Description

INSTALLATION FOR MOTORIZATION OF BLINDS

OBJECT OF THE INVENTION

The present invention relates to an installation for the motorization of blinds, intended to be able to carry out the motorization of an existing conventional blind, with concealment of the power supply cable for the corresponding drive motor, from the actuation switch of such engine, until the latter.

The object of the invention is to eliminate the friction that it is necessary to make in the motorization of a blind to carry the cable from the switch, taking advantage of the gap that remains in the aluminum frame by removing the conventional tape picker, to the motor

BACKGROUND OF THE INVENTION

As is known, the upper drawer of a blind includes a lower groove through which the blind comes down, guided perfectly through two U-shaped side profiles of facing openings, said profiles being stiffened so that in addition to forming the guide in "U", they have a closed tubular core that is the one that provides stiffening to the guide.

On the other hand and as it is also known, the drawer of a blind is oversized in length with respect to the width of the blind itself, so that the axis of the winding drum is longer than the slats, axis that on one end is It ends in a support beam on a support established for this purpose on the side of the drawer, while at the other end the shaft receives the corresponding pulley on which the belt or drive cable is wound, whose other end is wound on a collector located at a level significantly lower than that of the drawer, so that the winding / unwinding tape of the blind, between said collector and the winding pulley or drum, runs frontally in proximity to the wall and logically seen in front of it.

In the case of a cable being the winding element, instead of a dustpan, what is there is a crank that acts on a reel with brake on which the cable is wound, which runs along the wall in a recessed tube.

Well, when it comes to motorizing a blind, where the upper pulley was placed, the corresponding motor is placed, being governed by a double switch that is located in correspondence with the location of the belt picker, a switch that is double to raise and lower the blind. With said double switch, two race ends work, which stop the motor in the opening and closing of the blind.

In the case of motorizing an existing blind whose drive is by cable, the same recessed tube for the drive cable, is used for the electric motor power cable, although this type of blind is very rare, as normal is that are tape driven.

Obviously, since there is no channeling in the type of roller-actuated blind, when the motorization is carried out, it is necessary to make a touch on the wall to hide the electric cable that connects the switches located in correspondence with the collector hole with the drawer of the blind itself, and more specifically with the motor located above the drawer to drive the winding / unwinding axis of the blind.

It is evident that the realization of a brush to hide the electric cable, carries with it a series of problems and inconveniences, such as having to carry out the covering of the brush, repainting the wall or at least that area, which it would not be homogeneous with the rest of the wall, etc.

At the same time and with the double switch of the invention, the gap left by the belt collector is used, replacing it with the double switch and measures corresponding to the gap left thus avoiding having to recess a wider conventional switch.

DESCRIPTION OF THE INVENTION

The installation for motorization of blinds that is recommended, has been conceived to solve the problem previously exposed, based on a simple solution but of great efficiency.

More specifically, the installation of the invention is characterized in that the electrical cable that is necessary to be disposed between the switch and the motor for driving the blind, or what is the same between the recess of the collector of the conventional blind and the drum of such shutter, runs inside one of the vertical guides of the blind, and specifically through the stiffening tubular core of said guide, so that as that guide profile flows directly into the drawer, the electric cable will also flow into the drawer, allowing its connection to the corresponding drive motor that will be located at one end of the winding / unwinding axis.

In this way, it is not necessary to make rubs on the wall, since the cable is hidden by the guide and in the worst case, only a short section of it is visible, which is the one that separates the switch from the guide, space that in many cases is practically non-existent since the collector is mounted practically attached to the guide.

In the event that there is that small distance between the switch and the guide, the section of friction to be made is minimal, being easily concealed.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a schematic representation according to the front elevation of an installation for motorization of blinds made in accordance with the object of the present invention.

Figure 2.- Shows a detail of the flow of the electric cable through the closed tubular core that forms part of the lateral guide profile for the louvers of the blind.

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the installation of the invention comprises, as is conventional, a drawer (1) where the corresponding drum (2) for winding / unrolling a blind determined by a plurality of slats (3) is established. , these running along their ends in corresponding lateral guides (4) in "U", facing each other and which at their upper end flow into the corresponding drawer (1).

The winding / unwinding shaft (5) rests at one end (6) on a support (7), while the opposite end of that shaft (5) is mounted on the corresponding drive motor (8) for winding / unrolling the blind itself, when the blind has been or is motorized.

The motorization is carried out by means of the motor power supply (8), through a mains power cable (9), and a cable

(10) through which the operation of the motor (8) is interrupted or activated, whose cable (10) is arranged between a double switch (11) located at an appropriate height and of exact measurements or adaptable to the gap left by the belt collector, and the motor itself (8), with the particularity that such cable (10) runs through the inside of the corresponding lateral guide of the

shutter, and more specifically on the tubular and closed core (12) of the corresponding guide profile (4), as clearly shown in Figure 2, so that from the switch (11) which is double, one for rise and another for lowering, that is, for opening and closing respectively of the blind, the cable is immediately inserted into the sliding guide of the blind, and specifically in the closed tubular portion (12) of said guide (4), until the motor is reached (8); as it is clearly represented in figure 1, thus hiding that electric cable (10) and in the worst case with a minimum visible section that could be simulated very easily because

10 the double switch (11) is located very close to the guide itself (4).

In this way it is possible to automate a blind without any problems and without works, since avoiding having to make rubs as traditionally happens since it is enough to place the switch (11) on the

15 classic collector of the blind tape, and to pass the cable (10) from that switch (11) to the motor itself (8) located on one of the ends of the roller winding / unwinding axis (5), without any other type of operation or components.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The invention relates to an installation for motorization of blinds. In the preamble of the only claim present in the application, usual steps are proposed in the process of converting a manual blind (with tape for winding / unrolling, pick-up in a wall recess and lateral guides), characteristics widely used in the state of the art, in motorized blind, consisting of replacing the following elements: -the pulley with an electric motor and the collector with a double switch. D01 has been considered as the closest document of the state of the art and it shows the following technical characteristics corresponding to the characterizing part of the claim (the numbers in brackets correspond to this document): -the cable that runs between the corresponding double switch and the motor is passed through the closed tubular core corresponding to the profile of one of the lateral sliding guides (4) of the slats (see figures 1 and 3): although it is true that in D01 the cable is not It is between the switch and the motor but between the motor and a solar battery, the objective is the same, avoid rubbing on the wall when wiring in a motorized blind (paragraph 0009). -which is completely hidden until the blind drawer is reached: in figure 1 it is observed that the cables leave from an element in the blind's own drawer and that they go to the battery that is in the guide itself, so in no moment they leave said guide of the blind. - it being provided that said double switch has dimensions according to the gap left by the tape collector: this characteristic is not reflected in D01, but it is considered obvious to a person skilled in the art, that if the objective is to perform the least masonry work on the wall, choose, from the range of switches of different dimensions offered by the market, that more similar to the gap that we have already made in said wall. Therefore, it is considered, in view of D01, that the claim raised by the application does not imply inventive activity. Likewise, and for very similar reasons, document D02 also annuls the inventive activity of the claim. This document attempts to improve the operation and use of wiring from the existing motor in the drawer of the blind to the switch. Although the problem posed in D02 is to ignore an existing vertical element in the wall and not avoid rubbing, it definitely seeks not to make holes in the existing wall, using the same solution as the request, to pass the cables (28 ) by a closed space corresponding to the blind guide (see figures 10-12) until reaching the switch (29b), so, as already said before, this document also cancels the inventive activity of the claim.
