Making it possible.
[0015]
A coupling guide part 32 forming a jaw part 31 is formed in a semicircular shape at the upper end of the coupling projection 30, and a stopper for limiting the rotation angle of the ring part 16 is provided around the coupling projection 30. I have.
In the figure, reference numeral 6 denotes a multipurpose net for storage, and 7, 17, and 27 each denote a support for a folding leg.
[0016]
An operation state of the embodiment configured as described above will be described.
The table 1 and the folding chair can be separated and stored, and can be easily connected to each other according to the needs of the user.
[0017]
That is, the coupling projections 30 formed at the upper and lower ends of the rear vertical support legs 4 'supporting the table 1 and the upper and lower ends of the backrest posts 14, 24 of the folding chair corresponding to the coupling projections 30 are provided. By connecting the formed loop portions 16 to each other, the folding chair and the table 1 can have an integrated structure.
At this time, since the ring 16 has a shape with one side opened and has a predetermined elasticity, the ring-like shape is widely opened by the hemispherical connection guide 32 during the connection, and the connection protrusion 30 is formed. After being erected, it is supported by the jaws 31 while being prevented from coming off.
[0018]
FIG. 5 is a cross-sectional view showing a state in which the coupling between the loop portion 16 and the coupling protrusion 30 has been completed.
By such a simple joining operation, the joining between the table and the folding chair can be made as shown in FIG.
[0019]
On the other hand, in the case of a person with a large figure, the folding chair is coupled so close to the table 7 in the arrangement state as shown in FIG. 1 that the user may feel inconvenience when sitting on the chair.
In this case, as shown in FIG. 4, if the chair is rotated about the joint portion, the folding chair and the table 1 are kept in a state where the joint state between the loop portion 16 and the joint protrusion 30 is maintained. It can be seen that the space with is expanding and you can relax more.
[0020]
If the space where the product is provided is narrow, or if two people face each other across the table 1, the chair can be used by disposing the foldable chair from the table 1 and then arranging the chair. become.
[0021]
That is, when the folding chair is to be completely separated from the table 1, if the rotation angle of the chair is turned by 60 ° or more, one end of the ring portion 16 that has been connected to the connection protrusion 30 is turned on. The folding chair can be separated from the table 1 by being naturally separated from the coupling projection 30 while being pressed by the stopper 33 of the coupling portion.
[0022]
Therefore, according to the present invention, not only the connection between the folding chair and the table but also the separation can be easily performed, and as another application example of the present invention, the table is rotated with the folding chair completely separated. If it is made to warp backward, it will be understood that the storing net 6 appears and can be used for putting a ball in tennis or storing laundry in the room.

FIG. 6 shows a structure of a coupling member according to another embodiment of the present invention.
That is, connecting brackets 40 are provided at the upper and lower ends of the backrest posts 14, 24, respectively, and the connecting brackets 40 are detachably attached to the vertical supports 4 'on the rear side of the table 7 corresponding to the backrest posts 14, 24. A coupling groove 41, a rotation guide 42 eccentrically mounted on one side of the coupling groove 41, a locking portion 43 for limiting a rotation angle of the coupling bracket 40, and a guide for guiding a rotation path of the coupling bracket 40. A guide groove 45 and a detachable handle 44 having a support pin 44a formed at a tip thereof so as to rotate along with the rotation of the coupling bracket 4 along the guide groove 45 while receiving a restoring force of a coil spring 46 as an elastic member. ing.
[0024]
The operation relationship of the coupling member according to the other embodiment is as follows.
If the detachable handle 44 is rotated in the direction B, the eccentrically coupled rotation guides 42 rotate together to enlarge the coupling groove 41. In this state, the hand is removed from the detachable handle 44 after the coupling bracket 40 is pushed in. The coupling brackets 40 are prevented from coming off by the normal position of the rotary guide 42 while returning in the direction A by the restoring force of the coil spring 46, and are coupled to each other.
[0025]
When the folding chair is rotated about the fastening portion in the state of being connected in this way, the state in which the connection bracket 40 integrally connected to the backrest posts 14 and 24 of the chair is connected to the connection groove 41 is obtained. By pivoting along the guide groove 45 while maintaining, an extra space is created between the chair and the table 7. At this time, the coupling bracket 40 pivots while pressing the support pin 44a, so that the detachable handle 44 is moved. Rotate together.
[0026]
When the rotation angle of the folding chair exceeds 60 °, the chair is separated from the table 7 as in the above-described embodiment.
That is, when the rotation is performed at an angle of 60 ° or more, the side end of the coupling bracket 40 that has been rotated along the guide groove 45 is locked by the locking portion 43, and at this time, the rotation is performed. Since the rotation guide 42 is also eccentrically rotated by the detachable handle 44, the coupling groove 41 is enlarged, so that the coupling bracket 30 can be separated from the coupling groove 41 using the locking portion 43 as a support shaft.
[0027]
Therefore, it can be seen that the detachable structure of the other embodiment can easily perform the coupling and detachment operation between the table and the folding chair.
Although the specific embodiment of the present invention has been described above, it is needless to say that the detachable structure of the folding chair of the present invention can be variously modified and implemented by those skilled in the art.
