[Problem that the invention attempts to solve]

As described above, the conventional tray 13 is simply placed on the square hole 12 of the rail shelf 7,
When taking out the stored items in the back of the tray 13, the stored items in the front may get in the way and cause the stored items in the front to fall over, and when taking out the stored items stored on the partition plate 6 at the bottom of the rail shelf, the stored items may get in the way. There was a risk that the tray 13 would be pushed up by an object and fall from the top of the rail shelf 7. Furthermore, the tray 13 may be damaged by the rail shelf 7 due to impulses, vibrations, etc. during transportation of the refrigerator.
In order to prevent it from falling from above, it is necessary to fix the tray 13 to the rail shelf 7 each time using fixing tape 17 or the like, which is very time-consuming, expensive, and less practical. Ta.

This idea was made to solve the problems of the conventional method as described above, and allows objects stored at the back of the slide tray to be easily taken out from the front without tipping over. To provide a refrigerator with high practical value, in which there is no fear that the slide tray will fall off from the rail shelf even if the slide tray is pushed upward by the stored object when taking out the stored items on the lower partition plate of the shelf. The purpose is

[Means for solving problems]

The slide tray is slidably/removably mounted on the back rail and the front frame, and the tip of the side rail is provided with a guide piece for guiding the rear end side flange of the slide tray and a stopper piece extending downward. In addition, a locking piece protruding from the side wall of the slide tray is provided at the rear of the slide tray to restrict forward movement of the slide tray and to allow the slide tray to be pulled out fully forward. At this time, a guide piece extending rearward from the locking piece is brought into contact with a protruding rib protruding below the side rail to restrict downward tilting of the slide tray. This aims to achieve the above objective.

[Effect]

With the above configuration, when the slide tray placed on the sliding rail of the side rail of the shelf is slid horizontally toward the front and pulled out, the guide piece comes into contact with the protruding rib and moves the tray downward. Since the tilting of the tray is prevented, items stored at the back of the tray can be easily taken out from the front without tipping over. Also, when taking out items stored on the lower partition plate of the shelf, if the items stored in the tray are Even if the tray is pushed up, the locking piece will come into contact with the lower side of the side rail, eliminating the fear that the tray will fall off the shelf.

is the tray 2 located directly below each food placement rib 38.
When the tray 29 slides in the front-rear direction, the sliding ribs 39 are slidably placed on the front frame 21 of the rail shelf 7. This is intended to prevent the bottom surface 30 of the tray 29 from being scratched.

The structure of this embodiment other than the above-mentioned structure is substantially the same as that shown in FIGS. 8 to 10 of the prior art example.

(Operation) The slide tray 29 configured as described above usually allows the side flange portion 32 of the tray 29 to slide on a pair of slide rails 22 that are integrally provided on each side rail 19 of the rail shelf 7. When taking out the stored items on the partition plate 6 at the bottom of the rail shelf 7, even if the stored items push up the bottom surface 30 of the tray 29, the locking pieces 35 comes into contact with the lower side of the side rail 19 of the rail shelf 7, and there is no fear that the tray 29 will fall off from the top of the rail shelf 7. Moreover, when taking out the stored items stored in the back of the tray 29, the side flange portion 32 of the tray 29 is slidably placed on the sliding rail 22 of the rail shelf 7, so that the tray 29 can be removed as shown in the dashed-dotted line in FIG. Since the tray 29 can be smoothly pulled out forward until the locking piece 35 of the tray 29 comes into contact with the stopper piece 23 of the rail shelf 7 as shown in dimension C, the tray 29 can be easily taken out.

Note that when the tray 29 is pulled out fully forward as described above, even if a relatively heavy object is placed on the front part of the tray 29 and the tray 29 attempts to tilt downward, the locking piece of the tray 29 will not move. The upper surface of the guide 36 extending rearward from the guide 35 comes into contact with the lower surface of the protruding rib 26 formed to protrude downward from the side rail 19 of the rail shelf 7, and the downward inclination of the tray 29 is regulated. The tray 29 can be pulled out all the way to the front in a substantially horizontal state, and there is no fear that the items stored on the tray 29 will fall over. Furthermore, tray 2

is pushed upwards elastically and the tray 29 can be removed from the rail shelf 7, making cleaning etc. easy. It can accommodate a large amount of material. In addition, to reinstall the tray 29 on the rail shelf 7, as shown by the arrow S in FIG. By pushing the tray 29 backward, the tray 29 can be installed and set as easily as it is removed.

As described above, in the structure in which the tray 29 is detachably attached to the rail shelf 7, when the tray 29 is set on the rail shelf 7 for normal use as shown in FIG. Gap dimensions A and B between 28 and the front flange 34 of the tray 29
Since the stopper part 37 of the tray 29 comes into contact with the guide piece 25 of the rail shelf 7 and restricts the movement of the tray 29 in the left-right direction, the dimension A≒B can be maintained approximately, and the gap dimension By making it uniform, it looks very good in terms of design.

Note that since the slide tray 29 is made of a transparent plastic material, it is possible to easily distinguish the items stored on the lower partition plate 6 of the tray 29, and the bottom surface 3 of the tray 29 can be easily distinguished.
The sliding rib 39 prevents the front frame 21 of the rail shelf 7 from being scratched when the rail shelf 7 is slid. Since it is disposed directly below the food placement rib 38, it is hidden from view and does not reduce the product value.

Note that FIG. 7 shows another embodiment corresponding to FIGS. 5 and 6, in which the slide tray 29
A convex rail 40 is integrally formed from the lower surface of the side flange portion 32, and the convex rail 40 is guided in a concave groove portion 41 integrally provided on the upper surface of the rail shelf 7, so that the tray 29 can be moved back and forth on the rail shelf 7. The convex rail 40 is engaged with the groove 41 to restrict the movement of the tray 29 in the left and right direction, and the same effects as in the embodiment described above can be obtained. Of course.

[Effect of idea]

As explained above, according to this invention, by horizontally sliding the tray placed on the shelf in the front direction, the items stored at the back of the tray can be moved between the guide pieces and the protruding ribs. Due to the contact action of the tray, it is possible to easily take out items from the front without tipping over, and even if the tray is pushed up by the item when taking out the items on the lower partition plate of the shelf, it will not lock. There is no risk of the tray coming off the shelf and falling off due to the piece hitting the lower side of the side rail. Therefore, the conventional fixing tape can be eliminated, and a refrigerator with high practical value can be provided.
