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.degree. 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.
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,
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.
