Abstract
Abstract A pedestal base is assembled from a central post and radially extending legs, each leg having a hub portion including a hub segment, a hub sector and a groove segment between the hub segment and the hub sector such that upon abutment of the hub portions into a full cylindrical hub configuration, the central post is inserted into the groove established by the groove segments and locked in place to secure the hub portions in the full cylindrical hub configuration and the central post within the full cylindrical hub configuration without further supplemental fastener elements.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
215 words
In a readily assembled base for a pedestal having a central post and a plurality of legs radiating from the post to establish a basal support, the improvement wherein: the central post includes an axially extending tubular wall having a lowermost basal end with a given diameter and wall thickness; and each leg includes a radially extending support portion and an axially extending hub portion, the hub portion having a radially outer, axially extending hub segment, a radially inner axially extending hub sector, and an annular groove segment located radially between the hub segment and the hub sector and having a nominal radial width essentially complementary to, the wall thickness of the tubular wall of the central post adjacent the basal end thereof, the circumferential extent of the hub segment, the hub sector and the groove segment being such that upon assembly of the plurality of legs, the hub portions of the legs are abutted to establish a full cylindrical hub configuration having a fully annular groove for the reception of the basal end of the tubular wall of the central post, and upon insertion of the basal end of the tubular wall of the central post into the fully annular groove, the hub portions will be held assembled in the full cylindrical hub configuration.
Claim 2
Dependent Claim

In a readily assembled base for a pedestal having a central post and a plurality of legs radiating from the post to establish a basal support, the improvement wherein: the central post includes an axially extending tubular wall having a lowermost basal end with a given diameter and wall thickness; and each leg includes a radially extending support portion and an axially extending hub portion, the hub portion having a radially outer, axially extending hub segment, a radially inner axially extending hub sector, and an annular groove segment located radially between the hub segment and the hub sector and having a nominal radial width essentially complementary to, the wall thickness of the tubular wall of the central post adjacent the basal end thereof, the circumferential extent of the hub segment, the hub sector and the groove segment being such that upon assembly of the plurality of legs, the hub portions of the legs are abutted to establish a full cylindrical hub configuration having a fully annular groove for the reception of the basal end of the tubular wall of the central post, and upon insertion of the basal end of the tubular wall of the central post into the fully annular groove, the hub portions will be held assembled in the full cylindrical hub configuration.
Claim 3
Dependent Claim
102 words
The improvement of claim 1 wherein the annular groove extends axially downwardly into the full cylindrical hub configuration from an open mouth for the reception of the basal end of the tubular wall and is tapered from a radial width at the open mouth slightly larger than the wall thickness of the basal end of the tubular wall to a radial width slightly smaller than the wall thickness of the basal end of the tubular wall such that upon insertion of the basal end of the tubular wall into the annular groove, the tubular wall will be wedged within the annular groove.
Claim 4
Dependent Claim
86 words
The improvement of claim 2 wherein the annular groove has a wedge-shaped cross-sectional configuration including an outer peripheral surface on the hub sectors tapered radially inwardly in the axial direction from the smaller radial width toward the larger radial width, such that upon insertion of the basal end of the tubular wall into the annular groove, the tubular wall will engage the outer peripheral surface and urge the hub portions radially inwardly to maintain and hold the hub portions tightly within the full cylindrical hub configuration.
Claim 5
Dependent Claim
34 words
The improvement of claim 1 wherein the hub sector of the leg has a given axial extent and the hub segment of that leg extends axially beyond the axial extent of the hub sector.
Claim 6
Dependent Claim
18 words
The improvement of claim 1 wherein the leg is a unitary structure molded of a synthetic resin material.
Claim 7
Dependent Claim
59 words
The improvement of claim 1 including an annular ring for reception radially over the assembled hub segments in the full cylindrical hub configuration, the relative dimensions of the annular ring and the hub segments being such that the annular ring will grip the hub segments to assist in maintaining the hub segments assembled in the full cylindrical hub configuration.
Claim 8
Dependent Claim
59 words
The improvement of claim 6 wherein the hub segment includes an uppermost end and the ring comprises an annular collar having an axial sleeve portion for circumferentially surrounding the hub segments of the fully assembled hub configuration and a radial flange portion for seating upon the axially uppermost ends of the hub segments in the fully assembled hub configuration.
Claim 9
Dependent Claim
100 words
The improvement of claim 7 wherein the annular groove extends axially downwardly into the hub configuration from an open mouth for the reception of the basal end of the tubular wall and is tapered from a radial width at the open mouth slightly larger than the wall thickness of the basal end of the tubular wall to a radial width slightly smaller than the wall thickness of the basal end of the tubular wall such that upon insertion of the basal end of the tubular wall into the annular groove, the tubular wall will be wedged within the annular groove.
Claim 10
Dependent Claim
86 words
The improvement of claim 8 wherein the annular groove has a wedge-shaped cross-sectional configuration including an outer peripheral surface on the hub sectors tapered radially inwardly in the axial direction from the smaller radial width toward the larger radial width, such that upon insertion of the basal end of the tubular wall into the annular groove, the tubular wall will engage the outer peripheral surface and urge the hub portions radially inwardly to maintain and hold the hub portions tightly within the full cylindrical hub configuration.
Claim 11
Dependent Claim
34 words
The improvement of claim 7 wherein the hub sector of the leg has a given axial extent and the hub segment of that leg extends axially beyond the axial extent of the hub sector.
Claim 12
Dependent Claim
18 words
The improvement of claim 7 wherein the leg is a unitary structure molded of a synthetic resin material.
