| 20110111812 | SWING TYPE COVER OPENING AND CLOSING DEVICE FOR MOBILE PHONE - According to an exemplary embodiment of the invention, a swing-type cover opening and closing device for a mobile phone, in which in which the mobile phone that is composed of a main body and a cover and where a hollow shaft formed in the cover is pivotably supported on the main body to pivot the cover in a clockwise or counterclockwise direction around the hollow shaft, includes: i) a fixation plate that is fixed to one side of the main body in correspondence with the hollow shaft, and includes a through-hole through which the hollow shaft passes and a ring-shaped protrusion integrally formed on the periphery of the through-hole; ii) a rotating body that has a disk shape with a hollow space, is pivotably joined to the ring-shaped protrusion, and is locked to the cover with the hollow shaft fitting in the hollow space; iii) a cover member that includes a support hole corresponding to the hollow space and is joined to the fixation plate while supporting the outer periphery of the rotating body through the support hole; and iv) an elastic unit of which both ends are pivotably joined to the fixation plate and the rotating body, respectively, to provide elastic force to the rotating body by rotation of the rotating body through the cover. | 05-12-2011 |
| 20110078876 | Hinge device for mobile device of folding type - A hinge device for a mobile device of folding type has a first body being a main body and a second body being a cover. The second body is rotatable with respect to the first body upwardly or downwardly. The hinge device is connected to a first hinge arm formed at one side of an upper end of the first body and a second hinge arm at the other side of an upper end of the second body. The hinge device may include a first hinge bracket provided with a first case portion inserted in the first hinge arm, and fixedly mounted to the first body; a second hinge bracket provided with a second case portion inserted in the second hinge arm, and fixedly mounted to the second body; a hinge shaft fitted in the first case portion, inserted in the second case portion, stopped by an interior surface of the first case portion, and fixed to the second case portion by an engage unit; a bushing unit disposed between the first case portion and the second case portion, fixed to the interior surface of the first case portion, rotatably inserted in the second case portion, and formed of an stopper portion for liming rotating range of the second body to the first body; and a hinge module disposed in the first case portion and transmitting driving torque to the second body through the hinge shaft in a case that the second body rotates. | 04-07-2011 |
| 20110072922 | SLID TYPE COVER OPENING AND SHUTTING DEVICE FOR MOBILE PHONE - A slide-type cover opening and shutting device for a portable terminal according to an exemplary embodiment of the invention includes: a plate-shaped guide member; a plate-shaped movable member that is slidably assembled to the guide member, and an elastic member of which ends are rotatably connected to the guide member and the movable member, respectively. The elastic unit includes: i) a pair of rotary plates that cross in parallel with each other and are rotatably connected to the guide member and the movable member by hinge pins; ii) elastic support plates that are connected to both sides of the rotary plates between the rotary plates to be able to slide and lock, composed of first and second slide sections that are open to opposite directions toward the rotary plates, and that have a plurality of support pins that are partially inserted in the rotary plates at the first and second slide sections; and iii) elastic members that are fitted on the support plates and apply elastic reaction force to the rotary plates. | 03-31-2011 |
| 20100071159 | HINGE TYPE COVER OPENING AND CLOSING DEVICE FOR MOBILE PHONE - A hinge-type cover opening/closing device is designed to smoothly open and close a cover by preventing sudden rotation of the cover. The hinge-type cover opening/closing device for a mobile device includes a pair of hinge shafts, a pair of guide members that are fixedly installed on the hinge shafts, spaced apart from each other by a predetermined distance in a length direction of the hinge shaft, and that enable the hinge shafts to rotate about each other, and one or more cam actuating units that are installed on the hinge shafts, spaced apart from each other by a predetermined distance in the length direction, and that enable the hinge shafts to rotate about each other within a predetermined angle range. | 03-25-2010 |
