Abstract

This mixed slat (1) is formed by an aluminum profile (2) a piece of wood (4) and two intermediate pieces (3) of rubber placed between the aluminum profile and the piece of wood. The aluminum profile (2), is designed to control ventilation, regulate the exterior light from the maximum brightness to the dim light until the desired intimacy is achieved. The two intermediate pieces (3) serve as an elastic element that allows the aluminum profile to fit with the wooden profile and the second is to break the thermal bridge of the aluminum profile. The side of the piece of wood (4) seen from a room, completely covers the inside of the plank. Its outer side has two trapezoids that fit into the straight aluminum profile (2). The function of this piece is to serve as thermal and acoustic insulation of the blind.

Description

Mixed slat with thermoacoustic insulation.

Object of the invention

This invention relates to a new type of slat for window and door blinds, which combines the characteristics of aluminum with a natural raw material such as wood, for the control of air, light and outside temperature.

Background of the invention

There are currently several types on the market of slats for roller blinds of various materials such as, aluminum, wood, diverse and reflective fabrics, plastic etc. Y different styles like Majorcan, folding, extensible, sliding etc.

There is also another type of metal slats that they are used in Venetian blinds placed inside a window of double glass that forms a chamber. It is powered externally by a magnetic device Other type of aluminum slat Extruded widely used in the manufacture of blinds, It has its continuous contour section and hollow interior, filled with Polyurethane foam.

All these types of slats for blinds if well they fulfill their function of controlling the exterior light, they are only suitable for hot climates where the insulating function that the blind can have as a complement to general enclosure, without taking into account the thermal losses that they occur through windows whose coefficient of Heat transmission is usually relatively high compared to the of the walls.

In order to provide a technical solution Innovative to the problem posed, the author of this invention has developed a new type of mixed slat that is described to continuation.

Description of the invention

This invention consists of a slat for blinds Rollers composed of pieces of different materials. This formed by an aluminum profile that constitutes the outer part of the blind, a wooden profile that constitutes the piece inner and two intermediate rubber parts facilitate assembly between the aluminum profile and the wooden profile.

Each of the pieces of this lama has a different function, the semi-elliptical outer face of the profile of extruded aluminum, has a shape specifically designed with in order to control ventilation, regulate outside light from the maximum luminosity to the gloom to get the desired intimacy Guarantees effective sun protection in the summer months, reaching dimming levels until almost 100% Its slight curvature also allows to cancel the effects bothersome of the reflections and the incidence of the sun when it is in The horizon.

The inner face of said profile has a series of protruding arms arranged perpendicular to said profile, whose free ends have a circular section of diameter greater than the thickness of the arm wall mentioned. This circular section is arranged so eccentric so that considering two consecutive arms and faced, they constitute a kind of clamp whose function is that of fit the intermediate piece to prevent it from coming out.

The two intermediate pieces are the same and are formed by a trapezoidal section rubber profile whose contour exterior is very similar to the interior contour of the mirror image of the clamp described in the previous paragraph. This piece has two perfectly determined functions, the first is to serve as elastic element that allows to fit the aluminum profile with the wood profile being these two totally different materials and the second is to break the thermal bridge of the profile of aluminum.

The outer piece of wood covers the face Interior of the plan view from a room. Your section has a specific form; its outer side has two trapezoids that they serve as a fastener and that fit the profile of aluminum through the rubber intermediate piece. The side interior is smooth and concave for the most part with its end bottom straight.

The function of this piece is to serve as thermal and acoustic insulation of the blind.

Description of the drawings

To complement the description of this invention and in order to facilitate the understanding of its characteristics, a series of figures are accompanied in which with character Illustrative and not limiting, the following has been represented:

Figure 1 is a profile view of the slat mixed (1) with all its components assembled. It is observed at aluminum profile (2), intermediate parts (3) and the piece of wood (4).

Figure 2 is a view of the aluminum profile (2), which highlights the frame (2.1) of the slat with its face outer (2.6) convex and its inner face (2.7) concave, its end upper (2.2) with open hook shape, its lower end (2.3) also with hook shape but almost closed, the arms (2.4) perpendicular to the frame (2.1) each with its end eccentric circular (2.5). The two central arms (2.4) of the frame (2.1), are very close and form a hole between them (2.8).

Figure 3A is a profile view of the piece intermediate (3), which highlights the central bridge (3.1), the flexible wings (3.2) and grooves (3.3) that house the eccentric ends (2.5) of the aluminum profile (2).

Figure 3B is an enlargement of a part of Figure 3A, which highlights multiform recesses (3.4) of the intermediate piece (3), which by decreasing the section constitute the fold where said piece is flexed to fit Easily contour the remaining pieces and facilitate your coupling

Figure 5 is a profile view of part of a blind with its mixed slats (1), which highlights the piece of wood (4).

Preferred Embodiment of the Invention

Among the different possibilities of building this mixed slat, the preferred embodiment is described as continuation:

This mixed lama (1) is composed of four previously designed parts according to their specific function, Two of them are the same. The aluminum profile (2), has a face exterior (2.6) convex that allows to cancel the annoying effects of the reflections of the sun and its incidence when it is in the horizon. Top end (2.2) hook-shaped semi-open, it is assembled with the lower end (2.3) in the form of semi-closed hook when mounting the blind, said blind constituting a kind of articulated chain. The joint that form both hooks allows not only a lama join with another to form the blind, but also facilitate its rolling.

The arms (2.4) with their circular ends Eccentric (2.5), formed with the intermediate piece (3) and the appendix of lace (4.2) of the piece of wood (4), a tail-type joint of dove The two arms (2.4) that are located in the middle of the frame (2.1) form a hole (2.8) that allows to screw a side cover, so that the slat components remain in their position and do not shift.

The intermediate piece (3) of rubber, has sufficient elasticity to facilitate the fit of the two main rigid elements, the aluminum profile (2) and the piece wooden (4). As seen in Figure 3B, at the junction of their different parts, the intermediate piece (3) has a series of multiform recesses (3.4) that allow each other to adapt contours of all the components of the mixed slat (1).

The piece of wood (4), is the component that characterizes this invention and whose insulating properties both thermal as acoustic, are what define this mixed lama (1). In Figure 5, a section of a blind can be seen when it is in a closed position and particularly to the thermal barrier and acoustics that constitute the piece of wood (4).

Once nature is sufficiently described of this invention, as well as a preferred embodiment thereof, it only remains to add that, its form and execution of it, are susceptible of modifications, as long as they do not affect substantial form to the characteristics that are claimed to continuation.
