Abstract

Claims (39)

1 . A rope ladder with a first braided rope, a second braided rope, and a plurality of ladder steps, comprising:

at least one first ladder step connecting element that is mounted to the first braided rope,

at least one second ladder step connecting element that is mounted to the second braided rope, and

at least one associated ladder step of the plurality of ladder steps that couples the at least one first ladder step connecting element with the at least one second ladder step connecting element;

wherein the at least one first ladder step connecting element is braided into the first braided rope and the at least one second ladder step connecting element is braided into the second braided rope, and

wherein the at least one associated ladder step of the plurality of ladder steps fixes the at least one first ladder step connecting element in the first braided rope and the at least one second ladder step connecting element in the second braided rope.

2 . The rope ladder of claim 1 wherein the at least one first ladder step connecting element is embodied as a first braiding member; and wherein the at least one second ladder step connecting element is embodied as a second braiding member.

3 . The rope ladder of claim 2 wherein each one of the first braiding member and the second braiding member comprises a ring-shaped body with an inner opening.

4 . The rope ladder of claim 3 wherein the inner opening exhibits at least a six-petalled Rosette shape.

5 . The rope ladder of claim 3 , wherein the inner opening is composed of a central opening with a predetermined number of radial extensions.

6 . The rope ladder of claim 5 wherein the radial extensions of the predetermined number of radial extensions are separated from each other by associated retaining fingers which extend from the ring-shaped body radially inward toward the central opening.

7 . The rope ladder of claim 6 wherein the associated retaining fingers comprise free ends which form bearing support surfaces that define a diameter of the central opening.

8 . The rope ladder of claim 7 wherein the diameter of the central opening corresponds to a diameter of the at least one associated ladder step of the plurality of ladder steps.

9 . The rope ladder of claim 5 wherein the first braided rope and the second braided rope are braided into the radial extensions of the predetermined number of radial extensions; and wherein the at least one associated ladder step of the plurality of ladder steps is mounted to the central opening such that the at least one associated ladder step blocks the first braided rope and the second braided rope in the radial extensions of the predetermined number of radial extensions.

10 . The rope ladder of claim 3 , wherein the ring-shaped body has a thickness of at least three centimeters.

11 . The rope ladder of claim 1 wherein the first braided rope comprises a first predetermined number of strands which are braided together to form the first braided rope, the at least one first ladder step connecting element being braided into the first predetermined number of strands; and wherein the second braided rope comprises a second predetermined number of strands which are braided together to form the second braided rope, the at least one second ladder step connecting element being braided into the second predetermined number of strands.

12 . The rope ladder of claim 11 wherein each one of the first braiding member and the second braiding member comprises a first plate-shaped surface and a second plate-shaped surface; wherein a first number of strands of the first predetermined number of strands is guided on the first braiding member from the first plate-shaped surface toward the second plate-shaped surface and back to the first plate-shaped surface, and a second number of strands of the first predetermined number of strands is guided on the first braiding member from the second plate-shaped surface toward the first plate-shaped surface and back to the second plate-shaped surface; and wherein a first number of strands of the second predetermined number of strands is guided on the second braiding member from the first plate-shaped surface toward the second plate-shaped surface and back to the first plate-shaped surface, and a second number of strands of the second predetermined number of strands is guided on the second braiding member from the second plate-shaped surface toward the first plate-shaped surface and back to the second plate-shaped surface.

13 . The rope ladder of claim 1 wherein each one of the first braided rope and the second braided rope comprises a first, a second, a third, and a fourth pair of strands that are braided together; wherein the at least one first ladder step connecting element is braided into the first, second, third, and fourth pair of strands of the first braided rope; and wherein the at least one second ladder step connecting element is braided into the first, second, third, and fourth pair of strands of the second braided rope.

14 . The rope ladder of claim 13 wherein each one of the first braiding member and the second braiding member comprises a first plate-shaped surface and a second plate-shaped surface; wherein the first and second pairs of strands of the first predetermined number of strands are guided on the first braiding member from the first plate-shaped surface toward the second plate-shaped surface and back to the first plate-shaped surface, and the third and fourth pairs of strands of the first predetermined number of strands are guided on the first braiding member from the second plate-shaped surface toward the first plate-shaped surface and back to the second plate-shaped surface; and wherein the third and fourth pairs of strands of the second predetermined number of strands are guided on the second braiding member from the first plate-shaped surface toward the second plate-shaped surface and back to the first plate-shaped surface, and the third and fourth pairs of strands of the second predetermined number of strands are guided on the second braiding member from the second plate-shaped surface toward the first plate-shaped surface and back to the second plate-shaped surface.

15 . The rope ladder of claim 1 wherein the first and second braided ropes have a length, wherein the lengths of the first and second braided ropes are at least partly provided with associated spacing and protecting elements, wherein the associated spacing and protecting elements preferably surround the first and second braided ropes.

16 . The rope ladder of claim 1 wherein each one of the first braided rope and the second braided rope are configured to widen respectively nondestructively at selected positions to allow insertion of the at least one first ladder step connecting element and the at least one second ladder step connecting element.

17 . The rope ladder of claim 1 wherein the at least one first ladder step connecting element and the at least one second ladder step connecting element are formed from a metallic material.

18 . The rope ladder of claim 1 wherein the at least one first ladder step connecting element and the at least one second ladder step connecting element further comprises a through-hole sized to receive a fastener consisting of one of two diameters, the larger of which is configured to form a bearing surface on which a head of a locking screw can rest.

19 . A rope ladder comprising:

a first braided rope;

a second braided rope spaced from the first braided rope; and

a plurality of ladder steps, at least one of the plurality of ladder steps comprising:

a first ladder step connecting element mounted to the first braided rope,
