Abstract

A children'expandable, accordian-type gate is disclosed which includes safety features for closing off the open, upper V-shaped openings of the latticework of the gate, which latticework is comprised of a first series of slats parallel to each, and a second series of salts parallel to each other but angularly oriented differently from the first series. The upper V-shaped openings are closed off by upper extensions of the slats forming the boundaries of the V-shaped openings, which extensions project above the two, mutually-pivoted upper slat-ends from two adjacent V-shaped openings. The lower portions of the latticework of the gate may be positioned an approximate constant elevation above the floor or support above which it extends by the provision of sliding mounting brackets for the upper portions of the latticework which allow sliding movement thereof relative to the end posts, while the lower portions of the latticework are provided only with a pivot attachment that prevents such sliding movement relative to the end posts. Further, there may be provided a central leg brace or support for shoring up the center portions of the lattice-work, especially when extra-long gates are em…
