  • Patent number: 10524575
    Abstract: A rocking furniture member may include a base frame, a seat assembly, a legrest mechanism, and a pawl assembly. The seat assembly may include a ratchet rack having a plurality of teeth. The pawl assembly may include a support link, a pawl arm, and an actuation link. The support link is rotatably coupled to the base frame. The pawl arm is rotatably attached to the support link and selectively engages one of the ratchet teeth. The actuation link may be attached to the pawl arm and may be coupled to the legrest mechanism such that movement of the legrest mechanism into the extended position moves the pawl arm into engagement with the ratchet rack and movement of the legrest mechanism toward the retracted position causes rotation of the pawl arm relative to the support link and disengages the pawl arm from the ratchet rack.

  • Patent number: 8801098
    Abstract: A motorized chair system for promoting movement, balance, and vestibular processing and integration. The chair system features a chair component comprising a back support portion disposed atop a seat portion. The back support portion is formed from a first side panel, a middle panel, and a second side panel connected together, wherein rigid intersections are formed between the side panels and middle panel. A rocking component is positioned below the chair component. The rocking component is shaped to allow the chair component to rock. A motor system is operatively connected to a piston, the piston being mounted to a ground surface. The motor system functions to automatically rock the chair component forwardly and backwardly by pushing against the piston to pivot the system in a forward motion. A control button is operatively connected to the motor system. The control button functions to turn the motor system on and off.

The rocker recliner can be reclined by rotating a recline lever on the side of the rocker recliner, and reclining the rocker recliner can also cause the extension of a footrest. A lockout lever, which is attached to the rocker recliner, is configured to be moved by a user between a locked position and an unlocked position.

    Abstract: The present invention relates to a locking assembly for a rocking chair. The locking assembly includes a pair of jaws mounted to the body-supporting portion of the chair and a set of pins mounted to the chair base portion of the chair. The jaws are operable to engage a selected pin to lock the body-supporting portion of the chair relative the chair base portion in a position that corresponds to the selected pin. The jaws include gripping faces that spread apart to define a recess when the locking assembly is operated. At the same time the gripping faces move toward the pin to cause the pin to enter the recess such that the pin becomes wedged in the recess.

  • Patent number: 6588527
    Abstract: A device for automatically rocking a stroller. Winding structure includes a connecting rod, whose first end is eccentrically mounted to the spring structure and whose second end is equally eccentrically mounted to the wheel axle extension so that the forward movement of the stroller winds the spring structure. The rocking structure includes a rod whose far end is mounted eccentrically to the wheel axle extension and whose forward end is less eccentrically mounted to the spring structure to ensure that the rod assumes a reciprocating motion during the unwinding of the spring structure. The user switches from winding mode to rocking mode. In an alternative embodiment a first rod attached to the shaft includes a lever that assumes different positions, the different lever positions changing the degree to which a second rod is eccentrically mounted to the spring structure and determining whether the device is in winding or rocking mode.

  • Patent number: 6406095
    Abstract: A self-locking system comprising a state selector for detecting the intent of an occupant to rise from a chair and then automatically causing a lock to block the mobility functions of the chair. The state detector is responsive to movement of an upper portion of the body of the occupant while the occupant is still supported in a normal seated position on the seat of the chair, thereby advantageously allowing the locking of the mobility functions of the chair to occur before the occupant starts to lift his weight from the seat of the chair.

  • Patent number: 6402243
    Abstract: A safety harness structure for a rocking chair. The structure includes a support frame and a chair mounting on the support frame through a pair of swinging bars. The swinging bars are pivotally engaged with two sides of the support frame and the chair through pivotal shafts located at the junctures of the support frame and the chair. The chair may swing to and fro relative to the frame about the pivotal shafts which function as fulcrums. The swinging bars are pivotally bridged by a restrictive rod for limiting the swinging angle of the swinging bars thereby to maintain the chair swinging within a selected displacement.

  • Patent number: 6244658
    Abstract: The rocking chair includes a ground-resting base, a seat support frame and rocking arms rockably mounting the seat support frame to the base. A seat, defining a front end portion and a rear end portion, is pivotally mounted on the support frame at its front end portion allowing limited up and down movement of its seat rear end portion between an upper position and a lower limit position. A stop is carried by said seat support frame and engages the seat rear end portion in its lower limit position. A spring continuously forces the seat towards said upper position, and the weight of a person seated on the seat rear end portion will effectively lower the seat rear end portion to its lower limit position against the bias of the spring. The rocking chair also includes a unidirectional two part ratchet locking device having a ratchet wheel carried by one of the rocking arms, and a pawl pivotally carried by the seat support frame.
