DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Embodiments will be presented on a structural element, namely attic stairs, with their stairs ladder segments 11, 12, 13 as the stairs articulated component, and stairs box 2 is their fixed component, whereas closing hatch 8 is the additional articulated component.

[0015] In the first embodiment, the attic stairs hinge is constructed out of assembly hanger 4 mounted on the inside surface of attic stairs box 2. Assembly hanger 4 is attached to an articulated component in the form of first ladder segment 11 via base coupler 5 with top pin 51 and bottom pin 52. The swivel axle of base coupler 5 relative to assembly hanger 4 runs through top pin 51. The hanger includes an arm with race 41 for travelling pin 6 mounted on first attic stairs segment 11. In the attic stairs retracted position, travelling pin 6 is at one end of arch shaped race 41. During unfolding of attic stairs, and thus while lowering the articulated component (downwards), travelling pin 6 moves along race 41 towards its other end, and top pin 51 of base coupler 5 executes a rotational movement together with first ladder segment 11. Travelling pin 6 is at the first end of second coupler 7 of the hinge which is attached in a fixed manner to first segment 11 of the attic stairs. The other end of second coupler 7 is attached to base coupler 5 bottom pin 52. In this manner there is an articulated attachment between first stairs segment 11 and stairs box 2 via the hinge. Attic stairs hatch 8 constitutes an additional articulated component, which may be mounted on box 2, where the said hatch 8 is mounted on the stairs hinge using a pair of additional couplers 91 and 92. Additional couplers 91, 92 make an articulated pair of couplers, attached at one point, whereas one of the couplers is suspended on assembly hanger 4 and the other is suspended on the hatch using bracket 14 with coupling pin 15.

[0016] In the second embodiment, not shown on the illustration, the travelling pin is mounted directly to the first ladder segment without using a second coupler.
