A right-angled triangle barricade for a door it is not directly connected to. The right-angle barricade is pivotably mounted to a supporting surface, such as a wall or ceiling, adjacent to the door to be barricaded. The right-angle barricade is pivotably movable from an inactive orientation, where its profile is flush against the supporting surface and not in the swing path of the door, to an active orientation where its profile is normal to the door and forces imparted on the door are transferred to be normal against the supporting surface.

A door brace (10) comprising: an engagement member (12) comprising a bottom flange (14) comprising one face comprising a textured surface (14a) to engage with a door (34); an angled leg (20) comprising a first section (22) hingedly connected at one end to the wall and a second section (23) extending from the first section at a first angle, the leg being movable between a stowed position and an extended position in which the first section makes a second angle, larger than the first angle, to the wall; an engagement foot (26) pivotably mounted on a mounting element (24) having an adjustable length; and a hinge stop configured to prevent the leg moving beyond a maximum extended position. Wherein, in an extended position, the second section of the leg extends at a third angle to the wall equal to the difference between the second and first angles and the engagement foot causes a clamping force to be applied to the door.

The present invention relates to a portable safety door stopper and a room door blocking method. The portable safety door stopper comprises a stopper for attaching to the inner side of a door, a base laid flatwise on the ground, and a supporting post rotatably connected between the stopper and the base, wherein a locking hook component is built in the stopper, and the stopper can always cling to a set position on the inner side of the door through the locking action of the locking hook component, so that the installation of the safety door stopper is realized; an alarm module can be built in the base to achieve an alarm reminding function at the same time.

A door stopper device having a base securable to the floor adjacent to the door, and a stepper plate pivotally attachable to the base. A stopper plate is pivotally attached to the base and the stepper plate, with the stopper plate having a distal end portion opposite the stepper plate. The distal end portion of the stopper plate is raised upward and is engageable with the door when the door stopper device is in an engaged position, and the distal end of the stopper plate is lowered from the engaged position to assume a disengaged position, the stopper plate is not engageable with the door when the door stopper device is in the disengaged position.

Apparatuses, systems, and methods are provided for restricting movement of an openable object including 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 using the actuator to selectively restrict movement of the openable object, and a control circuit including a transceiver configured to receive a requested operation, the control circuit configured to process the requested operation and to control the locking apparatus responsive to the requested operation to place the locking apparatus in a locked or an unlocked state.

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 door brace (10) comprising a door engagement member (12), a leg (20) and an engagement foot (26). The door engagement member (12) comprises a bottom flange (14) for location under a bottom edge of a door (34) and an engagement wall (16) having one face (18) for location against one side of the door. The leg comprises a fixed length section(22)and an adjustable length section (24). The leg is hingedly connected to the engagement wall and is movable between a bracing position in which it extends at a first angle to the engagement wall and a released position in which it extends at a smaller angle to the engagement wall. The door brace has a released condition in which the leg is in the released position and the adjustable length section of the leg has a first length and a bracing condition in which the leg is in the bracing position and the adjustable length section of the leg has a longer length.

A door stop rod assembly includes a base having a room defined therein. A neck and a yoke are respectively connected to two opposite ends of the base. The collapsible part is connected to the neck. The yoke includes a notch against which the door knob contacts. A warning device is located in the room of the base and includes a circuit, a power supply, a buzzer, a vibration detector, a static electricity sensor and a switch. When the vibration detector detects vibration from the door knob due to exterior touch of the door knob, the circuit activates the buzzer to warn the persons inside the house.

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 device for slowing or stopping a door from opening or moving may include a base designed to be attached to the door, the base including a magnet mounted thereto; and a spring loaded blade hingeably attached to a bottom portion of the base, the spring loaded blade having a proximal flat end and a distal pointed end, wherein the blade is configured to pivot from a first closed orientation to a second deployed configuration. When the blade is in the first closed orientation the blade is engaged with the magnet on the base, and when the blade is in the second deployed configuration, the blade is disengaged from the magnet and the distal pointed end is pointing at an angle downward from the base.
