Abstract

A balance ( 1 ) has a weighing compartment ( 4 ) that borders on a stationary part ( 8, 9 ) of the balance and is otherwise enclosed by at least one side wall panel ( 5, 6 ), a front wall panel ( 7 ), and a top cover panel ( 12 ). At least one of the panels is slidable by means of a guiding device ( 17, 20 ) to open and close the weighing compartment ( 4 ). The balance ( 1 ) further has a handle ( 13 ) for lifting the balance ( 1 ) off a support surface and/or for carrying the balance ( 1 ).

Claims (11)

1. A balance ( 1 ) comprising a weighing compartment ( 4 ) that borders on a stationary part ( 8 , 9 ) of the balance and is otherwise enclosed by at least one side wall panel ( 5 , 6 ), a front wall panel ( 7 ), and a top cover panel ( 12 ); wherein at least one of said panels is slidable by means of a guiding device ( 17 , 20 ) to open and close the weighing compartment ( 4 ); and further comprising a handle ( 13 ) serving at least one of the purposes of lifting the balance ( 1 ) off a support surface and carrying the balance ( 1 ), wherein the guiding device ( 120 ) of the top cover panel ( 12 ) is at least partially integrated in the handle ( 13 ).

2. The balance ( 1 ) of claim 1 , wherein the handle ( 13 ) is attached to the stationary part ( 8 , 9 ) of the balance ( 1 ).

3. The balance ( 1 ) of claim 1 , wherein the handle ( 13 ) is arranged on top of the balance ( 1 ).

4. The balance ( 1 ) of claim 3 , wherein the handle ( 13 ) is arranged near the top cover panel ( 12 ).

5. The balance ( 1 ) of claim 1 , wherein the handle ( 13 ) is designed and is arranged on the balance ( 1 ) in such a way, that the balance ( 1 ) can be lifted with one hand.

6. The balance ( 1 ) of claim 1 , wherein the handle ( 13 ) is configured as a rail for a guide element ( 14 ) of the guiding device ( 120 ) of the top cover panel ( 12 ).

7. The balance ( 1 ) of claim 6 , wherein the guide element ( 14 ) comprises a vertical body ( 78 ) holding a vertical gear shaft ( 66 ) with an upper gear ( 73 a ) and a lower gear ( 74 a ) and the guiding device comprises a pair of gear racks ( 73 , 74 ) meshing with the gears ( 73 a , 74 a ).

8. The balance ( 1 ) of claim 6 , wherein the guide element ( 14 ) is laterally guided in the guiding device ( 120 ) by a gliding constraint that prevents jamming of the guide element ( 14 ).

9. The balance ( 1 ) of claim 6 , wherein the guide element ( 14 ) is laterally guided in the guiding device ( 120 ) by a rolling constraint that comprises guide rollers ( 75 , 76 ) and provides jamming of the guide element ( 14 ).

10. The balance ( 1 ) of claim 1 , further comprising a holder element ( 15 ) for the top cover panel ( 12 ), wherein the holder element ( 15 ) is integrated in the guiding device, and wherein the holder element has a form-locking closure device that holds and releases the top cover panel ( 12 ) through application of a manual force to at least one of the top cover panel ( 12 ) and the holder element ( 15 ).

11. The balance ( 1 ) of claim 1 , further comprising a clutch lever ( 16 ) arranged on the handle ( 13 ), whereby the top cover panel ( 12 ) can be coupled to and uncoupled from a motorized drive mechanism that serves to move the at least one slidable wall ( 5 , 6 , 12 ).
