Abstract: A floor scale for measuring body weight having a scale base, a foot platform, an electronic digital weighing system for producing a digital display indicative of the weight applied to the scale platform, and a power switch for controlling the application of power to the electronic digital display system. A weigh cycle control is provided including a kick bar mounted on the scale base at one side of the scale for movement in a generally horizontal direction and adapted to be actuated by the foot of a person before mounting the foot platform, a momentary contact type switch mounted on the scale base for actuation by the kick bar and a timer operated by the momentary contact switch for maintaining the application of power to the electronic digital weighing system for a preselected time interval sufficient for a weighing operation.

Abstract: A weighing scale apparatus including a base and a scale platform and a plurality of bell cranks pivotally mounted on the base at locations angularly spaced apart about a common center for pivotal movement in planes generally tangent to a circle about the common center. A load summing member is connected to the bell cranks at locations vertically offset from the pivot axes for turning thereby about the common center, and the scale platform is connected ot the bell cranks at locations horizontally offset from the pivot axes of the bell cranks in the same angular direction relative to the common center to apply a turning moment to the load summing member correlative with the load on the scale platform. The turning moment applied to the load summing member is sensed as an indication of the load on the scale platform.

Abstract: A platform type weighing scale including a base and a scale platform and first and second pairs of platform suspensions for mounting the platform on the base at the four corners of a generally rectangular pattern, an elongated load sensing beam supported at spaced points therealong on the base, and first and second transfer means respectively interconnecting the first and second pairs of platform suspensions to the beam at a common point intermediate the spaced beam suspension points to apply a bending load to the beam correlative with the sum of the loads applied to the first and second pairs of platform suspensions, and electrical strain gauge means mounted on the load sensing beam for producing an electrical signal correlative with the bending stress produced in the beam as an indication of the total weight applied to the scale platform.

Abstract: A platform type weighing scale including a base, a scale platform, and a unitary weigh frame having spaced parallel torque members and an elongated bendable load sensing beam extending between and ridgidly attached to the torque members. Four frame suspensions engage the torque members to support the weigh frame on the base and four platform suspensions engage the torque members to support the platform on the weigh frame and apply forces to the first and second torque members correlative with the load on the platform and to produce a bending moment in the beam correlative with the sum of the forces applied to the first and second torque members. Electrical transducer means senses bending of the sensing beam as an indication of the weight applied to the scale platform.
