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

The Lift Stop device includes an aluminum rod that is attached to a doorstop that is secured to a door for the purpose of lifting a doorstop from its down position to an up position.

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 vehicle locking apparatus for a vehicle using a coupling device for the separable connection of a vehicle door to a vehicle structure part, includes a first coupling element with two locking wedges mounted so as to be displaceable parallel to one another and having wedge faces. At least one of the locking wedges is formed with a locking nose on the wedge-side end face, and a second coupling element interacts with the first coupling element. The second coupling has two retaining jaws receiving the first coupling element therebetween with wedge grooves having wedge faces. The locking wedges are pushed via a driving device into the wedge grooves by separation of the wedge faces apart from one other and the locking nose is thereby received in a locking opening arranged in a wedge groove of a retaining jaw.

A door lock has a base, a wedge, and two pins. The base has an engaging end that has two holes and is wider than a base abutting end. The wedge extends upwardly from the. The two pins are configured to pass through the base holes and apertures in a floor surface to secure the base to the floor surface. An outermost edge of each of the base holes is laterally outside opposite sides of the wedge. In another embodiment, a door lock includes a base, a wedge, two pins, and a magnet. The base has an engaging end has two holes and is wider than a base abutting end. The pins are configured to pass through the base holes and apertures in the floor surface to temporarily secure the base to the floor surface. The magnet selectively biases the pins to the base when the base is not engaged.

A device for restricting movement of a door includes a door member, a floor member, and a connecting member. The door member is fixedly mounted to a door and includes a first opening having a first predetermined shape. The floor member is fixedly mounted to a floor and includes a second opening having a second predetermined shape. The connecting member includes a first leg and a second leg. The first leg extends in a first direction and has a first end removeably engaging the first opening. The second leg extends in a second direction that is perpendicular to the first direction and has a second end removeably engaging the second opening simultaneously when the first end removeably engages the first opening thereby preventing rotation of the door.

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.
