11) and (12) are supporting members arranged opposite to each other at appropriate locations such as the inner wall of the storage chamber (5), and sliding grooves (13) and (14) formed in concave shapes are provided on their respective opposing surfaces. ,
Support pins (9) and (40) are fitted and engaged with this.

A conventional storage opening/closing device is configured as described above, and the auxiliary storage chamber (7) is always closed by the cover plate (8). When using the auxiliary storage room (7), follow the arrow A in Figure 6.
As shown in , - Pull the lower end of the cover plate (8) forward, rotate it upward by 90 degrees to make it horizontal, and then push it in as shown by arrow B to release the support pins (9) and (10). are sliding grooves (13) of the support members (11) and (12).

(4), and the lid (8) is located in the auxiliary storage room (7).
The auxiliary storage room (7) is opened.

If the auxiliary storage chamber (7) is to be closed, the cover plate (8) can be pulled out in the opposite manner to the above.

[Problems to be Solved by the Invention] In the conventional storage opening/closing device as described above, the auxiliary storage chamber (7) is installed at the top of the storage (5), and the lid plate (8
) To open the cover plate (8), pull the bottom end of the cover plate (8) forward, rotate it upwards 90'', and then push it in to store it. ) is difficult to open and close.

This invention was made to solve the above-mentioned problems, and it is an object of the present invention to provide a storage opening/closing device that allows even a short user to easily open and close the cover plate of the auxiliary storage chamber.

[Means for Solving the Problems] The storage opening/closing device according to the present invention has a partition plate extending in the depth direction of the chamber, and support pins are provided at the top and bottom of one side of the lid plate provided on the front surface of the auxiliary storage chamber. is provided in a protruding manner and is fitted into the sliding groove to guide rotation and sliding of the support pin.

[Function] In this invention, support pins are provided protruding from the upper and lower sides of one side of the cover plate, and the support pins are inserted and guided into vertically opposing sliding grooves, so that the cover plate cannot be rotated in the horizontal direction. It is stored in a vertical position.

[Embodiment Figures 1 to 3 are diagrams showing an embodiment of the present invention.
The figure is a front view of the main part, Figure 2 is a sectional view taken along the line n-■ of Figure 1,
FIG. 3 is a perspective view of the main parts of FIG. 1, and the same parts as in the conventional device are designated by the same reference numerals.

In the figure, (8) is a cover plate provided at the front opening of the auxiliary storage chamber (7), and support pins (9) are attached to the upper and lower surfaces on the right side.
), (10) are provided protrudingly. (15) is a side partition plate that partitions the side surface of the auxiliary storage chamber (7), and the upper part thereof is bent into an L shape to form a support member (15a). (
Reference numeral 16) denotes a bottom partition plate that partitions the bottom of the auxiliary storage chamber (7), and a support member (16a) is provided in a part thereof at a position facing the support member (15a).

(F) and (18) are support members (15a) and (18), respectively.
Support pins (9) and (10) are fitted into the concave sliding grooves formed on the opposing surfaces of 16a), respectively.

In the storage opening/closing device configured as above,
When using the auxiliary storage chamber (7), pull the left end of the cover plate (8) forward as shown by arrow A in Figure 2, and rotate it 90'' counterclockwise when viewed from above.

If the support pins (9) and (10) are pushed in as shown by arrow B in the vertical position, the support members (15a) and (16a)
) is guided by the slides II (17) and (18) of the lid plate (
8) is stored along the side partition plate (15), and the auxiliary storage chamber (7) is opened. If the auxiliary storage chamber (7) is to be closed, the cover plate (8) can be pulled out and rotated by performing the reverse operation described above. Therefore, even a short user can easily open and close the cover plate (8).

In the above embodiment, the support pins (9) and (1) of the cover plate (8) are
0) and support members (15a) and (16a) are provided on the right side of the opening of the auxiliary storage chamber (7), but it is also possible to provide these on the left side and reverse the opening direction of the lid plate (8). It is.

FIG. 4 is a diagram corresponding to FIG. 3 showing another embodiment of the present invention.
A hole (18a) is provided in the bottom surface of the sliding groove (18) formed in the support member (16a) of the bottom partition plate (16).

In other words, moisture from food, etc. that accumulates in the sliding groove (18) is released from the hole (18a), and the moisture accumulated in the sliding groove (18) freezes and becomes trapped inside the sliding groove (18). This prevents interference with the operation of the support pin (10) that slides on the support pin (10).

[Effects of the Invention] As explained above, in this invention, concave sliding grooves are made to face each other on the top and bottom of the partition plate and extend in the depth direction of the auxiliary storage chamber, and are provided on the front surface of the auxiliary storage chamber. Support pins are provided protruding from the upper and lower surfaces of one side of the cover plate, and are fitted into the sliding grooves to guide rotation and sliding of the support pin, so the cover plate can be rotated horizontally. The lid can be moved and stored in a vertical position, making it easy for even short users to open and close the lid.
