ABSTRACT:
A collapsible swing-out extendible music stand capable of tilting and holding multiple sheets or books simultaneously on a vertical shaft and foldable tripod base. The upper section is a backrest consisting of plates connected by vertical hinges attached to folding shelf segments by horizontal hinges. The outermost plates may be used individually or in tandem being secured to the back of the primary plates by fastening devices, when not in use. A handle is mounted on the front of the center plate for carrying. A pivot device on the reverse side allows tilting of the backrest. A vertical shaft within a shaft and tensioning device permits height adjustment. In the second embodiment the outermost plates fold opposite toward the front, and are without attached shelves. The additional shelf panels are hinged to and folded beneath the main shelves, secured by fastening devices. When in use, the shelf panels are attached by locking device to the extended outermost plate.
