Abstract
A collapsible stand having a top (14) formed by two mating leaves (15, 17) and supported by legs (28, 30, 32, 34). The legs are pivotedly joined to braces (20, 22, 24, 26) underlying the leaves. The components of the stand pivot with respect to one another so to allow the stand to be easily erected and collapsed. However, due to interaction between at least one of the braces and at least one retainer (64) on the underside of one of the leaves the stand cannot be collapsed without initial planar movement of the leaves away from one another. Since such movement is rare during normal usage, the stand is strong and secure during normal usage. A pair of brackets (80, 82) for holding dimensional lumber (79) may be attached to the braces. When the lumber is placed in the brackets, the stand is further secured in its erect position.
