Sawhorse bracket assembly

Claim 1

An arrangement for interconnecting a cross member and a pair of legs of predetermined lengths and sizes in converging relation to form a support, said arrangement comprising a pair of bracket assemblies, each said assembly including a main support bracket member having a triangular shaped face plate with a slot of predetermined width extending downwardly thereinto from the apex, with a shelf portion extending outwardly from a first surface of said face plate at the base of said slot, said shelf portions of said pair of brackets being in an aligned opposing relation, each of said brackets further including flanges inclined along each side thereof and extending toward the flanges of the other bracket for receiving and engaging therebetween said legs, and a pair of auxiliary brackets, each one of said pair being associated with a corresponding main support bracket and each comprising a plate portion having a width substantially equal to the width of said slot and being received in said slot, said plate portion having a first section extending outwardly from said first surface of the face plate of said corresponding main support bracket and resting on a corresponding shelf portion with said first section and shelf portion having aligned apertures for receiving a screw fastener to be threaded into the bottom of the cross member and a second section extending outwardly from the opposite surface of said face plate and apertured to receive a screw fastener to be threaded into the bottom of the cross member and further including opposed laterally open notches between said first and second sections receiving the slot forming edge portions of said main support brackets, and each of said flanges having an aperture therethrough adjacent the upper end thereof for receiving a screw fastener to be threaded into the side of the cross member and with the axes of the said apertures in said flanges inclined downwardly to correspondingly position screw fasteners received therein for causing end portions of the flanges to bite into the cross members under influence of the screw fasteners with resultant compression of the flange portions adjacent the edges of the slot causing said edges to snug the adjacent surfaces of an inserted cross member in line with said notches, said cross member being received in the slots of said main brackets and supported on the auxiliary brackets in position for screw fasteners in said apertures to be threaded thereinto for substantially nonwobble support thereof on legs secured between the face plAtes of the main brackets with the aligned apertures in the shelf portions and auxiliary brackets being disposed in substantially the vertical planes of the corresponding apertures at the upper ends of the flanges to correspondingly position screws received therein with the screws arranged in a generally transverse triangular positioning for engagement of corresponding screws with the bottom and sides of the cross member and with the screws through the second sections of the plate portions arranged with the other screws in a generally longitudinal triangular positioning for additional engagement thereof with the bottom of the cross member whereby to provide a close-coupled array of screws transversely and longitudinally of the cross member, said second section of each plate portion including depending flanges with substantially vertical edges to abut the adjacent face of the main bracket for aligning the aperture in each first section with the aperture in the corresponding underlying shelf portion for screw reception therethrough into engagement with the cross member for assembly and facilitating disassembly by permitting ready removel of the auxiliary brackets from the main brackets upon removal of the screw fasteners.
