Precision balance

Terminal

A balance has a balance housing ( ), an operator console ( ), and a pivot arrangement ( ) between the balance housing and the operator console. The pivot arrangement works as a hinge, so that the operator console can be tilted about a transverse horizontal axis (A) that runs parallel to the balance housing. From a normal working position, i.e., projecting forward from the balance housing, the operator console can be folded upward into a rest position. The pivot arrangement has a certain amount of loose play in at least one radial direction. The operator console has a tilt-adjustable part ( ) and a tilt-angle adjusting device ( ) with a secondary transverse tilt axis (B) located in an anterior portion of the operator console. A locking device ( ) serves to secure the tilt-adjustable part in one of at least two selectable tilt-angle positions.

A top-loading precision balance with a draft protection device which includes several walls connected to each other at the edges thereof, and a cover which closes the opening defined at the top of the walls. The cover is fastened through a horizontally extending hinge to one of the walls. The hinge of the cover includes a spring which acts against the direction of movement for closing the cover. The spring mounted in the hinge is a torsion spring which is fixed at both ends thereof. The frame forming the bottom of the draft protection device has on its bottom side a groove into which lugs mounted on the balance housing engage when the draft protection device is placed on the balance housing. A spring is fastened at the groove of the frame under the front side of the draft protection device. The spring engages in a groove of one of the lugs.
