Abstract: Disclosed herein is a locking apparatus of a swing hinge module for mobile communication terminals that is capable of improving a locking force of the swing hinge module, the mobile communication terminal including first and second housings rotatably connected to each other by the swing hinge module. The swing hinge module includes a locking apparatus having a hinge cap extending in the longitudinal direction thereof and having a closed end formed such that a head of the hinge shaft is inserted through the closed end of the hinge cap and an open end formed such that the hinge cap is attached to the hinge housing while the hinge cap surrounds the outer circumference of the hinge housing through the open end of the hinge cap, and a hinge fixing plate engaged with the head of the hinge shaft while opposite to the hinge cap such that the hinge housing and the hinge cap are fixed to each other by means of the hinge fixing plate while being rotated relative to the hinge fixing plate.

Abstract: A hinge guide apparatus of a swing-type portable terminal which can prevent deflection of a hinge module when the battery pack of the portable terminal is attached or detached is provided. The swing-type portable terminal having a body housing to and from which a battery pack is attached and detached, a swing housing rotating about a hinge axis vertically extending in a front surface of the body housing, and a hinge module having first and second hinge cams, a hinge shaft, and a swing plate to rotatably connecting the swing housing to the body housing.

Abstract: Provided is a multi-charging device and method by which a plurality of portable-device batteries can be charged simultaneously. The multi-charging device includes charging terminal connector including a socket to receive power from an external source and a plurality of charging terminals. Each charging terminal is connected with the charging terminal connector, and the charging terminals deliver the power from the socket of the charging terminal connector to a portable device connected therewith.

Abstract: A sliding swing apparatus for a mobile terminal is disclosed that provides a swing movement after a complete sliding movement. A sliding member is adapted to slide along the longitudinal direction and then to rotate once sliding movement is fully extended. A sliding movement means enables the sliding member to slide, a swing member is adapted to rotate together with the sliding member. A third guide means guides the rotation of the swing member via a rotation means. A swing locking apparatus stops rotation, by bringing the swing member and the third guide means into contact and then allows for rotation.

Abstract: A hinge apparatus for coupling a pair of housings of a portable terminal to each other so that the housings can rotate and unfold from each other. The apparatus includes first sun gears coupled to the housings, respectively; second sun gears positioned between the first sun gears so as to interlock the first sun gears; and a stopper unit connected to at least one of the first and second sun gears and adapted to suppress rotation of the first and second sun gears, when the housings are folded on each other while facing each other, so that rotation of the housings is limited.

Abstract: A portable, foldable cradle for portable terminals is provided. The foldable cradle includes a cradle body, a cradle support folded or unfolded with respect to the cradle body, a hinge unit provided to the cradle body and rotatably coupling the cradle support, and a means that is provided to the cradle body, brought into direct contact with a predetermined part of the portable terminal to prevent the contacted portable terminal from sliding in a ground direction, and adjusts a cradled state of the portable terminal.

Abstract: A hinge device in a mobile terminal having a first housing and a second housing. The hinge device includes: a hinge housing mounted to the second housing; a cam housing received in the hinge housing to be linearly movable and having a stopper protruded outward from the hinge housing; a drive component received in the hinge housing and generating a rotation force acting in a direction that the second housing is getting away from the first housing within a predetermined range of rotation; and a hinge dummy mounted to the first housing and having a stopper groove for restricting the movement of the stopper. The second housing stops rotation at least one time by the interruption of the stopper and the stopper groove within a full range receiving the rotation force acting in a direction to be away from the first housing.
