发明名称 Dual rotatable book holder
摘要 A dual rotatable book holder designed to hold two books for quick and easy reference. Two plates form a two face book platform with lips extending outwardly hold two books back-to-back. The two face book platform is removably engaged with a rotatable base allowing the user to quickly and efficiently rotate the two face book platform. The rotatable base comprises an upper section and a lower section which snap-fit together. The fitted upper section and lower section form a circular enclosure which encases one or more sets of ball bearings allowing the upper section to rotate freely upon the stationary lower section. The ball bearings are held in place by slots incorporated within a channel of the upper section and a groove in the lower section. A pin and tubular section arrangement connect the two plates and hinges connect the lips to the two plates allowing the two surface book platform to be folded into a flat piece when removed from the base for easy storage along with the flat base.
