| 摘要 |
<p>The invention concerns a pivoting or sliding gate leaf (1), comprising a metal frame (2) produced by assembling at least two tubular horizontal cross-members (3), (4) with at least two proximal (5) and distal (6) vertical tubular posts, each of the two cross-members (3), (4) for its assembly to the proximal (4) and distal (5) posts being engaged in an opening provided in the wall (5b) (6b), on the inside of the frame, of the corresponding post (5), (6) and being fixed thereto. Each cross-member (3), (4) is immobilized in the corresponding post (5), (6) by a transverse cotter pin (B) secured to said post (5), (6) and extending therein along the geometrical longitudinal axis thereof or parallel to said axis, said pin (B) running right through said cross-member and being engaged in one or more through bores provided in said cross-member (3, 4).</p> |
