Abstract
Abstract An antiglare panel is formed of a series of identical inter-locked strips. Each of the strips is formed of a series of "W" shapes having two connected short legs formed at right angles to each other and two long legs extending at right angles from a respective short leg to define the "W" shape. The long legs of adjacent "W's" are formed at right angles to define a projecting right angle. The projecting right angles of one strip are positioned within the recessed right angles of an adjacent strip so that the interior surface of the short legs overlie a portion of the exterior surface of the long legs to provide contacting surfaces. Such contacting surfaces may be secured together. In a preferred embodiment, the strips are formed of tinned steel strip, and the assembled strips are heated after assembly to a temperature above the melting point of the tin coating to provide a metal bond at all contacting surfaces.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
A cellular antiglare panel comprising a plurality of identical interlocked strips, each strip being formed of a series of "W" shapes having two connected short legs formed at right angles to each other defining a recessed right angle and two long legs each extending at right angles from a respective short leg to define the "W" shapes, the long legs of adjacent "W" shapes being formed at right angles with each other to define a projecting right angle, the exterior surface of the projecting right angles of one strip being positioned within and against the interior surface of the recessed right angles of an adjacent strip, so that the short legs of said adjacent strip overlie the long legs of said one strip to provide contacting surfaces.
Claim 2
Dependent Claim
127 words
A cellular antiglare panel comprising a plurality of identical interlocked strips, each strip being formed of a series of "W" shapes having two connected short legs formed at right angles to each other defining a recessed right angle and two long legs each extending at right angles from a respective short leg to define the "W" shapes, the long legs of adjacent "W" shapes being formed at right angles with each other to define a projecting right angle, the exterior surface of the projecting right angles of one strip being positioned within and against the interior surface of the recessed right angles of an adjacent strip, so that the short legs of said adjacent strip overlie the long legs of said one strip to provide contacting surfaces.
Claim 3
Dependent Claim
18 words
A cellular antiglare panel as set forth in claim 1 and including means securing said contracting surfaces together.
Claim 4
Dependent Claim
45 words
A cellular antiglare panel as set forth in claim 1 wherein said strips are formed of tinned steel strip which have been heated after assembly to a temperature above the melting point of the tin coating to provide a metal bond at all contacting surfaces.
Claim 5
Dependent Claim
66 words
A cellular antiglare panel as set forth in claim 1 wherein said "W" shapes are formed along one longitudinal half of each strip, and a series of "M" shapes are formed along the other longitudinal half of each strip, and wherein both said "M" shapes and said "W" shapes are formed of said short and long legs defining alternates recessed right angles and projecting right angles.
Claim 6
Dependent Claim
149 words
A cellular antiglare panel conprising a plurality of interlocked strips, each strip being formed with a series of "W" shapes along one longitudinal half of said strip and a series of "M" shapes along the other longitudinal half of said strip; each of said "M" and "W" shapes having two connected short legs formed at right angles to each other and two long legs each extending at right angles from a respective short leg to define the "M" shapes, the long legs of adjacent "W" shapes being formed at right angles with each other to define a projecting right angle, the exterior surface of the projecting right angles of one strip being positioned within and against the interior surface of the recessed right angles of an adjacent strip, so that the short legs of said adjacent strip overlie the long legs of said one strip to provide contacting surfaces.
Claim 7
Dependent Claim
149 words
A cellular antiglare panel conprising a plurality of interlocked strips, each strip being formed with a series of "W" shapes along one longitudinal half of said strip and a series of "M" shapes along the other longitudinal half of said strip; each of said "M" and "W" shapes having two connected short legs formed at right angles to each other and two long legs each extending at right angles from a respective short leg to define the "M" shapes, the long legs of adjacent "W" shapes being formed at right angles with each other to define a projecting right angle, the exterior surface of the projecting right angles of one strip being positioned within and against the interior surface of the recessed right angles of an adjacent strip, so that the short legs of said adjacent strip overlie the long legs of said one strip to provide contacting surfaces.
