Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an assembly box for transportation and, more specifically, to an assembly box for transportation capable of facilitating the loading and unloading of articles into and from the assembly box, preventing damage such as rupture or the like of corner portions by disposing corner brackets in the corner portions, preventing distortion of the assembly box during an assembly process through the use of a structure in which brackets are fitted between frames, and providing a stable framework. 
       BACKGROUND 
       [0002]    In general, a large-capacity packing box for transportation is used as a means for safely and conveniently transporting a large quantity of goods exchanged in a series of product distribution processes between a manufacturer, a merchant and a consumer and in an export/import process. 
         [0003]    Depending on the features (the fragileness, the size, etc.) of goods accommodated therein, different kinds of packing boxes for transportation such as a paper box made of a corrugated board, a wood box made of wood, a plastic box made of plastic and a container box made of a steel plate are manufactured and selectively used. The packing boxes for transportation differ only in material from each other. The overall structures of the packing boxes have a simple rectangular box shape with an accommodation space formed therein. 
         [0004]    In the meantime, when the packing boxes are recovered after moving the packing boxes which contain goods or when the packing boxes are stored in an empty state, the volume of the packing boxes remains unchanged even though the packing boxes are empty. Thus, a large space and an increased cost are required for storing and transporting the empty packing boxes. 
         [0005]    In order to solve this problem, there has been developed and used an assembly box for transportation capable of maintaining a rectangular box shape as in the related art when moving the assembly box which contains goods and capable of minimizing the volume when recovering the assembly box or when storing the assembly box in an empty state. That is to say, the assembly box for transportation may be unfolded in a rectangular box shape when transporting goods and may be folded to have a minimized volume when recovering the assembly box. 
         [0006]    In this connection, a “foldable container palette system” (Korean Utility Model Registration No. 20-0417505 may be referred to. 
         [0007]    As illustrated in  FIGS. 23 to 24 , the foldable container palette system of the related art includes a box  10 , a palette  20  and a lid  30 . The box  10  may be folded to reduce the volume thereof during transportation and storage. 
         [0008]    The box  10  includes several plastic panels  11  and  12 , four corner folding members  13  and two central folding members  14  configured to interconnect the plastic panels  11  and  12  so that the plastic panels  11  and  12  can be folded in their connection portions and overlapped with each other. The plastic panels  11  and  12  are made of a resin so that the plastic panels  11  and  12  have a light weight and a superior workability. 
         [0009]    Each of the corner folding members  13  is disposed in each corner and is configured to interconnect the edges of the plastic panels  11  and  12  adjoining each other. Each of the corner folding members  13  includes a pair of bracket portions  131  formed in a symmetrical shape with respect to each corner and a folding portion  133  configured to foldably interconnect the respective bracket portions  131 . The bracket portions  131  and the folding portion  133  are formed into one piece. 
         [0010]    In each of the bracket portions  131 , there are formed insertion fixation channels  132  having a U-like cross-sectional shape and vertically extending so that the edges of the respective plastic panels  11  and  12  adjoining each other are inserted into and fixed to the insertion fixation channels  132 . The bracket portions  131  make an angle of 90 degrees with each other when the box  10  is unfolded. In the bracket portions  131 , stoppers  131   a  capable of making contact with each other are formed at the opposite side of the insertion fixation channels  132 . 
         [0011]    The folding portion  133  is made of a soft moldable resin so that the folding portion  133  can be easily deformed in order to foldably interconnect the bracket portions  131 . 
         [0012]    As illustrated in  FIG. 25 , each of the central folding members  14  includes a pair of bracket portions  141  and a folding portion  143  configured to foldably interconnect the respective bracket portions  141 . The bracket portions  141  and the folding portion  143  are formed into one piece. In each of the bracket portions  141 , there are formed insertion fixation channels  142  having a U-like cross-sectional shape and vertically extending so that the edges of the respective plastic panels  12  adjoining each other are inserted into and fixed to the insertion fixation channels  142 . The bracket portions  141  make an angle of 180 degrees with each other when the box  10  is unfolded. For this purpose, stoppers  141   a  configured to make contact with each other at an angle of 180 degrees when the box  10  is unfolded are formed in the bracket portions  141 . As with the folding portion  133 , the folding portion  143  is made of a soft moldable resin. 
         [0013]    In the case of the related art, the structurally weak folding members constitute the framework of the box and support the sidewall. Thus, the assembly box may be distorted by an external impact and may have a difficulty in performing a tracking management of the assembly box and a first-in and first-out management of the assembly box according to an incoming date. In particular, since the corner folding members are made of a soft material so that the corner folding members are folded with ease, damage such as rupture or the like may be frequently generated in the corner portions of the box.

     DETAILED DESCRIPTION 
       [0058]      FIG. 1  is a perspective view illustrating an assembly box for transportation according to one embodiment of the present invention.  FIG. 2  is an exploded perspective view illustrating the assembly box for transportation according to one embodiment of the present invention. 
         [0059]    As illustrated in  FIGS. 1 and 2 , the assembly box for transportation according to one embodiment of the present invention includes a main body  100 , which includes sidewalls, frames and brackets, a cover  400  configured to cover an upper end of the main body  100 , and a base  500  and a palette  600  configured to constitute a bottom portion of the main body  100 . 
         [0060]    Specifically, the sidewalls  310  of the main body  100  may be made of a synthetic resin having a light weight and a superior workability, for example, a plurality of plastic panels. The sidewalls  310  may be assembled between the frames. In this regard, the frames may include vertical corner frames  110 , first horizontal frames  121 , second horizontal frames  122 , first vertical reinforcing frames  131 , second vertical reinforcing frames  132 , first vertical rail frames  141 , second vertical rail frames  142 , horizontal reinforcing frames  147  and vertical folding frames  150 . The vertical corner frames  110   
         [0061]    The vertical corner frames  110  are four frames vertically disposed in the corner portions of the assembly box. The vertical corner frames  110  may serve as a framework for supporting the sidewalls  310  of the assembly box. The sidewalls  310  of the main body  100  are assembled with the four vertical corner frames  110 . The upper and lower end portions of the vertical corner frames  110  may be connected to the first horizontal frames  121  and the second horizontal frames  122  through corner brackets  210 . 
         [0062]    The first horizontal frames  121  and the second horizontal frames  122  are frames disposed in the upper and lower edge portions of the main body  100  and may be orthogonally connected to the vertical corner frames  110  interposed therebetween. For example, the first horizontal frames  121  may be defined as longitudinal horizontal frames of the main body  100  connected to one side of the vertical corner frames  110 . The second horizontal frames  122  may be defined as transverse horizontal frames of the main body  100  connected to the other side of the vertical corner frames  110 . In the present embodiment, the first horizontal frames  121  may be formed of at least four frames disposed in the longitudinal upper and lower edge portions of the main body  100 . The second horizontal frames  122  may be formed of at least four frames disposed in the transverse upper and lower edge portions of the main body  100 . 
         [0063]    In particular, the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  may be connected to the first horizontal frames  121  through reinforcing brackets  230 . The vertical folding frames  150  may be connected to the second horizontal frames  122  through folding brackets  220 . 
         [0064]    The first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  may be formed of a pair of frames horizontally spaced apart on the mutually-facing sidewall  310 , more specifically on the sidewall  310  positioned at the longitudinal side on the basis of the vertical corner frames  110 . The first vertical rail frames  141  and the second vertical rail frames  142  may be slidably installed in the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132 , respectively. 
         [0065]    The first vertical rail frames  141  and the second vertical rail frames  142  may include upper vertical rail members  143  and lower vertical rail members  144 . In this regard, the upper vertical rail members  143  may be assembled with the upper side of the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  so that they can be slidingly moved in the height direction of the main body  100 . The lower vertical rail members  144  may be slidably coupled to the lower side of the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  and may then be fixed to the first horizontal frames  121  positioned in the longitudinal lower edge portions, by fixing members such as a bolts or the like. 
         [0066]    In this regard, the upper vertical rail members  143 , the lower vertical rail members  144  and the horizontal reinforcing frames  147  may constitute the edge portions of opening/closing sidewalls  311  and fixed sidewalls  312 . The horizontal reinforcing frames  147  may include upper horizontal reinforcing frames  145  configured to provide the edge portions of the opening/closing sidewalls  311  together with the upper vertical rail members  143  and lower horizontal reinforcing frames  146  configured to provide the edge portions of the opening/closing sidewalls  311  together with the lower vertical rail members  144 . 
         [0067]    As the upper vertical rail members  143  are slid at the upper side of the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  in this way, the opening/closing sidewalls  311  may be slidingly moved in the up-down direction in the sidewalls  310  of the main body  100 . As a consequence, the opening/closing sidewalls  311  may easily open and close some portions of the sidewalls  310  of the main body  100 . 
         [0068]    The vertical folding frames  150  may be vertically installed on the mutually-facing sidewalls  310 , more specifically on the sidewalls  310  positioned at the transverse side on the basis of the vertical corner frames  110 . The opposite ends of the vertical folding frames  150  may be connected to the second horizontal frames  122  through the folding brackets  220 . Since the vertical folding frames  150  are formed of a structure capable of being folded in the width direction, the sidewalls  310  of the main body  100  may be folded with respect to the vertical folding frames  150 . 
         [0069]    The brackets of the main body  100  are connection members for interconnecting the frames and may include corner brackets  210 , reinforcing brackets  230  and folding brackets  220 . In this regard, the corner brackets  210  may interconnect the end portions of the vertical corner frames  110  and the end portions of the first horizontal frames  121  and the second horizontal frames  122 . The reinforcing brackets  230  may connect the first vertical reinforcing frames  131  and the second vertical reinforcing frames  132  to the first horizontal frames  121 . The folding brackets  220  may connect the vertical folding frames  150  to the second horizontal frames  122 . 
         [0070]    The cover  400  has a cap structure configured to cover the upper portion of the main body  100  and may be formed in a rectangular plate shape as a whole. The cover  400  may surround and protect the upper end portions of the vertical corner frames  110 , the first horizontal frames  121  and the second horizontal frames  122 . The cover  400  may be provided with rib structures for enhancing the strength of the cover  400 . 
         [0071]    The base  500  may be disposed at the upper side of the palette  600  and may provide a bottom surface of the main body  100 . Base brackets  510  may be provided in the corner portions of the base  500 . Seating grooves  511  and seating projections (not shown) may be formed on the upper and lower surfaces of the base brackets  510 . The seating grooves  511  and the seating projections may fix different brackets stacked one above the other. 
         [0072]    For example, when different bases  500  are stacked one above the other, the seating grooves  511  and the seating projections of the stacked base brackets  510  may be fitted and fixed to each other. Furthermore, when the folded main body  100  and the base  500  are stacked one above the other, the seating grooves  511  and the seating projections of the base brackets  510  may be fitted and fixed to fixing grooves  204  and fixing grooves  203  of the corner brackets  210  which will be described later. 
         [0073]    The palette  600  is a structure for supporting the base  500  and may provide a bottom plate of the assembly box. The lower end portions of the vertical corner frames  110 , the first horizontal frames  121  and the second horizontal frames  122  may be fitted to and assembled with the edge portion of the palette  600 . 
         [0074]    Hereinafter, the configuration of the main body  100  according to one embodiment of the present invention will be described in more detail with reference to the accompanying drawings. 
         [0075]      FIG. 3  is a partially cutaway perspective view of a portion indicated by line “A-A” in  FIG. 1 .  FIG. 9  is an enlarged perspective view of a portion indicated by “G” in  FIG. 2 . 
         [0076]    As illustrated in  FIGS. 3 and 9 , each of the corner brackets  210  may include a first bracket piece  211 , a second bracket piece  212 , a first guide  213  and a second guide  214 . Each of the corner brackets  210  may interconnect the end portion of each of the vertical corner frames  110  and the end portions of each of the first horizontal frames  121  and each of the second horizontal frames  122 . 
         [0077]    The first bracket piece  211  may be fitted to and assembled with the end portion of each of the vertical corner frames  110  and the end portion of each of the first horizontal frames  121  through coupling projections  202 . A first rail groove  201   a , to which the first guide  213  is slidingly coupled, may be formed is one side portion of the first bracket piece  211 . The second bracket piece  212  may be fitted to and assembled with the end portion of each of the vertical corner frames  110  and the end portion of each of the second horizontal frames  122  through coupling projections  202 . A second rail groove  201   b , to which the second guide  214  is slidingly coupled, may be formed is one side portion of the second bracket piece  212 . 
         [0078]    In this case, a fixing groove  203  and a fixing projection  204  may be formed in the first bracket piece  211  and the second bracket piece  212 . The fixing groove  203  and the fixing projection  204  constitute a groove/projection structure for fixing different brackets stacked one above the other. When different corner brackets  210  are stacked one above the other, the fixing groove  203  and the fixing projection  204  of the stacked corner brackets  210  may be fixed and fixed to each other.

         [0103]      FIG. 12  is a partially cutaway perspective view of a portion indicated by line “J-J” in  FIG. 1 . 
         [0104]    As illustrated in  FIGS. 1 and 12 , a mark plate  330  may be mounted to the sidewall  310  of the main body  100  through a removable mounting portion  331 . The removable mounting portion  331  may include magnet pieces  332 , iron bands  333  and a removal groove  314 . 
         [0105]    The magnet pieces  332  may hold the iron bands  333  of the mark plate  330  using a magnetic force and may be fixed to a mounting hole  313  of the sidewall  310  through an engagement claw. In this regard, the engagement claw may include a first engagement claw  332   a  and a second engagement claw  332   b , both of which have a wedge shape. 
         [0106]    For example, the second engagement claw  332   b  is formed in a wedge shape so as to have a thickness larger than the thickness of the first engagement claw  332   a . Thus, a user may first insert the second engagement claw  332   b  into the mounting hole  313 . In this state, the user may insert the first engagement claw  332   a  into the mounting hole  313 . This enables the user to easily mount the magnet pieces  332  to the mounting hole  313 . 
         [0107]    The iron bands  333  may be provided in the mark plate  330  so that the iron bands  333  can be removably mounted to the magnet pieces  332 . In the present embodiment, the iron bands  333  may be positioned in the upper and lower portions of the mark plate  330 . In this case, the magnet pieces  332  may also be positioned in the portions of the removal groove  314  of the sidewall  310  corresponding to the upper and lower portions of the mark plate  330 . 
         [0108]    The removal groove  314  is a groove to which the mark plate  330  is removably mounted. The removal groove  314  may be formed to have the same size as the mark plate  330 . The magnet pieces  332  may be positioned in the upper and lower sides of the removal groove  314 . 
         [0109]      FIG. 13  is an enlarged perspective view of an upper portion of the palette according to one embodiment of the present invention.  FIG. 14  is an enlarged perspective view of a lower portion of the palette according to one embodiment of the present invention.  FIG. 15  is a perspective view illustrating a stacked state of the assembly boxes for transportation according to one embodiment of the present invention. 
         [0110]    As illustrated in  FIGS. 13 to 15 , the palette  600  may include a support portion  630 , coupling portions  620  and accommodation portions  610  and may serve to support the lower portion of the assembly box for transportation. 
         [0111]    The support portion  630  may prevent deflection and may minimize shocks through load distribution by disposing longitudinal reinforcing ribs  631  and transverse reinforcing ribs  632  in a lattice pattern between guides  633 . For example, the support portion  630  may include guides  633  protruding so as to define an outer edge of the support portion  630 , longitudinal reinforcing ribs  631  integrally formed with the guides  633  and configured to provide a plurality of ribs extending in the longitudinal direction, and transverse reinforcing ribs  632  configured to provide a plurality of ribs extending in the transverse direction. 
         [0112]    The coupling portions  620  may have a truncated quadrangular pyramid shape and may protrude so that each of the coupling portions  620  grows narrower from the upper portion toward the lower portion thereof. The coupling portions  620  may be seated and stacked on the cover groove portions of the cover  400  to be described later or may be seated and stacked on the accommodation portions  610  of another palette  600 . In this case, the inclination angle of the truncated quadrangular pyramid of the coupling portions  620  may be set to fall within a range between 75 to 85 degrees. This makes it possible to minimize external impact and to minimize damage through load distribution. 
         [0113]    The accommodation portions  610  may be formed in a truncated quadrangular pyramidal groove shape in the upper portion of the support portion  630 . When only the palettes  600  are stored in a stacked state by dismantling the assembly boxes for transportation, the coupling portions  620  of another palette  600  may be inserted into and stacked on the accommodation portions  610 . 
         [0114]      FIG. 16  is a perspective view illustrating a combined state of the base and the palette according to one embodiment of the present invention. 
         [0115]    As illustrated in  FIG. 16 , the base  500  may include a base plate  530  configured to provide a bottom surface of the main body  100 , base frames  520  configured to define an edge of the base plate  530 , and base brackets  510  configured to interconnect the base frames  520 , each of the base brackets  510  including a seating groove  511  and a seating projection (not shown) formed on the upper and lower surfaces thereof. 
         [0116]    The base  500  may be seated on the palette  600 . In this case, an assembly groove  201 , into which the main body  100  is inserted, may be formed between the guides  633  of the palette  600  and the edge portion of the base  500 . 
         [0117]    The assembly groove  201  is a gap formed between the palette  600  and the base  500  when the palette  600  and the base  500  are coupled to each other. The gap may provide a spaced-apart distance just as much as the thickness of the sidewall of the main body  100 . Thus, when assembling the assembly box for transportation, the assembly groove  201  may serve to stably hold the main body  100 . 
         [0118]      FIG. 17  is an enlarged perspective view of the cover  400  according to one embodiment of the present invention. 
         [0119]    As illustrated in  FIG. 17 , the cover  400  may include a cover portion  430  and cover groove portions and may serve to cover and protect the upper portion of the assembly box for transportation. 
         [0120]    The cover portion  430  may be generally formed in such a shape that the palette  600  can be stacked with ease. The cover portion  430  may be formed so that longitudinal reinforcing ribs  431  and transverse reinforcing ribs  432  intersect each other between guides  433  which define an outer edge of the cover portion  430 . Since the longitudinal reinforcing ribs  431  and the transverse reinforcing ribs  432  are connected in a lattice shape, it is possible to prevent the cover portion  430  from being bent by an external impact and to minimize shocks through load distribution. The cover groove portions may be formed in the edge and the center of the cover portion  430 . 
         [0121]    The cover groove portions may be formed in the upper portion of the cover portion  430  in a depressed shape so that the coupling portions  620  of the palette  600  can be seated on the cover groove portions. The cover groove portions may include corner cover groove portions  410  positioned at the corners of the palette  600  and edge cover groove portions  420  positioned at the edge of the palette  600 . Each of the corner cover groove portions  410  may provide a bent corner rib  411  and a corner rib groove  412 . Each of the edge cover groove portions  420  may provide a straight edge rib  421  and a straight edge rib groove  422 . 
         [0122]    Hereinafter, descriptions will be made on a method folding and stacking the assembly box according to one embodiment of the present invention. 
         [0123]      FIG. 18  is a view illustrating a folded state of the sidewalls of the assembly box for transportation according to one embodiment of the present invention.  FIG. 19  is an enlarged view of a portion indicated by “K” in  FIG. 18 .  FIG. 20  is an enlarged view of a portion indicated by “L” in  FIG. 18 . 
         [0124]    As illustrated in  FIGS. 18 to 20 , the main body  100  of the assembly box may be folded using the vertical folding frames  150  and the vertical corner frames  110 . 
         [0125]    Specifically, if the sidewalls  310  positioned in the transverse direction are folded inward of the main body  100  about the hinge members  107  of the vertical folding frames  150 , the hinge members  107  of the vertical corner frames  110  are folded outward of the main body  100 . Thus, the sidewalls  310  positioned in the longitudinal direction may be overlapped with each other. 
         [0126]      FIG. 21  is a view illustrating a state in which the multiple sidewalls of the assembly box for transportation according to one embodiment of the present invention are folded and stacked on the palette.  FIG. 22  is a view illustrating a state in which the multiple assembly boxes for transportation according to one embodiment of the present invention are stacked. 
         [0127]    As illustrated in  FIGS. 21 and 22 , when recovering or storing the assembly box, the components of the assembly box, for example, the palette  600 , the base  500 , the main body  100  and the cover  400 , may be stacked in a mutually-overlapping state and may be bound by a band  700 . 
         [0128]    In the present embodiment, the components obtained by dismantling ten assembly boxes are stacked ten by ten and are bound by the band  700 . For example, ten palettes  600  are stacked in a mutually-overlapping state. Then, ten bases  500  are stacked in a mutually-overlapping state and are placed on the stacked palettes  600 . At this time, the ten bases  500  may be fixed to one another using the searing grooves  511  and the seating projections. 
         [0129]    After the bases  500  are placed on the palettes  600 , ten folded main bodies  100  are stacked on the bases  500  in a mutually-overlapping state. At this time, the seating grooves  511  of the uppermost one of the ten bases  500  and the fixing projections  204  of the corner brackets  210  of the lowermost one of the main bodies  100  may be fixed to each other. The ten main bodies  100  may be fixed to one other using the fixing projections  204  and the fixing roves  203  of the corner brackets  210 . 
         [0130]    After the main bodies  100  are stacked on the bases  500 , ten covers  400  are stacked on the main bodies  100  in a mutually-overlapping state. After the components of the assembly boxes (e.g., the palettes  600 , the bases  500 , the main bodies  100  and the covers  400 ) are sequentially stacked in this way, the components of the assembly boxes are bound in a lattice pattern using the band  700  and are transported or stored in a warehouse. 
         [0131]    As described above, the embodiments of the present invention have an advantage in that, by providing the corner brackets in the corner portions, it is possible to prevent damage such as rupture or the like of the corner portions. Furthermore, the embodiments of the present invention have an advantage in that it is possible to prevent distortion of the assembly box during an assembly process and to provide a stable framework through the use of a structure in which the brackets are fitted between the frames. Furthermore, the embodiments of the present invention have an advantage in that, by installing an RFID chip, which provides product information, in the handle of the assembly box, it is possible to easily perform a tracking management of the assembly box and a first-in and first-out management of the assembly box according to an incoming date. Furthermore, the embodiments of the present invention have an advantage in that, by removably installing the mark plate in the sidewall of the assembly box, it is possible to easily replace the information on the goods accommodated within the assembly box and to remove the mark plate during the cleaning process of the assembly box, thereby preventing damage and contamination of the mark plate.
