Patent number: 7640628Abstract: A hinge assembly (300) for use in a flat display monitor includes a base seat (10), a fixing seat (20), a pivotal shaft (30), a resilient element (80) and a plurality of washers. The base seat includes a pivot flange (14) having a retaining hole (12) formed therein. The pivot flange defines a protrusion (18) therein, and the protrusion extending into the retaining hole. The fixing seat includes an extending portion (26) defining an engaging hole. The resilient element resists between the base seat and the fixing seat. The pivotal shaft has at least one flat surface, and the pivotal shaft is positioned within the retaining hole of the pivot flange. One of the at least one flat surface pivotably engages with the protrusion. The pivotal shaft extends beyond the retaining hole of the pivot flange, and the plurality of washers is fastened together to the pivotal shaft.Type: GrantFiled: August 4, 2006Date of Patent: January 5, 2010Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: An-Kui Hu

Patent number: 7353569Abstract: A hinge assembly (100) for use in a flat display monitor (120) includes a base seat (10), a pivotal shaft (20) and a plurality of washers (30, 40, 50, 60, 70). The base seat includes a first end portion (12) and a second portion (14), which are substantially perpendicular to each other. The first end portion has a retaining hole (122) therein. A protrusion (124) of the first end portion extends into the retaining hole. The pivotal shaft includes a pivotal portion (24). The pivotal portion has at least one flat surface (242) pivotally engaging with the protrusion. The pivotal shaft passes through the retaining hole of the base seat and the plurality of washers, allowing the elements of the hinge assembly to be fastened together.Type: GrantFiled: November 18, 2005Date of Patent: April 8, 2008Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Yong-Jian Chen, An-Kui Hu, Fan Zhou

Publication number: 20070136995Abstract: A hinge assembly (300) for use in a flat display monitor includes a base seat (10), a support seat (20) and a pivotal mechanism. The pivotal mechanism comprises a pivotal shaft (30) having at least one flat surface (310). The base seat defines a pivotal hole (142) therein. The support seat defines an engaging hole (242). The base seat is rotatable relative to the support seat. The pivotal shaft passes through the pivotal hole of the base seat and the engaging hole of the support seat. One of the base seat and the support seat defines a protrusion (143). The protrusion is substantially V-shaped and has two edges (1432, 1434). The flat surface of the pivotal shaft pivotally engages with the protrusion. Another one of the pivotal hole of the base seat and the engaging hole of the support seat non-rotatably engages with the pivotal shaft.Type: ApplicationFiled: August 16, 2006Publication date: June 21, 2007Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: An-Kui Hu, Yan-Qun Wen

Publication number: 20070136994Abstract: A hinge assembly (300) for use in a flat display monitor includes a support seat (10), a base seat (20) and a pivot mechanism. The support seat has a cutout (164) defined by two opposed side surfaces. The base seat includes a resisting member disposed thereon. The pivot mechanism rotatably connects the support seat to the base seat. A resisting member (94) on the base seat is movable in the cutout of the support seat upon rotating of the support seat relative to the base seat. The two side surfaces are configured to engage with the resisting member when the support seat rotates relative to the base seat in a manner so as to prevent the resisting member from moving further to limit a rotation angle between the support seat and the base seat.Type: ApplicationFiled: August 4, 2006Publication date: June 21, 2007Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: An-Kui Hu

Publication number: 20070119025Abstract: A hinge assembly (300) includes a support seat (10), a base seat (20) and a pivot mechanism (30). The support seat defines a pivoting hole (160). The base seat defines an engaging hole (242). The pivot mechanism rotatably connects the support seat to the base seat. The pivot mechanism includes an irregular-holed tab washer (41) defining an irregular hole (414) and a pivotal shaft (31). The pivotal shaft non-rotatably engages in the engaging hole of the base seat and rotatably engages in the pivoting hole of the support seat. The irregular-holed tab washer surrounds the pivotal shaft and is non-rotatably mounted to the support seat. The pivotal shaft engages with the irregular hole of the irregular-holed tab washer for limiting a rotation angle between the support seat and the base seat.Type: ApplicationFiled: August 16, 2006Publication date: May 31, 2007Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventor: An-Kui Hu
