A folding sectional table assembly includes a pair of table sections, each of which includes a frame assembly and a table top. Each frame assembly includes inner and outer leg assemblies, and each leg assembly has an upper tubular member pivotably mounted at its ends relative to a pair of apron members secured to the underside of the table top, for providing pivoting movement of the leg assembly relative to the table top. A torsion bar assist mechanism is disposed within selected ones of the upper tubular members of the leg assemblies, and includes a torsion bar located within an internal passage defined by the upper tubular member. At one end, the torsion bar is engaged with a torsion bar retainer mounted to a hub arrangement which also functions to pivotably mount one end of the upper tubular member. A torsion bar driver is mounted within the internal passage of the upper tubular member at a location spaced from the torsion bar retainer, for twisting the torsion bar during relative pivoting movement between the table top and the leg assembly as the table sections are lowered to an unfolded, operative position. One or more pneumatic cylinder assemblies are mounted to an inner leg assembly of each table section, and are interconnected at one end with the leg assembly and at an opposite end with a hinge pin which pivotably interconnects a pair of hinge plates, with each hinge plate being mounted to one of the table sections for pivotably interconnecting the table sections. The pneumatic cylinder assembly functions to cushion the table sections as the table sections are lowered to the unfolded, operative position, and are especially advantageous for heavy table sections such as those which include seating. The pneumatic cylinder assemblies are spring biased toward an extended position, to also provide an assist in lifting the table sections when the table sections are moved away from the unfolded, operative position toward a folded, storage position. A latch arrangement selectively maintains the table sections in the folded, storage position, and includes a latch member pivotably mounted to one of the table sections and a catch member stationarily mounted to the other of the table sections. A latch actuator is interconnected between the latch member and the apron members, for disengaging the latch member from the catch member when it is desired to move the table sections away from the folded, storage position. The latch actuator includes an actuator area located adjacent each side of the table assembly, for enabling an operator to easily access the actuator member for disengaging the latch member without having to reach between the table sections when in the folded, storage position.
In a folding table assembly including first and second table sections, each of which defines an inner end and an outer end, wherein the table sections are pivotably interconnected at their inner ends for movement of the table assembly between a folded, storage position and an unfolded, operative position, wherein each table section includes a table top and a frame for supporting the table top above a support surface, the improvement comprising:
In a folding table assembly including first and second table sections, each of which defines an inner end and an outer end, wherein the table sections are pivotably interconnected at their inner ends for movement of the table assembly between a folded, storage position and an unfolded, operative position, wherein each table section includes a table top and a frame including a pair of spaced apart structural apron members mounted to the table top and a leg arrangement for supporting the table top above a supporting surface, the improvement comprising a torsion bar arrangement interconnected with the frame for assisting in movement of the table assembly from the unfolded, operative position to the folded, storage position, wherein the torsion bar arrangement includes a torsion bar defining a pair of spaced ends, and a pair of hub members mounted one to each structural apron member of at least one of the table sections, wherein each hub member is fixed to one of the apron members and wherein the leg arrangement is pivotably mounted to and between the hub members, wherein the torsion bar is fixed against rotation to one of the hub members and at a location spaced therefrom is fixed against rotation to the leg arrangement, wherein torque is imparted to the torsion bar as the table assembly is moved from the folded, inoperative position toward the unfolded, operative position.
In a folding table assembly including first and second table sections, each of which defines an inner end and an outer end, wherein the table sections are pivotably interconnected at their inner ends for movement of the table assembly between a folded, storage position and an unfolded, operative position, wherein each table section includes a table top and a frame for supporting the table top above a supporting surface, the improvement comprising at least one pair of pivoting hinge members, each hinge member of the pair of hinge members being mounted to one of the table sections, and an extendible and retractable cylinder assembly defining a first end interconnected with the pair of pivoting hinge members and a second end interconnected with a leg arrangement forming a part of the frame, wherein the leg arrangement is pivotable relative to the table top upon movement of the table assembly between its unfolded, operative position and its folded, storage position, wherein pivoting movement of the leg arrangement relative to the table top functions to move the cylinder assembly between an extended position and a retracted position, wherein the cylinder assembly is operable to cushion movement of the table assembly as the table assembly approaches its unfolded, operative position from its folded, storage position.
A latch arrangement for a folding table assembly including first and second table sections, each of which defines an inner end and an outer end, wherein the table sections are pivotably interconnected at their inner ends for movement of the table assembly between a folded, storage position and an unfolded, operative position, wherein each table section includes a table top and a frame including a leg arrangement for supporting the table top above a supporting surface, comprising:
In a folding table assembly including first and second table sections, each of which defines an inner end and an outer end, wherein the table sections are pivotably interconnected at their inner ends for movement of the table assembly between a folded, storage position and an unfolded, operative position, wherein each table section includes a table top defining a pair of spaced sides, and a frame for supporting the table top above a supporting surface, the improvement comprising:
