Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A freestanding, movable space divider comprising a frame and a panel supported in said frame, said frame including at least one frame member, said frame member being elongated, said elongated frame member having along its length a pair of substantially parallel panel embracing arms, said arms extending over the opposite faces of said panel in engagement therewith, said panel being resilient in a direction transverse to the major faces thereof whereby said panel may be slightly compressed between said embracing arms and will recover substantially its original thickness to firmly engage said arms, said panel including two outer laminae and at least one internal lamina, said two outer laminae being of acoustical insulation board having acoustical openings therein extending from the outer surfaces thereof, and said internal lamina being a resilient sheet.
Claim 2
Dependent Claim
132 words
A freestanding, movable space divider comprising a frame and a panel supported in said frame, said frame including at least one frame member, said frame member being elongated, said elongated frame member having along its length a pair of substantially parallel panel embracing arms, said arms extending over the opposite faces of said panel in engagement therewith, said panel being resilient in a direction transverse to the major faces thereof whereby said panel may be slightly compressed between said embracing arms and will recover substantially its original thickness to firmly engage said arms, said panel including two outer laminae and at least one internal lamina, said two outer laminae being of acoustical insulation board having acoustical openings therein extending from the outer surfaces thereof, and said internal lamina being a resilient sheet.
Claim 3
Dependent Claim
19 words
The space divider of claim 1 in which said panel includes a resilient foam material to provide the resiliency.
Claim 4
Dependent Claim
19 words
The space divider of claim 1 in which said panel includes a nonwoven fibrous mat to provide the resiliency.
Claim 5
Dependent Claim
21 words
The space divider of claim 1 in which at least one of said outer laminae includes an outer finish covering sheet.
Claim 6
Dependent Claim
18 words
The space divider of claim 4 in which both of said outer laminae include outer finish covering sheets.
Claim 7
Dependent Claim
154 words
A freestanding, movable space divider comprising a frame and a panel supported in said frame, said frame including at least one frame member, said frame member being elongated, said elongated frame member having along its length a pair of substantially parallel panel embracing arms, said arms extending over the opposite faces of said panel in engagement therewith, said panel including at least three laminae, the two outer laminae being relatively incompressible with respect to the inner lamina in a direction perpendicular to the major faces of said panel, said inner lamina being easily highly compressible relative to said outer laminae in a direction perpendicular to the major faces of said panel, and said inner lamina being able to readily recover substantially its original thickness, whereby said panel may be readily compressed to a thickness less than the distance between said embracing arms and will recover substantially its original thickness to firmly engage said arms.
Claim 8
Dependent Claim
154 words
A freestanding, movable space divider comprising a frame and a panel supported in said frame, said frame including at least one frame member, said frame member being elongated, said elongated frame member having along its length a pair of substantially parallel panel embracing arms, said arms extending over the opposite faces of said panel in engagement therewith, said panel including at least three laminae, the two outer laminae being relatively incompressible with respect to the inner lamina in a direction perpendicular to the major faces of said panel, said inner lamina being easily highly compressible relative to said outer laminae in a direction perpendicular to the major faces of said panel, and said inner lamina being able to readily recover substantially its original thickness, whereby said panel may be readily compressed to a thickness less than the distance between said embracing arms and will recover substantially its original thickness to firmly engage said arms.
Claim 9
Dependent Claim
15 words
The space divider of claim 6 in which said inner lamina is a resilient foam.
Claim 10
Dependent Claim
17 words
The space divider of claim 6 in which said inner lamina is a flexible bonded fibrous mat.
Claim 11
Dependent Claim
21 words
The space divider of claim 6 in which at least one of said outer laminae includes an outer finish covering sheet.
Claim 12
Dependent Claim
18 words
The space divider of claim 9 in which both of said outer laminae include outer finish covering sheets.
