Abstract
A climbing aid, for assisting a worker in climbing a ladder. A counter weight is provided, positioned through means of a rotating pulley assembly, a counter arrest system, and a cable system, in-part, help pull the climber up the ladder. The climber's weight is redistributed to allow the climbing aid to carry approximately 50% of the climber's original weight and will allow him to climb a ladder less strenuously. In this manner the climber must only exert the amount of effort required to carry the remaining 50 % of their weight. The redistribution of weight allows a climber to work for longer periods of time without tiring. The climbing aid is not an elevator but, rather, allows the climber to have full control of his ascent and descent at any and all times.
The climbing aid greatly reduces the strain on climbers and will result in a safer working environment for service people.
The climbing aid greatly reduces the strain on climbers and will result in a safer working environment for service people.
Description
CLIMBING AID
FIELD OF THE INVENTION
The present invention relates generally to safety climbing hardware, more specifically the present invention is a climbing aid to allow a worker to safely climb a ladder of great heights.
SUMMARY OF THE INVENTION
The present invention presents climbing hardware that will assist a climber to ascend and descend a ladder. While climbing a typical ladder, a climber must lift 100% of his or her weight. The present invention is a climbing aid that can redistribute the climber's weight so the climber must only carry 50% or less of his or her weight. This will make climbing less strenuous and less exertion ~y.'the climber will assist the climber in clear thinking and produce less fatigue for the climber. This makes the decisions and the climbing conditions considerably safer, especially when implemented on a long or tall ladder as on a windmill or sign.
Extremely tall ladders as on windmills can cause disorientation to the climber when fatigue sets in causing an unsafe work environment. The climbing aid reduces fatigue and creates a safer working environment for the climber.
As climbers exert themselves in climbing, their ability to make safe climbing decisions is reduced. When climbers connect themselves to structures at the top of the ladder and disconnect themselves from the safety climbing hardware, it is imperative that they do so in the proper order and with the clear thinking. This is particularly important when considering that some of the ladder rungs and platform decks are covered with grease and/or oil from leaking equipment and/or lubrication deposits at the top of the tower. Less exertion for high climbing results in clearer thinking and less fatigue, which makes the climber's decisions and conditions considerably safer.
Electric windmill generating farms are one example of the need for this climbing aid. The height of windmill towers used in the production of electricity exceeds 230 feet and service technicians climb these towers many times a day.
Even greater powered windmills are being designed to exceed 300 feet. Though the concept was initially designed to support the windmill industry need, the product is not limited to windmill towers. This lift aid can be used in any configuration where a climber has to ascend one continuous length of ladder.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT(s) The present invention is a climbing aid for helping a person to climb a ladder (10). A counter weight (80) positioned through means of a rotating pulley assembly (20), a run away safety lock system (69), and a cable system (30), in-part, help pull the climber up the ladder (10). The climber's (70) weight is redistributed to allow the climbing aid to carry approximately 50% of the climber's (70) original weight and will allow him to climb a ladder (10) less strenuously. In this manner the climber (70) must only exert the amount of effort required to carry the remaining 50 % of their weight. The lifting aid's percentages could very if the climbers weight was significantly different than and average climber's weight, X00 lbs (includes gear). The redistribution of weight provides for a safer working environment, and allows a climber (70) to work for longer periods of time without tiring, or to be more efficient in the same amount of time that they normally work. The climbing aid is not an elevator but, rather, allows the climber (70) to have full control of his or her ascent and descent at any and all times. The present invention greatly reduces the strain on climbers (70) and will result in a safer working environment for service people.
Figure 1 shows an isometric view of the present invention. For the purpose of representing the present invention, the climbing aid is portrayed below a tower internal platform (60), and inside the windmill tower (65). In addition, for the purpose of representing how the climbing aid is utilized, a climber (70), wearing a full body harness (75) is schematically portrayed. Neither the internal platform (60), windmill tower (65), the climber (70) nor the body harness (75) are part of the present invention.
In order for the climber (70) to use the climbing aid he or she should first put on the body harness (75). The climber (70) should then attach the safety glide (40) to the front of the body harness (75). The climber (70) should then attach the safety glide (40) to the fall prevention cable (67) at the bottom of the ladder (10).
Neither the safety glide (40) nor the fall prevention system is a part of the present invention. The climber (70) should then attach the body harness (75) to the climbing aid's two overhead cables (50). The climber (70) should then move to a squatting position and disconnect the climbing aid's attachment cable (85) from a low rung of the ladder (10). The climber (70) should then ascend the ladder (10) to the top. The relay of the climbing aid's cable (30) is described in detail below.
At this point, the climber (70) should detach the body harness (75) from the climbing aid's two overhead cables (50). The climber should then attach the safety lanyard (conventional to the body harness, not shown) to an overhead ladder rung, and disconnect the safety glide (40).
The climbing aid's relay cable (30) attaches the climber (70) to the counter weight (80). The cable (30) passes through a run-away safety lock (69) and through pulleys (20) to a passageway that allows the counterweight (80) to travel vertically. The climber (70), as ascending or descending the ladder (10), is assisted by the counterweight (80) system. In other embodiments of the present invention, the pulley system (20) will position the counterweight (80) around any and all obstacles adjacent to the ladder (10). The pulley (20) and counterweight (80) system allow the climber (70) to ascend or descend the ladder (10) without the increased fatigue produced by conventional systems.
The present invention is not limited to the sole embodiments above.
