       FIG. 1  is a diagram illustrating a movable integrated table according to an embodiment of the present invention,  FIG. 2  is an exploded view showing the movable integrated table shown in  FIG. 1 , and  FIG. 3  is a view showing a cross-section of an upper plate taken along line A-A′ shown in  FIG. 1 . 
     Referring to  FIGS. 1 to 3 , the movable integrated table  10  according to the embodiment of the present invention includes an upper plate  11  configured such that various items, e.g., various business documents, various members (laptops, PCs, various documents, reference materials, samples, etc.) required for business processing, beverages or foods, and various members (cups, etc.) required for the intake of the beverages and foods, are placed thereon. 
     As shown in  FIG. 2 , the upper plate  11  has a flat plane structure having a flat top surface so that various items placed on the top surface do not slip or fall. 
     In this case, the shape of the upper plate  11 , i.e., the shape of the frame, is not limited. For example, it may have a circular shape, a polygonal shape, an oval shape, or a shape having a plurality of curved surfaces. 
     A first separation prevention protrusion  111  is formed along the circumferences of the remaining portions of the upper plate  11  other than both side portions (both side portions to which a pair of folding plates  14  are coupled) thereof in one direction, i.e., in the widthwise direction, and protrudes upward to a predetermined height. Through this, various items placed on the top surface of the upper plate  11  are prevented from being separated and falling from the outside of the upper plate  11 . 
     The first separation prevention protrusion  111  is composed of a thin plate, preferably a metal plate, more preferably a brass plate in order to improve aesthetics and decorativeness. In order to improve decorativeness, various decorations  111   a  are formed on the side of the first separation prevention protrusion  111  by a printing, engraving, or perforation method. In this case, such a decoration  111   a  may be implemented as any one of a sign, a pattern, a shape, a figure, and a character. 
     Furthermore, a handle  112  is installed on one side of the top surface of the upper plate  11  to push and move the movable integrated table  10 . In this case, the handle  112  may be formed, e.g., in an ‘inverted U,’ ‘sideways U,’ or ‘-’ shape. 
     However, the handle  112  of the present invention is not limited to an ‘inverted U,’ ‘sideways U,’ or ‘-’ shape, but may be formed in various structures. Furthermore, a grip part made of wood or synthetic resin may be further provided in the middle of the handle  112  in order to provide a grip feeling and a design of painting. 
     As shown in  FIGS. 1 and 2 , the movable integrated table  10  according to the embodiment of the present invention includes a lower plate  12  installed in parallel with the upper plate  11  in a horizontal direction under the upper plate  11  and configured such that various items are accommodated thereon like the upper plate  11 . 
     The lower plate  12  is fixed below the upper plate  11  through a plurality of posts, preferably four posts  13 . In other words, the bottom side of the upper plate  11  is fixedly supported on the top side of the lower plate  12  through the posts  13 . 
     Like the upper plate  11 , the lower plate  12  is formed such that the top surface thereof has a flat planar surface. Furthermore, there is formed a second separation prevention protrusion  121  protruding upward to a predetermined height along the circumference of the lower plate  12  and configured to prevent various items placed on the top surface of the lower plate  12  from being separated and falling from the lower plate  12 . 
     Like the first separation prevention protrusion  111 , the second separation prevention protrusion  121  is made of a thin metal plate, preferably a brass plate, in order to improve aesthetics and decorativeness. Like in the first separation prevention protrusion  111 , various decorations  121   a  implemented as any one of a sign, a pattern, a shape, a figure, and a character are formed on the side of the second separation prevention protrusion  121  by a printing, engraving, or perforation method. In this case, such a decoration  121   a  formed on the second separation prevention protrusion  121  may be formed in the same pattern as the decoration  111   a  formed on the first separation prevention protrusion  111  in order to provide overall unity. 
     The lower panel  12  may be provided with one or more container storage members  122  for storing various containers, such as bottled water containers, various alcoholic beverages (wine bottles), writing instruments, and the like. In this case, the container storage members  122  may be composed of a plurality of barrels. In addition, they may be each formed in a circular ring structure. 
     Meanwhile, the container storage members  122  may each have an inclined structure inclined outward so that a user or a service provider can easily withdraw various containers stored therein. For example, the inclination of the container storage members  122  may be formed to be approximately 10° to 50°. 
     The posts  13  are installed by fixedly supporting the upper plate  11  with the bottom portion of the upper plate  11  spaced apart from the top portion of the lower plate  12  by a predetermined height, and are adjustable in their height. A total of four posts  13  may be installed, one at each corner. The posts  13  may be each constructed in a circular rod structure as an example. 
     As shown in  FIGS. 1 and 2 , the movable integrated table  10  according to the embodiment of the present invention includes the pair of folding plates  14  that are coupled to both side ends of the upper plate  11 , e.g., both side ends in one side (widthwise) direction of the upper plate  11 , through the hinge members  15  in the form of flaps and are folded downward. 
     The pair of folding plates  14  are rotatably coupled to both ends of the upper plate  11  through the hinge members  15 , and function as expansion plates that expand the area of the upper plate  11  in the widthwise direction. Through this, it is made possible to increase the quantity of various items that can be placed on the top surface of the upper plate  11 . 
     As shown in  FIGS. 1 and 2 , a third separation prevention protrusion  141  is formed to protrude upward to a predetermined height along the circumferences of the remaining portions of each of the folding plates  14 , other than one side portion thereof coupled to the upper plate  11  through the hinge members  15 , in order to prevent various items, i.e., alcoholic beverages and snacks, or various members, placed on the top surface from being separated to the outside. 
     Like the first separation prevention protrusion  111 , the third separation prevention protrusion  141  is made of a thin metal plate, preferably a brass plate, in order to improve aesthetics and decorativeness. Like in the first separation prevention protrusion  111 , various decorations  141   a  implemented as any one of a sign, a pattern, a shape, a figure, and a character are formed on the side of the third separation prevention protrusion  141  by a printing, engraving, or perforation method. In this case, such a decoration  141   a  formed on the third separation prevention protrusion  141  may be formed in the same pattern as the decoration  111   a  formed on the first separation prevention protrusion  111  in order to provide overall unity. 
     As shown in  FIGS. 1 to 3 , the movable integrated table according to the embodiment of the present invention includes a stopper support  16  that is fixedly installed to traverse the bottom of the upper plate  11  in the widthwise direction. 
     The stopper support  16  is composed of a flange  161  which has a ‘U,’ ‘sideways U,’ or ‘-’ shaped cross section, as shown in  FIG. 3 , and both upper ends of which are bent outward, and is fastened to the bottom of the upper plate  11  through fastening members such as screws (pieces) passing through fastening holes formed in the flange  161 . 
     Furthermore, as shown in  FIGS. 1 to 3 , the movable integrated table  10  according to the embodiment of the present invention includes a pair of stoppers  17  that are coupled along the stopper support  16  in a sliding manner. 
     The pair of stoppers  17  are coupled to be slidable along the groove  162  of the stopper support  16  in the longitudinal direction. Through this, the rotation of the pair of folding plates  14  is locked or released. 
       FIGS. 4 and 5  are views illustrating a process in which a pair of folding plates are unfolded or folded according to the present invention.  FIG. 4  is a view showing a state in which the pair of folding plates are unfolded, and  FIG. 5  is a view showing a state in which the pair of folding plates are folded downward at a right angle. 
     After the pair of folding plates  14  are unfolded to be horizontally parallel with the upper plate  11 , as shown in  FIG. 4 , the pair of stoppers  17  are drawn out from the stopper support  16  in directions away from each other. 
     Accordingly, the bottoms of the pair of foldable plates  14  are supported by the pair of stoppers  17  drawn out from the stopper support  16  and maintained in an unfolded state without being folded downward by their own weight, so that the area of the upper plate  11  can be expanded by the size of the pair of folding plates  14 . 
     In the state where the pair of folding plates  14  are unfolded, it is necessary to reduce the expanded area by folding the pair of folding plates  14  downward at a right angle in order to move to a narrow place within a pub. To this end, the expanded area is reduced by sliding the pair of stoppers  17  into the inside of the stopper support  16  and then folding the pair of folding plates  14  downward. 
     Meanwhile, a handle  171  bent downward is formed at an outer end of each of the pair of stoppers  17 . A user can slide the stopper  17  by pushing or pulling the stopper  17  to and from the stopper support  16  while holding the stopper  17  with a finger by using the handle  171 . 
     As shown in  FIGS. 1 and 2 , the movable integrated table  10  according to the embodiment of the present invention includes a pair of front wheels  18  and a pair of rear wheels  19  installed on the bottom of the lower plate  12 . 
     The pair of front wheels  18  are formed in forward and backward directions to have a smaller diameter than the pair of rear wheels  19 , and are fixed to move only in the forward and backward directions and not to rotate a rotation direction in order to be advantageous when the movable integrated table  10  moves up stairs. It will be apparent that the pair of front wheels  18  may be formed to have a larger diameter than the pair of rear wheels  19 . In addition, the pair of rear wheels  19  may be rotated 360° so that they can freely move forward, backward, leftward, and rightward. 
     Meanwhile, a rubber plate may be further installed on the top surface of each of the upper plate  11  and the lower plate  12  as a slide prevention member so that alcoholic beverages and snacks, or various members placed on the top surface do not slide. 
       FIG. 6  is a view showing a movable integrated table manufactured based on a movable integrated table according to an embodiment of the present invention, and  FIG. 7  is a view showing a state where the pair of folding plates shown in  FIG. 6  have been folded. 
     Referring to  FIGS. 6 and 7 , the movable integrated table  20  according to the present invention has the same configuration as the movable integrated table  10  shown in  FIGS. 1 to 5 . In other words, it includes an upper plate  21 , a lower plate  22 , posts  23 , and a pair of folding plates  24 . It further includes hinge members for folding and supporting the pair of folding plates  24 , a stopper support, and a pair of stoppers. 
     The upper plate  21  and the lower plate  22  differ from the upper plate  11  and the lower plate  22  shown in  FIGS. 1 to 5  in shape and material, but the functions and effects thereof are the same. For example, the upper plate  11  may be formed in a structure in which the edges thereof are connected by a plurality of curved surfaces, and may be made of wood (solid wood, or plywood), a synthetic resin plate, or the like. The design and decoration thereof may be improved by engraving various patterns and then performing painting on the surface. 
     Meanwhile, the luxury and elegance of the pair of front wheels  28  are improved by painting wheel parts and ribs in gold color. In addition, the pair of front wheels  18  is formed to have a larger diameter than the pair of rear wheels  29 , and is fixed to move only in the forward and rearward directions and not to rotate in a rotation direction in order to be advantageous when the movable integrated table  10  moves up stairs. In addition, the pair of rear wheels  29  may be rotated 360° so that the table  20  can freely move forward, rearward, leftward, and rightward. 
     Meanwhile, the handle  212  may be formed, e.g., in an ‘inverted U,’ ‘sideways U,’ or ‘-’ shape. A grip part  212   a  fabricated into various shapes using a material such as wood or synthetic resin material may be further provided in the middle of the handle  212  in order to improve luxury and elegance while improving a grip feeling. 
     Furthermore, container storage members  222  may each be formed in a circular ring structure to accommodate various containers, e.g., bottled water containers (bottles) or various bottles. For example, as shown in  FIG. 6 , the container storage members  222  may have a structure in which three circular rings are connected to each other. 
     As described above, the technical spirit of the present invention has been described in detail in conjunction with the preferred embodiments, but the preferred embodiments are intended not for limitation but for illustration. Therefore, those of ordinary skill in the art will appreciate that various embodiments may be possible through the combination of the embodiments of the present invention within the scope of the technical spirit of the present invention.
