(B) Background Conventionally, in this type of storage, such as a refrigerator, in order to effectively utilize the internal volume, a plurality of removable shelves for placing articles are provided at predetermined intervals inside the storage. However, when storing items that are too large to fit into the spaces between the shelves, the shelves get in the way and it is a hassle to have to remove the shelves each time. A variety of variable-loading area shelves have been devised that can be divided into two parts, for example, and folded while stored in the refrigerator, or can be slid so that one overlaps the other, cutting the depth in half. There is.

(C) Problems with the Background Art Conventional shelves with a variable placement area have had the inconvenience of causing the articles to fall from the movable shelves if they are folded or stacked with articles placed on them.

(d) Purpose of the invention The object of the invention is to provide a shelf device with a variable placement area that prevents items from falling even if the area is changed while items are being placed there.

(e) Summary of the invention A front shelf is constructed by fixing a plurality of vertical bars to an outer frame whose both sides are slidably engaged with rails formed on both sides of the inner box of the storage box, and the front shelf of the outer frame is A front crosspiece having an abutting part that slightly protrudes upwardly on both sides, and a front crosspiece having an engaging part that protrudes downwardly on both sides with a step downwardly on both sides, and a front crosspiece that has an engaging part that protrudes downwardly on both sides. A rear shelf is constructed by spanning a plurality of vertical bars between rear bars having legs that are engaged with the rails, and the engaging portion of the front shelf is slid onto the vertical bars from above the vertical bars of the front shelf. The shelving device is configured such that the front shelf is located below the vertical crosspiece of the rear shelf in a freely engaged state, and the front shelf is overlapped with the lower part of the rear shelf to change the placement area. However, during polymerization, even if an item is left on the front shelf by mistake, it will get caught between the contact part and the front crosspiece during polymerization, making it impossible to polymerize and preventing the item from falling. To prevent.

(F) Embodiment of the invention FIG. 1 shows a side cross section of a refrigerator 1 as an embodiment of the storage. The refrigerator 1 is formed by filling a space between an outer box 2 and an inner box 3 with a heat insulating material 4, and on the left and right side walls of the inner box 3, sliding rails 5 recessed in the direction of the heat insulating material 4 are provided horizontally in the front-rear direction and vertically. A plurality of sliding rails 5 are formed at predetermined intervals, and the shelf device 6 of the present invention is engaged and supported by the sliding rails 5.

The shelf device 6 consists of a front shelf 7 and a rear shelf 8, as shown in the perspective view of FIG. 2 and the sectional view of FIG. The front shelf 7 and the rear shelf 8 are formed by coating a metal material with resin. The front shelf 7 is formed by fixing a plurality of vertical bars 10 in the front-rear direction to an outer circumferential frame 9 bent into a rectangular shape by spot welding or the like. The width of the outer peripheral frame 9 is such that the left and right sides 9a and 9b are slidably engaged with the sliding rails 5 of the inner box 3. Further, the depth of the front shelf 7 is set to be approximately 1/2 of the depth of the sliding rail 5. A decorative member 11 made of synthetic resin is fitted and fixed to the front side 9c of the outer peripheral frame 9. The decorative member 11 extends to above the front end of the vertical bar 10 and contacts the abutting portion 1.
2. The rear shelf 8 has a front crosspiece 13 having engaging portions 13a and 13b bent to have a substantially L-shaped cross section so as to protrude laterally with a slight step downwardly on both left and right sides, and a front crosspiece 13 having a lower side on both left and right sides. It is formed by fixing a plurality of vertical bars 15 across and fixed between rear bars 14 having leg portions 14a, 14b projecting laterally with a small step. The width of the rear crosspiece 14 is the width of the leg portion 14
a, 14b are dimensioned to engage with the sliding rail 5 of the inner box 3, and the width of the front crosspiece 13 is the same as the engaging portions 13a, 14b.
13b is the vertical beam 1 located at both left and right ends of the front shelf 7
The dimensions are the same as those of 0a and 10b.
Since the rear crosspiece 14 is formed slightly upwardly to prevent objects from falling, the rear crosspiece 15 is bent upward in order to keep it horizontal. Further, the depth dimension of the rear shelf 7 is also approximately the same as that of the front shelf 8.

Next, the explanation for assembling the shelf device 6 will be explained with reference to FIG. Insert. As it is, rotate the rear shelf 8 counterclockwise in FIG. 4 to engage the left side engaging part 13a with the lower vertical bar 10a of the front shelf 7 so that both vertical bars 10 and 15 are parallel to each other. . At this time, the vertical bar 10 is located below the vertical bar 15. In this state as shown in FIG. 2, the shelf device 6 assembled in this manner is engaged and placed on the sliding rail 5 of the inner box 3. At this time, the left and right sides 9a of the outer peripheral frame 9 of the front shelf 7,
9b is slidably engaged with the sliding rail 5 in the front and rear direction, and is connected to the left and right legs 14a, 14b of the rear crosspiece 14 of the rear shelf 8.
is engaged and fixed to the inner part of the sliding rail 5.

Next, the operation will be explained with reference to FIGS. 5 and 6. Fifth
The figure shows a state in which the mounting area of the shelf device 6 is maximized, and in this case, an engaging portion 13 is attached to the rear side 9d of the outer peripheral frame 9 of the front shelf 7.
a and 13b are in contact with each other, and most of the area of the front shelf 7 and rear shelf 8 can be used as a mounting surface.

Next, when tall items such as 1-sho bottles are stored and a part of the shelf device 6 gets in the way, push the front shelf 7 to the back and slide it along the sliding rail 5 to the rear shelf 8 as shown in Figure 6. The front shelf 7 is overlapped with the lower part. At this time, the mounting area of the shelf device 6 is reduced to only the area of the rear shelf 8. In this state, the front side 9c of the outer peripheral frame 9 of the front shelf 7 is connected to the engaging part 13 of the front crosspiece 13 of the rear shelf 8.
a, 13b. This creates a relatively large space in front of the shelf device 6, allowing tall items to be stored therein. If the front shelf 7 and the rear shelf 8 are stacked together, and if you accidentally push the front shelf 7 below the rear shelf 8 with the article placed on the front shelf 7, the article on the front shelf 7 will be moved to the rear shelf 8. Front pier 13
In this state, the front shelf 7 is further pushed in, and eventually the abutting part 12 of the decorative member 11 comes into contact with the article, and the article is sandwiched between the abutting part 12 and the front crosspiece 13 at the lower part. The front shelf 7 cannot be pushed in any further. This prevents objects from falling.

(g) Example of application of the invention Although the invention is applied to a refrigerator in the embodiment, the invention is not limited to this, but is also effective when applied to a freezer, a refrigerated case, a hot storage, and the like.

(H) Effects According to the shelving device of the present invention, the placement area can be easily changed depending on the size of the stored items, the trouble of removing the shelves is eliminated, and the storage volume can be used effectively. Furthermore, even if you attempt to stack the front shelf onto the rear shelf with items placed on the front shelf, the items on the front shelf will be caught between the abutment part and the front crosspiece and will no longer be able to be stacked. There is no danger of it falling. Furthermore, when configuring the projecting shelf device, assembly is easy because it can be accomplished by simply engaging the front crosspiece engaging portions of the rear shelf with the vertical crosspieces on both sides of the front shelf.
Since the rail of the inner box can also utilize the conventional shelf engagement groove, it has practical effects such as being suitable for mass production.
