  • Patent number: 7475642
    Abstract: A table includes a table top and a table frame. The table frame preferably includes one or more side rails, end rails, table legs, and support braces. The table also includes a mounting structure that is provided on the underside of the table top. At least a portion of a support assembly is connected to the mounting structure. Desirably, the mounting structure and the support assembly are disposed towards the center portion of the table, but the mounting structure and/or support assembly could be located in any desired portion of the table. Preferably, one end of the support braces is pivotally attached to the support assembly and the other end is pivotally attached to a table leg. Advantageously, the support assembly provides a “planar” support area to a portion of the table top.

  • Patent number: 7278361
    Abstract: A folding table is disclosed having a two-stage folding mechanism. The folding table includes a table top divided into a first planar portion and a second planar portion. A pair of side rails is connected to each planar portion. A foldable leg and support brace is connected to each planar portion. A hinge assembly is provided disposed between the first planar portion and the second planar portion. The hinge assembly includes a hinge pin, a first hinge connector and a second hinge connector. The first hinge connector has a cam portion. A locking pin is disposed through a slot in the second hinge connector. A lock actuating mechanism may be used to move the locking pin in the slot between the locked and unlocked position. In one embodiment, the lock actuating mechanism includes a handle coupled to the locking pin and a spring biased against the locking pin.

  • Patent number: 7055899
    Abstract: A folding picnic table includes a foldable table top and two or more seats. The foldable table top is preferably supported by a table top supporting assembly that is movable between an extended position and a collapsible position. Advantageously, the table top supporting assembly can be stored in the foldable table top when the picnic table is in the collapsed position. Desirably, each seat is supported by a seat supporting assembly that is movable between an extended position and a collapsible position. Preferably the seat supporting assembly is stored in a seat when the picnic table is in the collapsed position. The table top supporting assembly can further be folded into a fully folded position when the table top is folded to further reduce the size and dimensions of the picnic table when the picnic table is in the collapsed position.

  • Publication number: 20040237855
    Abstract: Support structures are provided having an improved connecting structures. Support structures include tables, chairs, and the like. The improved connecting structures securely connect a support surface and a support leg. For example, the improved connecting structures of the present invention can be used to connect a table top to a table leg. In one embodiment, a table top has a raised portion extending from a bottom surface thereof. A connector having a horizontal portion and at least one vertical portion is secured to the raise portion. A table leg is then pivotally connected to the connector. The connector can be U-shaped or L-shaped. The length of the vertical portion of the connector is less than the height of the raised portion of the table top.

  • Publication number: 20040195869
    Abstract: A picnic table includes a table top with a pair of legs and a pair of benches or seat members with seat legs. The picnic table also includes a foot member with a generally C-shaped structure having a middle portion and two end portions. The middle portion of the foot member preferably includes connecting tubes that are selectively and slidably coupled to the table legs. The end portions of the foot member are preferably selectively and slidably coupled to the seat legs. In addition, the seat legs are desirably pivotably foldable to be stored in a storage space underneath the seat and the table legs are desirably pivotably foldable to be stored in a storage space underneath the table top.
