Abstract
Abstract A unitary protective wall member guard such as for a corner consisting of an underlying layer conforming to the wall member and a second overlying layer spaced from said first layer there across for a substantial extent thereof and said layers having common side edge portions, said second layer being in spaced relation to said wall member, being yieldingly resistant to impact, saving the underlying corner member from the direct effect of the impact and distributing the impact throughout the extent of itself.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A unitarily formed wall member guard structure, comprising a separated body portion formed of resilient deformable material, said body portion having an underlying and an overlying layer, said layers having common side edge portions at either side of said body portion, said overlying layer diverging from the underlying layer at an acute angle from each of said common side edge portions defining a space therebetween of increasing separation, said underlying layer having a smooth unbroken underlying surface conforming to an underlying wall surface, and said overlying layer deformably yielding under impact to insulate said underlying layer and underlying wall surface from the effect of said impact,
Claim 2
Dependent Claim
106 words
A unitarily formed wall member guard structure, comprising a separated body portion formed of resilient deformable material, said body portion having an underlying and an overlying layer, said layers having common side edge portions at either side of said body portion, said overlying layer diverging from the underlying layer at an acute angle from each of said common side edge portions defining a space therebetween of increasing separation, said underlying layer having a smooth unbroken underlying surface conforming to an underlying wall surface, and said overlying layer deformably yielding under impact to insulate said underlying layer and underlying wall surface from the effect of said impact,
Claim 3
Dependent Claim
16 words
The structure set forth in claim 1, wherein said underlying layer has a underlying adhesive surface.
Claim 4
Dependent Claim
20 words
The structure set forth in claim 1, including means securing said common edge portions to an underlying wall surface portion.
Claim 5
Dependent Claim
28 words
The structure set forth in claim 1, wherein said underlying and said overlying layers having spaced overlapping integral portions centrally thereof remote from said common side edge portions.
