Abstract
A hinge device for pivotally coupling a display (70) to a base (80) of an electronic device. The hinge device includes a seat (30) securing in the base and a rotor (40) attached to the display. The seat defines a center through hole (35) therein and a railway (36) in an inner wall of the seat. The rotor includes a shaft (42) pivotally received in the center through hole of the seat and a pair of opposite beams (43) connecting to the display. At least one socket (45) is defined in an outer wall of the shaft. A roller (50) is tightly held between the socket of the rotor and the railway of the seat. The roller moves along the railway when the rotor rotates in the seat. The display swivels relative to the base and alters the vertical distance from the base.
Claims21
A hinge device for pivotally coupling a display to a base of an electronic device, the hinge device comprising:
- a seat adapted to be secured with the base, the seat defining a hole therein, a railway defined in an inner wall of the seat;
- a rotor adapted to be secured with the display, the rotor comprising a shaft pivotally received in the hole of the seat and a beam fixed with the display;
- and
- at least one roller located on the rotor and movably received in the railway of the seat;
- wherein when the shaft of the rotor rotates in the hole of the seat, the at least one roller moves along the railway to cause the rotor to move in an axial direction of the shaft.
A hinge device assembly comprising:
- a base;
- and
- a hinge device for coupling a display to a base, the hinge device comprising:
- a pair of first hinges each comprising a first rotating member and a second rotating member pivotally engaging with the first rotating member, the second rotating member being secured in the display;
- and
- a second hinge comprising a seat engaged with the base and a rotor engaged with the first member, the seat pivotally engaged with the rotor;
- wherein when the display rotates relative to the base in a direction parallel to the base, the rotor is moved in a direction perpendicular to the base thereby driving the display to move in said direction perpendicular to the base.
A hinge device assembly comprising:
- a seat secured with a first part, the seat defining a first engagement device defining an vertical axis and a first guiding device thereof;
- a rotor secured with a second part, the rotor comprising a second engagement device defining along said vertical axis and engaged with said first engagement device along said vertical axis, and thereof a second guiding device guidably engaged with the first guiding device;
- wherein
- the rotor is rotatable relative to the seat about said vertical axis under a condition that during rotation said rotor is forced to move up and down along said vertical axis due to engagement between said first and second guiding device so as not to have third and fourth part interfere with each other wherein said third part is attached to the first part and said fourth part is attached to the second part.
