Document Type and Number:
WIPO Patent Application WO2001071202
Kind Code:
A9
Abstract:
A variably amplified load indicating fastener includes a fastener (100) detachably secured to a load indicator via a base member. The fastener (100) has an abutment which is moved by a change in length under an applied load. The load indicator includes a dial plate (16), a needle (24) pivotally supported by the plate (16), a compensating slot (36), a driving slot, an elongated U-shaped element (50) disposed in the direction in which the load is applied when the fastener (100) is in use, and a first reference mark (40a). One side of the U is rigidly attached to the fastener. The closed end of the U is proximate to and movable by the abutment. The other side of the U extends through the compensating slot (36) and the driving slot (26). The needle (24) is operatively coupled to the outer end of said second side. A sleeve with a second reference mark fits over the outer circumference of both the load indicator and the base member.
