Abstract
Abstract A stand or stool includes a top providing an upwardly facing supporting surface and a downwardly facing surface including a plurality of locking channels. The stand or stool includes a plurality of legs, each leg having a top portion for engagement in a respective locking channel on the downwardly facing surface of the top, and a foot portion for resting on a floor or article of furniture. The legs are readily disengageable from the top by sliding the leg top portions from the locking channels, making the stand collapsible. The stand includes a brace which is generally ring-like and sized to slide downwardly over the top and legs. A locking protrusion is provided on the outer edge of each leg for engaging a respective pocket provided on the brace to lock the legs in spaced-apart relation to one another. In the illustrated embodiment, the locking channels extend generally radially from the center of the top. Each leg includes an inner edge which is provided with a stacking support. The stacking supports permit vertical stacking of stands, each stand in a vertical stack receiving the top of the next subjacent stand in the stack in nested orientation.

A supporting stand comprising a top providing an upwardly facing supporting surface and a downwardly facing surface providing a plurality of channels, and a plurality of legs, each leg having a top portion for engagement with a respective channel on the downwardly facing surface, the legs being readily disengageable from the top to render the stand collapsible, each leg further including a central web-like portion surrounded by a reinforcing flange portion providing said top portion, a supporting foot portion which is parallel with the leg top portion, a generally flat radially outer edge which extends generally perpendicularly from its said foot portion toward said leg top portion to a distance between the leg foot portion and top portion, and then tapers upwardly and inwardly toward the leg top portion.
Claim 2
Dependent Claim
129 words
A supporting stand comprising a top providing an upwardly facing supporting surface and a downwardly facing surface providing a plurality of channels, and a plurality of legs, each leg having a top portion for engagement with a respective channel on the downwardly facing surface, the legs being readily disengageable from the top to render the stand collapsible, each leg further including a central web-like portion surrounded by a reinforcing flange portion providing said top portion, a supporting foot portion which is parallel with the leg top portion, a generally flat radially outer edge which extends generally perpendicularly from its said foot portion toward said leg top portion to a distance between the leg foot portion and top portion, and then tapers upwardly and inwardly toward the leg top portion.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 and further comprising a brace and a protrusion on each leg for engaging the brace for holding the legs in spaced-apart relation to one another, the protrusion on each leg being located intermediate the top portion and foot thereof, the brace holding the intermediate portions of the legs in spaced-apart relation.
Claim 4
Dependent Claim
11 words
The apparatus of claim 2 wherein the brace is generally ring-like.
Claim 5
Dependent Claim
18 words
The apparatus of claim 3 wherein the channels extend generally radially from substantially the center of the top.
Claim 6
Dependent Claim
176 words
A supporting stand comprising a top providing an upwardly facing supporting surface and a downwardly facing surface providing a plurality of channels extending generally radially from substantially the center of the top, and a plurality of legs, each leg having a top portion for engagement with a respective channel on the downwardly facing surface and a foot portion, the legs being readily disengageable from the top to render the stand collapsible, a ring-like brace, a protrusion on each leg for engaging the brace for holding the legs in spaced-apart relation to one another, the protrusion on each leg being located intermediate the top portion and foot thereof, the brace holding the intermediate portions of the legs in spaced-apart relation, each leg including a leg outer edge and a leg inner edge, the leg outer edges extending generally perpendicular to the top, the protrusion on each leg being located on the outer edge thereof, the brace being slidable downwardly over the top of the stand and downwardly along the leg outer edges into engagement with the protrusions.
Claim 7
Dependent Claim
176 words
A supporting stand comprising a top providing an upwardly facing supporting surface and a downwardly facing surface providing a plurality of channels extending generally radially from substantially the center of the top, and a plurality of legs, each leg having a top portion for engagement with a respective channel on the downwardly facing surface and a foot portion, the legs being readily disengageable from the top to render the stand collapsible, a ring-like brace, a protrusion on each leg for engaging the brace for holding the legs in spaced-apart relation to one another, the protrusion on each leg being located intermediate the top portion and foot thereof, the brace holding the intermediate portions of the legs in spaced-apart relation, each leg including a leg outer edge and a leg inner edge, the leg outer edges extending generally perpendicular to the top, the protrusion on each leg being located on the outer edge thereof, the brace being slidable downwardly over the top of the stand and downwardly along the leg outer edges into engagement with the protrusions.
Claim 8
Dependent Claim
48 words
The apparatus of claim 5 wherein a vertical stack of such stands is provided, the radially inner edge of each leg being provided with a stacking portion, the stacking portions of the legs of one stand being spaced apart to engage the top of the next subjacent stand.
Claim 9
Dependent Claim
57 words
The apparatus of claim 1 wherein the top of each leg comprises a generally T-shaped portion and the channel for receiving the top portion of a respective leg including a pair of facing, generally L-shaped elongated protrusions on the downwardly facing surface, the facing L-shaped protrusions receiving the top bar of the generally T-shaped leg top portion.
Claim 10
Dependent Claim
205 words
A stand comprising a top providing an upwardly facing supporting surface and a downwardly facing surface, a plurality of channels provided in the downwardly facing surface, a plurality of legs, each leg including an upper portion for engaging a respective channel to support the top and a supporting foot portion, the leg upper portions slidably engaging the channels and being disengageable therefrom to render the stand or stool collapsible, the channels being generally radially disposed about a point on the downwardly facing surface, each leg further having a generally radially inner edge and a generally radially outer edge, each leg further including a central web-like portion bounded by the upper portion, radially inner and outer portions, and supporting foot portion, the radially outer edge of each leg including a projection disposed intermediate the top and foot thereof, the stand further including a brace for maintaining the orientations of the legs with respect to the top, the brace being ring-like and slidable vertically downwardly over the top and along the outer edges of the legs, the brace including a plurality of pockets equal to the number of projections for receiving the projections to retain the brace in position intermediate the tops and feet of the legs.
