Abstract
Abstract The disclosed collapsible stand has two sets of opposed legs extending radially from a tubular hub support, the stand being of the type that is collapsed or set up by rotating one set of legs relative to the other set of legs about the hub support until the legs are at 90° to each other. Each leg is formed of an elongated rod back folded on itself to present inner and vertically spaced inner ends that are secured to the discs mounted on the hub support with an outer center portion of the back folded rod engaging the floor and serving as a foot for the stand. The inner ends of the legs are sandwiched between a pair of discs movably and rotatably mounted on the tubular hub support. Two pairs of locking or detenting tabs are upstruck from each of the lower discs, each pair of tabs being spaced apart to define a leg receiving slot therebetween. Preferably, the inner ends of the legs are each disposed between a pair of detents to provide a firm and stable support. The resiliency of the back folded rods of the inner support element urges the rod ends into the slots between the tabs and a squeezing of the inner ends of the rods will shift the inner ends from the detent slots whereby a subsequent turning of the legs and their discs allows the legs to be collapsed to positions adjacent each other. The stand is economically fabricated and yet has a pleasing appearance in that the upper discs are unmarred and cover the detent tabs.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
201 words
A collapsible support stand being erectable into a locked position, said stand comprising a central support shaft, four legs having outer ends for engaging the floor and inner ends for attachment to said shaft, each of said legs having an upper segment and a lower segment extending from said outer ends toward said support shaft, a first upper support mounted on said shaft for axially sliding movement, inner ends of one pair of legs attached to said upper support, a lower support mounted on said shaft and movable axially along said shaft, inner ends of a pair of legs secured to said lower support, and detent means formed on at least one of said supports having an axially directed opening for receiving therein the inner ends of the other set of legs, said inner ends snapping into said detent openings when they are rotated into aligned and detenting position in which the legs are in said openings and are held by said detent means against rotation therefrom, said detented leg ends being removable from said detent openings by being moved axially and then turned therefrom to allow the pairs of legs to be swung toward each other to collapse the stand.
Claim 2
Dependent Claim
201 words
A collapsible support stand being erectable into a locked position, said stand comprising a central support shaft, four legs having outer ends for engaging the floor and inner ends for attachment to said shaft, each of said legs having an upper segment and a lower segment extending from said outer ends toward said support shaft, a first upper support mounted on said shaft for axially sliding movement, inner ends of one pair of legs attached to said upper support, a lower support mounted on said shaft and movable axially along said shaft, inner ends of a pair of legs secured to said lower support, and detent means formed on at least one of said supports having an axially directed opening for receiving therein the inner ends of the other set of legs, said inner ends snapping into said detent openings when they are rotated into aligned and detenting position in which the legs are in said openings and are held by said detent means against rotation therefrom, said detented leg ends being removable from said detent openings by being moved axially and then turned therefrom to allow the pairs of legs to be swung toward each other to collapse the stand.
Claim 3
Dependent Claim
65 words
A collapsible support stand in accordance with claim 1 in which said upper and lower supports are discs mounted on said shaft and in which another upper and lower disc is mounted on said shaft with inner ends of a pair of legs attached thereto, said inner ends of the legs being sandwiched between a pair of upper discs and a pair of lower discs.
Claim 4
Dependent Claim
46 words
A collapsible support in accordance with claim 2 in which said detent means comprises integral tabs struck from a disc and spaced apart to define said opening for receiving the inner ends of a pair of legs not affixed to the disc having said tabs therein.
Claim 5
Dependent Claim
44 words
A collapsible support in accordance with claim 3 in which said detent means are formed on two said discs and in which tabs are struck from the disc at diametrically opposite locations on the same disc to provide two detenting locations on each disc.
Claim 6
Dependent Claim
28 words
A collapsible support in accordance with claim 4 in which said detent means are formed in the lower ones of the discs of said lower pairs of discs.
Claim 7
Dependent Claim
66 words
A collapsible support in accordance with claim 1 in which said detent means comprises a pair of tabs struck from the support at spaced locations to define therebetween the openings for receiving the inner leg ends therein, said tabs having curved surfaces for camming the inner rods in an axial direction to compress the legs which then expand and snap into the opening between the tabs.
Claim 8
Dependent Claim
201 words
A collapsible stand, comprising a central hub support, sets of support elements mounted on the hub support and extended radially therefrom, the sets of support elements being movable relative to each other between a collapsed position whereat they are in near parallel relation and a set up position whereat they are in sharp angular relation, each set of the support elements being formed of upper and lower annular discs fitted over the hub support and an elongated rod back folded on itself and presenting upper and lower end segments secured to the respective discs and a medial foot segment, the discs of one set of support elements being located outwardly adjacent the discs of another set of support elements and the adjacent upper discs and the adjacent lower discs sandwiching the respective upper and lower rod end segments therebetween, a pair of locking tabs formed from one disc of each of the adjacent discs and defining a slot therebetween adapted to receive and straddle in locking relationship the respective rod segment secured to the adjacent disc when the stand is in the set up position, and means constraining the axial location of the discs of the outer set of support elements.
Claim 9
Dependent Claim
201 words
A collapsible stand, comprising a central hub support, sets of support elements mounted on the hub support and extended radially therefrom, the sets of support elements being movable relative to each other between a collapsed position whereat they are in near parallel relation and a set up position whereat they are in sharp angular relation, each set of the support elements being formed of upper and lower annular discs fitted over the hub support and an elongated rod back folded on itself and presenting upper and lower end segments secured to the respective discs and a medial foot segment, the discs of one set of support elements being located outwardly adjacent the discs of another set of support elements and the adjacent upper discs and the adjacent lower discs sandwiching the respective upper and lower rod end segments therebetween, a pair of locking tabs formed from one disc of each of the adjacent discs and defining a slot therebetween adapted to receive and straddle in locking relationship the respective rod segment secured to the adjacent disc when the stand is in the set up position, and means constraining the axial location of the discs of the outer set of support elements.
Claim 10
Dependent Claim
46 words
A collapsible stand according to claim 7, wherein the back folded rod of at least the inner set of support elements has resiliency to bias the discs secured thereto axially outward and against the discs and rod end segments of the outer set of support elements.
Claim 11
Dependent Claim
26 words
A collapsible stand according to claim 7, wherein each of the tabs is curved upwardly from its disc toward one another and toward the adjacent disc.
Claim 12
Dependent Claim

A collapsible stand according to claim 7, wherein each set of support elements has two elongated rods each back folded on itself and disposed when secured to the respective upper and lower discs in generally aligned relationship on opposite sides of the hub support.
Claim 13
Dependent Claim
