On the other hand, the shelf 400 is mounted to the groove 142 and the restricting protrusion 144 formed as described above.

The shelf 400 is composed of a frame formed along the edge of the support 410 and the support 410 is the food is seated on the upper surface as shown in FIG.

The frame is spaced apart from the outer frame 420 forming both sides of the shelf 400 by a distance corresponding to the protruding length of the groove 142 from the outer frame 420. It consists of an inner frame 440 is formed in parallel with.

In addition, the inner frame 440 is further provided with a stripping prevention rib 422 and the above-described elastic protrusions 460 extending in the direction toward the outer frame 420 having a predetermined area at the rear end.

The stripping prevention rib 422 is configured to prevent the shelf 400 from being removed in contact with the bottom surface of the groove 142 in a state where the shelf 400 is mounted on the groove 142. In addition to the removal prevention function, the sliding drawer / entrance of the shelf 400 also serves as a guide at the same time.

On the other hand, the inner frame 440 is a predetermined portion is excised so that the projection protrusion groove 444 is formed so that the central portion of the elastic projection 460 to protrude in the direction of the outer frame 420, the projection protrusion Fixing pieces 442 for fixing both ends of the elastic protrusion 460 are further provided at both sides of the groove 444.

”와 같이 삼각형상의 좌우 대칭구조로 형성된다.Looking at the shape of the elastic protrusion 460 in order to explain in more detail, the elastic protrusion 460 is formed with one leaf spring is bent at the central portion at a predetermined angle, both ends are bent to the outside again to approximately "

”Is formed in a triangular symmetrical structure.

Therefore, a central portion of the elastic protrusion 460 is inserted into the protrusion protrusion groove 444 in the direction of the outer frame 420, and both ends thereof are fixed to the fixing piece 442 at the inner side of the inner frame 440. The position is fixed by this (see enlarged view of FIG. 3).

Hereinafter, the operation of the shelf fixing structure of the refrigerator according to the present invention having the structure as described above will be described in detail with reference to the accompanying drawings.

In the refrigerator employing the present invention, both sides of the rear half of the shelf 400 are seated on the grooves 142 formed on the front side of the plurality of grooves 142 protruding the shelves 400 from both sides of the inner case 140. Let's go. And, as described above, when both rear half portions of the shelf 400 are seated on the front groove 142, the shelf 400 is pushed to the rear side.

At this time, the elastic protrusion 460 mounted to protrude in the direction of the outer frame 420 from the inner frame 440 of the shelf 400 interferes with the restraining protrusion 144 protruding from the position adjacent to the front groove 142. While being elastically compressed, when the shelf 400 is further introduced to the rear side, the interference with the restraining protrusion 144 is terminated and elastically restored.

As described above, the elastic protrusion 460 is restored to form a “click”, and when the user pushes the shelf 400 further to the rear side, the restraining protrusion (a) adjacent to the rear groove 142 ( 144 and the elastic protrusion 460 once again interfere with the central portion of the elastic protrusion 460 is located between the restraining protrusion 144 and the groove 142.

In such a state, the elastic protrusion 460 maintains a state in which the surface between the groove 142 and the restraining protrusion 144 has elastic contact, thereby firmly maintaining the mounted state of the shelf 400. As described above, in order to further strengthen the mounting state, the surface between the constraining protrusion 144 and the groove 142 may be formed to protrude more than the surroundings to increase the elastic deformation degree of the elastic protrusion 460. It is possible.

In addition, when the finished product refrigerator is moved while the shelf 400 is mounted as described above, even when the refrigerator is laid in the horizontal direction, the shelf 400 is an elastic protrusion 460 and a restraining protrusion 144 that restrains it. And the mounting position by the groove 142 is maintained. In addition, the anti-separation rib 422 formed at the rear end of the inner frame 440 of the shelf 400 is located below the lower surface of the rear groove 142, thereby preventing the shelf 400 from being removed upward. do.

On the other hand, with reference to the accompanying drawings for the process of removing the shelf 400 mounted as described above from the inner case 140 will be described.

4 is a cross-sectional view taken along the line A-A 'of FIG. 2, and the shelf 400 is drawn out slightly in the state of being mounted on the inner case 140.

As shown in the figure, as the shelf 400 is pulled forward, the elastic protrusion 460 between the groove 142 formed on the rear side and the restraining protrusion 144 terminates the interference with the rear restraining protrusion 144. While being easily drawn out between the restraint protrusion 144 and the restraint protrusion 144 forward.

In addition, the front protrusion of the shelf 400 is limited while the restraining protrusion 144 and the elastic protrusion 460 formed on the front side are restricted, and the elastic protrusion between the restraining protrusion 144 and the front groove 142. As the 460 is positioned, the shelf 400 is stably maintained in a state in which the shelf 400 is pulled forward by a predetermined length.

On the other hand, when the user lifts the shelf 400 upward in the above state, it is possible to remove the shelf 400 at the point where the elastic restoring force of the elastic protrusion 460 is released, in this case the shelf The anti-separation rib 422 formed at the rear end of the inner frame 440 of 400 is not positioned below the rear groove 142.

Of course, when the user pulls the shelf 400 with a stronger force, the elastic protrusion 460 that interferes with the front groove 142 may be elastically deformed and pulled forward. It may be one way to remove the 400 from the inner case 140, but excessive force may be required depending on the elasticity of the elastic protrusion 460, and there is a risk of damage when excessive force is applied. It would be desirable.

According to the present invention having the configuration and operation as described above there is an advantage that the fastening relationship between the shelf and the inner case mounted on the inner case of the refrigerator is more robust.

Therefore, when carrying the finished product refrigerator there is an advantage that a separate fixing means such as adhesive tape is not required to fix the shelf and the inner case, there is an advantage that the transport process is simplified.

In addition, as above, the shelf is firmly fixed to the inner case without the use of adhesive tape, so that no defect occurs on the surface of the product due to the adhesive tape, so that the user can check the neat internal space when receiving the finished product. Satisfaction with the effect is increased.

In addition, the impact sound is generated by the elastic deformation of the elastic projection when the shelf is mounted, it is easy to check the correct mounting position of the shelf, and the elastic even when the shelf is pulled out a certain length forward There is an advantage that the shelf is more easily supported by elastically supporting the shelf between the grooves and the constraining protrusions formed at the front side.
