Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 86 words
An apparatus for measuring loads with the use of a plurality of measuring points, said measuring points consisting of one load-supporting measuring element being placed at each measuring point, wherein each measuring element comprises an upper fastening element, a lower fastening element and means interjacent thereto for taking up lateral forces acting upon the measuring element, said means comprises a ring of resilient material whereby a central space is provided therein for accommodating a pressure medium consisting of a transducer or a volume of measuring liquid.
Claim 2
Independent Claim 86 words
An apparatus for measuring loads with the use of a plurality of measuring points, said measuring points consisting of one load-supporting measuring element being placed at each measuring point, wherein each measuring element comprises an upper fastening element, a lower fastening element and means interjacent thereto for taking up lateral forces acting upon the measuring element, said means comprises a ring of resilient material whereby a central space is provided therein for accommodating a pressure medium consisting of a transducer or a volume of measuring liquid.
Claim 3
Dependent Claim 77 words
An apparatus as claimed in claim 1, wherein each resilient material in each measuring element is arranged to take up also pressure forces acting upon the measuring element, and has a space the volume of which is reduced as the compression of the measuring element increases as a result of increasing load whereby the load is measurable by summation of the expelled volumes of a pressure medium contained in said spaces in all of the measuring elements.
Claim 4
Dependent Claim 52 words
An apparatus as claimed in claim 1, wherein each measuring element contains an electric transducer which is adapted to produce an electric signal dependent upon the compression of the element, and which is so mounted in the measuring element as not to be loaded by lateral forces acting upon the measuring element.
Claim 5
Dependent Claim 59 words
An apparatus as claimed in claim 1, wherein each measuring element contains a load-supporting pressure-sensitive electric transducer which is adapted to produce an electric signal dependent upon the compression force of the load on said measuring element, and which is so mounted in said measuring element as not to be loaded by lateral forces acting upon the measuring element.
Claim 6
Dependent Claim 34 words
An apparatus as claimed in claim 1, wherein the resilient material in each measuring element is disposed in angular or zigzag-shaped spaces for taking up lateral forces but also pressure forces and shear forces.
Claim 7
Dependent Claim 32 words
An apparatus as claimed in claim 5, wherein each measuring element is made safe at its outer periphery by means of a safety ring in order to permit taking up also pull.
