Patent ID: 8496278

Claim:
A portable device for preventing movement of a door, the device comprising: an L-shaped support frame comprising a vertical portion and a base portion, the vertical portion and the base portion being substantially planar; a hardened bent area defined on the support frame at a position where the vertical portion and the base portion meet to increase a strength of the support frame; a continuous aperture defined within the vertical portion and the base portion of the support frame; and a leg pivotally connected to the vertical portion of the support frame, the leg having an upper portion connected to a lower portion of the leg at an obtuse angle, and at least the lower portion of the leg is movable to a retracted position by movement through the aperture to abut against the base portion; wherein a height of the leg is adjustable relative to the ground by manual finger rotation of an exterior tubular member surrounding the lower portion of the leg, and an embedded screw within the exterior tubular member that is in screw engagement with an internal screw thread within the upper portion of the leg for enabling incremental movement of the exterior tubular member relative to the leg; and wherein a distal end of the lower portion of the leg is made to contact the ground when at least part of the base portion is in contact with a bottom surface of the door in order to prevent movement of the door.
