ABSTRACT:
A shutter-type window gate device has a hinged shutter panel defining a vertical guide at its unhinged side for guiding a vertical slidable bolt. The vertical slidable bolt is adapted to engage latch elements on the frame of the device in a locked upper position of the bolt. The vertical slidable bolt has a horizontal latching projection to adapted to engage the top of a horizontal resiliently biased bolt, in the locked upper position of the slidable bolt, thereby holding the vertical slidable bolt in its locked position. In the lower, unlocked, position of the vertical slidable bolt, its latching projection is aligned with the resiliently horizontally biased bolt, to enable free vertical movement of the slidable bolt by an operator.
