Description

Cushion for blinds.

Introduction

The damping device for blinds that described herein, it is an invention that complementing the usual installations of blinds or closures Rollers existing in homes, factories, offices, etc. Y by adding some elements, it allows to avoid the annoying vibrations accompanied by noise produced by the wind.

The essential idea of the invention lies in the installation of the damping device on the premises usual blinds so that, optionally, you can unfold the shock absorber by applying it to the surface of the shutter preventing the movements of their slats as a result of the action of the wind. This can be especially useful in night periods avoiding shocks or discomfort during the dream.

Sector of the technique to which the invention relates

The invention presented affects the Sector of Fixed constructions and specifically to the chapter of elements of closure and roller blinds in general, directly affecting in the industrial blind manufacturing and installation sector of them in buildings of all kinds.

Background of the invention

In the present times everything related to the construction of buildings and homes is developed with absolute speed as this sector has long been a Great driver of the economy. It is normal, therefore, that you also quickly develop many innovations related to complements for homes either to improve yields in construction work, to reduce the cost end of the works or to improve the overall quality.

With regard to protections and closures for windows and doors, the innovations have been numerous, passing in a short time the windows protected with roller shutters from wooden slats to blinds with plastic, aluminum slats, or light materials. This achieves a lower expense of maintenance regarding wood very sensitive to moisture and Adverse weather conditions. It is also important the lightening in weight for both manual drives and for the motorized

Notwithstanding the use of these materials, undoubtedly, it has numerous advantages, it involves several inconveniences such as facilitating intrusion or favor vibrations in cases of windstorms which it can be particularly annoying at night preventing the sleep reconciliation Against the intrusion the solution more frequent is the placement of security bars that always They are unsightly and of considerable price.

Against the vibrations it is difficult to remedy because, for a smooth sliding of the slats along the guides, it is not convenient that they remain very tight and if it is tried to do so what usually happens is that the adjustment of a slat with the slats worsens adjacent which means an imperfect closure and acoustic insulation losses and
thermal.

Well, the author of the present invention, aware of the numerous inconveniences of current systems and with the aim of introducing an innovation, of affordable price, which reports several advantages, and that, above all, It is applicable to any of the current blind systems and roller closures, has developed the following invention, totally new, which basically requires complementing the installation of any existing blind with a simple device that restricts the movement of the slats and, in Consequently, the noise produced by its vibration.

Description of the invention

The present invention relates to a new blinds damping system that, taking advantage of any existing installation and with the only addition of the device that has invented the author achieves the cushioning of the possible vibratory movements of the slats caused by wind or by resonant phenomena of any origin.

The basic idea of the invention consists in apply a spongy band, foam type or similar, on the blind that you want to preserve from possible vibrations.

The aforementioned band is supported by a ribbon mobile that tilts on another fixed bar through some flat bars The set acts like a pantograph in such a way that You can basically present two positions: the folded position or  rest and deployed or work position.

In the folded or resting position the two slats are positioned next to each other so that the elastic band located on the mobile slat, stays away of the louvers of the blind without affecting its normal operation and  allowing all kinds of movements including vibratory Causes of noise For its part, the fixed bar is rigidly attached to the window frame, either screwed to one of its vertical uprights or, in another alternative, by means of two suckers that adhere directly to the crystals.

In the deployed or working position, the two slats are far apart but always related by the joining plates. The fixed bar continues logically in the same position; instead the mobile ribbon, because to the pantograph effect, it presents its face with foam applied on the slats of the blind, exerting slight pressure on these, causing their consequent immobilization and preventing Get into vibration. In this work position you should not move the blind for opening or closing as they can occur harmful effects even if they are not serious.

Thus, in the event that it is intended to raise the shutter acting on the corresponding tape or crank of drive the damping device will tend to fold exerting a friction action between the elastic foam band and the slats of the blind. On the other hand, in the event that it is intended lower the blind, the damping element of the invention will tend to stick against the slats by exerting brake and deteriorating the flexible band

As will be seen more clearly in the figures, the mechanism formed by the two slats, joined by two or three plates, always keep the two slats mentioned in permanently parallel positions even if their distance goes varying from a minimum null value defined by mutual contact, up to a maximum value that will depend on the length of the flat bars

The plates, of rectangular section are all same and the fixed and mobile slats also have a section Rectangular same in both presenting the mobile ribbon a total length greater than that of the fixed bar.

It is clear that the invention here is presents is especially suitable for cases where shutters have a considerable width since in those circumstances the cimbreo effect is more likely to occur which causes vibration and consequent noise. In those cases the device of the invention should be placed in an upright that found in the vicinity of the midpoint of the width total.

It is also evident that its application is logic for blinds that are in an intermediate position closing or total closing as a blind fully raised it is not subject to the actions of the wind or any other that It may cause noise.

In case the windows do not have intermediate uprights, the application of the device of the invention in the crystals themselves by means of two suction cups that They allow the placement of the device where it is most convenient.

Description of a preferred embodiment

Cushion for blinds (1) (Figs. 1, 2, 3 and 4) intended to prevent vibratory movements of the slats of the traditional blinds as a result of wind action or of any other cause that produce annoying noises in any moment and especially during the night or periods of sleep.

According to an embodiment preferred by the inventor, the shock absorber (1) is constituted by the set of a fixed slat (2), a movable lath (3), some plates (4) and a flexible band (5) attached to the mobile strip (3).

The plates (4) in number of two, three or more, they are destined to unite and relate to each other the fixed ribbon (2) with the mobile bar (3). This is produced by means of axes that join each plate (4) with the fixed bar (2) by one of its ends and with the moving slat (3) at the opposite end. In these conditions the set behaves like the structure of a pantograph in which the fixed (2) and mobile (3) slats adopt a series of positions staying parallel to each other.

The fixed bar (2) is named like this because it is intended to hold firmly on the vertical uprights of any window, and especially on the intermediate uprights (7) (Fig. 3) by means of screws, screws, glue, or any other system That way the mobile ribbon (3) can move keeping its longitudinal axis in an upright position being able to adopt two main positions. One of them is the folded position in which the mobile slat (3) is adjacent to the fixed (2) and the other is the deployed position in which the mobile slat (3) moving away from the fixed (2), approximates the blind (6) whose vibration we want to dampen. To facilitate said damping, the mobile strip (3) is equipped with a flexible rubber band, foam, or any other material of Spongy and slightly deformable nature.

Figure 3 shows the operation of the damper (1) showing its two main positions, the folded and unfolded.

For the up and down movements of the shutter (6) the shock absorber (1) must be in the folded position, reserving the deployed position for the moments when, being Lower the blind, totally or partially, you want to avoid Possible noise and vibration.

In view of Figure 3, it is understood that when the shock absorber (1) is deployed it is not convenient to move the shutter (6). However, movements will be possible. ascending the blind (6) as the friction itself with the flexible band (5) would cause a slight folding of the shock absorber (one). Instead the downward movements, with the blind (6) to half way, they would cause a tendency to wedge the device with possible damage to flexible band (5), shock absorber (1) and even blind (6).

Therefore the inventor does not rule out the possibility to install a detector that indicates the position at all times of the shock absorber in order to avoid movements harmful.

On the other hand, the shock absorber (1) is designed for preferential mounting on uprights (7) intermediate blinds (6) since it is at those points where produce the maximum elongations in the vibratory movement of the Blinds. For cases where there are no intermediate amounts (7), the inventor designs an alternative solution that allows the immobilization of the shock absorber (1) on the glass (7.1) of the window by means of two suction cups (9), which favors the choice of the place of placement.

On the other hand the use is also conceived of a screw with a pin (10) at any of the points of turn. Figure 4 shows the case in which the palomilla is places at the upper pivot point, but the solution is applicable in  any other point. This allows the immobilization of the damping device (1) to prevent accidental movements.

As for the slat materials they can be wood, plastic, aluminum, or any other similar, of preferably square section.

The plates (6) can be metallic in iron, aluminum or similar or also of a hard plastic that has the enough consistency for the purpose pursued.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the 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, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications to the shape, size and / or Manufacturing materials; that is, the terms in which it has remained Exposed this preferred description of the invention, should be always taken with a broad and non-limiting nature.
