Referring to this in more detail with reference to FIG. 5, the elastic pivot 700 includes a pivot lever 720, a lever case 760 and an elastic member 740.

The pivoting lever 720 is in contact with both sides of the drawer 500 by the rotation to press the drawer 500, is formed in a substantially fan-shaped or triangular shape. The rotation lever 720 may be any shape as long as it can press the drawer 500 by rotation. However, in the preferred embodiment, the rotation lever 720 is formed in a fan shape for convenience of description.

The rotating lever 720 formed in a fan shape is formed in a plate shape having a predetermined thickness, and the rotating shaft 722 protruding upward and downward perpendicular to the surface of the rotating lever 720 at one end corresponding to the center of the fan shape. ) Is formed. The rotation shaft 722 is to be the rotation center of the rotation lever 720, and is rotatably mounted on one side of the lever case 760 to be described below.

The pivot lever 720 is formed to form an acute angle (less than 90 °) when the rotation shaft 722 is centered, and one side of both sides of the fan is exposed to the outside of the rail groove 620, and the other The side surface is mounted to be inserted into the inside of the lever case 760. In addition, the portion corresponding to the fan-shaped arc in the pivoting lever 720 is adjusted according to the rotation of the pivoting lever 720 is adjusted.

The pivot lever 720 is accommodated in the lever case 760. The lever case 760 accommodates the pivot lever 720, and is formed as one side of the lever lever 760. The lever case 760 is generally inserted into the rail groove 620 of the guide rail 600.

The lever case 760 is formed of a conventional case body 762 which completely receives the pivoting lever 720 by the rotation of the pivoting lever 720 and an opening 766 formed at one side of the case body 762. And an extension 764 extending vertically along the outer perimeter.

The case body 762 is usually formed to be somewhat thicker than the thickness of the pivoting lever 720, and the pivoting lever 720 is moved in or out through the opening 766 formed to be opened on one side.

The rotating shaft 722 of the pivoting lever 720 is rotatably coupled to one side end (shear front end in FIG. 5) inside the opening 766 of the case body 762. Accordingly, the pivoting lever 720 comes out from the opening 766 when rotated counterclockwise and enters the inside of the opening 766 when rotated clockwise.

The extension part 764 formed at the outer end of the opening 766 is in contact with the inner surface of the rail groove 620 when the lever case 760 is mounted, thereby assisting the mounting of the lever case 760. .

Meanwhile, an elastic member 740 is mounted inside the lever case 760. The elastic member 740 is to provide an elastic force so that the rotation lever 720 rotates in a counterclockwise direction, it is preferable that a torsion spring that is generally used is employed.

The elastic member 740, that is, the wound portion of the torsion spring is mounted in the same direction as the rotation shaft 722 of the pivoting lever 720, and an extended end of the elastic member 740 is rotated. The other end of the elastic member 740 which is in contact with the side surface of the lever 720 is supported inside the lever case 760.

Therefore, when the pivoting lever 720 rotates in the clockwise direction, the elastic member 740 is compressed to provide an elastic force in the counterclockwise direction to the pivoting lever 720. 720 protrudes outward from the rail groove 620 to be in contact with the side surface of the drawer 500.

As described above, the pivoting lever 720 is rotated by the elastic member 740 in the outward direction of the rail groove 620, and the side of the drawer 500 by the pivoting of the pivoting lever 720. In contact with the drawer 500 it is possible to mount a stable.

The elastic pivot 700 may be provided in plurality in the rail groove 620 of the guide rail 600, preferably as shown in Figure 5 the inner surface of the rail groove 620 (right side in Figure 5 The first half and the second half may be formed.

On the other hand, the elastic rotating body may omit the configuration of the lever case, in this case, the pivoting lever is mounted so as to be able to rotate inside the rail groove of the guide rail, enter or by rotating to the inside and outside of the rail groove It may be configured to protrude. Of course, at this time, the elastic member should also be provided inside the rail groove.

Hereinafter, the operation of the refrigerator drawer mounting structure according to the present invention having the configuration as described above will be described with reference to the drawings.

6A and 6B are longitudinal cross-sectional views schematically showing a state in which a drawer of the preferred embodiment of the refrigerator drawer mounting structure according to the present invention is mounted, and FIG. 7 is a drawer of the preferred embodiment of the refrigerator drawer mounting structure according to the present invention. A cross-sectional view schematically showing the state.

As shown in these drawings, the guide rail 600 is mounted on the left and right inner walls on which the drawer 500 is mounted inside the refrigerating chamber 300.

The guide rail 600 is fixedly coupled to the inner case 140 by a screw, and the heat insulating material 160 is foam-filled inside the inner case 140 so that the inner case 140 is somewhat in shape. Deformation of the dimension may occur.

After the mounting of the guide rail 600 is completed, the elastic pivot 700 is mounted on the guide rail 600. That is, the inner side of the rail groove 620 of the guide rail 600 (the right side in FIG. 6A) of the revolving body 700 including the pivoting lever 720, the elastic member 740, and the lever case 760. Insert it into the Of course, the guide rail 600 may be coupled to the inner case 140 while the elastic pivot 700 is mounted.

Next, the drawer 500 is mounted on the guide rail 600. Before the drawer is mounted, no external force is applied to the pivot lever 720 of the guide rail 600, so that the pivot lever 720 is moved by the elastic force of the elastic member 740. The state is protruded as much as possible, and therefore, the state protrudes from the inside of the rail groove 620 to the outside (left side in FIG. 6).

In this state, the drawer 500 is mounted on the guide rail 600, and the bent portion 520 of the drawer 500 slides to be drawn along the rail groove 620 of the guide rail 600. Push it in. As the drawer 500 is drawn, the drawer 500 is moved backward so as to be in contact with the pivot lever 720.

On the other hand, since the pivoting center 720 is located at the front of the pivoting center, a portion protruding outward of the rail groove 620 becomes larger toward the rear (right in FIG. 7), and the drawer (see above) Inclined toward 500).

Therefore, when the drawer 500 is pulled in, the side of the drawer 500 can be smoothly in contact with the pivot lever 720, and the side of the drawer 500 is pressed by the pivot lever 720 counterclockwise. It will rotate in the direction (see FIG. 7). That is, when the drawer 500 is drawn in, it is not disturbed by the pivoting lever 720.

In addition, when the drawer 500 is pulled out and removed from the guide rail 600, the force for pressing the pivot lever 720 is removed, and the pivot lever is rotated clockwise by the elastic member. And rotates so as to protrude from the inside of the rail groove 620 to the outside.

On the other hand, in the foam filling of the heat insulating material 160 during the molding process of the refrigerator main body 100, when the dimensional deformation of the inner case 140 occurs, the action of the elastic rotor 700 of the drawer 500 The position is compensated.

Looking at this in more detail, when the guide rail 600 is located on the inner side (left in Figure 6a) by the deformation of the inner case 140 as shown in Figure 6a, the drawer 500 The seating lever 720 of the elastic rotating body 700 is further pressed by the drawer 500 during the mounting of a relatively large portion into the rail groove 620.

That is, even when the guide rail 600 is located somewhat inside, the pivoting lever 720 which contacts the side surface of the drawer 500 protrudes less, so that the drawer 500 is not mounted properly by pressing the drawer 500. This does not occur and normal mounting is possible.

And, as shown in Figure 6b, when the guide rail 600 is located on the outer side (right in Figure 6b) than the original position by the deformation of the inner case 140, when the drawer 500 is seated The pivoting lever 720 of the elastic pivot 700 is less pressed by the drawer 500 so that a relatively large portion protrudes outward of the rail groove 620.

At this time, the elastic member 740 that provides the elastic force to the pivoting lever 720 has a difference in the degree of compression as a less compressed state compared to the state of Figure 6a.

As such, even when the guide rail 600 is located somewhat outside, the drawer 500 may be stably mounted without being removed by flow due to the rotation of the pivoting lever 720.

In addition, the elastic member 740 of the pivoting lever 720 may not only cause dimensional defects due to the molding of the refrigerator main body 100 but also when the drawer 500 swings while the refrigerator main body 100 is tilted or in use. By actively adjusting the degree of protrusion is prevented removal of the drawer (500).

On the other hand, the elastic pivot 700 is provided not only on the left and right sides of the drawer 500, but also provided on the rail groove 620 of the guide rail 600 on one side of the inner case 140 of the The drawer 500 can be mounted stably by compensating the position of each other even in various dimensional deformation.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

For example, in the exemplary embodiment of the present invention, for example, the drawer 500 is mounted on the guide rail 600 to be in contact with the elastic pivot 700, but the present invention is not limited to the drawer 500. It may also be applied to the shelf 400 or the basket 340 of the structure withdrawable / retractable without.

In addition, although the embodiment of the present invention has been described with the drawer 500 provided in the refrigerating chamber 300 as an example, it will be apparent that the present invention is applicable to the freezing chamber 200 as well as the refrigerating chamber 300.

In the refrigerator drawer mounting structure according to the present invention as described in detail above has the following effects.

First, the guide rail on which the drawer is mounted is provided with an elastic rotating body so that even if the inner case is deformed, the projecting degree of the rotating lever is adjusted by the elastic member of the elastic rotating body to maintain the contact state with the drawer at all times. .

Therefore, the mounting failure of the drawer due to the error in the dimensions of the drawer when mounting, or by preventing the drawer from being removed from the guide rail can be expected to ensure the effect of securing the mounting stability of the drawer.

Second, even if the drawer is somewhat deformed due to the load or temperature during the continuous use of the drawer, the active position adjustment of the elastic rotating body enables the stable mounting of the drawer so that no replacement or repair of the drawer is necessary. It is also possible to expect the effect of improving the life, it is possible to improve the quality of use by relieving the user's emotional discomfort by preventing the draw / entrance shaking of the drawer by the continuous contact of the elastic rotor and the drawer.

Third, the elastic support is in contact with the drawer by adjusting the degree of protrusion by the rotation does not cause a separate jam or resistance during the withdrawal / entry of the drawer is easy to take out / draw operation of the drawer to improve the ease of use You can expect.
