Abstract
Abstract This invention relates to a freestanding acoustical space divider in which an acoustically absorptive panel is supported around its periphery by a metal frame assembled without the use of the usual fasteners such as screws or bolts and in which adjacent sections are flexibly connected by means of a plastic hingelike coupling strip. The coupling strip has enlargements along each of its longitudinal edges which fit into appropriately shaped grooves in the frame of the sections.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A freestanding, readily movable space divider comprising a frame and a panel supported in said frame, said frame including a plurality of frame members, each of said frame members being elongated, each of said elongated frame members having along their length a pair of substantially parallel panel-embracing arms, and said arms extending over the opposite faces of said panel, said frame members being positioned end-to-end to surround the periphery of said panel, said panel being free of any attachment to said frame other than being embraced at its periphery by said arms of said frame members, at least one of said frame members having an outwardly opening groove along its length in each of two oppositely directed faces thereof, the openings of said grooves being narrower than the respective interior portions thereof, and at least one leg, said leg having oppositely inwardly directed flanges engaging said grooves to support said frame member.
Claim 2
Dependent Claim
152 words
A freestanding, readily movable space divider comprising a frame and a panel supported in said frame, said frame including a plurality of frame members, each of said frame members being elongated, each of said elongated frame members having along their length a pair of substantially parallel panel-embracing arms, and said arms extending over the opposite faces of said panel, said frame members being positioned end-to-end to surround the periphery of said panel, said panel being free of any attachment to said frame other than being embraced at its periphery by said arms of said frame members, at least one of said frame members having an outwardly opening groove along its length in each of two oppositely directed faces thereof, the openings of said grooves being narrower than the respective interior portions thereof, and at least one leg, said leg having oppositely inwardly directed flanges engaging said grooves to support said frame member.
Claim 3
Dependent Claim
127 words
A freestanding, readily movable space divider comprising a panel, a plurality of elongated frame members, means joining said frame members to each other at their ends to form a panel-supporting frame about the periphery of said panel, said joining means including an internal channel at least adjacent ends of said frame members and a key having legs extending into internal channels of two adjacent frame members to join said frame members together, said legs of said key being frictionally engaged in their respective channels, at least one of said frame members having an outwardly opening groove along its length in each of two oppositely directed faces thereof, and at least one leg, said leg having oppositely inwardly directed flanges engaging said grooves to support said frame member.
Claim 4
Dependent Claim
