Abstract: An architecture is presented that consolidates scaffold stair units to one unit with a multi-fit hook device. The multi-fit hook device for scaffolding comprises a bracket with an opening at one end. The bracket further comprises slotted holes formed in the bracket, outside the opening to aid in securing the multi-fit hook device to an access way. Hardware, such as screws or bolts, is inserted through the slotted holes to secure the bracket to the access way. The opening at one end of the bracket is formed to accept scaffold tubing indeterminate of size, and can be used on any scaffold system. Thus, the opening is not scaffold tube style specific and does not require a separate unit for each scaffold system. Instead, the multi-fit hook device permits the same access way to be used on multiple scaffold systems.

Abstract: A tubular frame scaffolding system including base pads, vertical trusses, work platforms, access ladders, diagonal support braces, horizontal guard rails, intermediate guard rail panels, top guard rail panels, top guard rail posts, and toeboards. The guard rails and the toeboards act as safety devices to protect against accidental falls during the use of the tubular frame scaffolding system.

Abstract: Boat stand assemblies for dry dock maintenance or storage of boats with and without keels including two or more rigid frames of adjustable width each including a pair of struts of adjustable height, the frames being connectable by cross braces to provide a complete stand and further including a keel stand assembly similarly constructed of height and spacing adjustable struts.

Abstract: This invention provides a guard rail post for use on scaffolding of the type used in the construction of buildings. The guard rail post comprises an elongated member having securing means for securing the guard rail post to a vertical support member of the scaffold, positioning means for mounting the guard rail post in fixed relationship to a scaffold work platform and means for connecting guard rails to the post at a fixed distance above the work platform.

Abstract: An apparatus for securing an adjusting screw having a nut thereon to an hollow leg of a scaffolding frame to prevent loss of the adjusting screw when the scaffolding frame is tilted or raised. The apparatus includes a swivel that allows turning of the handle nut while the adjusting screw remains secured to the leg of the scaffolding frame.

Abstract: A scaffold connector assembly for connecting upright members to cross members to form a scaffolding structure. The scaffold connector assembly is adapted to connect upright members with cross members so as to form both orthorhombic and monoclinic substructures. The scaffold connector assembly is further adapted to interconnect both the orthorhombic and monoclinic substructures so as to form closed polygon scaffolding structures.
