<p>Two hinge flaps, in the form of profile battens of stable material, extending parallel lengthways, and a hinge strip of elastic material, linking these, make up a hinge batten. The profile battens (1,2) and strip (3) are formed with hook-shaped attachments (6,10) hung into each other. Each of these can bound an accommodating groove (7,9) on one side. The strip is pref. C-sectioned, with the grooves formed between its open longitudinal edges and the interconnecting stem, which may be widened by a covering lip (16), monolithically made with it.</p> |
