  • Patent number: 4979579
    Abstract: An electronic balance with a housing, a balance scale, a wind guard which at least partially surrounds the balance scale and with a display and control unit approximately in the plane of the balance scale. The display and control unit is mounted to the hosing in a manner that it can pivot around the wind guard about at least one vertical axis. This allows the balance to better adapt to various work positions of the operator. Further possibilities of adaptation result from the weighing-area opening of a rotationally symmetrical wind guard which opening can be adjusted as desired and also from the possibility of laterally shifting the display and control unit and/or from the possibility of rotating it about a vertical axis within the display and control unit and/or from the possibility of tilting it about a horizontal axis.

  • Patent number: 4664207
    Abstract: 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).

  • Patent number: 4153126
    Abstract: A parallel construction, particularly for a top-loading balance with elecmagnetic force compensation, has two essentially identical, preferably trapezoidal, movable guides in parallel horizontal planes. The guides are mounted permanently at one end and connected together by a movable rigid connecting element at the other end. The two guides are displaced relative to one another in their planes at right angles to their axis of rotation.
