Description

The present invention relates to a security device allowing a evacuation of places frequented by a public, and this quickly and with security Max.

We know, in fact, that it is legally prescribed that places accessible to the public have, depending on their area, a greater or lesser number of emergency exits to allow, in case of problems in this place, a quick and secure evacuation of people inside.

These emergency exits must be easily identified by a sign bright, generally on a green background, resuming "emergency exit". he is also mandatory that these exit doors open outwards and be easy to operate easy and fast because it is obvious that any congestion, any jostling, and by that any loss of time, can have catastrophic consequences from the point of view loss of life especially when you consider that most problems, even few risk of causing panic among people inside building.

Similarly, in addition to these emergency exits, most of these places must be fitted with smoke detectors which, when activated by the fumes from of any combustion (fire), cause the triggering of a system, in general sound (siren or strident ringing), and the activation of watering sprays.

Other systems are also prescribed, namely fire extinguishers (powder or foam) of more or less large volumes, fire hoses with flexible hoses mounted on an unwinder and which, connected to a water pipe, can be put into service quickly by turning a control valve etc ...

However, it is recognized by the emergency services (firefighters, medical services) that a major problem generally arises in the event of a fire, namely the presence of smoke because, depending on the importance of the latter, it becomes very difficult if not impossible for people who have to evacuate places to distinguish light signs and by that emergency exits. Indeed either the irritation of the eyes no longer allows you to see around you, either the thick smoke released which, as everyone knows, rises and concentrates upwards, prevents distinguishing said luminous signs which are also at height, namely usually above the emergency exits. The same problem arises for rescue workers who must enter these places and who are also prevented from being located and to see both the configuration of the places and the places to reach to address the causes of the disaster as well as to be able to quickly bring help to people in distress knowing that any lost seconds can be of paramount importance.

The device described below provides a solution to the various drawbacks mentioned above.

This device consisting of an assembly included in one and the same housing is composed of a luminous sign as known but which advantageously includes a laser light system, which by definition is concentrated light having as particular property of marking itself in a light ray, of variable color depending on the color of the focusing lens used, on any obstacle it encounters and among others on smoke, dust and / or vapor being in the place and thanks to this property, it draw a light line that you set at the start so that it is slightly tilted towards inside the building and which is to be followed in its upward direction to help navigate to the emergency exits. This device also includes a sound system of the type classic, serving as an alarm signal but allowing, given its location in the case, to help solve the problem of lack of vision following the presence of smoke this so that people can go by hearing towards the emergency exits. This sound system also allows the visually impaired to find the direction to follow.

Likewise for the emergency services, precious help is brought to them by this laser beam because they just have to follow it towards its descending part so as to be able to locate and reach either the center of the building or the opposite wall.

Other features and characteristics of the invention will emerge from the description of an advantageous embodiment given below by way of nonlimiting example and with reference to the accompanying drawings.

• In Figure 1 the whole device.
• In figure 2 detail of the relay.

The device 1 as shown in FIG. 1, which is connected to the electrical sector, is located above the emergency exit or if the height does not allow it just against this last. It consists of a luminous sign 2 indicating "emergency exit", a laser beam emitter 3, sound system 4, emergency power 5 and of a relay 6 which, among other things, receives the control signals coming from the smoke 7.

This laser beam 3 included in the device should preferably be of class 1 or 2 therefore inherently harmless to sight, or possibly class 3 but this class presents more danger to the eyesight, but it is provided in all cases and this in order avoid any risk of physical damage, that the beam is emitted at an angle descending as far as possible to avoid receiving it in the eyes but it however, it must have sufficient inclination only to have a direction rising visible.

In operation, as soon as relay 6 receives the signal (electrical pulses) emitted by the smoke detector 7, it activates, for example by electromagnetic contact 14, the laser beam 3 via the contactor 101 as well as the audible signal 4 by through contactor 111. In order to facilitate orientation towards the emergency exits, it the laser beam 3 is intended to be directed slightly downwards and towards either middle of the width of the opposite wall either, if the distance is important and to keep a upward inclination sufficiently detectable, towards the middle of the ground surface of the building. This inclination of the laser beam 3 makes it possible to find the exact direction of the emergency exit since it suffices to go towards the rising part of said laser beam.

In addition to this laser beam 3 the sound signal 4 provides assistance additional to orient and auditoryly head towards the emergency exit.

In the event of a power failure only, but without the smoke detectors 7 are activated by some emission of smoke therefore with great danger less if not zero, a backup supply 5 of known type, such as for example accumulator, batteries etc ... included in each case, snaps, for example by electromagnetic contactor 14, via contactor 131 of relay 6. This emergency power supply controls the lighting of the illuminated sign 2 by the studs 9 thanks to the contactor 91 as well as the laser beam 3 by the studs 10 thanks to the contactor 101 but it does not activate the audible signal 4. Failure to engage the audible signal will avoid any panic on the part of the public present on the premises and will thus allow a possible evacuation with a reduced risk if not zero.

This type of laser light beam 3 would also be included in the boxes of the signs indicating the direction of the emergency exits (usually white arrow on green background) for example in corridors or rooms with no access direct to the outside. They would pursue the same goal and serve to direct people, step by step, towards the emergency exits and always following the direction rising laser beams 3.

Figure 2 shows in detail the composition of the relay assembly 6 in normal times. It includes, a connection 8 to the sector so as to provide, thanks to the contactor 91 in contact with terminals 9, lighting of the light panel 2, a contactor 101 facing but not in contact with the pads 10 for controlling the laser beam 3, a contactor 111 facing but not in contact with the studs 11 for controlling the sound signal 4, a contactor 121 face but not in contact with the pads 12 of the receiver of the signals emitted by the detectors of smoke 7, and a contactor 131 facing but not in contact with the studs 13 of emergency power supply 5 (accumulator etc ...).

Although a preferred embodiment of the device has been described and illustrated, it is Of course, other variants can also be applied while remaining within the framework of the inventive principle taken up.
