Claims

[Scope of Claim for Utility Model Registration] 1. A link mechanism consisting of a large number of diagonal bars that are mutually connected with two or more stages in the vertical direction, with vertical bars pivoted at appropriate link bending portions and appropriate link crossing portions of the link mechanism. This is a gate that is expandable and retractable, with only the bending part of the link and the crossing part of the link that do not move up and down relative to the vertical frame as it expands and contracts, fixedly pivoted vertically by a fixed pivot, And 2 from the end
A diagonal bar in which both the second and third vertical bars are fixedly pivoted by fixed pivots is configured to be bendable about the fixed pivot of the second vertical bar, and the outer end of the diagonal bar is at the outermost end. A telescoping gate characterized by being pivotally attached to the vertical crosspiece by a movable pivot that can move up and down. 2. The telescoping gate according to claim 1 of the utility model registration claim, which has a bendable bending angle regulating means.
