ABSTRACT:
A multiple section keyboard includes a universal support for each section permitting unrestricted orientation of each section. A vertical adjustable support includes a telescoping cylinder unit or a three point linkage support. A ball unit connects the vertical support to a slide unit for lateral placement. The ball unit provides rotational and pivotal positioning. A lock unit is coupled to the ball unit and simultaneously looks the ball unit, the linkage unit and the slide unit in place. A separable ball connector may also connect the top inner corners of two keyboards to maintain a V-shaped board configuration. Each section has a separate extendible spacer bar formed with a telescoping portion adapted to be extended outwardly and latched in place between angularly related and spaced keyboard sections. A separate number 6 key unit is provided for coupling to either section for inputting of the digit from that section. The multiple section keyboard desirably provides for some means for rapid location, placement and securement of the sections in particular locations. To this end, the single locking structure and support for each system contributes to the practical implementation of the new keyboard unit.
