[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf device that improves the handling of food stored in a refrigerator.

[0002]

2. Description of the Related Art In recent years, from the ergonomic point of view, the number of products approached from the human side has increased, such as reducing the burden on human motion. The same applies to the ease of use when putting items in and out of the refrigerator, especially for items placed on shelves at the top of the refrigerator, which makes it difficult to put them in and take them out, so that you should forget to use them and waste them. Therefore, it is proposed to add a device to the shelf to improve the usability of this part.

A conventional refrigerator provided with a shelf device for improving the usability of the upper shelf in the refrigerator is disclosed in Japanese Patent Laid-Open No. 6-101960.
There is one disclosed in the official gazette.

The conventional shelving device will be described below with reference to the drawings.

FIG. 18 is a front view of a conventional refrigerator. FIG. 19 is a sectional view taken along the line AA of FIG. Figure 20
FIG. 6 is a cross-sectional view showing the operation of a conventional refrigerator shelf device.

In FIGS. 18, 19, and 20, 1 is a refrigerator body, 2 is an outer box, 3 is an inner box, 4 is a heat insulating material filled between the outer box 2 and the inner box 3, and the refrigerator body 1 Is composed of an outer box 2, an inner box 3 and a heat insulating material 4. Reference numeral 5 is a storage room partitioned in the refrigerator main body 1, 6 is a shelf located in the uppermost stage installed in the storage room 5, and 7 is another shelf. 8 is 8
The arm link mechanism includes a pair of a and 8b, and is provided on the left and right of the uppermost shelf 6. 9 is a connecting member,
The arm link mechanisms 8a and 8b are connected. Reference numeral 10 denotes a rotatable support shaft provided at the lower end of the arm link mechanism 8 and is composed of front and rear support shafts 10a and 10b.

Numerals 11 and 12 are arms of the arm link mechanism 8, which are arranged in parallel in front and rear at a constant interval W, and the lower ends of the respective arms are rotatable shafts 10a and 10b which are symmetrically positioned on both walls of the refrigerator. Supported by. Also, the arm 11,
The upper end of 12 is held by the connecting member 9 so that the space W is maintained and it can rotate.

The operation of the arm link mechanism of the shelf device of the refrigerator constructed as above will be described below.

First, when the uppermost shelf 6 is pulled out forward, a rotation operation occurs around the support shaft 10 of the arm link mechanism 8. That is, the arms 11 and 12 operate with the support shafts 10a and 10b as fulcrums, and the uppermost shelf 6 is moved diagonally downward and forward by a linear distance while being kept horizontal by the arm link mechanism 8.

[0010]

However, according to the conventional structure, since the length L of the arms 11 and 12 of the arm link mechanism is an operation locus, the locus is large and a wide space is required in the front. It is necessary for the human to move backward during the motion, and the motion trajectory is large, which makes the human uneasy. Further, in order to move the rear of the uppermost shelf 6 from the inside to the outside, the length L of the arms 11 and 12 is L.
However, there is a drawback that the arm link mechanism becomes large because it requires the movement distance.

The present invention solves the conventional problems, and an object of the present invention is to provide a refrigerator shelf device having a small operation locus and a compact mechanism.

Further, since the uppermost shelf 6 draws a locus that moves obliquely downward and forward outside the refrigerator with a straight line distance, it interferes with the articles placed on the shelf directly below it. There is also a drawback in that the effective space in the refrigerator is wasted by lowering the shelves below and setting them more than necessary, or by limiting the storage height of the articles.

Another object of the present invention is to provide a shelving device which does not interfere with the items directly below it when the shelves are moved.

Further, in the conventional structure, since the operation is performed only by the arm link mechanism, there is a drawback that the horizontal movement becomes unstable depending on the load of the stored items.

Another object of the present invention is to smoothly perform horizontal operation regardless of the contents stored in the shelves.

Further, the conventional structure has a drawback that acceleration occurs during downward movement due to the load of the stored items.

Another object of the present invention is to reduce the force exerted on the downward movement.

[0018]

In order to achieve this object, the present invention has two pairs of bending arm link mechanisms on the left and right sides of the shelf.

As a result, the movement locus of the shelf is small and the arm link mechanism can be made compact.

Further, guides for horizontally moving the shelves are provided at both ends of the shelves.

As a result, the forward horizontal movement can be smoothly performed regardless of the stored items.

Further, a spring is provided at the connecting portion of the arm link mechanism which is bent in two.

As a result, the acceleration of descending the shelves can be kept small.
