Problems solved by technology

[0005] In existing balances, if conduits, hoses or other connections must enter the weighing chamber in a flexible, unfixed manner, a slidable side wall or top cover must remain at least Partially open, since the rigid frame and complex guides do not allow the wall panels to have a separate, easy-to-pass conduit pathway
However, leaving a panel open can lead to erroneous weighing results
[0006] In essence, the known balances have the disadvantage that they do not allow at the same time free, unrestricted passage through the weighing chamber and unhindered viewing of the symmetry pan

Embodiment Construction

[0018] according to figure 1 A balance of the present invention comprises a stationary part having a base 2 comprising the working system part of the balance, a cavity 3 actually comprising the drive mechanism and a weighing chamber 4. The rear wall 9 and the floor 8 of the weighing chamber 4 are formed by fixed parts. The weighing chamber 4 is further enclosed by the side walls 5 , 6 , the front wall 7 and the top cover 12 as an air flow barrier. The bottom plate 8 has an opening for the carriage of the weighing pan 10 to pass through. However, as described in patent application EP 1,195,586 A1, the weighing pan can also be supported by an L-shaped cantilever mounted on a connecting device passing through the rear wall of the weighing chamber. Different designs of the weighing pan and / or features of the weighing chamber described in the references just mentioned are also suitable for the balance described here.

[0019] Balance 1 preferably supports with tripod 22.

Abstract

Scales (1) with a scales area (4) that is delimited by fixed parts (8, 9) as well as sidewalls (5, 6), a front wall (7) and cover (12). At least one of the walls or cover can be used to open and shut the scales area using positioning mechanisms (17, 120). Openings (20) are provided in at least one of the fixed or opening walls for feeding through of supply cables.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 26, 2001, an application number of 01131349.8, and an invention title of "balance with a weighing chamber". technical field [0002] The invention relates to a balance with a weighing chamber adjacent to a fixed part of the balance and closed by at least one side wall, a front wall and a top cover, through a guide, at least the side walls and One of the front walls and / or the top cover can slide to facilitate opening and closing of the weighing chamber. Background technique [0003] A known balance of this type, such as that described in European patent application EP0234008A, has a weighing pan and a weighing chamber via a fixed front glass wall, a rearwardly slidable side wall, a The top cover slides back, and a connector connects the side walls to the top cover, enclosing the scale pan on all sides. The connector is configured so that when the side...
