INDETAILED DESCRIPTION OF THE INVENTION

[0015] With a reference to FIG. 1, the hidden closing door system has a rectangular base coupling (100), a traction system (101), closing control valve (102), an opening valve (102b), an adjustment valve (102c), a driving spring (103), a closing shock absorber piston (104), a nut that centers the axle (105), a gum lock (106), a metal bush (107), a traction guide (or rail) (108).

[0016] With reference to FIG. 2, the hidden closing door system comprehends; a traction arm (109), an opening break system (10), a fixative screw (111).

[0017] With reference to FIG. 6, the hidden closing door system comprehends a rectangular coupling base (100) with two assembly holes on the right (112), two assembly holes on the left (113), a coupling traction axle hole (114), an closing valve control coupling hole (115), an opening valve control coupling hole (116), a valve adjustment coupling hole (117).

[0018] The hidden closing door system is designed to function in doors that have additional strength produced applications due to excessive air flows. When considering this factor in the closing movement of the doors. The driving spring (103) allows the sufficient strength for doors displacement which weight can be up to 65 kgs, which must have a perfect support and movility on their turning point, without showing an excessive resistance to the normal displacement.

[0019] the hidden closing door system design allows itself to be hidden between the door and the frame while the door is in closing position, and with the opened door, the only thing one can see is the arm and the traction rail. The exterior design of the closing door system allows that it can be installed on doors with a 4 cm minimum thickness and a 3 cm frame upper part, and it requires that the door must have a solid structure in the upper part with a 10 cm minimum height.

[0020] The hidden closing door system is designed to allow the third valve to work as a additional hydraulic system in conjunction with the first valve, giving this way a double shock absorber traction system at the moment when the hidden closing door system starts its work. The third and the first valve regulate the displacement of the closing of the door, that is to say it, from the maximum opening angle (110 degrees) to the minimum opening degree of 15 degrees, theses two valves regulate the timing and speed in the door closing while the door is in the previously mentioned opening range.

[0021] within this range, the hidden closing door system has a two shock traction system working together, giving in this form, a bigger resistance.

[0022] The function of the second valve mainly consists in to regulate the closing timing, having said that, in the displacement between the 15 degrees to the zero degree, which allows the activation of the doors security system, and in this way, the door gets locked.
