Document Type and Number:
WIPO Patent Application WO/2022/009266
Kind Code:
A1
Abstract:
Provided is a wind screen (10) for a balance scale (1), the wind screen (10) enabling smooth and reliable weighing by preventing negative impacts due to the flow of air onto a weighing tray (51). The wind screen (10) is provided with an outer wind screen (11) forming a weighing chamber (S), and an inner wind screen (21) disposed on the inner side of the outer wind screen (11) so as to cover the weighing tray (51). The outer wind screen (11) has, on side surfaces thereof, a pair of left and right sliding doors (13, 13) that can open and close. The inner wind screen (21) is configured such that a surface facing one of the sliding doors (13) is open, and the inner wind screen (21) has a shielding wall (28a) below this opening (26). Airflow that is generated when the sliding doors (13) of the outer wind screen (11) are opened and closed moves in the direction of the weighing tray along a floor surface of the outer wind screen (11), but is obstructed by the shielding wall (28a) and does not flow inside the inner wind screen (21).
