Abstract
Abstract A folding table having a modesty panel employs a locking mechanism in the form of tab and hook assemblies to rigidify the table in the unfolded operative condition with the legs erect and the modesty panel in a position for use. The tab and hook assemblies are mounted on the panel and the tabs are received in slots in the adjacent leg assemblies to prevent hinged movement of the leg assemblies about their hinge axis. The hooks are rotatably and slidably supported in apertures in the tabs and are movable between a folded position and a leg embracing position. In the leg embracing position the hooks secure the tabs in the slots by preventing hinged movement of the panel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
229 words
A table having a top with a longitudinal X axis and a transverse Y axis said table having ends and sides, leg assemblies hingedly connected to said top adjacent the ends thereof for pivotal movement about a Y axis between folded and unfolded positions, a side panel hingedly connected to a side edge of said table for movement about the X axis between a folded and unfolded position, and means for connecting said panel to said leg assemblies to maintain the leg assemblies and panel in the unfolded erect position, said means including an opening in each leg assembly open along the Y axis and facing laterally outwardly of the top along the Y axis, projections on said panel registrable with said leg openings when the panel and leg assemblies are in the unfolded position, said projections preventing movement of said leg assemblies about said hinged connection to the top, said means further including hooks shiftable along the X axis between a leg clearance position and a leg embracing position with said hooks preventing movement of said panel to the unfolded position and disengagement of the projections when said hooks are in the leg embracing position, and wherein said hooks are supported in apertures in said projections and said hooks are rotatable about an axis parallel to the X axis to afford folding of the hook against the panel.
Claim 2
Dependent Claim
229 words
A table having a top with a longitudinal X axis and a transverse Y axis said table having ends and sides, leg assemblies hingedly connected to said top adjacent the ends thereof for pivotal movement about a Y axis between folded and unfolded positions, a side panel hingedly connected to a side edge of said table for movement about the X axis between a folded and unfolded position, and means for connecting said panel to said leg assemblies to maintain the leg assemblies and panel in the unfolded erect position, said means including an opening in each leg assembly open along the Y axis and facing laterally outwardly of the top along the Y axis, projections on said panel registrable with said leg openings when the panel and leg assemblies are in the unfolded position, said projections preventing movement of said leg assemblies about said hinged connection to the top, said means further including hooks shiftable along the X axis between a leg clearance position and a leg embracing position with said hooks preventing movement of said panel to the unfolded position and disengagement of the projections when said hooks are in the leg embracing position, and wherein said hooks are supported in apertures in said projections and said hooks are rotatable about an axis parallel to the X axis to afford folding of the hook against the panel.
Claim 3
Dependent Claim
19 words
A table in accordance with claim 1 including biasing means to urge said hooks to the leg embracing position.
Claim 4
Dependent Claim
190 words
A table having a top with ends and sides, leg assemblies hingedly connected to said top adjacent the ends thereof for pivotal movement between folded and unfolded positions, a side panel hingedly connected to a side edge of said table for movement between a folded and unfolded position, and means for connecting said panel to said leg assemblies to maintain the leg assemblies and panel in the unfolded erect position, said means including an opening in each leg assembly facing laterally outwardly of the top and facing the panel, projections on said panel registrable with said leg openings when the panel and leg assemblies are in the unfolded position, said projections preventing movement of said leg assemblies about said hinged connection to the top, said means further including hooks on said panel and shiftable between a leg clearance position in a plane parallel with the side panel and a leg embracing position with said hooks extending transverse to said panel locking said legs to said panel and preventing movement of said panel to the unfolded position and disengagement of the projections when said hooks are in the leg embracing position.
Claim 5
Dependent Claim
190 words
A table having a top with ends and sides, leg assemblies hingedly connected to said top adjacent the ends thereof for pivotal movement between folded and unfolded positions, a side panel hingedly connected to a side edge of said table for movement between a folded and unfolded position, and means for connecting said panel to said leg assemblies to maintain the leg assemblies and panel in the unfolded erect position, said means including an opening in each leg assembly facing laterally outwardly of the top and facing the panel, projections on said panel registrable with said leg openings when the panel and leg assemblies are in the unfolded position, said projections preventing movement of said leg assemblies about said hinged connection to the top, said means further including hooks on said panel and shiftable between a leg clearance position in a plane parallel with the side panel and a leg embracing position with said hooks extending transverse to said panel locking said legs to said panel and preventing movement of said panel to the unfolded position and disengagement of the projections when said hooks are in the leg embracing position.
