Abstract: A guard rail scaffold assembly comprises a plurality of assembly members carrying horizontally extending guard rails. Each assembly member comprises an elongated base member attachable by a releasable connector to a fastener pad fastened to an above-ground structure surface. The connector allows pivoting movement of the base member for adjustment of the base member to be parallel to the surface. The base member also carries surface engaging members on opposite sides of the connector which engage the structure surface to maintain the base member parallel to the structure surface. A first post member extends from the base member and, when the scaffold is mounted on the guarded surface, this constitutes a guard rail support member or has a guard rail support member mounted thereon. When the scaffold is mounted on a wall surface a second post member is releasibly mounted on the first post member and receives the guard rail support member instead of the first post member.

Abstract: A portable, collapsible brace for mounting scaffolding on the side of a building, comprises a generally "U"-shaped structure made up of two bent arms, each comprising an upright, surface-engaging section having an oblique section at its lower end. The upright sections are spaced from each other by a standard building wall stud spacing and can be nailed to the studs. The oblique sections are connected to each other at a point between the stud locations. An arm is pivotally connected to this point, and is removably engageable with a platform pivoted to the upright sections. The platform is also generally U-shaped, and nests inside the attachment arm structure in coplanar relationship therewith when the apparatus is collapsed.

The articulated parallelogram boom assembly includes a floating frame, a lower parallelogram boom assembly operationally connected between the superstructure frame support and the floating frame, an upper parallelogram boom assembly operationally connected between the floating frame and the riser, and a lift mechanism for raising and lowering the articulated parallelogram boom assembly. The lower parallelogram boom assembly, the upper parallelogram boom assembly, and the lift mechanism are formed such that the maximum extension height of the articulated parallelogram boom assembly is increased without an increase in the height of the articulated parallelogram boom assembly when lowered.

Abstract: A load-dispersing device for use with a ladder has a pail of flexible members having first and second configurations and a memory to return the members from the second to the first configuration. An interior cavity within each member is exposed, when each member is in the second configuration, through a longitudinal slit. Separating the longitudinal slit exposes the interior cavity placing the member in the second configuration for mounting on the respective ladder side rail and releasing the longitudinal slit returns the member to the first configuration and secures the member around the respective side rail. The member having contact and locking areas which can be manufactured either from separate material or integral with one another. The contact area can have an undulating surface and can have a spring embedded within the contact area to return the member to the first configuration. The contact area can alternatively be adhered directly to the load-bearing surface of the ladder.

The carrier includes a holster for gun shaped tools. An electric cord holder provided with or separately from the carrier holds an electric cord close to the working elevation of the platform. The electic cord holder includes a foldable strap having two portions which are matable when the strap is folded to form an opening smaller than the head of an electric cord to secure the electric cord between the two portions.

Abstract: An escape ladder stored in an interior wall of a building, beneath a window. The ladder is deployed by placement through a window with a storage container providing a step for ease in exiting. Ladder steps are secured by a flexible strap with each step including an integral spacer to maintain proper positioning of the steps upon deployment. The ladder is stored in a nest configuration pattern with the connecting strap folded between each step.

Abstract: A fold-up step ladder having individually and independently fold-down steps that are deep recessed in their fold-down position, so that a person standing on the ladder can lean into and between the ladder frame defined by front and rear side rails and reach closer, with less obstruction and likelihood of injury, to an adjacent vertical wall or work object. Each step is supported upon the side rails of the ladder by an extension arm and a pair of right-angle flanges attached to respective side rails of the ladder frame. The flange bracing allows for support of over-sized steps, which in turn provides the standing person with a greater support and sure-footed feeling, as well as reduced fatigue upon the ladder.

Abstract: An accessory device capable of being mounted on a ladder having hollow rungs includes a pair of primary support arms which are shaped to fit within rungs having flat top sides to prevent rotation of the primary arms therein. Secondary support arms are slidably extensible from the primary support arms to laterally position a tray assembly relative to one side of the ladder. A brace connected to the secondary support arms engages a tray assembly. The level of the tray relative to the slope of the ladder is adjusted by varying the position of arcuate slots found within a pair of flanges mounted on the bottom side of the tray relative to the brace. Thus, a user can adjust the level of the tray while keeping one or both hands on the tray for stability. The device may be mounted to either side of the ladder with the supporting arms and brace optionally remaining mounted on the ladder during transport and/or storage.
