Abstract
A motorized positioning apparatus for a seating unit includes a motor assembly that is configured to move a pair of linkage mechanisms though a series of positions that arrange the seating unit in a closed position, open position, or extended position. The motor assembly is selectively and releasably coupled to the linkage mechanisms, to allow the motor assembly to be de-coupled from the linkage mechanisms to allow the seating unit to be manually closed by a user.
Claims20
A motorized positioning apparatus for a seating unit, the apparatus comprising:
- a pair of substantially mirror-image linkage mechanisms having a plurality of links controlling movement of an ottoman;
- a stationary rail coupled between the pair of linkage mechanisms;
- a motor tube coupled to at least one of the plurality of links of each linkage mechanism;
- a motor assembly comprising a body coupled to the stationary rail and a drive block slidably traversing the body;
- and
- a means for selectively and releasably coupling the drive block to the motor tube.
A motorized positioning apparatus for a seating unit, the apparatus comprising:
- a pair of substantially mirror-image linkage mechanisms having a plurality of links controlling movement of an ottoman;
- a stationary rail coupled between the pair of linkage mechanisms;
- a motor tube coupled to at least one of the plurality of links of each linkage mechanism;
- a motor assembly comprising a body coupled to the stationary rail and a drive block slidably traversing the body, the drive block comprising a pair of mounting tabs, each mounting tab of the pair of mounting tabs comprising an aperture;
- a back plate coupled to the motor tube comprising a pair of adjustment slots;
- and
- a pair of solenoid brackets coupled to the back plate by the pair of adjustment slots, wherein engaging the pair of solenoid brackets actuates a pair of pins receivable by the aperture of each mounting tab to selectively and releasably couple the motor tube to the drive block.
A motorized positioning apparatus for a seating unit, the apparatus comprising:
- a pair of substantially mirror-image linkage mechanisms having a plurality of links controlling movement of an ottoman, a backrest, and a seat;
- a rear base rail coupled between the pair of linkage mechanisms;
- a motor tube coupled to at least one of the plurality of links of each linkage mechanism;
- a motor assembly comprising a body coupled to the rear base rail, a drive block, a pair of mounting tabs wherein each mounting tab of the pair of mounting tabs comprises an aperture, and a motor coupled to the drive block to slidably move the drive block along the body;
- a back plate coupled to the motor tube comprising an opening to receive the body and slidably move the back plate along the body moving the motor tube and the pair of mirror-image linkage mechanisms controlling movement of the seat, the ottoman, and the back;
- a pair of solenoid brackets coupled to the back plate, wherein engaging the pair of solenoid brackets actuates a pair of pins to be received by the aperture of each mounting tab;
- and
- a controller to receive an input and wherein the input received engages the pair of solenoid brackets to actuate the pair of pins from a selectively coupled state to a releasably coupled state for the the motor tube to the drive block.
