REUSABLE QUICKLY ASSEMBLED AND QUICKLY KNOCKED DOWN WORK SUPPORTS, USED SINGLY AND WITH OTHERS FOR MANY PURPOSES AND CONVENIENTLY CARRIED AND STORED ABSTRACT Work supports, which are quickly assembled and quickly knocked down, are used singly and with others, with and without accessories, for many purposes. When not an use, these work supports are conveniently carried and stored. Each work support has a pair of leg assemblies, wherein each leg has an overall planar triangular shape made of continuous pipe, arranged, via bending, with a horizontal lower pipe side for ground or floor contact, and two upstanding opposite slanting pipe sides, which are secured by welding to the underside of a larger pipe. This larger pipe serves as a horizontal cross bar sleeve. Each triangular planar shaped continuous pipe leg is positioned at a five degree cant with the horizontal cross bar sleeve. Also, each leg has two short length bracing pipes, each extending on a forty five degree angle between a respective upstanding opposite slanting pipe side and the underside of the larger horizontal cross bar sleeve, and so welded, to increase the strength and to eliminate flexing of each leg assembly of each work support. Each horizontal cross bar sleeve has a threaded hole to receive a threaded locking bolt, and non threaded aligned holes to receive a drop in depending threaded bolt, which integrally supports above an integral channel section, which is ready to receive a piece of two by four or two by six lumber, etc. at one of many selected angles. Moreover, each work support has a horizontal pipe of selected length, or a telescoping set of horizontal pipes, which are insertable at their respective ends into respective horizontal cross bars, and locked upon turning the locking bolts to complete the basic assembly of one work support. The bottom of each horizontal lower pipe side is coated with a non-scuffing, non-slipping, and non-conducting insulating material.
