A magnetic doorstop. The magnetic doorstop includes a plate that can be mounted on a surface, such as a door. An arm extends from the plate at a hinge and can be pivoted about the hinge such that the arm can occupy an up position and a down position. A first end of the arm engages with a floor in the down position. While engaged with the floor, the first end of the arm prevents the door from moving. A magnet is disposed on the plate in line with the arm. The arm can magnetically secure to the plate in the up position.

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.

Embodiments discussed herein enable an authorized user of a door security device to secure a door against entry, but also enable that authorized user to provide access to others, without having to provide a physical key. Embodiments discussed herein further allow an authorized user to operate the door security device remotely, such as through a wired or wireless network, or through any other network as described herein, as known at the time of filing, and/or as developed after the time of filing.

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.

Locking apparatuses and methods are provided for controlling access to a space using an improved locking apparatus. The locking apparatus includes a body, an actuator, and a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to a command position. The locking apparatus further includes a lifting mechanism configured to receive an output of the actuator and to raise or lower the lifting member responsive to the actuator output, and an adjustment member configured to contact the body and the lifting member. A manual operation-based locking apparatus is provided which uses a foot pedal to lock or unlock the locking apparatus. A method is provided for operating a mounted locking apparatus in a locked or unlocked state.

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.

A door stopping system comprises a mounting member, a supporting member, a leg member, a spring member, a sleeve member, a first pin member and a second pin member. The mounting member is pivotally connected with the supporting member via the first pin member, the leg member is pivotally connected with the supporting member via the second pin member, the mounting member and the leg member are oppositely located to each other along the supporting member, the spring member is biased in between the supporting member and the leg member, and the sleeve member is slidably sleeved on the supporting member. The mounting member is configured to be removably attached to a door. The leg member is configured to contact a ground.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a mounting bracket, a central member, a stop plate, and a housing. The mounting bracket is couplable to the openable element. The central member is couplable to the mounting bracket and includes a body, an actuator, a lifting member coupled to the body and configured to be raise or lowered. The stop plate may be coupled to the frame of the openable element and aligned with at least a portion of the lifting member for restricting movement of the openable element when the lifting member is raised. The housing may be coupled to the mounting bracket and is generally used for aesthetic purposes. The locking apparatus may be one of a plurality of locking apparatuses grouped together for singular or group control, such as, for active shooter situations.

A low-profile door barricade can be deployed rapidly from within a room, such as a classroom, to prevent entry by an assailant. The barricade may include quick release and locking mechanisms that are inaccessible to the assailant and can only be operated from within the room.

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.
