Abstract: Display devices such as scoreboards having reversible display surfaces are mounted to support frames using opposing clamps each having a pivot post extending therefrom. The clamps engage one of the boards or frames with the posts being seated in openings in the other of the boards or frames. One or more latches extend between the support frames and boards to prevent rotation of the boards when in a locked position.

Abstract: A portable visual display assembly comprises modular sections selectively configurable between a combined full-size display board configuration and a separated plural smaller single display board configuration. The display boards can have identical or different grids permanently displayed on their front and back faces. The assembly includes wheels which are removable in both configurations. The display boards can be propped open to a selected angle. The visual display assembly is particularly suitable for use as a scoreboard for sporting event tournament play, such as for golf events, with the full-size configuration being advantageous for tournaments having a large number of participants.
