  • Patent number: 7100975
    Abstract: Methods and apparatus are provided in which a collapsible rocking chair has legs that translate towards and away from each other to configure the chair between open and collapsed dispositions, and at least one leg that slidably articulates with a rocker. Preferred embodiments have four legs. The left back leg slidably articulates with a left rocker, and the right back leg slidably articulates with a right rocker. The front legs are pivotally coupled to the respective rockers at fixed points. The back frame is preferably coupled to the left and right legs at pivots, allowing the back to approximate the seat during folding. Both back and seat are preferably formed from a fabric material, and more preferably from a single continuous piece of fabric. Preferred rocking chairs also include left and right armrests, supported at least in part by the back frame.

  • Patent number: 5975626
    Abstract: A cross-member supporter for foldable furniture enables at least two construction members to selectively be supported in strongly extended cross structure or be folded in parallel compact structure for easy storage and carrying purposes. The cross-member supporter includes a supporter body having at least two vertical connecting holes and two inclined supporting holes provided therethrough. The two inclined supporting holes are inclined in opposite direction. The two inclined supporting holes are respectively extended from top to bottom through the two vertical connecting holes to form two supporting through slots. An axis of the vertical connecting hole of each of the supporting through slots is intersected with an axis of the respective inclined supporting hole, wherein each of the supporting through slots defines an upper supporting groove and a lower supporting groove which are inclined in opposite direction.
