Abstract

Abstract A chair is formed from a single blank of paper stock material coated with a decorative and detergent-resistant coating. The blank comprises panels separated by score lines. The panels, when folded along the score lines, form sides and each side comprises spaced outer and inner panels interlocked by cooperating slots and tabs, the tabs also serving as arm rests. The blank further provides end panels which overlay the panel forming the back of the assembled chair. A seat panel is secured to the top of the back panel by another panel which folds over the back panel and brings the seat panel to its proper position between the inner side panels. The seat panel is secured to the inner side panels by slots and tabs. A rail member extends between the inner side panels and further supports the seat. The coatings can be applied to any paper furniture. The coating is formed of elastic, marresistant paint layers which are based upon elastic polyester, elastic polyester polyurethane, elastic epoxy ester and elastic silicone resins for the intermediate and top layers. These resin materials have outstanding color retention and weather resistance and can be rubber or polished to a glossy finish to match the best grades of lacquers which are commercially available.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 36 words
The blank for forming a chair as defined in claim 1 wherein each end panel has an oppositely extending slit which interengages to lock said end panels in the position wherein they overlay the back panel.
Claim 2
Dependent Claim 50 words
The blank for forming a chair as defined in claim 2 wherein the interlocking means securing the inner and outer side panels comprise mutually interlocking tab and slot means, and wherein the means for securing the seat panel to the inner side panels comprise mutually interlocking tab and slot means.
Claim 3
Dependent Claim 37 words
The blank for forming a chair as defined in claim 3 wherein a rail means is provided to support the front of the seat panel, said rail means extending into slots formed in the inner side panels.
Claim 4
Dependent Claim 52 words
The blank for forming a chair as claimed in claim 4 wherein the spacing between each inner and outer side panel is maintained by the tab and slot means securing the seat panel to the inner side panels and by the ends of the rail means extending through their cooperating slot means.
Claim 5
Dependent Claim 33 words
The blank for forming a chair as defined in claim 3 wherein the first claimed tab and slot means bridge the spacing between the inner and outer side panels to form arm rests.
Claim 6
Dependent Claim 122 words
The blank for forming a chair as defined in claim 1 wherein the blank is coated with a decorative elastic and detergent-resistant coating which comprises a plurality of layers consisting of a primer coating and an elastic layer over the primer coating, the primer coating being in a thickness of up to about 1 mil and the elastic layer being at least 4 mils thick, and wherein said elastic layer if formed of a resin which provides a hard, mar-resistant, burn-resistant and stain-resistant surface and is selected from the group consisting of elastic polyester, elastic polyester polyurethane, elastic polyether polyurethane, elastic polyester amide polyurethane, elastic epoxy ester modified with aminoplast resin and alkyd resin, and elastic epoxy ester modified with acrylic resin.
Claim 7
Dependent Claim 58 words
A blank as defined in claim 7 wherein the elastic layer above the primer coating is composed of an intermediate layer and a top layer, the intermediate layer being more flexible than the top layer and containing a thickening agent, and wherein the top layer provides a hard, unpigmented surface which can be rubbed to a high gloss.
