Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mounting device for a rail shelf that is removably installed above a partition plate that forms the floor of a refrigerator.

[Conventional technology]

For example, in the conventional MR-2754V type refrigerator manufactured by Mitsubishi Electric ■, as shown in Figs. 4 and 8, the ABS
The reinforcing plate 21 is temporarily fixed to the inner box 3 formed by vacuum forming using plastic such as the like, using rivets 33a, 33b, etc., and a heat insulating material 10 such as polyurethane foam is completely filled between the outer box 2 and the inner box 3. . Next, attach the fixture 20 to the screw 32.
This mounting tool 20 is fixed to the reinforcing plate 21 via the inner box 3.
The engagement grooves 22a and 22b of the rear wall 1 of the rail shelf 16
The rail shelf 16 is supported by a mounting portion 19 having an engaging portion 37 having a substantially U-shaped cross section that is integrally installed in the mounting portion 8 .

[Problem that the invention seeks to solve]

However, in the above conventional device, after the reinforcing plate 21 is temporarily fixed to the inner box 3 with rivets 33a and 33b, the heat insulating material l is removed.
Since the fittings 20 are attached to the inner box 3 after filling with O, it is difficult to carry the reinforcing plate 21 temporarily fixed to the inner box 3 or when inserting the inner box 3 into the outer box 2. Since the product is thin and weak, the reinforcing plate 21 easily comes off, and to prevent this, it was necessary to further fix the reinforcing plate 21e to the inner box 3 with tape 36. Also, when filling the insulation material 10, the insulation material 10 enters between the inner box 3 and the reinforcing plate 21, and the fitting 20
The surface of the inner box 3 that comes into contact with the inner box 3 is deformed, the fixture 20 is tilted, and the rail shelf 16 is also engaged with the rail shelf 16 tilted, resulting in a decrease in the design value. In order to eliminate this drawback, reinforcing plate 2
An intrusion prevention tape 34 of the heat insulating material 10 is adhered to the contact surface of the rail shelf 16 to the inner box 3. This tape 34 acts as a cushion between the fixture 20 and the reinforcing material 21, and the rail shelf 16
There was a drawback that the sun was setting. In addition, the square hole portion 30 of the reinforcing plate 21
In order to prevent the heat insulating material lO from leaking into the inner box 3 through the square holes 28 and round holes 29 of the inner box 3, a paper tape 35 is also required, resulting in high cost. In addition, the square hole 28,
Reference numeral 30 is for inserting the inner box insertion guide part 23 which stands upwardly through the entire horizontal base part 24 at the upper part of the back of the fixture 20, and the round holes 29 and 31 are provided at the lower part of the back of the fixture 20. The provided space is for inserting a boss 25 for positioning with the nine-yen box 3.

The present invention was made to solve the above-mentioned conventional problems, and does not require tape or the like, is simple in construction and inexpensive, and does not cause leakage of the filled insulation material or rattling of the rail shelf. An object of the present invention is to provide a rail shelf mounting device for a refrigerator.

[Means for solving problems]

In the present invention, the rail shelf fixtures and the reinforcing plate for the inner box are attached to the inner box before filling with the heat insulating material.

[Effect]

Before filling with insulation material (Since it is attached to the mounting bracket and reinforcing sheet metal inner box, it is strong and does not require fixing with tape, etc.) Further, since the fitting functions as a lid, there is no leakage of the heat insulating material into the inner box, and since the inner box and the reinforcing plate are firmly attached, there is no leakage of the heat insulating material between them.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In Figs. 1 to 3 and Figs. 5 to 7, ■ is a refrigerator body having an outer box 2 and an inner box 3, and inside the inner box 3, from above, there is a freezer compartment 4, a refrigerator compartment 5, and a vegetable compartment. 6 is partitioned. Reference numerals 7 to 9 denote a freezer compartment door, a refrigerator compartment door, and a vegetable compartment door, which are arranged so as to cover the @ side frontage of the refrigerator main body 1, respectively.

11 is a low-temperature case provided at the top of the refrigerator compartment 5 for storing food such as meat and fish; 12 is a temperature control knob provided at the upper back of the refrigerator compartment 5; and 13 and 14 are located inside the refrigerator compartment 5. Upper and lower shelves are provided.

Reference numeral 5 is a partition plate that forms the floor surface at the bottom of the refrigerator compartment 5. The rail shelf 16 is located slightly above the partition plate 15, and the sliding rail of the telescopic shelf 17 is entirely provided on one side. The telescoping shelf is rotatable around the rear end shaft and can be extended and contracted in the front and rear directions. Further, the mounting tool 20 is provided with a convex portion 27 for attaching screws for fixing to the inner box 3, and the inner box 3
Protrusions 26a and 26b for temporary fixing are provided on the positioning plate 25.
e, and a reinforcing plate 2 is provided at the tip of the guide part 23 for inserting the inner box.
1. A sloped portion 38 is provided to serve as a guide during installation.

Next, a procedure for attaching the rail shelf attaching device having the above configuration to the inner box 3 will be explained. First, the inner box insertion guide part 23 of the fixture 20 is inserted into the square hole 28 provided in the inner box 3, and the temporary fixing convex part 26a provided in the goth 25 of the fixture 20,
Positioning round hole 29 with dimensions slightly smaller than width A of 26b
The fitting 20 is temporarily fixed to the inner box 3 by inserting it while wrapping the boss 25. Next, square holes 30 and round holes 31 corresponding to the guide portions 23 and posts 25 of the temporarily fixed fixture 20 are provided in the reinforcing plate 21, and the reinforcing plate 21 is brought into contact with the back side of the inner box 3 and slid. While rotating, the square hole 30 is fitted into the root part 24 through the inclined part 38 of the side part 23, and the screw 25 is inserted into the round hole 31. Next, the temporarily fixed fitting 20 and reinforcing plate 21 are screwed together from the reinforcing plate 21 side using screws 32, etc., and before filling the inner box IO with the insulation material IO.
The fixture 20 and reinforcing plate 21 are fixed to.

〔Effect of the invention〕

As described above, in the present invention, the fittings and the reinforcing plate are attached to the inner box before filling with the heat insulating material, and the tape for temporary fixing is not used for public safety because it increases the strength. Also, since the fittings act as a lid, there is no leakage of insulation material into the inner box.
No paper tape is required to prevent this. Furthermore, since the inner box and the reinforcing plate are securely attached, there is no leakage of the insulation material between them, and there is no need for tape to prevent heat material from entering the dead space as it acts as a cushion between them. Therefore, the structure is simple and inexpensive, and manufacturing is also easy, and rattling of the rail shelf can be prevented.
