ABSTRACT:
A door guard for a swingable door that is mounted in a doorway having a door closer affixed to the doorway permits the door to open beyond the point which would normally be the widest open position allowed by the door closer and slows the rate of movement of the door so as to prevent damage to the door, door closer, or doorway. The door guard includes a flexible resilient arm extending transversely across the inside of the door and connected to the door closer at a point intermediate its ends, said arm is anchored at its inner end to the door and has its outer end releasably attached to the door, and catch means mounted on the door for releasably attaching the outer end of the arm to the door. When a force such as a gust of wind causes the door to fly open, such that the door closer reaches its fully extended position, the outer end of the arm is released by the catch means and the arm flexes to permit the door to continue opening. The further opening of the door is slowed by the resistance of the arm to flexing thus preventing damage to the door, door closer or doorway. The resistance may be provided by the inherent resiliency of the arm itself or by some other resilient member, such as a coil spring secured between the arm and the door.
