Description

Curtain with filter system.

Introduction

The object of the present invention relates to a new curtain system, for installation in windows, which pursues the objective of preventing the entry of light into the room without preventing the entry of air and, consequently, allows the ventilated room being dark.

Normal blinds meet the objective of letting the air in when they are ajar and yet they don't meet the condition of providing the desired darkness to to fall asleep

This system can be installed in any type of window to complement the normal blinds of slats horizontals that, in most cases, are needed by safety reasons. It allows a total opening position and any intermediate position, although logically fulfills its function when fully deployed, that is, covering the entire from the window hole.

Sector of the technique to which the invention relates

The invention presented affects the Sector of Fixed Constructions, chapter of Public Works and Buildings in concerning roller blinds, in general, affecting, from the industrial point of view, in the manufacture of blinds and of complements and accessories for the filtering of light in doors and windows

Background of the invention

There are numerous backgrounds in the field of the blinds for regulation of air and light entry into doors and windows of all kinds of buildings and even for the enclosure physical of these gaps without prejudice to allow such entry of light and air There are solutions to regulate the entry of light based on curtains, blinds or blinds with articulated slats. There's also solutions to allow the gradual entry of light and air or sliding shutters, with their guides included, to present an incidence almost perpendicular to the sun's rays on days of High temperatures and great luminosity.

However, there are no known solutions that allow adequate aeration of a room so simultaneous to maintaining total darkness in it which is a desirable condition in the case of most people When they want to fall asleep.

The object of the present invention is to cover that lack with an innovative solution that can be installed in any type of window as a single solution or as a complement to the classic type of roller blind slat.

Description of the invention

The present invention, as it has remained exposed in the introduction, refers to a new type of curtain, for installation in windows, which being fully deployed prevents the entry of light but allows aeration of the room. The system can be installed in any window complementing other existing devices such as, for example, the traditional roller blind. Is thinking especially for climates where it is advisable to keep constantly aerating the rooms, including night periods The main element of the invention consists of in a vertical roller tape arranged in four layers of such that the tapes of each layer overlap with the tapes of the adjacent layer with a degree of overlap such that they prevent entry of light being all of them totally opaque. Each of the layers It is formed by a series of ribbons of a width that can be between about 6 and 20 cm. that, at the top of the window, are rolled on a roller that also fixes the position of each lama with respect to those at his side. In the part The relative position of the belts is also secured regarding collaterals because there is a horizontal stringer with a series of slots through which each blade is introduced and fixed. To the be four layers, it is understood that the set has four rollers at the top, that is to say in what is normally known as blind box. In the same way the horizontal stringer Bottom has four rows of parallel grooves conveniently distanced to ensure the position of the whole set of tapes With this provision, with the help of a handle manipulation, opening and closing, it is possible to completely hide the tapes in which we can call curtain box, or deploy them completely and leave them in the work position which is a position in which the tapes are tensioned thanks to the springs of recovery of the rollers and to the locked position of the horizontal stringer whose bolt is inserted into the frame of the window. In that position the light is prevented from entering the room but, nevertheless, the free circulation of the air through the existing holes.

To prevent the entry of mosquitoes or insects in the room, a mosquito net is planned sufficiently dense in sliding frames. On the other hand and such as previously mentioned the system is compatible with a classic roller blind that is located in the part outside of the window assembly.

Description of a preferred embodiment

Curtain with filter system (Figs. 1 to 5) consisting of a curtain based on vertical opaque tapes that, being fully deployed, prevents the passage of light but allows the ventilation of the room where it is installed and that in an embodiment preferred by the inventor consists of a module (1) that contains as a main part a series of tapes vertical (3) of totally opaque material of a width between about 6 and 20 cm. that covering the entire height of the window is rolled into four rollers (8) that are installed in the so-called curtain box (2). The tapes (3) are arranged in four layers that fit into a crossbar (4) equipped with a series of slots whose arrangement is represented in (4.1) (Fig. 3). In it (Fig. 3) it is observed that the tapes of the first layer (3.1) are also arranged that those of the fourth layer (3.4) as well as those of the second layer (3.2) with respect to those of the third (3.3) and together form a curtain of ribbons (3) that prevents the passage of light towards the interior of the room. This requires that the curtain be fully deployed by pulling down the crossbar transverse (4) that by means of closing bars (11) fits in the anchor cylinders (6) located on both sides of the window and in its lower part. The tape assembly (3) is tensioned by the antagonistic force exerted by the internal springs of each one of the rollers (8), the opening of the curtain being possible by actuating the handle (5) that may be in the position of closing (5.1) or opening (5.2). A simple mechanism fits the locking rods (11) in the anchor cylinders (6) by turning the handle (5). The tensioning springs of the rollers (8) make tape recuperators (3) in the process of opening the Curtain that easily rolls on the rollers (8).

For a better understanding of the disposition of tapes (3) has been included (Fig. 4) representing a view of profile of the four rollers (8) with their corresponding tapes (3.1) (3.2) (3.3) and (3.4), which in their lower part are inserted in the crossbar (4).

Fig. 5 is related to Fig. 4 as schematically represents the mechanism installed on the tip of the rollers (8) to produce the simultaneous turning movement in all of them with proper direction of rotation to the position of each roller. At the end of each roller (8) and integral with each one of them respectively, the gears are mounted (12.1) (12.2) (12.3) and (12.4) that rotate driven by movement vertical up and down of a special zipper (13), which by means of a tie bar, not shown, is linked to the crossbar (4). From the observation of the Fig. 5 it is easy to understand the operation of the mechanism that spins gears (12.1) and (12.2) in one direction at the same time that the gears (12.3) and (12.4) rotate in the opposite direction which is necessary so that the tapes (3.1) (3.2) (3.3) and (3.4), are move in coordination when a person, acting from the handle (5), raise or lower the crossbar (4) with a view to opening or close the curtain of the present invention. In the same Fig. 5 it has represented the curtain box (2) and its relative position with respect to the blind reel (9).

There are another series of auxiliary elements necessary for the assembly of the curtain module with filter (1) that have not been represented because they are not essential for the perfect understanding of the concept of the invention. Among them you could cite the arrangement of the supports, the reels with recovery springs, the tie down system of the belts (3) to rollers (8) and crossbar (4) and other details of external finish

It has been included, however, in Fig. 1 and Fig. 2, the detail of the positioning of the mosquito net (7) with frames sliders and the detail of the relative situation of the blind Traditional horizontal slats (10) that do not require explanation special.

It is not considered necessary to make the content of this description for a subject matter expert can understand the scope and advantages derived from the invention, as well as develop and implement the object of the same. However, it should be understood that the invention has been described according to a preferred embodiment thereof, whereby It may be subject to change without affecting or suppose any alteration of the basis of said invention. Is say, the terms in which this description has been exposed preferred of the invention, should always be taken with character Broad and not limiting.
