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 a device for protecting a window opening, comprising an internal sash installed in the opening that opens into the room and an external fence of the opening with one constipation (RF patent No. 20177920 of 08.15.94, IPC E06B 9/02). 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 is transmitted through a lock to the internal fragile sash, which makes it easy to enter the room from the outside), limited functionality, the inability to quickly and remotely open the opening if emergency evacuation from the premises is necessary, 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 of 10/20/2003, IPC Е06В 9/02. 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 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. 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.

These shortcomings were eliminated in the fire protection device for window and door openings with an emergency opening mechanism for evacuation according to the patent of the Russian Federation for utility model No. 68049 dated November 10, 2007, IPC EV 06/02. However, the disadvantage of this device is the relative complexity of the locking mechanism, made in the form of a box-shaped case, inside of which is located at least one pair of spring-loaded guide plates with diagonal grooves made in them, latches are installed between the plates with fingers fixed to them perpendicular to the longitudinal axis, included in the diagonal grooves, and the latches have the ability to exit the housing for fixing the outer fence through made in m openings. 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 closest in principle of operation and technical essence to the claimed device is a fire-protection window grill (decision of the FIPS examination of 03.29.2010 on the grant of a utility model patent by application No. 20100144442/22 (011928) of 03/09/2010). A significant drawback of this device is the inability to independently evacuate people to the lower floors or to the ground. Sometimes this makes the task of salvation impossible.

The objective of the utility model is to create a reliable, multi-functional, reusable and easy-to-use device to protect the premises from penetrating into them through the balcony, as well as to quickly create transformable evacuation balconies and stairs for independent emergency evacuation of people from the emergency room to the lower floors or to the ground.

The technical result that can be obtained by using the utility model is its multifunctional use: in the form of a protective window grill, in the form of a transformable evacuation balcony and in the form of a transformable evacuation sliding ladder, which saves significant financial resources in the process of development, manufacture and operation only one device whose operation is equivalent to the operation of three devices. When using a single control system for all multifunctional window grilles, it is possible to implement control of all lattices as well as selectively by sections.

The problem is achieved in that the multipurpose window grill consists of a window frame, a window fence and a fixing device. At the same time, the window fence consists of two sections: one of which is a transformable evacuation balcony, and the other is a transformable evacuation ladder, while the upper part of the window frame is a common railing in the form of an upper horizontal power bar, which are fixed through single-link movable plates of the fixing device to the window opening, and the lower part of the window frame also represents a power rod, which is the edge of the bottom of the transformable evacuation balcony, which h multi-link movable plates of the fixing device is also connected to the window opening, while the transformable evacuation ladder is made integral.

Figure 1 shows the device multifunctional window grill in the initial state, figure 2 - the position of the main elements of the grille during its transformation into an evacuation balcony and staircase, figure 3 shows the appearance of the multifunctional window grill in the final state, and figure 4 - the appearance of a multifunctional window grill against the background of the window, where:

1 - window frame;

In the assembled state, the multifunctional window grill is assembled according to FIG.

The main parts of the multifunctional window grill are window frame 1, window grill 2 and a fixing device. In the assembled state, the evacuation window grill 2 is installed in the window opening from the street in front of window frame 1.

Window frame 1 is designed to accommodate and secure on it all the elements of the transformable evacuation balcony 3 and the transformable evacuation ladder 4, as well as its direct attachment to the window opening. It is assembled from power metal bars.

Window grille 2 is designed to directly protect the window opening from unauthorized entry into the premises of an apartment, office buildings, organizations and institutions, as well as to ensure its quick transformation into a transformable evacuation balcony 3 and staircase 4 for independent emergency evacuation of people from the emergency room to the lower floors or to the ground. It consists of two parts: a balcony 3 and a staircase 4. In turn, the window grill 2 is assembled from metal bars, which in the first case are the fence of the transformable evacuation balcony 3 by applying artistic metal ornament on its rods, and in the second case - steps transformable escape stairs 4.

In the initial state (protection of window openings from unauthorized entry into the premises), both parts of the window grill 2 are in the same plane.

The fixing device is intended for direct mounting of the multi-purpose window grill to the window opening and for holding the window grill 2 in a vertical plane, corresponding to the protection of the window opening from unauthorized entry into the apartment premises, as well as for holding it in the form of a transformable evacuation balcony 3 and a transformable evacuation ladder 4 in in case of emergency in the apartment or in the building. It consists of packages of movable plates 5 and 6, which are attached on one side to the upper part 7 of the transformable evacuation ladder 4, and on the other hand, to the window frame 1 (Fig. 2). At the bottom of the upper part 7 of the transformable evacuation ladder 4, a travel limiter 9 of its lower part 8 is installed.

The connection of all parts of the multifunctional window grill, which provides reliable protection of the apartment, as well as the premises of administrative buildings, organizations and institutions from penetrating into them from the outside through the window, is carried out in accordance with figure 1.

The operation of the device is as follows.

If it is necessary to urgently evacuate people from the premises in the event of an emergency, such as a fire, it is necessary to open (break, knock out) the window and break the non-force connection between the window grille 2 and the packages of movable plates 5 and 6 of the locking device while in the room and push the window grille 2 push.

Subsequently, under the action of gravity created by the moving parts of the multifunctional window grill, they independently make a plane-parallel movement in accordance with figure 2.

In the process of this movement, the lower part 8 of the staircase extends from the upper 7. This movement continues until the protrusion on it rests against the limiter 9.

After completion of the movement, the movable sections of the transformable evacuation window grill 4 occupy a position in accordance with FIG. 3. In this case, the upper movable plates 9 rotate and hold the ladder at a predetermined distance from the wall of the house. The lower movable plates 10 open and turn into a broken line pressed both to the bottom of the window opening and to the outer wall of the building.

Thus, the conversion of the window grill 2 into a transformable escape ladder 4 takes place.

In this case, the upper movable plates 5 of the fixing device are rotated and hold the upper horizontal power metal bar of the window frame 1 (Fig. 4). The lower movable plates 6 also open and turn into a broken line, pressed both to the lower part of the window opening and to the outer wall of the building, while simultaneously pressing the lower horizontal power metal bar of the frame to it.

After completion of the movement, the movable sections of the multifunctional window grill occupy a position in accordance with FIG. Thus, the multifunctional window grill is transformed into a transformable evacuation balcony 3 and a transformable evacuation ladder 4. In this case, the metal ornament mounted on the metal bars of the window frame 1 performs the function of the floor and the side wall of the balcony 3.

Further, after the device was transformed into a transformable evacuation balcony 3, the evacuation of citizens. At the same time, a person at the bottom of the transforming evacuation balcony 3 can help the victim by lowering him down through the hatch 11.

The developed device is reusable. To assemble a multipurpose window grill, it is necessary to pull the upper power metal bar of the window frame 1 from the side of the apartment (room). Moreover, after fixing the window grill 2 to the window frame 1, the movable elements of the developed device occupy the positions corresponding to figure 1 and figure 4.

In the case of using a single control system for all multifunctional window grilles, it is possible to implement control of all lattices as well as selectively by sections.

In the initial position, the proposed technical solution is a multi-purpose window grill, which performs the functions of three independent devices: a protective window grill, a transformable evacuation balcony 3 and an evacuation sliding transformable evacuation ladder 4. This saves significant financial resources in the process of development, manufacture and operation of only one multifunctional window grill equivalent to three devices.

The developed device in its initial position is small-sized, compact, can be transported and transported, can be installed both independently and in the process of building a house.

The operation of the proposed grids does not require special knowledge and skills and consists only in the periodic lubrication of moving joints.

Using the utility model allows you to create reliable, multi-functional and easy-to-use devices to protect the premises from penetrating into them through the balcony, as well as to ensure the rapid creation of a transformable evacuation balcony and a transformable evacuation ladder for independent emergency evacuation of people from the emergency room to the lower floors or to the ground.

The utility model is industrially applicable, as it can be manufactured using conventional technologies used in the manufacture of metal products.
