Abstract: A mounting and lowering system for supporting one or more luminaires or similar devices having use within an indoor space or similarly configured space such as an open-air pavilion or the like, the system comprising a support assembly capable of being raised and lowered above a location within such a space not conveniently available for use in the servicing of luminaires or devices mounted by the system. The present system includes a latching mechanism permitting remote latching and unlatching of the support assembly. Vertical displacement of the support assembly can be effected without power interruption. Primary drive components are positioned within the system to facilitate service and replacement. The invention further contemplates transition apparatus capable of use in indoor spaces having differing ceiling angles.

Abstract: A support assembly capable of being raised and lowered on a mast and configured in a compact, volumetrically efficient conformation lending architectural significance to the appearance of the support assembly when used to mount a plurality of luminaires or other apparatus intended for use in a location above a surface, such as the surface of the earth, the invention permits remote latching and unlatching of the support assembly through use of an improved latching mechanism having dimensions permitting housing of the latching mechanism within an enclosure of a reduced height, thereby lending an esthetically pleasing appearance to a mast-mounted support arrangement relative to prior art assemblies intended to perform similar functions.
