ABSTRACT:
A balance with a draft shield enclosing a weighing pan (33) has slidable walls (6, 7, 8) with slide handles (10, 110, 210) to open and close the weighing compartment (2). A connector body (22) serves to couple non-adjoining slidable walls (6, 7, 8) to each other. Besides for pushing the slidable walls open and closed, the slide handles (10, 110, 210) also serve to couple and uncouple the slidable walls, so that more than one wall can be moved simultaneously using only one hand, or a wall can be moved by pushing a handle on the opposite side. The slide handles are configured as pairs of handle elements that are attached either to adjoining walls or to a wall and an adjoining place on the connector body. In the coupled state, the pairs of handle elements are folded or swiveled into each other, working as a single handle, e.g., for two adjoining walls. In the uncoupled state, they move the walls individually.
