Specifically, the first hinge shaft 311 is disposed on one side of the hinge housing so that the shaft portion 311a protrudes from one end surface of the hinge housing. Accordingly, the protruding shaft portion 311a is combined with the folder in a state of being coupled to the folder. Rotate together as the folder rotates. The first hinge cam 313 is disposed to face the first hinge shaft 311 coaxially. The first hinge cam 313 performs a linear movement in the hinge housing by a sliding cam movement in accordance with the rotation of the first hinge shaft 311. Of course, the linear movement is formed in the first guide protrusion 313a provided on the first hinge cam and the hinge housings 330 and 340, and the linear first guide moves in the state where the first guide protrusion 313a is inserted. This is due to the slits 332 and 342. The first hinge spring 312 is disposed between one end of the hinge housing and the first hinge shaft 311 to closely contact the first hinge shaft 311 to the first hinge cam 313. The close contact force provided by the first hinge spring 312 maximizes the sliding cam movement.

The configuration of the second hinge part 320 according to the present invention will be described in detail with reference to FIGS. 3 and 4. As shown in FIGS. 3 and 4, the second hinge part 320 may include a second hinge shaft 321, a first-first hinge spring 322, and a second hinge cam in the hinge housings 330 and 340. 323, the second-first hinge spring 324, and the second dummy shaft 325 are disposed to be sequentially received. Specifically, the second hinge shaft 321 is disposed on one side of the hinge housing so that the shaft portion 321a protrudes from one end surface of the hinge housing. Accordingly, the protruding shaft portion 321a is combined with the folder while being coupled to the folder. Rotate together as the folder rotates. The second hinge cam 323 is disposed to face the second hinge shaft 321 coaxially. The second hinge cam 323 performs a linear movement in the hinge housing by a sliding cam movement in accordance with the rotation of the second hinge shaft 321. Of course, the linear movement is formed in the second guide protrusion 323a provided on the second hinge cam and the hinge housings 330 and 340, and the linear second guide which moves in the state where the second guide protrusion 323a is inserted. This is due to the slits 332 and 342. The first-first hinge spring 322 is disposed between one end of the hinge housing and the second hinge shaft 321 to closely contact the second hinge shaft 321 to the second hinge cam 323. The close contact force provided by the second hinge spring 322 maximizes the sliding cam motion. The second-first hinge spring 324 is disposed between the second hinge cam 323 and the second hinge dummy shaft 325 to replace the second hinge cam 323 with the second hinge shaft 321. In close contact. The second-first hinge spring 324 is configured to be smaller than the elastic force provided by the first-first hinge spring 322 because the diameter of the first-first hinge spring 322 is small. The first-second hinge dummy shaft 325 is disposed to be in close contact with the other end of the hinge housing by the second-first hinge spring 324, and the shaft portion 325a protrudes from the other end of the hinge housing. Exposed. Thus, the shaft portion 325a is coupled to the folder. However, the shaft portion 325a only performs the coupling function with the folder and does not rotate together.

As shown in FIGS. 3 and 4, preferably, during the opening and closing process of the folder 20 in the main body 10, the folder 20 lifts the first hinge shaft A1 from the main body 10. The second hinge part 320 is constrained while being opened and closed by the first hinge part 310, and the folder 20 is moved from the main body 10 to the center of the second hinge axis A2. The first hinge portion 310 further includes a means 350 to be restrained while being opened and closed by the second hinge portion 320. The first hinge portion 310 includes a first hinge cam 313, the second hinge portion 320 includes a second hinge cam 323, the means 350 is the first, Two hinge cams 313 and 323 are formed between the first and second hinge cams 313 and 323 and are integrally connected and move together. That is, the means 350 moves in a direction parallel to the first and second hinge axes A1 and A2. The operation principle of the means 350 will now be described in detail.

When the first hinge shaft 311 rotates according to the rotation of the folder, the first hinge cam 313 is retracted by the sliding cam movement. Subsequently, as the first hinge cam 313 retreats, the means 350 also retreats together, and the second hinge cam 323 simultaneously moves in the same direction. Therefore, the coupling force between the second hinge cam 323 and the second hinge shaft 321 is further increased by the 2-1 hinge spring 322, so that only the first hinge 310 is operated. The second hinge part 320 is not operated. Here, when the rotation angle of the first hinge shaft 313 is about 90 degrees, the constraint force of the second hinge portion 320 is the strongest.

On the other hand, when the second hinge portion 320 is operated, the first hinge portion 310 is not operated for the same reason as the above reason. According to the principle of the first and second hinge parts 310 and 320, the opening and closing process of the folder is opened and closed in two steps. The folder is opened and closed within a predetermined angle about the first hinge axis A1, and then opened and closed at a predetermined angle or more about the second hinge axis A2.

As described above, the present invention can provide a hinge device that can implement a folder type and a bar type portable terminal. Therefore, it is possible to use a folder type or a bar type portable terminal selectively from the user's point of view, thereby satisfying the user's need for use. Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the present invention.
