DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] An embodiment shall be presented for a box structure in the form of attic stairs. The attic stairs according to the invention are constructed out of box 1, with concertina ladder 2 at least partially retracted into it in a folded state, box 1 is closed from the bottom by closing hatch 3. The attic stairs box includes back wall 11, side walls 12 and front wall 13. The attic stairs are operated using a drive system which includes actuator 41 powered by electric motor 42. Drive system operation is controlled by a remote control. Electric motor 42 transfers motion to actuator 41 using a transmission. The drive system also features a coupler with coupler cable 43, which runs from the coupler to closing hatch 3 bracket 31. Coupler cable 43 terminates with ferrule 44. Bracket 31 base 311 divides it into two parts, one part is threaded 312 and the second part features bracket opening 313 and cavity 314 for rod 17 hook. Bracket 31 is extracted from the closing hatch socket with nut 315 by screwing it out using rod 17 hook, which is located on bracket cavity 314 constituting its contact surface. This tensions coupler cable 43 and causes drive system decoupling and the attic stairs become disconnected from electric motor 42. Rod 17 hook is removed from bracket 31 cavity 314 and inserted into opening 313. In such a position, closing hatch 3 may be pulled down to unfold the stairs manually. Whereas with the attic stairs operating in automatic mode, they are opened and closed using actuator 41. Drive system actuator 41 includes a piston attached to stairs load bearing beam 5 with step 52. Load bearing beam 5 is seated on load bearing beam assembly bases 51 which in turn are attached to box side walls 12. Load bearing frame 8 is supported by support beam 20 suspended using tie-rods 21 from attic stairs box side walls. The other end of actuator 41 is connected with half-frame lateral stile 71 via a coupling element in the form of hook 45. The half-frame also includes side stiles 72 connected telescopically with stairs load bearing frame 8. The half-frame axis of rotation relative to load bearing frame 8 runs through the aforementioned telescopic connection. Load bearing frame 8 includes an upper stile constituting ladder base 9 with concertina ladder 2 suspended from it. Ladder base assembly bases 10 with bearings on them are attached to box side walls 12. These bearings are inserted into ladder base 9 allowing it to rotate when opening and closing the stairs. There are base clamps 19 used to connect load bearing frame 8 with ladder base 9 by means of bolts at the ends of load bearing frame 8. Ladder connectors 18 are resting against base clamps 19. Whereas closing hatch 3 is suspended from box 1 using top suspension flat bars 14 and bottom suspension flat bars 15. To that end brackets 16 are located on closing hatch 3, which feature telescopically connected closing hatch suspension flat bars. Top suspension flat bars 14 connect the hatch to load bearing beam 5 using angle bars 17 whereas bottom suspension bars 15 connect closing hatch 3 to load bearing frame 8. When unfolding the attic stairs, a signal from controller 43 activated via a remote control is sent to electric motor 42 which starts operating. Electric motor 42 power is transferred via a transmission to actuator 41 rod pushing out its piston. In pushing out the piston, hook 6 presses into half-frame lateral stile 71 causing load bearing frame 8 to rotate and closing hatch 3 to open, and then subsequently the half-frame to rotate around an axis running through the telescopic connection between the half-frame and the load bearing frame. Then concertina ladder 2 is extended and also moved towards closing hatch 3, so that once the attic stairs are unfolded, closing hatch 3 and concertina ladder 2 are not parallel to one another. Closing hatch 3 together with the load bearing frame and closing hatch suspension flat bars form a four-bar linkage.
