Abstract
Abstract A super stable, simply assembleable tree stand is provided for artificial Christmas trees and the like, which stand provides increased stability in relation to the load applied. The stand includes a central, disc-shaped hub portion which interlocks vertically and horizontally with a plurality of radiating, tapered legs, with the component parts so configured that, when interlocked, they cannot be separated under load, or loosen or "wobble" with respect to each other. The component parts are comprised of substantially rigid thermoplastic resin material with a slight degree of resiliency, such as high impact polystyrene, so as to provide a gripping action between the parts when they are joined. The legs are connected to the hub portion with a tongue and groove arrangement connectable from the bottom of the stand upwardly, so that applied loads from above serve to urge the tongue and groove joints into a fully seated and totally stable condition.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
A tree stand assembly comprising (a) a one-piece molded central hub means including 1. a central tubular socket means having a generally horizontal bottom; 2. a conical skirt means extending outwardly and downwardly from the uppermost portions of said socket means; 3. vertically extending leg coupling means integrally formed on the outer surfaces of said socket means; 4. locking pin means integrally formed at peripheral edges of the underside of said skirt means and aligned radially with each of said leg coupling means; and (b) a plurality of one-piece molded horizontally extending leg means
Claim 2
Dependent Claim
94 words
A tree stand assembly comprising (a) a one-piece molded central hub means including 1. a central tubular socket means having a generally horizontal bottom; 2. a conical skirt means extending outwardly and downwardly from the uppermost portions of said socket means; 3. vertically extending leg coupling means integrally formed on the outer surfaces of said socket means; 4. locking pin means integrally formed at peripheral edges of the underside of said skirt means and aligned radially with each of said leg coupling means; and (b) a plurality of one-piece molded horizontally extending leg means
Claim 3
Dependent Claim
125 words
each of said leg means including pad means at the distal ends thereof and including vertically extending feet means at the inner ends thereof; 2. hub coupling means formed integrally on the uppermost inner edges of said leg means and adapted to be firmly matable with said aforementioned leg coupling means; 3. the uppermost edges of said leg means being adapted to be engaged with said locking pin means when said coupling means are fully engaged in a manner whereby said leg means and said central hub means may be readily and quickly assembled into a rigid and stable artificial tree supporting unit; 4. said vertically extending feet means having horizontal surfaces adapted to engage with and support the bottom of said tubular socket means.
Claim 4
Dependent Claim
125 words
each of said leg means including pad means at the distal ends thereof and including vertically extending feet means at the inner ends thereof; 2. hub coupling means formed integrally on the uppermost inner edges of said leg means and adapted to be firmly matable with said aforementioned leg coupling means; 3. the uppermost edges of said leg means being adapted to be engaged with said locking pin means when said coupling means are fully engaged in a manner whereby said leg means and said central hub means may be readily and quickly assembled into a rigid and stable artificial tree supporting unit; 4. said vertically extending feet means having horizontal surfaces adapted to engage with and support the bottom of said tubular socket means.
Claim 5
Dependent Claim
37 words
The tree stand assembly of claim 1, in which said leg coupling means and said hub coupling means are in the form of tongue and groove connectors integrally formed on said hub means and said leg means.
Claim 6
Dependent Claim
27 words
The tree stand assembly of claim 1, in which said socket means are provided with integral internal tapered rib means adapted to engage an artificial tree trunk.
Claim 7
Dependent Claim
157 words
In a tree stand of molded resin material, comprising (a) a body; (b) a vertically extending, tree trunk receiving aperture formed in the center of said body and having a generally horizontal bottom; (c) a plurality of supporting legs extending substantially horizontally from said body; the improvement characterized by (d) cooperating tongue-in-groove connections between said body and each of said legs; (e) an integral conical skirt on the upper periphery of said body, said skirt depending downwardly and outwardly from said aperture; (f) the outer circumferential edge of said skirt engaging the top surface of each said leg; and (g) an integral ground engaging abutment on each said leg at the end thereof adjacent said body and having a horizontal upper surface; (h) the bottom surface of each said abutment spaced above the supporting surface of said stand when said stand is not under load; (i) said upper surface of each said abutment engaging said horizontal bottom.
Claim 8
Dependent Claim
157 words
In a tree stand of molded resin material, comprising (a) a body; (b) a vertically extending, tree trunk receiving aperture formed in the center of said body and having a generally horizontal bottom; (c) a plurality of supporting legs extending substantially horizontally from said body; the improvement characterized by (d) cooperating tongue-in-groove connections between said body and each of said legs; (e) an integral conical skirt on the upper periphery of said body, said skirt depending downwardly and outwardly from said aperture; (f) the outer circumferential edge of said skirt engaging the top surface of each said leg; and (g) an integral ground engaging abutment on each said leg at the end thereof adjacent said body and having a horizontal upper surface; (h) the bottom surface of each said abutment spaced above the supporting surface of said stand when said stand is not under load; (i) said upper surface of each said abutment engaging said horizontal bottom.
Claim 9
Dependent Claim

The stand of claim 4, with each said leg further characterized by (a) a web portion with an upper surface inclined downwardly from adjacent said body to the outer end thereof; (b) an upper flange integral with said upper surface; and (c) said outer surface of said skirt engaging said upper flange.
Claim 11
Dependent Claim
27 words
The stand of claim 4, further characterized by (a) the engaging surfaces of said cooperating tongue-in-groove connections being vertical and engagable from the bottom of said stand.
Claim 12
Dependent Claim
