Abstract
Using a carabiner for securing rock climbing rope, it is known that the rope can only be removed from the carabiner by human hand. In this invention, an electric rope removal system is secured to the carabiner which pulls a pulley string that is attached to a rotating disk which is attached to an axle on the carabiner and removes the rope from the carabiner when the electric rope removal system is on. The electric rope removal system is governed by a timer. Another safety feature is the overall power of the electric rope removal system which can be adjusted to not remove the rope when the weight of a mountaineer is attached to the rope that is attached to the carabiner.
Repel - sliding down a rock climbing rope with a metal locking device.
Carabiner - a piece of oval metal which holds a rock climbing rope into place with a movable safety gate to prevent the rope from leaving the carabiner.
Mountaineer - a person that climbs(ascends) and descends a mountain or rock face (also known as a rock climber) Rock Face - a large vertical cliff on the side of mountain or hill.

1. Field of the Invention The present invention relates to rock climbing equipment which is used by mountaineers to climb rock faces and mountains. An invention to remove rope from a carabiner.
2. Where the idea came from While watching the Mt. Everest Disaster on the news five years ago and reading Into Thin Air by Jon Krakauer, I was really upset by the amount of climbers that were killed. After having some experience in rock climbing I started to think about a fast way mountaineers could descend off of a mountain. Most mountaineers are killed when descending not ascending. This is due to fatigue and low oxygen at the end of a climb. One of the problems descending with rock climbing equipment is the need of using a double strand rope repel. A repel is descending down a rope. The double strand repel allows for rope retrieval. See figure 1 -5. The anchor is l, the rope is 2 and the mountaineer is 3. A
mountaineer can descend fizrther with a single strand repel (twice as far).
However, if a single strand repel is used, there is no way for the mountaineer to retrieve the rope. See figure 6. The double strand repel method has fizrther problems. The mountaineer has to set up quite a few anchors to descend due to the small length of the repel rope. See figure 7. If the mountaineer uses a long length double strand repel rope such as 300 metres, the mountaineer has twisting problems and rope retrieval is not possible and the 11 mm rope can be rather heavy. A 3 mm lighter double strand repel rope can not be use because it will twist as well. See figure 8. Therefore, a small repel rope is used and it can take a mountaineer up to 15 hours to descend off some alpine regions. See figure 7.
The 3Jl Electric Rope Removal System allows the rope to be released from anchor (the tree is this case). See figure 9 - 10. The mountaineer then has the repel rope and then can descend further. The 3JI Electric Rope Removal System gives the mountaineer an option of using a 600 metre 3 mm repel rope to descend quite quickly off the mountain (20 minutes) and use less anchor stations, 3 anchors for a 1800 metre descend. See Figure 11.
The maximum a mountaineer can descend using a double strand 50 metre repel rope is metres (a 50 metre descend rope may need up to 72 anchor stations to descend metres).
mountaineer can descend fizrther with a single strand repel (twice as far).
However, if a single strand repel is used, there is no way for the mountaineer to retrieve the rope. See figure 6. The double strand repel method has fizrther problems.

3. Summary of the Invention In one aspect, the present invention includes the combination of an electric pulley system, a case, and a rotating disk. The electric pulley system includes a light, switch, NCC solid state timer series A1M, electric motor, pulleys, pulley string, and string coil. The case is fiber glass/kevlar that surrounds the carabiner and components of the 3Jl Electric Rope Removal System. The rotating disk is a fiber glass/kevlar or aluminum shaped plate on a axle. The original carabiner, see figure 12, is composed of metal 1 with a gate 2 to prevent the rope out. The only way rope 3 can be taken in and out of a carabiner is by hand, see figure 13. The 3Jl Electric Rope Removal System takes the rope 32 out of the carabiner, see figure 16, a future look at the 3Jl Electric Rope Removal System. In figure 16, the pulley string 4 is mounted in the electric pulley system on the case 5. In figure 16, the electric pulley system rotates the rotating disk 6 which removes the rope 32 from the carabiner and the metal gate 2 from figure 13 on the carabiner is taken oil the carabiner in the 3Jl Electric Rope Removal System, as seen in figure 16. The carabiner used in the 3Jl Electric Rope Removal System is a Petzl Spirit carabiner manufactured by Petzl, a French rock climbing equipment company. The main purpose of this invention, 3Jl Electric Rope Removal System, is to take rope out of a carabiner.
The 3J1 Electric Rope Removal System SPECIFICATION
This invention relates to a rotating disk for removing rope from a carabiner using an electric pulley system.
The previous way of removing rope from a carabiner has been done by hand. The problems of removing rope from a carabiner by hand is if you repel (slide) down one strand of rope to get down a mountain, there is no way of retrieving your rope since it is attached to the top of the mountain 1. The difficulties of this is needing the rope once again since you only descended 50 metres and you have another, for example, 300 metres to descend, see figure 7. The anchor is 1, the rope is 2 and the mountaineer is 3. Taking more rope with you is an extremely heavy task. One way to use one small length rope to descend down a mountain in a double strand repel, as seen in figure 1 to 5.
Rope is multipurpose, that is it is used for ascending and descending. An ascend rope has to be 8.5 millimetres to 11 millimetres for safety reasons. It is possible to bring along a thin less weight descend 3 millimetre rope, however, there are problems with using a long double strand descend rope as seen in figure 8 which gets twisted and there is to much fi-iction to pull down one of the strands of the rope. Ascending or climbing with a 3 millimetres rope is dangerous too since it will not hold a fall if the mountaineer falls down the mountain since a fall has extremely more force than a repel. Therefore, the problem is getting your climbing rope unclipped from the top of a mountain when you are at the bottom of the vertical rope. These problems are also outlined in 'where the idea came from"
in the section, background of the invention.
I have found these disadvantages may be overcome by providing an electric pulley system and rotating disk to remove the rope out of the carabiner. Such electric pulley systems and rotating disks permit the removal of rock climbing rope from carabiner.
This adds electric power to a carabiner and makes the carabiner more usefizl thus adding safety to mountaineering. It will only be sold as an emergency item when one is stuck on the top of a rock face or when an anchor station is out of range. It will also be sold as a one time used item since a fall will damage the components and carabiner.
In one aspect, the present invention includes the combination of an electric pulley system, a case, and a rotating disk. The electric pulley system includes a light, switch, NCC solid state timer series A1M, electric motor, pulleys, pulley string, and string coil. The case is fiber glass/kevlar that surrounds the carabiner and components of the 3JI
Electric Rope Removal System. The rotating disk is a fiber glass/kevlar or aluminum shaped plate on a axle. The original carabiner, see figure 12, is composed of metal 1 with a gate 2 to prevent the rope out. The only way rope 3 can be taken in and out of a carabiner is by hand, see figure 13. The 3Jl Electric Rope Removal System takes the rope 32 out of the carabiner, see figure 16, a future look at the 3Jl Electric Rope Removal System. In figure 16, the pulley string 4 is mounted in the electric pulley system on the case 5. In figure 16, the electric pulley system rotates the rotating disk 6 which removes the rope 32 from the carabiner and the metal gate 2 from figure 13 on the carabiner is taken off the carabiner in the 3Jl Electric Rope Removal System, as seen in figure 16. The carabiner used in the 3Jl Electric Rope Removal System is a Petzl Spirit carabiner manufactured by Petzl, a French rock climbing equipment company. The main purpose of this invention, 3Jl Electric Rope Removal System, is to take rope out of a carabiner. In drawings which illustrate embodiments of the invention, figure 14 is a front view of the carabiner 1 with the carabiner hanging on a rope 31 with the carabiner's metal gate removed, see figure 13 metal gate 2. Figure 14 shows a fiber glass/ or kevlar mold 7 wrapped around the bottom end of the carabiner 1 but not molded onto the fiber glass or kevlar case 5 and the mold 7 has a metal axle holder 8 (see cross section figure 18 and mold 7). The metal bar 9 in figure 14 prevents the repel rope moving to the right and sliding off of the carabiner.
Figure 14 also shows the carabiner attached to the case at the top of the carabiner 10 and in the middle 11. Figure 14 also shows a view of metal bars molded into the case at number 12, number 13, number 14, which are all the same sizes. Also in figure 14 is a hole in the case for an electric motor 16. Figure 15 shows where the NCC solid state timer series A1M sits at 17 , 9 Volt battery, and battery holder are housed at 18. Figure 15 shows two wires 19, that go from the solid state timer 17 to the electric motor 16 and are inside the fiber glass or kevlar case, placed during molding. The figure 15 wires 20 lead from the battery up to the top case in figure 17 to an on/off switch 21.
Figure 17 also has wires 22 which leads from the on/off switch to the light 23 which has wires 24 going to the solid state timer 17 in figure 15. In figure 15 the rotating disk 6 is made out of fiber glass, kevlar, or aluminum and is .66 to actual size length and width and shape in figure 16 and is attached to a pulley string 4 which is attached to the pulley system and has a metal axle 25 molded into it as seen in figure 18 and the metal axle goes into the metal axle holder 8 in figure 18 and is 6 millimetres thick as seen in figure 18 (see cross section figure 18). Figure 15 shows the electric motor 16 which turns and pulls pulley string which coils above the electric motor as seen in figure 19 at point 26. At the top of figure 15 a pulley system is set up with a small metal donut looking rings (named ring for now on) at point 27 and point 28. As the electric motor gathers the pulley string inwards in figure 15, the pulley string is pulled down at ring 27 and ring 28. In figure 15 the pulley string is pulled upwards at point 13 and point 14 around the metal bars that were molded into the case in figure 14 at point 14 and point 13. Therefore, the pulley system contracts as seen in figure 16 thus pulling the rotating disk 6 and removing the repel rope 32. In figure 15 the metal ring 27 is attached to the pulley string that comes out of ring 28 by way of a figure eight knot (figure 8 is not a picture is a type of knot) and ring 28 is attached to the main rope 31 by way of a figure eight knot too at point 33. In figure 15 the main rope 31 is attached to the carabiner with a figure eight knot and anchored onto an anchor or tree with a figure eight knot. A pulley system may pull 10 centre metres of pulley string but the entire pulley system may only move 4 centimetres depending on the points where the rings are set up.
Actual circular pulleys are not need and rings have .6 the friction of a pulley circle. Figure 17 shows the final top case 34 placed onto the same carabiner 1 and bottom case 5 in figure 16. The case in figure 17 is sealed on the side 35 and side 36 with fiber glass or kevlar, however the top and bottom of the case is left open. The entire case prevents rock edges from pressing against the moving electric system inside of the case. The diagram at the bottom of figure 18 is a look from the bottom of figure 15 upwards into the bottom side of the 3Jl Electric Rope Removal System. Figure 18 shows the fiber glass or kevlar wrap on sides 35 and 36 keeping the whole unit together. The rotating disk 6 in figure 18 has a metal axle 25 molded into it with the metal axle going into the metal axle holder 8 which sits molded into the fiber glass or kevlar molding 7 that wraps around the carabiner 1. The cross section figure 18 also shows that there is space 37 and space 38 around the rotating disk and carabiner for rope placement. In figure 18 also shows the timer 17, battery holders 18, and metal bars 9 and 15. Cross section figure 19 is a view from the top of figure 15 downwards into the top side of 3Jl Electric. Rope Removal System, or looking down. In figure 19 you can see the electric motor 16 and the coil 26 above it.
The pulley string has be taken out not to get in the way. The top 34 and bottom 5 case in figure 19 is held together with a fiber glass or kevlar at 39 and 40. In figure 19 the metal bars 12, 13, and 14 are seen. Also on figure 19 are the fiber glass or kevlar moldings 41 and 42 that goes around the carabiner 1. Figure 20 shows block diagrams showing how the electric system is turned on. First the switch is turned on which turns on the battery which turns on the light which turns on the timer and before 30 minutes if the battery is turned offthe timer is reset and the electric system starts in the first block again. If 30 minutes has elapsed and the battery is still on, the timer allows output voltage and turns on the electric motor which starts the pulley system. If there is low weight on the repel rope, the pulley system with the rotating disk releases the repel rope from the 3Jl Electric Rope Removal System. If there is to much weight on the repel rope, the pulley system will not be able to use the rotating disk to release the repel rope. There is no automatic off switch or circuit breakers to avoid an electric fire, so the electric system will stay on but will not release the repel rope. This is set up to prevent the electric system from accidentally turning off.
