ABSTRACT:
This inventive scale consists of a frame (2), a platform (3) parallel and perpendicular to the frame (2), a load lifter (5) and a level mechanism consisting of at least one arm (1). The lever mechanism transmits the load from the platform (3) to the load lifter (5) and is connected to the frame (2), the platform (3) and the load lifter (5) by means of couplings (10, 13, and 15). The lever mechanism, consisting of at least one arm (1), has a flexible connector at each end and one in the middle (7, 8, and 9). The end connectors (7 and 9) are attached to the platform (3) and the load lifter (5) by means of pins (10 and 15), respectively. The middle connector (8) is attached to the frame (2) by means of two swivel couplings (13).
