Abstract: A portable door lock is provided for a door having a latch engageable in an aperture in a latch plate secured to a door frame, the latch plate having a tongue extending into the aperture from a front edge of the latch plate, and the tongue being spaced from the top and bottom of the aperture. The door lock includes a retainer positionable against the latch plate to permit closing of the door and having a pair of vertically spaced fingers insertable into the latch plate aperture to engage the front edge thereof above and below the latch plate tongue. A retainer shaft extends forwardly from the retainer and has a screw-thread portion, and a holding bracket has a medial portion slidably mounted on the shaft and rearwardly projecting holding arms at opposite ends.

Abstract: A door securer includes a generally U-shaped member that is adapted to be mounted on the side of a door that opens, as opposed to the side that is hinged. The inside leg of the U-shaped member is pivotably connected to a leg member that has a foot member pivotably mounted thereon remote from the universal joint. In situ, the leg member extends downwardly from the U-shaped member at an acute angle to the door, and the foot member engages the floor behind the door.
