| 摘要 |
The invention concerns a hinge for the rotary joint between a first (1) and a second plane element (2) comprising a cylindrical pivot (4) integral with the first of said two plane elements and a hollow body (3) integral with the second plane element (2) and having a cylindrical cavity (6) mounted matching with the said cylindrical pivot (4) of the first element (1), said cylindrical pivot (4) is fixed to said first element (1) by means of one or several projecting arms (5) such that its longitudinal axis (h-h) is spaced from the outer edge plane of same first element (1) by a distance (d) equal to the radius R of the outer circular profile of said cylindrical hollow body (3), said first element (1) having at its end a bevel (9) suitably shaped to enable the two assembled elements to pivot freely relative to each other by at least 90 DEG in a predetermined direction (A).
