Abstract
Abstract A chair base includes a vertical column from which radiate a plurality of legs each having a top plate and a caster-receiving socket adjacent its distal portion. An end cap is removably mounted about the socket while a separate integral scuff cap is slidably attached in an overlying manner to each leg and extends in an upward direction to overlie a portion of the base column.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
A chair base including, a central chair supporting column, a plurality of legs rigidly affixed to and radiating from said column, separate cover means overlying each of said legs and individually mountable thereon, each said cover means comprising a unitary cover member including longitudinally projecting section, a vertically extending section and an intermediate upwardly curved section, said longitudinally projecting section extending inwardly from the distal portion of each leg to said curved section juxtaposed the juncture of said leg and column, said vertically extending section overlying and biased against the periphery of said column above the plane of said legs, and each said cover means including integral locking means comprising flanges along the lower portion of said longitudinally projecting section engageable with said leg as said cover means is slidably attached thereto and fully overlies the upper portion of said respective leg.
Claim 2
Dependent Claim
142 words
A chair base including, a central chair supporting column, a plurality of legs rigidly affixed to and radiating from said column, separate cover means overlying each of said legs and individually mountable thereon, each said cover means comprising a unitary cover member including longitudinally projecting section, a vertically extending section and an intermediate upwardly curved section, said longitudinally projecting section extending inwardly from the distal portion of each leg to said curved section juxtaposed the juncture of said leg and column, said vertically extending section overlying and biased against the periphery of said column above the plane of said legs, and each said cover means including integral locking means comprising flanges along the lower portion of said longitudinally projecting section engageable with said leg as said cover means is slidably attached thereto and fully overlies the upper portion of said respective leg.
Claim 3
Dependent Claim
47 words
A chair base according to claim 1 wherein, said cover means includes a top portion adapted to overlie said leg and a portion of said column, a side wall depending from each lateral edge of said top portion, and said flanges project inwardly from said side walls.
Claim 4
Dependent Claim
32 words
A chair base according to claim 1 wherein, each said leg includes a vertical web attached to the undersurface of a horizontal plate and said cover means overlies and engages said plate.
Claim 5
Dependent Claim
49 words
A chair base according to claim 1 wherein, each said leg includes a horizontal plate having a straight portion adjacent the distal end of the leg provided with substantially parallel lateral edges, and said locking flanges on said cover member longitudinal section are engageable beneath said plate lateral edges.
Claim 6
Dependent Claim
39 words
A chair base according to claim 3 including, a caster-receiving socket element adjacent the end of the undersurface of said horizontal plate, a toe cap having a central bore slidably mounted about said socket element beneath said cover means.
Claim 7
Dependent Claim
