Abstract

The present invention is directed to an embedded interconnecting drive system. The drive system is used to deploy and retract flexible, roll-up panels away from or onto a roller drum as the drum rotates on its longitudinal axis. In this invention, a plurality of cogs, each comprising a semi-tubular recess and tapered shaft, interact with each other to induce the flexible panel to move in concert with the roller drum as the roller drum rotates, preventing the flexible panel from unraveling on the drum. The cogs compel the flexible panel to deploy away and downward from the drum as it rotates deployingly, and to retract onto the roller drum as it rotates retractingly. This invention discloses details of the cog and a complimentary annular lock disc used to secure the cog to a flexible panel. Further, this invention discloses a plurality of embodiments of the embedded interconnecting drive system.

First claim

The invention claimed is:

1. An embedded interconnecting drive system to deploy and retract a flexible, roll-up panel comprising:
a roller drum;
a flexible panel joined to the roller drum;
the flexible panel having a first side, a second side, a first surface, and a second surface;
a winding mechanism attached to the roller drum;
a plurality of cogs;
a plurality of annular lock discs; the cogs and annular lock discs disposed intermittently latitudinally along the first side and the second side of the flexible panel;
the cogs disposed through the flexible panel and the annular lock discs disposed complimentarily around the cogs adjacent the second surface; wherein,
the plurality of cogs interconnecting when the flexible panel is wound around the roller drum; and wherein
the plurality of cogs imposing a deploying force on the panel as the panel is unwound and a retracting force on the panel as the panel is wound around the drum.

2. The embedded interconnecting drive system of claim 1 wherein the roller drum comprises material which is selected from the group consisting of hollow core cylinders and solid core cylinders.

3. The embedded interconnecting drive system of claim 1 wherein the roller drum further comprises countersunk recesses disposed around opposite ends of the roller drum.

4. The embedded interconnecting drive system of claim 3 wherein the plurality of cogs disposed on the first and second sides of the flexible panel interconnect with the countersunk recesses disposed on the opposite ends of the roller drum.

5. The embedded interconnecting drive system of claim 1 wherein the roller drum further comprises material which is selected from the group consisting of polyvinyl chloride, carbon fiber, wood, engineered wood, nylon, rubber, and plastic.

6. The embedded interconnecting drive system of claim 1 wherein the roller drum further comprises metal which is selected from the group consisting of steel, stainless steel, aluminum, brass, and titanium.

7. The embedded interconnecting drive system of claim 1 where in the flexible panel is joined to the roller drum by means of chemical and mechanical attachments.

8. The embedded interconnecting drive system of claim 1 wherein the flexible panel comprises materials selected from the group consisting of window screen, sun screen, vinyl, plastic, mass-loaded vinyl, cloth, leather, video screen, organic light-emitting diode panels, and solar panels.

9. The embedded interconnecting drive system of claim 1 wherein the winding mechanism turns the roller drum on its longitudinal axis to raise and lower the flexible panel.

10. The embedded interconnecting drive system of claim 1 wherein the winding mechanism comprises devices which are selected from the group consisting of manual and motor-driven apparatuses.

11. The embedded interconnecting drive system of claim 1 wherein each of the cogs comprises a head, a semi-tubular recess, and a tapered shaft.

12. The embedded interconnecting drive system of claim 11 wherein the head comprises a concave first surface and a convex second surface, the concave first surface continuing to the semi-tubular recess, and the semi-tubular recess extending into the tapered shaft.

13. The embedded interconnecting drive system of claim 12 wherein each of the cogs further comprises a sheath extending from the convex surface of the head and comprising a hollow cylinder disposed around the tapered shaft.

14. The embedded interconnecting drive system of claim 1 wherein the plurality of cogs comprise metals selected from the group consisting of stainless steel, steel, aluminum, titanium, Monel, and brass.

15. The embedded interconnecting drive system of claim 1 wherein the plurality of cogs comprise material selected from the group consisting of plastic, nylon, carbon fiber, polyoxymethylene, and polyvinyl chloride.

16. The embedded interconnecting drive system of claim 1 wherein the annular lock discs comprise a concave first surface and a convex second surface.

17. The embedded interconnecting drive system of claim 1 wherein the plurality of annular lock discs disposed around the plurality of cogs are secured in place by means of the sheaths flattened over the convex surfaces of the plurality of annular lock discs.

18. The embedded interconnecting drive system of claim 1 wherein the plurality of annular lock discs comprise metals selected from the group consisting of stainless steel, steel, aluminum, titanium, Monel, and brass.

19. The embedded interconnecting drive system of claim 1 wherein the plurality of annular lock discs comprise material selected from the group consisting of plastic, nylon, carbon fiber, polyoxymethylene, and polyvinyl chloride.
