DE19511117A1 - Automatic abseiling descent equipment - Google Patents

Abstract

The length of the rope is fixed by the user. The length required depends on the building or height descended. The automatic payout locking device has a weight brake depending on the weight of the person or material. It also has a centrifugal brake (5) used as an extra preventative measure against exceeding the maximum allowed payout speed.

Description

It is an automatic descender for abseiling people, goods and loads from buildings. Due to a centrifugal brake, the running speed will be lower than the falling speed in order to avoid damage (see Fig. 3). This affects personal injury (sprains, breaks, etc.) First, the wire rope is either attached to an installed abseiling device (A) ( Fig. 2 and 3) and the rope is lowered with a counterweight of approx. 2 kg to a certain tension of the rope to achieve and to enable the first person to abseil. This first person can either hold the end of the rope or fix it at a possible stopping point (parking sign, car tow hook, tree, etc.). If someone does not have this abseiling device (for reasons of cost, the rope can be attached to the window cross, apartment door, central heating or, for this purpose, a cemented hook on the wall ( Fig. 2 (K)). This abseiling device can also be taken independently to Example when I go on vacation, I just have to know beforehand how long it will take me a steel rope to get over the height of the quarters in the hotel The invention of this rappelling device is relatively cheap and can vary from one use to multiple use of one up to several people and used for loads. For offices, hotels or high-rise buildings and similar buildings that exceed a certain height that cannot be reached by a fire brigade ladder. This can be determined as a fixed mandatory security system. For the rescue of people or guests at risk of fire Hotels, high-rise buildings, etc. were partly permanently installed Fire escapes used often had the disadvantage that the smoke development was so strong over corridors, corridors or stairwells that they could not be reached. For such facilities, the abseiling device with belt must be visible in every room according to the number of beds, so that guests and visitors can take their rescue equipment with them and can also abseil from another room, where e.g. B. a lifeline has already been unhooked. Many people were rescued by helicopters at the last second or jumped to certain death out of despair and panic. For hotels or public buildings, offices or high-rise buildings, a rappel device can be attached to each room to make it easier for people to hang and rappel safely (see Fig. 3).

Due to the weight-dependent abseil brake you can e.g. B. 20 kg to 150 kg abseiling safely and even attaching and draining even unconscious people, since the expiration speed is reasonable and unrolls independently ( Fig. 1 and 1/1).

To date, there is no comparable rescue device on the market. All similar devices must be drained and the rescue rope pulled up again to carry one more person at a time. For offices, business premises, hospitals, etc., a fire-proof container can also be attached, in which small children, infants, important business documents, valuables, diskettes, people, etc. (see Fig. 3, Fig. 2B, AS and S).

The descender consists of the following parts:

• 1. Descender with eyelet and joint ( Fig. 2A)
• 2. Wire rope with snap hook and weight ( Fig. 2D)
• 3. Seat belt with snap hook ( Fig. 2K and S)
• 4. Fire-proof container with snap hook ( Fig. 2B)
• 5. Automatic descender ( Fig. 1/1 and Fig. 2)

The handling of the descender is as follows.

In the event of danger, the abseiling device attached to the window is either unfolded ( Fig. 3) or with a loaded container (valuables, goods or small children) ( Fig. 3) then together with the automatic abseiling using the snap hook ( Fig. 2K) and rope let out the window. The automatic descender is attached to the wire rope ( Fig. 1/1) and secured with a safety bracket.

The rappelling is done automatically at a reasonable speed and can used by the following people or goods on the one-time attached rope will. If there are more people to be evacuated than there are automatic descenders, they can the already descended automatic descenders all together on the hanging one again The wire rope can be pulled up again and the abseiling can be continued as desired. The automatic descender is equipped as follows.

It consists of 2 gears, 2 guide rollers and a centrifugal brake, which is equipped with a brake lever with eyelet ( Fig. 1). The brake lever acts with the weight of the person or that of the container on the brake drum, which increases with the running speed and thus prevents a too rapid downward movement.

Claims (4)

1. The automatic descender is for height differences up to 200 meters, characterized in that the length of the rope is determined by the consumer (user) himself, according to the building or the height to be overcome. 2. The self-run safeguard is not only in accordance with the weight brake Weight, the expiring goods or the person marked, but still additionally equipped with a centrifugal brake to prevent the flow from being exceeded to secure the speed additionally. 3. The automatic descender is secured in such a way that it can be rappelled without outside help can. 4. But it is also suitable for discharging foreign people or goods, such as e.g. B. injured persons, small children etc.
