Description

 The invention relates to the sport, in particular for the insurance of climbers, and can also be used when performing construction and repair work.

FIG. 1 shows a device with a single rope filled with a perspective view; FIG. 2 - the same, with two safety ropes tucked in for work, longitudinal section; Yu force and each rope (or both veins of Fig. 3 - the device in the position of dynamic braking, in Fig. 4 - the scheme of laying the loop of the rope for fixation after the failure of the partner.

The device contains an L-shaped in longitudinal section plate 1 with a hole 2 (FIGS. 3 and 4) under the carbine

3 in the vertical section and the holes 4 for the rope in the horizontal section with their axes parallel to the plane of the vertical section and protrusions arranged at an angle to one another by the rope. The protrusion 5 is made sickle-shaped in cross section and placed on the vertical section of the plate above the hole 2 under the carabiner,

and the other 6 is under the horizontal section of the plate and in the plane of its vertical section. Hole width

4 is 1.1-1.2 times the thickness of the ropes, and the length of the protrusion 5 is equal to twice the thickness of the rope.

The device is used as follows.

In the ready position (Fig. 1 and 2) loops of the ropes 7 and 8, drawn through the slots 4 and clicked on the karabi 3, bend around the upper surface of the arch

shaped protrusion 5. The release of the safety rope is made in the direction of arrows A and B (Fig-1) with two hands.

When the rope breaks, the rope is pulled and the loading of the system unfolds it along with the carabiner (Fig. 3) in such a way that the axis of symmetry becomes perpendicular to the action.

together) receives additional kinks in zones 9 and 10, which automatically creates an increase in the strength of friction in the system, regardless of the qualifications of the insured. In this case, the rope works without sharp bends, the surface of the protrusion 5 ensures the stability of the friction force.

To fix the rope (Fig. 4), the branch of the rope coming to the device after braking and stopping the fall is passed through a loop 11 into the lumen of the carabiner 3, the loop is thrown onto the locking protrusion 6 and tightened until it locks. The additional bend loop created in this way stably ensures fast and reliable fixation of the rope regardless of qualification and experience.

insurer.

The proposed device can be used during descents on single and double ropes. At the same time, it allows fixing the double rope, as well as separating the branches of the trigger rope, which facilitates the work of the latter in the group and creates additional convenience of use.
