ABSTRACT:
A door security device includes an elongate support bar, attachment mechanism mounted to the support bar, opposing blocking members attached to opposing ends of the support bar, and an actuation mechanism. The attachment mechanism includes a pair of generally J-shaped hooks which engage a portion of a door. The blocking members include a surface thereon which rests flush against the door frame. The actuation mechanism includes a handle assembly which is pivotally connected to the hooks. The handle assembly includes a camming surface thereon which contacts the support bar. The security device is actuated by positioning the hooks about the door and positioning the blocking members flush against the door frame. The handle is then pivoted, causing the camming surface to pivot about the support bar and pull the hooks away from the door and towards the support bar.
