Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric refrigerator (to be referred to as a refrigerator hereinafter), and more particularly to the structure of a refrigerating compartment shelf and its support.

[0002]

2. Description of the Related Art Refrigerators include a freezing room, a refrigerating room, a vegetable room, and the like.
This shelf is supported by a shelf receiving portion formed on the side surface of the inner box or the like. Since the shelf receiving portions are formed in a plurality of stages at predetermined intervals, the height of the shelves can be adjusted.

[0003]

However, in the conventional refrigerator, since the shelves cannot be moved vertically while being held substantially horizontally in the refrigerator, when the height of the shelves is changed, the shelves are once pulled out and put in again. There was a need. Moreover, when putting the shelf in and out, there is a risk that the item may fall or drop, so it is necessary to take out only the item first, and the taken out item must be stored again after adjusting the shelf position, It was inconvenient to handle. Therefore,
An object of the present invention is to provide a refrigerator in which the height of shelves can be easily changed in the refrigerator.

[0004]

The present invention SUMMARY OF] has been made to solve the above problems, a projection provided on at least the front and rear on both sides of the shelf to be inserted in a refrigerator, each of said shelf
From each cylindrical chamber corresponding to the protrusion and the peripheral surface of the cylindrical chamber
Support body having a plurality of extended support grooves having different heights
In the refrigerator in which the inner box side wall of the refrigerator is fixed,
Rotate in the cylindrical chamber while supporting the protrusion in the cylindrical chamber,
It is possible to move the supporting protrusion to the desired supporting groove.
I tried to provide a rolling body.

[0005]

According to the above construction, the rotating body for switching the supporting position of the projections is provided on the supporting body fixed to the side wall of the refrigerating chamber while supporting the projections formed on the front and rear sides of both sides of the shelf. The height of the shelves can be changed without pulling the shelves out of the refrigerator compartment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, 1 is a shelf, and 2 and 3 are supports formed in contrast with the shelf 1 sandwiched therebetween. The shelf 1 is formed in a box shape, and projections 4 are provided on the front and rear sides of both sides.
A switching device 5 for switching the height (supporting position) of each projection 4 between upper, middle, and lower is provided on the support bodies 2 and 3 on both sides which support the projection 4 (shelf 1). The switching device 5 is shown in FIG.
As shown in FIG. 5, the bottomed cylindrical chamber 6 and the support grooves 7a, 7 extending separately from the peripheral surface of the bottomed cylindrical chamber 6 into upper, middle and lower stages.
b, 7c, a rotary body 8 that rotates in a bottomed cylindrical chamber 6 while supporting the projection 4 on the lid 1 side, and a rotary body cover 9 that covers the rotary body 8. The rotating body 8 is formed with a recess 8a having an opening on the peripheral surface thereof. This recess 8
Reference character a denotes a place where the protrusion 4 temporarily enters when the support position of the protrusion 4 of the shelf 1 is changed, and its opening corresponds to the entrance to the support grooves 7a, 7b, 7c. Further, a stopper pin 8b is provided on the surface of the rotating body 8 and a plurality of stoppers 9a are formed on the inner circumference of the rotating body cover 9. The role of these stopper pins 8b and stoppers 9a is to rotate the rotating body 8 stepwise so that the concave portions 8a are supported by the supporting grooves 7a, 7b,
This is for keeping the state of being fitted to the entrance of 7c as well as being fitted to the entrance.

FIG. 3 shows a part of the refrigerating compartment, which is an inner box 10
Clamping portions 10a, 10b for clamping the support bodies 2, 3 on both side walls of the
Are formed. In order to store the shelf 1 and the supports 2 and 3 in the inner box 10 side, first, the shelf 1 and the supports 2 and 3 are combined, and both supports 2 and 3 are simultaneously pushed into the holding portions 10a and 10b to hold them. . This completes the assembly, but with such a configuration, for example, when the recess 8a is in the position as shown in FIG. 2 and the protrusion 4 of the shelf 1 is supported by the upper support groove 7a, the shelf 1 is removed. When pulled to the side of the rotating body 8, the protrusion 4 also moves to the side of the rotating body 8 and is set in the recess 8 a of the rotating body 8. When a downward force is applied to the shelf 1 in such a state, the rotating body 8 rotates clockwise, and the opening of the concave portion 8a and the support groove 7b.
Match the entrance of. When a downward force is further applied to the shelf 1, the shelf 1 is further rotated and the entrance of the support groove 7c is fitted. Thus, when the opening 8a of the rotating body 8 is aligned with the entrance of the support groove 7b or 7c, the shelf 1 is moved to the support groove 7b or 7c side.
The height of can be changed. In addition, the support grooves 7a, 7
Since the rear bottom surfaces of b and 7c are provided with some recesses, the movement of the shelf 1 is restricted, and the shelf 1 does not move when the articles are taken in and out.

[0008]

According to the refrigerator as described above, the protrusions on both sides of the shelf are supported by the support fixed to the side wall of the refrigerating compartment, and the support positions of the protrusions are set to upper, middle, and lower positions.
Since a switching device for switching to the bottom is provided, the height of the shelf can be changed without pulling out the shelf from the refrigerating room, and moreover, the height of the shelf can be changed while the items are placed on the shelf. It is convenient.
