Claims7
A sign comprising:
- a slat;
- and at least two double row roller chains;
- where said slat has a mid-section, two ends and two elbows;
- where said slat mid-section has at least two edges, each with a grooved opening for receiving a flexible sheet or strip;
- where each of said slat ends is shaped to removably engage at least a first roller in each of said roller chains;
- where a second roller of each chain is axially adjacent to said first roller, and is available to be engaged by a sprocket;
- and where each slat elbow is positioned between each of said slat ends and said slat mid-section, and each of said elbows curves forward from the mid-section a predetermined distance to meet said ends, and said elbows locate said slat mid-section along an extended imaginary axis of said engaged roller chain rollers when said slat ends engage said rollers.
A sign comprising at least first and second spaced apart double row roller chains and a slat including a slat mid-section and two opposed ends, the slat mid-section including at least two edges, each edge having a grooved opening for receiving a flexible sheet or strip and the grooved openings of the edges being opposite facing, each slat end being configured to removably engage at least one roller in a said roller chain and the slat being engaged at its ends to at least a first roller of the first roller chain and the second roller chain, respectively, a second roller of said first and said second roller chains axially adjacent to said first rollers being available to be engaged by a sprocket, said slat further including an elbow positioned between each slat end and the slat mid-section, each elbow being curved forwardly from the slat mid-section a predetermined distance to meet said ends, such that the elbows locate the slat mid-section along an extended imaginary axis of said engaged first rollers on said first and second roller chains.
