Abstract
Abstract A folding article of furniture including parallel pairs of crossed first legs and second legs pivotably joined to each other, first and second arms pivotably joined, respectively, to the top ends of the first and second legs, a first top piece overlaying and joined to the distal portion of the first arms, a second top piece overlaying and joined to the distal portions of the second arms and a brace transversely joining the lower portion of the first legs. A back assembly, which converts the article to a chair, is pivotably joined to the distal ends of the first arms and includes a lower end portion which engages the brace and the first legs to limit pivoting of the back assembly. In some forms, a handle joins the proximal ends of corresponding arms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
299 words
A foldable article of furniture comprising in combination: (a) a plurality of crossed pairs of legs, each pair including a first leg and a second leg, each leg having a first pivot point adjacent the top end of each leg and a second pivot point intermediate its ends, each first leg being pivotably joined to a corresponding second leg at their respective second pivot points; (b) a plurality of first and second arms each having a third pivot point adjacent an end, each of said first arms being pivotably joined to a first leg between the third pivot point and the first pivot point, each of said second arms being pivotably joined to a second leg between the third pivot point and the first pivot point; (c) a first top panel extending normally and overlying and joined to each of said first arms distal to the third pivot points thereof and including an inner face at the end proximal the third pivot points of said first arms; (d) a second top panel overlying and joined to each of said second arms distal to the third pivot points thereof and including an inner face at the end proximal the third pivot points of said second arms; (e) a brace overlying and joined to said first legs extending normally to and adjacent to the bottom ends thereof distal said first pivot points; (f) said first arms being held in parallel relation by said first top panel, said second arms being held in parallel relation by said second panel and said first legs being held in parallel relation by said brace; and (g) a removable spacing insert removably received over the intermediate portions of said arms and clamped by and between the inner faces of said first panel and said second panel.
Claim 2
Dependent Claim
299 words
A foldable article of furniture comprising in combination: (a) a plurality of crossed pairs of legs, each pair including a first leg and a second leg, each leg having a first pivot point adjacent the top end of each leg and a second pivot point intermediate its ends, each first leg being pivotably joined to a corresponding second leg at their respective second pivot points; (b) a plurality of first and second arms each having a third pivot point adjacent an end, each of said first arms being pivotably joined to a first leg between the third pivot point and the first pivot point, each of said second arms being pivotably joined to a second leg between the third pivot point and the first pivot point; (c) a first top panel extending normally and overlying and joined to each of said first arms distal to the third pivot points thereof and including an inner face at the end proximal the third pivot points of said first arms; (d) a second top panel overlying and joined to each of said second arms distal to the third pivot points thereof and including an inner face at the end proximal the third pivot points of said second arms; (e) a brace overlying and joined to said first legs extending normally to and adjacent to the bottom ends thereof distal said first pivot points; (f) said first arms being held in parallel relation by said first top panel, said second arms being held in parallel relation by said second panel and said first legs being held in parallel relation by said brace; and (g) a removable spacing insert removably received over the intermediate portions of said arms and clamped by and between the inner faces of said first panel and said second panel.
Claim 3
Dependent Claim
125 words
A foldable article of furniture as claimed in claim 1 wherein each first leg is sidewise adjacent to a second leg, each first arm is sidewise adjacent a first leg on the side opposite the adjacent said second leg, and each second arm is adjacent a second leg on the side opposite the adjacent first leg; said arms, legs and top panels being dimensioned to permit a first configuration with said first top panel overlying the portion of said second arms proximal to the third pivot points thereof, said second top panel overlying the portion of said first arms proximal to the third pivot points thereof and the inner face of said first top piece abutting against the inner face of said second top piece.
Claim 4
Dependent Claim
136 words
A foldable article of furniture as claimed in claim 2 further comprising a back frame including two side members, a back support extending between said side members adjacent their top ends and a bottom bar extending between said side members adjacent their bottom ends, each side member having a fourth pivot point intermediate its ends; two of said first arms each having a fifth pivot point adjacent the end distal to said third pivot points, each of said fourth pivot points being pivotably joined to one of said fifth pivot points; said side members having sufficient length between said fifth pivot points and said bottom bar for said bottom bar to engage said first legs and said brace to limit rotation about said fourth pivot points when said article of furniture is in said first configuration.
Claim 5
Dependent Claim
30 words
A foldable article of furniture as claimed in claim 3 wherein said back frame further including means adjacent said back support for removably receiving and holding said removable spacing insert.
Claim 6
Dependent Claim
76 words
A foldable article of furniture as claimed in claim 2 further comprising a removable spacing insert fitted over the intermediate portions of said arms and having one side abutting the inner face of said first top panel and the opposite side abutting the inner face of said second top panel for forming a second configuration with a top surface higher and wider than that formed by said first and second top panels in said first configuration.
Claim 7
Dependent Claim
30 words
A foldable article of furniture as claimed in claim 2 further comprising a second brace overlying and attached to said second legs and holding said second legs in parallel relationship.
Claim 8
Dependent Claim
132 words
A foldable piece of furniture as claimed in claim 2 including two of said first legs, two of said second legs, two of said first arms, two of said second arms; and said arms, legs and first and second top pieces are dimensioned such that, in said first configuration, said top ends of said first legs, said proximal ends of said first arms, said distal ends of said second arms and the face of said first top piece opposite the inner face thereof are all in substantial alignment and, in said first configuration, the top ends of said second legs, the proximal ends of said second arms, the distal ends of said first arms and the face of said second top piece opposite the inner face thereof are all in substantial alignment.
