Abstract
A folding table includes a table top and a frame. The frame includes side rails hinged together at a table folding axis so the table can be moved between a folded and an opened position. The table includes a latch to secure the table in the opened position. The table includes frame end reinforcement portions including bights extending between opposite frame side rails near the table top ends. The table includes a handle that is movable between a stowed and a carrying position, the handle being pivotable about a portion of a frame member.
Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates to a folding table and particularly to a folding banquet table having two table top end portions that can fold between an opened table position having top surfaces of the table top end portions aligned in coplanar relation to form a large table surface and a collapsed or folded position having the table top end portions folded together.




Tables having two table sections coupled together for pivoting movement between an opened table position and a folded collapsed position are well known. Conventional folding tables typically include table legs that can fold against the table sections allowing the table sections to be folded together without interference from the table legs. See, for example, U.S. Pat. No. 5,445,085 to Westerburgen; U.S. Pat. No. 5,421,272 to Wilmore; U.S. Pat. No. 5,357,872 to Wilmore; U.S. Pat. No. 3,368,504 to Cohen; and U.S. Pat. No. 2,542,394 to Cohen et al, the disclosures of which are hereby incorporated by reference herein.




In the present application, a folding table is provided comprising a table top having opposite ends and a hinged tubular frame coupled to the table top. The table includes a frame having a handle pivotable about a frame member and movable between a carrying position extending from the table top and a stowed position adjacent the table top. The table includes a latching mechanism to automatically and releasably latch the frame to secure the table in the opened position. The table includes a frame having end reinforcement sections.




In the illustrative embodiment, the frame includes opposite side rails, a pair of rotatable pivot bars or cross members and a pair of bar mounts or sleeves to pivotably receive the pivot bars. The frame includes two end-reinforcing portions each portion having a bight coupled to the ends of two U-shaped frame members or pivot supports. The pivot bars and the pivot supports are connected end-to-end to form a loop. Each pivot bar is coupled to each pivot support so that each pivot bar can rotate inside each pivot support. Each end of each pivot bar is inserted into one of the sleeves of each pivot support for rotation. Each leg unit is coupled to one of the pivot bars so that each leg unit can swing back and forth when the respective pivot bar rotates.




The table includes a handle pivotably or rotatably coupled to a portion of the frame. The handle is movable between a carrying position and a stowed position. In the stowed position, the handle lies in a recess formed in the downwardly facing surface of the table top.




The frame and table top further include first and second portions coupled by a pair of hinges allowing a user to fold the table in half. The table includes a releasable latch that automatically latches the table in an unfolded or opened position when a user moves the table from the folded position to the opened position. To fold the table, a user manually unlatches the latch and folds the downwardly facing surface of one half or portion of the table top and frame toward the other.




Additional features of the present invention will become apparent to those skilled in the art upon consideration of the following detailed description of the invention exemplifying the best mode of carrying out the invention as presently perceived.

between the collapsed position and the extended position shown in FIG.


2


.




Left-side leg unit


22


includes first and second legs


158


,


160

188


of first and second links


182


,


184


locks leg units


20


,


22


in the extended position, as shown in

. Illustratively, in the extended position, each leg unit


20


,


22


forms an angle


190


of 92 degrees measured from downwardly facing surface


16


of table top


12


in the direction each leg unit


20


,


22


pivots away from the collapsed position toward the extended position. Moving sliding ring


186


from junction


188


permits respective leg units


20


,


22


to pivot from the opened position back to the collapsed position.




Table


10


includes a handle


230


movable between a carrying position shown in

FIGS. 2 and 5

and a stowed position as shown in FIG.


7


. Handle


230


is pivotably or rotatably coupled to first side rail


40


and includes a coupler


232


, first and second arms


234


,


236


coupled thereto, and a hand grip


238


coupled to and extending between the arms. When handle


230


is assembled, as shown in

FIG. 5

, coupler


232


includes first and second generally tubular-shaped portions


240


,


242


sized to receive first side rail


38


.




Each of first and second tubular portions


240


,


242


of handle


230


include front and rear recesses


244


,


246


as shown in

FIGS. 4-7

. As best shown in

FIG. 2

, bottom surface


16


of table top


12


includes a handle receiver


248


sized to receive handle


230


in a stowed position and two spaced-apart notches


250


,


252


sized to receive arms


234


,


236


when handle


230


is in its carrying position. As shown in

FIGS. 5-7

, notches


250


,


252


each include complementary portions, illustratively detents


254


, positioned to lie in one of the front or rear recesses


244


,


246


when handle


230


is in its stowed or carrying position respectively.




When handle


230


is in its carrying position, as shown in

FIG. 5

, detents


254


engage rear recesses


246


of coupler


232


, releasably securing handle


230


in the carrying position. When handle


230


is in its stowed position, as shown in

FIG. 7

, detents


254


engage front recesses


244


of coupler


232


, releasably securing handle


230


in the stowed position. Because of the engagement of the detents and the recesses, tubular portions


240


,


242


of the handle do not move freely about one of first or second pivot supports


46


,


48


, yet a user may apply minimal force to move the handle away from the stowed or carrying position.




As shown in

FIGS. 5-7

, as a user moves handle


230


from the stowed position toward the carrying position, detents


254


disengage second engagement surfaces or edges


282


of front recesses


244


of coupler


232


. As the user continues to move the handle, the detents


254


and portions of notches are deformed as shown in FIG.


6


and outer surface


260


of tubular portions


240


,


242


slides against detents


254
