US Patent 7110802 Belt clip device for mobile communication terminal unit

A belt clip device is provided for a mobile communication terminal unit. The belt clip device includes a terminal unit holder for receiving and holding the terminal unit, a clamp provided on one side of the terminal unit holder and adapted to resiliently clip a belt worn by a user, thereby allowing the belt clip device to be mounted to the belt, and a connector for rotatably connecting the clamp to the terminal unit holder. The clamp includes a base portion, a panel portion hingably coupled at one end thereof to the base portion and spaced apart from the base portion to define a gap for receiving the belt therebetween, a spring adapted to urge the base portion and the panel portion in such a fashion that the gap is resiliently maintained, and a stopper provided at the other end of the panel portion and adapted to prevent the clamp from being separated from the belt. The connector includes a hinging member hingably coupled to the base portion of the clamp to hinge about a hinge shaft with respect to the clamp, and a rotating shaft for rotatably coupling the terminal unit holder to the hinging member in such a fashion that the terminal unit holder rotates about the rotating shaft with respect to the hinging member. By this configuration, the user can conveniently view a display window of the terminal unit without separating the terminal unit from the terminal unit holder.
