ABSTRACT:
A portable door lock having a base which can be attached to or inserted in a door jamb to extend therefrom into a room to be locked. An arm is attached to the base and is biased to a retracted postion where the door is free to swing open. The arm can be moved against the bias to a postion where the door is blocked from swinging open. A peg is used to lock the arm in this position. Thus, the lock prevents the door from being opened unless the peg is removed and the bias moves the arm back to the retracted postion.
