Abstract
An improved dual leg rest assembly is disclosed which is adapted for use in single and multi-person articles of furniture (i.e., chairs, sectionals, sofas, loveseats, etc.). More particularly, an improved linkage mechanism is provided for causing coordinated articulating movement of a primary leg rest panel and a secondary leg rest panel (i.e., mid-ottoman) which as disclosed, also includes a selectable height ottoman.
Claims20
In an article of furniture having a seat assembly supported from a chair frame and an actuation mechanism for enabling a leg rest assembly to move between a stowed position and an extended position, said leg rest assembly comprising:
- a primary leg rest panel;
- a secondary leg rest panel;
- and
- linkage means interconnecting said primary and secondary leg rest panels to the actuation mechanism for coordinated articulated movement such that in said stowed position said secondary leg rest panel is oriented behind and in general parallelism with said primary leg rest panel so as to be concealed thereby, and in said extended position said primary and secondary leg panels are oriented so as to provide a substantial continuous and uninterrupted support surface with said seat assembly, said linkage means including a first linkage for causing articulated movement of said primary leg rest panel and a second linkage for causing articulated movement of said secondary leg rest panel, and wherein said second linkage is supported on said first linkage for movement in response to movement of said first linkage;
- said first linkage comprising first and second board links pivotally connected to said primary leg rest panel, a first connector link pivotally interconnecting said first board link to said chair frame, a second connector link pivotally interconnecting said second board link to a first end of a support link, and a drive link interconnecting the actuation mechanism to a second end of said support link, said first connector link being pivotably interconnected to an intermediate portion of said support link and said second connector link being pivotally interconnected to an intermediate portion of said first board link;
- said second linkage comprising a third board link having a first portion on which said secondary leg rest panel is secured, a second portion pivotally interconnected to said first board link and a third portion pivotably interconnected to a third connector link, said third board link including height selection means;
- said first board link having height selection means for pivotally securing said third board link;
- and
- said third connector link pivotally coupled to said second connector link at a first end and pivotally secured to said height selection means of said third board link at a second end.

- said second linkage comprising a third board link having a top flange to which said secondary leg rest panel is secured, an intermediate portion pivotably secured to said first board link, and a lower lobe having an upper aperture and a lower aperture formed therein, one of said upper and lower apertures pivotably secured to a third connector link;
- said first board link having an upper aperture and a lower aperture formed therein, one of said upper and lower apertures for pivotably securing said third board link;
- said third connector link pivotally coupled to said second connector link at a first end and pivotally secured to one of said upper and lower apertures of said third board link at a second end;
- and
- a cover secured to said secondary leg rest panel.
