Description

The utility model relates to construction equipment, in particular to the design of safety devices, and can be used both to protect window openings from unauthorized entry into the premises of apartments, office buildings, organizations and institutions using the possibility of evacuating citizens in emergency situations, for example, in case of fire .

Patents are known which describe devices for protecting window openings that can be used for fire fighting purposes. For example, CN patents No. 200982146 dated November 28, 2007, IPC: ЕВВ 9/01; B44C 1/18; ЕВВ 9/02 "Pseudo-classic multifunctional protective windows"; CN No. 2009982150 dated 11.28.2007, IPC: ЕВВ 9/02; A62B 3/00; Е06В 9/02 “Emergent escaping protective window”, CN No. 2532221 dated 01/22/2003, IPC: Е06В 9/06; Е06В 9/06 “Lifting laminated locking type protective window fence”, CN No. 2516683 dated 10/16/2002, IPC: Е06В 9/04; Е06В 9/02 "Protective device with double-slide folding railing for window", CN 2443137 dated 08/15/2001 IPC: Е06В 9/06; ЕВВ 9/06 "Protective window". From an analysis of the data of protective window devices, it follows that the main problem of window openings of this type is the need to fulfill conflicting conditions: on the one hand, the reliability of the window grill, and on the other, the availability and ease of opening it from the inside in the event of an emergency (natural disaster, fire and etc.).

Partially, these shortcomings were eliminated in the device for protecting a window opening, comprising an internal sash installed in the opening that opens into the room and an external opening fence with at least one lock (RF patent No. 2017920, IPC ЕВВ 9/02 of 08/15/94) . This constipation is made in the form of a supporting element fixed in the opening and located between the supporting element and the inner leaf of the lever mounted at one end on an axis fixed to the outer fence. The disadvantages of this 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); limited functionality; the impossibility of quick and remote opening of the opening if necessary, emergency evacuation from the premises, for example, in case of fire.

These shortcomings are eliminated in the device for protecting a window opening according to the patent of the Russian Federation for utility model No. 33388 dated July 9, 2003, IPC ⁷ Е06В 9/02 dated October 20, 2003. In it, 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 fence, and the fence in its middle part is pivotally connected to a U-shaped swivel rod, hinged with anchors to the wall of the opening. In this case, the fence is equipped with a mechanism for its remote opening, made in the form of a spring-loaded rod entering the hole of the rod, to which a cable with a handle is fixed. The disadvantage of this solution is the insufficiently easy opening of the protective device in extreme situations, associated with the need to partially move the external fence into the interior of the room, which is undesirable, because all doors of public and crowded rooms should only open outwards, because, otherwise, during a panic in an emergency, such as a fire, they might be blocked.

The closest in principle of operation and technical nature of the claimed device is a fire protection device for window and door openings with an emergency opening mechanism for evacuation according to the RF patent for utility model No. 68049 dated November 10, 2007, IPC ⁷ Е06В 9/02.

However, the disadvantage of this solution is the relative complexity of the locking mechanism, made in the form of a box-shaped case, inside of which at least one pair of spring-loaded guide plates with diagonal grooves made in them is arranged to move, latches are installed between the plates with fingers entering them perpendicular to the longitudinal axis in diagonal grooves, and the latches have the ability to exit the housing for fixing the outer fence through the holes made in it. In turn, this device will require additional maintenance, as subject to prolonged storage in open climatic conditions. In addition, it requires significant work to finalize the openings themselves, which increases the cost of installing the developed devices in already manufactured buildings.

The objective of the utility model is to create a reliable, multi-functional, reusable and easy-to-use device for protecting rooms from penetrating through the balcony, as well as providing the ability to quickly create an evacuation balcony if emergency evacuation from the premises is necessary, for example, in case of fire.

The technical result that can be obtained using the utility model is to increase the reliability of the developed device, because it lacks details such as hinges, spring-loaded guide plates, diagonal grooves, clips, fingers. In addition, the durability increases, because the developed device requires only seasonal lubrication of moving joints and reduces the amount of refinement during its installation. The developed device is reusable.

The task is achieved in that the fire protection window grille consists of a frame with a guard and a locking device. At the same time, a subframe made of a metal corner is introduced into it, and the vertically located corners are made integral and interconnected movably and laply, while the frame itself with the guard is rigidly connected to the subframe and consists of two sections that can be rotated relative to a common intermediate horizontal power axis, and the locking device is made in the form of a set of movable plates, at one end of which a mount is made for connection with the frame, and at the other with a window opening.

In Fig.1 shows a General view of the fire protection window grille with a subframe and in Fig.2 - without a subframe, in Fig.3 - its position in the form of a lattice, in Fig.4 - the position of the lattice in the form of an evacuation remote balcony, and in Fig. .5-7 depict similar positions of the developed device, but with reference to the window window, where:

1 - window grill;

2 - locking device;

3 - subframe;

4 - frame;

5 - fencing;

6 - the upper part of the window grill;

7 - the lower part of the window grille;

8 - intermediate horizontal power axis;

9 - movable plates;

10 - mount for connecting to a window opening.

In the assembled state, the fire protection window grill is assembled according to FIG. 1 and FIG. 2.

The main parts of the fire protection window grille are window grill 1, locking device 2 and subframe 3. In the assembled state, window grille 1 and locking device 2 are located in a subframe 3 made of a metal corner. The subframe is installed in the window opening from the street in front of the window frame.

Window grille 1 is designed to directly protect window openings from unauthorized entry into the premises of apartments, office buildings, organizations and institutions, as well as to transform it into a balcony. It consists of a frame 4 with a fence 5. In turn, frame 4 is assembled from power metal bars, inside of which metal bars are rigidly fixed, on which, as a rule, an artistic metal ornament is applied.

In this case, the window grill 1 consists of two parts: the upper 6 and lower 7 parts, which can be rotated relative to the common intermediate horizontal power axis 8. In the initial state (to protect the window openings from unauthorized entry into the premises), both parts of the window grill 1 are in one ( vertical) plane.

The locking device 2 (figure 2) is intended for direct mounting of the fire-protective window grill to the window opening from its inner side, as well as for holding the window grill 1 in a vertical plane, corresponding to protecting the window opening from unauthorized entry into the premises of the apartments and to hold it in the form of an evacuation remote balcony in the event of an emergency in an apartment or a building as a whole. It consists of packages of movable plates 9, which are attached on one side to both the upper and lower horizontal power axes. On the other hand, they are fixed to the window opening through the fasteners 10.

The subframe 3 (Fig. 1) is designed to protect the packages of movable plates 9 from environmental influences, create and maintain an angle between the upper 6 and lower 7 parts of the window grill 1 in the emergency balcony mode equal to 90 ° and give the aesthetic appearance of a fire-protection window grill . It consists of a metal corner, and the vertically located corners are made integral and interconnected movably and laply, while the frame itself with a guard in the "lattice" mode is rigidly connected to the subframe by a destructive connection.

On the inner side of the corner, vertical power metal bars of the frame 4 are fixed and packages of movable plates 9 are placed.

The operation of the device is as follows.

The connection of all parts of the fire protection window grill in accordance with figure 1 and figure 2 provides reliable protection of apartments, as well as premises of office buildings, organizations and institutions from penetrating into them from the outside through the window.

If emergency evacuation from the premises is necessary in the event of an emergency, for example, a fire, it is necessary to open (break, knock out the window) and break the non-force connection between the window grill 1 and the packages of movable plates 9 while in the room and push the window grill 1 away from you (Fig. 2). To do this, it is better to use an intermediate horizontal power axis 8.

Subsequently, under the action of gravity created by the moving parts of the fire-protective window grill, they independently make a plane-parallel movement in accordance with Fig.3. After the completion of the movement, the movable sections of the fire protection window grill occupy a position in accordance with FIG. 4. In this case, the upper movable plates 9 exit from the corresponding blocks, open and turn into a straight line, holding the upper horizontal power metal bar of the frame 4.

The lower movable plates 9 also come out of the corresponding blocks of the frame 1, open and turn into a broken line, pressed both to the bottom of the window opening and to the outer wall of the building, while simultaneously pressing the lower horizontal power metal bar of the frame 4 to it.

Thus, the conversion of the protective window grill (Fig. 5 and Fig. 6) to the evacuation remote balcony (Fig. 7) occurs. In this case, the metal ornament, mounted on the metal bars of the frame 1, performs the function of the floor and the side wall of this balcony.

Further, after the device was transformed into a balcony, citizens are evacuated. Smoke and fire, as the practice of fires show, breaking out of a room into the street takes up to 2/3 of the window opening, and not rarely the entire window opening. Being on the evacuation balcony, citizens are relatively safe from fire and smoke, which actually ensures the moment of evacuation.

Using the utility model allows you to create reliable, multi-functional and easy-to-use devices to protect the premises from penetration into them through the balcony, as well as provide the ability to quickly create an evacuation balcony if necessary, emergency evacuation from the room, for example, in case of fire. The developed device is reusable. To assemble a fire protection window grill, it is necessary to pull the upper movable plates 9 from the side of the apartment (room). In this case, the movable elements of the developed device occupy the positions corresponding to FIG. 1 and FIG. 2, and after fixing the window grill 1 to the packages of movable plates 9, the device occupies the position corresponding to FIG.

In addition, this device is characterized by a decrease in the amount of refinement during its installation compared to other similar grilles.

The developed device can be installed both in the process of building construction and in the process of bringing premises to tenants or employees of relevant organizations and firms. In this case, the installation of fire protection window grills can be carried out both by specialists and non-specialists. Lattices for some period can independently be removed and installed. The operation of the proposed grids does not require special knowledge and skills and consists only in the periodic lubrication of moving joints.
