The invention relates to a profiled element. for use in furniture type closet, being able to the elements profiled assemble to form rolling shutters and guiding and moving the latter with their free lateral ends by guide rails fixed to the mentioned type furniture wardrobe.

For the company brochure "Aluminumrolladensystem" (roller blinds system of aluminum) from Schüco, for example, elements are known Profiles of this genre.

These profiled elements, manufactured in Aluminum in an extrusion process, can be joined to form roller blinds and be installed in furniture type closet both horizontally as vertically. Due to the inherent properties to the material used, these profiled elements and the blinds Rollers manufactured from them have a large Stability and resistance In addition, the characteristics of the metal used make the material provide an appearance, demanded by certain clients and designers, of being of great quality. He design in terms of shape and color of the different sheets is a Significant style medium for tall cabinet type furniture level.

These roller blind systems they have, in addition to the weight of the assembled roller blinds, the disadvantage of both its cost and the qualities of perceived slippage in daily operation during opening and closing of cabinets.

Through the use of aluminum, which conforms to an expensive extrusion process to obtain elements profiled, it is only possible to manufacture profiled elements individual, which greatly increases economic spending. Other disadvantage is the noise that occurs when moving blinds Rollers installed vertically or horizontally.

Since the guide rails fixed to the cabinets are preferably composed of a polymeric material and exposed to certain manufacturing tolerances, when moving a Rolling shutter produces a metallic noise, eventually strong, and high wear on the surface of the rails of guide, conditioned by the heterogeneous metal pairing with the polymeric material.

This disadvantage is attempted to remedy using the free side ends of the profiled elements as well calls, terminal corners in which some are integrated rolling rollers

This causes the cost to increase, since, in addition to mount the profiled elements to form the blind Rollable, at the free ends of each profiled element have to mount the corresponding terminal corners with the rolling rollers Another additional expense is produced by the manufacture, storage and logistics of rollers rolling and the end corners as preformed parts, for which have to acquire the corresponding tools.

In EP 0558390, in which describes a profiled element of this genre for a blind Roller of polymeric material, alternatives to this are presented solution.

This profiled element has a section transverse with essentially trapezoid shape and is manufactured in a hard polymeric material. On at least one side of this profiled element a band of a material has been coextruded flexible whose width corresponds essentially to the difference between the lengths of the long and narrow sides of the element profiled The band joins a ring of hard material to one of the sides of the profiled element. The profiled element presents, in the opposite side of the band, a housing that is provided with a opening facing outward and having a similar size to the wall thickness of the profiled element. The section cross section of this housing and the cross section of the ring they have essentially identical shapes and dimensions, with certain play between them so that the ring can slide freely in the accommodation.

In comparison with roller blinds made of aluminum, assembled from these elements Profiles have a much lower weight and a very low price. The sliding qualities of these roller blinds in the guide rails, which are also made of a material polymeric, can be described as excellent.

The union of the different profiled elements by the ring, which is attached to a first profiled element by means of a flexible / elastic band that can be assembled to form roller blinds by inserting one or more elements additional profiles, especially during opening and the closing of the roller shutters and in the return by means of the guide rails in the endless guide screws, advantages as for the bending radius that guarantee a better use of cabinet volume.

However, with these roller blinds polymeric materials it is not possible to perform the characteristics or the appearance of a high quality material, achieved with the aluminum.

Printing or coating procedures already known in the current state of the art allow to perform imitations of a high quality material on the surface of the profiled elements, but these do not reach the characteristics nor the appearance of the profiled elements, for example of aluminum.

This is where the invention comes into play, which The objective has been to show easy profiled elements to assemble and economical to manufacture, that present the advantages of profiled elements made of metallic materials, such as The great stability and strength, the appearance of a high material quality in terms of decoration, and surfaces with Advantages of profiled elements made of materials Polymers, such as low weight and reduced price, qualities for a very quiet gliding and with little friction and flexible flange joints that are easy to assemble and that Make the most of the closet volume.

According to the invention, the objective is achieved thanks to which the profiled element is constructed from a portion lower, made of polymeric material, and an upper portion which is attached to the lower portion and constituted of material metal.

This combination of the two materials allows surprisingly optimally and economically combine the advantages of roller blind systems made of materials metal with the advantages of materials manufactured polymeric

The weight per unit area of the roller blinds assembled from the elements profiled according to the invention exceeds only insignificantly the one of the systems of roller blinds of materials polymeric

The profiled element according to the invention can manufactured for example by the extrusion process, coextruding the lower portion with the flexible material band and the annular element and setting in an operation subsequent to the lower portion the upper portion composed of material metal.

From DE 2622905 A a known profiled element for use in windows, the element being able to profiling assemble to form rolling shutters and guiding and moving the latter with their free lateral ends by a fixed guide rails. The profiled element has a lower portion, constituted of a polymeric material, and a upper portion that is attached to the lower portion and constituted of metallic material. The profiled element also has a upper section in the form of a hook, which also has a lower portion of polymeric material and an upper portion that is attached to this lower portion and constituted of material metal. The lower portion, called the plastic element, is configured as a hollow profile and presents, on its opposite side to the hook-shaped section, a tongue section that is configured as a hook-shaped limb. Shaped end Hook serves to hold other profiled elements subsequent, which can be housed in this through the section in the form of a hook.

From document DE 8102096 another one is known profiled element for use in rolling doors, being able to the profiled element assembled to form roller blinds and guiding and moving the latter with its ends free sides by fixed guide rails. The element Profiling is constructed from a lower portion, constituted of polymeric material, and an upper portion that is attached to the lower portion and constituted of metallic material. The lower portion composed of plastic and configured as a profile hollow should be fixed to the upper portion in drag form. The profiled element consists of a metallic upper portion with relatively thin walls, and shaped by rollers, and of  a hollow profile fixed thereto in shape drag. The side upper and longer of the upper portion is transformed into a, so called, marginal roller rolled and almost closed. The side lower is curved inward at an acute angle forming a straight transition zone, following this transition zone a lower marginal roller whose inner diameter is sparsely greater than the outer diameter of the marginal roller in each case higher. Fitting longitudinally on each other, the sheets profiled with its upper marginal roller in the marginal roller lower in each communicating case you get a blind roller.

The invention further teaches that the portion Lower coextruded polymeric material is attached to the portion upper metal material forming a single piece, so that the assembled roller blind is distinguished, in addition to a excellent stability and resistance, motivated by the union in a piece between the two parts of the profiled element, also by the High quality metallic material appearance.

Another possibility to manufacture the profile according to the invention consists in joining the upper portion of material metallic to the lower portion of polymeric material by glued.

In another advantageous embodiment of the profiled element according to the invention, the upper portion is attached to the lower portion detachable.

In this way it is possible to make available a lower portion as standard and adapt the upper portion individually to the client's wishes regarding color and design. This reduces on the one hand the storage costs of the portion lower and moreover increases flexibility with respect to client.

Through these manufacturing procedures the profiled element according to the invention it is possible to use a process continuous production such as extrusion to achieve a cost reduction in relation to the manufacture of the elements profiled in metallic materials, which allows a production Economic and lucrative.

Another advantage of the procedure according to the invention is that when opening and closing the blinds roller assembled from profiled elements according to the invention, no loud metallic noises are produced, since these they are absorbed by the lower portion of polymeric material. In addition the terminal corners and the rollers of rolling, necessary in the current state of the art, that were to be mounted on the free side ends of the profiled elements to achieve sound insulation.

By using the, itself already known, union of the profiled elements with each other by means of a ring, which is attached to the profiled element by a band flexible / elastic, it is possible to manufacture the guide rails and Endless guide screws needed in cabinets in one material polymeric equal to or similar to that of the lower portion of the element profiled and thus achieve the roller blinds assembled to from the profiled elements they move with little noise and little friction In this way it is also possible to size the Endless guide screws so that the volume of the cabinets It can be optimized by the customer.

With roller blinds susceptible to be assembled from the profiled element according to the invention bending radii much smaller than with the Made of metallic materials.

Another advantage of the profiled element according to the invention is that the upper portion of metallic material covers the lower portion of polymeric material of the element profiled only partially.

In this way it is possible to achieve the same effect than in a roller blind of metallic material, but using much less material. This reduces the cost of profiled element according to the invention and economizes on the other hand the resources for the manufacture of, for example, aluminum.

Through the fixed connection of the lower portion polymeric to the metal upper portion it is also possible to achieve the same excellent stability and resistance properties of roller blinds composed of profiled elements metallic, without also transferring the worst qualities of slip and noise generation.

By using a lower portion of polymeric material used for different upper portions of metallic materials it is possible to satisfy quickly and economically changing customer requirements in terms of Decoration, color and design.
