Definitions

  • the present invention relates broadly to motion upholstery furniture designed to support a user's body in an essentially seated disposition.
  • Motion upholstery furniture includes recliners, incliners, sofas, love seats, sectionals, theater seating, traditional chairs, and chairs with a moveable seat portion, such furniture pieces being referred to herein generally as "seating units.”
  • the present invention relates to an improved linkage mechanism developed to accommodate a seating unit that acts as a rocker or a glider recliner. Accordingly, the improved linkage mechanism of the present invention provides for reclining the seating unit while accommodating operation of a rocker mechanism or a glider assembly.
  • Reclining seating units exist that allow a user to forwardly extend a footrest or ottoman and to recline a backrest relative to a seat.
  • These existing seating units typically provide three basic positions: a standard, non-reclined closed position; an extended position; and a reclined position.
  • the closed position the seat resides in a generally horizontal orientation and the backrest is disposed substantially upright.
  • the seating unit includes an ottoman attached with a mechanical arrangement, the mechanical arrangement is collapsed such that the ottoman is not extended.
  • the extended position often referred to as a television (“TV”) position
  • the ottoman is extended forward of the seat, and the backrest remains sufficiently upright to permit comfortable television viewing by an occupant of the seating unit.
  • the reclined position the backrest is positioned rearward from the extended position into an obtuse relationship with the seat for lounging or sleeping.
  • rocker and glider recliners presently in the industry are adapted to provide the adjustment capability described above.
  • these recliners require relatively complex linkage mechanisms to afford this capability.
  • the complex linkage assemblies limit certain design aspects utilized by furniture manufacturers, such as incorporation of a motor to provide powered adjustment.
  • these present recliner linkage assemblies impose constraints on attaching a motor that can achieve full adjustment between the three positions above without interfering with internal crossbeams or limiting movement of the rocker mechanism or the glider assembly.
  • the present invention introduces a novel linkage mechanism that allows a rocker-recliner-style or a glider-style-recliner seating unit to provide the features of full powered adjustment between the three positions above without interfering with crossbeams or the operation of the rocker mechanism or the glider assembly.
  • Reclining seating unit is known from US 2003/0047973 A1 .
  • Embodiments of the present invention seek to provide a simplified, compact, linkage mechanism which can fully adjust a rocker-recliner-type seating unit (hereinafter “rocker recliner”) or a glider-recliner-type seating unit (hereinafter “glider recliner”) between three positions (closed, extended, and reclined) without limiting movement of a rocker mechanism or a glide assembly, respectively.
  • rocker recliner rocker-recliner-type seating unit
  • glider glider-recliner-type seating unit
  • the rocker/glider recliner is powered by a linear actuator that assists adjustment of a linkage mechanism. Movement of the linear actuator is sequenced into a first phase and a second phase, where the second phase occurs once the first phase is substantially complete. In other words, a stroke of the first phase is carried out substantially independently of a stroke of the second phase.
  • the first phase acts to adjust the linkage mechanism between the closed and extended positions
  • the second phase acts to adjust the linkage mechanism between the extended and reclined positions. Accordingly, in operation, the sequencing ensures that a footrest is substantially extended before a backrest begins reclining.
  • the simplified linkage mechanism discussed above can be assembled to a linear actuator reassembling a compact motor and that is adaptable to essentially any type of seating unit.
  • the compact motor in concert with the linkage mechanism can achieve full, sequenced, and automated adjustment of the rocker/glider recliner between each of the closed, extended, and reclined positions.
  • the compact motor may be employed in a proficient and cost-effective manner to adjust the linkage mechanism without creating interference or other disadvantages appearing in the conventional designs that are inherent with automation.
  • FIGS. 1-3 illustrate a seating unit 10.
  • Seating unit 10 has a seat 15, a backrest 25, legs 26 (e.g., support bushings), a linkage mechanism 100 or 1000, a first foot-support ottoman 45, a second foot-support ottoman 47, a stationary base 35, and a pair of opposed arms 55.
  • Stationary base 35 has a forward section 52, a rearward section 54, and is supported by the legs 26, where the legs 26 (e.g., bushings) support the stationary base 35 and raise it above an underlying surface (not shown).
  • the stationary base 35 is interconnected to the ,seat 15 via the linkage mechanism 100 or 1000 that is generally disposed between the pair of opposed arms 55, and the rearward section 54.
  • Seat 15 is moveable over the stationary base 35 during adjustment of the seating unit 10, when swaying a rocker mechanism of the linkage mechanism 100, or when oscillating a glide assembly of the linkage mechanism 1000.
  • the seat 15 or the backrest 25 is moveable according to the arrangement of the linkage mechanism 100 or 1000 such that no portion of the seat 15 interferes with the opposed arms 55 throughout adjustment.
  • Opposed arms 55 are laterally spaced and have an arm-support surface 57 that is typically substantially horizontal.
  • the pair of opposed arms 55 are attached to the stationary base 35 via intervening members.
  • the backrest 25 extends from the rearward section 54 of the stationary base 35 and is rotatably coupled to the linkage mechanism 100 or 1000, typically proximate to the arm-support surface 57.
  • First foot-support ottoman 45 and the second foot-support ottoman 47 are moveably supported by the linkage mechanism 100 or 1000.
  • Each linkage mechanism 100 and 1000 is arranged to articulably actuate and control movement of the seat 15, the back 25, and the ottomans 45 and 47 between the positions shown in FIGS. 1-3 , as more fully described below.

  • the seat 15 is disposed in a slightly inclined orientation relative to the stationary base 35. In this embodiment, the inclined orientation may be maintained throughout adjustment of the seating unit 10.
  • the ottomans 45 and 47 are positioned below the seat 15.
  • the extended position 30, or TV position will now be described.
  • the first foot-support ottoman 45 and the second foot-support ottoman 47 are extended forward of the forward section 52 of the stationary base 35 and disposed generally horizontal.
  • the backrest 25 remains substantially perpendicular to the seat 15 and will not encroach an adjacent wall.
  • the seat 15 is maintained in the inclined orientation relative to the stationary base 35.
  • the seat 15 is translated slightly forward and upward relative to the stationary base 35.
  • This independent movement of the seat 15 allows for a variety of styling to be incorporated into the seat 15, such as T-cushion styling.
  • FIG. 3 depicts the reclined position 40, in which the seating unit 10 is fully reclined.
  • the opposed arms 55 are attached to the stationary base 35 and the legs 26 extend from the stationary base 35.
  • the backrest 25 is rotated rearward by the linkage mechanism 100 or 1000 and biased in a rearward inclination angle.
  • the rearward inclination angle is typically an obtuse angle in relation to the seat 15.
  • the rearward inclination angle of the backrest 25 is offset by a forward and upward translation of the seat 15 as controlled by the linkage mechanism 100 or 1000.
  • the forward and upward translation of the seat 15 in embodiments of the present invention allow for zero-wall clearance.
  • the "zero-wall clearance" is utilized herein to refer to space-saving utility that permits positioning the seating unit 10 in close proximity to an adjacent rear wall and other fixed objects.
  • the ottomans 45 and 47 may be moved farther forward and upward from their position in the extended position 30.
  • FIGS. 4-7 illustrate the exemplary configurations of the linkage mechanism 100 for a rocker-recliner-type seating unit (hereinafter "rocker recliner) that is powered by a linear actuator included within a motor assembly 300.
  • the linkage mechanism 100 is arranged to articulably actuate and control movement of a seat, a backrest, and ottoman(s) of the rocker recliner when the linkage mechanism 100 is adjusted between the positions shown in FIGS. 5-7 . That is, the linkage mechanism 100 is adjustable to three basic positions: reclined position ( FIGS. 5 and 8 ), an extended (TV) position ( FIG. 6 ), and a closed position ( FIG. 7 ). In the reclined position, as shown in FIGS.

  • linkage when a linkage is referred to as being pivotably “coupled” to, “interconnected” with, “attached” on, etc., another element (e.g., linkage, bracket, frame, and the like), it is contemplated that the linkage and elements may be in direct contact with each other, or other elements (such as intervening elements) may also be present.
  • the linkage mechanism 100 guides the rotational movement of the backrest, the translation of the seat, and the extension of the ottoman(s). In an exemplary configuration, these movements are controlled by a pair of essentially mirror-image linkage mechanisms (one of which is shown herein and indicated by reference numeral 100), which comprise an arrangement of pivotably interconnected linkages.
  • the linkage mechanisms are typically disposed in opposing-facing relation about a longitudinally-extending plane that bisects the rocker recliner between the pair of opposed arms.

  • the seat-mounting plate 400 is configured to fixedly mount to the seat of the rocker recliner, and, in conjunction with an opposed seat-mounting plate, defines a seat support surface (not shown).
  • the seat-adjustment assembly 500 is adapted to recline and incline the backrest of the rocker recliner, which is coupled to the back-mounting link 510. Further, the seat-adjustment assembly 500 includes links (e.g., the motor bellcrank 430) that indirectly couple an activator bar 350 of a motor assembly 300 to the seat-mounting plate 400, thereby facilitating movement of the rocker-recliner seat in response to actuation of a linear actuator within the motor assembly 300.

  • the motor activator block 340 is attached to the activator bar 350 between the opposed ends by way of fasteners.
  • the motor mechanism 320 and the motor activator block 340 cause the motor activator block 340 to longitudinally traverse, or slide, along the track 330.
  • This sliding action produces a lateral force or thrust on the front motor tube 310 and the activator bar 350, which, in turn, generates movement of the linkage mechanism 100.
  • the sliding action of the motor activator block 340, or stroke of the linear actuator is sequenced into a first phase and a second phase.

  • the first phase involves longitudinal translation of the motor activator block 340 along the first travel section 331 of the track 330 that creates a lateral thrust at the front motor tube 310.
  • the lateral thrust invokes movement of the front ottoman link 110.
  • the movement of the front ottoman link 110 invokes and controls adjustment of the footrest assembly 200 between the closed position and the extended position.
  • the motor mechanism 320 moves forward and upward with respect to the rocker mechanism 410 while the motor activator block 340 remains generally fixed in space, thereby extending the footrest assembly 200 from the closed position to the extended position.
  • the second phase involves longitudinal translation of the motor activator block 340 along the second travel section 332 of the track 330 that creates a lateral thrust at the activator bar 350.
  • the lateral thrust invokes movement of the motor bellcrank 430.
  • the movement of the motor bellcrank 430 invokes and controls adjustment of the seat-adjustment assembly 500 between the extended position and the reclined position.
  • the motor activator block 340 moves rearward with respect to the rocker mechanism 410 while the motor mechanism 320 remains generally fixed in space, thereby adjusting the seat-adjustment assembly 500 from the extended position to the reclined position.

Further, these instructions may cause the linear actuator to carry out a complete first phase and/or second phase of movement. Or, the instructions may cause the linear actuator to partially complete the first phase or the second phase of movement. As such, the linear actuator may be capable of being moved to and maintained at various positions within a stroke of the first phase or the second phase, in an independent manner.
  • the combination of the motor mechanism 320, the track 330, and the motor activator block 340 may be embodied as a telescoping apparatus that extends and retracts in a sequenced manner.
