Self levelling table for commercial weighing scales - has plate supported by pivoting pegs at centre of each side and central suspended mass

摘要

The plate supporting the balance always horizontal and is especially useful for travelling salesmen. The table contains a plate (2) to support a balance and which can rotate, inside a frame (2), using an axis of rotation -3'). The frame (2) can rotate inside a support (4), using an axis of rotation (5-5') perpendicular to the previous one (3-3'). The support (4) has four legs (6) fitted with cross-bars (7). A rigid rod (8) is fixed perpendicularly in the centre of the plate (1) and has under it a mass ) fixed at its end. This mass (9) is used to maintain the plate ) horizontally. The mass (9) also limits the possible oscillations of the Plate (1) and stabilises the table.
