Abstract

An assembly of a notebook computer and a docking station includes a locking apparatus for locking the computer on the station. The apparatus includes a front retaining unit attached to the station and engaged within a front recess unit in the front end portion of the computer, and a rear retaining unit attached to the station and engaged within a rear recess unit in the rear end portion of the computer. In this situation, the computer is coupled completely with a connector unit on the station. Because the front and rear end portions of the computer are locked on the station by means of the retaining units which constitute a double lock, the computer cannot be removed forcibly from the station without disengaging the retaining units from the recess units. By operating an actuator unit on the base in a single action, a slide unit moves on the base so as to disengage the retaining units from the recess units at the same time and so as to disconnect the computer from the connector unit, thus unlocking the computer from the station. Then, the computer can be locked again on the station and coupled completely with the connector unit in a one-action operation on the actuator unit.
