Gliding mechanism for a gliding recliner seating assembly

摘要

A gliding mechanism for a gliding recliner seating assembly comprises a floor-standing base having a longitudinal cross member parallel to a width of the seating assembly. Two front connecting links and two back connecting links respectively connect, pivotally, front and back portions of the seating assembly to the floor-standing base. The longitudinal cross member supports a weight transferred by the seating assembly to the floor-standing base and is positioned closer to the back portion of the seating assembly than to the front portion of the seating assembly. The gliding mechanism can be made part of a gliding recliner chair, for example an armchair, having vertical side frames pivotally connected to the floor-standing base. A footrest can be added to the seating assembly and be operated in extended position without preventing gliding movement of the chair. The floor-standing base may comprise a pivoting portion allowing rotation of the chair.

主权项

1. A gliding mechanism for mounting to a gliding recliner seating assembly, the gliding mechanism comprising:
a floor-standing base comprising a floor-engaging portion defining a planar perimeter having a longitudinal dimension configured for placement in a direction of a gliding movement of the seating assembly and having a longitudinal cross member configured for placement in parallel to a width of the seating assembly, the longitudinal cross member being configured for supporting a weight transferred by the seating assembly to the floor-standing base when the gliding mechanism is mounted to the seating assembly, the weight transferred by the seating assembly to the floor-standing base comprising a weight of the seating assembly alone or a combined weight of the seating assembly and of a user sitting on the seating assembly; and two front connecting links and two back connecting links configured for, respectively, pivotally connecting front and back portions of the seating assembly to the floor-standing base so that the longitudinal cross member is positioned closer to the back portion of the seating assembly than to the front portion of the seating assembly when the gliding mechanism is mounted to the seating assembly; wherein a normal projection of a center of gravity of the weight supported by the longitudinal cross member lies within the planar perimeter, generally spaced from the planar perimeter by a distance of at least about 15% of the longitudinal dimension at any position of the gliding movement.
