Definitions

  • the present invention relates generally to a furniture and more particularly, to a base seat adapted for being used with a bed, a chair or a sofa and provided with a function of swinging in any direction, i.e. universal direction.
  • JPS6253613A discloses a chair, comprising a bottom of the seat to be positioned above a hanging part, formed in a holding frame, and a support rising part of the support frame to which the seat is connected in the upper part is arranged in a front-back direction.
  • the structure is such that the suspension frame extends from above the upper two halves toward the four hanging portions formed in the lower corner, and the holding frame has a holding rising portion from the lower halves in the left-right direction.
  • the supporting frame is suspended from the holding frame by the four suspenders, so that the structure is directed to the four hanging portions formed in the upper corner.
  • US2007129156 A1 discloses a child motion device with a frame assembly configured to rest on a floor surface.
  • the device also has a drive system that drives a swing assembly.
  • the swing assembly can include a pair of swing arms having proximal ends and distal ends. The distal ends support a child seat assembly. The distance between the distal ends relative to the distance between proximal ends is adjustable, thereby adjusting at least one motion characteristic of the device.
  • the adjustable motion characteristics can include a gliding motion and a swinging motion.
  • US5263677 discloses a suspension framework for a chair or piece of sleeping furniture, which is able to oscillate, is comprised of a support member, which is connected to the sitting or sleeping surface and arranged on both sides thereof, and which is connected with a base support member, via rope-type pendulums.
  • At least two rope-type pendulums engage the support member on each side thereof. This will enable, in a system having satisfactory stability characteristics, a high degree of sensitivity in response to very minute movements of the human body or under oscillating conditions occurring in the human body that is seemingly at rest.
  • the present invention has been accomplished in view of the above-noted circumstances. It is an objective of the present invention to provide a base seat for being used with a bed, chair or sofa, which can swing in any direction, i.e. universal direction, or at least multi-directions, thereby preventing users from feeling bored and/or fatigue due to a monotone swinging motion.
  • Another objective of the present invention is to provide a base seat for being used with a bed, chair or sofa, which has proper variable inclined angles during swinging, such that users may feel easy and comfortable to fully relax.
  • the present invention provides a base seat, which is adapted for being used with a bed, a chair or a sofa, comprising a fixation base, a first rocking mount, a first drive device, a second rocking mount, and a second drive device.
  • the fixation base includes a front frame body and a rear frame body.
  • the first rocking mount is connected with the front frame body of the fixation base via two front suspension arms in a way that each of the two front suspension arms has a top end pivotally connected with the front frame body and a bottom end pivotally connected with the first rocking mount, and a first distance between the top ends of the two front suspension arms is smaller than a second distance between the bottom ends of the two front suspension arms.
  • the first rocking mount is also connected with the rear frame body of the fixation base via two rear suspension arms in a way that each of the two rear suspension arms has a top end pivotally connected with the rear frame body and a bottom end pivotally connected with the first rocking mount, and a first distance between the top ends of the two rear suspension arms is smaller than a second distance between the bottom ends of the two rear suspension arms.
  • the first rocking mount is swingable leftward and rightward relative to the fixation base along a first arc path with a variable inclined angle thereof.
  • the first rocking mount comprises a right frame body and a left frame body.
  • the first drive device is disposed between the fixation base and the first rocking mount to drive the first rocking mount to reciprocatingly swing leftward and rightward relative to the fixation base.
  • the second rocking mount is connected with the left frame body of the first rocking mount via two left suspension arms in a way that each of the two left suspension arms has a top end pivotally connected with the left frame body and a bottom end pivotally connected with the second rocking mount, and a third distance between the top ends of the two left suspension arms is smaller than a forth distance between the bottom ends of the two left suspension arms.
  • the second rocking mount is also connected with the right frame body of the first rocking mount via two right suspension arms in a way that each of the two right suspension arms has a top end pivotally connected with the right frame body and a bottom end pivotally connected with the second rocking mount, and a third distance between the top ends of the two right suspension arms is smaller than a forth distance between the bottom ends of the two right suspension arms.
  • the second rocking mount is swingable forward and backward relative to the first rocking mount along a second arc path with a variable inclined angle thereof.
  • the second rocking mount is configured to support the bed, the chair or the sofa thereon.
  • the second drive device is disposed between the first rocking mount and the second rocking mount to drive the second rocking mount to reciprocatingly swing forward and backward relative to the first rocking mount.
  • the base seat may have a function of swinging in any direction, i.e. universal direction, so as to prevent users from feeling bored and/or fatigue due to a monotone swinging motion, and provide a proper variation of the inclined angle during swinging, such that users may feel easy and comfortable so as to fully relax.
