Abstract: A folding swing chair frame includes two upright tubes connected mutually by a linkage group. The linkage group includes swing rods and at least two crossing tubes, and the crossing tubes are hinged with each other by a crossing point. Upper ends of the crossing tubes are respectively hinged to lower ends of the swing rods, and upper ends of the swing rods are respectively hinged to the upright tubes. The upright tubes are hinged to lower ends of the crossing tubes. Slide sleeve locking pieces are respectively disposed on at least one of the upright tubes and slide along a length direction of the upright tubes. A groove is disposed respectively on the slide sleeve locking pieces. When the frame is unfolded, the slide sleeve locking pieces fall down and the swing rods are sleeved in the grooves to perform locking between the upright tubes and the swing rods.

Abstract: A human support structure has: at least one support against which at least one part of a human body is borne; a base; a first motion transmitting assembly having first and second link members joined to each other and two components for pivoting movement around separate axes and defining a first unit; and a second motion transmitting assembly having third and fourth link members and two components joined together for pivoting movement around separate axes and defining a second unit. The first and second motion transmitting assemblies guide relative movement between the at least one support and the base. The first and second units can be selectively repositioned to change how relative movement between the at least one support and base is guided.

Abstract: The dual infant rocking device is adapted for use with two infant/toddlers. The infant/toddlers sit in the dual infant rocking device. The dual infant rocking device is a rocking structure. By rocking structure is meant that the one or more selected individuals seated in the dual infant rocking device are moved in a rhythmic motion relative to the force of gravity. The dual infant rocking device includes a pedestal structure, a plurality of seats, and a control circuit. The pedestal structure, the plurality of seats, and the control circuit are attached to form a single object. The plurality of seats receive the one or more selected individuals. The control circuit provides the motive forces that rock the plurality of seats. The pedestal structure transfers the loads of the plurality of seats, the one or more selected individuals, and the control circuit to a supporting surface.

Abstract: A swingable chair chassis comprises a rocker seat including a chamber defined between a bottom wall and a peripheral wall. The bottom wall includes a slot extending in a front/rear direction. A lid is securely mounted to a bottom of the seat and the rocker seat. A supporting seat is disposed in the chamber of the rocker seat. The supporting seat includes a central portion having an insertion hole coupled with chair post. The supporting seat includes an arcuate supporting face formed on an upper side thereof and abutting against a lower face of the lid. A plurality of elastic elements is disposed between the bottom wall of the rocker seat and the supporting seat and provides movement elasticity when the rocker seat swings forward or rearward relative to the supporting seat. The supporting face abuts against the lower face of the lid during swinging movement of the rocker seat.

Abstract: A reciprocating seating unit includes: a base; a frame including a generally horizontal seat and opposed arms; a backrest; a reciprocating unit attached to the base, the reciprocating unit configured to permit reciprocating longitudinal movement of the frame and backrest relative to the base; and a reclining mechanism attached to the reciprocating unit, the frame and the backrest. The reclining mechanism includes pivotally interconnected links and is configured to move the backrest between an upright position, wherein the backrest takes a first backrest angle relative to the underlying surface and the frame is positioned relative to the base in a first location, and a reclining position, wherein the backrest takes a second backrest angle that is shallower than the first backrest angle, and the frame is positioned relative to the base in a second location that is at least 3 inches in front of the first location.
