Aspects of this disclosure relate to chair reclining mechanisms. More particularly, this disclosure includes embodiments relating to an extendable ottoman linkage having a split pad configuration with a release linkage.
Chairs today are often equipped with an ottoman, or a split ottoman, that extends from the front of a chair to support a user's feet and lower legs. The split ottoman is extended from a stowed position, typically in a vertical orientation directly below the front edge of the seat, to an extended position, typically in a horizontal orientation extending outwardly from the front edge of the seat. The movement of the split ottoman is controlled by a linkage to move from the stowed position to the extended position. This linkage can be manually operated, or motorized, to move between the stowed and extended positions. As the linkage moves from the extended to the stowed position, there exists a possibility that some object may move into the path of the closing linkage. This can be problematic, especially on motorized mechanisms. What is needed is an ottoman or split ottoman linkage that provides some type of release mechanism to address a situation where the path of the linkage encounters an object creating an entrapment.
The present disclosure generally relates to a split ottoman linkage having a plurality of interconnected links that move a middle ottoman and a front ottoman from a closed position to an extended position. The middle ottoman and the front ottoman are positioned adjacent one another in the closed position, and are spaced from one another in the extended position. The linkage includes a release mechanism that operates to provide relief if the linkage experiences an entrapment as the linkage moves from the extended position to the closed position.
Accordingly, in one embodiment, a split ottoman linkage for a reclining chair mechanism on a chair having a frame, a seat, and a backrest is provided. The split ottoman linkage includes a front ottoman link having first and second ends, the first end is coupled to an upper ottoman link of a reclining chair mechanism. The split ottoman linkage also includes a middle ottoman link having first and second ends, the first end being coupled to a lower ottoman link of the reclining chair mechanism and the middle ottoman link is coupled to the upper ottoman link near the first end. The split ottoman linkage further includes an upper ottoman bracket coupled to the second end of the middle ottoman link and near the second end of the front ottoman link, the middle ottoman link and upper ottoman bracket are adapted to extend the upper ottoman bracket in a relatively constant radial arc. Additionally, the split ottoman linkage includes a front ottoman bracket coupled to the second end of the front ottoman link; and a coupling link coupled between the upper ottoman bracket and the front ottoman bracket. The split ottoman linkage is adapted to move between a closed position with the upper ottoman bracket and the front ottoman bracket positioned close to one another, and an extended position where the upper ottoman bracket and the front ottoman bracket are spaced from one another. The upper ottoman bracket has a slotted coupling arrangement between it and the front ottoman link. This slotted arrangement provides a relief system if any of the upper ottoman bracket, the coupling link, the front ottoman bracket (or an ottoman board attached to the front ottoman bracket) encounter an object creating an entrapment.
In another embodiment, a split ottoman linkage for a reclining chair mechanism on a chair having a frame, a seat, and a backrest is provided. The split ottoman linkage includes a front ottoman link having first and second ends, the first end being coupled to an upper ottoman link of a reclining chair mechanism. The split ottoman linkage also includes a middle ottoman link having first and second ends, the first end being coupled to a lower ottoman link of the reclining chair mechanism. The middle ottoman link is coupled to the upper ottoman link at an upper ottoman link connection point that is closer to the first end than the second end of the middle ottoman link. Additionally, the split ottoman linkage includes an upper ottoman bracket coupled to the second end of the middle ottoman link, the upper ottoman bracket being coupled to the front ottoman link at an upper ottoman bracket connection point that is closer to the second end than the first end of the front ottoman link. The middle ottoman link and the upper ottoman bracket are adapted to extend the upper ottoman bracket in a relatively constant radial arc when the split ottoman linkage is shifted between a closed position and an extended position. The split ottoman linkage further includes a front ottoman bracket having first and second ends, the first end being coupled to the second end of the front ottoman link at a front ottoman bracket connection point. The upper ottoman bracket has a slotted coupling arrangement between it and the front ottoman link. This slotted arrangement provides a relief system if any of the upper ottoman bracket, the coupling link, the front ottoman bracket (or an ottoman board attached to the front ottoman bracket) encounter an object creating an entrapment.
In yet another embodiment, a chair having a reclining mechanism is provided. The chair includes a frame, a seat pad, a seat back, and a split ottoman linkage adapted for use with a reclining mechanism. The split ottoman linkage includes a front ottoman link having first and second ends, the first end is coupled to an upper ottoman link of a reclining chair mechanism. The split ottoman linkage also includes a middle ottoman link having first and second ends, the first end being coupled to a lower ottoman link of the reclining chair mechanism and the middle ottoman link is coupled to the upper ottoman link near the first end. The split ottoman linkage further includes an upper ottoman bracket coupled to the second end of the middle ottoman link and near the second end of the front ottoman link, the middle ottoman link and upper ottoman bracket are adapted to extend the upper ottoman bracket in a relatively constant radial arc. Additionally, the split ottoman linkage includes a front ottoman bracket coupled to the second end of the front ottoman link; and a coupling link coupled between the upper ottoman bracket and the front ottoman bracket. The split ottoman linkage is adapted to move between a closed position with the upper ottoman bracket and the front ottoman bracket positioned close to one another, and an extended position where the upper ottoman bracket and the front ottoman bracket are spaced from one another. The upper ottoman bracket has a slotted coupling arrangement between it and the front ottoman link. This slotted arrangement provides a relief system if any of the upper ottoman bracket, the coupling link, the front ottoman bracket (or an ottoman board attached to the front ottoman bracket) encounter an object creating an entrapment.
