Description

The utility model relates to the field of construction, in particular to the designs of safety fencing devices for window openings, and can be used to protect children, animals and objects from accidentally falling out of the window. The device for preventing loss of windows made quick-detachable and provides the ability to quickly and easily dismantle in emergency situations.

Known protective window grill to prevent falling out of the window (RU No. 108081 U1) which is mounted from the outside of the window, directly on the frame. A device made of metal vertical and horizontal rods connected by a welded joint provides complete or partial overlapping of the opening part of the window.

The disadvantages of the known device are the need to install it from the outside of the window (from the street), fasteners directly to the imposts, which violates the integrity of the window profile chambers and causes the formation of so-called "cold bridges", which can affect the thermal conductivity of the window; relatively large labor costs and material consumption of the manufacture of the device, excessive massiveness; the complexity of both mounting and, if necessary, dismantling the structure with the obligatory involvement of qualified specialists; if there is no need for further operation (children grew up, selling an apartment, etc.) after the device is dismantled, installation traces will remain on the window box, which will lead to the need for its replacement; the need to manufacture the device individually for each window, which excludes its mass production; a ban on the installation of blind (non-swinging) gratings on the ground floors (Federal Law No. 123 “Technical Regulations on Fire Safety Requirements”, subparagraph 3, part 1, article 80) Structural, space-planning and engineering solutions of buildings and structures should be provided in case of fire : the possibility of access to the personnel of the fire protection units and the delivery of fire extinguishing means to any room of buildings and structures ”), which means that such a device cannot be installed in kindergartens, hospitals, etc.

The closest technical solution (prototype) is a device for preventing falling out of windows (RU No. 162076 U1), comprising a removable wall covering with a reinforced edge portion, fixed at least on two opposite sides of the window frame to a non-facing external surface in the window’s inner space profile.

A disadvantage of the known device for preventing loss of windows is the complexity of the design and the complexity of its installation and / or dismantling, as well as insufficient reliability.

The technical problem, which the utility model aims to solve, is to eliminate the above disadvantages, namely the development of an easy-to-manufacture, assemble and / or dismantle, reliable design to prevent falling out of windows, children, animals and objects.

The solution to the technical problem lies in the fact that the device used to prevent falling out of windows includes a top with grooves and a bottom horizontal metal pipes of square section and vertical metal rods connected together in a single rigid system using a welded joint, fasteners made in the form movable and fixed metal rods for installation directly in the window frame profile in the vestibule area of the rotary shutter.

The inventive utility model is illustrated by drawings, where in FIG. 1 shows a general view of a device for preventing loss of windows; FIG. 2 is a mounting diagram of a device for preventing loss of windows; FIG. 3 fastening the device to prevent falling out of the windows into the window frame profile in the vestibule area of the pivoting sash.

The device for preventing falling out of windows contains an upper horizontal metal pipe of square section 1 with grooves 2, a lower horizontal metal pipe of square section 3, vertical metal rods 4, movable metal rods 5, retaining bolts 6 with an internal hexagon, nuts 7, knurled screws 8 , fixed metal rods 9, mating strips 10.

The device for preventing falling out of windows (Fig. 1), including an upper horizontal metal pipe of square section 1 with grooves 2, a lower horizontal metal pipe of square section 3 and vertical metal rods 4, interconnected into a single rigid system using a welded joint, is attached at four points in the light opening of the pivoting leaf into the lower and side imposts of the window box in the holes 11 and 12 (Fig. 2) in the area of the vestibule 13 of the pivoting leaf 14 (Fig. 3) using two fixed metal the rods 9 in the lower part, which enter the openings 11 of the narthex, through the holes of the reciprocal strips 10, mounted on the narthex of the window box and two movable horizontal metal rods 5 located in the upper tube of square cross section 1, telescopically entering the side holes 12 of the impostor of the narthex of the rotary shutter through the holes of the reciprocal strips 10. In this case, the upper pipe of square section 1 is equipped with two welded nuts 7 located above the holes drilled in the pipe, as well as entering through them with a cut connection with locking bolts 6 with an internal hexagon serving as fixing elements for movable metal rods 5. The movable metal rods 5 located in the upper square tube 1 are driven by knurled screws 8 passing through the movable metal rods 5 using threaded connections and which are also additional elements of their fixation.

The reliability of the device to prevent falling out of windows is ensured by its fixing in the holes 11 and 12 of the impost box located in the narthex 13 of the pivoting leaf 14, with the help of movable 5 and fixed 9 metal rods into the profile by at least 20 mm in each hole with additional reinforcement the openings of the window box profile with metal strips 10. In this case, the movable metal rods 5 are securely fixed in the window profile by two bolts 6 with internal hexagons, which eliminates them free twisting by children, as well as two knurled screws 8, passing through the movable metal rods 5 using a threaded connection.

During the tests, the experimental model of the device from falling out of windows for three days was subjected to a vertical load of 60 kg. As a result of the tests, the deformation in the central part of the device did not exceed 3 mm. This indicates a safety margin sufficient for safety. During the tests, no deformation traces were found in the places of fastening the window profile.

The distance between the vertical metal rods 4 is calculated based on the minimum size of the object that needs to be protected from falling out.

The height of the device for preventing from falling out of the windows is at least 1000 mm and does not have horizontal support elements, which completely excludes the child from overcoming the device for preventing from falling out of the windows.

Installation of a device to prevent falling out of windows does not require coordination with the Architectural and Planning Department and submitting an application to the Housing Inspectorate, as is the case with deaf lattices of external fastening, since it is not a facade work and the facade of the building does not change.

The device for preventing from falling out of windows meets fire requirements, as it is quick-detachable and can be recommended for installation in child care facilities (schools, hospitals, recreation camps, kindergartens, etc.).

The aesthetic appearance of the device to prevent falling out of windows is achieved by the possibility of using a wide range of colors (white, mosquito net, rainbow color if the device is installed in a children's room, etc.)

The universality of the use of the device to prevent falling out of windows is as follows: firstly, there is no need to manufacture the device for measurements individually for each window, which does not require the involvement of qualified specialists, since a unique design feature is the use of movable, fixing, side, metal rods 5 telescopically extendable by a maximum of 100 mm in each direction (essentially limited). The restriction is achieved by the length of the grooves 2 on the upper square tube 1, used to move the knurled screws 8, so that when entering the window frame profile by at least 20 mm, the step width from the axis of the extreme vertical rods of the device to the box impost also does not exceed the step the rest of the rods. For example, a device of six vertical metal rods with a step along the axes of 85 mm can be installed on windows with an open light opening range from 435 mm to 595 mm. Thus, two types of products with six and seven vertical metal rods are enough to cover the range of the open light opening from 435 mm to 678 mm. Secondly, the universality of the use of the device from falling out of windows lies in the fact that installing the device on the window frame impost in the area along the narthex axis 13 of the pivoting leaf 14 does not interfere with the full use of the pivoting or pivoting and folding flap in any operating conditions, as well as unhindered use mosquito net 15 (Fig. 3).

In the absence of the need for further operation (children grew up, selling an apartment, etc.), as well as emergency situations, the device to prevent falling out of windows can be easily dismantled by loosening the locking bolts 6 with internal hexagons of the movable metal rods 5, and the holes 11 and 12 on the window profile to close with decorative caps.

The use of the inventive device for preventing loss from windows provides a solution to the tasks, namely, providing protection against accidental loss of children, animals and objects from the window, reliability and simplicity of design, reducing the complexity of its installation and / or dismantling.
