Patent number: 7475900Abstract: A stroller frame including a wheeled support, a lower support joint, an upper support, and a connecting joint that commonly form a foldable linkage system. The wheeled support has a pair of push bars and an actuator associated with a flexible element, so as to control the rotation of each push bar. When the end of the push bar is released, the connecting joint is driven by the push bars and carries the wheeled support, the lower support joint, the upper support, which are simultaneously rotated and moved from an erect position to a collapsed position. The upper support is furnished with a connector for detachably securing a stroller seat, a safety seat, or an infant carrier. In addition, the lower support joint may extend upwardly with a plurality of extension arms for detachably securing two seats, two safety seats or an infant carrier. This provides a stroller frame having multiple uses and greater convenience.Type: GrantFiled: October 12, 2006Date of Patent: January 13, 2009Assignee: Link Treasure LimitedInventor: Huang-Yi Cheng

Publication number: 20070163041Abstract: A joint structure for a collapsible play yard suitable for infants or pets, which is pivotally connected between a pair of upper rails of a foldable fame. The pair of tipper rails can either be locked precisely in alignment or be released and folded in a parallel arrangement. Therefore, the foldable frame can either be fixed in a deployed state or converted into a collapsed state. When the foldable frame is fixed in the deployed state, the upper rails are locked by a pair of pins, whereby the pins are supported by a pair of slots of the housing of the joint structure. A release button is equipped on the outside of the housing of the joint structure for pushing by a user, so as release the pins from the upper rails, thereby permitting the upper rails to be unlocked, rotated and folded in a parallel arrangement.Type: ApplicationFiled: March 2, 2006Publication date: July 19, 2007Inventors: Huang-Yi Cheng, Chi-Yung Lin

Patent number: 7153181Abstract: A toy support structure includes, a plurality of pivots provided on a center housing such that each axle center of the pivots is parallel to the axle center of center housing. By rotatably connecting the pivots and the hanging support set, the hanging support set can rotate in relation to the pivots so as to extend in radial form. Further, the hanging support set can rotate in relation to the pivots so as to be arranged in parallel on the same plane, thereby reducing the volume and accomplishing the ease of carrying and storage.Type: GrantFiled: February 16, 2005Date of Patent: December 26, 2006Assignee: Link Treasure LimitedInventors: Huang-Yi Cheng, Chi-Yung Lin

Publication number: 20060192419Abstract: An adjustable back for high chair having a seat consists of a seat base pivotally connected to a seat back, and a plurality of positioners are disposed in an arc arrangement on both sides of the seat. The seat back is provided with an adjustable device which includes a handle. The handle can be manipulated by only one hand of the user to control the locking members indirectly via a linkage levers in order to engage or disengage the locking members from the positioners. This structure is easy for the user to adjust the seat inclination by only one hand and also reduces the cost with its simple components to be easily assembled.Type: ApplicationFiled: February 17, 2006Publication date: August 31, 2006Inventors: Huang-Yi Cheng, Yung-Shuen Lin, Chi-Yung Lin
