PCT No. PCT/US94/07924 Sec. 371 Date Jan. 11, 1996 Sec. 102(e) Date Jan. 11, 1996 PCT Filed Jul. 8, 1994 PCT Pub. No. WO95/02168 PCT Pub. Date Jan. 19, 1995A scale for weighing a load, which is made up of a base (12), a weighing platform (34) for supporting the load and a load cell (36, 98) located below the weighing platform so as to alternate between an operational position, in which the weighing platform is supported by the load cell for measuring the weight of the load, and a neutral position, in which the weighing platform is supported by the base member for carrying the load. The scale further includes a contact member (40, 48, 116) located below the weighing platform (34) so as to reversibly come into contact with the load cell so that the load cell alternates between the operational position and the neutral position due to a relative movement between the load cell and the contact member. The scale further includes a mechanism (26, 52, 96, 110) for generating the relative movement.
