Description

[Detailed Description of the Invention] The present invention relates to an evacuation rope suitable for evacuation from the fourth floor, third floor, second floor, etc. to the ground.

This type of rope that has been used in the past is usually made of nylon, and when you actually use it and hang from it, all your weight is added to your hands, making it impossible to hold the rope and causing you to slip. Due to the friction, an accident occurred where he let go of the rope and fell.

Therefore, there are ropes that have knobs at appropriate intervals to prevent the hands from slipping.

Although this can solve the problem of slippage mentioned above,
The spacing between the bumps does not match all evacuees; in other words, the spacing between the bumps is approximately determined depending on the height of the evacuee, so the spacing between the bumps must be made very short.

However, if the spacing between the bumps is shortened, a longer length of rope must be used, which has the disadvantage that the rope becomes bulky and expensive when stored.

The present invention focuses on the above-mentioned points, and aims to provide an evacuation rope that does not become bulky when stored, stretches during use, and does not slip from the hands.

An embodiment of the present invention will be described below with reference to the drawings.

1. Use metal hooks to hang on the balcony handrails, etc.
All metal fittings used for mountain climbing etc. can be applied.

2 is a string loosely (coarsely woven) in a cylindrical shape 2a using a large number of thick threads made of a suitable durable material such as nylon.

Reference numeral 3 denotes a rubber string which is inserted into a bundle into the cylindrical shape 2a of the string 2, and whose upper and lower ends are fixed to the upper and lower ends of the edge 2, respectively.

The upper end of the string 2 through which the rubber string 3 is inserted is inserted into the ring 1a of the metal fitting 1 and tied, and is fixed by caulking with a retaining ring 4.

Further, the lower end of the string 2 is tied together with the rubber string 3.

As a result, the elastic string 3 is fixed to both ends of the string 2, so that the string 2 is shortened and shortened by the contraction force of the elastic string 3.

When using the rope of the present invention during an evacuation or the like, the rope is hung by hooking the metal fitting 1 onto a handrail or the like.

The evacuee then grabs the part of the rope that is easy to grip and descends, but when the person hangs the rope, the hook is attached to metal fitting 1.
Since the rubber string 3 is stretched at the part and the string 2 is also loosely woven, the length of the rope increases as the person moves downward.

Therefore, even if the rope in storage is short, it can essentially be used as a long rope.

Also, when descending, the part above the part held by the hand stretches and the outside diameter of the string 2 becomes thinner, but the part below the part held by the hand is contracted by the rubber string 3, so the outside diameter of the string 2 becomes thicker. There is.

Therefore, the same effect as the conventional bump can be obtained, and the hand will not slip.

Therefore, it can be descended safely. As mentioned above, the present invention integrates a rubber cord into a stretchable cord, so that it is always short with the rubber cord, making it convenient for storage, and in case of evacuation, etc. The hook attached to one end is used to hang the metal fitting onto a balcony railing, etc., and when you hold this rope in your hand and hang it, the upper part of the rope you hold in your hand stretches and becomes thinner in diameter, while the lower part of your hand becomes thicker. This has the effect of preventing your hands from slipping and allowing you to descend safely.
