The first and second rear pawl frames 130 and 140 are in contact with the first end and the second rear pawl frame 130 and 140, respectively, (210, 220) are formed.

On the other hand, the portable chair frame of the second embodiment may further include one or more third support members spaced rearward from the first and second support members 10, 20 and disposed on the ground.

The first embodiment of FIG. 1 shows that one third support member is formed, and the second embodiment of FIG. 5 shows that two third support members are formed. The number of the third support members can be variously changed according to a desired chair structure.

In the case of the second embodiment of Fig. 5, it includes two of the third support members 31, 33, one third support member 31 is located behind the first support member 10, And the other end of the first support frame 210 is detachably attached to the third support member 31 located at the rear of the third support member 33. [ And the other end of the second support frame 220 is detachably coupled to the third support member 33 located at the rear of the second support frame 220.

The backrest of the chair can be more stably supported by the two third supporting members 31 and 33 supported at the two points relative to the ground at the rear of the chair and can be stably supported can do.

The second central support frame 330 includes a first central support frame 310 connecting the first and second support members 10 and 20 and connecting the two third support members 31 and 33, ). Accordingly, since the support members are connected and supported by the first and second central support frames 310 and 330, even if the load of the user is excessively applied, the first and second support members 10 and 20 and the third support It is possible to prevent the members 31 and 33 from being spaced apart or from being displaced. It is possible to provide a rigid portable chair capable of withstanding a larger load.

The first and second armrest frames (110, 120) are connected to the first and second hubs (40, 50), respectively, and the other end is connected to the other end of the first and second front pole frames 410, 420). Since the first and second armrest frames 410 and 420 are further included, it is possible to provide a portable chair that can stably support the arm in use.

On the other hand, one end of each of the first and second armrest frames 410 and 420 may be rotatably connected to the first and second hubs 40 and 50. Accordingly, the first and second armrest frames 410 and 420 are rotated downward (in the direction of the paper surface) while being fixed to the first and second hubs 40 and 50, It can be fixed to the other end of the pole frames 110 and 120 or separated from the first and second front pole frames 110 and 120 by being rotated upwards (in the direction opposite to the ground). More specifically, one end of the first and second armrest frames 410 and 420 may be hinged to the bracket 41 extending from the first and second hubs 40 and 50.

6 is a partial enlarged view of the first hub 40. Referring to FIG. 6, a bracket 41 is extended forward of the first hub 40, and a first armrest frame 410 is extended, The hinge structure 43 or the hinge joint 43 passing through the hinge structure is coupled to the bracket 41. [ The first armrest frame 410 and the second armrest frame 420 are also formed in this manner so that the first and second armrest frames 410 and 420 are respectively disposed on the first and second hubs 40 and 50, And in the opposite direction to the ground. 6, the first and second armrest frames 410 and 420 are coupled to the first and second hubs 40 and 50 in a hinged manner. However, the present invention is not limited thereto, And the second hub 40, 50, as shown in FIG.

The other ends of the first and second armrest frames 410 and 420 may have first and second connecting members 60 and 70 for connecting to the first and second front pole frames 110 and 120, .

7A and 7B are partially enlarged views showing the first connecting member 60 in detail. Although the first connecting member 60 is described as a reference, the second connecting member 70 may be formed in the same manner.

7A, the first connecting member 60 includes a first housing 61 having an insertion hole H1 into which the other end of the first armrest frame 410 is inserted, a first front pawl frame 110, And a second housing 63 formed with a through hole H2 through which the other end of the second housing 63 passes. The first housing 61 is formed in such a manner that it is connected to the side surface of the second housing 63, and can be formed as an integral mold as in the embodiment of FIGS. 7A and 7B.

The first housing 61 may include an insertion hole H1 through which the first and second armrest frames 410 and 420 are inserted and a slot 65 formed in parallel with the insertion direction. The first armrest frame 410 may have a protrusion 411 at a position corresponding to the slot 65.

Accordingly, the protrusion 411 is formed so as to be movable along the slot 65. That is, the first linking member 60 and the first armrest frame 410 may be connected to each other in a variable position.

7A, since the first connecting member 60 is urged in a pulling direction from the first armrest frame 410, the protruding portion 411 is positioned in the slot 65 on the side of the frame for the armrest As shown in FIG. Thereby, the first connecting member 60 is connected with a minimum insertion depth D1.

7B, since the first connecting member 60 is urged in the pushing direction from the first armrest frame 410, the protruding portion 411 is positioned at the side of the connecting member in the slot 65 Thereby maintaining the coupling. Thereby, the first connecting member 60 is connected with a maximum insertion depth D2.

7A and 7B, the insertion depth of the first armrest frame 410 with respect to the first linking member 60 may vary depending on the direction of the applied force. That is, it can have a variable insertion depth between the minimum insertion depth D1 and the maximum insertion depth D2. The second housing 63 has a through hole H2 through which the first front pole frame 110 is inserted. The through hole H2 may be formed to have a diameter smaller than the diameter of the first and second front pole frames 110 and 120. The first and second front pole frames 110 and 120 have a diameter corresponding to the through hole H2 and the body portions 113 and 123 of the first and second front pole frames 110 and 120 The insertion portions 111 and 121 may be formed smaller than the diameter of the insertion portions 111 and 121, respectively.

Accordingly, the second housing 63 moves along the insertion portions 111 and 121 and is formed so as not to move beyond the body portions 113 and 123 of the first and second front pole frames 110 and 120 .

As a result, the first and second armrest frames 410 and 420 are rotatably coupled to the first and second hubs 40 and 50, and the first and second armrest frames 410 and 420 The first and second armrest frames 410 and 420 are inserted into the first and second connecting members 60 and 70 in a state in which the lengths of the insertion portions 111 and 121 Direction.

Fig. 8 is a side view showing a state in which the chair frames of the second embodiment are combined. Fig. 8 is a side view showing a state in which the seat cloth 90 is attached to the first and second front pole frames 110 And 120, respectively.

8, the lower portions of the armrest frames 410 and 420, the front pole frames 110 and 120, and the rear pole frames 130 and 140 will form a closed triangular structure in a coupled state. That is, in FIG. 8, a triangular structure connecting P1-P2-P3 is formed. 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.
