The present invention refers to an innovative constructive arrangement introduced in profiles for sliding of drawers in general, which comprises a parallelepiped body that is excavated and with longitudinal saliencies.

This invention refers a profiles for sliding of drawers with double longitudinal <BR> <BR> projections, i. e. , for supporting the drawer directly lying on it and the lower drawer.

Wooden profiles are known and widely used, actuating as a track and supporting, in the bottom, and guiding laterally the drawers. However, this type of track causes a great deal of friction with the drawer, therefore making the opening of the furniture difficult and heavy. It is important to stress that two wooden pieces are generally used, one to support the bottom and the other to guide the drawer laterally. Thus, there are four surfaces of contact : two in the sides and two in the bottom. The problem related to the friction was resolved with the substitution of the wooden profiles for a metal track system, which are attached to the drawer, and rollers attached to the furniture in which the drawer slides. However, this new system requires a high number of components and a complex assembly process, which increases the price of the product and reduces the merit of the system.

Those known profiles do not guide the upper edge of the drawer, leaving a gap that may allow the drawer to move vertically. That movement is undesirable, as it may cause the drawer to run off the rails, requiring effort from the user to reposition it.

Additionally, it is desirable that the piece of furniture features a post system to prevent total removal of the drawer, as it may fall down unintentionally, with risks of injuring the user and damaging the piece of furniture.

It is also desirable that the piece of furniture features sealing systems for the drawer compartment, in order to prevents any object therein contained, in case of falling, from mixing with the ones in the lower drawer.

Such a piece of furniture, with all those devices, may become complex and expensive to build.

The object of the present invention is a drawer profile that

efficiently resolves the problems found in the state of the art. This will be possible through a profile with a cut in one of the upper vertices, forming a transversal section substantially in"L". The faces of cut of the profile comprise continuous saliencies that support the bottom and the sides of the drawer. Thus, it drastically reduces the friction between the drawer and the profiles, which shall have their contact limited to the saliencies.

Optionally, the profile may be executed in two individual pieces, that may be whether united or not upon the assembly of the furniture, one to support the bottom, and the other to support the sides of the drawer.

Additionally, the profile also comprises a lower surface, provided with a continuous projection, which supports the upper edge of the lower drawer, preventing it from moving vertically. The proposed profile also features: a longitudinal groove for fitting a bottom plate of the drawer compartment, a frontal cutout, which allows sliding for adjusting the profile positioning in a crossbar of the piece of furniture, and an orifice to fit a limiting post for the drawer opening movement, which prevents the drawer from failing.

The object of this invention results in the following functional improvements in relation to the other drawer profiles known: - reduction of friction, ensuring a smooth opening of the drawer, without closing or requiring strength by the user; - the opening and closing is silent ; -simple assembly, being attached by clamps, nails, screws, or similar ; - has a longitudinal projection also on the lower face of the profile, which guides the lower drawer superiorly; - has a longitudinal groove that allows fitting the drawer compartment bottom; - is provided with a frontal cutout that facilitates the lateral adjustment of the profile positioning, resulting in smooth sliding of the drawer; - allows the post to fit into the profile, intended to limit the drawer opening.

The new construction arrangement introduced to drawer profiles, object of this invention, may be understood more clearly through the following detailed description, based on the drawings attached hereto, as follows : Figure 1-perspective of the drawer profile ;

Figure 2-frontal view of the drawer profile; Figure 3-perspective of the profile with the drawer installed ; Figure 4-frontal view of a constructive option of the profile.

Figure 5-perspective of a second option of the profile ; Figure 6-frontal view of the second option of the profile ; Figure 7-side view of the second option of the profile ; Figure 8-frontal view of an application of the second option of profile.

Figures 1 to 3 illustrate the new construction arrangement introduced to drawer profiles, comprising a body (1) substantially parallelepiped and continuous, with a cut (2) in one of its upper vertices, forming a transversal section substantially in"L". The faces of the profile's cut comprise continuous saliencies (3) that support the bottom and sides of the drawer (G), where it slides entering in contact with the saliencies (3) only, with reduced friction.

Figure 4 demonstrates a constructive option of profile that comprises two individual pieces (1'and 1"), that may be whether united or not during the assembly of the furniture. Each one of these pieces (1'and 1") counts on a salience (3'and 3") to support the bottom and sides of the drawer.

Figures 5 to 7 illustrate a second constructive option of the profile for drawers, that also comprises a substantially parallelepiped and continuous body (10), with a cut (20) on one of its upper vertices, forming a substantially"L"shaped transversal section, on whose faces continuous saliencies (30) are positioned, which allow inferior and lateral sliding of the drawer, providing reduced friction. But the profile body (10) comprises also a lower surface, also provided with a continuous salience (40), which supports the upper edge of the lower drawer. The profile (10) also features a longitudinal groove (50) for fitting a bottom plate, which defines the tight compartment for the drawer, a frontal cut (60), which allows lateral sliding, to adjust the profile positioning in a crossbar of the piece of furniture, and an orifice (70), for fitting a limiting post for the drawer opening movement, not illustrated.

Figure 8 illustrates the profile (10) applied to the piece of furniture, which supports the lower edge of an upper drawer (G), by means of continuous saliencies (30) of the cut (20), and the upper edge of a lower drawer (G'), by means of a continuous saliencies (40). On that figure, it is possible to see the bottom plate (F) of the drawer (G) compartment, fitted into the longitudinal groove (50).
