Rotary type hinge device for portable wireless terminal
First Claim
1. A rotary type hinge device for a portable wireless terminal, which is installed between a terminal body and a folder of the portable wireless terminal, the hinge device comprising:
- a first rotation axis for opening and closing the folder with respect to the terminal body and a second rotation axis extending perpendicular to the first rotation axis and adapted to rotate relative to the first rotation axis, the hinge device being adapted to rotate the folder about the second rotation axis in a state wherein the folder and terminal body are opened;
a first hinge housing coupled to the terminal body to rotate about the first rotation axis, the first hinge housing being formed with a fixing portion at its inner peripheral surface, and an opening adapted to expose the fixing portion in a direction of the second rotation axis;
a main shaft provided at one end with a fixing end having a shape corresponding to that of the fixing portion, the main shaft extending in the direction of the second rotation axis and being adapted to protrude outwardly through the opening of the first hinge housing at the other end thereof; and
a second hinge housing rotatably coupled to the other end of the main shaft protruding outwardly from the first hinge housing and adapted to rotate about the second rotation axis, the second hinge housing being fixed to the folder,wherein a flexible printed circuit protrudes from an interior space of the folder and extends longitudinally at one side of the main shaft, thereby entering into the first hinge housing through the opening thereof, and the flexible printed circuit is wound at least half way around the main shaft within the first hinge housing and then drawn from one side end of the first hinge housing.

Abstract
A rotary type hinge device, installed between a terminal body and a folder of the portable wireless terminal. The hinge device has a first rotation axis for opening and closing operations of the terminal body and folder, and a second rotation axis extending perpendicular to the first rotation axis to be rotated relative to the first rotation axis. The hinge device is adapted to rotate the folder about the second rotation axis in a state wherein the folder and terminal body are opened. The hinge device comprises a first hinge housing coupled to the terminal body to rotate about the first rotation axis; a main shaft having its one end fixed to the inner peripheral surface of the first hinge housing and the other end thereof protruding outwardly from one side of the first hinge housing; and a second hinge housing rotatably coupled to the other end of the main shaft protruded outwardly from the first hinge housing and adapted to rotate about the second rotation axis. The second hinge housing is fixed to the folder. The rotary type hinge device constructed as stated above enables the biaxial rotation of the folder, thereby allowing the reversal of front and rear surfaces thereof. Therefore, the portable wireless terminal has advantages that the change of the specification or design thereof is easy and its convenience of use is increased.

14. A rotary type hinge device for a portable wireless terminal comprising:
-
a first hinge housing, which is rotatable about a first rotation axis longitudinally extending through both cads thereof, the first hinge housing being formed at its inner peripheral surface with a fixing surface, and at its outer peripheral surface with an opening adapted to expose the fixing surface perpendicular to the first rotation axis; a main shaft provided at one end with a fixing end having a shape corresponding to that of the fixing surface, the main shaft extending from the fixing end in a direction perpendicular to the first rotation axis, and being adapted to protrude outwardly through the opening of the first hinge housing at the other end thereof, thereby providing a second rotation axis; a second hinge housing rotatably coupled to the other end of the main shaft and adapted to rotate about the second rotation axis; a perforated hole formed at a lower end surface of the second hinge housing; a shaft cam provided at the other end of the main shaft and adapted to be inserted through the perforated hole, thereby being positioned within the second hinge housing, the shaft cam being formed at its outer peripheral surface with at least one pair of stopper recesses arranged on opposite sides of the shaft cam, respectively; and stopper cams formed at their respective one ends with stopper projections having a shape corresponding to the stopper recesses, respectively, the stopper cams being adapted to stop a rotation of the second hinge housing by receiving an elastic force within the second hinge housing at a position that the stopper recesses and stopper projections come into close contact with each other, respectively, the stopper cams linearly reciprocating within the second hinge housing in accordance with the rotation of the second hinge housing. - View Dependent Claims (15, 16, 17, 18)
