Shaft for use with clamp device
A shaft for use with a clamp device, includes a cable which extends through a bore of the shaft; and a plurality of alternating first beads and second beads defining the shaft, each of the first and second beads having an inner opening defining the bore of the shaft, and having a surface, wherein each of the second beads has a larger inner diameter of the inner opening than each of the first beads, each of the second beads is supported on the surface of two adjacent first beads at a line of contact, and the surface of each of the second beads has a convex shape at the line of contact, wherein the first beads and the second beads have a three-dimensional convex torus configuration.
1. A shaft for use with a clamp device, comprising:
a cable which extends through a bore of the shaft; and
a plurality of alternating first beads and second beads defining the shaft, each of the first and second beads having an inner opening defining the bore of the shaft, and having a surface,
wherein each of the second beads has a larger inner diameter of the inner opening than each of the first beads, each of the second beads is supported on the surface of two adjacent first beads at a line of contact, and the surface of each of the second beads has a convex shape at the line of contact, wherein the first beads and the second beads have a three-dimensional convex torus configuration.
2. The shaft of claim 1 , wherein the surface of each of the first beads has a convex shape at the line of contact.
3. The shaft of claim 1 , wherein each of the second beads has a larger outer diameter than each of the first beads.
4. The shaft of claim 1 , wherein each of the second beads has a smaller outer diameter than each of the first beads.
5. The shaft of claim 1 , wherein each of the second beads has the same outer diameter as each of the first beads.
6. The shaft of claim 1 , wherein the line of contact is a circular line of contact.
7. The shaft of claim 1 , wherein the line of contact exists between the first beads and second beads at all times.
8. A shaft for use with a clamp device, comprising:
a cable which extends through a bore of the shaft; and
