Weighing scale housing with carrier unit for electronics mounted on guiding tracts for removal from the housing, wherein the carrier also serves as a closure plate for the bottom of the pedestal opening
A weighing scale ( 10 ) has a display/operating unit ( 20 ), a scale platform ( 30 ), an electronic system ( 60 ) for the control of the scale ( 10 ), and a pedestal ( 40 ) that connects the display/operating unit to the scale platform. The pedestal contains a pedestal chamber ( 41 ). The pedestal also has a pedestal opening ( 42 ). A carrier element ( 70 ) is arranged in or at the pedestal chamber. At least parts of the electronic system are arranged on the carrier element, and the parts of the electronic system which are arranged on the carrier element can be at least partially taken out of the pedestal opening for servicing.

a pedestal opening;
a carrier element that is arranged in or at the pedestal chamber, such that at least one portion of the electronic system is arranged on the carrier element, with the at least one portion arranged to be at least partially taken out of the pedestal opening for servicing; and
tracks for guiding the carrier element in the pedestal chamber.
2. The scale of claim 1 , wherein:
the pedestal is of an elongated shape with first and second ends, the display/operating unit arranged at the first end and the scale platform arranged at the second end.
3. The scale of claim 2 , wherein:
the pedestal opening is oriented orthogonal to the lengthwise direction of the pedestal, at the second end thereof.
4. The scale of claim 3 , further comprising:
means for closing the pedestal opening.
5. The scale of claim 4 , wherein:
the means for closing the pedestal opening is a closure plate that also operates as the carrier element.
6. The scale of claim 1 , wherein:
the parts of the electronic system that are arranged on the carrier element are not sensitive to dirt.
7. The scale of claim 1 , wherein:
parts of the electronic system that are sensitive to dirt are arranged in the scale platform or in the display/operating unit.
8. The scale of claim 1 , wherein:
the carrier element is adapted to be slidably seated in the pedestal chamber.
9. The scale of claim 1 , wherein:
the carrier element has outer dimensions that approximately match the internal dimensions of the pedestal chamber.
10. The scale of claim 1 , wherein:
the carrier element has a predominantly flat configuration.
11. The scale of claim 1 , further comprising:
elements for positioning the carrier element in the pedestal chamber, the elements being arranged on two opposite sides of the carrier element.
12. The scale of claim 1 , further comprising:
tracks for guiding the seating of the carrier element in the pedestal chamber.
13. The scale of claim 1 , further comprising:
electrical power supply conductors, adapted for receiving electrical power from a source external to the scale, the electrical conductors being connected to the parts of the electronic system that are arranged on the carrier element.
14. The scale of claim 13 , further comprising:
signal conductors, adapted for transmitting signals between the scale and a device external thereto, the signal conductors being connected to the parts of the electronic system that are arranged on the carrier element.
15. The scale of claim 14 , further comprising:
connector elements, each connector element arranged on the carrier element and serving to connect the an electrical power supply conductor or a signal conductors to a corresponding internal conductor of the scale.
16. The scale of claim 1 , wherein:
the carrier element serves as a closure plate for the pedestal opening.
17. The scale of claim 1 , further comprising:
means for closing the pedestal opening.
18. The scale of claim 17 , wherein:
the means for closing the pedestal opening is a closure plate that also operates as the carrier element.
19. The scale of claim 1 , wherein:
the electronic system comprises a first portion and a second portion, with the first portion arranged on the carrier element and the second portion arranged on at least one of: the scale platform and the display/operating unit.
20. A scale for weighing, comprising:
a display/operating unit;
a scale platform;
an electronic system for controlling the scale; and
a pedestal that connects the display/operating unit to the scale platform, the pedestal comprising:
a pedestal chamber,
a pedestal opening; and
a carrier element that is arranged in or at the pedestal chamber, such that at least one portion of the electronic system is arranged on the carrier element, with the at least one portion arranged to be at least partially taken out of the pedestal opening for servicing, the carrier element configured as a closure plate for closing the pedestal opening.
