<p>The hinge for attaching window casements or wings of doors and keeping them in the selected position consists of simply practicable and applicable components, specifically a first hinge part (1) and a second hinge part (2) which are mutually rotatable around the axis of the bolt (4) by which the aforementioned parts (1, 2) are mutually linked and where between the bolt (4) head (41) and the second element (2) there is at least one spring (5) anticipated while at the same time between the two aforementioned parts (1, 2) there is a friction element (3) inserted which is after the screwing of the bolt (3) into the first part (1) squeezed between the aforementioned parts (1, 2) or according to a predefined force attached against the corresponding fitting surfaces (13, 23) of the specified hinge parts (1, 2). The friction element (3) enclosed by the second hinge part (2) which is on its internal surface (21) featuring a gearing (22), is made as a uniform disc and includes at least two locking elements (31; 311, 311') along the circumference which are adapted to interact with the specified gearing (22) of the second hinge part (2) so that during the rotation of the second hinge part (2) regarding the first hinge part (1) into one direction the corresponding locking element (31; 311, 311') grasps the gearing (22), while upon rotation of the second hinge part (2) regarding the first hinge part (1) into the opposite direction the locking element (31; 311, 311') thanks to is shape and elastic deformation properties deflects at the gearing (22).</p> |
