Window safety barrier

A removable window safety barrier comprises:

• two vertical frame members, one at the first end of said barrier and the other at a second end of said barrier, joined together by two horizontal frame members at third and fourth ends of said barrier, said barrier including two or more additional horizontal members between said horizontal frame members to prevent passage through the frame by a person, and at least one additional vertical member attached to each of said horizontal members in said barrier, said barrier including, at each end of said vertical frame members, a flange having a hole of suitable size and shape to engage and be supported by pins affixed to the sides of a window, with two of said pins positioned near and pointing upwardly from the bottom of said window, and two other pins pointing downwardly toward said sill, said upwardly pointing and said downwardly pointing pins being spaced sufficiently far apart so that said barrier can be placed with its flanges at one end of said vertical members on the downwardly pointing pins and the holes in the other end of said vertical members seated on the pins projecting upwardly from said window sill.
