Definitions

  • the present invention relates, generally, to the field of furniture and, more particularly, to the field of rocking chairs.
  • rocking chairs have a seat, a back, a pair of arms, legs, and a pair of opposed runners.
  • the legs typically connect between the seat and the runners, with each runner having an arcuate shape extending longitudinally forward and backward in partial contact with a surface on which the runners and rocking chair rest.
  • Such rocking chairs move a user sitting in the rocking chair in a gentle forward and backward rocking motion in response to the user alternately applying and removing a force on the chair's back that causes portions of the chair's runners to successively engage and disengage the surface beneath the runners.
  • the gentle forward and backward rocking motion provides the user with a soothing, relaxing sensation and may cause the user (or, for example, an infant held by the user) to become so relaxed that he/she falls asleep.
  • the present invention comprises a reconfigurable rocking chair that has multiple configurations, multiple rocking motions, and that is reconfigurable between multiple configurations and rocking motions in response to user input.
  • the reconfigurable rocking chair comprises an upper portion, a lower portion, and a lockable/releasable swivel assembly mounted between the upper and lower portions such that the rocking chair's upper portion is rotatable relative to the rocking chair's lower portion about a generally vertical axis between a first configuration and a second configuration.
  • the upper and lower portions are configured relative to one another such that a perpendicular extending from the seat side of the chair's back extends in a direction generally parallel to the longitudinal direction of the chair's runners and the chair's rocking motion moves a user forward and backward in a traditional, first rocking motion.
  • the rocking chair's leg ends are positioned in first positions relative to the end-to-end midpoint of the chair's runners with the first leg ends farthest from such midpoint and the second leg ends nearest such midpoint, thereby orienting the chair's center of gravity farther away from the midpoint of the chair's runners and nearer the runner's first ends and more easily enabling the rocking chair to move the user forward and backward.
  • the upper and lower portions are configured such that a perpendicular extending from the seat side of the chair's back extends in a direction generally perpendicular to the longitudinal direction of the chair's runners and the chair's rocking motion moves a user side-to-side in a non-traditional, second rocking motion.
  • the rocking chair's leg ends are positioned in second positions relative to the end-to-end midpoint of the chair's runners with the first and second leg ends substantially equidistant from such midpoint, thereby orienting the chair's center of gravity in general alignment with the midpoint of the chair's runners and more easily enabling the rocking chair to move the user side-to-side.
  • the rocking chair's lockable/releasable swivel assembly comprises upper and lower mounting plates defining respective races that receive a plurality of bearings therein, thereby enabling and permitting relative rotation between the upper and lower mounting plates (and, hence, relation rotation between the chair's upper and lower portions) while supporting and transferring loads.
  • the rocking chair's lockable/releasable swivel assembly further comprises a latch subassembly for locking the chair's upper and lower portions relative to one another when in the first or second configurations and for releasing the chair's upper and lower portions from one another so as to permit reconfiguration of the rocking chair (and repositioning of the chair's upper and lower portions relative to one another) between the first and second configurations.
  • the rocking chair's lower portion comprises multiple lockable/releasable leg end repositioning assemblies for, respectively, locking the leg ends of each chair leg in first and second positions relative to the runners when the rocking chair is, respectively, in the first and second configurations and for releasing the leg ends to permit repositioning of the leg ends between their first and second positions (and, hence, reconfiguring of the rocking chair between the chair's first and second configurations).
  • the lockable/releasable leg end repositioning assemblies each comprise multiple guides, multiple roller subassemblies, and an actuator mechanism that are operative in response to user input to lock, release and reposition the rocking chair's leg ends relative to the chair's runners.
  • the reconfigurable rocking chair is operable to move a user in a traditional, forward and backward, first rocking motion or in a non-traditional, side-to-side, second rocking motion.
  • the rocking chair's lockable/releasable swivel assembly and lockable/releasable leg end repositioning assemblies enable easy and rapid reconfiguration of the rocking chair in response to user input between first and second configurations corresponding, respectively, to such first and second rocking motions, thereby allowing a user to select and change between desired rocking motions.

  • Repositioning of the chair's legs 152 into their respective second positions is initiated when the caps 286 secured to the lever arms 272 of the actuator mechanisms 260 of the leg end repositioning mechanisms 180 attached to the first descending segments 174 of the legs 152 concurrently receive the exertion of respective forces tending to push the caps 286 away from the chair's seat 114 and overcoming the respective forces applied to the lever arms 272 by the biasing members 284.
  • the retractable pins 288 retract from holes 194 of guides 182 and allow rolling of the rollers 244, 304 of the roller assemblies 240, 300 atop the upper surfaces 158 of the runners 150 and within guides 182, 184 (and, hence, movement of the chair's legs 152 relative to the runners 150) between their first position in the first configuration and their second position in the second configuration.

  • the forces exerted by biasing members 284 on the lever arms 270 cause pivoting of the lever arms 270 and retractable pins 288 to become inserted into and present within holes 196 of guides 182, thereby then preventing movement of the chair's legs 152 relative to the runners 150 and securing the chair's legs 152 in their second positions relative to the runners 150.
  • the chair's center of gravity is located generally midway between the first and second ends 154, 156 of the chair's runners 150, thereby enabling and enhancing rocking in a non-traditional, side-to-side, second rocking motion.
  • the chair's upper portion 102 rotates relative to the chair's lower portion 104 into the second position of the chair's second configuration.
  • removal of force from the user interface cap 430 allows biasing member 434 to exert a force on the latch pin 424 causing insertion of the latch pin 424 into hole 406, thereby then preventing rotation of the chair's upper portion 102 relative to the chair's lower portion 104 and securing the chair's upper and lower portions 102, 104 in their second position.
  • the rocking chair 100 reconfigures into the first configuration in response to a user initiating repositioning of the chair's legs 152 into their respective first positions relative to the chair's runners 150 and initiating repositioning of the chair's upper portion 102 and seat 114 into the first position relative to the chair's lower portion 104.
  • Repositioning of the chair's legs 152 and repositioning of the chair's upper portion 102 and seat 114 into their first positions occurs, essentially, when the steps described above for reconfiguring of the chair's legs 152 and upper portion 102 in their first positions are reversed.
