The invention starts from the idea that to reach this objective, the rotating slats must be configured to less in the portion that runs along the lateral guides so similar to a conventional slat, so that they can be used conventional traction systems, and therefore compatible with the called Monoblock system.

This task is achieved through the characteristics of a blind arrangement that according to the claim 1, comprises:

Detailed description of an execution example

As can be seen through the figures, the roller blind arrangement according to the invention, designated in general with numerical reference 1, consists of a pair of guide rails 2 installed on the sides of a door or window frame, not shown, or embedded in the vertical hollow walls, two PF fixed blind panels and an adjustable blind panel PO.

PF fixed blind panels are formed by a plurality of fixed slats 3 parallel to each other, whose longitudinal ends 30 run guided in the rails guide sides 2 and which are articulated together by upper and lower lama limbs 31, 32.

It should be noted that for reasons of simplicity of  representation, in the figures the fixed blind panels are they represent with only one lama, but in practice they may be formed by several of them, arranged in the manner described.

The horizontally adjustable blind panel PO is arranged parallel to the aforementioned fixed blind panel PF and consists of a conducting strip 4, a first driven strip 5, and at least a second driven slat 5.

Additionally, slats of transition 7 and 8 for coupling with the respective slats  fixed panel PF and adjustable panel PO as will be explained in detail later.

Thus, a first transition strip 7, is It has a fixed PF panel and an adjustable panel for respective coupling between the lower fixed panel slat upper and conductive slat 4 of the following adjustable panel PO.

In turn, the second transition slats 8 are placed between the PO and PF panels for respective coupling between the bottom driven slat 5 of an adjustable panel and the slat top 3 of the next fixed panel, as will be explained in detail later.

The conductive slat 4 is arranged rotating or orientable around a longitudinal axis 42 and is coupled to a first driven blade 5 rotating around an axis 54 by middle of a drag rod 6 and the remaining slats being driven 5 arranged rotating also on joined axes 54 each other by means of respective 6 connecting rods mounted on 10 lugs arranged in them.

As can be seen especially clearly to  through figures 6 and 7A to 7D, the first transition strip 7 It is adapted to engage articulately at its end upper 70 to the lower extremity 32 of a fixed slat 3 of the fixed blind panel and also adapted to lie with its end lower 71, partly leaning freely against the upper end 40 of the conducting strip 4; in turn, the second lama of transition 8, is adapted to support, in part, freely with its upper end 80 with the lower extremity 51 of a slat driven 5 that lies above and also adapted to mate articulated by its lower end 81 to the upper end 31 of a fixed slat 3 that lies below.

As can also be seen from figures 1 and 2, attached to the guide 2 side rails, two are provided baffle devices 9, known per se, that have a channel of deflection guidance 90 intended to guide guide lugs 43-43 that extend longitudinally from the longitudinal ends of the conductive slat 4.

Making special reference to the Figures 1 to 4 it can be seen that the conductive slat 4 has 44-44 fixed limb portions that run to through the respective lateral guides 2 without the possibility of turning around a longitudinal axis 42 and an intermediate portion 45 that is coupled with the possibility of turning around its axis longitudinally over its fixed limb portions 44. In a manner analogously, the led slats 5, have respective portions of 52-52 fixed limb that run through the respective lateral guides 2 without the possibility of turning around of its longitudinal axis and an intermediate portion 53 that is coupled with the possibility of turning around its axis 54 on its fixed limb portions 52.

It can be seen additionally that the lama of transition 7 has limb portions 72-72 to run through lateral guides 2 and a portion intermediate 73 which has the same longitudinal extension as the intermediate portion 45 of the conductive slat that lies immediately below and resting on it freely. Similarly lama transition 8 has limb portions 82-82 to run through lateral guides 2 and a portion intermediate 83 which has the same longitudinal extension as the intermediate portion 53 of the driven slat 5 that lies immediately above and resting on it freely.

The respective limb portions 44-44 and 52-52 of the conducting strip 4 and of the slats conducted 5, as well as 72-72 and 82-82 respectively of the transition slats 7 and 8 are configured with the same cross section as the fixed slats 3 as can be seen in detail through figures 6 and 7, so that they can be articulated with each other.

The limb portions 44-44 of the conducting strip 4, 52-52 of the slats driven 5, 72-72 of transition strip 7 and 82-82 of the transition strip 8, are joined with their respective intermediate portions, 45, 53, 73 and 83 by means of studs 11.

Additionally, bushings 12 are provided, surrounding the innermost side of the studs 11, to maintain the separation between the limb portions and the intermediate portions of the conductive slats 4, driven 5 and of transition 7 and 8, avoiding displacement and consequent contact between those portions.

As can be seen further, the first  drive rod 6 that connects the conductive blade 4 and the first of the driven slats 5 is rotatably mounted on one side with the guide pin 43 of the conducting strip and on the other to stud 10 threaded to a hole not shown on the driven slat 5. The remaining slats driven 5, are coupled together also by means of respective 6 connecting rods and respective studs threaded 10.

As can also be seen in the figures, for avoid the passage of light and air inside the house, covering the gaps between the blind panels and the wall rear of the guides are arranged a gaskets 13 coupled to the respective side guide rail.

As will be appreciated by people versed in the technique, a blind arrangement as described Previously, it can be easily and easily adapted modifications to a compact window and shutter drawer system thanks to the configuration in the area of the guide rails.

Enough that the object has been described of the invention, it only remains to point out that the embodiments derived from changes in shape, dimensions and the like, as well as those resulting from an application of the above disclosed, they should be considered included in its scope, so that the invention will only be limited by the scope of the following claims.
