    The invention relates to a roll-up mechanism of different types of roll-up devices or rotlos, such as roller blinds, screens, roll-down shutters, roll-up gates, fire-resistant roll-up shutters and gates, etc.
    Background of the Invention Rollo's are a type of shield that serves to effectively protect the interior, especially from the sun's rays, but also as an attractive and practical decorative element.
    These roilos can also have an acoustic function, provide safety as fire retardants, can be used! as a screen for projectors and as a light controller.
    The rolios can be divided into inner and outer blinds in terms of arrangement with respect to the shielded area.
    The basis of the roilo winding mechanisms is a winding shaft on which a shielding element, such as a slat armor, slipper or foil, is wound.
    The size of the roll up shaft is dimensioned for the weight of the wrapping screen element and, especially in heavy fabric roller blinds, the deformation of the shaft is critical because it causes undulation of the fabric which is considered a visual detect.
    Shaft size is usually limited by the space available for installation or of the cassette, in which the retractor is hidden.
    The rigidity is mainly determined by its diameter, the maximum deflection can be determined by the formula for the maximum deflection of the free beam with uniform continuous load: 5gi *; where q is the continuous load [N / mm] - given by the weight of the blind plus the weight of the load plus the weight of the axle itself, | is the beam length [mm], Eis de Young's modulus | MPa], J is the axial quadratic moment of inertia of the cross section [mm4}.
    © BE2019 / 5743 Thus, the flexural rigidity of the tubular shafts is determined by the type of material and the cross-sectional characteristics, usually using rolled galvanized steel or extruded aluminum, exceptionally carbon composite.
    In the case of round tubes, the diameter is significantly affected, but less the wall thickness, which mainly increases the weight of the roll-up shaft.
    The diameter of the roll-up shaft is a limiting factor for the maximum width of the blind and for large blinds the shaft can even have a diameter of 160 mm, while for an ordinary fabric blind for windows up to two meters wide, a tube with a diameter of 28 mm is sufficient.
    The result is a high weight of the whole system and the need to increase the dimensions of all related components.
    The ultimate consequence of this is a higher cost price, higher requirements for the size of the space and the load-bearing capacity of the anchoring for such a system.
    If the roilo is wider, this is solved by splitting it up and placing intermediate supports.
    In addition, if more turns on the take-up shaft are required, it is generally necessary to use a smaller diameter take-up shaft, which in turn leads to greater deflection and greater problems as described above.
    US2014 / US2014 / 0157547 discloses an electrical system for operating the roll axis.
    One end of the elastic band is firmly anchored to the shaft, the other side of the band being wound on a spool in a rolled up state! which is mounted on an axis parallel to the take-up axis.
    When the blind is lowered, this pre-tensioned belt is wound on the axle and helps hold the blind in position when the blind stops.
    When rewinding, the belt is rewound on the spool by the tension and thus helps the electric motor.
    As a result, the electric motor can have a lower power.
    The document does not solve the rolasad deflection problem.
    US2013 / 0333848 discloses an electrical system for controlling the hollow shaft of a rolio.
    Within the shaft is a concentrically arranged carrier with a drive unit comprising an electric motor and a control unit, and adjacent to this drive unit a pair of prestressed torsion springs are mounted in the shaft of the carrier.
    These torsion springs are biased during the lowering of the rolio and the cumulated energy of the springs then assists the rollo in rewinding. The above document also does not solve the problem of shaft deflection.
    WO2013 / WO2013 / 129916 A1 discloses electrical operation of a roller blind by means of two concentrically placed drive units. In the preferred embodiment, an auxiliary spring unit is coiled concentrically on the carrier between the drive units. This unit includes a torsion spring, with one end of the spring wire attached to the bottom bar and the other end attached to the roller shaft. When the blind is lowered, this torsion spring is tensioned and when the blind is rolled back up, the accumulated energy of the spring helps to wind the blind. Also, this document does not solve the roll axis deflection problem.
    It is an object of the present invention to provide a retractor mechanism that eliminates the unwanted deflection of the reel shaft and thereby the problems associated therewith.
    Summary of the invention The above drawbacks are eliminated by the retractor based on the invention, characterized by a reinforcement shaft inserted into the reel shaft and anchored firmly to the frame on the side opposite the actuation, the bending direction of the reinforcement shaft (6) is opposed to the expected deflection of the winding shaft (2) and the initial curvature of this ornamental axis (6} is such that its deformation along its length is such that at maximum deformation its axis coincides with the axis of the originally nist-deformed winding shaft ( 2} and the reinforcement shaft (6) is provided with support bearings (10) spaced apart along the length of this reinforcement shaft. In a preferred embodiment, this reinforcement shaft is in the form of a hollow or solid profile and between the inner diameter of the reinforcement shaft. the support bearings and the outer surface of the reinforcement shaft have molded spacers provided with an opening over them meets! with the cross-sectional shape and size of the trim axis and the cylindrical spherical surface of the inserts bowl! conforms to the shape and size of the inner surface of the inner ring of the support bearings so as to allow rotation of the roll-up shaft relative to the reinforcement shaft.
    * BE2019 / 5743 Clarification of Drawings The invention will be presented with the aid of drawings, in which Figure 1 is a perspective view of a take-up mechanism taking up from an assembled take-up shaft; FIG. 2 is a schematic cross-sectional view of the blind, FIG. 3 is a schematic cross-sectional view of the prior art take-up shaft, FIG. 4 is a view of the reinforcement shaft of the rollomechanism according to the invention, FIG. 5 is a cross-sectional view of a reinforcement shaft disposed in the roll-up shaft of FIG. 1 and FIG. 6 is a perspective view of the reinforcement shaft system without the take-up shaft. Detailed Description of the Invention "Rolling Support Bearings" as described herein will overturn any bearings suitable to allow roller bearing movement of the roll up shaft relative to the fixed reinforcement shaft. These bearings can overturn rolling elements, such as ball bearings, but can also be jib bearings or rolling slide bearings without moving or rolling elements. The "vineite" or "yield point" as described herein is defined with an ultimate yield point of 0.2% plastic elongation. In a first aspect, the invention relates to a roll-up mechanism comprising a roll-up shaft (2) made as a tube, the roll-up mechanism comprising a reinforcement shaft (6) which is bent, the decoration shaft being provided with tie bearings (10) spaced apart from one another. placed together along the length of said reinforcement shaft, the reinforcement shaft (6) being inserted into the winding shaft (2) so that said winding shaft (2) can rotate independently of said strengthening shaft (2).
    To insert the curved reinforcement shaft, fitted with sleeve bearings, into the take-up shaft, the curved reinforcement shaft must be straightened. This straightening of the reinforcement shaft is preferably a fully elastic deformation. The elastic deformation of the reinforcement shaft will act as a counterweight on the take-up shaft. This force is ideally opposite to the expected deformation of the roll-up shaft under any load. Typically, this load will result from the weight the roller system carries, particularly its own weight, the weight of the cloth attached to it, as well as any weighting to hold this curtain.
    While the force is ideally opposite to the expected deformation, the strength of the reinforcement shaft fully compensates for the weight acting on the roll-up shaft, and even in a non-ideal scenario it in any case improves upon the current state of the art. . That is, the resulting force will be the vector sum of these forces. As long as the norm of the resulting vector is less than the norm of the weight acting on the take-up shaft, the deflection by the take-up shaft will be significantly reduced.
    The reinforcement shaft thus creates a counterweight on the roll-up shaft. This force can be easily defined to be opposite to the weight acting on the take-up shaft. As a result of these opposing forces, the force due to the weight of the fabric on the roll-up shaft is significantly reduced. This increases the dimensional stability and stiffness of the roll-up shaft. In particular, it prevents the take-up shaft from sagging under the weight of the fabric. This also allows the use of materials with a higher specific weight. It also allows the use of smaller diameter roll-up shafts. With this, retractors with a longer length can be made. Finally, it also allows the use of roll-up shafts with a lower Young's modulus.
    In a preferred embodiment, the straightening of the reinforcement shafts is elastic deformation, that is, below the visual point of the roll-up shaft. A force applied to the reinforcement shaft which results in a plastic deformation of the shaft does not lead to the desired counterforce. It is only the elastic deformation that produces the desired effect. Accordingly, it is preferred that there is no plastic deformation on the winding shaft or reinforcement shaft during insertion of the reinforcement shaft or during operation.
    As a result, it is desirable that the curved wear shaft can be straightened, that we say, inserted into a straight take-up shaft, without exceeding its vice point. In practical terms, the offset yield point of 0.2% plastic elongation should not be exceeded when placing the curved reinforcement shaft in the roll-up shaft.
    In a preferred embodiment, the retractor according to the first aspect is wherein the reinforcement shaft has a central region between ringed ends, the reinforcement shaft having an extremum in said central region.
    BE2019 / 5743 An extremum as described herein includes a point where the first derivative of a curve representing the shape of the curved reinforcement axis is zero relative to the axis of the roll-up axis.
    This extremum can be a minimum or a maximum.
    Having said extremum in said central region of the reinforcement axis promotes the central action of the counterforce.
    Preferably, the extremum of the reinforcement shaft when inserted into the roll-up shaft coincides with the central region of the roll-up shaft.
    This is beneficial when the weight acting on the roll-up shaft is more or less co-ordinated.
    This is usually the case for roll-up shafts to which a cloth is attached.
    In another preferred embodiment, the invention relates to a reaming mechanism comprising a recoil shaft which is inserted into the roll shaft and tightened firmly to the sleeve on the side opposite the drive, the direction of bending of the reinforcement shaft being opposite to the expected deflection of the roll shaft. and the initial curvature of this shroud is such that its deformation along its length is such that at maximum deformation its axis coincides with the axis of the originally undeformed take-up shaft, and the shroud is provided with spaced apart roller bearings. spaced apart along the length of the take-up shaft. in this embodiment, the unloading weight force and the weight acting on the roll-up shaft will completely counteract each other.
    This is advantageous for maintaining a straight take-up shaft, regardless of its length, diameter, Young's modulus or weight acting on.
    In a preferred embodiment, the reinforcement has a circular or vesicular shape in cross-section.
    Polygon shapes are suitable for keeping the reinforcement axis fixed with respect to the rotatable layered retractor.
    Round shapes are suitable for providing the trim shaft with bearings, regardless of the orientation of the roller bearings with respect to the reinforcement shaft.
    In a further preferred embodiment, the reinforcement has a circular or regular polygonal cross-sectional shape.
    A regular polygon shape is defined by equal angles and sides.
    A regular polygon shape is advantageous because it allows easier connection of the rolling support bearings on the trim shaft.
    In addition, it allows the use of standard shapes for reinforcement shafts of different lengths and deflections with modular roller bearings.
    In a preferred embodiment, the drive (8) is a motor, said motor (8) being coupled to said roll-up shaft (2} and said support (7). The motor is preferably an electric motor. The motor is mounted so that the roll-up shaft can rotate while the bracket and reinforcement shaft remain stationary when the motor is running. In a preferred embodiment, the take-up system further comprises a power supply unit electrically coupled to the motor and configured to supply power to the motor. In a further preferred embodiment, the motor is located inside. the take-up shaft (2}. This is considered more aesthetically pleasing because the consumer view is limited to the roll-up shaft and fabric, It provides a motorized take-up system that does not sag or sag and has no additional box or connector. In a preferred embodiment, the roll-up shaft made of aluminum, steel, preferably profiled steel, composite materials such as fiberglass or other tubular materials. Aluminum is a strong, durable yet lightweight material. Reducing the weight of the roll-up system is often desirable and allows easier and safer mounting of the roll-up slat on the wall or ceiling.
    In a preferred embodiment, the reinforcing shaft is made of a high Young's modulus material. This is advantageous because materials with a higher Young's modulus exhibit less pre-bending and rechibulging as a counterforce to the same weight when straight-bent and inserted into the take-up shaft. In a preferred embodiment, the Young's modulus is at least 180 GPa, preferably at least 190 GPa, more preferably at least 195 GPa, more preferably at least 200 GPa, most preferably at least 205 GPa. In a preferred embodiment, the reinforcement shaft is made of a material! with a high yield point. Preferably the yield point, measured at a yield point of 0.2% plastic elongation ROO.2, is at least 250 MPa, preferably at least 300 MPa, more preferably at least 350 MPa, more preferably at least 400 MPa, with more preferably at least 450 MPa, more preferably at least 500 MPa, more preferably at least 550 MPa, more preferably at least 600 MPa, more preferably at least 850 MPa, more preferably at least 700 MPa, most preferably preferably at least 750 MPa. A high fly limit favors a greater counterforce exerted by the reinforcement shaft. This makes a higher yield strength advantageous for reinforcement shafts of higher weight, longer length or smaller diameter.
    In another preferred embodiment, the reinforcement shaft is made of steel, preferably profiled steel, composite materials such as glass fiber or other tubular materials. Steel has a high Young's modulus and a high vice-limit. This is particularly advantageous for the reinforcement shaft. In a more preferred embodiment, alloys with high strength properties such as ASTM A514 steel are used. The preferred shape of the reinforcement shaft, before it is inserted into the take-up shaft, will now be described in more detail. If we predict the axis of the trim axis as a curve, this curve is preferably flat, that is, it fits within a plane. This is beneficial for compensating for unidirectional forces. Since weight, due to the nature of gravity, can be considered a unidirectional force for this purpose regardless of the orientation of the roller, it is beneficial for the axis of the gain axis to be a flat curve.
    In a preferred embodiment, at least a central portion of the shaft of the reinforcement shaft can be threaded into a chain line. More preferably, the shaft can be fitted in a symmetrical chain. In particular, this keithline can be represented by the curve y = a cosh (x / b}, where cosh is the hyperbolic cosine function, x and y are variables determining the curve, and a and b are parameters, if a = b then The top line is not loaded, This approach can be used if the take-up shaft weighs significantly more than the fabric, However, if the weight of the roll-up shaft and the reinforcement shaft is small compared to the total weight acting on the take-up shaft, a and b should be independent parameters are seen. This shape is preferred because any tension or pressure exerted on the roll-up shaft of the above shape is parallel to this shape, compensated by the weight it is intended to receive. These curves are known in the art for weight distribution and / or weight distribution. or voltage along an arc In another embodiment, when at least one central part of the axis of the gain axis is shown as a curve, this curve can be approximated by the shape of a parabola, represented by the curve y = a x2. In a preferred embodiment, the ideal catenary can be approximated by a Taylor expansion. More preferably, said Taylor expansion includes only components with an even exponent. This is preferred to obtain a symmetrical curve. The reinforcement axis is preferably symmetrical assuming that the winding axis is perpendicular to gravity. Approximating the shape of the gain axis as a parabola or Taylor series is easier to control and model, allowing for more simple production.
    The reinforcement shaft has a central part and two ends. The central part, as described above, is ideally located on a particular curve. However, the ends need not lie on this curve. These ends can be bent differently. These owl ends may be straight to allow easy attachment to a support to hold the reinforcement shaft in place.
    The roll-up shafts according to the invention will be determined in function of the linear weight they can bear. This linear weight is considered to approximate the weight of the fabric, possibly with additional loads. As such, it is measured or rated for uniform loads acting over the entire length of the roll-up shaft. The height of the blind and the specific weight of the fabric and the extra weight of a possible bottom weld on the fabric are taken into account. in a preferred embodiment, the roll-up shaft has an outer diameter less than 50 mm, preferably less than 47 mm, most preferably less than 45 mm, and a length of at least 4 m, preferably at least 4.5 m, most preferably preferably at least 5 m. This is suitable for carrying a linear weight of at least 1250 g / m.
    In a preferred embodiment, the roll-up shaft has an outer diameter of less than 40 mm, preferably less than 35 mm, more preferably less than 32 mm, with the knife less than 30 mm, and a length of at least 3.5 m, preferably at least 4 m, most preferably at least 4.5 m. This is suitable for carrying a linear weight of at least 500 g / m.
    In a preferred embodiment, the roll-up shaft has an outer diameter of less than 100 mm, preferably less than 80 mm, more preferably less than 78 mm, most preferably less than 75 mm, and a length of at least 5 m, preferably at least 5 m, most preferably at least 7 m. This is suitable for carrying a linear weight of at least 4000 g / m. These preferred embodiments make it possible to hang blinds with a high linear weight on long roll-up shafts with a small outer diameter. This allows the roller blind to be placed in a smaller space and look aesthetically pleasing. Despite this, the take-up shaft will not bend under the linear weight over time due to the reinforcement shaft. For the same pipe length and diameter, it is therefore possible to carry a higher linear weight, so that roller blinds can, for example, be longer or can carry a higher specific weight. Roilos with a higher specific weight allow the use of heavier materials that can be warmer, better insulated, less translucent or simply to provide more options.
    In a second aspect, the invention relates to a kit suitable for constructing a roll winding mechanism, comprising: - a take-up shaft (2) made as a tube, - a reinforcement shaft (6) that is bent, configured to the roll-up shaft (2) to be inserted, and - rolling support bearings (10) configured to be spaced apart along the length of the reinforcement shaft (6). In a preferred embodiment of the second aspect, the invention relates to a kit suitable for constructing a roll-wrapping mechanism, comprising: - a support {7}, - a roll-up shaft (2) made as a tube attached at one end to a drive (8) provided to be attached to the support (7) and placed at the other end on a bearing placed over a pin attached to the support (7), - a reinforcement shaft (6) which is adapted to be inserted into a take-up shaft (2) and anchored firmly to the support (7) on the side opposite the drive (8), the direction of bending of the reinforcement shaft (6) is opposite to the expected deflection of the take-up shaft (2) and the initial curvature of this reinforcement (6) is such that its deformation along its longitudinal axis at maximum deflection coincides with the axis of the originally undeformed take-up shaft (2) and rolling support bearings (10) adapted to be spaced apart Line along the length of the reinforcement shaft (6).
    N BE2019 / 5743 The kit of the second aspect can be advantageously used to make and assemble a roll wrapping mechanism according to the first aspect. Furthermore, this kit can be used with different types of roller blinds if desired. This allows the kit to be used as a modular system for different types of blinds, which can have different weights, specific weights or densities, heights, colors and structures. In a preferred embodiment, the kit further comprises a blind (4} adapted to be attached to said roll-up shaft (2}. In a more preferred embodiment, the kit comprises a blanket attached to said roll-up shaft. In another preferred embodiment, the reinforcement shaft (6) provided with said rolling support bearings (10) is spaced apart along its length and said drive (8) is inserted into said take-up shaft (2). the fabric and the roll-up shaft system and / or the construction of the reinforcement shaft and roll-up shaft set makes the construction and assembly of the roll-up system easier, and it also prevents mistakes in the construction by the consumer or skilled person in roller blinds that assemble the said roll-up shaft. is the perspective view of the roller blind roll-up shaft 2, which is part of the roll-up mechanism 1. This is shown in detail in F ig. 5 and 6. A protruding part of the drive 8 can be seen. On the surface of the roll-up shaft 2, an anchoring greeting 11 in the inward direction can be provided for attaching one end of the roll cloth.
    FIG. 2 is a schematic side view of an embodiment of a roller blind. The basis is the roll-up shaft 2 on which a fabric element 4, which can be a lamella blade, armor, woof or a foil, is rolled, which is provided with weighting 5 at its free end to tension the fabric. The rolled-up element 4 is hidden in the cassette 3. A dotted line indicates the cross-section of a gain 6, which will be discussed later, FIG. 3 shows the roll-up shaft 2 according to the state of the art, under the load of its own weight, the weight of the fabric element 4 and the weight of the weighting 5. The arrow A indicates the direction of bending of the roll-up shaft 2. The take-up shaft 2 is provided at one end with the drive 8 which is attached to a support 7 or to the wall and at the other end is attached over a pin 13 which is attached to a slider 7. The ball bearing S is mounted on the pin 13 with its inner ring, while the winding shaft 2 fits over the outer ring with its inner diameter. The drive 8 can be manual or as an electric motor.
    FIG. 4 shows a pre-bent or pre-tensioned reinforcement shaft 6 which is part of the take-up reel mechanism 1 according to the invention. This reinforcement shaft 6 increases the stiffness of the shaft 2 in the bending plane. The reinforcement shaft 6 is inserted into the roller shaft 2 and anchored firmly to the support 7 on the opposite side of the drive 8, so that it does not rotate and still opposes the force that would cause the shaft 2 to deflect even when rotated is. The direction of deflection of the reinforcement shaft 6 is indicated by the arrow! It is opposite to the expected deflection of the winding shaft 2. The initial curvature or bias of this reinforcement shaft 5 is chosen such that the deformation along its length is such that its axis at maximum deformation will coincide with the axis of originally unbent winding shafts 2 and therefore the take-up shaft 2 remains upright during use. Fine tuning or compensation of the residual deformation after placement of the reinforcement shaft 6 is done by adjusting the weight or distributing the load 5. FIG. 5 is a schematic cross-sectional view of the mechanism 1 mounted in the roll-up shaft 2 of the roller of Figure 1. The reinforcement shaft 6 is anchored on the opposite side of the drive 8. The reinforcement shaft 6 replaces the function of the pin 13. The roll-up shaft 2 is supported by the bearings 10 which are spaced apart along the length of the reinforcement shaft, so that the take-up shaft 2 can rotate about the stationary reinforcement shaft 6.
    FIG. 6 shows a perspective view of the uncovered rowing mechanism 1 and the mounting of the support bearing 10 at the edge of the reinforcement shaft and the placement of further support bearings 10 along the length of the reinforcement G is clearly visible. The support bearings 10 are designed as ball bearings and are spaced apart along the length of the reinforcement shaft. The reinforcement shaft 6 preferably has a round, square, rectangular or polygonal cross-section and loops the inner diameters of the support bearings 10 and on the outer surface of the reinforcement 6 adapters 12 are provided with an opening corresponding to the shape and size of the outer surface of the reinforcement. reinforcement shaft 8 of the winding shaft 2, and a cylindrical outer surface corresponding to the shape and size of the inner surface of the inner ring of the bearings 10 to allow rotation of the winding shaft 2 with respect to the reinforcement shaft 6.
    Industrial applicability The retractor can be applied wherever it is necessary to increase the resistance of the retractor shaft to deflection due to unidirectional loading, especially for various roller blinds systems such as fabric blinds, screens, roller shutters, roller shades, roller gates and all kinds of roll-up systems especially of great breedie.
    It can be used wherever there is excessive unwanted deflection of the take-up shaft, where a larger amount of fabric is to be wrapped and it is necessary to use a smaller diameter shaft, where long shafts have to be used or where a larger shaft diameter is not required. can be used due to lack of space for installation or due to the dimensions of the cassette and therefore the take-up shaft must be reinforced.
