The present invention is a door barricade having a pivoting locking arm which drops into a floor hole to lock a barricade in place.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to an output of the actuator, the lifting member comprising a contact surface configured to restrict movement of the openable element, and a strap coupled to the body and to the lifting member, the strap configured to permit the lifting member to flex based at least in part upon contact between the lifting member and the openable element and to transfer energy received at the lifting member into the body of the locking apparatus into a surface to which the locking apparatus is mounted.

The present invention is a door barricade having a pivoting locking arm which drops into a floor hole to lock a barricade in place.

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.

A device can include a door member mounted to a swinging door, a connector, and a fastener. The door member can include a slot open at the top and bottom and an outer face. A bore through the door member can align with a bottom of the slot. A first end of the connector can slide into the top of the slot so a first leg extends through the outer face and a second leg overlaps the soffit. When a fastener is in a first position, the fastener can extend through a bore in the door member and support the connector in the slot and block the connector from exiting the slot through the bottom. When the fastener is in a second position, the fastener does not block the slot and the connector is permitted to drop out of the slot through the bottom.

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.
