Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An article of manufacture convertible into a number of reclining and sitting positions, comprising: a plurality of parallel resilient cushioning bolster elements defining an occupant supporting area; a corresponding plurality of spindles, each of which extends longitudinally through a respective bolster element and wherein the end of each spindle defines a pair of adjacent annular grooves for respectively receiving adjacent links, and a plurality of links apertured to fit over the spindle ends with overlapping ends extending between the ends of adjacent spindles and rotatably joining the spindles and bolster elements to each other in any one of a number of selectable relative positions for reclining and sitting, the links being constructed and arranged to interconnect the ends of the spindles such that the resilient bolsters are compressed against each other whereby they exert force tending to maintain the elements in assembly.
Claim 2
Dependent Claim
142 words
An article of manufacture convertible into a number of reclining and sitting positions, comprising: a plurality of parallel resilient cushioning bolster elements defining an occupant supporting area; a corresponding plurality of spindles, each of which extends longitudinally through a respective bolster element and wherein the end of each spindle defines a pair of adjacent annular grooves for respectively receiving adjacent links, and a plurality of links apertured to fit over the spindle ends with overlapping ends extending between the ends of adjacent spindles and rotatably joining the spindles and bolster elements to each other in any one of a number of selectable relative positions for reclining and sitting, the links being constructed and arranged to interconnect the ends of the spindles such that the resilient bolsters are compressed against each other whereby they exert force tending to maintain the elements in assembly.
Claim 3
Dependent Claim
14 words
The article of claim 1 wherein each bolster element defines a longitudinal spindle-receiving passage.
Claim 4
Dependent Claim
162 words
An article of manufacture convertible into a number of reclining and sitting positions, comprising: a plurality of parallel resilient cushioning bolster elements defining an occupant supporting area; a corresponding plurality of spindles, each of which extends longitudinally through a respective bolster element, the end of each spindle defining a pair of adjacent annular grooves for respectively receiving adjacent links, the links being apertured to fit over the spindle ends, and a plurality of links with overlapping ends extending between the ends of adjacent spindles and rotatably joining the spindles and bolster elements to each other in any one of a number of selectable relative positions for reclining and sitting, the links defining a pair of spaced apertures for respectively fitting over the ends of adjacent spindles, the apertures being spaced such that adjacent spindles are drawn together to squeeze the bolster elements together whereby their resiliency exerts a force tending to push the spindles apart thus securing the links in the grooves.
Claim 5
Dependent Claim
162 words
An article of manufacture convertible into a number of reclining and sitting positions, comprising: a plurality of parallel resilient cushioning bolster elements defining an occupant supporting area; a corresponding plurality of spindles, each of which extends longitudinally through a respective bolster element, the end of each spindle defining a pair of adjacent annular grooves for respectively receiving adjacent links, the links being apertured to fit over the spindle ends, and a plurality of links with overlapping ends extending between the ends of adjacent spindles and rotatably joining the spindles and bolster elements to each other in any one of a number of selectable relative positions for reclining and sitting, the links defining a pair of spaced apertures for respectively fitting over the ends of adjacent spindles, the apertures being spaced such that adjacent spindles are drawn together to squeeze the bolster elements together whereby their resiliency exerts a force tending to push the spindles apart thus securing the links in the grooves.
Claim 6
Dependent Claim
11 words
The article of claim 3 wherein the bolster elements are cylindrical.
Claim 7
Dependent Claim
16 words
The article of claim 3 wherein the apertures are holes contained wholly within the link body.
Claim 8
Dependent Claim
15 words
The article of claim 5 wherein the holes are circular as are the spindle grooves.
