Abstract
Abstract An improved sound absorptive tackable space dividing wall panel or similar article in which a wire mesh screen is disposed within the sound absorptive material a distance from the tackable surface less than the length of the tack pin, thereby providing additional support for the tackable load without appreciably reducing the sound absorptive characteristics of the panel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
133 words
A sound absorptive tackable space dividing wall panel for receiving tacks and the like comprising: a frame; a rigid central support member dividing said wall panel into two sides and bounded by said frame; first sound absorptive layers on each side of said central support member; a wire mesh screen covering the outer surface of each of said first sound absorptive layers; a second sound absorptive layer covering the outer surface of each of said wire mesh screens; and a cover cloth covering each of said second sound absorptive layers and forming the surfaces of said sound absorptive tackable wall panel, the combined thickness of said second sound absorptive layer and adjacent cover cloth being less than the length of the pin portions of said tacks and the like intended for use therewith.
Claim 2
Dependent Claim
133 words
A sound absorptive tackable space dividing wall panel for receiving tacks and the like comprising: a frame; a rigid central support member dividing said wall panel into two sides and bounded by said frame; first sound absorptive layers on each side of said central support member; a wire mesh screen covering the outer surface of each of said first sound absorptive layers; a second sound absorptive layer covering the outer surface of each of said wire mesh screens; and a cover cloth covering each of said second sound absorptive layers and forming the surfaces of said sound absorptive tackable wall panel, the combined thickness of said second sound absorptive layer and adjacent cover cloth being less than the length of the pin portions of said tacks and the like intended for use therewith.
