Patent ID: 8776316

Claim:
A device for preventing slamming of a door in a door frame, the device comprising: a mounting member having a mounting surface configured to be coupled to one of a vertically-extending surface of the door and a vertically-extending surface of the door frame; a blocking member movably engaged with the mounting member, the blocking member being movable relative to the mounting member in at least a first direction between a first extended position and a second retracted position along the first direction; and a control member movably engaged with the blocking member, the control member being movable in at least the first direction from a home position to a displaced position relative to the blocking member upon contacting with the other one of the surface of the door and the surface of the door frame during closing of said door, wherein the movement of an attempted closure of the door at a first velocity above a threshold velocity causes the control member to move at least initially to the displaced position relative to the blocking member while the blocking member remains at least temporarily in the first extended position such that the blocking member prevents complete closure of the door, and wherein the movement of an attempted closure of the door at a second velocity below the threshold velocity causes both the control member and the blocking member to move substantially simultaneously in the first direction until the blocking member is in the second retracted position such that the blocking member does not prevent the door from closing.
