Claims

[Scope of Claim for Utility Model Registration] Between the side pillars A arranged at appropriate intervals, there is provided a rectilinear movement mechanism C that maintains the foldable telescopic side B and the side pillar A in a fixed direction and achieves linear expansion and contraction, and a leg with wheels is provided at the bottom. An extendable door with a D. A mechanism in which the front side 3 and the rear piece 4, which have the same width and are bent in the middle, are attached to the side pillar A with the same surface spacing, and the bisectors of each angle formed by these two bent surfaces coincide and overlap. Straight moving mechanism C formed by applying
An extendable door according to claim 1 of the utility model registration claim using. Attach the front side 3 and the rear piece 4, which have the same width and are bent in the middle, to the side post A with the same spacing on both sides, and then assemble the supporting parts 7 equidistant from the support shaft 5, and the assembly equidistant from the support shaft 6. Fold both ends of the opening/closing pieces 9 and 10 of equal length to the branch 8 and connect the two supporting shafts 12 and 13 to the connecting piece 1.
1. An extendable door according to claim 1, which uses a linear movement mechanism C which is interlocked and connected. The extendable door according to claim 1, which is a registered utility model, in which a V- or W-shaped folding lattice piece 16 is provided between the side pillars A and used as a straight-advance mechanism C.
