Patent ID: 8276240

Claim:
A door check for use in selectively maintaining a predetermined gap between a door closing face and a door frame, said door check comprising: a base including an attachment element for securing said door check to said door, said base further including journal block elements; said door check further including an action arm with a distal end and a proximal end, said action arm pivotally mounted near its proximal end in said journal block elements; said action arm proximal end is further defined as having an arcuate portion terminating at a corner; said action arm further including sockets defined along said arcuate portion adjacent said corner; a spring biased ball detent within said base biased against said arcuate portion and arranged to engage said sockets to at least two positions; a first of said sockets defined on said arcuate portion is configured to engage said ball detent to place said action arm in a door checking position where said arm is pivoted upwardly relative to said base to serve as a door check; a second of said sockets is configured to engage said ball detent such that said action arm is pivoted slightly downwardly relative to said base so as to assume a trigger re-set position wherein said corner protrudes beyond said journal block; whereby external interference with said protruding corner biases said action arm toward the door checking position.
