In a balance, having a top mounted scale that is protected by a box-like structure (2) consisting of glass, is set on the housing base (1) of the balance. The box-like structure encloses a weighing area (5) on all sides around the balance scale (28) of the housing base (1). The front side of the structure (2), which faces the display and operating console (3), forms a load carrying vertical pane (6) consisting entirely of glass which is connected to a glass back wall (7) by at least one holding and guide track (15, 16) which runs from the upper edge of the front pane to the upper edge of the back pane parallel to the longitudinal axis of the housing, limiting the weighing area (5) at the top. The two side walls of the structure (2) are constructed as all-glass sliding doors (8, 10) which are guided at the bottom in the housing base (1) and at the top as bent side extensions (9, 11) in the associated guide and holding track (15, 16). The side extensions (9, 11) are structural members of the cover of the structure (2) and close and open the weighing area (5) at the top. A bracing member (17) is located for bracing purposes in the area of the back wall (7). This bracket connects the two sides of the housing base (1) in a U-shaped manner and also extends over the slides (8, 10, 12) and the one or two holding and guide tracks (15, 16), additionally fixing the latter in the rear area.
A balance having a top mounted balance scale, a housing base (1) with a display and operating console (3), and a box-like structure (2) connected to the housing (1), the structure encloses a weighing area defined by a front pane, two side walls, a back wall and a top wall, (5) around the balance scale (28) of the housing base (1), the weighing area is enclosed with transparent sheets on the front pane, the top wall, and on both side walls, the sides form sliding doors (8, 10) which can be opened to the weighing area (5) and free the access to the balance scale (28), characterized in that the front pane of the structure (2) forms a load carrying vertical pane (6) which is connected to the back wall (7) of the weighing area (5) by at least one holding and guide track (15, 16) which runs from the front pane's upper edge to the back wall's upper edge, parallel to the longitudinal axis of the box-like structure, the holding and guide track marks the limits of the weighing area (5) at the top, and both side walls of the weighing area (5) are constructed as transparent sliding doors (8, 10) which are guided at their bottoms, and at their tops by bent side extensions (9, 11) in the associated guide and holding track (15, 16) whereby the side extensions (9, 11) are components of the cover of the structure (2) and close and open the weighing area (5) on the side and at the top.
Analytical balance having a top mounted balance scale, a housing base (1), carrying the balance scale (28), having a display and operating console (3), and a box-like structure (2) which surrounds the balance scale (28) in an aerodynamically protective manner and comprises transparent surfaces which comprise lateral and upper sliding doors (8, 10, 12) which make it possible to load the balance scale (28) with material to be weighed from both sides and from above, characterized in that the box-like structure is provided with a front wall, two side walls, a top wall, and a back wall which are formed from transparent material and define a weighing area (5), whereby both the front wall and the back wall form load carrying transparent panes (6, 7) whose upper edges are connected by at least one holding and guide track (15, 15', 15", 16) running parallel to and at a lateral distance from the sides of the structure (2) and that the side, walls are both transparent and form sliding doors (8, 8', 10, 10') which are guided on their lower edges and are provided with a bent extensions (9, 9', 11, 11') bent into the plane of the cover of the structure (2), the free end of which is guided by the associated holding and guide track (15, 16) and closes the weighing area (5) at the top in a transparent manner, and that a bracing bracket (17) extends vertically over the structure in a U-shaped manner near the back wall of the structure (2), whereby the holding and guide track (15, 15', 15", 16) is additionally anchored to this bracing bracket (17), and limits the maximum distance the sliding doors (8, 8' , 10 , 10') can shift to the rear.
