Patent ID: 8632116

Claim:
A door for closure of an entryway, the door comprising: an exterior-facing surface; an inner structure; a latch mechanism connected to the inner structure, configured to be fastened such that the door maintains closure of the entryway, and capable of being released such that the door opens the entryway; a key-cylinder attached to and accessible from the exterior-facing surface, and adapted to selectively lock and unlock the latch mechanism; a pawl attached to the key-cylinder and operatively connected to the latch mechanism, such that the pawl is rotated by the key-cylinder to unlock the latch mechanism; a feature arranged on the inner structure and aligned with the key-cylinder; and a rigid stud connected to the key-cylinder and extending through the pawl, the stud being aligned with and extending into the feature without contacting the inner structure; wherein the stud is configured to not impede the rotation of the pawl when the stud is aligned with the feature, and configured to restrict angular movement of the key-cylinder with respect to the door when the key-cylinder is forcibly manipulated, thereby causing the stud to contact the inner structure.
