ABSTRACT:
An escapable guard system includes means for securance of a grill having at each side thereof to be attached to a window frame or the like a channel with legs outturned; for co-acting with channels of this type a self-protective fastening system is provided which on unlocking provides instant full access to the window opening; the fastening system includes for one side of such a grill an angled guard latch which fits within a channel where it is secured by carriage bolts passing through respective square holes in the channel and into square holes in base members of this invention which the square under-portion of each rounded head of the carriage bolt type machine screw fits, leaving exposed only the featureless semi-spherical portion of the bolt head; this guard latch co-acts with a frame latch which covers the nuts on the carriage bolts when attached to a window frame and which can be locked to the guard latch by a padlock; for the other side of such a grill similarly secured hinge hooks are provided which have angled portions for detachably securing through openings in respective hinge catch plates in such manner that it is only necessary to unlock the grill to remove it entirely, if desired.
