Abstract

Abstract Scale protected against ingress of dust and water in which elements of the scale which are always present in any scale are combined with extremely simple additional mechanical means in order to achieve the desired protection, comprising a measuring system, a frame, at least one foot supporting said frame, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, an annular diaphragm mounted between said foot and said inner edge, said load support enclosing completely said measuring system, said frame and said guiding means.

Claim 3
Dependent Claim 86 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, an annular plate, an annular diaphragm mounted between said foot and said inner edge and secured by said annular plate, said load support enclosing completely said measuring system, said frame and said guiding means.
Claim 4
Dependent Claim 86 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, an annular plate, an annular diaphragm mounted between said foot and said inner edge and secured by said annular plate, said load support enclosing completely said measuring system, said frame and said guiding means.
Claim 5
Dependent Claim 102 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, an oblique groove through said foot, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, an annular plate, a diaphragm mounted between said foot and said inner edge and secured by said annular plate, said load support enclosing completely said measuring system, said frame and said guiding means, a cable through said oblique groove connected to said measuring system.
Claim 6
Dependent Claim 102 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, an oblique groove through said foot, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, an annular plate, a diaphragm mounted between said foot and said inner edge and secured by said annular plate, said load support enclosing completely said measuring system, said frame and said guiding means, a cable through said oblique groove connected to said measuring system.
Claim 7
Dependent Claim 99 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support having a detachable top plate with side rims mounted on side walls, a locking device locking said top plate to said side walls, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, a diaphragm mounted between said foot and said inner edge, said load support enclosing completely said measuring system, said frame and said guiding means.
Claim 8
Dependent Claim 99 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support having a detachable top plate with side rims mounted on side walls, a locking device locking said top plate to said side walls, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, a diaphragm mounted between said foot and said inner edge, said load support enclosing completely said measuring system, said frame and said guiding means.
Claim 9
Dependent Claim 88 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, a diaphragm mounted between said foot and said inner edge, said load support enclosing completely said measuring system, said frame and said guiding means, means for pressure compensation between inside and outside of said load support.
Claim 10
Dependent Claim 88 words
In a scale protected against the ingress of dust and water a measuring system, a frame, at least one foot supporting said frame, a load support, guiding means for parallel and vertical guiding of said load support, at least one opening having an inner edge in said load support for said foot, a diaphragm mounted between said foot and said inner edge, said load support enclosing completely said measuring system, said frame and said guiding means, means for pressure compensation between inside and outside of said load support.
