Abstract

A changeable frame for supporting flat surfaced items such as pictures, posters, placards or the like, is provided, which includes a plurality of frame border strips which collectively form the border of the changeable frame. Each frame border strip includes a base profile member and a cover member movable between a closed item retaining position in which an item is retained by the changeable frame and the cover member partially extends over and exerts a resilient biasing force against the item and an open position. Each frame border strip also includes a pivot arrangement for pivotally mounting the base profile member and the cover member to one another. The pivot arrangement includes a fulcrum formed on the base profile member which is contacted by a counter stop surface formed on the cover member to prevent an overpivot movement of the cover member beyond its predetermined pivot travel.
