Abstract
Abstract A lift recliner chair is provided also incorporating a rocker assembly including rocker structure mounted from the chair and floor engageable rocker plate structure rockably connected to the rocker structure, whereby the chair may be rocked back and forth relative to the rocker plate structure. However, inasmuch as the center of mass of a recliner chair and a person disposed thereon is appreciably rearwardly shifted relative to the chair base when the chair is in the recliner defining configuration, the chair is equipped with a downwardly extendable and upwardly retractable prop automatically shifted between the retracted and extended positions thereof as the chair is shifted between the chair defining and recliner defining configurations thereof. When the prop is in the downwardly extended position, it engages the floor from which the chair is supported rearward of the rocker assembly and in a manner to prevent rearward rocking of the chair relative to the rocker plate structure past the center position of rocking movement of the chair.

Claim 1
Independent Claim
330 words
In a lift chair having a lift base, guide means adjustably supporting said chair from said lift base and including force means connected between said lift base and chair to selectively raise and lower said chair with respect to said lift base, accessory base means supported from said chair and positioned to contact the floor before said lift base is fully raised relative to said chair so that full raising of said lift base relative to said chair elevates said lift base above the floor, said accessory base means including rocker assembly means incorporating rocker means mounted from said chair and floor engageable rocker plate disposed beneath and rockably connected to said rocker means for rockably supporting said rocker means and chair from said rocker plate means and thus the floor from which said rocker plate means is supported, whereby when said lift base is fully raised said chair will be supported from the floor by said accessory base means and be rockable relative to said floor, said chair comprising a recliner chair including a frame from which said rocker means of said rocker assembly means is supported, a seat portion supported from said frame, a back portion supported from said frame for swinging of said back portion between an upstanding position and a reclining position relative to said frame, and rear prop means shiftably supported from said frame and operatively connected to said back portion for downward extension and upward retraction of said prop means relative to said frame responsive to shifting of said back portion between said reclined and upstanding positions, respectively, said prop means, when extended downwardly relative to said frame, being engageable with said floor rearward of said rocker means to prevent rearward rocking of said frame when said back portion is in the reclined position thereof and when upwardly retracted being ineffective to engage said floor and thus ineffective to prevent rearward rocking of said frame when said back portion is in the upstanding position.
