ABSTRACT:
A doorstop having a housing contains a striker block slideably mounted in the housing. The striker block is biased in a first position where it engages a spring loaded door restraining member holding the door restraining member in a down position. When the striker block is moved into a second position against its biasing force, the striker block disengages the spring loaded door restraining member and the door restraining member is urged into an up position. A force applied to the door restraining member sufficient to overcome the spring and biasing forces, will return the door restraining member to its down position, the biasing force will return the striker block to its first position and engage the door restraining member and hold it in the down position.
