A novel system for constructing smooth-faced metal framing and novel tracks and track connectors therefore. The system and connectors of the present invention utilize metal framing tracks that demonstrate a U-channel configuration having a base, sidewalls with at least one recess channel formed longitudinally therein, and marginal lips that extend inward from the sidewalls. A variety structurally related connectors, comprising at least a connector body, lip or base flange, and two lip receiving grooves, are described. These connectors are capable of interconnecting metal framing performing all framing functions including, without limitation, floor and ceiling joists, top and bottom plates, roof rafters, roof rims, window sills, trusses, headers and wall studs. The connectors lock into place within the track and are secured from the inside using fasteners applied into the non-surface aspects and / or recess channels of the track. The track connectors demonstrate three dimensional rigidity and a box-like fit within the metal framing tracks to form joints that are strong, durable and precise. The framing system using the track connectors of the present invention leaves the outside surfaces of the framing members smooth and continuous, without protruding fastener heads or interruptions of any sort. The resulting smooth outside surfaces can be covered much more easily and inexpensively than the uneven and generally awkward outside surfaces presently encountered in metal framed structures. The manner in which the connectors lock within the tracks promote their safe and efficient installation. The system and connectors of the present invention enables an entire structure to be framed using one type and size of metal framing track cut to appropriate lengths on site.

A metal frame made up of a plurality of linear bars, which have a constant cross section, are obtained by extrusion, and are joined to one another by means of welding at structural nodes defined by jointing bodies provided with pockets for housing the linear bars. The jointing bodies have box type structures and are made up of the union of respective a load-bearing element, which is obtained by extrusion and has a given direction of extrusion, with a pair of plane closing metal sheets, which are set perpendicular to the direction of extrusion and are welded to the load-bearing element on opposite sides of the load-bearing element. The load-bearing element may also be formed by the lateral union of a number of simple elements, each of the simple elements being obtained directly via extrusion and having a given direction of extrusion parallel to the direction of extrusion of the other simple elements, and wherein the simple elements are joined to one another laterally by mechanical slots.

An adjustable articulated bed with separate adjustable leg and head / back assemblies which support an articulating mattress. The invention is manufactured in three pieces specifically designed for economical shipping directly to consumers via United Parcel, FedEx or US Postal, and is easily assembled without tools. The appearance of the bed is similar to that of a standard bed box spring or platform foundation and may be assembled and placed on a traditional metal frame, headboard, or footboard with side rails. Optional adjustable height legs are threadably attachable into support brackets connected to the bottom of each assembly to adjust the overall height of the bed. The three sections include a head support assembly with lifting arms pivotally attached to a head lifting frame and a deck panel attached thereatop to elevate the head and upper body; a leg support assembly with lifting arms pivotally attached to a two-part leg lifting frame with deck panels attached thereatop to elevate the legs; and a stationary center section supports the middle or buttocks area of the user. When the motor is attached between the leg and head support assemblies locking the assemblies together, the center section then slides into place therebetween. No tools, pins, clips or snaps are required for assembly.

A head gimbal assembly includes a micro-actuator, a slider, and a suspension that supports the micro-actuator and the slider. The micro-actuator includes a metal frame including a top support to support the slider, a bottom support to connect to the suspension, and a pair of side arms that interconnect the top support and the bottom support. The top support includes a rotatable plate and connection arms that couple the rotatable plate to respective side arms. A PZT element is mounted to each of the side arms. Each PZT element is excitable to cause selective movement of the side arms. The suspension includes a load beam having a dimple that engages and supports the rotatable plate in use.
