- the pre-stop function is performed by the tension mechanism 50 when the rotational positions of the first and second main bodies 11 and 12 are between the 'expanded position' and the 'folded position' do.
- the tension guide projections 58b of the first and second tension wings 55 and 56 are the tension guide holes of the first and second hinge wings 21 and 22 Since it is guided by (58a), when the first and second hinge blades 21 and 22 rotate, the first and second tension blades 55 and 56 interlock and rotate together.
- the tension movable member 53 and 54 is rotated by the rotation of the first and second tension wings 55 and 56. While the inclined projections 55a, 56a, 55b, and 56b of the first and second tension wings 55 and 56 are separated from the inclined projections 53a, 53b, 54a, and 54b of the ), the tension movable members 53 and 54 are separated. It is moved by pressing in the direction of the hinge axis (see Fig. 13b).
- the tension movable members 53 and 54 move along the first and second guide shafts 52a and 52b to compress the first and second springs 57a and 57b, so that the tension movable members 53 and 54 ) to the first and second tension blades 55 and 56, the elastic force of the first and second springs 57a and 57b is increased, and the increased elastic force causes the first and second bodies 11 and 12 to When stopping during rotation, it can perform a free stop function to keep it at the stop position.
- the hinge device of the present invention described in detail above can be used in various devices to which a folding hinge structure is applied, such as a laptop computer, in addition to a portable terminal such as a mobile phone.
