Abstract:
1. A slidable door lock brace apparatus mounted on an inside surface of a door, the apparatus comprising: a vertically mounted fixed plate attached to the inside surface of the door, the fixed plate having a groove about midway between a first and second side edge and below a top edge and above a bottom edge with an aperture at a lower portion of the plate and an upper portion of the plate on each side of the groove; a slide bar vertically mounted for movement within the groove; an upper gear housing attached to an upper portion of the fixed plate above the upper apertures; the upper gear housing containing a cam having a central axial bore, the cam rotating on a shaft turned by a lock key or a handle, the cam activating a spring to move the slide bar, the key axially turning a first gear to turn a second gear mounted on a top end of a vertically positioned threaded rod; a middle housing attached to the threaded rod so that turning of the threaded rod by the second gear causes the middle housing to move downwardly or upwardly; the middle housing having a lock clamp attached on an outer surface, the lock clamp having a pair of feet extending away from the middle housing to engage the apertures at either the upper or lower portion of the fixed plate and adapted to be disengaged from the apertures when the springs are activated by the cam; a bottom end of the threaded rod mounted on a top portion of a lower housing attached to the fixed plate at a lower portion-below the groove; a brace rod attached at a top end to the middle housing and contacting a floor surface at a second end in a deployed mode; and a pair of side hinges attached at a first end to the lower housing and at a second end to the brace rod.
