Quick manual lock for display frames |
摘要 |
A display frame is formed by a number of collapsible, articulated structural sections movable between a stable erect configuration and a collapsed configuration. Four pairs of scissored links are connected to exterior pivots at their ends to form the exterior of each structural 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 to a face pivot. A through-extending opening is provided in one face pivot, and a locking component is associated with 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.
