<p>The hinge joint is in two or more pivoting parts, joining components together. It has fixing portions (6, 7) secured to the components (1, 2) while a further component (8, 9) hinges on each portion. These components are movable between a first position, locking the components (1, 2) so that they cannot hinge in relation to each other, and a second one in which they are free to do so.</p> |
