual's weight. The chair scale includes a single cantilever beam load cell connecting the base and the seat assembly of the chair. A display and power module is connected to the cantilever beam load cell and displays the weight of user of the chair scale. The display and power module can be integrated into an armrest of the chair scale or in any other part of the seat assembly of the chair scale.

Abstract

A modular scale in the form of a kit or a system includes a plurality of load sensors, a display unit, and a plurality of electrical communication links for electrically connecting the load sensors to the display unit. The load sensors include connectors, such as jacks, for releasably receiving a complementary plug of a cable. The other end of the cable includes another plug for releasable insertion into a complementary jack of the display unit. One of the load sensors can be a master load sensor for receiving weight data of the other load sensors, referred to as slave load sensors. The master load sensor sums the weight data provided by itself and the slave load sensors, for providing combined weight result data. The scale also includes a rigid case for carrying the various modules of the scale, the case being adapted for use as a weighing platform when opened and supported by the load sensors over a surface.

Abstract

An industrial pallet/scale including a platform for supporting a load, having at least three load sensors positioned between and in mechanical communication with the platform and ground. The platform is free of a sheer plate assembly in order to minimize weight of the platform. Each load sensor provides weight data responsive to a downward force relayed from the platform. A display unit in electrical communication with the at least three load cells displays text in response to the weight data of each load cell. The industrial pallet/scale optionally includes load sensors having protection means for protecting the load cells. The protection means functions as a support for the platform, which bears the load of the platform in a protective position. The protection means prevents a pressure member of the load cell from contacting the ground. In a weighing position, the pressure member is coupled directly to the ground, such that the load cell of the load sensor bears the load of the platform.
