Publication number: 20150092335Abstract: A frictional hinge assembly for use with electronics devices such as computer notebooks having base and lid portions may present a higher level of frictional resistance to rotation in one direction than in the other. The hinge may comprise a base-mounted helical sleeve having loops that embrace a rotational shaft that is connected to a lid. As the lid is opened, the rotation of the shaft may cause the loops of the helical sleeve to tighten and thereby generate frictional forces, which requires a greater opening force to overcome than when the lid is being closed, in which case the loops loosen. The helical hinge may have applicability for notebook computers, electronic devices having clamshell form factors, all-in-one designs and tablets using kickstands and the like.Type: ApplicationFiled: September 27, 2013Publication date: April 2, 2015Inventors: JOHNSON S.

Patent number: 8272695Abstract: There is disclosed herein a hinge assembly comprising a mandrel having a longitudinal axis. A first arm is rotationally fixed relative to the mandrel and extends from one end of the mandrel generally transverse to the longitudinal axis. A second arm is rotatably connected relative to the mandrel about the longitudinal axis and extends from the opposite end of the mandrel generally transverse to the longitudinal axis. A coil spring is sleeved over and snugly surrounds the mandrel. Relative rotation of the first arm and the second arm in an opposite direction tightens the spring around the mandrel. Tightening of the spring generates resistance to relative rotation of the first arm and the second arm.Type: GrantFiled: October 14, 2010Date of Patent: September 25, 2012Assignee: King Furniture (Australia) Pty Ltd.Inventors: David Russell King, Steven Leonard Higgs

Patent number: 8250710Abstract: An interfering assembly of a hinge includes a male element including a first raised portion and a second raised portion, and a female element defining a through hole. A sliding surface apart from a center of the through hole protrudes from the female element. An inner slot and an outer slot are formed beside the sliding surface. The female element defines a first depressed portion and a second depressed portion correspondingly engaged with the first and second raised portions. Widths of the inner slot and the outer slot are gradually varied. During rotation of the rotating member, the first and second raised portions are slid out from the first and second depressed portions, respectively, and then in frictional engagement with the sliding surface, together with partial portions covering the inner and outer slots, correspondingly.Type: GrantFiled: May 31, 2010Date of Patent: August 28, 2012Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Jung-Bin Chang

Patent number: 8230554Abstract: A hinge has a pintle, a spacer assembly, a stationary bracket and a rotating bracket. The pintle is mounted through the spacer assembly and is connected to the stationary and rotating brackets. The spacer assembly has multiple spacers stacked with each other. Each spacer has a ring segment and a bearing segment. The ring segment is mounted around the pintle. The bearing segment has an absorbing space to absorb the stress acting on the ring segment. Therefore, the spacer sustains less stress to prevent breakage easily and a lifespan of the spacer is extended. Therefore, the hinge has a longer lifespan.Type: GrantFiled: March 26, 2010Date of Patent: July 31, 2012Assignee: Shin Zu Shing Co., Ltd.Inventors: Chin-Sheng Chu, Chung-Yu Lee, Lu-Yu Chiang
