Patent ID: 8544896

Claim:
A stop device comprising, in combination: a stop including a base having first and second surfaces spaced along a first axis, with the base further including first and second lateral surfaces spaced along a second axis perpendicular to the first axis, with the base further including a first wing extending away from the first surface of the base along the first axis, with the first wing including a lateral face spaced from the second lateral surface of the base along the second axis, with the first wing further including upper and lower faces spaced along a third axis perpendicular to the first and second axes, with the first wing further including a catch extending from the upper face to the lower face of the first wing, with the catch including a stop face connected to the lateral face of the first wing, with the stop adapted to be mounted to an inner face of a door frame with the second surface of the base facing the inner face of the door frame; a limiting member mounted to the first wing, with the limiting member adapted to be releasably engaged with a latch of a panic exit door lock mounted to a door that is pivotably mounted to the door frame, with the latch stopped by the limiting member when the door is closed and abuts the door frame and when the latch is in an extended, latching position, with the door being openable when the latch is in a retracted, unlatching position; an engaging member including first and second lateral faces spaced along the second axis, with the engaging member further including a tongue extending away from the first lateral face of the engaging member along the second axis, with the tongue further including first and second faces spaced along the first axis, with the engaging member adapted to be fixed to the door, with the tongue located between the inner face of the door frame and the catch when the door is in a closed position with the first face spaced from the stop face of the catch along the first axis, wherein when the door deforms and moves away from the inner face of the door frame along the first axis, the first face of the tongue abuts the stop face of the catch of the stop, preventing the latch from disengaging from the limiting member to prevent opening of the deformed door.
