Cantilever Arm for Receiving and Measuring a Variable Load Weight

Abstract

A cantilever arm (1, 20, 25, 40, 50, 60, 70), which can be anchored on one side to an object, has a flat body (11), which comprises a resilient material and is designed to receive a variable load weight (4) and is positioned in operation with a vertically aligned surface, in such a way that in the operating position it has a height (v) limited by an upper (6) and a lower edge region (7) and a horizontal extension (h), which is limited on the one hand by an anchoring side region (2) for anchoring the cantilever arm (1, 20, 25, 40, 50, 60, 70) to the object and on the other hand by a cantilevered side region (8) opposite thereto, wherein the cantilever arm (1, 20, 25, 40, 50, 60, 70) further comprises a force application arrangement designed for supporting the load weight (4), characterized in that the flat body (11) of the cantilever arm (1, 20, 25, 40, 50, 60, 70) forms a deformation opening (10) and a connecting arrangement for a deformation sensor for measuring the deformation of the cantilever arm under a current load weight (4), wherein the deformation opening (10) is formed by the flat body (11), penetrates the flat body and is completely enclosed by the same, wherein all the edge regions of the deformation opening lie in the plane of the flat body (11) and said deformation opening has a horizontal extension (h), limited by the anchoring side region (2) and the cantilevered side region (8), and a vertical extension (v) limited by the upper and lower edge regions, in such a way that it deforms under a respective, current load weight (4) accordingly in a predetermined manner, wherein the force application assembly is formed by the body (11) of the cantilever arm (1, 20, 25, 40, 50, 60, 70), and is designed such that in the operating position of the cantilever arm (1, 20, 25, 40, 50, 60, 70) at least a portion of the load weight (4) is introduced into the cantilevered side region (8), and wherein the connecting arrangement is designed to clamp a deformation sensor between the anchoring side region (2) and the cantilevered side region (8) such that said sensor is operational. The cantilever arm (1, 20, 25, 40, 50, 60, 70) is simple in design, inexpensive to manufacture and allows high-precision measurement of a variable load weight (4) using a deformation sensor (35).
