Description

DESCRIPTION

FOLDING AND FOLDABLE ARPON FOR MASSIVE RESCUE IN BUILDINGS

The present invention refers to a folding and foldable harpoon model of easy mobility and installation, which is deployed and installed in a window, or an opening to the outside for such purpose built. Once placed, the harpoon releases a reel with steel cable, installed and connected to the pen that is outside the facade. The reel, its cable or both reach the ground, allowing its use by rescue and extinction teams, to get to the place of installation, which could not get otherwise. Thus, a rescue route is established for all neighbors and pets near the site and an access point to attack the fire.

BACKGROUND OF THE INVENTION

In fires, buildings with heights greater than 50 meters (some 16 floors) represent a complex operation for rescue and suffocation activities.

Operability on scales over 50 meters in height decreases, making it difficult for firefighters to work, since they must withstand the oscillations caused by the wind and the weight of rescued people and hoses to put out the fire.

In Spain, the three highest fire-fighting trucks are in Valencia, Vigo and Madrid, with 55, 55 and 53 meters in height, respectively.

For each meter of height of the scale, 2,500 Kg are needed at the base, making large platforms that are currently not viable.

For this reason, from 50 meters, firefighters bet on the self-protection of buildings.

The Grenfell building, in the North Kensigton district (London), is a building constructed in 1974. With a height of 70 meters, it has 24 floors and 120 houses, where 600 people lived. On June 14, 2017, a fire started on the fourth floor after the explosion of an electrical appliance, towards 1.15 at night.

200 firefighters and 40 fire engines worked tirelessly in the extinction and rescue. Towards 18.15, the fire segma without being suffocated.

There was no way to access the upper floors. At the date of this text, 65 people were rescued and 79 lost their lives, although it is suspected that the number can reach the "three figures".

Rania, 30, was trapped next to several of her neighbors in a floor of the 23rd floor. Retransmits live her situation through Facebook. The video shows how he asks for help from his window. The smoke sneaks in just through the entrance door to the building, when he opens it to call his disoriented neighbors.

The video shows that there is no fire or smoke in its entire façade. However, there is no rescue activity in this area. Today nothing is known about her or her neighbors.

The logistics for rescuing people in housing blocks is complex and expensive. The effectiveness of rescue work depends to a large extent on the speed of execution. Block a truck-scale and extend its scale completely, it means locating a street wide enough, free of obstacles, firm and horizontal. The effectiveness of the rescue will be limited to the maximum height of the scale.

In short, the problem of rescuing people or fire suppression measures lies in the height limit and accessibility in buildings over 50 meters high (about 16 floors).

At present, there are rescue teams that use a reel and anchor cable in the place of escape, they are individual equipment, of a single use and of very little height.

DESCRIPTION OF THE INVENTION

The object of the present invention is to establish a folded rescue equipment in buildings, with the possibility of being transported, deployed and installed by any person with a minimum of preparation, in any window (or window specially constructed for the invention) to facilitate, to the rescue teams on the street, an access road for the rescue and the extinction of the fire.

The assembly is stored and transported in a folded state and in a vertical position. Once the window for its installation has been chosen, it will proceed to its horizontal position.

A robust pen is the center of the set. The end that, in vertical position is in the base, receives the assembly of the axes of at least two diverging claws, which converge on the pen in its folded state. As a means of restraint and equal opening, the assembly is articulated with a stretcher for each claw. Each stretcher is joined to its claw by means of a shaft attached to it at a mid point. The other end of each stretcher is joined in axes fixed to a bushing that slides along the length of the boom.

The high end of the boom, which is then outside the facade of the building, has a locking mechanism to hold a reel with steel cable. The underside of the boom, once the assembly is installed, has a rail through which it can circulate and from which hangs a robust return pulley on which the cable of the reel rests.

The low end has a hole to receive the bracket of some accessory legs that consolidate the stability of the set, once installed.

The set has a base with wheels, for storage and transport in vertical position.

For its installation, it has a folding lever with the foot, located at the base of the set. The lever releases the locks that block the fall of the claws. The claws descend at a gradual speed thanks to a brake installed in the hub.

The clamps reach their final position of maximum opening when a few seconds of secure locking next to the base block the bushing in that position.

The foot lever is blocked and now serves as a handle to place the assembly in its final horizontal position, by means of an upward impulse. The rest of the effort will be done by the gravity itself, by unbalancing the axis of gravity of the whole.

The lower claw (or lower claws) is located at the junction between the floor and the wall of the window. The upper claw (or upper claws) will be located on the wall above the window. The boom with the reel will have crossed the window opening and is now on the outside. With one upper claw and one lower claw, they present a transversal cross. With three or more claws, this crosshead will not be indispensable.

When finally installing the accessory legs in the hole provided in the base of the set, the locking of the reel anchor is deactivated, allowing its controlled descent.

The set has, at least, a 360 ° camera strategically located for an ocular inspection, prior to rescue, by the rescue teams, to ensure their own safety.

The high end of the pen has a beacon light that warn its presence, both at the point of storage, and once the equipment is installed.

The unit, in a state of storage, is connected to a nearby power socket, for the charge of batteries necessary for the operation of its electronics and of all devices installed in it. In this case, a network of interior circuits will travel the whole, with connections at the destination points.

In buildings with particular facades, such as walls made entirely of glass or ironwork, which prevent notoriously the prudent installation of the whole, they will have a wall that is close to the storage area, with the necessary characteristics for the correct installation and activity of the invention.

DESCRIPTION OF A PREFERRED EMBODIMENT

Having already confirmed that there is no possibility of escape, and that the rescue teams can not reach our plant with their truck-scale or helicopter, we will review which façade is the least affected by fire or smoke.

Once the facade has been chosen, we will determine the optimum window for the installation of the invention (Figure 5). Another option is that there is a window specifically built for the invention on each façade. In that case that window will be used.

The harpoon is removed from its storage location by unplugging the connector from its base. When unplugging, or if the light of the building is gone, the intense continuous light of your headlight will reveal your position and allow us to see to operate with the harpoon.

We arrive at the window where we are going to install the harpoon (Figure 6). We will ask people to leave. We will step on the foot lever while holding the pen with the hand (Figure 7).

The upper blocks of the bushing are unlocked, allowing the bushing to lower and the divergent and equitable opening of the claws, with the help of their extensions. At that same moment, the foot lever is also locked in its handle position.

Once it has made its full travel, the bushing becomes blocked in the lower locks (Figure 8). We will make sure of it, forcing the claws down.

We will take the handle (old foot lever) and with an energetic movement we raise the set until its axis of gravity is unbalanced by the weight of the reel. At that moment, the set will take its horizontal position. Pull the handle towards us with reverse thrust, to control its final placement (Figure 10).

Next we will insert the bracket of the accessory legs in the hollow, now visible, in the back part of the set (Figure 11). When inserted, the reel locking rods are unlocked, starting their automatic descent (Figure 11). Simultaneously, the lighthouse begins to emit intermittent and intense flashes. These particular light signals will be recognized by the rescue teams as a "folding and folding arpon for mass rescue in buildings", undertaking the rescue measures trained for this case. Simultaneously, the 360 ° camera begins to emit.

The WIFI monitoring and decryption equipment will be connected to receive the video image from the 360 ° camera. The feasibility of the rescue is assessed. It is proposed that the reel has intercom equipment to establish verbal communication between trapped people and the rescue team. Both ends of the cable received by the reel will be taken once it has reached the ground. One end of the cable will receive a counterweight to facilitate rescue measures. The other end will be connected to a motorized watt reel, incorporated into the fire department's equipment, according to the measures to be taken for this case. The engine will be fast and powerful.

Once all the security measures have been taken for the rescuer, he will proceed to his ascent. It will be firmly attached to the cable and the motor will lift it to the "meeting" point. With it will take as many security measures, rescue and suffocation are necessary for an effective rescue.

The use of the cable with a motor on the ground makes the invention a massive rescue equipment.
