  • Patent number: 6488119
    Abstract: A folding sawhorse of the type comprising two trestle like frames that are hingedly connected at their tops. The shelf is hingedly attached to a lower strut of one frame and slidably attached to the legs of the opposite frame. The slidable attachment is by means of pairs of pins that are secured to one end of the pivoting shelf and are also yoked to longitudinal ridges that are in the legs of the opposite frame. To open the sawhorse from its closed, storage position, the frames are spread apart slightly, thereby allowing gravity to pull the shelf downwardly and concurrently causing the frames to spread outwardly to their open, working position. The sawhorse will stay in this locked open position without any additional latching mechanisms until the close procedure is initiated.

    Abstract: A stowable knockdown sawhorse can be assembled in two configurations: an operating configuration and a storage configuration. The sawhorse includes a pair of inverted-V-shaped leg members and a saddle having four mounting assemblies--two at each end, one per side. Each leg member has a notched apex that envelops one end of the saddle and is in turn enveloped within an inclined channel formed within each mounting assembly, thereby forming the sawhorse into its operating configuration. Each mounting assembly further defines an exterior bearing surface, the bearing surfaces on like sides of the saddle facing and opposing each other and lying on planes that intersect beyond the saddle working surface to form an angle equal to the apex angle of the leg members. The bearing surfaces are thereby oriented to accept and retain therebetween the leg assemblies when disengaged from the ends of the saddle and inverted between the bearing surfaces to form the sawhorse into its storage configuration.

Each leg has a longitudinal slot with a transverse pin which passes through a bound space defined within a rigid, rectangular-framed strut. Each strut has a pair of longer side members and a pair of shorter side members, and is bound by the pins into the slots of both legs of a leg pair. The strut can be moved to a vertical position whereby the legs of the sawhorse are held together, or the strut can be allowed to drop into a horizontal position where it keeps the legs from splaying farther when the sawhorse is under load. Detent notches in the inner surfaces of the strut permit the sawhorse to resist being collapsed back into its folded orientation.

The cross beam has two supports, one at each longitudinal end of the cross beam, each support having an A-frame shape as the saw horse beam is viewed from an end. Each support consists of a pair of telescoping legs pivotally mounted to brackets on the sides of the aluminum channel, and a brace which is adjustable in length between the pair of legs. Each leg is hollow, tubular, and square in cross section. Each leg has a foot pivotally mounted thereon, the foot having a serrated edge adapted for penetrating the ground in order to firmly anchor the saw horse on sloping ground. The height of the saw horse may be adjusted between thirty-six and seventy-two inches. The saw horse is appropriate for use as a small scaffolding as well as a trestle for general carpentry work.

  • Patent number: 5878839
    Abstract: A support device includes a bracket secured on a base for rotatably supporting a roller and for engaging with and for supporting a work piece. A stick is secured in the base and has an orifice for slidably engaging with a rod which is extended downward from the bracket for allowing the bracket to be adjusted to a suitable height. The bracket includes a pair of blocks for slidably receiving a pair of poles. The poles each includes an extension extended upward for engaging with the work piece and for preventing the work piece from moving laterally.

  • Patent number: 5865269
    Abstract: A work support device with adjustable length legs used to stabilize the work support on an uneven bearing surface, that is height adjustable, allowing the user to raise a supported work piece to a desired height, and that is levelable in that the user can adjust the work support to level the work piece being supported. Both the adjustable length legs and the height adjustable upper beam are self locking. Unlocking the height adjustable upper beam to allow downward movement is accomplished with finger pressure on a rod. Unlocking the adjustable length leg is accomplished with finger pressure on a lever. The self locking action occurs immediately upon releasing pressure on either the rod or the lever.

  • Patent number: 5839540
    Abstract: A foldable sawhorse that can be shipped and stored in a small volume. The sawhorse comprises first and second leg assemblies and a plurality of spacing members. The leg assemblies are preassembled at the factory. The spacing members are bolted onto the leg assemblies by the end user. Hinges are formed by tubular hinge members attached to the upper ends of the leg members; the hinge members are either nested one within the other to form the hinge assembly, or separate pin members can be provided that extend through two hinge members. The sawhorse is inexpensive to manufacture and ship but sturdy and flexible in use.

  • Patent number: 5729215
    Abstract: A battery operated safety strobe barricade, particularly suited for school crossings. The use of a battery pack that is rechargeable and can be separated from the barricade enables the apparatus to be particularly well suited to safety situations where high visibility and weight are considerations. The A-frame stand section is fabricated from low weight aluminum so that it can be carried by even the smallest crossing guard. The rechargeable battery pack features a dual rate charger so that the unit can be left to charge continuously. The battery pack has a low voltage disconnect feature so that catastrophic battery discharge is avoided thus prolonging the life of the battery. A high visibility strobe light mounted on a telescoping pipe enables the unit, despite its light weight construction, to provide a warning beacon that can be easily seen at great distances, even in the daylight.

  • Patent number: 5704450
    Abstract: A portable and foldable workhorse. A pair of parallel rails includes an open space between the rails, the rails providing a flat top support surface and a bottom support surface. A pair of leg assemblies each includes a top surface. A center beam is attached to each leg assembly so that each center beam is moveable in the open space between said pair of rails. A shaft passes through and perpendicular to the parallel rails and through and perpendicular to the center beam. The shaft pivotally connects each center beam to the rails to allow movement of each leg assembly between a usage position wherein the rail bottom support surface rests on the top surface of the leg assemblies and a storage position wherein the leg assemblies will move radially about a pivot point on the top rails.

  • Patent number: 5647455
    Abstract: A foldable sawhorse comprising first and second leg structures each having a hinge member integrally formed therewith. One of these hinge members is an outer hinge member having a passageway extending therethrough. The other hinge member is an inner hinge member adapted to extend through the passageway in a way that allows the leg structures to rotate relative to each other about a pivot axis. An engaging member is attached to the outer hinge member such that, when the sawhorse is in use, the engaging member is appropriate for engaging a workpiece or other surface to be supported. The hinge members as described above engage each other in a manner that creates a very strong and durable pivot or hinge mechanism. Locking assemblies are employed to fix the sawhorse in an open configuration and allow it to be closed into a closed configuration for storage.
