Each of the above-described configurations will be described in detail below.

Referring to Figures 1 and 2,

The left hub 100 and the right hub 200 are opposed to each other and each have a central frame 300, a rear frame 400, a front frame 500, and a leg frame 600, Is formed.

The center frame 300 is formed in the shape of a hollow tube having an inner hollow portion and one end is coupled to the left hub 100 and the other end is coupled to the right hub 200 to connect the left hub 100 and the right hub 200 So that the left and right hubs 100 and 200 are positioned horizontally.

The rear frame 400 is formed in the shape of a hollow tube having an inner hollow portion. The left and right hubs 200 and 200 are formed in a configuration for forming a backrest framework in a double frame camping chair according to an embodiment of the present invention. One end of each of which is coupled to the other end, and the other end extends obliquely upward.

The front frame 500 is formed in the form of a hollow tube having an inner hollow and forms a skeleton of a seating portion for supporting the buttocks of a seated person in a double frame camping chair according to an embodiment of the present invention. One end of each of the left hub 100 and the right hub 200 is coupled to each other, and the other end of the left hub 100 and the right hub 200 are forwardly extended to form a predetermined inclination.

It is to be understood that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof.

FIG. 3 is a cross-sectional view of a leg frame of a chair for a double frame camping according to an embodiment of the present invention, FIG. 4a is a side view of the leg frame of the double frame camping chair according to an embodiment of the present invention, FIG. 4B is a partially cutaway perspective view showing a state in which a leg frame of a chair for a double frame camping according to an embodiment of the present invention is provided with reinforcing protrusions on the outer frame portion and the inner frame portion, and FIG. Is a perspective view showing that a supporting portion is formed on a leg frame of a chair for a double frame camping according to an embodiment of the present invention.

In one embodiment of the present invention, the leg frame 600 is formed of a hollow tube with four hollow inner sides, one end coupled to the left hub 100 and the right hub 200, The other end is extended.

Preferably, one end is coupled to the left hub 100 and the other end is extended toward the ground. The other end extends forward and rearward so that the other ends thereof are distant from each other. This is also the case with the right hub 200.

Since the leg frame 600 radially extends from the left and right hubs 100 and 200 toward the ground, the other end abuts against the ground and supports the load of the double frame camping chair according to one embodiment of the present invention, And effectively disperses the load exerted on the base plate 600.

At this time, the leg frame 600 is formed by joining the outer frame portion 610 and the inner frame portion 620 to secure rigidity against the load.

The outer frame portion 610 and the inner frame portion 620 are formed of hollow tubes whose inner sides are hollow and whose inner diameter is equal to or smaller than the inner diameter of the outer frame portion 610 . This allows the inner frame portion 620 to be inserted into the inside of the outer frame portion 610.

As shown in FIG. 3, since the leg frame 600 to support the load of the seated person is overlapped and overlapped with the outer frame portion 610 and the inner frame portion 620, resistance against bending is increased, So as to have higher durability against load or repetitive fatigue load.

At this time, as shown in FIGS. 4A and 4B,

An inner reinforcing protrusion 621 formed to protrude in the longitudinal direction toward the outer periphery is formed on the outer periphery of the inner frame portion 620. When the inner frame portion 620 is inserted into the outer frame portion 610, 610).

Since the inner reinforcing protrusion 621 is formed at the outer periphery of the inner frame portion 620, the rigidity against the bending of the inner frame portion 620 is increased, and the inner diameter of the inner frame portion 620 is reduced So that it is possible to save the material for forming the inner frame part 620 and to achieve the weight reduction effect.

The outer reinforcing protrusion 611 is formed by protruding inwardly from the inner periphery of the outer frame portion 610 in the longitudinal direction and the inner reinforcing protrusion 611 and the inner reinforcing protrusion 621, As shown in the cross-sectional view of FIG. This prevents the inner frame portion 620 and the outer frame portion 610 from loosing each other when engaged.

The outer reinforcing protrusion 611 serves to increase the rigidity of the entire leg frame 600 together with the inner reinforcing protrusions 621 and to reduce the inner diameter of the inner frame portion 620 by the height of the protrusion, So that the protruded volume is not large.

The support portion 622 shown in FIG. 5 is formed in a plate shape extending outward from the lower end of the leg frame 600, specifically, the lower end portion of the inner frame portion 620.

This is because the double frame camping chair according to an embodiment of the present invention has a problem that when the lower end of the leg frame 600, which is in contact with the ground in an environment where the ground is not stable like a sandy beach, This allows a double frame camping chair according to an embodiment of the present invention to be mounted on a ground such as a sandy beach by widening the contact area with the ground.

The support piece 630 is fitted to a lower end portion of the leg frame 600 contacting the ground surface, thereby preventing the lower end portion of the leg frame 600 from being damaged and being stably mounted on the ground.

The elastic string 700 passes through the empty inner side of the central frame 300, the rear frame 400, the front frame 500 and the leg frame 600 as described above and is connected to the left hub 100, the right hub 200, And the support pieces 630 are connected so that the respective frames are constrained.

All of the configurations of the double frame camping chairs according to one embodiment of the present invention are connected by the elastic string 700 so that the loss of some configurations can be prevented, The position is guided and the time is saved.

The seat 800 is preferably formed of a fabric and is joined to the ends of the respective front and rear frames 500 and 400 to form a seat and a back which the user can sit on and lean on.

The operation of the double frame camping chair according to one embodiment of the present invention will be described based on the above-described structure.

The left hub 100 and the right hub 200 are positioned and coupled to both ends of the center frame 300 and the two leg frames 600 of the four leg frames 600 are positioned below the left hub 100 In the front and rear directions. The two leg frames 600 are coupled to the right hub 200 in the same manner as in the left hub 100.

The front frame 500 and the rear frame 400 are coupled to the left and right hubs 100 and 200 while the lower ends of the leg frame 600 radially coupled toward the ground face the ground.

The seat 800 is coupled to the ends of the front frame 500 and the rear frame 400 coupled with the left and right hubs 100 and 200 to assemble the seat 800 so that the user can sit there.
