[36] One end of the body 10 is formed as an opening part 12, and a hinge hole 14 is formed at the other side. One end of the load tube 20 is formed as an opening part 22, and the end is inserted to the inside of the body 10 through the opening part 12 of the body 10. A hinge hole 24 is formed at the other end of the load tube 20. A hook 16 is formed on the end of the opening part 12 of the body 10 along the circumference at regular intervals, and a mounting portion 18 whose diameter has been extended is formed in such a manner that a ring stopper 50 and a guide stopper 60 are able to be safely landed inside of the opening part 12.

[37] A guide cap 40, the ring stopper 50, and the guide stopper 60 are combined in order in the load tube 20.

[38] On the guide cap 40, a hook 16 formed on the opening part 12 of the body 10 is combined to the guide cap 40 and a hook hole 42 is formed on the guide cap 40 with a hook 16 in a corresponding way, in which the hook hole 42 keeps the load tube 20 from being separated from the body 10.

[39] The ring stopper 50 and the guide stopper 60 are made of rubber materials, whereby the ring stopper 50 generates friction force that prevents the trembling when the supporter is operated, and the guide stopper 60 generates friction force when the load tube 20 is tensioned. In the preferred embodiment of the present invention, there are three ring stoppers 50, but the number of the ring stoppers 50 does not need to be limited three, and the number can be increased or decreased depending on the size of the friction force to be generated.

[40] Such a ring stopper 50 and a guide stopper 60 are placed at the inside of the mounting portion 18 of the body.

[41] Furthermore, a cutting part 26 is formed at the right and left sides in the opening part 22 of the load tube, and a raised part 28 is formed, whereby the separation of the guide cap 40, the ring stopper 50, and the guide stopper 60 is prevented.

[42] A rotation bracket 70 for fixing the other part of the body 10 in the hinge hole 14 formed at the other side of the body is locked by a stopper pin 90.

[43] A boss 76 for fixing the pin is formed at the center of the plate 72 in which a screw- locking hole 74 formed at both sides of the rotation bracket 70, and a reinforcement rib 78 is formed to both sides of the boss 76.

[44] Eye bracket 80 for fixing the other side of the load tube 20 is formed at the hinge hole 24 of the load tube 20, and is locked by the stopper pin 90.

[45] A hinge 86 is formed in the Eye bracket 80, in which a pin-fixing hole 88 is formed at both sides of the plate 82 in which the screw-locking hole 84 is formed at both sides.

[46] The stopper pin 90 is formed by a head 92 and a body 94, and several suspending hooks 96 are diverged and extended at the lower part of the body 94.

[47] A coil spring 30 is included in the lid supporter, which elastically supports the load tube 20 on the body 10 through the hollow of the body 10 and the hollow of the load tube 20 and the present invention excludes the sealing of gas or oil, and the operating force of the lid supporter is generated by the elastic force of the coil spring.

[48] The elements of the present invention are made of plastic materials excluding a few parts such as the coil spring 30, the ring stopper 50, and the guide stopper 60.

[49] Such plastic is made of recyclable resin, for example, thermoplastic resins such as polypropylene and polyamide, or thermosetting resins such as phenol and epoxy. Further, such resins can be manufactured by the combination of more than two kinds of ingredients. The bending or deformation of the supporter can be prevented by manufacturing a material, which is the combination of glass fiber, carbon fiber, and a reinforcement material, an aromatic nylon fiber such as Kevlar.

[50] The assembling process and the operation by the lid supporter according to the present invention are described in the following.

[51] A guide cap 40, a ring stopper50, and a guide stopper 60 are mounted on the outer c ircumference of the load tube 20 in order. Here, the parts are inserted by folding the opening part 22 of the load tube by the cutting part 26 formed at the opening part 22 of the load tube 20, and after the parts are all inserted, the separation of parts is prevented by the raised part 28 formed at the end of the opening part 22 as the opening part 22 is unfolded.

[52] Furthermore, if the hook 16 formed at the end of the opening part 12 of the body 10 is hook-combined to the hook hole 42 of the guide cap 40 mounted on the load tube 20, the load tube 20 is not separated in the combined state in such a manner that the sliding is mutually possible.

[53] Another side of each of the body 10 and the load tube 20 are locked to a bracket 70 and 80 via a stopper pin 90 in a hinge hole 14 and 24 of each. That is, the body 10 is locked by the rotation bracket 70 and the stopper pin 90, and the load tube 20 is locked by the eye bracket 80 and the stopper pin 90. The stopper pin 90 locked by the rotation bracket 70 is locked in the state where the raised part of the suspending hook 76 of the stopper pin 90 that penetrates the plate 72 supports the lower side of the plate 72. Furthermore, the stopper pin 90 locked by the eye bracket 80 is locked in the state where the raised part of the suspending hook 76 supports the side wall of the hinge of one side as the stopper pin 90 penetrates the pin-fixing hole 88 of the hinges 86 of both sides.

[54] As for the operation of the lid supporter 100 whose assembly has been completed, in the state where external force is given, the load tube 20 is taken in and out by the tensioning and compressing operation of the coil spring 30 on the body 10.

[55] FIG. 3 illustrates the state where the load tube is taken out, and FIG. 4 is a sectional view illustrating the state where the load tube is taken in on the body.

[56] That is, if external force is given to the body 10, the load tube 20 is taken into the inside of the hollow of the body 10, and the coil spring 30 is compressed. If the external force is removed, the load tube 20 that has been taken into the inside of the hollow of the body 10 is taken out into the outside of the body 10 by the expansion of the coil spring 30, whereby the supporting operation is performed.
