Abstract

The utility model relates to a belay device for use in tourism, mountaineering, industrial work and rescue work and is an all-metal product consisting of a metal ring divided by a crossbar into two unequal semicircles: an upper larger semicircle and a lower smaller semicircle; the crossbar serves as a limiter for the movement of the carabiner, while the lower semicircle is designed for fastening the carabiner, and the upper semicircle is for threading the rope, on the side of the outer side of the metal ring there is a neck in the form of a protrusion for putting a rope behind it, at the end of the protrusion there is a lever directed upwards, with a hole in the upper part for a carabiner, and a horn pointing down and bent towards the ring, designed to grab the rope. 1 ill.

Description

The utility model is a safety equipment, equipment for rescue work and refers to devices used in tourism, mountaineering and industrial work. The principle of operation of the claimed technical solution is to create friction of the rope when passing through the structural elements of the device and reduce the load while holding the load. When control over the device is lost, its ring turns under load and the free end of the rope is automatically clamped. In this way, an automatic locking of the rope is achieved to prevent from falling and fixing. The release from the blockage and the movement of the rope in the device occurs when the lever is pressed. The speed of movement is controlled by the force of squeezing the free end of the rope by hand.

From the prior art, a technical device for the construction of a trigger safety mechanism is known (JP 1996052237 A, 06/23/1985 Self-locking descender). This safety descent device comprises a cam pulley provided with an actuating pin which cooperates with a mechanism having a transmission rod which releases the operating handle in the middle during the descent operation. An actuating pin that establishes a unidirectional mechanical connection between the operating handle and the pulley when put into position, and the operating handle has moved to the clutch release intermediate position, and automatically returns the cam to the fixed position by the pulling action of the cable. That is, it is configured such that the mechanical connection between the handle and the pulley is broken in the middle. Therefore, even after the pulley is released, the rope can be permanently fixed without applying constant force to the handle.

The implementation of the utility model is as follows.

The belay and descender device is made of an all-metal structure, does not have moving parts and mechanisms, consists of a metal ring divided by a crossbar into two unequal parts. The crossbar serves as a limiter for the movement of the carabiner, while the lower semicircle is intended for fastening the carabiner, and the upper semicircle for refueling the rope, which has a protrusion that protects the rope from overlapping, has a neck to the left of the ring, for which the rope is wound, having a lever directed upwards, with a hole in upper part for a carabiner, and a horn pointing down and bent towards the ring, designed to grab the rope. Threading the rope into the device occurs without removing it from the carabiner, which reduces the possibility of loss. The belay/rappel device provides the possibility of using a wide range of working rope diameters and provides the possibility of descending on a double rope with self-locking. The belay-rappel device has a lever curved to the left with a hole in the upper part for a carabiner.

The principle of operation of the proposed technical solution of the belay-rappel device is that the lever of the device is directed towards the intended load. A climbing carabiner is fastened into the lower semicircle and into the carabiner hole to secure the device on a belay system or at a belay station. A loop is formed from the rope so that the free end looks towards the lever. The loop is threaded into the upper large semicircle, from the back side, and pounces on the lever and horn, covering the neck. When loaded, the device is immediately in a locked state due to the fact that the carabiner slips in its sector, the ring turns, and the loaded branch of the rope presses the free end against the inside of the ring in the area where the crossbar adjoins. The characteristic is the high safety of the belay and descender, reliability and simplicity of design, ease of use, small size, light weight and high applicability, where insurance against falling of people working at height is required. This goal is achieved by creating a single structure that does not have mechanisms, moving parts and parts. According to its purpose, an all-metal rope-brake product without moving parts and mechanisms is a self-locking belay and descent device.

Comparative analysis with the prototype shows that the disadvantage of the known safety devices are moving parts and mechanisms, lack of reliability in their work due to the possible wear of moving parts and parts during their operation.

Distinctive features of the proposed technical solution is that the design of the belay-rappelling device is single without moving parts and mechanisms, having a small size and weight, easy to use, and in the proposed solution, not the cam pulley is turned and the rope is pressed by it, but the entire device in the carabiner and pressing the free end of the rope to the inner radius of the ring with a loaded branch of the rope, which leads to the cessation of movement.

The task that the proposed utility model is aimed at is the creation of an all-metal device that does not have moving parts and mechanisms with a wide range of working rope diameters (6-12) mm, low dependence on the diameter and condition of the rope with the possibility of descending a double rope with self-locking for prevention from falling and fixation, while threading the rope into the device occurs without removing it from the carabiner, which reduces the possibility of loss, simplicity and low cost of design, manufacture, and use.

Brief description of drawings:
