Abstract: A device for supporting a limp disposable container in a generally open position to receive material and for preventing the container from collapsing as material is inserted therein has rim means for releasably engaging portions of the container peripherally about an opening in the container and for supporting these portions in an open position, second means defining a base for providing stability for the device relative to a surface upon which the device is positioned, strut means interconnecting the rim means and the second means for maintaining a desired spaced relationship therebetween and mounting means for securing the rim means and the second means to the strut means to provide a rigid support device for the limp container. The device may be provided in unassembled kit form of primarily straight tube sections suitable for assembly in an easy and facile manner.

Abstract: A fence is assembled from tubular posts and open-ended tubular cross-pieces the ends of which are slidably supported on the posts and selectively secured in one of several discrete positions, for example by engaging transverse slots in the lower face of the cross-pieces on tabs in apertures in the posts. In another arrangement, flaps in the posts are folded in to form apertures slidably receiving ends of the cross-pieces, which are secured by selectively engaging pins in aligned holes in the flaps and cross-pieces. The fence may include a rectangular gate frame formed by folding a suitably cut-out tubular piece.

Abstract: A modular shelf system formed of injection molded structural elements including shelf modules and column modules. The shelf modules have through openings and the column modules have interlocking ends which are received in said openings so that the column modules extend from both sides of a shelf module when assembled.

Abstract: An unthreaded, slip-on fitting for connecting a length of structural pipe to another length of structural pipe and/or to a stationary structural member such as a floor or wall, which is usable in building scaffolding, shelving, railing and the like. The body of the fitting has extending from it a pair of spaced parallel arms between which a locking element is pivotally mounted on a transverse pin spanning the arms. A set screw which is accessible from the exterior of the fitting body when the arms are inserted into the interior of a pipe to which the fitting is connected, engages a portion of the pivotal locking element extending into a cavity in the fitting body communicating with the slot. When the set screw is advanced inwardly, the locking element is pivoted, moving outwardly in opposite directions a pair of pipe clamping projections on the locking element, to grip the interior of the pipe, thereby securing it to the fitting.

Abstract: A clamp-connector for joining tubular members. The tubular members need not be threaded, welded, drilled, or bolted. The clamp-connector consists briefly of a sheet metal bracket formed with quarter-round portions for cradling the tubular members and openings for receiving the clamps. The clamps are standard worm gear clamps with perforated straps. The brackets may be shaped to hold the tubular members in two or more planes.

Abstract: A furniture assembly fixture having a first fixture section comprising a casing adapted to be embedded in a first furniture part, a second fixture section adapted to be fastened to a second furniture part, the casing having a flange with a lug or lugs, the flange also carrying an adjusting plate for a furniture hinge.

Abstract: A hub is employed in forming an ornamental sunburst from a plurality of spokes. The hub includes an annular base plate and an outer hub having a tubular rim and an outer wall. Radially spaced wedge members on the interior surface of the outer wall define spaces for the spokes, and the base plate is engaged over the spokes and wedge members.

Abstract: A method of constructing a double-sigmoid connector from a pair of arcuate elbows comprising the steps of: forming an outlet in a portion of the outer periphery of each of the elbows, said outlet having an annular wall extending outwardly of the outer periphery of each elbow, and welding the outlet walls together.

Abstract: Waterproof joint for field assembly consisting of two waterstops each having a planar face and a U-shaped junction member fastened to the faces of the water stops.

Abstract: A system of structural members comprising a basic structural member having secured to opposite sides thereof a pair of corresponding plates which extend outwardly from the sides of the basic structural member, and are adapted to enable two secondary structural members to be secured thereto by means of releasable fasteners, and at least one further structural member having an end provided with two opposite recesses shaped to allow said end to fit between the plates with heads of any fasteners abutting the plates on the insides thereof located in the recesses, this end further having a flange for securing it to the basic structural member.

Abstract: A coupler is disclosed for connecting a plurality of laths of assembly of multi-component modular structures. The coupler comprises a plurality of channelled seats extending from the center of the coupler. Pins engage the bifurcated terminals of the laths, which are kept in place by said channelled seats, and may be snapped into varied structural configurations. Variants of the coupler are also described.

Abstract: Framing members of metal are produced from three tubular elements in parallel adjacent relationship held together by transverse fasteners. Sealing strips are located between the adjacent surfaces of the elements and subjected to pressure by the fasteners. In one form of the invention each of the fasteners comprises two pins, each of which passes through two elements so that the pin ends lie in opposed juxtaposition within a common element of the three and are secured together by collets. Alternatively, welded studs are employed. The members are joined together to form a frame by internal blocks shaped to suit the shape of the joint, e.g. angle or tee, and secured by clamping screws or riveting.

Abstract: A steel box-column for steel structures comprises a pair of steel channel members each having beam-column connecting diaphragms set inside thereof at respective positions whereat flanges of beams are welded to the exterior of the channel members. The flanges and the web of each steel channel member are welded to three sides of each of the connection diaphragms. A pair of the steel channel members are welded to each other at ends of their flanges facing each other.

Abstract: Disclosed herein is a system in which a number of structural members are used to form compound structures, particularly structures for furnishings, wherein there is a first connector essentially consisting of a central tubular body with a prismatic or cylindrical surface provided with at least one slot of a given length, open at one end and extending upwards along the median plane on each face of the said surface and of a number of crossed fins protruding from the top and from the bottom of the said central body, the intersection line of the said fins coinciding with the axis of the said central body; a second connector identical to the first, except for the fact that the said central body is sealed at the top by a flat surface; a bar having in the proximity of both of its ends, a slot, open at one end, which fits into one of the said slots in the central body of the connector; a tube of a section identical to that of the central body of the connector; the said fins being designed to slide into the said tube

Abstract: A guiderail system for floor-mounted storage racks which is located generally adjacent the access aisles. Tubular guiderails are supported by brackets which include a pair of sockets extending in opposite horizontal directions which sockets are proportioned to closely interfit within the tubular guiderail. A main plate portion of the bracket is disposed under the storage rack column or support to transfer the load carried by the storage rack to the bracket and thus stabilize and rigidify the guiderail system.
