Abstract
Abstract A multiplanar device has at least one component that consists of two rigid plastic wall members that have major areas of substantially uniform thickness, strips of considerably greater thickness along the side portions of said wall members, and a miter joint between the two wall members. A continuous thin film of flexible plastic is bonded to the two wall members and around the outside of the miter joint. The method of making the component is to mold it as a flat intermediate piece with a V-notch between the strips of greater thickness and to simultaneously bond the film to the surface at the apex of the V; and to thereafter apply adhesive to the sides of the V and bend the piece to bring the sides of the notch together and bond them together. Several such components may be connected with other similar or dissimilar components at miter joints to form a complete multiplanar device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A component for a multiplanar device having effectively planar, angularly related, rigid molded plastic walls, said component comprising: first and second effectively planar polygonal wall members of substantially rigid molded plastic which have major areas of substantially uniform thickness, said wall members having strips along their adjacent side portions which are substantially thicker than said major areas and the adjacent sides of said wall members forming a miter joint which positions said wall members at a predetermined angle to one another, said adjacent sides being bonded together; and a thin film of flexible plastic bonded to substantially the entirely of said wall members and forming a connection between said wall members around the outside of the miter joint.
Claim 2
Dependent Claim
118 words
A component for a multiplanar device having effectively planar, angularly related, rigid molded plastic walls, said component comprising: first and second effectively planar polygonal wall members of substantially rigid molded plastic which have major areas of substantially uniform thickness, said wall members having strips along their adjacent side portions which are substantially thicker than said major areas and the adjacent sides of said wall members forming a miter joint which positions said wall members at a predetermined angle to one another, said adjacent sides being bonded together; and a thin film of flexible plastic bonded to substantially the entirely of said wall members and forming a connection between said wall members around the outside of the miter joint.
Claim 3
Dependent Claim
72 words
The component of claim 1 in which each of said first and second wall members has a strip along each side portion which is substantially thicker than said major areas, and each side is a miter constructed and arranged to permit a plurality of components, all having thickened strips along each side and with the sides being miters, to be bonded to one another along said miters to form said multiplanar device.
Claim 4
Dependent Claim
20 words
The component of claim 1 or claim 2 in which each thicker strip is defined by an inwardly projecting rib.
Claim 5
Dependent Claim
20 words
The component of claim 1 or claim 2 in which each thicker strip is defined by an outwardly projecting rib.
