Abstract
A laboratory instrument with a housing containing a weighing cell has a working compartment that is connected to the housing. The working compartment has a floor, a top cover, a rear wall, a front wall and two sidewalls. Arranged in the working compartment is a load receiver which is connected to the weighing cell. Also connected to the housing is at least one guiding device which serves to guide a linear movement and simultaneous swivel movement of individual portions of the front wall or the entire front wall.
Claims19
A laboratory instrument having a working compartment with access from three sides thereof when at least partially opened, the instrument comprising:
- a housing that contains a weighing cell and which comprises a floor, a top cover, a front and a rear wall, and a pair of sidewalls that delimit the working compartment, the sidewalls and the front wall each being arranged to slide linearly between a closed position and an open position,
- a load receiver, arranged in the working compartment and connected to the weighing cell;
- and
- at least one guiding device that guides the front wall, as a unit or as a plurality of coupled portions, in an angular swivel movement, as well as the linear sliding movement, between the open and closed positions,
- such that simultaneous at least partial opening of each of the two sidewalls and the front wall provides the access.
A laboratory instrument having a working compartment with access from three sides thereof when at least partially opened, the instrument comprising:
- a housing that contains a weighing cell and which comprises a floor, a top cover, a front and a rear wall, and a pair of sidewalls that delimit the working compartment, the sidewalls and the front wall each being arranged to slide linearly between a closed position and an open position, the rear wall and the floor being wall portions of the housing;
- a load receiver, arranged in the working compartment and connected to the weighing cell;
- and
- at least one guiding device that guides the front wall, which is configured as a plate-shaped rigid unit, in an angular swivel movement, as well as the linear sliding movement, between the open and closed positions, the swivel movement having an angle of swivel that depends upon a linear displacement distance of the front wall from the closed position, each of the at least one guiding devices comprising:
- at least one swivel-pivoted linear guide of the front wall;
- and
- at least one means for guiding, arranged between the front wall and the housing, that controls the swivel movement dependent on a linear displacement distance of the front wall from the closed position,
- such that simultaneous at least partial opening of each of the two sidewalls and the front wall provides the access.
