As shown in FIGS. 16 and 19, the first and second rollers 435a and 435b are obliquely slid by the guide roller grooves 432a, and the guide holes 431b of the first guide sliding part 431 are slidably moved in a downward direction along the guide pin 500 mounted at the second guide sliding part 432.
Referring now to FIG. 18, the first and second rollers 435a and 435b come out of the engaging grooves 432c formed at one end of the guide roller grooves 432a, are obliquely slid and then inserted in the stopper grooves 432d formed at the other end of the guide roller grooves 432a, in which the sliding movement of the first and second rollers 435a and 435b in the oblique direction is restricted. At this point, the swing plate 421 can be obliquely slid together with the first guide sliding part 431 and further moved in a downward direction along the hinge axis A1, and the slide hinge part 430 and swing housing 300 are also moved together.
As shown in FIG. 15, the swing housing 300 and the body housing 200 are juxtaposed, i.e., arranged in parallel at the same angle without a height difference.
Here, the second display 301 of the swing housing 300 shown in FIG. and the first display 201 of the body housing 200 are similarly arranged in parallel at the same angle without a height difference therebetween, which makes it possible to maximize the size of the first and second displays 201, so as to be used as a touch screen or a keypad.
From this state, as shown in FIGS. 5 to 9, in order to return the swing housing 300 to its initial position, the hinge housing 410 together with the swing housing 300 is moved upwards along the direction of the hinge axis A1.
As shown in FIG. 9, the slide hinge part 430 is then moved in an upward direction and at the same time obliquely slid.
Referring now to FIGS. 6 and 7, the protrusions 435d of the first and second rollers 435a and 435b are guided in a right to left direction in the guide roller holes 431a formed at the first guide sliding part 431.
At the same time, as shown in FIG. 9, the first and second rollers 435a and 435b are obliquely slid and then moved upwards by the guide roller grooves 432a formed at the second guide sliding part 432.
As shown in FIGS. 6 and 9, the first and second rollers 435a and 435b are obliquely slid by the guide roller grooves 432a, and the guide roller holes 431a of the first guide sliding part 431 are slidably moved in an upward direction along the guide pin 500 received in the second guide sliding part 432.
Referring now back to FIG. 6, the first and second rollers 435a and 435b come out of the stopper grooves 432d of the guide roller grooves 432a, obliquely slide to move upwards, and then engage with the engaging groove 432c of the guide roller grooves 432a, in which their sliding movement in the oblique direction is restricted.
At this point, as shown in FIG. 7, the elastic member 434 of the slide hinge part 430 is slid in a right to left direction of the first guide sliding part 431 and then compressed. At the same time, the swing plate 421 along with the first guide sliding part 431 is also obliquely slid and moved in an upward direction.
As shown in FIG. 5, the swing housing 300 is rotated about the hinge axis A1 and returned to its initial position, facing the body housing 200.
Here, as shown in FIG. 7, since the swing hinge member 423 is provided with the stopper 426, the stopper 426 is disengaged from the second contact stopper 421b and then comes into contact with the first contact stopper 421a, thereby restricting the swing movement of the swing plate 421. At this moment, the hole 425a formed at the swing plate 421 is also swung to its initial position and then disengaged from the locker 425b provided at the swing hinge member 423.
While the invention has been shown and described with reference to certain exemplary embodiments of the swing-type portable communication apparatus and the hinge mechanism thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
