Hereinafter, the structure, technical means, and functions of a preferred embodiment of the present invention will be described with reference to the drawings.
A multifunction folding table according to an embodiment of the present invention mainly includes a lower support column 10 and a table surface 20.

  Among these, the lower support column 10 has an E-shaped base 11. A caster 12 is installed at the bottom of the D-shaped base 11 to provide a moving function. A vertical pipe 13 is installed at one end of the horizontal stem of the U-shaped base 11. A fastening cover 14 that can be quickly detached is fitted at the tip of the vertical pipe 13. At the same time, by having a fixed introduction protrusion 131 recessed inward at a predetermined position on the inner wall surface of the pipe close to the tip of the vertical pipe 13, the expansion and contraction is performed in correspondence with the introduction groove 151 installed on one side of the expansion and contraction pipe 15. An introduction function of extending and contracting the vertical pipe 13 corresponding to the pipe 15 in the vertical direction is formed, and the expansion pipe 15 is prevented from rotating. The fastening cover 14 allows the telescopic pipe 15 and the vertical pipe 13 to be smoothly fitted and fixed firmly. When the telescopic pipe 15 is extended to the top, the elastic fixing projection 152 previously installed at the lower end thereof corresponds to the fixing hole 132 at the upper end of the vertical pipe 13 to form a firm fixing relationship. Therefore, the extension pipe 15 is prevented from being detached. A table surface 20 is installed by connecting the pivot joint 16 to the distal end of the telescopic pipe 15. The telescopic pipe 15 penetrates through the bottom of the pivot joint 16 through the through hole 161.

  The table surface 20 is surrounded by a decorative frame 21. The altitude of the decorative frame 21 slightly protrudes from the table surface 20 and has a function of fixing and not moving the installation object 30 even when the table surface 20 is inclined. Further, a T-shaped frame column 22 is provided at a position slightly deviated from the side surface at the bottom of the table surface 20. A saddle-shaped pivot part 23 is installed on the outer lower edge of the frame column 22. The inner diameter of the pivot part 23 just corresponds to the outer diameter of the pivot joint 16 of the telescopic pipe 15 of the lower column 10. The shaft screw 24 passes through the pivot hole 162 and the pivot hole 231 previously installed in the pivot joint 16 and the pivot part 23, and the screws 241 are combined, and then tightened by the shaft screw 24 from the other to be coupled. Assembling by connection is completed, and the table surface 20 has a function of adjusting the rotation inclination by shaft connection.

  Further, in order to stabilize the inclination angle of the table surface 20, an elongated hole 163 is installed below the pivot hole 162 of the outer piece of the pivot joint 16 of the telescopic pipe 15 of the lower column 10. A corresponding shaft hole 164 is provided in the inner piece. At the same time, the outer piece of the pivot part 23 of the frame column 22 at the bottom of the table surface 20 has a large area, and has a substantially semicircular curved introduction groove 232 below the pivot hole 231. A plurality of fixing grooves 233 extend on the lower edge of the curved introduction groove 232, and the lever control bar 17 passes through the curved introduction groove 232 of the pivot part 23 and the elongated hole 163 of the outer piece of the pivot joint 16. After that, the other end is axially connected to the shaft hole 164 of the inner piece of the pivot joint 16 and at the same time pulled between the middle stage of the lever control bar 17 and the hole in the introduction groove 151 located at the upper stage of the telescopic pipe 15. A spring 18 is hooked and installed. The tension spring 18 applies a pulling action to the lever control bar 17, pulls the lever control bar 17 downward, and fixes it in the fixing groove 233 extending from the lower edge of the curve type introduction groove 232 of the pivot part 23. The relative relationship between the table surface 20 and the lower support column 10 is stably maintained.

  When adjusting the inclination angle of the table surface 20, the lever control bar 17 can be detached from the fixing groove 233 of the pivot part 23 simply by raising the lever control bar 17 upward. At the same time, the tension spring 18 is pulled. At this time, if necessary, the table surface 20 can be tilted in any direction of the table surface 20 as required by the inclination angle of the table surface 20 and the lever control bar 17 can be lifted up by loosening the lever control bar 17. By the pulling action when returning to the original position, the lever control bar 17 can be fixed and fitted again in the fixing groove 233 to obtain the fixing action of the table surface 20. This provides a plurality of angle adjustment functions flexibly for different needs.

  In addition, the table surface 20 can be adjusted by adjusting the inclination angle by combining a plurality of fixing grooves 233 at the lower edge of the curved introduction groove 232 with a substantially semi-circular under half shape. The table surface 20 can have a plurality of angle adjustment functions in both the forward and reverse directions. Therefore, it is possible to make adjustments flexibly according to actual needs, and there is no need to change the combination relationship between the table surface 20 and the lower support column 10 without being restricted by the arrangement of the bed or the dominant hand of the individual. Folding tables can be installed on the left or right side as needed, which is very convenient for use. That is, the labor and inconvenience caused by changing the installation relationship of the table surface are eliminated, and at the same time, there are no restrictions on the place of use and space.

  Further, the design of the semicircular curve-type introduction groove 232 of the pivotal part 23 of the table surface 20 makes the shape nearly vertical when adjusting the table surface 20 and can be used as a whiteboard bulletin board (see FIG. 10). It is also possible to write a letter on it, or to attach a document, a notice or the like by giving a magnetic effect to the table surface 20 (see FIG. 11). Therefore, the multi-functional folding table according to an embodiment of the present invention has a flexible multi-functionality that can be used not only for the bedside but also for other different uses.

  As described above, the multi-functional folding table of the present invention is used at the bedside and has multi-purpose functions such as a whiteboard and a bulletin board, as well as being used for meals, reading, writing, and computer operations. In addition to having the function to adjust the height of the table surface, in the assembly relationship by connecting the table surface and the lower column, the lever control bar and the pivotal part curve type introduction groove and a plurality of fixed grooves extending to the lower edge With a design that combines the table surface, the table surface tilt angle can be adjusted flexibly according to different usage requirements and space conditions by adjusting the table surface with various tilt angles in both the forward and reverse directions.
