Abstract

The invention relates to mountaineering equipment and improves safety during descents on routes of varying difficulty. The device comprises a washer 1 with an oblong hole 2 for inserting the loop 3 of the rope. To the washer attached to the housing 4 in the form of a bracket. Two pairs of holes 5 and 6 are made on the sides of the bracket to accommodate the carbine 7. Both pairs of holes are offset from the axis 00 of the hole of the washer. Holes 6 are oblong and inclined to the end face 8 of the washer. Place the carabiner covering the rope in one of the pairs of holes 5 or 6. The speed of descent is different. Holes 5 are for downhill, and 6 are for more difficult stone-dangerous routes. 1 hp f-ly, 2 ill.

The invention relates to the equipment of climbers and installers and can be used in mountaineering, construction, fire fighting.

The purpose of the invention is to increase safety during descents on various routes of difficulty.

On fi | -. 1 shows a safety device; in fig. 2 - the same. side view.

The device contains a P1aibu 1 with an elongated hole 2 for razmelaeni net-3 ropes, associated with it a hollow flat body 4 with two pairs of coaxial holes 11 round 5 and elongated 6 for 1) carabiner 7 replacement. Prodo. The lined holes 6 are exchanged under the end face 8 of the washer and at an angle to it, and the holes 5 are mixed from the axis () () the holes of the washer in the direction of the tipo- to. 1G () 5th holes 6.

Case 4 can be broken in the form of a bracket, one pair of whose longitudinal faces is fixed on the washer, and to-free areas b () K () B1, g sides of it, protrusion 9 d.1 1C) Egba Rope P1rute.

Use the device as follows.

Fixed 1pc) pa) to the relief, a rope is inserted in a loop: in the hole 2 washers 1 and in Ko |) iiyc before it goes beyond its limits. In the pattern of work (speed (lycKa)) the carabiner is inserted into the hole 5 or H with the rope inside it.

To organize a sicus or insurance on a local area with the maximum probability of Pile 1P1 stones and with additional insurance - Koii from another insurance, for quickness of descent, use carabiner wiring through holes 5. With STOM, the safety branch K) of the rope is compressed. .1 is the re1 of the rope 11 at the point where the rope leaves the niaii6br Be; the first angle of the bend of the rope 10 and the hand compression of the rope n) the speed control is performed nro tg) av. First rope during descent and insurance.

The oblong hole 2 of the pipe 1 is short in comparison with the known constructions and is approximately six rope diameters, which makes it easier to work with icy rope. But in order to maintain the required girth angle of the body of the carabiner 7, the holes 5 are mixed from the symmetry axis of the hole 2 to the side of the safety loop And) there is such a distance so that |

the branches 10 and 12 of the rope came together, but there was no contact between them. This distance is approximately three rope diameters.

When passing through the hazardous areas, the carabiner is wired through oblong inclined holes 6. Under the action of friction forces and elastic forces of the rope, the carabiner moves in these holes, approaching the end 8 of the washer and presses the rope. For this purpose, the distance between the end of the 8 washer and the walls of the 13 holes was chosen to be smaller than the diameter of the rope. The safety branch 10 of the rope, the exit from the oblong hole of the washer, may be under the load of the regulating arm, and may be free from the load. In this case, you can prepare the tangled rope while descending.

If it is necessary to temporarily stop the descent, the safety branch 10 of the rope is pulled over the protrusion 9 onto the hull, the bend 14 is made and the hand is pressed against the karabiner. The adjusting arm is released for another job, for example for hooking.

The device provides a total angle of bending of the rope at 320 ° downhill and 380 ° 410 downhill to rocky places. which contributes to the insurance of pa-res insurance according to (Mo / krnosti xyr-1G1 rutah.
