Abstract: A combined step stool and workpiece support device (4) has a folding frame with a rigid front leg structure including front legs (2,3) and a first support bar interconnecting the front legs at an upper end thereof. The frame also includes a rear leg structure including rear legs (10,11), each being pivoted to a front leg via a first hinge (15, 16) for movement of the rear leg structure between a use position and a storage position. Portions (2a, 3a) of the front legs above the first hinges and the first support bar form a first workpiece support bracket (20). The device includes a pivotable rigid second workpiece support bracket (25) with a pair of arms (25a, 25b), each having a lower end pivotally connected via a second hinge (27, 28) to the frame. The second support bracket is pivotal between a use position and a collapsed position.

Abstract: The present invention provides a frame having variable dimensions, comprising a plurality of telescoping legs arranged in first and second pairs, with each leg of said first pair being rotatably coupled together and each leg of said second pair being rotatably coupled together; and a scissor link mechanism coupled between the legs of said first and second pairs to vary a length of said plurality of legs in response to a distance between said first and second pairs varying. In one embodiment one end of each of said legs of said first pair is rotatably coupled together and one end of each of said legs of said second pair are rotatably coupled together. In this manner, the dimensions of the frame may be varied to accommodate support of a flexible body, such as a plastic bag, paper sack, fabric sack and the like to provide the same with a desired volume and/or an opening of the same with desired dimensions.

Abstract: An adjustable sawhorse that functions as two sawhorses by providing two support members positioned several feet apart. The device is comprised of two rectangular framed leg assemblies that are pivotally attached and operate with a scissor-like motion. Each rectangular framed leg assembly is comprised of a first and second “U” shaped tubular member with the first “U” shaped tubular member having a smaller diameter than that of the second, and with the sides of the first “U” shaped tubular member being slidably mounted inside the sides of the second. The second “U” shaped tubular member of each leg assembly includes two locking knobs to lock the first and second “U” shaped tubular members into place with respect to each other. The device includes two chains interlinking the two rectangular framed leg assemblies and a support member pivotally attached to the uppermost cross bar of each leg assembly.

Abstract: A foldable sawhorse/worktable (10) comprising a work platform (12), a pair of scissor side support assemblies (14) and a pair of cross braces (16) horizontally extending between the scissor side support assemblies (14) for stabilization purposes. Structures (18) are for pivotally mounting top ends of each scissor side support assembly (14) to the underside (20) of the work platform (12). It can be placed into a folded position with the work platform (12) vertical to be conveniently stored and can be placed into an unfolded working position with the work platform (12) horizontal to support various types of power tools and all kinds of construction materials.

Abstract: A sawbuck includes a pivot beam which forms the pivot joint between the legs of at least three X-shaped sets of legs, and also forms a horizontal member of two or more Vierendeel trusses included in the sawbuck. In a preferred embodiment, the sawbuck includes a rigid pivot beam and three foldable X-shaped sets of legs, each set of legs including at least one pair of legs pivotally attached to each other between ends of the legs by the pivot beam. First and second ones of the three sets of legs are pivotally attached to the pivot beam adjacent to respective ends of the pivot beam, and a third one of the sets is pivotally attached to the pivot beam between the first and second sets. A first primary stabilizer beam is attached adjacent to a first end of a first one of the legs of each pair of legs so that the pivot beam, first legs and first primary stabilizer beam define a first Vierendeel truss.

Abstract: A foldable keyboard stand is formed of a pair of elongated leg tubes that are pivotally connected together to form an X-shape which is arranged in an upright position. Horizontally arranged, parallel tubes are secured to the upper and lower ends of the leg tubes to form upper support and lower foot tubes. The support and foot tubes are arranged off-center relative to the axis of the leg tubes so that they extend forwardly, towards a user location, a considerably greater distance than they extend rearwardly. A resilient, foam plastic sleeve is placed upon and substantially covers each of the upper, support tubes opposite extension portions. A resilient, ring-like collar, which is higher than the support upper surfaces, are positioned upon the opposite ends of the support tubes so that a generally flat keyboard may be rested upon the sleeve covered support tubes and laterally restrained between the end collars.

Abstract: A portable support stand, convertibly used either as a stool or tree stand platform, is configured with adjustably hinged frame members, at least one of which is furcated, for being interspaced, crossed and pivotally joined to provide a stool when fitted is a sling seat or to provide a tree platform when toggled between limbs in the crotch of a tree.

Abstract: A folding sawbuck is disclosed that combines a cross frame design with integral vertical members, allowing a large quantity of logs or other wood to be cut into firewood at one time. The use of independant support assemblies, secure by horizontal members, provides an obstruction free cutting path that gives fast and safe cuts under all types of conditions, with all types of wood. The sawbuck is designed to be folded compactly for storage, and then opened for use with a minimum of difficulty. Two different embodiments of the invention are disclosed, each design using a different means for forming the "X"-frame portion of the main support assemblies. The invention is designed as a kit, with all parts pre-cut for easy assembly, or it can be manufactured fully assembled. The sawbuck can be constructed from either wood, metal or plastics.

Abstract: A rigid sawbuck assembly to be supported by four lengths of lumber such as 2.times.4's which form foldable "X" shaped legs. An elongated axially extending cross bar axle extends between two pairs of juxtaposed metal plates, a pair of which are at each opposite end thereof, journalled on said pipe for rotation. The plates are attached to the lengths of lumber and include lugs on the inner plates of each pair extending from the side edge into the path of rotation of the side edge of the outer plate of each pair to serve as a stop. A cross brace is attached between the lower portions of the innermost legs so that said sawbuck is rigid, foldable, compact and can be stored. Because of the flat plate structure, 2.times.6's or other sizes of lumber may be used for the legs.

Abstract: A sawhorse including a pair of V-cut-out or shaped side portions joined together by a vertical hinged portion. The sawhorse is openable for use and when folded side by side together can easily be carried.

Abstract: A saw buck bracket includes a pair of bracket elements disposed with their web portions in abutting surface contact and having parallel sidewall portions extending perpendicularly to their web portions along two opposite sides thereof. The web portions of the bracket elements have an arcuate slot with the slots of the cooperating bracket elements being disposed at opposite ends of the sidewall portions. Between the arcuate slots is a large diameter pivot provided by a circular aperture in one web portion and a circular lip on the other web portion which extends through and is secured behind the one web portion. Rivets seated in one web portion are slidable in the arcuate slot of the other to define the limits of pivoting of the bracketelements and to assist in maintaining the bracket elements in assembly.
