Benefits of technology

[0033] According to the present invention as described above, it is possible to enhance the safety and convenience in use of a final product.

Problems solved by technology

However, the above-mentioned conventional refrigerator storage box extracting / retracting apparatus has problems as follows.
As a result, a part of a user's body may be caught in between the refrigerator body 10 and the storage box, whereby the user may be injured.
Furthermore, if the velocity of the storage box retracted into the storage space 11 is increased, an impact or noise may occur while the storage box is being received in the storage space 11.
As a result, the bottom wall of the storage box may sag due to the food contained in the storage box.
As a result, the storage box is not readily extracted or retracted due to the frictional force between the bottom wall of the storage space 11 and the bottom surface of the bottom wall of the storage box.

first embodiment

[0044]FIG. 1 is a perspective view showing a firs embodiment of the inventive refrigerator storage box extracting / retracting apparatus, and FIG. 2 is a perspective view showing the inventive refrigerator storage box extracting / retracting apparatus in a state in which a storage box is received within a storage space of a refrigerator.

[0045] As shown in the drawings, a rail assembly 30 according to an embodiment of the present invention has a guide rail 32 which is formed to be elongated in the longitudinal direction. Each of the opposite side walls of a storage space formed in a refrigerator body is provided with such a guide rail 32 in such a manner that the guide rail 32 extends in the front-to-rear direction of the storage space. At this time, the guide rail 32 is installed in such a way that the right end of the guide rail 32 as viewed in FIG. 1 is directed toward the front side of the storage space.

[0046] In order to fix the guide rail 32 to a corresponding side wall of the sto...

second embodiment

[0074] Now, the inventive refrigerator rail assembly and the inventive refrigerator storage box extracting / retracting apparatus having the same will be described in more detail with reference to FIGS. 5 to 7.

[0075]FIG. 5 is an exploded perspective view of the second embodiment of the inventive refrigerator storage box extracting / retracting box, FIG. 6 is a perspective view showing the second embodiment in a state in which the storage box is received in a space of a refrigerator, and FIG. 7 is a longitudinal section view schematically showing a main part assembled in the second embodiment.

[0076] As shown in the drawings, a rail assembly 130 is installed on the bottom wall of a storage space 110 formed in a body of a refrigerator. In other words, although the rail assemblies 30 are installed on the opposite side walls of the storage space in the above-mentioned first embodiment to extend in the front-to-rear direction, according to the present embodiment, the rail assembly 130 is ins...

Abstract

Disclosed is a refrigerator rail assembly for guiding a storage box while the storage box is being extracted from or retracted into a space of a refrigerator. The refrigerator rail assembly includes: a guide rail provided on a side of the storage space to extend in the front-to-rear direction of the storage space, the guide rail having a guide channel formed in the longitudinal direction of the guide rail and opened at a side thereof; a movable rail having a guide channel formed in the longitudinal direction of the movable rail and opened at a side opposed to the guide channel of the guide rail, the storage box being removably installed to the movable rail; an intermediate rail having a pair of guide flanges which are inserted into the guide channels, respectively; and a plurality of ball bearings interposed between the guide channels and the guide flanges. The guide rail and the movable rail move in relation to the intermediate rail, so that the storage box is extracted from or retracted into the storage space.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a refrigerator, and in particular to a refrigerator rail assembly for guiding a refrigerator storage box while the storage box is being extracted from or retracted into a storage space of the refrigerator, and a refrigerator storage box extracting / retracting apparatus having such a rail assembly. [0003] 2. Description of the Prior Art [0004] A refrigerator is provided with a storage space within the body thereof, which is selectively opened or closed by a door. The door may be a pivotable type or a slidable type in opening or closing the storage space. In particular, if the door is a slidable type in opening or closing the storage space, a refrigerator storage box is provided within the storage space in such a manner that the storage box can be extracted from or retracted into the storage space simultaneously when the storage space is opened or closed. In addition, there is also prov...
