Abstract
A restrictor device for restricting the extent of movement of a closure movably mounted with a frame. The restrictor device includes in combination an arm adapted for pivotal coupling to one of the closure member or frame and a latching member adapted for mounting with the other of the frame or closure member. The arm and latching members have cooperating elements which pivotally couple the arm with the latching member yet permits uncoupling of the arm from the latching member when the closure member is in a substantially predetermined position relative to the frame. The latching member includes a latch mechanism which prevents uncoupling of the arm when the closure is in the substantially predetermined position. There are operating mechanisms to enable the latch mechanisms to be operated such as to allow uncoupling of the arm to take place.
