    DESCRIPTION
    IMPROVED PERSIAN
    The proposed invention relates to an improved shutter comprising rotating orientable slats characterized in that the rotation of the slats occurs thanks to the fact that the slats incorporate an axis provided with gear elements, such as a pinion which, when engaged with a zipper, the relative displacement of the slat relative to the zipper, rotates the slat.
    During the operations of raising or lowering the blind, the movement of the body of the slat and the rack is solidary, however, the performance of a series of ties located in the path of the parts that incorporate the rack, can block the descent of these pieces that incorporate the zipper. Once the descent of the parts incorporating the rack has been blocked, the blade continues its descent sufficiently that the engagement or friction between the axis of the blade and the rack causes the blade body to rotate.
    By means of the controlled ascent or descent of the slats it is possible to adjust the degree of inclination of the slats.
    The slat comprises a recess in its sides and some eyelashes or projections that act as a stop.
    The axis of the slat has a free movement along a slot integral to the rack and acts as a guide for said axis.
    BACKGROUND OF THE INVENTION
    Mallorcan type blinds, fixed blinds where the slats, rigid, can be oriented to leave more or less light pass are very common.
    So that this possibility of orientation of the slats can be found in the roller blinds, several solutions have been developed, although none presents the technical solution contained in the present.
    Already in 1964 the patent ES296295 referred to a tilting device for rolling shutters of tilting and adjustable slats where those slats or slats were pivotably joined at their ends to side chains that allowed the tilting of
    5

    said slats and also attached to front chains that transmitted the tilting movement from conductive slats to the rest of the slats driven, the slats or permanent slats being attached to the frontal chains that transmitted the oscillating movement between them.
    More recently, utility model 1038677 also raises the orientation of the slats of a blind based on a series of tensioning elements that relate to each other.
    Also the patent ES2043131 presents a roller blind with adjustable slats where the slats are related to each other by a traction chain and an orientation chain.
    This system of slats related to each other both by traction elements and guidance guidance elements is present, among others, in the patents in ES2162571, ES2153463, ES2196936 although each one provides its concrete solutions that overcome certain problems or add advantages Regarding the above.
    In some patents, such as ES2241458, means are incorporated to automate the guidance of the slats in their opening essentially consisting of additional elements that, in the ascent or descent of the blind, collect a series of extensions of the conducting slats and guide them by modifying the orientation of the same and, for the dependencies between them, the orientation of the others, however, these systems allow the orientation of the slats only when the height of the conductive slat is coincident with such additional guiding elements.
    The closest patent in the state of the art is the Spanish patent ES2397012, also of the applicant referring to a blind system with adjustable slats that he shares with the present that the slats comprise an axis that meshes with a rack where, at a time of lowering of the blind, the piece that comprises the rack, and which also includes ratchets, is stopped by the action of a pair of brakes, while the blade continues its descent in such a way that by gearing or friction of the shaft on the rack , the rotation of the lama occurs. The Spanish patent cited, however, does not solve certain problems such as the execution of the ends of the slats, the alignment stops of the slats, the arrangement and configuration of the ratchets and the ties, the slacks of the rack with respect to the pinon axis to favor the rotation, certain problems of pressure in the rolling of the blind or the entry of light through the areas that contribute to the rotation among others.

    DESCRIPTION OF THE INVENTION
    To solve the exposed problems, an adjustable slat system is proposed whose rotational movement is generated by the relative displacement between the slat and a part comprising a rack with which it engages.
    For this, the slat comprises an axis, preferably eccentric and preferably disposed at a point greater than the longitudinal center of gravity of the slat, which protrudes from the body of the slat at its ends and which comprises, at least at one of such ends, although preferably in both, a pinon suitable for engaging with a piece comprising a zipper in such a way that when the slat moves up or down with respect to the piece comprising the zipper, and being both geared, the blade rotates .
    To return the blade to its vertical position, for example, it will be enough to perform the reverse operation, that is, to cause the slats to rise until they are in a vertical position and, once in that position, unlock the parts that incorporate the rack.
    In a theoretical execution, the release of the pieces that incorporate the zipper, would result in the fall of these by gravity and the consequent verticality of the slats, although this form of execution is not advisable, among other reasons, by the abruptness of the fall, the requirement of a greater force for the unlocking of the pieces that incorporate the zipper and an electronic that allows said alternative.
    In this way, each lama is independent of the others and can be alternated in the same blind slats that rotate and lamas that do not rotate.
    To facilitate controlled rotation and other aspects of the operation of the blind, the improved blind comprises:
    1. At least one plank rotating on a particular axis and comprising:
    to. The body of the lama itself, which in turn includes:
    i. An elongated laminar main body between 20mm and 100mm high.
    5
    10
    fifteen

    25

    35
    ii. A setback at the top of the ends of that laminar body being this setback a maximum of 50% of the height of the slat, preferably between 10% and 40% of its height and preferably between 20% and 30% of its height.
    iii. A lower extension at its ends coincides vertically with the setback, this extension being preferably of a height equal to or less than that of the setback.
    iv. At least one stop at one of its ends, this stop being preferably arranged in the recessing zone.
    v. An axis on which the body of the blade rotates in solidarity and incorporates gear or friction elements that we will call pinon, said axis being eccentric and, preferably located at a point higher than the center of gravity of the blade.
    b. A first chain whose links comprise a hub crossed by the axis whose upward and downward movement is integral with that of the main body of the slat, preferably this hub having a longitudinal recess in its front face and a longitudinal projection in its rear face.
    C. A second chain whose links comprise a piece that has an inner zipper and that houses the end of the slat shaft and a linear ratchet on its outer faces, where:
    i. The clearance between the pinon and the rack is preferably between 3% and 8% of the width of the guide slot, the width of the guide slot being understood as the total width of the housing of the rack piece through which the pinon travels.
    ii. The ratchet has, on at least one of its faces, a series of teeth whose angulation with respect to the horizontal flank where the linear ratchet supports is a maximum of 60 °, preferably between 30 ° and 50 °. In the case that the teeth had an isosceles triangle section, the two non-vertical sides being equal, the horizontal of the flank where the linear ratchet supports coincides with the bisector.
    2. A link braking system of the second chain, comprising:
    to. A U-shaped lane
    b. Elements that immobilize or release the link of the second chain.
    C. Means for varying the position of such elements.

    35
    In a system thus configured, the body of the slat will rotate, by action of the pin on the rack, when the relative displacement of the shaft over the rack occurs.
    During the operations of raising or lowering the blind the body of the slat, the link of the first chain and the link of the second chain have an upward and / or downward movement of solidarity.
    Located in the route of the link of the second chain, coinciding with the ratchet, a series of uneven fittings are located to block the descent of the pieces that incorporate the ratchets.
    These joins will be complementary to the ratchet peaks geometry.
    Once the descent of such pieces has been blocked, the body of the blade may continue to descend slightly, guiding the shaft through the slot in the link in the second chain.
    This descent of the body of the slat and its axis with respect to the link of the second chain causes, by action of the pin on the rack, the rotation of the body of the slat.
    The pinon has on its perimeter a serrated area and another or other geometry complementary to the ends of the guide groove, those areas being preferably flat.
    For the return of the body of the slat to its position perpendicular to the earth's surface, it should proceed to ascend slightly in such a way that again the action of the pinon on the rack again causes the rotation of the body of the blade this time in reverse.
    Once the body of the slat is perpendicular to the earth's surface, the joints, by action of a plate, vary their position and release the ratchet allowing the ascent or descent, in solidarity with the body of the slat and the first and second links .
    On the other hand, the pinon that is at the ends of the axis of the plank perimetrically presents a serrated area and flat areas. These flat areas are of
    5
    10
    fifteen
    twenty
    25

    35
    complementary geometry to the ends of the guide groove and help maintain the pinon fixed at the ends of said guide groove.
    The stop that has been mentioned prevents the blade from rotating in the opposite direction, for example by the action of a foreign force and, at the same time, prevents the filtration of light in certain positions of the blade.
    This stop also favors the winding and unwinding operations of the blind on its upper axis, since it helps keep the slats in position when rolling on itself.
    The anterior longitudinal recess and the posterior longitudinal protrusion of the bushing contribute to the fact that during the winding operations the bushing coinciding with the tongue and groove is interconnected.
    In this way, when said bushing is thicker than the slat, when the blind is rolled on the upper roller, all the pressure of the winding falls on the bushing avoiding the suffering of the slats.
    On the other hand, the tongue and groove contributes to the winding being carried out in an orderly manner avoiding lateral displacements that can generate tensions in the structure of the blind.

    i. An elongated laminar main body (1) of a height of 40mm.
    ii. A setback (3) at the top of its ends being this 10mm setback.
    iii. A lower extension (4) at its ends coinciding vertically with the setback being this extension of 10mm.
    iv. A stop (5) at each end, this stop being disposed in the setback zone (3).
    v. An axis (6) on which the blade body rotates in solidarity and incorporates gear or friction elements that we will call pinon (8), said axis being located at a point higher than the longitudinal center of gravity of the blade, presenting the pinon in its perimeter a serrated zone (20) and two zones of complementary geometry with the ends of the guide groove (21) which in this case are flat
    b. A bushing (9) crossed by the shaft (6) whose upward and downward movement is integral to that of the main body of the slat, this bushing presenting a longitudinal recess (10) in its anterior face and a longitudinal projection (14) in its posterior face being both complementary geometry. The set formed by the hub and the hooks with the upper and / or lower hubs will be called the first chain link.
    C. The end of the shaft and the pinion (8) receiving a rack piece (11) suitable for engaging the pinon (8), said piece being attached to a ratchet (12) referring to the assembly formed by both as a link in the second chain (13 ) , where:

    The union of several slats forms a blind that will be rolled or unrolled on the upper roller when it goes up or down.
    In the position of raising or lowering, the slats that are not wound in the upper roller, are aligned in the same plane and preferably perpendicular to the earth's surface as shown in FIGURE 4, the upward and downward movement of the slats and the links of the first and second chain since the drag of the blind is supported by the bushing while the links of the second chain rest, in that position, on the axis.
    During the up or down operations, the slats, specifically the links of the second chain, run free along the rails (27) of the blind as the joists (15) are separated from their passage.
    In order to proceed with the rotation of the slats, the joints (15) vary their position by pivoting on their axis (19) from which they receive their movement, said axis being associated with a driving force such as an electromagnet.
    Depending on their position, which is determined by the axis (19), the joists (15) can invade the ratchet race by blocking it, or keep away from the ratchet race by leaving it free.
    Due to this variation in the position of the ties, the ratchets remain immobile and also the zipper pieces.
    Despite being immobilized the links of the second chain, both the axes of the slats (6) and the bushings (9) and the slats continue their descent through the rack.
    When the zipper is engaged with the pinion (8), the downward movement of the axis of the blade (6) on the fixed rack causes the axis to rotate and, therefore, of the body of the blade (1).
    In order to return the slats to their initial position, that is to say perpendicular to the earth's surface, they proceed to rise causing the reverse rotation due to pinion engagement.
    Once the axle reaches the upper part of the groove that incorporates the links of the second chain, the joints are made to change position, which is achieved by the action of, for example, a plate that runs along the rail and ascends or descends moved by an electroiman being able to proceed to the ascent or descent of the blind.
    5
    In order to avoid that in the winding operation on the upper roller of the blind, the first and the second chain can be destabilized, a recess is provided in the front part of the bushings as well as a projection in its rear part so that the winding over each other, by tongue and groove, a 10-shaped structure is configured that keeps the rolled shutter in position and also the bushings (9), being thicker than the slats, which take the pressure to roll up the blind avoiding the action of unwanted forces on the slats.
