A decorative cover 11 is provided which is an injection molded product. Note that, as shown in FIG. 9, the upward opening rotation of the decorative cover 11 occurs when the upper part of the front flat portion 12 of the decorative cover 11 comes into contact with the upper end corner portion 13 of the mounting plate 9. The angle is regulated.
Moreover, the open rotational holding of the decorative cover 11 at this time is carried out by engaging and holding the upper flange 15 of the decorative cover 11 with the convex portion 14 that is integrally provided from the mounting plate 9.
The upper end of the decorative cover 11 is slightly deformed by utilizing the flexibility of the decorative cover 11 to hold it open.

is designed to prevent rattling between it and the mounting plate 9.

[Problem that the invention attempts to solve]

However, in this conventional example, due to the above-mentioned configuration, when the decorative cover 11 is rotated upward to open, the front flat portion 12 of the decorative cover 11 comes into contact with the upper end corner portion 13 of the mounting plate 9, and the decorative cover 11 is opened. Since the rotation angle is restricted, there is a risk that the decorative cover 11 may be damaged if the opening operation is performed somewhat roughly. Further, since the decorative cover 11 is held open at this time by deforming the upper end of the decorative cover, it cannot be said to be good in appearance/design. Furthermore, a separate magnet 20 and a magnetic body 21 are provided to prevent the decorative cover 11 from rattling with the mounting plate 9 due to shocks, vibrations, etc. during transportation of the refrigerator main body 1 and opening/closing of the refrigerator doors 2 and 3.
The cost was high due to the use of , and the overall commercial value was low.

This invention was made in order to solve the problems of the conventional example as described above, and it prevents damage to the decorative cover when the decorative cover is rotated upward to open, and also prevents damage to the decorative cover when the decorative cover is closed. The object of the present invention is to provide an inexpensive refrigerator with high commercial value that can prevent rattling between a decorative cover and a mounting plate without using separate parts such as magnets as in the past.

[Means for solving problems]

Therefore, in this invention, when the decorative cover is rotated upward to open, the tip of the upper flange of the decorative cover is brought into contact with the stopper piece provided on the mounting plate, and the opening rotation angle of the decorative cover is An integrally punched elastic locking piece is integrally formed with a pair of U-shaped slits in close proximity to the spindle holes of the decorative cover of the mounting plate. This object is achieved by arranging holes to form elastic protrusions.

[Effect]

With the above configuration, when the decorative cover is opened, the top end of the upper flange is received by the stopper piece, and when the decorative cover is closed, the elastic protruding piece always pushes down the decorative cover and the lower side of the decorative cover is held down. Since the flange is pressed into contact with the mounting plate, the decorative cover will not be deformed or damaged like in the past, and when closing the decorative cover, the decorative cover and mounting plate can be connected without using separate parts. This prevents rattling.

In each of the above figures, the above-mentioned conventional examples Nos. 7 to 9
The same (equivalent) components as in the drawings are indicated by the same reference numerals, and redundant explanation will be omitted.

(Structure) In Figs. 1 to 6, Fig. 9a shows a mounting plate molded from a flexible plastic material such as ABS resin by an injection molding process.
A stopper piece 23 is integrally disposed on the upper part of a. In the illustrated example, a plurality of stopper pieces 23 are arranged at appropriate intervals, but they may be a single continuous piece. 24 (FIGS. 4 to 6) is a decorative cover 11 that is rotatable upward around the supporting shafts 10 at both ends.
This is an inclined portion provided at the tip of the upper flange 15, which constitutes a part of the upper flange 15. 25 is a pair of U-shaped slits 27 adjacent to the decorative cover 11a of the mounting plate 9a and the spindle hole 26 for the spindle 10 (FIG. 3b).
The elastic locking piece 28 having elasticity formed by carving the elastic locking piece 28 is an elastic protrusion formed by integrally carving a punched hole 29 in the elastic locking piece 25 .

The structure of this embodiment other than the above-mentioned structure is substantially the same as that shown in FIGS. 7 to 9 of the prior art example.

(Operation/Function) With the above configuration, the upward opening rotation of the decorative cover 11a in this embodiment is performed by the inclined portion 24 of the upper flange 15 of the decorative cover 11a.
After passing over the elastic protrusion 28 of the mounting plate 9a, the upper flange 15 is pressed by the elastic locking piece 25 and held open at an arbitrary angle α, as shown in FIG. Further, by rotating as shown in FIG. 6, the inclined portion 24 abuts the stopper piece 23 integrally provided on the mounting plate 9a at a right angle, and the decorative cover 11a is surely opened at the opening rotation angle θ. In addition to being regulated, the upper flange 15 continues to be pressed by the elastic locking piece 25 as described above.
Since the decorative cover 11a is held open without rotating downward, the internal temperature selection knob 7 can be easily operated. Also, when the decorative cover 11a is rotated upwardly, the decorative cover 1
As shown in FIG. 6, the front flat part 12 of 1a does not come into contact with the upper end corner part 13 of the mounting plate 9a.
Since the gap D is secured, there is no fear of damaging the decorative cover unlike the conventional example.

Furthermore, as described above, since the decorative cover 11a is held open by utilizing the elasticity of the elastic locking piece 25, the decorative cover 11a is held open as in the conventional example.
It has an excellent appearance/design without deforming the a.

Note that when the decorative cover 11a is closed, the inclined portion 24 of the decorative cover 11a is always closed as shown in FIG.
is pressed in the direction of arrow A by the elastic protrusion 28 of the mounting plate 9a, and the decorative cover 1 is pushed around the support shaft 10.
Since a force is applied to push down the decorative cover 1a, the lower flange 22 of the decorative cover 11a is pressed against the mounting plate 9a in the direction of arrow B.
1a is each door 2 when transporting or using the refrigerator;
There is no rattling caused by shocks, vibrations, etc. caused by opening and closing of the device 3, and there is no need to use separate parts such as magnets or magnetic materials as in the conventional example.

(Effects of the invention) As explained above, according to this invention, the upward opening rotation angle of the decorative cover is regulated by the contact between the upper flange tip of the cover and the stopper piece of the mounting plate. Since downward rotation is prevented by the elastic locking piece of the mounting plate, when the decorative cover is rotated upward, a gap can be secured between the flat front part of the decorative cover and the upper corner of the mounting plate. This prevents the cosmetic cover from being damaged or deformed.
We can provide products with excellent design. Furthermore, when the decorative cover is closed, the elastic protrusion of the mounting plate always presses the decorative cover against the mounting plate, so there is no need to use separate parts such as magnets as in the conventional case. It was possible to prevent rattling with the mounting plate, and to provide a refrigerator with low cost and high commercial value.
