Abstract: A truss structure is suitable for supporting lighting fixtures is provided which employs wheeled leg carriages to support such trusses during transport. Each leg carriage has two legs, one extending vertically from each end of an elongated crossmember. A caster is attached proximate to the bottom of each leg. The top of each leg can be inserted in a tube fixed in a corner of the truss, elevating the truss so as to produce a volume below the truss structure into which lighting fixtures and other loads can safely project during transport. The ground clearance produced is determined by the amount that the leg is inserted in the tube and an improvement allows the retention of a mechanical stop in the tube that determines the amount of insertion allowed. Stiffeners used to brace two leg carriages, one to the other, are provided with features that allow their use in forming a cart for storing leg carriages not in use.

Abstract: A truss structure is suitable for supporting lighting fixtures or other loads both in use and in transport. The truss has at least four elongated chords defining between said chords a first volume generally rectangular in cross-section. In transport, the truss is supported substantially above a surface by castered carriages bearing upon that surface, the carriages connected to said truss and in a first position producing an additional volume between said first volume and said surface. The carriages are attached to the truss so as to permit their rotation between said first position and at least a second position suitable for use while remaining connected to said truss.

In one embodiment, the invention generally relates to a scaffolding frame that includes at least two vertical support members, at least two legs for each of the vertical support members that extend outward and away from the vertical support members, in which each leg is rotatable around the vertical support members and lockably coupled to each of the vertical support members, the scaffold frame configured such that in a deployed state, a base member of each leg and bottom of each of the vertical support members contact an underlying surface.

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: An adjustable building construction shore has an inner tubular member extending internally of an outer tubular member and displaceable longitudinally of the outer tubular member, the inner and outer members having projecting and recessed longitudinal portions slidably interengaged and preventing relative rotation of the inner and outer tubular members. Openings extending transversely through the inner and outer tubular members are spaced apart longitudinally of the inner and outer tubular members, and retainer members extend through the openings for securing the inner and outer tubular members against relative longitudinal movement. A screw jack supports a lower end of the shore.

Abstract: A shoring device that utilizes an accessory assembly mounted to a vertical tubular member of a tubular scaffold assembly to receive a shoring member therethrough. With an adjustable threaded ring mounted over the threaded portion of said accessory assembly, a supporting surface or edge is provided to a locking pin that passes through cooperating slots in the accessory assembly and radial through holes in the shoring post member to keep the post member and the accessory assembly at a fixed position with respect to each other. The lower most end of the threaded portion comes in abutting contact with the upper end of the scaffold vertical member thus transmitting the bearing load therethrough. A user can selectively adjust the effective length of the scaffold and shoring assemblies by rotating the ring assembly.
