A wire crate latch apparatus having, in a first embodiment, a pivoting member that is continually drawn to a closed position by gravity and that is deflected into a catch when the door having the pivoting member is swung closed. The latch apparatus further includes upper and lower stops to contain a distal end of the pivoting member and to hold the distal end in the position to hit an oblique portion of the catch when the door is closed. In a second embodiment, a sliding latch apparatus is deflected by a catch and is relatively inaccessible from inside of the wire crate by back plates on the latch and catch.

A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a swinging door or endwall of a sliding door. A second end of the securement device is configured to be engaged with a support surface adjacent the door, to prevent opening of the door in a direction toward the engaged member.

Methods and apparatus for using a look on a door lever handle are disclosed. The lock includes a base configured to mount the lock to a door having a lever handle and a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position. The lever handle guard is securable in the non-locking position. The lever handle guard includes first and second guard portions arranged to prevent rotation of the lever handle when the lever handle guard is in the locking position. When the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle without contacting the first and second guard portions.

The door viewport with cross-door locking bar laterally spans the door frame with a viewport exterior lip on the door and an interior face plate near an interior of the door forming, in one instance, a mid-bar capture channel. Alternatively, the viewport has an interior extension coacting with a complementary interlocking element on the cross-bar's midpoint. Either construct holds the cross-door locking bar substantially at its mid-point. Cross-bar terminal end mounts removably attach the cross-bar to the door frame. One type of mount is an L-bracket. Another type of mount is a controllable transverse extension member forcing a door frame plate against the door frame. A user-controlled extension means forces the cross-door locking bar away from the door frame plate, with either a screw drive system or a grooved rod with spring loaded lever control.

A door prop includes a rectangular wedge secured horizontally by a first elastic cord in a horizontal position adjacent the door frame upon a door when the door is open. A second elastic cord enables a user to move the wedge away from propping the door when the door is desired to be closed.

A lock assembly is provided for a window having a first sash and a second sash. The lock assembly comprises an elongate strip configured to be coupled to the first sash. The elongate strip has a plurality of recesses defined along a length of the elongate strip. The lock assembly also includes a lock member configured to be coupled to the second sash and operable to move along the length of the elongate strip. The lock member includes a biasing member and a coupler biased in a direction of the elongate strip by the biasing member. The coupler is configured to enter each of the plurality of recesses to selectively lock the lock member to the elongate strip.

A portable door securement device is provided having a member extending from a first end engaged to a doorknob of a door to a second end engaged with a floor adjacent the door, to prevent opening of the door in a direction toward the engaged member. A slot at a first end of the member engages around a stem of the door handle thereby preventing disengagement of the member from the door, and preventing opening of the door.
