As shown in these figures, the main shelf plate 20 is installed horizontally inside the storage space of the refrigerator body serves to partition the storage space. On the upper surface of the main shelf plate 20 is stored. The main shelf plate 20 is preferably formed of a transparent material together with the support cut 22 to be described below.

 Support cuts 22 are provided on the lower surface of the main shelf board 20 at predetermined intervals. The support cut 22 is formed long in the front-rear direction of the main shelf plate 20. In the present embodiment, the support cut 22 is shown as being provided on the main shelf plate 20, the support cut 22 may be provided on the ceiling of the storage space. Therefore, it can be said that the support cut 22 is provided on the ceiling of a predetermined storage space (including a unit storage space partitioned by a shelf).

As illustrated in FIG. 5, the support cut 22 is formed with first and second guide slots 24 and 24 ′ that are elongated in the front and rear directions, respectively. The length of the guide slot (24, 24 ') is a support link to be described below when the secondary shelf plate 30 to be described below is seated on the lower surface of the main shelf plate 20 and moved to the use position It is equal to the distance that the penetrating portion 43 of the 40 moves. The distance W between the first and second guide slots 24 and 24 'must be equal to the length of the support guide portion 42 of the support link 40 to be described below.

A guide rib 26 is elongated along the leading edge upper edge of the guide slots 24 and 24 '. The guide rib 26 protrudes from the support cut 22 vertically by a predetermined width along the guide slots 24 and 24 ′. The guide rib 26 guides the support guide portion 42 of the support link 40 to be described below when the auxiliary shelf plate 30 is drawn out or received. To this end, the guide rib 26 is formed to extend toward the tip end of the support cut 22 more than the tip ends of the guide slots 24 and 24 '.

A support rib 28 is formed long along the lower edge of the rear end side of the guide slots 24 and 24 '. The support rib 28 is configured in the same shape as the guide rib 26. The support rib 28 serves to support the support guide portion 42 of the support link 40 in a state in which the auxiliary shelf plate 30 is accommodated on the lower surface of the main shelf plate 20. To this end, the support ribs 28 are preferably formed almost all over the lower edges of the guide slots 24 and 42 '. For reference, the guide ribs 26 and the support ribs 28 are formed along the upper and lower portions of the guide slots 24 and 24 ', respectively, and are formed side by side in the middle portions of the guide slots 24 and 24'. .

A stopper 29 is formed on the inner surface of the front end of the support cut 22 corresponding to the front end of the first guide slot 24 so as to face each other on the support cuts 22 on both sides. The stopper 29 prevents the support guide portion 42 of the support link 40, which will be described below, from being arbitrarily rotated forward of the support cut 22. Of course, since the support link 40 and the support cut 22 and the like are injection moldings and have a certain degree of elasticity, when a predetermined force or more is applied, the support guide portion 42 of the support link 40 is the stopper 29. ) Can be crossed.

The auxiliary shelf board 30 is formed in a substantially rectangular plate shape. The auxiliary shelf 30 is accommodated on the lower surface of the main shelf plate 20 or the ceiling of the storage space, or selectively moved to a position below a predetermined distance from the lower surface of the main shelf plate 20 or the ceiling surface of the storage space. Is installed. The secondary shelf plate 30 is stored by mounting the storage on the upper surface at the position moved to the lower surface of the main shelf plate 20 below a predetermined distance.

Link hanger 32 is provided on the lower surface of the secondary shelf plate (30). The link hanger 32 is formed in a ring-shaped one side of the opening, one side of the connection portion 41 of the support link 40 to be described below is rotatably inserted. When viewed from the front of the auxiliary shelf plate 30, the link hook mechanism 32 is a total of four are formed on the front and rear ends, one each on the left and right sides. The front end of the link hook 32 is formed adjacent to the front end of the auxiliary shelf plate 30, the rear end is spaced apart from the rear end by the length of the support guide portion 42 of the support link 40 to be described below. Formed in a closed position.

The opened portion of the link hook 32 is opened at a position rotated by a predetermined angle from the bottom of the lower surface of the auxiliary shelf plate 30 to the rear. In this case, the opened position is preferably a position rotated about 45 ° to the rear of the auxiliary shelf plate 30 directly under the auxiliary shelf plate 30.

A plurality of communication holes 34 are drilled in the auxiliary shelf plate 30. The communication hole 34 allows the cold air of the storage space to flow between the upper and lower portions of the auxiliary shelf plate 30.

The support link 40 serves to support the secondary shelf plate 30. The support link 40 is provided with a connection portion 41 having a length slightly shorter than the width between both ends of the secondary shelf plate (30). The connection part 41 is positioned on the lower surface of the auxiliary shelf plate 30 to support the auxiliary shelf plate 30. Support guides 42 are provided at both ends of the connection part 41 to be perpendicular to the extending direction of the connection part 41, respectively. The support guide portion 42 is guided to the guide ribs 26 and is supported by the support ribs 28 so that the auxiliary shelf plate 30 can be easily drawn out and stored.

At the tip of the support guide portion 42, as shown in FIG. 6, a through portion 43 penetrating the guide slots 24 and 24 'is provided. The through part 43 extends outwardly from both ends of the support link 40, and extends in the same direction as the extending direction of the connection part 41. The through part 43 is formed to a relatively short length.

The connection part 41 is provided with a flow preventing rib 45 in a position corresponding to the link hook 32 provided on the lower surface of the auxiliary shelf plate (30). The flow preventing ribs 45 are formed in pairs at positions corresponding to the link hook holes 32, respectively. The flow preventing ribs 45 are positioned at both ends of the link hook hole 32 while the connecting portion 41 is fitted to the link hook hole 32 to support the support link 40 and the auxiliary shelf plate. Prevent relative movement between the 30.

Inserting hooks 47 are respectively provided at the front end of the through part 43. The insertion hook 47 is provided with one pair in each of the through-holes 43, there is a predetermined interval between them, the insertion hook 47 can be elastically deformed by the interval. The insertion hook 47 prevents the penetrating portion 43 from being arbitrarily removed while being inserted into the guide slots 24 and 24 ', and also into the insertion hole 54 of the linkage link 50 to be described below. It is inserted so that it does not come out arbitrarily.

The interlock link 50 connects the through portions 43 of the corresponding ends of the pair of support links 40 to each other so that the support links 40 can be rotated at the same time. The interlocking link 50 is fastened to be relatively rotatable to the penetrating portion 43 of the support link 40 at the outer side of each support cut 22.

At both ends of the interlocking link 50, as shown in FIG. 7, a connection opening ring 52 having an insertion hole 54 into which the through portion 43 of the support link 40 is inserted is provided. do. The connection opening ring 52 has an opening 55 formed at one side thereof so that the insertion hole 54 communicates with each other. One side of the opening 55 formed in the connection opening ring 52 is opened in the direction of gravity in the state of being assembled to the support link 40. The other side of the opening 55 formed in the connection opening ring 52 is formed to open in the direction opposite to gravity.

However, the connection opening ring 52 in which the opening 55 is formed in the opposite direction of gravity has an opening 55 formed at a position rotated about 45 ° in the end direction of the linkage link 50 in the opposite direction of gravity. desirable. The difference in the position of the opening 55 of the connection opening ring 52 provided at both ends of the linkage link 50 as described above is to prevent the linkage 50 from being removed at any time.

Here, the distance between the center of the insertion hole 54 at both ends of the linkage link 50 is formed slightly larger than the distance between the center of the link hook mechanism 32 when viewed from the side. This is because the interlocking link 50, the support guide portion 42 of the two support links 40, and the auxiliary shelf plate 30 do not become a rectangular four-section link during the rotation operation of the auxiliary shelf plate 30. In other words, it is designed to be a four-section link of an inverted trapezoidal shape so that the characteristics of the rotational motion are kept constant.

Hereinafter, the operation of the auxiliary shelf assembly of the refrigerator according to the present invention having the configuration as described above in detail.

8 is sequentially shown that the auxiliary shelf assembly of the embodiment of the present invention is operated. First, FIG. 8A illustrates a state in which the auxiliary shelf plate 30 is spaced apart from the lower surface of the main shelf plate 20 and lowered downward. In such a state, the storage may be seated on the auxiliary shelf plate 30.

In FIG. 8A, the support guide portion 42 of the support link 40 is caught by the stopper 29 and does not protrude forward. That is, the support guide portion 42 of the support link 40 is caught by the stopper 29 so that the auxiliary shelf plate 30 does not protrude forward arbitrarily. However, when pulling the auxiliary shelf plate 30 with a predetermined force or more, the support guide portion 42 of the support link 40 passes over the stopper 29. This is a case for accommodating the auxiliary shelf plate 30.

Now, the storage of the auxiliary shelf 30 in the lower surface of the main shelf 20 in the state of Figure 8a will be described. When holding and pulling the front end of the auxiliary shelf plate 30, the auxiliary shelf plate 30 is rotated in the direction of the arrow of Figure 5a around the through portion 43 of the support link 40. Of course, the connection portion 41 of the support link 40 and the auxiliary shelf plate 30 (link hook hole 32) is also relatively rotated.

The secondary shelf plate 30 is rotated until the support guide portion 42 of the support link 40 is guided in parallel with the guide rib 26. That is, the auxiliary shelf plate 30 is rotated until the state shown in FIG. 8B is reached. At this time, the through part 43 of the support link 40 is located at the top of the guide slots 24 and 24 ', respectively.

Next, the auxiliary shelf 30 is pushed in the direction of the arrow of FIG. 8B. In this case, the through part 43 of the support link 40 is moved along the first and second guide slots 24 and 24 '. At this time, the support guide portion 42 is guided by the guide ribs 26 and the support ribs 28.

A state in which the auxiliary shelf plate 30 is completely pushed in is shown in FIG. 8C. Here, it can be seen that the support guide portion 42 of the support link 40 is supported by the support rib 28. The through portion 43 of the support link 40 is located at the rear end of the guide slots 24 and 24 '. In this case, since the support ribs 28 are formed over almost the entire lower portion of the guide slots 24 and 24 ′, the support ribs 28 may support most of the support guide portions 42. In addition, since the support guide portion 42 is located between the support rib 28 and the guide rib 26, the support guide portion 42 of the support link 40, that is, the auxiliary shelf plate 30 ) Does not rotate arbitrarily.

In this case, the upper surface of the auxiliary shelf plate 30 is in a state closest to the lower surface of the main shelf plate 20. This can be seen well in FIGS. 3 and 4. In this state, it is possible to store a relatively high storage on the separate main shelf plate 20 in the lower portion of the secondary shelf plate (30).

The auxiliary shelf plate 30 is pulled forward once in order to lower the secondary shelf plate 30 and to store the storage thereon, and the through portion 43 of the support link 40 is guide slots 24 and 24 '. To be moved from the rear end to the end.

When the through part 43 is positioned at the tip of the guide slots 24 and 24 ′, the support guide part 42 of the support link 40 is completely released from the support rib 28. Therefore, the auxiliary shelf plate 20 is lowered in the direction of gravity by the weight of the auxiliary shelf plate 20 and the support link 40.

On the other hand, in the present invention, the flow preventing rib 45 formed in the connection portion 41 of the support link 40 is located at both ends of the link hook 32 of the auxiliary shelf plate 30, the auxiliary shelf plate 30 It does not flow left and right with respect to the support link 40.

In addition, the linkage link 50 is in the direction of the opening 55 of one of the connecting opening 52 in the direction of gravity, the other is in a position rotated by a predetermined angle in the direction opposite to gravity. Accordingly, the coupling opening 52 having the opening 55 rotated by a predetermined angle in the opposite direction of gravity is engaged with the penetrating portion 43 of the one support link 40, and the opening 55 is formed in the gravity direction. Connection opening ring 52 may be coupled to the through portion 43 of the other support link (40).

The rights of the present invention are not limited to the embodiments described above, but are defined by the claims, and those skilled in the art can make various modifications and adaptations within the scope of the claims. It is self-evident.

For example, two or more support links may be used depending on the length of the auxiliary shelf board. This is to ensure a stable support when the storage is seated on the secondary shelf.

In addition, two or more link links formed on the bottom surface of the auxiliary shelf may be formed according to the size of the auxiliary shelf. However, the flow preventing rib is not necessarily formed to correspond to each connection link.

In the present invention as described above in detail can be expected the following effects.

First, in the present invention, since the auxiliary shelf plate is supported by the support link that moves both ends along the guide slot, the front and rear widths of the main shelf plate and the auxiliary shelf plate may be the same. Thus, the storage space inside the refrigerator can be used more efficiently.

In the present invention, the auxiliary shelf plate is supported to be received and withdrawn by a link mechanism that is integrally connected to the support link and the interlocking link, and one side of the support link is supported by a stopper formed on the support cut so that the secondary shelf plate is not arbitrarily flown. Do not Therefore, the configuration in which the auxiliary shelf plate does not flow in the state where the auxiliary shelf assembly is used is simplified, and thus the manufacturing and assembly of the auxiliary shelf assembly is simplified, and the auxiliary shelf plate does not arbitrarily flow in the state where the storage is stored.

Next, in the present invention, since the support links for supporting the auxiliary shelf plate are connected to each other by an interlocking link to operate integrally, the operation reliability of the auxiliary shelf plate is increased, and the length of the linkage link is slightly longer than the distance between the connection portions of the support link. Therefore, there is an effect that a dead point does not occur during the rotation operation of the auxiliary shelf plate.

In addition, in the present invention, the support link for the storage, withdrawal and support of the auxiliary shelf plate is connected to each other by an interlocking link, so that the support link, the interlocking link and the auxiliary shelf plate form a link mechanism connected to each other, so that the storage of the auxiliary shelf plate and There is an effect that the withdrawal operation is performed constantly.

In the present invention, since the opening direction formed in the connection opening ring of the interlocking link is at a position rotated by a predetermined angle in the direction opposite to gravity and the other side, the assembling work of the interlocking link is easy, and once assembled The interlock link is not detached from the support link arbitrarily, thereby making the assembly of the auxiliary shelf assembly firm.
