4-in-1 automatic shutter cleaner with heat insulation, acoustic insulation, barrier against insects

Abstract

Automatic blind cleaner with thermal insulation, acoustic insulation, and insect barrier. It cleans blinds using a system that balances the blind-cleaning equipment by using a blind-cleaning support, which has a pin that supports and on which a trigger pivots and balances. This pin traps a housing, inside which there is a main strip and individual strips, which regulate the pressure of the brushes against the blind in a fully automatic manner, with new brushes that have appendages at their ends for deeper and more effective cleaning. The blind cleaning unit along with the insulating foam prevents air, noise, and insects from entering the blind box between the projection and the casing

Description

TECHNICAL FIELD

[0001] The invention lies within the technical field of domestic washing or cleaning, more specifically relating to the cleaning of blinds and awnings, as well as in the field of enclosures, windows, and blinds, with respect to the thermal and acoustic insulation of housing.BACKGROUND OF THE INVENTION

[0002] Currently, there is no known system capable of cleaning blinds externally while simultaneously incorporating three additional functions within the same mechanism: thermal insulation, acoustic insulation, and an insect barrier. This provides considerable savings in materials, time, cleaning products, energy, and a significant improvement in quality of life. Various inventions have been patented to address the problem of cleaning the exterior of blinds, such as patent P200602903, which uses a support with one roller and two brushes, or patent ES2153731, which discloses a cleaning system for the external part of the blind using a movable roller engaged with a drum, and patent ESI038501, which describes a system for cleaning blinds using a rotating brush. These patents, however, focus solely on one function the cleaning of blinds. After analysing the different external blind cleaners, it has been observed that a large number of pulleys and gears are required for roller rotation, as well as the difficulty and danger involved in assembling, installing, and maintaining these mechanisms, which are also bulky. Similarly, no system has been found that combines thermal or acoustic insulation or insect protection with the ability to clean the blinds. Moreover, existing insulation systems have focused on insulating the blind box, where various materials such as polyurethane foam, glass wool, or foam are used. Inside the blind box, this is generally only possible during manufacturing in carpentry workshops. For blinds already installed, it is often very difficult or even impossible due to a lack of physical space for the insulator, as well as the difficulty and time required for installation.EXPLANATION OF THE INVENTION

[0003] The present invention refers to a device located on the upper part of the outer face of the blind and parallel to it along its entire width, whose main function is the external cleaning of the blind, as well as providing thermal insulation, acoustic insulation, and an insect barrier. The automatic 4-in-1 blind cleaner is capable of cleaning the external face of the blind in less than 3 seconds, twice a day, more than 700 times a year, and keeping the internal part clean as well as shop shutters, garage doors, and awnings that have the same mechanical principle, without doing anything beyond the usual operation of raising and lowering the blinds. During this same raising and lowering process, a set of self-supporting brushes operates with six simultaneous actions: sweeping solid residues, drying, polishing, providing thermal insulation, acoustic insulation, and an insect barrier. These brushes are located inside a housing and are supported by a trigger-operated blind cleaning support assembly. The great innovation of this automatic blind cleaner, without detracting from the improvements of the first blind cleaner P200602903, lies in providing this automatic blind cleaner with three additional functions: thermal insulation, acoustic insulation, and insect barrier. With minimal cost, it takes advantage of all the components of the blind cleaner and only adds a strip of insulating material that adheres to the top of the blind cleaner housing, either by adhesive or by insertion into a track of the housing. Tests showed that this blocked air, noise, and insects that could enter through the front of the blind, allowing only air, noise, and insects to enter from the rear part of the blind. Therefore, sponge, rubber, or hair brushes were added longitudinally to the upper inner part of the blind, attached to the base of the blind box, in full contact with the blind to block air, reducing by more than 90% the air currents, noise, and insects entering the blind box. By adding these two components, we achieve three functions: thermal insulation, acoustic insulation, and an insect barrier, resulting in improved quality of life for the tenant by eliminating acoustic contamination leaking through the blind box. Furthermore, we obtain a noticeable improvement by reducing the transfer of heat from the dwelling through air currents leaking through the blind box. This blind cleaner consists of two systems: Easy Fix, for easy installation and maintenance, and Full Kontakt, for deeper and more effective cleaning of the blind, thanks to its new special brushes and its independent brush positioning system through individual self-supporting brushes. The Easy Fix system uses a support with a trigger. This support features holes at its base and on the side support of the blind cleaner, allowing it to be fixed with screws to the guide of the blind cleaner or to the side wall. For this, we apply double-sided adhesive tape to the lateral support of the blind cleaner on the desired face and then attach it to the guide of the blind at the top or to the wall at a 90° angle, either temporarily or permanently depending on the adhesion strength of the double-sided tape. Afterwards, for better and safer fastening, a screw can be added if attached to the profile of the blind guide, or a plug and screw if on the side wall. When pressing the support with the double-sided tape and screw, the blind cleaner support becomes fixed and no longer requires additional screws, avoiding the need to drill very close holes that could damage the wall. The use of double-sided adhesive tape allows safer work since we do not need to perform complicated manoeuvres to hold the blind cleaner support with one hand while drilling and screwing with the other, often leaning halfway out of the window. From the base of the support, on its upper side, protrude two walls, one on each side, crossed by a shaft where a latch is installed. This latch holds and secures the automatic blind cleaner within longitudinal slots on the housing of the blind cleaner unit. These slots may have a regular or irregular shape. This latch includes a safety button on the trigger support or another regular or irregular form that fits the negative shape of the longitudinal slot of the housing. This allows the blind cleaner unit to be firmly locked without slipping or loosening when pressed against the trigger foot's projection, ensuring a secure grip of the blind cleaner unit. In addition, this latch has another key function: it helps regulate the brush pressure. Thanks to its oscillation, when the blind moves downward, if the blind cleaner were always parallel to the blind surface, the blind could not descend by its own weight due to friction from the brushes. It would require additional stops or heavy counterweights to overcome the friction generated. Since the blind cleaner is supported by the trigger and traversed by a shaft fixed to the support, it allows a slight balance of the blind cleaner unit in relation to the blind, which, along with other mechanisms such as compression and expansion springs (both in the main and individual parts, as well as in the brush extensions), provides smooth operation and balance during cleaning. These mechanisms work during the change of direction of the blind slats, causing the rubber brush body to twist and change direction at the height of the equidistant holes in the rubber body, thus greatly facilitating and reducing the friction of the brushes against the blind when it reaches the top point and begins the downward process. Without these mechanisms, a very heavy counterweight would be required. Once the blind begins to descend, the main spring and the individual springs push the brushes against the blind, adapting to its shape. As the blind tries to separate from the brushes, the retaining fins of the housing collide with the lower safety peak of the blind cleaner support, preventing further retreat and forcing the springs to perform their compression and expansion function of the brushes against the blind. Conversely, when the blind rises and changes direction, the brushes are drawn towards the blind due to the friction exerted, ensuring full contact with it, which increases both the cleaning and insulation power. The friction generated is counter balanced by the force exerted to raise the blind through the electric motor belt. If the pressure exerted by the brushes is too high, the blind will not rise, and if too low, it will not clean properly. This latch secures the blind cleaner structure at two or more points, similar to the operation of crab pincers. This system allows the cleaner to be assembled or disassembled with two fingers and no tools in under three seconds. Moreover, this blind support includes an upper safety tip for the blind cleaner in the middle section, allowing it to hang from the support when the trigger is released. Depending on the shape and dimensions, slight upward pressure may be required to find the ideal position to remove it safely. Additionally, a safety cord has been added, anchored to a hole at the bottom of the support, which connects to the blind cleaner housing to prevent accidental falls. The Full Kontakt system provides a larger contact area and greater independence of the brushes for deeper cleaning than patent P200602903, which I know best as its creator, having led its evolution and development to this most advanced version to date. That patent used a rigid housing containing the roller and brushes, designed to supply cleaning liquid and prevent its evaporation for days. However, to achieve better cleaning results, this rigid, heavy, and bulky housing has been replaced with a new, more advanced self-supporting brush with six simultaneous actions: cleaning, drying, polishing, thermal insulation, acoustic insulation, and an insect barrier. This new design offers greater cleaning power, is lighter, more flexible, and independent. It also includes a double brush holder for blinds with PVC or wooden frames, which can be cut at its midsection to be used on aluminium blind frames with thinner profiles, becoming a thinner brush support adaptable to multiple frame types. This brush support includes both lower and upper retaining stops that hold the brush support assembly, springs, and brushes within the housing of the blind cleaner. This allows free movement while preventing the brushes from coming out of the housing. The brush support has holes both for installing the brushes and for inserting the springs. The main spring provides the greatest compression and expansion travel of the self-supporting brush assembly, while individual springs maximise the cleaning and insulation power of each brush by allowing them to move independently with slight motion inside their cavities. By pushing each self-supporting brush with its own individual spring, greater flexibility and independence of movement are achieved. A co-extrusion process has been used for the brush of the blind cleaner unit, which now includes a rigid section made of plastic, aluminium, or other metalic material joined to a flexible rubber part. At the end of this flexible section, one or more rubber appendages are attached, which sweep, dry, and adapt to the shape of the blind slats, reaching areas previously inaccessible. In the rubber body near the appendages, equidistant holes have been arranged to help flex the brush body in this area, allowing a smoother and more gradual change in direction of the brushes. Over these holes, sponge or similar strips are affixed on both sides of the rubber body and close to the appendages for sweeping and drying. Another type of brush may also be used, where at the opposite end of the appendages there is a regular or irregularly shaped cylindrical body inserted into a rigid housing made of plastic, metal, aluminium, or other material, open to allow insertion of the rubber body. In addition to self-supporting brushes, there are also brushes made of synthetic bristles. The normal configuration consists of one bristle brush in the lower part of the 4-in-1 blind cleaner unit and one or two self-supporting brushes above it, although the composition, layout, and number of brushes may vary. This new configuration makes each brush independent and far more flexible ensuring that the brushes maintain contact across the full width of the blind even if it deforms in the centre or at any point. These brushes adapt perfectly to all situations and to the shape of the blind. The appendage or plurality of appendages at the end of the brush provides deeper cleaning, reaching areas otherwise inaccessible. Furthermore, these appendages reduce the effort required when changing the direction of the blind slats, as their flexibility at the joining edges of the slats allows smooth bending of the brush body and continuous contact with the slats. As these appendages remain in constant contact with the blind on one side orthe other they practically eliminate air, noise, and insect infiltration. This system achieves a smaller, lighter, and more streamlined blind cleaner, with greater cleaning power of the blind slats through the use of lighter and more flexible self-supporting brushes with higher cleaning efficiency. It is also more economical and environmentally friendly, as in 99% of cases it requires no cleaning products or external systems of any kind. These brushes do not require any auxiliary energy for operation, since raising and lowering the blind something we do daily activates the system. These brushes can be sprayed or soaked to supply cleaning products, antistatic agents, or anti-pollution solutions for cleaning blinds in urban environments. Additionally, they serve as thermal and acoustic insulation and as a barrier against insects, preventing the entry of air currents, noise, and insects into the interior of the blind system. To prevent air from entering through the inner part of the blind into the blind box, a brush is installed and secured to the base of the blind box. If total insulation of the blind box is desired, it can be covered with post-formed moulds of insulating material, such as fibreglass wool, rock wool, foam, or similar materials.BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The easiest and most economical way to implement the present invention is to position at least one double self-supporting brush (13) parallel to the blind, improving its effectiveness with a greater number of brushes. These are held by a housing (1) made of aluminium, PVC, or similar material, fixed to the upper external window frame or wall using supports (5). These supports allow the cleaning device (0) to be released via a trigger (4) and include an insulating strip at the top of the housing (1). In a first preferred embodiment, the 4-in-1 blind-cleaning device (0) comprises: a housing (1), a trigger-type blind-cleaner support (0-1), a brush, spring, and brush-holder assembly (0-2), an insulating foam strip (2), a safety cord (3), and weighted blind stops (19), without limitation regarding the number of pieces, shapes, or arrangements. The housing (1) has a rectangular shape open on one side, from which extend retaining fins (1-2) that allow the brush and spring support assembly (0-2) to move freely within the housing (1) and automatically adjust the necessary pressure so that brushes (13), (14), and (15) can clean the blind while preventing air currents from entering the blind box (16-1), thus affecting the thermal and acoustic insulation of the dwelling (see Figs. 17, 18, 19, 20, 21, 28). Additionally, the retaining fins (1-2) limit the movement of the 4-in-1 blind-cleaning device (0) when performing its cleaning function, as brushes (13) and (15) push backward the entire brush and spring support assembly (0-2) against the housing (1). This movement is restricted by the lower safety tip (5-5) of the blind-cleaner support (see Figs. 17, 18, 19, 20, and 21), initiating the compression of springs (11) and (12) that apply pressure to brushes (13) and (15) against the blind (16), thus providing the necessary and automatic pressure for effective blind cleaning and prevention of air currents. The housing (1) also features slots (1-1) whose function is to secure the complete 4-in-1 blind-cleaning assembly (0) to the trigger (4) through the trigger safety button (4-2), which fits into the slot (see Fig. 32, 33). This ensures secure attachment, forming a single block that pivots on the pin (7) (see Figs. 17, 18, 19, 20, 21), providing greater or lesser pressure in conjunction with the support assembly, brushes, and springs (0-2). The housing (1) also includes a channel (1-4) running along its entire length (see Figs. 8 and 9) for inserting a co-extrusion of rigid plastic, aluminium, or metallic material, along with a brush made of synthetic bristles or rubber with a regular or irregular shape (2-1). It can also be replaced by a co-extrusion of rigid material and hollow insulating rubber (2-4) from which one or more appendages may protrude to prevent the entry of air, noise, or insects through the upper part of the 4-in-1 blind-cleaning device (0). This insulating rubber may also be replaced by a co-extrusion with bristles, depending on the specific requirements of insulation and cleaning. A linear sponge (2) adhered with adhesive along the upper part of the housing (1) serves as an insulating element. This housing (1) also includes other slots (1-3) on its sides to allow the attachment of an extension adaptor (18) for the blind-cleaner housing (1) (see Figs. 39, 40, 41). This adaptor is similar in shape to the housing but of a smaller size, designed to be installed inside the housing (1) when it is shorter, or when a blind-cleaning unit of greater height than standard is required, or for packaging reasons. The extension adaptor is secured to the housing with screws. For the installation of the support (5) of the 4-in-1 blind-cleaning unit (0) on the blind guide or wall, double-sided adhesive tape (8) is applied to the base or side of the support (5). Once the adhesive is fixed, the support (5) is attached to the blind rail or wall and further secured with a screw (9) or plug and screw (6), as appropriate, ensuring greater safety and stability. This support (5) incorporates a trigger (4) attached via a pin (7) that allows oscillation of the cleaning unit (0) (see Figs. 35, 17, 18, 19, 20, 21). The retaining fins (1-2) stop the movement of the blind-cleaning support at the lower safety tip (5-5), limiting its motion (see Figs. 17-21). When the blind descends, the main spring (11) begins to operate, compressing and expanding, while the individual springs (12) move the self-supporting brushes (13) and the bristle brush (15) closer or farther apart depending on. The pressure exerted by each brush against the blind (16). The brushes (13) and (15) flex or straighten according to the force exerted individually, and the brush tips (13) and (14) include appendages (13-5) (see Fig. 26) or a plurality of appendages (13-6) (see Figs. 27, 17, 18, 19, 20, 21, 28, 29). These perform a secondary sweeping or drying action, sealing the blind more effectively against air, noise, and insect infiltration, thereby improving the airtightness of the system. Moreover, the appendage (13-5) or appendages (13-6) facilitate the change of direction of the brushes during the upward or downward transition of the blind by flexing smoothly upon contact with the edges of each slat (16) (see Fig. 29), resulting in smoother motion and requiring less counterweight for operation. To secure the brushes within the blind-cleaning unit (0), a double brush support (10) is used for PVC or wooden window frames, which typically have wider profiles than aluminium ones. For aluminium blinds, the double brush support (10) is shortened by half, becoming a single brush support (10-1) (see Figs. 10, 11, 12, 13). This support features elongated inner cavities (10-2) where brushes (13) and (15) are housed, allowing small movements depending on the pressure applied by the main brush spring (11) and the individual brush springs (12) against the blind (16). The main spring is positioned in the rectangular recess (10-4) of the brush support (10), ensuring controlled flexibility and automatic adjustment during operation. The individual springs are housed separately in the individual brush cavities (10-3) (see Figs. 14, 15, 16). This brush support (10) also features lateral extensions (10-5) that hold the brushes within the aluminium housing (1). When they come into contact with the retaining fins (1-2), they secure and permit free movement of the brush and spring assembly (0-2) within the housing of the blind-cleaning device (1) (see Figs. 17, 18, 19, 20, 21). These new brushes (13) are co-extrusions composed of a rigid material (13-1) such as plastic, aluminium, or another metal-joined to a flexible rubber (13-2) with a terminal appendage (13-5) or a plurality of appendages (13-6). This rubber includes equidistant holes (13-7) to improve adhesion of the sponges (13-3, 13-4) to the rubber (13-2), preventing displacement (see Figs. 22,23,24,25, 26, 27). These features also assist in the flexing of the brushes during directional changes, and by eliminating the traditional rigid body that held the brush, the design achieves greater lightness, flexibility, torsion, and independence. Figure 23 shows a brush (14) without co-extrusion, inserted into a rubber brush housing (14-1), which can be removed for cleaning or replacement. These brushes (14) have been enhanced with greater cleaning and insulation capacity by incorporating, at their ends, an appendage (13-5) or a plurality of appendages (13-6) (see Figs. 22, 26, 27, 29, 17, 18, 19, 20, 21). These appendages provide contact in areas previously unreachable, preventing the blind from raising while wet due to rain and stopping air currents, noise, and insects from entering the blind box. Because these appendages remain constantly in contact with the blind, together with the sponges and bristle brushes, the system now provides five protective barriers where previously there were only three. In a second preferred embodiment, in addition to all the components from the first embodiment, the brush (17) (see Fig. 28) is added to further prevent the entry of air currents, noise, and insects. In a third preferred embodiment, in addition to all the components of the first and second embodiments, an insulated blind box (16-1) (see Fig. 28) is used, resulting in a fully integrated insulation system for the entire blind. The present invention can be executed in various ways, allowing for modifications, additions, or removal of components, as well as variations in arrangement, shape, size, and the nature of materials, without altering the essence of the invention as.

TECHNICAL FIELD

[0001] The invention lies within the technical field of domestic washing or cleaning, more specifically relating to the cleaning of blinds and awnings, as well as in the field of enclosures, windows, and blinds, with respect to the thermal and acoustic insulation of housing.BACKGROUND OF THE INVENTION

[0002] Currently, there is no known system capable of cleaning blinds externally while simultaneously incorporating three additional functions within the same mechanism: thermal insulation, acoustic insulation, and an insect barrier. This provides considerable savings in materials, time, cleaning products, energy, and a significant improvement in quality of life. Various inventions have been patented to address the problem of cleaning the exterior of blinds, such as patent P200602903, which uses a support with one roller and two brushes, or patent ES2153731, which discloses a cleaning system for the external part of the blind using a movable roller engaged with a drum, and patent ESI038501, which describes a system for cleaning blinds using a rotating brush. These patents, however, focus solely on one function the cleaning of blinds. After analysing the different external blind cleaners, it has been observed that a large number of pulleys and gears are required for roller rotation, as well as the difficulty and danger involved in assembling, installing, and maintaining these mechanisms, which are also bulky. Similarly, no system has been found that combines thermal or acoustic insulation or insect protection with the ability to clean the blinds. Moreover, existing insulation systems have focused on insulating the blind box, where various materials such as polyurethane foam, glass wool, or foam are used. Inside the blind box, this is generally only possible during manufacturing in carpentry workshops. For blinds already installed, it is often very difficult or even impossible due to a lack of physical space for the insulator, as well as the difficulty and time required for installation.EXPLANATION OF THE INVENTION

[0003] The present invention refers to a device located on the upper part of the outer face of the blind and parallel to it along its entire width, whose main function is the external cleaning of the blind, as well as providing thermal insulation, acoustic insulation, and an insect barrier. The automatic 4-in-1 blind cleaner is capable of cleaning the external face of the blind in less than 3 seconds, twice a day, more than 700 times a year, and keeping the internal part clean as well as shop shutters, garage doors, and awnings that have the same mechanical principle, without doing anything beyond the usual operation of raising and lowering the blinds. During this same raising and lowering process, a set of self-supporting brushes operates with six simultaneous actions: sweeping solid residues, drying, polishing, providing thermal insulation, acoustic insulation, and an insect barrier. These brushes are located inside a housing and are supported by a trigger-operated blind cleaning support assembly. The great innovation of this automatic blind cleaner, without detracting from the improvements of the first blind cleaner P200602903, lies in providing this automatic blind cleaner with three additional functions: thermal insulation, acoustic insulation, and insect barrier. With minimal cost, it takes advantage of all the components of the blind cleaner and only adds a strip of insulating material that adheres to the top of the blind cleaner housing, either by adhesive or by insertion into a track of the housing. Tests showed that this blocked air, noise, and insects that could enter through the front of the blind, allowing only air, noise, and insects to enter from the rear part of the blind. Therefore, sponge, rubber, or hair brushes were added longitudinally to the upper inner part of the blind, attached to the base of the blind box, in full contact with the blind to block air, reducing by more than 90% the air currents, noise, and insects entering the blind box. By adding these two components, we achieve three functions: thermal insulation, acoustic insulation, and an insect barrier, resulting in improved quality of life for the tenant by eliminating acoustic contamination leaking through the blind box. Furthermore, we obtain a noticeable improvement by reducing the transfer of heat from the dwelling through air currents leaking through the blind box. This blind cleaner consists of two systems: Easy Fix, for easy installation and maintenance, and Full Kontakt, for deeper and more effective cleaning of the blind, thanks to its new special brushes and its independent brush positioning system through individual self-supporting brushes. The Easy Fix system uses a support with a trigger. This support features holes at its base and on the side support of the blind cleaner, allowing it to be fixed with screws to the guide of the blind cleaner or to the side wall. For this, we apply double-sided adhesive tape to the lateral support of the blind cleaner on the desired face and then attach it to the guide of the blind at the top or to the wall at a 90° angle, either temporarily or permanently depending on the adhesion strength of the double-sided tape. Afterwards, for better and safer fastening, a screw can be added if attached to the profile of the blind guide, or a plug and screw if on the side wall. When pressing the support with the double-sided tape and screw, the blind cleaner support becomes fixed and no longer requires additional screws, avoiding the need to drill very close holes that could damage the wall. The use of double-sided adhesive tape allows safer work since we do not need to perform complicated manoeuvres to hold the blind cleaner support with one hand while drilling and screwing with the other, often leaning halfway out of the window. From the base of the support, on its upper side, protrude two walls, one on each side, crossed by a shaft where a latch is installed. This latch holds and secures the automatic blind cleaner within longitudinal slots on the housing of the blind cleaner unit. These slots may have a regular or irregular shape. This latch includes a safety button on the trigger support or another regular or irregular form that fits the negative shape of the longitudinal slot of the housing. This allows the blind cleaner unit to be firmly locked without slipping or loosening when pressed against the trigger foot's projection, ensuring a secure grip of the blind cleaner unit. In addition, this latch has another key function: it helps regulate the brush pressure. Thanks to its oscillation, when the blind moves downward, if the blind cleaner were always parallel to the blind surface, the blind could not descend by its own weight due to friction from the brushes. It would require additional stops or heavy counterweights to overcome the friction generated. Since the blind cleaner is supported by the trigger and traversed by a shaft fixed to the support, it allows a slight balance of the blind cleaner unit in relation to the blind, which, along with other mechanisms such as compression and expansion springs (both in the main and individual parts, as well as in the brush extensions), provides smooth operation and balance during cleaning. These mechanisms work during the change of direction of the blind slats, causing the rubber brush body to twist and change direction at the height of the equidistant holes in the rubber body, thus greatly facilitating and reducing the friction of the brushes against the blind when it reaches the top point and begins the downward process. Without these mechanisms, a very heavy counterweight would be required. Once the blind begins to descend, the main spring and the individual springs push the brushes against the blind, adapting to its shape. As the blind tries to separate from the brushes, the retaining fins of the housing collide with the lower safety peak of the blind cleaner support, preventing further retreat and forcing the springs to perform their compression and expansion function of the brushes against the blind. Conversely, when the blind rises and changes direction, the brushes are drawn towards the blind due to the friction exerted, ensuring full contact with it, which increases both the cleaning and insulation power. The friction generated is counter balanced by the force exerted to raise the blind through the electric motor belt. If the pressure exerted by the brushes is too high, the blind will not rise, and if too low, it will not clean properly. This latch secures the blind cleaner structure at two or more points, similar to the operation of crab pincers. This system allows the cleaner to be assembled or disassembled with two fingers and no tools in under three seconds. Moreover, this blind support includes an upper safety tip for the blind cleaner in the middle section, allowing it to hang from the support when the trigger is released. Depending on the shape and dimensions, slight upward pressure may be required to find the ideal position to remove it safely. Additionally, a safety cord has been added, anchored to a hole at the bottom of the support, which connects to the blind cleaner housing to prevent accidental falls. The Full Kontakt system provides a larger contact area and greater independence of the brushes for deeper cleaning than patent P200602903, which I know best as its creator, having led its evolution and development to this most advanced version to date. That patent used a rigid housing containing the roller and brushes, designed to supply cleaning liquid and prevent its evaporation for days. However, to achieve better cleaning results, this rigid, heavy, and bulky housing has been replaced with a new, more advanced self-supporting brush with six simultaneous actions: cleaning, drying, polishing, thermal insulation, acoustic insulation, and an insect barrier. This new design offers greater cleaning power, is lighter, more flexible, and independent. It also includes a double brush holder for blinds with PVC or wooden frames, which can be cut at its midsection to be used on aluminium blind frames with thinner profiles, becoming a thinner brush support adaptable to multiple frame types. This brush support includes both lower and upper retaining stops that hold the brush support assembly, springs, and brushes within the housing of the blind cleaner. This allows free movement while preventing the brushes from coming out of the housing. The brush support has holes both for installing the brushes and for inserting the springs. The main spring provides the greatest compression and expansion travel of the self-supporting brush assembly, while individual springs maximise the cleaning and insulation power of each brush by allowing them to move independently with slight motion inside their cavities. By pushing each self-supporting brush with its own individual spring, greater flexibility and independence of movement are achieved. A co-extrusion process has been used for the brush of the blind cleaner unit, which now includes a rigid section made of plastic, aluminium, or other metalic material joined to a flexible rubber part. At the end of this flexible section, one or more rubber appendages are attached, which sweep, dry, and adapt to the shape of the blind slats, reaching areas previously inaccessible. In the rubber body near the appendages, equidistant holes have been arranged to help flex the brush body in this area, allowing a smoother and more gradual change in direction of the brushes. Over these holes, sponge or similar strips are affixed on both sides of the rubber body and close to the appendages for sweeping and drying. Another type of brush may also be used, where at the opposite end of the appendages there is a regular or irregularly shaped cylindrical body inserted into a rigid housing made of plastic, metal, aluminium, or other material, open to allow insertion of the rubber body. In addition to self-supporting brushes, there are also brushes made of synthetic bristles. The normal configuration consists of one bristle brush in the lower part of the 4-in-1 blind cleaner unit and one or two self-supporting brushes above it, although the composition, layout, and number of brushes may vary. This new configuration makes each brush independent and far more flexible ensuring that the brushes maintain contact across the full width of the blind even if it deforms in the centre or at any point. These brushes adapt perfectly to all situations and to the shape of the blind. The appendage or plurality of appendages at the end of the brush provides deeper cleaning, reaching areas otherwise inaccessible. Furthermore, these appendages reduce the effort required when changing the direction of the blind slats, as their flexibility at the joining edges of the slats allows smooth bending of the brush body and continuous contact with the slats. As these appendages remain in constant contact with the blind on one side orthe other they practically eliminate air, noise, and insect infiltration. This system achieves a smaller, lighter, and more streamlined blind cleaner, with greater cleaning power of the blind slats through the use of lighter and more flexible self-supporting brushes with higher cleaning efficiency. It is also more economical and environmentally friendly, as in 99% of cases it requires no cleaning products or external systems of any kind. These brushes do not require any auxiliary energy for operation, since raising and lowering the blind something we do daily activates the system. These brushes can be sprayed or soaked to supply cleaning products, antistatic agents, or anti-pollution solutions for cleaning blinds in urban environments. Additionally, they serve as thermal and acoustic insulation and as a barrier against insects, preventing the entry of air currents, noise, and insects into the interior of the blind system. To prevent air from entering through the inner part of the blind into the blind box, a brush is installed and secured to the base of the blind box. If total insulation of the blind box is desired, it can be covered with post-formed moulds of insulating material, such as fibreglass wool, rock wool, foam, or similar materials.BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The easiest and most economical way to implement the present invention is to position at least one double self-supporting brush (13) parallel to the blind, improving its effectiveness with a greater number of brushes. These are held by a housing (1) made of aluminium, PVC, or similar material, fixed to the upper external window frame or wall using supports (5). These supports allow the cleaning device (0) to be released via a trigger (4) and include an insulating strip at the top of the housing (1). In a first preferred embodiment, the 4-in-1 blind-cleaning device (0) comprises: a housing (1), a trigger-type blind-cleaner support (0-1), a brush, spring, and brush-holder assembly (0-2), an insulating foam strip (2), a safety cord (3), and weighted blind stops (19), without limitation regarding the number of pieces, shapes, or arrangements. The housing (1) has a rectangular shape open on one side, from which extend retaining fins (1-2) that allow the brush and spring support assembly (0-2) to move freely within the housing (1) and automatically adjust the necessary pressure so that brushes (13), (14), and (15) can clean the blind while preventing air currents from entering the blind box (16-1), thus affecting the thermal and acoustic insulation of the dwelling (see Figs. 17, 18, 19, 20, 21, 28). Additionally, the retaining fins (1-2) limit the movement of the 4-in-1 blind-cleaning device (0) when performing its cleaning function, as brushes (13) and (15) push backward the entire brush and spring support assembly (0-2) against the housing (1). This movement is restricted by the lower safety tip (5-5) of the blind-cleaner support (see Figs. 17, 18, 19, 20, and 21), initiating the compression of springs (11) and (12) that apply pressure to brushes (13) and (15) against the blind (16), thus providing the necessary and automatic pressure for effective blind cleaning and prevention of air currents. The housing (1) also features slots (1-1) whose function is to secure the complete 4-in-1 blind-cleaning assembly (0) to the trigger (4) through the trigger safety button (4-2), which fits into the slot (see Fig. 32, 33). This ensures secure attachment, forming a single block that pivots on the pin (7) (see Figs. 17, 18, 19, 20, 21), providing greater or lesser pressure in conjunction with the support assembly, brushes, and springs (0-2). The housing (1) also includes a channel (1-4) running along its entire length (see Figs. 8 and 9) for inserting a co-extrusion of rigid plastic, aluminium, or metallic material, along with a brush made of synthetic bristles or rubber with a regular or irregular shape (2-1). It can also be replaced by a co-extrusion of rigid material and hollow insulating rubber (2-4) from which one or more appendages may protrude to prevent the entry of air, noise, or insects through the upper part of the 4-in-1 blind-cleaning device (0). This insulating rubber may also be replaced by a co-extrusion with bristles, depending on the specific requirements of insulation and cleaning. A linear sponge (2) adhered with adhesive along the upper part of the housing (1) serves as an insulating element. This housing (1) also includes other slots (1-3) on its sides to allow the attachment of an extension adaptor (18) for the blind-cleaner housing (1) (see Figs. 39, 40, 41). This adaptor is similar in shape to the housing but of a smaller size, designed to be installed inside the housing (1) when it is shorter, or when a blind-cleaning unit of greater height than standard is required, or for packaging reasons. The extension adaptor is secured to the housing with screws. For the installation of the support (5) of the 4-in-1 blind-cleaning unit (0) on the blind guide or wall, double-sided adhesive tape (8) is applied to the base or side of the support (5). Once the adhesive is fixed, the support (5) is attached to the blind rail or wall and further secured with a screw (9) or plug and screw (6), as appropriate, ensuring greater safety and stability. This support (5) incorporates a trigger (4) attached via a pin (7) that allows oscillation of the cleaning unit (0) (see Figs. 35, 17, 18, 19, 20, 21). The retaining fins (1-2) stop the movement of the blind-cleaning support at the lower safety tip (5-5), limiting its motion (see Figs. 17-21). When the blind descends, the main spring (11) begins to operate, compressing and expanding, while the individual springs (12) move the self-supporting brushes (13) and the bristle brush (15) closer or farther apart depending on. The pressure exerted by each brush against the blind (16). The brushes (13) and (15) flex or straighten according to the force exerted individually, and the brush tips (13) and (14) include appendages (13-5) (see Fig. 26) or a plurality of appendages (13-6) (see Figs. 27, 17, 18, 19, 20, 21, 28, 29). These perform a secondary sweeping or drying action, sealing the blind more effectively against air, noise, and insect infiltration, thereby improving the airtightness of the system. Moreover, the appendage (13-5) or appendages (13-6) facilitate the change of direction of the brushes during the upward or downward transition of the blind by flexing smoothly upon contact with the edges of each slat (16) (see Fig. 29), resulting in smoother motion and requiring less counterweight for operation. To secure the brushes within the blind-cleaning unit (0), a double brush support (10) is used for PVC or wooden window frames, which typically have wider profiles than aluminium ones. For aluminium blinds, the double brush support (10) is shortened by half, becoming a single brush support (10-1) (see Figs. 10, 11, 12, 13). This support features elongated inner cavities (10-2) where brushes (13) and (15) are housed, allowing small movements depending on the pressure applied by the main brush spring (11) and the individual brush springs (12) against the blind (16). The main spring is positioned in the rectangular recess (10-4) of the brush support (10), ensuring controlled flexibility and automatic adjustment during operation. The individual springs are housed separately in the individual brush cavities (10-3) (see Figs. 14, 15, 16). This brush support (10) also features lateral extensions (10-5) that hold the brushes within the aluminium housing (1). When they come into contact with the retaining fins (1-2), they secure and permit free movement of the brush and spring assembly (0-2) within the housing of the blind-cleaning device (1) (see Figs. 17, 18, 19, 20, 21). These new brushes (13) are co-extrusions composed of a rigid material (13-1) such as plastic, aluminium, or another metal-joined to a flexible rubber (13-2) with a terminal appendage (13-5) or a plurality of appendages (13-6). This rubber includes equidistant holes (13-7) to improve adhesion of the sponges (13-3, 13-4) to the rubber (13-2), preventing displacement (see Figs. 22,23,24,25, 26, 27). These features also assist in the flexing of the brushes during directional changes, and by eliminating the traditional rigid body that held the brush, the design achieves greater lightness, flexibility, torsion, and independence. Figure 23 shows a brush (14) without co-extrusion, inserted into a rubber brush housing (14-1), which can be removed for cleaning or replacement. These brushes (14) have been enhanced with greater cleaning and insulation capacity by incorporating, at their ends, an appendage (13-5) or a plurality of appendages (13-6) (see Figs. 22, 26, 27, 29, 17, 18, 19, 20, 21). These appendages provide contact in areas previously unreachable, preventing the blind from raising while wet due to rain and stopping air currents, noise, and insects from entering the blind box. Because these appendages remain constantly in contact with the blind, together with the sponges and bristle brushes, the system now provides five protective barriers where previously there were only three. In a second preferred embodiment, in addition to all the components from the first embodiment, the brush (17) (see Fig. 28) is added to further prevent the entry of air currents, noise, and insects. In a third preferred embodiment, in addition to all the components of the first and second embodiments, an insulated blind box (16-1) (see Fig. 28) is used, resulting in a fully integrated insulation system for the entire blind. The present invention can be executed in various ways, allowing for modifications, additions, or removal of components, as well as variations in arrangement, shape, size, and the nature of materials, without altering the essence of the invention as.

Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claim 6, characterised in that the piece inserted into the insulation rail (1-4) of the housing (1) is a co-extrusion of a rigid material such as plastic, aluminium, metal, etc., and synthetic bristles, rubber material or sponges, said co-extrusion being able to be replaced by other means such as a spongy insulating material with adhesive.

9. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claims 1 and 6, characterised in that the Full Kontact system comprises a housing (1) inside which a brush-spring unit (0-2) is installed. It comprises a double brush support (10) or a single brush support (10-1), a main spring (11), and a plurality of individual springs (12), as many as brushes (13), (14), (15), and depending on the material from which the guides of the blind are made, a double brush support (10) will be used, which has different heights; if these guides are made of wood or PVC, it will be installed without cutting; if the material from which the blind guides are constructed is aluminium, this double brush support (10) will be cut, becoming a single brush support (10-1). This brush-spring support (10), (10-1).

10. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claims 1 and 9, characterised in that this double brush support (10), or single brush support (10-1), has a rectangular shape with lateral extensions (10-5) that keep the support, the brushes (13), (14), (15) and the springs (11), (12) inside the aluminium housing (1), allowing their free movement without them coming out. This double brush support (10), or single brush support (10-1), has a rectangular opening (10-4) for housing the main spring (11). Likewise, there are a plurality of rectangular openings (10-3) for the individual springs (12). Above the individual rectangular openings of each spring (10-3) there are elongated openings (10-2) where the brushes (13), (14), (15) are installed, allowing them a small upward and downward movement without being able to come out, because the opening of these elongated holes (10-2) is smaller than the co-extruded body of the self-supporting brush (13) or the brush housing (14-1). However, it allows linear movement inside them of the brushes pushed by each individual spring, thus achieving greater precision and independence in the distance and force of each brush.

11. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claims 1 and 10, characterised in that the main spring (11), which has a greater travel and greater force, has the function of exerting pressure against the blind (16), while the individual springs (12) have a shorter travel and a lower force than the main spring (11), their function being to absorb and dampen the possible excess pressure produced by the main spring (11).

12. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claims 1, 10 and 11, characterised in that the self-supporting brush (13) is constructed from three different materials: a co-extrusion (13-1) of a rigid material such as plastic, aluminium, metal, etc., which provides rigidity and lightness to the brush, and a rubber body (13-2) which gives flexibility to the brushes during the changes of direction of the blind. It also has sponges attached for sweeping (13-3), and on the opposite side of the rubber a polishing brush (13-4). Between these sponges there may protrude an appendage (13-5) or a plurality of appendages (13-6), which are extensions of the rubber body (13-2). This rubber body (13-2), (14-2) may include a series of equally spaced holes (13-7) arranged longitudinally along the rubber body, which help the brush to flex during the changes of direction when the blind moves down or up by creating a critical bending point. This brush (13), (14) has, during more than 99.9% of the time, two different materials with different functions in contact with the blind, either a sweeping sponge (13-3), a drying or polishing element (13-4), and an appendage (13-5) or a plurality of appendages (13-6), thereby improving the cleaning and insulation of the blind. The brush without coextrusion (14) differs from the self-supporting brush in that the coextrusion of rigid material is replaced by an independent housing (14-1) made of a metallic material, aluminium or plastic, etc., maintaining all the other characteristics of the self-supporting brush (13). In this way each brush (13), (14), (15) achieves greater flexibility and independence in its movements, these springs being able to be replaced by other means such as springs, magnets, etc.

13. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claims 1 and 12, characterised in that the bristle brush is a co-extrusion of a rigid material and bristles. These brushes (13), (14), (15) may be combined, and their distribution and number may be changed.

14. Automatic blind-cleaning device 4-in-1: automatic blind cleaning, thermal insulation, acoustic insulation and insect barrier, according to claim 1, characterised in that, for improved thermal insulation, acoustic insulation and insect barrier of the blind box (16), and consequently of the dwelling, a brush (17) made of sponge, rubber, bristles, etc., is installed on the inner side of the blind in its upper part. Insulated blind boxes (16-4) may also be included in order to provide total insulation of the blind.
