|20090307871||HINGE STRUCTURE HAVING A KNUCKLE WITH ANTI-UNFOLDING PROPERTY - A hinge structure includes a shaft extending into a knuckle. The knuckle, when stretched-out, includes a knuckle body having a right portion and a left portion for coupling with the right portion. The knuckle body has a protrusion member projecting outwardly from the right portion with a neck section proximate to the right portion and a head section. The head section has a width greater than a width of the neck section. The knuckle body further has a recess member extending inwardly from the left portion with a narrow section proximate to the left portion and a large section. The large section has a width greater than a width of the narrow section. The width of the head section is greater than the width of the narrow section while the width of the neck section is smaller than the width of the narrow section in order to extend therethrough.||12-17-2009|
|20090293230||HINGE STRUCTURE WITH A FLEXIBLE LOCKING ASSEMBLY - A hinge structure is provided to include a knuckle, a pivot shaft and a flexible locking assembly. The pivot shaft extends rotatably into the knuckle, and has a peripheral locking section and a peripheral working section having a straight line. A flexible locking assembly is disposed within the knuckle, and includes a flexible element and a roller unit. The flexible element has a seating portion and one flexible leg extending from the seating portion in such a manner to contact the knuckle. The roller unit is disposed between the seating portion and the pivot shaft.||12-03-2009|
|20090077768||STRUCTURE AND MANUFACTURING METHOD OF COMBINATION-TYPE MALE HINGE - A method is applied to manufacture a combination-type male hinge comprising a connection portion and a shaft portion extended from the connection portion, and comprises the steps of: forming a plurality of connection plates by punching along at least one punching direction; making each connection plate have a punched peripheral surface and at least one perforating hole; making the punched peripheral surface have at least one sheared region and at least one torn region; and perforating the perforating holes of the connection plates by a extension bar extended from the connection portion, so as to connect the connection plates and manufacture the shaft portion of the combination-type male hinge.||03-26-2009|
|20080295288||HINGE STRUCTURE WITH AUXILIARY ROLLER UNIT - A hinge structure includes a knuckle having inner and outer surfaces, the inner surface being punched to protrude outwardly thereby forming a working surface defining a working region and a locking surface defining a locking region in spatial communication with the working region. The knuckle further has a slot axially extending through the inner and outer surfaces at the working region to provide resiliency thereof. A pivot shaft extends into the working region, and has a locking section and a working section. A roller unit is disposed within the locking region in such a manner to contact the shaft. When the locking section is aligned with the roller unit, the shaft is locked to the knuckle due to biasing action of the locking surface. When the working section is aligned with the roller unit, the shaft possesses a torque due to biasing action of the knuckle.||12-04-2008|
