Abstract: A temporary platform for assembling elevator equipment in an elevator shaft is arranged substantially in the region of a shaft opening, such that the platform partially sits on a floor surface of the building and partially protrudes into the elevator shaft. The platform includes a bottom frame and bottom plates that lie on or are inserted into the bottom frame. The bottom frame also includes two lateral bottom bars, at least one front and one rear transverse bar that interconnect the two lateral bottom bars, and at least two intermediate bars that are arranged parallel to the two lateral bottom bars. The two intermediate bars are supported substantially by the front and the rear transverse bars.

Abstract: An air conditioning mounting bracket assembly is a fully adjustable bracket assembly designed to be installed on the exterior of a window or thru wall air conditioner, manufactured of heavy duty steel and plastic Plexi-material for strength and durability. Sheeting material will encompass the entire exterior of the A/C unit, with grating integrated into the support plates to allow free circulation of air. Screws and hook and loop material will be included for use in mounting the assembly to the exterior of the window frame, and heavy duty threaded bolts are included to mount the A/C unit to the mounting assembly. Telescoping components enable the user to lengthen or shorten the assembly in accordance to the dimensions of the window frame or wall niche.

Abstract: An improvement in portable scaffold assemblies which enables a scaffold to be securely hung upon a vertical portion of the building, without the need for permanent anchoring means, either on the building or on the scaffolding frame itself. The portable scaffold assembly is preferably constructed of square tubing, with a main pair of open-ended vertically extending tubular members comprising the main structural member for a permanent walkway, and also for hanging an auxillary walkway, therebelow. The scaffold may be positioned, in a vertical sense, very close to the top of the vertical building portion which supports the assembly, or telescoped downwardly therefrom to any desired extent. This is allowed by a pair of L-shaped upper arms which telescopically engage both the main scaffold holder assembly, and also the removable L-shaped anchors, which are movably fitted against the vertical supports of the building structure.
