20080196204 | AUTO-RETURN PIVOT SYSTEM FOR DISPLAY APPARATUS - An auto-return pivot system for a display apparatus is provided. The auto-return pivot system comprises a base fixed to an article; a pivot fixed to the base; a support pivotally mounted around the pivot for supporting the display apparatus; a cam device connected with the support to determine a stop angle and an auto-return angle between the article and the support; and a pressure-storing device connected with the cam device for storing a pressure to be applied to the cam device in the axial direction of the pivot; wherein the pressure from the pressure-storing device enables the cam device to drive the support to automatically return to a position with the stop angle when an angle between the article and the support is smaller than the auto-return angle. | 08-21-2008 |
20090300883 | Hinge for a mobile video system - A hinge for use in conjunction with an overhead mobile video system includes a pivot rod fixedly coupled to a mounting bracket, a housing pivotally mounted upon the pivot rod and a friction spring interposed between the pivot rod and the housing controlling rotation of the mounting bracket relative to the housing. | 12-10-2009 |
20100101053 | HINGE ASSEMBLY - A hinge assembly includes a rotatable shaft, a rotatable stand, a fixed stand, a cam and a cam follower. The rotatable stand and the cam follower are non-rotatably connected to the rotatable shaft. The fixed stand and the cam are rotatably connected to the rotatable shaft. The cam is fixed to the fixed stand and contacted with the cam follower. The cam forms a limiting step, the cam follower forms a limiting surface on a periphery to abut against the limiting step. One of the cam and cam follower forms a positioning protrusion, the other one of the cam and cam follower defines a positioning groove to engage with the positioning protrusion. | 04-29-2010 |
20100154171 | Design and Implementation of Friction Hinge with a Range of Motion and Detent Separation Greater than 180 Degrees - A mobile phone or other electronic device is provided with an improved friction hinge with a radial range of motion greater than 180 degrees and with detents at both ends of travel. The friction hinge can include an asymmetrical cam in conjunction with a single tab on a follower. Advantageously, the electronic device with the improved friction hinge can allows a full 360 degree range of motion with any number of detents at any radial position. | 06-24-2010 |
20110265288 | TWO-STAGE DUAL-PINTLE HINGE - A two-stage dual-pintle hinge mainly includes at least one connecting element which has two apertures run through by a first axis and a second axis in the same direction. The first axis and the connecting element form a first pivot displacement, and the second axis and the connecting element form a second pivot displacement. The first and second axes have respectively a first anchor portion and a second anchor portion. The connecting element has a corresponding third anchor portion. During the first pivot displacement, the first anchor portion and the third anchor portion form an anchor relationship and drive the second pivot displacement of the connecting element and the second axis. During the second pivot displacement, the second anchor portion and the third anchor portion form an anchor relationship to stop pivoting. | 11-03-2011 |
20130081229 | HINGE DEVICE - A hinge device includes a shaft, a rotary cam, a fixed cam, and an elastic part that causes a side surface of the rotary cam to contact a side surface of the fixed cam. The side surface of the rotary cam includes a rotation-side reference surface, a rotation-side lower surface part, a rotation-side higher surface part, and an engaging recess. The side surface of the fixed cam includes a fixed-side reference surface, a fixed-side higher surface part, a fixed-side lower surface part, and an engaging protrusion. When the rotation-side lower surface part engages the fixed-side higher surface part, the engaging recess engages the engaging protrusion. When the rotation-side lower surface part is disengaged from the fixed-side higher surface part, the fixed-side higher surface part is in sliding contact with the rotation-side reference surface and the engaging protrusion is in sliding contact with the rotation-side higher surface part. | 04-04-2013 |
20130125343 | PNEUAMTIC PIVOTING FIXTURE WITH FRICTION ELEMENT - In a pivot fixture for pivotable parts, comprising a guide unit with a guide tube and an arrest unit with an engagement rod slidably disposed in the guide tube, the engagement rod is provided with control cam structures and an expansion body with a friction surface is slidably disposed on the engagement rod, the friction surface being arranged adjacent an inner wall section of the guide tube for engagement with the wall section upon expansion of the expansion body by the engagement rod. | 05-23-2013 |
20130160243 | HINGE MECHANISM - A hinge mechanism includes a fixed cam with first and second sector shaped protruding portions at a fixed cam surface and a rotating cam with first and second sector shaped concave portions at a rotating cam surface, wherein the first and second sector shaped protruding portions engage the first and second sector shaped concave portions and inner and outer periphery protruding portions at the first and second sector shaped protruding portions of the fixed cam surface engage inner and outer periphery concave portions at the first and second sector shaped concave portions of the rotating cam surface at an engaging position. Further, rotation side protruding portions formed at positions other than the concave portions of the rotating cam surface engages at least two positions of the protruding portions formed at the fixed cam surface, respectively, at a position other than the engaging position. | 06-27-2013 |
20140047672 | HINGE DEVICE - Provided is a hinge device which, both before and after the change of friction torque, maintains the friction torque, and is prevented from axial lengthening. A shaft member is rotatably supported by a stationary-side bracket, a cam member is axially movable, with its rotation being restricted by the shaft member, a biasing element applies a bias in the direction toward the place where the cam member and the bracket contact each other to generate friction torque, and a convex portion and a concave portion are formed on the cam member and the bracket, respectively, to be fitted to each other. Either the convex portion and/or the concave portion is/are shaped such that the torque changes according to the rotation angle of the shaft member, and the biasing element has the inflection point of a spring constant between the maximum and minimum values of the torque. | 02-20-2014 |
20150292252 | Hinge Assemblies - A hinge assembly is provided comprising a toggle type hinge ( | 10-15-2015 |
