Abstract

Clean exterior automatic blinds that clean always in three phases simultaneously: i) Sweep solid waste, ii) Wet and iii) Drying and consisting of a roller sponge coated (11) moistened and two double brushes flexible (8), made of flexible rubber and at the end they carry adhered by a spongy material face (10) and by the other rough material (9) in such a way that they sweep on one side and dry on the other as the blind is lowered or raised and they are crimped to through a housing (14) of a plastic housing (12). This plastic housing (12) is located inside another housing external (13) that rests on a system of hollow columns lateral, as lateral guides, for fast and safe assembly and disassembly in the equipment maintenance process.

Description

Clean automatic blinds.

Object

The present invention relates to a mechanical device capable of cleaning the external part and maintaining also clean the inside of the blinds, closures of shops, garages and awnings that have the same mechanical principle, during the same process of raising and lowering them using a sponge roller system and two brushes doubles, which are inside housings and that are supported by two lateral columns for easy assembly and disassembly of the cleaning equipment on the upper external part of the shutter, for cleaning.

Technical sector

The invention is in the technical sector washing or domestic cleaning, more specifically in relation to Cleaning blinds and awnings.

State of the art

There is currently no effective system for to be able to clean the blinds on the outside, the systems manuals are very difficult to carry out and pose a danger considerable.

They have previously been patented different inventions aimed at solving the cleaning problem external blinds as is the case of patent ES2153731 which discloses a cleaning system for the outside of the shutter using a mobile roller geared with a drum and the ES1038501 patent disclosing a blind cleaning system to through a rotating brush. In the cleaning processes known so far, solid waste cannot be avoided reattach to the blind or make the cleaning roller dirty and the duration of the cleaning liquid is very short due to the losses caused by evaporation and poor dosing of same.

After analyzing the different external cleaners of blinds, it has been observed that there are great difficulties for remove solid waste and keep the roller moist as well such as the number of pulleys and gears needed for the rotation of the roller, the short duration of the cleaning liquid and the difficulty and danger posed by the placement, assembly and disassembly of These mechanisms for maintenance.

Detailed description of the invention

With the present invention a large improved performance when lacking pulleys and gears with the consequent saving of time and money in its assembly and maintenance, as well as an increase in effectiveness and efficiency in the  cleaning, by not coming into contact with the blind the waste initially eliminated, and an improvement in durability and speed of said cleaning, when the sponge, container roller acts, dispenser and liquid supplier. When the roller is covered with sponge, it does not drip when the blind goes up or down, it gives you the right amount of cleaning fluid avoiding rivers of cleaning liquid as well as staining the inside of the shutter, while saving liquid, by not wasting it.

For this, the present invention focuses on the use of one or a plurality of double flexible brushes, that allow the cleaning process to be deeper, improving both the efficiency and the efficiency of cleaning, and of a roller embedded in a housing semi-hermetic of an internal plastic housing, PVC, aluminum, etc., protected by another outer shell, which considerably increases the insulation of the outside roller, reducing the evaporation of the cleaning liquid and that being sponge can get wet for several days with single dose

The present invention offers the elimination of pulleys and gears, a saving of cleaning liquid and an improvement substantial in cleaning, allowing cleaning to take place in three simultaneous phases, each time the blind is raised or lowered: 1st waste disposal, 2nd application of cleaning liquid and 3rd dried

This system manages to prevent them from being introduced solid debris in the wet roll with the consequent mud formation, thanks to the use of double brushes Longitudinal flexible, the same length as the slats of the shutter, made of rough material on one side for the waste disposal, and spongy material on the face opposite for drying, and joined by a flexible material (rubber or similar) that prevents the liquid from mixing with the powder avoiding Mud formation Also, the use of a single roller covered with sponge that is dripping wet from the top of the roller, and that absorbs inside the cleaning liquid, insulated by a plastic housing and an external aluminum, allows to reduce considerably the loss of liquid by evaporation and, consequently, keep the roller moist for more time. The roller sponge acts as a container, dispenser and supplier of the cleaning liquid to the blind. Roller rotates by direct friction with the blind.

The easiest and most economical way to do the The present invention is to place a minimum of 1 double brush parallel to the blind, improving its effectiveness with a greater number of brushes and supporting these through a rack of aluminum, pvc etc., attaching to the frame or the wall of the window in the external upper part of semi-fixed form, by means of fixed parts, which allow to release the cleaning equipment with a mechanism, of the frame of the blind. Optionally they could be provide parallel columns for assembly and disassembly, more fast and safe. This team would be characterized above all by the absence of rollers and side columns with the consequent Thinness of the equipment.

Another way of carrying out the invention is to mount the cleaning equipment (3) semi-fixedly in the frame of the blind with a system that uses parts that are mounted fixed on the frame or on the wall of the blind in the part external upper and that by means of a mechanical system, allow to release the cleaning equipment (3) of the parts that are fixed in the frame of the blind. This system would lack columns, and others pieces, so that the product can be cheaper.

The most perfected way to carry out the invention and on which a more extensive explanation will be given and Detailed includes parts, shapes, materials, and more concepts important for its most efficient operation. Additionally, for help the easy placement, disassembly, maintenance and cleaning of the equipment, this one is inserted to the blind together with two columns with hinged doors that act as a hinge guides, being able to be these columns and doors in different ways, to fit the equipment into position and allow it to slide for its extraction. This system, in new construction, prevents enter mortar inside and also allows you to put a fence in the window without affecting its operation. The columns they house inside a formed anti-fall system by a rope and a dustpan that inside has a strap metallic and works in the same way as a flexometer, which joins one of the columns to the cleaning device, to avoid the possible fall to the street, and the other column to the supply tube of cleaning fluid with the non-return valve for avoid gravity loss by injecting the cleaning liquid. He system to raise the cleaning liquid can be electric, mechanical or hydraulic, or a mixture of these. To help the easy assembly and disassembly of the cleaning equipment by the columns, we take advantage of the blinds, since these will withstand the cleaning equipment inside the guides preventing it from falling, in the moments that have to move the cleaning equipment for your cleaning or maintenance up to an approximate height of 1.50 m or raise it approximately 2.10 m in its usual position. For favor the descent of the blind, the stops of the blind of an additional ballast to favor its descent and counteract the friction produced by the brushes and the roller; likewise a kind of dove is used that surrounds the head of the screw to avoid having to use any tool for assembly and disassembly of these stops.

Daily cleaning of the outside of the blind, allows us to also keep the internal part clean, and that 90% of the dirt accumulated in the internal part is due to that when the blind is dirty on the outside and begins to roll up in the drawer, the inner part of the blind is supported on the outside and part of the dirt is transferred from the External part to internal.

Also the present invention improves substantially the insulation by greatly reducing the space between shutter and blind box when using the brushes and barrier roller.

In a first preferred embodiment, the blind-cleaning equipment set (1) consists of a cleaning device (3) that is inserted inside two columns (4) supported by the doors (5) to ensure their correct positioning in the upper external part of the blind (2). Inside the right or left column is the cleaning liquid insertion tube (6), which carries a non-return valve (19), anchored to the column guide, (4) one end goes outside for injection by syringe, this system can be replaced by any other that allows us to raise the cleaning liquid without effort either electric, mechanical, pneumatic or hydraulic, or a mixture of them and whose upper end joins the tube that connect from the top to the cleaning equipment (3) is inserted into a cavity intended for it of the inner housing of plastic (12), and having a longitudinal groove (15) in which locate a cloth (16) or similar as a filter as you can see in figure 6, which is inside the housing internal (12) and which is the one that houses inside the roller with the sponge (11) that will absorb the cleaning liquid contained in said tube. The cleaning equipment (3) consists of an external housing (13) with a regulating screw (7) that is responsible for regulating the position of the inner shell (12), which is in the inside the outer casing (13), with respect to the latter for thus being able to regulate the friction of the brushes (8) and the roller (11) against the blind (2); Fig. 5 shows two positions ends of the housing (12) according to the situation of the regulator screw (7). This regulation system can be replaced by springs, straps, magnets that repel etc. The internal housing contains a cavity where the end of the tube (6) and the cleaning liquid inserted through said tube. The liquid falls to the sponge of the roller (11), through the hole longitudinal (15) installing a rubber filter (16) or textile fibers in said groove to favor controlled dripping to along the sponge roller (11), this acts as a container, dispenser and supplier of cleaning liquid to the blind. The internal housing (12) also contains two ends as tweezers (14) Fig. 6 that serve as housing and attachment point for the brushes (8) with some clearance to allow movement towards up and down the same as well as in and towards outside to facilitate the torsion of the brush in the changes of sense. On the sides of the inner shell are some caps with some lugs for accommodation and sliding inside of the outer shell caps. The brushes are made of flexible rubber or similar, to allow bending movement up and down and at the end they have attached, joined or sewn, as shown in figure 3, two types of Materials: rough material (9), such as rough rubber, fibers textiles, or sponge for solid waste disposal, and spongy material (10), such as spongy rubber or textile fibers, for drying the blind. The upper brush is placed with the rough material (9) facing up and the lower brush It is placed with the rough material (9) facing down. One or both faces can be impregnated with some special liquid to perform its function better, such as sponges that they clean the shoes, which are subjected to a treatment that attracts the dust The purpose of this system is to always be clean and dry the blind once it has gone through the cleaning equipment, already it is lowered or stored, and that no residue enters inside of the plastic housing (12) as well as keeping the roller sponge (11) as isolated as possible to retard evaporation of the cleaning liquid located inside. The way and constitution of brush materials, does not allow mix the liquid with the dirt when placed in the middle of the material rugged and fluffy material, the flexible rubber that makes barrier between the two, preventing mud from mixing and forming since otherwise we would stain the blind (2). To favor the lowering of the blind, the blinds (17) are provided with a metallic ballast to make it heavier and counteract friction produced by brushes (8) and roller (11).

Detailed exposition of the operation of the first preferred embodiment of the invention

The cleaning equipment (3) works at the moment in which the blind is raised or lowered (2). When the shutter (2), as can be seen in figure 4, the brushes (8) flex, initially acting the material rough (9) sweeping all existing waste. Subsequently supply the cleaning liquid with the roller (11) and finally dried with the spongy material (10). When the blind is lowered the same process will be carried out, in the same order but in this case, it is the rough material (9) of the upper brush that sweeps, subsequently the cleaning liquid is supplied to the blind with the roller and dries with the spongy material (10) of the brush lower. In this way three jobs are done in it instant, simultaneously: sweep, supply liquid cleaner and dry. By using two brushes you get one deeper cleaning, and does not allow the blind when roll this soaked as it would easily attract dirt and it would pass it to the inner part of the blind, when the liquid cleaner evaporates our brushes and roller follow working by trapping dust and preventing the accumulation of this on the blind, thus distancing the supply of cleaning liquid once a month, more or less. How we usually go down the blind once a night and raise it once in the morning, we will be cleaning the blind more than 700 times a year without any danger or effort.

The replacement of the cleaning liquid is carried out in an extremely easy, fast and safe way, with a syringe we will introduce the cleaning liquid into the valve non-return (19) that connects to the tube (6), which communicates with the internal housing (12) and consisting of a filter (16) that doses the drop of the cleaning liquid along it so that drop drops dropwise on the sponge roller (11) to absorb it, "yes this fall quickly would not be absorbed by the roller with the same efficiency since much of the liquid would slip and I would lose. "

The maintenance of the equipment is very simple, fast and safe for this we will use the columns sides (4) and blinds stops (17) as elements fundamental for the assembly and disassembly of the cleaning equipment. When the cleaning equipment (3) is supported on the two doors (5) of the hollow columns (4). to uninstall the computer (3) only the blind must be raised until the stops (17) of the blind touch the equipment Fig. 7 sequence 2 and open the doors (5), Fig. 7 sequence 3, so that the cleaning equipment can descend, (3) next to the blind, when you lower it, until you reach a stop located at the doors (5) of the column (4), Fig. 7, sequence 4, in that moment the blinds of the blind (17) are removed and this is raised, being in our sight and reach the cleaning equipment (3), Fig. 7, sequence 5, the cleaning equipment (3) is removed from the columns (4) pulling a little from the side up and drawing this towards self and releasing the safety rope (20) Fig. 7, sequence 6, without danger and without any tool in less than 1 minute. The cleaning team is taken to the bathtub for cleaning. For the installation of the equipment, they are made the same operations but in reverse. To regulate the friction of the  brushes (8) and roller (11) against the blind (2) are arranged of a screw (7) with a threaded head for use manual, which allows you to adjust the internal housing (12) to the type of window and regulate the pressure of the brushes (8) and the roller (11) so that they exert adequate pressure on the blind (2). So the same equipment contains a security system to avoid fall to the outside, consisting of a returnable rope (20), subject to a collection system (21), installed inside a of the two hollow columns (4), and the other end attached to the equipment cleaner (3).

In a second preferred embodiment, devised to put the invention into practice in the easiest way and economic, a minimum of a double brush (8) is placed parallel to the blind (2), improving efficiency with a greater number of brushes and supporting these by means of a rack of aluminum, pvc etc. (not shown in the Figures) The team of cleaning is attached to the frame or the wall of the window in the part upper external of this one of semi-fixed form, by means of some pieces fixed, allowing to release the cleaning equipment, by means of a mechanism known in the art, of the blind frame. Optionally, parallel columns can be provided for mounting and disassembly faster and safer. This team would be characterized especially due to the absence of rollers and side columns with the consequent lightening of the whole window blinds,

In a third preferred embodiment of the invention, the cleaning equipment (3) is mounted semi-fixedly in the frame of the blind with a system that uses parts that are mounted fixed on the frame or on the wall of the blind in the part external superior and that through a mechanical system known in the technique, let loose the cleaning equipment (3) of the parts that they are fixed in the frame of the blind (2). This system would lack of columns, and other pieces, in order to lower the product.

The present invention can be carried out. in different ways, with some modifications, and deletion or increase in the number of pieces, varying the arrangement, the shape, size and nature of materials without being altered  the essence of the invention, which is claimed below.
