If the position of P3 is fixed, only the portion connecting P2-P4 of the rear pole frames 130, 140 should be bent and attached because the triangular structure portion is fixed in order to mount the seat cloth 90. [ A large amount of force is applied to move the sheet cloth 90 by moving only a part of the rear pawl frames 130 and 140 (P2 to P4).

However, in the second embodiment, since the armrest frames 410 and 420 can move in the longitudinal direction of the front pole frames 110 and 120 by a predetermined distance (indicated by the arrow R1), the triangular structure of P1-P2-P3 The part is not fixed. That is, since the movement is allowed even in a state where all the frames are combined, the entire frame can be moved without moving only the part P2-P4 of the rear pole frames 130 and 140, It can be easily mounted.

For example, the seat cloth 90 is first fitted on the upper portions of the rear pole frames 130 and 140, and the lower portions of the rear pole frames 130 and 140 and the front pole frames 110 and 120 are spaced apart from each other The front and rear pawl frames 110, 120, 130 and 140 are brought close to each other by applying a pushing force to the front pawl frames 110 and 120 in the directions of arrows f1 and f2, . In this case, since the positions of the rear pole frames 130 and 140 and the front pole frames 110 and 120 are slightly adjusted, it is possible to mount the seat cloth 90 with a relatively small force.

When the positions of the armrest frames 410 and 420 are fixed, much stress is applied to the hub, the supporting member, or the connecting member connecting the frames of the chair. Eventually, this will lead to the problem of the durability of the connection of the chair frames. However, in the case of this embodiment, the durability of the hub, the supporting member, or the connecting member connecting the frames can be increased by allowing the motion in the coupling of the frames to relax the stress.

On the other hand, Fig. 9 is for explaining assembly and disassembly of the portable chair frame of the second embodiment.

The chair frame is used in an assembled state as shown in Fig. 5, and can be folded separately for carrying and storing when not in use. 9, the first and second front pole frames 110 and 120 may be detachably coupled to the first and second support members 10 and 20 so as to be connected to the elastic string S. [

The first and second rear pole frames 130 and 140 may be formed of two or more unit frames 131, 133, 141, and 143. And may be detachably coupled to the first and second support members 10 and 20 and the first and second hubs 40 and 50 and may be connected by an elastic string S. [ More specifically, the upper unit frame 131 of the first rear pole frame 130 is detachably coupled to the lower unit frame 133 or the first hub 40, and may be connected to the elastic string S.

On the other hand, if all of them are detachably coupled, it is troublesome to separate all of the components and assemble them all. Therefore, some components may be kept connected if they do not affect folding for convenience of reassembly. In the present embodiment, the lower unit frame 133 and the first armrest frame 410 may be fixedly coupled to the first hub 40. Since the first armrest frame 410 is rotatably coupled, the first armrest frame 410 can be folded side by side with the lower unit frame 133 about the first hub 40.

However, it should be understood that the first armrest frame 410 and the lower unit frame 133 may be detachably or elastically connected to the first hub 40.

Meanwhile, the first and second support frames 210 and 220 may be detachably coupled to the first and second hubs 40 and 50, respectively. In this embodiment, the first and second support frames 210, 220 and the first and second hubs 40, 50 are not connected by an elastic string. Since the first and second hubs 40 and 50 are stored in a state in which many frames are connected to each other, they are stored separately from other frames. However, it is needless to say that the present invention is not necessarily limited thereto, but may be provided in connection with an elastic string.

The first central supporting frame 310 and the second central supporting frame 330 between the first and second supporting members 10 and 20 and the three third supporting members 31 and 33 are fixedly coupled . This is because there is no inconvenience of storage and carrying even if it is kept in a combined state. However, it should be understood that the first and second central support frames 310 and 330 and the support members may be detachably coupled to each other, and may be provided in connection with the elastic strands.

In the case of this embodiment, since it further includes the armrest frame, it has an advantage that it can provide more comfort in that the armrest can be provided when the user does not use it. In addition, it is possible to minimize the stress between the components while providing the armrest, thereby providing a portable chair frame excellent in durability. In addition, it is possible to provide a portable chair frame which is easy to assemble and store in use by detachably coupling components and connecting them with an elastic string for the convenience of assembly, storage and carrying.

The present invention is capable of various modifications and may have various other embodiments, and one embodiment has been illustrated and described in the drawings. It is to be understood, however, that it is not intended to limit the scope of the specific embodiments but includes all transformations, equivalents, and alternatives falling within the spirit and scope of the disclosure disclosed.
