The connecting member 20 is formed of a tubular metal material and is formed to be bent downwardly from the connecting portion 21 and the connecting portion 21 extending laterally from the support member 52 of the chair member 50 and the first space portion. A second through the first through hole 250 formed in the pivoting support 40 and protruding downwardly from the pivoting part 22 and the pivoting part 22 to be rotatably coupled to the head 41. It is composed of a protrusion 23 extending into the space 42.

In addition, the first friction reducing member 300 is attached to the lower end of the rotating part 22 of the connecting member 20 by an adhesive or press-fitting, and the first friction reducing member 300 is attached thereto. ) Is preferably formed of a synthetic resin material to reduce the noise or frictional force that may occur when the rotating part 22 coupled to the first space part 41 to rotate smoothly.

The protrusion 23 is positioned in the second space 42 through the first through hole 250, and a thread 25 is formed to fasten the nut member 80 to an outer circumferential surface of the lower end. The second cut groove 210 is formed at one side of the lower end to provide a space for engaging the inner end of the first elastic member 90.

In addition, the length of the protrusion 23 is the pivot support 40 in the first through hole 250 to couple the cap member 70 to the lower end of the pivot support 40 and to fasten the nut member 80. It is preferably formed longer than the length to the bottom of the).

The first elastic member 90 is formed of a spiral spring wound spirally of a metal plate having an elastic force, the inner end is engaged with the second incision groove 210 of the protrusion 23, the outer end is pivot The first cutting groove 200 of the earth 40 is engaged to provide a function of applying an elastic force to the inside of the table top plate 100 with respect to the connecting member 20.

In addition, since the first elastic member 90 is accommodated in the second space portion 42 formed at the lower portion of the rotation support 40, the first elastic member 90 has an advantage of being easy to attach and detach when assembling.

The cap member 70 has a second through hole 260 corresponding to the first through hole 250 in the center of the bottom surface of the ordinary, and the protrusion 23 is the second through hole 260. It is coupled to pass through) is fastened to the nut member (80).

The fastened nut member 80 serves to stably maintain the connection member 20 coupled to the pivot support 40.

According to an embodiment of the present invention as described above when the user discharges the chair member 50 located inside the table top plate 100 to the outside of the table top plate 100, the first incision groove 200 and the second incision The spirally wound first elastic member 90 coupled to the groove 210 is wound, and when the user sits on the seat plate 51 of the chair member 50 and applies a load downward, the support member 52 is attached to the support member 52. Restoring force of the elastic member that the support member 52 is in close contact with the ground so that the user can sit and the elastic member for applying the elastic force is installed upward, and the support member 52 in close contact with the ground is compressed when the user stands up after use The chair member 50 coupled to the other side of the connecting member 20 is returned to the inside of the table top plate 100 while the first elastic member 90, which is spaced apart from the ground and wound at the same time, is released by the restoring force. I will go.

Figure 5 is an exploded perspective view of the components constituting the rotating structure according to another embodiment of the automatic folding chair integrated table of the present invention, Figure 6 is a configuration of the rotating structure according to another embodiment of the automatic folding chair integrated table of the present invention A cross-sectional view of parts in a coupled state.

5 and 6, another embodiment of the present invention further includes a second elastic member 91 in one embodiment.

The second elastic member 91 has a third through hole 270 corresponding to the first through hole 250 in the center of the second elastic member 91 and is coupled to the protrusion 23 of the connection member 20. The second friction reducing member 310 and one end is configured to include a coil spring 67 is fixedly coupled to the upper surface of the second friction reducing member 310.

The other end of the coil spring 67 of the second elastic member 91 is fixedly coupled to the lower surface of the first friction reducing member 300 and is coupled to the first space portion 41 of the rotation support 40 so as to rotate. It provides a function to apply an elastic force upward to the 22, the second friction reducing member 310 is made of synthetic resin material to reduce the noise and friction force generated when the rotation is coupled to the first space portion 41 It is preferably formed.

In this case, the second elastic member 91 is fixedly coupled to the first friction reducing member 300 fixed to the pivoting part 22 to increase the length accommodated in the first space part 41. The first space portion 41 is formed in a length sufficient to accommodate the pivoting portion 22 and the second elastic member 91 of the connecting member 20.

In addition, the rotation support 40 should also be formed to a sufficient length to form a second space portion 42 to accommodate the first elastic member 90 when the bushing member 30 is inserted.

In addition, the depth of the first cutting groove 200 of the protrusion 23 is fixedly coupled to the second elastic member 91 so that the rotating part 22 accommodated in the first space 41 may move in the vertical direction. It should be formed larger than the compression depth of the coil spring 67.

In addition, since the second elastic member 91 having a restoring force upward is further formed in the first space portion 41 of the rotation support 40, the support member 52 of the chair member 50 is connected to the connection member 20. It is possible to replace the function of the elastic member that is fixedly coupled to the other side of the elastic member that is applied to the upper side is installed on the support member 52 with the second elastic member 91 at the same time to rotate the rotational force and the lifting force with one rotary support 40 It is possible to have, there is an advantage that can simplify the configuration of the chair member by excluding the elastic member for applying the elastic force upward to the support member 52.

According to another embodiment of the present invention as described above when the user discharges the chair member 50 located inside the table top plate 100 to the outside of the table top plate 100, the first cutting groove 200 and the second cutting The spirally wound first elastic member 90 coupled to the groove 210 is wound, and the user sits downward on the seat plate 51 of the chair member 50 fixed to the other side of the connecting member 20. When the load is applied, the second elastic member 91 for applying an elastic force upwardly accommodated in the first space portion 41 of the rotation support 40 is compressed, so that the support member 52 is in close contact with the ground so that the user can sit. When the user stands up after use, the support member 52, which is in close contact with the ground, is spaced apart from the ground by the restoring force of the second elastic member 91 that has been compressed, and at the same time, the first elastic member 90 that has been wound is applied to the restoring force. Loosen by and fixedly coupled to the other side of the connecting member (20) Chair member 50 is returned to the inside of the table top plate 100
