发明名称 TAPE MEASURE END HOOK
摘要 A floating end hook for a measuring tape is disclosed which defines two openings for receipt of first and second rivets for attachment of the end hook to the measuring tape. The openings lie on an axis parallel to an inside surface of an abutting member of the end hook. The positioning of the openings allows the force produced when the end hook impacts the measuring tape housing to be approximately evenly distributed between the first and second rivets. A third opening for receipt of a third rivet may be located on the end hook a predetermined distance from the axis on which the other two openings lie. The third opening prevents the end hook from twisting and further ensures that the impacting force is evenly distributed between the first and second rivets.
