Abstract
A scroll-type display sign is provided, including a frame, a first fixed shaft connected on the frame, a second fixed shaft connected on the frame parallel spaced from the first shaft, a first scroll roller rotatably mounted on the first shaft, a second scroll roller rotatably mounted on the second shaft, a signage web connected on the first and second scroll rollers, a drive sprocket affixed with the first scroll roller and mounted on the first shaft, a spring sprocket affixed with the second scroll roller and mounted on the second shaft, a constant force spring connected with the spring sprocket to tension the signage web, and a motor torsionally connected with said drive sprocket.
Claims17
A scroll-type display sign comprising:
- a frame;
- a first fixed shaft connected on said frame;
- a second fixed shaft connected on said frame parallel spaced from said first shaft;
- a first scroll roller rotatably mounted on said first shaft;
- a second scroll roller rotatably mounted on said second shaft;
- a signage web connected on said first and second scroll rollers;
- a drive sprocket torsionally affixed with said first scroll roller and rotatably mounted on said first shaft;
- a spring sprocket torsionally affixed with said second scroll roller and rotatably mounted on said second shaft;
- a constant force spring connected with said spring sprocket by a first flexible force transmission member to tension said signage web;
- and
- a motor torsionally connected with said drive sprocket by a second flexible force transmission member to turn said signage web.
A scroll-type display sign comprising:
- a frame having at least first and second spaced apart ends;
- a first fixed shaft with extreme ends fixably connected with said frame ends;
- a second fixed shaft with extreme ends fixably connected with said frame ends parallel spaced from said first fixed shaft;
- a first scroll roller rotatably mounted on said first shaft;
- a second scroll roller rotatably mounted on said second shaft;
- a signage web connected on said first and second scroll rollers;
- a drive sprocket torsionally affixed with said first scroll roller and rotatably mounted on said first shaft;
- a spring sprocket torsionally affixed with said second scroll roller and rotatably mounted on said second shaft;
- a constant force spring connected to said spring sprocket by a first flexible force transmission member to tension said signage web;
- and
- a motor torsionally connected with a pulley via a gear box, said pulley engaging a toothed belt to turn said drive sprocket to move said signage web and wherein said gear box mounts said pulley and said spring.
A scroll-type display sign comprising:
- a frame including two spaced-apart ends;
- a first fixed shaft connected along extreme ends with said frame ends by pop-in saddles mounted in said frame ends;
- a second fixed shaft with extreme ends connected with said frame ends by pop-in saddles mounted in said frame ends parallel spaced from said first fixed shaft;
- and
- at least first and second signage modules, each said signage module including:
- a first scroll roller rotatably mounted on said first shaft;
- a second scroll roller rotatably mounted on said second shaft;
- a signage web connected on said first and second scroll rollers;
- a drive sprocket torsionally affixed with said first scroll roller and rotatably mounted on said first shaft;
- a spring sprocket torsionally affixed with said second scroll roller and rotatably mounted on said second shaft;
- a constant force coil spring being connected to said spring sprocket by a first flexible force transmission member to tension said signage web;
- and
- a motor connected with said drive sprocket by a second flexible force transmission member for turning said drive sprocket to move said signage web.
