  • Patent number: 6793279
    Abstract: A reclining seating unit includes: a generally horizontally disposed seat; a pair of upright arms, each of the arms being positioned adjacent opposite sides of the seat and configured to rest on an underlying surface; a generally upright backrest positioned adjacent to a rear portion of the seat; at least one ottoman; and a pair of reclining mechanisms attached to the seat, arms, backrest and at least one ottoman, and a heart-rest mechanism pivotally interconnected with the reclining mechanisms. The heart-rest mechanism is configured so that the seating unit is movable between fully reclined and heart-rest positions in which the ottoman is disposed forwardly of the seat, the backrest forms a fully reclined angle with the seat that is substantially the same as that formed in the fully reclined position, and the seat forms a heart-rest angle with the underlying surface that is greater than in the fully reclined position.

  • Patent number: 6648418
    Abstract: A collapsible footrest assembly for a gliding ottoman with a top structure gliding upon a base. A pair of parallel, elongated slides are movably mounted under the top structure between upper and lower positions with respect to the top structure. A footrest is slidably and pivotally mounted between the slides for sliding operation between a slide-in position wherein the footrest extends and is supported between the slides and a slide-out position wherein the footrest is drawn out and pivoted down in front of the slides. The slide arrangement is detachably hooked under the top structure in the upper position, and is detachably locked with the base when it is in the lower position to prevent the ottoman from gliding when the footrest is in use.

  • Patent number: 5775775
    Abstract: A reclining press-back seating unit utilizes modified three-way reclining mechanisms. The three-way mechanism is modified to be free of a footrest, and is mounted within the press-back seating unit so that its links are positioned in the upright position in the same orientation to one another that they would be in the TV position of the three-way reclining unit. The seating unit can be used with virtually any three-way reclining mechanism, including those for wall-avoiding units and high-leg units, to create pressback versions of these units which are particularly suitable for use in multiple seat seating units.

  • Patent number: 5562049
    Abstract: A table having a pair of laterally extendable table surfaces. The table includes a base having a horizontally disposed periphery that defines a footprint on an underlying surface, first and second generally planar table surfaces, a table surface forward extension mechanism interconnected with the base and the first and second table surfaces, and a table surface lateral extension mechanism interconnected with the base and the first and second table surfaces. The table surface forward extension mechanism and the table surface lateral extension mechanism are each constructed and arranged so that each of the first and second table surfaces is movable between a retracted position, in which the first and second table surfaces are positioned generally above the base footprint, and a laterally extended position, in which the major portions of the first and second table surfaces are generally horizontally disposed and are positioned above, forwardly and laterally of the base footprint.

  • Patent number: 5549052
    Abstract: Disclosed herein is a table comprising a base, a table surface, and a mechanism for controlling the movement of the table surface relative to the base. The table surface is movable between a retracted position, in which the table surface is generally horizontally disposed above and adjacent the base, and an extended position, in which the table surface is generally horizontally disposed above the base and a major portion of the table surface resides forwardly of the base. The mechanism is mounted to a table base and a table surface. The mechanism has a front pivot link, pivotally interconnected to the base at a first pivot, and a rear pivot link, pivotally interconnected to the base at a second pivot link. The mechanism is mounted to the surface at the upper portion of the front pivot link at a third pivot, and at the upper portion of the rear pivot link at a fourth pivot. The mechanism is configured such that it can be mounted inboard of the table base end panels.
