Abstract: The multipurpose sawhorse end frame has a top section defining center and lateral slots for receiving 2?×4? beams and central slots for 2?×12? planks, a central section with center slots for receiving 2?×4? beams and lateral support bars for supporting 2?×12? planks, and a bottom section having feet for supporting the frame. A plurality of diagonal braces maintain rigidity of the end frame and provide the end frame with structural strength. Two or more end frames may be configured as a sawhorse, a scaffold, a workbench, a table, or other temporary construction accessory using scrap lumber and without fasteners. The multipurpose sawhorse end frame may be made from lightweight aluminum or other suitable material.

Abstract: The present invention provides a metal, height-adjustable, folding sawhorse, easily assembled in moments, strong enough for heavy loads, and, when no longer needed, easily collapsed into a compact, flat package for storage or transport. Manufactured by the Fabricated Metal Products industry, the Clydesdale Saw Horse is fabricated of a lightweight steel allow or a fairly heavy gauge aluminum alloy.

Abstract: An improved portable work bench includes a structural body, and a platform disposed on the structural body. In addition, the platform includes a cam mechanism for locking the position of the platform along the structural body. Further, the portable work bench may include a plurality of legs for supporting the structural body. The structural body may be tubular and preferably has a square cross-section. Accordingly, the user need only place the platform in any position along the length of the structural body and move the cam mechanism to lock the platform in place. The cam mechanism may include a cam pivotally attached to the platform near the structural body, so that when the user rotates the cam, the cam contacts the structural body, locking the platform. A plate may be disposed between the cam and the structural body. The plate may have a hook portion, which contacts the bottom surface of the structural body.

Abstract: A saw horse includes leg support members that have top and bottom portions, and planar front and rear surfaces. The top portions have a notch formed therein. Coextensive support arms are pivotally connected to the leg support members. Each support arm has a top and bottom edge, and is adaptable between folded and unfolded positions. A first support beam is removably positionable into the notch, extending downwardly. The first support beam has opposed end portions situated away from the leg support members and has a major longitudinal length thereof horizontally intercalated between the leg support members. A second support beam is removably positional in the notch and has a bottom surface engaged with the first support beam, defining a work surface. Rubber pads are engaged with the bottom portions of the leg support members, assisting to maintain the saw horse at a stable position during operating conditions.

Abstract: A work piece support assembly can be assembled in either an operating configuration or in a flattened coplanar configuration for storage. The support assembly includes a pair of leg assemblies, one each for the proximal and distal end portions of an elongated rail support member. Each end of the rail support member has a portion having two leg socket assemblies. Each socket assembly has a first and second socket with respective first and second centerlines that may be non parallel and intersect at a predetermined point. Each leg assembly has a stem assembly comprised of a first and second stem portion, which are both pivotally coupled to the rail support member through the first and second sockets of each socket assembly. In its operational configuration, the first and second leg of each leg assembly is transverse to the rail support member. In the flattened storage configuration, the leg assemblies counter rotate resulting in each leg assembly being coplanar to the rail support member.

Abstract: A modular channel joint structural system comprising an interlocking system with matching extensions. The extensions slide into matching grooves or channels and are bottled together with only one bolt per joint. In a typical embodiment, aligned members with transverse grooves towards the ends thereof are joined together and to a third perpendicular member with inwardly curved extensions which engage the grooves. The third member includes a corresponding aperture on both sides thereof which is positioned in line with an end notch in the aligned members. A bolt engages the apertures to hold the three members fixedly together.
