DEVICE FOR PROTECTION

The utility model relates to construction equipment, in particular to the design of safety devices, and can be used both to protect door and window openings from penetrating into rooms from outside, and to open the opening in case of an emergency.

As a prototype, a device for protecting a door or window opening was selected, comprising an internal sash installed in the opening that opens into the room and an external

fencing of the aperture with at least one lock made in the form of a support element fixed in the aperture and located between the support element and the inner leaf of the lever mounted at one end on an axis fixed to the outer fence, RF patent No. 2017920, IPC E 06 V 9/02 , published 08/15/94, bulletin No. 15.

The disadvantages of the known device are:

-low reliability (the load from the external fence through the lock is transmitted to the internal fragile sash, which makes it easy to penetrate the room from the outside, for example, pull the fence with a lever until the internal sash or its hinges break);

-limited functionality (the outer fence can be locked only if there is an internal wing and the device cannot be used to protect openings without internal wings);

- the impossibility of remote opening of the opening if emergency evacuation from the premises is necessary, for example, in case of fire.

The objective of the utility model is to create a reliable, multi-functional and easy-to-use device to protect a window or doorway from entering the room from the outside, which also provides the ability to quickly remotely

opening the opening if necessary, emergency evacuation from the premises, for example, in case of fire.

To achieve this objective, a device is proposed for protecting a window or doorway from entering the room from the outside and opening the opening from the inside of the room, containing an external fence of the opening with at least one lock, in which, according to a utility model, the locks are made in the form of anchors with support pins are rigidly fixed on the wall of the opening and interact with the counter holes of the guard, and the guard in its middle part is pivotally connected to a U-shaped swivel rod, hinged with anchors to the wall of the opening, while the fence is equipped with a mechanism for its remote opening, made in the form of a spring-loaded rod that enters the hole in the rod, to which a cable with a handle is fixed.

A comparative analysis of the claimed device with the prototype and other solutions in the art shows that the set of features described is unknown from the existing level of technology, on the basis of which we can conclude that it meets the criterion of a useful novelty model.

The compliance of the proposed utility model with the criterion of industrial applicability is seen in the example of a specific embodiment of the device for protecting a window or doorway.

The utility model is illustrated in the drawing, in which in FIG. 1 schematically shows a General view of a device for protecting a window or doorway from entering the room from the outside (in the closed position of the grate), FIG. 2 - open position of the grate.

A device for protecting a window or doorway from entering the room from the outside comprises an outer fence 2 pivotally fixed in the opening 1, made in the form of a grating or a solid shutter. In the opening 1, on the anchors 3, jcinopHme pins 4 are fixed, which are inserted when the fence 2 is in the closed position

mating holes 5. The guard 2 in its middle part is pivotally mounted on a U-shaped rotary rod 6, hinged 7 to the wall of the aperture 1 using anchors 8. The grill 2 is equipped with a mechanism 9 for its remote opening, made in the form of an entrance to the hole 10 of the rod 6 of the spring-loaded rod 11 to which the cable 12 is fixed with a handle 13 at the end. To exclude quick detection by unauthorized persons and obstacles to the uncontrolled opening of the fence, the handle 13 with a cable is placed inside a box (not shown), mounted on the wall of the room and painted red with a sealed glass broken in case of fire.

The operation of the device is as follows.

When the outer guard 2 is closed (FIG. 1), the support pins 4 are located in the counter holes 5 of the guard 2, and the spring-loaded rod 11 is located in the hole 10 of the rod 6, which prevents the rotation of the rod 6 and the exit of the guard 2 from engaging with the support pins 4. This ensures reliable protection of the premises from penetration into it from the outside through the opening 1.

If emergency evacuation from the premises is necessary, the sealed glass of the box is broken and the cable 12 is pulled all the way to the handle 13. The spring-loaded rod 11 leaves the hole Yu of the rod 6, allowing the latter to freely rotate on the hinges 7. The guard 2 is rotated in its middle part relative to the U-shaped rod 6 and disengages from the support pins 4. With a slight push of the guard 2 from the inside, the U-shaped rod 6 is rotated 180 °, which ensures the complete opening of the opening 1 from the guard 2, as shown in Figure 2.

The use of the utility model makes it possible to dry; significantly increase the reliability and usability of the device for protecting a window or doorway from entering the room from the outside, expanding its functionality by providing quick remote opening of the door if emergency evacuation of people from the room is necessary, for example, in case of fire.
