Top loading precision balance with a draft protection device comprising a pivotable cover |
摘要 |
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.
