Abstract
Abstract An integral piece for applying to a sharp corner element such as on a window frame, having a base with a recess in its under surface with flanges or ribs on two contiguous sides. Rising from the base is a rounded boss, symmetrical on a diagonal line from the juncture of the flanges. When applied to the window frame, the flanges fit against the edges of the frame forming the sharp corner, and the boss extends both up from the base and generally toward the corner. The symmetry of the guard enables it to fit either corner of the window frame, i.e., either right or left. The guard is held in place alternatively by an adhesive material, or mechanical means such as a screw.

Claim 1
Independent Claim
362 words
A corner guard for use on a window in a wall, in combination with that window, wherein, the window includes at least one sash having a surrounding frame, the sash is swingable between open and closed positions on an axis adjacent the wall the having a swingable edge spaced from the wall when in open position, and the sash when in closed position lies closely adjacent the plane of the wall with the swinging edge consequently also closely adjacent that plane, the sash having an inner surface and an outer surface relative to its closed position, the frame being of metal or similar hard material having sharp corners which readily cause injury to the body of a person having impact therewith, the corner guard being an integral article including a base and a boss rising therefrom, the base having a recess in an under side defined on one side by a main surface of the base, and on other sides by downwardly extending flanges on two contiguous sides of the base, the surfaces of the base that define the recess being flat and commonly intersecting and defining a sharp inside corner, the corner guard being fitted to the outer surface of frame with the main surface of the recess engaging the outer surface of the frame, and the flanges engaging the peripheral edges of the frame, the inner surface of the frame being clear of the corner guard and correspondingly unobstructed, whereby the sash can be moved to its closed position unimpeded by the corner guard and thereby capable of engaging any element in the window by the inner surface of the sash that it could engage without the corner guard fitted thereto, said boss extending laterally from the base beyond both of the flanges and the corner therebetween, and the boss and those portions of the flanges at the juncture thereof together extending the full dimension of the guard in direction perpendicular to said main surface, whereby the guard at said juncture is positioned for receiving impact from all directions except in direction against the inner surface, the material of the corner guard being softer than the metal of the frame.
