A temporary upright post includes rail supports for holding temporary lateral guardrails and a mounting system for mounting to a permanent upright stanchion of a permanent railing system for an elevated surface. The mounting system includes a longitudinal bore in the lower portion of the upright post that removably receives the stanchion with a loose fit, and the mechanical securement tightens the post to the stanchion to secure them together for use and loosens to release the post for installation and removal. Example embodiments also include a support bearing that is repositionable to contact and support the post in an elevated position on the stanchion, up and away from the elevated surface, or to disengage from mechanical interference with the stanchion so the post can be lowered to the use position.

A support apparatus 1 for supporting a user in an elevated working position above a ground surface G comprises a frame 60 for supporting a floor portion 20 of the support apparatus and a plurality of leg members 40a, 40b mounted to the frame 60 for supporting the frame above the ground surface G. Each leg member has a foot portion 42 for engaging the ground surface G. Each leg member is rotatably mounted to the frame for rotation about a rotational axis which is substantially perpendicular to the width and the length of the frame and each leg member extends from the frame in a radial direction of the rotational axis, whereby the foot portion is offset from the rotational axis.

A scaffold toeboard system for locking a toeboard between two vertical scaffold members where each vertical scaffold member includes a tubular member having a diameter and an outer shape. The toeboard system includes a toeboard having an elongated member with a fixed terminating end and an adjustable terminating end. The toeboard further includes a front portion, a top edge, a bottom edge, and a rear portion. The toeboard system further includes a second sleeve fixed to the fixed end of the toeboard, and a first sleeve fixed to the adjustable end of the toeboard. Slidably positioned in the first sleeve is a slide lock sleeve. The toeboard system includes a locking mechanism positioned at the adjustable terminating end, to fix the position of the slide lock sleeve to the first sleeve. The slide lock sleeve includes two fingers or tabs extending outwardly from the front edge of the slide lock sleeve. The two fingers are separated by a horizontal distance of about the diameter of a scaffold vertical member.

A kit for erecting a platform. The kit comprises a plurality of quad-chord trusses. Each truss is attachable to others of the truss by eyelets on the ends of the chords. When the chords are spaced horizontally, the eyelet apertures are vertical for receiving pins, which allows a single pin to be inserted in eyelet apertures on one side of the truss so that one truss is swingable horizontally into position for rigid attachment end-to-end by inserting another pin in eyelet apertures on the other side of the truss. Each truss comprises a plurality of connector members for attachment to the trusses along their lengths. The kit further comprises a plurality of cross beams having connector members at their ends to mate with and attach to the truss connector members, and a plurality of tie-up mechanisms attachable to the trusses and to which a supporting line from an overhead structure is attachable. The cross beams have overhangs at their ends for overhanging the upper ones of the chords to allow ease of movement along the chords and attachment. A track lies between the chords of each truss to allow movement of bolts along the track into position for insertion into decking apertures for attachment of the decking. The trusses may be foldable for transport and storage.

Improvements in scaffold for providing an elevated structure for working or support. The scaffolding system includes an adjustable stabilizer that uses telescoping tubing with locking pins that fix the length of the stabilizer. An access gate provides both access to inside the elevated structure and safety to prevent a person from falling out of a scaffold opening that is secured to the frame of the scaffold. A variety of toe board brackets are configured to be installed on any standard, mid-rail or end frame of the scaffolding depending on the side or corner that is required. A double toe board that allows for a nearly infinite length of scaffolding to provide a protective barrier that is placed near the ground or walking surface of the scaffold working platform. The scaffolding system can be quickly and universally installed and with minimal or no tools in a variety of configurations.

A scaffold toeboard assembly including a toeboard frame having a toeboard coupled to a riser with a first and second end, with a lift handle coupled to the first end, and a toeboard coupled to the second end. The assembly further including a support frame having a vertical support with an attachment member configured to couple to a scaffold swing gate, wherein the riser is slidably coupled to the vertical support.

An exemplary embodiment of the invention includes a locking mechanism for use with the adjustable toe board to retain the toe board in its retracted position when necessary for transport, storage, or when the size of the portion of the platform the toe board will be used in requires the toe board to be in its fully collapsible state. The locking mechanism may be comprised of a latching member that is capable of automatic locking when the adjustable toe board is moved into its substantially retracted position. Further, the instant invention may be provided in any number of varying adjustable lengths to accommodate the various platform sizing through the use of a uniquely shaped wedge pin that is used with a fork to couple adjustable or non-adjustable toe boards to scaffolds and the like.

An apparatus for supporting workers and materials above-grade on both the cave and gable ends of a structure is disclosed. The apparatus can be combined with one or more additional staging apparatuses to create a staging system for the support of persons or materials while work is being done on a structure, e.g., roofing, siding, etc. The modular design of the apparatus simplifies installation, such that it can be readily attached to a roof or other support member of a structure by a single person, and facilitates the adjustable vertical positioning of people or materials along the walls of the structure. The staging system can also include a rail member for safety support and alternative scaffolding arrangements.

A scaffolding arrangement for a building outer wall, comprising a plurality of anchor bolts arranged at a distance from each other at least in the horizontal direction, including tube clamps connected to the anchor bolts, a horizontally extended rail, the rail being fixed to the tube clamps, a scaffolding as well as a connecting device for fixing the scaffolding to the rail. The connecting device provides a first coupling encompassing the rail as well as a second coupling encompassing a tube element of the scaffolding and a coupling connector for connecting the first coupling to the second coupling.

A post for a temporary safety rail system comprising a base for reversible engagement with a floor, a rail holder to hold a rail in reversibly fixed engagement with the post and a plurality of components which are together operable to adjust the height of the post.
