ABSTRACT:
A door lock device having an indoor and outdoor housing, each having inner tube-shaped supports, and further including indoor and outdoor handle connection members, each having at a first end handle connections with an indoor and an outdoor handle, respectively, and having at a second end opposite the first end driving cams formed with a cam curvature having step differences in an axial direction. Indoor and outdoor slide cylinders are provided having driven cams in contact with the driving cams and experiencing a rectilinear motion in the axial direction by means of the axial step difference. A first coupling spring is fixed to the indoor handle connection member and the indoor slide cylinder. A second coupling spring is fixed to the outdoor handle connection member and the outdoor slide cylinder. Indoor and outdoor end frames allow the indoor and outdoor slide cylinders to be guided rectilinearly in the axial direction by means of a rectilinear guide fitting. A guide frame located between the indoor and outdoor end frames includes an operating piece supported by a door lock spring, the operating piece being connected to the door lock unit. Indoor and outdoor rotary pieces are positioned to experience a rotational motion with the indoor and outdoor end frames by means of first and second pins, and having a sliding rotational motion by means of the indoor and outdoor slide cylinders.
