And in order to fold the first and second leg member connecting frames 10 and 20 inward, when the guide 52 is pushed up, the first and second leg member connecting frames 10 and 20 are folded and the protruding safety pin 71 is It exits from the hole (53).

The beam member connection frame 70 is configured with an upper end open in a cross-sectional form of "∪", and a space 72 capable of accommodating the beam member 300 is formed therein.

The beam member 300 accommodated in the space 72 of the beam member connection frame 70 is fixed to the beam member connection frame 70 through fastening means such as screws.

A sleeve 74 is installed at the lower end of one side of the beam member connection frame 70 . The sleeve 74 is fitted into the outer diameter of the shaft rod 64 whose ends are coupled to the first and second hinges passing through the first and second leg member connection frames 10 and 20 described above, and the first and second The leg member connection frames (10, 20) rotate with the shaft rod (64) as a starting point to enable folding and unfolding of the beam member connection frame (70).

That is, when the beam member connection frame 70 surrounding the beam member 300 is spread outward by the first and second leg member connection frames 10 and 20, the first and second pressing plates 60 and 62 are the beam members. The outer side of the connection frame 70 is pressed and held, and the sleeve 74 of the beam member connection frame 70 is supported by the connecting rod 34 together with it.

When storing the first and second leg members 200 and 210 installed at the lower ends of both sides of the beam member 300 by using the connecting device of the present invention, the first and second leg members with the shaft rod 64 as a starting point When the connection frames 10 and 20 are rotated, the first and second leg members 200 and 210 are horizontally folded and can be folded under the beam member 300 supported by the beam member connection frame 70 , It is not necessary to separate the beam member 300 and the first and second leg members 200 and 210, and can be stored in a reduced volume state.

On the other hand, the first and second leg member connection frames (10, 20) are not assembled in a vertically standing state at the lower end of the beam member connection frame (70), but are inclined at a predetermined angle (A) in the outward direction. Support the member connection frame.

To this end, a groove portion 36 is recessed in the upper portion of the connecting rod 34 connecting the ends of the first and second hinges 30 and 32 , and the beam member is connected to the groove portion 36 of the connecting rod 34 . When one end of the bottom surface 71 of the frame 70 comes into contact, the first and second leg member connection frames 10 and 20 are connected to the beam member connection frame 70 by the depth of the groove portion 36 as shown in FIG. 7 . ) may be arranged to be inclined at a predetermined angle (A) in the outward direction, and the inclined angle of the first and second leg member connection frames (10, 20) is the first to apply the load transmitted from the beam member connection frame (70). , the two-legged member connection frame (10, 20) can be supported more stably.

Hereinafter, the operation of the connecting device for connecting the leg member and the beam member of the present invention configured as described above will be described.

First, when connecting the first and second leg members 200 and 210 and the beam member 300 using the connecting device of the present invention, the space of the first and second leg member connecting frames 10 and 20 of the connecting device After inserting the first and second leg members 200 and 210 into the (12, 22), respectively, the first and second inserted into the spaces 12 and 22 of the first and second leg member connecting frames 10 and 20 The leg members 200 and 210 are fastened and fixed with the first and second bolts 14 and 24 .

Next, in a state in which the beam member 300 is inserted into the space 72 of the beam member connection frame 70, the first and second bolts 14 and 24 are fastened to the beam member 300 as well as the beam member connection frame 70. fasten to the

Next, when the first and second leg members 200 and 210 are held and unfolded to the outside, the first and second leg member connection frames 10 and 20 rotate around the first and second hinges 60 and 62, The first and second links 42 and 44 and the guides 52 connected with the connecting links 50 between the first and second leg member connecting frames 10 and 20 are unfolded outward. Moving up and down on the guide rod 54 fixedly installed on the connecting rod 34 coupled to the first and second hinges 60 and 62, the first and second leg member connecting frames 10 and 20 are unfolded outside. to make this happen stably.

Next, when the first and second leg member connecting frames (10, 20) are spread out, the first and second pressing plates (60) installed inside the upper ends of the first and second leg member connecting frames (10, 20) , 62) is engraved inward according to the outer unfolding operation of the first and second leg member connecting frames 10 and 20, and presses the outer surfaces of both sides of the beam member connecting frame 70 to connect the beam member connecting frame 70. is pressed and fixed to the first and second leg member connection frames (10, 20).

After the first and second leg members 10 and 20 are connected to the lower end of one side of the beam member connecting frame 70 in the same manner as above, the first, second leg members 10, 20 are also connected to the lower end of the other side of the beam member connecting frame 70 in the same manner. By connecting the two leg members 10 and 20, a support structure composed of a leg member and a beam member having a shape as shown in FIG. 2 is completed.

The support structure completed as described above can be used as a pedestal for supporting the work die as shown in FIGS. 9 and 10, and can also be used as a support means for supporting a swing, which is a play equipment, as shown in FIG. As in 12, it can also be used as a blocking facility such as prohibition of entry.

On the other hand, when you want to store a support structure made of a leg member and a beam member, the first and second leg members 200 and 210 can be folded down to the beam member 300 to reduce the volume.

That is, when the first and second leg members 200 and 210 are pushed in the inward direction of the beam member 300 while holding the first and second leg members 200 and 210 as in FIGS. 8 and 13A to 13D, the first and second leg member connection frames 10, The shaft rod 64 connected to the ends of the first and second hinges 60 and 62 of 20) rotates while being fitted in the sleeve 74 installed at the lower end of the beam member connection frame 70, and thus Accordingly, the first and second leg members 200 and 210 can be folded under the beam member 300, so that it is not necessary to separate the beam member and the leg member of the support structure, and can be stored in a reduced volume.
