Abstract A door jammer device for preventing opening from the outside of a inward-opening door is disclosed, comprising a substantially U-shaped member having a shorter arm, a longer arm, and a base. Screw means are installed though a threaded hole through the longer arm towards the shorter arm, for attaching the member to the door by clamping the door between the screw means and the shorter arm. A jamming member is pivotally attached to the longer arm and angles downwardly away from the U-shaped member to engage the floor. Thus, a door may be locked by tightening the screw means to clamp the device to the outside edge of the door near the floor, such that the jamming member engages the floor. The jamming member has downwardly protruding teeth at its floor-engaging end, and angles downwardly at an angle of approximately 15 to 20 degrees from the horizontal.
A door jammer device for attachment to the outside edge of a door near the floor, for preventing opening from the outside of an inward opening door, comprising: a substantially U-shaped member having a shorter arm, a longer arm, and a base; screw means installed through a threaded hole through said longer arm towards said shorter arm, for attaching said member to said door by clamping said door between the screw means and said shorter arm; and a substantially L-shaped jamming member having a vertical arm and an arm which angles downwardly at an angle of approximately fifteen to twenty degrees to the horizontal; where said vertical arm is pivotally attached to said longer arm of the U-shaped member, for pivoting about a horizontal axis perpendicular to the plane of said door, and said horizontal arm of said jamming member angles downwardly away from said U-shaped member to engage the floor; whereby said door may be locked by tightening said screw means to clamp the device to the outside edge of the door near the floor, such that the jamming member engages the floor.
