1. A wireless charger comprising:
- a housing comprising an insertion hole through which a portable terminal is insertable into the housing;
a transmitting coil configured in the housing;
a pair of laterally spaced side supports in the housing; and
a bottom support in the housing disposed to move lengthwise of the housing and support a portion of the portable terminal when inserted in the housing,wherein the side supports are mechanically linked to the bottom support such that movement of the bottom support is coordinated with separate movement of the side supports, andwherein a side support of the pair of side supports is configured to laterally move within the housing in response to the portable terminal being inserted into the housing and to an extent for aligning a receiving coil of the portable terminal with the transmitting coil.

Abstract
A wireless charger optimized for charging efficiency of portable terminals (e.g., mobile phones) of different sizes has a housing including within it laterally spaced side supports and a bottom support for cradling an inserted portable terminal. The side supports and the bottom support are interlocked for coordinated movement such that the bottom support is moved by a predetermined amount according to movements of the side supports. This arrangement optimizes relative placement of the charger'"'"'s transmitting coil and the portable terminal'"'"'s receiving coil.

5. A wireless charger comprising:
-
a housing comprising an insertion hole through which a portable terminal is insertable into the housing; a transmitting coil in the housing disposed to face a receiving coil of a portable terminal when the portable terminal is inserted into the housing; a pair of laterally spaced side supports in the housing disposed to move laterally toward and away from each other on opposite sides of an inserted portable terminal; and a bottom support in the housing disposed to move lengthwise of the housing and support a portion of the bottom of the inserted portable terminal, wherein the side supports are mechanically linked to the bottom support such that movement of the bottom support is coordinated with movement of the side supports, wherein the bottom support comprises two separate bottom support portions and each side support is connected to a respective bottom support portion to form two support assemblies, wherein movement of each support assembly is guided by a guide protrusion slidably engaged with a guide rail inclined with respect to the side supports and the bottom support, and wherein each support assembly carries one of the guide protrusion and the guide rail, and the housing carries the other of the guide protrusion and the guide rail. - View Dependent Claims (6, 7)

21. A wireless charger comprising:
-
a housing comprising an opening through which a portable terminal is insertable into the housing; a transmitting coil configured in the housing; a support disposed in the housing and configured to move, in response to the portable terminal being inserted into the housing, toward either one or both of a side wall of the housing and a bottom wall of the housing to cause a facing of a receiving coil of the portable terminal with the transmitting coil; and a guide protrusion configured to slide along a guide rail in response to the movement and extending from either one of the support and another side wall of the housing.
