Patent ID: 7895781

Claim:
A device having a system of movable slats configured and arranged for visual display of a plurality of numbers, wherein each of the numbers is associated with a down in a football game, the device comprising: a housing having first and second sides, wherein the first and second sides each has a generally rigid frame and a transparent display window, wherein the first and second sides are configured to cooperatively provide an enclosed interior, and wherein the frame has at least three pivot pin receptacles fixedly secured thereto, and further wherein the frame has a plurality of support leg receiving members fixedly secured thereto; a non-movable support located in the enclosed interior and comprising a plurality of support legs configured and arranged for coupling with the support leg receiving members, wherein the non-movable support is mounted on the frame and substantially stabilized against movement relative to the frame when the support legs are coupled with the support leg receiving members; a non-movable set of slats attached to the non-movable support and configured to cooperatively display a number associated with a fourth down in a football game; three movable supports located in the enclosed interior, wherein each movable support is slidably attached to the non-movable support and configured and arranged to be moved between a first position and a second position; three movable sets of slats, wherein each set is attached to a respective movable support, wherein each set comprises a plurality of slats, configured to cooperatively display a number associated with a first down, a second down or third down in a football game, and wherein the number is selectively displayable through the transparent window when the associated movable support is in the first position and the number is not displayed when the movable support is in the second position; three arms, wherein each arm has an exterior portion and an interior portion, wherein the arm exterior portion of the arm is configured to extend out of the housing, such that the arm exterior portion is accessible to a user, wherein each arm interior portion includes a pivot pin configured to be received in and rotatably engaged by a pivot pin receptacle so as to secure each arm to the frame but also so as to allow pivotal movement of each arm relative to the frame, and wherein the arm interior portion is movably coupled to a respective movable support, whereby movement of the arm exterior portion to a first position cooperatively moves the movable support to the first position, and movement of the arm exterior portion to a second position cooperatively moves the movable support to the second position, whereby the user is allowed to select to display any one of the four numbers associated with the downs of the football game and whereby both the arms and the non moveable support structure are secured to the frame to prevent substantial movement of the non moveable support structure relative to the frame even when the frame is jolted.
