請求の範囲第1項記載の折りたたみ式の梯子。[Claims for Utility Model Registration] 1. A folding ladder characterized by comprising the following hinges, solid bars, horizontal foot bars, and connecting horizontal bars. B. The above hinge is made of a male hinge and a female hinge made of electrically insulating material, teeth that engage with each other are attached to the mutually facing surfaces of the two hinges, and a recessed groove is attached to the handle that is integrated with the hinge. The recessed tube wall of the hard rod fits into the recessed groove, and the hinge and hard rod are fixed and assembled together.In addition, a horizontal threaded rod is attached to the center of the teeth of the male hinge, and this screw The rod must have a left-handed or right-handed thread and extend through the shaft hole of the male hinge. (b) The above-mentioned solid rod constitutes the vertical legs of the ladder, and is fixed by having a vertical groove in the center and inserting it into the handle of the hinge. be assembled, and have screw holes and grooves so that both ends of the foot pedal horizontal bar fit into the grooves, and can be fixed by screwing into the screw holes. C. The above-mentioned horizontal foot treadle bar is assembled between two hard bars, both end surfaces of which fit well with the surfaces of the hard bars, and a tube with a circular hole is provided, and a thread is cut in the tube. , by screwing a screw into this tube from the outside of the solid rod to secure and assemble the two together. (d) The above-mentioned connecting horizontal rod connects two solid rods between the connected hinges, and the circular holes on both end faces have left-handed or right-handed threads, so that they can connect with the threaded rod of the hinge. If you screw them together and rotate them in one direction,
The hinges on both sides can be tightened or loosened. (e) Connect two adjacent solid bars with the above hinge to form one leg of this ladder, and install both legs symmetrically,
Assemble the connecting horizontal bar and the foot pedal horizontal bar in the middle, and fit the threaded rod of the hinge with the left and right threads at both ends of the connecting horizontal bar, and rotate the connecting horizontal bar in one direction. To tighten or loosen the threaded rod of a hinge at the same time. 2. When the hinge is loosened by rotating the connecting horizontal bar, the male and female teeth of the hinge are disengaged from each other, and the male and female hinges are rotated at an appropriate angle. A folding ladder as described in Scope 1. 3. The foldable ladder according to claim 1, wherein the hinge is made of non-conductive plastic material. 4 The screw hole provided in the hard rod is located exactly at the stop groove, and after assembling the foot pedal horizontal bar to the hard rod with the screw, insert a long and thin metal piece into the stop groove, and the screw will loosen and fall out. A folding ladder according to claim 1 of the claimed utility model registration, which prevents this from occurring.
