Patent number: 7490895Abstract: A collapsible high chair frame including a supporting stand, a seat, a connecting device and a positioning device. The supporting stand is provided with a rear and a front supporting leg which are foldable toward each other. The seat has a base and a back which are connected pivotally to each other. The connecting device is pivotally coupling to the supporting stand and the seat. According to the configuration of this invention, the connecting device is rotatable by releasing a lock on the positioning device which is arranged between the connecting device and the seat, meanwhile, the rear supporting leg is closed up to the front supporting leg and also folded toward the base and back of the seat at the same time. The collapsible high chair can be stored with a compact frame.Type: GrantFiled: December 12, 2005Date of Patent: February 17, 2009Assignee: Link Treasure LimitedInventor: Chuan-Ming Yeh

Patent number: 6851745Abstract: The infant product of the invention is of the type having an infant receptacle suspended from a frame. The infant product is foldable between a deployed position for use and a compact configuration for shipping and storage. In the assembled configuration, the infant receptacle is convertible between a bassinet configuration in which the infant receptacle has a substantially planar support surface and an infant seat configuration in which the support surface of the infant receptacle is partially titled or disposed at an angle such that the infant can be supported in an elevated or seated position. The infant product may include a fabric canopy incorporating floating webs and a quick connect system for securing the canopy in an open position. When the canopy is closed, it is folded so as to lie flat against the infant receptacle. The infant receptacle may also include a lateral support assembly to cradle the infant.Type: GrantFiled: April 12, 2002Date of Patent: February 8, 2005Assignee: Fisher-Price, Inc.Inventors: Julia Favorita nee Wilkins, John S.

Patent number: 6213923Abstract: An exercise device and methods for strengthening the muscles of lower back and abdomen. The device may be configured to impart extension to the spine of a user. The device may include a reclinable chair having a backrest pivotally attached to a seat. The backrest may be pivotally declined backwards in relation to the seat by a user during exercise. The device may include a decline control mechanism that is selectively operable to resist the decline of the backrest, to limit the maximum angle of decline of the backrest relative to the seat, or both.Type: GrantFiled: March 30, 1999Date of Patent: April 10, 2001Assignee: Cape Hatteras Management LimitedInventors: William J.

Patent number: 5782528Abstract: A folding chair (1) which consists of a seat (5) foldable; two pairs of struts, front (2) and rear (3) which converge on and connect to the chair back (6) functioning as legs and being connected to each other respectively by a rear horizontal cross-bar (9) and a front horizontal cross-bar (8). The rear struts (3) are formed by two tubes (31, 32) slidable one inside the other, the internal tube (32) being fixed by at least one connector (7) to the top of the front strut (2) in correspondence with the chair back, the external tube (31) being fixed to its twin by said rear cross-bar (9). The partial extraction of the internal tube (32) from the external tube (31) occurring when the chair is lifted by the back (6) allows the rotation of the seat around the axis of said rear cross-bar (9).Type: GrantFiled: June 12, 1997Date of Patent: July 21, 1998Inventor: Enrico Cioncada

Patent number: 5328232Abstract: Disclosed is a foldable, injection molded plastic chair in which the seat of the chair is engageable in a generally horizontal seating position with application of little force, with the seat engagement members preventing the seat from moving out of its horizontal seating position until application of significantly greater force thereto, thereby providing a chair having improved load withstanding capability. The seat is mounted for pivotal engagement to the legs of the chair by an improved keyed post interlock arrangement which can withstand heavy loading and still retain the pivotal engagement of the seat with the chair legs.Type: GrantFiled: June 17, 1992Date of Patent: July 12, 1994Assignee: Suncast CorporationInventor: Steven P. Whitehead

Patent number: 5154472Abstract: A chair having a seating unit and two pairs of legs made slidably integral by couplings attached to the seating unit and designed to engage the relevant inserts located in such first pair of legs, which are made to slide in relation to the second pair of legs by further couplings located in further inserts provided on the second pair of legs, so as the couplings are designed to allow substantially continuous tilt adjustment of the seat and of the backrest relative to the seat, as a result of the relevant pushing action exerted by the user while assuming various positions that are balanced by the push up action.Type: GrantFiled: June 13, 1991Date of Patent: October 13, 1992Inventor: Yaacov Kaufman

Patent number: 4826196Abstract: A portable wheelchair having a metal wire frame is provided. The individual frame members are interconnected by clinched loop, hinged connections, and fold together in a manner that minimizes the space required for the stored configuration of the wheelchair. The metal wire fabrication also minimizes the wheelchair weight and the visual profile of the wheelchair in its deployed configuration.Type: GrantFiled: November 2, 1987Date of Patent: May 2, 1989Assignee: Sitgo CorporationInventors: George R. D. Kirkpatrick, John R. Trescott
