Abstract
On a spring-assisted handle-operated rocker recliner, each side linkage is provided with a forward and a rear landing gear. On each side, the links on which the contact elements (such as rollers) are mounted, are pivoted at intermediate locations on each, to the main flange of the respective side linkage. The ends nearest to the middle of the respective rocker cam are both pivoted to a set of links that, in effect, pull up those ends as the handle, and therefore the torque tube, is rotated to thrust the ottoman, and to push down those ends as the torque tube is rotated to retract the ottoman. The flange on each side linkage is provided with slots, which are enlarged at one end for facilitating mounting the flange on the respective rocker cam.
Claims15
A rocker lock for a spring-assisted, handle-operated rocker recliner in which left and right rocker cams of a rocker cam frame of a rockable chair assembly are supported for rocking forwardly and rearwardly respectively on upwardly presented running surfaces of left and right rails of a base of the recliner, the rockable chair assembly further including a motion chair mechanism mounted to and supported on the rocker cam frame and including left and right side linkages which are coordinately interconnected by a transversely extending torque tube that is journalled for reversible rotation about a longitudinal axis of the torque tube, the torque tube having a handle secured on one end thereof for effecting manual rotation of the torque tube, an upholstered seat and arm frame unit mounted at corresponding sites to the left and right side linkages, an upholstered chair back mounted at corresponding sites to the left and right side linkages, and an upholstered ottoman mounted at corresponding sites to the left and right side linkages, the mechanism being operable by rotation of the handle in a first direction when the recliner is in a closed, fully erect position, to fully extend the ottoman to achieve an intermediate position of said recliner, and being operable when the ottoman is so-extended, by a user's leaning back on an upper portion of the chair back, to fully recline the chair back, being operable when the chair back is fully reclined by the user's concentrating their weight downward on a seat portion of the seat and arm frame unit, to erect the chair back, and being operable by rotation of the handle in a second direction which is opposite to said first direction, to fully retract the ottoman,
- said rocker lock comprising:
- a left lock structure and a right lock structure which are mirror image constructions relative to one another, each of said left and right lock structures including a forward landing link pivotally mounted to the respective side linkage of the rocker chair assembly for rotation between an inactive position wherein a forward end of said forward landing link is spaced above the respective running surface of the respective rail of said base so that said rockable chair assembly is free to rock forwardly, and an active position wherein the forward end of said forward landing link is urged firmly against the respective running surface of the respective rail of said base so that said rockable chair assembly is prevented from rocking forwardly, and each of said left and right lock structures further including a rear landing link pivotally mounted to the respective side linkage of the rocker chair assembly for rotation between an inactive position wherein a rear end of said rear landing link is spaced above the respective running surface of the respective rail of said base so that said rockable chair assembly is free to rock rearwardly, and an active position wherein the rear end of said rear landing link is urged firmly against the respective running surface of the respective rail of said base so that said rockable chair assembly is prevented from rocking rearwardly.
A spring-assisted, handle-operated rocker recliner in which left and right rocker cams of a rocker cam frame of a rockable chair assembly are supported for rocking forwardly and rearwardly respectively on upwardly presented running surfaces of left and right rails of a base of the recliner, the rockable chair assembly comprising:
- a motion chair mechanism mounted to and supported on the rocker cam frame and including left and right side linkages which are coordinately interconnected by a transversely extending torque tube that is journalled for reversible rotation about a longitudinal axis of the torque tube, the torque tube having a handle secured on one end thereof for effecting manual rotation of the torque tube;
- an upholstered seat and arm frame unit mounted at corresponding sites to the left and right side linkages;
- an upholstered chair back mounted at corresponding sites to the left and right side linkages;
- and
- an upholstered ottoman mounted at corresponding sites to the left and right side linkages,
- the mechanism being operable by rotation of the handle in a first direction when the recliner is in a closed, fully erect position, to fully extend the ottoman to achieve an intermediate position of said recliner, and being operable when the ottoman is so-extended, by a user's leaning back on an upper portion of the chair back, to fully recline the chair back, being operable when the chair back is fully reclined by the user's concentrating the user's weight downward on a seat portion of the seat and arm frame unit, to erect the chair back, and being operable by rotation of the handle in a second direction which is opposite to said first direction, to fully retract the ottoman;
- and
- a rocker lock including a left lock structure and a right lock structure which are mirror image constructions relative to one another, each of said left and right lock structures including:
- a forward landing link pivotally mounted to the respective side linkage of the rocker chair assembly for rotation between (1) an inactive position wherein a forward end of said forward landing link is spaced above the respective running surface of the respective rail of said base so that said rockable chair assembly is free to rock forwardly, and (2) an active position wherein the forward end of said forward landing link is urged firmly against the respective running surface of the respective rail of said base so that said rockable chair assembly is prevented from rocking forwardly, and
- a rear landing link pivotally mounted to the respective side linkage of the rocker chair assembly for rotation between (1) an inactive position wherein a rear end of said rear landing link is spaced above the respective running surface of the respective rail of said base so that said rockable chair assembly is free to rock rearwardly, and (2) an active position wherein the rear end of said rear landing link is urged firmly against the respective running surface of the respective rail of said base so that said rockable chair assembly is prevented from rocking rearwardly.
A rocker lock for a rocker recliner having a rockable chair assembly supported for rocking forwardly and rearwardly on upwardly presented running surfaces of a base of the recliner, said rocker lock comprising:
- a left lock structure and a right lock structure, each of said left and right lock structures including:
- a forward landing link pivotally mountable to the rockable chair assembly for rotation between (1) an inactive position wherein a forward end of said forward landing link is spaced above the respective running surface of said base so that said rockable chair assembly is free to rock forwardly, and (2) an active position wherein the forward end of said forward landing link is urged firmly against the respective running surface of said base so that said rockable chair assembly is prevented from rocking forwardly, and
- a rear landing link pivotally mountable to the rockable chair assembly for rotation between (1) an inactive position wherein a rear end of said rear landing link is spaced above the respective running surface of said base so that said rockable chair assembly is free to rock rearwardly, and (2) an active position wherein the rear end of said rear landing link is urged firmly against the respective running surface of said base so that said rockable chair assembly is prevented from rocking rearwardly.
