Patent ID: 7412751

Claim:
A doorstop comprising: a unitary body made of a resilient material, the body including: an elongate shank having a longitudinal axis, wherein the length of the elongate shank is sufficient to engage a plane of a door while preventing a door knob on the door from contacting a wall to which the doorstop is mounted; an air chamber having one closed end and one open end, the air chamber extending axially into the elongate shank to dampen the impact of the door along the longitudinal axis; a base at one end of the elongate shank; a plurality of air passages in the base communicating with the air chamber enabling air to exit the air chamber when the elongate shank is axially compressed and to enter the air chamber when the elongate shank returns to its normal position; and a flexible wall connecting said elongate shank to said base and configured to flex along the longitudinal axis in response to an impact by a surface of a door to absorb the impact of said door, and along a lateral axis substantially perpendicular to the longitudinal axis in response to lateral forces.
