Description

Double wall door with element decorative.

Object of the invention

The present invention, as expressed in the statement of this specification refers to a door double wall with decorative element whose essential purpose it consists of providing the referred door with some elements decorative finishes and durability far superior to that present the current decorative elements of this type of doors, so that the resistance of the decorative elements provided by the present invention has a resistance comparable to that of the structure of the corresponding door.

Background of the invention

It is currently remarkably extended the use of doors of the so-called double sheet or double wall, provided with a front plate, a back plate and a padding injected with polyurethane, used in applications beyond the traditional ones like landings in stairs, industries, firewalls or others; so that now being habitual to use these double wall doors in main entrances of houses and local, it is convenient to provide them with some decorative element that makes them more colorful than the doors with smooth plates used in those traditional applications. To do this, the Current state of the art provides profiles or moldings that stick with adhesive materials on smooth faces external of the door plates. These decorative profiles that stick to the doors have problems related to their finish and more especially its poor durability due to the ease with which they detach from the surfaces on which they find those profiles or moldings attached.

Description of the invention

To achieve the objectives and avoid drawbacks indicated in previous sections, the invention It consists of a double wall door with decorative element, where the door has a front plate and a rear plate  among which a filler of injected is injected polyurethane.

Novelly, according to the invention, at least one of these plates has one or more holes or punches by the that respective pieces or moldings are visible; presenting each one of these pieces a highlight or visible area and wings of retention on the internal surface of the corresponding sheet; thus establishing the referred decorative element.

According to various embodiments of the invention, the aforementioned wings are retained on the aforementioned surface internal by the corresponding injection process of polyurethane, by other means of mechanical fixation, by means of chemical fixation, or by any combination of the above options.

According to the preferred embodiment of the invention,  covering the wings of the piece and at least part of the referred internal surface of the sheet, a protective sheet is arranged, preferably by adhesive, which prevents leaks of the polyurethane padding to the holes or dies of the lock.

In the preferred embodiment of the invention, the mentioned pieces of moldings are made of steel stainless, and can also be made with other materials.

With the structure described, the door double wall with decorative element of the invention presents relative advantages to that it allows to provide decorations of very various configurations, and with a very strong resistance and durability superior to those of the existing decorative elements in the state of the art for this type of doors.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Brief description of the figures

Figure 1.- Represents a perspective view. of a double wall door with decorative element made according to the present invention.

Figure 2.- Represents a partial view of the door referred to in the previous figure 1, showing the section indicated in said figure 1.

Description of an embodiment of the invention

Following is a description of a example of the invention with reference to numbering Adopted in the figures.

Thus, the double wall door with element decorative of this example of the invention, includes a sheet anterior 1, a posterior sheet 7 and an injected filler of polyurethane 5 disposed between those plates 1 and 7, as can can be seen in figure 2.

The front plate 1 has several holes or dies 2 for which some pieces or moldings are visible 8, as can be seen in figure 2.

Each piece 8 includes a highlight or visible area 3 and wings 4 that facilitate retention on the inner surface of sheet 1; establishing with it the decorative element of the door on the front of it, as seen in Figure 1. However, this element configuration decorative that has been described for the front face of the door could be presented in other examples on the back side or in both, by virtue of the analogy between plates 1 and 7.

In the present example of the invention the wings 4 of the pieces 8 are retained on the inner surface of the sheet 1 by the polyurethane 5 injection process itself inside the door. However, in other examples they could fix those wings 4 on the corresponding internal surface by other means of mechanical fixation, by means of chemical fixation or by any combination of the options described.

In order to avoid possible leaks of the polyurethane 5 towards the dies 2, in the present example they use protective sheets 6 that cover wings 4 and part of the internal surface of the front plate 1, as shown by the figure 2; fixing these protective sheets 6 by adhesive. However, in other embodiments, these could be dispensed with. sheets 6 or protection against leaks through of other means.

In the present example the pieces or moldings 8 They are made with stainless steel, which determines a large strength and an excellent aesthetic finish, and can be used not Despite other materials for other examples of the invention.
