  • Patent number: 7818846
    Abstract: 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.

  • Publication number: 20090307871
    Abstract: 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.

  • Publication number: 20090293230
    Abstract: 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.

  • Patent number: 7600296
    Abstract: A hinge structure includes a pivot shaft, a knuckle receiving the pivot shaft rotatably therein, and a disc locking mechanism. The knuckle has a front-end face formed with a retention recess. The locking mechanism includes a positioning disc disposed adjacent to the front-end face of the knuckle to permit extension of the pivot shaft therethrough, and having an inner surface facing the front-end face and formed with a reception recess. The positioning disc is rotatable simultaneously with the pivot shaft. A roller is sandwiched between the front-end face and the positioning disc in such a manner to engage the retention recess and the reception recess when the retention recess is aligned with the reception recess, thereby preventing rotation of the pivot shaft in the knuckle.

  • Patent number: 7578031
    Abstract: 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.

  • Publication number: 20090083941
    Abstract: A hinge structure comprises a male hinge and a female hinge. The male hinge comprises a shaft extended along a first extension direction, and at least one hinge cap formed with at least one positioning structure. The female hinge comprises a female hinge connection portion and a socket portion. The socket portion is extended from the female hinge connection portion, hitches the shaft, forms with at least one hole to make the socket portion be flexible along the first extension direction, and comprises at least one positioning member neighboring to the hinge cap. The positioning member positions the male hinge when the shaft rotates to make the positioning structure match to the positioning member. The socket portion is stretched or compressed along the first extension direction when the shaft rotates to make the positioning structure apart from the positioning member.
