A linear drive mechanism includes first and second tapes formed of resilient material that each have an inner surface, a parallel outer surface, a first end, a second end and a concave/convex cross-section. A first tape guide has first and second guide slots that are sized and shaped to fit slidably about the first and second tapes and located to position the outer surfaces of the tapes adjacent one another. At least one second tape guide has third and fourth guide slots that are sized and shaped to fit slidably about the tapes. The tapes are connected together adjacent their first ends. A drive system has a mounting for the first tape guide that locates it orthogonal to lengths of the tapes. The drive system has rolled storage for the tapes and driving members for extending and retracting the tapes through the first and at least one second tape guide. |
