LOCKABLE DISPLAY FRAME ABSTRACT A collapsible, articulated structural section (of a frame) which is movable between a stable erect configuration and a collapsed configuration includes a manually actuable positive lock for locking the device in its erect configuration. Four pairs of scissored links connected to exterior pivots at their ends form the exterior of the section, and the interior is formed by a pair of face pivots and four pairs of crossed, but unconnected, face links, each pivotally connected at one end thereof to an exterior pivot and at the other end thereof to a face pivot. For most of the structural sections of a frame, a through- extending opening is provided in one face pivot, and a locking component including a shaft portion insertable into the opening, and a rotatable locking member mounted on the end of the shaft, are mounted on the other face pivot. One of the structural sections of the frame has as the locking component a cam follower member which during movement of the face pivots towards each other is cammed by a linear cam associated with the through-extending opening, and then snaps to lock in place.
