Patent attributes
A door security device for preventing opening of a door. A first device includes a bar that seats against a doorframe on opposite sides of the door and a clamp that clasps a door latch and applies a force to draw the bar against the doorframe while pulling the door latch toward the bar. The door cannot be opened away from the bar. A second device has a bar that seats against a doorframe at the floor with a two plates that extend beneath the door and around to opposite sides of the doorframe. Removable pins or other locks obstruct the plates from sliding along the bar. The bar is tall enough that the door cannot pass over the bar, thus obstructing the door from opening inwardly. A closer cover slides over a mechanical door closing mechanism to be used alone or with the other devices.
