First, FIG. 5 illustrates a position in which the dish shelf 100 is used, that is, a state in which a dish may be stored on the top surface 110a of the dish shelf 100. Such a position of the dish shelf 100 is named as being in the "storing position", "unfolding position" or "first position".

In detail, the frame coupling part 120 is coupled to the horizontal frame 51 so that the round part 121 surrounds the outer circumferential surface of the horizontal frame 51. At this time, the upper surface 110a is disposed to be inclined upward with respect to the ground, whereby the tableware may be stably stored in the upper surface 110a.

In addition, the guide part 130 is positioned to interfere with the vertical frame 53. In detail, the vertical frame 53 is formed with an interference portion 53a that interferes with the guide portion 130. The interference part 53a is formed at an upper end of the vertical frame 53, and is spaced apart by a predetermined distance below the horizontal frame 51. That is, the vertical frame 53 and the horizontal frame 51 adjacent to the vertical frame 53 are formed to be somewhat spaced apart.

The interference part 53a interferes (supports) the first stopper 135. By the interference between the interference part 53a and the first stopper 135, the dish shelf 100 may be supported at a position as shown in FIG. 5.

Next, FIG. 6 shows a position where the dish shelf 100 is not used, that is, the folded state of the dish shelf 100. As such, when the dish shelf 100 is not used, the folded state may be maintained, and thus the storage space of the first rack 50 may be efficiently utilized. The position of the dish shelf 100 as shown in FIG. 6 is referred to as being in the "folded position" or "second position".

The accommodating part 110 or the frame coupling part 120 may be supported by at least a portion of the frames 51 and 53 in a vertically oriented state, that is, arranged in parallel with the vertical frame 53.

In detail, the guide part 130 is provided with a second stopper 131a which interferes with the horizontal frame 51 in the folded state of the dish shelf 100. The second stopper 131a is understood as an inner side surface of the protrusion 131. The second stopper 131a may be supported above the horizontal frame 51.

At least a portion of the vertical frame 53 is in a state accommodated inside the guide hole 140. In the process of rotating or moving the dish shelf 100, the vertical frame 53 moves along the inside of the guide hole 140. In addition, the dish shelf 100 is guided by the vertical frame 53 and is eventually in the position as shown in FIG. 6.

The thickness w1 of the vertical frame 53 is formed to be somewhat smaller than the width w2 of the guide hole 140, thereby preventing the vertical frame 53 from interfering with the guide hole 140. And it can be moved smoothly inside the guide hole 140.

7 is a view showing the operation of the dish shelf according to an embodiment of the present invention. Referring to FIG. 7, a process in which the dish shelf 100 is switched from an open position to a folded position will be described.

In the state where the dish shelf 100 is in the open position, the round part 121 is coupled to an outer circumferential surface of the horizontal frame 51, and the first stopper 135 is an interference part of the vertical frame 53. It is in the state supported by 53a. Tableware may be stored on the upper surface 110a of the accommodating part 110.

If the use of the dish shelf 100 is not necessary, the position of the dish shelf 100 may be switched to the folded position.

In detail, the handle 150 may be moved downward while rotating the dish shelf 100 in a clockwise direction (as shown in FIG. 7).

If only the rotation of the dish shelf 100 is possible, the dish shelf 100 may interfere with the second rack 70. That is, a distance between the horizontal frame 51 to which the dish shelf 100 is coupled and the second rack 70 may be shorter than the length of the dish shelf 100.

However, the dish shelf 100 may slide downward along the vertical frame 53. In this process, the vertical frame 53 is accommodated in the guide hole 140, and the dish shelf 100 moves until the second stopper 131a interferes with the horizontal frame 51. Can be.

When the second stopper 131a interferes with the horizontal frame 51, the downward movement of the dish shelf 100 is stopped and fixed at the position as shown in FIG. 6. In addition, since one side surface (the left side surface of the horizontal frame in FIG. 7) of the horizontal frame 51 is supported by the guide part 130, the dish shelf 100 is separated from the horizontal frame 51. Can be prevented.

On the contrary, when the dish shelf 100 is to be used, the dish shelf 100 is moved upward by using the handle 150 in the counter as shown in FIG. 6 in the counterclockwise direction (see FIG. 7). Can be rotated.

The dish shelf 100 is rotated until the first stopper 135 interferes with the vertical frame 53, and when the first stopper 135 interferes with the vertical frame 53, FIG. 5. The position shown may be maintained.

As such, since the dish shelf 100 may be selectively rotated and moved depending on whether the dish is stored, the ease of use is increased, and the interference between the dish shelf 100 and the second rack 70 may be prevented. It works.
