Description

The proposed utility model relates to personal protective equipment against falling from a height and can be used as part of a fall protection safety system for high-altitude work, for example, on roofs or walls of buildings. An anchor safety device includes a rigid anchor line fixed to the support in the form of a shaped profile and a slider device with an anchor point to which the installer is insured to be moved along the profile.

The level of technology.

A device for moving along a rigid anchor line is known, see RF patent No. 180367 from 06/08/2018. This device contains a rigid anchor line in the form of a T-shaped profile and a slider moving device with an anchor point, made in the form of a housing with the ability to cover the T-shaped profile of a rigid anchor line. The disadvantage of this device is the limited use, due to the difficulty of attaching a T-shaped profile to the supporting structure.

The closest technical solution is the horizontal anchor safety device "MARAN", described in the Protekt catalog, https://sizcontract.ru/catalog/statsionarnye_ankernye_linii/gorizontalnye_sistemy_strakhovki/maran_protekt/. This device includes a rigid anchor line in the form of a cross-shaped profile, installed with its two adjacent protrusions in brackets mounted on a support, and, moved along the profile, a slider device with an anchor point to which the installer is insured.

The disadvantage of this device is the lack of reliability, due to the low reliability of the connection of the bracket and profile.

The technical result of the utility model is to increase the reliability of fastening the anchor safety device.

The technical result is achieved by the fact that the anchor safety device includes a profile, the upper and lower parts of which form protrusions in the form of a dovetail, at least one bracket mounted on a bearing surface and having a groove in shape similar to the shape of a dovetail "To install the above profile into it, and a slider device with an anchor point, also having a dovetail-shaped groove mounted on the protrusions of the above profile and configured to move along it, tlichayuscheesya in that the lower part of the profile is a T-shaped groove, and the bracket fixed on the bearing surface, has a T-shaped projection for mounting it in the profile.

Preferably, the bracket should be in the form of an I-beam.

The upper side walls of the T-groove can be made at an angle to the vertical plane of symmetry of the profile.

A slider device with an anchor point may have a means of fixing to the profile.

In addition, on the profile should be additionally installed means restricting the movement of the slider device.

Also, the slider device in its design may contain rollers, ensuring its smooth movement along the profile.

The essence of the claimed utility model is illustrated by drawings of FIG. 1-3 where

in FIG. 1-2 shows the design of the prototype;

in Fig.3 shows the contours of the profile used in the proposed anchor safety device;

in FIG. 4 shows a profile photo used in the proposed device; in FIG. 5 shows the proposed device.

In the figures, the positions indicate the following positions:

1 - profile

2 - T-shaped groove.

3 - protrusion profile type "dovetail"

4 - slider device

5 - rollers,

6 - locking screw.

The proposed anchor safety device shown in FIG. 3, works as follows.

At least one bracket (as a rule, two or more brackets are used) having a T-shaped protrusion tightly fastens to the bearing surface (not shown in the figures), it can be either horizontal or vertical bearing surface. Moreover, if there are several brackets, then they are mounted at the same level. After that, the profile 1 is inserted into the T-shaped protrusion of the brackets with its lower T-groove 2, profile 1 and fixed with fasteners. In the fixed profile, namely in its upper (free) protrusions, which form essentially a dovetail mount, a slide device 4 is inserted (see Fig. 5), then the slide stops of the slide device are attached, after which the installer can fasten the carabiner to the anchor point slider device and work. The lower T-shaped groove 2 and the upper protrusions 3, forming essentially a dovetail mount, are made along the entire length of the profile. In this case, the concepts of the lower groove and the upper protrusions are relative, because when using the profile on the ceiling, the lower T-shaped groove will be at the top and the dovetail protrusion will be at the bottom.

The slider device 4 may also have rollers 5 in its design, ensuring its free sliding along the profile, as well as means for temporarily fixing it on the profile, for example, a locking screw 6.

At the same time, the working length of the profile and the slider device moved along it can be arbitrarily large and is selected as necessary from the tasks set.
