TEMPORARY MECHANICAL ATTACHMENT DEVICE FLEXIBLE IN BENDING AND DESIGNED TO FRACTURE AT A PREDETERMINED TENSILE LOAD, AND METHOD OF MANUFACTURING IT

摘要

23 A unitary construction device for temporarily attaching an object to a support of generally elongate shape along a reference axis, comprises a first part attached to the support and a second part attached to the object and joined to the first part by a coupling portion flexible in bending. This coupling portion comprises a pair of identical axial tangs aligned on a first line transverse to the reference axis and coplanar therewith, flexible parallel to a second line transverse to the reference axis and perpendicular to the first transverse line, and requiring the same energy to fracture in tension parallel to the axis. The coupling portion further comprises at least one pair of first feet attached to the first part, one on each side of the first transverse line and extending axially towards the second part, and at least one pair of second feet attached to the second part and extending axially towards the pair of first feet and separated therefrom by the same predetermined axial distance.
