The latch 41 is intended to ride over catch 47 with a camming motion and may be released from the catch by a tool such as a screw driver which is inserted into the recess 43 of FIG. 6 are designed to be aligned and be interleaved with the hinge post 61 in FIG. Greater strength is achieved in the latter construction. The sidewalls may support the latch 41, as well as the hinge posts 62, or the latch and hinge posts may be supported jointly by the sidewalls and the top wall 71. ![]() 6 shows one of the downwardly extending leg members 53 having sidewalls, as well as a top wall 71 spanning the sidewalls and closing them off at their uppermost extent. Usually an imaginary vertical line will bisect angle D when the sawhorse legs are open.įIG. The angles B and C are selected to be the same for both leg members and are selected so that a comfortable working angle, D, between opposed legs at maximum separation is preferably less than 45° and somewhere near 30°, although this value is not critical. ![]() Conversely, as the angle C becomes smaller, so does the angle B. As the angle C becomes greater, the angle B also becomes greater. This angle of truncation of the lower portion of central bracket member 31 may be indicated by the angle C. Angle B has no definite value because the size of the angle depends on the angle of truncation of the lower periphery of the sidewalls of lower portion 35 of central bracket member 31. This is generally defined by the angle of truncation of the upper portion of the sidewalls of the leg members. The angle defined between the downwardly extending legs 53, 55 depends upon the angle formed by the upper periphery of the sidewalls, in particular the relation between the angle which the leg members make with the central bracket member. The bracket of the present invention is not restricted to use with wooden beams other beam materials could be used. The legs are of equal length, with an angle between opposed legs, such as legs 21, 23 not exceeding 45 degrees. Typically, each of the legs 21, 23, 25, 27 is approximately three feet long while the horizontally transverse beam 28 is usually longer, approximately four or five feet long. The beams which are used to form the sawhorse are typically wooden beams, such as two-by-fours, cut to convenient lengths. The present invention contemplates brackets on opposite ends of the horizontal beam of a sawhorse, but a bracket of the present invention, modified slightly, could be used at intermediate support points as a trestle. Ordinarily, only two sawhorse brackets are used to form a sawhorse, but for long spans, intermediate sawhorse bracket supports can be provided. 1, a sawhorse 11 is shown having the left hand bracket 13 and the right hand bracket 15, both providing support for junctions of beams.
