1 to 12 , the prefabricated furniture 10 according to an embodiment of the present invention includes a frame 20 , an assembly unit 100 , a shelf 30 , and a fixed support unit 200 .

The frame 20 forms a frame (outer shape) of the furniture. In particular, the frame 20 is formed by arranging a plurality of connecting beams 22 in various shapes such as a circle and a polygon on a plane. In addition, the frame 20 is formed so that a plurality of connecting beams 22 are arranged in one or more layers in the longitudinal direction. Of course, the frame 20 can be deformed into various shapes, and the connecting beam 22 can be applied with various shapes and various materials in cross-section. For convenience, the connecting beam 22 is shown as having a rectangular shape.

In addition, the assembly unit 100 serves to guide the assembly by connecting the adjacent connecting beams 22 to form the frame 20 . At this time, as the connecting beam 22 is freely extendable by the assembly unit 100 , the prefabricated furniture 10 according to the present invention can be easily assembled and expanded.

In addition, the shelf 30 is connected to the connecting beam that is connected and assembled to each other on the same plane by the assembly unit 100 . Accordingly, in the prefabricated furniture 10 according to the present invention, a storage space is formed.

The fixing support 200 serves to connect and fix the shelf 30 to the connecting beam 22 corresponding to the fitting type.

In detail, the assembly unit 100 includes a connection connector 110 for connecting and connecting a plurality of connecting beams 22 . The connecting connector 110 serves as a joint for connecting the neighboring connecting beams 22 .

At this time, each of the connection connectors 110 includes a main block 120 , a rib 130 , a rotation assembly fixing part 140 , and a close contact guide part 150 .

The main block 120 is brought into contact with each end of the adjacent connecting beam 22 arranged on a straight line for connection. Accordingly, the main block 120 serves to support the end of the corresponding connecting beam (22). Of course, the main block 120 is applicable to various shapes and various materials.

In particular, at least some of the plurality of main blocks 120 provided on the lowermost side of the frame 20 may include an adjuster 24 or a caster (not shown).

And, the ribs 130 extend (branch) in multiple directions from the main block 120, respectively. At this time, the rib 130 can be applied in various ways, such as circular or polygonal in cross section. In particular, the rib 130 is not limited to a length extending from the corresponding main block 120, and is not limited to a number extending in multiple directions.

The rotating assembly and fixing part 140 presses the inner surface of the connecting beam 22 when the connecting beam 22 rotates by a certain angle in the circumferential direction while the shaft is inserted into the connecting beam 22, thereby connecting the connecting beam 22. It serves to be fixed to the rib (130).

To this end, the rotating assembly and fixing unit 140 includes a pressing protrusion 142 and a rotary block 144 .

The pressing protrusions 142 are provided on the circumferential surface of each of the ribs 130 to be spaced apart by a set interval along the circumferential direction, and one or more protrusions are formed along the axial direction of the ribs 130 . A plurality of pressing protrusions 142 are provided to press the inner surface of the corresponding connecting beam 22 , and to increase the pressing force on the connecting beam 22 . At this time, the pressing protrusion 142 may have a curved end to prevent the pressing portion of the connecting beam 22 from being deformed or damaged.

And, the rotary block 144 is provided on the circumferential surface of the rib 130 so as to be rotatable with respect to the rib 130 . At this time, the rotary block 144 may be formed in a tube shape to insert the corresponding ribs 130 , and may be divided into a plurality and assembled with each other while surrounding the corresponding ribs 130 . For convenience, the rotary block 144 is shown to be assembled with each other after wrapping the rib 130 while being divided into a plurality.

In addition, the rotary block 144 is axially inserted into the corresponding connecting beam 22 . Therefore, it is assumed that the rotary block 144 is formed to have the same shape as the inner surface of the connecting beam 22 in cross-section.

In addition, the rotary block 144 is made of the same shape as the inner surface of the connecting beam 22, and when rotated by a set angle by the rotational force acting on the connecting beam 22, the corresponding pushing force of the pressing protrusion 142 is applied. is expanded by pressing and fixing the inner surface of the connecting beam 22, and through an opening hole 145 in the circumferential surface to allow exposure of the pressing protrusion 142 in the initial state.

In other words, the inner surface of the connecting beam 22 and the rotary block 144 is made of the same polygonal shape. For convenience, it is assumed that the connecting beam 22 and the rotary block 144 have a rectangular shape.

In addition, the rotary block 144 forms a corner portion 147 on the inside to maximize the pressing force of the pressing protrusion 142 in a state that does not coincide with the corresponding opening hole 145 .

More specifically, initially, the pressing protrusion 142 is exposed to the outside through the opening hole 145 of the rotary block 144 . In this state, when the connecting beam 22 is axially inserted into the corresponding rotary block 144 , the pressing protrusion 142 does not come into contact with or simply comes into contact with the inner surface of the connecting beam 22 .

After that, when the rotary block 144 is rotated by a set angle together with the connecting beam 22, the pressing protrusion 142 of the rib 130 is positioned at the corresponding corner portion 147, so that it has a substantially rectangular shape. The rotary block 144 presses the inner surface of the connecting beam 22 by a predetermined expansion of each corner portion and is in close contact with the inner surface of the connecting beam 22 . Thus, the connecting beam 22 is prevented from being arbitrarily separated from the rotary block 144 .

In particular, in the initial state, as the pressing protrusion 142 is positioned inside the corresponding opening hole 145 , the rotary block 144 is positioned so as not to move more than a set value along the axial direction of the rib 130 . .

And, the rib 130 forms a flange 143 connecting the pressing protrusion 142 disposed on the same trajectory in the circumferential direction on the circumferential surface. The flange 143 prevents deformation of the pressing protrusion 142 for pressing the inner surface of the corner portion 147 by connecting and supporting the pressing protrusion 142 .

Of course, the flange 143 is deformable in various shapes.

On the other hand, the rotary block 144 is rotated without being separated outward along the axial direction of the rib 130 by the close contact guide 150 and is guided to move by a set distance along the axial direction of the rib 130 . That is, when the rotary block 144 rotates in the assembly direction together with the connecting beam 22 with the shaft inserted into the connecting beam 22, the connecting beam 22 moves together with the rotary block 144 and the corresponding main block (120) is in contact with or is in close contact.

When the rotary block 144 is rotated by the close contact guide 150 , a gap between the assembled connecting beam 22 and the corresponding main block 120 is not generated.

For example, the close contact guide 150 includes an edge 152 , a first protrusion 154 , and a second protrusion 156 .

The edge 152 is provided on one side of the rib 130 . In this case, 'one side' means a position opposite in the axial direction to the other side of the rib 130 connected to the main block 120 .

The edge 152 serves to prevent the tubular rotary block 144 from being arbitrarily separated to one side of the rib 130 . Of course, the edge 152 is deformable in various shapes.

In addition, the first protrusion 154 is formed to protrude from the edge 152 . For convenience, the first protrusion 154 protrudes from the edge 152 in the direction of the pressing protrusion 142 . At this time, one or more first protrusions 154 are provided.

In addition, the second protrusion 156 protrudes from one side of the rotary block 144 , and when matched with the first protrusion 154 , serves to move the rotary block 144 toward the main block 120 .

At this time, as the rotary block 144 is rotated in the circumferential direction with respect to the rib 130 and the first protrusion 154 and the second protrusion 156 coincide with each other, the pressing protrusion 142 of the rib 130 is connected to the connecting beam. While gradually pressing the inner surface of the (22), the connecting beam (22) is moved to the main block (120) to guide it to be in close contact. One or more second protrusions 156 may be provided, and an inclined surface may be formed to guide the movement of the first protrusions 154 .

And, the rib 130 may be provided integrally with the main block 120, but it is assumed that the rib 130 is detachably provided on the main block 120 to enable individual replacement in case of damage.

To this end, the rib 130 passes through the through hole 132 along the axial direction, and the fastening screw 134 is inserted into the through hole 132 for assembling the rib 130 and is then bound to the main block 120 . do.

As a result, the connecting beam 22 is fixed to the connecting connector 110 by the pressing of the pressing protrusion 142 when the rotary blocks 144 corresponding to both sides are forcibly rotated in the circumferential direction after the shaft is inserted in the axial direction. , in contact with or in close contact with the main block 120 . Therefore, the prefabricated furniture 10 according to the present invention is remarkably improved in assembly, thereby facilitating expansion of the storage space.

In particular, referring to FIG. 6 , when the connecting beam 22 is forcibly rotated in one direction by a set angle, the main block 120 of each of the connecting connectors 110 on both sides is connected to the connecting beam 22 by the close contact guide 150 . ) is moved so as to be in contact with the corresponding circumferential surface of

In addition, the fixing support 200 serves to easily assemble and fix the shelf 30 to the connecting beam 22 assembled with each other by the connecting connector 110 after being disposed along the set trajectory on the same plane. 210 , a supporter 220 , a cradle 230 , a receiving groove 240 and a blocking cap 250 .

The holder 210 is formed in a hole or groove shape on the inner surface facing the connecting beam 22 .

The supporter 220 is supported to be face-to-face with the corresponding connecting beam 22 , and serves to support the corresponding shelf 30 . In this case, the lower side of the shelf 30 may be supported by the supporter 220 , and the edge may be in contact with the inner surface of the connecting beam 22 to be fixed in position. Of course, the supporter 220 is applicable to various shapes and various materials.

Then, the cradle 230 extends to be bent from the circumferential surface of the supporter 220, and after being partially inserted into the corresponding holder 210, the direction is changed and completely inserted, the supporter 220 is connected to the connecting beam 22 ) will be interviewed and held.

That is, the cradle 230 has a substantially 'knee (b) shape' shape, and the bent edge is in contact with the inner surface of the connecting beam 22 , and the portion extending from the supporter 220 is the inside of the holder 210 . By being in contact with the side, the supporter 220 is firmly supported on the cradle 230 with respect to the connecting beam 22 .

At this time, since the supporter 220 is supported by being in contact with the connecting beam 22 , the supporter 220 is firmly fixed even in a state in which bolting is not assembled to the connecting beam 22 .

Of course, the cradle 230 is deformable in various shapes.

In addition, the receiving groove 240 is formed to be opened downwardly on the shelf 30 to accommodate the corresponding supporter 220 . Since the supporter 220 is accommodated in the corresponding receiving groove 240 , the position setting operation of the shelf 30 is facilitated and the position of the shelf 30 is fixed. In particular, as the shelf 30 forms the receiving groove 240 in the shape of a groove that is opened only in the downward direction rather than a hole opening in the upward direction, it is difficult for the supporter 220 to be exposed in the upper direction of the shelf 30 . is prevented

And, the blocking cap 250 prevents the supporter 220 from being exposed at the lower part of the shelf 30 .

At this time, the blocking cap 250 blocks each receiving groove 240 or the supporter 220 of the shelf 30 to prevent the supporter 220 from being exposed to the lower side of the shelf 30 . In particular, although not shown, the bolt may bind the supporter 220 and the shelf 30 . In addition, the blocking cap 250 is applicable to various shapes and various materials.

For reference, various embodiments of the assembly unit 100 according to the present invention are disclosed in FIG. 9 .
