Description

The utility model relates to safety devices and can be used as personal protective equipment against the fall of people at altitude.

Known mounting device for mounting on the roof or wall of a building with the possibility of mounting a person during work at a height [RU 135931, U1, A63B 29/02, 12/27/2013], containing the form-holding main part with at least one mounting element, and containing a flexible plate extending to the side of the main part with a free distal part, and designed and made with the possibility of attachment to the surface of the object, and the main part contains made in one piece holding the body with a solid base, while, prok imalnaya portion of the flexible plate tightly mounted in the housing base and the distal portion of the flexible plate moves away from the main portion.

The disadvantage of this technical solution is the relatively narrow functionality to provide protection against falling in a narrow area of human movement in the horizontal direction.

A device is also known for insurance and movement of a user on a rope [RU 135931, U1, А63В 29/02, 12/27/2013], consisting of a support bracket with a hole for a carabiner, moreover, a latch is connected to the support bracket with a hole in the form of a pressure bar at the same time, the latch is made with the possibility of displacement along the bracket into the working position so that the holes of the bracket and the latch are combined to engage the carbine of the safety system.

The disadvantage of this technical solution is the relatively narrow functionality to provide protection against falling in a narrow area of human movement in the horizontal direction.

The closest technical solution to the claimed one is an anchor device for individual protection against falling when working at height [RU 171935, U1, E04G 21/32, 06/21/2017] containing a supporting base and an anchor eye for mechanical attachment of safety devices, and the supporting base is a top anchor, with fasteners for the upper anchor on the supporting structure, and a lower anchor with fasteners for the lower anchor on the supporting structure along a common vertical axis with the upper anchor, and the safety device This is made in the form of a cable, the upper end of which is connected to an anchor eye fixed to a shock absorber mounted on the upper end of a metal strut mounted on the upper anchor and provided with fastening elements on the supporting structure, and the lower end is placed in the cable tension element fixed on the lower end the lower anchor, as well as the cable holder, made with the possibility of limiting the deviation of the cable from a vertical position, and a slider placed on the cable and made with the possibility of fastening to it with user protection features.

The disadvantage of this technical solution is the relatively narrow functionality to provide reliable protection against falling when moving the object of protection (person) horizontally.

The objective of the utility model is to create a reliable stand-alone device for individual protection of a person from falling when working at height, ensuring that it can be moved horizontally over a wide range of distances, including moving through protrusions and corners of building structures, and expanding, on this basis, the arsenal of personal protective equipment people from falling when working at height with the need for horizontal movement over relatively large distances.

The required technical result is to expand the functionality of the device by providing reliable individual protection against a person falling when working at height with the possibility of horizontal movement over a wide range of distances.

The problem is solved, and the required technical result is achieved by the fact that, in the device, a safety device made in the form of a cable, bearing a base containing two end anchors made with the possibility of mounting on a supporting structure, a shock absorber with a cable tension element through which one end the cable is fixed on the corresponding one end anchor, the cable tension element through which the other end of the cable is fixed on the corresponding other end anchor, and the slider placed on dew and containing the eye, which is made with the possibility of attaching the user protection means to it, according to the utility model, intermediate anchors are inserted horizontally with two end anchors and configured to fasten their base on the supporting structure, while each of the intermediate anchors contains a protrusion connected to its base, on which a tubular bend is placed, made with the possibility of covering the cable, and the slider contains a bending attached to the ear, making with the possibility of covering the tubular bends of the intermediate anchors and the free passage of the protrusions of the intermediate anchors through the gap between the end of the bend of the slider and its ear when the slider moves along the cable.

In addition, the desired technical result is achieved by the fact that the cable is equipped with an intermediate anchor insert containing a tube made with the possibility of pulling the cable in it and containing end anchors at the ends made with the possibility of fastening on the supporting structure.

The drawing shows:

In FIG. 1 - an example of the implementation of the anchor device of individual protection against falling when working at height using one intermediate anchor insert;

in FIG. 2 - an example of the design of the slider;

in FIG. 3 is an example of a structural embodiment of an intermediate anchor.

An anchor device for individual protection against falling when working at height contains a safety device in the form of a cable 1 and a supporting base containing two end anchors 2 made with the possibility of mounting on a supporting structure.

In addition, the anchor device for individual protection against falling when working at height contains a shock absorber 3 with a tension element through which one end of the cable 1 is fixed to its corresponding one end anchor 2, an element 4 of the cable tension through which the other end of the cable is fixed to its corresponding other end anchor 2, and the slider 5, placed on the cable 1 and containing the eyelet 6, which is made with the possibility of attaching to it the user protection.

An individual fall protection device when working at height also includes intermediate anchors 7, placed horizontally with two end anchors 2 and made with the possibility of mounting its base 8 on a supporting structure. At the same time, each of the intermediate anchors 7 contains a protrusion 9 connected to its base 8, on which a tubular bend 10 is placed, made with the possibility of covering the cable 1.

In the anchor device for personal protection from falling when working at height, the slider 5 is an enclosing bend 10 mounted on the ear 6, configured to cover the tubular bends 10 of the intermediate anchors and freely pass the protrusions 9 of the intermediate anchors 7 through the gap between the end of the covering bend 10 of the slider 5 and his eye 6 when the slider 5 moves along the cable 1.

In the case of working with supporting structures of complex shape, the cable 1 can be equipped with an intermediate anchor insert 12 containing a tube 13, configured to pull the cable 1 in it and end anchors 14 of the intermediate anchor insert, made with the possibility of mounting on the supporting structure and performing similar functions functions of intermediate anchors 7 and having a similar construction with them.

Anchor device of individual protection against falling when working at height is used as follows.

The user secures, for example, with the help of a carbine (sling), a leash or other means placed on it. Free movement of the user is ensured by the slider 5, which moves freely along the cable 1. In an emergency, the slider 5 placed on the cable 1 eliminates the fall, and the shock absorber 3 mitigates the impact on the user in case of disruption from the supporting structure or holding devices.

Thus, the proposal ensures the achievement of the required technical result, since the reliability of the individual protection device from falling when working at height in stand-alone operation mode is increased, and its functionality is expanded, as it is used to work with free horizontal movement of the user in any range of distances, including when moving on load-bearing structures of complex angular shape.
