Description

The invention relates to the construction, in particular, to the design of safety enclosing devices, and can be used to protect against thieves the openings of buildings for various purposes.

Known protective device for door and window openings containing rods connected between each other by fencing elements, two guides mounted on opposite sides in the plane of the opening, and supporting elements / see RF patent No. 2209288, cl. EB06 9/01, 2001 /.

The disadvantages of the known protective device are the complexity and cumbersome structure, significant metal consumption, high complexity of manufacturing the device and relatively large dimensions (according to the conditions of installation and operation, the protective device is attached to the wall in the plane of the opening outside the dimensions of the window opening, which does not allow placing the protective device inside the window opening , this is especially important when mounting it to a wall in the plane of a window opening on the outside of the building - the architectural facade of the building is violated I and there is a significant laboriousness to ensure resistance to cracking fasteners).

The aim of the invention is to achieve a new technical result, which consists in a significant simplification of the design of the protective device, reducing the metal consumption and the complexity of its manufacture, in making it possible to place the protective device inside the window opening in the plane of the window frames from both the inside and the outside of the room with more reliable stability hacking fasteners (mounting) elements, without violating the architectural facade of the building and in ensuring the rapid release of the window opening the protective device in extreme situations.

A new technical result is achieved in that the protective device for window openings containing a fixed support frame made of a corner steel profile and rigidly fixed inside the window opening in the plane of the window frame, and a movable removable frame made of a steel pipe of rectangular cross-section, placed inside the support frame on the locking elements, while to the inner contour (around the perimeter) of the removable frame, the enclosing elements made of a cable orye interconnected by staggered overlaps compressed ties, thus enclosing the cables before fixing to the inner contour of the removable frame ends ropes in pairs compressed ties, and their ends are melted by welding.

Inside the fixed support frame on both sides of it in the plane of the window frame, T-shaped locking elements are rigidly fixed.

-образные отверстия под стопорящие элементы в опорной рамке.On mating surfaces on both sides of the removable frame in the plane of the window frame are made

-shaped holes for locking elements in the support frame.

The salient features of the claimed technical solution are:

- the protective device comprises a support frame made of a corner steel profile rigidly fixed to the inner surfaces of the shelves on two sides of the frame in the plane of the window frame with T-shaped locking elements, and a removable frame made of a steel pipe of rectangular cross section rigidly fixed to the inner the contour of the removable frame by electric welding of enclosing elements in the form of cables interconnected in a checkerboard pattern by means of overlaps pressed by couplers, while in front of trosvarkoy to the inner contour of the ends of the load-bearing cable ties mutually compacted, and their ends are melted by electric welding;

- placement of a protective device (support frame with a removable frame inserted into it on the locking elements) inside the window opening in the plane of the window frame;

- lack of guide cables;

- lack of movable and fixed rods made in the form of a pipe;

- the absence of support elements in the form of movable earrings and travel brackets.

These significant distinguishing features ensure the achievement of a new technical result.

Placing the removable frame with the web of enclosing elements rigidly fixed inside it in an extended state inside the support frame on the locking elements allows a number of important technical solutions to be implemented:

- more than halves the complexity of manufacturing, since the design of the protective device excludes all parts and assemblies for folding and stretching the canvas of the enclosing elements;

- reduces metal consumption by more than 30% by reducing the size of the protective device and simplifies its design;

- provides reliable resistance to cracking of fasteners of the supporting frame to the opening, since they are all blocked by a removable frame inserted into the supporting frame on the locking elements and locked by a locking device;

- the principle (method) of protecting and releasing the window opening from the removable frame with the enclosing cable rope allows you to place a protective device inside the opening without violating both the interior of the room and the external facade of the building.

The invention is illustrated by drawings, where figure 1 shows a General view of a protective device; a removable frame is inserted into the support frame on the locking elements and locked on them by a locking device, the opening is closed; figure 2 is a section aa in figure 1; figure 3 - place I in figure 1; figure 4 is a section bB in figure 1; figure 5 - place II in figure 1; figure 6 - section bb in figure 5; in Fig.7 - place III in Fig.1; in Fig.8 is a section GG in Fig.7.

Съемная рамка 2 внутри нижней трубы содержит две пружины сжатия 8 (фиг.5, фиг.6) с выжимными штоками 9 и прочностную проставку 10 из троса по всему периметру рамки (фиг.2, фиг.4).The protective device comprises a support frame 1 made of a steel corner profile with rigidly fixed locking elements 7 to the side shelves in the plane of the window frame (Fig. 2), and a removable frame 2 made of a steel pipe of rectangular cross section with its enclosure rigidly fixed to the inner contour with a web 6 made of a cable by means of electric welding, while the ends of the cables of the enclosing web 6 are pre-pressed in pairs by ties 3 and are fused by electric welding (Fig. 3), and the outermost cables are fencing giving cloth 6 in the middle of each cell are pressed by a sleeve 5 (figure 4). In the removable frame 2 are made

-shaped holes for locking elements (Fig.7, Fig.8), the number of which is determined by the requirements for resistance to breaking. The removable frame 2 inside the lower pipe contains two compression springs 8 (Fig. 5, Fig. 6) with release rods 9 and a strength spacer 10 from the cable around the entire perimeter of the frame (Fig. 2, Fig. 4).

-образных отверстий в съемной рамке 2 шириной d+1 мм. Стопорящие буртики, находясь внутри трубы съемной решетки 2 в зоне пазов с размером d своими заплечиками D1-d исключают какие-либо перемещения съемной рамки 2 (фиг.7, фиг.8). В этом состоянии съемная рамка 2 фиксируется (блокируется) механическим или электромеханическим запирающим устройством (на чертеже не показан). Оконный проем закрыт.The protective device operates as follows. To close the opening, it is necessary: insert the removable frame 2 all the way into the support frame 1, which is rigidly fixed inside the window opening with fasteners 11, while the locking elements 7, rigidly fixed to the supporting frame 1 by the locking collars with a diameter of D1 (Fig. 8), enter the inside of the removable frame 2 through holes D (Fig.7). Holding the guard web 6, apply some force and move the removable frame 2 down to the stop with the lower shelf of the support frame 1, overcoming the elastic force of the compression springs 8. In the process of moving the removable frame 2 down, it is simultaneously locked by all locking elements 7 in the plane of the perpendicular plane the window frame, since the locking elements 7 rods with a diameter d enter the grooves

-shaped holes in a removable frame 2 with a width of d + 1 mm. The locking collars, being inside the pipe of the removable grill 2 in the area of the grooves with size d with their shoulders D1-d exclude any movement of the removable frame 2 (Fig.7, Fig.8). In this state, the removable frame 2 is fixed (locked) by a mechanical or electromechanical locking device (not shown in the drawing). The window opening is closed.

To open the opening, you must open the locking device. Under the influence of the elastic forces of compression springs 8, the removable frame 2 is displaced all the way to the upper shelf of the support frame 1, while the locking flanges D1 of the locking elements 7 are aligned with the holes D in the removable frame 2. The removable frame 2 is removed from the supporting frame 1. Window the opening is open.
