the presence of one row of cutting in the form of a safety rope and the presence of tensioning devices for flexible struts and a rope.

A device according to the patent of France No. 2589182, Cl. E 04 G 21/32, 04/30/1987, adopted by the applicant for the prototype. It contains racks, on the inside of which lodgements are installed to place rigid insurance in them. In addition, along the height of the rack, on its middle and top, brackets are fixed to accommodate flexible insurance. Each bracket is equipped with an element that locks flexible insurance against falling out, and each rack is made rigid and equipped with a clamp made with a vertical displacement drive.

However, this device has a complex structure for mounting the rack clamp on the floor, a complex structure of the element locking the flexible insurance.

The technical task of the utility model is to create a highly reliable and uncomplicated protection device working at heights, which does not require large expenses in the manufacture and installation on the building.

The problem is solved in that in the proposed device, the brackets for accommodating flexible insurance are made in the form of spiral loops and are mounted on racks by means of brackets with the ability to move in height, the tool holders for placing rigid insurance are mounted on racks with the possibility of vertical movement, equipped with clamps and made detachable.

In addition, the brackets are made detachable, and the socket of the lodgements and brackets is made in the form of a swivel.

In FIG. 1 shows a device for insurance in the working position; in FIG. 2 - device using hard insurance; in FIG. 3 - device using flexible insurance;

in FIG. 4 - lodgement attachment unit on the rack; in FIG. 5 - mounting bracket with a loop on the rack.

The device for insurance when working at height consists of a number of racks 1, fixed to the ceiling 2, rigid insurance 3 or flexible insurance 4, for example, a rope. It is possible to use combined insurance: both rigid insurance 3 and flexible insurance 4. All racks 1 are made rigid in the form of a welded structure. Each of them is equipped with a clamp 5, which has a vertical movement drive 6, which allows you to install and fix the rack 1 on the ceiling 2. On the inside of the rack 1, spaced along its height, two lodgements 7 are installed in the form of a “L-shaped bracket for placement in them hard insurance 3, which can be performed, for example, from the board. To fix the rigid insurance 3 in the lodges 7, clamps 8 are installed. The lodges 7 are mounted on the resistant 1 with the possibility of vertical movement and are made detachable. The connector is made in the form of a swivel joint 9. In the case when it is necessary to use flexible insurance 4 as a signal insurance, spiral loops 11 are mounted on the brackets 10 on the upper part of the rack 1 and on its middle part with the possibility of movement in height. There are more than two such loops 11, therefore, flexible insurance 4 can also be stretched in more than two rows. The brackets 10 are also made detachable, the connector of which is also made in the form of a swivel 9. For fixing the height of the rack 1 of the cradle 7 and the brackets 10, clamps 12 are mounted on them.

The device for insurance when working at height is mounted as follows.

set the required number of racks 1, necessary to protect the hazardous area. Using a swivel joint 9 and clamps 12, the required number of tool holders 7 and the desired number of spiral loops 11 on the brackets 10 are installed along the height of each rack 1. A rigid insurance 3 is placed in the tool holders 7, securing it with clamps 8. Using a rigid insurance 3 provides a more safe operation height. For "signal insurance of the boundaries of the working platform in the spiral loop 11 pass flexible insurance 4, for example, a rope.

Thanks to the use of the proposed solution, a not complicated, but highly reliable device for protecting workers working at heights was created, which does not require large expenditures not only during manufacture, but also when mounted on a building frame.
