Description of Related Art The refrigerators are usually divided into at least two compartments, a first refrigeration compartment and a second freezing compartment; it is normal for both compartments to have a different temperature. Usually, domestic refrigerators have both trays or shelves as drawers to accommodate products that are to be stored and stored. These drawers are designed to be slidably housed inside the compartments, manufactured in different sizes, shapes and materials. It is also common that the shelves or trays are designed to be fixed within the compartments, manufactured in standard sizes and shapes that run the width and bottom of the compartments. The materials of such shelves or trays may vary.

Each compartment is delimited by an internal wall. It is common for the inner wall of the refrigerator to be known in the middle as a "liner". It is also common for the rear part of the liner to be substantially vertical, and for the liner side portions to also be substantially vertical. It is common that in each of the lateral parts of the liner there are a plurality of co-linear projections on which the drawers are placed. It is also common for the drawers to have slides that can be mounted on said projections, where the drawers can slide on said projections in view of the slides.

Examples of the above exist in art. Such sliding systems can be seen in the publications: CN 1940441 A, KR 20080066450 A, US 4,441,771 A, US 7,963,408 B2, US 4,936,641 A, CN 2531336 UY, US 7,140,703 Bl, US 2,676,863 A, US 6,015,053 A, US 2011 / 018,414 Al, US 3,716,282 A, CN 102052817 A, US 4,922,811 A, CN 201152663 UY, KR 20060101038 'A and CN 201897360 U.

The front end of the bottom wall is substantially straight and horizontal. At a front point of the lower wall, an inclination with downward direction is provided according to the drawer in such a way that the lower wall is far away from the upper wall. The remainder of the front part and the intermediate part of said bottom wall is substantially straight and horizontal. At a rear point, between the intermediate and the rear end of said lower wall, the corrugation in the lower wall is provided. The crook comprises a first wall substantially vertical to the lower wall, with a downward direction conforming to the drawer; a second curved wall of approximately 180 ° towards the rear of the lower wall and towards the upper part of the drawer; and a third wall facing away from the first wall and substantially perpendicular to the bottom wall. The remainder of the rear part, specifically between said bending of the lower wall and the rear end, is substantially straight and horizontal, until it joins again with the curved rear wall.

The drawers 2 are usually constituted by a base 4, a front wall 6, a rear wall 8 and at least two side walls 10, 10 '. It is common for side walls 10, 10 'to be fitted with slides 40, as can be seen in figures 1 and 2. In this case, the slides 40 are in the upper part of the side walls 10, 10' of the drawer , however, they can be placed anywhere on the side walls. It is common for the slides 40 to run from the front to the rear of the side walls 10, 10 '. It is also common for the slides 40 to be co-linear with each other, that is, they are at the same height in each of the side walls 10, 10 '. On each side wall of the refrigerator liner, a series of co-linear projections 14 are provided on which the slides 40 of a drawer 2 are placed. The slides 40 of the drawer 2 slide on said projections 14.

In the case of the present invention, both the projections 14 of the liner 12 and the slide 40 have a specific design. The following description makes reference to figures 1 to 9A in an indistinct manner.

The front end 28 of the lower wall 26 is substantially straight and horizontal according to the liner 12. At a front point of said lower wall 26, close to the front end 28, a perpendicular part 30 is presented to said front end 28, with a direction down. Said perpendicular part 30 has a length similar to or less than a bend 68 in the lower wall of the slide 40. The length of said perpendicular part 30 is important to give a certain inclination to the slide 40, and consequently to the drawer 2, during its initial extraction steps. At a front point of said lower wall 26, at the opposite end of the perpendicular part 30 where the front end 22 of the lower wall is located, specifically where the apex 34 is formed, said lower wall becomes substantially straight and horizontally in line with the liner 12 towards the rear of the liner 12. In a rear part, close to the rear end 36 of the lower wall 26, an inclination 32 with a downward direction is presented, so that if the upper wall 16 was completely straight, the upper wall 16 and the lower wall 26 would distend.

It is preferred that the rear end 36, the part substantially straight and rear horizontal of the lower wall 26, be between 18% and 27% of the total length of said lower wall, especially it is preferred that said length of the rear end be between 21% and 24% of the length total of the bottom wall. On the other hand, it is preferred that the rear end 22, the substantially straight and horizontal rear portion of the top wall 16, be between 4% to 8% of the total length of said top wall, especially it is preferred that said end length back is between 5% to 7% of the total length of the top wall. It is also preferred that the vertex 34 be a curved vertex. The curve at apex 34 will allow the lower sway 68 to engage said apex. It is preferred that the length of the front end 28 of the bottom wall 26 be between 12% and 18% of the total length of said bottom wall, especially it is preferred that said length of the front end be between 14% and 16% of the length. total length of the lower wall.

As mentioned above, the slides 40 of the drawers 2 also have a specific design. The slides 40 comprise an upper wall 42, a lower wall 60, a rear wall 56 and a front wall 78. At its front end 44, the upper wall 42 is substantially straight and smooth according to the liner 12. In a front part, between the front end 44 and the intermediate part 52, the upper wall 42 has a first crook 46. The first crook 46 has a first wall 48 substantially perpendicular to the front end 44 of the upper wall 42, the first wall 48 has a direction towards above according to the drawer 2 and a second wall 50 having an inclination with downward direction It is preferred that the apex of the upper face of the front end 44 of the upper wall and the external face of the first wall 48 of the. first crook 46 has an obtuse angle. Especially it is preferred that this obtuse angle of the apex between the front end 44 and. the first wall 48 is in a range of between 91 ° to 110 °, especially between 95 ° to 105 °.

The remaining front part, the intermediate part 52 and part of the part rear of upper wall 42 is substantially straight and horizontal again; this remaining part of the front, intermediate 52 and rear part of the upper wall 42 has substantially the same height as the front end 44 of the upper wall 42, whereby said front end 44 and the intermediate part 52 are co-linear. At the rear end of the upper wall 42 a second crook 54 of the upper wall is provided. The second crook 54 has a first wall 56 with an inclination with an upward direction according to the drawer 2 and a second wall 58 having an inclination with a downward direction according to the drawer. The apex between the first wall 56 and the second wall 58 is preferably curved.

Especially, it is preferred that said vertex angle be between 140 ° and 175 °. The second wall 58 of the second crook 54 joins, at its end opposite the apex with the first wall 56, the rear wall 80, which continues the corrugation of the second wall 58, such that the rear wall 80 is a curve of approximately 180 ° to join with the rear end of the lower wall 60. The front end 62 of the lower wall 60 is substantially straight and horizontal and substantially parallel to the front end 44 of the upper wall 42. At a frontal point of the lower wall 60, an inclination 64 is provided with downward direction according to the drawer 2 in such a way that the lower wall 60 ceases to be parallel with the upper wall 42 and in such a way that the lower wall 60 is distant from the upper wall. 42. The remainder of the front part and the intermediate part 66 of said lower wall 60 is substantially straight and horizontal. At a rear point, between the intermediate part 66 and the rear end 76 of said lower wall 60, the buck 68 is provided in the lower wall. The lower bend 68 comprises a first wall 70 substantially vertical to the lower wall 60, with downward direction according to the drawer 2; the apex between the intermediate part 66 and the first wall 70 may be a right angle or an obtuse angle, wherein the range of said obtuse angle is close to the right angle, i.e. between approximately 90.1 ° to 99 °; a second curved wall 72 of approximately 180 ° towards the rear part of the lower wall 60 and towards the upper part of the drawer 2; and a third wall 74 facing away from the first wall 70 and substantially perpendicular to the bottom wall 60, wherein said third wall 74 has the same angle at the apex with the lower wall 60 as the first wall 70 and the lower wall 60. The remainder of the rear part, specifically between said curvature of the lower wall and the rear end 76 , is substantially straight and horizontal, until it joins again with the curved rear wall 80. It is preferred that the front wall 78 also be a curved wall of approximately 180 ° connecting the front end 44 of the upper wall 42 with the front end 62 of the lower wall 60, however, this front wall 78 can take on any shape.

In a storage position, the first crook 46 of the upper wall 42 of the slide 40 is close to the front end of the upper wall 16 of the projection 14; the front end 62 of the lower wall 60 of the slide 40 rests on the front end 28 of the lower wall 26 of the projection 14; the inclination 64 of the lower wall 60 of the slide 40 is not in contact with the lower wall 26 of the projection 14 of the liner 12 in view of the height difference created between the front end 28 of the lower wall 26 and the rest of the lower wall 26. on the part of the perpendicular part 30 in the lower wall of the liner; the second upper crook 54 is close to the rear end 22 of the upper wall 16 of the projection 14; the rear wall 80 of the slide 40 is in contact with the rear wall 24 of the projection 14 of the liner 12; and the curvature 68 of the lower wall is in contact with the rear end 76 of the lower wall 60.

In a first extraction position, the first crook 46 of the upper wall 42 of the slide 40 is offset according to the front end of the upper wall 16 of the projection 14; the front wall 78 of the slide 40 this outlet according to the front end 28 of the lower wall 26 of the projection 14; the inclination 64 of the lower wall 60 is in contact with the upper end of the perpendicular part 30 in the lower wall 26 of the projections 14 of the liner 12, and the lower bending 68 of the lower wall 60 of the slide 40 is in contact with the rear inclination 32 of the lower wall 26 of the projection 14 of the liner 12, whereby the slide 40, and consequently the drawer 2 remains without inclination during this first extraction position. The second upper crook 54 is close to the inclination 20 of the upper wall 16 of the projection 14 of the liner 12.

In a second extraction position, the front part of the slide 40, including the front wall 78 and the front ends 44,62, is located in accordance with the projection 14. A front / intermediate part 66 of the bottom wall 60 of the slide 40 rests on the front end 28 of the lower wall 26 of the projection 14 and the curvature 68 of the lower wall 60 of the slide 40 is in contact with the intermediate part of the lower wall 26 of the projection 14, specifically between the perpendicular part 30 and the inclination 26 of the lower wall 26 of the projection 14. At this point there may be an inclination of the slide 40, and consequently of the drawer 2, forward, so that the front part 82 of the drawer 2 is in a lower position than the rear part 84 of the drawer 2. This depends on the height of the corrugation 68 of the lower wall 60 of the slide 40 and of the height of the perpendicular part 30 of the lower wall 26 of the projection 14. If the height of the corrugation 68 is greater than the height of the perpendicular part 30, then there is an inclination as described above; if the heights are equal, then there should not be an inclination. It is not desirable that the height of the perpendicular part 30 be greater than the height of the corrugation 68, since the drawer 2 would have a backward inclination and the force of gravity towards the bottom of the refrigerator cavity would be constant during the process of extraction, making it difficult to extract the drawer 2.

In a third extraction position, the front part of the slide 40 is located according to the projection 14, the intermediate part 66 of the lower wall 60 of the slide 40 rests on the front end 28 of the lower wall 26 of the projection 14 and the curvature of the lower wall 68 is in contact with the intermediate part of the lower wall 26 of the projection 14. Likewise, at this point there may be an inclination of the slide and of the drawer, which will depend on the height of the the curvature 68 of the lower wall 26 of the slide 40 and of the height of the perpendicular part 30 of the lower wall 26 of the projection 14 · In a fourth extraction position, the front part and at least part of the intermediate part, including the front wall 78, the front ends 44,62, and part of the intermediate parts 52,66 of the slide 40, is located in compliance with to the projection 14. The intermediate part 66 of the lower wall 60 of the slide 40 rests on the front end 28 of the front wall 26 of the projection 14. The curvature 68 of the lower wall 60 of the slide 40 is in contact with the intermediate part of the lower wall 26 of the projection 14. As in the second and third extraction position, there can now be an inclination of the slide 40 and of the drawer 2.

In a fifth extraction position, the front part and at least half of the intermediate part of the slide 40 are outlets according to the projection 14. An intermediate part 66 of the lower wall 60 near the rear part of the slide 40 rests on the front end 28 of the lower wall 26 of the projection 14. The curvature 68 of the lower wall 60 has ceased to be in contact with the lower wall 26 of the projection 14, and the second upper bending 54 has contact with an intermediate part. 18 near the front part of the upper wall 16 of the projection 14. At this point there is an inclination of the slide 40 and of the drawer 2, where the inclination is controlled by the support between the intermediate part 66 of the lower wall 60 of the slide 40 over the front end 28 of the lower wall 26 of the projection 14 and by the contact between the second upper crook 54 of the slide 40 with the intermediate part 18 of the upper wall 16 of the projection 14.

In a sixth extraction position, the front part and the intermediate part of the slide 40, including the front wall 78, the front ends 44,62, and part of the intermediate parts 52,66 of the slide 40, are found in accordance with to the projection 14.
