ABSTRACT:
A rotary tilt base for a video terminal which enables the operator using the terminal to rotate and tilt respectively, a portion of the base so as to orient the terminal to provide greatest comfort and greatest ease of operation. The base basically includes an upper member and a lower member with the upper member being both rotatably and pivotably mounted to the lower member. In that regard, a convex portion of the upper member slides and rotates within a concave portion of the lower member. The tilting action of the upper member is restricted by guide means which include an elongated linear slot passing completely through the upper member. The guide means insures that the tilting action occurs only in a single, namely, front to back direction. The upper member is secured to the lower member by a generally U-shaped bracket which is positioned to abut or be closely adjacent a portion of the guide means. The bracket serves to position a connecting bolt centrally within the width of the elongated slot, thus permitting the bolt to readily rotate and move longitudinally within the slot to effectuate the rotational and tilting action, respectively, as desired.
