    Abstract: A rocking doorstop comprises a base portion having a lower surface for placement on a surface in proximity to a door. A first arm is coupled to the base portion such that the first arm is configured to engage a door as a result of motion of the door in a first direction. A second arm is also coupled to the base portion, wherein the second arm is configured to engage the door as a result of engagement of the first arm with the door. The engagement between the first and second arms and the door retains motion of the door in the first direction. The first arm is generally configured to engage the front surface of the door. The second arm is configured to engage the bottom surface of the door via a rocking motion created by the door engaging the first surface.
