Unfurlable rescue ladder
View Patent ↗An unfurlable rescue ladder. The ladder includes a progress capture element allowing someone who deploys the ladder for rescuing a person who has fallen to also assist the person to climb the ladder.
1. An unfurlable rescue ladder for climbing by a climber, comprising:
a hanger element having a connecting aperture therethrough that is either “closed” or “closeable”;
a first connecting element having a connecting aperture therethrough that is either “closed” or “closeable”;
a rope;
a progress capture element having a connecting aperture therethrough, and a separate rope-passing aperture therethrough for passing the rope through the progress capture element, the connecting and rope-passing apertures being either “closed” or “closeable,” the progress capture element for capturing the climber's climbing progress and therefore allowing for climbing up the rescue ladder but not for climbing down the rescue ladder; and
either a plurality of rung elements attached to each other in sequence so as to form a chain of rung elements with a first end of the chain depending from the hanger element, or a plurality of rung elements attached to and between spaced apart rail elements in sequence with respective first ends of the rail elements depending from the hanger element, wherein the hanger element is connected to the first connecting element such that a portion of the hanger element that surrounds the connecting aperture through the hanger element passes through the connecting aperture through the first connecting element, and a portion of the first connecting element that surrounds the connecting aperture through the first connecting element passes through the connecting aperture through the hanger element, and wherein the first connecting element is connected to the progress capture element such that a portion of the connecting element that surrounds the connecting aperture through the connecting element passes through the connecting aperture through the progress capture element, and a portion of the progress capture element that surrounds the connecting aperture through the progress capture element passes through the connecting aperture through the first connecting element.
2. The ladder of claim 1 , wherein the progress capture element includes a progress capture pulley.
3. The ladder of claim 2 , wherein the first connecting element includes a carabiner.
4. The ladder of claim 1 , wherein the first connecting element includes a carabiner.
5. The ladder of claim 4 , further comprising a second connecting element having a first connecting aperture therethrough, the first connecting aperture through the second connecting element being either “closed” or “closeable,” wherein the second connecting element is connected to the hanger element such that a portion of the hanger element that surrounds the connecting aperture through the hanger element passes through the first connecting aperture through the second connecting element, and a portion of the second connecting element that surrounds the first connecting aperture through the first connecting element passes through the connecting aperture through the hanger element.
6. The ladder of claim 5 , further comprising a third connecting element having a connecting aperture therethrough, the connecting aperture through the third connecting element being either “closed” or “closeable,” wherein the second connecting element has a second connecting aperture, the second connecting aperture through the second connecting element being either “closed” or “closeable,” wherein the second connecting element is connected to third connecting element such that a portion of the second connecting element that surrounds the second connecting aperture through the second connecting element passes through the connecting aperture through the third connecting element, and a portion of the third connecting element that surrounds the connecting aperture through the third connecting element passes through the second connecting aperture through the second connecting element.
7. The ladder of claim 6 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a fourth connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the fourth connecting element, and wherein a portion of the fourth connecting element that surrounds the connecting aperture through the fourth connecting element passes through the connecting aperture through the end of the rope.
8. The ladder of claim 5 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a third connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the third connecting element, and wherein a portion of the third connecting element that surrounds the connecting aperture through the third connecting element passes through the connecting aperture through the end of the rope.
9. The ladder of claim 4 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a second connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the second connecting element, and wherein a portion of the second connecting element that surrounds the connecting aperture through the second connecting element passes through the connecting aperture through the end of the rope.
10. The ladder of claim 3 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a second connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the second connecting element, and wherein a portion of the second connecting element that surrounds the connecting aperture through the second connecting element passes through the connecting aperture through the end of the rope.
11. The ladder of claim 2 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a second connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the second connecting element, and wherein a portion of the second connecting element that surrounds the connecting aperture through the second connecting element passes through the connecting aperture through the end of the rope.
12. The ladder of claim 1 , wherein an end of the rope has a connecting aperture therethrough which is “closed,” further comprising a second connecting element having a connecting aperture therethrough which is “closeable,” wherein a portion of the end of the rope that surrounds the connecting aperture through the rope passes through the connecting aperture of the second connecting element, and wherein a portion of the second connecting element that surrounds the connecting aperture through the second connecting element passes through the connecting aperture through the end of the rope.
