摘要： A draft protection device for a balance, which encloses a weighing compartment surrounding a weighing pan, has at least one opening that can be closed by a window. The at least one window has at least two slidable window sections which partially overlap each other in any of their positions. According to the invention, a drive mechanism is provided for the opening and closing of the window, which drive mechanism couples the window sections to each other in such a way that all of the window sections move simultaneously and at different speeds during the opening and closing, wherein a fixed ratio between the respective speeds of the window sections can be predetermined by design.

摘要： A balance (1, 101) has a draft protection device (2) that encloses a weighing compartment surrounding the weighing pan (15). A rear wall (22, 122) delimiting the weighing compartment on one side is made of a material (26) that diffuses the transmitted ambient light. The translucent, light-diffusing material (26) is in particular a frosted glass.
