1 to 12, a drawer 10 according to the present invention includes a main frame 100, an upper frame 200, and a drawer 300.

First, the main frame 100 has a cube shape or a rectangular parallelepiped shape in which the front and the top are opened so as to be continuously arranged along the lamination and lateral sides in multiple stages.

The main frame 100 may be made of synthetic resin, metal, or the like, and a mounting space 110 may be formed in the main frame 100.

The mounting space 110 is opened frontward so that a drawer 300 to be described later can be coupled and the upper frame 200 to be described later is horizontally coupled to the upper portion of the mounting space 110.

A first protrusion 120 protrudes upward from the upper end of the main frame 100 and at least one engaging groove 130 horizontally extends along a side of the first protrusion 120.

The first protrusion 120 protrudes from the upper end of the main frame 100 by a predetermined length as shown in FIGS. 1, 3 and 4. The first protrusion 120 is formed at an upper end of the first protrusion 120, 200 are seated.

Here, the first protrusion 120 is formed to have a length along the edge of the main frame 100, as shown in FIG.

The first protrusions 120 may protrude vertically and the first protrusions 120 may be formed in the left and right directions of the main frame 100.

Alternatively, the first protrusions 120 may be formed in the left and right direction and the rear direction of the main frame 100, respectively.

The outer surface of the first protrusion 120 is spaced apart from the upper edge of the main frame 100 and a gap is formed between the outer surface of the first protrusion 120 and the upper edge of the main frame 100. [ A step 121 having a width is formed.

The step 121 may be formed horizontally and the upper surface of the step 121 is seated in a shape corresponding to the lower end of the second protrusion 210 described later.

The latching groove 130 is formed in the first protrusion 120 and corresponds to the latching protrusion 220 of the upper frame 200 to be described later.

The latching groove 130 may be formed in at least one direction along the longitudinal direction of the first protrusion 120 and horizontally through the inner and outer surfaces of the first protrusion 120.

The engaging groove 130 may have a length in the longitudinal direction of the first protrusion 120, but the shape of the engaging groove 130 may be variously applied.

If the upper frame 200 is to be separated, the lower end of the second protrusion 210 may be opened outward to separate the engaging protrusion 220 from the engaging groove 130. [ .

In addition, a lower assembly block 140 for coupling with the upper assembly blocks 230 to be described later is protruded downward from the lower surface of the main frame 100.

The lower assembly block 140 is staggeredly coupled to an interval between the upper assembly blocks 230 to be described later so that the lower assembly block 140 is protruded downward so as to be in close contact with the upper assembly blocks 230 .

The lower assembly block 140 is staggered at a gap between upper assembly blocks 230 to be described later so that a side surface of the lower assembly block 140 is in close contact with a side surface of the upper assembly blocks 230.

For this, the lower assembly block 140 may vary depending on the shape and arrangement of upper cooking blocks 230, which will be described later, and the lower assembly block 140 may be formed in a space between upper assembly blocks 230 And has a corresponding shape to be inserted.

In particular, a plurality of contact surfaces 141 may be concavely formed on the side surfaces of the lower assembly blocks 140 such that side surfaces of the upper assembly blocks 230 to be described later are closely contacted.

Since the contact surfaces 141 are in close contact with the side surfaces of the upper assembly blocks 230, they can be closely contacted with the side surfaces of the upper assembly blocks 230 in a wide area.

For example, when the upper assembly block 230 is applied in a cylindrical shape as shown in FIGS. 7 to 9, the contact surfaces 141 may be formed in a concave curved surface shape.

On the other hand, when the upper assembly block 230 is applied in a rectangular shape or a rectangular shape as shown in FIG. 10, the contact surfaces 141 may be formed in a concave polygonal shape.

As described above, the close contact surface 141 can be applied in various forms according to the shape of the upper assembly block 230. The close contact surface 141 is in close contact with the upper assembly block 230 to be described later, .

A plurality of support blocks 150 may be further coupled to the bottom of the main frame 100 as shown in FIGS. 3 to 5, and a lower end of the support block 150 is supported on the ground.

For this purpose, an installation groove may be recessed on the bottom side of the main frame 100, and an upper end of the support block 150 may be inserted corresponding to the installation groove.

The lower end of the support block 150 is protruded to the lower side of the main frame 100 and is seated on the ground. At this time, the lower surface of the main frame 100 is spaced apart from the ground.

For example, when the drawer 10 of the present invention is stacked in multiple stages, the supporting block 150 can be coupled only to the bottom surface of the main frame 100 positioned at the lowermost layer.

The upper frame 200 is coupled to the upper end of the main frame 100 and the upper frame 200 is coupled to the upper end of the main frame 100 to form the upper surface of the mounting space 110.

Here, a second protrusion 210 for intersecting with the first protrusion 120 is protruded downward from the bottom of the upper frame 200.

The second protrusions 210 are formed continuously along the rim of the upper frame 200 to form a frame for covering the outer surface of the first protrusions 120.

For example, when the upper frame 200 is horizontally coupled to the upper end of the main frame 100, the second protrusions 210 are cross-coupled to surround the outer surface of the first protrusions 120.

At this time, the inner surface of the second protrusion 210 is in close contact with the outer surface of the first protrusion 120, and the lower end of the second protrusion 210 is horizontally mounted on the upper surface of the step 121.

The outer surface of the second protrusion 210 may be coplanar with the outer surface of the main frame 100 to form the same plane.

At least one locking protrusion 220 horizontally protrudes along the inner surface of the second protrusion 210 and the locking protrusion 220 is inserted into the locking recess 130.

When the upper frame 200 is coupled to the upper end of the main frame 100, the locking protrusion 220 is horizontally inserted through the outer opening of the locking groove 130.

Since the locking protrusion 220 is horizontally inserted into the locking groove 130, the upper frame 200 coupled to the main frame 100 is prevented from being separated upward.

In addition, the guide surface 221 may be inclined so that the upper and lower widths gradually decrease toward the center of the upper frame 200 on the lower surface or the upper surface of the locking protrusion 220.

The guide surface 221 is slid in a state in which the guide surface 221 is in close contact with the inner circumferential surface of the engaging groove 130 when the engaging protrusion 220 is inserted through the entrance of the engaging groove 130.

Further, since the front end of the locking protrusion 220 is formed to have a narrow width by the guide surface 221, the front end of the locking protrusion 220 can be easily inserted into the locking groove 130.

Alternatively, the cutout groove 220 may be formed horizontally so as to be opened forward as shown in FIG.

The cutout groove 222 may divide the front end of the engagement protrusion 220 into two or more portions and the engagement end 223 may be formed with a larger diameter at the edge of the protruded end of the engagement protrusion 220 .

The engaging end 223 may have a gradually decreasing diameter toward the protruding end of the engaging protrusion 220.

For example, when the front end of the locking protrusion 220 is inserted into the locking groove 130, the locking end 223 is slid in a state of being in close contact with the inner circumferential surface of the locking groove 130, Is deformed to the position of the cutting groove 222. [

Thereafter, when the insertion of the locking protrusion 220 is completed, the locking groove 222 is restored to its original width by the elastic restoring force of the locking protrusion 220.

At this time, since the engaging end 223 is engaged with the inner circumferential surface of the first protrusion 120 by the elastic restoring force of the engaging protrusion 220, the engaging protrusion 220 is not separated in the direction opposite to the inserting direction.

Therefore, since the front end of the locking protrusion 220 inserted into the locking groove 130 is engaged, the coupling force between the locking protrusion 220 and the locking groove 130 can be further improved.

In addition, the lower end of the second locking protrusion 220 and the upper surface of the step 121 can be mated as shown in FIG.

In this case, an auxiliary coupling protrusion 211 may protrude downward from the lower end of the second locking protrusion 220, and the auxiliary coupling protrusion 211 may be correspondingly inserted into the upper surface of the step 121 The auxiliary engaging groove 122 may be concave downward.

By further forming the auxiliary coupling protrusions 211 and the auxiliary coupling grooves 122 in this way, the coupling force between the main frame 100 and the upper frame 200 can be further improved.

A plurality of upper assembly blocks 230 spaced apart from each other are protruded upward from the upper surface of the upper frame 200.

The upper assembly block 230 is spaced apart from the upper assembly block 230. The upper assembly block 230 may be formed in a cylindrical shape so that a circumferential surface is formed on the side surface.

Here, the upper projecting surfaces of the upper assembly blocks 230 may be formed horizontally so as to be in close contact with the lower surface of the main frame 100 to be described later.

Alternatively, the upper assembly block 230 may be protruded in a polygonal (rectangular or square) shape so as to form a polygonal side surface.

In the upper assembly block 230, at least one group A is formed with two or more of them separated from each other.

For example, when four upper assembly blocks 230 are used, two of the four upper assembly blocks 230 are arranged side by side on the front side in the left-right direction with respect to the center of the main frame 100 And the remaining two can be arranged in parallel in the left-right direction of the rear side.

In this case, two upper assembling blocks 230 of the four upper assembling blocks 230 are arranged in the left-right direction in front of the center of the main frame 100, and the remaining two upper assembling blocks 230 230 may be arranged in parallel in the left-right direction of the rear side with respect to the center of the upper frame 200.

The upper assembly blocks 230 may be formed to have the same spacing between the front and rear sides, but the gap between the upper assembly blocks 230 may be variously applied.

Meanwhile, the upper assembly block 230 may be disposed (not shown) so that two or three of the upper assembly blocks 230 are spaced apart from each other to form at least one or more groups.

For example, when four upper assembly blocks 230 are formed as one group A on the upper surface of the upper frame 200, as shown in FIG. 7, Can be formed in four directions.

In this case, since the upper assembly blocks 230 are closely attached to the four contact surfaces 141, the multi-layered main frame 100 and the upper frame 200 are assembled without shaking.

Alternatively, when eight upper assembly blocks 230 are formed by two groups A and B on the upper surface of the upper frame 200, as shown in FIG. 8, the lower assembly block 140 It can be formed in two.

In this case, the upper assembly blocks 230 forming the two groups A and B may be in close contact with the contact surfaces 141 of the lower assembly blocks 140, respectively.

In another embodiment, when eight upper assembly blocks 230 are formed by two groups A and B on the upper surface of the upper frame 200, as shown in FIG. 9, The number of the contact surfaces 141 may be eight.

In another embodiment, when three upper assembly blocks 230 are formed on the upper surface of the upper frame 200, the contact surface 141 of the lower assembly block 140 may be formed in three directions.

The drawer panel 10 of the present invention may be stacked in a zigzag shape along the oblique direction as well as in a vertically stacked form as shown in Figs. 11 and 12.

In this case, it is also possible to stack a plurality of drawer boxes 10 in parallel to each other on the floor surface, and to stack another drawer box 10 between the drawer boxes 10 arranged on the floor surface.

The drawer 300 is coupled to the drawer 300 through a front space of the mounting space 110 of the main frame 100. The drawer 300 has a storage space 310 opened upward.

A handle 320 is formed on the front surface of the drawer 300 so that the user can grip the handle 320. The shape of the handle 320 can be variously applied.

Rollers 330 that can be rolled in the forward and backward directions can be installed on both sides of the drawer 300 in a state of being mounted on the bottom surface of the mounting space 110.

To this end, an installation groove (not shown) for engaging the rotation axis of the rollers 330 may be formed concavely on the lower surface of the drawer 300 in the right and left direction.

That is, when the drawer 300 is coupled to the mounting space 110, the lower ends of the rollers 330 are seated on the bottom surface of the mounting space 110. When the drawers 300 are moved back and forth, The drawer 300 is moved.

As a result, according to the present invention, the upper plate 200 having the assembly block structure formed on the upper portion of the main frame 100 is detachably coupled to the main frame 100 to secure the main frame 100 and the upper frame 200 firmly The upper frame 200 can be replaced. Accordingly, various types of assembly blocks can be selected, and a variety of uses can be ensured.

In addition, the present invention can form an assembly block structure corresponding to the main frame 100 and the upper frame 200 so as to be stacked in multiple stages, thereby preventing positional change due to external force during stacking in multiple stages, It can be extended to several layers, ensuring diversity of use, and can be stacked with oblique lines or zigzag, so it is easy to produce a decorative figure and use space.
