Description

Technical Field

[0001] The present disclosure relates to a dish drying rack capable of expanding the storage area.

Background Art

[0002] Generally, in a kitchen, a drying rack for loading and drying dishes such as plates and bowls can be provided. The dish drying rack in the kitchen is mainly located on the top plate of the sink, and the washed dishes are loaded and dried.

[0003] The drying rack has a shelf structure with an open top, and when dishes are loaded, water and the like adhering to the dishes are discharged well. Such a drying rack is manufactured in a size suitable for installation on the top plate of the sink. Since the size of the drying rack placed on the top plate of the sink is limited, when there are many dishes to be stored or dried, there are restrictions in use. For this reason, conventionally, there have been many attempts to expand the size of the drying rack as needed.

[0004] However, the conventional drying rack has a structure in which an auxiliary shelf slidably installed on the main shelf is simply pulled out to the outside to expand the area, so it is insufficient for expanding the space. That is, the conventional structure only increases the area corresponding to the auxiliary shelf pulled out to the outside, and since the main shelf and the auxiliary shelf are still separated from each other, the effect of expanding the space cannot be expected.

[0005] Therefore, the conventional structure has a problem that the main shelf and the auxiliary shelf cannot be connected and widely expanded as one space for use. For this reason, even if the drying rack is expanded, large-sized dishes cannot be loaded, and there is a problem that the usability is reduced.

[0006] In recent years, various dishes have been developed and used, and the use of large-sized dishes has also increased. Therefore, improving the structure of the dish drying rack can provide many advantages to users.

Summary of the Invention

[0007] The objective of this project is to provide an expandable dish drying rack that can accommodate large dishes by connecting and expanding spaces, rather than simply increasing area.

[0008] The objective of this project is to provide an expandable dish drying rack that is easier to manufacture due to its simpler structure. [Means for solving the problem]

Modes for Carrying Out the Invention

[0026] The embodiments of the present invention will be described in detail below. However, these are presented as examples only and do not limit the present invention, which is defined only by the scope of the claims described later. The embodiments described later can be modified into various forms without departing from the concept and scope of the present invention. Parts that are identical or similar will be shown in the drawings using the same drawing number whenever possible.

[0027] The technical terms used herein are for the sole purpose of referring to specific embodiments and are not intended to limit the invention. The singular form used herein also includes plural forms unless the text explicitly indicates otherwise. The meaning of “includes” as used in this specification embodies a particular characteristic, domain, integer, stage, operation, element, and / or component, and does not exclude the existence or addition of other particular characteristics, domains, integers, stages, operations, elements, components, and / or groups.

[0028] Preferred embodiments of the present invention are described below with reference to the drawings. However, the following embodiments are merely preferred embodiments of the present invention, and the present invention is not limited to the following embodiments.

[0029] Figures 1 and 2 illustrate the configuration of the expandable dish drying rack according to this embodiment, and Figure 3 shows the use state of the expandable dish drying rack according to this embodiment.

[0030] For the sake of explanation, in Figure 1, the x-axis direction is defined as the lateral direction, and the surface facing the x-axis direction is referred to as the side or side of the drying rack. The z-axis direction is defined as the front-to-back direction, and the side from which the auxiliary shelf is pulled out along the z-axis direction is referred to as the front or front of the drying rack, and the opposite side as the rear or rear surface. The y-axis direction is defined as the up-and-down direction, and the upper side along the y-axis direction is referred to as the top or upper part, and the lower side as the bottom or lower part.

[0031] As illustrated, the drying rack 100 of this embodiment may include (1) a main shelf 200 on which dishes are placed and dried, (2) an auxiliary shelf 300 that is installed on the main shelf 200 so as to be movable horizontally and can be pulled out to the outside as needed, on which dishes are placed and dried, and (3) an upper shelf 400 that is installed on the top of the main shelf 200 so as to be removable and positioned away from the main shelf 200, on which dishes are placed and dried.

[0032] Hereinafter, "shelf" may refer to all of the main shelf 200, auxiliary shelf 300, and upper shelf 400.

[0033] In this way, the drying rack 100 can increase the stacking area for dishes by moving the auxiliary shelf 300 forward along the front-to-back direction from the main shelf 200, and can also increase the stacking area for dishes vertically by installing an upper shelf 400 above it.

[0034] Furthermore, the drying rack 100 in this embodiment has a structure in which the front of the main shelf 200 is completely open. As a result, when the auxiliary shelf 300 is pulled forward and moved, the space between the main shelf 200 and the auxiliary shelf 300 is not blocked, and they are connected as one unit, allowing the bottom surface to be expanded to its maximum extent. Therefore, large dishes can be easily loaded and dried on the bottom surface of the main shelf 200 and the auxiliary shelf 300, which are expanded and connected without interference.

[0035] The drying rack 100 may also include a water receiving plate 110 located below the main shelf 200, which collects and discharges water dripping from dishes. The water receiving plate 110 may be a plate structure formed to be approximately the same size as the bottom surface of the main shelf 200. The water receiving plate 110 has a structure in which the rear tip is bent downward to form a locking portion 112, and the peripheral edge is bent upward, and an outlet 114 can be formed in the center of the front tip from which the collected water is discharged. The bent rear locking portion 112 of the water receiving plate 110 can be hooked onto, for example, a horizontal bar 260 installed on the support legs 250 of the main shelf 200 and fixed in an inclined position. This allows water dripping from dishes stacked on the main shelf 200 to be collected and discharged towards the outlet 114 by the inclined water receiving plate 110.

[0036] Shelves 200, 300, and 400 are formed by a frame 500 that forms the skeleton and a plurality of support bars 600 installed at intervals between the frame 500, and may have a lower bottom surface, left and right sides extending in the front-to-back direction, and a front or rear surface extending in the left-to-right direction.

[0037] In the following description, the frame 500 and support bars 600 that form the skeleton of the drying rack 100, specifically the main shelf 200, auxiliary shelf 300, and upper shelf 400, will be distinguished by number. The term "frame 500" can refer to all of the frames distinguished by number, and the term "support bars 600" can refer to all of the support bars distinguished by number.

[0038] The frame 500 may consist, for example, of rigid bars with a relatively large diameter. The frame 500 is formed by bending the rigid bars at right angles and extending them vertically or horizontally to create the framework for each side of the shelf. The bent form and size of the frame 500 can be varied in various ways depending on the size of the drying rack 100, etc.

[0039] Multiple support bars 600 are installed at intervals along the skeletal frame 500 to form each face of the shelf. The support bars 600 may consist of bars with a relatively smaller diameter compared to the frame 500. The support bars 600 allow the dishes to be stably supported and prevent them from falling outwards.

[0040] The support bars 600 only need to be able to support and stably hold the dishes, and allow any moisture on the dishes to be easily drained to the outside. Their spacing and arrangement can be varied in many ways. For example, the support bars 600 can be arranged in one direction at regular intervals, or they can intersect at right angles to form a grid.

[0041] The main shelf 200 of this embodiment may include a main bottom portion 210 that forms the bottom surface, a main side portion 220 that forms the side surface, and a main rear portion 230 that forms the rear surface.

[0042] The main base 210 may include (1) a horizontally positioned rectangular frame-shaped first frame 510, and (2) a plurality of first support bars 610 that are joined to the first frame 510, spaced apart, and form the bottom surface of the main shelf 200.

[0043] The first frame 510 is a long bar, with both ends joined together to form a rectangular frame. A first support bar 610 is arranged on the first frame 510, extending in the front-to-back direction. Multiple first support bars 610 are arranged at intervals in the left-to-right direction and joined to the first frame 510 to form the bottom surface of the main shelf 200.

[0044] The main side section 220 may include a second frame 520 that is erected vertically on both sides along the left and right sides of the first frame 510 and is joined to and installed on the first frame 510.

[0045] The second frame 520 is a structure of long, extended bars, two of which form a pair and are positioned on both the left and right sides of the first frame 510. The second frame 520 is positioned perpendicular to the horizontally positioned first frame 510 and is joined to the left and right ends of the first frame 510, thereby forming the sides of the main shelf 200.

[0046] Both ends of the second frame 520 extend downward past the first frame 510, forming support legs 250 that support the main shelf 200 to the ground. As a result, the four support legs 250 formed by the second frame 520 can stably support the rectangular main shelf 200 to the ground.

[0047] The main rear section 230 may include (1) a third frame 530 that is spaced upward from the rear of the first frame 510, positioned horizontally, and joined between the left and right second frames 520, and (2) second support bars 620 that are joined between the third frame 530 and the first frame 510, positioned at intervals, and forming the rear surface of the main shelf 200.

[0048] The third frame 530 extends forward after both of its left and right ends bend at a right angle, and is installed by being joined to the second frame 520. The two ends of the third frame 530 that are joined to the left and right second frames 520 form support bars 722 to which the upper shelf 400 is attached. This will be explained later.

[0049] In this embodiment, both ends of the third frame 530, which is joined to and installed on the second frame 520, may have a structure that forms a support bar.

[0050] At the main rear section 230, a series of second support bars 620 are installed by extending vertically and joining them between the vertically separated first frame 510 and third frame 530, thereby forming the rear surface of the main shelf 200.

[0051] In this embodiment, the first support bar 610 may have a structure in which its rear end extends beyond the first frame 510 and is simultaneously bent upward before being joined to the third frame 530, thereby forming the second support bar 620. In other words, the first support bar 610 and the second support bar 620 are integrally connected to each other in a continuous manner.

[0052] With the aforementioned structure, the main shelf 200 takes the form of a rectangular container with an open top and sides and a rear. Dishes can be placed on the main bottom 210 of the main shelf 200 and stored stably for drying.

[0053] The front of the main shelf 200 may be an open structure. That is, at the front end of the first frame 510, no frame or support bar is installed on the upper part.

[0054] Thus, in this embodiment, the main shelf 200, by having its front open, expands the drying rack 100 and increases its area, and the expanded space is connected to create an expanded space. Therefore, not only a large number of dishes but also large dishes can be stored and stacked in the expanded space without interference.

[0055] The auxiliary shelf 300 is stored beneath the main bottom 210 of the main shelf 200 and can be pulled forward from the main shelf 200 for use as needed.

[0056] For this purpose, the auxiliary shelf 300 of this embodiment may include an auxiliary bottom portion 310 forming the bottom surface, an auxiliary side portion 320 forming the side surface, an auxiliary front portion 340 forming the front surface, and guide portions that allow the auxiliary shelf 300 to slide relative to the support legs 250 and the main shelf 200.

[0057] This allows the auxiliary shelf 300 to be slid along the guide section to be positioned below the bottom of the main shelf 200, or to be pulled forward from the main shelf 200 as needed and used as an auxiliary shelf 300.

[0058] The auxiliary bottom 310 may include (1) a front fourth frame 540 and a rear fourth frame 542 that are spaced apart in the front-rear direction and extend horizontally along the left-right direction to form a skeleton, and (2) a plurality of third support bars 630 that connect the front fourth frame 540 and the rear fourth frame 542 to form the bottom surface. The auxiliary bottom 310 is located below the main bottom 210 of the main shelf 200 and moves forward of the main shelf 200 along the front-rear direction.

[0059] The front fourth frame 540 and the rear fourth frame 542 are elongated bars, and the third support bar 630 is positioned between them, extending along the front-to-back direction. Multiple third support bars 630 are arranged at intervals along the left-to-right direction, and both ends are joined to the front fourth frame 540 and the rear fourth frame 542 to form the bottom surface of the auxiliary shelf 300.

[0060] The auxiliary front section 340 may include a fifth frame 550 positioned horizontally and spaced upward from the front fourth frame 540, and a fourth support bar 640 that is stretched and joined between the fifth frame 550 and the front fourth frame 540, and positioned at intervals to form the front of the auxiliary shelf 300.

[0061] The front surface of the auxiliary shelf 300 is formed by the fourth support bar 640 extending vertically and being joined between the fifth frame 550 and the front fourth frame 540, which are separated vertically at the auxiliary front section 340.

[0062] In this embodiment, the third support bar 630 may have a structure in which its front end extends beyond the front fourth frame 540, is bent upward, and is joined to the fifth frame 550 to form the fourth support bar 640. In other words, the third support bar 630 and the fourth support bar 640 are connected to each other in a continuous and integral manner.

[0063] The auxiliary side portion 320 may be formed by a sixth frame 560 that is integrally formed with the left and right ends of the fifth frame 550 and extends rearward along the front-rear direction. The sixth frame 560 is positioned above the third support bar 630 on the side of the auxiliary shelf 300, thereby forming the side of the auxiliary shelf 300.

[0064] As shown in Figure 2, the auxiliary side section 320 may further include an auxiliary bar 562 that is joined to and installed on the sixth frame 560 and positioned between the third support bar 630 and the sixth frame 560. The auxiliary bar 562 helps to minimize the detachment of dishes through the side of the auxiliary shelf 300.

[0065] The ends on both sides of the front fourth frame 540 bend at a right angle and extend downward to form auxiliary legs 350 that support and hold the auxiliary shelf 300 from the ground. This allows the front portion of the auxiliary shelf 300 to be stably supported from the ground by the auxiliary legs 350.

[0066] With the aforementioned structure, the auxiliary shelf 300 takes the form of a rectangular container with an open top and sides and a front. Dishes can be placed on the auxiliary bottom 310 of the auxiliary shelf 300, stored stably, and dried.

[0067] The rear of the auxiliary shelf 300 may be an open structure. That is, no frames or support bars are installed above the rear fourth frame 542.

[0068] Thus, in this embodiment, by having the rear of the auxiliary shelf 300 open, when the auxiliary shelf 300 is moved forward from the main shelf 200, the area of ​​the bottom of the drying rack 100 becomes wider by the amount of the bottom surface of the auxiliary shelf 300, and the bottom surface of the auxiliary shelf 300 is connected to the bottom surface of the main shelf 200, thereby achieving the effect of expanding the space. Therefore, not only a large number of dishes but also large dishes can be stored and stacked in the expanded space without interference.

[0069] The auxiliary shelf 300 is slidably connected to the main shelf 200 via a guide section.

[0070] In this embodiment, the guide portion may include (1) an upper projection 710 integrally formed at the tip of the sixth frame 560 of the auxiliary side portion 320 and projecting outward to the left and right; (2) a guide bar 712 that extends along the front-rear direction on the second frame 520 of the main shelf 200 at a position corresponding to the upper projection 710 and supports the upper projection 710 in a slidable manner; and (3) a lower projection 714 integrally formed at the tip of the rear fourth frame 542 of the auxiliary shelf 300, projecting outward to the left and right, and hooking onto the left and right front-rear extensions of the first frame 510 of the main shelf 200 and sliding.

[0071] Furthermore, the guide section may further include a guide bar 716 which is installed parallel to and spaced above the guide bar 712 to guide the upper part of the upper projection 710, so that the upper projection 710 moves along the space between the guide bar 712 and the guide bar 716.

[0072] As shown in Figures 2 and 3, upper protrusions 710 and lower protrusions 714 are integrally formed protruding from both ends of the sixth frame 560 and both ends of the rear fourth frame 542 of the auxiliary shelf 300, which are arranged vertically.

[0073] A guide bar 712 is horizontally installed on the main side portion 220 of the main shelf 200, aligned with the position of the upper projection 710. The upper projection 710 and lower projection 714 of the auxiliary shelf 300 are supported by being hooked onto the guide bar 712 of the main shelf 200 and the lateral end portion (the part extending in the front-to-back direction) of the first frame 510, respectively.

[0074] As a result, the auxiliary shelf 300 is stably supported by the upper protrusions 710 and lower protrusions 714 positioned above and below it, respectively, from the guide portion of the main shelf 200 and the first frame 510, and can be pulled out and slid more stably from the main shelf 200.

[0075] The upper projection 710 is integrally formed with the tip of the sixth frame 560. In this embodiment, the upper projection 710 can be formed by extending the left and right tips of the sixth frame 560 vertically upward and then bending them outward. The upper projection 710 may be formed to protrude to a sufficient length so that it can be hooked onto the upper guide bar 712.

[0076] In this way, by bending the tip of the sixth frame 560 to form an upper projection 710 that can be hooked onto the upper guide bar 712, the auxiliary shelf 300 can be connected to the main shelf 200 in a slidable manner in a structurally simpler manner.

[0077] The lower projection 714 is integrally formed at the left and right ends of the rear fourth frame 542. In this embodiment, the lower projection 714 can be formed by bending the ends of the vertical portions at the left and right ends of the rear fourth frame 542 outward to match the lateral end position of the first frame 510. The lower projection 714 may be formed to protrude to a sufficient length so that it can be placed over the lateral end of the first frame 510.

[0078] On the main side portion 220 of the main shelf 200, guide bars 712 and 716 are installed parallel to each other at a distance from each other, in positions corresponding to the upper projection 710, and the upper projection 710 is sandwiched and guided by them. This allows the upper projection 710 to move along the passage formed between the guide bars 716 and 712.

[0079] The distance between the guide bar 712 and the guide bar 716 can be set at a distance sufficient to allow the protruding portion to move smoothly without free movement.

[0080] Guide bar 712 supports the lower part of the upper projection 710, allowing it to slide. Guide bar 716 supports the upper part of the upper projection 710, preventing it from lifting upward. Guide bar 716 may be formed at a distance above guide bar 712.

[0081] Figure 3 shows the state in which the auxiliary shelf 300 is pulled out from the main shelf 200 according to this embodiment.

[0082] As shown in Figure 3, when the auxiliary shelf 300 is pulled outward relative to the main shelf 200, the auxiliary shelf 300 moves by sliding along the guide bar 712 and the first frame 510, with its upper projection 710 and lower projection 714 hooked onto the guide bar 712 and the first frame 510, respectively. Therefore, the auxiliary shelf 300 is pulled forward from the front of the main shelf 200 in the front-to-back direction while still connected to the main shelf 200.

[0083] The auxiliary legs 350, installed on the front side of the auxiliary shelf 300, support the front side of the auxiliary shelf 300 as it is extended. The rear end of the auxiliary shelf 300 is supported by the upper projection 710 and lower projection 714 hooking onto the guide bar 712 and the first frame 510 of the main shelf 200. As a result, when the auxiliary shelf 300 is fully extended from the main shelf 200, its front and rear sides are supported by the auxiliary legs 350 and the upper projection 710 and lower projection 714, respectively, allowing it to maintain a horizontal position.

[0084] As a result, the dish drying rack 100 in this embodiment can extend the auxiliary bottom 310 of the auxiliary shelf 300 outwards from under the main bottom 210 of the main shelf 200, thereby expanding the area on which dishes can be placed. Therefore, in addition to the main bottom 210 of the main shelf 200, more dishes can be additionally placed and dried through the auxiliary shelf 300.

[0085] Furthermore, since the front of the main shelf 200 and the rear of the auxiliary shelf 300 are not blocked from each other, the main bottom 210 of the main shelf 200 and the auxiliary bottom 310 of the auxiliary shelf 300 are connected at the same height. Therefore, large dishes can be stacked and dried in the space between the main bottom 210 of the main shelf 200 and the auxiliary bottom 310 of the auxiliary shelf 300, which are connected and expanded.

[0086] If the auxiliary shelf 300 is not needed, the area of ​​the drying rack 100 can be reduced by pushing the extended auxiliary shelf 300 into the interior of the main shelf 200, the opposite of the above case.

[0087] As the auxiliary shelf 300 is pushed and moved, the upper projection 710 and the lower projection 714 move along the guide bar 712 and the first frame 510, and are moved to the rear side of the main shelf 200. As a result, the auxiliary bottom 310 of the auxiliary shelf 300 moves below the main bottom 210 of the main shelf 200, and the auxiliary front 340 of the auxiliary shelf 300 is positioned on the main front of the main shelf 200, forming the front of the main shelf 200.

[0088] On the other hand, the drying rack 100 of this embodiment, by including an upper shelf 400, can expand the stacking area for dishes in the direction above the main shelf 200.

[0089] The upper shelf 400 in this embodiment may include an upper bottom portion 410 forming the bottom surface, an upper side portion 420 forming the side surface, and an upper rear portion 430 forming the rear surface.

[0090] The upper bottom section 410 may include (1) a horizontally positioned rectangular frame-shaped seventh frame 570, and (2) a plurality of fifth support bars 650 that are joined to the seventh frame 570 and spaced apart to form the bottom surface of the main shelf 200.

[0091] The seventh frame 570 is a long bar, with both ends joined together to form a rectangular frame. The fifth support bar 650 is arranged on the seventh frame 570 so that it extends long in the front-to-back direction. Multiple fifth support bars 650 are arranged at intervals along the left-to-right (lateral) direction and joined to the seventh frame 570 to form the bottom surface of the upper shelf 400.

[0092] The upper side section 420 may include an eighth frame 580 that is erected vertically on both the left and right sides along the left and right sides of the seventh frame 570 and is joined to the seventh frame 570.

[0093] The eighth frame 580 is a long, extended bar structure, with both ends joined together to form a rectangular frame. Two eighth frames 580 form a pair and are positioned on both the left and right sides of the first frame 510. The eighth frame 580 is positioned perpendicular to the horizontally positioned first frame 510 and joined to the left and right (lateral) ends of the seventh frame 570, thereby forming the sides of the upper shelf 400.

[0094] The lower end of the eighth frame 580 extends downward past the seventh frame 570 and connects to the side of the main shelf 200.

[0095] The upper rear section 430 may include (1) a ninth frame 590 that is horizontally positioned at an upward distance from the rear of the seventh frame 570 and joined and installed between the left and right eighth frames 580, and (2) a series of sixth support bars 660 that are joined and installed between the ninth frame 590 and the seventh frame 570, spaced apart to form the rear surface of the main shelf 200.

[0096] The ninth frame 590 extends forward with both ends bent at a right angle and is joined to the eighth frame 580. The sixth support bar 660 extends vertically and is joined to the space between the seventh frame 570 and the ninth frame 590, which are separated vertically at the upper rear section 430, thereby forming the rear surface of the upper shelf 400.

[0097] In this embodiment, the fifth support bar 650 may have a structure in which its rear end extends beyond the seventh frame 570, is bent upward, and is joined to the ninth frame 590 to form the sixth support bar 660. In other words, the fifth support bar 650 and the sixth support bar 660 are connected by being integrally continuous.

[0098] With the aforementioned structure, the upper shelf 400 takes the form of a rectangular container with an open top and left and right sides and a rear surface. Dishes can be placed on the upper bottom 410 of the upper shelf 400 and stored stably for drying.

[0099] The upper shelf 400 is stacked above the main shelf 200 by connecting the lower end of the eighth frame 580 to the top of both sides of the main shelf 200. This allows dishes to be stacked in multiple layers on the main shelf 200 and on the upper shelf 400 above it.

[0100] As shown in Figures 1-2 and 4, the fixing part is provided at the lower end of the eighth frame 580, and detachably connects the eighth frame 580 to the main side portion 220 of the main shelf 200.

[0101] The fixing portion of this embodiment, as shown in Figure 4, may include (1) an inclined portion 720 extending outward from the lower end of the eighth frame 580, (2) a support bar 722 horizontally installed on the second frame 520 of the main shelf 200 to support the inclined portion 720 from below, and (3) a locking bar 724 horizontally installed on the eighth frame 580 above the inclined portion 720 and locked onto the second frame 520.

[0102] The inclined portion 720 is formed to protrude outward from the eighth frame 580 along the lateral direction. A locking bar 724 is installed horizontally above the inclined portion 720 at a predetermined distance. A support bar 722 is installed horizontally from the upper end of the second frame 520, which forms the main side portion 220 of the main shelf 200, at a predetermined distance downward.

[0103] In this embodiment, the left and right ends of the third frame 530, which is joined and installed to the second frame 520, may have a structure that forms support bars 722.

[0104] The distance between the lower end of the inclined portion 720 formed on the eighth frame 580 and the locking bar 724 corresponds to the distance between the upper end of the second frame 520, which forms the upper end of the main side portion 220 of the main shelf 200, and the support bar 722.

[0105] As a result, as shown in Figure 4, when the lower end of the eighth frame 580 is connected to the upper end of the main side portion 220 of the main shelf 200, the inclined portion 720 is sandwiched between the upper end of the second frame 520 and the support bar 722 and hooked onto the support bar 722, while the locking bar 724 of the eighth frame 580 is hooked onto the upper end of the second frame 520 of the main side portion 220.

[0106] The load of the upper shelf 400 is applied to the inclined section 720 through the eighth frame 580, causing the inclined section 720, supported by the support bar 722, to be pushed outward relative to the support base (the upper end of the main side section 220). As a result, the locking bar 724 installed on the eighth frame 580 locks to the upper end of the second frame 520 of the main side section 220, and the eighth frame 580 is supported by the upper end of the second frame 520 without descending any further.

[0107] Since the inclined section 720 is supported by the support bar 722 on its inclined surface, a force pushing it outward due to the load of the upper shelf 400 continuously acts on it. Therefore, the lower end of the inclined section 720 does not move inward over the support bar 722 and is not separated from the main side 220 of the main shelf 200. This allows the eighth frame 580 of the upper shelf 400 to remain connected to the main side 220 of the main shelf 200.

[0108] Conversely, when an upward force is applied to lift the upper shelf 400, the inclined section 720 separates above the support bar 722 and comes out from the upper end of the second frame 520, allowing the upper shelf 400 to be easily separated from the main shelf 200.

[0109] As described above, exemplary embodiments of the present invention have been illustrated and explained, but various modifications and other embodiments may be made by skilled technicians in the art. Since all such modifications and other embodiments are considered and included in the appended claims, they do not depart from the true spirit and scope of the present invention.
