Patent ID: 7559252

Claim:
A force sensor for the measurement of tensile forces in a pulling means comprising: a base body having a first abutment at a first end for fixing an end of a first pulling means, and a second abutment at a second end disposed opposite the first end for fixing an end of a second pulling means, wherein the base body is substantially hollow for receiving the ends of the first and second pulling means, and is bounded by the two mutually oppositely disposed ends in the pulling direction, wherein the first abutment is formed at the first end of the base body by a cover that is releasable from the base body and that is provided with a passage opening for the first pulling means that opens into a hollow space of the base body, wherein an electromechanically operating force measurement sensor is arranged at least in a region of one of the abutments such that a tensile force is transmitted from the end of the first pulling means via the force measurement sensor to the first abutment and from there via the second abutment to the second pulling means, and further wherein the force measurement sensor has a ring-shaped design with an opening that is smaller than the passage opening of the cover and is concentric thereto so that a boundary of the opening of the force measurement sensor projects into an opening region of the passage opening of the cover and represents a direct abutment for the first end of the first pulling means.
