<p>The present invention relates to a slide hinge interposed between a front surface unit and a main body unit of a slide opening/closing mobile phone to provide elastic force during slide opening/closing. The slide hinge is capable of effectively increasing actuating force and thus improving convenience for opening through a long stroke and change in a dead point. To overcome drawbacks, the present invention provides a slide hinge including a first elastic driving body and a second elastic driving body facing the first elastic driving body. The first elastic driving body includes a first spring which has a two-layer spiral portion and peripheral joint portions by being wound inwardly on a single plane into one layer about one end thereof and then wound outwardly on a single plane into the other layer upon arrival at a center thereof, and permitting both ends thereof to be gapped in different directions; a first rod having a first straight joint portion for accommodating and fixing one of the peripheral joint portions and a first device joint portion formed at a free end side of the first straight joint portion; and a second rod having a second straight joint portion for accommodating and fixing the other of the peripheral joint portions and a second device joint portion formed at a free end side of the second straight joint portion. The second elastic driving body includes a second spring which has a two-layer spiral portion and peripheral joint portions by being wound inwardly on a single plane into one layer about one end thereof and then wound outwardly on a single plane into the other layer upon arrival at a center thereof, and permitting both ends thereof to be gapped in different directions; a first rod having a first straight joint portion for accommodating and fixing one of the peripheral joint portions and a pin joint portion for joint with the first rod of the first elastic driving body, formed at a free end side of the first straight joint portion; and a second rod having a second straight joint portion for accommodating and fixing the other of the peripheral joint portions and a pin joint portion for joint with the second rod of the first elastic driving body, formed at a free end side of the second straight joint portion. The first elastic driving body and the second elastic driving body are jointed through pins such that the springs move elastically.</p> |
